BUTTON.

SPECIFICATION forming part of Letters Patent No. 619,277, dated February I4, 1899.

Application filed February 26, 1897. Renewed January 6, 1899. Serial No. 701,410. (No model.)

T0 on whom it may concern.-

Be it known that I, GEORGE J. OAPEWELL, of Hartford, Connecticut, have invented a new and useful Improvement in Buttons, which improvement is fully set forth in the following specification.

This invention relates to the manufacture of two-part metallic buttons composed of the button proper and a fastening device whereby the button is attached to the cloth. Buttons of this general character are used in great quantities on trousers and other garments. These buttons are made of sheet metal, and one common method of making them is as follows: The face disk is stamped from sheet metal and turned up at the edges, the eyelet is drawn out, flanged at one end, and attached at the other to the back disk. The two disks are then fastened together by turning the edge of the face disk over that of the rear disk. The attaching device is in the form of a tack. Its shankis passed through the cloth and eyelet and bent or upset against the face disk in such manner as to prevent its withdrawal.

The object of the present invention is to avoid the waste of material attending the above method, to reduce the number of operations, and to produce a stronger button and one which can be more firmly attached to the cloth than those now in use.

The invention and its utilities can be better explained in connection with the aceompanying drawings, in which Figure 1 is a sectional view illustrating a common form of sheet-metal button. Fig. 2 shows in section the several parts of such button detached. Fig. 3 illustrates a blank from which the improved button is made. Fig. 4 shows the partly-completed button; Fig. 5, a punch by which final shape is imparted to the button. Fig. 6 shows the completed button; Fig. 7, the fastening-tack therefor, and Fig. 8 the button attached to a garment.

The button shown in Fig. 1 is made by stamping disks or b from sheet metal and shaping them, as shown, to form the face and rear, respectively, of the button. The hollow shank c is also stamped and drawn to the form shown and brazed or otherwise secured to disk 17. The latter is then attached to disk (1 by turning over the edges of the latter. To attach the button, a tack e is inserted through the cloth and the hollow shank and driven against disk at, causing its end to bend in the hollow part of the button, so that it cannot be withdrawn through the shank. The head of the tack and the flange o of the shank compress the cloth between them. These buttons are likely to become loose. The disk on and flange 0 lack sufficient strength to admit of the tack being driven home with the degree of force requisite to make a permanently firm attachment. When the tack becomes loose, the cloth in contact with the button becomes quickly frayed and worn.

In making the improved button a blank (shown in Fig. 3) is cut of proper length from wire, so that there is no wastage of stock. It is upset at one end, forminga head f and shank g, and the latter is by drilling or otherwise hollowed out, as shown in Fig. 4. A flange IL is now formed at the end opposite the head, and for this operation a punch, such as shown in Fig. 5, may conveniently be used. This punch has a slender teat or projection 'i, which enters the hollow shank, and as the metal is upset it not only forms the flange h, but also flows inward around the teat, forming a contracted neck to the hollow shank, as shown in Fig. 6. These simple and easilyperformed operations result in a solid button in one piece, having an interior chamber 70, with a contracted opening through the base. The button is secured to the garment, as already described, by a tack e, as shown in Fig. 8. Owing to the great strength and resistance of the head of the button and of flange h the tack can be driven home with any desired degree of force, and the chamber k may be of definite size, such that the metal of the shank of the tack which is to be upset therein may fill the cavity and make a permanently tight connection, such as will resist all ordinary incidents of usage and laundering.

Preferably the punch is so shaped as to form a slight concavity inthe base or flange h, and the head of tack e is slightly convex on its under side, so as to force the cloth into the concavity and insure a tight hold.

Having thus described my invention, what ICO a single piece of wire and consisting of a head,

a hollow shank, and a flanged base, the cavity in the shank being of larger diameter than the opening at the base, with a tack having a shank of soft metal, of such size that, When driven into the shank its end will be upset and substantially fill the cavity therein, as set forth.

In testimony whereof I have signed this specification in the presence of two subscrib- 20 r ing Witnesses.

GEORGE J. GAPEWELL.
