This invention relates to that class of 'faucets which are primarily designed for use in dispensing beverages from lountains or coolers,` faucets used fork this purpose .being usually of the reciprocating, self closing type. to wh1ch type of faucet the present invention is primarily intended :to be applied. f g

An important obfection toiaucetsfwhich have generally been usediorI this purpose is that after the valve isc-losed `and the il'low past the same has been cut oil, several :drops:

of the liquid dipensed Will drip tromV the discharge orifice, this being liable to occurV several minutes after the receptacle, into which the beverage was drawn,hasbeen removed, so that it has usually `been necessary to make some provision to receive the drip from the faucet, todo which is often.objectiomibley The object of my invention. is to provide a form of faucet which" lis especially adapted for dispensing purposes `and rwhich isV so constructed that, the instant the flow therethru has been cut olf, no drip of liquid therefrom Will occur.` y

I accomplishrthis object by construction hereinafter i described Vand as .il-

lustrated in the `accoliipanying drawing inwhich i i. i Y

Figs.. 1 and 2 are respectively, 4side. and front elevations of a-faucet embodying my Fig. 3 is a central vertical section `thereof at line 3 3 of Fig. 2;

Fig. 4 is a horizontal sectional view at line"l i-410i Fig. e. i i

Fig. 5 is bottom plan view of the discharge `end thereof. y

Fig. 6 is a sectional view similar toFig. 3 of a modified form of valve casing which l may employ.-

- Referring tothe construction of Figs.`

on the seat 15, said edge on thehead projects n very slightly beyond the bottom surface or to 5 the faucet casing comprises the horizontally extending inlet portion and the .vertically disposed cylindrical outlet-portion 7 having a cap 8 threaded in its upper end. A guide pin 9 is secured to the inner side of cap Sand dependstherefrom and a cylindricalflyshaped valve stem l0, having a central longitudinal bore 11, which receives said pin, isprovided, saidstem being adapted to slide freely on said guide pin, and, as the bore of the stem is closed'at its lower end, the fit of the stem on the pinis suliiciently loose to prevent the openingfand closing movement means Vof the from being retarded to any greater extent than may be desired. Thelower portion of the stem is provided with a cylindrically` Vshaped head 12, having an annular groove therein,.in which-an elastic valve washer 13 is arranged. the portionot thehead above the washer beingfo't a diameter `nearly equal to the diameter oi the washer. The end wall 14 at the lowerend of thecasingd extends obliquely downward toa circular centrally disposed discharge port, anda downwardly inclined val-ve seat 15 is formedon the inner or upperside of said .endwall which surrounds said-port. Thelower end portion ot the head 12 is-closely,`bnt` slid-ably litted in. said discharge port andthe washer 13 is arranged to .engage said seat loto close the passageway. "An annular flange 17 is formed on the upper portion of the stem 10'anda`. coiled spring 18 is arranged about theV guide pin 9 between the inner side of cap 8 and the upper f press the washer 13 against its seat. An operating lever-is provided for lifting` the valve from its seat which comprises a handlepor-H tion 20,ashatt portion 52,1which extends at right angles thereto and an arm portionfQZ, Vwhich extends at right angles to the -shaiit portion-the latter being extended through y apacked bearing 23 in one side of the supply pipe 6 and thel armportion extending beneath the iange 17, so that Vwhen thehandle' is pushed rearwardly thevalve willbe lifted from its seat.

Thelower end of the eylindrically.shaped that, when the valve, or washer 13, is resting the operating lever to suchan extent that the.

cylindrical head 12 will be completely withdrawn from the port at the lower end ofthe casing', so that the lower end ofsaidhead Will be above the seat 15, in which position the liquidwill be free to flow past the valveV4 andbe discharged through the porti and when thehandle is released, so that the spring? A9() head `12 has a recess .12 formed therein, said recess havinga concave bottom which meets the cylindrical surface of the side oi the head, `and forms a thin depending edge, so arranged 18 may act, the head will reenter the lafsing port and eut',v ell the llow before the valve aetually seats, the `.remainder oi' .the closing `movement` actingn to expel any liquid .which mighty remain within the port by reason of afpiilary attraction afterythe 'alve is seated. As the easingr surtaee or end 'all ll about the port converges downwardly to the edge o t the port, and as this surface will be dry, no liquid will run up thereonas itl will beprevented Jfrom so doing by gravity and capil- 'ary repulsion, so that the extreme outer, or lower end ofthe head ist-he only snrlaee to which the liquid 4can eling. A5 the lowest portion of the head is a sharp edge. drops ol1 liquid will not cling.r thereto. or, itthev tend to do so, they will he drawn into the avitjvv or receso l2 in the end olthe head. That is. an): dropS remaining|` on the lower end ol' the head will ber drawn Iinto the rei.l leit'her b v vat-num action. 'or capillariy attraetion. and to -be sustained thereinby atmospheric presure or eapillar;v attraction flor an indel'inite perioih as indieated in Fig. 3. Fo that the instant. the alve seats andthe flow is ent oti there will heno further drip trom the disc-hargeend o'l the 'faucet'.

ln the form ol my invention above de- .eeribed` it is necessary to remove .the ra p 8. and operatingr lever. to seeure aeeeaa to `the valve. so as to renew the. ialve. washer. Should it he neeessxary to do so. '.'ln the eonttruetion olI lfigr. (i the entireiqliper portion off the can ingr 25 in formed in one pie'ee and a removable lower end portion 2li is provided. having' a threaded'eonneetion wi tali Vthe upper portion. whirh. when removed, pern'iits` ready aecefzs to the valve washer. so that it maybe changed. The eonstruetion, so la 'as the means for preventing drippingr iS concerned, is the Sante as that already described. i
