IM PROVEM ENT IN WATER- E'LEVATORS.

Specification forming part of Letters Patent N0. 54,276, dated May l, 1866.

To all 'whom it 'may concern.:

Be it known that I, STEPHEN L. AVERY, of Norwich, in the county of Chenan go and State of New York, have invented certain new and useful Improvements in Water-Elevators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,form ing a part of this specification, in Which- Figure l is a side elevation of my improved apparatus, with dotted lines, showing position of workin g parts, properly concealed from view. Fig. 2 is a top view of the same; Fig. 3, a detached view of the crank and ratchet with the outer confining-plate removed 5 Fig. 4, a vertical section through the sectional drum in the line a' x of Fig. 2; Fig. 5, a vertical section at right angles to the last in the line yy of Fig. 4; and Fig. 6, a side elevation of a crank and attachments, which may be substituted for that represented in Figs. l and 2 as an equivalent thereof.

Similar letters indicate like parts in all of the figures.

My improvements relate, rst, to the arrangement and combination of a weight with the annular friction-collar upon the crank of the windlass; second, in the combination of a central circular slotted washer with the annular friction-brake of the crank; third, in a novel construction ofthe wiudlass-drum; and, fourth, to the manner of constructing the valve-rod of the bucket.

Upon the outer end of the windlass-shaft A,

which is supported at either end in suitable bearings arranged upon the well-curb inthe ordinary manner,is secured a ratchet-Wheel, B. A pawl, G, pivoted to the Well-curb in front of the ratchet-wheel, falls upon and engages with the teeth'of this wheel. An outwardly-projecting ange, a, Fig. 3, is formed upon the outer face of the ratchet-Wheel B. (See Fig. 3.)

The crank D of the windlass is secured to a slight elongated collar, E, which ts very loosely upon the flange a of the ratchet-wheel B. This collar is provided with an inwardlyprojecting catch, b, so formed upon its upper inner side, as seen in Fig. 2, as that it will rest upon the teeth of the ratchet and engage therewith when turned in one direction, but when turned in the opposite direction, so as to slip over the teeth, willy catch against the end of the pawl G and lift it back away from the ratchet, leaving the wheel and Windlassshaft entirely free in its bearings. As the Weight of the crank would in itself suffice to raise the pawl and free the windlass, a counterweight, F, is-formed upon a projection on the pawl O is increased, the lower portion of the collar-say at e, Fig. 3-will be brought to bear against the ange of the ratchet-wheelsayatf--and will act as friction-brake against the same, enabling the operator to control at pleasure the revolution of the windlass-shaft. The crank and its collar are kept in place by means of an outer head-plate, F, Figs. l and 2,

' secured by a pin, c, running through the end of the shaft. Thus it is seen th at, by turning the crank D of my improved apparatus in the usual direction, (indicated by the arrowin Figs. l and 3,) the catch b, engaging with the teeth of the ratchet-wheel, will carry it around, and thus cause the windlass-shaft to revolve so as to elevate the bucket from the well, the pawl C at the same time clicking in the teeth to prevent an accidental reverse movement. If, however, the movement of the crank be reversed the catch g', engaging with the pawl C, as seen in Fig. 1, will disengage it from the teeth of the ratchet-wheel, leaving the windlass perfectly free to turn, except so far as it maybe checked by the friction of the collar E against the flange a on the face of said Wheel, this friction being obtained by pressure upon the crank D, Which acts as a lever, having a fulcrum at its point of contact with the pawl G.

