Application April19, 1951, Serial No. 221,920

1 Y 1 This invention relates to plumbing fittings, and more particularly to a water supply fitting for a bath tub with valve means for diverting the water flow from such fitting to a shower fixture or attachment.

In such fittings as heretofore constructed, the water supply spout for the tub is provided with a device which may be manually operated to divert the water fiow to a pipe leading to the shower attachment, and when the diverter is not in operation and the usual hot or cold water valves, or 'both, are open, the water passes freely through the tub spout and no water rises through the shower pipe, but after the said diverter is manually operated, the flow of water through the spout is interrupted and the water is'caused to pass through said pipe to the shower attachment and the water pressure is adapted to hold the diverter in this position after the initial manual operation and as long as the supply pressure is maintained.

This arrangement has the disadvantage that the water cannot be conveniently diverted to the shower attachment until after a considerable amount of water has passed through the spout into the tub and an appreciable amount of water escapes through the spout to the tube even while the deflector is in operation, and moreover the closing of the usual valves automatically relieves the water pressure on the diverter device which must therefore be manually operated each time it is desired to deliver water to the shower attachment. These known devices have the further disadvantage that they are liable to cause objectionable nois and wastage of water.

One object of the present invention is to provide improved diverter means capableof being other object is to provide a rotary diverter device that may effectively prevent any passage of water through the tub spout while the shower is Y in operation. Still another object is to provide a device which does not rely upon the water pressure to retain it in position for the supply of water to the shower, and which remains tightly in'position'even'after appreciable wear of the contacting surfaces.

With these and other objects in view, the invention consists in the novel construction and arrangements of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various minor changes in the form and construction may be made without departing from the spirit of the invention or sacrificing any of the advantages thereof.

5 Claims. (01. 1379-5516) Y In the drawing Fig. 1 is a longitudinal section of a water spout with the diverter accordlngto the invention embodied therein, Fig. 2 is aplan view of the spout, showing the extemalpperating means for thediverter, and Fig. 3 is acrosssection on the line 33, Fig. 1.

Referring to the drawings, the spout I0. is internally screw threaded at its water inlet end H to receive an external screw thread on an enlarged end part l2 formed on an internal bushmg 13 that fits into an enlarged bore portion of the bore 20 of the spout, and the extremity of the bushing 13 at the inlet of the spout is internally screw threaded at l4 for the reception of the external screw thread on the end of the usual pipe supplying the hot and cold water to the spout.

The bushing I3 is formed with a'downwardly tapered bore or socket for the reception of a similarly tapered plug l-5 whose lower end is slightly spaced from the lower part of the said bore or socket, and acompression spring 2'] is interposed between the upper part of the plug I5 and the surface of the 'said enlarged portion I 9. The plug 15 has a passage l6 extending therethrough' and may be turned so that the said passage is brought into alignment with ports l1, IS in the bushing so as to provide free passage of water from the inlet pipe to the outlet end ID of the spout. Above the plug IS the spout is bored for the reception of a stem 22 and the upper end of this stem has a. squared end 23 for the reception of an operating knob 24 which is secured on the stem by a Screw 25. The knob 24 is provided with a pointer 26 bearing the V legend Shower" and adapted to register withfan indicator or arrowhead 21 molded or formed on the upper part of the spout. Depending from the under side of the knob 24 is a projection 28 adapted to engagewith one or other of two upwardly

projecting stops

29, 30 formed on the spout, and the pointer 26, when in the position shown in full lines at Fig. 2, is in the "Shower position and the plug It prevents the passage of water from the port [8 to the port I! and, when the pointer 25 is inthe position shown in dotand-dash lines at Fig. -2, the passage I6 is in alignment with the ports I! and I8 and water passes freely to the outlet ID of the spout and no water is then supplied to the shower.

In operation the device may be set in readiness Y for the supply of water either to the tub or to the shower attachment and may remain in such set position indefinitely.

If so desired the plug 15 and stem 22 may be horizontally disposed in the spout instead of vertically as shown on the drawings and the pointer 26 may be suitably modified.

Although the drawings and the above specifications disclose the best mode in which I have contemplated embodying my invention, I desire to be in no way limited to the details of such enclosure, for-in the further practical application of my inventionmany changes in form and construction may be made as circumstances require or experience suggests without departing from the spirit of the invention within the scope of the appended claims.

What I claim is:

1. A fitting for the supply of water from a supply pipe to a bathtub and to a shower fitting or attachment, comprising a water spout casing, an inner bushing fitted in the inlet end of the casing, a screw threaded socket in said bushing for the reception of the water supply pipe, aligned ports in the bushing, atapered plug mounted in said bushing between said ports, a passage in said plug capable of alignment with said ports,

a stem extending through the wall of the spout casing and attached to said plug and preventing relative movement of the said casing and bushing, an operating device attached to the outer end of said stem, means for indicating when said stem and plug are in position to prevent the passage of waterthrough the spout, means for limiting 'the rotary movement of said plug and spring means between the end of the plug and the spout casing'to hold the, plug tightly in position.

2. A plumbing fitting for the supply of water from a supply pipe, comprising a water spout casing, a bore in the casing for the discharge of Water from the spout, an enlarged bore in the inlet portionof the casing, a bushing fitted closely within said enlarged bore, a screw-threaded socket in-the end of said bushing for engaging the watersupply pipe and for supporting the casing upon said pipe, ports formed in the bushing in alignment with each other and with the first-mentioned bore, a rotary tapered plug valve mounted between said ports with its axis at right angles to the axis of said bushing, a water passage in said plug capable of alignment with said ports, and a stem attached to said plug and extending through the wall of said casing.

3. A plumbing fitting for the supply of water f-rom a supply pipe, comprising a casing for a water spout, a bore in said casing for the delivery of water from the spout, an enlarged bore in the within's'aid enlarged bore, a collar on one end of said bushing for screw-threaded engagement with the water inlet end of said spout, a screwinlet portion of the casing, a bushing fitted tightly through the wall of said casing and serving to prevent relative movement of said bushing with respect to said casing, an operating device attached to the outer end of said stem, and means for indicating when said stem and plug are in position to prevent the passage of water through the spout.
