IDENTIFICATION OF MACHINES

A machine equipped with specified parts and fitted for a specific operation is given a STYLE NUMBER, the symbol for which is a number evenly divisible by 100, with a letter affixed. Example: 13200 A, 15800 D, 15900 D.

Styles of machines, similar in construction, are grouped and given a CLASS NUMBER, the symbol for which is a number evenly divisible by 100, without a letter affixed. Example: 13200, 15800, 15900.

Attached to each machine will be found a name plate, stamped with either the style number or the class number.

The measurement of the space between the rows of stitching made by styles in Class 13200 is represented by a gauge number. The spacing of the gauges is as follows: 2 gauge, 18 inch; 4 gauge, 3/16 inch.

ADJUSTING

GENERAL PLAN The steps necessary to readjust the machine or check its adjustment are given in the order most convenient for the machine fixer to follow.

The styles in Class 13200 use two needles and two loopers which make them slightly different from styles in Classes 15800 and 15900, which use only one needle and one looper. The instructions given apply directly to styles in Classes 15800 and 15900. Their application to styles in Class 13200 is a simple matter as the mechanism is practically the same. Where it differs, specific adjusting information is furnished.

In describing the positions or movements of the parts, there is but one point of view used. It is that of the operator sitting in front of the machine.

FORMATION OF THE

The accompanying illustrations "DOUBLE LOCKED STITCH" show the three steps in the formation of the "double locked stitch." A careful study of them and the explanatory matter will be of considerable assistance in making an adjustment. Frequent references to these illustrations are made.

The needle carries its thread down through the fabric and, as it ascends, throws out a loop at the rear, which the looper enters as

ADJUSTING

shown in Fig. 1. While the needle is above the throat plate, the feed dog moves the fabric to the rear, the looper rocks to the front across the path of the needle and returns to the right, forming a triangular space—bounded by the back of the looper, the looper thread on the left and the needle thread on the right—into which the needle descends with its thread, as shown in Fig. 2. The looper, continuing to return to the right, leaves the stitch on the needle, as shown in Fig. 3. The needle, again ascending, recedes from the stitch, which is tightened in the fabric by the action of the looper as it forms the next stitch.

The tension applied to the needle thread controls the tightness of the stitches.

CAUTION When a machine fails to work satisfactorily, though apparently in good repair, it is possible that some minor trouble exists. For this reason, delay may be avoided by acting on the following suggestions:

(1) Check the machine according to operating instructions under the subject "Useful Hints" in Catalog No. 51 A.
(2) See that the needle thread tensions are as tight as is consistent with the strength of the thread. See that the looper thread tensions are quite loose. The looper threads require only a slight tension, barely enough to steady them in passing through the machine.
(3) The throat plate needle hole, thread eyelet, tension discs, and needle thread take-up may have become roughened or grooved, which will cause breaking of both the needle and looper threads. It can be remedied by smoothing the surfaces with emery cloth.
(4) Unravel the stitching and note if the threads are cut or injured. The teeth of the feed dog may be cutting the stitch on the under surface of the fabric.
(5) Before operating by power, after any change has been made in the working parts, always turn the machine by hand, to be sure that it runs freely and that the working parts do not interfere with the frame or with each other.

If the foregoing suggestions fail, the adjustment should be checked with the following instructions. While many variations can be made, the best results will be secured by following them.

ACCESSIBILITY To secure an unobstructed view of the looper, remove the cloth plate and looper needle guard.

Note: In adjusting machines, always use a new needle.

NEEDLE REAR GUARD This forces the needle into proper position, should it glance toward the rear of the machine in passing

ADJUSTING

through the fabric. Three types are used in the machines covered by this catalog.

Styles 15900 A, 15900 D, and 15900 E are equipped with a stationary type. It is fastened in a seat milled in the under side of the throat plate. A slight variation in its position can be secured by slightly loosening the screw and forcing the guard in the desired direction while the screw is retightened. It is set correctly when its vertical face barely touches the rear of the needle.

Styles 15800 D, 15800 E and 15800 G are also equipped with a stationary type, adjustably secured to the lower knife support. It is set correctly when its vertical face barely touches the rear of the needle.

