I ALFRED ROBERTS of Castle Street Tipton in the County of Stafford Engineer
do hereby declare the nature of the said invention for 'IMPROVEMENTS IN
PREVENTING AND REMOVING INCRUSTATION IN BOILERS AND HEATERS to be as
follows:
This invention refers to the cleansing of the inside of boilers and Heaters and
the prevention of incrustation by the application of certain vegetable matters such
as Hay Ensilage tan litter oak bark Horse Chesnut or Irish Moss whether green dry
or decomposed and either in the solid form or as an infusion, to any of which may
be added if desired caustic soda.
I carry this out in the following manner. In an ordinary boiler the vegetable
ingredients are contained in a cage or receptacle of perforated metal laid or
suspended in the boiler The water when hot infuses the ingredients in the cage
prevents incrustation in clean boilers and removes it from foul ones and the
deposit precipitated from the water in the form of mud is discharged by simply
blowing off.
In tubular or flue boilers when a cage cannot be used the infusion is made
independently of the boiler but in connection with it and for this purpose I employ
a small shell or boiler with a pipe leading into it from the feed pipe and another
pipe connecting it with the boiler so that steam may be admitted when required.
There is also a third pipe with a small back valve leading from the infusing apparatus
into the boiler and dipping below the surface of the water. In each of the two
first named pipes is fitted a tap so as to make or stop off connection as required.
At one end of the infusing vessel is an opening covered with an easily removable
lid through which opening the ingredients are introduced.
When charged and closed the apparatus is filled with water by opening the tap
on the pipe leading from the feed pipe This tap is then closed and the one
admitting steam is opened by which the materials are infused. When this has
been done the steam tap is closed and the water tap is opened the water carrying
the infusion into the boiler.

Improvements in Preventing and Removing Incrustation in
Boilers and Heaters.
'I ALFRED ROBERTS of Castle Street Tipton in the County of Stafford Engineer
do hereby declare the nature of my said invention for IMPROVEMENTS IN
PREVENTING AND REMOVING INCRUSTATION IN BOILERS AND HEATERS and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention refers to the cleansing of the inside of boilers and heaters and
the prevention of incrustation by the application of certain vegetable matters such
as hay ensilage tan oak bark or Irish moss whether green dry or decomposed or by
the application of caustic soda, and any of the substances may be applied either in
the solid form or as an infusion.
I carry this out in the following manner, In an ordinary boiler the vegetable
ingredients may be placed loosely or contained in a cage or receptacle of perforated
metal or wood or both combined which receptacle is laid or suspended in the
boiler.
The water when hot infuses the ingredients prevents incrustation in the clean
boilers and removes it in time from foul ones, and the deposit precipitated from the
water in the form of mud is discharged by simply "blowing off."
In
In tubular or flue boilers where a cage or receptacle cannot be used and it is not
thought advisable to put the vegetable in loosely the infusion may be made
independently of the boiler but in connection with it; and for this purpose
I employ a small still or boiler with a pipe leading into it from the feed pipe and
another pipe connecting it with the boiler so that steam may be admitted when
required, there is also a third pipe with a small back valve leading from the
infusing apparatus into the boiler and dipping below the surface of the water.
each of the two first named pipes is fitted a tap so as to make or stop off con-
nection as required At one end of the infusing vessel is an opening covered with
an easily removable lid through which opening the ingredients are introduced.
When charged and closed the apparatus is filled with water by opening the top
on the pipe leading from the feed pipa. This tap is then closed and the one
admitting steam is opened by which the materials are infused When this has been
done, the steam tap is closed and the water tap opened, the water carrying the
infusion into the boiler.
Although I have described one way in which I can introduce the infusion into
tubular or flue boilers I do not confine myself to any particular mode of so doing.

page_text: 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;
The introduction into boilers and heaters of the substances specified or other
vegetable substances of like character for the purpose of preventing and removing
incrustation therein.
