METHOD OFY FORMING BUTTON-HOLES.

SPECIFICATION forming part of Letters Patent No. 236,155, dated January 4, 188.1.

Application filed August 13l 1879.

useful Im proveinents in Re-enforcement of Button-Holes; and l do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to'make and use the same, reference being had to the accompanyin g drawings, and to letters of reference marked thereon, which form a part of this specitioation. Y

My invention relates to a new method offorming button-holes in iiexible fabrics; and it consists, essentially, in interposing between two thicknesses of material, one thickness of which has a key-hole-shaped aperture in it, the button-hole lining or re-enforcement, formed of crimped leather andV constructed with a bead surrounding the button-slit, the bead serving as a guide whereby to properly locate the crimped .lining,'hide the cut edges of the key-holeshaped opening, and also to protect said cut edges from wear, as will be hereinafter fully explained.

In the drawings I have illustrated my invention as being applied to the button-ily of a shoe, in which drawings- Figure l is a plan view of a portion of a shoe-upper, showing the button-holes. Fig. 2 is an enlarged view of the same, taken on line :c y, Fig. l; and Fig. 3 is a view, detached, of one of the button-hole linings or re-enforcements.

A is the upper, formed of any desired material, such as leather or some of the woven fabrics usually employed for that purpose.

a a, a a are a series of key-hole-shaped openings, formed in the part Ain proper position relative to the scalloped edge of the buttontly.

B is the button-Hy lining, of cloth or leather.

C C (l C are the crimped-leather button-hole linings or re-enforcements, such as may be conveniently made upon the machine patented by me June 18, 1878. These linings or re-enforcements are each constructed with a bead, c, extending in a continuous line around the button-slit c, as is plainly shown in Fig. 3;

.0 Vstitching may be dispensed with without de-y and in applying them I interpose thembetween the upper and the lining with the bead projecting through or into the key-hole-shaped openings a. After the upper, the lining, and

lthe button-hole linings or re-enforcements have been secured to each other, I then cutor vpunch a slit, b, in the button-dy lining by means of a suitable instrument, which is inserted through the button-slit of the buttonhole lining or re-enforcement, this slit c serving as a guide to determine the position of the slit in the button lining or re-enforceinent, as will be readily understood.

It will be readily seen that the bead on the button-hole lining serves as a guide to facilitate locating the re-enforcenient in proper position relative to the key-hole-shaped opening in the upper or outer material, A, and also serves to hide the edges of the key-hole-shaped opening, and also protects these edges against being Worn by the contact of the buttons, which latter feature becomes very important when the part A is made of cloth.

It will also be seen that, by my method of putti ng these parts together and subsequently cutting the button-slits in the button-ily lining by means of a cutting-tool introduced through the button-hole lining or re-enforcement, l insure absolute accuracy in the location of the button-slits b.

I usually secure the parts together by means of some adhesive material, and also by a rovir ofstitching extending around'outside the bead but either the adhesive material or the parting from the spirit of my invention.

l am aware that I am not the first to interpose a tough inelastic re-enforcement between the upper and the lining of a button-ily; but as such device had been employed prior to the date of my invention it consisted of a thin piece of leather, dat upon both sides and imperforate, for which reason it is apparent that it contained nothing correspon ding to my combination of the button-hole lining G, having the bead c' and slit c, with a button-hole provided with a key-hole shaped opening, a. Hence it was impossible that in such earlier constructions the position of the button-slit in the lining B relative to the key-hole-shaped ICQ opening a could be determined by the position of the button-hole re-euioreelnent, the posicion of which, in turn, is determined by the bead 0.

Vhat I claim is- The herein-described method of making hutton-holes-that; is to say, by interposing a button-hole lining or re-enforcelnent, C, having :L bead, 0, and button-slit o', between an upper, A, having a keyhole-shaped opening, a, there- 1o in, and an imperforate lining, B, the bead heing inserted in the opening a, and afterward making :L button-slit in the lining B opposite the slit c', substantially as set forth.

1n testimony that I claim the foregoing as my own I aix my signature in presence of 15 nwo witnesses.
