HENRY SIMON, OF PROVIDENGE, RHODE ISLAND.

SHIPtT-STUD AND SLEEVE-BUTTON-- Specificat-ion forming part of Letters Patent No. 37,777, dated February 24, 1863.l

.T0 all whom it may concern:

The object of my invcntion is to produce arp ticles of this character more economically than heretofore, both in respect to the quantity of precious metal employed and in the amount of manual labor required, while at the same time the appearance of the article and its strength and durability are not impaired, and which also has the advantage of not crocking or soiling the nen when woru. It has heretofore been the practice to construct these articles either from thick metal or from disks of thin sheet metal soldered at the edge, and the space within filled with solder or some base metal, in order to obtain the degree of strength which the article requires. If stock therefore of a high grade is used the expense is correspondingly increased, while, on the other hand, ifa poor quality of gold is used the article is inferior as one of ornament and of little durability. Again, if thin disks of metal are used, and the space between them filled with solder, the increased cost of manufacture nearly compensates for the amount of gold saved.

I make my improved stud or sleeve-but-ton as follows: I strike up a single disk for the faces of the stud or button of thin sheet metal, using only one disk if the stud is of the variety shown in Fig. 2, and two disks only if it be a double-faceci stud, as shown in Fig. 8. Although I do not limit myself to the use of gold for these disks, yet this metal should be employed, as the amount of stock required for the purpose is exceedingly small, the plate not requiriug to be any thicker than a sheet of the thinnest paper. These faces should be struck with a turned or' cup-formed edge, for

the purpose of receiving the hacking which I employ.

Having obtained the shell by any of the modes of manufacture employed, I first coat the inside with solder and then fiow upon itfilling the back fiush with the edge of the shell-a surface of enamel. This enamel is composed of any of the cheap compounds of which this material is made, the most usual being silex, borax, and an oxide of one of the metals. The composition is placed upon the back of the shell with a brush, and then is subjected to a heat sufficient to produce liquefaetion. After the enamel has become cooled the stud or button shows on onc side the face of the metal only, and upon the other side the surface of enamel only.

I have described only the process of making the faces of the stud, but it must be understood that the bar of metal which holds the two faces together, or the coil which acts iu place of the second face, Fig. 1, is attached to the disk by solder before enameling by solder in the usual way.

Besidcs the obvious advantages which I gain both in economy of labor and of material used over any of the methods now employed, it is clear that this description of stud or but-- ton will not soil the linen, from the fact that its inner face is of a material which leaves no crock like that which comes from gold. In point of strength and (lurability, too, it is fully equal to the strongest article of the kind now made.

I do not limit myself to any form of stud or button, my improvement being applicable to any7 of the forms iu use.

What I do claim as my invention, and desire to secure by Letters Patent, is-

The improved stud 01' button described, composed of a shell of sheet metal with abacking of enamel, the `whole article being substantially such as specified.

In witness whereof I have hereunto set my hand this 24th day of December, A. D. 1862.

HENRY SIMON.
