WATER ELEVATING AND DELIVERING APPARATUS.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed March 13, 1906. Serial No. 305,835.

To aZZ whom it may concern:

Be it known that I, EDWARD D. CoUoH, a citizen of the United States of America, residing at Scotts Crossroads, in the county of Mecklenburg and State of Virginia, have invented new and useful Improvements in Water Elevating and Delivering Apparatus, of which the following is a specification.

This invention relates to water elevating and delivering apparatus, the object of the invention being to provide a bucket-hoisting a paratus for wells, employing in connection tl ierewith a delivery-trough and novel means whereby the same may be conveniently shifted to position beneath either bucket for de- I hvering the water discharged therefrom.

Still another object is the production of improved means for controlling the action of the Windlass, so as to simplify and reduce to a material extent the attendant labor in hoisting and lowering the buckets.

In the accompanying drawings, Fi ure 1 is a vertical longitudinal section of an elevating and delivering apparatus embodying my invention and as used for elevating water from a well, one of the buckets being shown in discharging position. Fig. 2 is a vertical transverse-section of the same. Fig. 3 is a detail section through the Windlass-locking mechanism. Fig. 4 is a section on the line 4 4 of Fig. 2, showing the means for operating the shifting delivery-trough.

Referring to the drawings, the numeral 1 designates a well-tube, upon which is arranged a curb or casing 2, which closes the mouth thereof, the said curb or casing being provided in its top with openings 3 and 4 for the passage of the stretches 5 and 6 of the hoist' g rope or cable 7. The cable 7 is supported and operated by a Windlass comprising a hoisting-pulley 8, around which it passes, said pulley being keyed to a shaft 9, journaled in bearings 10 upon supports 11, projecting upwardly from the top of the housing, the shaft having a projecting angular end 12 for the rece tion of an operating crank-handle. A shield 13 is suitably secured to the support 11 and is arranged to inclose and protect the Windlass mechanism.

Each stretch of the hoisting rope or cable 7 is designed to support a bucket 14, provided at its upper end with a cross-piece 15, to which the end of the cable is attached in any preferred manner. The bottom wall of the bucket is formed with a discharge-port 16,

. adapted to be closed by an upwardly-opening valve 17. The valve is arranged to move within a guide-yoke 18, secured to the bottom of the bucket, and is attached to the lower end of a stem 19, which stem is slidably fitted at its ends in guide-openings in the cross-piece 15 and yoke 18 and has its upper end projecting beyond the cross-piece and suitably bent or shaped to form an operatinghandle 20. When the bucket is in elevated position, the handle 20 projects through the opening 3 or 4, as the case may be, so that it may be grasped and an upward pull exerted by the operator to lift the valve to allow the water to discharge through the port 16.

Upon'the descent of each bucket within the well the valve 17 is forced upwardly by the pressure of the water under the weight of the bucket, and upon the upward movement of the bucket the valve is closed by the weight of the water within the bucket and held closed to retain the water until manually operated in the manner described.

Fixed to the Windlass-shaft 9 alongside the pulley 8 is a ratchet-wheel21, provided with teeth or notches 22, having straight or square side walls or shoulders and curved or rounded outer edges 23. A dog 24 is arranged to cooperate with said ratchet-Wheel and comprises a bar centrally pivoted upon a bolt 25, passing through ears 26, formed on one of the bearings 10. The inner or locking arm of the dog is properly shaped to engage the teeth or notches 22 and is formed with a curved recess 27 in its lower edge to receive and ride upon the curved surfaces 23 of the teeth. The other end of the dog projects outwardly through a slot in the shield 13 to form an operating handle or portion 28, whereby it may be adjusted into and out of locking engagement with the ratchet-wheel by the operator. It will be understood, of course, that the shaft 9 is turned in one direction or the other to lower one of the buckets and raise the com panion bucket and 'that in this operation after a crank is applied to the rectangular end 12 of the shaft 9 the dog is tilted to release position, and as the ratchet-wheel 21 turns with the shaft the curved edge of the pawl will ride upon the curved shoulders 23 of the ratchet-teeth and upon the cessation of movement of the shaft will automatically drop into engagement with one of the teeth or notches and lock the Windlass against movement.

