BUTTON AND BUTTON-FASTENING.

SPECIFICATION formingpart of Letters Patent No. 254,842, dated March 14, 1882. Application filed October 30, 1880. (No. model.) Patented in Germany April 28, 1881.

To all whom it may concern Beitknownthat I, EMIL PFLUG, of thecity of Berlin, inthe Kingdom of Prussia, German Empire, have invented Improvements in Buttons and Button-Fastenings, of which the following is a specification.

The accompanying, drawings form a part of and illustrate the invention.

Figure 1 is an axial section of a button and its fastening prior to the final locking; Fig. 2, the same section after looking; Fig. 3, a view of Fig. 1 from below; Fig. 4, a View of Fig. 2 from below; Fig. 5, a cross-section of the the washer; Fig. 6, a side view of a button fastened to a piece of cloth; Fig. 7, an axial section of a globular button for shoes, 850.

Similar letters of reference indicate corresponding parts.

The body of the button is composed of an upper part, a, and a lower one, b, of any suit able material and convenient size and design. The two parts are united by crimping the upper part, a, over the edge of the lower, 1), which may be done by pressing them in dies or by spinning. Thepartbextendsdownward,forming a'nipple or teat, c, to keep the wider portion of thebutton at the right distance from the cloth to which it is fastened. A narrow strip, 61, of soft metal-as brass,iron, &c.is pointed on both ends and doubled inside of the button, its ends projecting from a hole in the lowest part of the nipple c. This strip d is secured firmly to the button when the parts a and b are united, as above described. The washer c has an oblong hole in the center, large enough to allow the protruding ends of the strip d to pass when lying close side by side, and two rcccsses in its circumference of the same width as the strip (1. The washer c has a depression, 6, extending from the central hole to the recesses on the edge, into which the strips (1 are bent when the fastening is done. After having pierced the cloth g by means of the pointed ends of the strip 01, the washer e is put on the latter and then pressed firmly down against the cloth. The ends of the strip (1 are now bentapartand pressed down into the depressed parts of' the washer e, taking care that the points are forced into the cloth, Fig. 2. The button is in this way rigidly fastened or locked to the cloth, and cannot be separated from it, except by tearing the cloth or by purposely openingthe look by bending back and straightening the twoends of the strip 01. In this case the button may be taken oft'and fastened again anywhere else.

Fig. 7 shows another shape of the parts a and b of the button, and, according to that, another form of the concealed portion of the strip (1. Such globular buttons are used on boots or shoes.

It must be remarked that these buttons may be used on any wearing-apparel-drawers, overcoats, Waistcoats, shoes, gloves, &c.-and made of any desired size and shape and of any suitable material.

What I claim is- 1. The hollow button-head described, formed of two pieces, a and b, the latter extended into the nipple c, as shown, in combination with the fastening-strip d, bent upon itself and incased in the head a b, which it fills, substantialiy as set forth.

2. The button described, consisting'of the two head-pieces a and b, fastened together as described, the fastening-piece d, having a bent portion lying within and filling the head a b, and the washer e, havinga central hole, radial depressions e, and recessed edges for e11 gaging the points of the fastening-piece cl, all constructed and arranged as herein set forth.

This specification signed by methis 8th day of October, 1880.

EMIL PFLUG.
