N 0. 826,654. Specification of Letters Patent.

Application filed April 18, 1906. Serial No. 312,312

Patented July 24, 1906-.

To all whont it may concern.-

Be it known that I, FRANKLIN E. FIRTH, a citizen of the United States, residing at To ledo, in the county of Lucas and State of Ohio, have invented a new and useful Improvement in Self-Cooling Filter Systems, of which the following is a specification.

y invention relates to a self-cooling filter system for water, and has for its object to provide an automatic system of the kind that is simple, inexpensive, and convenient and in which the water after being filtered is cooled by earth radiation. I accomplish these objects by the construction, combination, and automatic operation of parts hereinafter described, and illustrated in the drawings, in which- Figure 1 is a vertical longitudinal section of the filter-tank and cooling-well, showing the supply and siphon pipes of the coolertank broken through. Fig. 2 is a side elevation of the same, also showing the supply and siphon pipes of the cooling-tank broken through and Fig. 3 is a top plan view of the same.

In the drawings, 1 represents the filtertank, which is provided with an integral flared base-flange 2, by which the tank is mounted on a suitable support 3. The tank 1 is cylindrical above the base-flange 2 and is preferably constructed of sheet metal. The tank is provided with a bottom closure 4 and with a removable cap-closure 5 at the top. Within the tank 1, resting on the bottom 4 and closely fitting the cylindrical wall of the tank, is provided the annular packing 6, upon which rests the bottom rim 7 of the filter 8.

The filter 8 comprises the cylinder 9, having the perforated conical bottom 10 and the interior top handles 11, by which the cylin-- der is lowered into and lifted from the tank 1, the diameter of the cylinder 9 adapting it to telescopically enter within the tank and the filter material suitably packed within and filling the cylinder 9 and comprising the bot tom layer of coarse gravel 12, a body of charcoal superimposed on the gravel, and a top layer of sand. Above and resting on the top of the cylinder 9 is provided a perforated diaphragm 13.

In the top portion of the tank 1 is supported by its concentric flange-rim 14, which enages the rim 15 of the tank 1, and by the I egs 16, which rest on the diaphragm 13, the supply-tank 17, which is provided with the bottom 18 and with the perforated sponge= pocket 19 at one side. The top, which is open, is adapted to be closed by the sure 5, which rests on the flange-rim 1 1' and is provided with a flange 20, which fits into the top portion of the supply-tank.

Near the bottom of the sponge-pocket 19 there is provided an orifice in the wall of the supply-tank, in which is fitted a flanged nipple 21, which is both interiorly and exteri- 18 provided in the wall of the tank 1 an enlarged orifice 22, through which extends one end portion of a pipe 23, which is eXteriorly threaded to permit the nipple 21 after being inserted through the orifice in the supplytank to be run on the threaded portion of the discharge-pipe. The outer end of the nipple is conically reduced to fit into the conicallyreduced inner end portion of the bore of a coupling-sleeve 24, which is mounted on the 'scharge-pipe and has an inner end portion 25, which is adapted to enter the orifice 22 hich is interiorly threaded to run on the'eXterior threads of the nipple 21, and an outer squared head-flange 26, adapted to be engaged by a wrench, by which the parts are drawn together to form a water-tight connection of the discharge-pipe to both the sup ply-tank and the tank 1.

Through suitable opposite orifices'near the tops of the tanks 1 and 17 there is detachably coupled in a similar manner as described for the pipe 23 a supply-pipe 27, which is connected to a main supply under head-pressure, and in the coupling 28 is provided a valve which is controlled by a float 29, which closes the valve when the water in the supply-tank reaches a predetermined level and opens it when it falls below, whereby the supply is made automatic and according to quantity used.

The pipe 23 extends from its connection with the supply-tank downward to the base flange 2, through a suitable orifice in which it extends to and through the center of the bottom 4 of the tank 1 into the chamber 30, formed between the bottom 4 and the perforated conical bottom 10 of the filter-cylinder 9. The tanks 1 and 17 being thus connected, the pressure of water in the supply-tank gradually forces the water upward through thefilter 8 into the middle chamber31 between the filter and the supply-tank.

