FILTER.

SPECIFICATION forming part of Letters Patent No. 373,257,

Application filed March 31. 1887.

12 all whom it may concern.- Be it known that we, JACOB WAEsrI, EMIL Fnnrz, JOHN SPELLMAN, and JOHN FREY, all

Texas, have invented a new and Improved and exact description.

The object of our invention is to provide a new and improved filter for purifying water intended for the use of cities, towns, &c.

The invention consists of various parts and details and combinations of the same, as will be'fully described hereinafter, and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate. corresponding parts in all thefigures.

Figure l is a plan viewof ourimprovement, showing a double filter. Fig. 2 is a longitudinal sectiouals elevation of the same on the line a: w of Fig. 1. Fig. 3 is a vertical cross-section of the basinon the line y y of Fig. 1. Fig. 4

her on the line z z of Fig. 1, and Fig. 5 is a vertical cross-section of the receiving-chamber on the line u u of Fig. 1.

In the construction of our improved filter we'inay employ only one filter; but we prefer to arrange two or more filters alongside of each other, each working independently of the others, but being alike in construction.

In the drawings we show two filters, A A, which are placed alongside each other and separated by a longitudinal partition-wall, B. The filters are built of suitable material and placed on agood foundation of masonry. Each filter A consists of a receptacle, 0, placed in an inclined position, and of an exit-basin, D, located horizontally at the foot of the receptacle C. The receptacle 0 is provided on its upper end with a receiving-chamber, E, in the provided with a valve, F, and connected by the branch pipe F with the main water -supthe llow of water into the branch pipes F. A drain-pipe, E, leads to the outside from the lower end of thereeeiving-chamberE through one of the side walls of the same. 'This' pipe E is provided at its outer end with a valve.

dated November 15,.13 7,

Serial No. 233.163. (No mndehl The lower wall, E, of the receiving chamber E is somewhat less in height than the chamher-walls, so that the water flows over the lower wall, E, into the settling-chamber H,

provided on its lower end with a drain-pipe, H, and with a lower end wall, H, over which the water flows into the gravel -chamber I,

which is filled with clean gravel entirely free In this chamber 1' are arranged, .6

from sand. at suitable intervals, theftransverse wedgeshaped ridges I, on which the impurities of the water accumulate, which impurities are drawn off, whenever desired, by the drain-pipe I, connected with each ridge and leading to ing and settling chambers E and H is to break the flow and the rush of the water, so that it 90 passes quietly intothe gravel-chamber I, in which it passes through the gravel, which deprives it of its impurities, which settle on the bottom, principally against the ridges I. The

impurities settling alongside the ridges I can be drawn ofi" .whenever desired through the drain-pipes I. The perforated plate Ip'ermits the passage through it of' the water into the basin D, in which the water, should it possess a disagreeable odor, is deprived of the same in passing through the charcoal-box'J, and it finally enters the main outlet-pipe K in a pure and healthy state.

The several chambersof each filter can easily.

be cleaned by closing the valve F, thusshutting 9 5 oh the supply of water, and then the several .drain-pipes E, H, I", and D are opened, so

that the waterin the several chambers is drawn off. The chambers E H and the basin D are cleaned by the use of a hose, L, connected with too a plug, N, on the branch pipe F.

In order toclean the gravel-ehamber I, it is neeeseery that part of the grm el in the upper part of the chamber should be removed,- and the remaining part is washed by the hose L, as illustrated in Fig. 1. Y The impuritieson the 5 bottom settle against the first ridge and pass amt thmcgtrthe first drain-pipe, I, connected with the said ridge. The gravel is then repiaeed, and the followingsections of the chemher I are washed in the same manner, if nect0 essary. The arrangement shownin the drawing permits ofr'ieaning one of the filters 'while weather is working.

Having'thus fully described our invention,

we claimasnew' and desii'exo secure by Letters 5 Patent- The filter cansisting of the receptacle having the receiving, settling, and filtering chamhers, in the bottor'nof which filtering chamber are formed transverse wedge shaped ridges,

and at the bottoms of the receiving, settling, 20

and filtering chambers and of the basin are arranged outlet-pipes, which receiving, set-. tling, and filtering chambers are separated from one another by walls or pfirtitions pfsuccessively varying or lesser'heights, and which 25 basin is arranged lower than the filteri rig-chamber, together with a branched supply-pipe connecting with valved perforated pipes 'arranged in the receiving-chamber, substantially as end'for the purpose specified.
