IMPROVEMENT IN WATER-BLEVATOR.

Mor-

The Schedule referred to in these Letters Patent and making part: cf the same.

To all whom 'it may concern.-

Be it known that I, D.-,A. DUNHAM, of Bilatka, in the county of Putnam, and State of Florida, have invented a new and improved l\Vate1"-11llevator; andI do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

This invention relates to improvements in devices used for raising or injecting water by a jet ofv steam. Those at present known to the public, which are constructed with reference to the same general principle yof operation as mine, are comparatively complicated and expensive, theV simplest of them consisting in' an arrangement of two pipes, one within the other, with the necessary accessories of pelforations and couplings, 85e., for connecting and preserving the proper relative position of the parts.

My invention, While effecting the4 same result, and operating in an analogous manner, consists of a single pipe of any suitable metal, the same having a transverse incision made in its under side, andthe shell' being bent in at that point, toform a throat or contracted passage, as will be hereinafter' more fully described.

The drawing represents a sectional elevation of my improved apparatus',

I take any suitable metallic pipe, A, and bend it into the form best adapted for the place to which it is tobe applied, for receiving and conveying the water, and provide the proper steam-connection at B, beyond the steam-connection, and preferably at the bottom, or

. that part of the pipe which can be placed in the lowest. position.

I make a water-receiving passage, C, bending the shell of the tube inward at the place where it is cut to form the said passage, so as to contract the steampas.

sage as at D, while opening the space C for the water.

The improved water-elevator herein described, consisting of a single pipe or tube, A, provided onits under side with a transverse incision, to allow the shell of the same to be bent inward at that point tn iorm a steam-passage, D, and also a water-passage, G, as and for; the purpose specified. v
