ILLUSTRATIONS

This manual has been arranged to simplify ordering repair parts. Exploded views of various sections of the mechanism are shown so that the parts may be seen in their actual position in the machine. On the page opposite the illustration will be found a listing of the parts with their part numbers, description and the number of pieces required in the particular view being shown.

Numbers in the first column are reference numbers only, and merely indicate the position of the part in the illustration. The reference number should never be used in ordering parts. Always use the part number listed in the second column.

Component parts of sub-assemblies which can be furnished for repairs are indicated by indenting their descriptions under the description of the main sub-assembly. As an example refer to the following text.

  1. 29126 EC Upper Looper Drive Shaft Assembly 1
  2. 22503 F Screw 1
  3. 39543 E Cam Follower Locking Clamp 1

It will be noted in the previous example that the cam follower, bushing and cam guide and the upper looper drive shaft are not listed. The reason is that replacement of these parts individually is not recommended, so the complete upper looper drive shaft assembly should be ordered.

When a part is common to all machines covered in this manual, no specific usage will be mentioned in the description. However, when the parts for the various machines are not the same, the specific usage will be mentioned in the description and, if necessary, the difference will be shown in the illustration.

A numerical index of all the parts shown in this manual is located at the back. This will facilitate locating the illustration and description when only a part number is known.

IDENTIFYING PARTS

Where the construction permits, each part is marked with its part number. On some of the smaller parts and on those where construction does not permit, an identification letter is marked in to distinguish the part from similar ones.

PLEASE NOTE: Part numbers represent the same part, regardless of which manual they appear. On all orders please include part number, name and style of machine for which the part was ordered.

Table I NEEDLES

Selection of proper needle size is determined by size of thread used. Thread should pass freely through the needle eye in order to produce a good stitch formation.

Each needle has both a type and size number. The type number denotes the kind of shank, point, length, groove, finish and other details. The size number, stamped on the needle shank, denotes largest diameter of blade, measured midway between shank and eye. Collectively, type and size number represent the complete symbol which is given on the label of all needles packaged and sold by UNION SPECIAL. See "STYLE OF MACHINES" for the standard recommended needle type & size for your machine.

To have needle orders promptly and accurately filled, an empty package, a sample needle, or the type and size number should be forwarded. Use the description on the label. A complete order would read: "1000 Needles, Type 130GS, Size 140/054".

LUBRICATION

The oil has been drained from the machine before shipping and the reservoirs must be filled before beginning to operate. Use a straight mineral oil with a Saybolt viscosity of 90 to 125 seconds at 100° Fahrenheit. Union Special Part No. 28604R.

Oil is filled at oil caps (A & D, Fig. 1). The level is checked at sight gauges (B) and (E). Maintain the oil level between the red lines of the gauges.

The machine is equipped with a continuous running rotary driven oil pump. The action of the oil can be observed through oil sight (A) and (D) in the front and back top covers.

When starting a new machine, filling the reservoirs or when beginning to operate a machine that has been idle for some time, it may be necessary to prime the pump. To do this, remove the two plug screws (C). Apply oil to these holes and operate machine until bubbling can be observed at the windows. Replace screws (C).

CAUTION: If oil does not bubble when machine is running, the circulating pump is inoperative.

Oil may be drained from the machine at two places, plug screw (F) located in the bottom of the cylinder and plug screw (G) at the back of the main frame below the handwheel.

THREADING

A convenient means for threading the looper has been provided. When loopers are at the left end of their travel, press the knob (H, Fig. 1) and loopers will back out of position, leaving them easily accessible. Thread the machine as illustrated in (Fig. 1). After threading, push loopers back into position.

ADJUSTING INSTRUCTIONS

NOTE: Instructions stating direction of location, such as right, left, front or rear of machine, are given relative to operator's position at the machine. The handwheel rotates counterclockwise, in operating direction; when viewed from the right end of machine.

SYNCHRONIZING NEEDLE AND LOOPER MOTIONS

Union Special 35800BWDRG - SYNCHRONIZING NEEDLE AND LOOPER MOTIONS - 1

text_image A243-94

FIG. 2

NOTE: Needle and looper mechanisms are carefully synchronized with precision gauges before leaving the factory to insure the best possible sewing conditions.

Should it become necessary to disassemble the main shaft or replace components of the needle or looper drive mechanisms, re-synchronization of the machine will be required to facilitate proper sewing adjustments. This is accomplished by means of an adjustable split coupling located beneath the rear top cover, connecting the crankshaft to the main shaft, which in turn drives the looper mechanism.

