IMPROVEMENT IN BUTTONS.

Specification forming part of Letters Patent No. 174,1 6l, dated February 29, 1876; application filed January 17, 1876.

To all whom it may concern Be it known that I, JOSEPH R. SMITH, of Waterbury, in the' county of New Haven and State of Connecticut, have invented a new Improvement in Buttons; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a lull, clear, and exact descripton of the saine, and which said drawings constitute part of this specilication, and represent, in

`Figure 1, perspective view of the rear of the button Fig. 2, central section.

This invention relates toan. improvement in fabric-covered buttons, and such as are constructed with a fabricated protuberance .on

strength of the closing to retain the fabric.`

rlhe center of this rear fabric protrudes through a perforation in the back, to afford means for securing the button; hence all the strain brought upon the button comes upon this labric, and it frequently happens that it is drawn out .so as to loosen or free the button.

The object of this invention is to' prevent the possibility of the drawing out or displacement of the fabric; and it consists of a series of inward perfor-ations, forming a roughenedinner holding-surface in the back of the button, to form a burr on this disk, to enter the fabric between the disk and the lining, so as to se! center is placed between the rear disk and the filling c, then all closed together at the rear edge, so as to securely bind the parts. Usually the disk b has been left plain, depending upon the friction between the disk b and the lling to hold the fabric e.

ln this improvement numerous perforations, f, are made into the disk b after the button is closed, or in the process of closing, so as to form burrs upon .the inside, entering or engaging with the fabric. 'lhese burrs so lirmly hold the fabric as to preyent the possibility of its displacement; hence the button is greatly strengthened and its durabilityA increased.

l claim- An improvement in the manufacture of covered buttons, consisting of the perforations in the rear disk, whereby the inner. or holding surface of the disk is roughened', substantially as and for the purpose set forth.
