Abstract

There is disclosed a portable, battery-operated pump apparatus.

Claims

1. A portable pump enclosure assembly comprising a canister and a canister lid, said canister having a liquid-tight partition therein dividing the interior thereof into a pump compartment to receive therein electrically energized liquid pumping means and a battery compartment to receive therein an electric battery, gasket means sealably interposed between said canister and said lid to establish a liquid-tight closure of said battery compartment, conductor means to conduct energy from a battery housed within said battery compartment to a pumping means housed within said pump compartment, and switch means located on the battery compartment side of said enclosure assembly and in circuit with said conductor means.

2. The enclosure assembly of claim 1 wherein said canister lid additionally comprises a carrying handle.

3. The enclosure assembly of claim 1 wherein said switch means is located on said canister lid.

4. The enclosure assembly of claim 1 wherein said switch means is submersible.

5. The enclosure assembly of claim 1 wherein said switch means is located on a carrying handle extending above said canister lid.

6. The enclosure assembly of claim 1 wherein A. the interior of said battery compartment comprises a plurality of asymmetrically spaced vertical sidewall ridges extending upwardly from the floor thereof to a substantially uniform height thereabove, and B. there is provided a removable battery platform having two major surfaces, said platform being adapted to rest on the upper edges of said vertical ridges in spaced relationship above said floor when one major surface of said platform is faced upwardly, and said platform being adapted when the other major surface of said platform faces upwardly to engage said asymmetrically spaced vertical sidewall ridges in sliding relationship.

7. The enclosure assembly of claim 1 wherein the floor of said pump compartment is displaced vertically upwardly from the lower margin of said canister, and an impeller chamber comprising an inlet and outlet depends below said floor, the bottom of said impeller chamber being spaced above said lower margin and comprising said inlet.

8. The enclosure assembly of claim 7 wherein said canister additionally comprises liquid intake means to provide for flow of liquid from outside said canister to said inlet.

9. The enclosure assembly of claim 8 wherein said intake means comprises strainer means to strain out solid foreign matter.

10. A portable, battery-operated liquid pumping device comprising:

A. a pump enclosure assembly Comprising a canister having a liquid-tight partition therein dividing the interior thereof into a pump compartment and a battery compartment, a canister lid, and gasket means sealably interposed between said canister and said canister lid to establish a liquid-tight closure of said battery compartment;

B. a liquid pumping means comprising an electrically energized prime mover disposed in said pump compartment;

C. conductor means to conduct electrical energy from an electric battery disposed in said battery compartment to said prime mover; and

D. switch means located on the battery compartment side of said enclosure assembly and in circuit with said conductor means.

11. The device of claim 10 wherein said pump compartment has a floor thereacross displaced vertically upwardly from the lower margin of said canister and wherein said pumping means comprises i. an impeller chamber integral with and depending below said floor and having an inlet and a separate outlet to conduct liquid into and out of said impeller chamber;

and ii. an impeller disposed in said impeller chamber and in rotational driven engagement with said prime mover.

12. The device of claim 10 wherein said pumping means is a vertical shaft impeller pump.

13. The device of claim 10 wherein said prime mover is disposed in a liquid-tight casing therefor and wherein said pump compartment comprises means for providing free access of liquid thereinto and comprises a headspace in the upper portion thereof.

14. The device of claim 13 wherein said headspace is vented.
