T all whom it may concern:

Be it known that we, JAMES OLER, CHRIS- TIAN A. FUGAL, and JUNiUs J. HAYES, citizens of the United States of America, residing at Pleasant Grove, in the county of Utah and State of Utah, have invented new and useful Improvements in Speed-Regulators for Water-Wheels, of which the following is a specification.

This invention relates to-a governor or variable-speed regulator for water-wheels, and has for its object the production of simple and effective mechanism for regulating the supply of water to the wheel to control the speed of motion thereof and also the production of a speed-regulating mechanism of this character whereby the water-gate may be automatic-ally controlled or adjusted by hand as desired.

With the above and other objects in view the invention consists of the novel construction and combination of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a side elevational view of a water-wheel. speed-regulator constructed in accordance with our invention. Fig. 2 is a Fig. 3k is a transverse section on the line 3 3 of Fig. 1,. and Fig. 4 is a transverse section through the gateoperating shaft and the rocker-arm coupling on the line 4 4 of Fig. 3.

Referring now more particularly to the drawings, the numeral 1 designates the frame of the apparatus, which may be of any form, size, and construction to support the operating parts. Journaled in this frame is a horizontal drive-shaft 2, provided at its outer end with a pulley 3, adapted to be connected in practice With the shaft of the water-wheel, and having at its inner end a beveled drivinggear 4, meshing with a horizontally-disposed gear 5, to which is fixed a similarly-disposed spur-gear 6, meshing with a pinion 7 on the lower end of the shaft 8 of a centrifugal governor 9 of that type, provided with balls or weights 10, carried by inwardly and outwardly movable arms 11. At the upper end of the governor is a cap or head 12, operatively connected with the arms to move therewith and to which is fixed the governorstem 13, which is pivotally attached at its upper end to a lever 14, controlled by a spring 15, which exerts a determined resistance to the downward movement of said stem. The construction of the governor is such that when the governor-balls 10 swing outward the head 12 will be drawn downward and depress the stem 13, while upon the inward movement of said balls the stemwill be raised by the action of the arms 11 and the; springcontrolled lever 14.

The gears 5 and 6 are loosely mounted upon the upper end of a speed-regulating shaft 16 and provided with a clutch collar or member 17, and also loosely mounted on said shaft below said gears 5 and 6 is a beveled gear 18, which meshes with the driving-gear 4 and is provided with a clutch collar or member 19. Splined to the shaft between the two clutchcollars 17 and 19 is aclutch member 20, which is adapted to rotate with the shaft and to slide thereon, so as to be positioned between the clutch-collars or to be thrown into connection with either of them. The gears 5 and 18 are constantly driven by the drivin-ggear 4, but rotate loosely on the shaft 16, so that the latter normally remains stationary. The gear 5 and the gear 6, connected therewith, are adapted in practice to tu-rn counterclockwise, while the gear 18 turns clockwise, so that by connecting the clutch member with the clutch-collars 17 or 19 motion may be imparted to the shaft in either direction. The clutch element 20 is annularly grooved in the usual manner to receive pins or studs on the yoked inner en'd of a shifting-lever 21,

which is pivoted at its outer end to the lower l end of the governor-stem 13, which latter is provided with an adjustable coupling 22, by which the length thereof may be varied to compensate for wear and to impart a proper degree of movement to the clutch element.

The lower end of the shaft 16 is threaded for engagement with a vertically-movable nut or reciprocating actuating element 23,

slidable on guides 24, and to which the inner end of a rocker-arm is pivotally connected by pins or bolts 26. The outer end of said rocker-arm carries a sleeve or hub 27, which loosely engages a gate-operating shaft 28, and is provided with a coupling projection 29. This projection 29 is arranged between the side portions or arms of a segmental yoke or coupling member 30, having sleeves 31 embracing the shaft and fixed thereto by setscrews 32. The member is provided with IOO a suitable latch device 33 to engage the member 29 and thereby lock the same to the shaft to positively couple the rocker-arm therewith. As the nut or actuating device 23 moves up or down it rocks the arm 25, thereby oscillating the shaft 28 in one direction or the other; but by releasing the latch 33 the rocker-arm will be permitted to move without imparting motion to the shaft, thus throwing the latter out of action. The shaft carries an arm 34, which may be connected by a rod or other suitable connecting element with the water wheel gate to open said gate when the shaft turns in one direction and close it when the shaft turns in the reverse direction. We have not deemed it necessary to show the connectingrod or element, as the connecting means may vary in construction and arrangement according to the structure of the gate and the arrangement with respect thereto of the governor mechanism. When the rocker-arm is disconnected from the shaft 28, the latter will be uninlluenced by the governor mechanism and is free to be independently operated. A lever 35 is keyed to the shaft and adapted to be operated by hand to rock the shaft for the purpose of manually adjusting the gate. This lever carries a dog 36 to engage a stationary rack 37 to lock the lever and shaft in adjusted position. The pawl is adapted to be projected by a spring 38 and is connected by a link 39 to a bellcrank handpiece 40, by which the pawl may be retracted. A bailshaped keeper 41, pivoted to the lever, is provided to engage the handpiece to enable the pawl to be held out of lockin engagement with the rack when the shaft isoperatively connected with the governor mechanism.

In operation the two gears 5 and 18 are constantly driven by the drive-gear 4, and as the gear 6 turns with the gear 5 constant motion will be imparted to the governor 9. When the speed of the water-wheel exceeds the normal, the action of the governor-weights 10 in iiying outward causes the depression of the stem 13, whereby the clutch element 2O will be shifted into engagement with the collar 17 to lock the gears 5 and 6 to the shaft 16 and impart motion in one direction thereto. The nut-23 will thereby be operated to rock the gate-elevating shaft in one direction through the medium of the arm 25 and to thereby close the water-gate to a greater or less extent to correspondingly cut off the supply of water to the wheel. When the speed of the waterwheel falls below the normal and the governor-balls 10 move inward, the stern 13 is forced upward and the lever 21 shifted to throw the clutch element 20 in engagement with the clutch-collar 19, thereby locking the gear 18 to the shaft 16, which latter will be turned in the reverse direction to correspondlingly move the nut 23 and actuate the arm 25 to rock the shaft 28 to open the gate and admit a greater supply of water to the wheel to increase its speed of revolution. In lorder to shift the clutch member 20 to a neutral position, a vertically-slidable shipper-rod 42 is provided and is pivotally connected at its upper end to the lever 21. This rod carries adjustable contact- collars 43 and 44, arranged, respectively, above and below a contact-arm or projection 45, carried by the nut 23, so that when said nut moves a certain distance in either direction to impart a desired degree of opening or closing movement to the gate the arm 45 will engage the contact 43 or contact 44 and shift the rod 42 to swing the lever 21 and move the clutch element 20 out of engagement with the collar 17 or collar 19, as the case may be. By this means after normal conditions have been restored the shaft 16 will be disconnected from the driving-gears and the gate maintained in the position to which it has been adjusted until the speed of the wheel again falls above or below the normal.

It will be seen that our invention provides a speed-governing mechanism which is positive and reliable in action and adapted to regulate the supply of water to the wheel in a most effective manner to maintain a constant uniform speed of motion thereof and that it also provides effective means whereby the gate may be manually controlled, if desired.
