Title: Improvements in electric welding rod holders
IPC: B23K9/28
Filed: 1944-07-06
Abstract: 585,41,5. Welding electrode holders. ANTHONY, W. C. July 6, 1944, No. 12917. [Class 39 (iii)] [Also in Group XXIX] Electric welding rods are held between jaws closed by fluid pressure means. In an example air or other fluid is supplied under high pressure through a pipe 29 and passages 26, 30 to a cylinder 22 and piston 23 to close jaws 1, 11 and grip the rod. Depression of a valve member 38 allows the air to escape through ports 32, thereby cooling the handle, and a spring 20 to the open jaws. Continuous additional cooling may be obtained by escape ports 41 in an opening 39 controlled by an adjustable member 40. In a modification, Fig. 7 (not shown) semi depression of the valve member 38 allows air to escape from 26 through a passage in the part 36 into the handle, but maintains pressure in the cylinder to hold the jaws closed until the member 38 is fully depressed. The piston 23 may be of metal but is preferably covered with or made wholly from an insulating material such as neoprene to prevent arcing. The piston and cylinder assembly may be replaced by any other pressure means, e.g., flexible bulb or bellows of rubber &c. If a liquid is used instead of air a return passage is used instead of discharge ports. The spring 20 is preferably insulated from the jaw arms 4, 15. In another example, Figs. 4, 5 and 6 (not shown) the jaws are both opened and closed by fluid pressure means. The jaws are connected by toggle mechanism to a piston sliding in a cylinder, fluid being admitted to either end of the cylinder as determined by a spring-loaded hand operated valve (see Group XXIX], the fluid ejected from the other end of the cylinder being passed via the valve into the handle to cool it. ' The fluid is supplied by a tube passing through the centre of the electrical conductor.
