Improvements relating to Steam Heating Apparatus.
1, HENRY MAXSON WILSON, of Prudential Buildings, Mosley Street, Newcastle-
on-Tyne, in the County of Northumberland, Engineer (being a communication
from J. Langridge, Engineer, of Yokohama, Japan), do hereby declare the nature
of this invention to be as follows:-
:-
This invention relates to improvements in steam heating apparatus, my object
being to construct and arrange a convenient and economical heater, having simple
appliances for automatically effecting the removal of the water formed by the
condensation of steam.
In carrying my invention into effect in the construction of a steam heater for
the purpose of heating the atmosphere within a building or for other purposes,
I connect to the radiating pipes or like parts, a condensed steam chamber or vessel.
This chamber or vessel is preferably of a circular configuration and contains a
hollow Hoat, constructed from thin copper sheeting or other metal and having at
its lower end a valve, for regulating the discharge of the water or condensed
steam. At the upper end of the chamber I provide a guard plate having a screw
plug inserted at its centre for the purpose of regulating the lift of the valve, a hole
being formed through the plug for the purpose of receiving the guide stem attached
to the upper end of the float. The valve attached to the lower end of the float is
contained within a chamber into which the water or condensed steam is admitted
by perforations through its surface.
On the admission of steam to the chamber or vessel it becomes gradually
condensed through loss of temperature. The accumulating water causes the float
to rise and thus to lift the valve from the mouth of the discharge pipe, and so
permit of the escape of the water from the chamber. I prevent the entire closing
of the valve on the descent of the float by means of the regulating screw plug in
the guard plate at the upper end of the chamber, or by forming a small hole or
passage through or past the valve sufficient to maintain the required movement or
circulation of steam through the heater.
I sometimes take advantage of the expansion and contraction of the float under
the influence of the steam and water, to allow the valve to close or almost close the
aperture when the chamber is at a sufficiently high temperature, but to be lifted on
cooling to permit of discharge from the chamber.
1 sometimes employ my condensed water chamber with valve and fittings as an
independent heater, without the use of radiators or like parts in conjunction there-
with, and I modify the construction and arrangement of the chamber with its float,
valve, and fittings, to suit particular requirements without departing from the
essential features of my invention.

Improvements relating to Steam Heating Apparatus.
I, HENRY MAXSON WILSON. of Prudential Assurance Buildings, Mosley
Street, Newcastle-on-Tyne, in the County of Northumberland, Engineer, (being a
communication from J. Langridge, Engineer, of Yokohama, Japan,) 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:-
This invention relates to improvements in steam heating apparatus, my object
being to construct and arrange convenient and simple appliances for automatically
effecting the removal of the water formed by condensation, and for regulating the
supply of steam.
In the application of my invention to a steam heater for the purpose of heating
the atmosphere within a building or for other purposes, I connect to the radiating
pipes or like parts a condensed steam chamber or vessel. This chamber or vessel
is preferably of a circular configuration and contains a hollow float, constructed
from thin copper sheeting or other metal and having at its lower end a valve, for
regulating the discharge of the water or condensed steam. At the upper end of
the chamber I provide a guard plate having a screw plug inserted at its centre for
the purpose of regulating the lift of the valve, a hole being formed through the plug
for the purpose of receiving the guide stem attached to the upper end of the float.
The valve attached to the lower end of the float is contained within a chamber
into which the water or condensed steam is admitted by perforations through its
walls.
On the admission of steam to the chamber or vessel it becomes gradually
condensed through loss of temperature. The accumulating water causes the float
to rise and thus to lift the valve from the mouth of the discharge pipe, and so
permit of the escape of the water from the chamber. I prevent the entire closing
of the valve on the descent of the float by means of the regulating screw plug in
the guard plate at the upper end of the chamber, or by forming a small hole or
passage through or past the valve sufficient to maintain the required movement or
circulation of steam through the heater.
