IMPROVEMENT lN CASTERS FOR SEWING-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same.

I, HARRY JONES, ofthe Vcity of Richmond, county .of Wayne and State of Indiana, have invented a new -and improved Caster for Sewing-Machines, of which the following is a specification.

Nature and Object of the Invention. My invention relates to a castel' for sewing-machines, that portion' of the same by which it is attached to -themachine consisting of a castnnetal socket or shoe with a slot forthe te of the leg, and a set-screw, these being so constructed and arranged that, with the addition of a key or wedge placed in the groove on the inside of the leg, when the latter is so shaped, it is adapted to any of the various kinds of machines in use; the object sought being cheapness of construction, durability, and easy application.

General Description with reference to the Drawing.

Two casters are applied to a. machine, being attached to the rear legs.

A represents a quadrangular shoe or socket of thev the toe, by which the toe is made to support the cas- The caster is further secured by means of a setscrew, b, on the inside of the leg.

The legs of sewing-machines are usually grooved on the inside, in which case a wedge or key, e, shown by dotted lines in iig. 2, suited to the groove, is provided, against which the set-screw is tightened.

The position of the caster-wheels is thus at the rear ofthe machine, with their lower perpheries on about the same horizontal plane as the bottom of the foot, or slightly lower. The machine thus rests firmly on tie floor, with its table in a proper position.

In moving the machine the front legs are raised from the floor, throwing the weight of the machine on the casters, thus allowing it to he easily wheeled from one position to another.

' The only change that maybe necessary in applying the caster to diierentmachines consists in substituting one key for another, or, where there is no groove in the bottom' of the leg, in dispensing entirely with the key.

Having thusfully described my said invention,

What I claim, and desire to secure by Letters Patent, is-

The shoe A, provided with the slot for the toe and va set-screw, the latter being so'arranged asto operate against the key e,or inside of the leg, as described, and for the purpose set forth.

' HARRY JONES.
