Patent ID: 6971410

Claim:
A self-contained portable drum dosing system, comprising: a) a main frame, the main frame comprising a loading end and a steering end remote from the loading end, a set of wheels mounted to and below the main frame for facilitating the movement of the main frame from one location to another; b) an outer mast assembly extending generally horizontally from the main frame at the loading end, the outer mast assembly comprising a pair of legs at the loading end, each of the legs having a longitudinal centerline, extensions of the longitudinal centerlines intersecting generally at the post assembly to form an angle between the legs such that a generally V-shaped spacing between the legs is formed at the loading end, the angle being sufficient respect to the legs to permit the legs to dispose the main frame near a drum; c) an upstanding post assembly extending upwardly from the main frame at the outer mast assembly, the post assembly comprising: i) a fixed guide post, ii) an upper clamping mechanism for releasably engaging the chime of a drum, the upper clamping mechanism being movably mounted to the fixed guide post and being disposed in the spacing between the legs for selective vertical movement up and down with respect to the fixed guide post, d) a pump mechanism comprising a pump, a dip tube attached to the input side of the pump and a discharge line attached to the output side of the pump demountably mounted to the clamping mechanism, demountably mounted to the drum, moveably mounted to the fixed post, or mounted to the main frame; and e) a lifting mechanism selectively controlling the vertical movement of the upper clamping mechanism to thereby permit a drum to be engaged by the system and then be conveyed from one location to another.
