' Specification of Letters Patent. I
Patented May 27, 1913.
estimati n filed April 12, 1912. Serial No. swash I EISSUED.
To all whomoz't may concern:
Be it known that I, WALTER AIKEN SI- MOND, a citizen of the United States, and a resident of Franklin, in the county of Merrimack and State of New Hampshire, have invented a new and Improved Rotary Pump, of which the following is a full, clear, and exact description.
This invention or centrifugal pumps for water or other fluids, and such as are adapted for use on shafts which are vertical or inclined to any extent.
The invention consists of the peculiar features of construction hereinafter fully described and claimed and illustrated in the accompanying drawings, in which Figure 1 is a vertical section substantially on the line 11 of Fig. 2; Fig. 2 is a plan view with the upper face plate removed; and Fig. 3 is a detail of an alternative means for connecting the face plate or cover to the main body of the casing.
The pump herein set forth comprises a casing 10 adapted to be introduced into or to be located in any place from which water or other fluid is to be pumped, as for instance a well, hold of a vessel or the like, indicated conventionally at 11.
At 12 is indicated a driving shaft, shown as being arranged vertically and stepped into a base 13. While said shaft is described as being vertical, it will be understood that it may be arranged in any other position and the other portions of this description will be read and interpreted accordingly.
The principal movable part of this pump consists of a rotor 14; comprising a simple disk 15 adapted to be driven at high speed by the shaft 12, but with which it has preferably loose longitudinal connection. Such connection is herein indicated as being made by the key16 extending from the shaft into a keyway 17 in the disk. The rotor disk has rigidly connected or formed integrally therewith a pair of equal oppositely arranged volutes or spirals 18 and 19, said spirals being on opposite sides of the disk and so arranged that one of them is 180 degrees in advance of the other and in consequence every similar point is diametrically opposite, whereby the device is better balanced with respect to rotation and the efliciency of the pump materially increased. In fact, I have found, by extended experiments, that has reference to rotary,
adjacent the spiral 18. These openings may permit fluid of the same kind to be admitted into the casing, or by suitable arrangement of pipes, fluids of different species may be introduced into the pump from opposite sides to be therein mixed and delivered from the casing through the outlet 23.
The shaft 12 is provided with a collar 24 which support-s the rotor under certain conditions, but the form and arrangement of the casing and rotor are such that when driven at the ordinary high speed, the rotor will be self-centering or will be floated in the casing independently of said collar. The cover 21 may be secured to the casing either by a set of screw bolts 25 as indicated in Fig. 1, or by means of screw threads 25 as shown in Fig. 3, and subsequently locked in place by one or more set screws 26. When this pump is used for conveying sandy or gritty fluids, I may provide one or more wearplates 27 within the casing and carried preferably by the spirals 18 and 19.
I desire not to be limited to the exact features of construction herein illustrated; for instance, the spirals may have more or less convolutions, depending upon the work to be performed. If the load is heavy, as for instance during a high lift, the number may be materially increased, whereas if the lift is low, the spirals may have a lesser number of turns. Again, it is to be noted that the outer end of each spiral is so formed as to be approximately concentric with the shaft whereby the resistance to high rotation is decreased, although I prefer to form the channel of the spiral of approximately uniform cross section.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: r
In a centrifugal pump, a rotor consisting of a simple disk having on each side thereof a single spiral channel, the channel on one side of the disk being approximately 180 in advanceof the channel on the other side,
and the said channels being non-alined throughout their length, a shaft on which In testimony whereof I have signed my the disk is mounted and by which it Is adaptname to this specification in the presence of 10 ed to be rotated, and a caslng lnclosing the two subscribing witnesses.
said disk and provided with bearin s in T which the shaft is rotatable, and havin g op- WALTER AIKEN SIMOA poslte central openings for the admission Witnesses:
of fluid, and a' peripheral opening for the EDWARD G. LEAoH,
discharge of fluid. HoLLIs K; SMITH.
Copies of this patent may be obtained for five cents each, by addressing the Commissioner of l'atenta, Washington. D. C."
