ATnNT JACOB J. LINDAUER, OF NEW YORK, N. Y.

vBUTTON OR STUD.

SPECIFICATION forming part of Letters Patel-1t No. 323,167, dated July 28, 1885.

Application filed May 6. 1885. (No model.)

To ally/kont t may concern:

Be it known that I, JACOB J. LTNDAUER, of New York, in the county and State of New York, have invented a new and useful Inl` provement in Detachable Buttons or Studs, of

which the following is a specification.

I will describe a button or stud embodying my improvement, and then point out the various features in a claim.

In the accompanying drawings, Figure 1 is a centraltransverse section of a button or stud embodying my improvement. Fig. 2 isa back view of the same. Fig. 3 is a central transverse section of a button or stud of modiiied 1 5 form embodying the said improvement.

Similar letters of reference designate corresponding parts in all the gures.

Referring first to Figs. l and 2, A designates the headofa button or stud. This head may be 2O made wholly of metal or of a metal rim and a center of stone or analogous material.

To the back of the head A two bars, B, are secured in such manner that they may be swung into a position side by side, as illustrated in dotted outline, or aposition in line, as-

illustrated in full lines in Fig. l. Thus they are enabled to be easily inserted in button-holes, and after their insertion to be extended across the same, so that the button or stud will be 3o securely attached to the articles containing the button holes. The bars B are J-shaped.

Their bent portions b extend through spaces or slots between the back of the head and bridge pieces a affixed to the back of the stud. At one end of the bent portioi s b of the bars B are short approximately straight portions b', and at the other end of the bent portions b are long straight portions bg. The long straight portions b2 of the bars, by coming in contact when the bars are swung in one drection,limit the swinging of the bars in one direction,and the short straight portions b, by coming in contact with the back of the head A, limit the swinging of the bars in the other direction. The bent or curved portions b of the bars are provid ed with intermeshin g teeth, and theteeth of one engage with a rack-bar, C, which slides in a bearing, c, provided' on the back ofthe head A. By moving the slider-bar G out or in the bars B may be swunginto the positions described. The sliderhar O has a projectiomd, at one end,whereby it can be conveniently manipulated. The slider-bar C may be kept so tight in its bearings that it will not be liable to accidental displacement, or it may have a catch combined withit to preclude such mishap.

The button or stud shown in Fig. 3 is like the one previously described,except that instead of the J-shaped bars B, l use bars B having sec tor-sh apedends bprovided with intermeshing teeth,and mounted on-pivotpins b", connected to the head A. The teeth ofone ofthese sectorshaped bars B engage with teeth on a slider'- bar C.

WVhat l claim as myinvention, and desire to secure by Letters Patent, is

In a button or stud, the combinatiomwith a head, of swinging bars having intermeshing teeth,and a slider-bar provided with teeth engaging with the teeth of. one of the swinging bars, substantially as specified.
