TUB SPOUT DIVERTER Filed Feb. 20, 1967 2 Sheets-Sheet l Oct. 21, 1969 P. A. MONGERSON TUB SPOUT DIVERTER 2 Sheets-Sheet 2 Filed Feb. 20, 1967 llnited States Patent Jersey Filed Feb. 20, 1967, Ser. No. 617,137 Int. Cl. F16k 31/44, 51/00 US. Cl. 137-467 10 Claims ABSTRACT OF THE DISCLOSURE This invention relates to a tub spout diverter of the type which will stay in the closed or shower position once it has been moved to that position, but which will drop down to the tub position when the water is turned oil. Basically, the invention includes a spout housing, a diverter mounting means which is removably attached to the housing, and a reciprocal diverter which is held in place by the diverter mounting means. The reciprocal diverter may also include a stream forming member. The diverter member includes an annular pressure surface which is eflective to hold the diverter in the shower position by virtue of water pressure upon it.

This invention relates to a tub spout diverter and particularly to such a diverter which can remain in the shower position as long as the water pressure is on, but which will automatically drop to the tub position when the water is turned off.

A primary purpose of the invention is a tub spout diverter of the type described which includes a removable diverter mounting means within the spout housing or shell.

Another purpose is a tub spout diverter of the type described including a stream forming member within the diverter.

Another purpose is a tub spout diverter of the type described including a reciprocal diverter member having an annular pressure surface for use in holding the diverter in a closed or shower position.

Another purpose is a simply constructed, reliably operable, tub spout diverter.

Other purposes will appear in the ensuing specification, drawings and claims.

The invention is illustrated diagrammatically in the following drawings wherein:

FIGURE 1 is a side elevation of a spout housing, with the operating handle of the diverter member-extending outside of the housing,

FIGURE 2 is an enlarged vertical section through the structure of FIGURE 1, illustrating the diverter in the closed position,

FIGURE 3 is an enlarged vertical section of the structure of FIGURE 1, illustrating the diverter in the open position,

FIGURE 4 is a bottom view of the diverter and housing, and

FIGURE 5 is an end view illustrating the diverter mounting means and its connection to the spout housing.

The spout may have a somewhat conventionally shaped housing having a discharge opening 12 with a Water conduit or water pipe 14 extending into the housing as is customary for mounting plumbing fixtures of this type. The housing 10 may be formed of a variety of materials, for example brass, zinc, or plated plastic.

Within the housing 10 is a diverter mounting means indicated generally at 16 which may be a casting, for example brass. The mounting means 16 includes a water passage section 18, internally threaded as at 20, for mounting the water pipe or water conduit 14. There is Patented Oct. 21, 1969 a cylindrical diverter mounting section 22, which is a part of the diverter mounting means 16 and which is connected to the passage section 20 by means of an opening 24. The opening 24 may be semicircular in cross section, as shown in FIGURE 5. The Opening 24 will place the interior of the diverter mounting section 22 in communication with the water pipe 14. The mounting member 16 may have an outwardly extending flange 26 which can be positioned adjacent a pair of downwardly extending projections 28 on the interior of the housing so that mounting screws or the like 30 may be used to fasten the diverter mounting member to the housing 10. The projections 28 may extend inwardly from the top, sides or bottom of the housing 10. The housing 10 may have internal inwardly extending guide members 32 which extend toward and are in contact with the outer cylindrical surface of the mounting section 22 for properly positioning the diverter mounting means within the housing.

As mentioned above, the diverter mounting section 22 is generally cylindrical in form and may have an upper opening 34, which is in alignment with an opening 36 in the housing 10. A stem 38 passes through the

aligned openings

34 and 36 and may have a knob or the like 40 at its outside end. The stem passes downwardly through a sleeve 42, which may be formed of brass or the like, and which is fixed in the opening 34. In eflFect, the sleeve 42 provides a guide for the stem 38.

Within the cylindrical section 22 is a cylindrical diverter member 44, which has a flange or flare 46 functioning as an annular pressure surface at its open upper end. The lower end of the diverter member 44 may have an annular groove 48 which mounts a stream forming member 50. The lower end of the stem 38 may be attached to the stream forming member 50, by means of an enlarged nose or the like 52. Surrounding the diverter member 44 is an annular seal 54 which is held in position by a snap ring or the like 56, positioned in a groove 58. The seal 54 is effective to seal the outer annular surface of the diverter member 44.

As illustrated particularly in FIGURE 4, the stream forming member may be somewhat sinuous in cross section providing a plurality of curved sections or curved openings for directing water to the tub below the spout. Water also flows through the intermediate areas 62 and 64 which are formed by the sinuous stream forming member 50.

In operation, assuming the diverter has been moved to the shower position of FIGURE 2, Water flowing through the conduit 14 and the water passage 24 will enter the annular chamber formed by the outer surface of diverter member 44 and the inside surface of the diverter mounting section 22. Water pressure Within this chamber will provide an upwardly directed force on the flange 46. Inasmuch as there is no corresponding surface below the water passage 24, or stated another way, inasmuch as the surface with the greater diameter is above the passage 24, the diverter member 44 will be held in the up position by means of the upwardly directed water pressure upon the flange 46. The diverter member will stay in this closed or shower position as long as the water pressure remains on. The lower side of the diverter member is sealed by the annular seal 54 so that there is no leakage at this point.

As soon as water pressure is turned off, there is nothing to hold the diverter in the shower position of FIG- URE 2 and it will automatically drop to the tub position of FIGURE 1. Note that in the tub position the lower surface of the knob 40 abuts or seats against the upper surface of the housing 10, thus limiting downward travel of the diverter. The flange 46 does not rest upon the seal 54, but is spaced above it because of the abutting surfaces of the knob and the housing .10. The outside annular surface of the diverter is sealed so that there will be no water leakage at this point and all water will flow downwardly through the diverter member.

The stream forming member is important and it has been found to provide an excellent flow pattern, with minimum splash into the tub. The sinuous pattern or cross sectional area of the stream forming member provides suflicient dispersion of the water to minimize splash, yet there is a suflicient stream such that the water coming out of the tube spout does not appear to be in the form of a spray.

Of importance is the means of attaching the diverter mounting means. When the spout housing is to be used without a diverter, a different bracket for attachment to pipe 14 may be provided. The snap ring 56 provides for quick disassembly of the diverter for replacement of any worn parts. Note particularly that there is only a. single seal, with the remaining internal members all being formed of brass or some other suitable material resistant to water. The housing may be metal or a plastic clad metal. It may be cast, molded or stamped. Note also that the housing does not have water in contact with it, thus permitting the housing to be entirely of plastic, if so desired.

The spout in its cast form may be used with or without a diverter. The diverter itself may be removed by first taking snap ring 56 out of its groove. In the alternative, a dilferent housing may be used to attach pipe 14. When used Without a diverter, the opening 36 in the housing may provide a degree of aeration of the water stream.

The invention should not be limited to the stem 38 and knob 40 as the operating means for the diverter. For example, movement of the diverter may be controlled by a lever which extends through a forward slot in the housing and is attached to the diverter. The lever may be hinged at its rear end so that upward movement of the lever will bring the diverter to a shower position. In like manner, the diverter may be raised by pushing it up from the bottom.

Whereas the preferred form of the invention has been shown and described herein, it should be realized that there are many modifications, substitutions and alterations thereto within the scope of the following claims.
