Abstract:
Rotary input power is selectively coupled to an output shaft or the like by actuation of a plunger which forces a movable pin into a coupled relation between a member attached to the input drive and an arm attached to the output. A fixed wall establishes a guideway for the head of the pin until it reaches an aperture in the wall allowing pin extraction as by a spring, gravity or the like. Coupling is established by the pin passing through a hole in the arm attached to the output and a detent or transverse surface associated with the driven element. The device permits coupling a continuously rotating input to an output for one revolution although more or less than full revolutions are possible.
