Letters .Patent No. 88,099, dated March 23,1869; antedatecl M11/rch 5, 1869.

The Schedule referred to in these Letters Patent and making pmx-t of the lame.

To all whom it ma/y concern.-

Be'it known that I, WILLIAM W. WADE, of Medford, in the county of Middlesex, and State of Massachusetts, have invented certain Improvements in Buttons, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure lis a perspective view, representing a flat circular plate cut from a sheet of metal.

Figure 2 is a view representing the said circular plate with its-outer edge turned up, and two slits, or openings 'cut near its centre.

Figure 3 is a section through a button with a back of my improved construction.

Figure 4, detail, to be referred to.

My invention consists in making the back and eye of a button from one and the same piece of metal, that is to say, a back of metal with its eye, or shank, struck up, or otherwise formed therefrom, in contradistinction to a back and eye made of separate pieces of metal secured together.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

A flat sheet of metal is passed under a series of punches, which cut it into circular plates, A, Iig. 1.

These plates are then carried, in succession, upon a revolving table, and deposited in a horizontal position within the top of a female dieof the required form.

f A circular forming-punch, with a male cutting-die enclosed, now simultaneously descends, the punch striking up the periphery, or outer edge of the circular plate, and holding it rmly in place, while the cntting-die makes therein twoA slits, a, of the form shown in iig. 4, and then turns them up, as seen in Iig. 2.

The forming-punch and male cuttingdie now withdraw together, carrying with them the metal back until it is free from the female die, when the cutting-die recedes, to allow a pair of nippers to advance, and press or turn up the two inner edges, b, of the slits, or openings a, in the back, A, thus uniting the two edges up from a metal back, is more rigid, and not liable to v break, and the thread cannot pull out, as frequently happens with the cloth back and eye.

The cloth back and eye are also objectionable, for the reason that a'hole has first to be. made through it by anawl, or needle, for the passage .of the thread, whereas, by my improved construction, the opening for the thread is already made, and the thread may be y readily entered without the employment ofthe awll or needle.

Again, my improvement possesses au advantage over the ordinary metal-back button, where the back is in one piece, and the eye is in a separate piece, (of wire, usually,) and connected thereto, as in such a back both ends of the thread must pass through the same hole in the work, in order to bring the back as near to and as parallel therewith as its construction will admit. It cannot, however, be brought close to the surface ofthe work to which it is attached, owing to the distance of the eye from the back, whereas a back of my improved construction may he drawn down snugly in contact with the work, thus giving a neater and more `finished appearance, and therefore more desirable for upholsterers purposes.

C'lwlm.

What I claim as my invention, and desire to secure by Letters Patent, as an improvement in buttons, is-

A back, A, and eye, or shank, c, made in one and the -same piece of metal, by 'cutting and swaging up into proper form, substantially as described.

WILLIAM W. WADE.
