MULTIPLE OPERATING VALVE.

Application filed June 28,1923. SerialNo. 645,404..

To all whom it may concern Be it known that I, a citizen .o'fthe United States, and resident of Pittsburgh, in the county ofAllegheny and Stateof Pennsylvania, have inventeda new and useful Improvement inMultiple Operating Valves; and I do hereby declare the following to be a full, clear, andexafct description thereof.

My invention relates to apparatus for operating hydraulic valves controlled from adistance in filtration or other plants where a device of this kind is applicable.

The present form of apparatus generally employed consists of a large, expensive table usually provided with a marble top on which the "operating-handles which connect pressure to each four-way valve,

up to four-way valves inside the table are disposed, which in turn are connected to the manifold header supplying water and carrying away thedrain'from thenn The fourway valves in turn are connected up to each end of the cylinder of the hydraulic valve and the pressure and drain line of the marsh This construction requires a fold.

handle for. each valve, and the object of my invention is to eliminate the ,useof such a large I table with the individual four-way valves larged View of a portion of' the top indicating plate. I

In the drawing the numeral 2 designates a suitable stand or pedestal. Resting on said stand 2 is the valve casing 3 provided with the'v'alve- chambers 4 and 5. Within the'valve- chambers 4 and 5 are the valves 6 and 7, respectively, said valves being 'of pistonform fitting snugly within the valvechambers, and provided with the stems 8 which pass up through the top-plate 9 of I the valve casing, and throughstuifing boxes 10. Pinions 11 are mounted on the outer ends of the stems 8, and said pinions mesh with the central pinion 12 mounted on the vertical shaft 13, said shaft being journaled FREDERICK B. LEOPOLD,-

gate-valve 26.

while only one gate-valve is illustrated there under at its lower end in theboss 14, andthe up per end of said shaft entering the socket-15 in the lever-handle 16. Itwill be apparent that when the lever 16 is moved a rotary motion will be imparted to the pinion 12 and, through said pinion, to the pinions 11 and valves 6 and 7 connected thereto.

The valves 6 and are provided with the ports 17 and 18, and said. ports are adapted to be brought into register with ports 19 and 20 in the bottom-plate 21 of the valvecasing. Pipes 22 and 23' connect up- tothe ports 19 and 20, respectively, the pipes 22 leading to the lower end of the cylinder 24, while pipes 23 enter the upper end of said cylinder. The piston 25 of the cylinder 24 is connected up to a gate in the ordinary It will'be understood that will be gateivalve 9 19 11 0f Pipes 22and 23." I. g

Ports'27'and 28' formed int he valve cas- 111g. communicate with the valve chambers.

4 and 5, and said ports are controlled by an ordinary plug-valve 29 which is operated-by the handle 30. Fluid pressureisadmitted by the pipe 31, and the fluid isdirectedflby the valve 29 either through the port 27 or 28 according to the position of the valve 29.

. Ports 32 and 33 also lead into the valvechambers 4 and 5, and said ports are controlled by a plug-valve 34 which opens and closes communication'between said ports and the drain-pipe 35. Theplug valve-34 is op,-

erated by a handle similar tothe'handle 30..

A hood 36 rests on the stand 2, and said I I hood encloses the valve-casing and other parts above described.

Formed integral with the socket-portion 15of the operating lever 16 are the indicator fingers 37, each of which bears alegend. designating one of thevalves of the system. By moving the lever16 the fingers 37 are brought into register'with the point 38 on the hood 36, when any one of the valves corresponding to the legend is to be op.--

erated. 1

Mounted onthe top of the hood 36 are in-.

dicator plates 39 and 40, one for fluid pressure supply and one for the drain.

In the operation of the device, the main lever 16 is rotated to the point indicating the valvefthat it is desired to operate, thus 1 bringing the ports 17 and 18 of the valves 6 and 7 over the corresponding openings 19 and 20 leading to the top and bottom of s the hydraulic cylinder of the valve to be operated.

If it is desired to open the gate-valve 26, the handle of the drain valve is positioned as shown in Fig. 4, so that its notch is atopen" position, while the pressure valve moved 180 from the positon shown in said figure, until its notch is at open position. The water will then enter the chamber a through the inlet port 2? under pressure and will pass by the port 17 and pipeQQ to the lower end otthccylinder 24. illhe gate valve will be raised and the water contained in the upper part of the cylinderfl l will pass up through the pipe into the valve chamber 5 and thence by the port 38 to the drain pipe To close the gate-valve 25 it is only necessary to turn the drain valve to closed position and turn the pressure valve to the position shown in Fig. 3, when the reverse action will take place, the pressure being applied to the top of the cylinder 2% and the bottom being connected up to the drain.

I claim as my invention:

1. Valve structure c inprising a valv casing having a pair of valve chambers therein, a plurality of annularly arranged ports in an'end wall of each of said chant hers, alluid pressure port and a drain port in the side wall of each of said chainhers,a rotatable valve disc fitting against the end wall of each of the chambers and having a port positioned to register with said annularly disposed ports sucessively, each of the annularly arranged ports in one chamber having paired relation with the port in the other chamber, means for rotating said discs in definite relative relation, a source of fluid pressure, a valve for eflect-ing coinunication between said source and said pressure ports selectively, and a valve for opening and closing said drain ports selectively, means disposed exteriorly of the casing, for rotating said disc, and means disposed exteriorly of the casing 'for operating said valves. s

2. Valve I structure comprising a valve casing having a pair of valve chambers therein, a plurality of annularly arranged ports in an end wall of each of said chambers, a luid pressure port and a drain port in the side wall of each of said chambers, a rotatable valve disc fitting against the end wall of each of the chambers and having a port positioned to register with said an nularly disposed ports successively, each of the annularly arranged ports in one chamber having paired relation with a port in the other chainber, means for rotating said discs in definite relative relation, asource of fluid pressure, a valve for effecting co1nniunication between said source and said pressure ports selectively, and a valve for opening and closing said drain ports selectively, the said disc rotating means and the said valves being connected, to operating handles that are mounted upon the top of the casing. I v i In testimonywhereof I, the said FRED- anion B. IIEOPOLD, have hereunto set my hand. 7 I
