FAUCET.

To all whom it magi/concern.'

Be it known that I, WILLIAM T. TAGGART,

Aa citizen of the United States,'resi-ding at which it appertains to make and use the same.

This invention relates to improvements in faucets and more particularly to faucets so constructed as to enable the main valve to be removed without necessitating shutting off of the water.

The object of the invention is to provide a faucet of this character so constructed that ready access may be had to the main valve without either removing the faucet or cutting off the water supply inthe main pipe.

With this and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings z-Figure 1 represents a vertical longitudinal section Aof a faucet constructed in accordance with this invention with the main valve shown closed and the auxiliaryvalveopen; Fig. 2 is a `similar view with-parts broken off showing the main valve open and the auxiliary valve partially closed; Fig. 3 represents a side elevation partly in section with the main valveshown removedand the auxiliary valve closed. l

In the embodiment illustrated a faucet-is shown, the body or shell 1 of which is preferably cast in one piece and is provided with the usual inlet 2 and an' outet .3, the latter being in the form of a downturned spout as is usual in faucets of this character, and.

the inner ends of said inlet and outlet being offset vertically from 'each other with a chamber 4 formed between them. This chamber 4 lhas aconcave or rounded bottom 5 and is provided at its upper end or at a point diametrically opposite said bottom with an internally 'threaded opening 6 which communicates with the outlet and with a tubular extension 7 which pro]ects laterally Specification of Letters Patent.

upward from the shell 1 in alinement with. the opening 6 of saidchamber. This tubular extens1on 7 is internally threaded to receive a threaded enlargement 8 carried by thel shank or stem 9 of the main valve 10.

The valve shank or stem 9 is provided'at its outer end with an operating wheel or handle 11 which may be of any suitable or deslred construction. The extension 7 is closed at its outer end by a cap 12 having a central aperture 13 .through which the stem 9 of the valve 10 passes and` is adapted This extension 7 also has an auxiliary closure formed within the cap 13 and shown in thecform of an apertured metal disk 14: which seats 'in the outer end of the extension 7 and has arranged thereover a coperating locking member in the form of a disk 15 preferably made of hard rubber which is carried by the cap 12 and between which and said cap is arranged a packing 16 to insure a watez.

passes through thel cap.

The valve 10 has a seat 17 at its inner end in which -is mounted a hard rubber disk 18 which is designed to seat when closed on an annular shoulder 19 formed on the outer end of an inverted hollow truncated coneshapedV valve seat 20 mounted in theopening 6 of the chamber 4. This tubular or sleeve-like valve seat .20 is externally threaded for engagement with the threaded opening 6 and the inner tapered end thereof is extended into the chamber 4, the outerface of said projecting end being ground to form a seat for an auxiliary valve 21 which is designed to fit over said tapered end and close the outlet from the chamber 4: under conditions to be described. This sleeve 20 may be provided with any suitable means lfor inserting and removing it, an opening such :is-20 being here shown for the insertion. ofan actuating tool.

A stem or rod 22 is carried by the valve the tubular valve seat 20 to a point some distance below the inner end thereof, being .L tight connection where the. valve 'stem 9i' designed to engage the cup-shaped auxiliaryrrr valve 21 and hold said valve normally out of engagementwith' the seat 20, as is shown clearly in Flg. 1.r

Guide ribs 23 are formed on the inner face of the side walls of the chamber 4 between which the auxiliary valve 21 is designed to operate and be guided thereby in Vits opening' and closing movements and held against lateral displacement. These guide ribs 23 which are cast integrally with the casing or shell 1 are provided at their ends with laterally extending stops in the form of-shoulders 24 .for limiting the inward or opening movement of the auxiliary valve 21, as is shown clearly in Fig. 1.

At the entrance of the inlet into the chamber 4 is formed. a transversely extending lip 25, the free end of which terminates at a point spaced from the opposed wall of the inlet 2 from which it projects, thereby reducing the size of the inlet where it enters the chamber and serving to direct the entering fluid downwardly against. the rounded chamber bottom 5 of the chamber 4 and against the lower face of the cup-shaped valve 21 which is positioned substantially in alinement with the lower edge of the defiecting lip 25 so that thefcrce of the water is exerted against said valve and when the main valve is removed, will operate to quickly seat the valve against the tapered end of the valve seat 20. The entering Huid impinges against this rounded chamber bottom and is thereby directed upwardly in a direction sufficiently at right angles to the direction of its entrance whereby the force of the in owing current is directed against' the lower face of the auxiliary valve 21 and exerts its pressure to force said valve to- 'ward its seatso that when the stem or rod 22 is .moved away from said valve it will closely engage the seat formed at the innerl end of the member 20 and securely cut offl the water outlet from the faucet. As shown, this cup-shaped auxiliary valve 21 is in the form of a .ground valve for coperation with the ground seat formed at the inner end of the member 20, and the louter face of said valve is substantially inverted coneshaped so thatthe pressure of the inowing uid will be discharged over the entire area ofthe outer face of said valve and thus hold it firmly seated when the rod 22 is removedfrom its engagement therewith.

From the 'above description, the opera- I tion of this improved valve will be obvious,

it lbeing understood that when the main valve 10 is moved inwardly into closed position as shown in Fig. 1, the disk 18 carried thereby will be'seated on the upstanding annular shoulder k19 formed o n the tubular f valve seat 20, and'that when so engaged, 60-

the rod or stem A22 will engage the cupshaped auxiliary lvalve 21 and hold it 1n open-'inoperative position againstl the stops 24 formed on the guide ribs 23, as is'shown clearly in- Fig'. 1. When itis' desired to open the faucet. for permitting the passage therethrough of the iuidl to be discharged, the valve 10 is opened by turning the valve stem 9 in the proper direction to move said valve outwardly into the position shown in Fig- 2, whereby communication between the inlet 2 and the outlet 3 will be effected throu h the tubular sleeve 20, the rod 22 be .ing o a length sufficient to hold the auxiliary valve open when the main valve is. in this position and thus prevent interference of said auxiliary valve with the discharge of the fluid through the faucet.

When for any reason, it is desired to remove the main valve 10 or to obtain access to its seat for repairing or other purposes, the operatin handle 11 is turned until the threaded en argement 8 -is entirely disengaged from the threaded extension 7, whereby the valve is entirely disconnected from the faucet, and immediately the stem 22 passes out of its engagement with the auxiliary valve 21, the force of the water pressure in the chamber 4 will cause said valve to seat firmly against the inner end ofthe tubular member 420, as shown in Fig. 3, thereby cutting oi the outow ofthe fluid through the faucet. After the valve 10 has been repaired or a new one substituted, it is replaced in the faucet by reversing the op- .'eration above described, whereby the stem 22 will again be engaged with the auxiliary valve-21 to force it away from its seat and prevent it from closing or cuttin off the outflow through the faucet, the out ow then being controlled by the main valve 10.
