SPECIFICATION forming part of Letters Patent No. 565,615, dated August 11, 1896.

` A Application inea my 18,1896. seriainatgioso. cromati.)

To all whom it may concern.'

Be it known that LLOEENZ SGRossMAN, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State 5 of Ohio, have invented certain new and useful Improvements in Apparatus for Pumping Liquids by Fluid-Pressure, of which the following is a specification, the principle of the invention being herein explained and the 1o best mode in which I have contemplated applying that principle, so as to` distinguish it from other inventions.

rlhe annexed drawings and the following description set forth inpdetail one mechanical form embodying the invention such detail construction being but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawings, Figure I reprezo sents a perspective view of my improved pumping apparatus, illustrating the application of the sameg, FigII, a vertical section of the faucet and Valve mechanism; Fig. III, a horizontal section of the valve mechanism; Fig. IV,`a transverse section of the faucet and valve mechanism, and Fig. V an axial section of the inotor-cylinder and the pump-cylinder.

The apparatus forming the subject-matter of this application is principally designed for pumping liquids by suction, and by means of fluid-pressure, from a receptacle and out through a faucet.

A pump-cylinder A is provided with a suction-tube a, entering the Cask or other liquidreceptacle, from which the liquid is to be drawn. The inlet into the cylinder from the suction-tube is controlled by an upwardlyopening valve a. A piston a2 reciprocates within the pump-cylinder, and has an upwardly-opening valve d3. The piston-rod a4 passes out through a stuffing-box in the head of the pump-cylinder and enters a motorcylinder B through a stuffing-box in the head of the latter. The pump-cylinder has an outlet a5, from which a tube a6 leads to a faucet C, which will be referred to later. The piston-rod is secured to a solid piston b, within the motor-cylinder, so that lthe pumppiston may be reciprocated by reciprocating 5o the motor-piston, which is accomplished by alternately admitting and exhausting water dies the faucet.

The faucet is secured to and passed through the wall of a refrigerator, ice-box, or anyV other support, and the faucet has a transverse plug C', to which a handle C2 is secured by a yoke which strad- A valve-Casin g D is secured to the inner side of the wall or support and to the faucet-shank, and said valve-cas- 6o ing has a tube d longitudinally secured in its interior. The forward end of said tube is closed by a stuffing-box d', and the rear end is closed by a plug d2. The tube has iive annular ports, formed by annular rows of perforations d3, d4, (Z5, d6, and olf", which communicate with five annular chambers D,D2,

DE", D4, and D5, formed in the valve-Casin g by four partitions (Z8, which support thetube. The tube forms a cylindrical valve-chamber, 7o in which a two-piston valve E reciprocates. The valve-casing has a water-inlet D,I which communicates with the middle annular chamber and port, and which is connected to a source of water or other iiuid under pressure. The distributing chambers and'ports, at either side of the middle chamber and port, are connected by tubes b' and b2 to the ends of the motor-cylinder, `and the end chambers and ports are connected by a channel D7 to 86 a water-outlet DS. The two-piston valve in the water-chamber has a rod e, which slides through the stuffing-box at the end of `the valve chamber, andis connected to the faucetplug handle by a link c.

The faucet-plug is illustrated in the draw-` ings as closed, with the handle tilted back, and the distributing slide valve consequently moved back. This will place the rear distributing-port, which leads to the upper end of 9o the motor-cylinder, in connection with the water-inlet, and will cause the pistons to be depressed, so that the liquid which on the upstroke was drawn into the pump-cylinder below the piston will be forced through the pump-piston into the upper portion of the pump-cylinder.

The forward distributing-port, which leads to the lower portion of the motor-cylinder, is connected to the forward waste-port, and waroo ter can thus pass from the lower portion of the 4cylinder to the waste. As both valvepistons have at all times their outer faces exposed tothe Waste and their inner faces to the pressure of the actuating-water, the distributing-valve will be balanced in its forward or rear position. When it is desired to draw liquid, the faucet-handle is tilted forward, opening the faucet-plug and draw-ing the distributing-valve forward. This will place the forward distributing-port and the lower end of the motor-cylinder in communication with the inlet-portand will uncover the rear distributing-port and the upper end of the motor-cylinder to the waste. The pistons in the motor/and pump cylinder may thus move upward and the liquid above the pump-piston will be forced through the faucet, while liquid will be drawn into the portion ofthe pump-cylinder below the pumppiston. By means of this pumping apparatusfliquid may be slowly and quietly drawn from a receptacle andout through a faucet. This-is an advantageous apparatus for drawing ale orA similary liquids which cannotl be properly lreptor drawn under pressure. Any desired quantity of liquid less than the capac-ityfof the space in thepump-cylinder between the extremities of the piston stroke may be drawn at one move of the faucethandle, as the flow may be stopped at any time by tilting the handle back, and greater quantities may bel pumped by alternately rocking the handle at the ends ofthe piston strokes.

Other modes of apply-ing the principle of my. invention may beemployed for the mode herein explained. Change may therefore be made as regards the mechanism thus disclosed, provided the principles of construcvlion set forth, respectively, in the following ing-passages foradmitting and exhausting the actuating fluid to reciprocate said pistons, of a faucet connected to the pump-cylinder and provided with a controlling-plug having a handle, a valve-casing formed with inlet and waste passages and having the fluiddistributing passages entering it, and a valve in said casing and connected to the plug to be actuated lby the same and constructed to connect the distributing-passages to the inlet or waste passages, substantially as set forth.

and a valve in said casing and connected to the plug to be actuated'by the same 4and constructed'to alternately connect each distributing-passage to the inlety and waste, substantially as set forth.

3. In apparatus for pumping liquids by fluid-pressure, the combination with a pumpcylinder, a motor-cylinder havinga distributing-passage at each end, and a piston in each of said cylinders and connected to `reciprocate one with the other, of a faucet connected to the pump-cylinder and provided vwith alcontrolling-plug having a handle, a

'one at each side of the inlet-port, anda valve sliding in the valve-casing and shaped to alternately connect the inlet-port with one distributing-port and to uncover the other distributing-port to the waste and connected to the plug-handle to be actuated by the same, substantially as set forth.

In testimony that I claim the foregoing to be my invention I have hereunto set my hand this 5th day of May, A. D. 1896.
