SECTION I - CLASS DEFINITION

This class includes generally chain, staple, horseshoe, and ox-shoe making, swivel making being included under Chain making.

Also the article subclasses of Chains, including general purpose and ornamental chains and swivels.

For further explanation in regard to what may be included in the above art and article subclasses, see the definitions, particularly those given under the head of each of the arts.

Chain Making. Relates to the broad art of chain making and includes all patents for machines, apparatus, blanks and processes relating to the manufacture of chains or links, except such as shall be referred to hereinafter. Includes patents relating to the manufacture of swivels (see References to This Class, below).

(1) Note. The manufacture of simple links for car-couplings will be found in appropriate subclasses under this head.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

Rolling machines or rolls designed especially for the manufacture of chains, chain-links, horseshoes, horseshoe bars or calks, and staples in which there is invention in the construction or operation of the means or parts which give the form to the blank or article produced are included in this class; otherwise in Class 72, Metal Deforming.

If the invention resides simply in the manner of attaching the dies to the rolls, the patents will be found in Class 72, Metal Deforming.

This class is closely related to Classes 29, Metal Working; 72, Metal Deforming; 83, Cutting; and 140, Wireworking, which classes should be kept in mind in completing a search in this class.

Machines which coil the wire or rod into a helix or which coil the helix and cut-off coils or sections to form links are found in Class 72, Metal Deforming. If the machine, in addition to coiling and cutting, gives link form to the part cut off or assembles such parts into a chain, it will be classified in this class.

Electric heating and welding machines and processes comprising any invention in the means of applying or process of application are classified elsewhere. If however, the use of electricity is incidental and the claims embrace no novel features relating thereto, the patents will be classified herein.

(1) Note. The line between this class (59) and Class 206, Special Receptacle or Package, and Class 411, Expanded, Threaded, Driven, Headed, Tool-Deformed, or Lock-Threaded Fastener, is as follows: In this class (59), this subclass (77), the blank may have the appearance of a mass of partially-shaped, nonsevered, staple-like elements; however, significant additional shaping, plus severing, is required to convert the blank into a plurality of staples. In Class 206, subclasses 340+, the package may be one of severably-connected staples. In Class 411, subclasses 442+, a plurality of fasteners of the class are secured one to another, e.g., a strip of staples, etc.
