2 claims. (ci. 12s-229) `the exact proportion desired'before the washing or irrigation begins.
It is the further object ofthisinvention to provide a device of thetype set forthwhich may bepermanentlymounted upon a wall or other support and which, when notk in use, maybe enclosed in such a manner as to present an attractive exterior appearance. f
The iurtherobjeet ofV this invention is to provide a device of the type set forth in which the proportion of hot and cold liquid employed may be set and allowed to remain permanently, sub ject only to resetting as and'when desired.
Another object of this invention is to provide a device of the type referred to in which the proportion of hot and cold liquid employed may be permanently set, together with a means whereby such proportion may be varied from the permanent setting temporarily without, however, disturbing the parts which determineithepermanentsetting. Another object or" this invention is to provide a device of the type set forth which may be lcontained within a cabinet having an attractive exterior appearance. v
With the above and other objects in view, one embodiment. of this invention is set forth in the accompanying drawings Vand the followingv description:
In the drawing: Fig. 1 is a vertical crosssection taken through a device constructed in accordance with this invention. Y
Fig. `2 shows a vertical cross-section through the same device but taken at. right angles lto Fig. 1. Y
Fig. 3 is a horizontal cross-section rof the same device taken along the line 3-3 of Fig-.2.
Fig. 4 is an enlargedview, partly in plan and Y partly Ain horizontal cross-section illustrating the mixing valve arrangement "as embodied in 'thisE invention and showing.v a slight modification of the form set forth in Figs.y 1, Zand 3.
Fig. 5 is a vertical cross-section through the central portion of the device illustrated in Fig. 4. Fig. 6 is a horizontal cross-section through the vliquid to lthis chamber.
device shown in Fig. 5 talen along the line 454-6 of Fig. 5.V
In theembodiment illustrated in Figs. 1, 2 and 3, the cold and hot liquid will be supplied to the device through suitable means such as the pipes I and 2. These two pipes are connected through suitable xtures tothe mixing valve 3. In Fig. 4, there is vshown arnodiication in which an'extra valve 4 is inserted in one of these lines and anr extra valve 5 in the other so that by Vmeans of these two valves the volume vand proportion of hot and cold liquid may be adjusted and set.
, The mixing valve 3 is of the plug type, the plug being in tapered form as shown at 6 and being controlled-by a handle l of conventional design. .This plug, asY shown in Figs. 4 and 5, is provided with a` channel 8 extending around the plug substantially two-thirds or more of its circumference.. Leading from the cold and hot supply into the valve plug chamber are passagewaysV 9 and le for conducting the cold and hot The channel 8 is arranged to register with the openings 9' and Il and also with an outlet opening Il from the said chamber, said outlet opening leading into a special T-iitting I2. It will be seen that when the valve 3 is in the Vposition shown in Fig. 4,-no liquid may flow through either the passage 9 or the passage ill into the passage Il and assuming that the pressure is-the same in the hot and cold supply, as it normally would be, there would be no iiow'whatever through the mixing valve 3.
.Ii the handle of this mixing valve 3 be now turned to the right. as seen in Fig. 4, the left end of the channel 8 would shortly begin to register With the inner end oi the passage II and liquidwould begin to flow into this passage il. There would be more liquid flowing from the liquid supply 2, however, than from the liquid supply I in such instance, because the liquid supply 2 would have a shorter distance to travel. Furthermore, at about theV time the passage II begins to register with the passage 8, the passage 9 would begin to be slowlycut ofi so: that more and more liquid would lcw from thesupply 2 and less and less from the supply i. If Vthe handle be turned still further, the passage B willagain be uncovered'and may be uncovered to such an extent that an equal amount of vliquid willow from each liquid supply. Y
In the mannerr justA related, any desired proportion of hot and cold liquid may be supplied to the passage II.
The T-tting I2 is provided with an outlet I3 adapted to receive a hose Ill and also with an upstanding portion I3', the upper end of which extends through the bottom I5 of a liquid reservoir within the cabinet I6, this reservoir being designated by the numeral I1.
