JOHN H. KESTER, OF WINSTON, NORTH CAROLINA.

WINDLASS WATER-ELEVATOR.

$PEGIFIGATION forming part of Letters Patent No. 579,799, dated March 30, 1897.

Application filed August 31 1896.

To all whom it may concern.-

Be it known that I, JOHN H. KESTER, a citizen of the United States, and a resident of Winston, in the county of Forsyth and State of North Carolina, have invented certain new and useful Improvements in Windlass Water- Elevators; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to Windlass waterelevating apparatus, in which two alternately-operating buckets are employed, one of which rises as the other descends. As usually constructed these devices comprise a Windlass or drum, upon which the elevatingrope is wound, provided at each end with a bucket, and the Windlass provided with a crank, by turning which in one direction the drum is rotated, elevating one bucket and lowering the other, and then rotating the crank in the opposite direction, so as to reverse the operation. In such construction of elevating apparatus there is a great loss of time and labor in alternately reversing the movement of the crank; and the object of my invention is to provide an improved construction whereby the crank always turns in the same direction, mechanism being provided whereby the movement of the Windlass is automatically and alternately reversed when one of the buckets is raised to the top of the well, so as to lower the same and raise the other bucket.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

I11 the accompanying drawings, Figure 1 is a longitudinal sectional view of a Windlass water-elevating apparatus constructed in accordance with my invention. Fig. 2 is a central transverse section of the same. Fig. 3 is a longitudinal section on the line y y, Fig. 2. Fig. 4 is a similar view, the shifting arm and weighted lever being removed. Fig. 5 is a detail perspective view of the lever for Serial No. 601,527. (No model.)

operating the eccentric brake. Fig. 6 is a similar view of one of the pivoted arms and its disk which the buckets strike at the end of the upward stroke to shift the drum or Windlass. v

In the said drawings the reference-numeral 1 designates a housing at the upper end of a well, provided at the top with a casing 2, having a semicircular hinged top 3, which incloses the drum or Windlass and its gearing. This casing is provided with a sleeve 4, in which is journaled a shaft 5, the outer end of which is provided with a crank 6, while its inner end has fixed to it a wheel 7, which meshes with cogs 8 on the inner side of an annular flange 9 of a drum or Windlass 10, formed with a peripheral groove 12. This drum is provided with a hoisting-rope 13, having a bucket 14 at each end, one of which, however, is only shown, and said rope is so wound on the Windlass that as the latter is rotated one bucket will ascend and the other descend. The said Windlass is journaled on an arm projecting from a bracket 15, pivoted at its lower end to a stud-shaft 16, and the upper end of which is bifurcated, forming two upwardly-extending arms 17. Also pivoted on said stud-shaft is a lever 18, having a downwardly-extending arm pivoted to each end, provided at the lower end with a disk 19, having an aperture 20, through which the hoisting or elevating rope passes. Near one end said lever is provided with an upwardlyextending curved bracket 21, having a slot or recess 22 formed in the under side of its upper end.

The numeral 23 designates a stud secured to the casing 2, on the inner end of which is journaled a lever 24, provided at its upper end with a weight 25 and having a pin 26, which engages with said slot 22. The lower end of this lever is provided with an outwardly-extending pin 27, which lies between the arms 17 and is adapted to alternately strike the same as the lever 18 is operated, as hereinafter described. Journaled on a stud-shaft 28 at one side of the sleeve 4 is a pinion 29, which meshes with the cog-wheel 7, so as to turn therewith, but in the opposite direction. This pinion is also adapted to mesh with the cogged flange 9 of the Windlass when the latter is shifted, as hereinafter described, to throw the cog-wheel 7 out of engagement therewith, the diameter of the cogged flange being somewhat greater than the combined diameters of the cog-wheel and pinion, as seen in Fig. 1, so that when the cog-wheel is in engagement with the cogged flange the pinion will be out of engagement therewith.

