JOHN I). GRUBER, OF NEIN YORK, N. Y.

IMPROVEMENT IN PNEUMATIC LIQUID-ELEVATORS.

Specification tbrming part of Letters Patent No. 104,301, dated June 14, 1870.

To all whom it may concern Re it known that I, JOHN P. GRUBER, of New York city, in the county and State of New York, have invented a new and Improved Hydro-Pneumatic Elevator for Raising NVine and other. Liquors; and I do herebydeclare that the` following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making part of this speciiication, in which- Figure 1, Plate 1, is a perspective view oi" the improvedapparatus. Fig. 2, Plate 2, is a vertical section through the apparatus, with several of the communicating pipes arranged so as to show them in this section. Fig. 3, Plate 2, is a sectional view of the switch-cocks detached from the bodyof the apparatus.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to utilize the force or pressure of a head of water-such, for instance7 as may be desired from reservoirs used to supply cities and towns with waterfor the purpose of elevating wine and other liquors from cellars or vaults to upper stories of buildings.

The nature of my invention consists in an apparatus, hereinafter described, whereby air is forcibly expelled from two chambers through a single pipe by alternately allowing water to enter and escape from the chambers, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will describe its construe tion and operation.

In the accompanying drawing, A A1 represent two vessels, which are made of suitable strength to sustain the degree of pressure to which they are subjected. For convenience these vessels are connected together, one above y the other, by means of an intermediate cylindrical case, B, the interior of which shouldbe in free communication with the external air.

a represents an induction water-pipe, which should be connected to a pipe communicating with a head or reservoir of water. This pipe (t is applied to a valve-box, P, which communica-tes with the interior of vessel A1 by means of a connection, Gr, and also with the vessel A1 by means of a pipe, N. The valve-box P is provided with an oscillating two-way cock, b, having an arm, c, applied to its stem.

In Fig. 2 cock b is turned so as to cut off communication from the vesselA1 and allow water to enter vessel A through the pipe N. Below the pipe e is a water-eduction pipe, e, which is applied to a valve-box, P', which cornmunicates with the vessel A1 at its bottom by means of a pipe, G. Valve-box Il is provided with an oscillating two-way valve, b', having an arm, c', applied fast to its stem. The arms c and c' are pivotedto a rod, T, which is used for operating both valves b b at the same time for changing the direction ot' the currents, as will be hereinafter explained.

In Fig. 2 valve b is represented `in position for cutting 0E the escape of water from the vessel A by way of pipe B', and allowing water to escape through pipe a from vessel A1 by way of pipe G. The upper vessel, A, isfpro; vided at its top with an air-inlet valve, s, which valve will prevent the escape of air through it. Vessel A is also provided at its top with a valve-box, D, containing an air-valve, c, which closes downwardly upon its seat; also, with a valve, j', which closes upwardly against its seat, and which is applied to a vertically-movable stem having a ioat, F, on its lower end. When water rises above a given height in ves sel A the valve f will be buoyed up by oat F, and by closing the outlet-passage into pipe A2 prevent farther entrance of water into the vessel A.

The pipe B is intended for conducting oit' the water from vessel A, through valve b and pipe a', during the introduction of water 'into vessel A1. The pipe A2, which leads out of valve-box D of vessel A, and also out of the valve-box D of vessel A1, communicates with a common air-pipe by means of the branch pipe O.

The vessel A1 is provided at its top with an air-inlet valve, s', which, like valve s, will prevent the escape of air through it. A valve-box, D', is also applied to vessel A1, and provided with two valves, c f', and a float, F', which operate precisely like corresponding parts applied to valve-box D, and above de-l scribed. G is the water-outlet pipe for vessel A1, and is in direct communication with outlet-pipe c when valve b is adjusted as shown in Fig. 2. Air will enter the case B through a space left around the air branch of the valvebox D.

Operation.

By depressing the rod T valves b b' will be adjusted as shown in Fig. 2. Valve b will cut oft' communication between vessel Al and inlet-pipe a and open a communication between pipe a and vessel A through pipe N. Water will then low into v'essel A and out through the valve-box D into pipe A2 and close valve c' in valve-box D'. From pipe A2 the air will escape through pipe C. While this is taking place water will be allowed to escape from ves sel A1 through pipes Gr' and a', and this vessel will jill with air, entering it through valve s'. The rod T being raised valves b b' will be adjusted as shown in Fig. 3, when the inflow of water will be cut oft from vessel A and the iniiow established into vessel A1. At the same time valve b' will prevent the escape of water from vessel A1, but allow its escape from Vessel A through pipes B' and a'. 'Vhile the vessel A1 is being filled with water and its air forced out through pipe A2, (valve c being shut,) the vessel A will be filling with air and its water escaping through pipes B' and a'.

The float-valves f f' are safety-valves to prevent water from rising so high in either one of the vessels A A1 as to enter the air-outlet pipe A2.

In practice I shall arrange the apparatus in a cellar or vault containing the liquor to be raised.

The rod T will have a weight or spring applied to it for drawing it down to the position indica-ted in Fig. 2, and by means of a wire or rope carried up to the apartment into which it is desired to elevate the liquor. The rod T can be raised, as indicated in Fig. 3.

A flexible pipe is applied to the air-branch C, and made to communicate, in. a suitable manner, with a barrel from which it is desired to force liquor to an upper story. From such barrel a pipe is carried up, and through this pipe the liquor is forced by the introduction ot' air into the barrel from the apparatus.

Having described iny invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the vessels A A1, two-way cocks b b', passages G G' N B', inlet air-passages s s', and valved outlet air chainbers or passages D D', substantially as and for the purpose herein described.

2. The combination of the iioats and valves F F fj" with the vessels A A1, cocks b b', passages s s', valved outlet air-passages D D', and pipe A2 C, substantially as described.

3. The arrangement of the two-way cocks b b', links c c', rod T, pipes B' N, and inletvalves s s', applied to chambers A Al, which are provided with air-outlet passages, substantially as and for the purpose described.
