ROTARY WATER PUMP. APPLICATION FILED SEPT.25. 1919.

UNITED STATES PATENT OFFICE.
MOBIL V. ANDREWS AND STEPHEN W. I-IOLMAN, 0F MARMARTH, NORTH DAKOTA,
ASSIGNORS TO MORA PUMP COMPANY, OF MARMARTH, NORTH DAKOTA, A COR- PORATION.
Application filed September 25, 1919.
To all whom it may concern:
Be it known that we, MOBIL V. AN- nnnws and STEPHEN XV. HOLMAN, citizens of the United States, residing at Marmarth, in the county of Slope and State of North Dakota, have invented certain new and useful Improvements in Rotary ater-Pumps, of which the following is a specification.
This invention relates to rotary vacuum pumps and pertains especially to a rotary water-lifting pump of special design.
The object of the invention is to provide a rotary water-lifting pump embodying a central gear disk having radial vanes cooperating with a pair of cut-ofi rollers geared with and revolved by the disk and having a cut-out for said vanes.
A further object of the invention is to provide a rotary force pump having a pcculiar casing or shell through which water isforced by means of revolving vanes cooperating with cut-ofi" rollers, the vanes and the rollers being contained within the casing and sub-casings respectively and forming a vacuum.
Various other objects, advantages and improved results are attainable in the manufacture and application of the invention, as will be hereinafter fully set forth.
In the accompanying drawings forming part of this application:
Figure 1 1s a cross section illustrating the invention.
Fig. 2 is a vertical section.
Fig. 3 is a detail edge view of the disk gear showing the radiating vanes.
The same reference characters denote the same parts throughout the several views of the drawings.
In carrying out our invention, we have devised a peculiar circular casing in two parts as 1 and 2 having annular meeting flanges 3, which, when bolted together as at 4, constitute a closed periphery and form an annular channel 5 central of the casing, as will be hereinafter more particularly referred to. The casing members 1 and 2 are flared or inclined outwardly from a hub section or casing member 6 for a shaft 7 having a driven pulley 8, and the lower portion of said members is attached to a base or support as 9 by means of legs or brackets 10. The shaft 7 is journaled in a standard 11 projecting from the base, and the shaft may be extended beyond the stench Specification of Letters Patent.

ard bearing 12' so as to have a crank handle applied thereto for operating the pump by hand, and other driving means may be applied to the shaft in lieu of the pulley.
The upper portion of the peripheral flanges 3 is extended laterally in inclined position, and upon opposite sides of the casing members 1 and 2 is formed a sub-casing or housing 13 integral with the said flange extensions, which form a top closure for the sub-casings, while the bottom of the subcasings is closed by a lateral inclined extension 14: of the casing members 1 and 2 adjacent to the hub member 6. The subcasings are provided with closed trunnion bearings 15. These sub-casings or housings overhang the casing-hub 6 at an angle thereto centrally above the shaft 7, and between the water induction port 16 of the casing which has a suitable water induction pipe 17, and the water eduction port 18 having a suitable discharge pipe 19.
An important feature of our invention is the construction of the water suction or conveyer wheel or disk20 and its arrangement relative to and in cooperation with a pair of conical cut-off rollers 21. The disk has a hub 22 and a pair of vanes 23 radiating from the hub 22 to the periphery of the. wheel. The vanes project from opposite faces of the wheel or disk opposite each other and are tapered from the hub 22 to a widened outer end so as to it the shape of the chamber 24; formed by the casing members 1 and 2. The periphery of the wheel 20 has a double beveled gear 25, meshing with a gear 26 on the upper end of the rollers 21, having trunnions 27 working in the bearings 15 which revolubly retain the rollers in the sub-casing 13 at an angle to the wheel 20 so that the rollers project into the path of movement of the vanes. The r0llers have a lengthwise peripheral cut out 28 adapted to permit the vanes to pass the rollers as the wheel 20 is revolved between the rollers. The various journals are provided with suitable oil cups as 29, and the toothed periphery of the wheel 20 works in the casing channel 5.
Obviously the rollers separate the induc tion and eduction ports, the revolution of the disk vanes creates a suction, and said vanes carry the water from one port to the other on both sides of the disk or wheel 20 while the rollers are being revolved by the Wheel so as to place the roller cut outs opposite each other for simultaneous engagement with the vanes. It being understood that the gears are to be so proportioned and the cut outs of such width as to afford said engagement without interfering with the induction and the discharge of the Water during a pumping operation. It will be seen that the ports are located adjacent to and upon each side of the rollers so as to deflect the water into and out of the chamber 24, and that the vanes maintain a division of the said chamber on each side of the gear disk so as to conduct a double body of Water from one port to the other at every revolution of the disk, thereby multiplying the capacity of the pump.
It will be observed that the sub-casings or roller housings are formed in the same piece with the casing members 1 and 2, that When said members are secured together they inclose the disk and the rollers and form a water-tight chamber, and that this arrangement constitutes simple and expeditious means of assembling and disassembling the pump parts.
We do not Wish to be understood as confining ourselves to any particular size or capacity of the pump, to any particular means for driving the pump, nor to any particular material comprising the various parts, neither do we wish to confine ourselves in the use or application of the pump, but reserve the right to make such changes and variations in the manufacture and practical application of the invention as may not be inconsistent with the appended claims.
Having thus described our invention what we claim as new and desire to secure by Letters Patent is:
1. In a rotary pump, a cylindrical casing,
a double gear disk revolubly mounted in the casing, a pair of vanes extending from the hub of the disk to the periphery of the disk opposite each other on each side of the disk, a casing-inclosed roller on each side of and geared with. the disk, said rollers having a cut-out for the passage of the vanes during the revolution of the disk, and means for revolving the disk in a water pumping op eration.
2. I11 a rotary pump, a cylindrical easing, a double gear disk revoluble in the casing, a pair of radial vanes on each side of and at an angle to the faces of the disk, a pair of cut-ofi' rollers having a gear meshing With the disk gear, said rollers being revolved between the casing ports and having cut-outs gorkthe vanes, and means for revolving the 3. A rotary Water pump comprising a rotary disk having peripheral side teeth, a pair of vanes on each side of the disk and diverging outwardly from the axis to the periphery of the disk, a cutoff roller on each side of the disk and having teeth meshing with the disk teeth, said rollers being conical and having lengthwise cut-outs for the vanes and permitting the disk to be revolved therebetween, a casing inclosing the disk, sub-casings inclosing the rollers at an angle to the disk, a water induction pipe and a water eduction pipe connected with the casing respectively on opposite sides of the rollers, and means for revolving the disk.
In Witness whereof We hereunto set our hands in the presence of two Witnesses.
