IMPROVEMENT IN WATER-ELEVATCRS.

Specification forming part of Letters Patent No. 153,974, dated August 11, 1874; application filed February 28, 1874.

` To all whom it may concern:

Be it known that I, J AMES F. MCCALMONT, of Webster City, in the county of Hamilton and State of Iowa, have invented a certain new and useful Improvement in Water-Eleva tors, of which the following is a full, clear, and exact description, reference being had to the annexed drawing, in which- Figure l is a perspective view of my improved water-elevator, and Fig. 2 a vertical central section of the same.

Corresponding parts in the two figures are designated by like letters.

This invention relates to a certain improvement in water-elevators; and it consists of a receiver or. lholder for retaining the bucket in an elevated position, suitably supported and pivoted over the mouth of the well, or over a conductor placed therein, and having a yielding inwardly-projecting lip, upon which a projection attached to the bucket rests when the latter is elevated, to retract which lip from the bucket a bow or lever piv ot'ed `to the lip is used.

To enable others to make and use my invention, I will proceed to describe it.

In the annexed drawing, A refers to a basepiece, which may represent the well-curb, to and lwithin the opening of which is suitably secured theconductor B, which guides the bucket asvitis being elevated into the receiver. C is the receiver, which is hung or suspended upon short axles extending from the inner sides of two uprights, D D, mor# tised into and rigidly secured to the curb A. The upper end of the receiver C is chamfered or inclined, as shown at o, and provided with a yielding or hinged lip, c', which rests upon the said inclined surface c of the receiver, and thereby ,caused to project or extend inwardly over the mouth of the receiver, so that as the bucket ascends and its projection passes the said lip, the' latter will be in position to let the projection oi the bucket rest thereon. After the bucket has vreached this point and its hoisting-rope has been slackened, it can then be tilted byprevolving the receiver, and thus be relieved of its contents or emptied. E is a bow, the ends of which are pivoted to the yielding lip c', and which is for the purpose of manipulating the receiver and its yielding lip.

In revolving or tilting the receiver C to tilt the bucket, the bow E must be pulled or manipulated so as not to retract the yielding lip c of the receiver from the bucket; or, in other words, the bow being in the position shown in the drawing, when grasped, pull it toward you. In pushing the bow from you, after the bucket and receiver have been tilted, by which they will be brought to a vertical position, the yielding lip o of the receiver will be withdrawn or retracted from the bucket, and the latter allowed to descend the well as its hoisting-rope is continued to be slackened.

A spring or springs, e, hold the lip c to its place, the former and latter being connected by cords e e or other suitable medium.

The hoisting rope, strap, or chain F, attached to the bail of the bucket G, passes up over a pulley journaled between studs upon the upper side of the top cross-piece of the uprights D D, and thence passes to and is wound around a suitably-disposed drum or shaft supplied with `E, and spring or springs e, in combination with the bucket or other receptacle G, having the projection g, and attached to a hoistingrope passing over a suitably-disposed drum, substantially as and for the purpose set forth. In testimony whereof I have hereunto signed my name this 24th day of January, 1874, in presence of two subscribing witnesses.`
