DEVICE FOR FEEDING EYELETS OR SIMILAR OBJECTS.

SPECIFICATION forming part of Letters Patent N o. 568,201, dated September 22, 18916.

Application filed December 10, 1895. Serial No. 571,681.

To all whom t may concer/L.-

Be it known that I, ALBERTLATHAM, a citizen of the United States of America, and a resident of Springfield, Hampden county, State of Massachusetts, have invented certain new and useful Improvements in Devices for Feeding Eyelets or Similar Objects,

of which the following is a specication.

It is well known that in the art of covering and forming the tops or heads of eyeletsby the employment of a plastic material, such as pyroxylin, two dies are employed, one of which is known as the eyelet-receiving die and the other as the covering and head-forming die.

This invention relates to improved means for feeding or supplying eyelets from the mass with their stems or shanks in the sockets for such shanks of the receiving-die, (which die in practice has multiple series of the shank-receiving sockets.)

The invention and mode of utilization thereof are fully and clearly illustrated in the accompanying drawings, in which are shown two plates employed in the feeding or transferring operation separately and in their cooperative combination with each other, and the one thereof in its coaction with the receiving-die.

Figure l isaplan view of the iirst transferplate, with, annexed thereto, a longitudinal section of the same. Fig. 2 is a plan view of the second transfer-plate7 with, annexed thereto, a longitudinal section ofthe same. Fig. 3 is a sectional view of the first plate, the same being shown as filled with eyelets. Fig. 4 is a sectional view similar to Fig. 3, with the first plate superimposed by the second plate. Fig. 5 is a sectional view of the second plate inverted from its position shown in Fig. 4, with the eyelets sunk within the pockets thereof. Fig. 6 is a sectional view of the second transfer-plate superim posed by the eyelet-receiving die-plate. Fig. 7 shows the die inverted from the position shown in Fig. 6, the eyelets being transferred thereinto. Figs. 8 and 9 are sectional views illustrating modifications in the form of the pockets in the second transfer-plate. Fig. lO is a sectional view hereinafter referredvto.

(No model.)

Similar characters of reference indicate corresponding parts in all of the views.

The first (feeding) plate (represented by the reference-figure l) has therein a series of holes or sockets a, of a diameter to allow the shanks of the eyelets to settle easily thereinto without binding, the orifices of the said holes being preferably iiaring.

The second (transferring) plate (represented by the reference-gure 2) has a series of pockets b, in number and arrangement corresponding to the holes in the iirst plate l, but these pockets are of such diameter as to allow the head of the eyelet to freely drop thereinto, and the depth of thepockets (which essentially have bottoms) are, by preference, as great as the length of the eyelets.` i

O represents the eyelet-receiving member -of the set of covering-dies, which is understood to have a multiple series of eyelet-receiving sockets c, in number and arrangement corresponding to the holes and pockets in the feeding and transferring plates l 2.

The plates l and 2 have the one thereof the corner or marginal dowels d ol and the center dowel g, which is longer than the corner dowels, while the other plate has the matching holes d2 d2 and g2.

Eyelets in the mass or indefinite quantity received upon feeding-plate l by agitation settle into the sockets a, filling all the latter. (See Fig. 3.)

Transferring-plate 2 is matched with and superimposed on plate l, as seen in Fig. 4. Then the two plates are inverted and plate l is removed, leaving all the eyelets which had fallen head downward in the pockets of plate 2. (See Fig. 5.) The receiving one, O, of the set of covering-dies is now matched with and overlaid upon plate 2, as seen in Fig. 6. Then the said die member O and plate 2 are both inverted and plate 2 removed, leaving all the eyelets which had been head inward in plate 2 in the receiving-sockets therefor of the one member of the set of covering-dies.

In practice in the employment of the transfer-plates preparatory to introducing the eyelets into the dies C the eyelets are received shanks upward andsunk within the upper surface of plate 2, and a number of these IOO plates are stacked up one upon another near the hand who separates the covering-dies, the pocketed eyelets being protected against injury Which might arise from exposure, and a great many of the plates, by occupying each a comparatively slight height, may be piled in a single stack.

By providing one of the plates l or 2 with the short marginal dowcls and with the longer center dowel the matching of the plates in the transferring operation is facilitated by bringing the center dowel of the one plate far into the central socket therefor of the other plate, and the first plate may be most readily swung horizontally until the shorter pins come to and settle into their sockets.

By having the base of each pocket b made conical, as seen at h, Fig. 8, the eyelets or annular objects may be centered,7 so that with very loose pockets b the eyelets may more readily and centrally find their way into the die-sockets. The pockets b at their bases maybe undercut, as seen at j in Fig. 0,wherebythe retention of the eyelets in the sockets b will be assured despite careless handling and unnecessary rocking of the transferplates 2.

For the purpose of brevity the term eyelet has been herein uniformly employed 5 but it is understood that the means to be patented may be successfully used in feeding into dies other circular articles than eyelets, such, for instance, as lacing-studs and certain kinds of buttons, and in Fig. l0 a utilization of pocketed plate 2 is shown in combination with an eyelet-covering die D, the plate 2 receiving in the pockets thereof celluloid or other plastic washers m for covering, which it transfers onto the stud-like projections of the covering-die D.

I claiml. The combination with a plate, l, having a series of sockets of a size to receive the shanks only of headed objects as eyelets, of a second plate having a series of pockets corresponding in arrangement to the sockets, but of a size to receive therewithin the heads or enlargements of the objects to be fed substantially as and for the purpose set forth.

2. A plate, 2, having a series of pockets, Z9, with bottoms, to receive bodily therewithin circular or annular objects, in combination with a die constructed to receive said objects as transferred thereto from the pockets of the plate, substantially as described.

3. A transferring-plate having a series of pockets or recesses each of which is adapted to receive and contain the enlarged end of an eyelet, and each being so constructed that the eyelet is held against accidental displacement in the careless handling of the plate, substantially as described.

4. The transfer-plate, 2, having the series of pockets therein, the walls of which are undercut next to the bases thereof, substantially as described.

In testimony that l claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 9th day of December, 1895.

ALBERT LATHAM.
