Title: Improvements in and relating to means for hoisting and lowering a life boat or similar devices
IPC: B63B23/18
Filed: 1949-06-20
Abstract: 680,006. Winding and paying-out apparatus. SCHATS DAVITS, Ltd., and SMIRNOFF, V. June 20, 1949. No. 16345/49. Class 78 (v). A life-boat winch or like winch wherein a fall rope is wound upon a fall drum operated by an auxiliary rope, which is hauled by power driven gear and wound upon an auxiliary drum coupled to the fall drum, is characterised in that the fall drum and auxiliary drum are co-axially mounted on an axis between two adjacent bearings for said axis, and the two drums are separated by a gap smaller than the diameter of either the fall rope or the auxiliary rope so that neither rope can fall or foul between said drums. Figs. 1 and 2. The boat 5 is raised and lowered by two falls 6 and 7. The winding drum comprises a portion fixed to shaft 14 in the normal way, which portion comprises the sections 10, 11 and 13, Fig. 2, while a section 12 is freely mounted on the shaft to leave only said small gap between it and the sections 11 and 13 on either side. Fall 7 is wound on section 10 in the normal manner but fall 6 is wound across both sections 11 and 12, the boat being in the raised position, Fig. 1. A rope 23 secured at 22 by means of a bolt is allowed to wind up across section 12 as the falls 6 and 7 are paid out. The boat can thus be rehoisted by engaging rope 23 with a hauling winch drum 25. Rope 23 need not be engaged with the apparatus until after lowering when it may be fastened at 26 to section 12 instead of at 22, section 12 being rotated to wind on sufficient rope for hoisting, after which the end fastened at 26 is removed to point 22 on section 13. Fig. 3. In the case of multiple layer winding the sections 10 and 11 are normal size for winding the falls 6 and 7, and section 13 is dispensed with. Fall 6 does not now wind over on to section 12, but rope 23 which is now to be wound entirely on section 12, during or after lowering, as above described, has its end attached to the section 11 at 22 for re-hoisting. Alternatively rope 23 is permanently attached to section 12 and either a removable link is secured between points on the surfaces of sections 11 and 12, or these sections are provided on their adjacent surface edges with lugs which may be aligned for passing a bolt through aligned holes in them.

Abstract: 449,586. Variable-pitch propellers. FAIREY AVIATION CO., Ltd., and FAIREY, C. R., Cranford Lane, Hayes, Middlesex, and FORSYTH, A. G., Venlaw, Burdon Lane, Cheam, Surrey. June 6, 1935, No. 16494. [Class 114] [See also Group XXIV] In worm reversing- gearing, the direction of rotation is reversed by altering the sense of the worm and to this end a single convolution of the worm is formed as a discontinuous resilient circular rib e, Figs. 1 and 2, which is adapted to lie in either of grooves c or d on a worm shaft a to form either a right-hand or left-hand worm, a further groove b being provided for an inoperative position of the rib e. With this arrangement the change of sense of the worm has to be effected manually when the parts are stationary, but in the arrangement in Figs. 7 and 9, the change can be effected during the relative rotation of the parts. This arrangement illustrates the application of the invention to variable-pitch propellers, the worm shaft a being stationary and worm wheels such as f, secured to individual propeller blades, having a planetary motion around the axis of the shaft a. The worm comprises as before a resilient circular rib e secured at one end to the shaft, the other end being secured to a block m which is capable of lateral movement in a slot n to move the rib e into the left-hand or right-hand thread position against the helical side walls of a groove h, or to retain it in its central and neutral position as shown. This lateral movement of the rib e is obtained by axial movement of an inner sleeve j, to which the block m is secured, slidably keyed to the shaft a and movable by means of pins t engaging in inclined slots v, these pins being secured to a rotatable control ring q and projecting through slots u in the shaft a.
