TABLE-CASTER.

SPECIFICATION forming part of Letters Patent No. 299,689, dated June 3, 1884. Application filed January 2|, 1884. (No model.)

To It whom it may concern Be it known that we, DANIEL SHERWOOD and GEORGE D. DUDLEY, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvementin Table-Casters, of which the following is a specification.

Our improvement relates to table-casters for domestic use; and it consists in forming and uniting the parts of the same together out of smooth wire, so as to leave no exposed cracks or joints in the same, substantially as hereinafter described.

In the drawings, Figure 1 is an elevation of a table-caster constructed according to our in- Fig. 2.is a plan view of the rings, showing their mode of construction. Fig.3 is a side View of the wire as prepared to make the rings.

A A are the legs of the stand, twisted together at a, and bent on each side of the twist to form the handle of the caster.

B B are the rings,soldercd to the legs at b b, as hereinafter described. These rings are made, as shown in Fig. 2, so that each pair of opposite rings are formed from the same piece of wire and connected across by the bridge part c.

D is the piece of wire from which each pair of rings, with their connecting bridge-piece, is made. The ends of this piece of wire at d d are cut or grooved out, so as to fit around or overlap the parts of the wire against which they abut when bent into the rings, as shown in Fig. 2, thus forming stronger and tighter joints, .which do not show when the caster is completed. Thebridge pieces a c serve to give three points of support to each ring, the other two being where the ring is soldered to the legs on each side at I2 I). The rings being made and secured together, as shown, by any suitable means, substantially as shown in Fig.

2, and the legs inserted at the places marked a a in Fig. 2, the whole, being substantially in the positions shown in Fig. 1, is dipped in molten metal and coated and solderedtogether at the same time, thus forming a firm and durable structure of smooth wire, and without spaces or interstices of irregular character to catch and retain dirt or liquids, as in twistedwire casters. As each ring is held at three points, it is able to support the weight placed in it. The crossing-place of the bridge-pieces c c is also a source of additional strength to, each ring, as the pieces are there soldered to gether,

What we claim as newand of OllllIlVGHbiOll 1. Awire table-caster formed of the smooth legs A A and smooth wire rings B B, connected together and to said legs by soldering metal.

2. The wire rings B B and bridge-piece 0, formed of a single continuous piece of smooth wire, substantially as described.

3. The wire ring B, formedwith the bridgepiece 0, of a single piece of wire, and having its grooved end d overlapping the wire against which it abuts, substantially as described.
