EYELET.

SPECIFICATION forming part of Letters Patent No. 708,577, dated September 9, 1902.

Application filed February 8, 1902. Serial No. 93,195. (No model.)

To all whom it' may concern:

Be it known that I, GEORGE E. MCCORMACK, a. citizen of the United States, residing in East Bridgewater, in the county of Plymouth and State of Massachusetts, have invented a certain new and usefullmprovement in Eyelets, of which the following is a specification.

This invention relates to eyelets made,pref erably, of sheet metal and of the class which are provided with setting flanges or heads, such eyelets being used principally, but not necessarily exclusively, in connection with leather boots and shoes; and the invention has for its object to provide an eyelet which while light in weight has a flange which is heavy in proportion to the band and very strong and stiff, so that the band can easily spread under the pressure of the setting-tools without any yielding or deformation of or injury to the flange and whereby the paint or enamel cannot easily crack olf from the flange.

My present invention comprises an eyelet the flange of which consists of two thicknesses or layers of metal, said thicknesses 'bein g folded against each other, so that the under thickness is in actual contact for its entire width and length with the upper thickness, the two thicknesses or layers being concavoconvex in cross-section and concentric and with their grooved or hollow portion facing downward and the under layer being preferably thicker or heavier than the upper layer, all as fully described below,and illustrated in the accompanying drawings, in Which- Figures I to 6, inclusive, are transverse vertical sections illustrating the different steps in the method by which my improved eyelet is preferably constructed Vfrom the blank. Fig. 7 is a similar section of the complete eyelet embodying my invention. In each of these figures the eyelet is shown on an enlarged scale, Figs. l to 6, inclusive, showing it as on a scale about one-half the size of' the scale indicated in Fig. 7.

To form the eyelet, a cup, substantially as illustrated in Fig. l, is made from a round blank, and from this cup the form illustrated in Fig. 2 is constructed, the upper part of which shows the beginning of aflange. This flange is then turned down into the shape indicated in Fig. 3 and then inward into the shape indicated in Fig. 4, in which the flange comprises two thicknesses of the instal. The barrel is then drawn in slightly and the ange rolled, as shown in Fig. 5, and the barrel is then pierced, as shown in Fig. 6. In Fig. 7 the device is complete and shows the barrel A tapered or growing thinner toward its lower end and with its upper portion spreading into a flange,which consists of the upper layer or thickness B and the lower layer or thickness B. The lower layer is somewhat thicker than the upper layer, is in contact with it throughout its entire length and Width, and the flange thus constructed is concave-convex in crosssection and with its concave or hollow side facing downward. This flange is not only relatively heavy as compared with the barrehbut is by reason of its shape exceedingly strong and stiff, so that the enamel or paint applied to the flange will not bein danger of cracking off. Moreover,when the eyelet is applied the flange is reinforced or strengthened, for the reason that the leather, cloth, or other material in whichlthe eyelet is used fills up the groove or cavity under the flange. The barrel, especially the lower portion of it, is relatively thin, and hence can be easily spread under the pressure of the setting-toolls,while\ the thickness and stiffness of the flange prevent its being forced out of shape.

While the method above described may be the preferable one, yet I do not desire to confine myself to such method in all or any of its steps.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is#

The herein-described improved sheet-metal eyelet, comprising the barrel A, and the circular flange consisting of two thicknesses or layers of metal B, B', concentric in cross-section and in physical contact with each other throughout their entire width and circumference or length, the peripheral portion B of naine to this specication in the presence of the metal constituting the flange bein g folded two subscribing Witnesses.

under the portion B, and eorrespondino in shape thereto, and the flange being formebd to GEORGE E' MCCORMACK' 5 produce an annular groove on its under sur- Witnesses:

face, substantially as setfonth. LUCY E. OSBORNE,

In testimony whereof I have signed myl G. HOWARD SOULE.
