Improvements relating to Steam Heaters and Radiator
Regulators."
I, HENRY MAXSON WILSON, of Crown Buildings, Side, Newcastle-on-Tyne, in the
,County of Northumberland, (being a communication from J. Langridge, Engineer,
of Yokohama, Japan), do hereby declare the nature of this invention to be as
follows:-
This invention consists of improvements relating to steam heaters and radiator
regulators such as described in specification No. 20550 of 1894 on which Letters
Patent have been granted.
My improvements consist in the provision of simple means for balancing the
internal float or like part of the heater or radiator regulator and for readily
adjusting the appliance to suit the pressure of steam employed also to provide for
the automatic return of the condensed steam to the boiler or generator.
In the application of my invention I connect the float with a spiral or other
adjustable spring arranged within a supplementary chamber at the steam inlet
end of the apparatus. The connection is preferably formed by means of a rod
extending from the float, or central expansible rod passing through the same,
through a regulating plate against which one end of the spring abuts. By
operating a nut screwed in the outer extremity of the connecting rod, the spring
can be readily adjusted, to suit the particular pressure of steam employed for
heating, in order that the weight of the float shall be supported or suspended from
the spring. I employ a suitable index for indicating the range of pressures within
which the spring may be adjusted.
To provide for the automatic return of the condensed steam to the boiler or
steam generator I mount the regulator at such a height above the boiler as to give
sufficient head for the drop or feed pipe as to cause the pressure due to such head
together with the pressure of steam at the regulator inlet to force the condensed
steam into the boiler. The return of the condensed steam is assisted by the forma-
tion of a partial vacuum within the regulator.

page_text: what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This Invention consists of improvements relating to steam heaters and radiator
regulators such as described in Specification No. 20550 of 1894 on which Letters
Patent have been granted.
My improvements consist in the provision of simple means for balancing the
internal float or like part of the heater or radiator regulator, and for readily
adjusting the appliance to suit the pressure of steam employed; also to provide
for the automatic return of the condensed steam to the boiler or generator.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to:-
Figure 1 is a sectional elevation of the supplementary balancing chamber con-
structed in accordance with this invention.
Figure 2 is an elevation to a smaller scale, illustrating the arrangement and
combination of parts for effecting the automatic return of the condensed steam to
the boiler or generator.
In the application of my invention I connect the float described in the aforesaid
prior specification, with an adjustable spring such as A arranged within the sup-
plementary chamber B (Figures 1 and 2) at the steam inlet end of the apparatus.
The connection is preferably formed by means of a rod extending from the float,
or central expansible rod passing through the same, through a regulating plate D
against which one end of the spring abuts. By operating a nut C₁ screwed on
the outer extremity of the connecting rod C, (to the lower end of which the float
is attached), the spring A can be readily adjusted, to suit the particular pressure
of steam employed for heating in order that the weight of the float shall be sup-
ported or suspended from the spring. I employ a suitable index such as E¹ on the
guide rod for indicating the range of pressures within which the spring may be
adjusted. The guide piston C2 on the rod C fits easily within a chamber formed
as illustrated at Figure 1.
To provide for the automatic return of the condensed steam to the boiler or
steam generator I mount the regulator F (Figure 2) at such a height above the
boiler G as to give sufficient head for the drop or feed pipe H as to cause the
pressure due to such head together with the pressure of steam at the regulator
inlet to force the condensed steam into the boiler. The return of the condensed
steam is assisted by the formation of a partial vacuum within the regulator, and
I also provide a large check valve on the boiler.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
1. In steam heaters and radiator regulators, means for balancing the internal
float or like part and for adjustment to suit the pressure of steam employed, sub-
stantially as described.
2. The arrangement and combination of parts to effect the automatic return of
the condensed steam from a steam heater or radiator regulator, substantially
as described.
