(Cl. 4-l99) 1 Claim.

My present invention relates to waste and overflow outlets for baths, sinks, basins and the like, and more particularly to an improved combined waste and overflow outlet fitting.

My present invention, while designed primarily for use in connection with baths, sinks or other commercial personal convenience receptacles, where it is necessary or desirable to have not only a waste outlet but a Waste overflow outlet, is adapted for use in connection with any receptacle for holding fluids and where an eflicient and convenient combined waste and overflow outlet fixture is desirable or necessary.

In carrying out my present invention, I preferably make the combined waste and overflow outlet; fitting as an entity separate from the receptacle with which it is to be associated, and arrange the overflow outlet fitting either as a'unitar'y structure or as a plurality of elements making up a structure having the individual elements 5 adjustable relatively to each other, and wherein the operating mechanism for the waste outlet valve may be inserted within and conveniently housed in the waste and overflow outlet.

The object of my invention therefore is an improved waste and overflow outlet fitting for a container for water or other fluid.

A feature of my invention resides in the inclusion within the waste and overflow outlet fitting of a waste outlet valve of the shear gate type.

A further feature of my invention is an improved waste and overflow outlet fitting adaptable for bottom or lateral discharge therefrom.

Various other features of the invention will appear as the description of the invention progresses.

In the accompanying drawing:

Fig. 1 is a vertical sectional elevation of the waste and overflow outlet and of a container for fluids to which my present invention has been applied, the structure embodying the invention being shown in sectional elevation;

Fig. 2 is a front elevation of the structure shown in Fig. 1, and

Fig. 3 is a mere elevation partly broken away in section of the shaft and overflow outlet fitting shown in section in Fig. 1.

I have illustrated in the drawing two embodiments of my invention, each illustrating the use of a shear gate valve in connection with the waste outlet opening of a fluid container. One embodiment also illustrates a lateral discharge outlet from the waste and overflow outlet fitting, and the other embodiment a bottom discharge. Further, in one embodiment waste and overflow outlet fitting is built up of a plurality of' elements, all adjustably associated with each other, and in the other embodiment the waste and overflow outlet fitting is a relatively massive hollow casting, and this also contains the shear gate type of waste outlet valve.

Referring to the drawing, and particularly to Figs, 1, 2 and 3, l0 designates the waste and overflow outlet end of a container, such as a bath, sink or the like for water or other fluids and in which there is arranged at the bottom thereof a Waste outlet opening II and adjacent to the top thereof a waste outlet opening [2. There is associated with the waste outlet opening I I a waste outlet valve to be presently described, and which when closed, will permit fluid, such as water, to be kept within the container Ill and until the height of such fluid rises above the lower edge of the overflow outlet opening I 2. This overflow outlet opening ordinarily is always open and therefore it acts as a spillway to permit excess of fluid to flow out of the container In.

I have associated my present invention with the above described waste and overflow outlets l I and I2 respectively. In the drawing, I3 designates an overflow outlet fitting having an internally threaded orifice l4 therein and which is adapted to receive the externally threaded end I 5 of a combined bearing and strainer member IS. A washer ll, of preferably resilient material such as rubber, is employed as shown in Figure 1 to assist in maintaining a fluid-tight joint between of the invention the I the member 5 and the internally threaded opening of the fitting I3. The lower end l8 of the fitting I3 is substantially cylindrical and is counterbored to receive as a snug sliding fit the upper end of a tubular member I 9 of any suitable length and which tubular member extends downwardly to a point adjacent to but above the waste outlet H.

Associated with the Waste outlet II is a fitting 20 substantially tubular in form and provided with a passage 2| extending therethrough and when the fitting 20 is in position relative to the waste outlet II the passage 2| registers with the waste outlet ll. Formed integral with the fitting 20 and within the passage 2| is a boss 22'drilled and tapped to receive the threaded end of a headed bolt 23. One end of the fitting 20 is contoured to the shape and form of the lowercorner of the container ID, as shown in Fig. 1, and interposed between the contoured end of the fite ting 29 and the container I!) is a gasket 24 of any suitable material.

