` UNITED ,STATES To all whom it may concern:

Beit known that I, JOHN F. MoNTRoss, a citizen ofthe United States, residing at Peekskill, in the county of Westchester and State of New York, have invented new and useful Improvements in Hydraulic Motors, of which the following is a speciiication.

This invention relates to certain improvements in hydraulic motors or water-engines; and it has for its object to provide a means whereby a large body of water may be brought into proximity with the buckets of a waterwheel by means of a suitable reservoir, and discharged therefrom in small quantities, in an inclined direction, into the buckets of the wheel, which are peculiarly constructed, so as to discharge the water at a high velocity, whereby the full effective power of the water is utilized, as more fully hereinafter specied.

To this end the invention consists, first, in the combination, in a hydraulic motor or water engine, of a rotary water-wheel provided with an annular series of curved tubular buckets at its periphery, leading from a recess at its center and terminating at their outer ends in contracted discharge-openings, with a stationary reservoir located in said recess and provided with an induction-port Aand one or more elongated educti on water-guides, arranged to form the water into on'e'or more columns and direct the same against the inner faces of the buckets, as hereinafter particularly described; second, in the combination, in a water-engine, of a rotary water-wheel, provided with a peripheral series'of inclined buckets leading from a central space or recess and opening outwardly, with the stationary reservoir located within said space, and having a thickened wall in which the eduction water-guide is formed, whereby the water is formed into a column before being discharged upon the buckets, as more particularly hereinafter described and explained.

In the drawings, Figure 1 represents a vertical sectional view of my improved engine, showing the arrangement of the interior of lthe same and the peculiarly-formed buckets of the water-wheel.V Fig. 2 represents a transverse vertical section of the engine, taken at right PATENT OFFICE.

angles to the view represented by Fig. l, showing the construction of the buckets at their internal ends. Fig. 3 represents an internal view of one of the shells of the engine with the water-wheel in elevation. Fig. 4 repre sents an internal view of the other section, showing the water-back7 in elevation. Fig. 5 represents a transverse vertical sectional view of a modification of th`e water-wheel. Fig. 6 represents avertical sectional view of a modification of the engine, and Fig. 7 a rear view of one of the buckets.

The letter A indicates the outer shell or casing of the engine, approximately circular in form, and having a hollow base,B, upon which it rests. The said casii g is constructed of two similar sections, O and D, one of which is rabbeted at its edges, into which rabbet the edges of the opposite section set when the part-s are secured together, the sections being held together by lugs E, provided with screw-bolts F.

The section G is provided withahollow water back or passage, C', which is represented as segmental in shape in the present instance, and which is provided with an induction-port, G, and eduction water-guide H, as more fully here` inafter explained.

The letter K indicates a hollow boss formed at the center of each section of the casing, on the outside. These bosses, at their outer ends, are provided with apertures of a diameter equal to the diameter of the shaft of the wheel hereinafter described, and the said bosses are of such internal diameter to receive a filling of Babbitt or other anti-friction metal, which is cast in around the shaft or a suitable core, to form bearings L for the shaft.

The 'letter M indicates the Water-wheel of the engine. The said wheel is provided with a series of hollow buckets, O, extending annularly around the periphery of the wheel, on one or both faces of the same, leaving a circular space or recess, l?, at the center of the wheel-that is to say, within the wall formed by the annular series of buckets. These buckets are open at their inner and outer ends, the inner ends communicating with the space P at the center of the wheel, and with the interior of the inclosing shells or casing at their outer ends. The said buckets are semicircular, or approximating thereto, in cross-section, Fig. 7, and are gradually contracted toward their outer ends, terminating in narrow openings R. The portions forming the buckets are all curved in the saine direction from the space P, so as to discharge the water tangentially to the wheel, as more fully hereinafter specified, the rounded ends of the buckets permitting the water to be more freely discharged than if they extended in a straight line across the periphery of the wheel.

