IMPROVE- A PORTA AT THE "
Year: 1873

page_text: LETTERS PATENT to Frederick Liverati Rovedino, of 4, Botolph Lane,
in the City of London, Gentleman, for the Invention of "IMPROVE-
A PORTA AT THE "
PROVISIONAL SPECIFICATION left by the said Frederick Liverati
Rovedino at the Office of the Commissioners of Patents, with his
Petition, on the 24th April 1873.
I, FREDERICK LIVERATI ROVEDINO, of 4, Botolph Lanc, in the City of
London, Gentleman, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL FUEL," to be as
follows:-
This Invention relates to a novel combination of cheap refuse
materials, namely, coal dust, small coal, cinders, peat, wood shavings,
wood chips, sawdust, or other cheap material cemented together by
means of a melted preparation of pitch, rosin, asphalte, or other
inflammable adhesive substance upon a framework of wood, or other

page_text: material arranged in the form of a quadrangle or polygons of any
number of sides, for which purpose I take four, five, six, or more
portions or separate pieces of wood or other material, and connect them
temporarily alongside of each other; each piece I alternately connect or
hinge at a little distance from the top thereof to the piece of wood con-
tiguous to it on the one side, and at the bottom to the other piece that
is situated on the other side thercof by means of string, wire, pins, rivets,
or other fastenings; the framework of wood is completed by expanding
cach piece of wood or other material at an angle upon that piece, that
is immediately under it, and then passing the last end or top piece
of wood or other material underneath the first or bottom piece and
securing the two ends together so as to produce the required shape; the
fuel thus made is then ready for use. By means of this framework I
give to the materials employed a cohesion that of themselves they
would not possess if they were simply moulded into the before mentioned
forms, which is most advantageous for the thorough ventilation and
combustion of the fuel. Increased solidity of the blocks of fuel for
storage or handling may also be obtained by subsequent compression
in warm moulds of metal of the various shapes mentioned before.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Frederick Liverati Rovedino in the Great Seal
Patent Office on the 1st October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
LIVERATI ROVEDINO, of 4, Botolph Lane, in the City of London;
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of April, 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 Frederick Liverati Rovedino, Her special
licence that I, the said Frederick Liverati Rovedino, my executors,
administrators, and assigns, or such others as I, the said Frederick
Liverati Rovedino, 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

page_text: make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for i IMPROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL FUEL," upon the
condition (amongst others) that I, the said Frederick Liverati Rovedino,
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
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 Frederick Liverati Rovedino, do
hereby declare the nature of my 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 :—
•
My Invention relates to a novel combination of cheap or refuse
materials, namely, coal dust, small coal, cinders, peat, wood shavings,
wood chips, sawdust, or other cheap material cemented together by
means of a melted preparation of pitch, rosin, asphalte, or other
inflammable substance upon a framework of wood or other material
arranged in the form of a quadrangle or polygons of any number
of sides, for which purpose I take four, five, six, or more portions
or separate pieces of wood or other material, and arrange them
temporarily alongside of each other; each piece I then alternately
connect or hinge at a little distance from the top thereof to the piece of
wood or other material contiguous to it on the one side, and at the
bottom to the other piece that is situated on the other side thereof by
means of string, wire, pins, rivets, or other fastenings; the framework of
wood or other material is completed by expanding each piece of wood or
other material at an angle upon that piece that is immediately under it,
and then passing the last end or top piece of wood or other material
underneath the first or bottom piece, and securing the two ends together
so as to produce the required shape. The framework thus completed
I dip into or cover with a melted preparation of pitch, rosin, asphalte, or
other inflammable substance, upon which surface whilst plastic I sift
over or press thercon coal dust, small coal, cinders, peat, wood shavings,
wood chips, sawdust, or other cheap material. The fuel thus made is
then ready for use. By these means I give to the materials employed a
degree of cohesion they would not possess if they were simply moulded

page_text: into the before mentioned forms, which are most advantageous for the
thorough ventilation and combustion of the fuel. Increased solidity of
the pieces of fuel for storage or handling may also be obtained by
subsequent compression in warm moulds of metal or other suitable
material of the various shapes mentioned.
In witness whereof, I, the said Frederick Liverati Rovedino, have
hereunto set my hand and seal, this Twenty-ninth day of
September, in the year of our Lord One thousand eight hundred
and seventy-three.
F. LIVERATI ROVEDINO. (L.S.)
