T0 obll. whom it may concern:

Be it known that L'Josnrn L; MARINER, a: citizen *of the United States ,residing at: Gold 9 HiIL'in-the county of-Jackson and State of Oregon, have invented a new and useful Hy' draulic Motor, of which the following is a;

, specification.

ings.

This-invention relates more particularly to that type ofmotor popularly known as "rotary impact, wherein one or more streams of water are directed by suitable nozzles:

against a rotary wheel.

One of the objects of the-inventionis to provide a novel construction wherein the dis-- acharged water after having acted upon the.

wheel is directed away from the same, there-i by obviating frictional resistance to a very; material degree.

Another object is to provide'an arrange-' Inent wherein the end thrust is obvi atedg and still another object is to provide a =motorthat. can be easily dismembered and wherein the. various parts are readily accessible for repairi orrenewal; I

' An embodiment of the invention that is at. present considered the preferable one is illus trated in the accompanying drawings, where- Figure 1 is a sectional view through the.

:motor. Fig. 2' is another sectional view taken-at rightangles to Fig. 1.

Fig. 3 is a detail perspective view of a portion of the wheel. Fig. 4 is a detail sectional view taken; on the line 4; 4: of Fig. 1.

inner side. I

Arotary wheel 12 is secured to the shaft 8 and is locatedwithin the casing, said wheel; having flat opposite sides and being provided: with peripheral spacedflanges 13 the router;

of the sections 16 are standing guard disks 18, ocated directly' ad' edges .of'which'are'located directly adjacent to the opposite sides of-the annular channel. Undercut buckets 14, disposed in tandem relation, are formedin the peripheralzportions of. the wheel and have peripherally-opening inlet-mouths 14*, that are located between the flanges 13." The-buckets are formed with endwalls 15*, side walls 16*, and bottom walls 17 They arefurthermore provided with laterally-arranged flared discharge-outletsl5, which incline rearwardlyandnopen through the opposite sideszof the wheels, the mouths. thereof being'fiared, asashown particularly in Fig. 4 and designated 18*.{It will furthermore be noted that the discharge-outlets -15 alternately open on opposite sides .of the wheel for the reasons hereinafter given, and their inner :ends' are of .less

width thanthelength ofthe pocket-walls through which they pass, as clearly illustrated in Fig. 4

Stationary hub-sections 16 are carriedby the end walls 10 ofthe casing and surround the shaft 8 on-opposite sides'of the wheels said hub-sections being preferably spaced from the shaft and having water-outlet openings 17 in theirlower sides. "Theiinnerends rovided ith i cutjacent to the opposite side faces .of the wheel and parallel thereto, but preferably's 'aced a slight distance therefrom. The dis s18 have their eripheries located inside the discharge-out ets 15 of the buckets and in spaced relation to the walls of thecasing.

Water is supplied to the motor from a pipe 19, having a semicircular portioneZO, extending partially around and in spaced rela'tion to ,the wall-9 of said casing. Nipples 21., ar-

ranged on the inner side of the semicircularportion 20 of the supplyipe,have threaded thereinto couplings 21*, t at are also threadedintounions 22*, connected tonozzles 22, formed in the wall 9 of the. casing,- the .nozzles projecting through the outstanding nipples .23 of saidcasing into the annular channel and alined with the 1 space. between the flanges '13 of the wheel. Valves 24', arranged i nthe couplingsbet'ween the pipe ZO and: the

wheel-casing, controhthe supplyof .water through said nozzles. The outlet forrthe discharged water is through.the'bottomv of.- the casing by .means of a suitable discharge=pipe 25, and vent-nipples 26, located in the upper portion of the casing, prevent the formation of a vacuum therein.

