Specification of Letters Patent. yg
Application filed July 1'0, 1909. Serial No. 506,909.
To all 'whom Iit may concern:
Be it known that I, IRAA Born HUM- PHREYS, a citizenof the Unitedb States, residing at Denver, in the .county of Denver 'and State ofhColorado, have invented vcertain new andvu'seful Improvements in Rotary Pumps, of which the following is a specification.
My invention relates to an ,improvement in rotary pumps, and the object is to rotate -the abutment or runner and the spur gear, whereby the outer casing is not rotated and the vwater is drawn into the casing by the suction action of the rotating parts and carried from the suction chamber between the abutment and the spur gear into the outlet chamber where the water is dis- Vcharged through the top of the pump.
" The invention consists of certain novel features of construction yland combinations of arts, which will. be hereinafter described and pointed out in the claims.
In the accompanying drawings: Figure 1 is a vertical sectional view; Fig. 2 is a cross section, and Fig. 3 is a top plan view of the abutment or runner. J
A represents the annular gear 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 2, 2. Connected to the head B is an outletpipe 3, which is provided with a stuifin'g box 4. .A shaft 5 is journaled in'the hubs 1 and in the stufling box 4. An abutment or runner D is mounted in the casing and is provided with an annular ring 6 at the top and a similar: annular ring 7 formed at the bottom thereof, which rings are partially closed forming an outlet opening 8 in the ring 6 and an inlet opening 9 in the ring 7 A curvedplate 10 connects the tworings together and a 'curved plate 11 is`connected to the body or central portion of each ring. A vw'eb 12 connects the curved j late 10 and the curved plate 11 thereby dividing the body of the casinginto two chambers.l A spur ear 13 is mounted on vthe stud shaft 14, w ichflis mounted onthe body'of the ring 7. The spur gear extends up to the body of the ring 6. The vertical inginto suction and outlet or discharge chambers.
' discharge pipe 3.
The teeth of the spur gear 13 will mesh with the teeth'of the annular casing A, and as the shaft 5 is connected to the body or central portion of the rings 6 and 7 the runner or .abutment Will be rota'ted upon the rotation of the shaft 5. The pump or casing being submerged in water the rotation of the abutment or runner will create a suction drawing the water into the suc- Patented Sept 6, 1910.
tion chamber through the opening 9 in the base lof the runner. ner will cause the spur gear to. rotate, which will rotate in an opposite direction to the rotation of the runner, caused by the engagement of the teeth of the spur gear .with the teeth of the (rear casing. The water in the suction cham'loer will be transmitted to the outlet chamber., by traveling through' the meshes of the spur gear and the curved plate 11. it will be discharged through the outlet opening 8 `and through the head B into the Having fully described my invention, what I claim as'new and desire to secure by Letters Patent, is
1. In a rotary pump, the combination with a casing having gear teeth thereon, of an abutment mounted in the casing, a. spur gear mounted on the abutment the teeth of which are adapted to mesh with the teeth on the casing, said abutment and spur `gear dividing the casing into a suction -and a discharge chamber, means for operating the abutment, whereby the'water is drawn into thesuction chamber and Vtransmitted from the suction chamber to the discharge chamber from which it is discharged.
2. In a rotary pump, the combination with a casing having gear teeth thereon, of an' lspur gear mounted on the lower member,
the teeth of the spur gear meshing withthe teeth on the casing, and means for operating thefabutment.
In testimony whereof I afiix my. signature, in the'presence of two witnesses,