The part I3 is secured within the opening in the bottom of the reservoir I1 by any suitable means, such as the customary lool; nut and gasket arrangement.
The cabinet I6 just referred to, in addition to the liquid reservoir I1 in its upper end, provides a compartment I8 in its lower end in which the hose I and other accessories may be stored. The front of this compartment I8 is provided with an opening I9, and the entire cabinet is adapted to be closed yby means of a cover pivotally mounted on pivots 2| carried by the side walls of the cabinet I B. The cabinet may be securely mounted upon a wall or similar support by means of bolts 22.
The reservoir I1 is provided with an overow pipe 23 so that when an excessive amount of liquid accumulates therein, it' will overiiow into the lower compartment. The lower compartment is formed with an opening 24 in its bottom wall so that any such overflow liquid may drain out. It is contemplated in this instance that the cabinet will be placed above a bathtub or lavatory or some similar receptacle which will serve to catch such overflow liquid, but it is within the purview of this invention to provide a special drain pipe for receiving such liquid and conducting it to a suitable place.
Referring again to the connection between the part I3 and the reservoir I1, it will be seen that a cap 25 is secured to the upper end of this tting and that this cap has lateral outlets 26 therefrom and an upper outlet 21. The outlet 21 is adapted to be closed by an upwardly movable valve element 28 carried within the cap. This valve element, when moved to its upper position, will close the opening 21, but is incapable of moving down far enough to close oif the part I3 against lateral ow through the outlets 26. In order to guard the opening 21 and to prevent any spray or jet upwardly through this opening which might pass out of the top of the reservoir I1, there is provided a guard 29 over the opening 21.
The hose I 4 may be closed whenever desired by any suitable clamping device 3U, and carries on its free end a nozzle 3l of any desired characteristics.
In operation, if the modification shown in Fig. 4 is employed, the miinng valve 3 may rst be turned so that both hot and cold liquid supplies are wide open. The valves 4 and 5 may then be adjusted until the liquid being supplied to the nozzle 3| is of exactly the desired temperature. This adjustment need not be disturbed unless and until it is desired to change the temperature of the liquid supply to the nozzle, or unless and until the temperature of the hot or the cold supply changes. In this form, the valve 3 may then be used simply as a cut off Valve by turning it either to fully open or fully closed position as desired, or it may be operated as a proportioning and mixing valve to Vary the temperature of the liquid supplied to the nozzle from that for which the valves 4 and 5 have been set. This latter variation would of course not disturb the setting of the valves 4 and 5.
-through the openings 26.
For the purpose of adding a medicament to the liquid supplied to the nozzle, a liquid supply may rst be introduced into the reservoir I1 by simply closing the shut off 30 and opening the liquid supply to fill the reservoir I1. When the required amount of liquid is in the reservoir I1 the medicament may be added and mixed, the liquid supply being shut olf in the meantime. During the flowing of liquid into the reservoir the valve 28 will be forced upwardly to close the valve 21 and prevent the spraying or jetting of high pressure liquids out through the top of the reservoir. The liquid will enter the reservoir When the liquid is drawn from the reservoir to the nozzle, the valve 28 will move away from its seat, thus permitting free flow of liquid from the reservoir.
One other function of the reservoir I1 is that if it be desired to supply liquid from the liquid supply directly to the nozzle, and the liquid from the liquid supply flows slightly faster than the nozzle can dispense the liquid without increasing the pressure, the excess liquid may flow up into the reservoir, the same serving in such instance as a surge chamber.
When not in use, the hose I4 and the nozzle 3'I together with other possible accessories may be stored Within the `compartment; I8 and the cover 20 raised to completely enclose the various parts and providing a neat and attractive exterior appearance.
It will be seen from the foregoing that a device has been provided which is capable fully of carrying out all of the objects hereinabove set forth with respect to its utility, and which, when not in use, may be entirely enclosed so as to present a neat and attractive appearance.
