The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), if the GT contains lines used for stylistic emphasis or as background elements (like ruled paper), the OCR result must ignore them. The provided OCR content is "____", which consists of four underscores. This is incorrect because underscores are not equivalent to a solid line and are not permitted under the “Stylistic/Background Lines (Ignore)” rule. The OCR has hallucinated underscores where none should exist in the GT, violating the “Stylistic/Background Lines (Ignore)” rule. Therefore, the OCR result is inconsistent with the Ground Truth.

FOREWORD

The 50000 series streamlined machines covered by this catalog represent the latest design of the Union Special flatbed line. Light weight needle bars and driving mechanisms and light weight presser bars make it possible to attain the utmost in speed and production. Automatic lubrication, with a pump for returning filtered oil to the main reservoir, has made maintenance simple. All parts are made by precision methods insuring complete interchangeability.

It is our constant aim to furnish carefully prepared information that will enable the customer to secure all possible advantages from the use of UNION SPECIAL machines. The following pages illustrate and describe the parts used in all of the machines covered by this catalog.

Additional catalogs, containing information relative to these machines, and which will be furnished on request, are listed below:

Catalog No. 45 N Form 357

Needle Manual Engineering Department Adjusting Instructions. Specify the style of machine for which the adjusting instructions are required.

In all manufacturing centers will be found Union Special representatives, who will co-operate with those who desire in planning and estimating their requirements.

NOTE: Machine Styles listed in this catalog are discontinued. In most instances, component parts can be ordered for customer repair.

Each UNION SPECIAL machine 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 BP". Style numbers containing 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 BPZ".

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: "51400".

The distance between the rows of stitches on machines in Classes 51400, 51500, 51700, 51900 is represented by a gauge number measured in 1/64ths of an inch. Thus, 12 gauge represents a distance of 12/64 or 3/16 inch. Similarly, 64 gauge represents a distance of 64/64 or 1 inch.

NEEDLES

TYPE NUMBERS AND SIZES

Each needle has a type number and size number. The type number denotes the kind of shank, point, length, groove, finish and other details. The size number denotes the largest diameter of the blade, measured in thousandths of an inch, midway between the shank and the 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 number should be given. See remarks on labels. An intelligent order would read as follows: "1000 Needles, Type 108 GKS Size 090/036".

The type numbers of the needle recommended for each style of machine covered by this catalog are given in the machine style description. Other needles are available but the ones indicated are those recommended to produce the most satisfactory results. The type numbers of the recommended needles together with their descriptions and the sizes available are listed below:

ILLUSTRATIONS

This catalog has been so arranged as to simplify the ordering of repair parts. Exploded views of the 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 the listing of the parts with their part numbers, descriptions and the number of pieces required in the particular view being shown.

The numbers in the first column are reference numbers only and indicate the position of that part in the illustration. The reference number should never be used in ordering parts. Always use the part number shown in the second column.

Those component parts of sub-assemblies which can be furnished for repairs are indicated by the fact that their descriptions are indented under the description of the main sub-assembly. Example:

3	29105 Z	Looper Drive Eccentric Assembly, for Styles in Classes 51300, 51500; Styles 51200 BL, BM, BT, BW, BX; 51900 BH, BJ--1
4	22559 A	Bearing Cap Screw, lower ----2
5	22559 B	Bearing Cap Screw, upper ----2
6	22894 C	Eccentric Set Screw ----4
7	22894 D	Eccentric Spot Screw ----1

It will be noted in the above example that the eccentric, ball stud and bearing are not listed. The reason for this is that the replacement of any of these parts individually is not recommended and the complete sub-assembly should be ordered.

ORDERING REPAIR PARTS

ILLUSTRATIONS (Continued)

In those cases where a part is common to all of the machines covered by this catalog, no specific usage will be mentioned in the description. However, when the parts for the various machines are not the same, the specific usage will be mentioned in the descriptions and, if necessary, the difference will be shown in the illustration.

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

IDENTIFYING PARTS

Where the construction permits each part is stamped with its part number. On some smaller parts and on those where the construction does not permit, an identification letter is stamped to distinguish the part from similar ones.

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

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 Corporation, its subsidiaries and authorized distributors. They are designed according to the most approved scientific principles and made with the utmost precision. The maximum efficiency and durability are assured.

Genuine needles are packaged with labels marked Union Special®. Genuine repair parts are stamped with the Union Special trademark, U S Emblem. Each trademark is your guarantee of the highest quality in materials and workmanship.

TERMS

Prices are strictly net cash and subject to change without notice. All shipments are forwarded at the buyer's risk f.o.b. shipping point. Parcel post shipments are insured unless otherwise directed. A charge is made to cover the postage and insurance.

OILING AND THREADING INSTRUCTIONS

The oil has been drained from the machine before shipping and the reservoir must be filled before beginning to operate. Use a straight mineral oil with a Saybolt viscosity of 90 to 125 seconds at 100^ Fahrenheit.

Oil is filled at the spring cap in the top cover and the level is checked at the sight gauge on the front of the machine. The oil level should be maintained between the red lines on the gauge. The capacity of the oil reservoir is 12 ounces.

The machine is automatically lubricated and no oiling other than keeping the main reservoir filled is necessary.

A daily check before the morning start should be made and oil added if required. Oil which has gone through the machine is filtered and pumped back into the main reservoir making too frequent oilings unnecessary. Excessive oil in the main reservoir may be drained at the plug screw in the main frame directly under the handwheel.

The accompanying drawing also shows the manner in which a two needle machine is threaded. Single and three needle machines are threaded in substantially the same manner. The looper threading of the various classes is indicated in the inserts.
