WATER PUMP.
Application filed October29, 1924. Serial No. 746,601.
minals of novel design to lift and expel the water with minimum resistance and in a constant stream the volume of which is predeterminedby the speed of the motive means employed.
A coordinate object of the invention is to provide a very simple yet durable type of pump which although especially adapted for use 1n elevating water may manifestly be used in various other capacities.
Further objects of the invention will be apparent from thefollowing description of .the present preferred form of the invention taken in connection with the accompanying drawings wherein Fig. 1 is a side elevational view of a pump constructed in accordance with the present invention, the inlet and outlet pipes of which are shown fragmentarily;
80 Fig. 2 is a longitudinal sectional view of the pump;
Fig. 3 is an end elevational view of the outlet casing looking at the inner end of the latter;
Fig. 4 is a similar view of the inlet casing; Fig. 5 is an end elevational view of the piston; and
Fig. 6 is an end elevationalview of a modified form of inlet casing looking at the 4.0 inner end of the latter.
The pump constructed in accordance with the present invention consists especially of a cylinder 7 made of any desired metal and of any size for particular adaptation to the 4 work to be performed. The cylinder is adapted to receive apiston 8 which in the present instance is shown to be of spiral configuration being made up of four blades the outer margin of each of which hasone side 9 flared outwardly. The bore of the piston is adapted to receive a drive shaft 10 therethrough the ends of which extend appre- -ciably beyond the ends of the cylinder 7 of the pump. The pitch of the blades as well as the relative positioning of the same is determined by the load to be taken care of.
However, the pitch of the blades and the.
proximity of positioning the same, together with the particular configuration of the margins thereof, as shown in the drawings, is a preferred form for practical functioning of the piston.
Mounted one end ofthe cylinder 7 an inlet casing 10 and in the opposite end an outlet casing 11. The inlet casing 10 is provided with a central bore through which one terminal of the power shaft 10 extends, the; diameter of the bore being in excess of the diameter of the power shaft soasto accommodate a bearlng sleeve 12. The casing 10 is also provided witha-latera-l opening into I which one end of an inlet pipe 13 fits, the.
opposite end of said pipe leading to the source of supply. The inlet pipe 13 communicates with one terminal of a spiral way 14 which is formed in the casing 10, the opposite end of said way extending through the inner end of the casing 10 so as to communicate with the cylinder 7. T he inner end ofthe casing 10 slidably fits in thecylinder 7 inward movement thereof being limited by an annulus 15 which is formed on the outerperiphery of the casing 10. The casing 10 is anchored on the bearing sleeve 12 by a bolt 16 and the casing is also secured to the cylinder 7 by means of bolts 17. As shown in Figs. 2 and 4, the wall which defines the path of the spiral way 14 in the inlet casing has its inception at the base of the inlet pipe 13 and terminates at the extreme inner end of the casing and lies flush with said inner end. This construction is preferable where the load to be lifted is heavy. Where the load is light the spiral wall maybe eliminated thereby leaving only an annular depression 18 in the inlet casing, as shown in Fig. 6.
The outlet casing 11 is mounted in the cylinder 7 in the same manner as the inlet casing 10 and is provided with a spiral waterway 20 the inner end of which communicates with the cylinder and the outer end of which comn'iunicates with alateral opening formed in the casing, said opening receiving one end of a discharge pipe21. The opposite end of the discharge pipe may be extended to any point where the water is to be dispensed. The casing 11 is mounted on the power shaft 10 in the same manner as casing 10 and is somewhat. from the inner face of the inlet asing by forming a portion of the outer end of the spiral wall flush with the inner end of the casing to provide a segment 22 from which the spiral Wall slopes toward the outlet pipe 521,. However, it. desired. the outlet casing may be of the same design as the inlet; caslng.
One end of the power shaft 10' extends beyond the inlet casing 10 and is mounted for rotation in a bearing plate 23 which latter is bolted to the casing 10. The opposite end of the power shatt projects to any desired distance beyond the outlet casing 11 and is adapted for operative connection with a motor or similar power element which will rotate the shaft 10. Since the shaft is keyed to the piston 8, as indicated at 24. the piston will rotate as a. unit with the shaft. If desired the piston and shaft may be integrally formed with the same result.
Detachably mounted in the cylinder 7 is an air valve 25 through which air in the cylinder may be expelled.
In use of this device rotation of the power shaft 10' will correspondingly rotate the piston 8 so as to create a vacuum in the cylinder 7 thereby siphoning the water through the inlet. casing 10 and into the cylinder. lVhen the water reaches the cylinder it is carried by the .blades of the piston to the discharge casing and there expelled through the pipe 21. By tapering the ways 14 and 20 of the inlet and outlet casings, respectively. of the pump, the water is first introduced into the cylinder in a spiral path and in view of the symmetrical formation of the piston, the water is pumped with minimum It'rlfittlllt't: through the cylinder and outlet casing. By so mounting the inlet and outlet casings in the cylinder that portions of the casings projeet into the latter, not only is possibility of leakage of the pump reduced to a minimum but furthermore the spiral ways of the casing are brought into such close proximity to the piston that the onus of elevating the water is reduced to a minimum. Moreover. the blades of the piston are so arranged as to clear the wall of the cylinder and also of the casings 10 and 11 so that. frictional resistance in this respect is likewise eliminated.
It is of course understood that the device of the present invention is aday'ited for use in various capacities and that the pump is susceptible to change to conform to the character of work lmdertaken. llowever. the form of invention illustrated herein shows a practical embodiment of the device and numerous changes may be made therein within the scope of the claim hereto appended.
\Vhat is claimed is:-
A pump including a cylinder equipped with terminal casings having spiral ways therethrough. and a piston rotatably mounted in said cylinder including spirally wound blades the leading edges of which are flared outwardly in the direction of movement of the piston.
In testimony whereof I altix mv seal.
