Specification iii-tiling part of Letters Patent No. ESllZJlflllfEh, tinted. April 8, i879; appliealii'm filcu Novcmhcr l6, li'iei.
fit'oall crime! it may concern:
Be it known that l, Antenna 1%. lfllUlAliDS, oi lllillord, in the county of lforccstcr and State of Iliassaclnnwtts, have invented certain new and useful Improvements in ilych-t and Tulnilar-Rivct Setting Tools, of which the fol lowing, taken in connection with the accompanying drawings, is a specification.
My invention relates to improvements in tools for setting eyelets and tubular rivets in leather or other flexible material.
A portion of my present invention is an improvement upon the invention described in Letters Patent No. 124,3-i6, granted to me March 5, 1872, and the other portions are equally applicable to all eyelet or tulmlur-rivet setting machines; and it consists in forming in the end or shoulder of the clinching die or anvil a series of radial grooves, each having a curved bottom oi uniform width throughout and inclined sides, the inclined side of one groove meeting the inclined side of the next groove at an acute angle, so as to form a cutting hnifecdgc, each of which serves to split the end of the eyelcttuhe as thcseh tingtools are brought together to clinch the eyelet, and at the same time the inclined sides of said groove serve to press inward upon the material the edges of the section of the eyelet-tube formed by two contiguous slits made by the cutting edges or knives, causing; the outer surface of said section to assume a convex form, and thus remove all. projecting sharp or ragged corners.
It further consists in forming a concave recess in the upper end of the punch or male die, ofa diameter somewhat less than the di' master of said punch, that portion oi the end of said punch outside of said concave recess being made hevcling, so as to form an annular surface slightly conical or inclined downward and outward, to first come in contact with the leather and he pressed into it as the punch is moved upward, and thus prevent the punch from being sprung to one side and thrown out, of-linc with the female die.
Figure l of the drawings represents a piece of leather, having set therein three eyelets set by my improved tools, and three eyelets set with the old or commonly-used tools. Fin. 2
is a side elevation Ul a niroi' male and female dies adapted to punch tliehole in the material, insert the eyelet, and clinch the same. Fig. 3 is a central longitudinal section of the same dies. Fig. it is an inv *rted plan oi'the female die. Fig. 5 is a side elevation of a pair of set-tingtools adapted to insert the eyelet in a hole previously punched, and clinch the same by my improved tool; and Fig.. 6 is a central longitudinal section of the same setting-tools.
in Fig. I, A A A are eyelets set in a piece of leather by my improved tools, and B B B represent eyelets set by the old-style tools, or those now in common use, which tools, in the majority of cases, caused one or more breakages in the clinched end of the eyelet, as shown in thedrawings. When such break occurs the rugged corners of the break are left exposed, and act injuriously upon other articles of clothing with which they come in contact, as in case of their application to various articles of wea rinn'apparel.
To obviate this objection, I split the end of the tube of the eyelet into a series of divisions, a, While in the act of setting the eyelet, and turn each oi said divisions a over onto the material, and at the same time cinboss or press inward upon the leather or other material their outer edges, so as to remove-all projecting sharp or ragged corners, and produce an ornamental rosette-like finish upon the side of the material upon which the cycletis clinched of uniform appearance.
To accomplish this, in connection with tools adapted to punch the material, I insert the eyelet and clinch the sanic at one operation, as described in the Letters Patent heretofore cited. I form in the working-face oi the fe male die or clinching-anvil C aseries of radial grooves, b I), having curved bottoms, each of uniform width throughout, and inclined sides, so arranged relative to each other, that the inclined side of one groove meets the inclined side oi a contiguous groove at air-acute angle, thereby forming a knife-edge or cutter, c c, between each two contiguous grooves, which knife-edges first come in contact with the end of the eyelet-tube as it is forced up through the leather or other material and split it into a series of divisions, which are then turned over by thecurved bottoms of the grooves b I); end the beveled sides of the grooves. b b,
,aeting in conjunction. with said curved bot- --'to|ns, press theonterodges-of the leaves a. at
of the clinched flange into the materiel, so. that the outer surface of each ofsaid leaves are left convex.
The inale punch or setting-tool D has in its end the concave recess d, the greatest diametor of which is somewhat ,less than the diameter of the punch, the surface of the end of said punch which is outside of said recess being, inclined downward and outward from the mar gin ofsaid recess o that when said-punch comes in contact with the leather to be punched it shall rresent a narrow annular surface to the leather, and by virtue of its forml be embedded therein before the corners of the punch, working in conjunction with the cutting-edge of the female die 0, begin to cut the material, and thereby prevent the punch springing to one side or out of line with the female die, to the injury of said female die, as is liable to braille caseinpunching heavy greasy cowh ide with the center-ended punch described in my patent before fited.
F is estetionary clinching-tool, ind G a movabie plunger to work in connection therewith,
and adopted to set eyelets in holes previously punched. These tools are essentially the same as those in common-use in themnjority of-oyeletsctting machines now in use, except. that F and G, (shown in Fig. of my present invention,
said recess, substantially as and for the shoulder h of the tool F has formed in its face a series of radial grooves, b b, and cutting-.- edges 0 0, formed and adapted to operate subetautislly as shown in Fig; 4,, end descrihm in thel reference to the frneiedi'e or fciincfiugtoo v The other details of construction oi the tools need no further do scri ption here.
Vhet I claim as new, by Letters Patent of the United'Stetee, is,-
1. The clinching-tool G or F, having formed in its working face or shoulder a series of rodial grooves, b 11, each having ecurved bot tom of uniform width throughout and inclined sides, and a series of cutting knife-edges, c c, all arranged and adapted to operate schematielly es and for the purposes described.
2. In combination with the female die or clinchingtoolC, the mole .punch or setting tool D, provided with the concave recesed, and an inclined annular enriece surrounding the purposes described.
