LAVATORY WASTE AND FITTING Filed Jan. 16, 1933 2 Sheets-Sheet 2 ATTORNEY Patented Mar. 3, 1936 UNITED STATES PATENT OFFICE 8 Claims.

My invention relates to improvements in lavatory wastes and fittings therefor.

Waste valve fittings are customarily positioned in a housing formed separately from the lavatory. To prevent corrosion, both the waste valve fitting and the housing are customarily made of brass, polished and nickel or chromium plated to improve the appearance. Brass is a relatively expensive metal, particularly when polished and plated, and it is an object of my invention to reduce the cost of manufacture by greatly lessening the amount of brass which must be used, accomplishing this result by providing such variations of the usual construction of waste fittings as will permit the housing to be cast integral with the lavatory.

Constructions such as previously described also require the formation of several joints which are not only unsightly and potential sources of leakage, but are expensive to produce since their production requires considerable tapping, threading and machining. The necessity of assembling several joints also materially increases the time necessary for installation of the fitting. It is another object of my invention to reduce the number of joints necessary, improving the appearance and materially reducing the cost of manufacture and installation.

Another object of my invention is to provide a construction of valve which may be readily disassembled for cleaning.

A further object of my invention is to provide an improved coupling between the lift rod and the valve actuating mechanism.

I attain these objects by the use of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side sectional elevation of a lavatory showing one form of the improved waste and fitting, Fig. 2 is a sectional view of the connection between the lift rod and the valve actuating member, Fig. 3 is a side sectional view of a modified form of waste and fitting, and Fig. 4 is a sectional view thereof along the lines 55 of Fi 3.

Similer numerals refer to similar parts throughout the several views.

Although the improvement is herein illustrated and described with particular reference to its use in connection with lavatories, it is adaptable to other plumbing fixtures such as sinks, etc., and they are considered equivalents of the term lavatory as used herein.

In the drawings the numeral l indicates a lavatory formed with an integrally cast overflow channel 2 which has communication with the bowl or basin 4 of the lavatory through the overflow aperture 3 positioned near the top of said basin. The overflow channel 2 has communication with the housing 5 forming part of the overflow channel 2, also cast integral with the lavatory and adapted to enclose the waste plug valve as hereinafter described. The lavatory bowl 4 has a waste aperture 6 at the bottom thereof communicating with the housing 5. As will be seen from the illustration the overflow channel is positioned at the rear of the fixture and extends upwardly from the waste aperture to the outlet aperture. An annular valve seat 1 is positioned in the waste aperture 6 and is provided with a tubular tailpiece 8 extending downwardly and through the drain aperture 9 positioned to register with the waste aperture 6. A nut l0 threaded on the tailpiece 8 holds the valve seat and tailpiece in position and compresses the gasket II which seals against leakage. The tailpiece 8 is apertured between the waste aperture 6 and the drain aperture 9 to permit the passage of fluid from the overflow channel and the hereinafter described valve actuating means therethrough. The nut I0 is provided with an internally threaded skirt I2 to which is attached. the drain pipe l3. Thus the attachment of the drain pipe requires but a single joint. The tubular waste plug valve l4 extends into said channel and said tailpiece is slidably mounted in the tailpiece and adapted to seat on the valve seat 1 and is provided with a number of slots or openings I5 which furnish a passageway for the water when the valve is in the raised position shown by the dotted line of Fig. 1.

As aforementioned, the housing 5 is cast integral with the lavatory I. The housing 5 is provided with the inwardly extending shoulder or boss having the externally opening bore 2|, threaded'at l9, formed therein. The shoulder 20 is likewise provided with a bore or aperture 35 of smaller diameter than the bore 2| and opening internally of the housing 5. The bore 2| and bore 35 connect to form a socket for the ball 22 of the actuating member 23 which extends through said bores to engage the valve I4. The bore 35 opens into the channel 2 at a point above the juncture of the drain pipe [3 with the tailpiece 8 at a point approximately in the same lateral plane as the aperture in the valve tailpiece and is preferably positioned in the rear wall of the channel 2. Thus the entire valve operating mechanism is positioned on the fixture itself rather than in a separate housing, making a more compact and sightly installation, decreasing the the actuating member 23 ordinarily extends, for

number of joints, eliminating much expensive polished and plated material and greatly reducing the cost of manufacture. It will be understood that the ball 22 may be semi-spherical instead of spherical as shown, or any other construction which will provide a swivel or pivoted joint may be used. The bore 2| and shoulder 29 may, if desired, be formed separately from the housing and inserted through a suitable aperture therein. An externally threaded nut 24 provided with an inwardly extending shoulder 25 is threaded into the nut l9. A coil spring 25 abuts the shoulder 25 and bears against the ball 22. The packing 21 forms a seat for the ball 22 and prevents escape of water around the ball. The lift rod 28 extends through the lavatory l and is held in position in any suitable manner such as by the guide nut 29.

