Patent ID: 7618000

Claim:
A powering system for a vehicle carried paper shredder, the vehicle having an frame with an engine with speed control at a forward position, a two speed rear differential at a rear position, a two piece segmented drive line having a forward drive line shaft and an irrotatably interconnected rearward drive line shaft interconnecting the engine and differential, a pneumatic system, and a storage area for shredded paper, and the paper shredder having a hopper for storage of unshredded paper, a mechanism to load unshredded paper into the paper shredder and a mechanism to unload shredded paper from the paper shredder, the powering system comprising in combination: a middle drive line shaft, irrotatably carried between the forward drive line shaft and the rearward drive line shaft, and irrotatably carrying a drive pulley; a main drive belt, communicating between the drive pulley carried by the middle drive shaft and a slave pulley irrotatably carried by a power takeoff jack shaft journaled in a power takeoff assembly carried on the vehicle frame, to drive the power takeoff jack shaft; a belt tightening pulley adjacent the main drive belt between the drive pulley and the slave pulley, the belt tightening pulley journaled in the power takeoff assembly and movable by expansion and contraction of an airbag carried in an airbag housing of the power takeoff assembly and controlled by the vehicle pneumatic system to selectively remove slack in the main drive belt responsively causing the main drive belt to operatively engage with the drive pulley to communicate motion of drive pulley to the power takeoff jack shaft; a gear range selector carried by the two speed rear differential, the gear range selector having mechanical means to stop and maintain the gear range elector in a null position between gear ranges whereat rotation of the drive line is not communicated to the rear differential; and an electrical powering system having two batteries interconnected in series to increase amperage potential supplied to electric motors powering the mechanisms to load unshredded paper and to unload shredded paper, and electrical switching means to control polarity of current supplied to the motors to selectively reverse motion of the motors.
