pas i' Wi ri' Patented Jan. 2l, 1930 UNlTE PATNT OFFCE GUT ABEL, OF XVATERVILLE, AND ASSIGNORS T0 THE PATENT CORPORATION 0F CONNECTI- TACK BUTTON Application filed July 16, 1929.

Our invention relates to new and useful improvements in buttons, and more particularly to the type of button known as a tack button.

One of the objects of the present invention is to provide a tack button wherein the button proper consists of simply a shell, an anvil and a cover, the shell, however, being of such form and shape that when the tack is once driven into place, it will hold the button to the cloth in an extremely tight and efficient manner.

Another object of the invention is to provide a tack button wherein the shell is provided with a hub, which hub is slightly enlarged or provided with a ring portion on its bottom to thereby provide a larger contacting area with the cloth than otherwise would be the case.

Still another object of the invention is to provide a tack button wherein the shell is provided with an integrally pressed hub, which tapers from its point of merger with the body of the button down to near the lower edge where it is enlarged to provide a greater contacting area.

Still another object of the invention is to provide a tack button wherein the hub of the shell of the button is constricted or tapered so that when the tack is 'jammed up within the button and mutilated, it will tend to fill up the space at the bottom of the hub and then more tightly grip the button to the cloth.

Still another object of the invention is to provide a tack button with a tapered hub and a slightly enlarged bottom, so that when the button is in the button hole, the lower end of the hub contacts with the sides of the button hole to thus prevent the edges of the button hole from being wedged down between the cloth and the bot-tom surface of the button hub.

With these and other objects in view the invent-ion consists in certain new and novel arrangements and combination of parts, as will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment of the invention,

Serial No. 378,679.

Fig l is a sectional view of the button, a piece of cloth and a tack, the latter about to e inserted;

Fig'. 2 shows two buttons attached to a piece of cloth, one button being in elevation and the other being in section;

Fig. 3 is a sectional view of the shell or body of the button before the head and anvil are assembled therewith;

Fig. l is-a view of an inverted button before the tack has been driven into position;

Fig. 5 is a top plan view of the button, a part being broken away to show the anvil.

At the outset, it might be mentioned that the several views are greatly enlarged for the sake of clearness of illustration.

Referring now more particularly to the several views, there may be seen the shell or body of a button comprising the flat portion l, the upwardly and outwardly extending peripheral rim 2 merging therewith and the centrally depressed hub 3. This hub, it will be noticed, tapers from the point where it merges with the flat portion 1 of the shell down to the point l near its lower end where it is pressed or rimmed outwardly to form.

a ring-like portion 5, thereby providing a relatively large surface to contact with the cloth and to provide space for the mutilated tack prong, about to be mentioned. The bot tom 6 of the hub is closed except for a small prick punch, as at 7, centrally of the bottom surface of the hub.

Now when the bottom 6 is pierced in the making of the button shell, a part of the metal is forced upwardly and inwardly, as at 8, this upwardly pressed metal tending to properly guide the prong 9 of a tack l0 when the latter is forced up into the button hub, as will be shortly described.

As may be seen in F ig. l, there rests within the shell, that is, on the flat portion thereof a small central anvil 12 which is provided with the eXtra metal 13, which latter is dished or concaved so to turn the prong 9 of the tack when the same is driven up within the hub.

After the anvil has been inserted, a cover lll is tightly pressed on the shell of the button and clamped about the previously menico tioned rim 2 of the button shell to thus complete the buttom head.

Buttons of this type are attached by placing a number of button heads in one hopper and a number of tacks in another hopper or' a button attaching machine (not shown) and the button is then fed down to the cloth and properly held while the prong 9 ot the tack is driven upwardly through the cloth and through the bottom sui-tace (i of the hub, it being guided by the upwardly pressed metal 8. The prong then passes through the small prick punch 7, after which it is forced against the dished portion 13 of the anvil 12.

It will be seen that the prong 9 in entering the bottom ot the hub first enlarges the hole or prick punch 7 and then jams up against the anvil where it is turned and guided downwardly against the constricted or tapered sides of the hub and in its mutilated state extends down into the enlarged ring portion at the base of the hub.

