NEEDLES

Each UNION SPECIAL needle hasboth a typeand sizenumber. The typenumber

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

in thousandths of an inch, midway between shank and eye. Collectively, type and

size number represent the complete symbol, which is given on the label of ailneedlespackaged and sold by Union Special.

The standard recommended needle for the machines covered here is Type121 GBS. Below is the description and sizes available of the recommended needle,

Type No, Description and Sizes

121 GBS Round shank, round point, short, single groove, struck groove, spotted,ball point, chromium plated - available in sizes 065/025, 070/027,075/029, 080/032, 090/036, 100/040.

To have needle orders promptly and accurately filled, an empty package, asample needle, or the type and size number should be forwarded. Use descriptionon label. Acompleteorderwould read: “1000 eedles, Type 121 GBS, Size 080/032”.

Selection of proper needle size is determined by the size of thread used, Thread

should pass freely through needle eye in order to produce a good stitch formation,

Success in the operation of UNION SPECIAL machines can be secured only byuse of needles packaged under our brand name, j, which is backed by areputation for producing highest quality needles in materials and workmanship formore than three-quarters of a century.

THREADING AND OILING DIAGRAM

Thread machine as indicated, The looper threading has been enlarged for clarity, The RIGHT needle thread should be threaded through the uppermost thread tensioner and eyelet holes closest to the bed casting. The machine illustrated is a twoneedle machine, but the three needle machines are threaded in substantially thesame manner.

The oil has been drained from the machine before shipping, so the reservoirmust be filled before starting to operate, To fill machine with oil, remove plugscrew in top cover and add oil until the needle of oil gauge (A) is in gold band marked“FULL”, Use a straight mineral oil of a Saybolt viscosity of 90 to 125 seconds at100 Fahrenheit. Maintain oil level in “OPERATE” position and add oil when needleis in gold band marked “LOW”. The machine is automatically lubricated and nooiling other than keeping the main reservoir filled is necessary.

Excessive oil in the main reservoir may be drained at the plug screw (B).

(AUTTOP! Oil has been drained from the main reservoir before shipment, so the

reservoir must be filled to the proper level before beginning to operate. Run machineslowly for several minutes to distribute the oil to the various parts, Full speed

operation can then be expected without damage.

RECOMMENDEI) OIL

Oil may be drained from main reservoir byremoving plug screw (C, Fig. 2) located belowthe cloth plate at front of the machine,

NOTE: Looper avoid and feed lift eccentricsreceive oil thru the mainshaft, so when assembling be sure oil holes in the eccentric lines upwith oil holes in mainshaft when spot screw is

in timespot. See paragraph on “Changing Stitch Length” for repacking feed rocker

sealed greased bearings.

OIL GAUGE

The oil gauge is set at the factoryto show the proper oil level in the reservoir,

Should an adjustment become necessary, however, the following steps should befollowed:

1. Place the machine upright on a level table or bench,

2. Remove the oil reservoir plug screw (C, Fig. 2) and tip machine forward

to drain oil from the reservoir.

3, Make sure all oil is drained from main reservoir,

Use a straight mineral oil of0a Saybolt viscosity of 90 to 125 seconds at 100 Fahrenheit inthe main reservoir, This is equivalent to UnionSpecial specification No. 175 . Fill main reservoir at plug screw in upper crank chambercover (A, Fig. 2) and check oil level at gauge(B). Oil is at maximum level when needle is ingold band marked “Full”. Oil should be addedwhen needle is in gold band marked “Low”.

CAUTION! It is important that these machinesnot be over filled.

It is recommended that a new machine, orone that has been out of service for an extendedperiod of time, be lubricated as follows: Removethe head cover, clean out lint and directly oil theneedle bar link and the needle bar. Replace headcover as no further hand oiling will be required.Run machine slowly for several minutes todistribute oil to the various parts.

Check the synchronization of the looper and needle motions, using gauge No,21227 H as follows:

insert the pin (A, 1’ig, 5) in the looper rocker,Place the gauge plate (13) on the throat plate seat using

_______

the throat plate screws for attaching. Place the shank (C)of the indicator (D) in the needle thread take-up wirehole, Turn the handwheel in operating direction untilthe pin (A) contacts the edge of gauge plate (B) and setthe indicator (ID) so that the left end of the pointer (E)rests on top of the needle bar and the right end of thepointer aligns with b0I, Tighten the set screw to secure the indicator in this position, Turn the handwheelin the reverse direction until pin (A) again contactsgauge plate (B), If the motions are in synchronization,the pointer of the indicator will return to the samereading, A variation of one graduation on the scale isallowable. If the reading is higher on the scale whenthe handwheel is turned in the operating direction, thelooper drive lever shaft will have to be moved to therear, If the reading is lower, the looper drive levershaft will have to be moved to the front,

NOTE: If gauge No, 21227 R is not available, synchronization may be checked as follows:

