SPECIFICATION forming part of Letters Patent No. 235,594, dated December 14, 1880.

(No model.)

To all whom @t may concern:

Be it known that I, JOHN G. Voonnis, a citizen ot the United States, residing at Englewood, county of Bergen, and State ot'New Jersey, have invented certain new and usef'ul Improvements inWater-Elevators and I do hereby declare that the following is a full, clear, and exact description thereof, reference being to the accompanying drawings, and to the letters of reference vmarked thereon, Y making a part of this speciiication.

This invention relates to that class of waterelevators having two buckets, one of which is lowered as the other is drawn up, and vice. versa, the rotation of the windlass being reversed for the elevation of each bucket.

It consists, first, in combining with the windlass two rubber balls playing in ways inclined against its periphery on each side thereof, and operating to prevent its rotation by wedging in against it, and in applying levers to lift said balls, these levers bein g actuated by an intermediate centrally-pivoted lever extending from one to the other, and so arranged that the elevation of either end thereof will serve to throw up the corresponding lifting-lever and raise the ball at that end clear of the windlass, while the consequent depression of the opposite end of the rocking lever will permit the liftinglever at that end to drop by its gravity away from its ball and leave the latter free to engage the windlass. Each end of the intermediate rocking lever is struck and thrown up by the tilting of the bucket on that side of the well, so that the tilting of either bucket operates to Withdraw from contact with the windlass the ball which checked and prevented its return during its elevation, and simultaneously operates to drop the opposite ball into position to prevent a return of the windlass while the other bucket is being drawn up, the object of this part of my invention being to provide a simple windlass-stop which shall operate automatically and with certainty to prevent either bucket when full from dropping back into the well, if at any point in its ascent the crank of the windlass be left free.

It consists, second, in forming on the side of the discharging trough or spout into which the contents of the bucket are poured when it is 4automatically tilteda-notch or open recess, to

permit the rope of the bucket on the side next to said trough to drop vertically from the windlass when the bucket reaches the bottom of the well without increasing the width of the wellcurb for this purpose, and in providing a cover for said notch to prevent the water discharged from the bucket when tilted from dropping through the notch, said cover beingl automati-` cally lifted by the dropping ofthe tilting-bail, and closed by its own gravity when the bail is lifted by the bucket.

It consists, third,in combining with the rocking lever actuating the check-balls an indicator or pointer revolved by the tipping of said lever, so as to indicate invariably the direction in which ythe windlass is free to turn to draw up a bucket of water.

In the accompanying drawings, Figure 1 is `a vertical section taken through the well-curb journals revolve upon friction-rollers, C O, the' well-buckets, which are attached to the windlass by ropes winding thereon from its opposite ends in opposite directions, so that as the windlass is revolved in either direction one rope shall wind thereon and the other unwind. Hence when the windlass is turned to elevate one bucket it operates to lower the other bucket, the movement of the windlass being reversed to elevate the one or the other bucket.

rlhe size of the rope is so adjusted in proportion to the depth of the well and length of the windlass that in raising the buckets the rope, in windin g upon the windlass, shall reach the middle thereof j ust as the bucket has reached its tilting-point. (See Fig. 2.) Hence the two buckets are both brought nearly to the same point in the center of the well-curb to be tilted.

W W are weights, pivoted to depend from the ears of each bucket, to facilitate the tipping thereof when they strike the water.

IOO

D is a discharge trough and spout, placed within the curb against one side thereof at right angles to the axis of the wi'ndlass.

E is a wire tilting-bail, pivoted to the inner side of the trough against the curb, to swing out therefrom nearly to the center ot' the well.

a a are lugs projecting from the rim of each bucket, which, when the buckets are elevated into line with the tilting-bail E, are engaged thereby, so that as the bucket is drawn higher it is tipped over by the bail and its contents discharged into the trough D.

F (see Fig. 4) is a notch formed in the side of the trough D, deep enough and at the proper point to permit the rope carrying the bucket next to said trough to maintain its proper vertical position when the bucket is lowered to the bottom of the well.

To prevent a loss of water through said notch a tilting cover, G, Fig. 2, is placed thereon, its inner end being hinged to the upper inner edge of the recessv and left to project inwardly beyond the inner side of the notch far enough to be engaged by a projection, b, Fig. 2, from an inward bend, e, formed in the tilting-bail. This projecting end of the cover G serves as a lever for the cover, so that when the tilting-bail drops thereon, after being disengaged from the bucket, it will operate to throw up the cover and leave the notch Open, (see dotted lines, Fig. 2,) but when the bail is lifted by the bucket and its weight removed from the cover the cover will drop and close of its own weight. Hence when the bucket is elevated and tipped by the bail to discharge its contents the cover will fall over the notch and close it, as shown by positive lines in Fig. 2.