To synchronize the machine, remove the needles, presser foot, throat plate, feed dogs and upper feed roller mechanism. Rotate handwheel in the operating direction until the needle bar is at the bottom of its stroke and just begins its upward travel. Loosen screw (A, Fig. 2) and remove the looper for the left hand needle from the looper holder. Insert a straight steel rod (B) 5/32" (3.9mm) or 11/64" (4.3mm) diameter by 2-1/2" (63.5mm) long into looper holder and retighten screw (A). It may be necessary to reposition the looper holder so that the rod (B) will be in a vertical position when at its farthest travel to the right. Rotate the handwheel until the rod is at extreme left, reinstall the throat plate. Turn the handwheel in the operating direction, with needle bar rising until rod (B) comes in contact with the edge of the throat plate. At this point, clamp Union Special timing gauge TT147 (C) around the needle bar (D), flush against the underside of the machine casting (E). Rotate handwheel in the opposite direction until either the gauge contacts the machine casting on the up stroke of the needle bar or the rod contacts the edge of the throat plate. Maximum allowable clearance between gauge and casting or rod and throat plate is .005" (0.1mm)

Union Special 35800BWDRG - SYNCHRONIZING NEEDLE AND LOOPER MOTIONS - 2

text_image A247-94 A B C

FIG. 3

If machine is not synchronized the following applies:

Both ends of the adjustable split coupling are secured to the crankshaft and main shaft by spot screws and set screws. On the main shaft end of the coupling (A, Fig. 3) three screws (B) thread horizontally through the coupling. The holes in the main shaft end of the coupling are larger than the diameter of the screws, permitting several degrees of rotation in either direction to properly synchronize the needle and looper. Loosen the three horizontal clamp screws (B, Fig. 3). With rod (B, Fig. 2) at its farthest position to the left, snug the uppermost horizontal clamp screw enough to hold coupling (A, Fig. 3) in position. If the handwheel is turned in reverse of operating direction and gauge (C, Fig. 2) on needle bar (D) contacts the machine casting (E) before rod (B) contacts the edge of the throat plate, loosen horizontal clamp screw (B, Fig. 3) which was snug, while holding the coupling in place with an Allen wrench in set screw (C). Rotate the handwheel slightly in reverse of operating direction, snug the uppermost horizontal clamp screw (B), recheck synchronization. If the handwheel is turned in reverse of operating direction and the rod contacts the edge of the throat plate before the clamp gauge contacts the machine casting, adjust as before, except turn the handwheel slightly in the operating direction. Use shim stock to insure no more than .005" (0.1mm) exists between gauge and casting or between rod and throat plate, in both the operating and reverse directions of the handwheel. When this setting has been made, tighten the three horizontal clamp screws (B, Fig. 3) securely, and recheck both clearance points with .005" (0.1mm) shim gauge to assure no slippage occurred while tightening the screws.

TIGHTENING NEEDLE HEAD

When replacement of the needle bar, and or needle head is necessary, torque the needle head to needle bar 14-16 in. lbs. (1.6-1.8Nm) or use torque rod No. 21227AR that has been supplied with the machine, for the purpose of eliminating the possibility of distorting the needle bar due to overtightening. Insert the torque rod in the hole at the upper end of the needle bar, while holding the needle bar head with a suitable tool, turn the needle bar with the torque rod onto the needle bar head. When the rod starts to bend, the needle bar head has been threaded into the needle bar properly.

ALIGNING NEEDLES IN THROAT PLATE SLOTS

Insert a new set of needles, type and size specified, with screw (B, Fig. 4) slightly loosened, lower needle bar (A) and turn needle head as required until the needles are centered in the throat plate needle hole slots. Tighten screw (B) torque to 19-21in.lbs. (2.1-2.4Nm).

NOTE: If the needles cannot be aligned in the throat plate slots, the lower cylinder must be moved as stated below.

CENTERING THE CYLINDER

Remove the top front cover and gasket from the main frame. Loosen cylinder holding screw (A, Fig. 5). Turn eccentric screw (B) clockwise or counterclockwise to move the cylinder so the needles are centered in the needle holes. Tighten screw (A) and recheck settings.

NOTE: The cylinder may not move freely when the eccentric is turned because the joint sealant compound has set.

SETTING THE LOOPER

Insert a new set of needles, type and size specified. Always adjust the looper (A, Fig. 6) for the left needle first. Set the looper so that the distance from the center of the needle (B) to the point of the looper (A) is 9/64" (3.6mm) when the looper is at its farthest position to the left. Looper gauge (C) No. 21225-9/64 can be used advantageously in making this adjustment. If adjustment is required, loosen screw (A, Fig. 7) in looper holder, permitting movement in either direction to attain the 9/64" (3.6mm) dimension as shown in Fig. 6. Retighten screw (A, Fig. 7). Repeat for other needles and loopers.

