The striking beam of this hammer is of hardwood tapering from 4x3 1/8-inches on one end to 3½x3½ inches at the other. A box is mounted under the beam by a fork passing through the shaft; on this shaft which passes through the box are four springs mounted two on the lower and two on the upper part, thus cushioning is secured by these springs which are easily adjusted for any kind of work. An adjustment in the connecting rod enables the operator to raise or lower the head as the work may require. For metal trade the hammer is built with a horn attachment, the beam being supplied with a special gripping device to grip either a wooden, rawhide, or steel hammer. The power is applied by means of a foot lever which draws the loose pulley up to the belt, regulating the force of the blow by the pressure of the foot. The hammer weighs about 500 pounds, takes up a floor space of 24x32-inches, and will strike about 300 times per minute. The hammer is mounted on a wooden base, if so desired. The maker is Fritz A. Schulz, 66 North Jefferson street, Chicago, Ill. |
