No. 242,648. Patent ed June 7,1881.

UNITED. STATES PATENT OFFICE.

GEORGE W. HORNE, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO WILLIAM IRELAN, SR.,-'OF SAME PLACE.

CASTER.

SPECIFICATION forming part of Letters Patent No. 242,648, dated June 7, 1881. Application filed April 5, 1881. (No model.)

To all whom it may concern Be it known that I, GEORGE W. HORNE, a subject ofthe Queen of Great Britain, residing at San Francisco, in the county of San Fran- -cisco and State of California, have invented In the annexed drawings, in which like letters indicate like parts in the several views, Figure l is a plan view of the undersurface of the caster, partly in section and with the under ring removed. Fig. 2 is a section on the line a: m. Fig. 3 is aview of the upper surface of the center ring or plate; and Fig. 4 is a view of the under surface of the upper plate with lower ring attached.

The body of the caster consists of a flanged plate, A, having a stem or pintle, A. This plate is provided on its under surface with recessed lugs a a, that are cast against theinner side of the flange a, and form wedge-shaped bearings for the journals of therollers B. These rollers are made tapering toward each end, and are supported by their journals 1) in the bearings a, a. When in position the rollers are held in place by the lugs or caps cc on the ring 0. After the ball D is put in position it is secured by the ring E, which is connected with the upper flanged plate, A, by bent arms 6 e e, that are fastened thereto by screws d. These arms also hold the ring 0 in place.

This caster is particularly adapted foruse on piano-legs and other heavy articlesof furniture.

The arrangement of the rollers B, which are preferably five in number, is such that friction of the same with the surface of the ball D is greatly diminished and the operation of the parts .rendered more easy and eflicient than when a greater or less number of the rollers are employed. The rollers are also superior to wheels, as they will revolve freely, whatever the direction may be in which the caster is moved.

The frame of the caster may be made of any suitable metal, in two or more castings, as desired, the center ring, (3, being cast separately or in connection with the ring E and arms 6, as found convenient.

If desired,theringE maybe dispensed with, the ball D being then held'in place by the bent arms 6 alone, which, in that case,may be cast either upon the plate A or ring 0. By'employing the ring E, however, a better effect is produced, as the arms 6 are thereby strengthened, and their lower ends prevented from becoming entangled with or abrading the carpet or other surfaces over which the caster is rolled.

The caster is preferably attached to the furniture by means of a stem or pintle in the usual manner 5 but the pintle may be dispensed with and the caster attached by screws passing-through the plate A.

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

The combination of the flanged plate A, having bearings a, rollers B, center ring, 0, provided with caps 0, ball D, lower ring, E, and bent arms 6, substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE WILLIAM HORNE.
