ATTACHMENTTO WINDMILLS;

SPECIFICATION forming part of Letters Patent No. 292,030, dated January l5, 1884. Application led July 14, 1883. (No model.)

To aZZ whom, it may concern:

Be it known that I, GEORGE W. MILLER, a citizen of the United States, residing at Clarinda, in the county of Page and State of Iowa, have invented a new and useful Attachment to NVindmills, of which the following is a specification, reference being had to the accompanying drawing.

This invention relates to attachments to wind-wheels for throwing the wheel into and out of operation; vand its object is to provide mechanism possessing superior advantages in point of simplicity, convenience, and general efficiency, by which the wheel will be automatically thrown into and out of operation by a iioat in a tank, and the water in the latter will be automatically kept at the same level.

In the drawing hereto annexed, which represents a perspective view of my invention, A designates the tower or frame-work that carries the wind-wheel B, by which the pitman C is operated, this mechanism being of any suitable construction, and preferably having a house, D, at the bottom of the tower, in which the machinery is arranged. The pitman C of the wind-wheel is connected with the piston E of a suitably-disposed pump, F, that recei ves the water from asuitable source through a pipe, G, and discharges it through a pipe, H, that leads to a tank, I, which, in the present instance, is elevated above the level of a railroad-track, J, and' is adapted to supply water to the locomotives by means oi' any suitable draw-off mechanism.

Ii is a rock-shaft, which has its bearingsLL on a suitableframe, M, and is provided with crank-arms N and O, arranged one at each end and at right angles to each other. The arm N is connected by a pitman, I), with the pitman C of the wind-wheel, sot-hat the said shaft will be operated by the latter, while to' the other arm, O, is pivoted a latch or loop, Q, that will g normally rest in engagement with the teethR- 011 afratchet wheel or disk, S, that is xed on the end of a shaft, T, having its bearings U U on the frame M, and carrying a fixed drum, V, as shown. To this drum V is secured a chain, \V, extending up from near the lower end of the stop-rod X of the wind-wheel, the stoprod being also provided with a lateral pin or arm, Y, that is adapted to engage a lever, Z, that is connected by a rod, A2, with another lever, B2, fulcrumed on a standard, G2, and arranged under the latch Q. A weight, D2, is preferably attached to the lower end of the stop-rod, to assist in returning the same toits normal position. A pivoted pawl, E2, engages the ratchet-disk S, to retain the same from back movement during the` operation of the wind-wheel, and this pawl and also the loop Q are both connected with a lever, F2, that is operated by a line, G2, which passes up and over suitably-disposed pulleys, H2, and is secured to the iioat I2 in the tank I, this line being preferably provided with a weight, J2, at its lower end, below the lever F2, to effect the positive elevation of the iioat as the water rises in the tank.

The operation and advantages of my invention will be readily understood. When water is drawn from the tank, the corresponding fall of the float will raise the lever F2 and the pawl E2 will be lifted from engagement with the ratchet wheel S. The, loop Q is also lifted from engagement with the ratchetwheel, and the latter will be turned with its shaft, as the gravity of the stop-rod X will cause it to fall as soon as the ratchet is released and unwind its chain XV from the drum V. As soon as the stop-rod thus falls by reason of the lower level of the water in the tank, the pitman of the wind-wheel will operate to pump the water into the tank, the float will rise, and the lever F2 will fall and permit the pawl E2 and loop Q to engage the ratchetwheel S again, when the loop Q will be operated by the rock-shaft K,.to wind the chain of the stop-rod on the drum, by turning the shaft by means of the ratchet-disk, the latter being held from backward movement by the pawl E2. During the elevation ofthe stoprod, as soon as its pin Y lifts the end of the lever Z, the lever B2 will lift the loop Q from engagement with the ratchet-wheel S, and the operation of the wind-wheel pitman will cease sufficient water having been pumped into the tank by this time to elevate the float to its normal level.

By this mechanism the whole operation of starting and stopping the windwheel is auto- IOC.

matic, and the mechanism is governed by the simple variations of the level of the iloat in the tank.

I claim as my invention# 1. The combination of the rotary shaft T,

connected with the stop mechanism and carrythe crank ends and operated by the pitman, the loop arranged on the end of the rookshaft, the rota-ry shaft carrying the ratchet-whee1 and drum, the stop-rod having the chain arranged to Wind on the drum, the pawl, the 1ever connected with the pawl and loop, the iloat, and the line connecting the float with the latter lever, substantially as and for the purpose set forth.
