Improvements in Apparatus for Purifying and Cooling Water.
I, GEORGE SIMPSON, of Chestnut Hill, Philadelphia, Pennsylvania, United States of
America, Inventor do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My invention relates to water purifiers and coolers, and consists first, of a tank
provided with a heating device having a water supply pipe and a discharge pipe,
leading into the tank, and a gas or other burner, and means for automatically con-
trolling the supply of the water and of gas or other heating medium.
It further consists in the combination of parts herein set forth.
In the accompanying drawing :-
Figure 1 represents a vertical section of a water purifier and cooler embodying my
invention.
Figure 2 represents a vertical section of a portion on the line a, x, Figure 1, on an
enlarged scale.
A designates a tank or vessel, and B designates a pipe leading into said tank, said
pipe being connected with or continuous of a coil C, which constitutes a heater for
water admitted thereinto by the pipe D, the latter being in communication with a
source or supply of water, and provided with a valve or cock E for regulating the
flow of the same into said pipe, and consequently to the heater C.
Below the coil or heater C, is a gas burner F, which is connected with the gas
conveying pipe G, the latter being provided with a cock or valve H, whereby the
supply of gas or other vapor, fuel or burning medium to the burner, may be controlled,
and the flame or heat accordingly regulated.
The keys or plugs of the valves or cocks E, H, are connected with a rotatable
stem J, to which is attached the arm K of a float . The pipes D and G may be
secured to the tank A in any suitable manner, or sustained in a position adjacent to,
or near said tank, so that the float is within the tank A, it being evident that the
heater C and burner F are properly sustained on the tank or adjacent thereto.
Within the tank A are partitions M, N, which form a well and cold air space Q,
the same being in communication as at P, with an ice or cooling chamber R, which is
located in the upper end of the storage vessel S, which vessel is in communication
with the tank A, at the bottom thereof.
The vessel S and well Q are provided with cocks or faucets, as at T, U, for evident
purposes.
The operation is as follows:-
The tank A and vessel S are primarily supplied with water the cock or valve H
being adjusted so that a limited quantity of gas is supplied to the burner F, for
maintaining a small flame thereat.
When the water is taken from the vessel S, that in the tank A lowers, and the float falls,
whereby the cock is opened, thus admitting water into the pipe D, and consequently
into the coil or heater C.
The cock H is also opened, whereby a full volume of gas is admitted to the burner F,
so that the water in the coil C is heated or boiled.
The hot water leaves the coil and is directed by the pipe B into the tank, and from
there into the vessel S, and reaches the chamber R, so as to be cooled by contact with
the same.
When the tank A is full, the float rises, and the valve or cock of the water pipe is
rotated, so as to cut off the water. The valve or cock of the gas pipe is also rotated
so that the full head of gas is cut off, leaving however, a small quantity of the gas
burning, so that a flame is constantly maintained, ready to be enlarged for boiling a

page_text: fresh supply of water admitted into the coil or heater, when the float again falls, the
latter being raised by the withdrawal of water from the vessel S, as previously
stated.
The coil or heater is surrounded by a casing V of non-conducting material, both as
a guard and preventative of loss of heat.
A diaphragm W of filtering material is located at the bottom or inlet end of the
vessel $ for evident purposes, but if desired, the water may be filtered prior to its
entrance into the pipe.
The cold air space or well Q serves to cool the water in the tank A, as well as in
the vessel S, and said space or well receives the melted ice, leaving the chamber R
through the outlet or opening P, and is cooled by the same.
It is evident that water may be readily prepared and purified for drinking, cooking,
and other purposes, by the treatment to which it is subjected, the operations being
conveniently and reliably performed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
--
First. In a water purifier, a receiving tank and a communicating storage vessel, in
combination with a heater, a gas or other burner, cocks or valves connected with said
heater and burner, and a float for controlling said cocks or valves, the heater having
a pipe leading from a source of supply, and one leading to said tank, substantially as
described.
Second. In a water purifier, a heater for the water, and an automatically operated
valve for supplying said heator with gas or other suitable medium, in combination
with a receiving tank and a cooling device, substantially as described.
Third. A water purifier and cooler, consisting of a tank having two partitions,
forming a water-receiving chamber a cold well, and a purified water reservoir or
chamber, the latter having a filtering bottom, a heater outside of said tank, a pipe
leading from a source of supply to the heater, and a pipe leading from the heater to
the tank, a float in the water, receiving chamber connected with a valve in the water
supply pipe, and an ico chamber communicating with the cold well, said parts being
combined substantially as described.
Fourth. A water purifier consisting of a tank with partitions, forming a water-
receiving chamber, and a storage or purified water chamber, the latter having a
filtering bottom through which the water upwardly passes into said chamber, a heater
outside of said tank, a pipe leading from a source of water supply to the heater, and a
pipe leading from the lieater to the tank, a float in the water receiving chamber
connected with a valve in the water supply pipe, and an ice chamber communicating
with the cold well, said parts being combined substantially as described.
Fifth. A water purifier consisting of a tank having the partitions M, N, forming a
water-receiving chamber, and a storage chamber with an intervening cold well, a
heater outside of said tank, a supply pipe leading into said heater, and a gas pipe with
burner valves in said pipes, an oscillating bar secured to said valves, and journaled in
the sides of the tank, a float with an arm attached to said bar, and a pipe leading
from said heater into said water-receiving chamber, said parts being combined.
substantially as described.
