BUTTON Filed Dec. 28, 1931 Jrvuewfot Fm/v/ru/v/Z WHITE Patented Nov. 21, 1933 UNITED STATES BUTTON Franklin R. White, Waterbury, Conn., assignor to The Patent Button Company, Waterbury, Conn., a corporation of Connecticut Application December 28,1931 Serial Nor 583,566

'1 Claim. (o1. 24-95) My invention relates to new and useful improvements in buttons, and more particularly to that type of button which is attached by a tack fastener, the prong of which, when once driven into the button, will be deformed to tightly secure the button in position.

One of the objects of the present invention is to produce a button comprising a shell of rela- I tively soft metal and a die or vice formed of relatively hard metal, which is positioned in the shell, so that the latter will receive and deform the prong of the fastener, thus avoiding any possibility of the fastener being driven up into R I and mutilating the cap of the button.

Still another object of the invention is to so form the shell and the die that the die will be preliminarily held in position in the shell while the button is being assembled.

As is well known, buttons are attached by button attaching machines and when the die or anchor is securely held in the proper position within the button, there is no possibility of the prong being driven up in the hub of the button h and not properly received within the die.

' Still another object of the invention is to provide a button comprising but two pieces and a cap, that is, a shell and a die, and the two parts so formed that the die will be preliminarily properly held in position, after which the cap is crimped on the button shell in the usual manner. The button is then ready to be thrown in the button attaching machine and attached to the garment, or to whatever material it is to be secured to.

' With these and other objects in view, the invention consists in certain new and novel arran'gements andcombination of parts, as will be hereinafter more fully described and pointed out in the claim.

40 Referring now to the drawing,

lines showing the ribbon from which it is formed; Fig. 2 is a bottom plan view thereof;

Fig. 3 is a top plan and a cross section of the shell for receiving the die;

Fig. 4 shows the die preliminarily held in position;

Fig. 5 is a sectional view of the completed button and showing it attached to the cloth; Fig. 6 is a slight modification of the die.

Referring now to the several views, and for the moment to Fig. 1, there is shown the die 1, which is formed of a relatively hard metal, such as steel, and is cut from hard steel ribbon stock 2 The die is formed in a press (not shown) and,

Fig. 1 is a side elevation of the die, the dotted as may be seen, is formed with the head 3 and the hub 4. The die is also formed with a small internal chamber 5 in the head, while thehub is hollow, as at 6. When the littledie is pressed into shape, there will be seen the two small openings 7, and it will also be seen that the hub is, in reality, formed by the two ends of the cut stock, so that these parts of the hub may be sprung slightly, as will be hereinafter mentioned. In other words, the hub is split longitudinally. 651

Now in Fig. 3, there is shown the shell of the button 8 which has the integral hub 9, the outwardly extending bottom wall 10, and the upwardly extending flared wall 11. The walls of the hub 9 are turned upwardly for a slight distance to form a flange 12 about which the hub of the die is to be crimped, as will also be shortly mentioned. The bottom wall of the hub, of course, is open for the reception of a prong fastener. 5,

Also, by turning the lower edge of the hub upwardly, as may be seen in the several views, this lower surface of the hub, which will contact with the goods, will present a smooth and rounded surface so as to prevent any tearing or cutting of the cloth during the attaching process. Referring for the moment to Fig. 4, which shows the assembly, the button'shell 8 may be seen with the die 1 seated therein, and it will be noticed that the head of the die rests on the 3m upper inner peripheral wall 13 of the hub about where it merges with the bottom wall 10 of the shell.

The height of the head of the die 3 is such that it will extend in the same plane as the upper peripheral edge of the flared wall 11. The length of the hub of the die is also such that it will extend downwardly and substantially flush with the bottom wall of the hub of the shell. 1

When the die 1 is forced within the shell and seated, a short plunger (not shown) will be forced up into the hub 4 of the die. This plunger will be greater in diameter than the opening of the hub of the die, so that the ends 14 of the split hub 4 of the die will be expanded and tightly crimped within the flange 12 in the hub of the button shell 1.

Thus, it will be seen that the die is anchored within the button shell. After this, a cap 15 will be crimped about the wall 11 of the button shell to complete the assembly of the button.

In Fig. 5, I have shown the cloth 16 with the tack fastener 1'7 driven therethrough and up through the hub 4 of the die and into the hollow chamber 5 within the die, wherein the tack 110 that if the button has a cap that is ornamented centrally, this arcuate upper wall of the die" may rest up under and support the cap. and still not disfigure the cap.

From the foregoing, it will be seen that I have provided a shell whose hub is so formed that a die, as also shown, may beplaced within the hub, after which the split hub of the die-' will be slightly spread, so as to clench or inter-- lock with the hub to thus hold the die in place, and then. thetack may be driven up into the die. to tightly hold the button in its fastened position.

I. am aware that it is old to form similarly shaped dies, butIamnot aware of a die of this nature that is to be used with a one-piece button shell, and wherein the die may be clenched in position about a flange in the hub of the button shell.

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

A button comprising a one-piece shell having an integral hollow hub, the lower end of the hub turned inwardly and upwardly to form n. flaring mouth in the hub, a die formed of one-piece of hard steel ribbon stock and said die having a relatively narrow chamber in its head, and an integral reduced elongated hub, said huh. beingsubstantially split throughout its length, the side walls of the head of the die extending slightly downwardly in cross section and then inwardly and then slightly upwardly to merge with the top of the hub of said die, the hub of the die being slightly expanded near its lower endand. overlying the flared walls of the. mouth. of the hub to clinch the flared walls of the mouth of the hub of thebutton shell to tightly hold the die in position.
