BUTTON.

SPECIFICATION forming part of Letters Patent No. 392,568, dated November 6, 1888.

Application filed January 24, 1888. Serial No. 261,729. (No model.)

.To CLZZ whom. it may concern:

Be it known that we, Josnrrr A. PHILLIrs and GUMBY S. BLUM, J r., citizens of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvem-entsin Buttons; and we do hereby declare the following to bc a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improve ments in buttons, and it has reference more particularly to that class of buttons commonly known as suspender or pantaloon buttons, in which two metallic disks or shells provided with a suitable cross-bar or thread-support form the essential parts of the button.

The object of our invention is to provide a button of this description the crossbar of which is so constructed as to withstand a very considerable amount of strain or pressure without injury to the button, and in which the different parts of the button are firmly and rigidly. united.

A further object of our invention is to provide for such buttons a cross-bar made from a separate piece of sheet metal, constructed so as to lie as near as possible to the opening in the backplate of the button and combined therewith in such a manner as to prevent the bar from revolving and avoid injury to the thread holding the button to the garment; also to so construct the various portions of the button as to simplify the process of manufacture and assembling, thereby producing a button that possesses the qualities of simplicity, strength, durability, and economy.

To this end our invention comprises a front disk or shell having a central opening therein in the usual manner, a back shell having a projecting hub, and an intermediate disk or cross-bar of peculiar form, and rigidly secured in place between the front and back of the button.

Our invention comprises certain other novel features, some of which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a top or face view of our improved button; Fig. 2, a cross-section of same on line m 00 of Fig. 1; Fig. 3, a sectional elevation of the back shell; Fig. 4, a top or plan view showiug theintermediatc disk within the back shell; Figs. 5, 6, 7, and 8, side elevations of the intermediate disk before the bending operation; Figs. 9 and 10, plan views of a modified form of cross-bar; Figs. 11 and 12, plan views of the disks shown, respectively, in Figs. 8 and 7, showing the lips forming the tubular crossbar in the finished disks.

Referring to the drawings, A represents the front disk, with the edge of its central opening turned downward toward the interior of the button and preferably outward, as shown, for the purpose of properly deflecting and guiding the needle in its passage through the button.

13 shows the rear disk or shell of the button, which is held in place by the overlapping edge of the front disk, A, in the usual manner. This disk is formed with a hub, 7), whose inner edge, I), is preferably turned upward and outward within the interior of the hub, so as to form an eyelet-shaped opening that is free from sharp edges and presents a smooth passage for the thread, in a manner more particularly set forth in Patent No. 377 ,446, granted to us February 7, 1888.

0, Figs. 11 and 12, represents the central or intermediate disk, having lips or ears 0 0 cut on either side of its central portion. disk 0 is cut from suitable sheet metal -such as brass or sheet-tin and the lips c c, after being out, are folded under the central portion of the disk to form the rounded tubular crossbar a. The lips shown in Fig. 12,when folded, form the straight bar represented in Figs. 6 and 7, while the curved lips in Fig. 11 are converted into a curved or depressed bar, as illustrated in Fig. 8. The outer edges of the disk 0 are turned upward to form the peripheral flange cZand are preferably so shaped as to conform to the interior contour of the back shell, B.

It will be seen by referring to Fig. 2 that the rounded portion of the bar 0 is of such length as to just fit within the walls of the huh I), and that its ends rest upon the depressed eyeletshaped flange b of said hub. This construction not only brings the bar very close to the rear end of the button, but enables it to with- The stand a very considerable amount of strain without danger of bending or breaking. It will also be noticed that the flange c of the disk 0 extends slightly above the rim of the back B when placed within the latter. (See Figs. 2 and 4.) By this construction the disk and its bar are firmly pressed against the back 13 and its flange b, respectively, during the operation of closing the button, and are thereby rigidly held in position between the front and back disks and prevented from rotating.

It will be apparent that the disk 0 has but to be placed within the back B when assembling the buttons to find its own bearing, and that owing to the flexibility of the center disk and the slightly-yielding nature of the flange b the pressure exerted upon the cross bar when in use will only serve to render this bear ing more perfect and secure.

While we have described and prefer to make the bar-piece in the form of a disk, we do not desire to limit ourselves to this form, as the bar may be made in the form shown in Figs. 9 and 10. This style of bar, moreover, has certain advantages, as it can be manufaetur ed from a continuous strip of sheet metal with comparatively little or no waste, permits of rapid manipulation, and can be made of any desired degree of curvature. The construction is fully and clearlyillustrated in the drawings, the flanged end pieces,0, being clamped between the front and back disks, as shown in Fig. 2. In all the figures the bar is of sufficient length to extend clear across the opening in the front and rear disks, and as every portion of the button with which the retaining-thread can come in contact is smoothly finished abrasion of the thread cannot take place. How ever-,we do not wish to be understood aslimiting ourselves to the particular forms herein shown, as our improvements are equally applicable to buttons of different construction.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A button comprising a front and back disk or shell and an intermediate disk of sheet metal conforming substantially in shape to and nesting within the back disk or shell, and provided with arounded central portion forming the thread-bar of the button, and with an upwardly extending peripheral flange arranged and adapted to bear against the front disk or shell, substantially as and for the purpose described.

2. In a button, the combination, with the front disk, of the back disk having a projecting hub and interior flange and an intermediate disk of sheet metal having a depending rounded central portion or thread bar arranged to fit entirely within the said hub and to be partially supported by said flange, the edge or periphery of said intermediate disk being turned upwardly against the front disk of the button, substantially as and for the purpose described.

In testimony whereof we afflx our signatures in presence of two witnesses.
