Description

UNITED STATES PATENT oEEicE.-
ALBERT JOHNSON, OF PUTNAM, CONNECTICUT.
WATER-ELEVATOR.
Specification of Letters Patent 1\To.l 36,409, dated September 9, 1862.
To all whom 'it may concern: Y l
Be it known that I, ALBERT JOHNSON, of Putnam, in the county of Vindham and State of Connecticut, have invented a new and useful Improvement in I/Vindlasses for Wells; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the ac.- companying drawings, making a part of this specification, in which- A Figure l is a front view of my invention applied to a well-curb. Fig. 2 a side sectional view of the same, taken in the line m, m, Fig. l, a portion of the crank mechanism being also in section. Fig. 3 a detached sectional view of the crank mechanism, taken in the line y, y, Fig. 1.
Similar letters of reference indicate corresponding parts in the several figures.
The object of this invention is to obtain a well-windlass of simple and economical construction by which the bucket may be raised with facility and allowed to fall at any time, or from any point at t-he will of the operator, and without a reverse movement of the crank.
Vell-windlasses of this class have been previously devised; but, so far as I am aware they have all been complicated in their arrangement, involving the necessity of reversing the movement of the crank in order to release the bucket, and thereby not admitting of the operator having that control over the device that he should have in order to avoid the bucket being injured by a too rapid descent in the well, and also by a casual releasing of the bucket.
My invention it is believed fully obviates this diiiiculty, and by a very simple means, which is not liable to get out of repair or become deranged by use. Y
To enable those skilled in the art to fully understand and construct my inventionI will proceed to describe it.
A, represents a well-curb which may be constructed in any proper way, and B is a drum the shaft C of which has its bearings on the upper part of the framing of the curb. The drum is permanently attached to its shaft C turning with it, and one end of said shaft has a wheel D attached permanently to it. This wheel has a smooth periphery, and is at the outer end of the curb fralne.
E is what may be termed a crank-boX which is of oblong form, and cylindrical at one end, so as to inclose the wheel D, This crank-box is fitted loosely on the shaft C, the latter passing through its sides at each side of the wheel D. The inner side of the crank-box E has a ratchet F attached to it into which a pawl G, secured to the curb frame catches. The ratchet F is, like the crank-box, tted loosely on the shaft C.
H is a slide which is placed in the crankbox E, and has a piece of india-rubber, leather, or other suitable elastic or yielding substance c to its end which faces the periphery of the wheel D, see Figs. 2 and 3. This slide H has a spring I bearing against its outer end and this spring has a tendency to keep the slide in contact with the periphery of the wheel D. The outer end of the spring I is in contact with a bar J, one end of which passes through an oblong slot b in the outer side of the crank-box, and has a screw K pass-ing through it, said screw passing through the end of a small boX-c, attached to the crank-box E, and fitting in an internal screw thread in J. By turning the screw K the bar J may be moved within the crank-box and the strength of spring I graduated as desired, to regulate the pressure of the slide H on the wheel D. This will be fully understood by referring to Fig. 3. The slide H has one end of a bar L attached to it, the opposite end being connected to or fitted on a pin d which is attached to a small pulley c, at a point some distance from its center or axis-see Fig. 2. The slide H and pulley c, are both within the crank-box E, and thepulley is fitted on a shaft or rod M which passes through the outer side of the crank-box and through a handle N, by which the crankbox is t-urned. The outer end of the shaft or rod M has a small thumb-wheel O secured to it. VThe slide H it will be seen serves as a brake and connects the crank-box brake Hfrom the wheel D, and thereby dis connect the crank-box E` from the shaft C, so that the latter will be left free to turn and the bucket P allowed to descend by its own gravity. The speed of the descent of the bucket may be regulated'as desired by? graduating the pressure of the slide or brake H on the Wheel D, andthe `instant the` operator releases the shaft or rod M, the spring I turns the slide or brake H in contact with the wheel `D and connects `the, crank-box with the shaft C.
The arrangement is extremely simple and under the complete control of the operator, as the liberat-ion of the bucket from the crank-box does not depend upon a reverse movement of the latter, and consequently the bucket is not liable to become casually or accidentally liberated, a contingencyY which not unfrequent-ly occurs in using those hitherto devised.
Having thus described my invention, what I claim as new, and desire to secure by`Letl ters Patent, isv l. The crank-box E placed loosely on the shaftA C, and provided with the slide or'` brake H, spring I, pulley e, and bar L, in connection with the wheel D attached per- -manently to the shaft C, and placed within the crank-box, all being arranged to operate substantially as and for the purpose set forth.
2. Ifurther claim the graduating of the WM. J. STONE, I. MANNING.
