FAU'CET I'Filed May 2l', 1957 Patented May 23, 1939 UNITED STATES PATENT OFFICE 4 Claims.

larly to the types and sizes used in homes and the like for controlling the flow rand dispensing of water for domestic uses. An object of the invention is to provide a faucet of the character described which will afford an improved fluid tight closure of the faucet valve and at the same time greatly reduce the amount of wear and strain on the valve in comparison with faucets of a similar type heretofore available. n

Another object of the invention is to provide a faucet of the character described which in its partially and fully opened position will be subu stantially quiet and silent in operation.

Another object of the invention is to provide a faucet of the character above which will be constructed of a few simple and ruggedly formed parts which will insure long and positive operation of the faucet and enable a manufacturing cost comparable with faucets heretofore in use.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the show ing made by the said drawing and description may be adopted within the scope of the invention as set forth in the claims.

rReferring to said drawing: y

Figure lis a vertical sectional view of a faucet constructed in accordance with the present lnvention, and showing the faucet valve in closed position.

Figure 2 is a view similar to Figure 1, but showing the faucet valve in open position.

Figure 3 is a transverse sectional view of the faucet and is taken substantially upon the plane of line 3-3 of Figure 1.

Figure 4 is a vertical sectional view of a modified form lof the faucet.

The faucet of the present invention, and as illustrated by the preferred embodiment in the accompanying drawing, comprises a main vbody 6 which is formed at the interior thereof with a ball shaped valve chamber 1 which opens to the top side 8 of the body by way of a cylindrical bore 9. Formed in extensions II and I2 of the body are inlets and discharge passes I3 and I4 which open to the chamber 1 at the bottom I5 and an intermediate side I1 thereof respectively. The passages I3 and I4 are normally sealed from each other by the interposition of The invention relates to faucets and particu-- a valve casing I8 which is inserted into the chamber 1 through the bore 9 at the upper end 8 of the body and extend from this end to the bottom I6 of the chamber. The casing is sealed to the walls of the lbody at the lower end I9 of the 5 casing by means of a gasket 2| which is compressed between an annular shoulder 22 formed at the lower end I9 of the casing and a seat 23 formed around the lower end I6 of the chamber.

If desired, the gasket 2I may be dispensed with l0 and the shoulder 22 caused to engage directly in the seat 23 where a relatively good metal to metal contact is provided. The upper end 24 of the valve casing is also sealed to the side walls of the valve chamber by preferably using a relatively snug t between the periphery of the casing and the bore 9 and by providing over the top of the casing and the top 8 of the body a washer 26 which is held in place by a threaded cap 21 surrounding and secured to the top of the valve body. Due to the substantially complete lack of pressure at the top of the valve chamber, by reason of the full flow afforded the liquid by the discharge passage I4, the requirement for se'aling the valve casing in the top of the valve chamber presents no substantial difficulty.

The liquid or fluid flow through the faucet and more particularly through the valve chamber 1 from the inlet passage I3 to the discharge passage I4, is provided by way of a passage 21 formed 30 in the lower end I9 of the valve casing and opening to the lower end face 28 of the casing and being communicated with the interior of the chamber for flow into the discharge passage I4 by way of a plurality of circumferentially spaced ports 29 formed around the periphery of the valve casing adjacent the lower end thereof. The flow of fluid through the passage 21 is controlled by a valve 3| carried by the valve casing and disposed below the bottom face 28 thereof in the in- 40 let passage I3 and being movable into and from a position in engagement with the end face 28 for shutting off the communication of the inlet passage I3 with the valve casing passage 21. The valve itself is composed of a supporting receptacle 32 for a washer or packing member 33 which is engaged with the lower end face 23 of the casing and to insure a proper seating of the washer 33 against the face 28, the latter is preferably reduced in thickness somewhat, as here shown, so as to increase the unit area pressure of the engaged sealingv surfaces of the end face and the washer. The valve piece 32 in the present embodiment is connected as by means of a screw 35 to a valve stem 34 which extends longitudinally 55 through the valve casing by way of a central bore 36 into an enlarged bore or chamber 31 provided in the upper end of the valve casing. Secured to the valve stem in this latter chamber 31 is a spring 38 which is compressed between a washer 39 at the bottom 40 of the chamber and a cap washer 4| at the top of the stem for drawing the stem lengthwise through the valve casing and the valve 3| against the lower end face 28 of the casing in closed position. Preferably the portions of the washer v39 and the bottom wall 40 opposed to the stem are cut away to define a chamber for the stem 34 for causing an opening of the Valve is here effected by an operating member 42 which l is extended through an opening 43 in the cap 21 and is threaded into the chamber 31 of the valve casing, the lower end of the member being provided with a socket 44 for engagement overthe upper end of the stem 34 and the spring 38 and being adapted to engage with the cap washer 4| on the stem for depressing the latter and opening the valve upon screwing of the member into the chamber 31. The lower portion of the member 42, which isthreaded into the socket 31, is preferablyformed asa slight enlargement 46 over the remainder of the member extending from the faucet and preferably the size of this enlarged portion 46 is such that with the member 42 unscrewed to a position slightly beyond a position disengaging the stem 34, and as illustrated inv Figure l, the upper shoulder 41 of the enlargement 46 will be substantially flush with the top of the valve casing and of the faucet body. In

