Application filed .Tune 6, 1910. Serial No. 565,227,
To all whom it may concern Be it known that I, IRA Born HU rnRnYs, a citizen of the United States, residing at Denver, in the county ofDenver and Stateof Colorado, have mvented certa n new anduseful Improvements inRotary Pumps, of which the following is a specificationl My invention relates to an improvement in rotary pumps, and the object is to provide a rotary abutment or runner which is provided with gears which are adapted to rotate in the opposite direction to the rotation of the abutment, for. causing water to be pumped up through the casing and dis charged at the upper end thereof.
A further object is in providing an abutment which has a suction and discharge chamber on each side thereof.
The invention consists in certain novel features of construction andcombinations of parts which will be hereinafter fully clescribed and pointed out in the claims.
In the accompanying draWingsP-Figure 1 is a vertical sectional view; Fig. 2 is a crosssectional view; and Fig. 3 is a view in. perspective of the abutment, partly broken away to disclose one of the discharge chambers. 1
A represents the annularfgear casing, and B and C are the heads between which the casing is mounted. The heads are provided with hubs '1 which are supported within the heads by ribs or spokes 2. A runner or abutment D is mounted in the casing A and is provided at each end with shafts 3, 3, which are received in the hubs 1 of the heads B and O. The sides of the abutment are made concave, as indicated at 4, and journaled between the top 5-and bottom 6 of the abutment and on each side of the central web 7, are spur gears 8 and 9. The gears are adapted to mesh with the teeth 10 of the annular casing, and travel through the curved or concave portion of the abutment which is formed on each side of the web 7 Formed between each end of the abutment and web 7 and atdiagonally opposite points, are discharge chambers or conduits 11 and 12, which extend in a diagonal direction from the bottom 6 through the top 5 of the abutment. Openings 13 and 14 are formed through the bottom 6, whereby the water is sucked or drawn into the suction chamber formed between 5 the web 7 and casing A.
The rotation of the abutment causes the spur gears 8 and 9 to rotate in an opposite direction, The rotation of the spur gears causes the water to be drawn into the suction chamber, and as the spur gears travel,
' the water will be carried between the teeth,
around the curved or concave surface of the web 7, and discharged into the dis charge chambers 11 and 12, the spur gear 8 discharging the water into the discharge chamber 11 and the spur gear 9 discharging the water into the discharge chamber 12, through which the water is conducted to V the top of the abutment, from whichit is conducted through the top of the casing. The spaces between the teeth are filling with water from the water drawn through the openings in the bottom of the abutment as the abutment turns, and as the abutment continues to rotate these spaces, being full of wateigare brought past the curved surfaces of the abutment, and discharge the water into the discharge chambers, and the close meshing of the teeth of the gears forces the water up through the discharge chambers or conduits through the head B. In each revolution of the abutment, each spur gear carries as many teeth full of wa ter as there are teeth in the annular gear; the annular gear having two gears meshing with it, and two abutting surfaces, carries twice as many teeth full of water as there are teeth in the gear, each tooth working twice in each revolution. Therefore, in each revolution of the abutment, there are four times as many teeth full of water pumped as there are teeth in the annular gear.
what I claimas new and desire to secure by Letters Patent, is
1.111 a rotary pump, the combination with a stationary gear casing, having heads connected at the ends thereof, said heads havin openings formed therein, hubs supported within the heads, of a runner rotatably' mounted in said hubs and supported thereby, said runner having the sides thereof made concave, spur gears journaled between the ends of the runner and received in the concaved sides, the teeth of the spur gears meshing with the teeth of the gear casing, said gears adapted to be rotated upon the rotation of the runner, due to their engagement with the casing, whereby the Having fully described my invention,
gears will cause a constant suction of water into the casing and discharge the water continuously through the casing.
2. In a rotary pump, the combination with a stationary casing, having gear teeth thereon, of heads connected to the casing having open ends, of hubs supported in the heads, a runner j ournaled and supported in the hubs and provided with suction and discharge openings in the ends thereof, spur gears journaled between the ends of the abutment, having teeth which are adapted to mesh with the teeth of the casing, whereby, upon the rotation of the abutment the spur gears will be revolved, causin the wa- 5 ter to be sucked through one of the heads and through the abutment, and discharged through the opposite end of the abutment and through the casing. r i
In testimony whereof I afiixmy' signa 20 ture, in the presence of two witnesses.
