IDENTIFICATION OF MACHINES

Each Union Special carries a style number which is stamped in the name plate on the machine. Style numbers are classified as standard and special. Those which are standard have one or more letters suffixed, but never con~

tain the letter nz•. Example: 52700 A. Style numbers which contain the letter •zn are special. When only minor

changes are made in a standard machine a •z• is merely suffixed to the respective standard atyle number. Example:

52700 AZ.

Styles of machines similar in construction are grouped under a class number which differs from the style number in that it contains no letters. Example: 52700.

The overall width of the stitch in Classes 52700 and 52800 machines is represented by a gauge number measured in 64ths. ot an inch, viz: 16 gauge represents a stitch measuring 1/4 inch wide.

The distance between the needles perpendicular to the line of feed in Class 52900 machines is represented by gauge numbers measured in 64ths. of an inch. The number following the first hyphen(-) represents the distance between the left and middle needle and the number following the second hyphen(-) represents the distance between the middle and right needle, viz: 52900 A-5-8 gauge represents a distance of 5/64 inch between the left and middle needle and 1/8 inch between the middle and right needle.

The distance between the rows of stitches in Class 53500 machines is represented by a gauge number measured in 64ths. of an inch, viz: 16 gauge represents a dittance of 1/4 inch.

NEEDLES

TYPE NUMBERS AND SIZES

Each'needle has a type number and size number. The former denotes the kind of shank, point, length, groove, finish, and other details. The latter denotes the largest diameter of the blade, measured in thousandths of an inch midway between the shank and eye, and is stamped in the needle shank. Collectively, the typ~ number and size number is the complete symbol.

To have orders promptly and accurately filled, the empty package, a sample needle, or the type and size numbers should be given. See marks on packages. An intelligent order would read as follows "1000 Needles Type 121 Size 03211 •

ORDERING REPAIR PARTS

PLATES

Grouped, according to scale, will be found illustrations of parts similar in appearance, and, to som extent, component parts that go in the same subdivision of the mechanism.

When a given design of part is made in two or more sizes, only one illustration is uaually shown. In ordering these pieces it is necessary that the additional information be furnished as requested under these illustrations.

LIST OF PARTS

Turning from the plates to the list of parts, the description of each part and its principal uses will be found. Always check the symbol against its description before ordering. It is not necessary to furnish the plate numb~r.

When a part is used,			or can be used,	in all machines
covered by this catalog,			no specific use	is mentioned in the
description.				•
For convenience in ordering, minor parts such as screws,
nuts and	similar articles		are repeated after each maJor part.
(-)	A dash in the •plate number• column of the list of
parts indicates the absence of an illustration.
<i>	A double	dagger	in the •symbol to order by• column
indicates	that the	component parts cannot		be furnished

separately. Due to the high speed of these machines it is impossible tor these associated parts to be f1Lted a second time and make a serviceable Job.

IDENTIFYING PARTS

Where the construction permits, each part is stamped with its part number. Some of the smaller parts are stamped with an identification letter to distinguish them from parts similar in appearance.

All part numbers represent the same part, regardless of the catalog in which they appear.

SUPPLIES

All supplies, including taps, reamers, belting, belt hooks, belt fasteners, screw drivers, wrenches and powdered oil stone will be promptly furnished.
