Specification of Letters Patent.

Patented July a, 1912.

Application filed January 26, 1912. Serial No. 673,521.

To all whom 'it may concern:

Be it known that I, JAMES PIOKLES, a citizen of the United States, residing at Ansonia, in the county of New Haven and State of Connecticut, have invented certain Improvements in Washers, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to improvements in washers and particularly those washers which, in combination with gromets, are intended for setting in sheet material, suchas rubber goods, hammocks, awnings and other textile articles.

An important object of the invention is to provide a washer of such shape that it may be easily and accurately handled in automatic setting machinery.

Heretofore difliculty has been experienced in handling ordinary washers on account of the fact that they are likely to clog a raceway by overlapping. Not only this, but on account of their flat shape and the thin material of which they are constructed, it has been diflicult to separate them at the delivery end. of the raceway and feed them one by one to the setting devices.

In accordance with the presentinvention it is proposed. to provide a washer having. a short rounded barrel projecting from a substantially fiat'flange and it has been found that such washers may be handled'mechani-. cally as conveniently and as accurately as V eyelets or gromets.

Another advantage lncident to the roundedbarrel of the novel washers of this invention is that the washers will not become nested in the hopper but remain separate and pass out through the ports to the raceway in good order. p

In setting washers as heretofore made with gromets much difiiculty has been encountered in locating the washer cent-rally with respect to the setting tool on account ofthe fact that the diameter of the perforation of the washer must necessarily be greater than the diameter of the spindle of the setting die in order to permit the passage of the end' of; the gromet, barrel between the spindle and the inner edge of the washer. This difliculty is avoided in accordance with the present invention by so shaping the barrel of the washer that it will act upon the setting tool, which for this purpose is provided with a locating or centering shoulder, to arrange the washer concentrically with respect to the spindle automatically on its being received by the setting tool. This feature of the washer greatly improves the appearance of the finished work in that the clenched end of the gromet barrel is always disposed concentrically with respect to the washer. Another advantage incident to this self centering or locating feature of the washer is that it permits the employment of a washer having a smaller internal diameter than formerly. In the use of washers and gromets as heretofore set it has always. been necessary to employ washers having an internal diameter considerably greater than the external diameter of the gromet barrel in order to insure roomfor the passage ofthe gromet barrel in case the washer was not arranged concentrically with the setting tool and gromet barrel as was often the case.

Besides improving the appearance of the work the use of a washer having a small opening which fits the gromet barrel results in a stronger and more secure setting as is obvious.

Another object of the invention is to provid'e a Washer which shall present a flat and firm setting surface upon which the end of the gromet barrel may be clenched. Heretofore the end. of the. gromet barrel has been rolled over upon a curved surface formed at the inner edge of the washer. In accord ancewith the present invention, however, it

is proposed to form a flat internal flange at.

the lower edge of the washer barrel upon which the end of the gromet barrel may be rolled or clenched; This arrangement af fords an improvedbearing and holding, for

the clenched'end of the gromet and also perinner edge of the washer.

Another import-ant feature ,ofthe invention results from the fact that the barrel mits a more perfect rolling and clenching of p and inner flange of the washer form in efli'ect a recess in which is contained. the clenched; As a result of end of the grometbarrel. this construction the clenched end 'of the gromet barrel is contained in a space below the plane of the washer instead of, as formerly, projecting above the plane of the Washer. This construction is advantageous because it insures a very smooth setting, the end of the gromet barrel being substantially flush with the surface of the Washer and with the surface of the work. It will therefore be seen that the end of the gromet barrel will not wear into a layer of material in contact with the material in which the gromet and washer are set, as for instance, the tongue of a waterproof shoe, the gromet and Washer being set in the edges of the lacing slit. p

Still another feature of the invention .consists in forming a flattened bead at the edge of the outer flange of the washer. In this way the flange is greatly stiffened and twisting or bending obviated and further, as this extreme edge is oifset below the plane of the .washer, it will be slightly embedded in the work and thus form a neater and tighter joint than has been heretofore possible.

These 'and other features of the, invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings in which,

Figure 1 is a view in perspective of a washer embodying the invention; Fig. 2 is a view in cross section of a washer and gromet set in the work; Figs. 3 and 4 are views in perspective and sectional elevation respectively showing a novel setting tool upon which the washer rests in the setting operation, the tool having a centering or locating shoulder.

Referring to the drawings, it will be seen that the washer-comprises a substantially flat flange 12 having its outer margin offset downwardly to form a bead and its inner edge merging into a short barrel 16. The barrel is somewhat tapering in form and rounded at its end where it merges into a flat inwardly extending flange 18 arranged concentrically with respect to the upper flange 12. 1

In setting a gromet in combination with the novelwasher shown in Fig. 1, the end of the gromet barrel 20 is extended through the work 10 and is rolled outwardly and clenched within the barrel of the washer, engaging the upper surface of the inner washer flange 18.. The barrel 16 and flange 18 of the washer form, in effect, a receptacle in which the clenched portion of the gromet barrel is received. Substantially the entire barrel of the washer is countersunk in the work and its flange lies upon the surface of the work ormay-be slightly countersunk at its edges as shown in Fig. 2. The result is that the -rolled or clenched portion of the gromet barrel 20 lies below the surface of the work and substantially flush with the washer flange 12 so that the general eifect of the work is smooth. Even if the end of the gromet is split in the clenching operation its rough edges are surrounded and kept out of contact with the work by the washer.

In Figs. 3 and 4 there'is shown the upsetting die used to effect the clenching of the gromet barrel and which retains the washer during this operation. The die-has a head 30 from the center of which projects the tapering spindle 34 having at its base a curved clenching surface. When gromet barrel is forced on the spindle 34, it is flared, turned outwardly at its end and rolled over or clenched, as shown in Fig. 2, when it encounters the curved clenching surface. During this operation the washer should be disposed concentrically of the die and spaced at its inner edge from the spindle. This is effected, in using the novel washer of the present invention, by the action ofthe inner tapering surface of the of the head 30 of the upsetting die. It is v necessary only to deliver a washer to the upsetting die whereupon it automaticallycenters itself in a spaced relation to the spindle leaving just suflicient space between the spindle and its inner edge to receive the gromet barrel.

The method of manufacturing the washer of the present invention needs no explanation further than the statement that it may be drawn or struck up from sheet metal by the use of suitable dies in a manner well known and long practised by those skilled in the ,art.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. A washer having a substantially flat flange with its marginal edge offset to form a bead, a short tapering barrel extending from the flange and having a rounded end adapted to sink: into the material in which it is set, and a flat annular flange within the rounded end of, the barrel.

'2. A washer having a substantially flat the flange, a short tapering barrel extending from the flange and having a rounded end adapted to sink into the material in which it is set," anda flat annular flange within the rounded endof the barrel.

3.
