To all whom t may concern.'

Be it known that I, VILLIAM Harrison Lneen'r'r, a subject of the King of Great Britaiin'and a resident; ofv the town of Zion. in the county of Lake, iny the Sta-te of Illinois, United States of America, h ave inven-ted certain new and useful 'Improvements in Fluid Motors, of which the follovving is the specification.

My invention relates to improvements in fluid motors, andthe object of the invention is to devise a motor ci? Water Wheel or turbine type, in which the efficiency Will `be increased, the resulting speed by lwhich the rotor is driven by a given' fluid 'pressure be ing increasedl over that produced bysimilar devices hitherto employed, and it consists essentially of the arrangement and construction of parts hereinafter more particularly described.

Fig. l is a sectional view through my fluid inotor.

Fig. 2 is a plan view partially in full and partially in section, taken on line 2 2, Fig, 1.

In the drawings like characters of reference indicate corresponding parts in each figure. y

l indicates a inain vertical shaft which is held at its upper end in a bearing ineinber 2 located in the supporting traine 3, and at its lower end in :the step' bearing 4l forming part of a base `fiv'aine 5. Around the step bearing 4 is formed a circular table G having annular ball races 7 located ,therein provided with ball bearings 8. l

9 is a cylindrical casing through which the upper end ol' the shaft l extends in proximity to ythe bearing 2. 1 0 is a fluid or `Water supply pipe by which the Water s lied into thecylindricalcasing 9 so as to pass downward through the open lower "end thereof and forni a pressure head.

1l is a circular disehargeineniber coinprising an upper end Wall 12 formed integral Vwith the annular lower edge of the casing 9 and a lower Wall 13 spaced apart from the Wall 12. i Interposed betvveenithe walls l2 and- 1 3 are a ser-ies of curved Walls la and 15, -oriningoutwardly curved dis-l charge peripheral iiozzles 16. It will be understood that the `discharge Inemberjis stationary so that as the Avvater :is `fed from the pipe -10 into the--cylindrioal easing r9, it passes downward into the stationary charge niernleer 1:1 .and isejeeted outward Serial No. 29,084z

"Between the 'upper part-ier of the conical im@ 19 and tllerrer lendof the, cylindrical portion 18' are arranged round its, internal peripherya Seriesk of Sraed apart radial blades 21, arranged to 'receive the irnpaci' of Water ejected vthrou h the nozzleX lr6 hereinbefore described, and by which the l cylindrical portion 18ct the. revolving Inen1- b'er 17 is revolve 'l V22 1s a cover for 4the upper end of the portion 18, such cover being provided with f t a `Central oriiice 28, thrdugh'vvhich the cylindrical casing 9 extends. l d

The lower end of the portion 18 is pro vided with an annular-outwardly extending flange 24. I

25 and 26 are a pair lof Water Wheels provided With a hub 27 secured to the shaft-.1. either by means of pins 28 or lby any other suitahle'ineans desired. The ,lovver'endot the hub 27 isprovided vvith an annular liange 29 opposing the tabl-e 6A and provided with ball races 30 coacting With the halls 8 and races 7 hereinbefore described, lto revolubly inount the hub 27 and the Water` Wheels 2.5 and 26 carried thereby.

It will be noted that the lower Wall 3l forming the body of each Water Wheel 25 and 2o is formed centrally into a conical upwardly extending portion 32 adapted to deflect the Water as it passes downward in an outward radial direction.

Each

Water wheel

25 and 26 is provided with a seriesof radial portions 33.4 At thc outer edge of each

Water Wheel

25 and 26 is provided a series ofdischarge openings 32' radially, as indicated at 36X and then extends forward at an obtuse angle to the radii of the wheel, as indicated at 37, there-- by forming a discharge nozzle 38 at the outer end of the duct 35.

At right angles to the wall portion 3i" extends a wall portion 39 directly opposite to the nozzle 38 to receive the impact of water ejected therefrom.

Between the outer end of the portion 33 and the outer end `of the wall portion 39 is formed a discharge opening 40, and a discharge duct 41 leading therefrom` to the discharge opening 32.

The inner wall 42 of the duct 41 extends in a tangential direction to the circular line upon which the discharge openings of the nozzles 33 are located. The outer wall 43 is concaved inward as indicated, so as to receive a certain amount of the water pressure as it flows from the wall 39 after its impact thereagainst, such water flowing through the discharge duct 41 and being finally discharged through the opening 34 at the pe riphery of the wheel.

44 is a conical casing into which the outer peripheral portion of the wheel 25 extends, having a circular opening 45 at its lowerv end through which the conical upwardly extending portion of the water wheel 26 extends. The upper edge of the conical portion of the casing 44 is curved inward so as to form an Aannular channel 44X which is semi-circular in cross section and in which the outer peripheral portion of the upper water wheel 25 travels.

The upper portion of the casing 44 is provided with a central opening 4G through which the cylindrical portion 18 of the revolving member 17 extends.

From this description it will be seen that as the water passes through the inlet pipe 10 and through the cylindrical casing 9 to form a pressure head, and is'discharged through the nozzles 1G, the revolving member 17 is rotated by means of the impact of water against the blades 21, such water passing downward from the blades and being directed by the conical portion 19 against the radial blades 33 of the upper water wheel 25, which thereby directs the water outward through the ducts 35 so as to have impact against the wall portion 39.

1t will be seen that by the water being carried outward and operating adjacent to the outer periphery of the water wheel 25, greater torque is exerted upon the wheel. lVater, after operating against the wheel portion 39, passes rearward in relation to the direction of rotation of the wheel 25, and is discharged through the discharge openings 34 into the conical casing 44, against the blade 44X which then directs the water into the water wheel 26.

.although l here @ely Sheva iw@ weer wheels mounted upon the shaft 1, it will of course be understood that any number may be employed coupled in vertical series upon the shaft 1.
