ABSTRACT:
The present invention discloses an improved chain assembly and a method for making the same. In general, the method of making a chain assembly in accordance with the present invention, comprises forming a plurality of links having a preselected shape and placement of apertures therein. A plurality of wire blanks are formed having an outer diameter to permit insertion into the apertures of the links. Such link is retained in a fixed position and a wire blank is inserted into each aperture of the link. On one end of each wire blank, a head is formed having a diameter larger than the aperture into which the wire blank is inserted. A mating link is placed into engagement with each link containing wire blanks with the end of each blank inserted in one aperture of the mating link in a manner to form a chain assembly. On the other end of each wire blank, a head is formed to complete interlocking of the links and blanks in forming the chain assembly.
