FILTER.

SPECIFICATION forming* part of Letters Patent No. 789,942, dated May 16, 1905.

Application filed February 18, 1905. Serial No. 246,265.

To all whom, it may concern:

Be it known that I, JOHN E. SKELTON, a citi- Zen of the United States, residing' at Shelbyville, inthe county of Shelby and State of Kentucky, have invented a new and useful Filter, of which the following is a specification.

This invention relates to filters, and it has special reference to that class of filters which are connected with rain-water conduits for the purpose of filtering the rain-water prior to its passage to the cistern.

The invention has for its object to simplify and improve the construction and operation of this class of devices; and with these and other ends in view, which will readily appear as the nature of the invention is 'better understood, the same consists in the improved construction and novel 4arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claim.

ln the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that the right is reserved to any changes, alterations, and modifications to which recourse may be had within the scope of the invention and without departing from the spirit or sacrificing the efiiciency of the same.

Inv said drawings, Figure 1 is a vertical sectional view showing a filter constructed in accordance with the principles of the invention. Fig. 2 is a horizontal sectional view taken on the line 2 2 in Fig. 1. detail view illustrating a modification.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

The improved filter has been shown as comprising a casing 1 of cylindrical shape and provided with a detachable cover 2. Said cover has an inlet 3, adapted to be connected with a water spout or conduit, and the bottom of the casing has an outlet 4, adapted to be connected with the outlet leading to the cistern.

The body of the casing has a transverse par- Fig. 3 is a sectional,

tition 5, whereby it is divided into two separate chambers or compartments 6 and 7. The compartment 6 is provided at the bottom thereof with a waste-pipe 8. The outlet 4 is connected with the bottom of the compartment 7. 4

The casing is provided near its upper end with a diaphragm composed of two separate members 9 and 10, which are fitted, respectively, to the compartments 6 and 7 and which are removably supported upon brackets 11 near the upper ends of the walls of said compartments. The compartment 6 contains an additional diaphragm 11, detachably supported upon brackets 12. The diaphragme 9, 10, and 1l' are constructed of reticulated or foraminous material, such .as perforated sheet metal, wire-gauze, and the like. The diaphragm member 10 at the upper end of the compartment 7 is connected by a bent 'or L- shaped pipe 13 with the lower end of the compartment 6 beneath a perforated partition 14, which is supported near the lower end of said com partrn en t.

A pipe 15 extends through the perforated partition 14 and the diaphragms 11 and 9, and said pipe may, if desired, be rigidly connected with the partition 14, so that the latter may be lifted out thereby.

The partition 5 is provided above the diaphragm composed of the members 9 10 with a transverse opening, in 4which is detaehably seated a box or tank 16, one end of which is out away to form an overflow within the compartment 6. Pivotally supported in said tank is a lever 17, provided at the end which eX- tends within the compartment 7 with a float 18 and connected at its other end, which extends within the compartment 6, with a stem 19, carrying a valve 20, having a seat 2l at the inner end of the waste-pipe 8.

The side of the vcasing 1 is provided near its upper end with an opening 22, for which a closure 23 is provided. A strainer 24 extends from the lower edge of the opening 22 to the upper edge of the partition 5, and said strainer, as will be observed, is disposed beneath the inlet 3, which latter is located at one side of the axis of the casing. rlhe compartment 6 between the partitions 14 and 11 is IOO packed with charcoal or other suitable filtering material. The compartment 7 between the bottom of the casing and the perforated diaphragm member 10 is likewise packed with filtering material of any suitable description. The pipe 13, extending through the compart- .ment 7, may be removable, if desired. The

tank 16 is provided at or near the overfiow end of said tank and within the compartment 6 with a drain-opening 25.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood. y

The water entering at the inlet 3 will pass through t-he strainer 24, where leaves and other trash will be separated, to be subsequently removed through the opening 22. A portion of the water percolating through the strainer 24 will pass into the tank 16, thus raising the float 18, depressing the valve-stem 19, and seating the valve 20, thus closing the wasteoutlet 8. As the water rises to the level of the eut-away end of the tank 16 it overflows land together with a portion of' the water passing through the strainer 24 percolates through the diaphragm member 9, the partitionl 1, and the bottom member 14, as well as through the filtering material contained between said bottom member and the partition 11. Finding no outlet through the waste-pipe 8, on account of the valve 2O being closed, the water will rise through the pipe 13, overow at the upper end of the latter, and pass through the diaphragm member 10 and percolate through the filtering material contained between said member and the bottom of the compartment 7, finally escaping through the exit 4. When the -supply of water through the inlet 3 ceases, the contents of the tank 16 will escape through the drain-opening 25, causing the lioat 18 to descend, thereby unseating the valve 2O and permitting the water contained in the compartments 6 and 7 and .in the pipe 13 to escape through the waste-pipe 8, thus preventing water from becoming stagnant in the filter-casing in hot weather and preventing it from freezing during the cold season.

In Fig ofthe drawings has been illustrated a slight modification under which the strainer 24 is dispensed with, the inlet-pipe (here designated 26) being widened to form a funnel 27 in the wide part of' which a strainer 28 is disposed. The water conduit 29 has been shown as'provided with a widened or inverted-funnel shaped portion 30, suitably connected with the funnel 27. This and other modilications of a like nature may be resorted to within the scope of the invention.

Having thus described the invention, what is claimed is- A filter-casing having a transverse partition, filtering-compartments at each side of' said partition, means for conveying water from beneath the filtering device in one compartment through the filtering material in the other or refiltering-compartment to an outlet at the bottom of said refiltering compartment, a waste-pipe at the bottom of' the space beneath the primary filter, a pipe extending through the primary filtering device, a tank supported detachably in the partition above the filtering devices in the two compartments, said tank having a cut-away portion above the primary filter and a small drain-opening, an inlet above said tank, a lever fulcrumed in the latter and having a lioat at the end extending above the refltering-compartment, a valvestem connected with the opposite end of' said lever and extending through the guide-tube in the primary filter, and a valve at the lower end of said stem seated in the inner end of the waste-pipe.

In testimony that I claim the foregoing as my own I have hereto aiiixed my signature in .the presence of two witnesses.
