Specification of Letters Patent.

Re fori-ing more particularly to the drawings, the immoral l5 designates e receptacle which is pzutially .illed Witi liquid. the oeptziele being provided W'bh an overiloiv outle" EG. and an outlet l? for the escape of aii und. vapor.

llotatebiy submerged in the liquid within the receptacle is en element 18) having :i top and o, bottoni 2G Spiieed from each other sind provided between the top :imi bottom. ol"l this element are e plurality olf radially iiisposed ribs or partitions 2l, which :ire coeoil :1t their inner ends `nul ere open et their ont/ir ende :uliueent the periphery of the element. 'llhis element i8 may be constructed in any :lc-,owed or suitable manner either by menig formed as an integral sii-ucture or if heilig eoneirueted in sections secured together. The element 1S is rotatublif ouin ported by ineens of shaft oliiel'i extends through the top 23 oi: the casing and hes secured to it :i Coller 2l, between which olhir anni Jhe top oi the ceiiggi arranged n hearing and by meane of whieh bearirthe elen'ient 'i8 is supported. The shaft :mil theeleinen'.: :1re rotated in my desired oi.' suitable manner, suoli as 'by ineens e, pri leyv 26, secured to one end of ,the shezft f .The element 18 is supijeortecl above the loottoni. 2'? oiI the casing by ineens oli e suitable hearing into which a depending stein 2.1? eonueetod with the element projoets perl( material 30 may he proviiileil to forni a iuid tight joint. f desired e lnfacket Li. having a hearing .o may be provif'lecl to receive the extreiiity of the ilepe ding stein clean-out opening may be provided in the bottoni of the receptacle and. the re eeptnele may be supported by' ineens of suit- :fable lege or supports 34.

Arranged adjacent the periphery' of the rotary element 18 are n e ries of Standards or baille members which are prefembly of e. height to ext-enf. above the top of the element 18 end ere of e. Width slightly greater than the iiidth o the opening of the 18, it is of course to be understood, is aran entrance opening for the liquid in the ective pockets. upported by the standre ar s or bafiles 35 is a member 38,A prefer-r ably in the form of a. plate having vears 39 projecting radially therefrom and which ears are adapted to rest upon the uprights or baffles 35 to be secured thereto b i means of fastenin devices 40 to support t e member and todi ings 41 are provided m the member 38 which are of a size substantially equal to th'e openings 37 inthe top of the rotary element and these openings 41 are spaced from each other in such a manner that the alternate openings 37 in the rotary element 18 will register therewith while the remaining alternate openings 37 in the elen'ient 18 will be closed by the space or solid portion of the element 38 between adjant openings 41.

The bottom face of the member 38 is recessed or cored out as at 42, preferabl adjacent the diametric center thereof, an this recessed portion preferably projects' into the space between adjacent openings 41, as at 43, so that when the element 18 is rotated, the openings 37 therein which do not register with the openings 41 in the member 38 will be brought into communicationwith the extended portion. 43 of the recess 42, so that these extended portions 43 overlap for a short distance the inner ends of the alternateopenin 37. Communicating with the chamber Y ormed by' the recessed or cored ortion 42 is a pipe 44, in which it is deslred' to create a suction.

With this improved construction, the operation is as follows: It being of course understood that all of the parts are arranged as closely as possible so to form tight joints, yet permitting the parts to rotate with. respect to each other without undue friction. l

When the parts are at rest, tho element 18, together with the member 38 and the up rights or baffles 35 being subi'nerged, the

- pockets formed between theradial paititions 21. in the element 18 will be filled. with the liquid, As soon as the element 18 is rotated, centrifugal force will tend tothrow or expel the liquid froi'n the pockets in the clement 18 which are open, that is the pockets which are not closed by the standards orvbaflies 35. As the liquid is expelled from the pockets a partial vacuum or suction will be created in the pocket and inasmuch as the liquid being expelled from the pocket ,at the time when the pocket is il.

old it against rotation. Open! communication with t-he recessed or chambored portion 42 of the member 38, through the medium of t-he extension 43 thereof, this suction or partial vacuum will be manifested in the pipe 44 thereby creating a suction in that pipe. When the pocket passes out of communication with the chambered or cored portion 42 of the memberl 38, it will move into registration with one of the openings 41 in the member 38, that is, the inlet opening 37 of the pocket will register with the opening 41, thereby permitting the liquid in the receptacle 15 to enter the pocket in the member 18 by gravity. When the openings 37,' 41 are in registration, the open end of the pocket at the periphery of the elcment will be in the position shown in Fig. 3 with respect to the upri his or batlies 35, that is, they will be close( thereby so that the liquid will be trapped or confined for a short period of time within the pocket, and'when the pocket is moved to a position that it will be again opened, the liquid in the pocket will be expelled by the centrifugal force to produce the suction, This operation is continued as long as the element 18 is rotated, with the result that certain of the pockets will be filled with the liquid, while the liquid is being expelled from thel other pockets thereby alternately filling and dischargin the pockets as they move into and out o registration with the extension 43 of the cored portion 42 of the member 38,

