Link Forming And Joining Apparatus
View pageUS Patent:
55928099, Jan 14, 1997
Filed:
Feb 14, 1995
Appl. No.:
8/389134
Inventors:
Anthony Marcotrigiano - Rumford RI
James T. Pepper - Coventry RI
James T. Pepper - Coventry RI
Assignee:
Crafford Precision Products Co. - Riverside RI
International Classification:
B21L 102
US Classification:
59 25
Abstract:
Apparatus is disclosed for forming a single wire link which can be joined to a preformed jewelry article. The apparatus includes an electric motor-driven cam assembly that provides for sequential operation of the wire feeding and link forming devices. A single wire section is severed from a wire stock, bent into a U-shaped configuration and fed to a link forming station within a common working plane where the U-shaped wire element can be formed into a link and joined to a jewelry article. The link forming apparatus avoids the use of a magazine for storing a plurality of U-shaped wire element thus eliminating unused U-shaped wire elements in the magazine when switching wire stock. The apparatus is constructed in a manner which readily permits quick and easy changing of the feeding and forming dies when switching to different size wire stock. The apparatus further provides a simple adjustment mechanism for adjusting the length of the wire section severed from the wire stock.

Assignee:
Crafford Precision Products Co. - Riverside RI
International Classification:
B23K 912
US Classification:
2191251
Abstract:
Arc welding apparatus for use in conjunction with conventional link forming apparatus is operable for welding the closed ends of a link after it is formed. The electrode is mounted on a swinging arm which presents the electrode from the front of the assembly and positions the electrode substantially over the top of the link for welding thereof. The vertical, horizontal and angular positions of the electrode are adjustable by means of threaded adjustment knobs. A shield and gas tube are mounted adjacent to the tip end of the electrode and move simultaneously with the electrode into position over the link during a welding operation.