Styles in Class 13200, Styles 15800 A and 15800 B are equipped with a moving type secured to the feed bar. It is set correctly when its vertical face or faces barely touch the rear of the needle when the guard is at its extreme forward position.

As it moves with the feed dog, the guard must be readjusted each time the length of the stitch is altered.

The needle bar in styles in Class 13200 should be turned in its bearings so that the oblique position of the needles corresponds with the oblique position of the two vertical faces of the needle rear guard.

LOOPER COLLARS These are placed over the shanks of loopers in Styles 13200 A, 15900 D, and 15900 E. They are furnished in three thicknesses. No. 21210 is .040 inch thick, No. 21210 A is .020 inch thick, and No. 21211 is .054 inch thick. Additional variations can be secured by driving the collar into the end of a wooden block and reducing its thickness with a file. The collars used should be of sufficient thickness so that when the loopers are seated in the looper rocker, the smallest space between the top of the loopers and underside of throat plate, when the loopers are in their highest position, is just enough to pass a double thickness of newspaper.

NEEDLE AND LOOPER Three adjustments are necessary to bring these in proper time.

FIRST The space between the center of the needle and ADJUSTMENT point of the looper, when the needle is at its lowest position, should be 7/32 inch. This space controls the size and form of needle loop. A very convenient manner of securing an accurate adjustment will be found by using a looper adjusting gauge No. 21225-7/32, having a "V" slot, the center of which is 7/32 inch from the edge of the wider side, as indicated by the dotted line in the cut. In using this gauge, hold it with the "V" slot enclosing

ADJUSTING

the front of the needle, with the wider side of the gauge to the right. Then, the needle being at its lowest position, the point of the looper should be made to come even with the right-hand edge of the gauge

by turning the looper connecting rod, which is provided with right and left threads. To loosen nuts, use wrench No. 21388 and turn them to the rear. In tightening the looper connecting rod nuts, care should be taken to see that

Black-and-white illustration of a wooden plank with a hole and textured surface (no text or symbols)

21225-7½

the left ball joint has side play in all positions. First tighten the left nut securely. Then, turn the pulley in the operative direction till the long straight edge of the looper thread take-up is in its front vertical position and tighten the right-hand nut securely. Again apply the gauge to make sure that the adjustment has not been altered.

The front looper of styles in Class 13200 should likewise be set to the 7/32 inch gauge. With this adjustment of the front looper, the distance from the point of the back looper to the center of the back needle should be approximately the same. If the distance is greater, set the back looper to the looper gauge by turning the looper connecting rod.

SECOND To set the needle at its proper height with respect to the looper, turn the machine pulley in its operative direction till the point of the looper, moving from right to left, is even with the left side of the needle. Then the measurement from the under side of the looper to the upper edge of the needle eye should be 1/64 inch for Styles 15800 A, 15900 D, and 15900 E; 1/32 inch for Style 15900 A; and 3/64 inch for Styles 13200 A, 15800 D, 15800 E and 15800 G. Enough variation is allowable to have the upper edge of the needle eye 1/64 inch lower than the foregoing measurements, without interfering with the functions of the loopers and needles, as shown in Figs. 1 and 2, respectively, of the stitch formation. The adjustment is made by moving the needle bar.

Care should be taken when adjusting styles in Class 13200 to avoid turning the needle bar in its bearings, as that will destroy the oblique adjustment of the needles. An excellent plan is as follows: Place the fingers of the left hand back of the presser guide bar bearings, and press the thumb firmly against the front of the needle bar. With the right hand, loosen the two needle bar set screws, and turn the pulley so that the needle bar connection will be moved upward if the needle bar is to be lowered; turn the pulley in the opposite direction if the needle bar is to be raised.

ADJUSTING

THIRD When the looper moves to the left to enter the ADJUSTMENT needle loop as shown in Fig. 1 of the stitch formation, there should be approximately .010 inch space between the looper point and the back of the needle. A space of .010 inch is easily visualized by cutting three plies of newspaper simultaneously with a pair of sharp scissors and bringing the cut edge into view by holding the paper together with both hands. A variation from .005 to .0156 (1/64 inch) is allowable. To adjust the position of the looper, turn the pulley till the looper point is directly behind the needle; loosen the two screws which hold the looper rock shaft frame to the bed; move the frame to the front till the looper point noticeably deflects the needle; tighten the screws slightly to force the frame into a level position; tap the frame backward to the desired position with the handle of a screw driver; retighten the frame screws securely.

