SHUBAEL COTTLE, OF NEW YORK, N. Y.

BUTTON.

SPECIFICATION forming part of Letters Patent No. 391,230, dated October 16, 1888.

Application tiled November 21, 1887. Serial No. 255,708.

To all whom t may concern:

Be it known that I, SHUBAEL COTTLE, of the city, county,and State of New York, have invented a new and useful Improvement in Stud, Collar, and Sleeve Buttons, of which the following is a specification.

My invention relates to a stud, collar, or sleeve button of novel construction, the distinctive features of which are a hollow head and hollow post and a solid back, the whole being produced from sheet metal,so that no opening is left into the interior of the button.

The object of my invention is to simplify the construction of the button, to render the same stronger and more durable, to give the button a uniformly smooth exterior, and to do away with any openings in which dirt may collect.

In the accompanying drawings, Figure l is a vertical section of my new button on the line a: x of Fig. 2, and Fig. 2 is a plan view.

Similar letters of reference indicate like parts.

A is the head of the button, made of sheet metal and hollow.

B is the shank or post, also hollow and made of sheet metal.

C is the base or back, which is solid metal, and which therefore forms substantially a flange around the closed lower end of the hollow post.

In the embodiment of my invention here illustrated I show the hollow head, hollowV shank, and solid back formed of asingle piece of metal, and this construction I consider preferable.

I produce my aforesaid button preferably in the following manner: I tirst make a tube of thin metal, having at one end a solid body of metal, which closes said end, the other end of the tube being open. I then compress the middle portion of this tube in suitable dies to (No model.)

produce the shank or post B, and then Hatten or draw out the solid portion to produce the solid base or back C. The head A then is open at the top. This opening I close by adjusting the button in a lathe, and by mea-ns of a suitable spinning-tool spinning in the circumferential edge of the opening until the aperture is entirely closed by the metal meeting, when the upper surface of the head A is finally smoothed off, thus completing the construction ofthe button.

In another application for Letters Patent filed December 9, 1887, Serial No. 257,385. I have fully described and claimed my aforesaid process, which is therefore herein disclaimed.

I claiml. A stud, collar, or sleeve button consisting of a single piece of thin metal without an opening into its interior, and having a solid back and a hollow post and head, substantially as described.

2. A stud, collar, or sleeve button having a hollow post and head, consisting integrally of a continuous closed metallic shell and a back formed of a flange of solid metal surrounding the lower part of said post, substantially as described. y

3. A stud, collar, or sleeve button having a hollow post and head, consisting integrally of a continuous closed metallic shell and a back integrally formed of a single thickness of said shell, substantially as described.

4. A stud, collar, or sleeve button of thin met-al, having a hollow head, a hollow post closed at its lower end,and a flange at the lower part of said post integral therewith and of a single thickness of said thin metal, substantially as described. SHUBAEL CO'ITLE.
