ABSTRACT:
A drive shaft socket mounting arrangement to receive a socket or other tool having a tool end with a selected geometrically configured cross section to receive a tool to be attached to the shaft where a central, axial, bore is provided in the shaft and adapted to receive a slide. A first hole of selected first diameter is provided diametrically through the shaft a selected distance from the end of the shaft and passes through the axial bore. An elongate ring forms a sleeve having a cross drilled hole of second diameter smaller than the first diameter where the ring has a selected internal diameter larger than the diameter of the shaft is provided so that the sleeve is received on the shaft and so the cross drilled hole can be aligned with the first hole and where the sleeve has a lip adjacent the end opposite the end of the shaft so a portion of the sleeve forms an annular opening between the shaft surface and the inner surface of the sleeve. A pin having a diameter approximately equal to the diameter of the cross drilled hole is received in the crossdrilled hole and extends diametrically through the sleeve and shaft. A slide member is received in the axial bore and has a diametrically extending second hole positioned so that the pin extends through the second hole and the slide can be moved longitudinally in the axial bore by longitudinal movement of the sleeve on the shaft which moves the pin in the first hole. A radial cross drilled hole is provided in the tool end to receive a ball which can be positioned outwardly from the surface of the tool end to be received in a groove in the tool to be attached to the tool end and retracted into the tool end to release the tool. The slide has a groove in the surface thereof and can be moved from a first position to receive the ball to remove the ball from the tool to a second position to urge the ball into the tool. A spring is provided to urge the sleeve and slide to the second position where the slide is moved to the first position by movement of the sleeve.
