i p This invention relates tothe class of water elevating devices and pertains particularlyto an improved bucket and chain structure for the lifting of :waterfrom a low-elevation and (discharging it ata high point for irri gation orjlike purposes. r

The primary object of this invention is to provide, in a mannerjas hereinafter set forth, an'impro'ved means whereby chain carried water carrying buckets may be tipped at the proper period in their travel to discharge the contents thereof in a more efiicient and economical manner than is done in present elevators.

With the present device, each of the buck:

V ets carried between a pair of conveying chains passes beyond the highest point in the passage of the chain before the bucket begins to move from its upright position so that a proper discharge of the contents thereof takes place Without loss.

i The present invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of the present invention with the understanding, however, that the lnvention is not con-' fined to anystrict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims. r

In the drawing Figure 1 is a top plan view of the water elevator constructed in accordance with the present invention; 7 Y

' Figure 2 is a vertical longitudinally sectioned view of the structure shown in Figure 1, taken substantially upon the line 2-2 of Figure 1, showing atthe. lower portion a longitudinally sectioned well Figure 3 is a detailed view of one link of the elevator chain showing one end of a water bucket attached thereto, the same being in section;

Figure i is a view in end elevation of a portion of a water bucket, showing the chain link attached means;

Figure 5 is a full end view of a water bucket, showing the chain connecting portion in full and the carrying chain in'dotted 130- sition. Y

Referring to the drawing in detail wherein like numerals of reference indicate corre-V spending parts throughout the several views, the numeral 1 indicates generally, a well in connection with which the present water ele vator is shown, the lower portion of the well having mounted therein the frame 2,; uponwhichfis mounted a transverse shaft 3 which carries at opposite ends a sprocket wheel 4-. Upon the well top 5 is mounted a suitable frame work 6 which supports in horizontal position, over and substantiallyparallel with the lower'tra'nsverse shaft 3, the upper transverse shaft 7, this shaft carrying at each end TE NT f a sprocket wheel 8 Passing over and connecting the upper pair of sprocket "wheels '8' with the lower pair of sprocket wheels 4 are the chains 9, certain of the links of each chain having formed integral with the inner faces thereof-an inwardly projectingbracket 1 0. i i Arranged between the parallelchains 9' is a series of water lifting buckets 11; Eachof these buckets hasbolted to its end wall 12, a. plate18 from-the faceiof whicha circular boss 14 extends and through the center of which boss there projects a trunnion pin 15.

This pin may be, as shown in Figure 3, a separate unit havingja'head 16 and having the shank portion thereof extended from'the back of the plate 13'through a suitable aperture opening therethrough and through the boss 14 or if it is desired it may beformed integral with the boss uponthe radial center thereof. t Adjacent the periphery of the boss '14 to oneside ofthe pivotal center thereof thereis formed :a lug 17, l Associated with each of the plates 13 of each bucket is an L-shaped-bracket member 7 indicated as a whole by the numeral 18,the

arm portion 19 of which is; apertured .and-designed to position against a chain link carried bracket 10 to be securedthereto by suit able bolts 20. The other portion 21'of the bracket 18 is substantially circular as shown and is centrally apertured to receive the adjacent trunnion of a bucket, i

That edge of the circular portion 21 of each of the brackets 18 which is lower when the particular bracket is traveling upwardly dur ing the operation of the elevator is formed directly beneath the trunnion 15 to provide an abutment shoulder 22 which, when the adjacent bucket reaches the limit of its move ment, upwardly swings around with the chain link as it passes over the upper pulley 8 and strikes the lug 17 of the bucket plate after the link has passed over the highest point of the pulley and forces the bucket to swing with it during the completion of its passage over the pulley, thus tipping the bucket to discharge the contents thereof into a suitable receiver, such as a trough or a receptacle,

From the foregoing description it will be readily seen that upon the application of power to asuitable drive wheel, as for example, the wheel L3, which may be mounted on one end of the shaft 7 and the elevator operated, the buckets 11 will be carried, when filled, in upright position and will maintain this upright position until after they have passed the highest point over the upper sprocket wheels 8 after which, as previously explained, the shoulders of the link attached bracket 18 will swing around upon the trunnions 15 to engage the lugs 17 of the bucket attached plates and will then gradually throw the bucket over to a horizontal position to bring about complete discharge of the contents thereof. a Due to the manner in which the chain carried members coact with the lugs of the buckets at a predetermined point in the passage or movement of the buckets the present structure is adaptable for use on an incline as well as for conveying watervertically. For this reason the device may be used upon the bank of a stream for carrying Water at an inclination to a'point above the bank for passage into launder or sluice boxes. Elevators of the type at present in use for lifting water are not of a construction which will permit of their being placed at an inclination for conducting water in this manner.

Having thus described my invention, what I claim is I 1. In a water elevator of the character described, the combination with endless carriers having buckets arranged therebetween, of trunnions carrying the ends of said buckets, means carried by said endless carriers for pivotally receiving said trunnions and coacting normally disengaged elements carried by the buckets and endless carrier designed to come together after the'buckets reach the upward limit of their movement to cause tipping of, the buckets.

2. In a water elevator, the combination with endless carriers having water carrying buckets arranged therebetween, of supportiug trunnionsfor the ends of said buckets,

brackets designed to be secured to the endless carriers and each adapted to pivotally receive a trunnion, a stop member carried by each bucket adjacent one of the trunnions, and means forming a part of a bracket for each bucket designed to engage the stop member at a period in the movement of the carriers for tipping the bucket to emptying position.

3. In a water elevator of the character described, the combination with endless carriers having water buckets arranged therebetween, of plates secured to opposite sides of the water buckets, a trunnion carried by each plate, a bracket for and adapted to pivotallyreceive each trunnion, means for detachably securing each bracket to an adjacent carrier, a lug carried by each plate positioned at one side of the adjacent trunnion, and a shoulder carried by each bracket designed to engage the adjacent lug for the tilting of the bucket at a period in the movement of the carrier,

In testimony whereof I hereunto afiix my signture.

JOSEPH S. STINSON.
