Abstract
An improvement to a conventional slap-hammer which allows the hammer to be rotated by a pneumatic wrench or like device. A universal joint is attached to the top of the slap hammer to enable the latter to be rotated by the output shaft of a pneumatic wrench. The housing of the wrench is held by a closable harness that encircles the housing when closed and thereby prevents the output shaft from becoming disengaged from the universal joint.
Claims2
A slap hammer designed for being driven by a pneumatic wrench and the like, comprising:
- a conventional slap hammer with an elongated body having a self-tapping screw at the bottom;
- a coupling detachably securing the top of the body to an output shaft of a pneumatic wrench whereby the wrench can rotate the body about its axis, said coupling including a universal joint for receiving the shaft and a flexible compressible hollow boot covering the joint when the shaft is secured to the joint;
- a harness detachably securing the slap hammer to the housing of said wrench;
- and
- a race of roller bearings secured to said body below the coupling, said harness encircling the race in a manner at which the race and harness are kept from separating and the race is allowed to rotate within the harness.
