UNITED STATES PATENT OFFICE.

O. H. DENISON, OF BRATTLEBOROUGH, VERMONT.

IMPROVEMENT IN MODE OF ATTACHING HUBS TO AXLES.

Specification forming part of Letters Patent No. 33,577, dated October 29,1861.

To all whom it may concern:

Be it known that I, C. H. DENISON, of Brattleborough, in the county of \Vindham and State of Vermont, have invented a new and Improved Mode of Attaching Hubs to Axles, designed specially for childrens carriages; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure l is a longitudinal sect-ion of a hub and axle, the former being secured on the.

latter according to my invention. a; 00, Fig. 2, indicates the plane of section; Fig. 2, a section of the hub taken in the line y y, Fig. 1; Fig. 3, an' external View of the back part of the hub and a portion of the axle.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to obtain a very simple, cheap, and durable means for securing hubs on the axles of childrens vehicles; and it consists in having a rod fitted longitu'diiiallyin the arm of the axle and provided at its outer end with a button attached eccentrically to: it, the inner end of the rod being provided with an arm or crank for turning the rod and thereby adjusting the eccentric, which in a certain position retains the hub on the axle, as hereinafter fully shown and described.

To enable those skilled in the art to fully understand and construct my invention, I

' will proceed to describe it.

A represents thehub, and B the arm of the axle C, on which arm the hub is placed and allowed to turn freely. These parts may be constructed in the usual way.

D is the hub-band, placed, as usual, on the front end of the arm. In the front end of the hub there is a circular recess o (shown in Figs. 1 and 2,) the inner surface of the recess and the end of the arm being flush with each other.

In the upper part of the arm B there is made longitudinally a groove E, in which a rod F is placed or fitted and allowed toturn freely. On the outer end of this rod F there is placed eccentrically a button G, which when turned down will be free from the end of the hub, and consequently within the area of the end of the arm B, as shown in red in Fig. 2 and in black in Fig. 1, and when turned no will lap or project over the end of the hub within the recess a, as shown in black in Fig. 2. On the inner end of the rod F there is an arm or crank b, by which the rod is turned, and consequently the button. When the arm or crank 12 is turned in the position shown in red, Fig. 3, the button G has a downward position, as shown in red outline in Fig. 2, and the hub may be withdrawn from the arm of the axle, and when said arm is turned as shown in black the button G has an upward position and overlaps the end of the hub, and consequently retains the hub on the arm. Thus by this simple arrangement, which may be applied at a small cost and without the liability of getting out of repair, the hub may be secured on the axle and readily detached therefrom when required.

The rod F may be prevented from casually turning by means of a pin a, passing through a-staple b on the axle.

' Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The rod F, fitted in the arm B of the axle C, and provided at one end with the eccentric or button G and at the opposite end with an arm or crank b, as and for the purpose. herein set forth.