A small piece of white paper placed to the left of the needle as a background will be found convenient in making this adjustment.

NEEDLE FRONT A guard is attached to the looper to force the GUARD needle into its proper position should it glance toward the front of the machine in passing through the fabric. The guard is set correctly when it barely passes the needle without striking it. The screw hole is elongated to permit this adjustment.

On styles in Class 13200, the foregoing applies only to the front looper.

LOOPER THREAD TAKE-UP Near the middle of the main shaft AND CAST-OFF WIRE is located a device for controlling the looper thread. It consists of a take-up, cast-off wire, and take-up thread eyelet. Their function is to hold the looper thread taut till the descending needle point has passed below the looper thread as shown in Fig. 2 of the stitch formation, and continue to hold the thread till the eye of the looper is to the left of the middle of the needle, then release it.

A simple test to determine whether they are in adjustment can be made as follows: Take hold of the looper thread on the left side of the thread eyelet, draw it slowly through the eyelet, and while so doing, turn the machine pulley in its operative direction, until the thread moves from the long straight edge of the take-up to the circular edge. Stop at this point. The needle point should be below the middle of the looper. Enough variation is allowable to have the point even with the lower edge of the looper.

The prongs of the take-up thread eyelet, which project over the main shaft, are set correctly when they just clear the main shaft

ADJUSTING

sleeves. To change the height of the prongs, loosen the lock nut on the stop screw and change the position of the stop screw in the take-up thread eyelet holder.

INTERMITTENT LOOPER THREAD NIPPER SPRINGS

Attached to the front side of the main shaft middle bearing is a pair of nipper springs, which clamp the looper thread when the looper is moving to the right. Their purpose is to prevent the take-up from drawing additional looper thread through the tension instead of holding taut the thread where it passes from the looper eye to the throat plate needle hole as shown in Fig. 2 of the stitch formation. They are set correctly when they begin to clamp the thread as soon as the looper has completed its movement to the left and returned about 1/64 inch. Their operation can readily be observed by threading the machine in the regular manner and drawing the thread, care being taken to leave some slack between the tension and the nipper springs. The adjustment is made by changing the position of the operating arm on the looper rock shaft.

NEEDLE BAR Fastened to the needle bar is a thread nipper. THREAD NIPPER Its purpose is to counteract the elasticity of the needle thread and enable the needle to throw out steady loops. The slightest appreciable tension is all that is required. The adjustment is made by lengthening or shortening the spring.

FEED DOGS It is important that the feed dog be set at just the proper height above the throat plate. If the tips of the teeth do not rise high enough, imperfect feeding of the work will result. If they rise too high, imperfect feeding of the work will likewise result, because the teeth will remain in contact with the fabric after the motion of the feed dog has reversed. The feed dogs should be set so that the tips of their teeth will rise approximately 3/64 inch above the throat plate. Variations to insure proper feeding and consistent with the fabric are allowable. There are two types of feeding mechanism used in machines covered by this catalog, non-differential and differential.

NON-DIFFERENTIAL FEEDING MECHANISM This consists of a single feed dog adjustably secured to the feed bar. Its height is maintained by a supporting screw under the feed dog.

DIFFERENTIAL This consists of two feed dogs, a main FEEDING MECHANISM feed dog and a differential feed dog. They are both adjustably secured to their respective feed bars. The differential feed bar is driven by a link, adjustably secured by a

ADJUSTING

stud to a slot in the feed rocker. When the stud is in its lowest position in the slot, the differential feed dog travels in unison with the main feed dog. The desired differential motion can be obtained by raising the stud. If the travel of the differential feed dog relative to the main feed dog is too long, it will gather or shorten the fabric at the seams. If its travel is too short, it will stretch or lengthen the fabric. Care should be taken to see that the feed dogs do not strike the ends of the throat plate slots.

PRESSURE On top of the machine near the middle will be found a thumb screw for regulating the pressure of the presser foot on the fabric. Only sufficient pressure is required to enable the machine to feed properly and to firmly hold the fabric while the needles are being withdrawn. Care should be taken to avoid tightening the screw to the extent that the spring rests on the machine bed because this condition will decrease the pressure.