As shown, the material of the container l surrounding the waste outlet II is contoured to provide a recess in which is seated a strainer 25 in such a manner that the surface of the strainer lies substantially flush with the inner surface of the container ID, This strainer 25 is provided with a perforation through which extends the body portion of the threaded bolt 23, and it will be apparent that as the bolt 23 is screwed into the boss 22, the fitting 20 will be brought into close and fluid-tight association with respect to the waste outlet I l of the container I6.

Associated with the free end of the fitting 20, and with the lower end of the tubular member I9, is a fitting 26 which may be of any suitable material and preferably is of metal. As shown in Figure 1 the fitting 26 is hollow and its upper end is internally recessed to receive the lower end of the tubular member [9, and the exterior of the upper end is threaded to receive the internal threads of a packing nut 21 On the upper end of the fitting 26 and within the packing nut 21 is resilient packing 28 which, when the packing nut 21 is screwed onto the fitting 26, assists in maintaining a fluid-tight joint between the fitting 26 and tubular member IS.

The fitting 26 in alignment with the fitting 20 is provided with a passage through which the cylindrical end of the fitting 20 extends terminat ing at a point within the fitting 26. This end of the fitting 26 is externally threaded to receive the threads of a packing nut 29 which in association with the packing 30 serves to maintain a fluid-tight joint between the fitting 26 and fitting 29. The fitting 26 is provided with a threaded outlet 3l for connection to any desired waste line.

On the interior of the fitting 26 and on each side of the cylindrical end of the fitting 20 is formed a guideway 32, These guideways are in alignment with each other and form a track on which a shear gate valve 33 may slide, the downward movement of the shear gate valve being limited by the open end of the passage 2| in the fitting 20. The shear gate valve 33 has the face 34 thereof thus coacting with the end of the passage 2| which acts as a valve seat (see Figure 1).

On the shear gate valve 33 is a stud or shaft 35 on which is pivotally mounted the lower end of a connecting rod 36. The upper end of the connecting rod 36 is pivotally mounted on a shaft 31 which is an integral part of a shaft 38.

The shaft 31 is parallel to such shaft 38 and is offset therefrom. The shaft 38 is rotatably mounted in a bearing 39 formed integral with the combined strainer and bearing member l6. The shaft 38 has secured at its end an operating handle 40 and by means of which the shaft 38 may be rotated in the bearing 39 to rotate the shaft 31 about the same as a center and thus cause an upward or downward movement of the shear gate valve 33.

The fittings I3 and 20, when secured to the container ill in the manner above described, determine the ultimate position of the fittings 26 and I9, but it is quite apparent that a considerable degree of flexibility as regards a fitting or adjustment is permitted by the manner of associating the various fittings together. Also should it be desired, it is quite possible to remove the fitting l3, or the fitting 20, and some of the associated fittings without disturbing the seating or adjustment of the fitting l3 with respect to the container l0.

Whereas I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention. I

I claim:

An improved waste and overflow outlet for receptacles for liquid and the like and in which there is provided a recess surrounding the overflow outlet, comprising in combination, a hollow waste and overflow outlet fitting, means for attaching one end of said outlet fitting to the overflow outlet of the receptacle, a bearing centrally located in the attaching means, a combined bottom outlet and attaching means for securing said outlet fitting to the bottom outlet of the receptacle, said latter attaching fitting including a shear gate'valve seat located interiorly of the outlet fitting and also including a strainer contoured to fit within the recess in the receptacle and with the outer surface of such strainer lying flush with the interior surface of the receptacle, means passing through the strainer for clamping the outlet fitting onto the receptacle, a shear gate valve associated with the valve seat, a shaft provided with a crank arm rotatably mounted in the aforesaid bearing, connecting means extending between the crank arm and the said shear gate valve, and a lever attached to the outer end of the shaft, and within the confines of the receptacle, for operating said valve.
