PROVISIONAL SPECIFICATION left by the said Job Day and William
Wells Osgerby at the Office of the Commissioners of Patents, with
their Petition, on the 18th July 1874.
We, JOB DAY and WILLIAM WELLS OSGERBY, both of Brigg, in the
County of Lincoln, do hereby declare the nature of the said Invention
for "AN IMPROVED COMPOSITION FOR THE REMOVAL AND PREVENTION OF THE
INCRUSTATION IN STEAM BOILERS," to be as follows:-
This Invention relates to certain improvements upon a composition
for such purposes for which Letters Patent were granted to Robert
Arber Ray, of Brigg, in the County of Lincoln, No. 2132, dated 17th
June 1873, of which Letters Patent we are sole proprietors.

page_text: Hudson's concentrated extract of soap,
Black lead, and
Borax.
Now we have discovered that in place of Hudson's concentrated
extract of soap other extracts of soap will answer the same purpose;
and a mixture of soda and common soap, or other similar saponaceous
mixture or compound, may be employed with advantage in combination
with the black lead and borax, and will be more economical in cost.
Our Invention therefore consists in forming a composition for the
removal and prevention of incrustation in steam boilers by the com-
bination of black lead and borax with a mixture of soda and common
soap, or any other similar saponaceous mixture, or compound or extract
of soap not hitherto employed for such purpose; and the proportions in
which we propose to employ the said ingredients and the manner of
using the same will be similar to those mentioned in the Specification
of the said Letters Patent above referred to.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Job Day and William Wells Osgerby in the
Great Seal Patent Office on the 16th January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOB DAY
and WILLIAM WELLS OSGERBY, both of Brigg, in the County of Lincoln,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 2
Letters Patent, bearing date the Eighteenth day of July, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said Job Day and William
Wells Osgerby, Her special license that we, the said Job Day and a
William Wells Osgerby, our executors, administrators, and assigns,
or such others as we, the said Job Day and William Wells Osgerby,
our executors, administrators, and assigns, should at any time

Now we have discovered that in place of. Hudson's concentrated
extract of soap other extracts of soap will answer the same purpose, and
a mixture of soda and common soap, or other similar saponaceous
mixture or compound may be employed with advantage in combination
with the black lead and borax, and will be more economical in cost,
and that the addition of pearlash to the composition is an improvement.
Our Invention therefore consists in forming a composition for the
removal and prevention of incrustation in steam boilers by the com-
bination of black lead and borax (either with or without pearlash) with

referred to.

Having now described the nature and object of our said Invention,
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, we wish it to be understood that
we claim as our Invention the forming a composition for such purposes
by a combination of black lead and borax (either with or without pearl-
ash) with other extracts of soap or dry soaps in place of Hudson's
concentrated extract of soap, or with a mixture of soda and common
or other soap, or with any other similar saponaceous mixture or com-
pound of a like nature.
