Description:

Claim:

A torque driver including means to connect to a part to be acted upon thereto comprising in combination; a deformable driving riiember; means including a driven member mounted in said driving member; tapered surfaces on said driving riiember and said driven member, one of said surfaces being further provided with a plurality of spaced cams and with non-driving areas between said cams; a roller cage; rollers in said cage and disposed for engagement with one said tapered surface and said camds so that said driving member when rotating will deliver torque to said driven member upon slight pressure of said means including said driven member against said part; means for selecting the maximum value of the driving torque beyond which value the forces will be sufficient to cause a radial deformation of the driving member and allow the rollers to ride over the cams and into the non-driving areas comprising axially movable means supported at least in part by said driven member, radially movable means supported at least in part by said driven member and interengaging said axially movable means whereby radial movement thereof causes axial movement of said axially movable means to change the distance between said tapered surfaces, and rotatable means externally supported on said driven member and operatively associated with said radially movable means for movement thereof; means for maintaining said rollers in the non-driving areas as long as said selected maximum value of said driving torque is exceeded and so long as said slight pressure on said part is maintained; and means to return said rollers to near engagement with said cams upon release of said pressure of said means including said driven member on said part.
