Abstract

Abstract A mobile vehicle having a container storage tunnel for storing a plurality of empty or filled containers and transporting them between a pick-up area and a dumping station. The vehicle includes a fork lift unit having a dumping mechanism with a bin clamp thereon for elevating and dumping a product from the bins or containers. The fork lift unit may lift the containers into positions to be stored in the tunnel, to be loaded on a flat bed truck to be dumped. When moved to the dumping position, the dumping mechanism tilts the containers in excess of 90* about pivot points adjacent the ends of the fork lift tines, and the clamp mechanism is activated to positively lock the container to the dumping mechanism during this tilting operation. The empty containers may then be lowered directly onto the ground or the flat bed of a truck, or may be lowered upon a carriage which moves at least several containers into the storage tunnel.

Claim 2
Independent Claim 335 words
An apparatus for dumping articles from containers having front, side and rear walls and a rear abutment surface comprising: a pair of transversely spaced fork lift tines having free ends, tine supporting means including means for raising and lowering said tines between a pick-up position and a dumping position along a generally vertical path, a dumping mechanism carried by said tine supporting means and having a pair of transversely spaced container supporting bars normally disposed in a horizontal plane, means for pivotally connecting said bars on the tines immediately adjacent the free ends of said tines, said dumping mechanism including a normally upright frame including upright members secured to the other ends of the supporting bars and having a container abutting surface for engaging the rear abutment surface of the container, container clamping means pivotally mounted on said upright frame and including a transversely extending clamp bar, means for pivotally actuating said clamping means for moving said clamp bar between an inactive position spaced from and disposed above the container to an active position engaging the front wall of the container, and means for pivoting said dumping mechanism about the free end of said tines when said clamping mechanism is in its active position to dump articles from the containers, further, said tine supporting means is mounted on a mobile vehicle; said mobile vehicle including a storage tunnel for storing a plurality of containers; said upright frame having an opening above said container abutting surface when said dumping mechanism is in the pick-up position of sufficient size to allow containers to move therethrough, a carriage on said vehicle movable into and out of said generally vertical path of movement of the containers; and power means for moving said carriage into the path of movement of the container as said tine supporting means is lowered from said dumping position toward said pick-up position to deposit the container on said carriage when extended, and for thereafter retracting said carriage with the container thereon into said storage tunnel.
Claim 3
Dependent Claim 27 words
An apparatus according to claim 1 wherein hydraulic means are provided to tilt said tine supporting means through a limited arcuate range from a normally vertical position.
Claim 4
Dependent Claim 318 words
Container handling apparatus which comprises a mobile vehicle having a vertically movable fork lift unit thereon provided with transversely spaced longitudinally extending fork lift tines and means for raising and lowering said tines, the improvement comprising a container dumping mechanism on said fork lift unit, a pair of transversely spaced container supporting bars on said unit normally disposed in a horizontal plane and pivotally connected to the free ends of said tines, a pair of normally vertically extending members connected to the other ends of said bars and transversely spaced apart a greater distance than said container supporting bars and said tines, said vertical members including inwardly directed arms having upright container abutting surfaces adjacent the junction of said vertical arms with said horizontal container supporting bars, generally U-shaped container clamping means connected to said members for pivotal movement about a transverse axis disposed above the upper surface of a container supported on said container supporting bars, means for pivoting said clamping means from a position spaced from the container to a position firmly engaging the wall of the container over which articles are dumped, and means for pivoting said dumping mechanism from said normal position to a dumping position while said clamping means firmly clamps the container against said upright container abutting surfaces, further, said vertically extending members are spaced apart a sufficient distance at a position above said container abutting surfaces for allowing dumped containers carried by said dumping mechanism to pass there-through, means defining a container storage tunnel in said mobile vehicle, and carriage means on said vehicle mountEd for movement between a retracted position within said tunnel and an extended position in the downward path of movement of empty containers after they have been dumped for intercepting said empty containers and for transferring said empty containers directly into said storage tunnel, and means for moving said carriage between said retracted and said extended positions.
