IMPROVEMENT IN WATER-WHEEL GOVERORS.

To all whom it may concern Beit known that I, J. A.,WHITMAN,of Auburn, in the county of Androscoggim and 'State of Maine, have invented anew and improved Water-Wheel Governor; and I do he'reby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being vhad to the accompanying drawings, forming part of this speciication.

' The object of this invention is to provide certain improvements in governors, whereby a greater and more prompt movement of the gate may be effected by the changes of the governor than can be done with those now in use.

The invention -consists of a combination, with the driving-mechanism for the governor, the gate-operating devices, and the governor, of a double-acting vibrating pawl, under an arrangement whereby it is changed to work'the ratchet connected with the gateoperating devices either way, the said pawl being worked by the directiaction of the governor-driving mechanism, thereby relieving the governor of all labor, except the changing of the pawl.

The invention also comprises an improved construction of the governor, whereby the `resistance of the 'A air upon a pair of pendent hinged revolving wings is imade use ot', mainly for working a .vertically-sliding hub on a revolving spindle, to obtain the required reciprocating motion. v

Figure 1. represents a side elevation of my improved governor, partly sectioned, and

Figure 2 represents an end elevation of the same.

Similar letters of reference indicate corresponding parts. l

A represents the driving-shaft, for operating the governor. It may be operated by a belt, or other means, from the ihiving-shaft of the water-wheel, in the usual way.

It is provided with a crank, B, with an adj ustablel pin, C. This pin takes into a slotted rocker-arm, I), vibrating on the shaft E, of a ratchet-Wheel, F, having teeth adapted for being worked in either direction, and connecting in any approved way withV the'waterwheel gate, for opening or closing it..

In this case, I have represented a train, G, of gear- 'wheels for this purpose.

His a double-acting pawl or dog, pivoted centrally, in respect of its length, to the vibrating arm D, so as to work above the face of the wheel F. One end is weighted, and the other is providedwith abent spring,

I, the free end of which rises above the other parts' Aof the pawl, so as to be acted upon by the free end of a vibrating arm, K, pivotedadjustably at L, and suspended at its free ends by a rod, M, from the recipro The Schedule referred to in these Letters Patent and making part of the naine.

wheel F, and being moved back 'and forth bythe crank B and arm D, it will turn the wheel to the right, and close` the gate until the motion slackens, so that the sleeve falls and allows the arm K to pass down upon the spring I, so as to disengage the pawl VH from the wheel, which, so long as the motion does not thither slacken, will hold the said'pawlentirely movement of the arm K will carry the other end of it will be turned to the left, and the gate thereby opened again, to admit an increased volume of water, and the speed will be thereby increased again.

It will be seen that by this arrangement, the labor of working the gate is taken entirely oi from the `governor, which being only required to vibrate, the pawl does not encounterr such resistance as to prevent itv-from `working quickly, and that the gat-e, heilig worked by the positive action ot' the' driving-shaft, is not liable to fail of beingmoved.

My improvement in the construction of the govlt, oscillating shafts S, and cranked connections T the said shafts being supported, horizontally, in long bearings, V, at thetop of theshaft'W, so as to be revolved with it, but free to turn in the said bearings under the resisting action of the air on the wings, aided also, to some extent, by centrifugal force.

ernor-sleeve or yoke is arranged for changing the pawl upon the said ratchet-wheel for working itin opposite directions, all substantially as specified.'

2. The combination, with the sleeve X` of a governor, of the pendent wings T, crank-shaftsS, and suitable connecting-rods M, all substantially as specied.

The above speciiication of my invention signed by me, this 5th day of August, 1869. A
