SELF-CLOSING FAUCET.

T0 all wtom lifmag/ concern.'

`Be it known that. I, JOHN. Sciarra), 4a

citizen of the United States, residing atl Cleveland, in the county of VCuyahogaV and State of Ohio, have invented a certain'new and usefulV Improvement in Self-Closing Faucets, of whichthe following `is a full, clear, and exact description; 1

This invention relates to self-closingfaucets; and is in the nature of an improvement on ithe faucet which is shown and described in theRice Patent No. 804,673,l The construct-ion'shown inthat patent is practically eflicient; but,`Y after ity has lbeen in use 'for some time, they valve, in closing frequently goes avainstits seatwith a thump ;f and likewise tlie valve frequently chatters before it Y Theobject ofzthisl invention is to provide a faucet v of' the generalA character shown in the above mentioned patent,-.but which is soA constructed `that the valve :will Vvalways goV noiselessly to its seat Without any thump or chattering. Y i

To that, .end .the invention consists in the construction and combination ofparts shown in thel drawings and pointed o ut definitelyY in the appended claims.

, In this central chamber 12, a water dis'- I tributing plugV 15 is fitted. VAdjacent its lower end this f plugv is-of slightly reduced f diameter, thereby leavingthe annular downwardly faced flange 15a-which rests upon the shoulder 12, there being the'packfin .ring 16 interposed-between these-"two sur aces;v A cap 181is screwed down into the open upper end ofthe chamberA 12 to close the same; and it engages the upper end of the plug and forces itvdown whereby the watertight joint is formed between the surfaces-12a'and-15e 4 with' thezaid ofsaid packing. ring 16. Thewater distributing plug 15fhas acelb trally placed cylindrical hole 15b extending through it from frtop` to bottom. It has, an f annular valve `seat 15d on its lower lend around this hole. Thishole isenlarged; at

`its upperend to form a recessl" inwhich packing 17 is placed.. Packing ringsv v19 restl upon-theV topl of they pluglland uponfthepacking insaidv recess; and `it is againstithe upper of 'these packing rings'thatthe llower end of the screw cap 18 directly-engages.

-. A portion of the outer'partl of this .plug is aoV cut away clear to the-central hole 15?,1'as/at 1 15C, vwhereby a water vpassageway is formed and this cuty awayy portion'. is so :located that i the produced` water passageway is .in lcom munication with theV 'outlet 14; wherefore any waterwhich ycomesinto the inlet. 13, andy goes up throughV the hole 1,5"y will pass through this water. passageway tof thenoutlet 14. AV cylindrical ,valve steml 20- passes Y throughV the hole 15P in this water distribut-y ingplugfrom top to bottom, and has anice sliding fit therein. f AIvalve -disk 213is fixed Y v d Y `to the lower end V.ofthis valvefstem for-fen-v gagement with lthe valve seat. 15d; This .valve stem is formed with awaterpass'ageway 20a, Ythe lowerfinlet end yofwhichv is at a distance of-l approximately: ioney quarter* of an` inch-above `thegv'alve disk;v and .itsdisf chargevendis at a pointsuchthat it'will communicate with the "water'pass'ag'e forn'ied` ioobythecutting'awa'y of the plugat 15 as,

has 4vgiventhe most practical satisfaction this waterl passageway v. 2()a 4is groove v'cut-spirallyn inthe external surface: of; the rvalve; stempas shown ingFigs:v 1, 3, f1 and-5.171. j. i

` above explained'.."Inthe,construction'whichl But the device will operate satisfactorily if the valve stem be constructed as shown in Fig. 7. As therein shown the water passageway consists of a longitudinal hole 20h, formed in the valve stem and provided with a lateral inlet 20e placed at about the same distance above specified above the valve 21, and a lateral outlet 2Od so placed that it will communicate with said water passage around the plug when the valve is opened.

To cause water to flow through this faucet the valve stem is pushed down, by means which will be presently explained; or some other suitable means; and it is pushed down far enough to uncover the lower inlet end of the water passageway carried by the valve stein. So long as the valve is so held down, water will iiow into said water passageway from below the plug, and will be discharged into ythe water passageway around the plug, and thence to the outlet lll. When the pressure holding-the valve open, as stated, has been released the water pressure below the valve will force said valve upward. There can be no lateral movement of the valve because the stem thereof has a nice sliding fit in the hole in the plug. Vhen the valve 21 comes to within approximately one quarter of an inch of they valve seat 15d, the lower end of the water-passageway carried by the valve stem will be substantially closed by the wall of the hole through the plug l5.' Then the valve will slowly move upward the remaining distance until it seats itself noiselessly and without any possibility of chattering against the valve seat 15d.

The means shown for pushing this valve stem downward consists of a stem 24 which is rotatably itted in a hole in the top of the cap 18,"and it has a handle 26 secured to its upper end. Gn its lower end, within a recess 18a in the lower end of the cap, this stem is lprovided with a laterally extended head 25 having oppositely inclined upper faces 25a, which will. engage with correspondingly inclined surfaces 18h carried by thecap within this recess 18% Therefore, by turning this operating stem 24C, it -will be caused to move downward. 1t is always in engagement with the upper end of the valve stem,

and will therefore cause the valve stem to move downwardv with the results above pointed out.

Having described my invention, I claim l. A self-closing faucet having a vertical chamber which is provided with an inletl valve seat on its lower end, a vertical valve stem which is nicely litted to and is slidable within the verticalV hole in said plug and extending both above and below the same, and having on its lower end a valve for engagement with said valve seat,-and said stem being provided with a water passage which at its upper end is in communication with the lateral water passage in the plug and which at its lower end terminates in a part of the surface of said valve stein, which is l such a distance above the valve that it may be uncovered by the downward movement of the valve from its seat, but which will pass wholly within said hole and be entirely covered so as to stop the entry of water into the same before the valve in closing comes ber adjacent the outlet from `said chamber,`

a cylindrical valve stein which is nicely fitted to and is slidable in the hole in said plug and which has an external spiral groove which extends from a point Aa short distance above the valve such that as the valve is closing this lower end will pass wholly into the hole in the plug vand be closed thereby before the valve reaches its seat to a point where it will communicate with the lateral water passage of the plug when the valve stein. has been pushed down far enough to uncover the lower end of said groove, a valve disk fixed to the lower end of said valve stem, and means to force said valve stem downward.

` 3. A self-closing faucet having a vertical chamber which is provided with an inlet above and below theoutlet therefrom and Y having a valve seat atits lower end, a vertical hole through it from top to bottom'which hole is enlarged at its upper end for the re-V ception of packing and said plugalso having a lateral water passage leading ffrom "said hole to said chamber adjacent the out-k let therefrom, a valve' stem slidably iitted in the hole in said plug and having onfits lower end a valve forvthe engagement of said valve seat and said stem being provided with a water passage which terminates at its lower end a slight distance above the valve and atjits upper endat a point where it will communicate with the lateral water passage in the plug when the valve stern has been pushed downward far enough toy uncover the lower end of said water passage, packing in the enlarged recess in theupper` end of said p1ug,' a metal acking ring on top of said plug and extending over said packing, a cap which screws into the upper end of said chamber and bears upon the packing signature.
