Foot Powered Hammer

The hammer handle is pivoted at B to the head of a vertical shaft, C, that is fitted in a socket in the top of the stand, so as to rise and fall, and to turn freely. The lower end of the shaft has a step in the lever, F, which is pivoted to the hind leg of the stand, and extends forward and alongside of the anvil block, where its free and is to be used by the operator for raising and lowering the hammer, as the work may demand. A bar, I, having a series of holes, is attached to the stand and arranged in a slot through the lever, F, for fastening the lever at any point by a pin, in order to set the hammer at the required height. An arm, M, is attached to the lower end of the shaft, C, over the lever, O, pivoted to the lever, N, near the anvil block, within easy reach of the operator. By moving the lever, O, which is held in position by a pin passing through holes in a plate on the lever F, the shaft is turned and the hammer swung along the face of the anvil.

The hammer handle is connected to a foot lever, Q, by which it is worked by a cord, S, which passes through a slot in the handle and connects by a ring with a rod, on which a coiled spring, W, is fitted, to be contracted when the hammer is forced down, for raising the hammer again. The spring bears against the head of the shaft, C, and the rod connects with the free end of the spring by an adjusting nut, which serves to regulate the tension of the spring. The shaft, C, has a vertical curved extension which supports a coiled buffer spring that arrests the hammer at the end of the up stroke without shock or jar. The hammer handle is adjustable forward or backward with relation to the anvil, by placing the pivot of the handle in slots.

This invention has been patented by Mr. John L. Painter of Bellevue, Ohio.
