To all whom it may concern:

Be it known that I, DANIEL Hosvonn, a citizen of. the United States, residing at Cleveland, in the county of Cuyahoga and State of ()hio, have invented certain new and useful Improvements in Fluid-Distributing Systems, and dodeclare that the following 1s a full, clear, and exact description of the invention, which will ena le others skilled in the art to which it appertains to make and use thesame. V

My invention relates to a new system of liquid distribution, structed and adapted to operate, suhstantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1- is an elevation partially in section and more or less diagrammatic, as a Whole, of the gate valve mechanism and the associated valves, as hereinafter fully described. Fig, 2 is a more or less diagrammatic view of an installation or plant embodying my new -systern, as also hereinafter more fully descrilc ed.. I The system or installation thus shownis designed moreespecially for the distrihution of water under pressure, and may be employed on a'small or on a large scale with equal adaptability to conditions.

Aconnnon use of the invention is in connectionwith water supply for villages and towns, in which a reservoir or tank-T is adapted to receive and hold a supply of water under such head and pressure as will inaintain'the supply in the mains Whenthe pumping station or source of pressure ceases to do its work. Apunip orpumping station or its equivalent is, therefore, a necessary constituentof the system. The invention re sides between these two points, the pump P and tank T, and comprises what I prefer to call a long distance gate valve V, adapted to control the flow of liquid to the tank directly through or from the mains, and to its open or closed according as to whether there is to be normal or specially high pressure put u on the system. This arrangement of parts a so provldes for the direct discharge of the tank into the main past a check valve It in the same being conv v 7 7! s case pressure liy tne pump is diminished or v on falls 'relow the pressure due at the liqmd 1n the tank or reser for any'r to the head voir. This will appear more clearly hereinafter, and in connection with the said hydraulically operated gate valve V and check valve K. i employ the check valve G and three-way valve N, and pipe connections in which said valves sev ally are located.

At the letters of 2 ;re'shown a relatively small pipe L, which leads to the tank, and mains l, which, presumally, distribute the Water to the town, and said pipes ohviously would he of widely dill'ercnt proportic ns, but of course are open. one into the other, and the same proportion applios at the right of Fig. 2 with the tvrosizes of pipe M.

New, recurring to the operation of the eye te1n, il it be desired to increase the pressure in the main i e between the nine and the tanl; tea degree greater than the head due to the height'of the tank or reservoir will ailord, and at the same time permit of he tanlr or reservoir feeding into the main pipe should the pump fail to operate, 1 divide the main pipe at a point where the special high pres sure service is to stop into two paths including hy-path or pass B, which passes around check valve Kin the main line, and said valve is so arranged that it will close with any flow of the liquid toward the tank or rcservoir and open w a any flow of or away from In the,

the tank or resel voir into the mains secondary or by path l5 there is placed the sic-called long distance hydraulically 0 eratod gatc-valve This valve is normal y open for the flow of liquid in either direction, hutrnay be closed from any pre-arranged station having a three way valve N, and when closed the pressure main M from the pump to the valves V and K. may be raisedto the maximum, with the tank shut off. But should the pump fail, the mains will be supplied from tank or reservoir T through check valve K, even though the attendant at N should fail. to open the three way valve and thus open gate valve V.

cylinder 5 is mounted centrally above sonable' romptness when pressure uponposite sides of the pistonis equal, and t 0 opening of said-valve can only occur with excess pressure from beneath. Such excess pressure is through pipe F from the main and y way of by-pass H, while pressure over or upon piston C ls-through suitable piping 6 to main pipe M at any desired point, and at 'which oint a three-way valve N and a drain 7 are coated. In the pi e connection F I place a check valve G, an the by-pass H is a comparatively small pipe about this valve. This allows the liquid to flow from the tank or reservoir into cylinder J freely, but owing to check-valve G in the direct line 'and the relatively small pipe of the by-pass, the

liquid will flow from the cylinder to the tank or reservoir slowly, thus cushioning the action of valve piston C.