Rotate handwheel in operating direction to assure that the looper point passes to the rear of the needle to touch but not to deflect the needle. This adjustment can be made by loosening screw (A, Fig. 7) in looper holder. Looper holder can be moved front to back to attain looper to needle setting. Always check the 9/64" (3.6mm) looper gauge setting after setting the looper to the back of the needle, and conversely, always check the setting of the looper to the back of the needle after setting the 9/64" (3.6mm) looper gauge.

The amount of looper avoid has been set at the factory to .110" (2.8mm). If it becomes necessary to adjust the amount of avoid it is recommended as a starting point, to have the points of the descending needles contact the back of the lower 1/3 of the back of the looper blade. (See Fig. 7).

SETTING THE LOOPER AVOID PLAIN FEED

If more or less looper avoid motion is required, remove cylinder side cover (A, fig 8) located at the lower front left side. For Plain feed use a screwdriver to loosen looper avoid link ball joint (B, fig 8) (for differential feed use TT-5 wrench to loosen looper avoid link screw C, fig 8). Moving ball joint down in the lever slot increases the amount of looper avoid motion, moving it up acts the reverse. Retighten ball joint B, Plain feed (screw C, differential feed) securely.

NOTE: Whenever looper avoid is changed looper clearance to needle must also be reset.

SETTING HEIGHT OF NEEDLE BAR

The height of the needle bar is correct when the top of the needle eye is 1/16" (1.6mm) below the underside of the looper, with the looper point even with the right side of the needle. To make adjustment loosen screw (A, Fig. 9) and move needle bar (B) as required to attain dimension.

NOTE: Care must be taken not to disturb the alignment of the needles when moving the needle bar either up or down.

SETTING THE FEED DOGS FOR PLAIN FEED

Assemble the main feed dog and throat plate. Main feed dog (A, Fig. 11) at its highest position, should be set to project above the throat plate, slightly more than the depth of its teeth for Style 35800BQWG. The feed dog mounting screw (B) and front support screw (C) should be set to maintain this setting.

The feed should be set so there is equal clearance between the front of the feed dog and the front of the feed slot in the throat plate when the feed dog is at its most forward travel. The same amount of clearance should be between the back of the feed dog and the back of the feed slot in the throat plate when the feed dog is at its most rearward travel. To attain this setting loosen screws (A and B, Fig. 10) and remove plug screw (D). Using a screw driver turn eccentric pin (C) clockwise or counterclockwise to obtain proper setting. Tighten screws (A and B), reinstall plug screw (D).

SETTING THE FEED DOGS FOR DIFFERENTIAL FEED

Before assembling the main and differential feed dogs, set the feed bar eccentric pin (A, Fig. 10A) located in the left side near center of cylinder, so that the slot in the head is in a horizontal position for the 35800BWDNG, BLWG style machines and turned counter clockwise to an approximate 45° for the 35800BWWG style of machine. The pin can be used to slightly tilt both feed dogs if necessary. The feed bar pin is retained in position by set screw (B). Assemble differential feed dog (A, Fig. 11A), main feed dog (B) and throat plate. Both the main and differential feed dogs can be individually adjusted to height. Main feed dog (B) at its highest position, should be set to project above the throat plate, the depth of its teeth. If adjustment is necessary loosen screw (D) and move feed dog (B) up or down to attain correct setting. Feed dog support (C) should support front of feed dog.

NOTE: If eccentric pin (A, Fig. 10A) is used to tilt the feed dogs, make sure that the looper does not interfere with the rear needle guard and that the needle guard does not pinch the needle loops on the back side of the needles.

SETTING THE FEED DOGS FOR DIFFERENTIAL FEED (CONT.)

If adjustment is necessary loosen screw (E, Fig. 11A) in feed dog support (C) and move as required. Retighten screw (E). The differential feed dog (A) may then be leveled with main feed dog (B). If adjustment is necessary loosen screw (F) and move feed dog up or down as required. Retighten screw (F).

