THICK EDGE TACK FASTENED BUTTON Filed Sept. 5, 1951 Patented Jan.. y19, 1932 PAUL FENTON', OF THOMASTON, GEORGE A. KING, 0F WATERBURY, CONNECTI- CUT, ASSGNORS TO SCOVILL I/IANUFAGTURNG- COMPANY, OF WATERBURYCON- NECTICUT, A CORPORATION OF CONNECTICUT l Application filed September 5, 1931. Serial No. 561,449.

The object of this invention is to provide a light-weight metal button having a thick edge Y so as to conform to standard buttons, and the button as herein shown and described is of the type in which a tack is used for setting it although the thick edge feature may be einployed in other` types of buttons.

rlhe invention consists of a button having a back made of thin sheet metal, such as aluminum, wherein a groove is made in the edge to which the face or cap is secured and when so secured the edge or periphery of the button is relatively thick so as more securely to retain engagement with a button holle or other part with which the button is engaged, as we will proceed now more fully to'explain and finally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure l isa bottom plan view; Fig. 2 is a top plan view, and Fig. 3 is a cross-section of the back. Fig. l is a top plan view; Fig. 5 is a bottom plan view, and Fig. 6 is a side elevation of one form of anvil that may be einployed. n Fig. 7 is an enlarged cross-section of the finished button. Fig. 8 is a cross-section, enlarged, of the finished button mounted upon an object, with the setting tack shown in elevation.

The back l of the button, is made lof 4thin sheet metal, such as aluminum, and provided with a hub 2 having a hole 3 and a ange or collet 4 extending laterally from the hub and having its edge provided with a groove 5 with its outside or peripheral edge 6 flared outwardly. The top of the ange or collet between the hub 2 and the groove 5 is fiat and level with the edge 6y and the top of the hub and the inside of the afterrnentioned cap or face to support the latter.

The cap or face 7 likewise may be made of thin sheet metahand it is provided with the flange 8 to be closed upon the grooved edge of the back. p

YAny suitable anvilY may be used, but it is preferred to employ one madeof relatively7 thick hard metal, such as steel7 so as to turn or clinch the point of the ,setting tack without liability of puncturing the cap or face.

Such an anvil isfshown in Figs. l to 8, and

consists ofa hollow cylindrical body 9 having a flat and angeless top10 to form the tack point-turning feature, and Athebottorn yturned in to forman open-endedpart llV to anchor the clinched tack in the anvil. Y

rl`his anvil is placed in the hub with its top on a level with the adjacent flat part of `the flange or collet, so that when the cap or face is applied to the back its adjacent partscwill lie flat and be supported upon the fiat toplof the anvil back.

is shown in Figs. 7 and 8 the bottom of the anvil rests upon the bottom of the hub, al?

though it may extend shortlyabove it.

The hole in the hub and the open end in the anvil register when the parts are assembled, as shown in F igs. 7 and 8, so that the setting tacks pointed shank may enter the button and be upset or clinched against the top of the anvil and anchored against the bottom'of the anvil and thus afford a secure connection of the tack and button, as indicated in Fig. 8.

In Fig. 8 the part i2 may be a portion of a garment or other article to which the button is fastened, the button being arranged on one side thereof and thetack 13 driven through it from the opposite side into and clinched within the button as explained.

The provision of the groove in the back or collet and the closing thereonof the flange of the capor face, aords a thick-edged button which is desirable for the reasons above stated and also to afford a desirable finish.

Variations in the details of construction vare permissible within the principle of the invention and the claims following.

Vhat we claim is l. A button, having a back provided with a hub having a laterally extending flange or collet and a peripheral groove and a flat portion between said hub and groove, acap having a flange closed down upon the back outside of its grooved flange and flat portion and resting upon these parts, and an anvil arranged inthe hub and flush with the inner side of the. cap and adapted to receive and clinch an attaching device. I

2. A button, having a back provided with and the contiguous flat parts of the a huh having a laterally extending flange or collet and a peripheral groove and a flat portion between said huh and groove7 a cap having a flange closed down upon the hack outside of its grooved flange and porion and resting upon said parts, and an anvil arranged in the huh and Hush with the inner side of' the cap and adapted to receive and clinch an atta-ching' device, the hack ard cap being niade of thin inet-al ani *che anvil being' made of relativeb7 thick and hard inelal.

3. A button, having a hack confusrisinga hub having` a flange or colle?J and a peripheral groove therein, said flange extending laterallv from the top of the hub and on a, level With said top and flat 'between the hub and said groove, said groove having` an out' rdly flared edge surroundingsaid portion, a flanged ca p closed down upon the flat portion and about the edge of he groove and supported thereon, and a cylindrical anvil fitted within the hub and liifivirre` a closed flangeless flat top on which *ehe cap reste.

In testimonjyY whereof We have hereunto eef our hands this 4th day of September, A. D. 1931.
