WATER-WHEEL.

To all Ill/1101M it "lit/by concern.-

Be it known that we, WILLIAM Bonxnnand J U IUs BOEKEL, citizens of the United states, the countyofPhiladelphia and State of Pennsylvania, have in others skilled in the art to which it appertains to make and use the same.

The said casing A- is passage A a cylindrical water-redisengaging the parts.

provided with a vertical lnicating with the said ceptacle, and the circular hollow body of said casing above the said passage is provided with an annular. expansion A to prov1deroom for the heavy annulus Mof the water-wheel, hereinafter described, ,and with a central outward extension A in line with the axis of the waterwheel corresponding to the' construction of the said water-wheel, as hereinafter described.

t one point opposite the lower I said wheel the casing is provided with a tubular arm or ofi'set A"; arranged to receive an inclined inlet-nozzle D, held intubuiarcoupling or socket D, which has an annular external flange d, that is perforated to permit the passage of fastening-screws J into screw-threadedrecesses of the outer end of said tubular arm or ofi's'et, which end is presented obliquely upward. is provided with an external annular flange (Z, which serves as a stop and brace, being in contact with the lower. end of the socket I). These .parts D1) are screwed or tightly litted together. The upper part of the body of said casingis provided with a short strong tubular oifset'E, receiving a fixed shaft E, oh which the gear-wheel (J, above mentioned, turns, being held thereto by a screw E having a broad head or cap that overlaps the hub (1 of said Wheel on the outerside. the said hub is extended to be in contact with the end of the said tubular ofiset E. The latter extendingdown to its bore and screw-threaded to receive the stem of an oil-cup F, and the fixed shaft E is provided, in continuation of part of the place by a The said nozzle- The inner end of this passage, with a longitudinal oil-duct e, a

protected by a concentric annular wheel-casing G, which surrounds the same and has a vertical annular flange G extending inwardly from the saidoil-cup to the said I ing is extended downward to form a pocket G covering and protecting a gear-pinion H,

- meshing with the said gear-Wheel to drive the same and carried by the shaft N of the water- Wheel M. This shaft. turns in a bearing cast with the main part of the casing A, said hearing consisting of a forward-extending hub I and a rearward-projecting block J, with the interposed integral rear wall of the casing, the said bearing being bored from front to rear to admit a bushing K immediately surround;-

ing the said shaft. This bushing is provided at its middle with an annular oil-space f supplied from an oil-reservoir L by means of an oil-pipe L, perforated on its sides at Z and extending through apart of the rear of said casing, which is obliquely bored to receive it, to the said oil-space The hub 1 is braced by webs I, cast integral with it and the rear wall of the casing, and is in contact with the rear face of the hub M of the water-udmel M. The bushing K is in contact at its front end with the hub M and at the other end with the gear-pinion H. The shaft N has its forward end a extended in front of hub M, where it receives a nut a, serving to clamp the wheel M and the pinion H tightly in positionagainst the forward and rear ends of the shaft-bearing integral with the rear part of the casing A.

