FOREWORD

This technical manual has been prepared to guide you in the maintenance of your new UNION SPECIAL machine. Careful attention to the instructions for operating and adjusting these machines will enable you to maintain the superior performance and reliability designed and built into every UNION SPECIAL machine.

The Adjusting Instructions portion of this manual explains in detail the proper setting for each of the components related to forming the stitch and completing the functions of the machine. The text of the Adjustments is divided into two sections - Check and Procedure. The Check depicts conditions when the parts are adjusted correctly. The Procedure is given to explain the proper steps to be taken in the event adjustments are required. Figures are used to illustrate the adjustments using reference letters to point out specific items discussed.

Adjustments are presented in sequence so that a logical progression is accomplished. Some adjustments performed out of sequence may have an adverse effect on the function of other related parts.

Implementation of preventative maintenance procedures can bring about significant improvements in operator productivity by avoiding costly equipment breakdowns. Whenever it becomes necessary to make repairs or replace parts on your machine, be sure to insist on genuine UNION SPECIAL Repair Parts. These parts are designed specifically for your machine and manufactured with utmost precision to assure long lasting service.

To simplify identification of repair parts, the mechanisms are illustrated by exploded views.

Replace rear needle guard (B) using screw (C) with front edge of guard centered in slot of knife holder as shown. Temporarily tighten screw (C) to hold guard in position, yet allowing guard to be adjusted.

Rotate handwheel in operating direction so lower looper (D) travels from the extreme left into scarf of needle(s). Set guarding surface of guard (B) to touch but NOT deflect needle(s) while also setting guard as low as possible to prevent it from interfering with needle thread as loop is being formed to rear of needle(s), then tighten screw (C) securely.

Guard must NOT interfere with lower knife holder movement or contact lower looper at any point of travel.

FRONT NEEDLE GUARD

Replace front needle guard (E, Fig. 8) using screw (F). Temporarily tighten screw (F) to hold guard in position, yet allowing guard to be adjusted.

Rotate handwheel in operating direction until needle(s) is at lowest position, then set guarding surface of guard (E) to needle(s) with minimum clearance - approximately .004 inch (.10mm) and tighten screw (F) securely. Check adjustment to ensure needle(s) is NOT being pinched between front and rear needle guards.

Rotate handwheel in operating direction and closely observe the path of upper looper/spreader as it travels from the extreme right and approaches the lower looper as shown in Fig. 9. The point of upper looper/spreader MUST pass the notch in head of lower looper with minimum clearance and pass under lower looper thread.

Again rotate the handwheel until the upper looper/spreader is positioned to extreme left as shown in Fig. 10. At this time, point of upper looper/spreader MUST be in position so the descending needle or right needle will pass to the right of the upper looper/spreader thread, which extends from the eye of the looper to the previously formed stitch. The upper looper/spreader must NOT contact the lower looper or needle(s) at any point of travel.

2. With upper looper/spreader positioned at the right end of travel, loosen screw (C) and rotate holder (B) as required to set shank slightly back of vertical as shown in Fig. 12, then temporarily tighten screw (C, Fig. 11).

3. Rotate handwheel in operating direction bringing the upper looper/spreader into the lower looper, See Fig. 9. Loosen screw (A, Fig. 11) and set the point of upper looper/spreader to enter the notched area behind head of lower looper with minimum clearance.

4. Again rotate handwheel in operating direction until the upper looper/spreader is at the extreme left end of travel. Loosen screw (C, Fig. 11) and rotate holder as required to set point of looper/spreader to dimension "E" Fig. 13 from top of throat plate.

5. With upper looper/spreader still positioned at the left end of travel, it may be necessary to adjust the holder in or out of its shaft to set point of looper/spreader to dimension "F" Fig. 13 to the left of needle and/or right needle centerline. Rotate handwheel to position upper looper/spreader to the right end of travel, then tighten screw (C, Fig. 11) and screw (A) securely.

6. If the needle(s) is being deflected by the upper looper/spreader, clearance to the needle(s) can be increased by reducing the length of shank above holder, See Step 1. It will then be necessary to slightly reduce the angle back of vertical, See Step 2. Also reset upper looper/spreader to lower looper, See Step 3. Reversing this procedure will position the upper looper/spreader closer to the needle(s).

PRESSER FOOT LIFT

Check:

Lift presser foot to highest position and rotate handwheel in operating direction. Upper looper must not contact presser foot at any point of travel.

