ARTHUR GIESLER, OF DAYTON, OHIO, ASSIGNOR TO THE STILlVELL-BIEROE & SMITH-VAILE COMPANY, OF SAME PLACE.

ELECTRIC WATER-WHEEL GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 574,320, dated December 29, 1896.

Application filed April 20, 1896. Serial No. 588,346. (No model.) i v To all whom it mag concern.-

Be it known that I, ARTHUR GIESLER, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Electric Vater-Vheel Governors, of which the following is a specification.

The object of my invention is to provide a sensitive governor for water-wheels which consists, first, in employing a mechanical governor to control an electric current which opcrates the reversing mechanism to turn the gate in either direction; second, to provide two electric circuits which are controlled through the governor, which cuts in and out the respective circuits according to the speed, the said circuits being employed to drive the gate-operating mechanism in reverse direc- 'tion.

A third object of my invention is to provide automatic mechanism for cutting out the circuits soon after the gate mechanism commences to move to prevent racj lgmovement of the governor and also to set the terminals in position for another operation.

The features of my invention are more fully set forth in the description of the accompanying drawings, making a part of this speci- Iication, in which- Figure 1 is a top plan view of my device. Fig. 2 is a front elevation. Fig. 3 is a detailed view of the regulating mechanism operated from the gate-shaft. Fig. 4 is a detailed view of an indicator to show the position of the gates. Fig. 5 is an end elevation of Fig. 1. Fig. (3 is a detailed View of the unshippinglever mechanism. Fig. 7 is a section on line i; 4), Fig. 1. Fig. 8 is a section on line 20 10, Fig. 1. Fig. 9 is a detailed view of the stop mechanism regulating the frictionclutches. Fig. 10 is a detailed view of one of the transmitting-gears. Fig. 11 is an enlarged sectional View through the governor. Fig. 12 is a section on line so 03, Fig. 11. Fig. 13 is a section on line y 11 Fig. 11. Fig. 1a is a detailed view of one of the friction-disks. Fig. 15 is a detailed view of one of the transmitting-gears.

A represents the base of the machine.

0 B represents the driving-shaft, driven from the line-shaft by a belt on pulley B. B is a loose pulley. Power is transmitted by this shaft to the gate-moving shaft 0 through reversing friction mechanism, which consists, preferably, of friction-disks a b, which are 5 5 affixed to a sleeve 0, splined on the drivingshaft. These friction-disks engage, respectively, with the disks (1 6, according to the direction in which said disks are moved. These disks drive, respectively, worms f g, journaled on the shaftB, one screw being right and the other left threaded for the purpose of driving the gate mechanism in opposite directions. Motion is transmitted by worm-wheel G through shaft 15 and gears h t' to epicyclic gear on shaft O, and motion is transmitted from worm f through worm-wheel G, shaft 16, and gears h 2'" to the opposite side of said epicyclic gears. This train of gears 1 2 3 at operates in the same manner as shown in Letters Patent No. 540,094, granted the Stilwell-Biercc & Smith-Vaile Company May 28, 1895.

H represents the governor, whichis driven from shaft B by means of the belt-pulleys 5 6 and bevel-gears 7 S. Said governor is journaled on the shaft H, which is raised and lowered by the action of the balls to operate the contacts of the circuit-terminals. The sleeve 0 is moved in opposite directions by means of So magnets J K, which have a common armature L, operating an armature-lever Z, hinged upon a center l and pivoted at its other end to sleeve L, which embraces sleeve 0 for the purpose of shifting the friction-disks. Mag- 8 5 net J is energized by means of electric circuit X. Magnet K is energized by the circuit Y. These circuits are respectively connected to a common source of electricity Z. The terminals of these circuits are controlled by a 0 common rocking lever M, pivoted at m to the frame of the governor and operated by the rod H in the following manner: N represent-s a yoke 011 said lever M, embracing the neck 17. of the sleeve N, on which the rod H is adjustably secured, preferably by means of screw-threads. The lever M carries terminals 1 s for the respective circuits X Y. These terminals are adj ustable longitudinally on said lever to regulate the sensitiveness of the governor. WVhen this lever is tilted in one direction, one circuit is closed, and when tilted in the opposite direction the other circuit is closed, and when it is in the normal position both circuits are open. In order to bring the lever back to its normal position when moved in either direction, I provide the following means:

represents spur-gear on the sleeve l and O a rack mounted in the frame of the governor, the teeth of which engage with the teeth of the spur-gear.

0 represents a shifting lever operated by the link 0.

P represents the segmental lever, pivoted to arm 2), forming part of the sleeve 1.), which is splined to the box 11 1 represents a gear driving the segmental lever I and receiving motion through gear Q. from gear (1 on shaft G. I do not wish to limit myself to this means for bringing the lever back to normal position, as other means may be employed.

