Title: Improvements in or relating to detaching devices for ropes
Inventor: WORRALL ROBERT WILLIAM
IPC: B66B5/08
Filed: 1959-09-15
Abstract: 892,108. Releasing cage from rope at limit of wind. RELIANCE ROPE ATTACHMENT CO. Ltd. Oct. 20, 1960 [Sept. 15, 1959], No. 31403/59. Class 78 (5). A coupling device is interposed in the winding rope between the cage (not shown) of a pit shaft and a winding drum, the arrangement being such that on overwind the member 4 of the coupling device connected to winding drum will be detached from the device, and the member 1 connected to the cage will be retained from falling back. Under normal conditions the members 1 and 4 are locked together by detent balls 3 which are held in the position shown in Fig. 1 by a locking member 6. On overwind, a flaired portion 25 of the member 6 engages a stop 21 (Fig. 5), further movement of the members 1 and 4 then resulting in compression of a rubber spring 15 by the action of a pin 10 carried by the locking member 6 and movable in slots 11 in the member 1. The locking member 6 reaches the position shown in Fig. 2 in which the detent balls 3 are moved into a position releasing the member 4 from the member 1 and locking the member 1 relative to the member 6. In the course of this movement a sleeve 40 is drawn with the member 4 by a bolt 41 into a position in which it is maintaining the detent balls 3 in their position locking the members 1 and 6. The sleeve 40 is then arrested by the action of a stop 43 rigid with the member 1 and movable in a slot 42 of the sleeve 40. Further movement of the member 1 thus ruptures the bolt 41 and releases the winding rope. The connecting device then falls back on to pawls 26 which restrain the cage from further movement.
