BUTTON.

SPECIFICATION forming part of Letters Patent No. 579,989, dated April 6, 1897.

Application led ctober 21,1896. Serial No. 609,593. (No model.)

To all whom. it 727,601/ concerner Be it known that I, PETER KERR, a citizen of the United States, residing atA Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Buttons; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in buttons, and more particularly to that class of such articles used for cuff-buttons and the like, my object being to provide a construction of button which can be readily inserted into a cuff or similar article without marring the buttonhole or without the difficulty usually attendant upon inserting buttons in buttonholes of articles of stiffened fabric.

To this end, and also to generally improve this character of butt-on, my invention relates to the various matters hereinafter described and claimed.

In the accompanying drawings, which illustrate my invention, Figure I is a perspective of the present invention, and Fig. 2 is a sectional elevation thereof.

Referring now more particularly to the drawings, a represents the top member of a button, l) the shank, and c the back-plate. In the present instance the back-plate has radially projecting therefrom a point c', which is somewhat hooked. This permits the button to be easily inserted into even a very stift cuff by simply placing the point c in the but-tonhole and turning the button, the hooked point tending to force the back-plate in place. It will be noticed that the edge of the back-plate extends from the base of the point around the shank to the outer end of the point, thus forming a species of spiral. This of course facilitat-es the entrance of the plate into the but- W'hen, however, a button thus contonhole.

structed has been inserted in a cuff, it is somewhat diflcult to withdraw the same from the buttonhole. In order to obviate this difculty, I have a thread b upon the shank, said thread being a continuation of the point upon the back-plate. Thus the-buttonhole is continually held upon this thread, and to withdraw the button it is only necessary to turn the same backwardly, when it will be readily unscrewed from the buttonhole. It will be noticed that the threaded shank tapers toward its top. The object of this is to make the shank tend to screw the cuit up against the bottom of the top member a, thus holding the button securely in the buttonhole.

The construction is simple and eective in its operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A button comprising a top member, a shank upon said member, said shank tapering outwardly'from its top toward its base, and a thread upon said shank, substantially as described.

2. A button comprising a top member, a shank, a back-plate, said back-plate having a point extending therefrom the edge of the plate being continuous from the outside of the point around the back member to the inside thereof, the shank tapering outwardly from the top of the top member and a thread upon said shank, said thread being as a continuation of the point upon the back member, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

PETER KEER.
