IMPROVEMENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. 118,658, dated August 29, 1871.

To all whom it may concern:

Be it known that I, WILLIAM P. WENTwoRTH, of Seneca Falls, in the county of Seneca and in the State of NewYork, have invented certain new and useful Improvements in Tater-Elevators, and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the aceompanyin g drawing and to the letters of reference marked thereon, in which drawing- Figure 1 represents my improvement in posi-l tion for use upon awell-curb; Fig. 2, a detached top-plan view of my device g and Figs. 3 and 4, elevations of the same from the inside and outside, respectively.

Like letters represent similar parts in each gure.

The object of my improvement is the construction of an elevator' to be used over an openv well for the raising and lowering of the water-bucket, which shall have the advantages of simplicity, cheapness, and durability, by which, in operation, the bucket can be raised readily; in which there is no danger of the crank flying back or striking the person who is turning it; and having connected with it a brake for the purpose of lowering the bucket gently into the water; and the invention consists principally in combining with the chain-shaft and a ratchet-wheel secured thereon a crank pvoted upon said shaft and provided with a hooked pawl, which remains pendent when said crank hangs downward, and follows and engages with said ratchet when said crank is tiuned forward, substantially as and for the purpose hereinafter specied. It consists, further, in combining with the above-named devices a ratehetwheel, pawl, and brake, substantially as and for the purpose hereinafter shown.

In the drawing, A represents the water-elevator upon the well-curb, having a main shaft, B, suitably journaled in frames G over the center of the well, and a wheel upon the center of the shaft, which carries the chain to which the water-bucket is attached, all of which parts, except the shaft, are mentioned, in order to describe more fully the location, generalv arrangement, and method of operation of the device which is the proper subject of this application, and for no other purpose. Upon one of the ends of the shaft B, outside of one of the frames C, the

crank D, provided with a handle, c, upon the outside, and a seat, b, upon the-inside, and cast in one piece, is loosely pivoted, so that whenever the hand is removed from it it hangs by its own weight in a vertical position. Upon the seat b the ratchet E, provided with a claw, c, is pivoted, which claw in one direction of the turning of the crank engages with the faces of the teeth e of the ratchet-wheel F, which is secured upon said shaft. This ratchet-wheel is provided with a thimble, f, cast in one piece with it, for the purpose of giving increased strength, support, and stability to said wheel, and to bring its teeth outside of the frame G, and in a convenient position for the engagement of the ratchet. Upon the inside of the frame the ratchet-wheel G, provided with teeth g,is secured upon the shaft, having a body or friction-surface, L, less in diameter than the toothed portion of said weeel, against which frictionsmface the curved portion 'i ofthe brake H, pivoted upon said frame, passes, said curved portion being furnished with a proper shoe, j, and the handle of said brake being held up from falling by means of the strap I secured upon said frame. A pawl, J, pivoted also upon said frame, and provided with a vertical wing, It, which holds it correctly in position, engages with the teeth g of said ratchet-wheel, and prevents the same from turning.

In the operation of my device, by turning the crank in one direction the ratchet E engages with its ratchet-wheel and causes the shaft to turn, which raises the water-bucket; a-t the same time the pawl J, engaging with its proper ratchet-wheel, holds the bucket from falling back. WVhen the hand is removed from the crank, both it and its ratchet immediately fall by their own ,weight into a vertical position. IVhen it is de- 1. In combination with the shaft B and ratchbrake H, substantially a-s and for the purpose et-Whee F, the pivoted crank D, provided with shown. the hooked paWl E, which remains pendent when In testimony that I claim the foregoing I have said crank hangs downward7 and follows and hereunto set my hand this 5th day of June, 1871. engages with said ratchet-Wheel when said crank is turned forward, substantially as and for the purpose speoied.
