March 1960 w. D. BEARD ETAL ELEVATED DISCHARGE SUMP PUMP (CELLAR DRAINER) Filed May 9, 1958 INVENTORS yaw/Wm 75W 022m 7 m BY% ATTORNEY ELEVATED DISCHARGE SUMP PUMP (CELLAR DRAINER) William D. Beard and Luther Peters, Washington Boro, Pa.

' 2Claims. c|.-a- -s7')- This invention relates to a portable motor operated sump pump.
The principal object of this invention is to provide a novel portable motor operated sump pump including a vertical standard housing an impeller driving shaft and a fluid passage whereby fluid enters the base through suction and passes upwardly through the standard and is discharged adjacent the upper end thereof.
Another object is the provision of an improved portable motor operated sump pump including a vertical standard having the motor arranged on the upper end and the fluid inlet opening in the base so that fluid passes into the pump at its base and is discharged adjacent its upper or motor end.
Still another object is the provision of a novel portable sump pump which is adapted to be easily positioned in a location to be drained which will permit ready cleaning of such location.
A further object is to provide a novel portable motor operated sump pump which is inexpensively constructed, relatively light, and which is adapted to be readily installed and disconnected.
These and other objects will be apparent by referring to the accompanying drawings, wherein:
Figure 1 is an elevational view, partly in section, of my improved sump pump;
Figure 2 is a bottom plan with the cover plate removed; and
Figure 3 is a section on the line 3-3 of Figure 1.
Referring more particularly to the drawings, wherein like reference characters designate similar parts throughout the several views, numeral 1' indicates a hollow annular sump pump base upon which detachably receives the lower end of centrifugal sump pump casing or standard 2. Within the lower annular base portion 3 of the base is an impeller 4 which is removably threadedly connected, as at 5, to the lower end of a vertical shaft 6 housed within the casing 2. The lower and upper ends of shaft 6 are provided within bearings 7 and 8, and the upper end of this shaft 6 is suitably coupled, as at 9, to the lower end of a shaft 10 depending downwardly from and driven by a conventional electric motor 11 suitably supported on the upper end of the casing 2.
The hollow annular base 1 is provided with an open lower end 12 and a cover plate 13, having a central opening 14, is suitably mounted within the lower end of base 1 spaced above the opening 12 thereof so as to be disposed just below and in close proximity to the underside of impeller 4. A series of inlet openings 15 is formed in the lower rim portion and extends throughout about one half the circumference thereof, as best shown in Figure 3. Openings 15 extend inwardly and downwardly through the rim (see Figure 1) so that fluid will flow inwardly into the base and will be drawn upwardly through cover plate 13, by virtue of suction created by impeller 4. The base 1 is enlarged at its lower end and generally tapers upwardly in size to the point where it 4. An inlet opening 19 is formed in the wall of casing 2 above the upper end of baflle 18, and a threaded outlet or discharge opening 20 extends laterally through the. upper end of casing 2 below upper shaft bearing 8; Therefore, it is apparent that the shaft 6 is ar'rang'ed'iri casing 2 so as to be spaced therefrom to provide a fluid conduit or passage for fluid therethrough.
The sump pump base 1 is positioned in a depression or sump in the floor of a cellar and the like where fluid has accumulated and will be submerged therein in an obvious manner. Thus, when the motor 11 is actuated, the shaft 6 and impeller 4 will be rotated to create a suction in the base 1 which will suck fluid inwardly through inlet openings 15 causing it to flow upwardly through cover plate opening 14 and thence directed upwardly through tapered flow passage 17 from whence it flows into the lower end of easing 2, through inlet opening 19. The fluid thereafter flows upwardly through casing 2 and passes outwardly through outlet opening 20 in the upper end thereof. It will be understood that a hose or other conduit, not shown, may be attached to the threaded outlet 20 whereby fluid may be conducted to a point remote from the pump and discharged. The motor 11is preferably automatically operated so as to cut on and off as conditions warrant through the medium of a conventional float 23 suspended by a chain or the like 22 from a conventional switch 21 mounted on the upper end of casing 2 below the motor. It will be apparent that float 23 will move vertically with the riseand fall of fiuid in the sump and thereby switch the motor 11 on and ofi, in an obvious and conventional manner, to control operation of the pump.
Thus, it will be understood that in operation of the pump, fluid is drawn into the base 1 thereof and is directed upwardly through the hollow casing 2 and thence outwardly through outlet 20 at the upper end thereof. Hence, the pump casing and base houses the pump parts and also acts as a conduit for fluid.
While we have illustrated and described a preferred embodiment of our improved sump pump, it will be understood that various changes and improvements may be made thereinwithout departing from the scope and spirit of the appended claims.
What we claim is: g
1. A sump pump comprising an elongated vertically extending hollow standard, a downwardly and outwardly extending annular base affixed exteriorly to the lower portion of said standard, an electric motor mounted upon the upper end of said standard, an impeller positioned in said base immediately below said standard, an upper bearing affixed in said standard adjacent the upper end thereof, a lower bearing mounted in the lower end of said standard, a shaft extending through said bearings and. interconnecting said motor and said impeller, said standard having an inlet opening immediately above said lower bearing and an outlet opening immediately below said upper bearing, an offset portion formed on one side of said base and providing a tapered fiow passage from said impeller to said inlet opening, said base having a plurality of inlet holes below the bottom of said impeller, and a downwardly flared bafile afiixed to the outer side of said standard below said inlet opening and extending into said offset portion to form one side of said flow passage.
