Description
Dec. 31, 1963 l r Ill L. H. DODGE PUMP . Filed May 7, 1962 1N VEN TOR Patented Dec. 31, 1963 ice 3,115,842 PUMP Lucius H. Dodge, Box 325, Cape Vincent, N.Y. Filed May 7, 1962, Ser. No. 192,797 1 Claim. (Cl. 10389) This invention relates to improvements in pumps and more particularly to power operated impeller-type pumps.
It is an object of the present invention to provide a power operated pump that will substantially deliver liquids under pressure while substantially reducing the sediment content passing through the outlet thereof.
Another object of the present invention is to provide a pump that is substantially self-lubricated by the fluids passing therethrough.
Gther objects of the invention are to provide a pump bearing the above objects in mind which is of simple constructions, has a minimum number of parts, is inexpensive to manufacture and efficient in operation.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in conjunction with the accompanying drawing, in which:
FIGURE 1 is a vertical view comprising the present invention;
FIGURE 2 is a transverse view taken on the lines 22 of FIGURE 1;
Referring now more in detail to the drawing, a pump made in accordance with the present invention is shown to include an elongated and circular sleeve 12 have a larger diameter base 14 with a projection 16 centrally thereof providing bearing means for the actuated component within. A circular opening 18 thrugh the upper externally threaded end of sleeve 12 provide outlet means for the fiuids through opening 20 of pipe projection 22 which projects from the cap 24 which is internally threaded receiving the externally threaded upper end of sleeve 12. The stuffing box 26 extends upwardly and centrally from cap 24 and freely and rotatably receives an elongated and circular shaft 28 which extends downwardly through a spider 30 at the upper end of sleeve 12 and the spider 32 at the lower end of sleeve 12 above the base 14. A propellor 36 is fixedly secured to shaft 28 below the spider 32 there within sleeve 12 having a pitch suitable for the pressure desired within the pump 10. The lower-most end of shaft 28 extends downwardly into the base 14 into the projection 16 and is lubricated by the fluid transported through the sleeve 12 and an inlet pipe 37 projects upwardly therefrom the base 14 providing an inlet means for fluids to be received within the sleeve 12. Power means is supplied to shaft 28 by external motor 38 projecting above cap 24.
In operation, the worker switches the motor 38 on and shaft 28 rotates thus rotating the propellor 36 which causes a differential in pressure within sleeve 12 and the propeller 36 draws the fluid through pipe 37 and through sleeve 12 and through the outlet-type 22 and the sediment contained in the fluids incoming through base 14 is urged towards the outer perifery 0f the base 14 by centrifugal force which is created by the propellor 36.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
What I claim as new and desire to protect by Letters Patent of the United States is:
A pump adapted to be operated by an electric motor, comprising a vertical tubular member, one end of said member immersed in the liquid which is to be pumped, discharge means in said member at the other end thereof, a drive shaft axially disposed in said member and extending longitudinally therewithin, a propeller element carried by said drive shaft in the vicinity of the end of said member which is to be immersed in the liquid, said member in the vicinity of said propeller element having a section adjacent and below the propeller element having a diameter greater than the remainder of the tubular member, said enlarged section being completely closed at its lowermost end and being joined to said member to close the open end of said member and to form an enclosed chamber, and a riser pipe leading into said chamber from the outside and extending upwardly from the top of said chamber to form an inlet to permit the entry into the chamber of fluid and to prevent the entry into the chamber of bottom sediments contained in the fluid to be pumped.
