Lincoln, for the Invention of "AN IMPROVED COMPOSITION POR REMOVING
AND PREVENTING SCALE OR INCRUSTATION IN STEAM BOILERS."
Scaled the 9th December 1873, and dated the 17th June 1873.
PROVISIONAL SPECIFICATION left by the said Robert Arber Ray at
the Office of the Commissioners of Patents, with his Petition, on
the 17th June 1873.
I, ROBERT ARBER RAY, of Brigg, in the County of Lincoln, do
hereby declare the nature of the said Invention for "AN IMPROVED.
COMPOSITION FOR REMOVING AND PREVENTING SCALE OR INCRUSTATION IN STEAM
BOILERS," to be as follows:-
-
My Invention relates to an improved composition for removing and
prevénting scale or incrustation in steam boilers.
The composition consists of the following ingredients:-1 lb. Hudson's
concentrated extract of soap; lb. blacklead; 1 oz. borax; without
however limiting myself to the exact proportions indicated.

page_text: The above are reduced to powder and mixed well together, care being
taken that no lumps remain. The mixture is dissolved in cold water in
the proportion of about 1lb. to the gallon (more or less).
The above are reduced to powder and mixed well together, care being

the proportion of about 1 lb. to the gallon (more or less).
A suitable quantity of this composition is to be put in the boiler, the
amount required increasing with the power of the boiler.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Arber Ray in the Great Seal Patent Office
on the 17th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
ARBER RAY, of Brigg, in the County of Lincoln, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of June, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Robert Arber Ray, Her special licenco
that I, the said Robert Arber Ray, my, executors, administrators, and
assigns, or such others as I, the said Robert Arber Ray, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
COMPOSITION FOR REMOVING AND PREVENTING SCALE OR INCRUSTATION IN STEAM
BOILERS," upon the condition (amongst others) that I, the said Robert
Arber Ray, my, executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to bo
filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the, said Robert Arber Ray, do hereby declare

page_text: performed, to be particularly described and ascertained in and by the
following statement, that is to say :—
My Invention relates to an improved composition for removing and
effectually preventing the formation of scale or incrustation in all classes
3 of steam boilers.
The composition consists of the following ingredients, namely:-
Hudson's concentrated extract of soap, blacklead, and borax in the
following relative proportions:-Hudson's extract 1 lb.; blacklead lb. ;
borax 1 oz.
) The proportions indicated are those which I find answer best for the
purpose, but I do not limit myself to these exact proportions as such
may be varied more or less. :
The said ingredients are reduced to powder and mixed well together,
care being taken that no lumps remain. The mixture is then dissolved
5 in cold water in the proportion of about one pound to the gallon (more
or less).
For removing incrustation a suitable quantity of this composition is
to be put into the boiler before cleaning it out, the amount required
increasing with the power of the boiler and the quality of the water.
▸ Thus for removing incrustation in marine boilers for every 50 nominal
horse-power I use one pound of the composition three times per week,
if working continuously, or one half this quantity if working. by day
only. A smaller quantity will afterwards be found sufficient to keep the
boilers clean.
For stationary boilers for every 40 nominal horse-power I use one
pound of the composition once a week to remove incrustation, and a
smaller quantity afterwards to keep them clean.
For locomotive boilers if washed out twice a week half a pound of
the composition is put in each time of filling up; and for portable
boilers half a pound is put in two or three days before cleaning out.
No priming whatever nor damage to the plates is caused by the use
of this improved boiler composition, and the boilers are rendered much
more durable. By its use also steam is softened and purified and rust is

page_text: Having described the nature of the Invention, and the manner of
performing the same, I declare that what I claim as the Invention to
be protected by the herein-before in part recited Letters Patent is,
the improved composition consisting of the ingredients herein-before
mentioned, substantially as and for the purpose specified.
In witness whereof, I, the said Robert Arber Ray, have here-
unto set my hand and seal, this Fifteenth day of December, in
the year of our Lord One thousand cight hundred and seventy-
three.
