HENRY F. OSBORNE, OF NEWARK, NE\V JERSEY.
PUNCHING AND CUTTING PLIERS.
SPECIFICATION forming part of Letters Patent No. 317,181, dated May 5, 1885.
Application filed September 13, 1884.
T 00% whom, it may concern:
Be it known that I, HENRY F. OSBORNE, a citizen of the United States, residing in Newark, Essex county, New Jersey, have invented certain new and useful Improvements in Punching and Cutting Pliers, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
v This invention relates to a combination-tool consisting of a pair of pliers provided with a punch and with a pair of opposed cuttingedges, which are prevented from coming into contact by the seating of the punch.
The invention is intended for use as a beltpunch and rivet-cutting tool, by means of which a series of holes can be punched near the end of the belt; and in order that these holes may be at a uniform distance from the end, a step-gage may be employed upon one of the j aws, as shown in the drawings at Figure 1. The cutting-edges serve to trim 0d the point of the belt-rivet when the latter proves to be too long for the thickness of the belt operated upon.
I11 the drawings, Fig. 1 is a side View, and Fig. 2 is an edge View, of the pliers, and Fig. 3 is a front end view of the jaws opened.
In the drawings, A A are the handles, and B B, the jaws, of a belt-pliers provided with my improvements.
O is the punch; G, the brass seat against which it cuts, the punch being made tubular, as shown in the drawings.
The punch is shown screwed into the jaw B to facilitate exchange when a different size is required, and the wads of leather are thus discharged through the back of such jaw. With such a tubular punch the cutting of the wad from the punched hole can only be ef-' fected by pressing the punch hard upon the brass seat 0, and to combine a pair of wedgeshaped rivet-cutters, D D, therewith the latter must be so adjusted as not to come into contact or interfere with the action of the tubular punch. This adjustment of the cutters is possible because of the wedge shape or section of the cutting-edges D, which operate both to penetrate and push apart the metal, so that the rivets cut by the pliers are readily severed by cutting nearly through, while the (No model.)
affecting their operation upon a metallic rivet,
for the reason named above.
The cutters D are shown dovetailed into the sides of the jaws, as is common in other cutting-pliers, but may be formed and secured in any other convenient manner.
Astep-gage is shown in the drawings formed upon the jaw B, near the seat 0, and presents a series of ledges extending inward from the jaw and backward from the seat, so that the leather belt, when laid upon the seat to be punched, may have its end adjusted in contact with any specific ledge upon the gage, and the distance of the hole from the end be thus determined, the softness of the leather permitting it to bend when fitted to the more elevated ledges. The step-gage is not a part of my present invention, and is not claimed herein, although it may be used in connection with the other parts when desired.
In using my invention the operator applies the leather to the seat and gage and punches a series of holes in the opposed ends of a belt at the desired distances from the end, varying the use of the gage when it is required to arrange the holes at different distances from the edge. He then inserts the rivet in the lapped ends of the belt, and examines it to see if it projects too far for riveting, in which case it. would be bent when hammered upon the burr.-
Should the rivet be too long, he applies the cutters D and nips off the end of the rivet, applying the cutters in several positions around the point of the rivet if not cut through sufficiently the first time. The rivet being thus cut to the right length,the burr canbe applied and the riveting completed by any suitable hammering-tools. 4
My invention thus furnishes a tool adapted to complete the operation of riveting a belt in a more convenient manner, and accomplishes this result without impairing the usefulness of the punch in any degree.
I am aware of the state of the art shown in United States Patents Nos. 85,575, 147,792, posed and wedge-shaped cutting-edges, D,situand 156,619,2tnd do not therefore claim a punch ated at the base of the jaws and prevented from and shears combined, except in the precise contact by the seating of the punch, substanconstructio'n described. tial'ly as shown and described. I 5 5 Having thus fully set forth the nature and In testimony whereof I have hereunto set my objects of my invention, I claim the same as hand in the presence of two subscribing witfoilows: nesses.
