IDENTIFICATION OF MACHINES
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 52700 BK ". 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 52700 BKZ ".
The over-all width of the stitch or the distance between the outside needles (extreme left and right) is represented by a gauge number. The actual spacing between the center lines of the outside needles, as applied to these machines, is as follows: No. 8 gauge • 125", No. 12 gauge • 172" and No. 16 gauge • 234".
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: "5270011 •
APPLICATION OF CATALOG

Reference to direction, such as right, left, front, back, etc. , are given from the operator's position while seated at the machine. Operating direction of handwheel is toward the operator.

NEEDLES
Each UNION SPECIAL needle has both a type number and a size number. The type number denotes the kind of shank, point, length, groove, finish and other details. The size number, stamped on the needle shank, denotes the largest diameter of blade measured in thousandths of an inch, midway between the shank and the eye. Collectively, the type number and the size number is the complete symbol.
The type numbers of the needles 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:

NEEDLES (continued)
Selection of proper needle size should be determined by the size of the thread used. Thread should pass freely through the needle eye in order to produce a good stitch formation.
ORDERING REPAIR PARTS
ILLUSTRATIONS
This catalog has been arranged to simplify ordering repair parts. Exploded views of 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 a listing of the parts with their part numbers1 descriptions~ and the number of pieces required in the particular view being shown.
Numbers in the first column are reference numbers only1 and merely indicate the position of that part in the illustration. Reference numbers should never be used in ordering parts. Always use the part number listed in the second column.
Component parts of sub-assemblies~ indicated by indenting their descriptions assembly. Example:
which can be furnished for repairs1 are under the description of the main sub-

It will be noted in the above example that the eccentric and bearing are not listed. The reason is that replacement of these parts individually is not recommended1 so the complete sub-assembly should be ordered.
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 same1 the specific usage will be mentioned in the description, and if necessary1 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 this book. This will facilitate locating the illustration and description when only the part number is known.
IDENTIFYING PARTS
Where the construction permits1 eachpart is stamped with its part number. On some of the smaller parts1 and on those where the construction does not permit, an identification letter is stamped in to distinguish the part from similar ones.
Part numbers represent the same part, regardless of the catalog in which they appear.
IMPORTANT! ON ALL ORDERS, PLEASE INCLUDE PART NAME AND STYLE OF MACHINE FOR WHICH PART IS ORDERED.
TERMS
Prices are net cash and are .subject to change without notice. All shipments are forwarded f. o. b. shipping point. Parcel Post shipments are insured unless otherwise directed. A charge is made to cover postage and insurance.

SELF-PRIMING HEAD OIL SIPHON
Class 52700 machines are equipped with a self-priming head oil siphon. When the m~chine is started, oil splashes on the priming cup felts, filters through the felts,
and tr1ckles down the vertical oil tube .. thus, priming the siphon. Once the prime is established, it is maintained, unless the felts are removed. The siphon operates twenty-four hours a day.. removing oil at the rate of six to twelve drops per minute, which of course, far exceeds the rate at which oil collects in the head.

INSTALLING AND MAINTENANCE OF OIL SIPHON
A newly installed siphon starts its action within three to five minutes after the machine is operating. However.. it may be twenty minutes or so before all the air is removed from the line and the siphon is in full operation. Within an hour.. there is a distinct drop in oil level in the head sump.
The felts in the priming cup are designed for a specific purpose. The bottom felt, 666-209, is thin and relatively dense, to meter the flow ofpriming oiland to prevent the entrance of air. The softer top felt, 666-201, is a filter to prevent theelogging of the metering felt. This felt, at the intake of the siphon, keeps the siphon clear of lint, and prevents the entrance of air at that point. For the best initial self-priming condition, the felts of the siphon should be dry. In this condition, it is difficult for air to be trapped between the felts or in the top soft felt itself.
However, if for some reason the priming cup felts had been oiled before installing, the siphon may fail because air is trapped between the felts or in the soft top felt. As a precaution, remove the soft felt from the cup. Then, while squeezing the felt between th~ fingers, saturate it well with oil. In other words, squeeze out the air and replace it with oil. Then, completely fill the cup with oil, and push or twist the soft felt down into cup so that it definitely contacts the harder thin felt. This precaution prevents the trapping of air, and no trouble should be experienced when starting the siphon.
If you want to be doubly sure that the siphon is functioning correctly, on a machine in operation, apply a certain amount of oil in the sump around the felt in the head. Before doing this, be certain that this felt has been saturated in the same manner as explained for the soft felt in the top of the siphon cup. When this is done, the siphoning action will begin, and the oil will be removed as explained.