The wheel-casing G is attached to the casing A by screws g, which enter, respectively, the block J and solid studs J, the latter being rigid and preferably integral with the upper part of the rear wall of the casing and arranged on each side thereof a little below the horizontal plane of the center of the wheel (,1 and the wheel-casing G. The top of the oilreservoir L is also a separate piece cemented to the body of said reservoir and to the rear wall of the casing A or attached thereto in any other convenient way. The front wall A of the said casing is also separate from the main casting which constitutes the rear and the greater part of the body thereof, and is held-thereto by screws 0. The few rcmovable parts above men tioned permit easy access to the interior. of any portion of the casing. The fact that by far the greater part of the article beside the wheels is in a single casting insures the maximum strength and durability and facilitates manufacture. The parts which are made separately and attached aresuch as by their position would prevent or greatly impede casting integrally. The wheel M also consists of a single piece comprising, besides the hub M, a thin conoidal web m,liaring therefrom rearwardly to a relatively heavy annulus M having conoidal cups f at properly-calculated intervals all around its pcriphery, these cups being presented outward to receive in succession the jet of water from the nozzle D. The positionof the said nozzlejand of each conoidal cup M is such that of more or less of the water without reaching the apex of the cup, while a more acute angle does not leave sufiicient opening at the outwardlypresented base of the cone, and consequently a part of the jet will strike outside of it, especially in the beginning of impact. This construction insures the passing of the jet very quickly from the apex of one cup to the apex of the next, with no loss of power by the stroke of the water against the side of the cup toward the center of the wheel, since the outer part of each cup shields theinncr part of the cup next heforeit in rotation, the cups being arranged at intervals determined by a line thus drawn from the nozzle, as indicated by Fig. 1, and the positions of the cups and the positions of the said parts being as above stated. The maximum efficiency of a wheel of this kind must depend, other things being equal, on doing away as far as possible with ineffective application of any part of the jet of water, whether carried by the inward strok i above referred to or by eddies incident thereto, which will oppose and diminish the effect of the stroke on the outer side and at the apex and by bringing the jet as nearly as possible to a focus without other direction of liow in the cup, also on making this action continuous, the jet passing quickly from cup to cup 'with no intervals and with scarcely even an instantaneous lessening at any time of the best focal and impulsive effect. The heavy annulus M near the periphery makes this water-wheel also a fiy-wheel, insuring by its momentum evenness of action when there is irregularity in the water-jet or elsewhere and counteracting any such slight differences of force applied as may he represented by the stroke on the edge of the cup and that at its apex -in short, insuring perfectly reliable rotation while the water-supply continucs, from whateverquarter this reliability may be threatencd, and continuing such rotation, if necessary, over a briefstop- 1 page of flow. The said annulus is circular in cross-section or of such other form as will have its transverse diameter about equal to its radialdiaineter, using the latter term with reference to the radius of the wheel. This permits the said annulus to have a mass exceeding in weight all the r' at of the wheel without undue extension sidewise, as would be necessary if a fiat ring or similar weight were employed. -()ur construction leaves the annulus at once heavy, inconspicuous, and compact, permits'a. pile of such wheels to be arranged for storage or shipment in relatively small compass and without the sides or edges of any annulus interferingwith others in the of the central ing and the pile, and still insures the'inaximum efliciency of fly-wheel action.

accurately and smoothly. The. Wheel as a whole, and especially the annulus and conical cups constructed as described, constitute the 3 most important parts of our invention.

The general operation is as followsz-The interior of the-nozzle being tapered, as shown, to a narrow neck; the water of the jet is compressed by the force ofthe current behind it and issues eompactly as, a projectile aimed at the apex of eath cup as the cups are presented in turn, practically no water spreading or flying aside before the cup is reached. Its work there being done, each cup on turning beyondthe stroke of the jet drops its charge of water through passage A into the waterreceptacle a, whence it escapss through the outlet-pipe. Oi course. the impact of the water turns the wheel as usual within the casing, and any Water not thus discharged drips from the ascending cups through the surrounding space and the said tacle, the cups beingpresented quite empty to the jet. v

This water-wheel is found very effective for operating an air-pump, but of course may be used with other apparatus or machinery, the pump being'shown merely byway of illustratmg one serviceable application of our invention. For ordinary purposes we make the wheel to Weigh about seventeen pounds, mostly in the annulus M, near the-periphery for greater leverage. 'The gear-pinion and gear wheel are mostconveniently provided part of therearwallof the cas I including passage to the said -recep with cogs in the ratio ofi. one toten. causing converse reduction of speed, though of course wedo not limit ourselves to' this the construction of. gearing described.

In many cities the use of water is greatly Testri'cted by law, hence the importance of devising a water-wheel which will get the utmost possible results from the action -of a small stream under moderate pressure. This We have approximately accomplished.

"Having thus described we claim as new,

anddesire to secure by Letters Patent; is

- 1. A water-wheel in one piece comprising a hub, a thin flared conoidal web, a peripheral annulus and peripheral cups, whereby the greater part ot'the wheel is near its periphcry, in combination with a casing adapted to p the formof said wheel and supporting the same and means for supplying motive fluid ratio nor to our invention, What 'for driving the said wheel substantially as set forth.

2. In combination with a water-wheel and its shaft, a casing therefor consisting of a single casting and a frontplate, the said casting bearings for the said shaft and thickenedparts adjacent thereto and gearing operated by said wheel for driving mechan anism, the said wheel between its hub and periphery being given a flared or conoidal form to allow' space for said bearing and thickened parts, this flared part being thin and the greater part of the weight of the wheel being near its periphery for the'purpose, set forth.

.Intestimony whereof we have signed our names to this specification in the presence of two su bscribi'ng witnesses.
