Abstract
Abstract A hub odometer having a protective case adapted to be mounted axially on an axle cap of a vehicle with a substantially cylindrical carrier plate rotatably mounted in the case for supporting a counting mechanism having figure wheels. The shaft of the figure wheels is mounted transversely of the axis of rotation of the case within the carrier plate, and a reduction gearing transfers the relative rotation of case and carrier plate to the figure wheels. At least one ball of heavy metal is provided, the ball being movably positioned in substantially diametrical opposition with respect to the case axis to the figure wheels, the ball being heavier than the counting mechanism.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
151 words
A hub odometer comprising a cylindrical case with a rear wall adapted to be mounted axially on the axis of rotation of a wheel of a vehicle, a carrier plate mounted for rotation in said case coaxially with the axis of the wheel, said plate supporting a counting mechanism, said counting mechanism mounted on said plate to one side of the axis of rotation of said plate, spur gear means spaced from said plate coupling the case to the counting mechanism, at least one ball being movably positioned in substantially diametrical opposition with respect to said case axis to said counting mechanism, an arcuate guiding path on said plate of less than 180° diametrically opposite said counting mechanism, said ball being positioned between a pair of pressure springs positioned within said guiding path, and said spur gear means is positioned within the space between the guiding path and the counting mechanism.
Claim 2
Dependent Claim
151 words
A hub odometer comprising a cylindrical case with a rear wall adapted to be mounted axially on the axis of rotation of a wheel of a vehicle, a carrier plate mounted for rotation in said case coaxially with the axis of the wheel, said plate supporting a counting mechanism, said counting mechanism mounted on said plate to one side of the axis of rotation of said plate, spur gear means spaced from said plate coupling the case to the counting mechanism, at least one ball being movably positioned in substantially diametrical opposition with respect to said case axis to said counting mechanism, an arcuate guiding path on said plate of less than 180° diametrically opposite said counting mechanism, said ball being positioned between a pair of pressure springs positioned within said guiding path, and said spur gear means is positioned within the space between the guiding path and the counting mechanism.
Claim 3
Dependent Claim
33 words
An odometer as in claim 1 wherein the counting mechanism has a plurality of figure wheels rotatably mounted on a shaft which is mounted transversely of the axis of rotation of said plate.
Claim 4
Dependent Claim
15 words
An odometer as in claim 1 wherein two balls are positioned between said pressure springs.
Claim 5
Dependent Claim
14 words
An odometer as in claim 1 wherein said pressure springs are helical coil springs.
Claim 6
Dependent Claim
22 words
An odometer as in claim 1 wherein the material of said ball is diamagnetic that has a higher specific gravity than steel.
Claim 7
Dependent Claim
28 words
An odometer as in claim 2 wherein the spur gear means is coupled through reduction gears, bevel gears and a stepping mechanism to the least significant figure wheel.
Claim 8
Dependent Claim
24 words
An odometer as in claim 6 wherein an axle of said spur gear means is integrally formed from the wall of said carrier plate.
Claim 9
Dependent Claim
53 words
An odometer as in claim 6 wherein the bearings are formed integral with the wall of the carrier plate and the bearings of the counting mechanism are pockets open in the direction of rotation of the axis of rotation of said case, said pockets being at least partly closed after introducing said axles.
Claim 10
Dependent Claim
39 words
An odometer as in claim 6 comprising a front plate secured in spaced relation to said carrier plate and having a window for viewing said figure wheels, said front plate being secured by studs extending from said carrier plate.
