IMPROVEMENT IN CASTERS FOR SEWlNG-MACHINES.

. Specification forming part of Letters Patent No. 101,924, (lated April l2, 1R70.

To all lwhom, it 'may concern:

-Be it known that I, BENJAMIN F. RYDEE, of New York, in the county of New York and State of New York, have invented a new Improvement in Sewing-Machine Casters; and I do hereby declare the following, when taken in connection with the accompanying drawings and the lettersof reference marked thereon, to be a full, clear, and exact description of the same, and whichsaid drawings constitute part of this specification, and represent, in

Figure 1 a perspective view, and in Fig. 2 a

-vertical central section, showing the application ofthe caster to sewing-machine legs.`

This invention relates to a caster as a new article otl manufacture, constructed so as to be attached by a clamping device to the leg of a sewingmachine; and the invention consists in the construction of a yoke with lugs to receive the trnnnions of the wheel, the said `yoke formed to tit the leg of the machine at the foot, and provided with a clamping-bar, by which the yoke is bound to the leg ofthe machine, grasping it above the bottom.

A is the yoke, constructed so as to fit the leg ot' the machine at the foot, and provided with projecting arms B B to receive and support the wheel C, and to the yoke is tted a bar, D, secured by screws a.

l be set onto the leg E of the machine, and the clamping-bar, by means of the screw a upon the back side ot' thc leg, draws the yoke hard down and binds it lirmly to the leg, the wheel C being in such relative position to the yoke that it will lie flush, or very nearly so, with the oor, so that by slightly tipping the machine the weight is thrown onto the wheel, or when free the table will rest on the foot ofthe leg.l

In order to more securely hold the yoke in position, I form upon the lower edge of the clamp D a ange, d, projecting under the leg, as seen in Fig. 2.

For machines in which the leg is of different formtheyokemustbe constructed accordingly; but all machines ot' the same make are so nearly alike that one form or pattern for the yoke will lit the legs of all machines. I do not broadly claim the employment of a yoke, but

I claim as my invention- As an article of manufacture, the herein-described caster, consisting of the yoke A, with arms B B to support the wheel C, and provided with the clamping-bar D, the whole constructed so as to be applied in the manner described, and with or without the flange d.