Insert the looper in the looper rocker and turn thehandwheel in operating direction until the point of thelooper, moving to the left, is even with the left side ofthe right needle. Note the height of the eye of the needle with respect to the looper point, then turnthe hand- Fi 5wheel in reverse direction until the looper point againmoves to the left and is even with the left side of theright needle, If the motions synchronize, the height of the eye of the needle with respect to the looper point will be the same, A variation of . 005 inch (.13 mm) is

allowable, If the distance from the eye of the needleto the point of the looper is greatest when the hand-wheel is turned in the operating direction, move thelooper drive shaft synchronizing stud (A, Fig, 6)to the rear, Moving it in the opposite direction actsthe reverse,

To move the looper drive shaft synchronizingstud to the rear (away from operator), loosen theclamp screw (B, Fig, 6) in the looper drive lever(C), A light tap with a small hammer, directly onthe stud, is all that is required, To move stud forward (towards operator), remove the cloth plate,throat plate support, oil reservoir top cover andoil reservoir back cover, A light tap on the looper

Fig. 6 drive lever rocker shaft, toward the operator is allthat is required, Then, using the looper drive lever

(C) to take up the end play between the looper drive lever rocker shaft and its synchronizing stud (A), tighten the looper drive lever on the shaft, with clamp screw (B),

Set the stitch to required length. This is accomplished by loosening lock nut(F, Fig. 15) 1/2 turn (it has a left thread) on the end of the stitch regulating stud andturning the stitch adjusting screw (G) located under the left end of the cloth plate inthe head of the main shaft (H) which is marked with “L” and “5”. Turning the screwin a clockwise direction shortens the stitch (moves stitch regulating stud toward the“S”) and turning it in a counterclockwise direction lengthens the stitch (moves stitchregulating stud toward the “L”). Retighten the lock nut securely. To prevent destructive damage to the feed drive bearing, the key screw (J) must engage the “uflshaped key slot in the ferrule (K).

On Styles 57700 R, S and V, the feed rocker assembly may require lubricationafter years of operation at the feed rocker needle bearings (L and M, Fig, 15). Thiscan be accomplished by loosening Allen screw (N) and remove shaft (P). Whenpacking needle bearings, parts must be clean and grease should be applied directlyfrom the tube to avoid contamination, Tube of grease can be supplied under partNo, 28604 P. Replace shaft inserting tapered end first and tighten screw (N).

THREAD TENSION RELEASE

The thread tension release is set correctly when it begins to function as thepresser foot is raised to within 1/8 inch (3,17 mm) of the end of its travel and isentirely released when the presser foot has reached its highest position,

If adjustment is needed, loosen tension release lever screw (A, Fig, 16) located at the back of the machine and move tension disc separator as required, Re-tighten screw, After adjustment there should be no binding at any point,

SETTING HEIGHT OF PRESSER BAR

The height of the presser bar (C, Fig, 4) is set correctly if it is possible toremove the presser foot when the foot lifter lever (B, Fig, 16) is fully depressed,Also there should be approximately 1/16 inch (1,59 mm) clearance between lowersurface of the presser bar connection and guide (D, Fig, 4) and the bottom surfaceof head opening in the bed when the foot lifter lever is released and the presser footresting on the throat plate, with the feed dog down below the throat plate,

If adjustment is needed, turn handwheel in operating direction until the needlebar is in the low position. Loosen screw (E, Fig. 4) then, while holding presserfoot down on the throat plate surface, pry up presser bar connection and guide witha screwdriver to obtain the 1/16 inch (1.59 mm) setting and retighten screw. Checksetting by turning handwheel so that needle bar is in its high position and see ifpresser foot can be removed as mentioned in previous paragraph.

METERING DEVICE ADJUSTMENTS

The metering device MUST operate freely with the connecting rod assembly(A, Fig. 17) positioned at any point in the clutch drive lever (B) and the clutchrocker shaft lever (C).

As sewing conditions require, moving the connecting rod assembly to the left,

in the clutch drive lever, increases the amount of elastic being metered; moving itto the right, decreases the amount of elastic being metered.

The clutch brake is set at the factory, though a considerable change in stitch

length may necessitate a change in the amount of brake pressure required to eliminate overthrow of the metering device at high speeds. Should adjustment be nec

essary, loosen nut (D, Fig. 17) and turn bushing (E) clockwise to lessen clutch

overthrow (viewed from the handwheel end of machine); turning bushing counterclock

wise acts the reverse. NOTE: Apply only enough brake pressure to eliminate over

rihe upper knife (I, I’ig. 18) should be set to align its cutting edge with thecenterline of right needle and to engage lower knife for full cutting length. This canbe accomplished by loosening screw (G) permitting upper knife to be moved forward or rearward; loosen screws (II and J) and turn eccentric (1K) as required toobtain proper positioning for up and down movements, Retighten screws securely.

Fig. 18A

Lower knife is spring pressed against upper knife. Pressure can be increasedor decreased by adjusting stud (A, Fig. 19) which is locked by nut (B). Lower knife

may be secured in any position by tighteningscrew (C) and locking nut (D) against supportbracket.

Fig. 19

With upper knife in UP position, set andlock collar (L, Fig. 18) so it barely contactslower knife block (D).