35i this manner the washer 2B, clamped over the top ofk the-faucet body and the valve casing, may also overlie the portion 46 ofthe actuating stem and thereby limit the outward movement of the operating member relative to the valve casing and 4,5 ample displacement of the valve stem 34 'and opening of the valve 3| when the operating member has been screwed to its innermost position in the valve casing chamber 31, as shown in Figure 2. Any suitable hand engagable member 49,

my; such as the hand wheel here shown, may be attached to the upper end of the operating stem 42 for rotating the same. Such a means is well known in the art and may take the form of ay wheel or lever, or the like.

55; An important feature of the present construction is the use vof the plurality of circumferentially spaced ports 29 for communicating the interior passage 21 of the valve casing withfthe valve chamber 1 and the discharge passage I4. This arrangement acts to expand rather than contract the passage area afforded the liquid after passing through the valve seat and it otherwise serves in conjunction with the general arrangement illustrated to very substantially reduce the noise of the liquid flow at partial and full open positions of the valve.

A modified form of the faucet has been illustrated in Figure 4 wherein the body 6 of the faucet-has been designed in a manner not requiring the use of the separate valve casing |8 of the first embodiment. In this form of the invention, the inlet passage I3' and the discharge passage |4 are formed in the body in substantially longitudinal alignment and separated by the wall 5|'which is formed, in part, with a horizontal portion having an opening 52 therein for the passage of liquid from the inlet to the discharge passage. The sides 53 of the wall 5| surrounding the opening 52 are extended downwardly from the remainder of the wall so as to define at their lower end face 54 a seat for the valve 3|. The latter is secured as by means of a screw 51 to the lower end of a valve stem 34' which is reciprocally carried in a bore 58 provided in a top wall portion 59 on the body and extends into a chamber 31 in the top of the portion 59 and resembling the equivalent chamber 31 in the top of the valve casing I8 of the rst embodiment. The upper end of the valve stem is supported in the chamber 31 by a cap washer 4| spring 38' and packing means 50' as inthe rst embodiment. Similarly, the actuation of the stem by a manually operated member 42 is effected in the manner described in connection with the first embodiment.

Preferably the lower wall portion 62 of the faucet L is provided with an opening 83 in registration with the opening 52 and the valve 55 for enabling an assembly of ther valve structure and a renewal of the Valve, and as here shown, is normally closed by a threaded plug 64.

A particularly important feature of the present invention and as illustrated in both of the above embodiments, is that the valve 3| is moved from open to closed position by means of the fluid pressure assisted by the spring 38 or 38, both of which are completely out of the control of the operator, and that when the valve is moved to closed position, the manually

operating stem

42 or 42 is disconnected from the valve stem and the valve is held in closed position entirely by the fluid pressure and the spring 38 or 38 and no further manual turning of the manually operated member is effective to apply any further pressure or wedging or compression of the valve against the valve seat. Also in the present faucet there is absolutely no forced turning of the valve against the valve seat, such as is present in faucets now in common use and which is so destructive to the relatively soft compressible valve washers used, since in the first place the top` of the valve stem 34 is journalled in the top of the socket 44 of the actuating member and can freely rotate relative thereto and furthermore the manually controlled member is disconnected from the valve when the latter is moved to its seat. Thus, the initial engagement of the operating member with the valve stem causes a longitudinal displacement of the stem together with any turning force that might be present and as a result the pressure of the valve washer 33 against the end face 28 is immediately relieved and these opposed surfaces spaced before any appreciable turning force exists. Also, upon the return movement of the valve to its seat, any turning force between the valve stem and the operating member immediately disappears upon the seating of the valve due to the disengagement of the operating member and the valve stem at this point. This complete elimination of any twisting or turning action tending to wedge the valve washer into its seat under the usually severe manually applied pressure, multiplies the useful life of the valve washer many times over that heretofore obtained and substantially improves the ability of the Valve to properly engage the valve seat. Furthermore the elimination of the compression of the valve against its seat and providing a free unrestricted movement of the valve to and away from the seat, makes the faucet vastly easier to operate than faucets heretofore.
