OILING

These machines should be oiled twice daily, before the morning and afternoon starts. Use a good grade of straight mineral oil of a Saybolt viscosity of 200 to 250 seconds at 100° Fahrenheit.

Most of the oiling places on these machines are readily identifiable because of the fact they are painted red. However, reference to the oiling diagram, Fig. 1, on Page 6, will be beneficial.

Please note that it will be necessary to remove head cover, cylinder end cover, and to tilt the machine back from the sub-base to reach some of the oiling places.

Referring to the oiling diagram, it will be noted that there are two lubrication points marked "A", and one marked "B".

The two points "A" are for the needle bearings on the upper main shaft, and are lubricated with a light grease about once a week. Tubes of grease may be ordered from Union Special under part No. 61-81.

Point "B" on the diagram refers to the cover over the hook driving gears, which are lubricated with a standard wheel bearing grease. Periodically, the cover should be removed and the grease replenished, if necessary.

SPEED

The recommended speed of these machines is 1500 R.P.M.

NEEDLES

Use only genuine Union Special Lewis needles. They are stamped with the word "Lewis" on the shank.

Needles for the Lewis Class 16 machines are available in all the required sizes in both uniform blade and ball eye.

Immediately discard any needle which may have a hooked or blunt point.

To have needle orders promptly and accurately filled, an empty container, a sample needle, or the type number should be forwarded. A complete order would read: "100 Needles, Type 129-133 1/2".

THREADING

Thread machines in accordance with threading diagram, Fig. 2, on Page 7. Please note that Styles 16-100, 16-100 H, 16-290, 16-400, 16-410 B, 16-410 T, 16-420 are threaded in accordance with the upper diagram, and Styles 16-260 and 16-265 with the lower. The diagram for Styles 16-260 and 16-265 is not pictorially accurate in that these two Styles are left hand machines, but for the purpose of tracing the threading, it will suffice.

ADJUSTING

REMOVING EXCESS PLAY IN CONNECTING RODS

Access to the connecting rod adjusting screws is through the opening in the top of the arm (Fig. 3). Remove arm cover plate, and tighten screw (A) in plunger drive connecting rod (B) until machine begins to bind while handwheel is being turned in operating direction. Then, loosen screw until machine again turns freely. Repeat same operation with feed elevating connecting rod (C) and feed driving connecting rod (D). Replace arm cover.

TIMING NEEDLE TO THE PLUNGER

The needle should be timed so that, on its downward stroke, it is 1/4 inch from the center of the plunger when the plunger reaches its highest point of travel. To accomplish this adjustment, loosen the screws (A, Fig. 4) in the driving gear (B) and remove the gear. Turn the handwheel in operating direction until the plunger just reaches its highest position. Do not continue to turn the handwheel after the plunger has first reached its highest position. Now, turn the needle crank (C) in the direction of its arrow until the needle, when on its downstroke, is within approximately 1/4 inch of the center of the plunger.

Then, replace driving gear (B) on the main shaft, line up the spot screw with the spot on the shaft, and re-tighten screws (A).

TIMING THE HOOK

Turn the handwheel in operating direction until the needle has reached the forward end of its travel and returned 3/32 inch. At this position, the point of the hook should be over the center of the needle. To obtain this adjustment, remove hook gear cover on the back of the head to expose the gears (Fig. 5). Loosen screws (A) in gear (B) and turn gear (C) in the required direction to position the point of the hook over the center of the needle. Re-tighten screws (A).

SETTING HEIGHT OF HOOK

The point of the hook should be set as close to the needle as possible without striking it. To make this adjustment, loosen screws (D and E, Fig. 5) and remove gear (C), exposing hook bushing flange (B, Fig. 6). Loosen screw (A) and rotate the hook bushing flange (B) in the required direction to position the hook point as described above. If the hook bushing flange cannot be turned far enough to secure this setting, remove screw (A) and place it in the alternate hole in the casting to secure more adjustment. Re-tighten screw (A).

