Gedge and Son, of No. 11, Wellington Street, Strand, in the
County of Middlesex, Patent Agent, for the Invention of "AN
IMPROVED MACHINE INTENDED TO DIVIDE, BREAK, OR CRUSH ALL SUBSTANCES

communication from abroad by Eugène Anduze, of 15, Passage

PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition,
on the 26th February 1868.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son,
5 of No. 11, Wellington Street, Strand, in the County of Middlesex,
Patent Agent, do hereby declare the nature of the said Invention for
"AN IMPROVED MACHINE INTENDED TO DIVIDE, BREAK, OR CRUSH ALL SUBSTANCES
CAPABLE OF BEING TRITURATED, MORE ESPECIALLY BONES AND HORNY SUBSTANCES

page_text: OF EVERY KIND, FOR CONVERTING THEM INTO MANURE," a communication to
me from abroad by Eugène Anduze, of 15, Passage des Petites Ecuries,
Paris, France, Manufacturer, to be as follows:-
This machine is composed of two cast-iron plates, the one fixed the
other movable. Each plate carries a cast-iron or steel crown strongly
fitted to it by 4 iron bolts, each crown being furnished with quadran-
gular and conical teeth arranged with precision and in such wise that
those of the upper plate set or take very exactly into those of the lower
plate, and vice versa. The movable or running plate, which works
at a speed of about 700 revolutions a minute, is beneath, and the upper
or fixed plate is strongly secured to two wooden cross pieces by four
bolts. The running plate is fixed by a wedge to a vertical iron shaft,
which also passes through the fixed plate to maintain it in perfect
harmony with the running plate and prevent deviation, which would
inevitably lead to the immediate breakage of the machine. On the
upper or fixed plate between the crown and the axle an opening is
made provided with a hopper, by which the substance to be treated
is introduced, so that it falls perpendicularly on the running plate,
which in its rotation throws and divides the substance between the
crowns. The teeth of these crowns are thinly set in the inner circle
in order to facilitate the introduction of the material, which there begins
to receive a first shock or division, after which it penetrates more
easily towards the outer sets of teeth, which becoming progressively
more and more compact complete the trituration and eject the material
on the exterior in the state of small broken remains and powder.
It will be understood that this machine triturates not only substances
intended to be used as manure, but all kinds of substances susceptible of
trituration.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Gedge in the Great Seal Patent
Office on the 25th August 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of the Firm of John Gedge and Son, of No. 11,
Wellington Street, Strand, in the County of Middlesex, Patent Agent,
send greeting.

Letters Patent, bearing date the Twenty-sixth day of February, in the
year of our Lord One thousand eight hundred and sixty-eight, in
the thirty-first year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said William Edward Gedge,
Her special licence that I, the said William Edward Gedge, my exe-
cutors, administrators, and assigns, or such others as I, the said William
Edward Gedge, 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, excrcise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "AN IMPROVED MACHINE INTENDED TO DIVIDE, BREAK, OR CRUSH ALL
SUBSTANCES CAPABLE OF BEING TRITURATED, MORE ESPECIALLY BONES AND HORNY
SUBSTANCES OF EVERY KIND, FOR CONVERTING THEM INTO MANURE," a com-
munication to me from abroad by Eugène Anduze, of 15, Passage des
Petites Ecuries, Paris, France, Manufacturer, upon the condition
(amongst others) that I, the said William Edward Gedge, 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 William Edward Gedge, 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, reference being had to the accom-
panying Sheet of Drawing forming part of this Specification, and to the
figures and letters of reference placed thereon -
This machine, termed by the Inventor a "crusher," is composed of
two cast-iron plates A, A¹, the one fixed the other moveable. Each
plate carries a cast-iron or steel crown B firmly attached by four iron
bolts C. Each crown is furnished, as shewn at Fig. 1, with quadrangular
and conical teeth D arranged with precision and in such wise that those
of the upper plate take or set very exactly within those of the lower
plate, and vice versa. The moveable or running plate, which works at
speed of, say, 700 revolutions a minute, is beneath, and the upper or

page_text: fixed plate is securely held on two wooden cross pieces by four bolts.
The running plate is fixed by a wedge or key F to a vertical iron
shaft E, which also passes through the fixed plate to keep it in perfect
accord with the running plate, and prevent any deviation which would
inevitably result in the immediate breakage of the machine. On the
upper or fixed plate between the crown and the axle.an opening is made
provided with a hopper G, by which the raw material is introduced,
falling perpendicularly on the running plate which in its rotation
throws and divides the material between the crowns B. The teeth of
these crowns are thinly sewn in the inner circle (see Fig. 2) to facilitate.
the introduction of the material, which there begins to receive a first
shock and a first division or breakage, after which it penetrates more
easily towards the outer teeth, which becoming progressively more
compact, complete the trituration and throw out the material in the state
of small broken pieces and powder.
This improved machine or crusher being naturally capable of
triturating all matters susceptible of trituration, claim is made to its
exclusive use in every case.
On the Drawing Fig. 1 is an elevation and half section of the machine
following the broken line H, I, J, K; Fig. 2, plan of the crushing
machine, the fixed plate being removed to show the details of the
running plate; and Fig. 3, plan and section at L, M, of the fixed
plate.
In witness whereof, I, the said William Edward Gedge, have
hereunto set my hand and seal, this Twenty-fifth day of August,
in the year of our Lord One thousand eight hundred and sixty-
