CHARLES H. MEYER, OF WEEPING WATER, NEBRASKA.

Specification of Letters Patent. Patented June 2'2, 1916 Application filed September 30, 1914. Serial No. 864,291.

- T aZZwhom it may concern Be it known that I, CHARnEs N. MEYER,

a-citizen of the United States, residing at Veeping W'ater, in the county of Cass and State of Nebraska, have invented certain new and useful Improvements in Windmills, of which the following is a specification.

The present invention relates to improve ments in wind mills; and is particularly designed to provide an improved means for automatically regulating the supply of water in .atank and controlling the operation of the wind mill in conformity therewith.

The invention involves an attachment that is applicable to windmills employing a reciprocating pump rod, and in which a'float .or other device is located in a water tank filled by the pump operated from the windmill. lVhen the pump has filled the tank to l adesired or required height the movement of the float is designed to actuate the attachment of my invention, and through the 'operation of my attachment, the wind mill is thrown out of commission and held inoperative until the attachment is released by the fall of the water in the tank through the float connection.

The invention consists in certain novel combinations and arrangements of parts as hereinafter more clearly set forth and.

pointed out in the appended claims.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of my invention.

Figure 1 is an elevation view of my attachment showing its operative connections to the pump rod, the windmill, and the water lever indicator or float in a. tank.

Fig. 2 illustrates'the ratchet operating devices, detached from the mechanism for convenience of illustration. Fig. 3 shows a conventional windmill and its connections,

- tank 0 in dotted lines, pump D and the'fioat indicated-at E in the tank. while the location of my regulator is indicated at F.

Referring to Fig. 1, the regulator F is actuated through the instrumentality of the pump rod 1 which is provided with a strap 2 secured thereto to form a guide bracket for the pump rod lever 3. This lever 3 is preferably made up of two similar metal plates as 3 and 3", spaced apart but held rigid with relation to each other by rivets or bolts. The free end of the lever 3 is passed between the bracket 2 and rod 1 and is adapted to be oscillated on the pivot bolt 4 by the reciprocation of the pumpv rod 1. The bolt i is rigid with the portion of the tower indicated at B and the lever 3 is free to oscillate thereon. 3

On the same bolt 4 with the lever 3, a rack wheel 5 is pivoted, its hub. 6 being located between the respective plates 3 and 3*, of the lever, and the wheel also is free to revolve on the pivot bolt. An arm 7 is rigidly attached to the rack wheel, and this arm is connected by a cord or wire 8 to mechanism adjacent the wheel A to throw the wheel out of the wind, or out of operative position and thus stop the action of the pump D.

Normally, when the windmill is in operation, these two elements the pump rod lever 3 and the rack wheel 5 are out of connection, but when the tank has been filled to the required level, these parts are indirectly connected to throw the wheel out of commission, and this connection is accom: plished as follows. A weighted lever 9 is PiX'OtGti on a boltlO fixed in the tower frame just below the rack wheel, and a. weight or ball 11 at the upper free end of this lever tends to turn the lever downwardly. The lower end of-this weighted lever has a wire or rod 12 fixedthereto which is connected at'its other 'end with the float E in the tank C. This connection of the wire or rod with the tank may be direct or indirect, but however made, it will be understood that) a rising movementof the float will cause the wire 12 to pull on the lever 9 and swing the weighted end of the lever to the right in F 1. Preferably the lever 9 is extensible and in addition to the main portion 9 the arm 9 is provided which is perforated as at 13. while the arm 9 is slotted asat 14, 1%, and by means of the bolts 15 the length of the le\ er may beadjusted, to increase or decrease the leverage. I

The lever 9 is provided with a fixed arm 16 which swings on the bolt 10 as a pivot,

and this arm is vpivotally connected at 17 to a slotted link 18 which is in turn pivoted at 19 between the two plates 3 and 3 of the lever 3, and by meansof another link 20 this arm16 is pivotally connected at 21 to a pawl 22 also pivoted on the bolt 19 between the two plates 3 and 3" of the lever 3. Additional pivot holes 23 are provided in the arm 16 so'that the pivot point 17 may be changed if required, and an eccentric member 24 is journaled at 25 between the side plates of the lever 3 to limit the movement of the pawl 22. A detent 26 is pivoted on the bolt 10 and swings freely so that it may engage the teeth of the rack wheel 5.

The lever 9 has projecting from its side the lug or projection 30 having the pin or stud 31 to limit the movement of the detent 26 and to force the detent out of engagement with the rack wheel 5, when the water in the tank rises. Bearing against the detent 26 is the flat spring 28 fastened to the pin or stud 27 and bearing against the stud 29,

" which stud keeps the spring in proper position and forces it against the detent.

'When the water in the tank is lowered and the weighted end of the lever 9 swings to the right and allows the detent 26 to come into engagement with the rack wheel 5 and the spring 28 bears against the detent and keeps it in engagement with the rack .wheel until the water in the tank rises, when it is forced out of engagement with the rack wheel by the pin or stud 31.

In Fig. 1 the regulator is inoperative. \Vhen the water level in the tank 0 rises to apredetermined height the wire 12 is pulled down causing the weighted lever 9 to swing "on its pivot 10 carrying the'weighted end of the lever to the right. This movement causes the arm 16 to swing to the right breaking the joint at the pivot 17 between I the arm and the two links 18 and 20. The

to oscillate on its pivot, so that with the pawl held over in position 'to engage the lack teeth, each reciprocation of the rod causes the pawl to engage and turn the rack wheel a tooth, gradually turning said wheel clockwise, with'thedetent 26 preventing reverse movement of-the wheel. As the rack wheel swings around, the arm 7 is pulled around and down to the right in Fig. 1, pulling on the wire 8 which is connected to the windmill gearing in such mannen as to throw the wheel out of the wind, and thus stop the pump rod.

lVhen the level of the water in the tank falls so that the float permits the weighted lever to fall away from the rack wheel and disengage the pawl therefrom, the rack wheel is turned back to normal position and the wheel of the wind mill goes into the 2 wind again and the pump is again started.

From the above description taken in connection with mydrawings it is evident that I have provided an improveddevice which is facile and efiicient in operation, which quickly responds to the different motions of the operating parts, and is simple and durable.

\Vhat I claim is 1. The combination with a windmill, its

pump rod and a movable element, of a regulator comprising a pump rod .lever, a weighted lever actuated by the movable element and a rack wheel connected with the gearing of the windmill, a link pivotedbetween said levers, a pawl pivoted in the pump rod lever a link connecting said pawl and weighted. lever and a detent on the weighted arm pivot for engaging the rack wheel as described.

2. In a windmill regulator, the combination with alever, a rack wheel, and a weighted lever,connected as described, of a pawl pivoted in the lever, a link connecting the two levers and a second link between the weighted lever and the pawl, and a detent on the weighted lever pivot, whereby the pawl and detent are caused to engage the rack wheel as described.

In testimony whereof 'I affix my signa--
