UNITED STATES PATENT OFFICE.
MELLEN BRAY, OF NEWTON, MASSACHUSETTS.
RIVET.
SPECIFICATION forming part of Letters Patent No. 402,649, dated May 7, 1889.
A Application filed January 3, 1889. Serial No. 295,373. (No model.)
To all whom it may concern;
Be it known that I, MELLEN BRAY, of Newton, in the county of Middlesex and State of Massachusetts, have inventeda new and useful Improvement in Rivets, of which the following, taken .in connection with the accompanying drawings, is a specification.
`My invention relates to rivets for securing together two or more pieces of leather, cloth, rubber, or other like materials, and to that class of such rivets as are provided with a plurality ofprongs which pass through the material and are clinched thereto upon the side thereof opposite to its head; and it oonsists in certain novel features of construction, which will be readily understood by reference to the description of the drawings and to the claims to behereinafter given, and in which my invention is clearly pointed out.
Figures l and 2 of the drawings are respectively a plan and an elevation of my improved rivet. Figs. 3, 4, 5, 6, and 7 are views of the blank from which the finished rivet is formed, and illustrate the severalY steps in its manufacture, as will be herein after explain ed.-
My improved rivet is composed of the head a, a shank, b, having two prongs, c c, each having a rounded outer side and a fiat inner side, and also having its end beveled both upon the outside, as at d, and upon the inside, as at d', as shown in Figs. 1 and 2.
The distance from the outside of one prong i c tothe outside of the other prong c is somewhat greater than the greatest diameter of the shank b at its junction with the head a, and the inner ilat faces of saidprongs are parallel, or nearly so, to each other, both transversely and longitudinally, for about half their length, while the remaining portions diverge from each other longitudinally, as shown in Fig. 2. The prongs c c are some- 'what narrower at their entering or piercing end than at their junction as viewed at right angles to Fig. 2, as shown in Fig. 7.
In the manufacture of :my improved rivet I first make a solid rivet with a countersunk point and having the outer corner of its shank beveled, as clearly shown in Figs. 3 and et. I then subject the Yshank of the solid rivet or blank to the action of compressingdies to iiatten said shank upon two opposing sides, and expand the end portion of said shank in a direction at right angles to the line of movement of saiddies, the flat surfaces formed upon the opposing sides of said shank being slightly inclined toward each other, as shown in Figs. 5, 6, and 7. I then place the flattened shank between a pair of suitable cutting-dies and punch out the central portion of the metal to form the prongs c c, as shown in Fig. 2. This Vmethod of forming a pronged rivet forms the subject-matter of another application of even date herewith, and is not claimed herein. By this construction I produce a rivet the prongs of which are very strong and having central cutting edges and parallel side for a considerable portion of their length, whereby said prongs are adapted to out their own way and pass directly through a comparatively hard material-such, for instance, as hard sole-leather--without being deflected either toward or from each other to an inj urious extent.
It will be observed on reference to Fig. 2 that the inner flat faces of the prongs c c are not only parallel, or nearly so, to each other for a considerable portion of their lengths, but each inside flat surface is in like manner parallel, ornearly so, longitudinally to the outside of the same prong.
What I claim as new, and desire'to secure by Letters Patent of the United States,-is-
1. A rivet made from solid wire provided with a head and two prongs, each having a rounded outer surface and a iiat inner surface, said inner surfaces of said prongs being parallel, or nearly so, longitudinally to each other and to the rounded outer surfaces of said prongs for a considerable portion of their lengths, said prongs being provided with central cutting-edges and made tapering widthwise from their junction to their cutting ends, and having a distance from the outsidev of one prong to the outside of the other greater at the point where said prongs are parallel to each other than at their junction with each otherv and with the head.
2. A rivet made from solid wire provided with a head and two prongs, each having a rounded outer surface and a fiat inner surface, sald flat inner surfaces being parallel,
or nearly so, longitudinally with each other and with the outer rounded surfaces of said Aprongs for a considerable portion of their IOC lengths, each of said prongs being provided to this speeiieatiomin the presence of two sub- With a central cutting-edge, and the distance seribing witnesses, on this 24th day of Deeem- 1o from the outside of one prongr to the outside ber, A. D. 1888. of the other being greater at the point Where 5 said prongs are parallel to each other than at their junction with each other and with the ivitnesses: head. N. C. LOMBARD,
In testimony whereof I have signed my name WALTER E. LOMBARD.
