FLUSH VALVE COMPANY, OF MILWAUKEE, WISCONSIN, A. CORPORATION OF WIS- CONSIN COMBINATION FIXTURE Application mea January a5, 192s. serial No. 83,445.

The fixture illustrated in Figures 1) to 4 This invention relates to combination fix- ,tures and more particularly to combined tub and shower xtures.

It contemplates more especially'the pro- 5 vision of a unitary control for selectively admitting a proportionedmixture of hot and cold yvater to either the tub or shower, the control being preferably so constructed and arranged as to regulate the amount of water delivered to either the tub or shower.

One object of the present invention is toimprove the construction and operation of combination ixtures of the character inentioned. v f Another object is the provision of an improved valve mechanism for directing and regulating the flow of water to any of a plu -rality of parts of a combined xture.

A further object is to provide means including a shower attachment, which can be readily combined with a tub already installed, and through which vWater may be delivered to either the shower or tub selectively. Other objects and advantages will appear from the following description of an illustrative embodiment of the present invention.

In the drawings: v Figure 1 is a view of a combined tub and shower xture constructed in accordance with' the present invention.

-ting 17,

. ing

comprises the usual hot and cold water supply pipes 10 and 11, connected to the opposite ends of a cross pipe 12, through the usual regulating valves 13 and 14. The pipe 12 constitutes a mixing chamber for receiving hot and cold waterin proportions determined by the setting of the valves 13 and 14.

4Pipes

10, 11 and 12 are shown disposed within the wall 15 with the valve handles projecting from the wall. A pipe 16, in open communi.-

cation with pipe 12 through the usual T-fit faucet 18 in accordance 'with standard practice.

The faucet 18 is ofnovel construction. jIt is provided with a longitudinal bore 19 havldiametral ports 20 and 21 leading therefrom. The upper port 20 communicates with a pipe 22 screwed into the faucet and constituting a support for a shower head 23. The lower port 21 communicates with a passage 24 leading lengthwise of the faucet to the discharge end 25 thereof through which Water is delivered to the tub 26. The faucet leads through the wall to a bath tub l is supported by and fed from.- the pipe 16 vthrough an approprlate union 27. I

A valve 28 controls communication between the pipe 16 and the ports 20 and 21.v The valve shown is providedwith a hollow cylin- Fig. 2 is a sectlonal view taken substanf--drical head 29 rotatable within the bore 19,

and open to the pipe 16. A substantially'rectangular opening or port 30 through the wall of the hollow valve head cooperates with the ports 20 and 21 to control the admission of vwater from pipe 16 to pipe 22 orto passage 24, selectively. The arrangement is such that with the valve in the'cposition shown in Figure 2, port 20 is closed by the wall of the valve and port 21- is open to pipe 16 through port to the tub only.

30 and water is vsupplied one hundred By rotating the valve through7 and eighty degrees, port 30 is made to registerv with -port 20 and port 21 is' closed, so that water from pipe flows to the shower head'I only. y rotating the valve slightly from either of the extreme positions ust described the rate of flow through ports 21 and 30 may be regulated vwhile the other port remains closed, or the rate of flow through ports 20 and may be regulated while the other port 21 remains closed. It is thus possible to regulate the rate of flow to either the tub or shower while the flow to the other is shut off. In an intermediate position of the valve, both ports 20 and 21 are substantially closed.

It will be noted that when both valves 13 and 14 are open, the hot and cold water supply pipes 10A and 11 are in communication through the cross-pipe 12, and, unless the water in pipe 12 were free to escape, the hot 'water from pipe 10 would tend to pass through pipe 12 and back up into the cold water pipe 11. To avoid this condition provision is preferably made for by-passing a small amount of water from the pipe 12 to eitherthe shower or tub in the intermediate position of the valve 28. This is accomplished in the faucet shown by making the port 30 wide enough so that it is impossible to completely close both ports 20 and 21 at the same time when the valve is in the intermediate position. To prevent this leakage of water through the shower or tub the operator will find it necessary to shut off both valves 13 and 14, and in so doing will avoid the undesirable condition above mentioned.

In order to maintain a tight fit between the valve head 29 and bore 19 the hollow head is rendered radially resilient and expansible by slitting the same transversely as at 31, andV by extending the port 30 the entire length of the hollow head. The diameter of the hollow head is normally slightly greater than that of the bore 19,.so that when forced into the bore the head is contracted slightly and maintains a resilient pressure against the wall of the bore. To insure the resilient reactive pressure between the coacting ports, a curved metal spring 32 is positioned in the hollow head 29 so as to expand the valve head, thereby .causing the latter to resiliently bear against its seat.

The valve 28 may be controlled by any appropriate means such as a handle 34 secured to an appropriate stem 35 fixed to the valve 28 and projecting from the end of the faucet. The combined faucet and shower head above described may be readily applied as a unit to standard bath tub fixtures already installed, merely by removingr the. old faucet` p from the pipe l2 and substituting the new.

and 8 is similar to that just described but is designed primarily for new installations. This fixture includes a cross pipe 12 for connection with the usual hot and cold water supply pipes 10 and 1l through the usual regulating valves 13 and 1li'.A The pipe 12 is in this instance provided with a special fitting 36 intermediate the ends thereof. A passage 37 through the fitting maintains communication between the ends of the pipe 12. The fitting is also provided with a cylindrical bore 19 for receiving the hollow head 29 of a valve 28 substantially identical with that hereinabove described. The interior ofthe head 29 is open to the passage 37 through a port 39.

The valve head 29 in this instance, has a port 30 through the wall thereof adapted to register with either of two diametral ports 20 or 21 leading upwardly and downwardly from the bore 19. The upper port 20' communicates through a pipe 22 with a shower head 23 and the lower port 21 communicates through a pipe 40 with the faucet 18 of a -bath tub 26'.

ports 39, 30', and 21 and pipe 40 to the faucet 18. By turning the valve through one hundred and, eighty degrees from' this position port 30 registers with port 20 and the water passes up through pipe 22 to the shower head. A small hole 4l through the wall of the valve head 29' at one side of port 30 permits water to pass slowly into pipe 22 or 40 when the valve is in the intermediate position. The operator will lind it necessary to shut oif both valves 13' and 14', and in so doing will avoid this leakage of water through the shower or tub. A tight fit is maintained between the valve head 29 and the bore 19 by radially slitting the hollow head transversely at 31 and longitudinally'as at 42. This modified form of valve as well as others may be substituted for the valve shown in Figure 4 and vice versa, since the speciicvalves described cally described without departing from or sacrificing the advantages of. the invention as dened in the appended claims.
