WATER-LIFT.

SPECIFICATION forming part of Letters Patent No. 506,996, dated October 1'?, 1893. Application filed February 20,1892. Serial 110.422.276. (No model.)

To all whom it may concern: I

Be it known that I, GEORGE P. GLENN, of Fairfield Suburb, Jacksonville, in the county of Duval and State of Florida, have invented a new and Improved Pneumatic Tank-Feeder,

.of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which- Figure lis a side elevation, partly in section, of myimprovedwater lift as adapted to feeding the tanks ofY locomotives. Fig. 2 is alongitudinal section of Ythe power-shifting valve;

and Fig. 3 is a vertical transverse section of v v one of the displacement-ball chambers.

Similar letters of reference indicate corresponding parts in all the views.

The object of my invention is to construct a device for lifting Water for any purpose, by the application of compressed air, steam or gas from any convenient source; but especially adapted, as illustrated in this case to the feeding of locomotive Water tanks by means of compressed air from the air reservoir of the air-brake system or by means of C', each of which is provided with a siphonv tube, d, extending into the tank and downwardly toward the bottom of the same. Below each Siphon tube d, is an aperture e, for

establishing a second communication betweenV the tank and the displacement-ball-charnber, and in the top of each ball-chamber, is avent aperture f, below which is a cage g, which contains ,a ball-valve h, which is capable of closing the aperture f, by floating.

Rods DD', extend vertically through the j' displacement-ball-chambers and each carries displacement ball E or E', Whose specific .v`V

gravity is greater than that of Water. The ball rods D, D' extend upwardly above the surface o f the Water and are connected with a steel belt, cord or chain l,which extends over the valve operating pulley j.

In the tops of the tanks B, B', are inserted compressed air, steam or gas pipes F, F', which are connected with the valve chest G, through ports lo, lo'. In the bottom of the valve chest are formed exhaust ports Z, Z'. In the valve chest G, is placed the valve H, having three compartments m, fm.' and fn. In the valve chest G, is j ournaled a shaft I, upon which, outside of the valve chest is placed the pulley j, While on the said shaft inside of the valve chest is secured an eccentric o, 6- which revolves about its own axis and vibrates above the shaft, in the compartment n, of the valve H. A compressed air, steam or gas supply pipe J, is connected with the upper portion of thev'alve chest.

In the tanks B, B', are inserted the discharge pipes K, K', which are bent at right angles above the tanks and are connected with the discharge pipe K2, and extend downwardly below the level of the Siphon tubes d. The horizontal portions of the pipes K, K', are axially inline, and Within is supported a guide p, upon which is placed avalve q, which is capable of closing either the pipe K or K'.

The pipe K2, extends under or above the surface of the ground after making a rightangled turn near the top of the well, and is, in this particular application, provided with a pivoted and counterweighted nozzle L, which is adapted to discharge into the locomotive tank.

The compressed air, steam or gas supply pipe J, extends along under or above ground, parallel with the pipe K2, and is provided, in this case, with a nozzle M, connected with it by a flexible tube o", the nozzle M, being attached to the nozzle L, and arranged to con- .nect with the compressed air or steam pipe J', carried by the tender and taking compressed air from the compressed air reservoir r2 of the air brake system or steam from the boiler of the locomotive.

When the tank is to be filled, the nozzle L is lowered and the nozzle M is placed in connection with the compressed air or steam pipe J ',:the air or steam valve s2, is opened and compressed air or steam passes through the pipes J, J', the valve chest G and the pipe F, into the tank B, the valve H being at this time, in the position shown in Fig. 2, that is to say, with the port lo open, so as to allow the compressed air or steam to pass through the chest G, and through the pipe F', and with the port k thrown into communication with the exhaust port Z through the compartment 'm of the valve H. Under these conditions, the water contained by the tank B' is forced by air or steam press-ure through the pipes K', K2 and the nozzle L into the loco,

motivetank, the valve q, opening automatically and closing the pipe K as the water rises in the pipe K.

The tank B, having previously been emptied in a manner similar tothat just described, by the pressure of water in the well, the exhaustisdriven through the pipe Fand valve chest G, and the water enters through the openings b and fills the tank B more rapidly than B.' can be emptied. As the tank B fills, water enters the ball-chamber 0 displacing aperture f, and as soon as the ball chamber is full of water, the valve h, closes the aperandthe displacement balls E, E', be-

turo g, ing o equal size and of equal specific gravity, y y

3o will hang in equilibrium over the pulley 72,

until the tank B' is emptied. As the latter tank becomes empty, the` water in the ball--Y chamber C' iiows out into the said tank B",

water now displaced by E, lifts thev ball E4 to the upper en d of the ball-chamber C and i11- self drops te the lower end of ball-chamber 4o, C',v thus turning the pulley j and shaft I, shifting the valveH by means of the eccen from the tank B", through the pipe F',1 port k' and exhaust port Z', whileV thev compressed air or steam from the locomotive passes through the valve chest G, port la' and pipe F into the tank B, forcing the water through the pipes KK2 and nozzle L,-as in the other caseat the same time, shifting thevalve q so and filledl withA water alternately...
