the same is Working under Pressure.
I, RICHARD CHAMBERS, of 16 Holyhead Road, Handsworth near Birmingham,
Iron Works Manager, do hereby declare the nature of this invention to be as
follows:-
Owing to the absence of proper facilities for its introduction into the boiler whilst
working under pressure, the composition employed for the purpose of preventing or
reducing incrustation has hitherto been usually introduced into the boiler previously
to the same being started to work under pressure, after cleaning or otherwise, and no
further supply has been added until the boiler is taken off again. It is manifestly
desirable that the composition be introduced in small quantities at frequent intervals
(say once or twice a day) so as to effect a constant and regular action, and thus the
composition he utilized in the most. economical manner and with the greatest
advantage to the working of the boiler. To effect this purpose, to some extent, the
composition is sometimes supplied with the feed water, but this is an inconvenient
arrangement, and when two or more boilers are working together it is difficult to
ensure that each boiler shall receive its proportionate charge.
Now, the object of this invention is the construction and employinent of apparatus
by which the composition may be introduced into a boiler in successive charges whilst
the same is working under pressure.
An appliance constructed according to this invention, for the above described
purpose, consists of a vessel or chamber in position outside the boiler and above the
level of the water therein, of a suitable lid or cover to such vessel capable of being
securely fixed steam and water tight thereon or of a suitable stop cock or valve in lieu
of such lid or cover, of a pipe from the bottom of such vessel communicating with the
water in the boiler below the level thereof, preferably near the bottom of the boiler, of
a stop cock or valve in such pipe in position to be readily opened and closed by
hand, of a pipe communicating between the vessel (preferably the upper part thereof)
and the steam in the boiler, and of a stop cock or valve in such latter pipe in position
to be readily opened and closed by hand.

page_text: When it is desired to introduce composition into the boiler, the cocks or valves in
the pipes, aforesaid, are both closed, and the lid or cover removed, or the cock or
valve employed in lieu thereof opened; the composition is then poured into the vessel
and the lid or cover, or cock or valve employed in lieu thereof, closed; the cocks or
valves in the pipes, aforesaid, are then both opened and the composition immediately
flows down through the pipe in the bottom of the vessel into the water in the
boiler.
The vessel or chamber may be conveniently mounted on the top of the boiler, with
sufficient space between it and the boiler for the cock or valve in the pipe which
passes down to the water in the boiler.
-
The cover may be conveniently formed as a screw plug, with a suitable cross-bar
handle, and it is preferred to form a cup around the opening in the top of the vessel
to facilitate pouring in the composition.
It is not, of course, essential that the vessel or chamber be fixed outside the boiler,
as it may be fixed inside in such a manner that the lid or cover can be taken off and
replaced from the outside of the boiler, and with suitable rods from the cocks or
valves in the pipes, aforesaid, passing up through packing boxes on the boiler. It is
very much preferred, however, for the sake of convenience and economy and for
avoiding unnecessary impediments within the boiler to fix the vessel or chamber
outside the boiler.

