FILTER.

SPECIFICATION forming part of Letters Patent No. 451,060, dated April 28, 1891.

Application filed June 23, 1890. Serial No. 356,407. (No model.)

To (on whom it may concern.-

Beit known that I, JOHN F. LE BEAU, a citizen of the United States, residing at Toledo, Ohio, have invented certain new and useful Improvements in Filters, of which the following is a specification.

My invention relates to that class of filters in which the water percolates both upward and downward; and its object is to provide a filter which shall be cheap, simple, durable, and effective, and more particularly to utilize the legs or standards which support the body of the filter as filtering-conduits. I attain these objects by means of the mechanism hereinafter described, and shown in the accompanying drawings, made part hereof, in which- Figure l is a side elevation of my filter; Fig. 2, a central vertical section on line y 1 Fig. 3; Fig. 3, a sectional plan view on line 00 m, Fig. l; and Fig. 4, a sectional plan view on line .2, Fig. 1.

Like letters indicate like parts in all the views.

A is the body of the filter, which for convenience I prefer to make cylindrical in form. The body of the cylinder is divided into two compartn1entsone e for the impure water, the other f for the filtered water-the partition between the two compartments being marked B. The body of the filter A is provided with the usual cap or cover O, and is supported upon four hollow legs or standards (I, (1, (Z and d These legs or standards are made, preferably, of heavy sheet metal, and terminate at bottom in and are rigidly secured to base-plate g. Each of the legs is is filled with filtering material-such as charcoal, gravel, and the 1ike-resting on perforated plates 0, fixed near the bottom of each of the hollow standards. Leg or standard at is provided at its top with a perforated cap, through which water enters from chamber 6, and at bottom with a sponge-box h, (see Fig. 2,) provided with a screw-cap h, by means of which the sponge may be readily withdrawn, cleansed, and inserted in place. Around this sponge-box is a sediment-chamber h from which, through horizontal pipe twater passes to leg or standard d, thence upward through this leg or standard until it reaches horizontal pipe 01, thence over through pipe 1" to leg (1 thence downward through leg or standard (1 into sediment-chamber 7c, thence into leg or standard d through horizontal pipe t thence upward through-leg or standard (P, and out through perforated plate at top of the last-mentioned leg or standard into the pure-water chamber f, from whence it may be drawn through cock or spigot Z. Thus it willbe seen the course of the water from the impurewater chamber 6 into the pure-water chamberf is as follows: downward from chamber e through standard d, through sponge-box h, sediment-chamber 7%, horizontal pipe 2', up through standard d, over through horizontal pipe 1', downward through standard d int-o sediment-chamber 7c, over through horizontal pipe 1 and thence up and out into the purewater chamber f through standard (1 the four legs and their connecting-pipes thus forming a continuous conduit from chamber eto chamber f. Standards d and d are also provided with sediment-chambers at bottom, (not shown in the drawings,) the sediment-chamber in each of the standards being directly beneath perforated plate 0. Each of the four legs of the standards is provided at bottom with screw-caps, by means of which the sedimentchambers are readily emptied and cleansed. Standards (1' and d are provided with screwcaps at their top. By removing the last-mentioned screw-caps and the perforated plates above referred to and inverting the filter the filtering material may be readily removed, and through the same openings the filter may be conveniently repacked. The water in its course above described enters the various sediment-chambers by percolation Without disturbing the sediment, and'the sediment which accumulates in the sediment-chambers is not disturbed by pouring water into the impure-water chamber or withdrawing water through spigot Z.

Around the body of the filter I provide an outer jacket a, between which and the body of the filter is an annular space a, closed at bottom. The air-jacket thus formed serves as a non-conductor of heat, andthe water within the filter is thereby kept cool.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

A filter having the body thereof divided into two chambers and supported upon four covering the inlet and outlet of said filteringhollow legs connected and adapted to form a conduit, and screw-caps closing the upper IO continuous filtering-conduit leading; from one ends of legs d and (5 substantially as shown to the other of said chambers, each of said and described, for the purpose specified.