NOTE: Should the main feed dog require repositioning due to contact with the throat plate in its forward or rearward travel, loosen set screw (C, Fig. 10A) in main feed bar driving link (D), rotate main feed bar eccentric driving stud (E) as required. Driving stud (E) has a thin hexagon head with cutouts on two of the flats allowing movement by tapping with a sharp pointed tool, when wrench 21388AZ is not available. Whenever the main feed bar eccentric driving stud position has been changed, recheck rear needle guard setting, adjustment may be required. Retighten set screw (C). Position main feed dog support (C, Fig. 11A) flush against bottom of main feed dog (B), tighten support screw (E) securely.

CHANGING STITCH LENGTH

When change in stitch length is required, remove large plug screw (A, Fig. 12). Loosen feed rocker driving linkscrew (B) in lever (C). Moving the feed rocker driving link up in the lever slot lengthens the stitch, moving it down, shortens the stitch. Retighten link screw (B) securely and replace plug screw (A).

NOTE: If plug screw (A) is replaced with a new plug screw, it should be sealed with a silicone seal.

Any stitch length change, requires resetting the needle guard.

CAUTION: When making stitch length adjustment do not exceed maximum recommended stitch length due to possible part damage.

SETTING REAR NEEDLE GUARD

Set the rear needle guard (A, Fig. 13) horizontally so that it barely contacts needles (B) when at its extreme forward position. If adjustment is necessary loosen screw (E) and move guard front to back as required. It should be set vertically as low as possible, yet have its guarding surface in contact with the needles until the points of the loopers (C), moving to the right, are even with the right side of the needles. If adjustment is necessary loosen screw (F) and move guard and holder up or down as required.

CAUTION: If stitch length is changed, needle guard must be reset.

NOTE: When installing the needle it should be parallel with the eye in line of feed. If adjustment is necessary, loosen screw (N, Fig. 15) in needle head and rotate needle to attain adjustment (D, Fig. 13).

Assembly of Roller to Roller Yoke:

Assemble driven gear (A, Fig.16) through feed roller frame (B). Place woodruff key (C) into slot of feed rollers shaft (D). Slide driven gear (E) on to shaft (D), make sure key (C) goes into slot in gear (E). While holding feed roller frame (B) with steel roller (F) between the two frame lobs, slide feed roller shaft (D) and assembled components through frame. Make sure that shoulder of roller (F) is to the right. Align screw (G) (first in operating direction on roller) on the flat of shaft (E). At the same time thrust shoulder of shaft (D) against face of gear (E), make sure left edge of roller is against right (inside) face of left lob. Secure screw (G) on flat of shaft (D) and tighten screw (H).

UPPER FEED ROLLER ADJUSTMENT (CONT.)

When feed roller mechanism (C, Fig. 17) has been removed or replaced, .003" (0.08mm) minimum to .005" (0.13mm) maximum clearance should be maintained between roller and throat plate.

To Adjust Guiding System for Roller:

Loosen two screws (A). Using shim(s) adjust feed roller mechanism (C) so that the roller is .003" (0.08mm) to .005" (0.13mm) above throat plate. Slide rear guide finger (B) down so that it sits on top of rear guide support block (D). Check to make sure roller is parallel to throat plate slots. Tighten two screws (A) to secure feed roller mechanism in place.

Setting Pressure for Feed Roller:

Regulate the pressure on the feed roller so that it exerts only enough pressure on the fabric to feed the work uniformly. Turning roller presser spring regulator (H, Fig. 17) clockwise to increase or counterclockwise to decrease the pressure.

Setting of Feed Roller:

Guide finger for roller should be set so that entire roller mechanism has free movement up and down with no left to right movement. With roller properly aligned, the edge of roller should be parallel with feed slots in throat plate.

Guide plates (F) must be thrusted against guide finger (B) to secure feed roller mechanism (C). Thrust guide plates (F) against guide finger (B) with equal pressure. Tighten four screws (E) to hold plates in place.

THREAD TENSION AND RELEASE

The thread tension release is set correctly when it begins to function at the point when the upper feed roller begins to rise. When adjustment is necessary, loosen screw (B, Fig. 18) in lifter lever (C). Facing the tension release shaft (A) from the right end of the machine, insert screwdriver in slot in shaft (A). Turn the screwdriver clockwise to raise pins (D) or counterclockwise to lower pins. Retighten screw (B).

DIFFERENTIAL CONTROL

The amount of differential is controlled by lever (A, Fig. 19). The adjusting plate is numbered from 1 to 9. When the lever is set from numbers 1 to 4 reverse differential or stretching occurs. The numbers from 4 to 5 produce equal feed stitching while numbers 5 to 9 produce a gathering stitch. Screws (B) can be set to limit the movement of lever (A) or lock lever in one position. If top ply of material is coming out long, move lever toward operator, if top ply is short, move lever away from operator, as required.
