Letters Patent No. 109,042, dated November 8, 1870; antedated October 29, 1870.

IMPRQVEMENT IN HYDRAULIC APPARATUS.

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

To all whom 'it may concern.-

Be it known that I, NICHOLAS NOLAN, of the city of New York, in the county and State of New York, have invented a new and improved Hydraulic Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, which will lenable others Skilled in the art to make and use the same',` reference being had to the accompanying drawing forming part of this specification.

Theidrawing represents a side view, )artly in Section, of my invention. l .The object of this invention is to provide means for elevating, without additional power, water or otherv liquid to .a 'greater height than at 4which it has its original level.l

,The invention consists in the introduction to a vertical water-'pipe of a self-acting siphon,whereby the desiredresult is obtained. i'

' The invention -is chiefly applicable to buildings which have some stories higher than the reservoir from which their water supply is taken.

- A in lthe, drawing represents the supplyppe,the end a being shown on the level of the reservoir from which the water is taken.

From this level the pipe A extends downward a suitable dist-ance in the arm b, and is then carried horizout-ally at c. f

From c the pipe A extends up again to d, until it reaches a vessel, B, which is labout on a level with a.

From the lower part of the vessel B projects upward a pipe, C, which is almost, but not quite, as long as the arms b or d.

A Siphon-pipe, I), having a Stop-cook, e, near its lower end, connect-s the arm c with the vessel B, as Shown.

The cock e being closed, the water/will pass from o intol), c, and d, iiniling its level in the vessel B.

.Lhclsiphon will contain air, which is confined by the cock e at one cud, and the water in B at the other end.

In this position the water can be drawn from 'the parts b, c, or d, at will, and will'always be replaced.

When, however, water is to be taken from the upper pipe C, the cock e nnst be opened then the water from the reservoir will rush into the Siphon D, and will force the air which was formerly confined therein into the vessel B. l

The upward pressure upon the column of water in d causes a check-valve, g, at the lower part of cl to be closed. Y

rlhe air which was confined in the pipe D will force the water that was iiirmerly contained in the vessel B out through the pipe C. Only lwhen the air in B reaches low enough to be in line with the lower end of the pipe C will it escape. Thus a column of water, equal in extent to the column of air confined in the Siphon, can be elevated beyond the water line.

In order to increase the elevating capacit-y, an en'- larged chamber, E, is or may be formed on the Siphon.

The bottom oi' the vessel B is inclined, so as to bring the end of the pipe C as low as possible.

\Vhenal1 the air has been driven from the pipe D, the water is withdrawn from the loweiend of the Same through a faucet l1.

At thc upper end of the pipe D is arranged a valve' or oat, i, which will be closed by water, but not by air. Thus, all the water can be drawn from I), as

none can enter the upper end.

Should the air have escaped from the vessel B through C, the vacuum in D will be filled by air drawn in through a self-acting valve, j.

As soon as the pipe'D is again filled with air,` the elevating process can be again carried on.

Within the pipe O is arranged a valve, I, which will prevent wat-er once in C from flowing back into-B.

Having thus described my invention,

I claim as new and desire to secure by LettersA Patent- The U-shaped supply-pipe A, having valve g, and a Siphon, I), having faucet-valves andcock, as described, combined with a vessel, B, and valve dischargepipe G, all relatively arranged as and for `the purpose described. ,A

NICHOLAS NOLAN.