The letter T indicates an eduction-port extending from the base of the outer shell or casing of the apparatus, to connect with any suitable escape-pipe.

When the parts of the engine are all properly tted together, the water back or passage will occupy more or less of the space P at the center of the wheel, according to its size, as more fully hereinafter specified.

The eduction water-guide H is inclined in an opposite direction to the curve of the buckets of the wheel, and is so located that when the engine is in operation water will be discharged through said guide in such manner as to strike the semicircularly-curved portion of the partitions successively as they pass during the rotation of the wheel. That portion of the wall of the water-back through which the guide H extends is sutiiciently thick to permit the guide to be made of proper length to form the water into a solid column, which strikes the buckets, whereby the full effect of the momentum of the water is obtained.

In the modification shown in Fig. 5 of the drawings the exterior or inclosing casing is omitted, and the shaft of the powerwheel is journaled in bearings U U in the upright standards V V. In this case the water-back consists of a cylindrical tinme or chamber setting in the recess in the face of the wheel and suitably supported, the said iiume being connected with a suitable water-supply and provided with eduction-ports to discharge the water into the buckets.

The degree of curvature of the buckets of the water-wheel will be varied, according to the diameter of the wheel and the number of eduction-ports H, with the quantity of water to be obtained and the power required in the engine.

The driving-shaft of the engine may be provided with one or more pulleys for belts, or may be provided with other gearing for the transmission of power.

The engine in the present instance has been described and illustrated as a vertical engine but it is evident that by proper modification my improvements could be applied to and employed with equal advantage in a horizontal engine.

The operation of my invention is as follows: The port G is connected with a suitable pipe communicating with a proper water-source,

and provided with a valve, by which the iiow of water may be controlled and regulated. Upon allowing the Water to flow into the waterback it first fills it, and is then discharged under pressure corresponding to the head of water, with more or less force, upon the curved part of the buckets, (indicated by the letter S in Fig. 1 of the drawings.) The momentum of the discharged water causes the wheel to rotate in a reverse direction to the curves of the buckets. The water exerts the full force of its momentum as it enters the buckets, and by reason of their contracted outer discharge ends its flow is checked temporarily, so as to get the full effect of the pressure,which causes the water to escape through the contracted escape-openings at high velocity, so as to assist by its reaction the rotation of the wheel.

I am aware that a water-wheel has been provided with a peripheral series of inclined buckets open at ends and one side, arranged around a central chamber, in which terminates a supply-pipe discharging water in an annular jet or sheet, as shown by the patent of E. Buss, granted October 31, 1876; but this is quite distinguished from my wheel, having a series of tubular buckets with contracted dischargeopenings, and is not capable of being driven with effective force by a small column of water, such as is available from the water-works of cities. Its buckets being open at the side as well as ends, there is no retardation of the water, and consequently no condensation of its reactionary power, as in my contracted tubular buckets.

I am also aware that a steam-motor has been provided with a wheel having a solid rim provided with inwardly-projecting teeth arranged to be struck by a column of steam, as in the patent to S. Whitman, granted June 25, 1836; but in such a wheel the steam does not escape directly outward from the spaces between the teeth, and exerts only a force of im pact thereon, while in my wheel the column of water exerts upon the buckets first a force of impact, and then a reactionary accumulated force as it leaves the buckets tangentially, thus utilizing all the power of the water.

Having thus fully described my invention, what I claim is 1. The combination, in a hydraulic motor or water-engine, of a rotary Water-wheel pro- IOO IIO

vided with an annular series of curved tubular buckets at its periphery, leading from a recess at its center and terminating at their outer ends in contracted dischargebpenings, with a stationary reservoir located in said recess and provided with an induction-port and one or more elongated eduction water-guides, arranged to form the water into one or more columns and direct the same against the inner faces of the buckets, substantially as and for the purpose set forth.

2. The combination, in a water-engine, of a rotary water-wheel, provided with a peripheral In testimony whereof I have hereunto set my hand in the presence of two subscribing 1o witnesses.
