w shower or to the tub, as the user may require.

I am aware that heretofore various forms of.

valves have been constructed and used for a similar purpose, that is, for directing the iiow of water either to a shower bath or to a tub. In these structures, however, it isnecessary not only to operate the valve to deter-V mine the path through which the water will flow but also to positively operate the valve to return the same to its initial position. Be-

cause of this condition and the forgetfulness of the user the valve may not be returned but left in one position or another, for example, the valve may be shifted to the shower and allowed to remain in this position when normally it should be so placed that the Water will How to the tub. Obviously in such instances when the Wat/er is turned on it is sent through the shower unexpectedly, and the user being unprepared for this may either have the Water diverted over the sides of the tub, or the water will wet the clothing, or there may be other unexpected results before the valve can be turned to a position in which the water flows to the tub as intended.

The object of my invention is the provision of a valve so constructed that in the use there of a passage to the tub or other fitting is normally open and a passage to the shower, or other fitting, is normally closed. In the use of the valve when it is desired to direct the flow of the water to the shower or other fitting rather than to the tub the valve may be operated by suitable devices causing the valve to move to close the passage to the tub and open the passage in the shower. Furthermore, the construction is such that with the valve moved to the shower position the water pressure automatically maintains it in place causing the water to continue to :How to the shower or other fitting independently of the valve operating -devices until the water is shut olf. When the water pressure is relieved the water in the line to the shower or other fitting is permitted to flow to the tub and in so doin tends to return the valve to its initial positlon until the head of water in the shower line has entirely escaped, and then the valve and its operating devices are automatically returned to their normal or initial position in which the passage to the tub is open and the passage to the shower or other fitting is closed.

The transfer valve made in accordance with this invention will be hereinafter more particularly described in conjunction with the drawings in which Figure 1 is a front elevation illustrating the use of the transfer valve,

Figure 6 is a sectional elevation illustrating the use of the apparatus.

Referring to the drawings the 'transfer valve made in accordance with this invention and as illustrated is constructed to include a valve body 10 having oppositely ,disposed preferably lateral inlet connections 11 and12, the former of which may be 'connected by a pipe 13 to a valve 14 in the pipe line 15 for l hot water while the inlet connection '12 may be similarly connected by a pipe 16 to a valve 17 in a cold water pipe line 18. It will be understood, of course, that the pipe lines 15 and 18 are connected respectively to any suittable source of hot and cold water supply. These inlet connections 11 and `12 communicate with the chamber 19 within the valve body. Also in communication with this chamber 19 there is an outlet connection 20 preferably on the upper side of the valve body and with which a discharge pipe 21 is connected and also an outlet connection 22 preferably o n the underside of the valve body and to which there is secured a plug connection 23 for making communication with a second discharge pipe. As illustrated, in order to -make a tight joint a gasket 24 is employed between this plug and the face of the outlet connection 20. Also fitted on the plug there is a nut 25 adapted to connect the flanged end of a pipe 26 to the outer end of the plug with an intervening gasket 27 or otherwise. The discharge pipe 26 is adapted to lead to a bath tub spout 26 or similar fixture while the discharge pipe 21 is adapted to be connected to a shower bath or spray 21 or other similar fitting, as shown in Fig. 6.

In a suitable position in the valve body 10 there is Vtransverse wall 28 having an opening or port centrally disposed therein and provided with a valve seat 29. The inner end of the plug 23 is provided with an internal ange 30 providing for an opening or port therethrough and asimilar and oppositely disposed valve seat 31. Operating in the valve body I employ spaced valve members 32 and 33. These may be similarly formed and made of any suitable material. As illustrated they are mounted in spaced positions on a valve stem' 34. The valves are horizontally disposed andsuitably secured on the valve stem. The valve stem is vertical, the upper portion of which passes through a bearing provided therefor in an internal bracket 35 in the valve body. In like manner the lower end of the valve stem 34 passes through a bearing provided therefor in an internal bracket 36 in the plug 23. The valve 32 is adapted to bear against the valve seat 29 to close the port controlled thereby and shut ofl` the flow of water or other liquid from the chamber 19 to the discharge pipe 21. 'Vhen the valve 32 is in this position the valve is raised an appreciable distance from its seat 31 whereby the chamber 19 is in open coinmunication through the plug 23 with the dischar e pipe 26. Conversely when the valve mem er is shifted to the position in which the valve 33 bears against its seat 31 the passage is closed to the pipe 26 and the passage is open to the pipe 21 whereby, for example, the flow of Water is shut off to the tub and is open to the shower.

