This invention relates tov liquid-dispensing faucets. It is anzobject of theinvention to provide a simple and eiiicient faucet, capable of lconvenient and reliable operation, tofpermit- `at will ay measuredv intermittent or a continuous liquid discharge.

A further object is to' providezan improved faucet' of the vcharacter mentioned 'having features of functional advantage and structural' superiority, as vwill in part be noted heroine ter in connection with the tollowing` description of'the accompanying' drawing,

which illustrates a preferred embodiment of the invention 'andV in which Figure 1 is a vertical sectional view through the faucet in closed position, and

F ig. 2 is an elevational view at rightangles to1 Fig. 1.

Referrin'ginore particularly to the drawing,.the faucet includes a casing 1 having 'anI inlet 2, a discharge opening 3 (closable by valve 4),l a'measuri-ng chamber 5 with an inlet 6 (closableby valve 7) and an operating handle 8' to governi the 'positions ofthe valves 4 and 7, as will be described. i

The casing 1 is preferably tubular, and conveniently has a dividing wall 9, which is' provided with the opening` 6. in orderto close the casing` at its lower end a dished bottom member 10 may be utilized, it being observed that this member is formed with `the discharge opening' 3, and that packing, such as 11, may be employed in order to `assure a fluid-tight seal.- Likewise, the upper end of the casing may carry a cover 12, conveniently secured in position by screwthreads, a disk 13 of suitable material being employed in order to assure a sealing of the parts. l

The valve 4 may be removably attached to the lower end of an operating stem 14, which may be tubular, or atleast provided with a passage 15 Y(indicated in dotted lines) erlitt/enclino,V from a'portion somewhat below the `casing wall 9 to the portion well within the upper end of the casing 1, which, as will appear, constitutes an air chamber' 16. They fsEvn-NTY PER CENT 'ro tent lesstha-n the endl 17.V The stem 18 above i the valve 7 also carriesv a disk piston 20. Valve 4 is centered at the lowerfend bysuitable means, such as guidinglprongs 21', carried thereby. The-stem 18 is' also providedr` vwith anaopening 15shown 'out of registry with they upper opening of the passage-15 ofthe stem y14, but, as will appear, capable .of registry with thelatter under certain conditions of operationA to open communication' from the a-irchamber v16 through the passage linto the measuring chamber 5 and allow flow ofthe vcont-finned liquid in the latter throughthe discharge opening 3'., i v

Valve 7 is normally urged toward closing position by a coil spring/22 which surroundsthe stem 18 and re-acts between the cover'12 and the piston top 20, while valve14 is likewise normally urged towards closingposition by a coil? spring- 23 located in measuring chamber aand re-acting between theY dividingv walll 9 of the casing andv the lower guide member 21. The position of the twov valves, however, is governed byconnectionsbetween `the' ends 17 and 19,of the stems 14 and 18: with the operating ,handle 8, and for this jlliurpose the handle at its lower end is bifurin addition'. are irovided with-aV iair of vi'egi-stering uppercam slots 27 and a pair of lower registering camslots .28, asshown' in Fig.. 1, while'the upper rextremity ofthe .valve stein 14 carriesl a cross Vpinl 29"havin,f

its ends withinthe slots 27, and ltheupper extremity of the stem' 18 carries pins 30, having their extremities in the slots28. Itwill be apparent thatas' they handle 8 is rotated about its'pivotal .axis 26, vertical movement of the stems 14 and 18 (with the valves 4 and 7 thereof) withrelationto each other and to the casing' 1, in accordance with the shape of the slots 27 f and 28. r