TENSIONS The importance of properly adjusted tensions can scarcely be over-estimated. Not only the required tightness or looseness of the stitches, but their uniform appearance is dependent on this adjustment.

For stitching inelastic fabrics, the tension on the needle threads should be as tight as is consistent with their strength and avoid puckering the fabric. For stitching elastic fabric such as knitted goods, the tension on the needle threads should be considerably less to secure the desired elasticity in the stitches.

The tension on the looper threads should be very slight; only sufficient to steady them in passing through the machine.

THREAD For regular stitching, the needle thread should be two or three sizes larger than the looper thread. While a glaze or soft finish thread can be used in the needle, a soft finish is always preferable in the looper.

NEEDLE THREAD While only one type of needle thread controller is used on each machine, two types are used on the machines covered by this catalog. The automatic type is used on machines in Classes 13200 and 15900 and the non automatic type on machines in Class 15800.

AUTOMATIC NEEDLE On the upper part of the machine will THREAD CONTROLLER be found a lever, connected with the presser bar. It carries a guide for the needle thread at its right-hand end, which co-operates with two eyelets fastened to the needle lever, one to the right and the other to the left.

ADJUSTING

Its purpose is to take up the slack in the needle thread while the looper is returning to the right. As it is connected with the presser bar, it automatically adjusts itself for any thickness of fabric; that is, when the presser foot ascends or descends, as thicker or thinner fabric passes under it, the thread controller guide moves in the opposite direction, and takes up a decreased amount of slack on the thicker fabric, or an increased amount on the thinner fabric.

The adjustment can only be made by threading the machine and running it on the fabric.

Where a tight seam is required, which necessitates a tension on the needle thread as tight as consistent with its strength, the thread controller guide should be set so that, when the needle is at its lowest position, there will be the smallest noticeable slack in the thread. If there is no slack the thread controller guide may have to be lowered, as the needle, moving at full speed, descends a trifle farther and the strain at the eye will cause frequent breaking of the thread. If there is more than 1/16 inch of slack, the guide may have to be raised; otherwise, the stitch around the needle will remain below the throat plate and will interfere with the formation of the needle loop, as the looper moves to the left in the formation of the new stitch.

Where a comparatively loose tension is required to avoid puckering the fabric, or for operations where the machine has to continue to make stitches, after the fabric has passed beyond the needle, the thread controller guide should be set a trifle higher.

The position of the guide is altered by moving the rack on the presser bar.

If any needle thread is drawn through the tension as the needle descends, it may be accurately observed while turning the pulley by hand.

To ascertain the amount of slack in the needle thread, turn the pulley till the needle passes down through the fabric to its lowest position, place the fingers on the thread a short distance above the needle clamp nut, and draw upward.

The thread controller guide should never be set so that it will descend lower than 1/32 inch below a straight line connecting the two eyelets on the needle lever, when the needle is at its highest position and the presser foot is bearing on the thickest part of the work, as its action would be interfered with.

NON-AUTOMATIC NEEDLE THREAD CONTROLLER

Its purpose is the same as the automatic type except that it is non-automatic in operation. It is usually set as high as its slot will permit.

ADJUSTING

REGULATING

LENGTH OF STITCH

This is accomplished at the left end of the main shaft. There, three screws in a row will be found with a lock nut to the left of them. The length of stitch is altered by loosening the nut and turning the stitch regulating screw which is the largest of the three. Turning it to the right lengthens the stitch, and turning to the left shortens it. To loosen nut, use screw driver wrench No. 21206 and turn it in the direction the machine runs. Apply the wrench with the left hand and hold the machine pulley with the right hand.

Always tighten the lock nut after any change has been made. Note the effect of turning the stitch regulating screw. If it is turned too far to the right, the feed dogs will strike the ends of the slots in the throat plate. If it is turned too far to the left, the machine will feed the work towards the operator.

Each time the length of stitch is altered on machines having a needle rear guard attached to the feed bar, the guard must be readjusted to compensate for the change.

