BUTTON.

Application led .Tune '24, 1922.

To all whm t may concern Be it known that LFORREST G. PUmN'roN, a citizen of the {United States, and a resident of Vaterbury, in the county of New Haven and State of Connecticut, have made and invented certain new and useful Improvements in Buttons, of which the following is a specification.

My invention relates to buttons and particularly to that class or type thereof which are secured to garments or other material by means of a metallic fastener. Buttons of this class, and particularly when made of metal, have heretofore been formed from sheet metal which is stamped and pressed to shape and normally composed of a body, in

which is positioned a separately formed die or anchor and a separately formed anvil, the button accordingly being composed of several arts and thus requiring a considerable num er of operations in its make-up and the final assemblage of the various parts in their proper relation.

It is the object of the present invention to forma button possessing all of the advantages and characteristics of the assembled button as above outlined, and, further, pos-I sessing the very desirable feature of being formed entirely of one piece of metal, so that the buttons may be produced in large quanti-ties at a very low cost.

A further object is to accomplish the aforementioned ends and provide a button made of a single piece of material or metal which will contain or possess the usual head and hub and with the hub so formed as to contain a recess having a restricted opening leading therein which thus takes the place of the usual separately formed anchor, and extending above the anchor chamber or recess is sufficient metal so as to form an anvil, preventing the distortion of the anchor chamber and surrounding metal as the metallic fastener or tack is driven into place and upset therein.

A further object is to provide a novel method of button formation whereby a single-piece button is provided and capable of being attached to a garment or-other material by an automatic button attaching machine and secured in place by the customary tack fastener.

A further object is to provide a button as above outlined and having in addition a top plate which may be suitably ornamented or Serial No. 570,656.

will be obvious to those skilled in the art to which my invention relates, it being understood that changes may be made within the.

scope of what is claimed from the spirit thereof.

In the accompanying drawing: Figure l is aview in elevation of the rod without departing ,or Wire from which my novel button is formed;

Figure 2 is a View of the first operation blank;

Figure 3 is a view in vertical section of the bla-nk showing the third step of the process and illustrating the blank with the tackreceiving chamber being formed therein;

Figure 4 is asimilar View showing the completed butt-on and with the entrance to the tack-receiving chamber partially closed;

Figure 5 is a view in vertical section of my novel button, the same being provided with an ornamental top or cap;

Figure 6 is a view in vertical section of myv improved button formed by a modification of the above-mentioned process, the blank as shown in Fi ure 3 having the lower ends of the hub sweged or rolled inwardly;

Figure 7 is a similar view showing this particular type of button having an ornamental top or cap; and

Figure 8 is a view in vertical section ofmy novel button showing the same attached or secured to a garment or other material.

Referring specifically to the several views, wherein similar reference numerals designate corresponding parts throughout, the rod 10 represents a conventional form of Wire such as used for example in heading machines for the formation of rivets and may be made of steel, brass, aluminum or any other desired material possessing the necessary properties for heading operations. The wire is fed into an automatic heading machine (not shown) and automatically cut line A and this preliminary blank is then aut'on'iatically moved into the path of suitable heading dies (not shown) and swedged to length as illustrated by the dot and dash or headed so as to form the first step button 4blank illustrated in Figure 2, which is composed of a headll and a solid shank 12. This irst step blank is then subjected to the action of a second set of dies (not shown) and the shank provided with a suitable recess or chamber 13, as shown in Figure 3. This second step blank, as shown in Figure 3, is then subjected to the action of another Set of dies' and the bottom Wall 14 of the shank is swedged inwardly as at and in so doing compresses or draws to ether the ends 0f the side walls of the cham er 13 and thus v provides a restricted opening 16 leading into the tack-receiving chamber 17.

The finished button as illustrated in Figure 4 is accordingly' composed of a head 18, corresponding to the head 11 of the original blank; further, possesses va hub 19 of approximately the size of the shank 12 of the first-step blank, and, further, contains a tack or fastening-receiving chamber 17 having a restricted opening 16 leading thereinto, so that when the prong of the tack or fastener is forcibly driven int-o the receiving chamber 17 and headed therein it will be prevented from being withdrawn therefrom. Further suiiicient metal is provided as at 19 and extending directly above the fastening-receiving chamber 17 so as to prevent thel button from being distorted as the fastener Vis being upset therein.

The single-piece button as thus formed possesses all of the advantages and characteristics of the assembled button as heretofore made up of three or more parts; and` further, requiring considerably fewer operations in its manufacture, entailing no scrap whatever, and, being made from rod or bar material, may be much more economically manufactured. Further, I am able to make the buttons of aluminum, brass, steel, or any other composition susceptible to headin operations. Attention is also called to the fact that the restricted opening 16 has downwardly and outwardly tapering side walls so as to guide the point of the tack fastener into the tack-receiving chamber 17.

Should it be desired to pro-vide the button with an ornamental cap, this may be readily accomplished as illust-rated in Figure 5,

wherein thel head 18 has pressed thereon an ornamental top 20, the same extending down over the edges of the top and flanged or bent thereagainst, as at 21. The ornamental top may be suitably inscribed or possess any desired ornamental finish consistent with the purpose for which the button is to be used.

The somewhat modified form of process and button produced thereby as illust-rated in Figure 6 starts with the second sta-ge blank as illustrated in Figure 3 and has i nasser? the lower end of the side walls of the shank` 12 swedged or inwardly rolled so as to form' the indentation 22 slightly above the bottom Wall 23 of the hub and which inward rolling and indenting of the side Walls of the shank causes the lower ends of the vwalls of the chamber 13 to be forced inwardly to form the restricted opening 24 and thereby form a fastener-receiving chamber 25. The but-ton as thus produced is in many respects similar to the button as illustrated in Figurev 4 and possesses all of the desirable advantages and features thereof. The button as shown in Figure 6v may also be provided with an ornamental top or capas illustrated in Figure 7, wherein the head 26 of the 'button is provided with the cap 27 embracing the same and secured thereto, and which cap may be suitably ornamented, embossed or inscribed in any desirable manner.

1n Figure 8 I have illustrated my novel button as produced by my novel process and attached to the. garment or other material 28, by a suitable tack fastener 29 having its shank or prong 30 forcibly driven through the garment material and with the point 31 forcibly upset and curled upon itself within the tack-receiving chamber 25, thus permanently attaching the button to the garment material.

Having thus described and explained my invention, I claim and desire to secure by Letters Patent:

1. A button composed of a body formed of a single piece. of metal, said body having an enlarged head, a hub forme-d integrally therewith, said hub having an enlarged fastener-receiving chamber formed therein, a restricted opening leading into said fastener-receiving chamber, the side walls of said restricted opening being downwardly an'd outwardly tapered so as to guide the point of a fastener into the fastener-receiving chamber.

2. A button composed of a single piece of metal formed from bar stock and comprising an outwardly flared head, a hub projecting therebelow and formed integrally therewith, said hub provided with an enlarged fastener-receiving chamber having a restricted opening leading therein, sufficient metal located above said chamber to form an anvil for upsetting the point of a fastener thereagainst, and an ornamental top carried b v the head of said but-ton.

Signed at Waterbury, in the county of New Haven and State of Connecticut, this 22nd day of June A. D. 1922.

FORREST GRANVILLE PURINTON.
