Abstract

122,489. Heap, W. Jan. 26, 1918. Driving-gear for winding and paying-out apparatus. - A winding drum used on ships' davits for raising and lowering the boat is operated by epicycloidal gearing. The gearing employed is shown in Fig. 4 fitted to act as supplementary gearing on the davit operating-gear. The winding drum 31 is rotated by an internally toothed wheel similar to 18 adapted to be engaged by a gyrating toothed wheel 20 mounted on an eccentric 19 turning on an axle 13. The wheel 20 is prevented from rotating by pins formed on the wheel engaging diametrically opposed slots' in a floating disk 21, which has further slots engaging pins on a plate 23 adapted to be held against rotation by a chain secured to the fixed part of the framing. With the handle in the position shown in the Figures the gearing is in use, but when the chain is released and the set.screw undone to allow the handle to be lowered, the flat part 27<a> engages flats on both the sleeve 19<a> and boss 23<a> locking the whole of the gearing together so that it moves as a single member.