Set the lower chip chute to clear looper connecting rod and cast-off support plate. Set theupper chip chute to clear the lower chip chute atbottom of stroke and tight against the right sideof upper knife,

THREADING

Thread machine as indicated in Fig. 1 and start sewing on a piece of fabric.

ThREAD TENSIONS

The tension on the needle threads should be only sufficient to produce uniformstitches on the under surface of the fabric. Tension on the looper thread shouldbe just sufficient to steady the thread,

Set the needle thread frame eyelet hole 3/8 inch (9. 2 mm) above the center ofu.s mounting screw. Lower for more needle thread in the stitch, raise for less. Topof the take—up wire should be set even with top of the holes in the needle bar thread

eyelet when needle bar is at the bottom of its stroke. Lower this setting for less

needle loop, reverse for more loop.

slI”I’ING LOOPE It ThREAD TAKE—UP

The looper thread take-up (iV[, Fig. 18) is not spotted on the main shaft and,

consequently, can be set to compensate for varying conditions. It is set correctlywhen the looper thread is just cast off the highest lobe of the take-upwhen the point

of the left needle is clearly visible below the underside of the looper. The cast-offplate assembly (N) is adjustable, and its setting determines the amount of threadpulled off by the take-up. Moving the cast-off plate assembly up towards the bottomof the screw slots causes more thread to be pulled from the cones, and moving the

cast-off plate assembly down towards the top of the screw slots causes less thread

to be pulled. The cast-off plate assembly is set correctly when the looper thread justbecomes taut as the looper reaches its extreme position to the left. Additionallooper thread control can be obtained by raising or lowering the retaining finger(P) which is secured by screw (R). The retaining finger should be centered in thetake-up disc with its bottom edge set parallel to and approximately 3/16 inch(4. 76 mm) above cast-off plate assembly.

PRESSER FOOT PRESSURE

Regulate the presser spring regulating screw so that it exerts only enoughpressure on the presser foot to feed the work uniformly when a slight tension isplaced on the fabric. Turning it clockwise increases the pressure, counterclockwiseacts the reverse.

ORDERING REPAIR PARTS

ILLUSTRATIONS

This catalog has been arranged to simplify ordering repair parts. Explodedviews of various sections of the mechanism are shown so that the parts maybe seenin their actual position in the machine. On the page opposite the illustration will befound a listing of the parts with their part number, description, and the number ofpieces required in the particular view being shown.

Numbers in the first column are reference numbers only, and merely indicatethe position of that part in the illustration. Referencenumbers should never be usedin ordering parts. Always use the part number listed in the second column.

Component parts of sub-assemblies which can be furnished for repairs areindicated by indenting their descriptions under the description of the main subassembly. Example:

IT JAJST

It will be noted in the example shown on the previous page that the eccentricand bearing are not listed. The reason is that replacement of these parts 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 shownin this book. This will facilitate locating the illustration and description when onlythe part number is known.

IDENTIFYING PA RTS

Where the construction permits, each part is stamped with its part number, Onsome of the smaller parts, and on those where the construction does not permit, anidentification letter is stamped in to distinguish the part from similar ones.

Part numbers represent the same part, regardless of the catalog in which theyappear.

IMPORTANT! ONALL ORDERS, PLEASE INCLUDE PART NAMEAND STYLEOF MACHINE FOR WHICH PART IS ORDERED.

TORQUE REQUIREMENTS

Torque (measured in inch-pounds) is a rotating force (in pounds) applied througha distance by a lever (in inches or feet). This is accomplished by a wrench, screwdriver, etc. Many of these devices are available, which when set at the properamount of torque will tighten the part to the correct amount and no tighter.

All straps and eccentrics shouldbe tightenedto 19-21 inch-pounds (22-24 cm/kg)unless otherwise noted. All other nuts, bolts, screws, etc., should be tighenedby hand as tightly as possible, unless otherwise noted.

The screws requiring a specific torque, will be indicated on the picture plates.

to reduce needless maintenance costs.Repair Part Inventories

While record keepinq tells niaiiageinent wfticfi machines t equii t’

abnormally high niaintenaiicc, it does little to help reduce the dowot inncai.ised by routine repairs. To alleviate this situation, Union Sin’i i,ilrecommends that manufacturers establish a formal parts ioveiifoi ysystem for each fype of sewing machine they operafe.

Excessive machine downfime and wasted hours by mechanics canbe eliminated with an orderly in-plant inventory of the most commonlyneeded parts. There is no longer a need to cannibalize other machinesfor spare parts. Long waits for deliveries are avoided and machinedowntime is kept to a minimum. The cost of a parts inventory is smallwhen the overall savings are considered.

The first system utilizes a “Machine Maintenance Record cardIlni ti 237) for each sewing machine iii a plant. When a repair isinquired, the card is pulled from the file and the repair date, parts used,and their cost are entered in the spaces provided and the card is refiled.

The second system is normally used when more detailed informationon repair costs is desired. Two record cards are used: a “RepairRequest Card” (Form 234), and a “Machine Repair Record” (Form233), When a machine requires service, the [orelady or foreman fillsout the top of a “Repair Request Card’ and gives it to a mechanic.
