lIMPROVl-ID PUNCH.

To ALL wHoM rr MAY eoNonnN:

Be it known that I, LORENZ WOLF, of St. Jacob, in the county of Madison, and State of Illinois, bave invented a new and useful Improvement in Punches and I do hereby declare thatthe following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a front elevation of my improved fpuneh. v

Figure 2 is a horizontal section ofthe same, the line a.' x, fig. 1, indicating the plane of section.

Similar letters of reference indicate like parts.

The object of this invention is to provide a standard for guiding a slidingpunch in such a manner that the socket in the standard may be enlarged or diminished at pleasure, according to the diameter or size of the tool which isto slide therein. y

The invention consists in providing a groove in the face of a curved standard. rising from a bedplate, the latter being, by means of screws or otherwise, secured to lsuitable supports. A groovedcap is screwed to the face of the standard, and by the grooves in the said standard and in the cap, a socket is formed which corresponds with the square or polygonal shank of the punch that is to slide in the said socket. Between the lcap yand standard are provided India-rubber or other springs, which, in connection .with the screws by which the cap is held to the standard7 serve to allow the adjustment of the cap for larger or smaller-sized Shanks.` The said Shanks need not be made as accurately when to be used in this machine, as the latter is made so that considerably different sizes of Shanks can he used therein, and, consequently, the manufacture' of the punches forithisV machine will be less expensive than for any other knowndevice for similar purposes. In the aforesaid bed-plate is provided a cavity for receiving dies of different sizes, to correspond to different punches, which may be-insertcd in vtheir sockets so that holes of diierent sizes can be punched `in iron or steel with ease and rapidity.

A represents a-punch, with a square or polygonalshank, a, which is fitted in a corresponding socket in the end of an arm or standard, B, rising from the bed-plate C. Half of this socket is formed in shape of a groove in the face of the said arm B, and the other half in a cap, D, which is fastened to the arm by means of screws b b, as shown. Between the cap D and arm B are arranged India-rubber or other springs d d, which, when aV larger socket is required, serve to keep the cap rni, while it is, by means of the screws, set from the face of the arm B. To get a more accurate guidance for the punch, the socket is hollowed out in the centre, only its upper and lower end coming in contact with the shank. The standard B is so curved that pieces of metal of various width may be admitted under the punch; and the socket, in its upper end, is of suicient length to guide the punch perfectly. The bed-plate C is provided with a hole, e., large enough to let the burs of the largest punch to be used pass freely. This hole terminates on top in a cavity, f, which is to receive the dies; and the latter are so arranged as to be readily changed in accordance with the size of holes to be produced.

I claim as new, and desire to secure by Letters Yatent The grooved cap D, curved and grooved standard' B, screws b, and springs d d, in combination with the punch and die, all as set forth.
