FOREWORD

The 5000 series streamlined zig - zag machines covered by this catalog represent the latest design of the UNION SPECIAL

flat bed line. Class 53100 machines offer many advantages on various operations on a variety of garments such as

nightgowns, slips, panties, foundations, children's knit undergarmrnts, men's trousers, women's dresses, blouses, bed jakets

and pajamas.

Light weight presser bar and needle bar driving mechanism make it possible to attain the utmost in speed and production.

The new light weight parts and needle bearings make them lighter running and smoother operating. The light weight presser

bar mechanism reduces pressure required to lift the presser foot.

Automatic lubrication and a new filter type oil return pump, used in conjunction with isolated mounting oil pan base plate,

for returning filtered oil to the main reservoir, has made maintenance simple.

IDENTIFICATION OF MACHINE

Each UNION SPECIAL machine is identified by a Style number which is stamped into the name plate on

the machine. Style numbers are classified as standard and special. Standard Style numbers have one or

more letters suffixed, but never contain the letter “Z”. Example: “Style 53100 A”. Special Style numbers

contain the letter “Z”. When only minor changes are made in a standard machine, a “Z” is suffixed to the

standard Style number. Example: “Style 53100 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: “53100”.

applied with discretion to some Special Styles of machines in this class. Reference to direction, such

as right, left, front, back, etc., are given from the operator’s position while seated at the machine.
