.T0 all whom, t may concern:

Be it known that we, AMOs IV. VOODWARD and ELMER E. WooDwARD, citizens of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented a new and useful Improvement in Water-Vheel Governors, of which the following is a specification.

This invention has for its object the production of a water-wheel governor capable of quickly changing the position of a water-gate as greater or less power is used; and it consists in certain new and useful features of construction and combinations of parts, hereinafter described, and pointed out in the claims.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a side elevation of our improved governor. Figs. 2 and 3 are, respectively, an end elevation and a plan view of the same. Fig. 4E is a view of a vertical section thereof through the dotted linie .fr a; of Fig. 3. Figs. 5, 6, 7, 8, and 9 are views in detail of detached portions of the governor.

Like letters of reference indicate corresponding parts throughout the several views.

A is the main frame of the governor, and consists, essentially, of a hemispherical shell A', a form of construction peculiarly adapted to admit of a consolidation of the parts composing our machine, and a horizontal portion i A2, preferably integral therewith and projecting from the outer curved portion thereof, to form bearings for parts to be described hereinafter.

B is a hemispherical wheel rigidly connected with the shaft B, having teeth B2 on the periphery of the same and being included in the shell A. n

AtL is a cylindrical chamber, partially closed i at both ends by means of horizontal annular and having a vertical cylindrical opening A8 therethrough to form a bearing.

O is a horizontal friction-disk of any suitableform and construction, but having the periphery thereof preferably provided with double bevels C inclining toward the axis of the disk. The double bevels C should be faced with leather O2 or other suitable material in order to produce the most satisfactory results. The central portion of the upper side of the friction-disk O has a basin C3 sunk therein, and the central portion of the lower side of the same has* a 'vertical annular boss O1 depending therefrom and preferably integral therewith.

C5 is anoil-passage extending from the bottom of the basin O3 through the friction-disk C and boss C4.

D is a lower horizontal disk-shaped friction-pulley, the dish-shaped portion D' thereof being on the upper side of the pulley and a counterpart of the lower half of the frictiondisk O in order that it may admit and engage with the same.

D2 is a basin in the central portion of the upper side of the friction-pulley D, of proper dimensions to readily admit the boss O4 of the friction-disk O.

DS is a vertical sleeve-shaft continuous with the pulley D and resting on the bushing A", for a bearing whereon to turn. DJl is a horizontal pinion rigidly secured to the shaft B"s and meshing with the wheel B.

Our purpose in devising and constructing the herein-described machine has been to produce a governor the proper parts of which should be and continue, ,though constantly used and too freely and carelessly oiled, sufficiently sensitive to properly perform their functions. Specifically, we have, first, simplified the construction of and great-ly consolidated the various parts composing the gov- .-ernor. {tion-disk C with the sink C3 and the boss C4, the lower friction-pulley D with the sink D2, the upper friction-pulley E wit-l1 the flange E2 Aand boss E2, which constructions and combinations render it impossible for oil or dirt to Secondly, We have provided the fricfind their Way into the friction-surfaces of Thirdly, we have The part-s H, I2, and G2,

acting vertically thereon.

Supposing the governor to be in position IOO IIO

lfor use, and the pulleyN2 to be in connection with the main shaft of a water-wheel by means of a belt, shafting, and gearing, its adjustment and operation are then as follows: Open the gate to its fullest eXtent, letting the governor run, turn the boss O4 of the wheel O2 against the lever P, thereby raising the shaft I endwise until the revolving frictiondisk C is suspended between the friction-pulleys D E, then drop the latch O6 into a slot O3 in the wheel O2, and the adjustment is complete. If more power is required, the balls J 5, the yoke I-I, the shaft I, and revolving friction-disk C will descend and the latter engage with. the friction-pulley D, which is thereby caused to revolve, and,through the medium of the wheel B', shaft B, gear-wheels B2 O7, shaft O, pinion O2, gear-wheel Q, and shaft Q, raise the gate (not shown) connected with the latter. If less power is required, the

- balls J 5, the yoke II, the shaft I, and revolving friction disk C will rise and the latter engage with the upper friction-pulley E, and thereby cause it to revolve, and, through the medium of the parts B', B, B2, O7, O, O2, Q', and Q, lower the gate, all the parts from B to Q, inclusive, obviously revolving in directions the reverse of those mentioned to raise the gate.

As long as the governor is in operation the shaft I, the disk C, pinion G, and all the parts located above said pinion, revolve rapidly and continuously in one direction. The shaft I, disk C, and yoke H also have a slow, nearly constant, very slight vertically-reciprocating motion, simultaneous with the revolving motion to which reference has just been made. The movements of the wheel B', shaft B, gear-wheels B2 O7, shaft O, wheel and boss O2 O4, pinion O2, gear-wheel Q', and shaft Q are oscillatory.