SETTING BINDING ATTACHMENT

It should be set as close to the needle as possible in order to maintain the sewing margin

on both convex and concave edges. The attachment should also be set as low as possible so that the body fabric feeds through the middle of the delivering end. The sewing margin can be varied on either side of the binding by tilting the attachment. Tilting the delivering end of the attachment upwardly decreases the margin on the top of the binding and increases the margin on the bottom tilting the delivering end downwardly acts the reverse.

TRIMMING MECHANISM

DESCRIPTION While only one type of trimming mechanism is used on each machine, two types are used on machines covered by this catalog. Styles in Class 13200 and Styles 15800 A and 15800 B are fitted with the spring-pressed knife engagement type. Styles 15800 D, 15800 E, and 15800 G are fitted with the fixed knife engagement type.

SPRING-PRESSED KNIFE The upper knife is spring-pressed ENGAGEMENT TYPE against the lower knife, the pressure being regulated by means of the spring chamber, Catalog No. 15876. To increase the pressure, loosen the clamp screw on the spring chamber and move the chamber to the right. Tighten the clamp screw after each adjustment. Only sufficient pressure should be applied to enable the knives to cut properly, any additional pressure will necessitate resharpening at shorter intervals.

To accurately set the knife bar locking bolt, it is provided with a bushing having a right-hand internal and a left-hand external thread. To take up the wear, loosen the set screw and turn the bushing to the left.

On the right-hand end of the upper knife bar shaft will be found a locking lever, adjustably secured by a clamp screw. It should be set so that it will mesh with the upper knife bar shaft locking lever block when the upper knife bar is raised to its extreme non-operative position.

The left side of the upper knife must be square with the throat plate. The upper knife should be set so that it is deflected the smallest noticeable amount to the right as it passes the cutting edge of the lower knife. Should it be necessary to make either of these adjustments, lock the upper knife bar in operative position, apply a wrench to the front of the upper knife bar, force the upper knife to the right, and twist as required; care being taken not to break the guiding toe of the upper knife.

FIXED KNIFE The upper knife is fixed laterally. It ENGAGEMENT TYPE should be set so that it bears lightly against the lower knife. Only sufficient pressure should be applied to enable the knives to cut properly, any additional pressure will necessitate resharpening at shorter intervals.

The left side of the upper knife must be square with the throat plate. The upper knife should be set so that it is deflected the

TRIMMING MECHANISM

smallest noticeable amount to the right as it passes the cutting edge of the lower knife.

The upper knife bar locking lever is adjustably secured on the rock shaft by a clamp screw. The relative position of the lever on the shaft should be such as to permit the lowest part of the upper knife bar carrier, Catalog No. 15872 A, when in operation, to descend within 78 inch of the top of the cloth plate cover.

SETTING THE KNIVES Instructions relative to setting the knives are given under that subject in Catalog No. 51 A.

CHANGING THE KNIVES There is no economy in putting in only one resharpened knife because a new cutting edge, operating with an old one, will become dull after a comparatively short service. The small amount of grinding required when they are only slightly dulled more than compensates for the labor of changing them.

Resharpened knives should be put in at regular intervals without regard to the service the old ones have performed. Unsatisfactory work due to the operator's failure to notice that the knives are not cutting properly will be avoided. The interval will necessarily depend on the class of goods being cut, and on the lateral pressure of the upper knife against the lower one. In many factories, operators are given a few sets of knives and they make the change at regular intervals.

CHANGING WIDTH On machines fitted with a trimming mechanism, the width of seam is changed by laterally moving the lower knife support.

On machines fitted with the spring-pressed knife engagement trimming mechanism, loosen the clamp screw at the front of the cloth plate and turn the adjusting screw at the left end of the cloth plate. Turning the adjusting screw to the right decreases the width of seam, and turning it to the left acts the reverse. Tighten the clamp screw after the adjustment has been made. In decreasing the width of seam, care should be taken to see that the lower knife is not sprung by being drawn against the throat plate. In increasing the width of seam, raise the upper knife out of operative position to prevent the guiding toe from being broken. The upper knife and front cover diverting guide being spring-pressed against the lower knife, automatically adjust themselves with each change in the width of seam.

