IMPROVEMENT IN WATER-ELEVATORS.

Specilication forming part of Letters Patent No. 40,637, dated November 17, 1863.

To all whom it may concern:

Beit known that I, HIRAM NASH, of Pittsfield, in the county ot' Berkshire and State ot' Massachusetts, have invented certain new and useful Improvements in Apparatus for Drawing Water from Wells; and I do hereby declare that the following is afull and exact description thereof, reference being had to the accompanying drawings, making part of this specication.

Figure l is a plan of my improved machine, the cover of the curb being removed; Fig. 2. a central vertical section ofthe same Fig. 3, an elevation of the bucket, the cross-bar, the elevatingcord, and also the guides .i'or centering the bucket; Fig. 4, a view ot' the device for engaging the winch with the windlass; Fig. 5, a diagram exhibiting a side view ofthe lever connecting the pawl andY brake.

Like letters of reference indicate corresponding parts in all the igures.

My improved machine is ot' that class in which the bottom of the bucket is provided with anv automatic valve and spout for discharging the water into the spout. ot' the curb when at the proper position. A suitable curb, A, is provided, in which is mounted a windlass, B, as usual, having aratchet-wheel, C, into which catchesa pawl,D, and provided also with a winch, E, by which it is operated. The windlass is provided with two heads or disks, a af, Figs. l and 2, at suitable distance apart, leaving the central intermediate portion of smaller diameter, on which portion winds the elevating cord or chain F. This cord or chain is single, except at its lower end, which diverges into two branches, b b, Figs. l and 3, of suitable length to wind once or more .around the windlass, and attached to the cross-bar Gr, sustaining the bucket, by passing through eyes c o. The cross-bar is preferably iron and the eyes cast in. The cross-bar G, Figs. 1, 2, and 3, is a simple, plain bar, provided at each end with a block, e, whose upper surface is similarly beveled at ff, on opposite sides, in such a manner that it either bevel strikes the heads a a it will throw the bar outward into the angular position indicated in Fig. 2, and consequently, also, throw the bucket outward. The opposite side of the cross-bar has eyes or projections g g, of suitable length, to which are secured the bails h h, connecting the cross-bar and bucket. An arm, t', projects centrally from the bottom of the cross-bar, and this in turn is provided with a right-angled crosshead. lr, through holes in the opposite ends of' which respectively pass rods d df, Fig. 2, having knobs or equivalent, on their ends t) hold them in place, and connecting with valves H H, that cover, respectively, ports l l in the bottom of the bucket. Beneath the partsthe bucket is provided with a double spout, I l', running in opposite directions, and conveniently, though not necessarily,madeina single piece, with a centralpartition. At a suitable position, the sides of the curb, atright angles t0 that containing the spout, are respectively provided with guides K K, Figs. l, 2, and 3, made beveling at their bottom, and situated at such a distance apart as to admitthe bucket easily between them, but not allowing a great deal ot' extra space.

The operation of the arrangement above described is as follows turned, the single cord or chain F winds up till its branches b b strike. when, by its double bearing on the windlass, it turns the bucket either to' one side or the other, indifterently,

so that one end or the other of the double spout I 1 will come in proper position, relatively to the curb-spout, to discharge the water. The branches b b ot' the cord might not always strike the windlass in the middle of its winding portion, and consequently might throw the bucket on one side of the f center, and this difficulty is increased from the fact that the strain on the branches keeps them taut, so th at if the bucket should turn the wron g wa-y it might be considerably displaced. Any difficulty of this kind is obviated by the use of thc beveled guides K, for the bucket, striking between them, has no alternative but to rise centrally, while at the same time the branches of the cord hold it steady and keep it from turning. As soon as the cord is so far wound up as to bring the blocks e e of the cross-bar in contact with the heads a a of the windlass, the tendency is to throw the cross-bar outward in an angular position, as in Fig. 2, which action, of course, likewise throws the bucket outward sufliciently to bring the spout of the bucket in proximity with that of the curb. It is immaterial which side out the bucket comes up,"'as the bevels f f will perform the same office in either case, throwing the bucket outward, so

