INVENTOR BROOK K. MOREHOUSE, OF GRAN Il JUNCTION, COLORADO;

- ROTARY rum.

designed for lifting water, the object of the 1g pum being to-lift at a comparatively low spee( a considerable uantity or weight of water, anda further ject of the invention is a pump of the rotary type to which water will be supplied upon each side and disis charged from each side, thus balancing the pump. A

Thcinvention consists of the novel fea 'tures of construction hereinafter full described, pointed out in the claims and s own in the accompanying drawings, in which,

Figure 1 is a side elevation of the ump. --Fig. 2 is a section on the line 2'2 of ig. 1.

Fig. 3 is a horizontal section taken in the plane of ashaft. Fig. 4 is a side view of a wheel rovided with movable blades. Fig.

5 is a D etail sectional view showing a portion of aside of the pum casing, and an end of one of the blades. ig. '6 "is a vertical section taken'through the circumference of the pump casing. F1 7 is a detail view of a rim ortion; of the w eel showing one of the lades. Fi 8 is a side elevation showing a slightly m o ified form of wheel. 4 Fig. 9 is a detail sectioirthrough a portion of one side of the casing showiii in section an end portion of one of thebla es and illustrating certain modifications in the construction of the cas-' ing and of the blade. 'Fig. 10 is a detail pers ective view of an end portion of one of the 49 ades illustrating the modification "shown in section'in 9.

-In these rawings A represents a casing formed in two halves which are-bolted together, each half or section formingone side 4 of the complete casing. Each section carmesa central hub ortion A and. these hub sections are parall to each other; One of the sections is provided upon its upper por tionjxith an outwardly estending projecting 50 portion A and the other side or section is provided in its lower portion-with a corresponding and oppositely extending projection A.

v The complete casing therefore when mounted upon a base inclines from the per- 7 pendicular, theupperlportion being ofi set,

with res ect to-its lower portion and connected t ereto by curvedside walls, as is most clearly shown in Figs. 2 and 3.

Upon each side of the casing are secured supplemental casings B and B, these casings being 0 positely arranged upon opposite sides. of t .e casing,,as indicated in Figs. 2 and 3. The supply ipe C is provided with two branches C and 2 which lead respectively to the casings B into which they discharge, the branch C dischar ing into the lower ortion of'its casing B and the branch C disc arging swarms- 5m I downwardly into the upper portion of its casing B, audit will be understood that these casings B are upon opposite sides of the easing A and are also upon opposite sides of a central shaft to be hereafter described.

A discharge pipe D receives water from the casings B through branches D and D, which also start from opposite sides of the casing A.

one side of the casin A and a1 alance w eel A disk F is keyed to hub'p'ortions A and this space is made water tight packing rings F set into" the d sk F upon its opposite faces. That (portion of the disk between its periphery an the packing rings F is provided with radial slots prefer abl four in number and ninet degrees apart an these slots are entirely fil ed by laterally movable blades G which work in them. The

blades G I stren then by forming longitudinally upon eac side of the blade a central rib G and I also groove the side and end edges of the blades and place in said grooves a suitable packing G The ends of the blades I refer to round or bevel asshown in Fi 5. also place strips of packing material upon the eripherly of the wheel F which strips exten from'b ado To admit water into and from the casing A I formcurved slots J in the side portions of the casing covered by the supplemental casings B and B so that communication is afforded between theinterior of the casing A165,

and these supplemental casings. I prefer to In the hub portions A is journaledashaftEwhich carriesa' ulleyE' u on form the slots J in pairs leaving between the slots of each pair a web J In Figs. 8, 9 and 10 I have illustrated'some Z slight additions to the construction above F is recessed u on its peripher 'as shown at H and the padlcing material I is a COIltlDu-l f described which are as follows :The wheel 1 through the pipe C and as sai %he eration of the device is as followgz- As the s aft E and wheel F are rotated the blades G by reasonof the slo ing of the sides of the casing A are moved ack and forth thro-u h'the slots of the wheel F. For example, w en a blade is at the extreme top of the casing it will be noon what may be termed the left-hand side (if the wheel F, and will ex- I tend parallel and entirely1 across the projecting. upper ortion A of t e casing. lhis p o ,sitlon is ustrated in Fig. 2. When the wheel has made a one-fourth rotation clockthe blade will extend equally upon each side of the wheel F. 'This o'sition of the bladeds shown in Fig. 3 and ig. 7. When,

a one half rotation has been made the blade will have reached the limit of its travel to the right andgwill be in the" position occupied by the lower blade in Fig. 2, which iosition 1s,

%lso showy the blade when in e ovation in =1 I en th .ee-fourths of a revolution have been completed the blade will have traveled back toward the left-hand side and is againtheposition, withrespect to the wheel F shown m 3 and 7, and the blade will be moving in the direction of the arrow upon the left-hand blade of 3. At the same time 40 the blade diametrically 0 posits the blade whose c cle is being descri ed will be in the same re ative ositzon bpt will be moving in the opposite ction as indicatedby the arrow upon the righthand blade. 46

pleted the blade will have returned to the positionloccupied by the upper blade in Fig.2. The movement of the blades being thus understood their action uponthe water admit- 50 ted to the pum [willbe readily understood.

Water edmitte into the casing B upon the left-hand side of the casing A will be caught as it passesthrough the slots J b an asoending blade and carried over an above the shaft through the projectin portion A and be forced throu'"h the slots ll into. the casing B and into the ranch pipe D, the blade in the meantime passing over to the other side of the casing. The water which had been carried around by said blade cannot however,

pass through the wheel F and is therefore necessarily forced out through the casing B .I At the'ssme time'the blade opposite the.

one justreferred to is acting u on water fed 5 blade moves the revolution of the wheel F is com-' through said grooves andprojecting altersec,4se p downwardly-it carries its supply of water under the shaft E through the portion A of the casingand forces it out through the casing B upon the right-hand side of the pump and through the ipe D. It will be 0 vious'that each blade not only forces eitherover or' under the shaft as the case may be, the Water in advance of it, but also by suction draws in an additional supply of water to be caught by the succeeding blade. It will be obvious'thatas one blade asses through the wheel F and is relieved of its load-upon one-side by the following blade, it takesup an additional load upon the 0posite side and in turn relieves the preceding hide. The pump is therefore alwaysbalanced, the blades performin each an equal amount of 'worku on each side of the wheel F.. Havin thus in ly described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A rotary ump comprising a .asin having hubport1ons, a shaft therein, a whee -u on said shaft, the said casing having paralle projecting portions upon opposite sides of said hub portion, blades carried by the wheel and movable through the wheel, said blades working in said projecting portions, su plemental casings carried by each side '9 the casing first mentioned, the said first'fmentione casinghaving communication with the supplemental casings, a supply pipe hav ing branches, one of said branches 0 euin into a supplemental casing up on one si e, an

- into a supplemental casing upon the o o site side of the first mentioned casing and icliis 1 charge pi es leading from the remaining suplenlienta casings, as and for the purpose set ort ing inclined parallel walls, a. shaft journalsd in sand caslng, a vert1cally arranged wheel. m'ounted upon said shatt, blades carried by fsaid-wheel and movable therethrough, sald blades being reclprocated through the wheel by contact with the inclined Walls of the cas-' in supplemental casings carried by each si e of the main casing, supply and discharge pipesopenin into the lower portions of t e supplemental casmgs upon one side and sup 1 ply and dischar e ipes opening into tlleupper portions 0 t 0 Supplemental casings upon the other ,SldG, as and for the purpose set forthl 3.
