ABSTRACT:
A device for transforming a reciprocating linear movement into a rotary movement comprising a first member adapted for reciprocating axial movement relative to a turnable second member, means for displacing said reciprocating first member in opposite linear directions, at least a pair of annular sleeves disposed in a space between said first and second members, each sleeve having a frustoconical tapered surface confronting and adapted for torque transmitting engagement with a corresponding tapered surface on one of said members, the surface of each sleeve opposite the frustoconical surface confronting a surface of the other one of said members and guide means including at least one helical groove in one of said confronting surfaces and a guide element engageable in said grooves, actuation of said one member linearly in one axial direction causing engagement with the frustoconical surface of one sleeve to prevent turning relative to said one member and through said guide means rotation of said other member, actuation of said one member linearly in an opposite axial direction causing engagement with the frustoconical surface of said other sleeve and through said guide means rotation of said other member.
