NTTE STATES GEORGE H. IIOIVELL, AOF SIOUX CITY, IOIVA;

UPHOLSTERING-PIN.

SPECIFICATION forming part of Letters Patent No. 575,157, dated January 12, 1897. Application filed May 8, 1895. Renewed October 6, 1896. Serial No. 608,068. (No model.)

To all whom t may concern:

Be it known that I, GEORGE'I-I. HOWELL, of Sioux Oity, in the county of W'oodbury and State of Iowa, have invented certain new and useful Improvements in Upholstering-Pins; and I do hereby declare the following to be a full, clear, and exact description of the in vention, 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 upholstering-pins.

I-Iitherto it has been the practice in upholstering lounges and similar articles of furni ture to employ ordinary shanked buttons and to sew them by means of needle and cord. This is a slow and laborious method, because after undergoing the difficulty of sewing the cord through the ends have to be drawn together and tied. In doing this the knot is liable to slip and some of the cords are drawn tighter than others. In consequence of these imperfections, which necessarily result from the old method, the work was unsatisfactory and unduly expensive. It is the object of my invention to obviate these defects; and my invention consists in a nail the shank of which is of considerable length and furnished with a head on one end and a point of more or less sharpness on the other end, in combination with a keeper comprising a thin disk having spring-catches formed thereon adapt` ed to pass over the nail-shank in one direction and lock themselves against backward movement. y

It further consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure is a view illustrating my improved upholsteringpin applied. Figs. 2 and 3 are detached views of the pin and the catch, respectively.

A represents the pin, the shank of which is pointed at one end and provided with a head at the opposite end. On this shank are placed a number of upwardly-projecting barbs l l l. These do not interfere in the least with the insertion of the pin, for the latter is taken between the operators fingers with the thumb on the head of the pin and the latter is inserted into the material to be fastened, Where it is held until the catch is applied.

B represents the catch. It consists in a thin disk of sheet metal having a hole 2 in the cen- 5 5 ter to receive the pin, and it is cut diagonally to form several spring-dogs 3 3, which yield readily to allow the barbs to pass and then spring back into place over the barbs to lock the catch in place. The hole 2 is of a size relative to the shank of the pin to prevent the dogs from springing` back to the plane of the body of the catch, the shank of the pin acting as the keystone ofan arch to keyand lock the dogs against yielding the slightest in the reverse direction, unless, of course, greater pressure should be applied, greater than the strength of the metal itself, which would cause the metal to break or bend and not merely spring aside. Hen ce the device is easily and quickly applied, it is a secure and effectual fastener, it greatly reduces the time usually consumed in upholstering a piece of furniture, and, above all and of the greatest consequence, lessens the cost of the article.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described, and pointed out in the claims,without departing from the spirit 'and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth; but,

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

l. The combination with a pin having a pointed end adapted to penetrate and find its way through the material to be fastened,I of a plate or disk having a hole extending therethrough wherein to receive the pin, and also provided with several slots extending radially from the hole whereby to form spring-jaws to engage the pin, substantially as set forth.

2. In upholsterers buttons, the button, the shank, the notches at 1, l, and the head B with its central perforation and the points between the slits, substantially as set forth.

3. In upholsterers appliances the button, its elongated shank, in combination with the head B with its perforation and its spring clutchingepoints, substantially as set forth.

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