' which the following is a specification.

This invention relates to Systems whereby beer and other liquids may be drawn off from a supply thereof in a definite quantlty eachtime the system isopened for delivery, this being accomplished by providing a cylinder-in a circuitconductor and a piston in the cylinder, together with a faucet or controlling meanswhich, as it is successively operated to open the ystem for delivery,

switches the flow fromthe supply into the circuit conductor alternately at, opposite sides of the piston. The inventionconslsts, first, in a novel construction of parts for controlling vthe flow. into the circuit conductor at alternately opposite sides of the piston and, second, in anovelconstructmn of a piston andcooperating elements 1n such In the accompan'yirw drawings, p Figure 1" is a plan 0 a dispensing system of the kind indicated and including'my improvements; V i a 1 F Fig. 2 is a. planshowing certain parts enlarged and partly in section;

' Fig. 3 is a front elevation of thefaucet of the controlling means, partly in section;

Fig. & is a horizontal sectional fragmentary view of. one of the valve devlces and adjoining partsof the controlling means;

Fig. 5 is a longitudinal .vertical sectlonal view of the controlling means; and, p

Figs. 6 and .7 show the piston in side elevation (partly insection) and in end ele vation.

' a is a circuit conductor including a t ne-1 der 6 inxwhich is arranged apiston c. d. is

a barrel or other source of'supply for the liquid to be dispensed'and e a pipe leading therefrom. f is a faucet to which theends of the circuit conductor a'and-the p pe '6 are connected as hereinafter. explained. q

- The faucet body comprises two parts g and h. The party has "a screw'plug twhereby it may be fastened to asuita'ble support, as j, and itji s provided with a'central port and twolateral ports g,the port g being connected to the pipe 6 and the ports 9 to the ends of the circuit conductor a.

The part it of the faucet includes the hollow faucet body 70 formed at the back with a receivingchamber Z, open rearwardly, and at the front with 'a delivery chamber m whose outlet is the spout n. Said body also includes passages 0 which lead from the rear thereof forwardly, being extended .as to their front portions between the chambers Z and The parts 9 and k may be secured together by screws or the like 7), whereupon the port 9 discharges into the chamberl and the ports g register with the passages 0, g tand 0 in eachflcas'e forming in effecto a terminal of the c1rcu1t conductor'a. In the wall p which separates each passage o'from thebhamberl is tapped a threaded hole 9 and through the wall r Whichseparates said passage from the chamber m'is drilled a plain hole 8.

Into ach threaded hole' 9 is screwed a bushing t; whose reduced portion a fits the corresponding hole s, compressible washers o being interposed between each wall. 79 and 'rand a suitable shoulder on thebushing t to afford a tight joint. The bushinghas one or more transverseopenings w'whlch register with-the passage o, audit is has an axial bore which afiordsat one end a port as lead ing to the chamberljand at theother end a port y leading to the chamber m. I In the bore of the bushing slides a valve device consisting of a stem 2 having longitudinal and radial guiding ribs, as shown in Fig. 4, and a fixed head or valveEZ at ,one end and a removablehead or valve 3'screwed thereon atthe other end, 4 being washers bearing against the. inner sides of said heads and adapted to bear against the valve seats formed by, thev corresponding ends of the bushing." The valve devices are normally heldwith their valves or heads 2 bearing against their v'alve seats by spiral springs 5 interposed between them and the back'of the chamber Z.

For alternately opening' the valves pro videthe vertical spindle 6 having a handle 7*at its upper end and journaled inthe bot tornwall ofthe faucet and in a gland its upper w'allfi This spindle penetrates the chamber min" the vertical central plane of. the faucet andit is equipped" with two .oppo-' site cams or lugs9 arranged in different horizontal planes and adapted, when the spindle is turned, respectively to bear against the correspondingly arranged ends of levers fulcrumed in chamber m on the studs 11 and each preferably containing a spring-pressed plug IQbacked by an adjust-- ing screw 13 tapped into the lever (Fig. l).

