CASTER.

SPECIFICATION forming part of Letters Patent No. 321,859 dated July 7, 1885.

Application filed January 5, 1885.

T0 aZZ whom it may concern:

Be it known that I, JAMES \V. SEE, of Ham ilton, Butler county, Ohio, have invented certain new and useful Improvements in Casters, of which the following is a specification.

This invention relates to furniture-casters, and it will be understood from the following description, taken in connection with the accompanying drawings, in which- 1 Figure 1 is a side elevation, part section, of a furniture-caster embodying my improvement; Fig. 2, a perspective view of the movement, shown separately; and Fig. 3, a diametrical section through one of the disk-piles.

In the drawings, A represents the casterwheel 5 B, the horn; G, the stem; D, the socket for the stem; E, a box or cup at the lower end of the socket; F, vertical rivets arranged in circumferential series equidistant from the axis of the stem; G, piles of independent disks fitted to revolve loosely upon the rivets and bear peripherally against the stem; H, a pair of plates fitted to carry the rivets and form the frame parts for the movement,which thus forms an integral structure adapted to seat in the socket-cup; and I, Fig. 3, hubs struck up upon the top and bottom disks of the pile.

The circumferential series of disk-piles form anti-friction wheels for the stem-bearing. The disks G are accurately punched from sheet metal. They may be punched from the scrap formed in punching the plates H, and they may be punched at the same punching-stroke with these plates, whereby the cost of the disks, both as to material and labor, is practically reduced to zero. Each disk being free to revolve independent of its contiguous neighbor, the usual peripheral flattening is avoided, it being hardly possible for all of the disks of a pile to remain stationary and be subjected to the rubbing action of the spindle at one time.

(Modem WVith solid anti-friction wheels it is common for a Wheel to stand still and have a fiat or concave place worn into its periphery by the spindle, thus destroying the device.

I11 Figs. 1 and 2 the piles are formed of three disks, while in Fig. 3 I show a pile formed of four disks. The number employed is immaterial.

For extremely delicate casters it may be found desirable to provide the piles with hubs, so as to avoid side friction far from the center of the disks. Such hubs may be formed by striking up the outside disks, as clearly shown in Fig. 3.

Much that has been described is old and not original with me.

I also desire to state that skate-wheels and caster-wheels have been formed of a number of layers of rawhide or the like permanently secured together by cement, nails, rivets, or clamping-flanges, so as to form an integral structure.

I do not claim wheels so constructed as of my invention.

I claim as my invention- 1. In a caster, the anti-friction wheels formed by the combination of the metallic disks G into piles, each disk of a pile being independent of its fellow disks, substantially as and for the purpose set forth.

2. In a caster, the anti-friction rollers formed by the combination of the disks G into piles, the outer disk of each pile being provided with the struck-up hub I, substantially as and for the purpose set forth.
