NORMAN B. JONES, OF MURPHYSBOROUGH, ILLINOIS.

LEATHER-CUTTER.

$PEC'IFICATION forming part of Letters Patent No. 358,779, dated March 1, 1887..

Application filed December 4, 1886. Serial No. 220,711. (No model.)

To all whom it may concern:

Be it known that I, NORMAN B. JoNEs, a citizen of the United States, residing at Murphysborough, in the county ofJackson, State of lllinois, have invented certain new and useful Improvements in Leather-Cutters, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to devices for cutting leather, and more particularly to that class thereof for cutting whan gs, shoe-strings, straps, and strips; and the object of the invention is to provide a cheap and simple device of the above character which is easy of manipulation and effective in operation.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particu' larly pointed out in the claims.

Referring to the drawings, Figure 1 is a plan view of myinvention. Fig. 2 is a perspective of the table detached. Fig. 3 is a side elevation of the handle of that side thereof opposite the table, and Fig. 4 is a side elevation opposite that shown in Fig. 4. Fig. 5 is a detail in perspective of the traveler.

Like letters of reference indicate like parts in all the figures of the drawings.

A represents the handle, which is formed with the socket or projecting portion A, and

which is provided with the transverse recesses A A (see Fig. 4) and the vertical recess A (See Fig. 3.)

B represents the table, which is of substantially disk shape, and is provided with the cut-away or recessed portion, B, and the forwardly-projecting arms 13 which are adapted to enter into the recesses A of the socket. Formed on the surface of the table is a longitudinal groove or way, B and adapted to ride therein is a traveler, B, (see Fig. 5,) at one end of which is an upwardly-projecting spur, B

\Vithin the recess A* is a block, A which is provided with an overlapping or projecting portion, A, under which the leather passes when being revolved upon the table, and is slotted, as at A for the reception of a setscrew, A whereby said guiding-block is vertically adjustable.

A block, A carrying a knife, A is adapted to enter the transverse slot A of the socket, said block being held in position by means of a set-screw, A, inserted longitudinally through the forward end of the socket and bearing on said block, whereby said knife and block are adjustable to and from the table. The knife A is provided with two cutting'edges, and is removably mounted in a transverse slot in the block, it being held in a fixed position therein by means ofa set-screw, A, passing longitndinally through said block. By reason of the knife being removable from the block and provided with two cutting-edges it may be reversed, bringing either cutting-edge into operation.

The operation of my invention is readily apparent from the above description, and is as follows: If it be desired to cut a strip or whang from a piece of leather, X, the spur B is inserted at the center thereof, it being understood that the device is held in one hand and the cut is then started by drawing the leather between the knife and guard or guiding block A By taking. hold of the portion or strip thus started and drawing steadily upon the same a strip of leather of desired width may be drawn or cut, the length of which is only governed by the size of the piece from which the strip is being cut, or it may be severed into suitable lengths by drawing the strip transversely against the opposite cutting-edge of the knife. As the leather is cut the piece revolves upon the spur B of the traveler B, which automatically moves along the groove 13 toward the knife. B is in reality a centering-traveler, in that it automatically moves toward the knife A in relation to the amount of leather removed by said knife, so as to keep the center of rotation of the leather at a proper distance from the knife to insure a uniformity in the width of the whangs. While it is possible, by removing the centering-traveler from the table, to out straight pieces or straps, it is preferable to remove the table also, as the material-for eX- ample, a side of leather-from which a strap is to be cut is always at the side of the knife at which the table is located, and therefore the instrument can be used with greater ease and accuracy if the table is removed. I therefore the material X upon the table to dray." the table toward the knife, is a sufficient means of connecting the table to the latter. Still, as before stated, I deem the removable connection of the table to the handle as a broad and important feature of my invention. By adj usting the knife-carrying block A toward or from the guide-block A the width of the strip may be varied as desired.

By reason of the guide'block A being adj ustable vertically different thicknesses of leather-or, in fact, two or more'layers-may be cut at the same operation, the block being adjustable to such a position as to allow them to pass freely under the overlapping portion A of the same, thus presenting the leather squarely to the knife and rendering the strip being cut uniform, which otherwise would not be the case, as the leather has a tendency to curl when brought into contact with the knife. Upon the handle is formed a fixed guide, A, which coacts with the adjustable guide to produce a strip of uniform width.

If desired, the table B may be removed and the handle and knife used to cut straps, halters, 8m, from straight pieces of leather. For this purpose the socket portion of the handle is adapted for the removable connection therewith of the table, as hereinbefore described; but I do not limit my invention to the exact form of table and knife connecting joint or may substitute for this construction any wellknown detachable connecting construction,

Having thus fully described my invention and its operation, what I claim is 1. In a leather-cutter, the combination of a handle provided with a knife, of a table removably connected with the handle, and a centering-traveler, substantially as specified.

2. In the leather-cutter herein described, the combination of a handle having a socket recessed to receive a knife-carrying block, with a table adapted to enter recesses formed in the socket and provided with a leather-carrying traveler, all substantially as specified.

3. In a leather-cutter, the combination of a handle provided with an adjustable knife and guard and recesses, with a table adapted to enter said recesses, substantially as specified.

4. The combination of the handle A, formed with the socket portion A and recesses A A A. with the adjustable knife-carrying block A", having the knife A the guiding-block A slotted, as at A, and having the set-screw A with the table B. having the guide or way B recessed, as at B, and provided with the projections B adapted to enter recesses in the socket, substantially as shown and described."

5. The combination of the table B, having the recess B and projections B", and provided with the longitudinal groove B and the traveler B, mounted in said groove and having the spur B of the handle A, having the recessed socket A, adapted to receive said fable, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
