This invention relates to an improved waste valve and overflow combination for bathtubs, lavatories, etc., and is particularly concerned with a novel form of operating means by which the waste discharge valve may be readily opened and closed .by means of acomparatively simple and sturdy construction.
The embodiment of our invention set forth in the accompanying drawings and in the description which follows is especially suited for use withplumbing fixtures of the kind which are usually employed in connection with built-in bathtubs, for example, although itjwill be apparent that it may be employed advantageously with lavatories, sinks, washbasins, and the like. With built-in bathtubs, for instance, the overflow and waste pipes are usually positioned within the wall. at one end of the tub and thereafter concealed behind the wall of the tub or fixture proper, making inspection or repair relatively difficult. In realization of this problem, efforts in the past have been directed to constructing the waste valve operating mechanism so that it might fit inside the conventional L-shaped channel or conduit connecting the overflow and waste openings. The general practice has been to extend the waste valve operating mechanism through this L- shaped passage from the overflow outlet to the waste outlet. In order to make the mechanism fit operably into this relatively restricted channel and also be removable for repair, it has necessarily required a relatively complicated structure, expensive to manufacture.
Accordingly, an important object of our invention lies in the provision of an overflow and waste operating mechanism for assembly within the overflow. and waste pipes of the character described in which quick and simple adjustments may be made in the seating position of the waste valve or in making simple repairs to the valve seating surface or waste valve during the course of actual service. 1
Another object lies in the provision of a rigid or semi-rigid, generally L-shaped serpentine or undulated form of lift rod which fits snugly within the overflow pipe guide means or conduit and extends into the horizontal portion of the waste pipe where the plain end thereof may engage a complementary downwardly projecting portion of the waste plug for the purpose of providing an improved guided operating mechanism as herein after explained in greater detail.
Additional objects and advantages will become more readily apparent upon proceeding with the of Fig. 1.
following description in connection withthe accompanyi ng drawings, in which- Fig. 1 is a vertical sectional assembly view of a preferred mechanism embodying our invention. Fig. 2 is an enlarged sectional view taken on the line 2-2 of Fig. 1. I P V Fig. 3 is a Vertical exterior view of a preferred form of combined waste valve support and adjustment means therefor.
Fig. 4 is aisectional view taken on the line 4-;
Fig. 5 is a vertical view taken on the line 5-5 of Fig. 4 showing the detailed form of crank means for actuation of the valve from open to closed position and vice versa.
Like reference characters indicate like parts throughout the various views.
Referring to Fig. 1, the numeral 5 refers generally to the end'of a bathtub of the built-in type, or similar fixture, having the waste or drain opening 2 associated with thelaterally disposed waste pipe 3. At its upper portionof the end wall the tub I is provided with the usual overflow aperture 4 cooperating with the vertically extende ing overflow tube or stand pipe 5. The overflow tube 5 is connected at its upper end in the usual manner to the tub overflow opening t by means of an elbow-fitting 6 having a flange 1 positioning an annular gasket 8 pressed against the outer face of the tub wall.
As more clearly shown in Fig. 4, connected with the elbow-fitting 6 by means of the internally and externally hollow screws 9, the apertured annular plate Ill bears against the inner face of the tub wall. A cover plate II is positioned over the overflow opening 4 of the tub I by means of screws 12 which are threadedly connected to the aforementioned hollow screws 9. The cover plate II serves the two-fold purpose of first, concealing the overflow opening proper, and secondly, providing the actuating mechanism bearing l3. Rotatably mounted within the bearing I3 the stem 14 is positioned having an operating handle I5 attached, as indicated, at one end thereof.
Referring again to Fig. l, the overflow and waste pipes at their intersection are connected to the T-fitting It in the manner indicated, there after discharging into the outlet pipe I1, and thence into the usual trap and sewer (not shown) The waste pipe 3 is threaded into the waste elbow l8 which is held against the underside of the waste opening 2 by means of the seat bushing l9 which is screwed into the vertical opening of the waste elbow I8 from the inside of the tub, with a suitable gasket or packing 20 interposed said waste opening, adjusting means associated with the said valve member whereby the axial position of the said valve member with relation to the said waste opening may be varied within predetermined limits, rod means within said L- shaped conduit connected operably to said valve member and extending substantially to said overflow opening, the rod means being formed to con tact diametrically opposite points of the inside wall of the L-shaped conduit and thereby prevent lateral movement of the said rod means, the said adjusting means comprising interconnected threaded members, one of the said threaded members having operative connection with the said rod and with the said closure member, the second threaded member being threadedly connected to the first threaded member and interposed between the said closure member and the said first threaded member.