Turn handwheel in operating direction until timing mark (F, Fig. 5) on gear (B) appears over the hook shaft. Replace gear (C) so that spot screw (D) aligns with "V" groove (G) in hook shaft and turn screw down lightly. Turn gear (C) and hook shaft until timing line (H) on gear (C) aligns with timing line (F) on gear (B).

Re-engage gears (B and C) and tighten screws (D and E) making sure that all end play is removed. Replace gear cover on back of head.

TIMING THE BOBBIN CASE RELEASE

Turn the handwheel in operating direction until the needle carrier (A, Fig. 7) reaches the highest point of its travel. (Note: The photograph (Fig. 7) does not show the needle carrier in this position, so that the bobbin case and bobbin case release can be seen.)

At this point, the angular projection on bobbin case release lever (E) should be bearing against the extension of the bobbin case release (C) so that there is a clearance of about 1/32 inch between bobbin case (B) and the point of the release (C).

To obtain this adjustment, loosen nut (D) and move bobbin case release lever (E) up or down as required. Re-tighten nut (D).

ADJUSTING THE LOOPER AND SPREADER

When properly adjusted, the points of the looper and spreader must move freely without any interference with the presser foot, feed plate, bobbin case retainer, needle, or needle carrier.

Fig. 6

ADJUSTING THE LOOPER AND SPREADER (Continued)

To adjust the looper and spreader mechanism to the right or left, loosen set screws (A and B, Fig. 8) and move the whole mechanism in the required direction. Re-tighten set screw (A), and turn handwheel slowly in operating direction to remove any binds, and then, re-tighten set screw (B).

A B C 1 32 D E

Fig. 7

To adjust the looper and spreader mechanism up or down, loosen screw (C) and move the mechanism in the required direction by pulling out or pushing in on the knurled stud (D). Re-tighten screw (C).

To adjust the looper and spreader mechanism in or out, loosen screw (B) and turn the eccentric bushing (E) in the required direction by placing a screw driver in one of the two oil holes in the bushing and turning. Turn handwheel slowly in operating direction to remove any binds that may appear. Re-tighten screw (B).

A combination of all the preceding adjustments may be necessary to properly adjust the looper and spreader mechanism. It also may be necessary to remove any play or bind that may have developed between gears (F and G) as a result of these adjustments. This can be checked by moving stud (D) back and forth when the looper and spreader mechanism is at its lowest point. At this position, very little play should be observed. To remove any bind or excess play, loosen set screw (A), and turn eccentric bushing (H) in the required direction by placing a screw driver in one of the two notches in the bushing. Turn handwheel slowly in operating direction to remove any binds and re-tighten screw (A).

Turn handwheel slowly in operating direction to check the preceding adjustments to make sure that there is no interference between the looper and spreader mechanism and other parts, and repeat adjustments if necessary.

SETTING THE FEED PLATE HEIGHT AND PRESSURE

Turn handwheel in operating direction until the feed point has reached the lowest point of its travel. At this position, there should be no play between the feed plate and the presser foot.

To make this adjustment, loosen screw (A, Fig. 9) and, with the right hand, hold the feed plate against the presser foot. Then, by holding the feed link (B) with the left hand, push down the feed point until there is 1/32 inch clearance between the block (C) and the plunger bearing block (D). Then, re-tighten screw (A).

Turn handwheel in operating direction until the feed point reaches its highest position, and check to see that the feed point is in the center of the slots in the feed plate. If the feed point is not in proper alignment, loosen screw (A) and turn the feed plate to align the feed point in the slots. Re-tighten screw (A).

The feed plate pressure is adjusted at the factory. If it becomes necessary to change the pressure, turn the knurled screw (A, Fig. 11) clockwise for more pressure and counterclockwise for less.

