Abstract
678,466. Winches. WHARTON CRANE & HOIST CO., Ltd. March 22, 1951. [March 23, 1950] No. 7255/50. Class 78 (v). In two-speed winding apparatus of the kind in which the drum is driven by either of two A.C. motors, the drum 1 is driven through reduction gearing by a shaft 2 which is driven directly by the motor 3 and through reduction gearing 5 and a friction clutch 6 of the toggle type by a squirrel-cage motor 4, a brake 13 being provided to hold the shaft 2 when neither motor is energized. The clutch 6 is actuated by a yoke 7 keyed to a cross-shaft 8 which is rocked by a lever 9 actuated by an electrichydraulic thrustor 10 pivoted to the frame and push-buttoned controlled. A weight 11 disengages the clutch when the thrustor is de-energized. The yoke 7 moves slightly further after the clutch is engaged fully and this movement closes a switch 12 to energize the motor 4. The switches of the motors are interlocked so that only one of them can be energized at a time.
