Abstract
Abstract A mechanized system for the automatic loading and unloading of a vehicle of the front loading type. The vehicle is provided with a cab which will swing 90* to the left thereof and a bed which is movable longitudinally on the vehicle''s chassis. Powered rollers on the floor of the bed move the cargo into or out of the vehicle. A switch in front of the vehicle''s cab will activate means to open the door of a warehouse when the cab is in close proximity to the warehouse dock. The cab is swung to the left of the vehicle and the bed moved onto the dock to the warehouse door. All operations are controlled by the driver and he is protected from inclement weather at all times. The system eliminates the need for fork lifts in loading or unloading.

Claim 1
Independent Claim
175 words
In a mechanized system for the automatic loading and unloading of a cargo between a vehicle and a storage area, said storage area including a warehouse, a closure door therefor and a loading dock in front of said warehouse, said system comprising a vehicle having a chassis, a bed having an open forward end mounted for longitudinal movement along said chassis, an operator''s cab carried by the forward end of said chassis and being adapted to swing 90* to one side thereof, means carried by the forward end of sAid chassis for adjusting the forward end of said bed relative to the height of said dock, means mounted in said chassis for extending said bed onto said dock and up to said door of said warehouse, means mounted in said bed for moving said cargo into and out of said bed, and means carried by said warehouse, said dock and said cab of said vehicle for opening said closure door of said warehouse when said vehicle has approached to a close distance from said dock.

Claim 4
Dependent Claim
38 words
A system as set forth in claim 1 wherein said means for extending said bed comprises at least one hydraulic ram pivotally connected at its rearward end to said chassis and at its forward end to said bed.
Claim 5
Dependent Claim
61 words
A system as set forth in claim 1 wherein said means for moving said cargo into and out of said bed comprises at least two parallel rows of rollers mounted on the floor of said bed, each row of rollers being separately power operated for rotation in either clockwise or counterclockwise directions whereby partial components of a cargo may be handled.
Claim 6
Independent Claim
90 words
A system as set forth in claim wherein said means to close said warehouse door comprises a motor in said warehouse and in driving connection with said door, a switch located in front of said dock and being in electrical connection with said motor and an extendable magnet operable from said driver''s cab and located in front of said cab whereby when said vehicle is in close proximity to said dock, said magnet may be extended to attract and close said switch to activate said motor and open said door.
Claim 7
Dependent Claim
37 words
A system as described in claim 1 wherein said dock comprises a raised platform having a height substantially equal to the level of the floor of said bed being covered by at least one flat metal plate.
Claim 8
Dependent Claim
