ABSTRACT:
A pressure actuated force transmitting cylinder includes a housing member having first and second elongated portions. An end cap closes one end of the housing in a fluid tight manner. A connection is formed through such first portion for communicating fluid to such cylinder. A clutch having a first clutch surface is disposed on such housing and a piston-like member is disposed for reciprocal movement in such housing. A seal disposed around a peripheral portion of such piston-like member provides a chamber to receive such fluid. An elongated rod-like member, having a threaded portion, is connected to such piston-like member. A threaded nut member is threadedly engaged with such threaded portion. A trigger mechanism is disposed around a portion of such rod-like member adjacent such nut member. A disc-like member is disposed around such trigger. A first race assembly is abuttingly engaged with a flat surface formed on such nut member and a second race assembly is abuttingly engaged with another flat surface formed on such nut member. Such first and second race assemblies permit rotation of such nut member on such threaded portion. Finally a first urging mechanism, in combination with fluid communicated to such cylinder, urges such second clutch surface away from such first clutch surface and a second urging mechanism overcomes such first mechanism and urges such second clutch surface into engagement with such first clutch surface when pressure is absent in such cylinder.
