IMPROVEMENT IN WATER-ELEVATORS.

The Schedule referred to in these Letters Patent and making part of the same To all whom it lmay concern Be it known that I, JABEz K.,-BABcocK, of Shortsville, in the county of Ontario, and State of N ew York, have invented certain new and useful Improvements iu 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, making part of this specification, in which- Figure 1 is a vertical section of my invention;

Figure 2 is au elevation of the retaining-ratchet and crank; and

Figure 3 is an end view ofthe windlass.

The object and nature of my invention will be undei-stood by reference to the specication and drawings.

lo enable others to make and use my invention, I -will describe its construction and operation.

I use, for 'elevating the bucket, the ordinary windlass A, fig. 1, xed to the axle a, which is provided with suitable bearings in the curb B.

One end of this axle extends beyond the curb far enough to receive' the disk 'b and ratchet c.

The disk b is fastened securely to the axleand is .provided with, a flange, d, figs. 1 and 2,"projecting4 irom its outer face.

The ratchet c is tted loosely upon'the axle, beingl retained thereon by the nut n, and is engaged by the pawl m, iig. 2, pivoted to a convenient portion of the curb B, and held in Contact with the ratchet by the counterbalance m.

The crank G is 'pivoted to the face of the ratchet c, at considerable distance from its centre, as shown in lig. 1, and by dotted lines in iig. 2, and has secured to it, at the proper point, the stop o, which projects through a curved slot in lthe ratchet, and extends across the face of the flange don the disk b.

Whenpthe crank is in the position shown in full lines in iig. 2, this stop engages with a projection, n,

formed upon the disk near its outer edge; but when the crank is drawn back, as indicated in dotted lines, the stop is freed from the projection, and bears against the flange d.

It is desirable that the crank should always occupy the position shown in full lines in fig. 2, when the I bucket is at the point of discharge, sothat its weight shall hold the stop and projection n in preventing the bucket from descending.

To effect this purpose, I make the point of attachment of the rope or chain Dto the wiudlass adjustagcar, thereby same, whenever the rope stretches, or its length is varied for different locations.

The adjacent faces of the stop o and projection n may, if desirable, be so inclined as that they shall wedge 'together by pressure on the crank, thus tending to prevent them from unlocking when the crank is in any other position than the one shown.

rlhe operation of my invention isas follows:

When itis desired to lower the bucket, the crank is shifted upon the pivoted centre p, to the position shown in dotted lines in iig. 2, by which the disk and windlass are liberated, and the stop o made to act as a brake upon the iange d, controlling the speedof the descending bucket. The bucket being lined, a reverse movement 'of the crankin the direction of v the arrow, fig. 2, causes the stop to engage with the projection n, and the bucket is elevated andheld in any desired position by the ratchet c and pawl m. In place'of the perforated flange a and hook l, I may use hooks inserted in the drum of the win/dlass, and a ring secured to the rope and catching upon the hooks.

y Only one projection nis provided upon the disk b,

since, if more were used, they would neutralize the adjustment of the rope upon the windlass.

, What I claim asmy invention, and desire to secure by Letters Patent, is-

1. Ihecrank C, pivoted eccentrically to the loose ratchet c, and provided with a projecting stop, o, iu combination with disk b and projection n., for the purposes set forth. t

2, The Hange d, in combination with stop o and crank O, for the purpose specified.

3. 'llhepeiforated ang'e a and hook l, when used in combination with the ratchet c and` winch O, for the' purposes set forth.

.TABEZ K. BABOOGK.
