ROTARY PUMP.
Application mea' september To alli/whom it may concern:
Be it known that I, EMoRY CRoUsn, a citi- Wichita, county of Sedgwick, and State of Kansas, have-,invented certain new andv useful Improvements in Rotary Pumps; and I do declare the followin to be a full, clear,
and exact description o ,the invention, such as will enable othersskilled in the art to 'quantities of liquid. It is also my object together with other vto produce a pump of'large capacity compared to its size and therefore specially adapted to be employed in places where the space is limited.
In order. to' more clearly descnibe my invention L shall refer to the .accompanying drawing in which- Fig. 1 is a side elevation of my pump fully assembled. 1
Fig. 2 is a section on line 2-2 Fig. 3. Fig. 3 is a section on line 3-3 Fig. 1 and Fig. 4 is a longitudinal section taken on line 4-4 Fig. 3. t
The `same reference characters will be used to indicate the same parts throughout the several views. f
i My improved rotary pump comprises an annular body portion 1, a rear side portion or plate2, a. front side portion or plate 3, a rotor 4 and a'plurality of movable plates,
parts which will be hereinafter pointed out. f f v,
Annular body portion 1 has an intake port 7 which `is provided with an extension 8 of considerable length and diametrically opposite port 7 is an exhaust p'ort9 which is also provided with an'extension 10, extensions 8 and 1() being separated by an -arcuate p'ortion 11 which is'adapted to makea water tight sliding fit with the outer surface of rotor 4, in the mannerindicated 'in Fi s.y 2
'and 4. The rear side or .plate 2 is provlded lwith an outwardly projectinghollw'portion 12: which :serves as a bearing for thejrotor 22, 1921. Serial N0. 502,323.
' and 4 they will move the rings 24 against vthe tension of springs 28 and in this manner 'their outer Vedges are held in close Contact side plate 2 may be made integral. Pipes 33 and 34 can be connected respectively with the intake and the' exhaust ports 7 and 9.
turning the rotor 4 but it is obvious that I may operate the pump by other power if I so desire.
The operation ofiny pump is as follows Handle 35 is rotated in a clockwise direc-j N, tion and through the medium ot shaft 13 `rotates 'the rotor 4 in the same direction- Rings v24 keep plates 23 in close contact with the innerf walls of body member 1. As each plate 23 passes the intake port 7 it produces a suction which causes the atmospheric pressure to force liquid through pipe 33 into the pump; the liquid is carried along by plates 23 and discharged through port 9 in the manner well known in rotary pumps. I am aware that pumps have been made which embodythe broad lidea of a circular chamber containing an eccentrically\ placed rotor carrying a number of valve plates, but I believe that I am the first one to employ my specific means Jfor keeping the plates in contact with .the inner cylindrical surface and to compensate for wear. Y
lHaving now described my invention what I claim is l 1. In al rotary pump haviiig a cylindrical chamber, a rotor mounted eccentrically therein, a plurality otsubstantially radial slots in said rotor, plates slidably mounted in said slots, means for yieldingly holding said plates against the inner surface of said chamber said means comprising a pair of inwardly extending circular projections con.- centric with respect to said chamber, a ring l surrounding each circular projection and having a greater internal diameter than the diameter of said'projections, resilient means on one side of saidprojections :tor engaging the inner surface. of said rings and means on said plates for engaging the outside olf-said rings.
3. A rotary pump comprising a cylindrical chamber having an intake and an exhaust port, an inwardl -extendingfcircular vprojection on each si e of said chamber and concentric therewith, a rotor eccentrically mounted within said chamber and provided with circular flanges on each side for engaging the sides of the chamber, a plurality of substantially radial'slots in said rotor, plates slidable in said slots, a ring loosely surrounding each circular projection and engaging an end of said plates and resilient means on one 'side of said projections for engaging the interior of said rings.
4;. A rotary pump comprising a cylindricalI chamber yhaving an intake and an exhaust port, an inwardl extending circular projection on each si e of said chamber and concentric therewith, a rotor eccentrically mounted within said chamber and provided with circular flanges on each side `for engaging the sides of' the chamber, a plurality of substantially radial slots in said rotor, plates slideable in said slots a ring loosely surrounding, each circular projection and engaging an end of said plates, a pluralityl of angularly spaced springs on one side of said projections and engaging with the in- `terior of said rings whereby said rings will hold said plates yieldingly against the inner surface of saidcylindrical chamber.
5. -A rotary pump comprisinf a c lindri cal chamberhaving an intake and an exhaust port, an inwardl extending circular projection oneacli si e of said chamber andconcentnc therewith, a rotoreccentr1- cally'mounted within said chamber and provided with circular langes on each side for engaging the sides ofthe chamber, a-plurality of substantially radial slots in said rotor, platesslideable in said slots, a ring loosely surrounding each circular projection and engaging an end lof said plates, a pluralityl of angularly spaced springs on one side of Q said projections and engaging with the'interior of said rino's whereby said rings will hold said plates yleldingly against the inner surface of said cylindrical chamber, and