H H are elastic balls, playing in curved ways d d, so inclined toward the rim of the windlass that the balls shall, of their own gravity, roll down into the angle formed between the rim and the bottom of each way. (See dotted lines, Fig. l.) The bottom of each inclined way d is slotted to admit of the introduction ofone end of a bent or forked lever, K, pivoted at its bend or the juncture of its arms to a plate, L, to which the ways (l d are also secured. This plate is extended to reach from side to side of the curb, so as to support the ways d d and forked levers K K on both sides of the windlass. A long lever, M, is pivoted centrally to the lower side of the plate L, midway between the forked levers K K, so that each end thereof shall, when elevated,

. strike the lower arm of the lever K on that the lever K thus drops from the ball the ballwll roll against the rim of the windlass, (see dotted lines, Fig. 1;) and if the windlass be now turned toward it,vit will wedge into the angle between the rim of the windlass and the bottom of the inclined way, and thus lock andA arrest its movement.

A spring, i, Fig. 2, is coiled about the pivotpin of the lever M, between theinner lside of said lever and the plate L, and the lever is secured upon said pin by means of a nut and washer. Hence by an adjustment of the nut the pressure ot' the spring is brought to bear against the lever to prevent its free oscillation.

The position ot' the tilting-bail E with reference to thel rocking-lever M is so adjusted that the bottom of each bucket. when it is tilted, will strike the end ot' the lever on that side and throw it up. This upliftcd end of the lever M, actuating the forked lever K, will withdraw the elastic check-ball from that side of the windlass, leaving it free to revolve in that direction to admit of lowering the emptied bucket back into the well. At the same time the depression of the opposite arm of the lever M will allow the forked lever K on that side to drop of its own weight away from the elastic ball which it has upheld, and the ball, left free to roll down in its inclined way, will fall against the rim of the windlass and automatically prevent its rotation in that direction, so that if the crank beat any time released while the full bucket is being elevated this ball will hold and prevent a return of the windlass under the iniiuence ot' the weight of said bucket.

R R are light rods extending upward from each end of the rocking lever M, and which are brought together centrally at a point near the top of the cover of the well-curb, and made to terminate in a single pin, c. This pin passes into a slot cut lengthwise in a horizontal arm or crank, T, projecting from the lower end of a vertical rod, S, which, extending up above the well-cover, revolves in suitable bearings and terminates in a pointer, V. The crank-arm T pla-ys over a V-shaped horizontal bracket, j', (see Fig. 3,) whose apex is placed to project in line with the indicator-rod S.

The bracket serves as a guide for the pin c, so`

as to throw it out far enough in its lateral reciprocating movements under the iniuence of the oscillation ofthe lever M to carry over the crank-arm T.

In the drawings, Fig. 5, an equivalent device for producing a reverse rotary movement of the rod S and index-pointer V by means of the vibration or lateral reciprocating movement of the rods R R is illustrated. The upper ends of said rods, after being united, are made to separate and branch out into arms h h on either side of a drum, g, placed upon the rotating rod S, and cords jj are extended from each arm 7L to opposite sides of the drum, so that the outward movement of the one arm will rotate the drum in that direction, and thus reverse the position of the indicator V upon the rod which carries the drum.

By this means the position of the lever M IOO IOS

governing; that ot' the check-balls is indicated by the pointer V, which is thus made to turn toward the elevated end of said lever and point in the direction in which the windlass is left free to turn by the. withdrawal of the check-ball on that side thereof.

Iconternplate, as an equivalentfor the forked or bent levers K Keniployed to lift the checkballs H H, the use of straight rods working in suit-able guides and extending` upward in a proper direction from the respective ends of the rocking-lever M, so as to come into contact with the balls, each rod being so adjusted that it will operate, when pushed up by the elevation oi' its end oi the lever M, to raise the check-balls, on that side away from the windlass.

I do not claim, broadly, the use oi' a rocking lever, M, actuated by the well-buckets, for the purpose of releasing stops arranged to check the rotation of the Windlass from which the buckets are suspended; but

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a well-Windlass, B, well-buckets C, and rocking lever M, of inclined ways d and elastic balls H, and of levers K, actuated by the lever M to lift said balls H, substantially as and for the purpose herein set forth.

2. The combination, with the Well-curb A, the rocking-lever M, the revolving; indicator rod S, and a crank or drumupon said rod, of rods R R, extending upward from the ends ot' said lever to engage and actuate said crank or druin, substantially as and for the purpose herein set forth.

3. The combination, with the dischargetrough D, provided with a notch7 F, in its side, of a cover, Gr, and tilting-bail E, substantially as and for the purpose herein set forth.

In testimony whereof I have signed myname to this speeitication in the presence of two subscribing witnesses.
