Abstract

1,238,864. Welding by pressure. P. ESSER. 18 July, 1968 [19 July, 1967], No. 34152/68. Heading B3R. [Also in Division F2] A chain welding machine is provided with an electromagnetic clutch 26 for connecting the drive from a motor-driven pulley 24 to the shaft 30 of the machine and also comprises devices for feeding, fixing, upsetting and welding the chain links, a brake for acting on the shaft 30 and devices for monitoring and controlling the machine and chain movement. The electromagnetic clutch comprises a hub 28 secured to pulley 24 and rotatably supporting the end of the shaft 30, an electromagnetic coil 34 in the hub, an armature disc 36 axially movable but non-rotatably mounted on shaft 30 and a brake pad 42 non-rotatably mounted. The armature disc, which has a friction lining 37, is urged by springs 40 towards the brake 42 which also has a friction lining 39 so that upon de-energization of coil 34 the disc 36 is rapidly braked and rotation of shaft 30 is stopped. Current to the coil 34 can be controlled by each of the individual control devices, and a main switch may also be provided.
