BUTTON.

SPECIFICATION forming part of Letters Patent N0. 624,996, dated May 16, 1899.

Application led February 23, 1898. Serial No. 671,284. (No model.)

' the two sections of the button being secured together and to the garment by turning the point of the tack after the parts are united.

The object of my invention is to provide a simple, durable, and efficient closed-top tackbutton, and one which can be made with a few 'parts and at little expense.

To these ends my invention consists in the novel arrangement and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure l represents aside elevation, partly in section,

I Y chamber at any point across the same.

of one forrn of button embodying my invention, the button being shown in this figure as secured in place upon the garment or carrier thereof. Fig. 2 is a detail bottom view of the button-head. Fig. 3 is a detail plan view of the tack-section.,

The button head A of my invention is formed from a single disk of sheet metal and is in the form of a closed-top double-walled button-head in which is provided what I term a central tack-point-receiving chamber, as indicated at The lower Wall of the buttonhead is indicated at f, while g represents the upper wallor top of button-head. The button-head is provided with a hollow tack-receiving shank c, which is closed upon all sides and is formed integral therewith and which is of less extent in diameter at its narrowest portion than the diameter of the tack-pointreceiving chamber so as to prevent the parts from being separated when the point of the tack is turned in the chamber. By the diameter of the tack-point-receiving chamberI mean the size of the tack-point-receiving It will likewise be observed that when the point of the tack is turned within the head it coutacts with the upper and lower walls fg of the head and prevents a movement of the parts with relation to each other. From the shank a extends an outwardly projecting bearing-flange b, which is formed integral with the hollow shank and the button-head.

B constitutes the tack-section or back of the button, and this section comprises the hack proper, c,f rom which projects the pointed tack proper, d. This tack d is provided with abearing-shoulder e, against which the inner wall of the hollow shank a of the button-head is adapted to bear when the parts are connected as represented in Fig. l.

C represents the cloth of the garment, through which the tack d is projected to secure the parts together and the button in position upon the garment.

The manner of uniting the sections of the button will, it. is thought, be obvious. The tack is projected through the cloth C of the garment to which the button is 4to be secured, and a tack d thereof is projected through the tack-receiving opening in the hollow shank a.

Pressure is exerted upon the head A, which results in the point of the tack being bent over in the tack-point-receiv'ing chamber at substantially right angles to the passage in the shank to prevent the head and tack-sec tion from .being disconnected, and thus secure the button to the garment, as represented inFig. l. The shoulder e on the tack limits the downward movement of the button-head with relation to the tack and provides a space between the bearing-flange b and the back of the tack-section. By these means the button is rigidly maintained in place on the fabric, the fabric being clamped between the bearing-flange b and the buttonback or tack-section B. All movements of the button in the direction of its shank are prevented by these means. 4What I mean by closed-top button is one wherein the tackreceiving opening does not extend entirely through the button-head.

It will be observed that by my invention I am enabled to provide a closed-top tack-button which is made of two pieces, the smallest possible number of pieces with which a tackbutton can be made. It willlikewise be seen that by making the back in a single piece and the head, shank, and liange in a single piece I dispense with all joints in the individual parts, thereby not only increasing the strength of the button, but at the same time greatly reducing the cost of manufacture. Thus, for instance, the head and back of the button can be produced ata single operation or handling, parts are dispensed with, and the time and expense of setting up and assembling the separate pieces which go to make up the individual sections of the button are saved. It will also be observed that by providing a closed top for the buttonhead l may thereby produce a highly-ornamented button or one wherein suitable inscriptions or advertisements may be produced upon the button-head.

- While I have shown and described the tack-section as being provided with a bearing-shoulder, it is obvious that such shoulder may be dispensed with.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1sa

l. A separable two-piece button comprising a closed-top double-walled head struck up from a single disk of sheet metal and having a tack-poin t-receiving chamber in the center thereof, ahollow tack-receiving shank closed upon all sides and made integral with said head and having its narrowest portion of less extent in diameter than the diameter of the central tack-point-receivin g chamber, a tacksection provided with a pointed tack which is adapted to bear against the upper wall or top g of the button-head when the parts are united and to be turned thereby within the tack-point-receiving chamber .in the head at substantially right angles to the passage in the hollow shank to unite the button-head and'tack-section and to contact with the upper and lower walls of said head to prevent a movement of the parts with relation to each other and thus secure the button to the garment, and a bearing-flange formedintegral with said shank and adapted to bear upon the material to which the button is Secured.

2. A separable button comprising a closedtop double-walled head struck up from a single disk of sheet metal and having a tackpoint-receiving chamber in the center thereof, a hollow tack-receiving shank formed integral with said head and having its narrowest portion of less extent in diameter than the central tack-point-receiving chamber, an outwardly-projecting bearing-flange formed integral with said shank and a tack-section, the pointed tack of which is adapted to bear against the upper Wall or top g of the buttonhead and to be turned thereby within the tack-point-receiving chamber in the head at substantially right angles tothe passage in the hollow shank to unite the button-head and tack-section and to contact with the upper and lower walls of said head to prevent a movement of the parts with relation to each other and thus secure the button to the garment, said tack-section being provided with a bearing-shoulder against which the hollow shank is adapted to bear when the tack is within the shank and the parts united, whereby a space is provided between the back of the tack and the bearing-flange of the buttonhead and a rigid connection between the parts is formed.
