I, WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for AN IMPROVED STEAM-HEATING APPARATUS FOR WARMING
HOUSES AND FOR SIMILAR PURPOSES ALSO APPLICABLE FOR USE. AS A WATER-
HEATER to be as follows:-.
33
This invention relates to steam heating apparatus and comprises the improve-
ments hereinafter described.
In carrying the said invention into practice I provide an ordinary cylinder
heating stove within which is located a coil of pipe of comparatively large
diameter. This coil occupies the place usually occupied by fire bricks; but fire-
bricks may also be employed if their use be deemed best but I regard it as
preferable to employ a cast-iron cylinder in the place of fire-bricks, so as to expose
the coil more directly to the incandescent fuel, and yet protect it somewhat from
the fire; and I also deem it best to place a sheet-iron cylinder around the outside
of the coil.
A smaller coil is arranged within the lower part of the large coil. The small
coil is of such diameter as not entirely to fill that part of the large coil in which it
is arranged, and is open at both ends. The upper end of the large coil enters a
horizontal pipe located outside of the stove, and the end is connected with a check
valve. The said valve may be made in any well-known or suitable way adapting
it to prevent the steam from forcing the hot water in the large coil back through
the said valve, and permitting it to open automatically when the steam pressure
is comparatively low or weak or at its minimum.

page_text: An open water-tank is provided from which a pipe passes into the upper part of
the check valve.
A valve or cock is located in the said pipe between the check valve and the tank.
A drip and equalizing pressure pipe, enters the horizontal pipe and the upper
part of the check valve but extends downward a little way below the end of the
water-pipe, a shut-off or cock is arranged in the drip pipe.
The apparatus is provided with a condenser.
Pipes pass from the horizontal pipe to the radiator coils located in the different
rooms to be beated.
A second drip-pipe passes from the condenser into the upper or open end of the
water-tank.
A safety-valve is placed upon the apparatus and a tap is placed at the lower
end of the check-valve. A drip-pipe passes down from the coil in each room,
respectively into the condenser.
The operation is as follows that is to say, I fill, or nearly fill, the tank with
water and set the valve or cock in the water-pipe so as to permit the required
amount of water to pass through the water-pipe and check valve into the coils.
When the pressure below the check-valve exceeds that above it, the said valve will
thereby be automatically closed, and so temporarily shut off the supply of water to
the said coils. However, when the pressure above the valve exceeds that below it,
that valve will thereby be automatically opened, and a due amount of water again
supplied to the coils. The steam pressure, as will be perceived, is liable to
variation, and this variation I utilize, through the instrumentality of the means
described for feeding the water automatically into the heater, as occasion requires.
The first drip and pressure equalizing pipe aids very materially in the accom-
plishment of this result by furnishing steam-pressure which enters the valve-shell
at a point above the check-valve and equalizes the pressure so as to permit that
valve to open and close at the proper time without noise.
It is to be understood that the fire should be so regulated, and the water tank at
such elevation, that the water will be generated into steam before leaving the large
coil and that if any water should be carried to the horizontal pipe it will be
drained therefrom into the first drip pipe and thence into the check-valve and coils
when the pressure on top of the check-valve exceeds the pressure below it. Any
pressure exerted above the said valve through the first pipe may be prevented by
closing a cock. The steam thus generated will pass to the radiator coils for
heating the rooms, and the drip or condensation in those coils may be allowed to
pass down through pipes into the coudenser and thence into the water-tank.
The safety valve prevents danger from too great steam-pressure.
The coils may be drained or emptied by opening the drip tap. The open small
coil holds a portion of the water away from as direct heating by the fuel as the
water in the large coil is exposed to, and thus modifies, to some extent, the
temperature of the water and tends to prevent too sudden or rapid evaporation.
The water in the small coil, however, eventually passes into the large coil and is
converted into steam, and the smaller coil is again filled, as well as the large
coil pipe.
This apparatus may also be used as a water-heater by permitting the water to
enter the coils faster than it can be generated into steam, and the water so beated
may be conducted away from the heater for use.

page_text: I is a drip and
fanzing pressure pipe,
of the valve E, but extending downward a little way below the end of the
pipe G.
A shut off cock J is arranged in the pipe I.
LL are pipes passing from the pipe D to the radiator coils located in the different
rooms, respectively.
K is a condenser from which a drip-pipe M passes into the upper or open end
of the tank F.
N is a safety-valve, and O is a tap placed at the lower end of the valve E.
A drip-pipe, P passes down from the coil in each room, respectively into the
condenser.
The operation is as follows that is to say:-I fill, or nearly fill, the tank F with
water and set the valve or cock H so as to permit the required amount of water
to pass through the pipe G and valve E into the coils B and C. When the pressure
below the valve E exceeds that above it, the said valve will thereby be auto-
matically closed, and so temporarily shut off the supply of water to the said coils.
However, when the pressure above the valve E exceeds that below it the said valve
will thereby be automatically opened, and a due amount of water again supplied
to the coils. The steam-pressure, as will be perceived, is liable to variation, and
this variation I utilize, through the instrumentality of the means described for
feeding the water automatically into the heater, as occasion requires.
The drip and pressure-equalizing pipe I aids very materially in the accom-
plishment of this result, by furnishing steam-pressure which enters the valve-shell
at a point above the valve E, and equalizes the pressure so as to permit the said
valve to open and close at the proper time without noise.
It is to be understood that the fire should be so regulated, and the tank Fat
such elevation that the water will be generated into steam before leaving the coiled
portion of the pipe B, and that if any water should be carried to the pipe D it will
be drained therefrom into the pipe I, and thence into the valve E and coils B and C
when the pressure on top of the valve E exceeds the pressure below it; any pressure
exerted above the said valve through the pipe I may be prevented by closing the
cock J.
The steam thus generated will pass to the radiator-coils for heating the rooms,
and the drip or condensation in those coils may be allowed to pass down through
the pipes P P into the condenser K, and thence into the tank F. The valve N
prevents danger from too great steam-pressure.
The coils B and C may be drained or emptied by opening the drip tap O. The
open small coil C holds a portion of the water away from as direct heating by the
fuel as the water in coil B is exposed to, and thus modifies, to some extent,
the temperature of the water in the pipe B, and tends to prevent too sudden or
rapid evaporation. The water in the pipe C, however, eventually passes into the
pipe B, and becomes steam, and the smaller pipe is again filled, as well as the
pipe B.
This apparatus may also be used as a water-heater by permitting the water to
enter the coils faster than it can be generated into steam, and the water so heated
may be conducted away from the heater for use.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign Correspondent, I declare that what I claim is
First. The combination, substantially as described, in a steam-heating apparatus,

distributing pipes and heat-radiators; the water-supply pipe G; the valve or
cock H, located in the pipe G; and the automatic valve E, also located in the
pipe G and communicating with the pipe B, and arranged between the latter pipe
and the valve or cock H, for the purposes specified.
