Abstract

1,107,130. Ratchet clutches. H. C. WEBB & CO. Ltd. 10 Nov., 1966 [10 Nov., 1965], No. 47605/65. Heading F2C. Ratchet clutches for lawn mowers are essentially similar to those described in Specification 1,107,129, having a clutch disc with punchedout fingers co-operating either with oppositely directed fingers of a similar disc or with the aperturesproduced by forming such fingers, but one clutch disc 16 is fast with a pulley 15, and the other disc 17 can be withdrawn axially by way of a fork 43 and bearing 34.