As the liquid in the receptacle 15 rises, itA

will overflow through the opening 16 and any air or vapor which is formed within the receptacle will pass through the outlet opening 17. i

In order to facilitate thc opcratiim of this mechanism by forcing the liquid into the pockets `when they are alined with the openings 41 `in the member 38. thereby cxpelling the air more rapidly from the pockets, any suitable means may be pro.

vided for catching the liquid as it is cxpelled from the pocket and utilizing this force to direct the liquid into another of the pockets. To that end there may be provided a pipe or .tubular member 45 one adjacent each of the standards or battles 35, and havingan inlet opening 46 adjacent the standard or baliie at that point where the liquid commences to be expelled from theI pocket when the pocket moves away from the standard or u right. This tubular member 45 muy be s aped to extend over the top of the member 38 and is provided with a discharge outlet 47 which registers with a portion of the openings il in the member 38. that as the pocket is advancing foward thel standard or bafile 35i. the liquid which is being expelled from onel pocket will bc, caught by the tubular membcil 45 and conveycd into another pocket vthrough the Thus it will bc manifest fil) opening Ail and just as that pocket is about to be closed by another of the standards or battles 35.

In the form oi' the invention shown in Figs. Sto 1l, the rotary element 48 which (corresponds with the element 18 is provided with a chamber Ai9 at its diametric center, and which chalutier may be of any desi red diameter. The element 4-8 is provided with a plurality of radially disposed openingsI or passages 50 extending troni the chamber r-lfl through the periphery thereo'tl and arranged Within this chamber 49 is an element il. having; a passage therethrough adapted to be liraught into registration with the diametrically opposite passages 50 in the ele-.nent 48. This element 5i is oi a length in one direction substantially equal lo the. diameter of the chamber/t9 and is oi? a wid h in. another direction somewhat less than the diameter ofI the chamber and projecting` laterally from the sides of the member are flanges 53 to forni a, passageway opening vertically through'the chamber 49 so that when the chamber 52 in the element 5l is in registration with the diametrically oppositepassages 50, the space between the flanges 53y of the member 5l will. serve as a means for' permitting the liquid to enter by gravity into the other passages 50 to rceei ve the supplyr of liquid and which supply will be expelled or thrown out of the eliambers Or'passages 50 at the time they are iu regis vtration with the opening 52 in the element 5l, thereby creating a suction in thel chainber 52 which suction manifests itselt' in a pipe or passage 54, having communication with the chamber 52 through the bottom thereof and which pipe or passage :ist comn'uinioates with a pipe leading into the receptacle 15 from the outside of the receptacle. The member 5l is stationary, While the element. 48 is rotatable about the ineinber 51. Thisrotation may be accomplished in aniy suitable manner, such a a bracket 56 secured to the shaft 57, which corresponds to the shaft 22, shown in the form in Fig. l, and a bearing` 58 may be secured to the bottom oi" the element 48 so as to encompass the pipe ola/tiibularmember 54. Thus it will he yseen that the pockets or passages 50 wil/ll be alternately filled and disrcharged of liquid to create a, partial vacuun'i or suction in the pipoy when the passage of the Imember/,51 is in registration. with the pockets or passages 50. In the form of the invention shown in Figs. 10 and l1 in addition to the features already described with respect to the form shown in Figs. 8 and 9, uprights or baiiies 59, similar to the, uprights er baies 85, may.

be .rovided so as to alternately close the poc (ets or passages 5G during the interval of tune that the outlet openings of these by means of pocket or passages, at the periphery ol' the element 4S pass across the. baiiles or standards so as lo routine the liquid within the respective pockets or passages :'O and so that the liquid will be expelled with greater centrifugal ioree. t'rom the pocket when the end of the pocket passes away from the adjacent face ot the standard or baille. 59.

lilith this improved ronstruction, it will be manifest that a very powerful suelion pump will be produced and being submergel, a partial vacuum will be produced by altcrmilely iilling certain of the pockets or chambers with liquid at a predetermined point or-certaip cyclo of revolution oif the rotary clement and then discharging or ex polling the liquid at another predetermined point or cycle of revolution of the rotary element and which partial vacuum or surtion is manifest-d in a suction pipe with which the element has ronnnunication.

While the [deterred 'forms oi' tho inven tion have been herein shown and described, it is to be understood that various changes in the details ot' construction and in the, combination and arrangement of the several` parts may be made without departing from the spirit of this invention.
