In the Berwick and Humil ma-. A Two-Head General Electric Rivet Heater chines the rivets being heated are connected in multiple,while in the General Electric machine two rivets are con-nected in series. The operation of heating rivets is very simple. The cop-per blocks which form the secondan,- terminals are forcedapart by a handle or foot treadle, a rivet is placed endwisebetween the blocks, and on releasing the handle or treadlethe blocks are made to grip the rivet by their weight or bysprings, depending on the type of machine. A stop pre-vents the blocks from coming in contact with each other whenthere is no rivet between them. The electric furnace is clean, gives off no objectionablegas and the rivets are always in plain view of the rivet is heated from the inside and the shank becomeshotter than the head, due to its lesser cross section. These areideal upsetting conditions, as the heat is applied exactly whereit is needed, and the head, being cooler, is less malleable andis therefore less likely