SETTING THE FEED POINT HEIGHT

Turn handwheel in operating direction until the feed point reaches its highest position and the feed plate reaches its lowest position. At this point, there should be 1/8 inch space between the top of the feed plate and the bottom of the presser foot (Fig. 10). To obtain this adjustment, loosen the machine base locking screw (A, Fig. 12) and lay the machine on its side. Then, loosen screw (B, Fig. 11) and hold link (B, Fig. 10) so that the feed point is pressed up against the bottom of the presser foot. Turn handwheel in operating direction until the feed point reaches its most forward position, and re-tighten screw (B, Fig. 11).

SETTING FEED POINT IN LINE OF FEED

Turn the handwheel in operating direction until the feed point first touches the presser foot. At this point, the

Fig. 10

front edge of the feed point should be aligned with the front edge of the knurling on the feed plate. To make this adjustment, loosen screw (C, Fig. 11), and, by means of link (B, Fig. 10), move the feed point forward or backward as required. Re-tighten screw (C, Fig. 11). If, in this adjustment, the feed point has to be moved an appreciable distance, repeat the adjustment "Setting The Feed Point Height" in the previous instruction.

The height of the plunger is adjusted by turning knob (B, Fig. 12) clockwise to raise the plunger and counterclockwise to lower it. To provide for the maximum plunger adjustment, there should be 1/32 inch clearance between plunger crank (A, Fig. 13) and plunger block (B) when the adjusting knob (B, Fig. 12) is turned clockwise as far as it will go. Note that there are pins which stop the knob

(B, Fig. 12) after each complete revolution. The knob may be pulled out toward the operator to lift it over the stop. The knob can make three complete revolutions. To make the 1/32 inch adjustment, turn the knob clockwise as far as it will go. Loosen

lock nut (D, Fig. 11) and turn screw (E) in the required direction. Re-tighten nut (D).

ADJUSTING AUTOMATIC PLUNGER

Some machines in this class are equipped with an automatic plunger to insure a uniform depth of needle penetration when felling across parts of a garment where there is considerable variation in thickness.

Below the regular or work presenting plunger, which is in the plunger barrel (A, Fig. 14), is the lower plunger (B).

Fig. 11

ADJUSTING AUTOMATIC PLUNGER (Continued)

To adjust the lower plunger in relation to the upper or work presenting plunger, back off the crown adjusting screw (A, Fig. 20) on the presser foot. Loosen knurled adjusting nut (C, Fig. 14) so that the lower plunger (B) does not contact the upper plunger at any time. Set the penetration knob (B, Fig. 12) so that the work presenting plunger is high enough to cause the needle to penetrate the material to the proper depth. Then, turn the penetration knob about 2 or 3 notches higher. With the upper or work presenting plunger at low position, turn the knurled adjusting nut (C, Fig. 14) until the distance between the lower nut (D), on the upper plunger, and the lower plunger (B) is 1/32 inch.

B A

Fig. 12

Turn the crown screw(A, Fig. 20) down, and test sew to see that, when a pocket or pleat is crossed, the amount of needle penetration remains the same.

INSERTING BOBBIN IN HOOK

Turn the handwheel in the operating direction until the needle carrier has reached its highest position and returned about 1/4 inch.

Open the bobbin case latch (A, Fig. 15), and insert bobbin (B) so that the thread will come off the bottom of the bobbin in the direction of the bobbin case tension spring (C) and through the notch (D) in the bobbin case. Close bobbin case latch. The tension on the bobbin thread is controlled by turning screw (E) in the required direction. For easier access to this screw, have the needle carrier at high position.

SETTING THE STITCH LENGTH

This adjustment is made through the access hole in the top of the arm (Fig. 16). Remove top cover and turn handwheel in operating direction until lock screw (A) and adjusting screw (B) are in view. Loosen lock screw (A) and turn adjusting screw (B) in the required direction. Turning the adjusting screw clockwise shortens the stitch and counterclockwise lengthens it. Re-tighten lock screw (A) and replace top cover.

THREAD CONTROL

Make sure the machine is threaded in accordance with threading diagram (Fig. 2, Page 7), and sew machine under power to check stitch.

