Abstract

532,648. Welding. HOLDEN, T. F., and HOLDEN, R. W. Sept. 19, 1939, No. 26106. [Class 83 (iv)] An electrode of a spot or other electric welding machine is operated by an hydraulic ram formed as a unitary construction with the pressure pump and an electric motor for driving the pump. A cylndrical oil tank 1 axially and angularly adjustable by handles 22 in a bracket 18 on the machine frame carries at one end the hydraulic ram cylinder 4 and at the other a rotary pump 2 and an electric motor 3. The pump delivers oil through passages 7, 8 to the ram cylinder when a valve 5 provided with parts 9, 10 is in the position shown in Fig. 3. The passage 7 feeds the oil to a central plug 16 which engages a recess 17 in the ram to avoid packing. The pressure is indicated by a gauge 15 and is adjusted by a control valve 13 bridging the passage 8 and oil tank. When the valve 5, which may be operated by a ram on a continuosuly driven shaft or by a pedal is rotated into the dotted position, the pump delivery and the ram cylinder are both placed in oommunication with the tank the ram 14 being returned by a spring. To the ram may be secured a holder such as a double split clip. The clip may be constructed for holding an electrode in alignment with the ram or for holding it at one side thereof. The work may be supported on interchangeable cantilever brackets mounted on a vertical slide.
