BUTTON.

SPECIFICATION forming part of- Letters Patent No. 540,350, dated June 4,1895. Application filed February 1, 1895. Serial No, 536,901. (No model.)

To all whom, it may concern;

Be it known that I, CHARLES A. BRYANT, a citizen of the United States, residing at Wakefield, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Buttons, of whichthe following is a full specification, reference being had to the accompanying drawings, wherein like letters represent like parts.

My invention relates to that class of buttons which, instead of being sewed to the material of the garment or other article on which they are used, are mechanically riveted thereto by means of a single-pointed, malleable tack; and consists in certain novel features of construction hereinafter described in detail.

Referring to the accompanying drawings, Figure 1 shows in section the struck-up blank from which the shell of my button is formed. Fig. 2 shows the same with the edge of the flange turned under. Fig. 3 shows in section the anvil-piece of my button. Figs. 4 and 5 show modified forms of same. Fig. 6 shows my completed button, and Fig. 7 the samein modified form. Fig. 8 shows the two parts of my button placed in the dies by which they are closed together.

In my button a blank A is first struck up preferably into the shape shown in Fig. 1, having the flange h and shank a. The edge d of the flange Z) is then preferably turned under as shown in Fig. 2, away from the shank a. I then form the anvil piece B, Fig. 3. This is preferably a cylindrical chamber or eyelet which has a contracted entrance f and whose upper end is preferably rounded, as shown, and which may have a slight flange e projecting beyond the body of the cylinder. This anvil piece 13 serves to turn the point of a tack which is thrust up through the holef and to confine the upset portion of the tack in order to prevent its being drawn out again. This anvil piece is secured to the under side of the shell A, as shown in Fig. 6, by means of closing dies X Y.

As shown in Fig. 8, the anvil piece B is placed in the concavity W of the lower die Y resting on its under perforated end h. The

shell A is placed concentrically above the anvil, its shank a projecting upward, and

supported by its outer edge d, which rests on the outer edge R of the die Y. The upper die is then brought down upon the shell A with the effect that the shank is first forced down over the anvil B, the edge d remaining at the same height as before. The edge 0 of the shank then strikes the inwardly sloping surface Z of the die, which forces it inward and under the flange e. of the anvil B, firmly 6o clinching the same. At the same time, the flange b is preferably turned backward, pressed between the dies, and shaped as shown in Fig. 6 so that it presents the appearance of an ordinary cup-shaped button having a protuberance in its center. The lower end of the anvil B projects slightly below the shell, forming a shank or neck for the button, its.

flat under side 77. resting on the material to which it is secured by a tack E, which passes 7c up through the material, enters the hole f, and is upsetinside the anvil B. This method of securing the shell and anvil piece together by causing the metal of the shell, by one operation, to flow down and about the anvil piece is a very rapid, economical, and efficient one, and produces a very desirable button at a minimum cost. It will be seen that the way in which my button is made is unlike the method usually employed, andinsteadof perforating the shell for purposes of attachment, the anvil piece is swaged on to the under side of the shell without perforating the same.

In the modified forms of anvil piece shown in Figs. 4 and 5, that shown in Fig. 4 is approximately a spheroid having its under side 71 flattened and perforated atf to receive the tack. When this is closed into the shell, it is completely inclosed by the shank at whose edge a clinches under the under edge 71. of the anvil B. In this case, it is necessary to provide some support in the die Y, so that the edge 0 of the shell can pass under the lower edge h of the anvil. The other form of anvil, as shown in Fig. 5, consists of an eyelet H, having the preferably rounded and flanged heade, the shank 2', and rolled in neck 9. It will be seen that this neck 9 is preferably rolled in very near the end of the shank, and serves to form a contracted opening through which too the tack may pass, and by which it is prevented from being drawn out after it has been headed up in the eyelet above. As in the first case this anvil is clinched to the shell of the button by means of' its flanged head e, which is gripped by the edge 0 of the shell, and its shank 7; projects down to form a neck for the button. Fig. 7 shows a button constructed with this modified form of anvil piece, and to this, I have added a further modification in the flanged eyelet D, which encircles the lower end of the shank 'i, and is gripped thereto by being rolled into the neck, or by being held thereto by frictional contact. This flange D acts as a seat and rests on top of the material in order to hold the button upright, and grip the material between itself and the head of the tack beneath.

It is obvious that the shell A of'my button can be covered in any way desired.

Iclain1 In a button the imperforate shell A, and the anvil piece B, provided with a cavity having a contracted entrance, situated on the lower side of the imperforate shell A, and firmly swaged thereto, in combination with the tack E, all substantially as described.

In witness-whereof I have hereunto set my hand.

CHARLES A. BRYANT.