Procedure:

Loosen locknut (H, Fig. 17) and adjust stop screw (J) so presser foot will not interfere with upper looper, then tighten locknut (H).

Loosen locknut (K) and set stop screw (F) on upper end of lifter lever arm so there is approximately 1/16 inch (1.6mm) free motion in lifter lever before presser foot starts to rise, then tighten locknut (K).

PRESSER FOOT PRESSURE

Check:

Sufficient pressure must be maintained to feed work uniformly. Excessive spring pressure will cause feeds and presser foot to wear prematurely when chaining.

Procedure:

Rotate handwheel in operating direction until both main and differential feeds are positioned below throat plate. Loosen locknut (L, Fig. 17) and turn adjusting screw (M) clockwise for more pressure or counterclockwise for less pressure, then tighten locknut (L).

NOTE: Adjusting screw (M) will effect the function of pressure release bushing (A). Plunger must clear presser arm when pressure release bushing is unlocked. When release bushing is locked in position, presser foot must be held firmly against throat plate. If these conditions do not exist the following adjustment must be made.

Lock presser foot in position with pressure release bushing (A); loosen capnut (N) and adjust nut (P) up or down so its under surface is 1/16 inch (1.6mm) above screw (M) as shown in Fig. 17. Hold nut (P) in position and tighten capnut (N).

SETTING THE HEMMING GUIDE SUPPORT BRACKET (STYLES 395-20 and -21)

Loosen lock screw (A, Fig. 18), then proceed as follows:

Assemble the hemming guide support bracket onto the lower knife support bracket by means of screw (B, Fig. 18). With the knurled adjusting screw (C), set the edge guide (D) so that the left side of its tip is even with and parallel to the right side of the right feed slot in the throat plate.

When the edge guide tip is in this position, the front or leading edge should be slightly to the right of parallel. This adjustment can be made by positioning the stop screw (A, Fig. 19) located towards the front of the hinge block and edge guide support bracket (E, Fig. 18).

Under normal conditions, the edge guide is spring loaded to compensate for the differences in the material thickness. The amount of movement and the pressure applied to the edge guide tip can be set by removing lock screw (B, Fig. 19) and adjusting the screw which presses against the spring and pin, located in the hinge block and edge guide support bracket (E, Fig. 18). Replace lock screw and tighten securely.

Technical diagram of a mechanical device with labeled parts A, B, C, D and directional arrows indicating movement or assembly.

Fig. 19

If movement of the edge guide is not required, then remove lock screw (B, Fig. 19), set screw and spring; then replace set screw and lock screw. Be sure set screw is tightened against pin and lock screw is tightened against set screw.

FINAL ADJUSTMENT OF HEMMING GUIDE (STYLES 395-20 and -21)

Adjust the edge guide (D, Fig. 18) by turning the knurled adjusting screw (C) so that the stitches are located in the folded edge, yet do not show on the face of the fabric. At this point re-tighten screw (A, Fig. 18) securely.

Adjust the overhanging guide (F, Fig. 18) so that the space between its guiding edge and the edge guide (D) corresponds with the thickness of the material to be hemmed. Loosen set screw (C, Fig. 19) and holding screw (D), now move the hinge block (E) to obtain the proper distance between the edge guide and the overhanging guide. Re-tighten screws (C) and (D). Remove lock screw (F) and adjust stop screw that is in front of lock screw, so that the tip of the overhanging guide is located at the center of the edge guide vertically. Replace lock screw (F) and tighten against stop screw.

SETTING STITCH LENGTH

The actual stitch length produced is usually measured as the number of stitches sewn per inch of seam. This is determined by the distance feeds travel with their teeth protruding above the throat plate.

SETTING STITCH LENGTH (Continued)

Class 395 machines are fitted with a feed system having two separate feed dogs - MAIN (rear) and DIFFERENTIAL (front).

The resulting stitch length is determined to a great extent by travel of the main feed. The differential feed travel can be used to gather or stretch the fabric prior to being stitched.

Length of stitch is determined by the combination of feed eccentricis used. Outer (left) eccentric (A, Fig. 20) actuates main (rear) feed dog; while the inner (right) eccentric (B) actuates the differential (front) feed dog.

In assembling feed eccentrics, be sure hubs are facing each other. Be careful not to damage shaft or key. Tighten nut (C) securely.

Technical diagram of a mechanical assembly with labeled parts A through F, showing components like bolts and gears.

