DAVID JONEs, Or MACHEN NEWPORT, wALEs.

Letters Patent No. 91,023,y dated J une 8, 1869.

INIPROVEMET IN WATER-ELEVATORS.

The Schedule referred to Ln these Letters Patentand making part of the same.

To all whom it may concern:

Be it known `that I, DAVID JONES, of Machen Newport, Wales, now temporarily residing in thev city, county, and State of New York, have invented a new and improved Mode of Raising Water; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to makeand use the same, reference being had to the. accompanying drawings, forming part of this specification.

This invention relates to new and important improvements in the method of raising water through a vacuum produced by the condensation of steam; and

It consists informing a vacuum by means of a tlexible bag, which is inflated by steam, which steam is condensed or allowed to escape.

And it also consists in measuring the steam which is discharged into the expansible and collapsible bag,

,thereby preventing undue pressure therein, as will be hereinafter more fully described.

The accompanying drawing represents an elevation of the machine, thevacuum-chamber and flexible bag being shown in section, and portions ol' the supplytube being broken away, in order to show to better advantage the nature and operation of the device.

A is the cistern or fountain.

B is the vacuum-chamber, into which vthe water is raised, and which contains the flexible bag.

C represents the bagfwhich is made of rubber, or other flexible water-proof material.

D is the supply-pipe.

' This pipe is connected with the chamber B, as seen in the drawing.

It has a check-valve at its bottom end for preventing the return ofthe water, as seen at e.

F is the discharge-pipe.

G represents a steam-boiler, for generating the requisite quantity of steam.

H is a measuring-vessel, from which the steam is expanded into the bag.

I isthe steam-pipe, which conducts steam from the boiler to the vessel H, and from thence to the collapsible bag G.

J is a pipe, by which the steam is discharged from the bag into a condenser, K, which is connected with the cistern A by the pipe L. n

It will be seen that there are two pairs of cocks, which are operated by rods, the cocks of each pair being connected together, so that they may be opened and closed simultaneously; the cock m, in the discharge-pipe F, and the cock n, in the steam-pipe I, being one pair, connected by the rod o, and the cock p, in the steam-pipe I, and the cock q, in thesteamdischarge pipe J, connected by the rod r, being the other pair.

When one pair of these cocks is open, the other pair is closed, and cioe versa.

Steam being discharged into the vessel H, will fill it at boiler-pressure, but the quantity is designed to be sosmall thatwhen it is expanded into the tlexible bag C,'it will expand only sufficiently to inflate the bag, and force out any air and water that may be con-` The bag O will collapse, and a vacuum will be-`r formed, more or less complete, ln the chamber B,

when the water will rise through the pipe D to till it. The bag is again filled or inflated as before, and the operation is repeated as long as may be desired.

The advantages of this arrangement are, that by measuring the steam through the vessel H, and 'expanding it therefrom, high steam is not allowed to enter the bag, consequently there can be no injurious pressure on the bag; and as the steam does not come iu contact with the sides of the chamber B, the condensation is slight, and the amount of steam to work the machine is very small.

Steam maybe taken from any source, as from a stationary boiler in any other situation, or fromA a locomotive, when taking in a supply of water at arailroad station.

I claim as new, anddesire to secure by Letters Patent- 1. In a device for raising wat-er by a 'vacuum formed by the condensation of steam, the expansible bag O, in combination with the air and Water-tight chamber B, substantially as described, for the purpose specified.

2. rIhe steam-measuring vesselH, in combination with an arrangement of devices for raising water by a vacuum formed by the condensation of steam, or by the discharge of steam, substantially as described, for the purpose specified.

The above specification of my invention signed by me, this 18th day of December, 1868;

. DAVID JONES.
