IMPROVEMENTS IN SHARPENING AND DRESSING THE CARDS OF CARDING MACHINES, AND THE CLIPPERS AND CYLINDERS OF SHEARING MACHINES
Year: 1852

page_text: LETTERS PATENT to Mathurin Jean Prudent Moriceau, of 39,
Rue de l'Echiquier, Paris, France, Engineer, for the Invention
of "IMPROVEMENTS IN SHARPENING AND DRESSING THE CARDS OF
CARDING MACHINES, AND THE CLIPPERS AND CYLINDERS OF SHEARING
MACHINES."
Sealed the 7th May 1853, and dated the 26th November 1852.
PROVISIONAL SPECIFICATION left by the said Mathurin Jean
Prudent Moriceau at the Office of the Commissioners of
Patents, with his Petition, on the 26th November 1852.
I, MATHURIN JEAN PRUDENT MORICEAU, of 39, Rue de l'Echiquier,
Paris, France, Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN SHARPENING AND DRESSING THE CARDS
CARDING MACHINES, AND THE CLIPPERS AND CYLINDERS OF SHEARING
MACHINES," to be as follows:-
My Invention consists in the construction of an apparatus for
sharpening cards and clippers without taking them down from the
cylinders in their working position, except, however, for the clippers,
which it is sometimes expedient to remove, and in dressing the

page_text: cylinders of shearing machines in a more perfect manner than has
hitherto been obtained.
The apparatus is composed of a cylindrical grit stone rotating in
a frame set upon a shaft.
The grit stone is moved from one extremity of the cylinder to
the other by a screw set in motion by the same pulley, and at a
much slower rate, which brings the stone with regularity before
the object to be ground.
Fig. 1, a end view of the said apparatus, in which a, is the grit
stone; b, the shaft on which it is set; c, c, a tongue piece enabling the
cylinder a, to turn in the frame d. The pinion n, sets the wheel m,
in motion, which communicates it to the screw e; the latter cogs in
the moveable cross piece f, and causes the cylinder to move right
and left between the sockets g, g; i, i, screws for approaching the
cylinder nearer the objects to be sharpened.

disposed more particularly for sharpening the cards of cotton
cylinders.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said Mathurin Jean Prudent Moriceau in
the Great Seal Patent Office on the 26th May 1853.;
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
MATHURIN JEAN PRUDENT MORICEAU, of 39, Rue de l'Echiquier,
Paris, France, Engineer, send greeting.
WHEREAS 1Ier most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of November,
One thousand eight hundred and fifty-two, in the sixteenth year of
Iler reign, did, for Ierself, Iler heirs and successors, give and grant
unto me, the said Mathurin Jean Prudent Moriceau, Her special
licence that I, the said Mathurin Jean Prudent Moriceau, my
executors, administrators, and assigns, or such others as I, the said
Mathurin Jean Prudent Moriccau, my executors, administrators,

page_text: 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 "IMPROVEMENTS IN
SHARPENING AND DRESSING THE CARDS OF CARDING MACHINES, AND THE
CLIPPERS AND CYLINDERS OF SHEARING MACHINES," upon the condition
(amongst others) that I, the said Mathurin Jean Prudent Moriccau,
by an instrument in writing under my hand and seal, should par-
ticularly 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 Mathurin Jean Prudent
Moriceau, 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 consists in applying a solid mill stone, or suitable
grinding stone, upon a wood or metal cylinder, for setting or sharp-
ening the cards of carding engines, and the blades of shearing or
other similar engines, by which the operation may be performed
without necessitating the removal of any part of the said engines.
The cylinder receives an alternate motion, and is made to work with
regularity in front of the part of the engine which is to be set or
ground. If desired, the cylinder may be constructed of the same
breadth as the engine.
Figure 1. 1, the pulley put in motion by one of the organs of
the carding engine, or by any other suitable power, and causing the
shaft b, to rotate. The cylinder a, is set in the frame d, and the
latter upon the shaft b, and turns with it, being fixed to the shaft
by the pin c.
The pinion n, puts in motion the toothed wheel m, which gives a
rotary motion to the intersected screw e, in the threads of which

page_text: the moveable cross piece f, enters, and thereby causes the cylinder
a, to travel from the socket g, to the socket g'. The two setting
screws, i, serve to bring the cylinder to the parts to be set, or
cause it to recede from them.
Figure 2, represents a side view of an apparatus constructed of
much larger dimensions, and applicable for setting the cards of a
cotton carding engine. In this figure a, a, a, a, represent segments
of mill stone, or of any other suitable stone, mounted on a wheel.
And having now described the nature of my Invention, and the
manner of performing the same, I wish it to be understood that I
do not confine myself to the precise details or mode of operating as
herein-before described, but what I claim as my Invention, and
intend to be protected by the said Letters Patent, is,
The construction of an apparatus for setting or grinding the
cards and blades of carding, shearing, and other similar engines
whilst in the working position, as herein-before described and re-
ferred to in Figures 1, and 2, of the Drawing.
In witness whereof, I have hereunto set my hand and seal, this
Twenty-fourth day of May, in the year of our Lord One
thousand eight hundred and fifty-three.
