HOMER E. DUKE, OF MARKLEVILLE, AND GEORGE W. PIERCE, OF ANDERSON, INDIANA. l
Application filed March 17, 1922. Sieral No. 544,548. up
To'all 'whom t may concer/n:
Be itlmown, that we, I-IoMER E. DUKE and GEORGE NV. Pinnen, citizens of the United States, and residents lof Marlrleville and Anderson, respectively, county of Madison and State of Indiana, have invented a certain new and useful Filtering Apparatus; and we do hereby declare that the following is a full, clear,`and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.
This invention relates to a means for ltering a liquid, and particularly is adapted to be associated with a pump and cistern for clarifying the water pumped from the cistern, and for purifying the same when desired.
The chief feature of the invention consists in the details of construction, whereby the device may be economically manufactured by preferably utilizing an ordinary drain tile; and another feature of the invention is the construction of the several parts of the device, whereby the same will be substantially similar to enable the same pattern to be utilized in the moulding of said parts.
The full nature of the invention will be understood from the accompanying drawings and the following description and claim.
'In the drawings, Fig. 1 is a side elevational view of a water system showing the invention associated with a cistern and a pump. Fig. 2 is an enlarged central sectional view of the vacuum filter construction. Fig. 3 isa top plan viewthereof. Fig. 4 is a transverse sectional view taken on the line 4 4 of Fig. 2 and in the direction of the arrows.
In the drawingslO indicates a source water supply, such as a cistern containing a supply of liquid 11. A pump 12, which is herein illustrated as a manually operable pump, is connected by the pipe 13 to the cistern, and said pipe 13 terminates beneath the level of the liquid or water 11. Herein the terminating end of the supply line 13 is provided with an enclosing partial vacuum filtering device, indicated generally by the numeral 14 in Fig. 1.
Reference will now be had to Figs. 2, 3 and 4, wherein the device indicated generally by the numeral 14 in Fig. 1 is illustrated in detail. In said figures there is lar, with illustrated a top plate or head 15 and a botl.
tom plate or head 16, stantially identical, the central portion. the bottom plate 16 is said heads being suhwith the exception of The central portion of showny imperforate, as
at 17, while the same portion in the top apertured to form a head or plate 15 is bearing 18. The bearing portion 18 receives the coupling 10, and said couplingis adapted to receive the threaded terminating end of the supply pipe 13 and the threaded end ofv a 4pipe extension 20, which extends from the top head 15 tothe bottom head 16 and terminates adjacent the bottom head. With the foregoing construction it will Vhe apparent that the same pattern from which the one head is cast or moulded may be `utilized in the formation ofthe other` head,
coupling 19 being inportion and beln'g cast in one instance the serted at the central integral.l In order exterior' surface of the .coupling may be tinned or otherwise prepared, and when so prepared, a perfect weld is securedV between the coupling 19 and the bearing or hub 18.
Since each of the heads 15 and 16 are simithe exception noted in the preceding paragraph, a further description of one will suflice for an understanding of 4the other. The head 15 is provided upon one face with an inwardly extending reinforcing flange 21, which flange herein is illustrated as tubular, and preferably annular and concentric with the annular boss 17 or 18. The head 15 adjacent the flange 21 is provided to receive a gasket orsealing means 23. Another and herein concentric and inwardly extending flangey 24 is provided, and -said flanges 24 and 21 provide la groove or seat for the'reception of a porous tubular member, herein illustrated as a cylindricalv to form a union, the
lwith a groove 22, and said groove is adapted rous standard drain tile 25. The groove forming ange 24 is elongated, and, therefore, not only forms a guide or retainer for the cylindrical porous tile 25, but also provides a guide for a second and concentric porous standard drain tile 26. The head 15 adjacent the iiange 24 is provided with a concentric groove or tile seat 27 which is adaptedl to receive a gasket or sealing means 28. The plate 15 upon its opposite face is provided with a reenforcing flange 29 which herein is illustrated as annular and is positioned opposite the fiange 24, and intermediate the tile seats.
' been previously applied, tol said heads.
i vide access Upon the outer tace of the head or plate and radiating from the hub 18 are a plurality of reeniorcing radial ribs or ins 30, each ed? which terminates4 in. a socket. 31. The socket 31 is centrally apertured at 32, and herein said sockets are in spaced rel1ation with each other about the periphery of the head, and said sockets are positioned at a greater distance from the center than the groove 27. v
It will be understood that a pair o concentric porous standard drain tiles 25' and 26 are positioned upon one of the heads 15 or 16 and the other head is then positioned adjacent the other ends of' said tiles, the several' gaskets or sealing means having A vplur'ality of tie rods or bolts 33 have their ends threaded, and said tie rods are adapted to extend through registering openings 32 in the two heads- The nuts 34 engage the threaded ends' oi" the tie rods and are adapted to `draw the ends together and serve to. close the ends of the tubular and porous tiles 2,6, and 25.` It will be apparent that theA rods 313 protect the outer tile 26 from `casual injury.` Y
If desired, the, space between the two tubular membersl may be filled with a purifying. agent orv cl'arif. ing agent, or a mixture of said agents. It', the water-isp ure and odorless, the single tile 26 or 25 Wi be suie-ent for efficient operation of the device. It the water is not odorless, charcoal may be used between two or more oit" the concentric tiles, and' said charcoal will remove the disereeable loder or taste. from said water. .T e porous tiles,l oi course, preventthe pas-k sage of, dirt, or other matters. carried in suspension by the water.4 It the water is impure, the S .ace between the twotil'es 25 and 2d may e supplied with a, chemical agent, which will purify the water in its passage from one, tile through the inner tile. The device. is so constructedjthat the parts may be readily disassembled to protoy the space betwen the. tiles -or renewing, when necessary agents, or means in the space between said tiles'.
The operation. of the device is as follows: n
Water is supplied through the pump supply line 13 to the inner chamber 36 to prime the apparatus., i The pump thereafter isvoperated and creates a partial vacuum in the chamber 36. This partial vacuum, since nature abhors a vacuumof any degree, by atmospheric pressure upon the water 11 in the cistern 10, which forces said water in said cistern through the tiles 26 and 25 into the chamber 36, in orderto overcome the difference in pressure existing kin the chamber and atmospheric pressure. as, the pump12 is operated, there will be a removal of: the water entering the chamber 36 from the cistern 101 When the pump has stopped operating, the water' in the line 13' runs baclr into the chamber 36 and re mains therein until the anced. Subsequent operation or" the pump produces a partial vacuum in the chamber 36, as hereinbeiore described, andthe operation of: the vacuum re eated. l
he invention claimed is:
A pair of similar supporting heads for aiilter construction formed from a pair of standard tubular 'of exteriorally positioned tiler rotecting and securing rods, each head inc I"uding on opposite faces axially projecting bosses, an annular reinforcement and centering ring projecting from one faceand concentric with the boss, the opposite Jface and concentric wi* both boss and first mentioned ring an of `a larger diameter than either, a tile seat concentric with the boss and both rings and upon the 'same face as the `first ring, and of a larger diameter than either ring, and radial ribs extending from the boss through the secondimentioned ringc upon that face' of the head and terminating inrod receiving apertured enlargements, 'the apertures extendingthrough the head for rod reception.