THREAD CONTROL (Continued)

If the hook is not catching the needle thread as a result of the needle not throwing up a large enough loop, then the needle carrier should be adjusted. To make this adjustment, turn handwheel in operating direction until the needle carrier is in its most forward position, and, with a wrench, loosen nut (A, Fig. 17) and turn needle carrier driving stud in the required direction. Access to this stud is through the hole in the head casting (B). If the hook is still not catching the needle thread, re-time the hook as previously instructed.

If the needle thread snaps as it passes over the top of the bobbin case, it is an indication that either the tension on the thread controller spring (C) is too great or that the hook is a trifle slow or both. If the tension on the thread controller spring (C) is not great enough, the thread will not come off the hook fast enough with the result that hook will pick up the thread a second time, causing the machine to

Fig. 16

break thread. To make this adjustment, turn thread controller staff (D) in the required direction.

Thread breakage may also result if the needle thread tension is set either too loose or too tight. The tension on the needle thread is regulated by turning thumb nut (E) to the right or left as required. This tension should be set sufficiently tight to produce a firm stitch. Do not, however, make this adjustment too tight, because the thread will draw the goods and will leave impressions or dimples on the face of the garment.

If it is found that the looper (B, Fig. 18) and spreader (A) are skipping stitches, an adjustment can be made by loosening lock nut (C) and turning the eccentric adjusting stud (D) in the required direction. If further adjustment is required, repeat looper and spreader adjustment in previous instruction.

REMOVING LOOPER AND SPREADER MECHANISM

A straight two thread stitch, instead of an overcast stitch, may be formed by removing the looper and spreader mechanism. This may be done by removing screw (A, Fig. 19) and loosening screw (B), and then removing stud (C). The looper and spreader mechanism can now be removed.

NOTE: The removal of the looper and spreader mechanism is not recommended on 15 ^o machines.

ADJUSTING WIDTH OF BITE

The width of the bite taken by the needle depends on several factors, the most important being the angle of the machine. Thus, a 45^ machine will produce a wider bite than a 15^ machine, other conditions being equal. The width of bite is also dependent on the depth to which the needle penetrates the material as well as the shape of the top of the plunger.

ADJUSTING WIDTH OF BITE (Continued)

A B C D

Fig. 18

For any given set of these conditions, the width of the bite may be adjusted by moving the edge guide (B, Fig. 20) to the right or left by loosening screw (C). By moving the guide to the left, a wider bite will result, to right acts the reverse.

REMOVING AND REPLACING PRESSER FOOT

Turn handwheel in operating direction until the plunger is in its lowest position, and remove the two screws which hold the presser foot to the head casting. Press knee lifter to release the pressure on the foot and remove foot.

To replace the foot, keep the plunger at its lowest position. Press the knee lifter and place the foot in position on the frame. Replace and tighten the two screws that hold the foot on the head casting, being sure to see that the groove in the bobbin case (F, Fig. 15) fits over the projection

A B C

Fig. 19

in the bobbin case retainer (D, Fig. 20) to hold the bobbin in position.

Check to see that the needle guide (E) lines up exactly with the needle. If it does not, loosen screw (F) and turn handwheel slowly in operating direction until the needle passes over the needle guide. This will allow the needle to center the needle guide. Re-tightenscrew (F). The needle should now ride in the center of the groove in the guide. This adjustment is especially important when felling light materials in order to obtain accuracy and consistency of penetration.

ORDERING REPAIR PARTS

ILLUSTRATIONS

This catalog 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 parts 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 that part in the illustration. 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. Example:

50	4115-72-3	Plunger Bearing Block, complete, for Styles 16-100, 16-100 H, 16-400, 16-410 B, 16-410 T, 16-420	1
51	4121-3	Plunger Frame and Barrel Assembly	1
52	1306 L	Screw	1
53	16-352	Bushing	1

It will be noted in the above example that the plunger bearing block is not listed. The reason is that the replacement of this part individually is not recommended, so the complete sub-assembly should be ordered.

At the back of the book will be found a numerical index of all the parts shown in this book. This will facilitate locating the illustration and description when only the part number is known.
