HERMAN G. WEIBEZAHL, OF NEW YORK, N. Y.

EYELET.

SPECIFICATION formingpart of Letters Patent No. 698,770, dated April 29, 1902. Application filed $eptember 11,1901. Serial No. 75 ,021. (No model.)

To all whom, it rnctg concern.-

Be it known that LHERMAN G. WEIBEZAHL, a citizen of the United States, and a resident of the borough of Manhattamcity, county,and State of New York, have invented certain new and useful Improvements in Eyelets; and I hereby declare the following, taken in con junction with the accompanying drawings, to be a full, clear, and exact description of same.

The subject of the present invention is an improved eyelet for fastening together thicknesses of paper or other material, and has for its primary object the production ofan article of a class referred to which when set will in addition to its normal flange at one end present at the other a head formed by the laterally-spread metal eifected by the compression sustained during the setting operation.

To this end the invention consists in part of an eyelet having a normal base-flange and with the metal at the other open end so strengthened that when the eyelet is compressed in the setting operation such stronger metal portion will cause the weaker metal contiguous thereto to spread laterally and present a highly satisfactory head.

There are other novel features connected with my invention which are fully disclosedhereinafter.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan view, on an exaggerated scale, of a blankindieating the partial formation. of one form of eyelet embodying my invention. Fig. 2 is a vertical elevation of the eyelet completed from the blank illustrated in Fig. 1. Fig. 3 presents a top view of the eyelet before being crushed, while Fig. 4: illustrates the same when crushed, showing the head formed by the laterally-spread barrel. Fig. 5 represents my eyelet in two positions, partially set and completely set in the paper. Both views are shown in section. In Fig. 6 is shown a section of the head of the eyelet, showing in detail the formation of the fortified ring portion constituting the eye of the improvedeyelet. Fig. 7 is a vertical sectional view of another form of eyelet embodying my invention, the slits being omitted and the dotted lines indicating the spread portion forming the head. Fig. 8 is a vertical side elevation of another form of improved slitted eyelet, the portion to form the head being represented as partially spread. Fig. 9 is a vertical sectional view of the form shown in Fig. 8 before being spread. 1 Similar reference characters designate corresponding parts in the several figures.

Referring more particularly to Figs. 1 to 6, the blank from which the eyelet is to be formed is of thin metal and comprises a central portion A, from which extend a series of "radial members B, each terminating in asector-shaped end 0, as indicated in Fig. 1. The metal of the central portion A immediately surrounding the opening A therein is turned over to present an annular curled beading A around the said opening, which constitutes a ring carrying the eye of the eyelet. The members B are bent right-angular to the portion A, with their edges closely adjacent to each other to constitute a barrel B, open at portions of the barrel to cause the latter to collapse and spread outward laterally to form a satisfactory head, as shown in Fig. 4. The outwardly bend of the members composing the-barrel is assured by the pressure of the stronger or doubled'portion of the beading forming the eye; but an anvil on springs upon which theeyelet is designed to be set makes the collapsing inwardly of the members an impossibility.

In Fig. 7 the barrel and its flange are unslitted, the stronger metal'at the other open end being secured by contracting. the eyelet to obtain a tapering portion D. This is done in the drawing process,the barrel being drawn relatively thinner than the tapering portion, as shown, which is not crimped or otherwise weakened. The angle at which it is set in relation to the barrel. assures the outward spread of the latter.

Figs. 8 and 9 illustrate the arrangement for securing the stronger metal at the end where the head is to be formed, the same as in Fig. 7, the barrel being provided with slits E, which do not extend to the normal flange of the eyelet.

As-thus explained, it will be appreciated that an eyelet produced in accordance with my invention can be quickly and efficiently applied and set and can be made and sold in quantities at a cost comparing favorably with other types now in use, while presenting advantages possessed by no others.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An eyelet comprising segmental arms constituting thencrmal flange and the barrel of the eyelet, with a partially-closed and stronger upper portion constituting its end.

2. An eyelet, the barrel of which has at one of its open ends an inwardly-extending and immediately contiguous flange, the said barrel weaker than the said flange, and anorinal base extending outwardly from the said barrel. 1

3. -An eyelet presenting a normal flange at one of its open ends, and constituting the base, the upper end of the eyelet presenting the eye and a flange stronger than the metal of the barrel immediately contiguous thereto, said stronger upper portion capable, upon compression, of causing the metal of the barrel to collapse.

4. An eyelet, the barrel of whichhas at one of its open ends an inwardly-extending flange,

the metal of said barrel immediately contigu stronger metal portion than the barrel im me diately contiguous thereto and capable of spreading the said slitted barrel outwardly upon compression, and form a head. v

6. A sheet-metal eyelet comprising members terminating in sector-shaped ends with a central portion perforated to form, with its surrounding metal, the upper end of the eyelet; the said members forming a barrel with a normal flange presented by the sector-shaped ends, the said upper end of the eyelet involving a-stronger metal portion than the immediately-contiguous barrel which, weakened.

by the slits, and spread outwardly by com eye being stronger than the barrel metal immediately contiguous thereto.

8. An eyelet having a heading around one of the open ends of the barrel, said beading designed to render the metal stronger thereat and adapted, when subjected to compression, to spread the contiguous weaker metal of the barrel to form ahead.

9. An eyelet having a normal flange at one end of its barrel and a beading around the other open end thereof, said beading rendering the metal stronger thereat and adapted, when subjected to compression, to spread the contiguous weaker metal of the barrel toform a head.

10. An eyelet'with a slitted barrel and a beading around the upper end thereof, said beading rendering the metal stronger thereat,

and adapted, when subjected to compression, to spread the contiguous slitted and consequently weaker metal of the barrel to form the head.

11. An eyelethavinga normal flange at one end of a slitted barrel and a beading around the other open end thereof, said beading rendering the metal stronger thereat and adapted, when subjected to compression, to spread the contiguous slitted and consequently weaker metal of the barrel to form the head.

12. An eyelet stamped out of sheet metal and pressed into a barrel, open at both ends,- one of the said ends equipped with a heading around the same formed of the metal displaced to form the .eye, the said beading designed to cause the barrel to spread outward in those portions .of the eyelet extending" above the material to be fastened together,

7 and form a broad bearin g against the said material. I p

13. An eyelet stamped out of sheet'metal and formed into a barrel with a flange at one of its open ends and a beading formed by the metal displaced to constitute the other open end, the said beading designed to cause the barrel to spread outward in those portions of the eyelet extending beyond the material to be fastened together, and form a broad bear-