Water is supplied to the pipe 19 through any suitable head, which may have any pressure desired. This water will thence pass into the pipe 20, and consequently through 'the nozzles 22, the amount being regulated by the valves 24. The water will be projected from said nozzles into the buckets 1 1 and will escape therefrom on opposite sides of the wheel. This alternate discharge on opposite sides will preventthe end thrust uponthe shaft-a very important feature in a wheel of this character. The water discharged from the buckets will be projected over the guards 18, and thus be kept away from the side faces of the wheel, finally passing out through the tail-pipe 25. In like manner the portions of the shaft located within the casing will be protected from the discharging water, and frictional resistance therefrom is avoided to a very material degree. The small quantity of water that does find its way between the guards 18 and the wheel will readily escape through the openings 17. With this structure, therefore, it will be seen that not only is end thrust prevented, but frictional'resistance is greatly reduced. Moreover, the construction is simple and the wheel may be cast in one piece, giving it plenty of driving weight.

It will be clear that the structure can be readily dismembered and that access can be other.

the invention is embodied in the form of a roeasily gained to the various parts. 1 This is 35- particularly true of the nozzles and supplypipe, which are located eXteriorly of the casing, so that the valves are conveniently arranged, and each nozzle is independent of the It will of course be understood that the wheel and water-supply can be duplicated for the purpose of securing additional power, this latter type of wheel being especially adapted to low heads of water having considerable volume of flow.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape,

' proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. In this connection and at this point itmay be stated that while tary impact-motor there are features thereof which are undoubtedly capable of advantageous use in connection with turbines.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is '7 1. In a hydraulic motor, a wheel having spaced peripheral flanges, pockets having closed bottoms, and inlet-mouths located between the flanges, each of said pockets be ing provided with a single lateral rearwardlyinclined and outwardly-flaring discharge-outlet that opens through one side of its pocket, said outlets opening alternately on opposite sides of the wheel.

2. In a hydraulic motor, a wheel having a peripheral series of undercut pockets disposed in tandem and having peripherallyopening receiving-mouths, and end, side and bottom walls, the pockets of said series each having a single rearwardly-extending outwardly inclined discharge outlet opening through one of the side walls of the pocket and of less width than the length of the pocketwall through which it passes, said outlets flaring outwardly.

3. In a hydraulic motor, the combination with a casing comprising an annular wall and end walls detachably secured to the opposite edges thereof, of a shaft extending across the casing through the end walls, a wheel mounted on the shaft in spaced relation to the end walls and having a peripheral series of b uckets provided with outlets through the sides of said wheel, means for supplying motive fluid to the buckets through the annular wall, hubsections carried by the end walls and detachable from the casing therewith, and guarddisks carried by the inner ends of the hubsections and located on opposite sides of the wheel directly adjacent thereto, said disks terminating short of the discharge-outlets and being removable with the end walls and hub-sections.

4. In a hydraulic motor, the combination with a casing comprising an annular wall and end walls detachably secured thereto, of a shaft extending across the casing through the end walls, a wheel mounted on the shaft within the casing and having a peripheral series of buckets provided with inlets arranged inside the annular wall and with discharge outlets opening through opposite sides of the wheel, a supply-pipe extending about the annular wall exteriorly thereof, a plurality of nozzles connected to the supplypipe and the annular Wall and projecting through said annular wall and terminating short of the wheel, hub-sections carried by the said end Walls and removable therewith, said hub-sections surrounding the shaft on opposite sides of the wheel and having wateroutlets in their lower sides, and outstanding guard-disks carried by the inner ends of the sections and located on opposite sides of the Wheel directly adjacent thereto, said. disks terminating short of the discharge-outlets and being removable with the end walls.

5. In a hydraulic motor, the combination with a casing having an annular wall pro vided with an annular recessed channel in its inner side, of a shaft, a wheel carried by the ITO channel, buckets formed in the eripheral portion of the wheel, said buckets aving inlet-openings between the flanges in line with the recessed channel and having outlets opening through the sides of the Wheel, a supplypipe ,surrounding'the annular Wall exteriorly thereof; and a plurality of nozzles connected to the pipe and extending through the annu- IO my own I have hereto affixed my signature in the presence of two Witnesses.