`The operation of the'. faucet will now described. If the operating` handle 8 is.rotated Yto the right (Fig.v 1), the stem 18 remains u'nrnoved, since'thepins 8O traverse a portion of the cam slot 28 on the arc of a will beV brought about circle, having 'its center at the axis26of the operating handle.k Valve 7 consequently remainsopen. During this movement, however, stem 14 israised by the pins 29 traversing the left portion of the cam slots 27 (as viewed in Fig. l). Therefore valve 4 vis raised and a clear passage opened from the faucet inlet 2 through the opening 3 to permit a continuous flow ofliquid from the faucet. 8 to upright position restores the parts to position shown, and stops the liquid flow. ln this position it will be observed that the chamber 5 andthe chamber above the dividing Wall 9 and'beloiv the piston 20 are filled with the liquid fromthe source to which the inlet 2 is connected,

When, now, the operating handle 8 is rotated to the left (Fig. 1), stein 18 is first depressed to cause valve 7 to seat in the opening G and close communication from the inlet 2 to the chamber 5. Valve stem 14, during such movement of the operating handle, is not disturbed, but immediately thereafter valve 4 is raised, while valve 7 continues to be closed, and consequently the discharge opening 3 is cleared to permit lloiv only of `the contents of the chamber, 5. which has conveniently a. predetermined measured amount, for example, one ounce. Discharge of the liquid from the chamber 5 is further facilitated by reason of the registry at this time of the opening 15 in stem 18 with the upper end of the passage 15 in stein 14, so

that lthe liquid, as discharged is displaced by air from the chamber 16; the latter being in communication with atmosphere by an opening 31. Reverse movement of the operating handle, as will be apparent, serves first to close the valve 4, and subsequently open valve 7 to the position of parts shown inthe figure.

It is apparent, from `the foregoing, that the improved device is capable of convenient operation to deliver'at will either a definite measured amount or a continuous flow. On this g account `the faucet is particularly adapted for use in connection with beverage delivery, for example, with concentrated syrups or liquids which customarilyare mixed before drinking. On account of the location of the discharge opening 3 and the (io-operating shape of the valve 4, it will be apparent that theY faucet is substantially dripless. Also it lis to be noted that as the various pinsy 29, 26 and 30 may be removable the parts of the faucet may be readily disassembled and removed for thorough quick cleaning. The device as a. whole is of con ventional and attractive shape. The parts I are capable of economical manufacture` and vnot likely in service.V

to get out of order or deteriorate It is to be understood,moreover, that cer- The reverse movement of the handle i projecting without said casing,

tain features of the invention, as above deteiided scope ofthefollowing claims.

Having described my invention, what I,l

now claim is new and desire to secure by Letters Patent is: f

1. In a dispensing faucet, in combination,

a valve casing having a measuring chamber and provided with inlet and outlet openings, independently` movable valves for said openings, contiguous stems for said valves operating means to effect the independent or joint closing and opening of said valves, and means whereby, when said inlet valve is closed and said outlet valve is opened, said measuring chamber is placed in communication from above with the atmosphere.

2. In a dispensing faucet, in combination, a tubular valve casing having a lower measuring chamber provided with an inlet at its` upper end and an outlet at its lower end, independently movable valves for said inlet and said outlet, a vertical stem for said outlet valve extending upward axially through andbeyond said casing, a tubular stem for said inlet valve enclosing said stem of said outlet valve and projecting a lesser distance than the latter beyond said casing, Van op- Verating membervsupported without said casing, and connections, including cam means, between said member and said stems respec tively, whereby movement of said member in one direction serves to eifect continuous y liquid flow through said measuring chamber and movement in the other direction serves te discharge only intermittent, 'measured liquid quantities. f

3. In a dispensing faucet, in combination,

a valve casing having a measuring chamber provided with aninlet and outlet, independently movable valves for said inlet and said outlet, both normally spring-pressed toward closed position, stems .for said valves extending through and without said casing, and a yrotatable operating member having operative connection with said stems without said casing whereby movement of said member in one direction holds said inlet valve open and opens said outlet valve, and movement in the otherdiiection from said intermediate position first closes said inlet valve wliile'maintaining said outlet valve closed and then opens said outlet valve while maintaining said inlet valve closed..

1n testimony whereof l affix my` signature.
