Application led .Tune 3, 1908. Serial No. $88,519.

To all whom it may concern:

Be it known that I, ARNOLD Tscnmor, a citizen of the United States, residing at Sheridan, in the county of Sheridan and State of Wyomin have invented certain new and useful mprovements in Water- VViieels, of which the following is a. specification.

In many sections of the country where irri ation rs desirable, the fall or slope of the lan is not sufficiently great to admit of dig` ging out ditches from the streams for the purpose of distributing Water over the land, and the object of the present invention has been to ohviate this diiiicult by the rovision of a novel means Where the iihw of the streams may be utilized ihr pumping or raisin the water upon the lands to be irrigated.

he invention further contem lates a device of this character which vf render it possible to derive a head of Water from am stream having banks sufficiently high to allow of darnmlng or raising the water, and which embodies a novel constructionwherehy the wheel or motor is housed Within the dam, and the necessity of construct' e a separate power house is eliminated. e culiar construction provided in the invention also has the further advantage of preventing the lower stream from backirfig up a ainst the dam, so as to reduce the e the wheel in times of flood.

With these and other objects in view that will more fully appear as the description proceeds, the invention consists in certain constructions and arrangements of the p that I shall hereinafter fully describe and the appended claims.

For a full understanding of the invention ective ead upc-n arts g each of the wheel spaces 1 are the end plates then point out the novel features thereof, in 2. In the present instance, these end plates wheel; and, Fig. 6 is an end view-of the modi fied form of wheel.

Corresponding and like parts are referred to in the iollowin description, and indicated in all the views o the drawings, by the same reference characters.

In general, the invention comprises a novel means for mounting a wheel Within a dam, a portion of the water flowing over the crest of the darn, in the usual manner, while the remaining portion of the water flows through the dam and acts upon the wheel, the Water iiowing over the dam gaining a suiiicient impetus or velocity so that when it strikes the apron, it tends to keep back the Water in the lower stream, so as to rer-cnt the latter from backing up against t e dam and reducing the effective head upon the lwheel. It may also be mentioned that the taii race leading the Water away from the wheel discharges upon the apron through the down stream face of the dam, so that the water owing over the dam tends to create a vacuum within the interior thereof and thereby increases the efiiciency of the Wheel. This ower dam which is designated at A may e located either at one end of or at an intermediate point in the length of a main darn B which may be of any suitable construction, the crest of the main dam being somewhat higher than that of the power dam, so that the lat ter constitutes a main spillway. The interior of the power dam is provided with one or more wheel-receiving spaces lace-Ording to the length of the dam and the size of the wheels, and arranged at the opposite ends of are shown as spaced from the walls and are rovided at their top and sides with the and the merits thereof, and to acquire a? ianges 2l which are secured to the wall. l Resting u on the shoulders formed at the knowledge of the details of construction, reference is to be had to the follouing descriL- tion and accompanying drawings, 1n whic Fi re l is a perspective view of a power dam aving the water Wheel mounted therei or upper portion of the dam. 1n, portions bein broken away; Fig. 2 is a l ings longitudinal sectional view through a portion oi the power darn; Fig. 3 is an enlarged detail view of one of the arma cai ing the i wheels mounted thereon.

