Hand-held pumping device

Abstract

A cordless battery powered, hand-held pump, for pumping out liquid, primarily bilge water from small boats, has a support shaft with a submersible pump/motor secured at one end of the shaft, and a handle at the other end of the shaft that is inclined at an angle from the shaft; the pump's liquid discharge connects with an outlet located near the handle, which is aligned with the handle and can connect with a garden hose; a removable, rechargeable battery pack is mounted in the end of the handle, and connects through a lockable switch to the motor. The pump can discharge 10 gallons a minute directly overboard.

1 . An electrically powered, light-weight hand-held pump, for pumping liquid from one location to another, said pump having a support shaft; a combined pump/motor secured to the distal end of said shaft, a handle inclined from said shaft and located at the proximal end of the shaft; liquid discharge means connected with said pump/motor, in use to receive liquid output therefrom, said liquid discharge means having an outlet located between said distal and said proximal ends; battery means to power said motor, and switch means mounted on said handle in controlling relation with said motor means, said handle being in orientation-controlling relation with said support shaft, in use to control the direction of liquid discharge by said liquid discharge means.  
   
   
       2 . The pump as set forth in  claim 1 , said pump having an inlet, the polar axis thereof being substantially parallel with the polar axis of said shaft.  
   
   
       3 . The pump as set forth in  claim 2 , said polar axis of said pump being in substantial alignment with the polar axis of said shaft.  
   
   
       4 . The pump as set forth in  claim 2 , said polar axis of said pump being substantially coplanar with said handle.  
   
   
       5 . The pump as set forth in  claim 1 , said liquid discharge means being located primarily within said supporting shaft.  
   
   
       6 . The pump as set forth in  claim 1 , said battery means being removable and rechargeable.  
   
   
       7 . The pump as set forth in  claim 6 , said battery means being located within said handle in off-set relation from the polar axis of said shaft, in use to provide a counterweight to the mass of said pump/motor, to facilitate the accurate positioning of said pump/motor in a desired location.  
   
   
       8 . The pump as set forth in  claim 1 , including filter means to filter liquid passing into said pump.  
   
   
       9 . An electrically powered, light-weight hand-held pumping device, for pumping liquid from one location to another, said pumping device having a support shaft; a combined pump/motor secured to one end of said shaft, a handle located at the other end of the shaft; liquid discharge means connected with said pump/motor, in use to receive liquid output therefrom, said liquid discharge means having a directionally controllable outlet; battery means mounted on said device to power said motor, and switch means mounted on said handle in controlling relation with said motor means, said handle being in position-controlling relation with said pump/motor, in use to control the location of said pump/motor in relation to said liquid.  
   
   
       10 . The pump as set forth in  claim 9 , said battery means being located within said handle in off-set relation from the polar axis of said shaft, in use to provide a counterweight to the mass of said pump/motor, to facilitate the accurate positioning of said pump/motor in a desired location.
