COMBINED PUNCH, SHEARS, AND SAW GUlVIIVIER.

SPECIFICATION forming part of Letters Patent No. 401,594, dated April 16, 1889.

Application filed September 1'7, 1888. Serial No. 285,568. (No model.)

To aZZ whom it may COUCH/7L! Be it known that I, JAMES SGHOFIELD, a citizen of the United States, residing at Petoskey, in the county of Emmet and State of Michigan, have invented certain new and useful Improvements in Combined Punch, Shears, and SawGummer; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a perspective View of my invention, showing it adapted for cutting off round and fiat bar-iron; Fig. 2, a similar view of the devices for attaching to the machine when used for gumming saws, and Fig. 3 a perspective view of the devices to be used in the machine for punching metal.

The object of the presentinvention is to provide a simple, practical, and easily-operating machine which can be used as a shears for cutting round and flat bar-iron, for gumming saws, and for punching metals, the several devices as they are required for use being connected to one and the same frame, which is adapted to receive them, and are quickly and readily removed and replaced by others adapted to do a certain class of work.

The invention consists in the general construction of the machine and its attachments, substantially as shown in the drawings and hereinafter described and claimed.

In the accompanying drawings, A represents the base of the frame cast with laterallyprojecting ears or, having holes therein to attach said base to a suitable supportby screws or other fasteni gs, as required. The base A is also cast with standards 13,110 which is pivoted the cam-lever G, cast with a socket, b, to receive a suitable handle, D. In the rear of the standards B are short standards E, to which are detachably pivoted the several tools as they are required for use. In Fig. 1 is shown the shear-blade F, pivoted to said standards by the pin 0, which is removable when it is desired to detach said blade. This blade in the position as shown is especially adapted to cut off round bar-iron, and when flat bariron is to be operated upon the blade F is re moved and reversed, the opposite edge thereof, as shown at (Z, being used. The stationary blade of the shears is shown at G, and is held firmly in position by means of the block 6 and set-screws f.

The base A and the standards B E constitute the frame of the machine, the front part of the base being cast with a seat, H,'to receive the stationary parts of the several tools.

The saw-gummer consists of the die I, having two bifurcations, g h, of difierent sizes, to adapt it to the gage of tooth required, and is held in the seat H by means of the set-screws and block, and may be reversed when required to bring either size of the bifurcation in use. The punch K, which operates with the die I, has its ends vij in size and shape to correspond with the bifurcations h, and has holes Znear each end for reversibly attaching it to the standards E by means of the pivotpin 0.

The punch for punching holes is shown in Fig. 3, and consists of the anvil orblock L, having a series of differentsized holes, as shown at m n, which may be of anynumber, and the block adjusted in the frame H so as to bring any one of the number of holes in position to be directly under the punch.

The punch, as shown at M, may be of various sizes to correspond with the sizes of the holes in the block L, and are detachably connected to the arm N, having at its rear end a hole, 0, for attaching it to the standards E. The shanks of these punches are made tapering and are inserted in the arm IT, as shown in Fig. 3. The punch K of the saw gumming tool will cut at either end and at either the top or bottom, thereby presenting four cutting sides to the two ends of the punch.

NVhen the machine is adapted to cut flat bar-iron, the blade G is reversed to bring the flat edge up, and the blade F is also reversed, as previously stated.

The sheanblade F has a rear extension to form an arm, P, which is similar in construe machine that will do the required Work as expeditiously as possible.

Having now fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with aset of reversible and detachable tools, of a frame to which the tools may be interchangeably connected, consisting of the base A, cast with standards B E, and seat H, and ears a, and the cam-lever O, pivoted to the standards B, substantially as and for the purpose set forth.

2. The combination, With the frame constructed substantially as described, and provided With a cam-1ever,0f the reversible blade F, detachably connected to the frame, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the pres ence of two Witnesses.

JAMES SOHOFIELD.
