Abstract
A portable bailer is used to remove fluid such as water from a watercraft, such as an open-topped powerboat or rowboat. The bailer features an electrically actuated fluid pump contained within a one-piece protective external molded housing also containing a suitable battery such as a suitable rechargeable battery in close proximity to the fluid pump and operative to provide power to the fluid pump upon actuation. The fluid pump and battery are located intermediate an elongated input section and an elongated output section of respective indeterminate lengths. A portion in close proximity to the distal end of the output section is formed into an inverted J-like configuration operative to direct the pumped fluid outwardly over the gunnel of the watercraft.
Description
PORTABLE BAILER
FIELD OF THE INVENTION
The present invention is directed generally to a portable bailer. More particularly, the present invention is directed to a portable bailer used to remove fluid such as water from watercraft such as an open-topped powerboat or rowboat. More specifically, the present invention is directed to a portable bailer including an electrically-operated fluid pump in close proximity to a power source such as a battery pack. The pump and battery pack are enclosed within a one-piece protective external molded housing intermediate elongated input section and an elongated output section of respective indeterminate lengths, with a portion in close proximity to a distal end of the output section formed into an inverted J-like configuration operative to direct the fluid over the gunnel of the watercraft. The pump is actuated by a manual switch preferably mounted on an external handle secured to or integral with an external surface of the molded housing.
DESCRIPTION OF THE PRIOR ART
Various electrically-operated pump assemblies have been proposed in the past for use in the removal of fluids such as water from watercraft. The majority of these, however, are intended for use in applications in which weight, compactness, and simplicity of operation are not primary factors. These prior art devices typically utilize float switches that may be permanently secured to the floor of the vessel, or may float on the surface of the water in the vessel. None of these prior art devices are suitable for use in watercraft such as an open-topped powerboat or rowboat where ease of operation, durability, portability, light-weight, and speed of removal of fluid from the watercraft is essential. One example of prior art can be found in United States Patent 5,669,323 in which an automatic bailer is disclosed for removing water from a white water canoe. This bailer, however, differs from the bailer of the present invention by utilizing a float-actuated pump and not having a battery and pump in close proximity located within a single, external molded housing located intermediate elongated inputand output sections of respective indeterminate lengths, as associated with the portable bailer of the present invention. The prior art bailer also utilizes a 12-volt battery located outside the housing surrounding the pump rendering the combination extremely heavy and difficult to move. Also another prior art publication is Canadian application CA 2484798 for a cordless dockside boat bailer which differs from the proposed bailer. It differs by having a bilge pump located at the distal end of the input section and having an output section intermediate the battery and the pump and also having external electrical wiring between the battery and the pump highly subject to damage. Also of interest, the following United States patents are listed for general information: 5,493,982; 5,257,590; and 5,211,363. Also of interest are the following Canadian patents: CA 542062; CA 667804; CA 519585; and CA
445313.

Yet a further object of the present invention is to provide a portable bailer in which the external housing is disposed intermediate elongated input and output sections of indeterminate length extending therefrom. An additional object of the present invention is to utilize a portable bailer which is light-weight, easy-to-handle, and less subject to damage by having the pump and battery contained in close proximity to each other within a protective one-piece molded housing.
The portable bailer, in accordance with the present invention, includes an electrically-operated fluid pump that is connected to a power source such as a battery pack. (preferably a ....a............_._~....,_.____..._..... _. ...... . . . CA 02586935 2007-05-rechargeable battery pack). The portable bailer, in accordance with the present invention.
preferably includes a one-piece molded external housing surrounding the pump and battery that are in close proximity to each other and are disposed intermediate input and output sections extending therefrom of respective indeterminate lengths and having passageways therethrough that are respectively in fluid communication with the fluid pump.
The portable bailer of the present invention is preferably manually-operated.
through provision of an electrical switch preferably located upon an external handle either secured to or integral with an outer surface of the molded external housing. The switch is preferably a slide or a push button-type switch but way also be a toggle, or a rocker-type switch, or another suitable switch.

Section 3 has a fluid passageway 21 therethrough in fluid communication with the fluid pump. Bailer 30 also has an input or inlet Section 4 having an indeterminate length Ly and having a distal end 10. Inlet Section 4 has a fluid passageway 22 therethrough in fluid communication with the fluid pump. Although shown in the Figures as having a substantially tubular cross-sectional configuration, inlet Section 4 and/or outlet Section 3 may have any cross- sectional configuration provided that the bailer of the invention operates in the manner desired. Bailer 30 is also provided with a handle 5, operative to enable a person to hold the bailer of the invention by hand and is either secured to or molded integrally with the protective molded housing enclosing the fluid pump and the battery. Bailer 30 of Fig. 1 is also provided with an electrical switch member 6 that is preferably mounted on handle 5 for ease of operation. Handle 5 may also be mounted upon an external surface of the molded housing wherever suitable for actuation. Although switch 6 is preferably a slide or push-button type switch, it may be any type of electric switch deemed suitable for the actuation of the fluid pump such as a rocker-arm or toggle type switch provided it is operable to actuate the fluid pump upon actuation of the switch. Bailer 30 is also provided with a battery compartment access door 8.
Although shown in Fig.'s 1- 4, 8, and 10 as located on the front side of the bailer of the invention, the battery compartment access door may be located at any suitable location on the outer surface of the molded housing such as, for example shown on the backside of Section 2 facing away from handle 5 in Fig.'s 6 and 9.