On machines fitted with the fixed knife engagement trimming mechanism, remove the cloth plate, loosen the screws which hold the lower knife support to the bed, and turn the adjusting screw at the

TRIMMING MECHANISM

left end of the machine. Turning the adjusting screw to the right decreases the width of seam, and turning it to the left acts the reverse. Tighten the lower knife support screws after the adjustment has been made. Reset the upper knife. The widths of seam that can be obtained from the various combinations of throat plates and lower knives, when the lower knife is tight against the throat plate, which is its most favorable location, are as follows:

Style of Machine	Throat Plate	Knife	Width of Seam
15800 D	15824 D	15849 D	1/8 inch

KNIFE GRINDER

DESCRIPTION There are two types of knife grinders. No. 15898 B is for knives used with the spring-pressed knife engagement trim-

ming mechanism as found in styles in Class 13200 and Styles15800 A and 15800B. No. 15898D is for knives used with the fixed knife engagement trimming mechanism as found in Styles 15800 D, 15800 E, and 15800 G.

INSTALLATION Knife grinders are not in- cluded in standard equipment, but either type can be furnished at the price listed. It may be set on the sew- ing machine table and driven by an ordinary

15898B

transmitter or may be driven from an overhead shaft. If a transmitter is used, it should be fastened to the underside of the table slightly back of the grinder so that the front part of the belt will not interfere with the grinder frame.

SPEED The diameter of the grinder pulley is two inches. To make a smooth cutting edge and leave the burrs on the opposite side, the top of the wheel should turn toward the cutting edge of the knife. The speed of the emery wheel should be at least 3500 R.P.M., but not exceed 5000 R.P.M., although it may be safely driven at 8000 R.P.M. A speed of less than 3500 R.P.M. will allow the knives to cut the emery wheel, while a speed greater than 5000 R.P.M. will require exceptionally great care to avoid drawing the temper.

GRINDING THE KNIVES A swinging frame adjustable to and from the emery wheel by a thumb screw, is provided to automatically position the knives at the correct angle. Light cuts should be taken otherwise the temper of the knife will be drawn.

KNIFE GRINDER

The upper and lower knives should be ground alternately for the reason that grinding the lower knife tends to keep the right-hand corner of the emery wheel square.

If the emery wheel becomes rounded, an emery wheel dresser or a coarse file should be applied; the latter can be used only by turning the wheel by hand.

It is not advisable to use this knife grinder for scissors, tools, or machine parts. A small utility grinder No. 21394 can be furnished at a slight cost for miscellaneous grinding.

15898D

If preferred, the knives may be sent to our nearest office, where the grinding will be done promptly for a nominal charge.

GRINDING LOWER KNIVES

The lower knives, used with both types of trimming mechanism, are ground in practi-

cally the same manner. Clamp the knife in the left opening of the swinging frame and swing the knife across the face of the wheel. If after taking a cut to the left and back to the right across the end of a dull knife, it is not found sharp enough, unclamp the knife, push it against the positioning lever, reclamp it, raise the lever and take another cut. This method will permit additional cuts of the same size without any danger of grinding away the frame or drawing the temper. Care should be taken to see that the looper clearance is maintained on lower knives used with the fixed knife engagement trimming mechanism.

To those accustomed to grinding knives, the positioning lever may be dispensed with and the thumb screw used, thereby simplifying the operation.

GRINDING UPPER KNIVES

trimming mechanism.

There is considerable variation in the design of the upper knife used with each type of They are therefore taken up separately.

KNIFE GRINDER

The upper knife, used with the spring-pressed knife engagement trimming mechanism, is clamped in the right-hand opening. The stop regulating screw should be set to avoid cutting away the guiding toe. To secure a square corner between the cutting edge and guiding toe, the right-hand corner of the emery wheel should be kept square.

The length of the guiding toe should be equal to the travel of the upper knife plus 18 inch.

The above applies to the upper knife, used with the fixed knife engagement trimming mechanism. The bevel of this knife should be maintained to the extent that its cutting edge will not exceed 1/32 inch in thickness. The bevel on the right-hand side of the front edge should also be maintained to deflect the parings where heavy cuts have to be taken. When the left side of the guiding toe becomes worn so that its thickness is noticeably reduced, it will be preferable to grind off the toe and make an entirely new cutting edge.

REPAIRING

LAPPING BEARINGS Use only powdered oil stone for this process. When finished, clean the parts thoroughly with gasoline and run them in oil.

