Abstract
Abstract An alternator is adjustably mounted adjacent a hinged end of an elongated hingedly mounted support carried by a vehicle and the alternator has a driven sheave fixed to its rotor. An idler sheave assembly is carried adjacent the opposite end of the elongated support and at least one power transmission belt is operatively connected between the driven sheave and the sheave assembly. A driver sheave is mounted against the end of a rotatable axle of the vehicle for rotation therewith and at least another power transmission belt is operatively connected between the driver sheave and the sheave assembly. A spring assembly yieldingly urges the support about its hinged end thereby moving the sheave assembly away from the driver sheave and placing constant yielding tension on the other belt thereby assuring that the alternator is driven in an optimum manner by the driver sheave.

Claim 9
Dependent Claim
40 words
A drive apparatus as set forth in claim 1 in which said sheave assembly is in the form of a step sheave assembly which for a given speed of said driver sheave provides a different speed for said driven sheave.
Claim 10
Dependent Claim
23 words
A drive apparatus as set forth in claim 1 in which said first and second belt means each comprises a plurality of belts.
Claim 11
Dependent Claim
26 words
