TO ALL WHOM IT MAY GONCERN:

Be it known that I, C. F. WOODRUFF, of Newbern, in the county of Dyer, and State of Tennessee, have invented a new and improved Wheel and Axle; and I do hereby declare that the following is a full, cleaaandl exact description thereof, which will enable those skilled inthe art to make and use the same, reference being;

had to the accompanying drawings, forming part of this speciiication.-

This invention relates to an improved wheel and axle, and is specially applicable to the raising of water from wells. It consists mainly of a drum, round which the rope. coils, and through the axis whereof the axle passes, which can be connected and disconnected at pleasure, so as to enable the bucket to descend without the crank beingrevolved. In the accompanying drawings- Figure I is a vertical section of my improved wheel and axle, at line y y of Figure 2, which is a side view thereof Figure 3 is a side view ofv drum, and

Figure 4 is a. section thereof at line a: :n of tig. 1.

Similar letters of referencejndiate corresponding parts.

A is the crank, B the axle, C the drum, set upon the axle B, and on which coils the rope c, to which the bucket orweight .is attached. A shaft b, having a thumbpiece, bfpasses into thea-xl'e B, and screws into the bnr D, which passes through the slot b in the axle B. A disk, E, may be used, fitting into the ring F, and

another disk, G, serves to hold the axle to its place, while the nut H, screwing on .to the worin h, near the other` extremity of the axle, serves the like purpose.

To operate the wheel and axle, the handle or thumb-piece b is pressed in, carrying the bar D down the` slot b until it clutches the stops d d, cast upon the ring F. To release Vthe drum without revolving the crank A, the thumb-piece b is drawn out, unclut-ching the drum, which is then free to revolve, allowing the weight or bucket to descend, its velocity being regulated at pleasure by the break I, or the drum C may be connected with and disconnected from the axle B by any equivalent device'.

Y K is a free pulley, set on the axle k, to carry the bucketaway from the frame z down the well or other desired direction. Lis a p awl, acting on the stops lll to prevent the crank from dying back while connected with the drum.

I claim as new, and desire to secure by Letters Patent v The shaft b, working in the axle B, having the bar D at its extremity, working through the slot b", clutching the drum C by the stops d, in manner substantially as above set forth and described.
