HYDRAULIC MOTOR.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed August 7, 1905. Serial No. 273,104-

To all whom, it may concern.-

Be it known that 1, JOHN S. GRAY, a citizen of the United States, residing at Springdale, in the county of Stevens and State of VVashington, have invented a new and useful Hydraulic Motor, of which the following is a specification.

invention relates to hydraulic motors, and has for its object to provide a simple, inexpensive, and durable device of this character in which a horizontal water-wheel is mounted for rotation on a suitable supporting-frame with the depending buckets thereof traveling in an inclined flurne or waterway whereby both the weight and velocity of the water will be utilized in driving the motor.

A further object of the invention is to generally improve this class of devices so as to add to their utility and durability as well as to'reduce the cost of manufacture.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, proportions, and minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

In the accompanying drawings, forming a part of this specification, Figure l is a top plan view of a hydraulic motor constructed in accordance with my invention. Fig. 2 is a transverse sectional view of the same. Fig. 3 is a detail side elevation of one of the water-buckets, showing the manner of supporting the same.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

The improved motor consists of a suitable supporting frame or platform 5, provided with a vertical shaft 6, the latter being rigidly supported on the frame by horizontal cross-beams 7, the ends of which are fastened in any suitable manner to uprights or standards 8, preferably driven in the ground at suitable distances from the frame, as shown.

Arranged concentric with the shaft 6 is an inclined flume or waterway 9, to the outer wall 10 of which is secured a circular track 11, said track being preferably formed of anthat portion thereof op- 9 elevated and secured to one of the uprights or standards 8. The inner wall 12 of the flume is connected to the frame. 5 by suitable braces 4, there being similar braces 13, extending between the frame and the standards or uprights 8, so as to securely brace the several parts and revent rotation when the motor is in operatlon. annular shoulder 14 is formed on the upper end of the shaft 6, and engagingsaid shoulder and mounted for rotation on the shaft is a disk or wheel 15, to which are ged, as indicated at 17, a plurality of radially disposed bucket supporting arms 18. The arms 18 are each preferably formed in two sections, having their free ends secured together in any suitable manner and provided with a terminal pin or stud 19, upon which is j ournaled a wheel or roller 20, which bears against the upwardly-extending flange 21 of the circular track 1 1, as shown.

Pivoted to the free ends of the radial braces, at 22, are horizontal bars or bolsters 23, provided with centrally-disposed upwardly-extending lugs or projec tions 24, while hinged, as shown at 25, to the bolsters 23 are the Water-buckets 26. The buckets 26, which may be of any suitable shape or size, are shown in the present instance provided with marginal flanges 27, said buckets being supported in a vertical position, while traveling in the flume or waterway, by means of supporting rods or bars 28, one end of each of which is pivoted to an upwardly-extending ear or lug 28, secured to the disk 15, while the opposite end thereof is pivoted to the central projection 24 of the adjacent bolster.

The projections 24 and the bars 28 are pro vided with one or more apertures 29,whereby said bars may be adjusted vertically to regulate the lateral movement of the buckets, said bars being locked in adjusted position by clam ing-nuts 30.

It wil thus be seen that the buckets 26 are hinged to the bolsters, while the latter are pivotally supported on the radial arms, so that by raising or lowering the inner ends of the rods 28 the buckets may be adjusted laterally with respect to the pivot-pins 22, so as to center the buckets within the flume or waterway, and thereby prevent frictional engagement between said buckets and the walls of the flume.

Secured to the free end of each radial arm is a connecting rod or bar 31, the opposite posite the flume IIO I disk and bucket on the adbetween the the buckets end of which engages the jacent arm, so as to form braces several buckets. By having hinged to the bolsters 23, as arms carrying said buckets travelup the elevated portion of the track and reach a position adjacent-the valve 38 said tilt on the hinges 25 to permit clear the inner wall of the flume, the buckets automatically returning to vertical position assoon as they pass said Wall, as will be readily understood. The rods-are preferably provided with wing-nuts 32, which engage the terminal threads of the rods, so that said rods may be adjusted to vary the throw of the buckets. Journaled on suitable pins deending from the bottom of the disk or wheel 15 are a series of --antifriction wheels or rollers 33, which bear against an annular track or flange 33 and serve to balance the prevent undue friction.

to the wheel or disk 15 is a collar or drum 34 to which is fastened a pair of sprocket-wheels 35, the latter being connected, through the mediumof :a s rocket-chain 36, with a vertical shaft 37 ,so t at the power generated by the motor may be utilized for driving suitable machinery or for other puroses.

The bottom of the flume or waterway is rovidedwith a pivoted gate or valve .38 for controlling the quantity-of water admitted to the flume, so that by swinging the gate downwardly to open position the water will vfiow through the opening in the bottom :of the fiume without affecting the buckets.

The sprocket-wheels may be located above or below the bucket-carrying Secure v wheel or disk and, if desired, the device supported on a suitable raft in a stream and actuated by the current.

From the foregoing description it is thou ht the construction and operation of the evice will be readily understood by those skilled in the art, and further description thereof is deemed unnecessary.
