SPECIFICATION forniingn part of Letters Patient No. 292,673, dated January 9, 1801,

` Application flcdJnly 13, 1853. (No model.) I

To @ZZ whom, t may concern:

Be it known that I, J AMES lWIoR'roN, of Norwich, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Governors for Vater- 4Wheels; and I hereby declare the followingto be a full, clear, and exact description of the same, referen cebeing had to the accompanying drawings, forming part of this specicat'o 1.

This invention has reference to' an improvement 'in the construction of machines for governing the water-supply to water-wheels; and it consists in the peculiar and novel application of a friction band and brake, b'y means of which the power is applied in one or the opposite direction to operate the gate, as will be more fully set forth hereinafter.

VFigure lis a view of` my improved automatic water-wheel governor. Fig. 2 is an end view of the same. Fig. 3 is a sectional view of one ofthe driving-gears, the driving-head, and the friction-disk by which the gear is connected with the gate-operating shaft. Fig. 4 is a View partly 4in section, showing the connection of the friction-band with the gear-l wheel and friction-disk. Fig. 5'is a view of the friction-disk, showing the brake-shoe and its connection.

In the drawings, A is the driving-pulley, by which the governor is driven from any constantly-moving shaft, so that as long as-the' water-wheel is in motion the governor will also be in-motion. The driving-pulley Avis secured to the horizontal shaft a, on which two pinions, a', are fixed, one of which gears into and drives the gear B, and the other, through the intermediate pinion, a, 'drives the gear Bin the opposite direction. The gears B andv B are driven constantly in opposite directions. Theyare loosely mounted on the hub of the E and E are friction-disks mountedloose on the shaftD. The gear B is connected with the friction-disk E by the brake-band d, one

end of which is connected with the gear-wheel B or B, and the other with the friction-'disk E or E', the direction of the motion being such that the brake-band d is kept open until resistance is encountered by the friction-disk E, so that one end of the band is held when the constantly driven gear-wheel B draws the brake-baud tightly on the periphery of vthe driving-head, and thus communicates the motion to the shaft D. It-will thus be seen that when resistance is appliedto the friction-disk E theshaft D will turn in one direction, and when applied -to the friction-disk E it will turn in the opposite direction, and as the shaft-D is provided with the beveled pinion D",which Y gears into the beveled gear D, secured to the gate-operating shaft, the gate will be moved in one or the opposite direction when the resistance is applied to onel or the other of the friction-disks E or E. This alternate resistance is applied throughthe speed-governor G, which is the ordinary centrifugal ball-governor driven by intermediate gears from the drivinglshaft a, so that any acceleration of the speed of H by means of the lever h, the weight of therod and force ofthe governor being counterbalanced by the weights h', so that the operation of the governor can be adj usted with great nicety. Y

vTo make the governor act with precision and prevent the brake-shoesHH from retaining their positions after the gate has been regulated, the beveled gear I is secured to the shaft D, on the end opposite to the beveled pinion D. The beveled gear I gears into the gear t' on the shaft k, on which the worm l is placed, which gears into the worm-gearm, secured to the shaft n, on which the brake-shoes H H and levers h 7L are secured. The wormgear m is provided with the slots o o, in which studs projecting from a plate. secured to the shaft n pass, so that the worm-gear may be turned nearly one-half of arevolution before the studs bring up against the ends of the slots and operate the shaft a, so as to release the IOO brake-shoe fronifcontact with the frictiondisk. As the worm-gear turns very slowly, sufficient time is allowed for the brakeshoes to be released; and it is only when such release does not take place, and to prevent the gate from being moved too far, that this particular' safety appliance is used.

p is a stop secured to the shaft n, and gis a camshaped disk, a portion ofwhich is cutaway.

ris a hand-lever for turning the disk so as to allow thestop to bear against the saine or pass by the saine, and thereby prevent or permit the turning of the shaft n and the operating of the brake-shoes.

By the use of the brake-bandd and the brakeshoes H the changes in the direction of the governor are made easygvithout sudden stops, so that the strain is brought on the gears and other parts of the governor gradnall y and without shock, thereby insuring durability and freedom from repairs.

Having thus described 1nyinvcntion,I clai n1 as new and desire to secure by Letters Patent- 1. Ina water-wheel governor, the combina tion, with the. inain driving-shaft a and pinions aa, of the gears B and B', inonntedloose' on the driving-heads C (l, the friction-disks E and E', and the strap-brakes Il, constructed to bc operated through the governor', and the brake-shoes Hto regulate the gate, as described.

2. The combination, with the main drivingshaft and its pinions, of the gears B B, the drivi iig-heads C, friction-disks E and E', stra-ps d (l, the governor G, rod g', and shoes II II, constructed to move the shaft D and regulate the water-supply, as described.

3. In a water-wheel governor,.thecombination, with the shaft D, of the driving-heads C C, the gears loosely mounted on the drivingheads, the disks E E, and band-brakes l d, constructed to connect and disconnect the gears, as described.

4. The combination, with the gears B B', driving-heads C C, disks E E', and band-brakes d d, and the brake-shoes H H, niountedon the shaft n and controlled by the governor, ol'

the beveled gear I, pinion l,worml, and woringear mf, provided with the slots o o, constructed to release the brake-shoes, as described.

In witness whereof I have hereunto set 1nyhand.