The windlass-drum of my improved apparatus is constructed of two metallic sections, which may both be cast in the same mold. These two sections are each formed, as seen in Fig. 4, of circular side plates, G and G, whose edges curve outwardly, each having an annular flange, d d', of about one-half its diameter, projecting inwardly therefrom, so that when the sections are placed together these flanges meeting will form the drum, as seen in Figs. 2 and 4.-. To secure coincidence of contact between the edges of these annular flanges d and el', when brought together to form the drum, transverse cleats g g are formed upon the inner periphery of the anges,and made to project somewhat beyond the edge thereof, so as that when the two anges el and d are brought together the ends of each cleat will catch under the edge of the opposite flange, as seen in Fig. 4, and thus prevent the edges in contact from slipping. The two sections forming the drum are slipped upon the windlassshaft and kept from turning thereon by means of lugs 7c la, Figs. 4 and 5, upon the shaft, which it into corresponding recesses in said sections, as clearly illustrated in Fig. 5 of the drawings. The rear section, G, slips back against a collar, i, on the shaft, and the front section, G', after being brought closely against the rst so as to form the drum, as seen in Figs. 2 and 4, is secured by means of a pin, fm, driven through an aperture pierced in the shaft, Fig. 4.

The bucket H of my improved apparatus is elevated by means of a band or strap, L, equal in breadth to the width ofthe drum, as seen in Fig. 2. It is provided with a bottom valve, M, and discharge-spout of the ordinary form, as seen in the dotted lines, Fig. 1. The bail of the bucket is so proportioned in length as that when the bucket is fully elevated its rim will strike against the windlass-drum, and thus cause its bottom edge to be thrown forward against the well-curb, which is fitted with discharging-spoutat this point, into which the mouth of the spout in the bottom of the bucket will project when thus thrown forward. To raise the valve M at the moment when the bucket is thus lipped against the dischargespout of the curb, I secure a rigid arm, N, to the strapL, by which the bucket is elevated, so that it will project downward therefrom at an acute angle. The outer end of this arm YN is connected with the vibrating end of the valveM by means ofa rod, 0. When, bywinding the strap upon the drum in raising the bucket, it has reached the proper point for the discharge ofits contents, the arm N, passing over the periphery of the drum, is thereby thrown up at such an angle as to raise the.

valve in the manner illustrated in Fig. 1.

In order to lessen the weight upon the valve and facilitate its opening when let down into the water, I form the connecting-rod O in two pieces, s s', uniting them by-a sliding joint, as seenin the'dotted lines of Fig. 1, so that the weight of thelower section alone is supported by the valve M, the upper section being sus- 'tained by the arm N.

6 for tliathereinbefore described. This crank has a circular end plate instead of an annular collar, E, but of the same exterior dimensions. A central circular aperture is pierced in this plate, into i which is iitted a circular washer, K. This circular washer is pierced by an elongated slot whose width is equal to that of the end of the shaft A. The crank and washer are slipped upon the end of the shaft until the catch g rests upon the ratchet, as in the case of the crank D, and are then secured thereon by means of a simple pin,- p. This arrangement permits the crank to have the necessary play upon the shaft by means of the slotted aperture in the washer, and at the same time a rotary motion upon said washer, and as the whole is secured by the sim ple pin p no headpiece is required. ,The use of the weight F upon Athe crank obviates the necessity of springs, Svc.,` to accomplish the desired end.

Having `thus fully described my improvementsin water-elevating apparatus, what `I claim therein as new, and desire to secure by Letters Patent, is-

l. The combination, as herein described, of a weight, F, with the rim of a loose annular friction-collar, E,When said collar is combined with a crank, D, and with the ratchet-wheel of a windlass,'substantiallyin the manner and for the purpose herein set forth.

2. The combination ot' a central circular slotted Washer, K, with an annular friction brake and crank, D', and with a shaft, A, substantially in the manner and for the purpose herein described.

3. The metallicy windlass-drnln, when said drum is composed of two sections, G G, formed substantially as herein described, and united together and secured upon a shaft in the manner herein set forth. 4. In combination with the valve M of a well-bucket, a jointed connecting and lifting rod, O, made substantially in the manner and Y for the purpose herein set forth.

The foregoing specification of `my improvement in water-elevators signed by me` this 8th day of July, 1865.