A connecting link 39 is provided with an aperture 3! through which the actuating member 23 protrudes, thus vertical movement of the link 30 is transmitted to the actuating member 23. The link 30 is also provided with an aperture 32. A shoulder nut 33 is threaded on the lift rod 28 with the shoulder uppermost, the dimensions of the nut being such that the shoulder will overlie the aperture 32 while the main or body portion of the nut will enter this aperture. A similar nut 34 is positioned upon the lift rod 28 with the shoulder lowermost and is turned up to abut the nut 33. This allows the lift rod to be rotated, as often accidentally occurs in practice, without varying the vertical adjustment of the link 33 or causing it to become disengaged from the lift rod, as occurs when the link is threaded directly thereto. The slight space between the nuts 33 and '34 and the aperture 32 provides the coupling with some degree of flexibility without objectionable looseness.

The operation of the valve will be apparent from the foregoing description. Lowering the lift rod 28 acts through the link 30 to depress one extremity of the actuating member 23 and raise the opposite extremity, the actuating member being pivotally mounted at the ball 22, raisingthe valve l4 to the position shown by the dotted line of Fig. 1. Raising the lift rod reverses this action and causes the valve to close. The coil spring 26 holds the ball 22 in engagement with the packing 21 and prevents leakage of water. The

' nut 24 retains the spring 26 and the ball 22 in position and also provides a means of adjusting the pressure created by the spring 26 on the ball 22.

The entire construction may be readily disassembled by removing the nut 24 when the coil spring 26 and the entire actuating member 23 may be withdrawn. The valve l4 may then be removed and cleaned. A suitable tool may be inserted through the aperture 35, through which the purpose of cleaning the inside of the housing 5. This is an important feature, since valves frequently become clogged with hair, sediment, etc., and as ordinarily constructed there is no practical method of cleaning out the valve when this occurs.

It will be seen from the foregoing that I have constructed a valve which is simple in operation and economical to manufacture, since the valve housing is formed integral with the lavatory, as is the seat or socket for the valve actuating mechanism. The amount of expensive brass which must be used is reduced to a minimum, and only one joint is required to attach the drain pipe to the tailpiece of the valve, reducing the amount of tapping and machining required.

A modified form of my invention is shown in Figs. 4 and 5. In this form the housing 5 is apertured at 36 and 31 to permit the positioning of the sleeve bolt 38 transversely of the housing. The bolt 38 is secured by the nut 39, gaskets 40 and 4| being provided to prevent leakage. The bolt 38 is provided with the bore 42, adapted to receive the spindle 43. The finger 44 is splined or otherwise non-rotatably attached to the spindle 43 and passes through the tailpiece 8, it being understood that the tailpiece is apertured for this purpose and for the purpose of allowing Water to pass from the housing 5 into the bore thereof.

The finger 44 has an enlarged or bulbous end portion 45 adapted to fit in a slot or aperture in the waste plug valve I4 whereby vertical movement of the finger causes a corresponding vertical movement of the waste plug valve l4 and raises it from or seats it on the valve seat 1. A crank arm 46 is splined or otherwise non-rotatably attached to the spindle 43. The opposite extremity of the crank arm 46 terminatesin a yoke 41. A clamp 48 has a trunnion 49 extending through an aperture in the yoke 41. A set screw 50 having a conical point extends through an aperture in the opposite side of the yoke 41 and is threaded in and extends through the clamp 48. The set screw 58 acts as a trunnion so that the clamp 48 is pivotally mounted in the yoke 41 and also acts as a clamping means for the spring 5|. The spring 5| is attached, by means of suitable clamping means 52, to the lift rod 28 which extends through the lavatory I. The lift rod 28 may extend through the faucet 53 as illustrated.

From the above description it will be evident that manipulation of the 'lift rod 28 will act through the spring 5|, crank arm 46, spindle 43 and finger 44 to raise and lower the waste plug valve M. The spring 5| creates a tension and sufiicient friction to prevent the waste plug valve from closing by the force of gravity, and is advantageous with this type of construction. However, the form of coupling illustrated in Figs. 1 and 3 may be used if desired.

The construction above described possesses many of the advantages of the preferred form of my invention, shown in Fig. 1, such as reduction of the amount of expensive metal required, reduction of the number of joints, etc. All of the operating mechanism, with the exception of the waste plug valve 1 and the finger 44, is located outside of the water passageways, thus there are no obstructions in the main water passageways likely to cause clogging and the area subject to fouling by waste water is materially reduced.
