BUTTON.

QEECIFICATION forming part of Letters Patent No. 350,776, dated October 12, 1886.

Application filed Yovember 23, 1885.

To all whom, it may concern Be it known that I, MADISON D. SrnrMAN, a citizen of the United States, residing at De Kalb, in the county of De Kalb and State of Illinois, have invented certain new and useful Improvements in Buttons, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure I is a central vertical section of the head of my improved button attached to the fabric. Fig. 2 is a similar view of the flanged tube thereof, detached. Fig. 3 is a similar view of a modified form of cap, showing also its flanged tube detached. Fig. 4 is asimilar view of the cap provided with my unlocking device. Fig. 5 is a plan view of the unlocking-lever. Fig. 6 is a side view of the same. Fig. 7 is a sectional view of the stud. Fig. 8 is a plan view of the washer used for securing the stud to the fabric. Fig. 9 is a vertical section of a solid stud.

This invention relates to separable buttons; and it consists in the peculiar combinations and the novel construction and arrangement of parts, all as more fully hereinafter described and claimed.

In the drawings, A designates the cap, preferably of the form shown. B is the stud-receiving tube, provided with a base, I), corrugated, as shown, so as to form a ridge, 1), for a purpose soon to be explained. G is an eye let of ordinary construction. These parts, to gether with the spring D, (hereinafter described.) constitute the head of the button, which is attached to the fabric in the following manner: The cap A and tube B are first united by turning the edge (I of the cap A under the edge of the base b of the tube, leaving a recess, a, between the base of the tube and the inturned edge of the cap, as seen in Fig. 1. These parts are then placed upon the fabric and the eyelet put through from the other side, and when the parts are pressed together the end of the eyelet, striking against the ridge 2/01" the corrugated base of the tube, is deflected or turned outward under the base of the tube into the recess a", above referred to, formed between the base of the tube and the edge of the cap, thus firmly uniting the parts and securing the head to the fabric. The tube B within the cap is formed with a hori Serial No. 183,769. (X0 model.)

the end of the cap, as in Figs. .1. and 2; but

said end is just turned under the edge of the flange of the base,which, it will be noticed, is rounded sufficiently to hold the two parts together, as clearly shown in Fig. 3.

The stud E, which maybe either solid or hollow, as preferred, is formed with a round head, 0, a flange, e, and a notch or groove, 0'. This stud is put through the fabric. and when made hollow is secured thereto in the following manner: (i is a washer, having a central opening, 9, which is a'little smaller than the 'stud B. At the center this washer is slit at two or more places, as shown in Fig. 8. This washer is slipped on over the stud, as shown in Fig. 7, the slit portions yielding sufficiently to allow of the passage of the stud. Vhen the outer edge of the washer comes in contact with the fabric, pressure on the slit portions will cause them to contract and assume their normal position, forcing or pressing in the metal of the tube, and the edges of the slit portions entering the depression made in the tube prevent the separation of the parts.

Vhen a solid stud is used, it is provided with an annular groove or depression, 74, to receive the edge of the slit port-ions of the washer, which is the same as that used with the hollow stud, and is applied in the same way, it being of course understood that the slit portions of the washer spring into the groove in the stud when they are coincident therewith. I preferably, though not necessarily, press or bend up the slit portions of the washer, as shown in Fig. 7, so as to slightly increase the size of the central opening, so that it can more readily and easily be slipped over the stud. This is desirable when used with a hollow stud, but not when a solid stud is used.

XVhen it is desired to connect the two parts of the button, the stud is inserted in the tube B of the head, the round head of the stud read- 11y passing by and pressing outward the spring w1thin the slot in the tube until the groove in thestud is coincident with said slot, when the spring falls into the groove in the stud and secures the two parts of the button together. The two parts may be separated by a sudden pull on either the head or the stud, or by pull- 1ng both in opposite directions; but I prefer to use, more especially when I employ a stud having a straight-sided recess, as shown in Fig. 9, what I term an unlocking device, whlch consists, preferably, of a piece of sheet metal, I, formed in the shapeshown in Fig. 5,

and provided with a hand-piece, t, and twoarms or bifurcations, iz". Each of the arms of this lever is provided with a spur or proection, j, inclined, as shown in Fig. 6. In Fig. 4 this, device is shown in position. Its hand-piece i projects through a slot, A, in the cap A, while its arms 2" t" straddle or extend one on each side of the tube B, so as to leave a free passage for the stud. -Thc spurs j engage the end of the spring D that is in the slot in the tube. When the stud and head are connected with the spring engaging the groove in the stud, and it is desired to disengage or separate the same, it is only necessary to press in upon the lever I, when the spurs j, engagmg the spring D, force the same out of the slot inthe tube B, and consequently out of engagement with the groove in the stud, when the latter is free to be removed. i

While I have shown and described what at the present time I consider the preferable form of unlocking device, I do not wish to confine myself to that particular construction, as it is evident that the same may be varied to some extent without departing from the spirit of my invention.

When it is desirable, as it sometimes will be,

as shown in dotted lines in Fig. 4. 1

\Vhat I claim as new is of the cap A, the perforated tube B, and the spiral spring having its upper end coiled aroundand closely embracing said tube and its end entering the perforation therein, with astud having a notch or groove adapted to receive the end of said spring, substantially as described, I j V 2.

inclosed in said cap, with its apex extending toward the top of said cap, and having a base adapted to deflect the fastener when the two are forced together, substantially as described.

3. The combination, in a separable button, of cap, A, a perforated tube inclosed in said cap and having corrugated base I), provided with the inturned flange, and a fastener, as 0, adapted to expand into the recess in the base, substantially as described.

4. The combination, in a separable button, of a fastener, as O, a tube, B, having a base the inner part of which is inclined upward and adapted to deflect the fastener when the two are forced together, and a cap constructed to inclose the tube and the deflected end of the fastener, substantially as described.

7. The combination, with a separable button having a notched stud and a spring catching into the same, of a bifurcated plate having spurs or projections adapted to disengage the spring from the stud, substantially as and for the purpose specified.

8. The combination, in a separable button,
