To all whom it may concern:

Be it known that I, LUcIUs YOUREE RAN- DALL, a citizen of the United States, and a resident of Gaffney, in the county of Cherokee and State of South Carolina, haveinventcd an Improvement in Windlass Water-Elevaserves for inlet and outlet of water, it beingv operated for the latter purpose by aswinging spout which is raised as the filled bucket or receptacle reaches the limit of its rise.

1 have devised various im provements, which are hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of my water-elevator, a portion of the box or casing inclosing the discharge-spout being removed. Fig. 2 is a central vertical section of the apparatus. Fig.

Fig. 4 includes a longitudinal section of one of the buckets and plan and perspective views of different parts thereof disassociated. Fig. 5 is a perspective view of a cross-bar with which the buckets come in contact alternately as they are raised, and thereby raise the hinged spout. Fig. 6 is a perspective view of the parts of a bracket forming part of the frame of the apparatus. Fig. 7 is a perspective view of a base-plate forming part of the frame of the apparatus. Fig. 8 is a perspective view of one of the bearings of a rotary shaft. Fig. 9 is a perspective view of the braking and locking device for the driving-wheel. Fig. 10 is a plan view of the duplex discharge-spout. Fig. 11 is a perspective view illustrating the construction of a portion of the box or casing containing the pivoted duplex discharge-spout.

Referring in the first instance to Figs. 1 and 3, A indicates a rectangular and oblong box or casing, which is supported upon a horizontal base B and contains the duplex pivoted discharge-spout G, into which the buckets D discharge alternately as they are raised to the required position. A rope E is connected with each of the buckets and passes over idlers or large pulleys F, mounted rotatably upon a shaft at the top of the frame which is supported upon the box A, and thence around the grooved driving wheel or pulley Gr. It is ap- H. (See Fig. 7.)

' parent that by rotating the said wheel or pulley G by means of the crank g the rope E may be caused to travel in one direction or the other as required to raise one bucket D or the other. In other words, by means of the crank the pulley G is rotated first in one direction and then the other, and thus one bucket is lowered as the other is raised, and vice versa, and each time that a bucket is raised the hinged spout O is also raised from a vertical position, as shown in Fig. 1, to a position indicated by dotted lines in Fig. 2, the same being slightly inclined to a horizontal line, so that the water will discharge freely atthe end of the spout which projects through a hole in the box A.

I will now proceed to describe the details of construction and arrangement of parts.

Upon the top of the box or casing A is bolted a T-shaped base-plate H, (see Fig. 7.) and this serves for attachment and support of four vertical posts, as follows: Posts I are fitted in sockets ii in the base-plate H and their upper ends enter sockets in bearings 2', in which the horizontal shaft J is journaled. (See especially Fig. 3.) Upon this shaft the idlers F are mounted rotatably, as before indicated. The shaft K, (see Figs. 1 and 2,) upon which the driving-pulley G is clamped, has its bearings in a front supporting post or bracket L and in a rear bearing M, (see Fig. 8,) which is secured to a hollow or tubular post N, the foot of the latter being screwed into a socket it, formed in the center of the head of t the aforesaid base-plate H. The front post or bracket L (see Fig. 3) is bifurcated and its lower ends are secured detachably by means of screw-bolts to the slotted vertical ears 7L2, which are cast integrally with the base-plate The said bracketL is extended above the bearing of the crank-shaft K, and to such portion is pivoted abrake and locking device O. (See especially Figs. 2, 3, and 9.) The free end of this device is curved downward and made V-shaped, whereby it is adapted to fit in the acute-angle groove of the driving wheel or pulley G. It is apparent that since the radius of the device O is shorter than that of the pulley G it will serve to lock or bind by friction with the latter when thrown either to the right or left. For the purpose of convenience of manipulation it is provided with a lateral handle 0. It will be noted that the form of the groove in the wheel Gr also causes it to bite the rope E, so that the latter is caused to travel with the wheel without slipping. The locking device may be l site receiver 0 The bottom of each of these held manually in vertical position, so as to be disengaged from the periphery of the pulley while the latter is being rotated, or it may be supported in such position by any suitable means that allow it to yield readily when requiredfor operation.

