PROVISIONAL SPECIFICATION left by the said Elizabeth Marriott'
i
at the Office of the Commissioners of Patents, with her Petition,
on the 19th March 1874.
I, ELIZABETH MARRIOTT, of Holloway, in the County of Middlesex,
do hereby declare the nature of the said Invention for "AN IMPROVED
ARTIFICIAL FUEL," to be as follows:—
This Invention relates to the manufacture of an improved artificial">
fuel principally from substances hitherto esteemed of little or no value,
such as ashes and other refuse from dust bins and such like sources.
•
According to this Invention I employ a mixture of ashes and other
refuse, small coal, and peat, which are incorporated with a sufficient

page_text: amount of pitch, tar, or other bituminous matter to bind them together
in a pasty mass, which is then formed in moulds into blocks of con-
venient size, with holes to facilitate combustion.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Elizabeth Marriott in the Great Seal Patent Office
on the 18th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ELIZABETH
MARRIOTT, of Holloway, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of March, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Elizabeth Marriott, Her special licence
that I, the said Elizabeth Marriott, my executors, administrators, and
assigns, or such others as I, the said Elizabeth Marriott, 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, usc, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED ARTIFICIAL
FUEL," a communication to me from abroad by John Thompson Duley,
of Sydney, New South Wales,. upon the condition (amongst others) that
I, the said Elizabeth Marriott, my executors or administrators, by
an instrument in,, writing under my, or their, or one of their hands and.
seals, 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 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 Elizabeth Marriott, 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 :-

This Invention relates to the manufacture of an improved artificial
fuel, composed principally of substances hitherto esteemed, of little or no

page_text: value, such as ashes and other refuse from dust bins and such like
sources.
In carrying out this Invention I may employ a mixture of ashes and
other refuse, small coal, and peat, or any of these, with which is incor-
porated a sufficient amount of pitch, tar, or other bituminous matter to
bind the various substances together in a pasty mass. The mass is then
moulded by any suitable means or machine (such as for instance an
ordinary machine for making perforated bricks) into blocks, perforated
or having rows of holes formed completely through the same, after the
manner of a perforated brick, which blocks are afterwards dried for use.
The holes may be of round, square, diamond, or polygonal form, in rows
or otherwise, but they should be as numerous as it is possible to make
them and yet retain the necessary firmness of the block to enable it to
bear handling.
Blocks of artificial hitherto made with the object of utilizing small
coal and other refuse combustible matters have failed owing to
their great density and consequent slowness of combustion, which
renders them unsuitable for use as a substitute for coal; ¡but these
objections are entirely obviated by perforating the blocks in the manner
described, inasmuch as the perforations afford the amount of ventilation
necessary to maintain the requisite rapidity of combustion..
Having described the nature of the Invention, and the manner of per-
forming the same, I declare that what I claim as the Invention to be
protected by the herein-before in part recited Letters Patent is, per-
forating blocks of artificial fuel substantially as and for the purpose
specified.
In witness whereof, I, the said Elizabeth Marriott, have hereunto