Above and near the diaphra m 13 is tapped into the chamber 31 of the tank 1 a dischargecap-010+ orly threaded, and opposite the nipple there ICC IIO

The cooling-cylinder is provided with a pipe 36, which extends from near the bottomof the cylinder 33 upward through its closed top and through the well to a point that is below the level of the chamber 31, where it is of the supply-pipe.

under the pressure of the water in the supplybent horizontal and provided with a suitable faucet closure valve 37. There is also tapped into'the tank 1 opposite the chamber 31 a faucet-valve 38.

Above the established water-level of the supply-tank 17 through suitable opposite orifices in the tanks 1 and 17 there is coupled by a detachable coupling 39, similar to the coup- .ling for the pipe 23, a waste-pipe 40, which extends downward along the outer wall of the tank 1 and is connected in any suitable manner with a drain-pipe.

Below the bottom 4 of the tank 1 there is ,provided a flushing-pipe 41, which is coupled the waste-pipe 40,,

to both the pipe 23 and and the pipe 41 is provided with a closurevalve 42. The supply-pipe 27 is also provided with a closure-valve 43. Thus constructed and connected and the flushingvalve being closed when the closure-valve 43 is opened the water will flow into the supplytank 17 and thence through the spongepocket and the pipe 23 into the chamber 30 until the resistance of the filter causes the chamber 30 and the pipe 23 to be first filled and then the sup ly-tank to be filled to the level where the oat will shut off the valve Gradually the water tank will be forced up through the filter 8 and the diaphragm 13 until it reaches'the outletipe 32, which will drain the filtered water from the chamber 31 until the cooling-cylinder 33, the pipe 32, and the pipe 36 are all filled, the fioat valve being automatically opened from time to time to supply the necessaryi quantity of water for such filling of the system, after which the water will rise in chamber 31 through gradual filtration until the level of the filtered water around the su ply-tank reaches the level of the water in tfie supply-tank, which closes the float-valve of the supply-pipe.

When the system is once filled and the temperature of the water in the cooling-tank has been reduced by radiation to the normal earth temperature at the bottom of the well, (which is about 45 Fahrenheit) water under the pressure of the greater height of the column of filtered water in pipe 32 and in the chamber 31 of the tank 1 may be drawn off through the faucet 3 from the pipe 36.

rupt the use of the system,

After a quantity equal to the cubic capacity of the pipe 36 has been drawn therefrom, which may be returned to the supply-tank, the water will be of the temperature of the water in the cooling-cylinder.

It is obvious that my system is automatic and continuous, and that after being once filled a quantity of water willbe automatically supplied thereto equal to that withdrawn. In order that filtered water for culinary purposes may be drawn therefrom withoutusing the cooled water in the cooler-tank, I have provided the faucet 38, whereby filtered water may be drawn from the chamber 31 before it has passed through the cooler,

By closing the valve of the supply-pipe and opening the flushing-valve 42, the water in the chambers 30 and 31 is discharged through the flushing-pipe 41 into the waste-pipe 40, whereby any sediment in the bottom of chamber 30 is flushed out. i

In the event of a leak in the float-valve of the supply-pipe which would cause the water in the suppl tank to rise above the level at which the fioat closes the valve such excess water therein will pass out through the waste-pipe 40.

In order that the repacking of the filtercylinder 9 with fresh material may not intera duplicate of cylinder 9 is preferably rovided, which may be kept suitably packed and ready for substitution, which requires only the closing ofthe valve 43 of the supply-pipe, the detachment of the couplings of the waste, supply, and discharge pipes of the supply-tank, and the removal of the supply-tank and diaphragm, after which the filter-cylinder 9 may be lifted from the tank 1 and the duplicate insertedin its place. The diaphragm and supply-tank being again placed in position and coupled to the waste, supply, and discharge pipes and the valve 43 being reopened, the system will be ready again for withdrawing water from the cooling-tank as soon as the chambers 30 and 31 are refilled by the automatic action of the system. The removed cylinder 9 may be then repacked in readiness for use when its duplicate requires repacking.

It will thus be seen that I have provided a convenient and inexpensive system whereby filtered water cooled to potable temperature by earth radiation is continuously and automatically supplied as needed for use.

A sponge is preferably packed in the sponge-pocket of the supply-tank to prevent the heavier sediment or impurities of the water from being deposited in the chamber below the filter.