I sometimes take advantage of the expansion and contraction of the float under
the influence of the steam and water, to allow the valve to close or almost close
the aperture when the chamber is at a sufficiently high temperature, but to be
lifted on cooling to permit of discharge froin the chamber.
I sometinies employ my condensed water chamber with valve and fittings as an
independent heater, without the use of radiators or like parts in conjunction there-
with, the heat being then radiated from the exterior surface of the chamber and
I modify the construction and arrangement of the chamber with its float, valve
and fittings, to suit particular requirements without departing from the essential
features of my invention.
To illustrate the arrangement of parts which I preferably employ in carrying
my invention into effect, I append hereunto two sheets of explanatory drawings to
be hereinafter referred to.
Figure 1, Sheet 1 is a sectional clevation, and Figure 2 a front elevation of my
improved heater, automatic regulator, or draining and circulating apparatus.
Figure 3 Sheet 2 is a part sectional elevation representing a modified form of the
upper regulating valve and attachments.
Figure 4 is an inverted plan of the top cover employed with the form of upper
regulating valve and attachments illustrated at Figure 3, and
Figure 5 is a plan of the bottom plate suitable for either forms of the heater
and regulator.
When employed upon ship-board, the circular pipe or chamber A is placed in

page_text: the engine room or other convenient and suitable position. The top cover B of the
chamber A is provided with an inlet C for forming the connection with the
radiators or heating apparatus throughout the vessel. The water of condensation
falls from such apparatus into the chamber A and as it fills the chamber the
float D gradually rises, lifting or opening the lower valve E and forcing the upper
valve Fou to its seating. The water then escapes from the chamber through the
outlet I and may be passed into the condenser or hot well of the engines and returned
to the boilers by means of the feed pumps.
The float D sinks on the withdrawal of the water, closing the lower valve E and
opening the upper valve F, but such closing does not occur until nearly the whole
of the water has been discharged from the chamber A the upper valve F being
kept upon its seating by the pressure within the chamber until the weight of the
float is sufficient to overcome the un-balanced pressure upon the valve.
valve E is prevented from pounding upon its seating by means of the perforated
inverted dish H.
The
The bottom valve E being thus closed and the upper valve F opened the steam
circulates through the heating apparatus and passes out through the outlet G, and
the expansion of the float D and rod D¹ produced by the heat of the steam causes
the valve F to be nearly closed on to its seating, the valve being then only
sufficiently open to maintain the required movement or circulation of the steam,
without undue or wasteful consumption of the same.
The float D is preferably formed of thin corrugated metallic plates, and thus
possesses lightness with considerable strength and sufficient elasticity to permit it
to yield in the event of both valves being in close contact with their seatings..
The rod D is made of a metal or alloy having a high co-efficient of expansion,
and to increase the movement of the valve produced by the expansion I sometimes
connect the end of the rod to a lever such as J illustrated at Figures 3 and 4.
The cross bar K (Figure 1) attached to the rod D₁ serves as a guiding piece and
as a stay or stiffener.
The valve seating E¹ of the valve E can be adjusted in position by the screw
thread formed at its outer end, and in the cross head L, which is secured by the
side rods M M².
When using high pressure steam in the heating apparatus I sometimes employ a
rod or rods without the float D, the regulation of the valve being then effected
only by the expansion and contraction of the rod or rods.
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 ;-
1. In heating apparatus the method of automatically effecting the removal of the
condensed steam or water and providing for the necessary circulation without waste
of the steam substantially as herein described.
2. In heating apparatus the combination of the float D with valves E and F
substantially as and for the purposes herein before described and as illustrated in
the accompanying drawings.
3. In heating apparatus the combination of the valve scat E' with crosshead L
and rods M M substantially as and for the purposes hereinbefore described and as
illustrated in the accompanying drawings.
4. The improved general construction and arrangement of the automatic heating
regulator substantially as and for the purposes hereinbefore described and as
illustrated in the accompanying drawings.