For the purpose of operatively connecting the buckets D and the spout C, so that the latter will be raised whenever a filled bucket has been elevated into the upper portion of the box or casing A, I provide the following means: A bent rod or gooseneck Q passes down through the hollow post N, and to its lower end within the box A is attached the cross-bar R. (See Fig. 5.) its middle portion a hub 0', through which the said rod .Q passes, and the same-is in practice provided with a clamp-screw for securing firmly to the rod. vided at each end with a perforated boss 1", and

through these bosses the end portions of the rope E pass. The required connection between the rod Q and the duplex spout C is effected by means of a bar or rod S, whose ends are jointed to clamps s and 8, attached, respectively, to the rod and to a short rearward and central projection or pin'c of the trough. (See Fig. 10.) In other words, the devices 8 s are two-part clamps secured together by screw-bolts and maintaining their hold by friction with the rod Q and pin 0. The weight of the gooseneck rod Q and the discharge-spout and the connection S is counterbalanced by means of a weight T, attached to a rope or cord U, that passes over an idler-pulley V and is secured to the rod, as shown plainly in Figs. 1 and 2. The said pulley V-is provided with gudgeons which support it in a bracket W, (see also Fig. 6,) the latter being arranged horizontally and supported by attachment to the hollow post N and the cross-shaft J that is to say, the bracket is provided at its inner end with a halfbox corresponding to another bracket W, whose bifurcations or branches to are provided with boxes for attachment to the said shaft J. Screw-bolts serve to secure the two brackets W and W together and to clamp them tightly upon the head of the hollow post N, as will be readily understood. The downwardly bent end of the gooseneck rod Q passes between the arms of the bracket W.

As shown in Fig. 10, the duplex dischargespout C is provided with gudgeons c at a point near its discharge end 0, and these gudgeons are provided with bearings in a plate or bracket 0 (see Fig. 2,) attached to the inner side of the box or casing A. In rear of the pivotal point the spoutdivides into two branches each of which is so constructed and arranged that it will receive the discharge of one of the buckets, the right-hand bucket of course discharging into the right-hand pocket or receptacle and the left-hand bucket into the oppo- This bar has at The bar R is also propockets or receivers 0 is provided with a series of vertical pins 0*. Each bucket is provided with a combined admission and discharge valve cZ, as shown in Fig. 4. The valve is of disk form and normally covers and closes an opening in the bottom of a bucket, and it has a certain vertical play which permits water to enter or discharge when the valve is To limit the rise of the valve d, 1 provide a guard or keeper (Z which has a disk having a central opening to receive the upper stem d of the valve and also with three downwardly-bent lugs or arms d, by which it is secured to the bottom of the lower head (Z5 of the bucket by means of rods d, that extend also through the upper head 6Z7 of the bucket, and thus hold all the parts together. It will be noticed that the cylindrical sheet-metal body of the bucket enters a circular groove (Z in both heads (Z and (Z and that the rods (Z serve to hold the two heads tightly in position, so that a water-tight joint is formed.

The rope'E passes through an opening in the upper head 6 of the bucket and is duly secured thereto by means of a knot, as shown in Fig. 4.

As illustrated in Figs. 2 and 8, the front side of the box or casing A is provided with a woven-wire guard. a, which covers the slot in which the outer end of the discharge-spout C works. This guard allows free discharge of water through it While preventing the entrance of insects. Directly above the guard is a door a, which extends completely across the box or casing and is hinged so that it may be opened for access to or inspection of the buckets, spout, and connecting devices when occasion requires. As illustrated in Fig. 11, the box or casing is formed by means of cross boards or planks, which fit in rabbets formed in corner-posts (6 The operation of the apparatus as a whole may be briefly indicated as follows: As shown in Fig. 1, one of the two buckets to which the rope is attached has been raised into contact with the cross-bar R, which is secured to the lifting-rod Q. If now the bucket be raised farther, the spout (I will begin to rise also, since the rod Q will be forced upward by the bucket acting against the crossbar R, and the weight T will descend correspondingly. The upward movement of the bucket and the rise of the spout C are illustrated in Fig. 2, the weight T being shown also at a lower point than in Fig. 1 and the rodQliftedcorrespondingly. Ifnow,through rotation of the driving-wheel Gr, the bucket be raised farther or to the position indicated by dotted lines, Fig. 2, the spout will be carried upward far enough to cause the pin d, that projects from the disk valve of the bucket, to strike in the bottom of the left-hand pocket or receiver of the spout, and thereby automatically open the valve d and allow escape of the contents of the bucket into the spout and discharge of the same through the wireguard a. lt will be understood that when the filled bucket has been raised, as described, the crank g may be released, since the device 0 will automatically lock the wheel G and hold the bucket suspended while discharging. While the filled bucket is discharging, the other or empty bucket has descended into the water and has filled. -Then upon rotating the driving-wheel G in the opposite direction the filled bucket is raised and the empty bucket lowered simultaneously, it being apparent that as the empty bucket descends the spout C will be lowered to its original position indicated in Fig. 1. Thus the operation may be continued indefinitely by rotating the driving wheel G first in one direction and then in the other, it being locked by the device 0 each time a bucket is raised to the height required to effect discharge and the spout C being alternately raised and lowered to efiect automatic discharge of the contents of a bucket, as described.

