I EDWARD METCALF Chemical Manufacturer, N° 10 Canning Street Accrington
in the County of Lancaster do hereby declare the nature of said invention for
"AN IMPROVED COMPOUND FOR PREVENTING CORROSION AND INCRUSTATION IN
STEAM BOILERS" to be as follows:-
To make this preparation I use two articles, which are Soft Soap and Creosote
Oil In the proportions of 20 lbs Soft Soap, to 10 gallons of Creosote Oil.
These two articles are the essential components of my preparation, and I also
use either vegetable or animal matter such as, Horns, Hoofs, Buffalo Hide or Irish
Moss, say about 40 lbs which you place in a vessel or pan and boil till dissolved, in
a sufficient quantity of water, to make a rather thick liquid. When these are
dissolved you put in the Soft Soap and boil together a short time
into a vessel and put in the Creosote Oil, as soon as possible and
are united.
-
You then sieve
agitate till they
This forms the compound preparation which I claim as my invention.
The proportions given are what will answer for most waters, but if for instance
I knew that the water was very soft coming off Moss Land, I should use little
Soap & more Creosote Oil.
On the other hand if the water was very hard, such as comes off Lime stone
districts, I should use more Soft Soap and less Creosote Oil.
By using this new preparation, we preserve the boiler and prevent corrosion.
The Soap having a cleansing effect, and the Creosote Oil in particular (and the
dissolved Horns, Hoofs, Buffalo Hide etc) are of that nature that they go direct to
the Iron and prevent it from corroding and preserve it from the action of the water
which is continually going on in the boiler.
And by thus preventing the action of the water, from making the Iron rough
and porous (keeping it smooth) you prevent any sediment or ingredients in the
water, from adhering to the Boiler and so keep the boiler clean without acting
upon it with injurious chemicals.

I EDWARD METCALF Chemical Manufacturer residing at No 10 Canning Street
Accrington in the County of Lancashire do hereby declare the nature of my
invention for PREVENTING CORROSION AND INCRUSTATION IN STEAM BOILERS and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
The ingredients of the compound are as follows
5
14 Gallons of Creosote Oil
The method of making the compound is the following
I put into an 80 gallon pan, the Horns Hoofs & Irish Moss (I put the moss in
a wrapper to save labour in seiving) and Ash or Alkaline with as much water as
will boil them down to a thick liquid, when they are dissolved and while boiling
I empty the pan, sieving the liquid into a tub or barrel and, as soon as possible add
to this liquid the Creosote Oil and given them a thorough agitation, a slight
chemical action takes place uniting them together.
These are the ingredients & this the method of making the compound I give
in explanation thereof.
(1st) The Creosote Oil being specifically heavier than water, would therefore sink
to the bottom of the boiler but by being united in this manner with the glutinous
matter and alkali we are enabled to distribute a small quantity over the surface of
the plates every day.
(2nd) Its properties are of the nature that it will prevent corrosion & prevent
the action of the water or any ingredient the water contains from operating upon
the plates, making them rough & porous and, by thus keeping a smooth surface on
the plates no sediment or incrustation can adhere to them.
(3) It will not operate upon the plates & valves chemically, but will preserve them ;
I should vary the given proportions according as I knew the quality of the water.
A similar compound can be made from any one of the glutinous materials given,
by being put through, the same process with the Alkali and Creosote Oil.
Having now particularly described and ascertained the nature of my said,
invention, and in what manner the same is to be performed 1 declare that what
I claim is therefore
(1st) The use of the before described glutinous or any other glutinous matter, in
the given or any other proportions united with Alkali & Creosote Oil in the given
or any other proportions, for the making of a compound for Preventing Corrosion
& Incrustation in Steam Boilers.
