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 contain the letter "Z". Example: 51400 A. Style numbers contain the letter "Z" are special. When only minor changes are made in a standard machine a "Z" is merely suffixed to the respective standard style number. Example: 51400 AZ.

Styles of machines similar in construction are grouped under a class number which differs from the style numbers in that it contains no letters. Example: 51400.

The distance between the rows of stitches is represented by a gauge number measured in 64ths of an inch, viz: 9 gauge represents a distance of 9/64 inch; 64 gauge represents a distance of 64/64 inch, or 1 inch. The gauge number of machines, making three independent equally spaced rows of stitches, represents the space between adjoining rows or one-half the overall measurement, viz: No.6 gauge represents 6/64 inch or 3/32 inch, No.9 gauge represents 9/64 inch.

APPLICATION OF CATALOG

This catalog applies only to the standard styles and gauges of machines as listed. It can also be applied with discretion to the special machines in the "Fifty Thousand Series".

NEEDLES

TYPE NUMERS 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 type 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 106 Size .036". The type numbers of the needles most commonly used in the styles of machines covered by this catalog are listed below. Set opposite each type number is the definition of the needle.

ORDERING REPAIR PARTS

PLATES

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

When a given design of presser foot, looper, throat plate or other part is made in two or more gauges or sizes, only one illustration is usually 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 definition of each part and its principal uses will be found. Always check the symbol against its definition before ordering. It is not necessary to furnish the plate number.

When a part is used, or can be used in all machines covered by this catalog, no specific use is mentioned in the definition.

For convenience in ordering, minor parts such as screws, nuts and similar articles are repeated after each major part.

(一) A dash in the "plate number" column of the list of parts indicates the absence of an illustration.
(□) A square in the "symbol to order by" column indicates that the part is commercial and can be readily purchased in any machinist's supply house.
(‡) A double dagger in the "symbol to order by" column indicates that the component parts cannot be furnished separately.

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, creamers, belting, belt hooks, belt fasteners, screw drivers, wrenches and powdered oil stone will be promptly furnished.

USE GENUINE NEEDLES AND REPAIR PARTS

Success in the operation of these machines can be secured only by the use of genuine Union Special Needles and Repair Parts as furnished by the Union Special Machine Company, its subsidiaries and authorized distributors. Obviously, it is to
