ERSKINE L. BABCOCK, ()F CUYAHOGA FALLS, OHIO.

CASTER.

SPECIFICATION forming part of Letters Patent No. 257,144, dated May 2, 1882.

Application filed November 14, 1881.

To all whom it may concern:

Be it known that I, ERSKINE L. BABCOCK, of Cuyahoga Falls, in the county of Summit and Stateof Ohio, have invented a new and useful Improvement in Casters, of which the following is a specification.

My invention relates to thatclass of casters which are used in furniture, and in which the swivel or caster-horn turns on the pintle.

The object of my invention is to so form the upper part of the pintle that it will not turn in its socket or easily become dislodged therefrom.

In the drawings, Figure 1 is a side elevation. Fig. 2 is a vertical cross section at the dotted line in Fig. 1."

The swivel a of caster-wheel I) turns on the pintle 0 between the pintle-head and washer e. The part of pintle c on which swivel a turns is slightly enlarged to form ashoulder for washer c to rest on. The upper part of pintle 0, above washer c, is intended to enter a socket, s, in the furniture-leg f or other article to which the caster may be applied. The part of pintle c which enters the socket s is of cylindrical form to fit the socket, except that it is formed with flat corrugated sides 0 at and near its upper end, which is edged or pointed, that it may be driven into the wood at the upper end of the socket.

(N0 model.)

It is often necessary or desirable to use easters in connection with small legs of furniture,

which are liable to split if the caster-pintle be forced into the socket formed in the end of the leg. This danger is obviated in the use of my caster-pin by boring the socket s of a size to be fitted by the cylindrical part of pimle c, the pintle being retained in place by its thin or wedge-formed upper part, 0, being driven in the end of socket s. The upper part, 0, may be quite thin,and with sides nearly parallel, to avoid all danger of splitting the furniture-leg, as the lateral strain on the pintle is borne by its cylindrical part, and the principal office of the thin upper part, c, is to prevent the piutle from becoming dislodged from socket s or turning therein.

I claim as my invention-- A caster-pintle, 0, having its corrugated up per portion of a wedge-like form, suitable to be driven into the upper end of the socket in a furniture-leg, a part of the pintle within said socket being made cylindrical to fit the bore of and be laterally supported by the sides of the socket, substantially as described.
