To (0Z5 whom it may concern.-

Be it known that I, CHARLES HENRY SCHMIDT, a citizen of the United States, residing in Winchester, county of Fayette, State of Texas, have invented certain new and useful Improvements in Staple-Setting Implements 5 and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has for its particular object to provide a simple and effective hand instru ment or tool for uniting together by small metallic staples pieces of leather, canvas, or other fabric, and the implement is especially useful in making and mending harness, belting, shoes, &c.

Generally speaking, the invention consists of a pair of nipper or tong like jaws, one of themselves after passing through the material being operated upon. This kind of instrument is not broadly new; but my improvement embodies novel features of construction which enable the staples to be driven at any desired angle without changing the angle of the .jaws to the work.

In some kinds of saddlery-work, and especially in making and mending shoes, it is very desirable to put the staples in line with the seams, so as to imitate a line of stitches, and as the seams are oftenangular and crooked it is necessary to constantly change the angle of the tool to the work; but this cannot always be done when working in corners and on the interior of hollow articles, such as boots and shoes, and I propose making the staple-carrier and anvil (one or both) adjustable in the jaws of the implement, so as to drive and clench the staples in any line desired, and, specifically, my invention consists in the means whereby I do this.

I have illustrated one form of myinven Lion in the accompanying drawings, wherein Figure 1 is an elevation of the entire device. Figs. 2 and 3 are face views of the staple-carrier and anvil, respectively; and Fig 4 is a sectional view of both jaws, showstaples through the work, and the jaw A is r the one carrying the anvil, against which the ends of the staple strike and which acts to turn them inwardly and clench them.

The staple-holder is denoted by the letter O, and consistsof a block having a pair of jaws c c, projecting toward thejaw of the instrument which carries the anvil; The stapleholder is arranged to slidein the plunger of the instrument,so thatit mayrecedeinto the same as the plunger is pressed against the anvil, the rear part of the plunger being cut out for this purpose, as shown at cl in Fig. 4. Projecting rearwardly the staple-holder O has a stem or heel extension 6, which passes out through a perforation p in the jaw A in line with the jaws c c of the holder 0, and on the outer side of the plunger-carrying jaw A of the instrument itself there is a spring .9, riveted so that its free end bears against the heel extension and keeps the staple-carrying jaws c c normally projected beyond the end of the plunger and yet allows them to withdraw or recede into the plunger when the latter is pressed against the anvil.

The plunger or staple-driver is denoted by .here shown for so mounting it (though the invention is not limited to these particular means) consist of two springs ff, riveted or otherwise secured, as illustrated in Fig. 4, to opposite sides of the plunger-carrying jawA and extending toward the anvil in the opposite jaw A parallel with each other in the plane the plunger is'intended to have. The plunger is cylindrical in general outline, but

has its exterior provided with a plurality-0t fiat surfaces 2'. surface of the plunger is octagonal; but the invention is not limited to the number of angularsurfaces,hut only that they should be polygonal. As will be seen from the drawings, particularly Figs. 2 and 4:, the springs fflie upon opposite sides of the plunger and inelose it throughout its length, bearingeaeh on one of the flat faces of the plunger-body. At their outer ends the springs ff have inturned points h h, which stand in toward each other and overlap the front end of the plunger. These points serve to prevent any accidental displacement of the plunger endwise, and the springs bearing on its flat exterior surfaces on opposite sides serve to hold it against accidental rotation at the same time. The springs permit the plunger to be adjusted around its longitudinal axis into as many positions as there are fiat surfaces on its exterior, and the points h It, being only spring-held in place, permit its ready removal. In order to seat the plunger firmly in its carrying-jaw A, the end of the latter is cut away, asshown at t t, seas to form a shoulder to back and hold the same.

As will be understood from Figs. 2 and 4, the staple-carrying jaws stand on opposite sides of the longitudinal center of the plunger, and the carrier is so mounted in the plunger that though it can slide in it it cannot turn except the plunger itself turns. In all the figures of the drawings the staplecarrying jaws are shown as standing-in line with the handles of the instrument. In this position the direction of the staples would of course always be in line with the handles; but, as before stated, when working in corners or on the interior of hollow articles-such as boots, shoes, (inc-it is frequently impossible to hold the handles at the angle required in order to place the rivets in line with one another,- and it is here that myinvention finds its principal advantage, for, as will be readily understood from the drawings, it is only necessary to rotate the plunger and staple-holder and set it at whatever angle may be desired when the work may proceed, and it is to be particularly noted that in doing this it is unnecessary to remove either the staple, the plunger, or the staple-holder.

Referring now to the anvil-carrying jaw A, (best illustrated in Figs. 3 and 4,) E denotes the anvil. All instruments of this character require an anvil of some sort, and my improvement in respect to this feature consists in making it revolubly adjustable on its seat and in the particular construction of the an vil and seat. The anvil itself consists of a block of metal having a rear\vardly-projecting tang that enters a depression or perforation in the jaw A. behind the seat proper.

The anvil is revolubly secured in or upon its seat in any preferred way, friction being relied on in the form shown in the drawings. In order to provide the seat for the anvil, the end of the jaw A is cut away, so as to leave In the present drawings the a ledge c and a shoulder or abutmentf, and the ledge is provided on its upper surface with polygonal faces e as clearly shown in Fig. 3. The periphery of the head or body part of the anvil E is also provided with a plurality of angular or flat faces to correspond with those of the seat 6. The object of this construction of the anvil and its seat is to provide for the before-described revoluble adjustment of the anvil to correspond with the similar adjustment of the staple-carrier and plunger. The anvil is firmly held from rotation by the side faces of the seat, and in order to adjust it it is only necessary to partially remove it with the thumb and forefinger, turn it to the required angle, and rein sert it.

Such being the construction of my improved implement, no explanation of its operation seems necessary further than is clearly indicated in the above description. It is to be understood, however, that the adjustable feature of the anvil is not necessary to the suecessful working of the adjustable staple-carrier. with two little depressions g g, which are curved or cam-shaped on the bottom and into which the free ends of the staple enter and are deflected inward toward each other. When such depressions are employed, it will probably be necessary to make the anvil adjustable; but should these depressions be omitted or' modified in form or arrangement it would be unnecessary to have the anvil rotatable.

The arrangement shown in Fig. 5 is slightly different from that of the other figu res in that the angular faces of the anvil are provided with depressions u, and the arm A has a spring-pressed pin 0', adapted to engage the depressions and hold the anvil in any position. The pin 0' has 381112111]. thumb-screw a: projecting through a slot outwardly,by means of which the pin maybe withdrawn to permit the anvil to be rotated. In this arrangement the tang of the anvil passes clear through the end of the arm A and has a head 0, and the anvil is freely rotatable without removal and does not rely on the angular faces of the seat for holding it in place, as in Fig. 3, there being enough clearance to permit it to turn.

Having thus described the invention, what I claim is- 1. In a staple-setting tool, the combination (with the jaws of the implement, of a revolubly-adjustable plunger having a polygonal exterior surface and mounted in a yielding hearing or support, a staple-carrier mounted in said plunger, and a polygonal seat in the plunger-carrying jaw on or in which said plunger may be adjusted.
