IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CUTTING PAPER, TEXTILE FABRICS, AND OTHER ARTICLES OR MATERIALS
Year: 1860

page_text: LETTERS PATENT to Richard Furnival, of Manchester, in the County of
Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR CUTTING PAPER, TEXTILE FABRICS, AND OTHER ARTICLES OR
MATERIALS."
Sealed the 10th May 1861, and dated the 14th November 1860.
PROVISIONAL SPECIFICATION left by the said Richard Furnival at the
Office of the Commissioners of Patents, with his Petition, on the 14th
November 1860.
I, RICHARD FURNIVAL, of Manchester, in the County of Lancaster, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR CUTTING PAPER, TEXTILE FABRICS, AND OTHER
ARTICLES OR MATERIALS," to be as follows:-
My Invention relates to such descriptions of machinery as have hitherto
been employed for cutting paper, cardboard, and some kinds of textile fabrics
wherein a horizontal knife or blade descends vertically through the material to
be cut, and the improvement consists in imparting to the said cutting blade a
diagonal or angular direction during its descent, so that the blade descends
with a vertical and diagonal lateral movement combined, performing the cut
with a "sweep" or in a portion of a circle. This is effected by means of a
crank on the driving wheel or shaft, and a connecting link uniting to the
cutting blade, so that as the crank revolves the required motion is obtained,
the blade being limited and guided by two links or "radiant bars" attached
to the blade, and working in bearings in the framing; the principal feature
of the Invention being to obtain a direct action of the crank upon the blade or
knife in the direction of the cut.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I RICHAR
FURNIVAL, of Manchester, in the County of Lancaster, Engineer, sen
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of November, in the year of our Lord
-One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Richard Furnival, Her special license that I, the said Richard Furnival, my
executors, administrators, and assigns, or such others as I; the said Richard
Furnival, 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 "IMPROVEMENTS IN MACHINERY OR
APPARATUS POR CUTTING PAPER, TEXTILE FABRICS, AND OTHER ARTICLES," upon the
condition, amongst others, that I, the said Richard Furnival, by an instru-
ment in writing under my hand and seal, 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 Richard Furnival, 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
and accompanying Drawings (that is to say):-
My Invention relates to such descriptions of machinery as have hitherto
been employed for cutting paper, cardboard, and some kinds of textile fabrics
wherein a horizontal knife or blade descends vertically through the material to
be cut, and the improvement consists in imparting to the said cutting blade a
diagonal or angular direction during its descent, so that the blade descends
with a vertical and diagonal lateral movement combined, performing the cut
with a "sweep," partaking of a slightly circular course. This effect is obtained. 3
by means of a crank on the driving wheel or shaft, and a connecting link
uniting it to the cutting blade, so that as the crank revolves the required
motion is obtained, the blade being limited and guided by two "links" or

page_text: radial bars" attached to the blade, and having bearings in the upper part of
the framing, the principal feature of the Invention being to obtain a direct
action of the crank upon the blade or cutter in the direction of the cut.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made upon a scale of
about four inches to the foot, and having similar letters of reference marked
upon corresponding parts of the mechanism.
Fig. 1 is a front view of the machine, shewing the "radial bars" and the
method of obtaining the direct action of the crank upon the cutter. In
Figs. 1, 2, a, a, is the framing of the machine, and 6 the cutter or blade,
which is connected to the crank c by means of the "connecting link "d. By
means of the handle e, or other applied motive power, motion is given to the
crank by the spur wheel and pinion f, f, and the bevil gearing g, g, the links
h, h, guiding or limiting the direction of the blade.
Although I have shewn and described an efficient method of obtaining the
direct action of the crank c upon the blade 6, I am fully aware and wish to
state, that the same peculiar motion may be obtained by means of a lever
having a central fulcrum and cam, one end of the lever being attached to the
blade, and the opposite end working in the groove of a suitably formed cam.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim the application of the principle of the novel and peculiar
direct action of a crank upon a cutting blade or blades imparting a vertical
and lateral diagonal movement simultaneously by means of the arrangement
of gearing shewn in the Drawings attached and above particularly described,
in combination with "radial bars," for cutting paper, textile fabrics, and other
materials.
In witness whereof, I, the said Richard Furnival, have hereunto set my
hand and seal, this Ninth day of May, in the year of our Lord
One thousand eight hundred and sixty-one.
RICHARD FURNIVAL. (LS.)