Powdered emery or crocus should never be used because they cannot be thoroughly washed out, and what is retained in the pores of the metal will continue indefinitely the grinding process.

The bearings of the needle lever connection and all similar parts are left a trifle small to allow for their being lapped together with their associated parts.

PLUS SIZES The main shaft, needle lever stud, feed rocker shaft, presser bar, and presser guide bar are made in plus sizes for use where bearings have been worn (see list of parts).

In assembling a plus size needle lever stud in a needle lever, ream the needle lever with taper reamer No. Y 800 allowing 1/32 inch from inside of stud head to hub face of needle lever for lapping in. Clean thoroughly after lapping together.

In assembling a plus size needle lever stud in machine frame, place the needle lever and stud in position and note how far the stud extends. Remove and ream bed with taper reamer No. Y 801 till the space between the inside of the stud head and the hub face of needle lever is 7/32 inch when the needle lever is held against the frame. Draw the needle lever stud into position by turning the nut.

RENEWABLE BEARINGS These are provided for the needle bar. Being retained in position by a clamp screw, they can be easily replaced when worn. It is advisable to use bearings with an internal diameter of .197 inch and ream them to the standard internal diameter .200 inch after they are clamped in position. Without specific instructions regarding their internal diameter, they will be furnished to fit the needle bar of standard size .200 inch.

CAUTION Care should be taken to avoid breaking the frame when removing a bearing. Do not pry open the slit with a screw driver or similar tool. A better plan is to loosen the screw and push or tap it out from the under side.

TENSION NUTS When a nut becomes too loose to maintain its position, turn it on the post as far as possible, and slightly spread the slotted end.

REPAIRING

FEED BAR SHOE A reversible hardened steel shoe is secured to the underside of the feed bar to take the wear of the feed lift eccentric.

SHARPENING FEED When the teeth of a feed dog have become DOGS dull, it may then be annealed, re-sharpened and re-hardened. For removing sharp edges of the teeth, a small triangular piece of oil stone will be found convenient.

ASSEMBLING To maintain the take-up and eccentric in proper relation, the main shaft is spotted. The position of these parts must not be changed.

Beginning with the eccentricis at the left, the feed lift eccentric is assembled with its catalog number to the right. The looper eccentric is likewise assembled with its catalog number to the right. In styles in Class 13200 and Styles 15800 A and 15800 B, the knife eccentric is assembled with its hub to the left; the second screw coming into view as the eccentric is turned in its operative direction, is placed in the time spot. The take-up is assembled so that its edges will rotate in the following order: (1) Long straight edge, (2) circular edge, and (3) short straight edge. The needle lever eccentric and balance weight is assembled with the balance weight on the right; the first screw coming into view as the balance weight is turned in its operative direction is placed in the time spot. In Styles 15800 D, 15800 E and 15800 G, the knife eccentric is assembled with its hub to the right; the first screw coming into view as the eccentric is turned in its operative direction, is placed in the time groove. The hub of this eccentric serves as a collar and the groove in the shaft permits lateral adjustment. The remaining styles not having this knife eccentric to the right of the needle lever eccentric, have a collar which is placed against the frame to prevent end play to the right. Before tightening the set screw in the collar or knife eccentric, place two pieces of newspaper between the hub of the needle lever eccentric and the middle bearing; slide the main shaft so that the paper is pressed against the bearing and hold firmly in this position till the knife eccentric or collar, as the case may be, is secured in position, snug against the frame. Withdraw the paper; this will provide the proper clearance between the eccentric and bearing. The machine pulley is then placed on the right-hand end of the main shaft and brought snug against the frame, thus preventing end play to the left.

The needle bar is fitted correctly in its bearings when it falls slowly of its own weight. The needle lever stud should be tightened so that the left end of the lever also falls slowly of its own weight

REPAIRING

If, after connecting the lever with the needle bar, the parts do not fall, obviously the lever is not in line. By withdrawing the needle lever link, the direction in which the lever should be bent can be readily seen.

The tube, No. 1230 C, of the needle lever connection should be adjusted so that the distance between the centers of the needle lever eccentric and needle lever ball stud is 434 inches.

The needle lever ball should be turned so that a small space will be left between the buffer and the upper bearing when the bearing is at its highest position. Tighten the clamp nut securely.
