.valve member 34 radial arm 38 depending from a transversely disposed rocker spindle 39 which extends through, and is journaled in, a bearing provided in nozzle section Il above lining member 29, the latter and nozzle section Il being formed, respectively, with longitudinal slots 4U and 4l to accommodate said arm and permit of swinging movement of the latter.

At its one end the rocker spindle 39 is provided with'an upstanding handle 42 whose hub is provided with a laterally projecting stud 43 occupying a socket or groove 44 provided upon the outside of nozzle section Il and whose outer end wall serves as a stop to limit the movement of arm 42 toward the refrigerator.

When the handle 42 is swung in ythe opposite direction to effect delivery of the beerior the like, the spindle 39 is rocked in a direction to cause the arm 38 to engage the boss 31 and open valve 34, movement of the valve in this direction being limited by the engagement of its inner end with the longitudinally disposed end portion 45 of spring 35.

When the handle 42 is swung toward the left, Fig. 1, the pressure of the beer, supplemented 'by the pressure of spring 35, acts to quickly thrust the valve endwise into position against its seat 32.

As shown in Fig. 4 the nozzle section Il is made with two alined ports 46 and 41, one below and the other above the spindle 39, the said port 46 communicating with the interior of lining member 29 and the port 41 communicating with the outside atmosphere. These two ports cooperate with a -port 43 formed dametrcally through the spindle 39 to vent the upper end portion of the interior of said lining member when the valve is closed and the handle 42 occupies its full line position shown in Fig. 1. When the handle 42 is swung downwardly into the position indicated by dotted lines in Fig. 1, the opposite ends of the port 48 are out of register with the ports 45 and 41 so that the upper end p0rtion of the interior of lining member 29 is not vented while making a delivery.

The arm 38 is made with a cylindrical shank occupying a socket or hole 49 formed transversely through spindle 39 and said shank is xedly clamped within said socket by means of a screw 50.

The end of spindle 39 opposite the handle 42 is formed with a threaded countersink into which is screwed the threaded shank of a capstan screw 52 between whose head and nozzle section I I is compressed a spring washer 53 which may be made after the fashion of a lock washer. The head of screw 50 is disposed within the countersink 5l and its threadedv shank occupies a tapped hole at the bottom of the countersink 5I.

The vent conduit 45-48-41 which is closed while making a delivery and automatically opened when the parts are permitted to return to their normal positions, provides a quick draining feature which avoids dripping after delivery and tends to maintain that portion of the interior of the faucet that is outside of valve member 34 sanitarily dry while not in use.

The elongate Valve member 34 is, as shown in Figs. 2 and 3, made from a length of metal tubing having its opposite ends closed by plugs which are tted within the ends of the tubing so as to provide leak-tight joints. Thus the is circular or cylindrical throughout the greater portion of its length. The plug 54 at the outer end of the valve member is made parti-spherical so as to impart a streamline form, which avoids agitation and which properly engages its seat 32. 'I'he boss 31 is formed upon the plug 54. I

The valve member 34 is slidably supported centrally within the cylindrical chamber 21 by means of a plurality of bosses 55 projecting from the intermediate cylindrical tubular portion of the Valve member. The body of the valve member is made predeterminedly less in diameter than the `chamber 21 and is maintained concentric with the latter by the bosses 55. In practice I make the chamber 21 .725 of an inch ln diameter While the outside diameter of the valve member 34 is made .705, .700 or .695 of an inch in diameter according -to the pressure under which the beer or the like is delivered into the chamber 21 through the inlet port I9. This provides a flow-retarding constriction within the faucet and surrounding the valve member 34 which, together with the streamline form of the outer end of the valve member, avoids excessive foam. Furthermore, it will be observed that the valve lmember serves as a pressure-reducing valve because of the elongate constricted passageway provided between said member `and the surrounding wall of chamber 21. Also-the valve centralizing bosses 55 insure proper cooperation between the valve member and its seat at all times and prevent any lateral displacement or uttering of the valve.

Apparatus, such as the above described, are at times cleaned out and this is usually accomplished by connecting the delivery end of nozzle section l l with a supply of cleansing liquid under pressure or head so that said cleansing liquid is forced reversely through the faucet and the tube I6 connected therewith. Therefore, in order to prevent the Valve member 34 from seating against the rear or inner Wall of chamber 21 one end of the spring 35 is bent so as to extend longitudinally toward the valve member as at 45 which provides a stop which prevents the valve member from closing chamber 21 at its inner end when the cleansing fluid is forced into the faucet as described.

What I claim is:

1. A faucet of the character described comprising a body made with a delivery conduit including an elongate valve chamber of relatively large cross-sectional area and into one end of which beer or the like is supplied under pressure; an outlet por-t at the opposite end of said chamber; a valve seat Within said chamber surrounding said outlet port; an elongate valve member disposed wholly within said delivery conduit and made upon its exterior with bosses by which it is slidably supported independently and centrally within said chamber bythe portion of said body surrounding said chamber so that' it is movable longitudinally toward and from said seat and normally urged independently endwise against the latter by the pressure of the beer or the like to close saidvoutlet por-t, the cross-sectional area of said valve member being predeterminedly less than the cross-sectional area of said chamber thereby to provide an elongateconstricted pressure-reducing passageway through which the beer or the like is forced from the inlet end of said chamber -to said outlet port when said valve member is shifted longitudinally away from said seat, and a rocker spindleindependently supported by said body and provided with a radial arm projecting into said conduit so that it is 'operable to adjust 'said 'valve' member axially away from said seat byabuttin'gengagement with one end of said valve member thereby to open said outlet port when said spindle is rocked in one direction, said rocker spindle being provided with a handle disposed outside of said body by means of which it is operated.

2. A faucet of the character described constructed in accordance with claim 1 and wherein saidl elongate valve member comprises a body portion consisting of a length of thin metal tubing and two plugs closing the opposite ends of said metal tubing so as to exclude liquid from the interior of the latter, and wherein said length of metal tubing is molded to provide said bosses upon its exterior by which the valve member is slidably supported centrally within said valve chamber.

3. A faucet of the character described constructed in accordance with claim 1 and wherein said body comprises a tubular shank section, a tubular nozzle section whereof one end is telescopically engaged with one end of said shank section, and a coupling member rigidly fastening said sections together, and wherein a gasket of resilient material is confined in position between said two sections so as to provide said outlet port and said seat.

4. A faucet of the character described constructed in accordance with claim 1 and wherein said body comprises a tubular shank section, a tubular nozzle section whereof one end is telescopically engaged with one end of said shank section, and a coupling member rigidly fastening'said sections together, and wherein a gasket annulus of resilient material is conned in position between said two sections so as to provide said outlet port and seat, said gasket annulus being tightly clamped between the two sections of the body and serving not only to close the adjacent joints between said parts but also as a yielding seat for the elongate valve member.
