SPECIFICATION forming partof nettetgi atent No. 654,7 dated J V 31, 1900- Application filed r1115 8, 1899. ,Seriallio. 723,233. (No model.)

To all whomit-may concern;

Be it known that I, MARION NOEL SCHAUF- FLEBERGER, a citizen of the United States,re-

siding at Bristol, in the county of Washington and State of Virginia, have invented new anduseful Improvementsin Pneumatic Water-Elevators, of which the following is a specification. I

My invention relates to pneumatic waterelevators of that class or character in which a tank is located in a well, mine-shaft, or other place and isprovided with an inletvalve, an outlet-pipe, and an air-pipe for forcing air into the tank, whereby the water is displaced from the tank and forced up through the outlet-pipe to the top of the well or shaft.

The object of the invention is to provide an improved construction of Water-elevatorwhereby when the water in the tank falls below a predetermined level the air-pressure will be automatically reduced by the open-.

ing of a valve in ,an exhaust-pipe, allowing water to enter the tank until the proper level is reached,- whenthe valve will close and the water be forced up the outlet-pipe.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a central longitudinal section of a water-elevator constructed in accordance with my invention. Fig. 2 is a detailed sectional View of a modified construction of the air-pipe valve.

In Fig. 1 I haveshowna double-acting elevator provided with a housing 16 at the upper end, with which the air-pipe 5 communicates. The tank is divided bya central partition 17 into two compartments 18, in each of which are located an outlet-pipe 3, exhaustpipe 7,- pivoted arm 8, valve 9, float l3, and inlet-valve 2.- The outlet-pipes come together above the tank and are connected with a single discharge-pipe. (Not shown.) Located in said housing is a horizontal lever 19, each end of which is provided with a valve 20, which engages with a seat 21 in the upper end of short air-pipes extending into the tank. Said lever is also provided'with rods 23, which pass down through the said air-pipes and are provided with arms 24, the lower ends of which are formed with slots, through whichthe arms 8 loosely pass. The operation of this construction will be readily understood. As one *fiqat rises to close the exhaust-P pers that theairQpressure will force the water 'out of the outlet-pipe, the float in the other compart ment will fall to reduce the air-pressure and allow water to enter the compartment. By this means the operation of elevating the water will be continuous, as while one compartment is discharging the other will be filling. A suitable strainer may be placed at the lower end of the tank, as is usual in waterelevators.

In Fig. 2 I have shown a modified construc-' tion of float and valve for the e haust=pipe. In this instance the numeral 25 designates avertically movable tube telescoping upon theeXhaust-pipe'and provided at the upper end with an arm 26 and at the lower end with a float 27. Said tube is formed with an open ing 28, adapted to register with a corresponding opening 29 in the exhaust-pipe. The 0poration will be readily understood. When the float falls, the said openings will come into coincidence and the air in the tank will escape through the exhaust-pipe. When the float again rises, the openings will close. The numeral 29 designates a rubber bumper carried by the float.

Having thus fully described my invention, what I claim is% In a dnplex pneumatic water-elevator, the combination with the tank divided bya central partition into two compartments, each having an inlet-opening in thebottom provided with avalve, the outlet-pipes, the exhaust-pipes, the pivoted arms provided with valves,the rods pivoted thereto and the floats, of the housing at the upper part of the tank,

the air-pipe communicating therewith, the I pivoted lever having a valve at each end, the air-pipe with which said valves engage, the rods connected with said lever passing through said air-pipes, and the bars connected therewith having slots at the lower ends through which said pivoted arms pass, sub- .stantially as described.

In testimony whereofl have hereunto set myhand in presence of two subscribing witnesses.

MARION NOEL SOHAUFFLEBERGER.
