IMPROVEMENTS IN SUPPLYING HOT WATER IN HOUSES AND OTHER BUILDINGS,
AND IN MEANS OR APPARATUS THEREFOR."
This Invention relates to improvements in supplying hot water in houses and
other buildings having a constant water service, and it has for its object to avoid
the use of the ordinary cold water cistern at the top of the house and the long
circulating pipes and large boiler capacity at present required with the ordinary
system. This result I obtain by taking advantage of the pressure existing in the
cold water mains to force the hot water to the upper part of the house or else-
where where required in the following manner: In any convenient position in
proximity to the boiler I place a closed tank or cylinder of suitable capacity, and
connect such tank or cylinder with the boiler or heating coil in the fire-place by
short circulating pipes. Cold water is supplied to such tank or cylinder by a pipe
from the main, led down through the top of the tank or cylinder to within a short
distance of the bottom, this cold water pipe terminating just below the level of the
return circulating pipe. The heated water is taken where required by a pipe from
the top of the tank, and on drawing off hot water at the top cold water enters
at the bottom and passes directly into the circulating pipes and boiler. The whole
of the hot water can be drawn off from the tank, if required, the cold water entering
at the bottom to replace it.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said William Dakin Waterhouse in the Great Seal Patent Office on the 21st
July 1876.

page_text: MEANS OR APPARATUS THEREFOR." A communication to me from abroad by James
Archer, of Denver, in the State of Colorado, United States of America.
This Invention relates to supplying hot water in houses and other buildings
having a high pressure water service, and it has for its object to avoid the use of
the ordinary cold water cistern at the top of the house and the long circulating
pipes and large boiler capacity, and also effect a great reduction in the expense of
labor at present required with the ordinary system. This result I obtain by taking
advantage of the high pressure existing in the cold water service pipe, to force the
hot water to the upper part of the house or elsewhere in the following manner:
In any convenient position, as near to the fire-place as possible, I provide a closed
cylinder or cistern of suflicient capacity to hold the quantity of hot water required
at one time, and I connect this cylinder with a boiler or heating coil in the
fire-place by circulating pipes. The water service is supplied direct to the cylinder
at the lower part by a pipe, which enters by preference at the top, and passing
down through the cylinder terminates at a short distance from the bottom and
just below the level of the return circulating pipe, in order that the inflowing cold
water shall mingle as little as possible with the heated water in the upper part
of the cylinder. The high pressure cold water entering at the lower part of the
cylinder, as above mentioned, exerts its pressure directly upon the heated water
in the upper part in order to force it to the height required. The cold water passes
from the bottom of the cylinder to the boiler or coil, and thence back by the return
circulating pipe to the cylinder, whence it is conveyed where required by a pipe
connected to the top of the cylinder.
In order that the Invention may be more readily understood I have illustrated
it in the accompanying Drawing, in which A represents (in vertical section) the
hot water cylinder or reservoir placed in, say, the basement of the house, and as
near as possible to a boiler or heating coil D of any suitable kind, with which it is
connected by circulating pipes B and C. The pipe B connects the bottom of
cylinder A with the lower part of the boiler or coil, and the return pipe C is led
from the top of the boiler or coil into the cylinder A at a short distance above the
bottom; E is the cold water supply pipe. It is preferably led through the top of
the cylinder A, and down through said cylinder as shown to a point below the
level at which the return pipe C is connected to the cylinder; F is the pipe con-
nected to the top of the cylinder by which the hot water is conveyed where
required.
Having described the nature of the said Invention, and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is providing a supply of hot water in
houses having a high pressure service of cold water by leading the cold water
supply pipe directly into the lower part of a closed cylinder placed near to and
connected with a boiler or coil by circulating pipes, the hot water being taken from
the upper part of said cylinder and conveyed where required, all substantially as
herein shown and described, thus dispensing with the cold water cistern at the top
of the house, the long circulating pipes generally used, and considerably reducing
expense of labor.
In witness whereof, I, the said William Dakin Waterhouse, have hereunto set
my hand and seal, this Seventeenth day of July, in the year of our Lord
One thousand eight hundred and seventy-six
