. CANADIAN PATENT APPLICATION APPLICANT: DARCIE FRANK REYNOLDS TITLE: DRUM WINCHES ABSTRACT OF THE DISCLOSURE A drum winch for a yacht has a drum rotatably mounted on a supporting shaft structure through roller clutch means to permit rotation of the drum in one rotary direction only and seal means are provided for sealing the roller clutch means from the exterior of the winch, the seal means preferably being of a stretched O-ring arrangement mounted over an annular ramp-like surface having a radially inwardly directed component. The roller clutch means is dimensioned relative to the exterior diameter of the shaft structure and/or relative to the internal diameter of a central bore in the drum so that a yieldable interference fit is established with lubricant whereby if the load applied to the drum exceeds a predetermined load which is less than the load which would cause damage or destruction of the roller clutch means, creep or slippage occurs at the yieldable interference fit. A novel profile for the drum is also provided and a bayonet-like mounting plate arrangement to permit quick mounting and dismounting the drum winch is also disclosed.
