IMPROVEMENT IN WAGON-HUB.

Specification forming part of Letters Patent No. 86.451, dated February 2, 1869.

To all whom 'it may concern: n

Be it known that I, NATHAN RrxFoRD, of Mansfield Centre, in the county of Tolland and State of Connecticut, have invented a new and Improved Wagon-Hub; and I do hereby declare that the lfollowing is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to a metallic wagonhub; and consists in certain details of construction, which will be fully described hereinafter.

In the drawings, Figure l represents a side elevation of my invention, with a portion of the flange broken away. IFig. 2 is a longitudinal vertical central section ofthe same.

To enable others skilled in the art to which my invention appert-ains to make 'and use the same, I will proceed to describe its construction and operation.

A represents the hub, with the box A cast in pipe form, as shown. a represents a clampiiange cast thereon at a suitable distance from one end, and al a ring also cast thereon, which is provided with the spurs or projections a2, as shown in the drawings.

B represents a loose flan ge, which iits snugly about the box and bears against the ring al. This iiange is provided with V-shaped concentric grooves c c upon its inner side, by means of which the sharp ridges c1 are formed. It has, however, smooth bearing-surfaces upon the inner side, where it rests against the ring al, and upon the outer sides, where it comes in contact with the nut D, at the point c2. This latter bearing-surface, it will be observed, is very small.

The nut D turns upon the inner end of the box, which is provided with a screw for that purpose. It is provided with the hexagonal band d, which extends beyond the box and forms the sand-band.

The operation will be readily understood.

The spokes, two of whichl should be formed with a depression corresponding to the spurs a2, are placed in position about the hub, their butt-ends resting upon the ring al, these ends being so constructed as to bear against each other, as shown. y

The loose flange B is now placed over the box and forced to its place by means of the nut D, the sh arp ridges cl indenting themselves into the spokes, and thus holding them until the tire is set.

The object of this construction is to secure for the flanges a large bearing-surface against the spokes, and at the same time have a small friction-surface between the lian ge and the nut, which secures it in place.

By this construction a man can easily, with an ordinary wrench, take the hub apart and insert a new spoke without removing the. tire or telly-an operation which is impossible in the ordinary form of metallic hubs.

I am aware that constructing a metallic hub with a loose collar secured by a nut is not new, and that I do not claim in itself 5 but,

Having fully described my invention, what I do claim, and desire to secure by Letters Patent of the United States, is-

The wagon-hub described, consisting ot the box A with flange a and ring al, with spurs a?, in combination with the loose iiange B with groove c, having the small bearing-surface c2 and nut D with sand-band d, the whole being combined and arranged as described, for the purpose set forth. I

This specification signed and witnessed this 21st day of December, 1868.

NATHAN RIXFORD.
