PLUMBING FIXTURE FOR LAVATORIES.

Specication of Letters Patent.

Patented Sept. 24, 1907.

Application led March 2, 1906. Serial No. 303,780.

To all whom it mag/concern:

Be it known that I, ROBERTF. GILLIN, a citizen of the United States, residing in the city of New York, borough of Brooklyn, in the county of Kings and State 5 of New York, have invented a certain new and useiul Improvement in Plumbing Fixtures for Lavatories, of which the following is a specification.

AThe invention relates to means for controlling the supply of Water to hand-basins and analogous 'recep.

l() tacles, and its main object is to provide'the valves for the water-supply pipes with operating means which,

with the basin-cock, shall lie as nearly flush as practicable with the basin-slab and project so little above the upper face thereof as to permit the slab to be Aeasily 5 cleaned. Another object is to provide self-closing valves especially adapted, to be operated by means lying normolly nearly Hush with the slab and moved by dcpression therein, and a further object is to provide connections between such valve-casings and the basincocl; which shall be simple, inexpensive to manufacture-and constructed to permit easy installation 0i the apparatus with access to all portions for inspection, adjustment or renewal of parts.

The invention consists in certain novel features, details of construction,- and arrangement of parts vby which the above objects are attained, to be hereinafter described and pointed out in the claims. e,

The accompanying drawings forni a part of this speci- 0 ication and show an approved form oi the invention as applied to a hand-basin.

Figure l is a plan View of a. portion of a basin-slab equipped with the invention. Fig..2 is a vertical section on the line 2-2 in Fig. 1, partly in elevation. Fig. 3 is a vertical section through a portion oi the basin an slab, showing the basin-cock in elevation. Fig. 4 n, an elevation, partly`ii1 vertical section, showing one of the valve-stenisand its connected parts on a larger scale. 4 n

Similar letters of reference indicate the same parts in all the figures. A

A is the basin-slab, B the bowl and C the back-slab. The basin-slab has a central opening aior the basincock or spigot D and on one side an opening al for the 5 hot water valve and opposite thereto an opening al for the cold water. In each is a push-button by which its valve is opened to admit water to the cock. Both valves are alike and a description of one will sulllce,

E is the valve-casing having a downwardly projecting scat E sunounding a central opening e through which water is received from a chamber E2 connected by a union at E3 with the supply-pipe E4. into the *upper end of the casing is screwed acylinder F having a stuffing-box I"1 at its upper end.

G is a casing screwed upon and inclosing the cylinder F and extending through th opening al, terminating in a flat collar or flange Gl lying upon the upper face of the basin-slab and held to the latter by a nut Gf on the exterior oi the casing G beneath the slab. The interior mid-length portion of thedasing G is smoothly iinished toiorm a cylinder G3 and is provided with a stufling-boxv G4 in the diaphragm G5v forming the bottoni of the recess g in the upper end oi the casing G.

H is the main-valve, consisting of a disk of leather or analogous material supported in a shallow cup Hl of metal secured at the lower end oi the valve-stem I extending axially through the valve-casing E, cylinders F and G3 and their smiling-boxes and terminating in a push-button Il in the open upper end or recess g of the casing G. The stem I carries a piston I2 matching to the cylinderFand at a higherlevel :i similar piston l3 matching to the cylinder' 'lhc valve is opened by downward pressure on the button ll and closed automatically when released -by a spring .l inclosing the stem and abutting against the stuIling-box F and piston I3. Slow closing effected by the action o the pistons I2 and I3 inthe cylinders lr1 and G3, the lowerniost forming a Water-check and the uppermost an air-check, air being admitted through the aperture g1. At the lower end of the valve-stein is a con'e'I4 immediately above the main-Valve H, serving gradually'to reduce the area of the opening through the valve-seat as the valve closes and thus prevent hainmering or chattering. j

A tubular arm E5 extends laterally from the casing E above the lmain-valve and is either joined directly to a branch Ll on the shell L, or is connected thereto by a pipeE, as shown, to convey Water to the cock D. The latter is a flattened spout lying close to theslab and projecting over the edge oi the bowl. screw-threaded pipe D extending through the opening o and having a flat smoothly rounded fiange D`- lying upon the slab and ironrwhich the spout extends, A squared collar D3 on the pipe engages the-opening u and the whole is firmly held by a nut D4 on the exterior et@ the pipe Dl engaging the under face of the slab On the :lower end of this pipe is a tubular extension D5 of It forms part of a long as the valve is depressed-fand so much longer as is y required by the water pressure and the spring `to reseat the valve against the opposition of the Water-check at F and the air-check at Gf. The duration o this closing movement may be so conditioned by the force of the spring and resistance of the checks as to permit a sutiicient iiow to the bowl-for a usual supply by simply depressing the push-button and immediately re' leasing it. In any case the automatic action oi the valve v tends to prevent unnecessary waste of mater.

To prevent a continuous wasteful lbw due to holding the valvein the extremely depressed position by.the application of a Weight to the button or otherwise, an vauxiliary-valve-seat E is provided in'the'chamber Il2 and a second .Qr auxiliary-valve K i's'wapplied to the valve-stem below the main-valve H, the effect being to shut off the supply if the valvestem be :held down to the extreme limit of its motion. i'

The/construction avoids the objectionable projec- 'tions of the usual stop-cocks, bibs and controllingdevicesand permits a degreeloircletjnlinsss and neatncss of appearance not 'otherwise attainableA By disengaging the unions E3 and lopsening the nuts `G2 G2, D4 'and D the valves,"casings, and connections to the cock may be easily removed and examined, adjusted or repaired. I

The valve-stem with its valves and pistons are assembled andheld as shown in Fig. 4;:the straight-line arrangement affording simpleand economical construction`.

It will be noted that the pressure oi the water tends to seat the main-valve, thus lessening thedanger o leakage, and also that the' cylinders F and G3 of the water and air checks open downwardly thus permitting any water to escape and relieving the stuffing-boxes. The air check may be dispensed with if preferred, relying upon the water check alone to retard the closing movcfy ment, and the auxiliary-valve K and its seat El' may' also be omitted.
