Description
M. E. DAVIS FOUNTAIN PUMP June 20, 1939.
Filed Dec. 51, 1957 Elmo/WWO M. E. De v56 Patented June 20, 1939 .UNITEDYSTATES PATENT- OFFICE 2,163,194 FOUNTAIN PUMP Marshal E. Davis, Bloomfield, Ind. 7 Application December 31, 1937, Serial No. 182,903 1 Claim. (01. 103-87) This invention relates to'a fountain and it is one object of the invention to provide a device of this character wherein a motor and apropeller are so associated with each other that the entire motor and the water propelling pump may be submerged without damage to the electric motor or only partially submerged in the water which is to be forced upwardly through discharge tubes when the pump is in-operation;
Another object of the invention is to so construct the pump and its motor that the base may serve as a casing for the water propelling blades and the discharge tube through which water passes may assist in supporting the motor casing which is disposed about a column rising from the base.
Another object of the invention is to provide a fountain pump of such construction that water will be discharged in a continuous stream and thus provide an attractive looking fountain when the pump is in operation.
The invention is illustrated in the accompanying drawing, wherein Figure 1 is a sectional view taken vertically through the improved fountain pump, and
Figure 2 is a sectional view taken along the line 2-2 of Figure 1.
The base I of this fountain or fountain pump as it may be called is formed of metal or any other suitable material and is provided with a bottom 2 having a marginal flange 3 which is welded or otherwise secured against the inner surface of the depending marginal flange or Wall 4 of the base. The bottom 2 is spaced from the top of the base, as shown in Figure 1, thereby providing a hollow base defining a chamber 5 having an inlet opening 6 formed centrally of the bottom 2. A hollow tubular column or standard I extends upwardly from the base centrally thereof, and at its upper and lower ends is closed by plugs or blocks 8 and 9 which form tight closures for the ends of the column and prevent water from entering the same. A cross strip II] which extends diametrically through the upper portion of the column serves as a support for the upper plug.
A motor casing II fits about the column or standard 'I with its upper and lower heads I2 and. I3 fitting snugly about the column and welded or otherwise firmly secured thereto. It will thus be seen that the motor casing will be firmly held in place about the column and leakage between the column and the openings in the heads I2 and I3 through which the column passes will be prevented. There have also been provided discharge pipes I4 which extend upwardly from the base at an incline in converging relation to the column, as shown in Figure 1, and then vertically through the motor casing with their ends protruding from the upper head I2. Openings are formed in the upper and lower heads for passage of the discharge pipe and tight joints are formed about the openings through which they pass by welding or soldering in order to prevent leakage. It will thus be seen that water in the base or chamber 5. may be forced upwardly through the discharge pipes I4 and create afountain as it is discharged from these pipes. The pipes I4 may extend upwardly above the motor casing as far as desired. While two pipes I4 have been shown, it will be obvious that any number desired may be provided. x
In order to draw water into the chamber through the inlet opening 6 and discharge this water through the pipes I4, there has been provided a propeller I5 having its hub secured to the lower end of a shaft I6 by a pin l1 and its blades extending radially of the shaft. The shaft I6 extends through the column or standard I axially thereof and the propeller is mounted in the chamber 5 concentric to this chamber and its inlet opening 6. Since this propeller is of appreciably greater diameter than the opening 6 and its blades project beyond the margin of the opening with their free ends terminating close to the lower ends of the pipes I4, water will be drawn into the chamber 5 when the shaft and the propeller are rotated and this water will be forced towards the periphery of the chamber by centrifugal force and out through the pipes I4. The upper and lower portions of the shaft are journaled through the plugs or closures 8 and 9 and passage of water through the plugs about the portions of the shaft journaled therethrough may be prevented in any desired manner.
Within the column the shaft I6 carries a core I8 forming a part of an electric motor, and upon referring to Figure 1, it will be seen that this core is located intermediate the depth of the casing II and spaced equal distances from the upper and lower ends of the casing. A field I9 of a conventional construction and also forming part of an electric motor is mounted in the motor casing about the core and the discharge pipe, and there have also been provided field coils of a conventionalconstruction used in electric motors, these field coils being wound about the column I and extending between the column and the pipes I4. The power wires 2I extend outwardly through a tube 22 which extends upwardly at an outward incline from the upper head l2, the tube being firmly secured to the head l2 and soldering or welding being resorted to in order to prevent leakage of water about the tube and into the motor casing.
When this fountain pump is in use, it is set in place with its baseresting upon the bottom of the bowl or basin of the fountain. It may only have its base submerged in water or the entire motor casing may be submerged as all joints are soldered or welded to prevent leakage and, therefore; water cannot enter the motor casing and cause a short circuit or other damage to the motor. When the current is turned on, the shaft I 6 which constitutes the motor shaft is rapidly rotated and the propeller turned with it. Rotation of the propeller causes a suction which draws water into thechamber 5 through the inlet opening 6 and this water is moved towards the periphery of the chamber by the blades and drivenout of the chamber 5 and upwardly through the pipes I4. The pipes may be open at their upper ends so that columns of water will be discharged to form a fountain or spray nozzles may be provided. The pipes may terminate close to the top of the motor casing or they may extend upwardly as far as desired. When the current is shut oif, the motor ceases to function and the shaft I6 comes to a stop. Discharge of water will then cease but the level of water within the chamber 5 and the pipes I4 will be maintained even with the level of the water in the bowl or basin of the fountain and assoon as the current is again turned on water will bedischarged from the pipes.
Having thus described the invention, what is claimed as new is:
A fountain pump comprising a hollow base defining a water chamber and having a top wall and a bottom, the bottom being formed with an inlet located centrally thereof, a tubular standard rising from the top wall of the base about an opening formed therein over the inlet, a motor casing rigidly mounted about said standard and spaced upwardly from the base, discharge pipes extending upwardly from the top wall of the base about outlet openings therein I and vertically through the motor casing, sealed joints being provided about the discharge pipes at the top and bottom of the casing to prevent leakage and firmly secure the casing to the discharge pipes whereby the pipes act as braces and supports for the casing, plugs closing upper and lower ends of said standard, a motor shaft extending'vertically through the standard and journaled through said plugs with its lower end extending into said chamber, a propeller fixed to the lower end of said shaft within said water chamber and having blades extending radially of the chamber between marginal edges of the inlet opening and the discharge pipes whereby water will be drawn into the chamber and discharged through the discharge pipes when the shaft and the propeller are in motion, a rotor for an electric motor rigid- 1y carried by said shaft within said standard and located intermediate the depth of the motor casing, a motor field in the motor casing surrounding the standard and the discharge pipes, and field coils in the casing disposed about the tubular standard and surrounded by the field.
