Abstract
Apparatus is disclosed for spraying liquids, preferably paint, directly from a paint container mounted on the apparatus, wherein an electric drive motor, pump assembly, and paint container shelf are attached to a wheeled frame assembly for portable movement without disconnecting the paint container from the pump assembly, and wherein electrostatic voltage discharges are prevented by means of a common electrical interconnection of all electrostatic voltage-developing components.
Claims6
Apparatus for spraying liquids from a container and for portable relocation to a work site without disconnecting the liquid coupling and spraying members, comprising:
- a. an L-shaped frame member having wheels mounted on axles near the intersection of the horizontal and vertical frame legs;
- b. a motor and pump assembly rigidly attached to the horizontal leg of said frame member;
- c. a liquid container shelf pivotally mounted along said frame member vertical leg and supported in a substantially horizontal position by said motor and pump assembly, whereby said shelf is elevated above said pump assembly and has its load-bearing center forward of said wheel axles;
- d. a suction hose and a recirculating hose attached to said motor and pump assembly and having means for attachment to said liquid container;
- e. spraying means, attached to said motor and pump assrmbly, for delivering sprayed liquid pumped by said motor and pump assembly;
- and
- f. electric circuit means for interconnecting said spraying container shelf to a common electrical potential.
A portable paint spraying apparatus having a motor-driven pump for withdrawing paint from a paint supply container and recirculating said paint and delivering said paint at elevated pressures for spraying from a spray gun, comprising:
- a. a frame assembly having a base portion for attaching said motor-driven pump thereto, and having an upwardly extending handle portion;
- b. a pair of wheels rotatably attached to said frame assembly and having their wheel surfaces extending below said base portion;
- c. a paint container shelf attached to said frame assembly at a position elevated above said motor-driven pump and projecting forwardly to position its gravitational center point forwardly of said wheels attachment point;
- and
- d. means for electrically interconnecting said paint container shelf and said motor-driven pump to a common voltage ground.
