WATER-MOTOR.

SPECIFICATION forming part of Letters Patent No. 348,504, dated August 31, 1886.

Application filed March 5, 1856.

To all whom, it may concern:

Be it known that l, GUs'rM'us A. TUEEK, a citizen of the United States, residing at Chi'- cago, in the county of Cook and State of lilinois, have invented certain new and useful Improvements in \Vater-Motors; and I hereby declare the following to be a full, clear, and exact description of the same.

My improvement relates to the class of motors which depend lfor their driving power upon the Aforce of the pressure of the watersupply in cities and other places where the water is supplied through mains and delivered at hydrants, and which are commonly used for actuating printing-presses, the bellows of church-organs, scwiugmachines, and the like.

Tater-motors of the class to which my improvement relates comprise, as the essential features, a ease provided with a water-inlet and a discharge opening, and containing a wheel having on its periphery buckets against which the supply-stream plays, iilling them, whereby the weight of the water is utilized in addition to its pressure, to rotate the wheel, the discharge taking` place during the rotation of the wheel from the buckets through the discharge opening; and also agovernor mechanism to regulate the bulk of the driving-stream, and consequently its pressure, in accordance with the speed of rotation required and the amount of resistancehto be overcome in the work to be done.

My improvement contains the lfeatures above enumerated, though, as will hereinafter appear, I provide means for controlling the d riving power by hand instead of governor mechanism.

My invention consists in the general as well as in the particular construction of the valve device through which the water-power for driving the motor is controlled; and it also consists in certain details of construction and combinations of parts ol' the water-motor, all as hereinafter more fully set forth.

Referring to the drawings, Figure l is a side elevation of my improved motor, Fig. 2, a central transverse' section of the same; Fig. 3, a broken view, partly in section, taken on the line 3 3 of Fig. l; Fig. 4, a longitudinal sec` tion of the valve device operated by the gov- Serial No.194,120.

(No model.)

A is the ease, of common lform and construction, having the discharge-opening 'L at its lower end, where it is surrounded by alateral flange, an, and a verti cal flange, x', which afford the seat, and provided with a chamber, B, formed by a web, s, which separates it from the interior of the case, and into the bottom of which an internally-threaded opening, o', leads, affording the inlet-opening at which the connection is made with the water-supply. At a desired point upon the case,on its narrower part, a flange, q, is cast, the opening in which leads into the chamber B, is screw-threaded and coincides with an opening, q', in the web s, leading into the part ofthe case which contains the wheel C.

The construction of the wheel C will be undei-stood by reference to Fig. 2. It comprises two thin metal (preferably tin) disks, p, having their peripheries bent in opposite directions to form anges o, which disks are secured flatwise together and held by means of a hub, a, formed in two parts-one on each side of the wheel-being placed between the bearings iii/,cast with the case A, and upon which suitable oil-cups,m,are provided. rlhedriving-shaft'D revolves in its bearings m with the wheel, and passes through the disks p and hub a. rlhe diverging flanges 0 afford upon the periphery of the Wheel a seat for the buckets D, funnelshaped and shallow, and which are secured in place (preferably about an inch apart) by soldering, or in any other suitable manner.

E is a valve for controlling the stream which plays against the wheel C, and is operated (preferably automatically for the purpose) by the governor mechanism, all as hereinafter particularly described. The valve E comprises a cylindrical shell, Z, having a perforated head, Z, and threaded, as shown, adjacent to the IOO head, a portion of the cylinder being removed from opposite sides toward its center, to afford a transverse opening, 7c, through it, and the end thereof being solid and slotted centrally and transversely to produce a rectangular opening, i. Toward its inner end the shell Z is provided externally with a shoulder, i. The valve E is inserted.into the hollow flange q and through the opening` q', at which it is stopped by the shoulder i, and it is firmly screwed in position, whereby the opening 7c is caused to face the incoming stream of water through the opening r and chamber B, which water must thus pass through the valve E before reaching the wheel G.

The means of opening and closing and controlling the size of the opening i comprise fingers h, of a form to fit closely against the sides of the slot t' by being of a cross-section toward their forward ends equal or nearly equal to the transverse diameter of the slot, and these ngers taper on their adjacent or inner surfaces toward their rear extremities, and are pivotally attached in position by means of screws h', passing through eyes It on the iingers into the solid portion of the cylinderZ toward its forward end. rlhe size of the opening or slot i, by way of which the water-suppl y gains access to the wheel C, isi increased or diminished or entirely closed by spreading apart the forward ends of the lingers or causing them to approach each other, which operations are effected by moving the fingers in directions the opposite to those desired for their forward ends at the tapering extremities behind the pivotal points, and the close t of the fingers at their pivotal points with relation to the Wall of the cylinder Z, is such as to preclude, without packing, the passage of water elsewhere than between the adjacent faces of the lingers. The pressure of the stream tends to maintain the orifice i, between the fingers h, open for its passage,and the closing thereof is effected by the action of the governor,hereinafter described,by means of the wedge F,slid ing in guides x2, and extending between the tapered ends of the fingers V7L, and secured upon the end oi' a piston rod or stem, G, having a ball,g/,at its extremity, and extending through the head Z into the cylinder Z. Diverging arms H H extend upward and backward from the lflange and afford bearings for a rotary' governor-shaft, I, carrying toward one projecting extremity pulleys g2 g3, to be connected, respectively, by means oi' a suitable belt, g, with pulleys g g' on the corresponding projecting end of the driving-shaft D', the relative sizes of the pulleys being such as are commonly provided in devices of the present kind. The opposite projecting end of the shaft D carries pulleys, as shown, to receive Vthe belt through the medium of which thepowerofthemotoristransmitted. Theshaft I carries, to revolve with it, between the arms H H and adjacent to the arm H,a recessed or grooved and longitudinally-sliding collar, K,

