IMPROVEMENT IN WATER-ELEVATORS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM H.'CAsTLE, of Washington city, in the District of Columbia, have invented a. new and useful Improvement 'in Water-Drawers; and I do herebydeclare that the following is a full and com-4 plete description of the construction and operation of the same, reference being had to the'accompanying drawings making part of this specification, in which- Figure 1 is a perspective view, and

Figures 2'and 3 enlarged sections.'

Like letters refer. to like parts.

' In iig. 1, A represents the well-curb. Itmaybemade in the square, rectangular, `or any other convenient form,for supporting the windlass and other parts. B represents the windlassfshaft, which is mounted upon the top of the curb in appropriatejournal-boxes. `C represents the windlass, upon the shaft B, around which the rope, D, is wound, in raising the bucket, E, from the well. 'F is the spout, into which the water isvdischarged from the bucket E. I l v The shaft B extends beyond the curb A, on the front side, for the purpose of receiving the ratchet-wheel G, which works loosely upon the shaft B.' H'represents a pawl, which is pivoted to the'curb Aand engages with the ratchet-wheel Gfand is held in contact by means of its own gravity. This ratchet-wheel has a rim, I, projecting outward from the face of the wheel, as shown in gs. I and 2, and which is recessed at one point, I, to receive the crank, Ii. Y

The crank, K, where it fits'upon the shaft I3, is provided with an oblong slot, L, and is held in contact with the shaft by means of a spiral spring, M. A single tooth, N, projects from the head of the crank inwardf towards the shaft B, and engages with the teeth upon a wheel, presently to be described, the position of which upon the shaft B is represented by red lines in g. i2.

In figs. 1 and 3, O represents a cap, which vfits upon thc end ofthe shaft B, and to which it is firmly secured by, means of the pin P, which passes through the collar of the cap, and through the shaft, thus fastening them together. Upon the inside of this cap O, and forming a part thereof, is a toothed wheel, Q, the position of which, when in place, is represented by the red lines in iig. 2; and, as before stated'7 the tooth N, upon the head of the crank, engages with the teeth Vof the wheel Q, in which position it is ordinarily held by the spring M, and when-the crank is rotated in the direction of the arrow in the figures, the shaft B and windlass C are rotated also, by means of the engagement of the tooth N .with any one of the teeth in the wheel Q, and by this means the bucket is raised from the well.

When it is desirable to let the empty bucket descend into the well, the crank is drawn backward in the direction opposite tothat indicated by the arrow, the pawl H acting as a fulcrum for the crank, and this act, by compressing the spring M, releases the tooth N from its engagement with the wheel Q, and the bucket descends into the well by its own gravity, thereby unwinding the rope from the windlass C. When this is, accomplished, and it is desired to raise the bucket again from the well, by a movement of the crank in the direction of the arrow, the tooth N immediately engages with the 'wheel Q, and thereby causes the shaft B and windlass O to turn in the direction -of the arrow, and elevate the bucket. I

What I claim as my invention.v and desire to secure by Letters Patent, is-

The combination-.of theslot L, in the crank-head, the spring M, the tooth N, cap O, and toothed wheel Q, when constructed and arranged as and for the purpose set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

WM. H. CASTLE.
