Abstract
622,595. Locking rotary elements. FREEBORN POWER CONVERTERS, Ltd., FRAINE, A. F. DE., and SANDELL, K. C. March 31, 1947, No. 8697. [Class 80 (iv)] A uni-directional pawl and ratchet device comprises a fixed housing 3, inside which is secured an annulus 2 having on its inner surface ratchet teeth 1 adapted to engage pawls 10 pivoted to shoes 11 resiliently mounted between equi-spaced blocks 22 on the outside of a rotatable disc 6. If disc 6 is rotated above a certain speed in a clockwise direction, centrifugal effect pivots pawls 10 clear of ratchet teeth 1 against the force of springs 16 ; stoppage or reverse rotation of disc 6 locks pawls. 10 with the ratchet teeth 1 and the resultant shock is absorbed by the pawl shoes 11 compressing the coiled spring 20 by which they are spaced from the blocks 22 rigid with the disc 6. Specification 439,828 is referred to.
