GEORGE H. MEADE, OF QUINCY, ASSIGNOR TO MELLEN B RAY, OF NEWTON, MASSACHUSETTS.

RIVET.

SPECIFICATION forming part of Letters Patent No. 328,704, dated October 20, 1885.

Application filed October 15, 1884. Serial No. 145,572. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE H. MEADE, of Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Rivets, of which the following, taken in connection with the ac companying drawings, is a specification.

My invention relates to the construction of rivets to be used for the purpose of securing 1 together two or more pieces of leather or similar material; and it consists in acertain novel construction which will readily be understood by reference to the description of the drawings and to the claims to be hereinafter given.

Of the drawings, Figure 1 represents a plan of my improved rivet. Fig. 2 represents a front elevation of the same. Fig. 3 represents a side elevation of the same. Fig. 4 represents a plan of the same after it 2c has been set; and Fig. 5 represents a section on line a; w on Fig. 4,showing the rivet in elevation as it appears when set.

A is a rivet made of metal and provided with the head a and shank b, which shank b 2 is provided with two flattened surfaces, 0 c, opposite to each other, which meet at the end of said shank b to form a suitable cuttingedge, (1, and thereby cause said shank to be wedge-shaped, as shown in Figs. 1, 2, and 3.

0 The shank b, at the point where it joins the head a, may be either round, square, oval, or any other desired shape in cross-section, but its cutting-edge d should be lengthwise of its greatest diameter. The cutting-edge d should 5 be sufficiently sharp to readily enter the material in which the rivet is to be set, and it is provided near the center of its length with a notch, 6.

On setting the rivet in the material B the 0 cuttingedge 01 cuts a path through which the shank bis forced a sufficient distance until the head of the rivet comes into contact with said material. \Vhile being thus forced through the material the cutting-edge comes 5 into contact at the notch 6 with a knife upon the anvil of the machine for setting the rivets, and by it is split or divided, as shown in dotted lines in Fig. 2, and one portion thereof is forced by said anvil in one direction, while the other is forced in the opposite direction. The anvil that accomplishes this object is necessarily of a novel construction, but needs no further explanation here, as it forms the subject-matter of another application of even date herewith.

This rivet may be made very strong, while, on account of its simplicity, it may be made quite cheaply.

I am well aware that nails and pegs have been made and are in common use which have shanks which are more or less tapering, but which would be wholly impracticable foruse as rivets in leather work, inasmuch as they have no cutting-edge by which a path may be cut through the material for the ready entrance of the shank b, and also as they are provided with no suitable shouldered heads between which and the upset ends the material may be clamped to prevent the heads from working their way through the material, as is the case with said nails and pegs; therefore I make no claim upon a rivet having a flat-sidedtapered shank; but

What I do claim as new, and desire to secure by Letters Patent of the United States, 7 1s- 1. A rivet provided with a head the under shoulder of which is at right angles,or nearly so, to the shank, and having a shank circular in cross'section at its junction with the head, and its two opposite sides composed of two converging flat surfaces which meet and form a cutting-edge at the end thereof, substantially as described.

2. A rivet the shank of which is provided at one end with a head the under side of which forms a shoulder at right angles, or nearly so, to the said shank, and at the other end with a knife or cutting-edge extending from opposite sides of said shank toward its center, and having midway of said cutting-edge a slight notch, all substantially as and for the purposes described.

In testimony whereof I have signed my name to this specification, in the presence of 5 two subscribing witnesses, on this 13th day of October, A. D. 1884.

GEORGE H. MEADE.