and adjacent to the arm H the governor L, a spiral spring, M,which surrounds the shaft, intervening between the governor and the collar K, being held between the latter and a collar, z. The governor comprises balls f upon the ends of a transverse rod or rods, .f, threaded toward the extremities, and extending from a casting,-N,secured upon the shaft and carrying pulleys e, over which pass chains or belts O, connected each at one end to the collar K, and at the opposite end to a ball,f. The opening in each ball f, through which the rod f passes, is enlarged toward its outer ends to afford a shoulder, z, and Ymake room for a spiral spring, P, surrounding the rod f', and having its seat against the shoulder z', and to receive a nut, P', forming the means for confining the spring l at its outer end, and for preventing the separation of a ball, j", from the rod, owing to the stop provided by the shoulder z. The arm H has a lug, eZ, on its inner side, to which is pivotally secured a casting, B, having arms d to embrace diametrically the collar K at the groove thereon, which arms carry toward their extremitiespins dto enter the groove, thereby affording means for actuating the piston rod or stem G, which'is connected with the casting R, as hereinafter described, by the sliding movement of the collar K, produced by the action of the governor owing to the connection O. The casting R is further provided with an extension, B', Fig. 8, carrying atits extremity a segmental rack, S, and upon this extension a lever, S', is adjustably secured toward one end, the opposite end being provided with a ball, 1', Fig. 7, and the lever carrying on its under surface a tooth, c, Fig. 8, to engage with the rack S and permit the initial setting of the valve E for any given pressure and work to be done, from which the variation in bulk of the driving power produced by thev governor takes place, the piston rod or stem G being connected with the lever S by means ci clamps b, Fig. 7, held together by a central screw, as shown, and provided with the sockets toward their opposite extremities, which receive the balls y y at the adjacent ends of the piston rod or stem G and lever S, and afford thereby a ball-joint or pivotal connection. A rubber tube, c, is connected at one end with the head Z,and communicates through the latter with the chamber B, and at its opposite end with the discharge-opening t, serving .to carry off the drip.

The operation of the mechanism thus described is as follows: The connection with the water-supply at the hydrant having been made at the inlet r, and the piston rod or stern G being adjusted by means of the toothed lever S and rack S to cause the wedge F to gage the opening t' between the fingers h, according to the normal pressure of the watersupply and the amount of work to be done, the Water is turned on, passing in a continuous stream through the chamber B and valve E IOO IIC)

by way of the opening i, which the pressure of water between the fingers 71, tends to maintain open, and strikes against the buckets D, thereby rotating the wheel C. Owing to the large surface presented by each bucket and the comparatively small surface on the periphery of the wheel the water discharges f rom the buckets very freely and without heilig impeded by the periphery through the waste-opening i. Vith the rotation of the wheel the governor L operates through the medium of the connection O to draw toward it the sliding collar l, thereby turning the casting R upon its pivot and forcing the piston rod or stem G and wedge F inward, thus spreading the tapered ends of the fingers 7L and decreasing the size of the opening v5 until the size of the stream becomes inadequate, when the decrease of speed in the wheels rotation, and consequently collapsing eifect upon the governor, causes the collar, by the resilience of the spring M, to slide back, thereby turning the casting It in the opposite direction on its pivotal point and drawing out the piston rod or stem G- and wedge F, thus permitting the pressure of the stream to spread the opening lfand allow thepassage of a larger stream.

The general operation of the governor mechanism being similar to that of other governor mechanisms no further description than the foregoing is necessary to render mine readily understood. The springs P are only auxiliary to the spring lll; but l prefer to use them together, as shown, since thereby the elasticity of the parts is more widespread in the device and the latter is hence smoother in its operation.

The modification shown in Fig. (3 is designed for use where no governor mechanism is provided. It permits the control of the valve E by hand by turning the handle Il on the stem G, which is coarsely threaded to screw in and out ol'the head Z and connected with the wedge F by means of a swivel-joint, b.

I do not in the present application claim, separately, in the watermotor, the waterwhecl constructed as shown and herein described, as I int-end that it shall form the subject of a separate application for Letters Patent, nor is the mechanism herein shown and referred to as the governor 7 mechanism, claimed otherwise than in combination with novel features ofthe motor, as it is considered in itself', in the main, to be old.