upper en s of these plates 2 are the bulkheads 3 which are located immediat-ely over the wheels, and form a support for the crest Suitable bear- 4 are provided in the end walls of the Wheel spacca and journaled within these earings is a shaft 5 havin@ a wheel or ach of the buckets ofthe wheel; Fi 4 is asimilar view i wheels com rises a cylindrical bodtP ortion g P P of one of the links connectin rin mounted upon the p ates at opposite i the body encc the wheel Fig. 5 is an end view of the i to form the arms to the 6 which is rigid with the shaft, the ends of portion being extended outwardly peripheral flanges 7 to which the curved arms 8 are pivoted. Corresponding arms 8 at opposite ends of the wheel are connected byp ates 9 which constitute the buckets and are desi cd to be swung either inwardly against t e body portion 6 in an ino erative position, or outwardly away from t e body portion into an operative position. The swin ing end of each of the arms 8 is connecter? by a linl'; 10 to a ring 11 which fits loosely upon a circular dplate 12 adjustably secured to the correspon ing end plate 2. 1n the present instance, the circular plates 12 are shown as rovided with the slots 12 which receive t e shaft 5, and also with the lugs 12b which pro ect through slots 13 in the end plates 2. W en the circular plates 12 are raised to the limit of their upward movement, they are concentric with the shaft 5, and the various buckets constituted by the plates 9 are swun .inwardly into an inoperative position. owever, when the circular plates 12 are moved downwardly so as to occupv an eccentric position with respect to the shaft 5, the various buckets upon the wheels are automatically moved inwardly into an ino rative position as they pass under the bulkhead 3 and are swung outwardly so as to be acted upon by the water Howing through the penstoek 14 as the reach the lower portion of the wheel. T enstock 14 leads from the u per portion of t e dam, the down stream waH thereof being constituted by the bulkhead 3. It will thus be obvious that when the circular plates 12 are moved downwardly, the water flowing throu h the enstock will act upon the buckets o the W eel, so as to revolve the same, the buckets being automatically closed at the u per portion of the wheel and opened when t ey are turned into coperat-ive relation to the penstock. After the Water has acted u on the wheel, it is carried away by the ta race 15 which passes through an openin in the down stream face of the dam, an discharges the water upon the apron 16.

Each of the circular lates 12 is connected b an u wardly extending link 17 to one arm o a be crank lever 18, the two bell crank le veis at opposite ends of the wheel facing in opposite directions and havin their remaining arms connected by second 'nks 19 to opposite ends of the intermediate lever 2O which is pivoted at a central point. These bell crank levers 18 together with the intermediate lever 20 may be arranged within the bulkhead 3 which is shown as havin a hollow construction, and one of the be crank lovers is connectedby a rod 21 to an o erst ing lever 22 at one end of the dam. t will thus be obvious that by suitably mani ulating the operating lever 22, the cirou ar plates 12 can be raised or lowered as desired, and the buckets of the wheel either held in an inoperative position or caused to open to the required degree as they are brought into coto be thrown outwardly into operative posi- A tion by the combined action o gravity and the force of the water as they are turned into coperative relation with the pens'tock. For the purpose of swinging the buckets 9 into a closed or inc erative position as they pass under the bul read, the end plates 2 are provided with the outwardly pro'ecting curved guide ribs 23 which engage t e buckets as they are being elevated at the rear side of the wheel. -T he construction of the dam is identical with that previously described, and it will be obvious that the water flowing through the penstock will operate upon the buckets of the wheel so as to impart motion thereto as heretofore described, and will then be discharved upon the apron of the dam by means of the tail race.

Having thus described the invention, what I claim is:

1. The combination of a dam provided with a wheel space, end plates arranved within the wheel space and formed with shoulders, a bulkhead supported upon the said shoulders, and a wheel mounted within the wheel space, the dam being provided with .means for delivering water to the wheel and discharging i. therefrom.

2. The combination of a dam provided with a wheel space, end plates arranged within the wheel space, the said end plates bein spaced from the walls of the wheel space an formed with liangcs which are .secured thereto, a bulkhead supported b the end plates, a wheel mounted between t e end plates and n'ovided with swinging buckets, and means or moving the swinging buckets into an inoperative position as they pass under the bulkhead and into an o Prat-ive osition as they approach the oposrie side o the wheel, the dam being provif ed with means 'or delivcring water to the wheel and discharging it therefrom.

3. The combination of a dam provided with a wheel space, end plates arranged within the wheel s ace, the said end plates be spaced from t ie walls thereof and rovidlal with flanges which are secured t ereto, a bulkhead supported upon the end plates, a wheel mounted between the end plates and rovided with swinging buckets, a circular plate slidably mounted upon one of the end plates, a rinfy upon the circular Iplate, links connecting the ring to the bue ets of the wheel, and means for moving the circular plate into a concentric or eccentric relation with the axis of the wheel, the dam being provided with means for delivering water to the'wheel and discharging it therefrom.
