- IMPROVEMENT IN SOCKETS FOR CONNECTING SPOKES AND FELLIES.

Specification forming part of Letters Patent No. 117,799, dated August 8, 1871.

To all whom it may concern:

Be it known that I, SAMUEL MITCHELL, of Lima, in the county of Livingston and State of New York, have invented a certain new and useful Improvement in Sockets for Connecting Spokes with Fellies, of which the following is a specification This invention consists in constructing the iron socket which unites the spoke to the felly with slits or openings in the lower end for the insertion of a wedge, which has the double effect of expanding the spoke in the socket and the socket in the felly, as hereinafter described.

In the drawing, Figure l is a section of my improvement Fig. 2, a perspective view of the parts separated.

A represents one of the spokes; B, the felly; and C, the cast-iron socket which connects the parts. This socket is preferably made of malleable-iron, of sufficient length to extend through or nearly through the felly, being made hollow to receive the tenon of the spoke. It is made with an exterior shoulder, a, which rests upon the top of the felly, and with an interior shoulder, b, which receives the shoulder of the spoke. This prevents any splitting of either the felly or the spoke. The lower end of the socket is formed with long slits or openings, f f, which extend longitudinally through .both sides. When the spoke and socket are fitted in the felly a wedge, g, is driven reversely into both the tenon of the spoke and the slits f f, expanding them both outward in the felly-socket, thereby holding both firmly in place. This arrangement prevents split ting of the felly by making the spoke-tenon of, smaller size than usual.

The special featur'e of novelty in my invention consists of the slits f f, by which the double effect of expanding the spoke in the iron socket and the socket in the felly is produced, thereby holding both parts. The socket without the slits has proved impracticable, for although the spoke could be tightened in the socket itself, the latter could not be tightened in the felly when entire. When made of malleable iron the thin end of the tube with the slits in will readily expand, and remain perfectly tight under all circumstances. I thus make practical and effective a device which has before been inoperative and comparatively worthless.

I disclaim simply a tube connection; but

WVhat I claim, and desire to secure by Letters Patent, is

The socket C, when formed with the slits ff for the insertion of a wedge, whereby the double effect of expanding the spoke in the socket and the socket in the fell y is produced, substantially as herein shown and described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

SAML. MITCHELL.
