Abstract

822,944. Control of motors. LEEDS & NORTHRUP CO. Jan. 15, 1957, No. 1522/57. Class 38 (3). [Also in Group XII] The control system for charging and discharging a batch-type furnace (see Group XII) through chain and sprocket gearing 44, 45, 46 driven by a reversible electric motor 53, incorporates cams 70a-70d mounted on a shaft 68a driven by said gearing and operating switches 75-78 associated with double-acting relays 80, 88. Closing " charge " button C energizes relay coil 80a, closing contacts 80b whereby current passes through switch 75 which is held closed by cam 70a to a " charge " starter 60 thus closing contacts 61 and starting motor 53. At the end of the charging movement, cam 70a opens switch 75 and cam 70b closes switch 76 energizing relay coil 80c and thereby opening contacts 80b to stop the motor. By this time, switch 77 will have been closed by cam 70c and switch 78 opened by cam 70d preparatory to an unloading movement initiated by closing " discharge " button D. The discharge movement is then controlled by relay 88, cams 70c, 70d and switches 77, 78 in a similar manner to that described for the charging movement.
