WINDMILL-CONTROLLING MECHANISM.

Specification of Letters Patent.

Application filed September 13, 1912.

Patented Mar. 18, 1913. Serial No. 720,238.

To all whom it may concern:

Be it known that I, JAMES F. SMITH, a citizen of the United States, residing at Phoenix, in the county of Maricopa and State of Arizona, have invented new and useful Improvements in \Vindmill-Controlling Mechanism, of which" the following is a specification.

My invention is an improved automatically operated mechanism for stopping and starting a wind mill and to cause a wind mill and a pump operated thereby to maintain a constant level of water in a tank, the invention consisting in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :Figure 1 is an elevation of a wind mill provided with a controlling mechanism constructed in accordance with my invention. Fig. 2 is a detail vertical sectional View of the wind mill controlling mechanism on a larger scale.

For the purposes of this specification, a wind mill is indicated at 1 in Fig. 1, provided with a vane 2 to throw the wind mill into and out of the Wind and also provided with a lever 3 Which is connected to the vane by means of a rod 4. A weight vessel 5 is suspended from the lever 3 by a rod 6 and moves between vertical guides 7 and is provided in its bottom with an opening 8 and an upwardly opening valve 9 to close the said opening. A locking dog or detent 10 is arranged in one of the guides 7 and is connected, as at 11, to a locking and releasing lever 12 which lever is fulcrumed as at 13 and has a tappet 14 which is arranged directly in vertical alinement with the valve 9.

A pump is indicated at 15 which pump is operated by the wind mill, the usual pump operating rod or connections 16 being employed and this pump discharges into a tank 17. A pipe 18 leads from the tank at a suitable level and is arranged to discharge into the weight vessel 5. A float 19 is movable in the tank and is connected by a cord 20 to the locking and releasing lever 12, the said cord passing over a suitable direction pul- -ley 21.

The operation of my invention is as follows: When the weight bucket 5 is empty,

the vane or controlling element of the wind .mill to which the said weight bucket is connected through the instrumentality of the lever 3, rod 4 and rod 6 puts the mill in operation, thereby causing the pump to operate and to supply water to the tank 17 When the water reaches the required level in the tank 17, water flows from saidtank through the pipe 18 and is discharged into the weight vessel 5, the valve 9 of said weight vessel being normally closed and the water being, hence, accumulated in the Weight vessel. WVhen the weight vessel becomes filled, its weight becomes such as to put the wind mill out of gear and cause it to operate the vane or controlling element opening 8 and raises and opens the valve 9,

thus permitting the contents of the vessel 5 to be discharged. When the tank 17 by the use of water therefrom becomes partially emptied, the float l9 descends and through the instrumentality of the cord 20* causes the lever 12 to release the dog 10 from the weight vessel 5 and thereupon the vane or controlling element of the wind mill againoperates by its own weight to throw the wind mill before the wind and into operative condition and in so doing raises the vessel 5 and starts the pump in operation. Hence, my improved stopping and starting mechanism automatically controls the operation of the wind mill and keeps the tank 17 supplied with a desired quantity of water.

While I have herein shown and described a preferred form of my invention, I would have it understood that changes may be made in the form, proportion and construe tion of the several parts without departing from the spirit of the invention and within the scope of the appended claim.

I claim In combination with a wind mill having a controlling element, a pump operated by the wind mill, and a tank supplied by the pump, a float in the tank, a vertically movable weight vessel connected to the controlling element of the wind mill and raised thereby when the wind mill is in operation,

said weight vessel having a normally closed and released by the float when the level of 10 discharge valve, an overflow pipe leading the water in the tank is lowered. from the tank and arranged to discharge In testimony whereof I afiix my signature into the weight vessel, means to open the in presence of two witnesses.

valve of the weight vessel when the latter is JAMES F SMITH in a lowered position, and locking means for the Weight vessel to hold the same in Witnesses: lowered position, the said locking means be- P. M. PEIROE, ing connected to and operated by the float J. L. MEAD.