The Valve body is constructed to include a head 37 through which there is a passage 33 communicating with the chamber 19. 'llu` passage 38 is closed by a cover 39 fitting over the same and being secured to the head. This cover 39 includes a tubular extension or sleeve 40. As illustrated the cover and its sleeve ma be connected to the head of the valve bo y by means of suitable screws 41 or otherwise. Passing through the sleeve 4() and into the chamber 19 I employ a valve rod 42. At one end this valve rod constructed (o include a crank or ofl'set portion 43 and a pin connected thereto in a position eccentric to the valve rod.

The pin 44 extends into the same against its scat 29.

space between the valves 32 and 33 to operate the valve device, as will be hereinafter more particularly described. At its outer end the valve rod 42 is connected to the handle 45 by means of a stud bolt 46 or otherwise. As illustrated the end of the sleeve may be recessed or cut-away, as indicated at 47, and that portion of the handle fitting over the valve rod may be similarly recessed, as indicated at 48, whereby the revoluble movement of the handle is limited and determined by the extent of these recessed or cut-away portions.

The inner end of the valve rod 42 is provided with a set of flanges, indicated at 49, 5() and 51. These flanges are suitably spaced and the central flange 50 is preferably of an appreciable greater diameter than the adj acent fiang'es 49 and 51 on either side thereof. Mounted on the valve rod 42 and associated with these flanges I employ gaskets 52 and 53, the construction being such as to make substantially a water tight joint without causing sufficient friction to prevent the automatic return of the valve and its operating devices to their normal position. The inner portion of the gasket 53 lies in the space between the flanges 50 and 51, while its outer portion is clamped between the face of the head and the adjacent portions of the cover 39. The inner portion of the gasket 52 lies between the flanges 49 and 50 While the outer portion thereof lies between the outer face of the fiange 50 and the base of a recess or socket provided therefor in the cover 39. It will be noted furthermore that the cover 39 is provided with a recess of a. diameter substantially the same as that of the flange 49 and in which the flange 49 fits.

As illustrated, the valve and the parts associated therewith are placed at the rear of a wall 54 so as to be enclosed and concealed in accordance with present plumbing practice. However, the apparatus may be used in a construction in which the parts are not concealed. In the structure as illustrated, however, the Wall 54 is provided with an opening 55 through which a part of the valve projects. Normally this opening 55 is covered by an escutcheon 56 secured in place by a collar 57 having a flange 58 fitting into an opening in the escutcheon, and the collar, as illustrated, is fixed in position on the sleeve 40 by means of a set screw 59 or otherwise in order to maintain the escutcheon in position to cover the opening in the wall to conceal the parts of the valve.

In the use of the transfer valve, as hereinbefore described, the. parts normally assume an initial position which is that illustrated in Figure 2. In this position the handle 45 is vertical and the valve rod 42 is so placed that the pin 44 is in its uppermost position Wherein it engages the valve 32 and maintains the ln this position the stood, if either one or both of the valves 14 and 17 are opened water will flow to the chamber 19 and pass to the plug 23 and thence through the discharge pipe 26 to a tub or other fixture. Furthermore the water will always flow through the pipe 26 unless the user intentionally operates the valve. When it is desired to transfer or divert the water to the shower the handle 45 may be turned a partial revolution in either direction where# upon the pin 44 will be caused to move downwardly to contact with and assist the action of gravity in forcing downwardly the valve device to seat the valve 33 against the valve seat 31 thereby closing the port to the .pipe 26 and opening the passage normally closed by the valve 32 and permitting the water to low through the pipe 21 to the shower. It will also be understood that due to the pressure of the water it is unnecessar for the user or operator to hold the handle 1n the position to which it has been moved to shift the valve, the water pressure being sulicient to maintain the valve 33 against its seat 31 whereby while the water pressure'is m'aintained in the chamber 19 under these conditions the water will continue to flow to the pipe 21 and thence to the shower. Furthermore, when the water is shut ol and the service pressure thus relieved in the chamber 19 the head of the column of water in the pipe 21 will create a suliicient pressure to prevent the valve member from entirely returning to its initial position until this head of Water is permitted to escape to the tub by way of the pipe 26 whereupon due to the weight of the handle and the section of gravity the same returns to a vertical position and in doing so lifts the valve device returning th'e parts to the position as illustrated in Figure 2 which action is entirely automatic as will be readily understood. It will now be apparent also that when the water supply is shut off there will be no ressure other than that of the atmosphere 1n the chamber 19 of the valve body 10 and that this condition lends to the ready automatic return of the handle, the valve rod and the valve members to` their initial normal positions after having been operated. Still furthermore, it will be understood that when it is desired or necessary the handle may be. manually operated while the water is passing through the transfer device in order to shift or transfer the passage of the water either from the shower to the tub or vice versa. l
