AN IMPROVED MACHINE FOR CUTTING METAL, ALSO APPLICABLE TO CUTTING OTHER SUBSTANCES."
Year: 1862

page_text: LETTERS PATENT to Felix Tussaud, of Paris, France, but temporarily
of No. 105, Marylebone Road, in the County of Middlesex, Engineer,
for the Invention of "AN IMPROVED MACHINE FOR CUTTING METAL, ALSO
APPLICABLE TO CUTTING OTHER SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Felix Tussaud at the Office
of the Commissioners of Patents, with his Petition, on the 3rd November
1862.
I, FELIX TUSSAUD, of Paris, France, but temporarily of No. 105, Mary-
lebone Road, in the County of Middlesex, Engineer, do hereby declare the
nature of the said Invention of "AN IMPROVED MACHINE FOR CUTTING METAL,
ALSO APPLICABLE TO CUTTING OTHER SUBSTANCES," to be as follows:-
My Invention consists in an improved construction or arrangement of
circular metal cutting machines. by which sheets of metal, cardboard, leather,
and other materials of great width and length may be divided continuously,
and curved or round shapes may be cut out, and is as follows:-For cutting
in the middle of sheets of metal and other materials the ordinary circular
cutters having their edges bevilled or not as required, and slightly crossing
-cach other as usual, are mounted at the extremity of two long shafts or axles
suitably supported, the length of the axles varying according to the length of

page_text: the sheet to be cut. A way or groove is formed in the framework of the
machine for the passage of the sheets of cut metal or other material, so that
with a machine of small dimensions large sheets of metal or other like
substances may be divided in the middle. For cutting curved or round forms
of small or large radius the upper cutter is vertical, and worked by the motive
power, and the axles of the lower cutter, which are independent of the
mover, are articulated so as to be adjustable at any angle to the upper
cutter.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Felix Tussaud in the Great Seal Patent Office on the 1st
May 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FELIX
TUSSAUD, of Paris, France, but temporarily of No. 105, Marylebone Road,
in the County of Middlesex, Engineer, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third. day of November, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Felix Tussaud, Her special licence that I, the said Felix
Tussaud, my executors, administrators, and assigns, or such others as I, the
said Felix Tussaud, 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 "AN IMPROVED
MACHINE FOR CUTTING METAL, ALSO APPLICABLE TO CUTTING OTHER SUBSTANCES,"
upon the condition (amongst others) that I, the said Felix Tussaud, 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 is 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 Felix Tussaud, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: statement, reference being had to the Drawing hereto annexed, and to the
figures and letters marked thereon, that is to say:-
:
My Invention consists in an improved construction or arrangement of
circular metal cutting machines by which sheets of metal, cardboard, leather,
and other materials of great width and length may be divided continuously,
and curved or round shapes may be cut out, and is as follows:- For cutting
in the middle of sheets of metal or other material the ordinary circular
cutters, having their edges bevilled or not as required, and slightly crossing
each other as usual, are mounted at the extremity of two long shafts or axles
suitably supported, the length of the axles varying according to the length of
the sheet to be cut. A way or groove is formed in the framework of the
machine for the passage of the cut metal or other material, so that with a
machine of small dimensions large sheets of metal or other material may be
divided in the middle. For cutting curved forms of small or large radius the
upper cutter is vertical and is worked by the motive power, the axles of the
lower cutter are independant of the mover, and are articulated so as to be
adjustable at any angle to the upper cutter.
The annexed Drawing represents a cutting machine with two circular
blades or cutters.
a is the upper cutter supported at any beight upon a proper carriage,
and which may be varied either by set screws, an excentric, or any other
suitable contrivance, and is worked by the motive power. The lower cutter b
is independant of the mover, and constructed so that it can be adjusted at any
angle to the upper cutter; it is supported by a moveable carriage c, having a
longitudinal groove d and bolts e, which said bolts pass into another groove f
cut in the framework of the machine. By this arrangement the lower cutter
can be placed in any desired position. If the upper cutter is placed vertically
and the lower one horizontally, it will be easy to cut out small circumferences,
but if on the contrary the lower cutter is made to take all the angles existing
between the horizontal and vertical lines, it will be in the best positions for
cutting all kinds of circumferences. This arrangement permits of cutting a
notch in a plate and of preserving the washer at the same time.
To cut the ends of pipes I use the arrangements represented at Figure 5,
in which the part h, is suppressed and to bring the machine to its working
condition it is only necessary to draw close the part fixed by bolts. I also
make use of cutters of different diameters, that is to say, that according to
circumstances I employ a lower cutter smaller than the upper one.
In some
instances also I make the upper cutter moveable, at the same time permanently
fixing the lower one.

page_text: Having now described the nature of my said Invention, and in what
manner the same is to be performed, I. wish it to be understood that I
do not confine myself to the precise details herein laid down; but what I
claim is,
-
First, the arrangements for varying the inclination and diameter of either of
the cutters, in the manner herein-before described and represented in the
annexed Drawing.
Secondly, the employment of cutters of different dimensions, as herein-
before described.
In witness whereof, I, the said Felix Tussaud, have hereunto set my
hand and seal, this Twenty-ninth day of April, in the year of our Lord
One thousand eight hundred and sixty-three.
TUSSAUD. (L.S.)
Witness,