It will be noted that the raised and chambered portion of the base-piece H receives the bar R, Figs. 2 and 5, when a bucket rises and the top of the latter is drawn against the top of the box or casing A, whereby the bucket is held firm and steady in position'at the time of contact with the spout and discharge of its contents. 7

The position or arrangement of the idlers F relative to the driving-wheel G is important. Considerable difiiculty has been experienced in this class of water-elevators in consequence of the wet rope freezing, so that it slides in the groove of the driving-wheel instead of engaging it firmly. I have avoided this by placing the idlers F far enough above the driver G to allow the rope to become free of water to such a degree that it will not slide on wheel G.

Experience has demonstrated that when the bottom of the spout-pockets c are left smooth the water delivered from the buckets is liable 'to overflow or run over the edge of the spout,

and I have therefore provided pins or projections 0 which serve to hinder the velocity of the water, and thus avoid the above result.

What I claim is l. The combination, with a suspending and hoisting rope, and means for causing the same to travel in either direction, of two buckets atbalanced rod adapted to slide vertically in suitable bearings and arranged between the bights of the rope so that the buckets work on opposite sides thereof, the rod having lateral projections with which the buckets come alternately in contact when raised. and a second rod connecting the first-named rod with the spout at a point intermediate of the two pockets therein, whereby the spout is raised by the said rod when a bucket rises and lifts the rod, as shown and described.

2. The combination of a bucket having an automatic discharge-valve, and means for suspending and hoisting the same, a rod adapted to slide vertically and having a lateral projection with which the bucket comes in conand a cross-bar attached thereto and arranged for contact with either bucket as it rises, a counterbalance for said rod and its attachments, and a discharge-spout and means for connecting it with the said rod, substantially as described.

4. The combination of two buckets, a rope whose ends are connected therewith,means for.

causing the rope to travel in either direction for raising and lowering the respective buckets alternately. a pivoted discharge-spout having two pockets or receiving portions adapted to coact with the respective buckets to receive the contents of the same, and means for operatively connecting the spout with the buckets whereby it will be raised as either bucket approaches the upward limit of its movement, the said means comprising a vertically-slidable rod, a guide for the same, a cross-bar extending horizontally from the rod for engagement with either bucket as it rises, and a connecting-bar which is pivotally attached to the spout and said rod at its respective ends, substantially as described.

5. The combination with buckets and a rope connecting the same, idlers over which the rope passes, and a driving-pulley located below the idlers and equidistant therefrom so that the rope passes thereto from the idlers, means for rotating the said driving-pulley, and an automatic lock for the same consisting of an arm which is pivoted at a fixed point located eccentric to the pulley-axis, and whose head is curved and V shape to adapt it to fit in the groove of the pulley as shown and described.

6. The combination, with buckets, and a rope connecting them, of a hinged spout and a gooseneck rod connected with said spout for raising it when the said rod is lifted, means for causing the rope to travel in either direction and a counterbalance for said rod comprising a weight, a rope connecting it with the gooseneck and an idler-pulley over which! the rope travels, substantially as described.

7. The combinationv of two buckets, a suspending and hoisting rope connected therewithand pulleys on which said rope is adapted to travel in either direction, a vertically-- slidable rod, and a cross-bar secured thereto and extended laterally, its ends being provided with perforated bosses through which the said rope passes, a pivoted spout and means connecting it with-the said rod in the manner described.
