The invention relates to an elevator for lifting a fluid to a higher level, as water from a stream to a ditch or flume elevated thereabove. 7

5 A general object of the invention isto provide an improved and simplified elevator wherein the load-carrying elements comprise partition members upwardly movable as piswhich'permits the passage of'the conveyor around sprocket wheels or the like, said means applicable to continuous flexible conveyors generally.

Yet another object'istoprovide a'water elevator of the class described which is particularly adapted for use in'inclined lift pas sages. 1

The invention possesses other objects and features of advantage, someof which, with the foregoing, will be set forth or be apparent in the following description of a typical embodiment of the invention. and in the accompanying drawing, in which, V

Figure 1 is a partly sectional side elevation of an elevator embodying the invention and operably disposed. I v

Figure 2 is a sectional view at 2'-2 in Figure 1. j

Figure 5 is a section at 55;in Figure 3. .1 As particularly illustrated, the novel features of the present invention are incorporat ed inthe structure of an elevator unit wherein

wall members

6, 7, 8 and 9 cooperateto,

define a lift passage 11 of uniform cross.- section. As shown in Figurel, said unit is disposed to dispose the passage 11 in angular relation to the vertical, this disposal of the unit being that in which-the same'is utilized whereby the conveyor 17 is arranged to be in efi'ectingthe delivery of water from a stream 12 over a dyke .or bank 13 bounding the same. Shafts 1A and 15 are journalled at opposite ends of the structure and mount rotary members 16 which cooperatively carry a continuousflexible conveyor 17 having a portion thereof longitudinally traversing the passage "11;" Load-supporting piston members 18 are carried by the conveyor 17 for partitioning engagement in the passage 11 whereby they are arranged to raise water thereabove for discharge at the upper pas sage end, a discharge spout '19 beingprovided for effecting a directed delivery of the elevated water. I y

The conveyor-17, it'will now be noted, coinprises a pair 'of laterally spaced sprocket chains 21 of like length, and the members 16 are sprocket wheels for engaging the chains,

wheels of like size being provided on each 70:

the links 23 overlap the links25. A sprocket wheel 27 is mounted on the upper shaft 14 operated by power derived from asuitable source (not shown). A i r Laterally opposite elements 22 ofthe two conveyor chains jointly carry the pistonelements 1'8. As particularly shown, block 85 members29'are mounted on the said chain elements 22 to extend longitudinally thereof, andthe pistons 18 are fixedto the leading ends of said blocks to extend transversely of the chain elements which carry them. The mounting of the blocks 29 is effected by fixing them to the links 23 of said elements22, said links being formed with integral lateral extensions whereby to receive the blocks between the latter. The blocks 29 are mounted to extend solely from that chain side which lies radially outwardly of the sprocket wheels 16 as the chain moves therearound.

The chains '21 extend along the passage Wall 8 in close adjacency thereto whereby the pistons 18 extend transversely from t-he said wall and as partitions in said passage. As shown, these piston partitions comprise plates provided with anti-friction rollers 31 at the edges thereof which oppose the passage walls 6, 7 and 9, the plate being shaped to provide for a maximum degree of partitioning of the passage 11. H

Since the weight of water being elevated by and above a piston 18 will tend to deflect said piston out of its transversely partition I ing relation to the passage 11, means are provicled for bracing such partition again'st deflection during its .operativeness. As particularly shown, such meanscomprises theprovision of brace blocks 32 mounted on the chain elements 22 which immediately, succeed the piston, said blocks cooperating with the blocks'29 to provide brackets behind the piston which are effectively triangular, the various blocks. being appropriately shaped.

In the present instance, two blocks 32 are provided'for bracing operation .at each chain,-

and'sa'idblocksare mounted on the elements '22 which carry'them in the same manner as are theblocks v29. In this manner, an appreciabl'e length of conveyor chain is utilized as partof abracket support'for the piston, said ehain length including a plurality of the pivotally related chain elements 22 and'24. 7

It is obvious that the reaction to the oper ation of the described sectional brace or bracket urges the chain portions thereat toward the passage wall 8:, and meansareprovided to support the chain from said wall for movement therealong. Accordingly, and as shown, like members 33 are mounted on'and between the oppositechain elements 22 which carry :the brace blocks 29 and 32', said members carrying rollers 34: forsen'gagem'ent with; the'passage wall. 8 whereby to slightly space.

the chains from said wall. In the present instance, the members 33 are provided with transverse end flanges 35 whereby they are arranged to'be'fixed to the elements22'by use of the c'hainpins 26, the latter being of the necessary excess length for the purpose.

The now-described structure of-the piston v bracing'means is seen top'rovide for a. passing of the chains around the sprockets by permitting an angular separation of the various "brace block sections, this feature being brought. out in the showing of Figure 1 6 :wall or a side wall. Furthermore, .it is clear that. the disclosedbracing means is advantageously applicable t-o loadcarrying elevments ofconveyor chains generally. 7 'It is noted that in the present instance, the

shafts 14 and 15 are journalled in lateral eX- tensions 36 ofthe passage wall members 7 and 9 at opposite ends of said members. Track members37 are mounted on and along the .ou'terside cram wall member 8 forsupporte ing engagement withthe rollers 34: of thepiston assemblies whereby the chains 21 may be --supported ibetweenthe sprocket wheels 16 Y and externally of the lift passage. In this :manner,-the structure shown comprises a selfcontained elevator unit for installation where'desired. Inpractice, the conveyor assemblywould be driven ;at a speed to 1ninimize the escape of water by thepistons, they need for the equivalent of piston rings thusv being avoided; l i

the advantages of the construction and meth: 0d of use will bereadily understood by thosev skilled in the art to which the invention appertains. While I h aveno'w described the principle of operation, together with the de- 7 vice which I now consider to be a preferred embodiment thereof, it is understood that the device shown is merely illustrative, and "that such changes may 'be made when desired as fall within the scope of the appended claims.