If the three-way va'lve N is at a position where the pressure'from the main pipe is shut ofi fr'om'cylinderJ and the drain 7 open,

there is no pressure on the top of the piston but exhaust from over said piston instead,

and owing to the pressure on the lower side of the iston through pipe F and b%pass H,

' the va ve Vshould e wide open. 40

ut if the three-way ,valve N should now be placed in such position. that the ressure from'the main pipe can enter the va ve cylinder J through pipe 6, the piston would be forced downward ue tothe excess area of the upper face of the piston and the said long distance valve'V would be closed. j

Presumably the check valve K and gate valve V are-locatedrelatively near to the reservoir orstank, while valve N may be at a 50 great distance therefrom.

Among the ad antages of the foregoing I may note first that, normally, the li uid has arr-unobstructed passage-way from t e tank ern'eservoir to the service lines but that both the artificially sustained pressure from the pump, and the back pressure'from the tank may be open to the mainat the same'time.

Secondly, that, in a system of water works for small towns and villages, it has been customary to have a. tank or reservoir at some high point, which was filled intermittently by means of a pump. Of course, the pres:

sure in the main piping could not in that case be increased higher than the pressure due to the height of the tank or reservoinwhich had its overflow, and in case of fire no additional pressure could be obtained. On the con trary, with my improved systemof valves and connections, the ressure in the main distributing pipes can e raised to an excess pressure in'case of fire or the like, dependent on the capacity of the pump, and at the same time leave the tank with a full head so that it will supply the-main piping incase the pump is shutdown and the operator. fails to 0 en the gate valve. Such excess pressure, 0 viously, obtained by the closing of gate valve V under. pressure upon piston 0 through pipe 6, with three-way-valve N open to the main, check valve K being closed also. Then in case the artificially sustained pressure is weakened below tank pressure, the

pressure from the tank will assert itself andsupply the main. I can, therefore, throw pressure into the main and into the tank at the same time by opening gate valve "V, as shown, and this is the normal working-relation, or I can cut oil pressure to the tank by closing valve V through pipe 6.

From the foregoing description it will be' understood that the pump is for any suitable water connections, and"that the tower or receptacle is an auxiliary to the system designed to be used more particularly when thepump fails to opeiate. In that case the water would flow past valve K even though valve V were closed, but such flow of water from the reservoir would open valveV through the line F if the drain valve N should be opened.

What I claim is 1. A system of fluid distribution comprising a pump and a reservoir and pipes operatively uniting said parts, a check valve in said pipes adapted to be forced to its seat by back pressure from the pump, a by-pass, a gate valve positioned in said by-pass, and a fluid controlled piston connected with said gate valve and normally under operativecontrol of the pressure from the reservoir to open said valve. 7

2. In water distribution, a set of pipes and a reservoir open thereto, one of said pipes having a check valve and a by-pass about said checkvalve having a gate valve to govcm the flow of fluid to the reservoir, and means to close said gate valve comprising a cylinder, a differential piston therein operatively connected, with said gate valve and pipes for the admission of water to opposite sides of said piston, one of said pipes havlng a three-way valve to control the flow of water on the larger side of said differential piston, and the other pipe having a check valve and a by-pass substantially as shown and described.

3. A system offluid distribution comprising a pump and a reservoir and service pipes operatlvely uniting said arts, a-check-valve whereby said gate valve may be closed by 1-0 in said pipes adapted to e forced to itsseat the pressure from within said service 'pliges. by back pressure from the pump, a. b '-.-pass, a In testimony whereof I sign this spec' cagate valve positioned insaid byass, a fluid tion in thep'resence of two witnesses 5 controlled piston eoimec'tedwit said gate DANIEL M HOSFORD .valve and normally under operative control of the-pressure from the reservoir to open Witnessesi, said gatevalve, and valved pi e connections E.
