IMPROVE!) FURNITURE-(MISTER.

The Schedule referred to in these Letters Patentand making part o! the lame.

To all whom it may concern.-

Beit known that I, STEPHEN CHANDLER, of the city, county, and Sta-te of New York, have invented a new and useful Improvementin Furniture-Casters; andi do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art tomake and use the same, reference being had to the accompanying drawing, forming part of this specification, in which drawing- Figure l represents la vertical central section of this invention. A

Figure 2 is an inverted plan of the same.

Similar letters indicate corresponding parts.

This invention consists in an improvement in casters, iu which the friction-balls are mounted on a rod, which is supported by wires -hung ou 'hooks projecting from the stock or body of the caster, and continued into fingers which prevent the ball from falling from the socket, as will be hereinafter more fully described.

In the drawing, the letter A designates the body or stock of lny caster, which is castof iron or brass, or made of any othersuitable material, and which forms a hemispherical socket, a, to receive the ball or sphere- B, which is madeof hard wood or any other suitable material.

From the edge of the socket a rises a series of lugs, b, which is provided with semi-cylindrical cavities, c, to form the bearings for the circular rod d, on which is ,mounted a series of anti-friction rollers, e. 'lhese rollers are set each between two of the 'lugs b, and they bear against the periphery of the ball B, so as to prevent the same from rubbing against the edge of the socket a. l

'The rod d is retained in its semi-cylindrical bearings by 'means of wires, f, which are hitched on tohooks ranged that no extra. labor is required in putting them together.

'lhe stock A is bored out ina longitudinal direction, to receive a rod, C, the lower end of which is rounded oii to form a bearing-point for the ball B, and to prevent said ball' from coming in contact with the inner surface of the socket, as shown in iig. 1.

Said rodextenrls beyond the stock, audits lrpper end is provided with a screwtl1read, fi, which screws into a nut, D, let into the leg orother part of a piece of furniture to which the casteris to be attached. By these means, a firm hold is provided for the castel', and my caster can be readily applied to furniture of any description.

What I claim as new, and desire to secure by Letters Patent, s-` v v v.

The suspended wires f, carrying the ro d on which the friction-rollers are mounted, and continued into fingers 7:-, in combination with lugs b, having open cavities to receive said rod, when the parts are constructed and operate together as described.
