This invention relates to multiple valves and is designed more particularly for coutrolling the flow of fluid to an apparatus the operation of which requires tha.t different fluids shall be passed through the same successively, such as bakelite molds, water sof- 'teners und the like. For example, in moldi1'1g bakelite the material tq be molded is first heated and subjected 'to pressure and then cooled. T0 effect these operations live steam is passed through the jackgat surrounding the mold und forming a art thereof, the application of steam being continued for a length cf time suflicient to properl heat and press the material. At -the end 0 this operation the steam is cut ofi and water is passed through the jacket to cool the mold. The steam which is passed thr ough the jacket is dischaiged to a trap or other receptacle f rom which it inay be withdrawn for other purposes, such as -heating the building, und the water is discharged to the drain. After the cooling operation und before a subsequent heating operation t-he water must be removed from the mold. This is usually accomplished by admitting steam to the Jaeket und blowing the waternut of the jacket to the drain. These s'everal oferatioi1s are efiacted hy the manipulation 0 a pluralityof individual valves. F or the heating operation the steam inlet valve and the discharge valveleadihg to the trap must be opened und then closed. For

- the cooling operation the water inlet -valve and the drain discharge valve must be opened.-

pleted the water valve is closgd and the steam valve opened to permit the steam to pass through the jacket to discharge the water t0 the drain. If th'e blowing out operation is eifected immediately following the* c001ing vWhen the cooling operation has be'en com 0f t11e -wat er the drain valve is closed and thatrap va'lvpgopened, thus againeflect-ing the heating Operation. Noiggnly is the manipulation of these individuai valves a slow process .but the sequence of operation depends entirely upon the operator und it is Very easyto open or close the wron valves or valva and even if this;had no ot er undesirable result it 'would produce additional delay und loss of time.

the several contr0lling valves in a unitary structure with a valve actuating mechanism for opening and closing the valves in their proper sequence, an inlet valVe and an outlet valve being opened or closed upon each operation of the mechanism.

Oxie objectof the invention is to embody 7 A further Object 0f the inventidnis to provide such an apparatus in which the several operations will be'so controlled as 170 insure the prope1 sequence. A further' object of the invention is to pro vide such a valve mechanism which will be simple inits construction, easily und quickly operated and which will not be liable 120 get out 'of order.

Other objects of the invention will appear as the mechanism is described in detail.

In these drawings I have1llustrated 'one embodiment 0t' my invention und have shown a form of device adapted for gpg lication.

o! the type above described ancl the stem 43 of this valve extends upwardly above the extension 37 of the housmg und is arranged subabout tl1is valve the water will accumulatestantially in a radial line with the upp'er end of the water inletvalve so that when the main a'ctuating device has been moved to a position to open the water inlet valve the handle 26 will extend 0utwardly across the stem of the valve 42, and I have provided the handle 26 with a. depending ortion or cam gurface 44 so artanged that lt will engage the valve stem 43 and openthe valve 42, either at the same time thatthe water inlet va.lve is opened or immediately thereafter, so that both valves willbe opened and closed at substantially the'a same time. main waterpressure is exerted against the vlvka 42 und Should there be any leakage in the individual water inlet chamber but the' pressure threon will be so slight that there will nd t be any leakage about the main water inleflYalve. v

As has been stated, this val-ve is adapted as here shown foruse wxth water soitening ap- -paratus' of that type which employs an exchan'g base minerpl a.s the softening age x xt. When so used the hard water supplypipe W111 be connected with the individual steam inlet.

chamber und the regenerating solution o! brine I5ipe will be connected with the individual Water inlet chamber, inlet chamber will be comiected with the softener. The outlet pipe for the soft'ener will -be co'nnected with the main discharge chainber of the valveand the individual discharge 'chamber, here shown as leading t0 the trap, will be contxected with the servme line und the individual discharge chamber, here shown as leading to the drain, will be counected with thedrain. Thus upon the opening of what are here chara :terized s the individual steam inletl valve und the trap valve the hard water would fiow through the; softener to the service line und upon the opening of what are bete charcterized as the individual water inlet valve und the drain valve, thia salt solution would flow from tho softener to the drain. Upon the completion. of the reconditioning Operation the 'steam inlet valve and the drain vnlve would be opened v to permit hard water to flow through th'e softeuer to the drain and to wash' out the sah: solution, after which the drain valve; yvo uld be closed und. the trap Vl.lve openecl to restore the softening operation."

'While I have shown and descxyilled oxie em bodiment 'of my invention I wish' it to be understood that I du not desire to .be llrn ited to t-h6details thereof as variousmodifications may occur to a person skilled in the art.
