DETACHABLE BUTTON.

SPECIFICATION forming part of Letters Patent N o. 666,855, dated J anlfary 29, 1901. Application filed July 16, 1900. `erial liloL 23,760. (N0 model.)

To @ZZ wtont it TV1/ty concern:

Beit known that I, WILLIAM U. RAINE, a citi/.en of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, haveinvented new and usefullmprovements in Detachable Buttons, of which the following is a specification.

My invention relates to improvements in detachable buttons.

The object of my invention is to provide more reliable holding devices than those heretofore used and to adapt such devices for use on cloth-covered buttons, regard being also had for neatness of appearance and simplicity of construction.

In the following description reference is had to the accompanying drawings, forming part of this specification, in which- Figure l is a central sectional view of my improved button, drawn ou a line crossing the springretaining channel. Fig. isasimilar view taken at right angles to that of Fig. l. Fig. 3 is a View of the shank and baseplate. Fig. l is a top view with the cap removed.

Like parts are identified by the same reference-letters throughout the several views.

The head of the button is composed of the cap A and -a holding-plate B, the latter being provided with a channel C and stem-tube D. The cap A is adapted to fit over the holdingplate B, as shown in Figs. l and 2, and where the cap is covered with cloth E the edges of the latter are inserted between the parts A and B, and thereby securely held in place. The edge of the capA is turned in at a after the holding-plate B is adjusted in position, thus preventing the removal of the latter.

A flat spring is doubled upon itself to form the spring-arms F and arranged on edge in the channel C, as best shownin Figs. l and 4. This spring is preferably formed with a central bulge in its respective arms to facilitate the entrance of the shank. The edges b of the holding-plate B are preferably turned downwardly, Fig. 4, to cover the ends of the spring and hold the latter in the channel.

Referring to Fig. 3, it will be observed that the base G is formed with a shank H, having its sides tapered at g near its upper end and its end provided with a head I, having barbs J. The sides of the head I are also tapered,

as shown in Fig. 2, thus giving it a wedge shape, which facilitates its insertion between the arms F of the spring.

When it is desired to unite the parts of the button, the shank H is inserted through the stem or shank tube D, with the barbs in a plane parallel with the sides of the spring-arms F. Owing to the wedge-shaped contour of the shank-head I the spring-arms-are easily separated lo permit the passage of the shank, which is given a quarter-turn as soon as the barbs J have cleared the spring-arms. The latter are then permitted to spring inwardly against the tapered sides g of the shank, when a slight backward movement of the latter causes the barbs to engage over the sides of the spring-arms, as shown in Fig. l.

When it is desired to release the button, the base and shank are pressed inwardly and turned a quarter-turn, thus separating the springs and bringing the barbs into a position for withdrawal. The base is preferably provided with a notch M, indicating the position for withdrawal.

I am aware that it is not new to provide buttons with holding-springs and headed Shanks; but I believe I am the lirst to provide a shank with a barbed head in combination with holding-springs adapted to be engaged thereby.

What I claim as new, and desire to secure by Letters Patent, is-

1. A detachable button, comprising a holding-plate, provided with a channel therein and a central tubular aperture; a cap covering said holding-plate and channel; springarms located in said channel; and a base provided with a shank having backwardly-projecting barbs, adapted to enter said tubular aperture and permit the engagement of said barbs with said spring.

2. A detachable button comprising a holding-plate; a cap covering the same; a cloth covering for the cap-plate, having its edges engaged between the holding-plate and the cover-plate; a base provided with a shank adapted to enter the holding-plate, and having backwardly-projecting barbs; and flat spring-arms supported on edge by the holding-plate, and adapted to be engaged by the barbs of said shank.

3. A detachable button, comprising a hold- IOO ing-plate; aeap therefor; inberposed springholding-plate; and a base provided with a arms; and a base provided with a shank havshank havingl backwardly-projeoting barbs ing baokwardly-p'rojecting barbs adapted to adapted lto enter lbhe channel between the engage the arms, said shank beingt-apered spring-arms, and to engage the same. 5 below the barbs, and said spring-arms being In testimony whereof I aix my signature x5 arranged to press elastically against the tain bhe presence of two witnesses. pered sides of the shank.