The numerall4 designates one of the buckets, having a discharge-spout at the lower end, provided with a valve and pivoted valve-stem 31. Connected with the stem is a rod 32, which passes up through the top of the bucket and is adapted to strike the disk 19 as the bucket reaches the end of its upstroke and open the valve and allow the water to escape. Secured to the housing 1 in the interior thereof is apartition 34, having openings to allow the buckets to pass through. The edges of this partition are turned upwardly, as seen in Figs. 1 and 2, forming an annular water-passage 30, provided with a discharge-spout 37. The said partition is provided with a pivoted deflecting-plate 38 to prevent the water from one bucket splashing over into the opening of the other bucket and escaping back into the well.

Referring now to Fig. 1, the numeral 39 designates an eccentric on the hub 39 of the casing, upon which is journaled an eccentricstrap 40, provided with a brake-shoe 41. The face of the cog-wheel 7 is recessed, forming a flange 42, with which the brake-shoe engages. This brake-shoe will allow the cog-wheel to readily turn in one direction, yet will prevent backward movement of the same and the Windlass and thus hold the buckets at any height to which they may be raised. It sometimes happens that when the bucket has been elevated and the discharge-valve opened by the rod 32 coming in contact with the disk 19 it is desirable that all the water be not discharged from the bucket, and for this purpose I provide the following means for slightly lowering the bucket, so that the rod will be carried out of contact with the disk and the valve closed by the pressure of the water in the bucket: Referring to Figs. 1, 2, and 4, the numeral 43 designates a lever pivoted to the casing 2, having apin 45 at its inner end, which rests beneath the brake-shoe 41. By moving this lever the brake-shoe may be thrown up out of contact with the flange 42, allowing the cog-wheel and Windlass to turn backward through the weight of the bucket and the latter to fall a short distance, when the lever is released and the brake-shoe will again fall into contact with the flange and check the further downward movement of the bucket.

The operation is as follows: In Fig. 1 the bucket is shown as having reached the end of its upstroke, the escapevalve being opened and the water-discharging and cogged flange of the Windlass being thrown into engagement with the cog-wheel 7. After the water has been emptied from the bucket the cog-wheel is turned by means of the crank in the direction of the arrow, rotating the Windlass and lowering the said bucket and raising the other bucket, (not shown,) when the rod 32 of this latter bucket strikes the disk 19 at the left of this end, the lever 18 raising the same and throwing the curved arm or bracket to the right, which, engaging with the pin 26, throws the weighted lever 24 to the right and its lower end to the left, when the pin 27 will strike the arm 17 at the left, shifting the drum or Windlass. to the left and throwing the cogged flange out of engagement with the cog-wheel 7 and into engagement with the pinion 29, so that as the crank and cog-wheel continue their rotation the drum will be retated by the pinion in a reverse direction 7 and the said bucket lowered and the first bucket be again elevated. When this lastmentioned bucket again reaches the end of its upstroke, a reverse movement of the lever, curved arm, and weighted lever will take place to shift the drum or Windlass to the right, throwing the pinion out of mesh with the cogged flange and the cog-wheel again into engagement therewith.

Having thus fully described my invention, what I claim is- 1. I11 awater-elevating apparatus, the combination with the intermeshin g cog-wheel and pinion, of the rotatable cogged drum, the pivoted bifurcated arm to which said drum is journaled, thepivoted lever having a curved and slotted arm, the pivoted weighted lever having a pin engaging with said slotted arm and a pin adapted to engage with said bifurcated arm, and means substantially as described for operating said levers for throwing the cogged drum alternately into and out of engagement with said cog-wheel and pinion.

2. In a water-elevating apparatus the combination with the intermeshing cog-wheel and pinion, of the rotatable cogged drum, the pivoted bifurcated arm to which said drum is journaled, the pivoted lever having a curved and slotted arm, the downwardly-depending arms having apertured disks, the pivoted weighted lever provided with oppositely-extending pins, the elevating-rope passing around said drum and having a bucket at each end, the valve at the bottom of said buckets, the. valve-rod and the vertical rod connected therewith, substantially as described.

3. In a water-elevating apparatus of the character described, the combination with the casing having a curved opening or slot therein, the cog-wheel having an annular recess in one face, the intermeshing pinion, the eccentric-hub on the casing and the brake-shoe my own I have hereunto affixed my signature in presence of two Witnesses.
