WINDMILL.
S'PECIFICATION forming part of LettersPatent No. 650,011, dated May 22, 1900. Application filed May 3,1899- Serial No. 715,419. (No model.)
To (tZZ whom it may concern:
Be itknown that I, CHARLES HENRY HEROD, pattern-maker, of the city of Brantford, in the county of Brant and Province of Ontario, Canada, have invented certain new and useful Improvements in Windmills, (for which I have obtained Canadian Letters Patent No. 63,467, dated July 17, 1899,) of which the following is a specification.
The object of my invention is to devise simple and effective means for governing a Windmill and for holding it out of the wind; and itconsists, essentially, in connecting the vane and the engine by tension-spring connections, means being provided whereby the relative positions of the lines of draft of the said connections may be shifted with regard to the pivot point or points of the engine and vane, so that the latter may be held in line by spring tension or similarly held out of line, substantially as hereinafter more specifically described and then definitely claimed.
Figure'l is a plan view of the upper portion of the windmill provided with my improvements, the engine being turned out of the wind. Fig. 2 is a similar view, partly broken away, the engine being shown in the wind. Fig. 3 is a side elevation of the upper portion of the windmill provided with my improvements with the engine in the wind. Figs. 4 and 5 are details illustrating alternative forms of spring connections to the vane.
In the drawings like letters of reference indicate corresponding parts in the different figures.
A is the turn-table support at the top of the windmill. table support revolves, preferably with roller or ball bearings, the ring B, to which the vane E is connected. Upon this ring revolves,- preferably with roller or ball bearings, the ring 0, to which the engine D is connected. As shown, the Vane E is forked and the lower branch of the fork connected to the ring B, while the upper branch is pivotally connected with the engine D above the center of the turn-table A. It will thus be seen that the engine and the vane are so supported upon the tower as to swing independently of one another. Upon the vane E is pivoted the equalizer F, which maybe either'a-levcr,
(See Fig. 3.) Upon this turn-- der tension will tend normally to keep the curved surface of the quadrant in contact with the fixed dog J secured to the bell-crank lever K, which is pivoted upon the engine below the quadrant H. One end of this lever is at the opposite side of the vane from the spring I and is connected by the link L I to the other end of the equalizer F. This link may be flexible, if desired, as shown at L in Fig. 4 and at L in Fig. 5, as it undergoes a tensional strain only. I If a pulley-equalizer is used, as shown in Fig. 5, at least a portion of the link must be flexible close to the pulley and wrapped around or otherwise secured to it. The spring is also preferably provided at its end with a flexible cord or chain wrapped around or otherwise secured to the pulley, the motion of which is preferably limited by a stop F.
J ournaled upon the engine is the vertical spindle M, upon which are secured pulleys or sprocket-Wheels c and d. Wrapped around the sprocket-wheel c is a sprocket-chain e, which has one end secured to the said sprocket-wheel c, and which chain passes over an idler-pulley f and thence down to the ground, where it may be fastened in anysuitable manner. Wrapped around the sprocketwheel (1 is a sprocket-chain 9, one end of which is connected to said wheel d and the other to the end of the bell-crank lever K. It is evident that by drawing upon the sprocketchain c and fastening it the endof the lever to which the chain g is attached and the engine may be drawn toward one another and held there or allowed to move apart'when the chain is released, so as to occupy either the position shown in Fig. 1 or that in Fig. 2.
When the chain e is drawn upon and the end of the lever K and the engine brought close together, the notch 71 in quadrant H is brought into engagement with the fixed dog J and the quadrant thus held from moving in either direction-until it is suitably released. When the parts'are in this position,-the ten sion of the spring I tends to maintain the engine in the position shown with regardto the vanethat is, with the wheel facing the wind.
In practice the wheel will be slightly in? clined toward the left of the drawings, so that extra-strong pufis of wind will tend to swing it in that direction, and thus enable it to spill the wind. This motion is resisted by the tension of the spring .I, which immediately 1'6...
turns the engineto its original position when the wind abates in force. :By releasing the chain ethe lever K will be allowed to swing. When'this lever swings, it lifts the dogJ out of engagement with the quadrant II. The tension of the spring I now causes the parts to assume-the position shown in Fig. 1.
Upon the'rin g Bis fixed a stop j, with which engages a stoplc 0n the ring 0. When the engine .and Vane are in the position shown in Fig; 1, thesestops are engaged with-one another, and thus prevent the engine swinging farther than is necessary to bring its wheel parallel'with the vane. A stopl may also beconnected to the ring B to prevent theengine when it is drawn into the wind being pulled past thepoint at which itsw-heel is at right angles to the vane, save for theslight inclination previously described.
It will be observed that the principle of my invention is substantially as follows: If three bodies-such as :the vane, the engine, and
thebelbcrank1everbe pivoted together s ubstantially at or near the same point and two" ofrthem, such as the lever and the engine, be connected by spring connections with opposite sides of the third, such as the vane, the
position of the two with regard to the third to :move the third body to one side or the other is resisted'by the spring connections. In other words, if three bodies be pivoted and con- -ne.cted as described and the first two have their relative positions toward one another: changed then the equilibrium of the system is-disturbed and the relative position of the two toward the third changes until .the spring tension isagain equal on the opposite sides of the third, In any position an attempt to swingthethird body to either side meets with a-spring resistance.
Anexamination of Figs. 1 and 2 will show that the lines of draft of the connections between the vane and the engineand lever are shifted from left to right when bringing the engine into the wind and from right to left when taking it out of the wind.
The object in holding the end of 'thelink close in toward the pivot-point of the vane by means of the quadrant H is that if the link were permitted to swing freely from its .pivot-point on the engine the swinging of the engine to the left by a strong blast. of wind .wouldgradually shift the line of draft of the spring I out from the pivot-point, giving it greater leverage, and the tendency of the engine .tofly back to its original position would be considerably reduced.
The object in using the equalizer is to en able one spring to take the place of two, though, of course,-two springs might be readily used, as shown in Fig. 4. I
N is a disk forming a portion of the-hub of the wheel. Aroundthis disk is a brake-band 0. One end of this band issecured to a stationary portion of the engine, as shown, and the other end pivoted to the short end of the lever P, which itself is journaled upon "a stationary portion of the engine. The longer end of the lever P is connected by the pivoted link Q with the lever K close to its pivot-point. From this it will be seenthat when the parts assume the positionshown in Fig. 1 the lever P is'drawn upon to tighten the brake-band about th'e'disk N and that this is one of the first efiects produced by releasing the sprocket-chaine. Atthe same time as soon as the lever is drawn upon to bring 'the engine into the wind one of the first effects is toshift the lever P and release by spring tension, or similarly held outofline, substantially as and for the purpose specified. 1
