SIPHONIC AND COMPRESSED-AIR SYSTEM FOR CONVEYING LIQUIDS.
SPECIFICATION forming part of Letters Patent No. 413,194, dated October 22, 1889. Application filed January 30, 1389. Serial No. 298,049. (No model.)
To aZZ whom it may concern:
Be it known that I, J OHN KISER Lnnnv, a citizen of the United States, residing at Toms Brook, in the county of Shenandoah and State of Virginia, have invented certain. new and useful Improvements in Siphonic and Oompressed-Air Systems of Conveying Liquids, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to an improved siphonic and compressed-air system for conveying liquids; and it has for its objects to convey a liquid from any suitable point or source to various points of distribution, as more fully hereinafter set forth, and specifically pointed out inthe claims.
The above-mentioned objects I attain by the means illustrated in the accompanying drawings, in which" Figure 1 represents a vertical sectional view showing my invention as applied in practice. Fig. 2 represents a vertical sectional view showing one of a system of storage vessels or tanks forming part of my invention 5 and Fig. 3 represents a detached sectional view of a valve and protective chamber, through which the fluid is supplied to the storage tanks or vessels, as more fully hereinafter set forth.
Referring to the drawings, the letter A indicates the source of supply, which may consist of a tank, reservoir, or running stream, located, preferably, at an elevation above the .level of the final point of distribution, the
said level being indicated in Fig. 1 of the drawings by the dotted line 05 00. From the said source of supply extends a pipe or conveyer B, through which the liquid may be passed to the various points of delivery.
The letters O O O C indicate a series of storage tanks, vessels, or reservoirs, forming part of my improved system. The said tanks or reservoirs are located at any convenient points in the line of distribution of the liquid and are connected with the distributingpipes, as more fully hereinafter explained. The said tanks are partly constructed of masonry and partly of metal or other suitable material, as indicated in Figs. 1 and 2 of the drawings, in which the letter 00 indicates a cylindrical or other shaped vessel of metal or other suitable material, and b a cylindrical the purpose hereinafter explained.
or other shaped structure constructed of matherein in such position as to leave an intervening space, which is filled with a plastic cement c, of such nature t-hat'it can be run into the space while in a fluid condition, and which will afterward harden and solidify, so as to form a compact wall for the support of the vessel a and strengthen it, against internal pressure, and render it perfectly air and water tight.
The vessel a in each case is provided with a central opening or man-hole at the top, on which is fitted a removable cover d, by means of which access may be had to the interior for the purpose of cleaning or repairs. The mouth or opening of each of the structures 1) is provided with a removable cover 6, by means of which access may be had to the interior thereof.
The letter D indicates a tank, reservoir, or compressed-air supply, from. which extends a pipe E, which follows the general line or route of the liquid-distributing pipe. The first storage tank or reservoirO of the system is connected with the said air-pipe E by means of a branch pipe 9, which is provided with a stop-cock h, by means of which compressed air may be supplied to said tank. The second tank O in the system is connected with the liquid-distributing pipe B by means of a branch pipe 1, which is provided with a stopfcock 7e and extends down into the inner vessel thereof, to near the bottom of the same, where it is bent substantially at right angles and turned upwardly, terminating in a perforated globe or vessel on, in which is located an auto1natically-acting check-valve n, for The said pipe 1' is also provided with a short branch pipe r, which has a valve r controlled by a valve-rod a), adapted to be operated from above, to permit the water to be passed from the inner vessel of the tank 0 into the pipe 2', and from thence to the pipe B, to start the siphonic action therein, as more fully hereinafter set forth. 7
From the inner vessel of the tank 0 extends a pipe S to a suitable point above ground, through which the fluid from said tank may be discharged for use when required, the said pipe being provided with a cook or valve to, for starting or stopping the flow of water therefrom.
The tanks 0 G with their connections, are dupl cations, respectively, of the tanks (3 C, and are arranged in the line or route of the system of distribution. From the tank 0 the distributing-pipe B passes above the level line 00 00, over the elevations due to the natural formation of the country on the line of the system, and terminates in a final reservoir G below the level 00 as, in such manner that the liquid in its final discharge from the pipe B will collect in said reservoir G and seal the terminal end of the pipe B against the admission of air into the same.
To put my improved system in operation, the liquid is first allowed to flow from the source A through the pipes B and branch pipe i into the inner vessel of the tank 0, the valves B, B", and It being left open, the liquid entering the tank 0' by its own gravity, liftin the automatic check-valven in its course. \Vhile the filling operation is taking place the confined air in the said tank passes off through the pipe t and valve a in the branch leading therefrom, the valve being opened for the purpose. hen the tank 0 has been filled, the valve n is closed and the valve 10 opened, permitting the compressed air from the compressor D to enter the tank 0 through the pipe 25, creating any desired degree of pressure therein. The pressure automatically closes the check-valve n, and the fluid, having no open outlet, is held in said tank 0'. \Vhile in this condition under pressure the liquid maybe drawn off for use above the tank 0 by opening the valve a. To start the siphonic action in the elevated portion of the main pipe B, the valve 1 is opened by means of the valve-rod o, the valves B B" being closed and the valves B and it opened. The pressure in the tank G forces the liquid forward into the elevated portions of the pipe B, passing the valves B B' and the valve 79 of the pipe t', leading to 'the tank 0 filling the said tank and the reservoir G, the air in said tank being allowed to pass off through the pipe t, leading therefrom, and the valve a \Vhen the tank 0 is filled, the valve a is closed, the valve 10 is opened, and compressed air is admitted to the tank The liquid may be then withdrawn from said tank through the pipe S by opening the valve 10 thereof. Should the waterin the reservoir G become exhausted by any means, it may be readily supplied from the tank C closing the valve B and opening the valves 71) and 0*, when the pressure in the said tank 0 will effect the purpose.
The tanks 0 and 0 provide for the storage of compressed air at convenient points along the route of the system, the air being passed into said tanks through the pipes g, leading from the pipe E, extending from the 001m pressor, by opening the cocks h. WVhen suf-- ficiently compressed, the air may be retained in said tanks 0 and C by closing the cooks h, and supplied for use to the tanks 0 and 0, when required, by opening the said valves h again. When it is required to clean the air-tanks or to enter the same for repairs or other purposes, the compressed air therein may be allowed to escape through the pipes h by opening the valves 7Z2 thereof, and the covers of the man-holes of the vessels a and the structures I) removed.
It is evident that any number of air and liquid storage tanks maybe employed in connection with my improved system of distribution, so long as the relative positions of the supply and delivery points are maintained, without departing from the spirit of my invention.
My improved system of distribution may be employed for various purposes, such as supplying water along a line of railroad, in cities and towns for furnishing water under pressure for extinguishing fires, and in all other instances where it is desired to have a fiow of water or other liquid under pressure.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
1. The combination of a liquid-supply, a liquid-conveying pipe connected to this liquid-supply, buried liquid-storage tanks connected to the said conveyer by means of valved pipes, valved supply pipes leading from these buried storage-tanks to the sur face of the ground, and a discharge-tank G, located below the level of the said liquid-supply, the discharge end of the conveyer being submerged in this tank, as and for the purposes herein set forth.
2. The combination of a liquid supply, buried liquid-storage tanks connected to the said liquid-supply by means of valved pipes, valved discharge pipes leading from the buried liquidianks, compressed-air-storage tanks buried beneath the surface of the ground, and a main compressed-air conveyer connected to these tanks and theliquid-tanks by means of valved pipes, substantially as and for the purpose herein set forth.
In testimony whereof I affix my signature in presence of two witnesses.
JOHN K. LEEDY.