A delivery-trough 29 is arranged within the curb to occupy a position immediately IIO ' ed to be shifted into alinement with either of below the elevated buckets. This trough comprises a bottom wall 30, side walls 31, and a rear end wall 32, the front end of the bucket being open for the discharge of the water. As shown, the front end of the trough projects exteriorly through and is slidable in a longitudinal opening 33, formed in one of the side walls of the casing, while the bottom wall 30 thereof is extended in rear of the wall 32 to form a projection 34, arranged to travel in a guideway formed by a pair of guide-r ails 3 5, extending longitudinally alongthe inner surface of the other side wall. The trough is normally supported in an inclined position and is provided with a crosspiece 36, forming a stop to engage a stop rib or bar 37, arranged below the opening 33 to hold the troughfrom outward movement and to properly guide it as it is shifted. The trough is thus slidably mounted and is adaptthe openings 3 or 4 to come below an elevated bucket on either the stretch. 5 or the stretch 6 of the hoisting-cable 7, so that upon opening the valve 17 the water will discharge from the bucket into the trough and be delivered by the latter to the exterior.

Secured to the side Walls of the trough are bracket-pieces 38, which support a guide-rod 39. An operating-lever 40 is provided at its lower end with a shifting-plate 41, having an elongated opening 42 for the passage of the rod 39, whereby the lever is slidably engaged with said rod. The upper end of the lever extends through the top of the curb and is mounted to rock or oscillate in a slotted fulcrum-plate 43 whereby upon swinging the upper end of the lever in one direction or the other the shifting-blade 41 may be caused to engage one or the other of the side walls of the delivery-trough and to shift said trough to come below either bucket upon the elevation of the latter to effect the discharge of the water therefrom.

It will be apparent that by the construction described the necessity of handling and dumping the buckets in the usual way is avoided and greater ease and convenience afforded in discharging the water elevated from the well.

Having thus described the invention, what is claimed as new is 1. In a water elevating and delivering apparatus, a well, a curb or casing provided with guides, a pair of valved buckets, hoisting means upon the casing for alternately and simultaneously raising and lowering said buckets, atrough shiftable horizontally in the guides to a position beneath either bucket when the latter is elevated, and a 1 lever fulcrumed on the casing and operatively connected with the trough, whereby the latter may be shifted independently of the hoisting means.

2. In a water elevating and delivering apparatus, a well, a curb or casing provided with guides, valved buckets, means mounted upon the curb or casing for raising and lowering the buckets, a delivery-trough slidably mounted in said guides to be shifted beneath either of the buckets upon the elevation of the latter to delivery position, a transverse rod upon the bucket, and an operating-lever fulcrumed upon the curb and having a trough-shifting portion loosely engaging said rod and adapted to be shifted into engagement with the sides of the trough to adjust the latter in either direction.

3. I11 a water elevating and delivering apparatus, a well, a curb or casing provided with guides and having an opening at one side, valved buckets, means mounted upon the curb or casing for raising and lowering the buckets, a delivery trough slidably mounted in said guides and projecting at its discharge end through said opening, said. trough having a bottom extension engaging one of the guides, and a pivoted lever for shifting the trough.

4. In a water elevating and delivering apparatus, a hoisting-rope, an operating-windlass therefor, a ratchet-wheel upon the windlass-shaft provided with notches or teeth having outer curved shoulders, and a gravity-dog having a portion to engage the teeth, said portion being formed with a recessed face to ride upon said curved shoulcers.

5. In a water elevating and delivering apparatus, a well, a curb or casing provided with guides, a pair of valved buckets, hoisting means supported by the casing for alternately and simultaneously raising and lowering said buckets, a delivery-trough slidably mounted in said guides to be shifted beneath either of the buckets upon the elevation thereof, said trough being provided with a transverse rod extending between the sides thereof, and an operating-lever fulcrumed on the casing and having a slotted end engaging said rod, and a bearing portion to engage the sides of the trough, whereby the latter may be shifted upon the reverse swinging movements of said lever.

In testimony whereof I affix my signature in presence of two witnesses.
