BUTTON.

SPECIFIGATIONforming part of Letters Patent N 0. 631,379, dated August 22, 1899.

Application filed February 28; 1899. Serial No. 707,145. (No d l.)

To all whom it may concern:

Be it known that I, LEWIS A. PLAT'l, a citizen ot' the United States, and a resident of Waterbury, in the county of New Haven and State of Connecticut, have made and invented certain new and useful Improvements in Buttons, of which the following is a specification.

My invention relates to an improvement in buttons, and more particularly to that kind or class thereof which are generally known and referred to as bar buttonsthat is, a button constructed in part of a bar, over and around which the fastening-thread is passed to secure or attach the button in place-the object of my invention being to provide an article of this kind which can be easily, readily, and cheaply made and assembled by automatic tools or machinery and with but little or no hand labor.

With these and other ends in view my in vention consists of certain novel features of construction and combinations of parts,as will be hereinafter fullydescribed ,and pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional view of my improved button resting within a die and containing a wire staple. Fig. 2 shows the method of fastening the sta- Fig. 3 is a plan view of the completed button; and Fig. 4, a sectional view thereof, taken on theline 4.4. ofFig. 3.

Referring to the drawings, Arepre'sents a button formed with the top or flange a, the edge C of which is curled or turned under in order to impart a finish thereto. The central part of the button is depressed to form the hub or shank c, the lower edge d of said hub or shank being turned or flanged inwardly to form a supporting-ring for the staple B. Instead, however, of depressing the center of the button to form the hub or shank said hub may be made of a separate piece of metal, as is commonly done in this-class or style of buttons, and which therefore needs no further illustration or description, such construction being familiar and wellknown to those skilled in the art. This staple is made of wire of any suitable thickness and of a size to nicely fit within the hub of the button, the corners of the staple resting upon the ring or inturned flange (Z, as illustrated in Figs. 1 and 2. In

assembling the partsthat is, the button proper and the staple the staple by means of proper tools not necessary to be shown herein is cut and formed from a piece of wire and fed'into the button A, as illustrated in Fig. 1, said button being supported in the die E, made to nicely contain said button and provided with grooves or recesses e at the top thereof. The plunger D is made to descend, the lower end thereof, which is shaped as shown, entering the button and forcing the endsf of the two arms of the staple outwardly into the metal of the hub of the button, as illustrated in Fig. 2, the metal of said hub being forced.

outwardly into the grooves e of the die, thereby effecting a secure and permanent locking of the staple within the button. Upon withdrawal of the plunger D the button is removed from the die in its completed condition.

From the above it will be seen that my improved button is very simple in construction, that the staple is permanently and securely locked'in place, and that it materially differs from the many other buttons which have heretofore been constructed in part with staples, in that the security of the button does not depend upon the looking or fastening of the ends of the staple, but upon the supporting ring or flange d of the hub of the button. In other words, the strain imposed upon the staple does not fall upon the two ends f thereof, but upon the rounded corners h thereof, which bear upon the inturned flange d, the locking of the ends of the staple in my improved button being effected for the purpose of preventing the staple from being accidentally disengaged from the hub of the button.

Having fully described myiuvention, what I claim as new, and desire to secure by Letters Patent, is

1. A button consisting of a button proper and provided with a depressed center or hub, the lower edge of said hub being turned or flanged inwardly to form a supporting-ring, and'a staple having two upright arms and fitting within said depressed center, the rounded or bent corners of said staple resting upon said supportingring, and the free ends thereof locked or fastened in said hub, substantially as described.

2. A button consisting of a button proper formed with a depressed hub or center, the

lower edge of which is bent imvardly forin- Signed at Waterbury, in the county of New ing a seat or supporting-ring, and astaple Haven and State of Connecticut, this 20th day 10 having two upright arms and fitting Within of February, A. D. 1899.
