VALVE DEVICE FOR PLUMBING FIXTURES.

APPLICATION FILED JAN. 15, 1907.

Patented Aug. 24, 1909.

smx 5 I r wiea m ransients; new, a cnrcaeo, IL'LINO'IS.

- a citizen of the United States, residing at claimed Chicago, in the county oilCook and State of Illinois, have invented certain'new anduse: ful Jmprovem'ents in-i} Valve Devices. for

. Plumbing-Fixtures, of which the following is aspec1fication..- 1 a The present invention relates more part1cular1y to a packing for valve stems of valve devices and I therefore do not claim in this application. the construction of the valve device whichlis shown, described and in my pending application, filed May 28,1906,- Serial No. 319,102.

The object of the invention is, to-provide an improved; packing, and, toLthisbend the I invention consists the features of novelty that are hereinafter described with-"reference to the accompanying drawing whichis'made a part of this specification;andiinfwhich:-

Figure '1 is an enlarged .verticaLlongitudi nal section of the'valv -'deyiceZL-' Fig. 2 is a vertical transversesection "thereof son the lme 3'-'3, Fig. 2.- Figs.f3 and 4 'arefaxial sections of 'the elasticpacking ring and its protecting-shield ;g.

In its general construction, arrangement "and mode of operation the valve-device of the present applicationdbiesinot difier from the'valvedevice of my aforesaid-patent.- .J

The' valve-device shown in fthe' drawings has' a fitting'a provldedfwiith three' branches,

. I one (A) leading from-i a souree of water supply, one (B) leading toa'fflushin tank, and one (C) leading to the bowl or opper through a valve-casmgC. Communication between the branches A and B is controlled by a spring seated valve D seating with the water pressure and communication between the branch G and the bowl is controlled by a valve E which seats against the water pressure, in opposition 'to the force of an unseating spring F when pressure is applied to its stem G by a seat connection H. The casing C, which contains the valve E, passes through an opening through the'back of the bowl on other'fixture and is providedwith openings 0 (one of which is indicated by dotted lines) which open into the hollow rim of the bowl. On the inside of the bowl exterior for the receiving of a nutil which is adapted to bear against the back of the p cification oi Let ters Patent. arp'li tion dreamer, 15,19 9. seri l no. 352,419,

by the back. wall of the bowl is'clamped be- C' firmly held in place. The seat J for the ValveE is formed on the end of a tube threaded on its exterior and'screwed into K which guides the valve stem G and against which the spring F reacts iii-one .direction. It reacts in the other direction against the valve itself, o'r-a shoulder on the valvestem, and 'hold'sthe valve normally unseated. The seat-for the valve E andthe rled by the casing 0' makes the mechanism may. be handled freely without dislodgin any of its parts, and permits the casingC and fitting a to'be separated without' releasing the tension of the spring F. A further greatly facilitates adjusting the valverelatively'to thefvalvefseat. This may be done before-the fitting is coupled ,to the valve casing by the application of a suitable tool With the construction shown in my ormer berepeate(lly;cpupled and uncoupled before the proper adjustmentis reached. This is :because the. valve is carried by the casing and its seat by the fitting; v a

The .casing 'and' fitting are secured together by a union coupling L which is pref threaded engagement with thecasing. -The fitting has a. neckM which is surrounded by tube or sleeve N is screwed into the branch Wlthfl. radial flange at providing a shoulder '-which engages the shoulder on the interior of the coupling. This'sleeve carries a spider O which guides-the stem 0! of the valve D. It will be understood, of course, that the extremities of the stems (l and G; are in contact, or practically so, so that. in opera-' tion they engage each other with practically no lost motion.

"The stem G- of the outlet valve it passes. through an opening in the casing'C and extends into the bowl in sition to be engaged by the seat connection 1-2 that when the seat is depressed the stems G and d will be forced .Tatentednug. 24;, i90 9-r i l L-bowl aiid draw the casing backward, where- Be it known that.

tween the nut I and flan e '0' and the casing the casing 0- so. as to be adj'listably carried"- thereby, and the tube carries also a'spider s' ider for the valve stem G being both ca'r ofisaid valve a self-contained device that and very important advantage is that it tothe rear end of the tube J to facilitate" which the tube is provided'wlth -lu s J pate1it,"the casing and fittingm'ay have to Y erably swiveled to the fittingvand has 95, the reduced portion of the coupling and a.

C, the sleeve being provided at its outer end llO j I, ing through which the valve-stem G passw. The .frust-um tapers to a feather edge so to which it would be subjectedb Y the valve found that such a packing is easily injured in the rearward thus seating the valve E and unseating the valve D, and when the seat is released the reverse action will take place, under the influence of the springs. The joint between the stems G and the Walls of the opening through the front end wall of the casing through which it passes is made tight by 'an elastic packing P, located within the casing, which has a portion 12 in the formof a frustum and a portion p in the form of a radial flan e at the base of the frustum the frustum being provided with an openthat the pressure of the water surrounding it tends to press it tightly against the valve stem and prevent leakage past it. It is unless it is protected and this is particularly true if it is used in the position shown in the drawing because of the repeated blows E. To revent its being injured, a shield orm of a complementary -hollow metallic frustum Q, is interposed between it and. the valve '13 the base .flange g of the metallic frustum resting upon the base flange of the elastic fru'stum'. The elastic packing serves also to cushion the stroke of the valve and-lessen the noise incident to the operation'of the valve. .Furthermore the shield completely covers and conceals;- the elastic frustum', the opening through the shield being just sufficient to .receive the valve stem so that when the valveis bearing against the hollow frustum, the pressure 0 the latter upon the elastic frustum serves to compress it and thereby more firmly force it against the-stein G. t

The radial flange of the elastic "packing fits the valve casing tightly so that it Cannot slide therein as the valve stem moves back and forth and the elastic packing fits the f v valve-stem tightly so that the "alvestem cannot slide relatively to the packing. As a result of these two tight fits, as the valve stem moves inward the central portion of the elastic packing will move inward with 'the valve stem and the face of the elastic packing will bulge, assuming a concave. The inward movement of the valve stem is so slight as'to permit this action of the elastic packing. The result of it is that there is no sliding friction between either the valve stem or the casin and the elasticackin and in addition to t is it makes an a solute y watertight joint between the casing and the packin The mounting of the adjustable valve-seattube directly upon that part of the casin which carries the valve and the mounting o the spider, for guiding the valve-stem, upon the valve-seat-tube are'not claimed in this a )plication, being part of the subject matter oi my coending application filed May 28th, 1906, erial No. 319,102.

What I claim as new is:.

In a valve-device, the combination of a valve-casin a valve within the casing, a stem exten ing through. the end of the easingand carrying the valve and an elastic packing located within the casin and surrounding the stem, with a tight fit, between v the end of the-casing and the valve, said packing having a portion in the form of a frustum and a portion in the 'form of a flange radiating from the base of the frustum and, at its periphery, engagin the easing with a tight fit, whereby sli ing friction between the valve-stem and packing and between the valve casing and packing is prevented.
