JOSEPH P. I'IASTY, OF SUPERIOR, NEBRASKA.

STAPLE-SETTING HVI PLEiVl EMT.

SPECIFICATION forming part of Letters Patent No. 579,538, dated March 23, 1897.

Application filed February 2'7, 1896. Serial No. 580,955. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH P. I'IASTY, a citizen of the United States, residing at Superior, in the county of Nuckolls and State of Nebraska, have invented a new and useful Staple-Setting Implement, of which the following is a specification.

My invention relates to an improved staplesetting implement; and it has for its object the production of a device for setting wire staples in mending articles of leather or other like fabric, the implement being adapted to force the ends of the staple through the fabric, turn the points inward, and clench them, thus securing the pieces of fabric together.

The invention will first be described in connection with the accompanying drawings, and then pointed out in the claim.

Figure 1 of the drawings is a View in elevation of my improved implement, the stapleholder, plunger, and a portion of each jaw being sectioned. Fig. 2 is a perspective view of the plunger. Fig. 3 is a plan view of the head-plate and the staple-holder. Fig. 4 is a broken perspective view of the staple-holder, showing a staple therein. Fig. 5 illustrates a modified form of myinvention, showing a plan view of the staple-holder and the head-plate and a perspective View of the plunger used in such modified construction.

Referring to the drawings, A A represent two levers, the rear ends of which form handles and the front ends being curved to form jaws B B. These levers are pivotally connected at 1 and normally held in open position by a coil-spring 2 in rear of the pivotal point, as shown in Fig. 1.

0 represents the staple-holder, preferably rectangular in shape and having a central hole 3. In the holder in communication with the hole 3 and extending laterally therefrom are formed a number of recesses 4:, 5, 6, and 7, each of which extends on each side of the hole 3 and nearly to the bottom of the holder. These recesses are adapted to receive the staples, as shown in Fig. 4;, the first two, 4 and 5, being preferably formed at a right angle to each other, the remaining two, 6 and 7, being at an acute angle to the first two and to each other.

D represents a plunger which comprises a stem 8, the lower end of which is reduced at 9, and'a cap 10, secured to the upper end of the stem. From the cap project laterally

arms

11, 12, 13, and 14, each extending beyond the edge of the cap on each side and being adapted to work in the

recesses

4, 5, 6, and 7, respectively, the arms being of a height less than the depth of said recesses, as shown in Fig. 1. The plunger D is adapted to work in the holder 0, its arms lying in the respective recesses therein and its stem projecting throughthe central hole 3. The shouldered end 9 of the plunger is passed through a hole 15 in the lower jaw B and secured thereto by a nut 16. The jawB, surrounding the hole 15, is recessed, as at 18, forminga seat for one end of a coil-spring 19, which encircles the stem 8 of the plunger and bears at its upper end against the bottom of the staple-holder, as shown in Fig. 1, by which construction the cap and arms of the plunger are normally held to the bottom of the holder.

E represents a head-plate having a stem 20, which is passed through an opening 21 in the upper jaw B and secured in place by a nut 22. In the surface of this plate are formed a series of concave depressions 23, so located that when the staples are in place in the holder a depression will be directly above each end of each staple.

The staples F are placed in the holder, one lying in and being held upright by each respective recess.

In Fig. 5, I have shown a modified form of my invention, in which the staple-holder O is formed with parallel recesses 24:, 25, and- 26. The plunger 1) has lateral arms 27, 2S, and 29, adapted to fit and work in said re cesses, and the head-plate E has concave depressions 30, arranged and in sufficient number to coact with the staples placed in the recesses. The securing of the modified construction to the jaws and its operation by the handles will be understood without further description.

The parts being assembled as above described, the staples having been placed in their respective recesses, the operation of my improved implement is as follows: The ends of the fabric to be mended are brought together, preferably overlapped, and placed be* tween the head-plate and the holder above the ends of the staples. By pressing 011 the handles the parts on the jaws are moved together until the holder contacts With the under side of the material and the head-plate with the upper side. Further pressure on the handles Will cause the plunger to move gradually upward against the stress of spring 19, causing the staples to be forced out of the holder and into the fabric. When the ends of the staples have passed through the fabric, they will enter the depressions in the headplate, following which they will be caused, on continued pressure on the handles, to form return-bends 011 themselves and reenter the fabric. l/Vhen the plunger has moved upward until its upper surface lies flush with the upper edge of the holder, the staples will have been forced entirely out of the holder and into the fabric, the head-plate having caused the ends of the staples to have been clenched therein, thus forming a secure junction of the pieces of the fabric.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a staple-setting implement, the combination, with two crossed levers pivoted together, the forward ends of which are curved to form jaws, of a staple-holder having a series of vertical angular recesses of a suitable depth adapted to receive staples of different sizes and a central hole, a plunger-cap within the holder and shaped to conform to the angular recesses therein, a plunger-stem one end of which is secured in one of the jaws, its other end being passed through the hole in the holder and secured to the plunger-cap, a coiled spring encircling the stem between the jaw and the holder, and a head-plate secured to the other jaw.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOSEPH P. HASTY.