The construction ,ofthe piston c is as-follows: The piston body 1d has alined recesses 15 formed in its opposite faces and eachreceiving a spring 16 and a rubber valve 17 kept assembled with the piston by a disk 18 having a central thimble 19 which is screwed into the recess 15 and has its outer end re duced to limit the springpressed movement of the valve l7, said disk holding in place a pliable cup-shaped washer 19 adapted to form a seal as between the periphery of the piston and the cylinder b.- Connections between the ends ofthe cylinder and the pipe portions'of the circuit conductor aarezan forded by nipples 20 which project into the cylinder and thus afl'ord seats for the valves 17. r

Operation: The usual position for the spindle is that indicated in Fig. 3, where its handle stands as shown in' full lines in said figure; A; half turn or the spindle results in flow ofthe liquid always for thedelivery of a definite quantity, thus: In the stated position or" the spindle one valve device opens communication between chamber] and one of the passages o and closes communication between said passage and chamber m, the conditions being reversed as to the other valve device with respect to the corresponding passage and saidchambers; Admission ofj'liquid by one valve device into the circuit conductorat one side of the piston results in the liquid at-the opposite side thereof being displaced to cause delivery past the other valve device, through chamber m and so on out at its nozzle it, until the piston reaches the endof its movement,

7 by contact withnip'pleQO, and seals escape of liquid past the piston and through said nipple, by such contact and the expansion of the-washer at the pressure side of the pistonfl The spindle may be turned 90Tfrom the position abovereferred to, when the faucet is not in service; in this position both'valve devices will be heldin their closedpositions by their springs, insuring against leakage even should there be leakage atthe piston.

One of the important features army invention is the employment of thrustwise mov able valve fdevices, preferablyarranged ]as shown,- whereby leakage is less likely to occurthan in faucets usually employed for this purpose having four-Way rotating cocks and the like, and it it does occur may be readily stopped by the simple expedient of fitting in fresh washers n Having thus fully described my invention, what I'claim as new and'desire to se cure by Letters Patent is 1,. A faucet comprising a body structure having a receiving chamber and a delivery chamber; said structure-having separated passages each communicating with both chambers and being one of. the terminals of a circuit-conductor to which the faucet is to be attached, and valve devices, each appertaining to a passage and controlling the communications between the same and said chambers and beingmovable in one direction 'to open one and close the otherotsaid communications and in the opposite direction to-close the first-named. and open the otherofsaid communications,

2. A faucet comprising a body structure having a receiving chamber and a delivery chamber, said structure having separated passages each extending between and com municating with both chambers and being one ofthe terminals of a circuit-conductor to which thefaueet is to be attached, and valve devices, each appertainingto a pas sage and controlling the communications between the same and. said, chambers and being movable in one direction to open one and close the other of said cominunications and in the-opposite'direction to close the first namedjand open; the other of said co nmunications. p

3. A faucet comprising a body structure having a "receiving chamber and a delivery chamber, said structure having separated passages each communicating with both chambers and 'being one ofthe terminals-of a circuit-conductor towhich the faucet is to be attached, and valve devices thrustwise movable in said structure, each appertaining to a passage andrcontrolling the communications betweenjthe same and said chains hers, and means to move said devices in opposite directions, each device when so moved opening one and Jclosingthe other of the communications controlled thereby.

i, A reversible-circuit fluid. conducting apparatus including a supply means, delivery means, acircuit conductor having at each end a pairoitopposite ports, one port in each pair communicating with the supply means and the other with the delivery means, and a pair of ,valve devices respec tively controlling the pairs of ports, each. valve device being movable in one direction to open the one andlclose the other ofthe corresponding ports and :iii the other direc tion' to dose :the first-named port and openthe other: i r l A I i 'i I 5, A reversible-circuit fluid conducting apparatus including a supply means, a deliyerymeans, a ciricuit conductorhaving at each end a pair of opposite ports, one port in each pair communicatmgwith the sup its ply means and the other with the delivery means, a pair of valve devices respectively controlling the pairs of ports, and means to move said devices in opposite directions, each device when so moved opening one and closing the other of the ports controlled thereby. f

6. A. reversible-circuit fluid conducting apparatus including a supply means, a delivery means, a circuit conductor, a pair of spring actuated valve-means for switching the ends of said conductor alternately into 1 communication with the supply and delivery means, and a rotary manually actuated camming actuator for said valve means.

7. A reversible-circuit fluid conductingof its limits of movement, and a common means to move said valve means alternately against the pressure of the elastic means.

In testimony whereof I aflix my signature.
