HoLLoW RIVET;
Application filed .Tulyl l. 1925." Serial N al -43,573.
This invention relates to hollow rivets, specially designed for fastening papers or paper documents, of. the well known Challenge eyelet type, which arevinanufactured under the patentto E. L. Sibley, No. 358,225,
dated February 22, 1887, and ordinarily manufactured from a radiate blank snchasshown in that patent or aradiate blank such as shown in the patent of E. L. Sibley, 2nd;
No. 1,469,757, dated October 2,1923, both r these blanks having flange-forming terminals projecting from opposite, tl iat is to say, both edges of the radiating fingers or sections and involvingsome waste of material in the manufacture of the hollow rivets.
present invention by the patentee of Patent, N'o,'1,469,757, above mentioned, con- The sists of a radiate blank having four fingers or sections,the flange forming ends of which are extended laterally from one edge,.pref
erably the rightside edge, only of these fin gers or sections, thereby effecting economy in production without impairing the operation or usefulness of the'hollow rivet, as I will claim.
proceed now to explain and finally In the accompanying drawings, illus I trating the invention, in the several figures of which like parts are similarly designated Figure 1 is a plan view of the blank from which the hollow rivet shown in Figs. 3 and 4 is made. Fig. 2 is an edge'view ofthe blank. Fig. 3 is a top plan view of a hollow rivet formed from theblank shown in Figs.
1 and 2. Fig. l is an elevation of said hollow rivet. l
Obviously, all of the views are greatly exaggerated over the norinal'size of the hol-' low rivets.
Referring to Figs. 3 and 4:, the FChallenge eyelet of this invention and of the inventions'of the patents referred to, comprises a closed driving head 1, a barrel 2 and a base fiange'3.
The device of this invention having these parts is forined from the blank of Fig; 1, which has'the four fingers or sections radi= ating from a solid center 5, these fingers or sections having lateral projections 6 extendl ingfrom one edge only, preferably the right hand side edge, and having an arcuate'outer surface 7 and a straight innerfsurface 8;-
. The oppssite aide or back ,3 cf the 7 sections with the lateral terminal extensions from one edge only lends tself mostreadily fingers or, sections.
gers or sect ons is made straight from center to outer end. The fingers or sections 2 of the device. the center 5 forms the driving head 1 of the device, and the ends of the fingers or sections having the 'one-edgeflateral projections form'the flange 3 of the dc vice; The blank, by means of suitable tools or machinery, is drawn into the shape of the l form the barrel device, the 'fiat fingers or sections being curved transversely in the arcs of circles, to form the cylindrical barrel, or they maybe otherwise'shaped to form the desired configuration, the cylindrical barrel and the circular flange being of the usual conventional shape.
In the formation of the'flange 3, the ends of the fingers or'sections'arebent at right angles to the main portions of the fingers or' sections, and the straight inner surface 8 of the projection 6 will lie against the end ofthe straight back 9 of the finger or section next to it, as indicated in Fig. 3, so that the circularity and continuity of the flange are-unbroken.
VVhile'the blankhaving four fingers or to economical production, it isto be understood that the invention is also applicable to blanks-having agreater or less number of i 7 Variations in the details of construction are permissible within the principleof the t invention and lowingq'" Whatl claim is thescope of the claims fol- 1. A hollow rivet, having fingers provided I with lateral end proiections extending from terms-:1 er? fear fingers, cf fitilti' extending from one edge thereof only and having an areuate outer surfaceand a straight inner surface, the back of the fin gers bemg strzught.
5. A hollow IlVQt havlng-a barrel and a flange formed of four fingers, each of sard fingers havlng at lts outer end a prqectron extending from one edge thereof only and having an arcuute outer surface and a 10 straight inner surface, the back of the fingers beingstraight; the straight back fitting the straight inner surfaceofthe end of the ad- ]acent finger 1n the fornmtlon of the flange.
