66, Chancery Lane, in the County of Middlesex, Civil Engineer,
for the Invention of "AN IMPROVED COMPOSITION TO BE USED FOR THE
MANUFACTURE OF DRAIN PIPES AND OTHER ARTICLES, AND AS A SUBSTITUTE
FOR ARTIFICIAL - STONE."-A communication from abroad by John

America.

PROVISIONAL SPECIFICATION left by the said Henry Edward
Newton at the Office of the Commissioners of Patents, with his
Petition, on the 3rd May 1872.
I, HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "AN IMPROVED COMPOSITION TO BE.
USED FOR THE MANUFACTURE OF DRAIN PIPES AND OTHER ARTICLES, AND AS A
SUBSTITUTE FOR ARTIFICIAL STONE," to be as follows :—
Pipes, tiles, and artificial stone made of compositions of sand and clay
or other mineral matters and rosin have been liable to the objection that

page_text: in hot weather or when subject to the action of hot water they become
soft. This Invention relates to such compositions, and its object is to
render such compositions hard at all ordinary temperatures, and to this
end it consists in the addition to such compositions of sufficient lime,
strontia, baryta, or magnesia to combine chemically with the rosin,
thereby forming with it a compound which will remain hard at a tem-
perature of nearly 300° Fahrenheit.
In carrying out this Invention the rosin is melted by heating to
about 300° Fahrenheit; hot sand is then put into the melted rosin
and the two are well stirred together; to this mixture is added hot
kaolin or fire-clay, and the whole mass is stirred till thoroughly incor-
porated; lime having been previously air slacked is also heated and
is then put into the mixture and stirred in till thoroughly distributed.
A small quantity of sulphur may be added, but this is not essential. .
The mixture while still hot is packed or rammed tightly into moulds 1
of the required form for the articles to be produced, and when cold
it sets and hardens. The lime combining chemically, with the rosin
forms rosinato of lime, which remains hard at a temperature much
higher than that of boiling water..
Any other form of natural silicate may be substituted for sand in this 2
composition.
SPECIFICATION in pursuance of the conditions of the Letters Patent, g
filed by the said Henry Edward Newton in the Great Seal
Patent Office on the 1st November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of May, in the year of
our Lord One thousand cight hundred and seventy-two, in the thirty-

page_text: fifth -year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Henry Edward Newton, Her special
licence that I, the said Henry Edward Newton, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Edward
Newton, 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
"IMPROVED COMPOSITION TO BE USED FOR THE MANUFACTURE OF Drain Pipes
AND OTHER ARTICLES, AND AS A SUBSTITUTE FOR ARTIFICIAL STONE," being a
communication to me from abroad by John Anderson, of the City and
State of New York, United States of America, upon the condition
(amongst others) that I, the said Henry Edward Newton, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and scals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Scal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say) :-
Pipes, tiles, and artificial stone made of compositions of sand and clay
or other mineral matters and rosin have been liable to the objection that
in hot weather, or when subject to the action of hot water, they become
soft. This Invention relates to such compositions, and its object is to
render such compositions hard at all ordinary temperatures, and to this
end it consists in the addition to such compositions of sufficient lime,
strontia, baryta, or magnesia to combino chemically with the rosin,
thereby forming with it a compound which will remain hard at a tem-
perature of nearly three hundred degrees Fahrenheit.
In carrying out this Invention the rosin is first melted by heating to
about three hundred degrees Fahrenheit; hot and perfectly dry sand is
then put into the melted rosin, and the two are well stirred; to this
mixture is added heated kaolin or fire-clay, and the whole mass is stirred
