LUIDEORD C. JNES, 0F BALTIMORE, .ll/LARYLANID.
VALVE MECHANISM FOR LQUIDS.
Specication of Letters Patent.
Patented Au. 9, 1910.
Application nien November 15, 1909. Serial No. 527,972.
To @ZZ whom it 'may concern: y
Be it known that I, LUDFoRn C. Jonas, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Valve Mechanism for Liquids, of which the following is a specification.
This invention relates to an automatic valve-mechanism for maintaining a pre-determined height or quantity of Water in a storage tank or reserv`oir, the stored water being continuallyconsumed or used.
The invention is illustrated in the accompanying drawing, but it is not to be understood that the claims appended hereto are limited to the recise construction or arrangement of parts" shown in said drawing.
Referring'to the drawing the letter, A, designates the tank or reservoir that is to contain a storageof water; B, designatesthe main pipe that supplies water to the said tank; C, designates the case of a valve that governs ythe flow of water through said ma1n-p1peg D, 1s a case 'containing a floatball; and,V F, is a case containing auxiliary valves that are operated the up-and-down movement of the said float-ball.
The tank, A., may be of any size and any material, and is designed to contain a` storage of water that is continually being used or consumed, and the object of the valve-mechanism which is the subject of this invention is to so regulate the supply of Water to this tank as to maintain therein a lpre-determined height or quantity of the Water. The pipe, l, leads from a source of supply tothe said tank and the valvecase, C, in this pipe has a main-valve, l, which is of the puppetform, that closes against the pressure of the water coming through the said pipe. The stem, 2, of this valve is movable through and neatly tits in a neck, 3, of the valve-case and said stem is attached to a flexible diaphragm, 4, whose rim is tightly clamped between the two convex plates of the metal chamber, 5. The diameter and area of the diaphragm, 4, is greater than the diameter and area of the face of the valve, 1.
The case, D, is outside oit' the storage tank and may be supported in position by any suitable means. An u per pipe, 6, connects this case with the tanli, A, and serves'as a vent, and a pipe, 7, connects the same below and serves to supply water; both pipes are prm'idcd with cutfotlE cocks designated respectively, 8, 9. This case, D, contains a `20, taps through the outer convex main valve, 1, and cut-0H the iow oli-Water through-the pipe, B. The water in the tank,
A, of course stands normally, as indicated by a horizontal broken line at the same height gs the water in the float-case, D, indicated Auxiliary valves are in a case, F, which is in communication through a tube, 14, with the case, l), containing the float; this auxiliary valve-case has a passage at the opposite ends ot' which are valve-seats, and two small valves, 15, and, 16, which are separate from each other, are employed, one valve being at'each seat, and the said two valves are so arranged that when one is open or unseated, the other will be closed or seated. This action of the valves is brought about by having the ends of the wing-stems, 17, ot' the two small valves abutted against each other, and as the length of these two wingstems, 17, together is greater than the measurement or space between the said two valve-v seats, it is impossible for both valves to be seated. at the same time. The small valve, 16, that is nearest to the tube, 14, which con'nnunicates with the loat-case, D, has a rod or stem, 18, which extends through said tube and is attachedy by a joint,` 19, to the float-lever, 11, whereby any up or down movement of the ball-iioat, 10, will seat or unseat said small valve, 1G.
A pipe, 20, hasone' end tapped into the side of the auxiliary valve-case and opens into the passage between the said two small valves, 15, 1G, and the other end of this pipe, plate of the metal chamber, 5. Another pipe, 21, forms a coinnninication between the outer end of the said auxiliary valve-case, F, and the main lsupply-pipe, l5,A at the inlet side of the main valve, C.
It will be seen that when the ball-lloat has i'ts up or raised position the small valve, 16, that governs communication between the iioatmase, l), and theV passage in the auxiliary valve-case, l?, will be closed, and the other small valve, 15, will be opened. l"vlfhen the valve, 15, open or unseated a water communication tablished 'from 'the main supply-pipe, "i1, through pipes, Q1, and, 23.0,
to the outer side of the fiexible diaphragm, 4, as seen in the drawing and of course there will be the same pressure in the convex chamber, 5, on said diaphragm as there is in said main pipe, and the edect of this pres sure will be to keep the main valve, l, on its seat in closed position because the diaphragm, 4, has a greater area for waterpressure than the main valve itself.
When the ball-float, 10, is lowered, the positions of the two small auxiliary valves will be changed or reversed from 'that last described-the valve, 16, will then be unseated or open, and the other valve, l5, will be seated or closed. The closing of the valve, l5, at the outer side of the open end of pipe, 20, cuts ott the pressure that comes from 'the main ipe, B, through pipe, 21, and the openin o the valve, 16, between said open-end o pipe, 20, and the tube, 14, allows some of the water in the pipe, 20; to escape into the auxiliary valve-case and'pass therefrom through tube, 14, into the float-case, and the effect will be to remove practically all pressure from the diaphragm, 4, and vthereby allow the main valve, l, to open.
Having thus described my invention what I claim and desire to secure by Letters Patent is,- l
l. In automatic mechanism for controlling the ow of liquid, the combination of a storage tank; a main supply-pipe rovided with a main-valve 'that governs the gow of liquid; a chamber provid-)ed with a movable dia-` phragm which is connected with said mainvalve; a float attached to a pivoted lever; an auxiliary valve-.case havin a passage provided at its two opposite en s with valve seats; two separate auxiliary valvesone being at each of said seats and/provided with stems that loosely abut so that only one of,
said valves can be seated at the same time; a rod jointed to the lever of said float and serving to seat and unseat one of said two auxiliary valves; a pipe one end of which taps into the auxiliary valve-case between. said two auxiliary valves and the other end of said pipe opcnin into the said diaphragm chamber; an a pi e communicating between the auxiliary va ve-case andthe main supply-pipe.
2. The combination of a storage tank; a main supplyepipe provided with a mainvalve; a oat Iattached to a pivoted lever; an auxiliary valve-case having a passage at the twoopposite ends of which are valve seats; two auxiliary valves-one being at each of said seats and provided with means whereby only one of said valves can be seated at the same time; a rod jointed to the lever of said float and operating one of said two auxiliary valves; and two pipesone connecting between the auxiliary valvecase and the main-valve case, and the other between the auxiliary valve-case and the main supply-pipe.
3. The combination of a main supply pipe; a valve in the line of said pipe to govern the flow of liquid; a chamber having a movable diaphragm, which is connected with said main-valve; an auxiliary valvccase havin a passage at the two opposite ends o which are valve-seats; two auxiliary valves-one being at each of said seats and provided with means whereby only one of said valves can be seated at the same time; a pipe one end of which taps into the auxiliary valve-case between said two auxiliary valves and the other end of said pipe opening into the said diaphragm chamber; a pipe communicating between the auxiliary valve-case and the main supply-pipe; and means to operate one of said auxiliary valves.
In testimony whereof I aflix my signature in presence of two witnesses.
LUDFORD C. JONES.
