GEVEDRA B. SHELDON, OF NEW YORK, N.Y.

IMPROVEMENT IN FURNITURE-CASTERS.

Specification forming part of Letters Patent No. 139,619, dated June 3, 1873; application `filed May 19, 1873.

To all whom it may concern: i

Be it known that I, CE1/EDRA B. SHELDON, of the city, county, and State of New York, have invented a new and usetul Improvement in Furniture-Casters, of which the following is a specication:

The brackets or horns of ordinary furniturecasters are made of cast metal, and are consequently' heavy and expensive. The socket or box is also usually cast, turned, and bored with the weight of the furniture bearing upon the end of the pin. My present invention consists of a collar on the under side of the horn which is formed in punching the pinhole, which gives the requisite thickness and strength to the horn at that point, and enables me to stamp or strike out the horn from sheet metal. It also consists in a flanged socket, stamped or struck up.

In the drawing, Figure l is a side view of the castor. Fig. 2 is a vertical section of Fig. 1 on the line w x. Y

Similar letters of reference indicate corresponding parts.

\ tion-balls F, and'is attached to the piece of furniture by means of screws through holes in the ilange Gr. The pin C is provided with a head, H, which prevents the caster from dropping from the socket when the furniture vis raised from the iloor. The other end of this pin, shouldered at @,is riveted onto the collar E at b, as seen in Fig. 2. By means of the collar E sufcient thickness is given to allow the pin to be rigidlyand durably attached to the horn, and it enables me to cut or stamp the horn from sheet metal of suitable thickness. When this horn is made in the usual way (that is, of cast metal) the horizontal or top part is necessarily twice as thick as the rest of it, and it is all much heavier, and consequent-ly more expensive `than when it is made of sheet or wrought meta-l. The socket D is struck up in dies by which the expense of boring and turning is avoided. In thel manufacture of furniture-casters cheapness and durability are objects of the irst importance. By stamping out the horn and the flanged socket, and combining them with the headed pin in the manner described, these objects are secured. y

Having thus described my invention, I claim as new and desire to secure by Letters Patentf l. The socket D and ilange G made in one piece of struck-up sheet metal, as and for the purpose specified.

2. The horn A and collar` E made in one piece of struck-up sheet metal, as and for the purpose specified.

3. The struck-up sheet-metal socketV and flan ge D G combined with the struck-up sheetmetal horn A with collar E, by means of the" wrought-iron pin C, substantially as described.
