SPECIFICATION forming part of Letters Patent No. 417,416, dated December 17, 1889.

Application filed July 26, 1889. Serial No. 318,777. (No model.)

To all whom it may concern: device, as will be hereinafter more fully Be it known that I, HENRY L. FERRIS, of stated.

a full, clear,'and exact description thereof, Neither the windmill, the pump, nor the reference being had to the accompanying connections of the rod 13 form any part of the drawings, and to the letters of reference present invention. These parts have not re marked thereon, which form a part of this been illustrated, as my invention is not to be specification. confined to any particular windmill.

The use of this frame-plate, while to throw the operating-wheel back into the preferred, is, however, not essential to the opwind automatically as the water is lowered eration of the regulating device, as the latter in the tank, and thus causing the pumping may obviously be supported directly upon of water to be resumed. the cross-beams A A.

Loosely mounted upon the shaft I) on the end adjacent to the flange 0 is a spool or sleeve 1), which carries a lug or arm (I.

D is a two-armed lever, pivoted at (l to the lug d, and having the end of its lower arm bifurcated, so that said arm mayencirele the said shaft Z).

D is a spring placed around the shaft Z) and interposed between the end of the loose sleeve D and the bifurcated arm of the lever D. One end of the sleeve rests against the face of the ratchetavheel C, as will be readily understood, and therefore the spring D tends constantly to press the bifurcated arm of the lever D outwardly or away from the said sleeve. The tendency is checked, except as hereinbelow stated, by the pull of the float A, which, when the water in the tank is exhausted, acts as a weight.

E is a lever pivoted at e to a suitable lug on the frame-plate B, (or on the cross-bar A,) and connected at its lower end with the cable or rod a. The upper end or arm 6 is bifurcated to surround the shaft 1), and presses against the bifurcated arm of the lever D. The weight of the float A thus tends to hold the lever D in theposition illustrated in Fig. 1, while the spring D exerts its power in the opposite direction.

D is a bracket-arm extending out from the sleeve D, it being integral therewith and with the arm (I. The gripping-lever arm F is pivoted atfto the end of the bracket-arm D The outer upturned end f of this arm F is attached to the cable, wire, or rod F, by pull.- ing on which the windmill is turned out of the wind, while the other and shorter arm f is bent upwardly, so that its bifurcated end f will engage the rounded end of (or a pin or stud on) the arm I). This lever F is provided with two raised lugs or projections f f, which constitute the clutch mechanism. The adjacent faces of these lugs f f" are substantially parallel, and are at such distance apart only as will admit the free passage between them of the flange c of the ratchet-wheel when the arm F is in its normal position, as shown in Figs. 1, 3, Jr, 5, and 7. \Yhen said lever is moved very slightly from the normal position, the position of the faces of the lugsf f is changed, so that they bear against the rim or flange c of the ratchet-wheel, one on the inside and one on the out-side, as shown. The greater the movement the greater the frictional bearing of these parts. Such movement is comm unicated to the lever F by the spring D G is a cable, wire, or rod engaging at one end the lower end of the lever E, whereby by pulling on said cable G the level-E may be moved by hand against the pressure of the spring D The operation of my device is as follows:

The parts being in the position illustrated in Figs. 1, 3, 4, 5, and '7, the windmill in the wind, and the )llIllp-l()(l ll moving up and down, and thereby, through the lever (1', rotating the ratchet-wheel, except when the pawl C is disengaged from the teeth of the ratchet-wheel, when a sufficient quantity of water has been pumped into the tank A, the float A" will have raised to'such a position as to cause a slackening of the cable a, whereupon, the pressure against the spring D through the lever (1 cable a", and lever E,being removed, the spring forces the bifurcated lower end of the arm D outwardly, and at the same time, through the other end arm of this lever 1), draws the cndf of the arm F downwardly. The lugs f" f now firmly engage the rim or flange 0, thus uniting the arm F to the ratchetwheel 0. As the ratchet-wheel is revolved by the continued reciprocating movement of pump-rod and the lever C, the wheel carries with it the lever F, until finally said lever is in the position shown in Figs. 2, t and 8. lVhen the water is being drawn out of the tank, the weighted float A descends, and thereby automatically throws the governing-wheel into the wind again by exerting pressure against the spring D thereby throwing the arm f up and loosening the grip of the clutches ff on the flange e. As will be readily understood, the cable F being thereby slackened, the operating-wheel promptly flies into the wind and at once begins work. It will thus readily be understood that my improved device regulates the action of the wind-wheel both when in the wind and when out of the wind. Should it be desired, however, to throw the mill into the wind for a few moments at a time-as, for example, long enough to pump a pail full of water-this may be accomplished by a downward pull upon the cable G. This cable G is trained over the pulley g, and is connected to the lower end of the lever E. The downward pull upon the cable G causes the upper arm of the lever E to press the lower end of the lever D toward and against the spring D raise the upper arm of the lever l) and the short arm of the gripping-lever F, and thereby loosen the grip of the lugs f" f on the flange c. The friction being thus released, the windmill swings into the wind, pulling the lever F up into its normal position. Upon releasing the tension on the cable G the spring D operates the levers D and F again, as heretofore explained, and the lugs f f again grip the flange c of the ratchet-wheel.

It is found that even when the mill is out of the wind the direction of the wind will suddenly change sufficiently to operate the mill for a short time. In such cases provision must be-made to prevent the continued rotation of the ratchet-wheel and the parts connected to it, lest these parts become strained, twisted, or broken. To obviate such trouble,

I place an arm II upon the sleeve D in such position that when the arm F has reached the position illustrated in Fig. 2 the end h of said arm will have engaged the under side of the pawl C and will have raised said pawl out of engagement with the ratch et-Wheel. It will be manifest that in this position any os-' cillation of the arm 0' will not cause any rotation of the ratchet-wheel.

W hat I claim, and desire to secure by Letters Patent, is as follows:

1. In combination-with the pump-rod of a windmill and a cable for drawing the mill out of the wind, a ratchet-wheel, a lever connected to the pump-rod andhaving a pawl to engage the ratchet-wheel, a clutch-lever connected to the windmill-cable and having clutches for engagement with the rim of said ratchet-wheel, and mechanism, substantially as described, for causing said clutchlever to frictionally engage the ratchet-wheel, substantially as described. I

2. The combination, with a pump-rod and a cable for drawing the mill out of the wind,

of a clutch-lever connected to said cable, a

ratchet-wheel provided with a flange, a lever connected to the pump-rod and having a pawl thereon for engagement with the ratchet-wheel, a pivoted lever, one arm of which engages the .said clutch-lever, and a 'spring in engagement with the other end of said pivoted lever, whereby by the pressure of said spring the clutch-lever is caused to frictionally engage the flange of the ratchetwheel, substantially as described.

3. The combination, with a pump-rod of a windmill and a cable for drawing the mill out of the wind, of a water-tank and a v weighted float therein connected to said cable, a pawl and ratchet-wheel connected to said pump-rod, and a clutch-lever connected to said cable and adapted to grip the said ratchet-wheel when the weight of the float is relieved by the raising of the water in the tank, substantially as described.
