Title: Improvements in and relating to mechanism for lifting floating bodies
IPC: B66D1/48
Filed: 1934-04-10
Abstract: 433,392. Winches. KAMPNAGEL AKT.- GES. VORM. NAGEL & KAEMP, 4, Barmbeckerstrasse, Hamburg, Germany. April 10, 1934, No. 10808. Convention date, July 22, 1933. [Class 78 (v)] [See also Group XXXIII] In winches for lifting and lowering loads from and on rough water, the cable supporting the load-carrying hook is furnished with two drives, one of which supports the load and the other rapidly takes up slack in the cable due to wave-action pressing up the load momentarily. The cable drum 1 is driven by a motor 2 through a clutch 3, pinion 4, intermediate wheel 5, and internal toothed ring 6. The wheel 5 is carried by a crank-pin on a shaft co-axial with the motor shaft and fitted with a gear wheel 8 driven by a pinion 9 on the shaft 10 of the auxiliary motor 11. The motor 11, which may be electric or weight-driven, tends continuously to tighten the cable, but its power is insufficient to raise the load. A brake 19 on the shaft 10 prevents the load falling by overcoming the motor 11, and the brake is always operative except when the cable is slack, the movement of the motor 11 in the lifting direction serving temporarily to switch off the brake. A suitable switch for this purpose consists of a spring-biassed lever mounted frictionally on the shaft 10 and moving to short-circuit the brake when the shaft 10 turns in the lifting direction.
