ABSTRACT:
Apparatus for transferring torque from a driving shaft to a driven shaft include an outer coupling body attached to the driven shaft defining an interior cylindrical cavity and which is movable both rotatably and axially between an idling and a coupling position, an inner coupling body disposed within the cavity having a lower portion concentric with respect to the cavity and an upper portion having an interior coupling surface eccentric with respect to the cavity. The driving shaft extends within the inner body and has a first coupling member engaging the interior coupling surface and a second coupling member which engages the inner coupling body when the outer coupling body is in its idling position and which is disengaged therefrom when the outer coupling body is in its coupling position. When the outer coupling body is in its idling or disengaged position, the inner coupling body rotates concentically within the interior of the outer coupling body due to the engagement of the second coupling member with the inner coupling body. Upon the outer coupling body being moved to its coupling position, the second coupling member becomes disengaged from the inner coupling body whereupon the inner coupling body which tends to rotate about its eccentric axis through engagement between the first coupling member and the interior coupling surface, tilts and binds against the interior cavity to rotatably couple the outer coupling member to the inner coupling body.
