ALFRED CARLSON, OF KLAMATH FALLS, OREGON.

WINDMILL AND OPERATING MECHANISM THEREFOR.

Application filed April 10, 1915.

To all whom it may concern:

Be it known that I, ALFRED CARLsoN, a citizen of the United States, residing at Klamath Falls, in the county of Klamath and State of Oregon, have invented certain new and useful Improvements in Windmills and Operating Mechanism Therefor, of

which the following is a specification.

The invention comprehends a novel wind mill governor or regulator automatically;

operable upon execessive wind pressure to move the driving wheel therefor into inoperative position.

It is also comprehended to employ brake instrumentalities which are automatically applied when the driving wheel is moved into inoperative positionsaid brake instrumentalities coacting with the regulator aforesaid.

These and such other objects as may hereinafter appear are attained by the novel construction, combination and arrangement of parts to be hereinafter specifically described and claimed.

Reference will now be had to the accompanying drawings forming a part of this specification, wherein:

Figure 1 is a vertical sectional view through apparatus constructed in accordance with my invention. Fig. 2 is a horizontal sectional view parts being broken away. Fig. 3 is a view in elevation of a set collar used in the regulator mechanism 'of this device. Fig. 4; is a vertical sectional view disclosing more clearly the operative connection for manually actuating the regulator member.

Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

Specifically describing my invention, the numeral 1 designates a casing ofa suitable form and size to house the transmission gearing of my device, the casing being provided at one side with a cover 2 bolted or otherwise secured in position thereon. At its other side the casing is formed with a lateral extension 3 on which is rotatably mounted the driving member for the said gearing which, forming the subject matter of my copending application, Serial No. 58,212, filed October 27, 1915, is not herein specifically described. This driving member, in describing the particular embodi- Specification of Letters Patent.

ment of my invention, consists of the wind Wheel 4 comprising the hub 5 composed of an inner and outer section bolted together by the fastening members 6 centrally thereof. This wheel is connected through its hub to the end of a drive shaft 8 revolubly mounted within a longitudinal bore of the extension 8. The inner side of the hub 5 is formed with a brake flange or drum 9 through which the rotation of the wind wheel a is controlled as will be more clearly apparent as this description proceeds.

The casing 1 is mounted upon the turn table 23 of any desired form for suitably supporting the driving mechanism hereinbefore set forth. in my wind mill construction which is suitably supported at the top of a conventional tower indicated 24; in Fig. 1, as is usual. in devices of this type, I employ a governor control for the mechanism consisting of a rudder or vane 25 adjustably secured to an arm or lever 26 which in turn is secured to a horizontal shaft 27, journaled in the casing 1. The lever 26 is directly connected to the shaft 27 through the segmental gear 28 which intermeshes with a corresponding gear element 29 fastened on the shaft 30, the gear 29 having an opposing arm31 secured thereto carrying a counterbalance weight 32 adjustable therealong. Extending laterally from the gear 28 is a roller bearing 33 which is adapted to coact with the cam extremity 34E of a slidable brake lever 35. This lever is slotted atone end and guided in its movements by the projection 36 on the casing" 1 extending into the slot and said lever is pivotally connected at its other end to a lever 37 pivoted at 38 and carrying at opposite sides of its pivot opposing brake shoes 39, 39 coacting with the outer and inner faces of the brake drum 9 on the hub at the inner side of wheel l, hereinbefore described. It may be further stated that the sliding brake lever 35 is nor mally held in its outermost position by means of a spring 4:0 pressing against the cam extremity. hence, normally maintaining release position of the brake shoes 39, 39.

It should be understood in referring to Fig. 1 that the governor parts 25, 26 and 31 occupy the dotted line or vertical positions under operative conditions of the mechanism. Thus the'wind wheel I} is always at work or in the wind so long as the wind pressure on said wheel is not abnormal, un-

. extremity 34 of the brake before described.

less, of course, it is locked in inoperative position by manual means to be described hereinafter. In the aforesaid dotted position, it will be noticed that the rudder 25 is vertically disposed and set angularly on its supporting arm 26 so that when the wind reaches an abnormal pressure it will have a tendency to raise said vane from its vertical position to the horizontalposition shown in full lines of Fig. l and in such position the area of operative wind surface on the wheel and rudder is overbalanced with respect to the vertical axis of rotation of the wind wheel support and naturally the wheel is moved rotatably on the turn table until its edge is in the face of the wind whereupon the wheel becomes inoperative as understood by those skilled in the art to which this invention refers. Immediately the excessive wind pressure falls the rudder 25 drops to its original vertical position adjacent to the turn table support, being actuated in its descent by the'weighted arm 31 operatively connected thereto, which arm is also raised into horizontal position when the rudder is moved in the manner hereinautomatically and obviously the driving wheel 4 is maintained in operation so long as its speed of rotation is not excessive such that it would be likely to injure the driving mechanism operated thereby. In the rising action of the rudder the roller bearing 33 on the segmental gear 28 with which the rudder is connected rides on the inclined cam the roller descends on said incline the lever is moved inwardly actuating the lever 37' and causing the brake shoes 39 to contact with the brake drum 9. Thus when the regulator draws the wheel out of the face of the wind, the brake is simultaneously applied to hold the wheel inoperative.

In addition to the foregoing; I provide manual means for moving the wind wheel 4 into inoperative position and this means will now be described. Upon the shaft 27 in front of the casing l is disposed a collar 4O loose on said shaft and formed with a laterally projecting lever arm 41, said arm having connected thereto one end of a spring 42, the other end of which is connected to thevcasing as indicated at 43. In one face of the collar is formed a groove 44'into which'projects a pin or stud 45 extending laterally from a set collar 46 carried by said shaft adjacent to the collar 40*, the set collar- 46 being held fast on the shaft as by means of the set screw47. The arm 41 has connected thereto a flexible cable or wire 48 passing downwardly through the base of the casing 1 and connected atits lower extremity with a sleeve 49 looselymounted upon the pump or connecting rod 50, which latter is connected to a swivel 51, towhich in turn:

This action takes place lever v 35 and as the pitman 18 hereinbefore vmentioned is connected at its lower end. Pivotally mounted upon one leg of the tower 24 at 52 is a lever 53 the inner end of which carries a collar'54 surrounding the sleeve 49 and to this arm 53 is erating member 55, passing a convenient point of access the tower. It will thus be when it is desired to render the wind wheel inoperative, the operator pulls upon the cable 55 drawing the sleeve'49 downwardly and actuating the connecting member 48 so as to pull the lever arm 41 and its collar against the tension of the spring 42, said collar through its connection with the collar 46 rotating the shaft 27 and raising the rudder 25 to the horizontal position indicated by Fig. 1. The wheel is thus turned outof the wind by the overbalancing action hereinbefore mentioned and the brake applied to prevent its rotation.

downwardly to at the base of Having thus described my invention, what I claimv as new is: V
