PAUL NEIDIIARDT, OF CHICAGO, ILLINOIS.

"BUTTON,

SIEE(`JI1 "ICA'IIO1\1l forming part of Letters `Paterna No. 527,502, dated October 16, 1894.

Application led February 9,1893. Serial No. 461,653. (No model.)

Be it known that I, PAUL NEIDHARDT, of

Chicago, in the State of Illinois, have invented certain new and useful Improvements in Buttons; and I do 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 known as collar and cud buttons, the object "being to construct a button in two parts y after more fully described and pointed out in the claim.

In the accompanying drawings, Figure lis a perspective view of the completed button.

Fig. 2 is a sectional view showing the button attached to the collar band of a shirt, and

Fig. 3 is a detached perspective View.

A represents the completed button, which is constructed in two parts as shown in Fig.

3. The upper part of said button is provided with the ordinary head B, from which projects the shank C. This shank is preferably made conical or beIlshaped, the free or enlarged end of which is` slightly flattened as at o, for the purpose to be hereinafter eX- v plained. The shank C is conically bored as shown at d, said bore having its greatest diameter at the bearing surface a, while its smallest diameter is at `a point where the screw threaded hole e begins, which latter extends the desired distance up in the shank i C toward the head B.

The lower part of the button A, is composed of a base or bottom F and a screw threaded post G, which latter is integral with the bottom F. The outer surface or circumference of the bottom F is bent over on itself as at b and forms a bearing surface for the shirt band when the button is in the position shown in Fig. 2. The portion of the button 'shank C a few turns to the right.

`F at the base of the screw is also conical in form as shown at c,which latter tends to force the shirt band or that part surrounding` following mannerz-The button is first separated as shown in Fig. 3. The screw threaded post G of the lower portion of the button is passed through the button hole of the shirt band from the rear and is held therein until the front portion of the button is screwed on the post G, which is accomplished by placing the conically bored or bell-shaped end of shank C over the post G and pressing the former backward until the latter comes in contact with the screw threaded hole e, after which the parts are locked together by giving the By thus securing the button to the shirt, it will be seen that the entire shank is for thesole use of accommodating the ends of the collar.

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

As anarticle of manufacture, a button made in two separable parts constructed the one to screw into the other and receive the object to which the button is attached between them, one part having a head or en largement and a funnel shaped shank, screw threaded internally, the smaller end of the .shank being next to the head or enlargement,

and the other part consisting of an externally screw threaded post and an enlargement, the base of the post being conical or funnel shaped to enter the open end of the shank, and the inner face of the enlargement having a recessed seat corresponding inshape and size to the free edge of the shank,`substantially as and for the purpose described. i

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