The operation of the electric governor is very sensitive, and in order to prevent excessive movement in either direction I provide the following mechanism to cut out the circuits soon after contact is made and the friction-disk brought into contact with the driving-gear to move the gates:

R S represent mercury-cups mounted upon carrier-arms T, formed integral with sleeve 1 which is swiveled upon a nut U.

it represents a gear-wheel secured to the nut U. The nut U is screw-threaded upon a shaft V, which is provided with a gear Q). These gears are driven by the following train of gears from shaft 13:

9 represents a shaft provided with a friction-disk 10 and receiving motion through gears 11 12 from beveled gears 13 ll upon shafts 15 10. The gears 13 ll are provided with friction-clutches, so as to engage with the shafts 15 and 16 in their forward movement and to be respectively disengaged from them when the opposite gear is being driven. This shaft 9 always moves in one direction, but is driven intermittingly.

17 represents a gear on the shaft 13, driving gear 18, which continuously drives a frictiondisk 11). The friction-disk 1U drives a friction-wheel 20 on shaft 21, which carries a spur-gear 22, meshing with the gear 1, which causes the nut U to descend upon the screwthreaded shaft 2; represents a friction-wheel on shaft El, which drives the gear 25, meshing with gear at on the nut U, which causes the nut to turn upon, the threads of the shaft Y and elevate the nutand carrier-arl'ns'l to their normal position. The gear engages with the shaft 2-1 by means of frictional contact, as shown in detail in Fig. 15, so that when the nut U is raised up to the position desired a suitable stop is provided to terminate the upward movement of the nut U and causes the gear 25 to slip upon the shaft El.

26 represents a torsional spring acting on the fulcrum of the rod M, and through the shaft II upon the governor to prevent undue vibrations of the balls.

27 represents a worm-wheel, and 98 a worm for regulating the tension of the spring 2 3.

Projecting from the sleeve L is a stem 2!). (Shown in Figs. 8 and 9.)

3O 81 represent screw-stops located upon opposite sides of the stem 29 and S'UPPUXECCI in a yoke The yoke is provided with a collar at its upper end which is screwthreaded to the shaft C, while its opposite or lower end is supported in ways 33. It will be observed that the horizontal diameter of the stem 2!) varies and is greatest at its outer end. The screw-threads are on shaft upon which the epicyclic gears and l are mounted, so that whenthis train of gears is turned in one direction the yokesleeve is moved toward the gears, and when turned in the reverse direction it is moved away from them. This moves the stops 3 31 to or from the outer end of the lever, there being suliicient play between the stops to allow the ordinary gate movement within the limits. \Vhen the screw on the shaft O causes the lever 32 to travel outward, the steps 30 or .ll are brought into engagement with the stem 2!) to limit the movement of the armaturelever and the consequent engagement of the friction-disks a I). The object of this to limit the movement of the gates when necessary, either from lack of water to supply the wheel at full opening or to limit the power of the wheel for any cause. These screwstops are adjustable to allow any range of opening desired.

In order to enable the operator to operate the gate by hand,the gear 2, which is loosely mounted upon the shaft (1, is thrown. out of engagement with the gears 33 l bymeans of a shifting lever 31-, operated by means of a weighted lever and eccentric shaft 37. This is used in starting the wheel. In order to prevent the gate mechanism from being operated in case of accident, and also to close down the gate in case of accidents which require it, I provide the following mechanism:

-IO represents a contact-point on the end of the rod M. In case the gm'ernor-bclt should break or other similar accident the contact would drop onto the contact 4.1 and establish the circuit through the lines L2 X and also through the line Y. Thus both circuits X and Y are established at the same time, and the effect of the magnet on the armature is neutralized and prevents any gate movement whatever. In case of accidents to the dyname, such as shortcircuiting or similar causes, so that the circuits X Y become inoperative or anything throwing the load off the wheel, the balls would raise and depress the rod M until contact was made between 410 and 43. This would make contact in circuit In order to cushion the movement of the rod M, I provide the ordinary dashpot 46.

By the construction herein shown and described the control of the gate is operated directly through a governor which directly controls electric circuits which operate the reversing mechanism of the transmitting train of gears. I also provide automatic safety controlling devices to either shut down the gate or prevent gate movement, according to the nature of any emergency which prevents the proper action of the governor.

Mode of operation: When it is desired to start the wheel by hand shifting, lever 35 is turned down, disengaging the gear 2, so that the shaft'O can be turned by hand and the gates opened. The shifting mechanism is then thrown back. The electric current is turned on the circuits X Y, which are normally open. WVhen the balls expand, the circuit X is closed, and the gate-opening is contracted by the operation of the devices already described. When the governor-balls are contracted,the circuit Y is established and the gates are opened wider. At each of these movements the carrier T is quickly drawn down, breaking the circuit to prevent excessive movement, and slowly brought back into contact position for a second operation,the rod M being returned to its normal position during this operation. By this means I obtain a very sensitive governor and am enabled to control the speed of the water-wheel under varying loads in a highly satisfactory manner. I do not wish to limit myself to the specific means described for producing this result except where the same are made specific elements of the claims.
