To all whom it may concern:

Be it known that I, ,CUn'rIs Hossnr Verona, a citizen of the United States, residing in the city of Hartford, in the State of Connecticut, have invented certain new and useful Improvements in Odometers, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to the means for actuating hub odometers for motor and other vehicles, which are mounted within casings secured to or forming parts of the hubs of vehicles and rotate therewith, the actuation of the registering mechanism being effected through connections to the stationary axles upon which the wheels are mounted.

The invention is particularly concerned with the actuating connections and has for its object to provide mechanism by Which the register shall be driven in one direction only, while the actuating mechanism itself is reliable in operation and offers no great difiiculties in manufacture.

The invention will be more fully explained hereinafter with reference to the accompanying drawings in which'it is illustrated, and in which- Figure 1 is a view, partly in end elevation and partly in transverse section, of a wheel hub with the invention applied thereto. Fig. 2 is a view in section on the plane indicated by the line 22 of Fig. 1, looking in the direction of the arrows. Fig. 8 isv aview similar to Fig. 1 but with part of the frame of the actuating mechanism removed to show the constructionmo're clearly. Fig. 4 is a view in section on the plane indicated by the line 44 of Fig. 1, looking in the direction of the arrows.

In the several figures of the drawings enough of a wheel hub a is shown to enable the application of the invention to be under stood, a portion of the stationary axle, on which the wheel is mounted, being indicated at b in Figs. 2 and 4. The hub is shown as having formed integrally therewith a cap 0 which forms a register chamber a, separated from the axle chamber a by a plate 03 which is removably secured in the hub and supports the driving mechanism. The register 6 is attached to the inner face of the cap 0, which is provided with a glazed sightv opening 0 through which the register may be read. The present invention is not concorn with the construction of the I r itself, which may be of any suitable adapted to be actuated by the continuous if rotation of its driving shaft e. The latter has secured thereon a bevel geap whi h meshes with a bevel gear f one short shaft f, mounted in bearings in the plate d and in the frame member d. The shaft f also has secured thereto a ratchet wheel 7 which is engaged by a spring-pressed detent pawl 7' (shown in dotted lines in Fig. 1) and by a spring-pressed driving pawl f. The latter is mounted on a carrier 9 which is pivotally mounted on the shaft f and has connected thereto the link 9' of an eccentric h. The latter is secured to a shaft 71. which is mounted in suitable bearings in the plate d and frame member cl, with a suitable stufiing box (2 so as to exclude dirt and grease from the register chamber, and has secured thereto a gear k which meshes with a corresponding gear secured to the end of the I axle b. I

As the gear h" is held' from rotation and as the gear 7L revolves around the ear h, the eccentric it will be rotated about its axis, whether the vehicle wheel be rotated in one direction or the other, and will actuate the driving pawl f, thereby causing a forward rotation of the driving shaft 6 of the register e. mechanism is reliable but that, the gears k and it having a somewhat loose engagement, the driving mechanism is not' affected by relative displacement of the hub and axle and furthermore, as all parts of the driving mechanism except the gear h are supported by the removable plate d,'it is easy to assemble the mechanism.

It will be understood that various changes in details of construction and arrangement may be made to suit different conditions of use and that the invention, therefore, is not restricted to the precise construction she and described herein. I

I claim as my invention;

1. The combination with an axle and a wheel hub, of a register-supported by the hub, a shaft and eccentric, mounted eccentrically in the hub, an eccentric link, a ratchet wheel mounted eccentrically in the hub, a pawlcarrier and pawl, said pawl carrier being mounted concentrically with the ratchet wheel and connected to the link, a

It will be seen not only-that the bevel gear mounted concentrically with the ratchet wheel, a bevel gear meshing therewith and connected with the reglster, and

means whereby said shaft is actuated from the axle.

2. The combination with an axle and a wheel hub, of a register supported by the hub, a shaft and eccentric mounted eccentrically in the hub, an eccentric link, a ratchet wheel mounted eccentrically in the hub, a pawl carrier and pawl, said pawl carrier being mounted concentrically with the ratchet wheel and connected to the link, a

bevel gear mounted concentrically with the ratchet wheel, a bevel gear meshing therewith and'connected with the register, a gear on said shaft and a gear loosely engaging therewith and secured to the axle end.

This specification signed and witnessed this 10th day of January, 1911.
