BUTTON.

SPECIFICATION forming part of Letters Patent No. 247,155, dated September 20, 1881.

Application filed July 29, 1881. (Model) To all whom it may concern:

Be it known that we, JASON E. BRAMAN and'HENRY W. LITTLE, of Providence, in the State of Bhode Island, have invented an Improvement in Buttons, of which the following is a specification.

Our invention relates to that class of buttons where the shoe is pivoted to the end of the post and turned back upon its pivot for insertion into the button-hole or removal therefrom; and it consists in the improved construction and arrangement of the several parts, as hereinafter fully set forth.

Figure 1 is an elevation, showing an edge view of the post. Fig. 2 represents the button as shown in Fig. 1, with the shoe cutaway, so as to show the interior parts in section. Fig. 3 represents a plan view of the interior mechanism of the shoe. Figs. 4: to 10, inclusive, repiesent the details of the button.

In the accompanying drawings, A is the head of the button, B the post, and O the external cap of the shoe.

The post B, formed of flat stock, is made in L form, the two arms I) I) being made about equal length, as shown in Figs.2 and 9. The pivots a a, for the joint of the shoe are formed at-the end of the arm b of the post, and the studs a a, formed at the sides of the arm I), serve, in conjunction with the catches d (1 of the curved push-bar D, to hold the shoe firmly in its locking position, as shown in Fig. 1.

The shoe-cap O is made in cup-form, as shown in plan and section in Fig. 4, the raised flange 0 being cut away at c to provide an opening for the operation of the push-bar D, and also at F to provide for the post when turning the shoe upon its joint.

The spring E is constructed as shown in plan and section in Fig. 5, and is placed at the bottom of the shoe-cap, as shown in Fig. 2.

The flanged piece F (shown in plan and section in Fig. 6) is struck up from sheet metal, and provided at its central portion with a crosspiece, g, serving to form an abutment for supporting the back of the spring G. (Shown in plan and back view in Fig. 7.) The raised flange of the piece F is cut away at e to receive the outer end of the push-bar D, a plan and section of which are shown in Fig. 8.

The push-bar D is placed within the rim of the piece F, so that the catches d d cover a portion of the space formed by the notches jj in the flat back portion of the piece F.

The spring G is placed between the pushbar D and the abutment g, and serves to hold the push-bar against theinner side of the flange of the piece F.

The back plate, H, of the shoe is cut out and bent, as shown in plan and section in Fig. 10, the spurs h h serving, in conjunction with the turned ends 1' i of the piece F, to form a suitable recess to receive the pivots b b of the post B. The edge of the flange c of the shoe-cap O is turned over the edge of the plate H, and holds the several parts firmly in place. When the shoe 0 is in the position shown in Fig. 1 the shoe is locked to the post by means of the catches d d and the studs a a; and in order to remove the button from the button-hole it is necessary to force back the push-bar D, thus releasing the studs a a, from the catches d d, when the shoe maybe turned back on its joint, as shown by the dotted lines in Fig. 2. The spring E, by its pressure against the side of 7 the arm I) of the post B, serves to hold the shoe firmly in its extended position for removal or insertion.

We claim as our invention- 1. In a button, the combination of the pivoted shoe 0 and the L-formed post B, provided with the studs a a, the push-bar D, provided with the catches d d, and the spring G, whereby the pivoted shoe 0 is held in its looking position, substantially as described.

2. In a button,the combination of the spring E, intermediate piece, .F, push-bar D, spring G, plate H, and shoe-cap O, jointed to the L- fortned post B, provided with the studs 01. a, substantially as described. 0

3. In a button, the combination ofthe spring E, intermediate piece, F, plate H, and the L- formed post B with the shoe 0, having its raised flange 0 cut away at f, whereby the shoe may be turned in line with the arm I) of the L-formed post B, substantially as described.

4. In a button, the combination of the shoecap 0, the intermediate piece, F,provided with the turned on flanged ends 2' t, and plate H, provided with spurs h h, whereby suitable re- Ioc cesses are formed to receive the pivots b b of the post B, substantially as described.
