DIES FOR APPLYING COVERING MATERIAL TO THE FACES 0F EYELETS.

SPECIFICATION forming part of Letters Patent No. 789,694, dated May 9, 1905.

Application filed February 9, 1895. Renewed August 23, 1902. Serial No. 120,856.

To all whom, it may concern/.-

Be it known that T, ELEAZER KEMPsHALL, of Sharon, county of Norfolk, State of Massachusetts, have invented an Improvement in Dies for Applying Covering Material to the Faces of Eyelets, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to eyelets for boots, shoes, and other articles, the object of my invention being to provide a novel apparatus for pressing a covering material or substance upon and beneath the face flanges or lips of the eyelets.

An apparatus embodying my invention contains at least two dies, one of which is adapted to hold the eyelet and the other to press the covering material thereupon.

One of the novel features of the apparatus embodying my invention is a support on the eyelet-holding die for the face flange or lip of the eyelet, and over which said face flange or lip projects, to leave a space beneath and surrounding the edge of the same, into which space the covering material may be pressed, and thereby perfectly inclose or cover said flange or lip.

Another feature of an apparatus embodying my invention consists in providing the pressure-die with a depending portion of a size preferably to fit the smallest diameter of the eyelet-shank, but leaving a sufficient space between the said portion and the wall of the recess in the eyelet-holding die to receive the shank or body of the eyelet, the purpose of said depending portion being to enter or, it may be, pass through the eyelet shank or body and work or wipe the covering material smoothly and nicely down to and upon the metal at the interior of the eyelet or its shank or body.

In the drawings, Figure 1, in vertical section, shows a pair of dies constituting part of an apparatus embodying my invention, the eyelet being shown in position, with the covering material indicated in dotted lines above it. Fig. 2 is a similar view showing the two series of seats or supports for eyelet-shanks;

and Figs. 4: and 5, a side elevation and vertical section, respectively, of an eyelet covered by means of the dies shown.

I will firstdescribe one form of apparatus as embodying my invention, and, referring to the drawings, A and B are two dies, which I shall hereinafter designate, respectively, as eyelet-holding and pressure dies.

The eyelet-holding die A is provided with one or more, preferably a series of, holes a, the tops of which are formed within a separate face-piece a, shown as let into the face of the die A, but, in effect, forming a part of the die A and as such will be hereinafter designated. The face-piece a has one or more holes or recesses a registering with the holes a in the die A, and surrounding the preferably flaring entrance to the several holes in the face-piece a are the supports a for sustaining the eyelets, said supports elevating the eyelets to leave clear spaces between their respective face flanges or lips and the subjacent face of the face-piece a, said supports being herein shown as raised above the surrounding surfaces a, which latter preferably constitute the bottoms of as many ring-like or annular depressions or recesses a concentric with and surrounding the entrance to the said holes (6 v The pressure-die B is shown as provided with one or more depending portions 6, for the best results made somewhat tapering or conical at their ends, as shown, there being one depending portion for each hole a, each depending portion being of a size to fit the smallest diameter of the eyelet and enough smaller than the surrounding hole of the die A to leave an intervening space between it and the depending portion for the reception of the body or shank of the eyelet, each de pending portion at its base being surrounded by a preferably concentric ring-like cutting edge or shoulder 1), between which and the base of said portion is the cu p-shaped and annular depression Z2 of a shape corresponding to thecontour desired for the face of the eyelet when completed and covered.

The dies are guided in their movements toward and from each other by usual pins c, which bring the working parts of the dies always in proper registering positions.

In operating the dies the eyelets e, preferably of a shape substantially as shown in Fig. 1 and provided at their tops with suitable face flanges or lips e, are placed with their shanks or bodies in the holes a of the die A with their face-flanges resting upon the su pports (0 the ed es of the said flanges, however, projecting over the said supports sufficiently to leave a clear space beneath and around their edges within the depression a.

The covering material, preferably some plastic materialsuch, for example, as celluloid-and which may be in the form of a strip f, (shown in dotted lines, Figs. 1, 2, and 3,) is

- laid above the flanges of the eyelets in the holding-die A, covering the eyelets and the depressions surrounding the same.

Celluloid and others of the so-callcd plastic materials are normally in a relatively hard or stiff condition, they being commonly rendered plastic for the purpose of working or molding by the application of heat, and for this purpose prior to the filing of this application for patent it has been my custom to place both dies A and B, the former filled with eyelets, upon a steam-heated table until sufficiently heated, when the covering material f is placed upon the eyelets. The heated die B is then taken from the steam-table and placed in working position, as shown in Fig. 1, and the heat renders the covering material plastic, enabling the latter to be freely molded by the pressure-die B. As the die B descends its depending portions 6 first act upon the plastic covering material f and easily pass through the same and enter the eyelets, the ring-like cutting edges 6 acting upon the said plastic covering material and cutting the same to form as many disks or washers of a diameter substantially that of the depressions a, into which said 'disks or washers are forced. The depending portions 6 center or position the plastic washers, and the cup-shaped depressions 6 immediately thereafter press or force the surplus material into the depressions a surrounding and beneath the edges of the face flanges or lips of the eyelets, thus completely covering or inclosing the same. The edges Z) cooperate with the edges of the depressions (b in forming the peripheral edges of the disks or washers, and by seating firmly upon the bottoms of the depressions the said edges thereafter operate to form clean peripheral edges to the coverings for the eyelets. The depending portions 5, which first enterthe shanks of the eyelets in the dies herein Shown, reach the bottom of the smallest diameter of the said shanks by the time the edges 6 act upon and force the then ring-like covering material into the depressions of so that the bringing of the two dies together causes the plastic covering material to be not only tightly compressed about the face-flanges of the eyelets, but also by means of the depending portions the said covering material is worked or tapered down to the material of the interior of the eyelet shanks or bodies, leaving when the depending portions are removed cleanly-finished edges which in no way obstruct the open center of the eyelet.

I do not herein claim the particular form'of eyelet with the covering material applied thereto, as the same forms the subject-matter of United States Letters Patent No. 557,992, granted to me April 7, 1896.

So far as known to me, I am the first to rest the face flange or lip of the eyelet upon a support at the entrance to the shank-receiving opening of the die, leaving the said face flange or lip to project over the support in order to leave a space around and beneath its edge to be subsequently filled by the plastic covering material, my invention thus providing for a continuous clenching-lip of covering material turned inwardly under the face-flange.

I believe that I am also the first to devise an apparatus comprising means for supporting an eyelet with its head exposed and meansfor applying covering material to both sides of the head. I believe, further, that I am the first to employ in such an apparatus means to enter the hole in the flange of an eyelet for applying covering material within the flange of the eyelet or for determining the extent to which the covering material shall extend into the interior of the eyelet.

While some features of my invention are limited to devices forcovering eyelets having central lacing-passages, it should be understood that other features of the invention may advantageously be employed in devices for applying covering material to lacing-hooks or other similar articles, and therefore the word eyelet wherever occuring in the specification or claims should when the context permits be construed as including eyelets, lacinghooks, and other similar articles.