Fig. 20

To change feed eccentric, remove nut (C) and washer (D) from end of shaft (E). Turn handwheel in operating direction until key slot in eccentric is toward front. Using hooked eccentric extractor (F), supplied with machine, reach behind eccentric as shown and withdraw eccentric. It may be necessary to move handwheel back and forth slightly during extraction.

NEEDLE THREAD CONTROL

Check:

The needle thread is controlled by the needle thread eyelet (A, Fig. 21) and the needle thread cam pull-off (B). The needle thread eyelet is set so the securing screw is centered in the screw slot front to back. Raise or lower the eyelet to have the needle thread barely touch the needle thread cam pull-off when the needle carrier is in its lowest position. Moving the eyelet up and back increases the needle thread in the stitch, moving the eyelet down and forward acts in the reverse.

Fig. 21

Procedure:

To adjust needle thread control, loosen screw (C) and position thread eyelet (A) as described in check. Hold eyelet in position and tighten screw (C).

LOOPER THREAD PULL-OFF

Check:

Clearance between looper thread pull-off (D, Fig. 21) and needle thread cam pull-off (B) should be only enough to ensure proper take-up of looper thread as shown in Fig. 21.

LOOPER THREAD PULL-OFF (Continued)

Procedure:

Loosen screws (E) and rotate looper thread pull-off lever (F) front to back on needle driving shaft until proper clearance is obtained. Before tightening screws (E) be sure to take up all end play in needle drive shaft.

LOOPER THREAD CONTROL

Check:

When a normal amount of looper thread is drawn, upper and lower looper threads will be a little slack when needle(s) is at highest position (lower looper thread only for Styles 395-20 and -21).

The auxiliary upper looper thread guide (E, Fig. 22) should be centered in its adjusting slot and set slightly above a horizontal position.

Labeled mechanical assembly diagram with components A through G marked for identification

Fig. 22

Procedure:

Loosen screw (A, Fig. 22). Center lower loop-er thread eyelet (B) in its adjusting slot and set eyelet in a horizontal position. Hold eyelet (B) in position and tighten screw (A).

On all Styles except 395-20 and -21; loosen screw (C). Center upper looper thread eyelet (D) in its adjusting slot and set eyelet so it rests on the top surface of lower looper thread eyelet and back of lower looper thread eyelet eye.

Center auxiliary upper looper thread guide (E) in its adjusting slot and set guide so it is slightly above a horizontal position. Hold

lower looper thread eyelet (D) and auxiliary upper looper thread guide (E) in position and tighten screw (C).

To set frame lower looper thread guide (F) loosen screw (G) and move lower looper to its extreme left end of travel and position the guide so the looper thread is held in a straight line to the lower looper. Tighten screw (G).

NOTE: Moving eyelets (B and D) to the rear increases the amount of looper thread in the system and moving them forward reduces the amount of thread in the system.

POSITIONING THE PURL

The following instructions are for machines producing three thread stitch type 504.

If the needle thread loop is NOT being set properly as shown in Fig. 23, excessive seam grinning would result. Thread control adjustments which should be checked to correct this condition include:

• Lower looper thread tension too tight.
• Needle thread eyelet too high.
• Lower looper thread eyelet too far forward.
• Needle thread tension too loose.

If the purl is NOT being formed on the edge of the fabric as shown in Fig. 24, an unbalance between the looper threads is indicated, and improper coverage of the seamed edge would occur. If the purl is being pulled under the edge, check the following thread control adjustments:

• Lower looper thread too tight.
• Lower looper thread eyelet too far forward.
• Upper looper thread eyelet too far to the rear.
• Upper looper thread tension too loose.

If the purl is being pulled over the edge as shown in Fig. 25, check the following thread control adjustments:

• Upper looper thread tension too tight.
• Upper looper thread eyelet too far forward.
• Lower looper thread eyelet too far to the rear.
• Lower looper thread tension too loose.

THREAD TENSIONS

Thread tension is regulated by the tension assemblies. Turning tension nuts clockwise increases tension applied to thread, counterclockwise reduces tension. Normally, tension on the threads should be only enough to produce a balanced stitch.

"AIR-KLIPP® VACUUM CHAIN CUTTER

1. If adjustment to the "AIR-KLIPP" is necessary; remove cloth plate and throat plate.
2. Remove "AIR-KLIPP" assembly from the machine by removing screws (A, Fig. 26), washer plate (B) and screw (C).

