BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 264,520, dated September 19, 1882.

Application ined July 20,18872. (No model.)

To allwtom 'it may concern Be 1t known that I, CHARLES ERLANGEE,

' a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented a new and useful Improvement in Button.

Fasteners, of which the following is a specification. Y

Myimprovement relates to buttonfasteners; and the Objectis to provide cheap and efficient means to fasten buttons 'to fabrics, whereby the employment of thread is dispensed with and the fastening is effected by means of metallic connections of peculiar form and construction.

I am aware that metal staples have been used before for this purpose, andI lay no claim, broadly, thereto.

In the button-fastening devices in general use the staples, after having been inserted through the button, have their points turned, the turning over beingdone after such staples have been passed through the button, leaving but a single thickness of the staple ends or arms as bearings or retaining-binders for the button or disk, as the case may be. Such staples therefore provide in practice but a single strand at their ends to resist strain, which easily loses the grip.

My improvement consists in fortifyin g and strengthening the terminal ends ofthe staplearms before they are inserted in the button, such strengthened ends bei n gafterward turned down on a plane parallel with and against the middle or dish of the button.

Referring to the drawings that accompany this specification, Figure 1 represents the blank of a disk having at each opposite side an extending arm or strip, which, in practice, are doubled over at their ends before being passed through the button, and are then turned dat against the surface of the button. Fig. 2 represents a shoe or washer having a notch at each side edge, into lwhich takes one of the extending arms of the disk shown in Fig. l. Fig. 3 is a side view ot' Fig. 1. Fig. 3x is a side view of Fig. 1, showing the ends of the arms turned down before being inserted in the button. Fig. 4 is an enlarged face view of abutton attached to a piece of fabric bythe devices shown in\Figs. 1, 2, 3. Fig. 5is a section on the line x of Fig. 4:. Fig. 6 is a face View of a button attached to the upper side of a piece of fabric, the disk being inserted from the front. Fig. 7 is a section on line y of Fig. 6. Fig. 8 is a sectional view of a button fastened to a piece of fabric, said button swaged up or dished up centrally.

Similar letters of reference indicate `like parts on each figure.

A isla metallic disk, having on each ofits opposite sides an extending arm or strip, c. Fig. l shows this disk dat in its blank form before its arms are turned over. I n the side view thereof shown in Fig. 3 the dotted lines indicate the position of the arms a when the ends a are bent over and returned inwardly after the button is completely fastened.

B is a shoe or Washer having notches or recesses b at its opposite side edges, into which takes respectively one ofthe arms a of the disk A, thus lopking the parts together and preventing lateral movement.

C is the button proper, having ordinary cable-holes c.

y D is a piece ofthe fabric ot' a garment.

c represen'ts the end portions of the arms a. (plainly shown in Figs. 5, 7, S) as bent over and turned under, (also in dotted lines, Fig. 3,) thus presenting resistance in direct opposition to the power applied and strain when the button is in use, the peculiar function of the doubled ends being to afford an unyielding grip on the button-surface that will not bend when t-he button is subjected to strain, as it would do it' the ends a were only one thickness of metal. Before the arms a are turned over on the button, as described, I place under them, against the surface of the button, a side-notched shoe, B, and into each respective side notch one of the arms engages as it is turned up and bent over, thus interlocking them together.

In Figs. 4, 5, the disk A is represented as applied to the rear of the fabric, and the notched shoe B as applied to the front ot' the button; 95

ton the supplementary shoe B may well be dis- IOC) pensed with, as the swnged or dished part of scribed, before beng'passed through the'hu't- 'm the button presents arecess, which materially ton, and adapted, after beingr passed through adds to the resist-ance of thedoubled ends a the cable-holes of a. button, to be turned over ofthe arms a. on the surface thereof, substantially as de- Having 110W fully described my invention, scribed.
