LYMAN SMITH, OF KANSAS CITY, MISSOURI.
ECCENTRlC-SHAPED FILTER.
SPECIFICATION forming part of Letters Patent N o. 268,304, dated November 28, 1882.
Application filed November 4, 1882. (No model.)
To all whom it may concern:
Beit known that I, LYMAN SMITH, of Kansas City, in the county of Jackson and State ot'Missouri. haveinven ted certain new and useful Improvements in Eccentric-Shaped Filters; and I do hereby declare that the following isa full,clear,and exactdescription of theinvention, which will enable others skilled in the art to which it appertains to make and, use the same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form part of this specification.
The object of this invention is toimprove, simplify, and cheapen the construction ofdouhie-chambered filters, in which the water or other liquid is forced upward through sand or other filtering material; and itconsistsin certain novel"featnrcs, which will be hereinafter fully described, in reference to the accom pan ying drawings, in which Figure l is a vertical diametric section of a double-cham bered filter constructed accordin g to my invention, and Fig. 2 is a transverse section of the same on the broken line so a: of Fig. 1. Fig. 3 shows a vertical section of the eccentric-shaped filter castin one piece.
The letterA indicates an annular casing composed of two halves, a a, joined together by flanges and bolts, as shown at bb. The inner wall, 0, of the casing is eccentric with relation to the outer wall, a, so that the'space between these two walls is vertically wider at the bottom than it is at the top, and this annular space is divided into two chambers, dd, by means of partitions e 0, consisting of plates having their margins clamped between the flanges of the two halves of the casing at the bottom and top. I thus form two curved chambers exactly similar in shape and capacity,-
and each decreasing gradually in diameter 111 chambers of this tapering construction the rising water has a continual tendency to pack the sand or other granular filtering material, so that it will not be displaced upward by the water-flow, and the curved shapeofthc walls causes also an opposition to the rising of the said material.
The filter may be constructed of any materialearthen ware or meta-land may be cast in one piece. When cast in a single piece a suitablecore is made, conforming to the concentric shape of the vessel. The core-sand can be readily removed through the plug-holes for the plugs ff. The partition can also be cast with either of thesectious, in which case packing is not required.
, Each of the chambers (Z d has a screw-tap, f, at the top, forfilling in thefiltering material, and a similar tap,f, at the bottom, for removing the same. Atthe top the two chambers are connected by an outside arch-pipe, g, from the top of which a drawofi cock, It, projects laterally, and at the bottom each chamber has an inlet-pipe, t, the two inlet-pipes leading from a common loop-pipe, 7c, the opposite ends of which are connected bya cross-pipe, l, with p which is connected the main supply-pipe m. The ends of the loop-pipe k are also connected with exit-pipes at and n, which are used for taking off the foul water when the chambers are being cleaned out. The casing stands on legs 0 0, between which the lower pipe-connections are arranged. The-main supply-pipe and the cross-pipe Z are provided with cocks p on each side of the supply-pipe, between it and the loop-pipe 7c, and the exit-pipes n and n are provided with cocks g g.
In using the filter both the chambers d d are to be filled with sand or other granular filtering material about as high as thetaps ff, the cocks g g in the exit-pipes, in the supplypipe, and p12 in the cross-pipe are opened. The water willthen fiowfrom thesupply-pipein both ways through the cross-pipe l and loop-pipe 7c, and through the inlet-pipes z' i to both chambers d (1 simultaneously, and, rising through the filtering material, reaches the top of the chambers in a purified state and thence flows intothe arch-pipe, whence it may be drawn off as desired by means ot the draw-off cock h. Atthejnnction ofthe arch-pipe with the chambers suitable screens, 8 s, are provided to prevent the filtering material from rising into said pipe.
. When it is desired to wash the filtering material or the chambers, that of each chamber may be washed separately without interfering with the filtering operation of the other chamber. For instance, to wash out the chamber at the left, the cock 9 in the exit-pipe n is opened, and the cock 1) in cross-pipel at the left of the supply-pipe m is closed. Then supply-water will be cut off from the left-hand chamber, but will continue to flow to the right-hand chamber, and from it will pass through the arch-pipe g in a filtered and pure condition, and flow downward through the chamber on the left and oh through its pipe i, theleft-hand portion of theloop-pipe lo and exitpipe at, and may be left to flow until the filterin g material in said left-hand chamber becomes thoroughly clear of matter which has accumulated therein as a result of the filtering of water. The washing is performed with pure filtered water, which leaves no deposit behind it, and the filtering material is therefore thoroughly cleansed. It will be seen that the washing may be continued as long as desired, and during its continuance there will be no interruption of the operation of the right-hand chamber or of the supply of filtered water which may be obtained from the draW-ofi' cock g. The manner of washing out the right-hand chamber will be obvious.
To remove the filtering material, the taps at the bottom of the chambers are to be separately opened, and water may be caused to flow downward through each chamber separately, as when simply washing the material. The bottom taps being then closed and the top taps opened, fresh filtering material may be placed in the chambers.
The casing may be formed of either sheet or cast metal, or of earthenware, in two parts, as shown .in the drawings; or it may be cast of metal in one piece,including the partitions which separate the two chambers. In'the latter case the core-sand is readily removed through the apertures left for the screw-taps.
I am aware that doublechambered filters j arranged to permit water to fiow from one through the other for washing out are old and well-known, and I do not claim such a filter broadly.
What I claim is- 1. A double-chambered filter formed of the annular casinghaving the eccentric inner wall and the space within said casing divided into two chambers by the partitions e and e, whichform respectively common bottom and top plates for the two chambers, substantially as described.
2. A double-chambered filter composed of two curved chambers having their bottoms closed by a common bottom plate, and decreasing in diameter gradually from bottom to top, substantially as described.
3. The double'chambered filter herein described, consisting of the annular casing divided by the partitions e and e, to form two chambers, which are connected at top by the arch or pipe g, provided with a draw-01f cock, and having at their bottoms the inlet-pipes u, connecting with a loop-pipe, is, said loop-pipe havingits ends connected by a cross-pipe into which leads a supply-pipe, and also with exitpipes, said cross-pipe, supply-pipe, and exitpipes being provided with suitable cooks, for the purpose set forth.
4. A filter for filtering two semicircular sections, each section having a tapering inner chamber and induction and eduction openings for water and filtering material, said sections forming, when combined, an eccentric-shaped vessel with duplex inner tapering chambers, and connected as described.
5. An article of manutactureconsisting oftwo semicircular tapering chambers provided with two partitions and independent induction and educticn passages, the whole cast in one piece, as described.
In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
fluids, consisting of LYMAN SMITH.