Furthermore, as the tack is being jammed down into the bottom of the hub, it engages with the mutilated metal or jagged points about the opening, which has been enlarged by the tack being forced therethrough, and causes these mutilated edges to also be curled backwardly and downwardly into the hub, and in actual practice these metal jagged points become substantially integral with the metal of the mutilated tack prong to thus tightly hold the tack and button head together.

The tack, of course, is provided with the head 11 and it will contact with the bottom surface of the cloth when the button is in its attached position. By rimming or enlarging the bottom of the hub, as heretofore described, it will be seen that there is a rel@ atively large clamping areabetween the tack head and the bottom of the hub of the button.

Furthermore, it will `be seen that even though the lower portion of the hub is enlarged to provide the extra clamping area, still by tapering the hub or constricting it near its lower edge, there is less space to be filled up by the mutilated tack than there would be it the sides of the hub were parallel throughout.

Of course, it is an advantage to entirely till up the hub or the lower portion thereof with the mutilated metal as the button head will thus tend to be more tightly held against the cloth than were this not the case.

Again, by pressing the ring-like portion at the bottom otl the hub and having the metal extend across the hub, there are no flat or square edges on the bottom oi the hub to bite into or tear the cloth.

le are aware that it is old to enlarge the lower surface ot the hub ot' a button by bumping the same, but we have found that when this is done, there is relatively such `little metal in the hub that the hub, instead ot being centrally of the shell, will, after being bumped, exten d at an angle to the Shell or, in other words, will appear as a poorly formed or mutilated button.

It will also be noticed in the present invention that the anvil with its lug tit low within the hub so that a greater portion otl the prong of the tack is mutilated and curled over to fill up the entire lower portion of the hub.

The button is one of great simplicity, the head comprising but three parts plus the tack. At the same time, it is so formed that when once attached, it will be impossible to remove the same accidentally.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is l. A tack button comprising a shell, said shell having an upwardly extending peripheral rim and a hub tapering toward its lower extremity, the said hub provided with a ring portion at its lower extremity, an anvil in said shell and terminating above the said ring portion, a cover over said anvil and the rim ot said shell and the said anvil adapted to turn the prong of a tack downwardly and into the ring portion of said hub.

2. A tack button comprising a shell, said shell having an upwardly extending peripheral rim, an integral hub on said shell and tapering toward its lower extremity, the said hub being flared at its lower extremity and the metal extending from the tiared portion across the bottom of the hub, the said metal extending upwardly and the same being slightly pierced, an anvil in said shell and the lower portion ot the anvil terminating above the flared portion of the hub, a cover over said shell and the said anvil adapted to jam the prong of a tack downwardly into the tapered hub and into the flared portion of said hub.

3. A tack button comprising a shell, said shell having an upwardly extending peripheral rim and a depressed hub tapering toward its lower extremity, the said hub being provided with a ring-like portion at its lower extremity, the bottom of the hub being slightly concave and perforate, an anvil in said shell having a concave portion and said portion terminating short of the ring-like portion of the hub, a cover over said shell and the anvil adapted to mutilate the prong of a tack and guide and deform the same into the said ring portion of the hub.

4. A tack button comprising in part a shell having a flat portion, an upwardly extending rim, a tapering hub, a Hared portion at the lower extremity or' the hub slightly less in diameter than the upper diameter of the hub.

5. A tack button comprising a shell, a rim, a tapering hub, an enlarged ring-like portion at the bottom ot the hub, the hub being closed with the exception of a slight perforation, an anvil in said shell, a cover over said shell and the Ianvil adapted to mutilate and jam the prong of a tack within the ring-like portion on the hub and to substantially amalgamate with and clinch the metal forced away from the hub perforation as the said tack enters the hub.

6. A button comprising a shell having a hub tapering toward its lower extremity, a ring-like portion at the lower extremity of the hub to form a contacting area greater than the minimum diameter of the tapered hub, an anvil in said shell and terminating above the ringlike portion, a cover over said shell, a tack fastener jammed within the bottom of the hub and deformed against said anvil to thereby iill up the space in the ring portion of the hub.

7. A tack button comprising a shell, said shell having a flat portion, an upwardly extending peripheral rim, an integral hub merging with the flat portion and the said hub tapering toward its lower extremity, the Said hub provided with a iared portion at its lower end, the bottom of the hub being Slightly concave and provided with a perforation at the upper extremity of the concavity.

In testimony whereof We aiiix our signatures.
