- WATER-MOTO R.

SPECIFICATION forming part of Letters Patent N 0. 499,269, dated June 13, 1893.

Application filed October 3, 1892. Serial No. 447,633 (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM R. WHITE, a

citizen of the United States, residing at Seattle,

This invention relates to hydraulic motors;-

andit has for its object to provide certain improvements in machines of this character which will render the same much more powerful and durable, and at the same time will provide a construction, whereby the various parts thereof are easily assembled and also separated from each other.

With these and many other objects in view which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawings:Figure 1 is an end View of a hydraulic 'motor constructed in accordance with this invention. Fig. 2 is a vertical transverse sectional view on the line 22 of Fig. 1. Fig. 3 is a vertical longitudinal sectional view on the line 3-3 of Fig. 2. Fig.4 is a detail side and front elevation of a section of the buckets.

Referring to the accompanying drawings A represents a circular or cylindrical casing terminating at the bottom thereof in a discharge neck or spout B, said casing being supported upon suitable standards or legs 0 in any desired location or position. Eccentrically journaled within the opposite sides of said casing is the wheel shaft D, upon which shaft is securely keyed the water wheel E, communicating motion thereto and driving the band pulley F, at one end of said shaft, from which the power derived from the motor can be transmitted to suitable machinery. As described the water wheel E is mounted eccentrically within the casing at one side of the vertical center thereof, and is provided with the parallel side peripheral flanges F between which are arranged the water buckets G. The said water buckets G are approximately semi-circular in shape and are formed in separate sections or sets G, as illustrated."

Each section of buckets is provided with the inwardlyprojectingboltsH,whichareclamped by means of the nuts h, in the rim of the wheel so as to removably secure the buckets between the peripheral side flanges of the wheel. The, sections G, are integral castings having a series ofintegral water buckets, and the bases or base platesfrom which the bolts H, project, are curved to correspond tothecurvatu reof the rim of the wheel, so as to snugly fit thereon, and in order to provide a construction whereby the several separate castings or sections can be circularly aligned to complete the water wheel series of buckets. This providesa construction which allows for the removal and replacing of any section of buckets at will, while at the same time simplifying the bucket construction of water wheels by rendering the same much easier to manufacture. Inasmuch as the shape of, the buckets is approximately semi-circular, it will be readily seen that after the same have assumed a position to hold the impact of water jetted therein,that the waterisalmostimmediately turned out of or shed from the same as will be readily apparent.

The casing A is provided in the top thereof and at one side of the eccentrically located wheel therein with the open socket I, extending therethrough and having upon the under side thereof within the casing the wedge inclines J, said socket or opening being also provided with the opposite guide grooves K, designed forthe purposes now to be described. The water pipe L, terminates at one end in the integral reduced jet nozzle M disposed at right angles with the main portion of the pipe, and adapted to be passed into and through the open socket I. At the base of the reduced nozzle M, is formed a binding shoulder N directly below which are the opposite locking lugs O, which lugs are designed to register with the opposite guide grooves in said socket as the nozzle is passed theret-hrough. Now it will be readily seen that after the nozzle has been passed through the open sockets and the lugs thereof have passed below the guide grooves K, that by swinging th'e pipe L a quarter revolutionso as to bring the same directly over and in a line with the top of the casing, that the said locking lugs 0 will ride under the wedge inclines or under shoulders of said socket, and thereby tightly clamp the nozzle and pipe in position,

said pipe being further provided with the securing flanges P which are removably or temporarily bolted to the top of the casing while the motor is in operation. By releasing the pipe L from the top of the casing and swinging the same around until the lugs O align with the grooves K, the nozzle can be easily Withdrawn.

The water supply pipe L is provided with a spherical air chamber R extending above the same and providing means for allowing the water to be jetted against the water wheel in a steady regular stream. The nozzle M projects downward into the casing and directs its stream against the buckets of the wheel upon that side farthest from the side rim of the casing, the eccentric disposition of the wheel allowing the nozzle to be arranged in this position which gives the greatest power from the jet, the water also receiving some power from the force of gravity. It will be seen that by having the nozzle M, arranged in an approximately vertical plane at one side and near the top of the eccentrically disposed wheel, the jet from said nozzle will have its full head, assisted by gravity, directed into each separate bucket before it reaches the horizontal center of the casing, and also directed into each bucket so that the full force of the jet will be exerted tangentially on the wheel without being thrown into the bottom of the buckets against the rim of the wheel. The water thrown from the buckets finds escape through the bottom discharge or outlet B, but in order to prevent the water from being carried around the casing by the wheel,

a baffle lug or plate S is cast integral with the casing inside of the same at one side of the bottom outlet B and projects to a point in close proximity to the periphery of the wheel to secure the result noted.

It is to be understood that changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

In a hydraulic motor, the combination with the casing having a bottom discharge opening, and the jet nozzle removably clamped within the upper end of said casing; of a wa' ter wheel mounted within said casing and provided with a circular rim and parallel side peripheral flanges arising from opposite edges of the rim, and a series of separate circularly aligned sections of water buckets, each section comprising a series of integrally cast semi-circular buckets and curved base plates fitting the curved rim of the wheel and having inwardly projecting bolts adapted to be clamped in the rim of the wheel, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