With "AIR-KLIPP" assembly out of machine; position movable knife (D) to its extreme right. Loosen screws (E) and press air tube (F) and base (G) together applying only enough pressure on movable knife to ensure proper cutting maintaining a slight shear angle, then tighten screws (E).

When the movable knife (A, Fig. 26A) travels from extreme left to the right; its cutting edge must be even with the cutting edge of stationary knife-Ref. Point B.

To adjust movable knife (A), loosen screw (C) and position knife front to back as required. Hold knife in position and tighten screw (C). Check, if movable knife (A) is adjusted properly it will cut a single strand of thread when manually moving knife left to right.

1. Re-assemble "AIR-KLIPP" assembly to the machine, securing knife driving link with screw (C, Fig. 26) and base with washer plate (B) and screws (A).

With "AIR-KLIPP" assembly in position, temporarily replace throat plate and check for a 1/64 inch (.4mm) clearance between front edge of air tube (D, Fig. 26A) and rear edge of throat plate (E), as shown. If a clearance adjustment is necessary, loosen screws (E, Fig. 26) and adjust the air tube (F) front to back on "AIR-KLIPP" base as required. Re-adjust movable knife pressure as outlined in STEP 2, then tighten screws (E).

Before tightening mounting screws be sure the right side of "AIR-KLIPP®" base is set flush against the main feed bar. Tighten screws (A and C).

Fig. 26A

NOTE: Main stitch length determines movable knife travel and must be set before making the following adjustment.

With main stitch length set and movable knife (A, Fig. 26A) positioned to its extreme right; loosen screw (C) and adjust movable knife left to right as required to extend no less than 1/64 inch, (.4mm) beyond the cutting edge of stationary knife as in Fig. 26A. Clearance must be maintained between the moving knife and the inner wall of air tube - Ref. Point F. Hold knife in position and tighten screw (C).

1. To adjust the air valve system, loosen screws (H, Fig. 26) and set collar (J) to permit actuator block (K) to just contact button of air valve - Ref. Point L, when button is fully extended, then tighten screws (H). When treadle is pressed to start sewing, the air valve must open before the clutch is engaged.

TO REMOVE CRANKSHAFT

Crankshaft can be withdrawn easier if these steps are followed:

1. Drain oil by removing plug screw located on back of machine near bottom edge of base.

2. Remove top and bottom covers of machine.

3. Remove feed eccentric nut (A, Fig. 27) and remove eccentric (B).

4. Remove key (C).

5. Remove three counterweights (D). Identify these counterweights so that they will be re-assembled in the proper places.

6. Remove screw (E) which holds crankshaft split bearing. This screw is reached through bottom of bed casting.

7. Remove caps of bearings on crankshaft at points F, G and H. When re-assembling bearing caps make sure they are in their original position. Trademarks are stamped on both halves of the caps and both trademarks should be on the same side of the bearings. Also, screws should be re-assembled in the same holes from which they were removed.

8. Loosen clamp nut (A, Fig. 28) which holds upper knife driving arm (B). Access to clamp nut is through top cover. Draw driving arm to the left until upper knife driving lever (C) and connecting rod (D) drop, allowing removal of bearing cap (E). This is located at bearing point (J, Fig. 27) on crankshaft. Observe same precautions while re-assembling cap as described in Step 7 above.

9. Remove screw (K, Fig. 27) which holds inner right crankshaft bearing. This screw is reached through bottom of bed casting.

Technical diagram of a mechanical assembly with labeled parts A, B, C, D, and E

Fig. 28

1. Remove screw (M); take off pulley cap (N).

2. Loosen two screws (P); remove pulley (R).

3. Remove three screws (S); take off bearing retaining plate (T); also, spacer collar (U) may be removed at this time.

4. Crankshaft may now be removed.

5. If necessary to replace ball bearing (V), it should be pressed off shaft on an arbor press. In replacing bearing it must be pressed on carefully until it seats against ground thrust washer (W).

6. Carefully observing reverse of the foregoing operations should simplify re-assembly of crankshaft. Checking exploded view drawings for location of various parts and constant testing for binds during re-assembly will also prove helpful.

TO REMOVE CRANKSHAFT (Continued)

1. Before re-assembling, thoroughly clean and dry top and bottom covers and gaskets. Before re-assembling bottom cover make sure that spring pressed oil wick which lubricates left crankshaft bearing is inserted in hole in casting and that it contacts shaft. The wick stands vertically on its spring against bottom cover. Coat oil drain plug with a sealing compound before re-assembling to prevent oil leakage.
