WIND-WHEEL.

SPECIFICATION forming part of Letters Patent No. 446,783, dated February 1'7, 1891. Application fled September 19,1890.. Serial No. 365,487. y(No model.)

To @ZZ whom it may con/cern.-

Be it known that I, JOHN M. LOWE, a citizen of the United States, residing at Butler, in the county of De Kalb and State of Indiana, have invented a new and useful Vindmill, of which the following is a specication.

My invention relates to improvements in regulators for windmills, which regulator is simple, durable, and effective, and has no springs to Wear out or weaken; and it consists in certain features of novelty to be hereinafter described, and then pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation showing a windmill plant lfor pumping water, the derrick being shown in section, with my improved regulator attached. Fig. 2 is a side view of the regulator. Fig. 3 is a perspective View, looking toward the inner side of the ratchet-wheel, of the regulator.

1 represents the derrick having the side bars 2, to which are secured the supportingbars 3 3 of the regulator. The windmill is not shown; but I have shown the pump-rod 4 and the wire 5, which is adapted to throw the windmill in and out of gear.

6 is apump having pipe connection 7 with an elevated tank 8, said tank having within it a suitable float. (Not shown.) Said float is suspended from the lower end of a bellcrank lever 9 by means of the wire connection 10, said bell-crank being pivoted to a post 11, that is inclined or extends over the tank S. The upper end of the bell-crank lever 9 is attached to the upwardly-extending stem 14 of a T-lever 13 by means of a connectingwire 12. To the outer end of the head 15 of the T-lever is secured a pull-cord 16 and to the inner end of which lever is secured a connecting-wire 17.

The regulator consists of the following parts Extending upwardly from the supportingbars 3 3a are lugs or supports 18 18, connecting which is a stationary shaft 19, which constitutes a bearing for several parts of the regulator. Between the side bars 3 3 and at one end of shaft19 is a large ratchet-wheel 20, having teeth 21, which are presented toward a pawl 22 of a horizontal lever 23 in such a manner as to be engaged by said pawl when the lever is moved up and down. Said lever is fulcrurned onthe shaft 19, and said pawl is pivoted on a stud 24, projecting from one side of the lever, and retained thereon by a cotterkey 25, which passes'through the end of said stud. The outer end of the lever is provided with a series of holes 26, in either one of which (its a stud 27, projecting from one end of link 28, said link being retained in the opening to which it is applied by a cotter-key 29, passing through the end of its stud. The other end of said link is pivotally connected with the pump-rod 4, and as said link may swing back and forth on its pivot when the pumprod is reciprocated it will not in any manner interfere with the vertical movement of said rod. Pivoted on a stud 30, projecting from the bar 3a, is a detent or pawl 31, which engages the teeth'of the ratchet-wheel, and which is retained on said stud by a Cotter-key 32, passing through the end of the stud. There are at about equal distances apart on the ratchetwheel 2O and formed integral therewith a lug 33, projecting laterally on the inner side of the periphery of the wheel,a weighted portion 34 and a delay portion 35, consisting of a flange at one side of the circumference of the wheel, so as not to interrupt the circular series of ratchet-teeth.

36 is a box or sleeve adapted to4 slide upon the shaft 19, and which is provided at one end with an upwardly-extending falciformlever 37, and the other end of which is provided with a pair of circumferential flanges 38, forming between them a groove 39. The free end of the lever 37 is provided with a slot 40, to receive a stud 41, projecting from one end of a link 42, which is retained in.

either of said openings by means of a cotterkey 43, passing through one end of said stud. The other end of the link 42 is connected with the wire 5, so that the windmill may be thrown automatically into and out of gear.

The support 1S at one end of the shaft 19 is provided with upwardlyand inwardlyT extending paired ears 44, between which is pivoted intermediate of its ends the trip-lever 45, the inner end of which extends nearly to the ratchet-wheel. Projecting from the un- .Ico

der side of the lever t? is a projection t6,the lower end of which is received by the groove 3). The outer end of the link is provided with a. sliding weight 47, adjustable thereon by means of a set-screw iS. rl`he wire 17, which is connected at. its upper end with the T-lever 13, is secured to the outer end of the trip-lever 5 at 10.

The regulator being constructed as shown and described, its operation will be as follows: rlhe tank S being full of water and the windmill out of gear, the parts of the regulator will be in position shown in full lines in Fig. 3-that is, the lug at the side of the ratchetwheel will be at the bottom of the wheel in engagement with the lever 37, the dog or detent 3l will be in engagement with the middle tooth between the ends of the flange 35, and the paw 22 of the horizontal lever 23 will be in engagement with the flange or delay portion 35, so that the up-and-down movement of the lever E23 will not cause its pawl to act upon the ratchet-wheel. As the water lowers in th'e tank, the float (not shown) within it pulls the inner end of the T-lever 13 upwardly through the medium of the connections above described, thus lifting the outer end of the trip-leverst, which causes the box or sleeve 3G to move toward the support 1S, thus releasing the lever 37 from the lug 33 and permitting the windmill-wire 5 to pull the lever up straight and bringing the wind-mill into gear. As soon as the lever 37 is swung up the inner end of the trip-lever 45 will be in engagement with a stop 50, projecting from one side of the ratchet-wheel and the lever remains in engagement with the stop while the windmill is pumping waterin to the tank. During this timethc pawl 22 is out of engagement with the ratchet-teeth, it being in engagement or resting against the delay portion As the tank fills with water, the float is raised, thus causing slack in the wire 17 and permitting the lever :t5 to descend by reason of its weight i7, thus forcing the lever 37 over against the ratchet-wheel and freeing the stop 50 from the inner end of said trip-lever. The ratchet-wheel is then free to revolve, its weighted portion turning it until the pawl 22 of the lever 23 is brought into engagement with one of the ratchet wheels. As the ratchet-wheel continues to revolve, the lug 33 forces the lever 37 around and downwardly and pulls the windmill out of gear, as before. In operation the pawl 22 catches in the ratchet-wheel two teeth above the pawl or detent 31. The stroke of the lever 23 is adjustable, as shown, to accommodate itself to different strokes ot' the pump-rod.

The hand trip-wire 1G is in all cases attached to the outer end of the T-lever and hangs down within convenient reach, so that the windmill may be tripped by hand, if de sired.

Should the tank be below the derriek 1 and not removed therefrom, as shown in Fig. 1, a float would be attached to the lower end of wire 14.3, the parts necessary for the operation of the tank shown being of course dispensed with.

That I claim is- 1. In a regulator for windmills, the combination, with a ratchet-wheel provided with a portion of a flange on one side of its periphery, a shaft on which the wheel is mounted, and devices controlled by said wheel for automatically throwing the windmill out of' gear, of a pawl adapted to engage one of the ratchet-teeth when the wheel is at rest midway between the ends of said flange portion, a horizont-al lever fulcrumed on said shaft and adapted for connection at its outer end with the pump-rod, and a pawl pivoted to said lever and adapted to rest upon said flanged portion, substantially as and for the purpose set forth.
