UNTTED STATES PATENT OEETCE.

M. C, BIGNALL, OF SENECA FALLS, NEW YORK.

iM PROVEM ENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. ll.90l, dated March 15, 1864; antedated March 14, 1864.

['o all whom it may concern:

' Be it known that I, M. G. BIGNALL, of Seneca Falls, in the county of Seneca and State of New York, have invented a new and useful Improvementin Apparatus for Drawing Water from Wells 5 and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specitication.

Figure l is a central vertical section of my improved machine, Fig. 2, an enlarged plan of the under side ofthe cross-board; Fig. 3, a perspective view of one of the socket-irons ot' the cross-board detached.

Like letters of reference indicate correponding parts in all the figures.

My improved machine is of that class where the bottom of the bucket is provided with a valve and spout for discharging the water when raised 5 and the invention consists in the use of a cross-board, provided with an opening or passage in which the chain runs, to prevent the counterbalance-weight from being` drawn up over the reel when the bucket is lowered, and to guide the chain and prevent it from displacement or disarrangement r on the reel.

.s represented in the drawings, an ordinary curb, A,is employed, in which is mounted the usual shaft, a, and reel B, over the latter of which passes the chain G, having at one end the bucket D and at the opposite a counterbalance-weight, b. The bucket is provided with a spout, c, port d, and a valve, f, whose stem or rod g projects upward through a cross-piece, h, ofthe bucket, and strikes against a board, E, to trip, as is shown clearly in Fig. 1.

The cross-board E is of peculiar construction. On one side, at a position to correspond with the rear portion ofthe chain, is made an opening or passage, lr, substantially of the shape shown in Fig. 2-that is, elongated in such a manner as to allow the at links of the chain to operate easily, but narrowed at the entrance, as shown at l, so as only to allow the chain to be inserted edgewise, but when once inserted not to be removed in its ordinary action.

There are two important advantages attained by this arrangement:

First. When the bucket is lowered to the proper degree to till with water, the further progress of the ,chain over the reel is stayed by the weight striking against the cross-board, as it cannot pass the opening k. Consequently there is no danger of the weight and chain being carried up over the reel, and lost in the well by turning the reel too far back, as is frequently the case in ordinary devices.

Second. By the chains resting in the opening k that portion which is turning on the reel is not affected by the swaying or other irregular action of the pendent portion beneath, for the cross-board always serves as a stay or guide to the chain above it. Thereforethe danger of the displacement of the chain from the reel, by reason of such irregular action or disarran gement of any kind, is obivated.

By the use of this device the chain can never get removed from the reel by accident, but is still readily placed in position or removed when desired, as it slips easily edgewise out or in the narrow opening Z.

For the purpose of obviating wear on the under side ofthe board, where/the valve-stem comes in contact with it, I prefer to cover a portion with a metallic plate, m, as representedin Fig. 2.

The usual manner ot' securing the crossboard in the curb is by nailing or screwing through from the outside. This splits the end of the board, which also decays in a short time, so as to be insecure against the strain applied to it. I employ at each end ofthe board a metallic socket, Gr, of sufficient size to admit the whole end of the board, and this socket is provided at each end with screwholes n n, by which means itis screwed fast to the inside of the curb.

By the employment of this device the board is easily attached or detached at any time, and is retained firmly in place. Its ends, by resting in the sockets, are never split or injured in any manner 5 and if any portion de- C and `reel B, substantially as herein set forth.

In Witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

M. C. BIGNALL.
