UNITED STATES JOHN M. COLLINGWOOD, F WICHITA, KANSAS.

WATER-DRIVEN PUMP.

Application filed June 11, 1921. Serial No. 476,828.

To all whom it may concern:

Be it known that I, JOHN M. CoLLINowool), a citizen of the United States; and

resident of Wichita, in the county of Sedg wick and State of Kansas, have invented certain new and useful Improvements in Water-Driven Pumps, of which the follow ing is a specification.

My invention relates to water currentdriven pumps, andhas for its object to provide pumps for supplying water for irrigation or any other purpose, which pumps are adapted to be driven exclusively by the current of any stream of sufficient size...

The invention consists in the general idea of the construction, arrangement and combinations of parts; and also in the particular construction, combination and arrangement of parts disclosed in the accompanying two sheets'of drawing, forming a part hereof; and also. in certain modified features noted in the following description.

Reference is now had to the drawings, in which-"' i Fig. l is a diagrammatic side elevation of a pump constructed in accordance with this invention; 1

Fig. 2 is an end elevation of the pump, showing the artificial channel in section, and water therein; r

Fig. 3 is an enlarged vertical-section, takenthru one series of lifting-buckets and showing the action of the water;

Fig. 4 is a section, viewed on a line IV-IV of Fig. 3.

In the practice of my invention, I first construct, in the bed of any suitable water-t course, or irrigation ditch, an artificial channel, as 12 on the drawing, using preferably cement-concrete as a material. The bottom of'this channel will be substantially level.

Upon the side-walls 2 of said channel, I- erect a pair of slotted pedestals 3, each adapted to guide a vertically slidable journal-box 4. A brace 5, extended from the wall 2 to one side of the pedestal, supports a bearing 6 for a Windlass-shaft 7 having thereon a drum 8 and a hand-crank 9; One head of the drum is formed with ratchetteethlO, engaged by a pawl or dog 12. A cable 13, secured to the drum, passes over an idler 14, thence down to an eye or hook in a plate 15, attached to or comprised in the journal-box 4, to which the cable is thus secured. This construction is duplicated at each side of the apparatus, except that only one crank and ratchet are required, pro=- vided that the shaft 7 of the drum aforesaid is extended across the pump as shown on Fig. 2, whereby it will actuate the second drum and cable synchronously.

Journaled in the boxes 4, is a tubular shaft 16 which is also the eduction tube of the pump. Mounted on this shaft at spaced intervals, are several series of drop-shaped buckets, 17 Preferably, the material of the buckets is metal; the detail construction for cast metal buckets being fully shown by Figs. 3 and 4, in which the series are shown .as cast integral with a hub 18. It will be noted that in Fig. 3 four bucket elements 17 are employed for each bucket section of the composite series of allied bucket sections; these sections are secured to the shaft 16 so that the sections alternate in a staggered relationship. The shaft 16 is, as shown, composed of short sections having threaded ends which are screwed into the sides of the hub as shown, and ending flush with the hubs inner walls.

An intake aperture, 20, is formed in the advancing side of each bucket, about twothirds of the distance from the axis of rotation to the end of the bucket The inner end of each bucket is provided with a clack-valve 21 hinged upon a pin 22, and provided with an arm 23 on which is adjustably mounted a weight 24. The operation of these weights upon the respective valves, as the wheel rotates, will be fully understood from Fig. 3 without explanation; the direction of the current 0 being indicated by the arrow d.

It will thus be seen that each bucket ele ment 17 radiates from the tubular shaft, being closed at its outer end and the intake port 20 is intermediate said closed end of the bucket and the shaft and through one side of said bucket.

The combination thus far described will constitute an operative water driven pump, inasmuch as the buckets would be propelled by the stream of water, and would pick up water successively and discharge it into the stream-level.

of paddles, 28, which'serve to increase the power absorbed by the revolving parts. paddle extends horizontally between buckets of alternate sections, being thus arranged between two buckets of the intermediate section.

Said valves 27 are each hinged upon a pin as 29, and provided with an arm as 30 on which is a weight, as 31. This weight is adapted to yield to the incoming water,

as shown, but closes the adjacent intake when the latter starts to rise above the This action is desirable when the pump is deeply immersed in the stream, but is nonessential when the immersiondepth is small.

,The paddles 28 are disposed radially and their ends are rigidly secured -to the walls of its moving parts.

Having described the invention, I claim, and desire to secure by Letters Patent:

'1. In a water driven pump, a horizontal tubular shaft, bearings and bearing supports therefor; a plurality of bucket sections, spaced apart in parallel planes, each bucket section comprising a hub element rigid to the tubular shaft with four indi-- vidual bucket elements radiating from said hub element; the [bucket sections being al- A ternately arranged in their parallel plane positions from the horizontal shaft or so as to present a passagefor paddles between adjacent bucket elements of the central bucket section of any series of three bucket sections; and paddle elements horizontally connecting between correspondingly positioned bucket elements of the outer bucket sections of such series and passing between adjacent bucket elements of the central lugket section'thereof substantially as speci-' ecy l ports therefor; a plurality'of bucket sections, spaced apart in parallelplanes vertical with respect to said shaft; each bucket section comprising a hub'element rigid to the shaft with four bucket elements radiating from hub; the bucket sections being altern'ately arranged to present a passage for paddles between the bucket elements of the central bucket section of anyseries of three bucket sections; and paddle elements horizontally connecting between correspondmglypositioned bucket elements of the two outer bucket sections of such series and pass ing between adjacent bucket elementsof the central bucket section; each bucket element having an intake port in one side element thereof intermediate its closed outer end and I said shaft, an exhaust port communicating between the inner end of said bucket and the :shaft and automatic valveimechanisms, one for each intake and onefor each exhau port substantially as specified;
