ATTURN EYS 2,729,166 t AUTOMATIC WIND sToP' f I Henry W. Menn, Bishop, Tex. Application January 17, 1951, Serial No. 206,491 1 Claim. (Cl. 103-31) This invention relates to an automatic windmill control mechanism, and more particularly to a mechanism for operating the brake mechanism of the windmill.

The object of the invention is to provide an automatic windmill control mechanism wherein the brake mechanism of the motor will be actuated when the level of water in the storage tank exceeds a predetermined level, to thereby prevent the water from being wasted.

Another object of the invention is to provide an automatic windmill stop which isconstructed so that operation of the pump will be prevented when the level of Water in the reservoir tank exceeds a certain level.

A further object of the invention is to provide an automatic windmill stop which is extremely simple and inexspensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this application, and in which like numerals are used to designate like parts throughout the same:

Figure 1 is a fragmentary, side elevational view of a windmill, showing the control mechanism of the present invention installed thereon;

Figure 2 is a fragmentary elevational view of the windmill shown in Figure 1, and taken on the line 22 of Figure 1.

Figure 3 is a view illustrating certain details of the construction shown in Figure 2, and illustrating the parts on an enlarged scale. 7

Referring in detail to the drawings, the numeral 10 designates a frame, Figure l, which may be made of any suitable material, and the frame 10 has secured to its upper end a horizontally disposed platform 11. A reservoir tank 12 is supported on the platform 11, and the reservoir tank 12 has an overflow pipe 14 connected thereto.

The present invention is directed to a mechanism for stopping the pumping action of a windmill when the level of water in the overflow tank 12 exceeds a certain level, so that the water will not be wasted.

Arranged adjacent to the lower end of the overflow pipe 14 is a cylindrical guide member 13. Removably mounted in the guide member 13 is a bucket 15 which is adapted to receive water that is emitted from the lower open end of the overflow pipe 14.

The numeral 17 designates a portion of a conventional windmill tower, and the windmill tower 17 may include a plurality of substantially vertically disposed legs 18, 19 and 20. A first guide pulley 16 is connected to the platform 11 for a purpose to be later described.

A lever 21 is pivotally connected to the leg 18 by means of a pivot pin 22, as'shown in Figures 2 and 3 and it will be seen that one end of the lever 21 is beveled, as at 23. A pivot pin 25 pivotally connects an arm 24 to the leg 19, Figure l, A bracket 26 is secured to the leg by suitable securing elements, such as a boltand-nut assembly 27, Figure 2. The bracket 26 serves h 2,729,166 "Patent ed Jan. 3, 1956 2 as a guide and is aflapted to receive and hold the lever 21 when it is in its lowered position.

The outer end of the arm 24 provided with a plurality of s aced penings 28, and a weight 29 is adapted to be sus'pe ed from (Site of the 6pe'nings'28.

Secured to th'e tower 17 iS' 1 uide uuey 30, and a cable 31 is trainedpver the guide pulley and over the guide pulley 30. (life and of the came 31 is unheated to the bucket 15, while the other end of the cable 31 is connected to an eye bolt 32 which is secured to the lever 21. Thus, when the water overflows from the tank 12, this water will fill up the bucket 15 to thereby cause the bucket 15 to move downwardly in the guide member 13, whereby the lever 21 will be pivoted about the pin 22. As the lever 21 pivots in a clockwise direction about the pin 22, Figure 3, the arm 24 will drop or pivot in a counter-clockwise direction about the pin 25, due to the weight 29. A cable or line 33 has one end connected to an eye bolt 34 which is secured to the arm 24, and the other end of the cable 33 is connected to the brake mechanism (not shown) which may be conventional, the brake mechanism serving to prevent operation of the windmill. Thus, when the arm 24 pivots in a counterclockwise direction about the pin 25, the cable 33 will operate the brake mechanism to thereby prevent further operation of the windmill pump so that no water will be wasted.

From the foregoing, it is apparent that a windmill stop has been provided wherein when water overflows from the tank 12, the windmill will be stopped, so that there will be no waste of water. Thus, when the water overflows through the pipe 14 from the tank 12, the bucket 15 will move downwardly in the guide member 13 and this will cause the lever 21 to be pivoted in a clockwise direction about the pin 22, Figure 3. This movement of the lever 21 will enable the arm 24 to drop or pivot about the pin 25, due to the weight 29. As the arm 24 pivots downwardly, the cable 33 will be moved downwardly, whereby the brake mechanism on the windmill will be actuated so that further pumping of water will be prevented. When the water level in the tank 12 decreases below a certain level, the assembly can be reset by hand.

The mechanism of the present invention is simple and inexpensive to manufacture and can be readily installed in existing apparatus.

I claim:

An automatic stop means for a windmill comprising a frame, a horizontally disposed platform secured to the top of said frame, a reservoir tank mounted on said platform for receiving water from a wind mill pump, a windmill tower including substantially vertically disposed legs, an overflow pipe connected to said tank, a cylindrical guide member arranged adjacent to the lower end of said overflow pipe, a bucket movably mounted in said guide member for receiving water from said overflow pipe, a first guide pulley connected to said platform, a second guide pulley connected to said windmill tower, a lever having one end pivotally connected to a leg of the tower by means of a pivot pin, a bracket secured to another of said legs for receiving said lever when the lever is in lowered position for limiting downward movement of the other end of said lever, said one end of the lever being bevelled adjacent said pivot pin to provide a shoulder, a cable trained over said pulleys and having one end connected to said lever and its other end connected to said bucket, an arm having one end pivotally connected to another of said legs and said arm selectively supported by the shoulder of said lever, said lever and arm extending substantially horizontally and said arm extending at an angle with respect to said lever, a weight connected to the free end of said arm, said shoulder selectively moving out from under said arm to permit the weight to move the arm downwardly, said shoulder supporting said arm when the arm is on said shoulder, said shoulder being arranged on one end of said lever and the opposite end of said lever engaging said bracket, and a line having one end connected to said arm and its other end adapted to be connected to a brake mechanism on the windmill for stopping the latter when the level of water in the'tank exceeds a predetermined level, the water in said tank overflowing through said pipe into said bucket to apply tension on said cable to thereby pivot said lever and permit said weight to pivot the arm downwardly.