An Appliance for Passing Composition into a Steam Boiler whilst
the same is Working under Pressure:
I, RICHARD CHAMBERS, of Springfield House, Holyhead Road, (formerly of
16 Holyhead Road). Handsworth, near Birmingham, Iron Works Manager, 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,
reference being had to the accompanying drawing, and the letters of reference marked
thereon (that is to say):
-
Owing to the absence of proper facilities for its introduction into the boiler whilst
working under pressure, composition employed for the purpose of preventing or
reducing incrustation has hitherto usually been introduced into the boiler previously
to the same being started to work under pressure, after cleaning or otherwise, and no
further supply has been added until the boiler is taken off again. It is manifestly
desirable that the composition be introduced in small quantities at frequent intervals
(say once or twice a day) so as to effect a constant and regular action, and thus the
composition be utilized in the most economical manner and with the greatest
advantage to the working of the boiler. To effect this purpose, to some extent, the
composition. is sometimes supplied with the feed water, but this is an inconvenient
arrangement, and when two or more boilers are working together it is difficult to
ensure that each shall receive its proportionate charge.
Now, the object of this invention is the construction and employment of apparatus
by which the composition may be introduced into a boiler in successive charges whilst
the same is working under pressure.
An appliance constructed according to this invention, for the above described
purpose, consists of a vessel or chamber in position outside the boiler and above the
level of the water therein, of a suitable lid or cover to such vessel capable of being
securely fixed steam and water-tight thereon, or of a suitable stop cock or valve in
lieu of such lid or cover, of a pipe from the bottom of such vessel communicating with
the water in the boiler below the level thereof, preferably near the bottom of the
boiler, of a stop cock or valve in such pipe in position to be readily opened and closed
by hand, of a pipe communicating between the vessel (preferably the upper part
thereof) and the steam in the boiler, and of a stop cock or valve in such latter pipe in
position to be readily opened and closed by hand.
When it is desired to introduce composition into the boiler, the cocks or valves in
the pipes, aforesaid, are both closed, and the lid or cover removed, or the cock or
valve employed in lieu thereof opened; the composition is then poured into the vessel
and the lid or cover, or cock or valve employed in lieu thereof, closed; the cocks or
valves in the pipes, aforesaid, are then both opened and the composition immediately
flows down into the water in the boiler through the pipe communicating therewith.
This invention will be clearly understood on reference to the drawing berewith,
which is a side elevation, partly in section, of an appliance constructed according to
this invention shewn fixed upon the top of a boiler. A is the vessel or receiver for
the composition, a is a screw plug in the top thereof which is removed for pouring in
the composition, and a cup is formed upon the top of the vessel around the opening for

page_text: the screw plug a, as shewn, in order to facilitate the pouring in of the composition.
A pipe c, having a cock d therein, passes down to within a few inches (say 4 or
5 inches) of the bottom of the boiler B, and a pipe e, having a cock therein,
communicates between the steam space of the boiler and the interior of the vessel A,
preferably near the top thereof, as shewn. A charge of composition is inserted into
the boiler by first removing the screw plug a while the cocks d and fare closed, and
then replacing the plug and afterwards opening the cocks d and f when the
composition flows down the pipe c into the water in the boiler.
A cock g is inserted within the side of the vessel A so that in case there is any
leakage in the cock the steam resulting therefrom may be allowed to escape from
the vessel A previously to the screw plug a being removed, and thus any risk of the
attendant being scalded be avoided.
It is not essential, though it is much preferred, to employ the pipe c communicating
between the bottom of the vessel and the water in the boiler, as the composition may
be allowed, upon opening the necessary cock or valve, to fall through the steam space
into the water. In this case the pipe e should communicate with the interior of the
vessel above the bottom of the composition therein, preferably at the upper part of the
vessel as shewn in the drawing. Neither is it essential that the vessel or chamber be
fixed outside the boiler, as it may be fixed inside in such a manner that the lid or
cover can be taken off and refixed from the outside of the boiler, and with suitable
rods passing up through packing boxes on the boiler by which the necessary cocks
may be worked. It is very much preferred, however, for the sake of convenience and
economy, and for avoiding unnecessary impediments within the boiler, to fix the vessel
or chamber outside the boiler.
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. An appliance for passing composition into a steam boiler, whilst the same is
working under pressure, consisting of a vessel provided with a suitable lid, cover, tap,
or analogous part, which may be opened to receive the composition and be afterwards
closed, such vessel having a communication at or near its lower end with the water
within the boiler and having also a separate communication with the steam space of
the boiler, in combination with means by which such communications may be opened
and closed as desired, substantially as herein described.
2. An appliance for passing composition into a steam boiler, whilst the same is
working under pressure, substantially as described, with reference to the drawing
herewith.
3. An appliance for passing composition into a steam boiler, whilst the same is
working under pressure, consisting of a vessel A with a screw plug a or corresponding
part at the top, in combination with pipes c and e, and cocks or valves d and f, all
substantially as described and shewn by the drawing herewith, for the purpose set
forth.
4. The modification of an appliance for passing composition into a steam boiler,
whilst the same is working under pressure, in which the pipe communicating between
the bottom of the vessel into which the composition is charged and the water in the
boiler is dispensed with, substantially as described.