The windlass being as to discharge its water without loss. This action is essential in the use of a bucket with a double spout. When the cross-ba-r-is thrown out, as above described, the angular position of the arm t' is such as to raise the outer rod, d, and consequently its valve, H, while the other valve, H', remains closed. The arran gementof parts is especially adapted to the discharge of the water properly on either side of the bucket that may come outward, while it is shut oli' on the opposite side. This is accomplished by one end of the cross-head 7c being elevated while the other is depressed, thus acting on one rod while the otherI is left free. By the use of the double spout it matters not which side of the bucket may be presented to the side of the curb, as the discharge will be the same, the valve on the proper side opening and the other remaining closed. This arrangement is essential where but a single elevating-cord is employed, for the bucket will not always come up the same side outward. The pawl D is jointed atits rear end, asusual, so as to be raised or lowered, and at the proper position within it is connected, by an eye, m, or otherwise, to a lever, L, Figs. 1, 2, and 5, passing inward at right angles and resting on a fulrrum N, and having on its opposite side, situated over its shank, a brake, M, extending to the rear ofthe windlass, and suitably jointed, as represented at n. The position ofthe brake is over the head a', on which it bears to produce the brake-action. 1t is obvious that the action of this arrangement is automatic, the pawl being raised from the ratchetwheel through the medium of the lever, when the brake is pressed down so as to bear on the windlass, and vice versa, being brought linto engagement with the ratchet-wheelv when the brake is released. 'l hns the bucket is allowed to run back into the well when empty by merely pressing on the brake; and in being rais ed it is always securely retained, while at the same time-the brake is over-balanced by the weight of the pawl, so that it does not bear at all on the windlass, thus preventing wear to either part.

To keep the winch from turning back while the empty bucket is descending the well, I make it to turn freely and independently in the windlass-shaft, resting against a ratchetdisk, Q, Figs. I and 4, and rigid with the shaft, and l provide the winch with a hinged latch or catch, P, which, when down, and theV winch is turning forward, catches the ratchet-l teeth and operates the windlass, but when raised away from the ratchet-tecth allows the .windlass to turn back independently.

In order to permit the bucket to descend, it is only neiessary to reverse the winch sufiiciently to allow the latch to fall out of engagement with the ratchet-disk by its own weight, and then press with the other hand on the brake, thusreleasin g the pawl D.

I do .not claim, broadly, throwing the bucket outward by the action of the cross-bar, nor operating a valve in the bucket by the same action, as such an effect is accomplished in my patent of May 27, 1862; neither do I claim, broadly, adouble spout by itself; but

Wha-t I claim as my invention, and desire to secure by Letters Patent, is-

1. The cross-bar G, provided with blocks e c, or their equivalent, having` double bearings f f, when said cross-bar is used in combination with the heads c a' of the windlass, for throwing the bucket outward, in either' position it may come up, substantially as herein set forth. 4

2. In combination with the cross-bar thus arranged and provided with the armi and cross-head lc, the double rods d d' and valves H H', for adapting the discharge to either side ofthe bucket that may come outward, substantially as herein set forth.

, 3. The double spout I I', in combination` lwith the valves H H', situated, respectively,

over each spout and operated automatically in such a manner that while one allows the discharge of water at the proper position the other shuts it off, substantially as herein described.

4. The arrangement and combination ofthe cross-bar G, double ro ls d d', valves H H', and double spout l I', substantially as speciiicd.

5. In combination with a bucket provided with thedouble spout I I' and valves H H', the two branch cords or chains b b, connected with the single cord or chain F in such a manner that when the bucket is fully raised ene end or the other of said spout will come in coincidence with the curb-spout, substantially as herein set forth.

6. In combination with the bucket thus connected with the win'dlass, the guides K'K, for centering the bucket, vsubstantially as described.

7. The combination of the brake M, lever L, pawl D, ratchet-wheel G, and head a', or equivalent, of the windlass, whereby, when the brake is applied, the pawl is disengaged automatically, and vice versa, substantially as described.

8. The loose winch E, ratchet-disk Q, and pivoted latch 19, when used in combination with the windlass B and a bucket provided with the double spout I I' and valves H H', substantially as specified.

9. The arrangement of the brake M, lever L, pawl D, ratchet-,wheel O, winch E, ratchetdisk Q, and pivotcd latch p, substantially as herein described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
