COMPOSITION-FACED BUTTON.

SPECIFICATION forming part of Letters Patent No. 395,186, dated December 25, 1888.

Application filed October 15, 1888. Serial No. 288,154. (No specimens.)

T aZZ whom, it may concern.-

Be it known that I, ISAAC SMITH, of Brooklyn, in the county of Kings and State of New York, have invented a new Improvement in Composition-Faced Buttons; and I do hereby declare the following, when taken in connection with accompanying drawing-sand the letters of reference marked thereon, to be aful, clear, and exact description of the same, and

which said drawings constitute part of this specification, and represent, in

Figure 1, an edge view half in section; Fig. 2, a section representing the introduction of the back into the front; Fig. 3, an edge View I 5 half in section of the metal blank for the front,

detached. 5

This invention relates to an improvement in the manufacture of buttons in which the body is metal, but the exposed surface covered with a composition or non-metallic material applied to the blank in a plastic condition, and is an improvement upon the invention for which Letters Patent of the United States No. 381,at38 were granted to me April In my previous patent the blank for the face of the button was of cup shape, made from sheet metal, and substantially the same as that employed for cloth faced buttons, ex-

3 cept that the blank was perforated with numerous holes, and so that a plastic composition applied to the face of the blank would be forced through the holes in the blank and become interlocked therewith, so that a very 3 5 thin coating of composition could be employed, and yet insure its secure attachment to the metal blank. The flange or the side of the cap was left uncoated and closed over the back in the usual manner for closing the faceblank over the back in cloth buttons. This under the ordinary construction of. buttons leaves the side of the cup or front exposed uncoated,because the coatiu could only extend to the point where the bend was to be made in the side of the cup in closing it upon the back.

The object of my present invention is to so construct the front and back that the blank for the front may be wholly covered-that is to say, so that the bending of the flange or side of the cup may be avoided, thereby enabling the blank for the front to be covered on its face entirely over its sides.

To this end my invention consists in constructing the blank for the front with its flange or side turned inward-that is, contracted-and with a concentric rib upon the inside of the cup adjacent to the inclined flange, and a cup-shaped blank for the back, its external diameter corresponding to the contracted diameter of the flange of the front, and so that as the back is forced into the front its edge will strike the said rib and be deflected outward between the said rib and the inclined flange of the front, whereby the back and front will be firmly interlocked and as more fully hereinafter described.

In Fig. 3 the blank for the front is shown in half transverse section detached and without the covering. It is made from sheet metal struck into cup shape, and the side or flange (4 turned back from the front and inward, so that the internal diameter of the flange at its edge is less than the internal diameter of the blank in the plane of the front. In the front and adjacent to the side of the blank an illternal rib, b, is formed substantially around the blank and concentric to the flange a, as clearly seen in Fig. 3. This rib leaves a space,

(I, between it and the surrounding flange a, the adjacent surfaces of the flange and of the rib being inclined inward, as shown. The rib l) is best formed by making a circular depression in the face of the button. The blank for the front is perforated, as in my previous patent, and the blank is covered with the plastic material 6, as seen in Fig. 2, the ma terial extending over the edge and so as to cover the flange or side of the front, as shown. The application of the plastic material to the 0 back is best made substantially in the same manner as described in my previous patent, and not necessary to be described in this application further than to say that suitable dies are provided by which the requisite p ressure is applied to the plastic material to bring it to the required shape, and at the same time to cause it to enter the perforations in the front, wherebyit will securely interlock therewith. The back f is made from sheet metal, of cup shape. The external diameter of the side or flange 9 corresponds to the internal. diameter of the outer edge of the flange a of the front, and so that the back may be set into the front, the flange inward, as seen in Fig. 2. The flange g of the back strikes the outwardlyinclined surface of the rib b in the front, and, suitable force being applied, the flange of the back is deflected over the rib 1) into the space between the said rib and the flange a on the front, as seen in Fig. 1, and so that the back is firmly interlocked with the front. The depth of the back should be such as to permit it to be entirelyinclosed within the front, as represented in Fig. 1, or substantially so. Under this construction I am enabled to cover the entire surface of the front, because in the closing of the back and front together there is no bending effect produced upon the front or any part of it; hence no disturbance of the coating.

I do not claim, broadly, a button having an under-cut groove in its front portion, with a ring-shaped disk inserted into this under-cut recess, and so as to hold the eye portion in place, as such I am aware is not new.

It will be understood that I claim nothing in this application shown or described in my before-mentioned patent; but

WVhat I do claim, and desire to secure by Letters Patent, is

The herein-described improvement in composition-faced buttons, which consists in a metal cup-shaped blank for the front, constructed with its side orflange turned inward, so that the inner surface is inwardly inclined from the plane of the front, and the front also constructed with a concentric rib upon its inside adjacent to its flange and correspondingly inclined, the outer surface of the blank covered with a composition, the said composition extending over onto the inclined outer surface of the flange and so as to cover that surface, combined with a cup-shaped back, the external diameter of the flange or side corresponding to the internal diameter of the flange of the front at its outer edge and forced into the front against the inclined surface of the said rib, and thereby deflected outward between the said rib and the side of the front, whereby the said back is interlocked with the front, substantially as described.
