Mobile drum filling assembly

A portable device that may be moved adjacent a bulk liquid holding tank having a liquid inlet and liquid outlet to sequentially dispense predetermined weighted quantities of said liquid into a plurality of drums, each of said drums being of the type that includes a bottom and an upwardly disposed head that has a bung hole therein that may be removably closed by a stopper, said device including:

• a. an elongate rectangular portable bed having a first forwardly disposed end and a second rearwardly disposed end, and first and second longitudinal sides;
• b. a frame work extending upwardly from said bed;
• c. first, second and third elongate conveyors having first forward ends and second rearward ends, said conveyors supported from said frame work in elevated positions above said bed and extending longitudinally relative to the latter, said first conveyor adjacently disposed to said first side of said bed, said second ends of said conveyors adjacently disposed to said second end of said bed, said first conveyor angularly disposed to the extent that drums placed on said second end thereof move by gravity to said first end thereof, and said second and third conveyors angularly disposed to the extent that drums placed on said first ends thereof move by gravity to said second ends thereof;
• d. a first conduit removably connectable to said liquid outlet of said tank;
• e. power-operated means for establishing a sufficient differential in pressure between liquid in the interior of said tank and the interior of said first conduit that liquid in said tank will flow into said first conduit;
• f. an engine on said bed for driving said power-operated means;
• g. first and second laterally spaced scales that have first and second laterally spaced weighing platforms that are supported from said bed adjacent said first end thereof, said first and second weighing platforms longitudinally aligned with said second and third conveyors and disposed adjacent said first ends thereof;
• h. a horizontal floor supported from said frame work adjacent said first and second scales on which an operator may stand to sequentially remove drums from said first end of said first conveyor and place them on said first and second weighing platforms to be filled with said predetermined weighed quantities of said liquid, with said drums on said first and second weighing platforms after having said predetermined weighed quantities of said liquid dispensed therein having said stoppers disposed in said bung holes, and said operator moving filled drums from said weighing platforms onto said second and third conveyors to permit said filled drums to coast by gravity to said second ends of said second and third conveyors;
• i. a horizontal platform supported by said frame work adjacent said second end of said first conveyor on which a person may stand to move empty drums onto said first conveyor and to tighten the stoppers in bung holes of filled drums that move towards said second end of said bed on said second and third conveyors;
• j. an elevated valved dual hose assembly above said first and second weighing platforms that receives liquid from said first conduit, said dual hose assembly including first and second tubular valved portions that extend into said bung holes of first and second drums on said first and second weighing platforms to permit said first and second drums to have said liquid concurrently dispensed thereinto from said first conduit;
• and
• k. second means operatively associated with said dual hose assembly for preventing fumes from said liquid being dispensed into said drums on said first and second weighing platforms escaping to the ambient atmosphere.
