Abstract

1425016 Winches DONKIN & CO Ltd 9 Oct 1973 [24 Oct 1972] 48878/72 Heading B8B A winch comprises two barrels 11, 12 arranged to receive a cable 18, the barrel 11 being driven, first receiving the cable 18 and being disposed with its axis normal to the direction of the cable 18. The axes of the two barrels 11, 12 are inclined to each other at an angle given by the formula tanα=P1/D, where P1 is the pitch of the grooves on the barrel 11 and D the diameter of the barrels, the pitch P2 on the idler barrel 12 being given by the formula P2=P1/cosα.
