Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
In a transmission powered air-conditioner compressors apparatus, the combination of a plurality of air-conditioner compressors, which are installed at a side of a transmission of an automotive truck, such apparatus including a power takeoff unit, between said transmission and said air-conditioner compressors, said power takeoff unit including an output drive shaft, having a pair of pulleys affixed thereupon, one of said pulleys having an endless belt therearound, which extends around a pulley affixed upon a shaft of a first of said air-conditioner compressors, another of said pulleys, of said power takeoff output drive shaft, having an endless belt therearound, extending around a pulley affixed upon a shaft of a second of said air-conditioner compressors, said compressors being supported from an eye beam secured by bolts to a beam secured to said transmission.
