Parent BUTTON AND BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 232,587, dated September 21, 1880.

Application filed June 11, 1880. (No model.) Patented in France April 16, 1878, in Bogium April 16, 1878, and in Great Britain April 16, 1878.

To all whom it may concern:

Be it known that I, EDMUND WRIGHT, a subject of Great Britain,residing at Birmingham, in the county of Warwick, England, have in vented certain new and useful Improvements in Buttons and Button-Fasteners, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a partof this specification.

My invention relates to double-plate fasteners for buttons, studs, solitaires, and the like having shanks terminating in suitably-formed heads to engage with the fastener, as hereinafter described.

In order that theinvention may bemorereadily understood, I will describe it with reference to the accompanying drawings, in which- Figure 1 represents the form of shank adapted forpapier-mach, composite, or metal buttons. Figs. 2 and 3 represent vertical sections of a papier-mach and of a metal button, respectively.

In buttons the heads of which are made in two parts, or having an upper and lower shell, the bottom part, a, is pierced and recessed for the reception of the shank, as shown in Figs. 2 and 3, and in certain classes of buttons the upper part, a, may also be recessed for the reception of the shank-head,

In making papier-mach or composite buttons, Fig. 2, the upper and lower parts are glued together, as shown, and pressed to shape in dies in the ordinary manner after the introduction of the shank b, which is inserted from the top side of the lower part, a. By this means the rivet-shaped head of the shank is firmly embedded in the button, and the shank is held very securely.

Fig. 3 represents another form of button, generally made of metal, and suitable for trousers, 850. Here the shank b is inserted in the lower shell in the same manner, the upper shell hearing on the shank-head and retaining it in po sition, as shown. Linen, Florentine, and pearlbuttons may also be constructed in a similar manner. In any case the lower-end of the shank terminates in a rivet-shaped head, 0,

which engages with a double-plate fastener constructed as hereinafter described.

Figs. 5 and 6 show, respectively, a front and back view, and Fig. at a cross-section, of one form of doubleplate fastener.

Referring to Figs. 5, 6, and 4,fis the front plate, consisting of a small steel or metal disk with a radial slot, 9, extending to the center of the disk, the slot being enlarged atits outer end for the passage of the head 0, the remainderof the slot being only the width of the narrowest part of the shank, as shown.

The diskfis covered on the under side by a second plate, h, of thin metal, having two cavities or indentations, 'i t", for the reception of the small head 0 on the shank when the latter is inserted in the slot g, one of such cavities being opposite the one end and the other opposite the other end of the slot g. These cavities are separated by a sort of bridge at the joint over which the head 0 must pass in order to enter the cavity '5, and by which it is retained therein.

The sectional views show the manner of binding or connecting the disk and coveringplate together, which is effected by turning the edges of the cover over those of the disk in an ordinary press.

The button and fastening are shown connected in Figs. 7 and 9, the action of the fasteningbcing as follows The shank-head 0, having been passed through a hole in the material or article, is inserted at the outer end of the slot 9 and slid along to the other end of the slot, thereby slightly springing the plate It while passing the bridge or highest point j, after which the head 0 falls into the cavity '6, and the two plates close again, thus preventing the withdrawal of the head 0, except by reversing the operation j ust described, the but ton being finally secured in the fastener by pressing the outer bulb, t, into the opening g, as shown in Fig. 9, by means of suitablyformed pliers, as shown in Fig. 8, which-rep resents a pair of pliers constructed in the ordinary manner, with the addition of a spherical projection, v, on one jaw and a correspond ing cavity, 11, on the other.

The great advantage of these fasteners, be-

sides their security, is their slight thickness and the absence of sharp projections on the under side, which would hurt the foot when the fastener is applied inside a boot. These fasteners may be covered with linen or other woven fabric in the ordinary manner of covering linen and other buttons.

Having described the nature of the said invention and the manner of performing the same, I declare that what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination of the button a a, shank I), slotted disk f, and covering-plate h, provided with bulbs or cavities i t" and bridge j, as and 15 for the purpose specified.
