APPLICANT: LANDSTINGENS INKOPSCENTRAL, LIC, EKONOMISK FORENING. TITLE: A MANUAL WINCH WITH SAFETY CLUTCH, ESPECIALLY AS A POWER SOURCE IN NURSING FOR LIFTING PATIENTS. ABSTRACT OF THE DISCLOSURE A winch operated by a manual crank and handle for reeling-up or out a belt or rope and including a holding catch for preventing reeling-out when the handle is not actuated. A friction coupling mechanism is momentarily released when the handle is moved in the reeling-out direction, resulting in that the load is moved downwardly and actuates a screw mechanism which momentarily locks the coupling if the handle is stopped. Reeling-out is thus effected by releasing and locking actions following each other at very small intervals, the reeling-out movement being practically synchronous with the movement of the handle until it is stopped.
