TO ALL WIIOM IT MAY CONCERN:

De it known that I, THOHAS HOLMES, of Bristol, in the county of Bristol. in the State of Rhode Island, have invented a new and useful Improvement in Well-Curbs and their Mechanism for Drawing W'ater; and I do hereby declare that the following is a full and correct ydescription thereof, reference being had to the accompanying drawing, forlning part o-f this specification, and to the letters of reference marked thereon.

' The drawing shows a side view partly in perspective, with a portion of the side of the curve removed to sho'iir the arrangement of a part of the mechanism.

The construction is as follows: A-is the body of the curb, which may be of the usual form. A drumLB, is placed across the cui-b, having its pivots resting in bearings a in the `sides of Athe same. .A rim, C, having cogs on its inner surface, is secured on the end ot' the' drum B, and a smaller wheel or pinion, D, with cogs, is fastened toa short crank-sinift, S, which shaft is placed in a bearing, L, so as to bring the eogs of the pinion D tovmesh 'into those on the rim O, so as to drive it when the crank It, upon the outer end of the shaft, is turned; G- is a lever placed across the side of the curb under the rim C, and is hinged to the bach side of the curb. This lever forms a brake to press against the outside ofthe rim C, to regulate tl-iefde-se'ent of the bucket i-nto the well. A ratchet-wheel, E, is fastened to the crank-shaft beside the pinion, into which the paw] I" arranged to fall, to hold the drum from turning when required. This pawl F is connected to the brake-lever by thebar Z, so that when it is desired to let the bucket down, by raising the lever G, to bring the brake to bear to control the speed of its descent, the pawl is raised out of the ratchet-wheel by the bar Z, so as' to allow the drinn to turn.

4 Some of the advantages of this arrangement are that by the use-of the gear-wheels a larger drum than usual can be used, so that where a well is deepl the drum will havemoreroom feria ropc ofgreat length withoutthe necessity of winding one coil or layer over another, which wears the rope out fast, 4or carrying the bucket too far to one side ofthe. spout to be caught and tipped when drawn up. Also by using gear-wheels of this description the crank and drum will revolve in the same'direetion, which Ais a great convenience. The facility with which the brake-lover and pawl can bc operated by one motion make a very handy arrangement, which, in an article in such continual use, amounts to a great deal in the course of time. A cover, P, to the curb is shon'n in the drawing, also a plan for tipping and emptying thebneket; but as these are not claimed as new, they will only b'e mentioned.

Having thus described my improvement, what I claim as my invention, and desire to secure by Letters Iatent, is as follows:

I claim the combination of the brake-lever G and pawl F with the gear-wheels D C, when arranged subtantiully as described and for the purpose set forth.
