Year: 1857

page_text: LETTERS PATENT to Richard Furnival, of Manchester, in the County of
Lancaster, Engineer, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR CUTTING PAPER, CARDBOARD, AND OTHER.
SIMILAR ARTICLES."
Sealed the 18th June 1858, and dated the 19th December 1857.
PROVISIONAL SPECIFICATION left by the said Richard Furnival at the
Office of the Commissioners of Patents, with his Petition, on the 19th
December 1857.
I, RICHARD FURNIVAL, of Manchester, in the County of Lancaster, Engi-
neer, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CUTTING PAPER, CARDBOARD, AND
OTHER SIMILAR ARTICLES," to be as follows:-
My improvements in machinery for cutting paper, cardboard, &c., is
designed for the purpose of cutting through a pile or thickness of paper, or
other substance, with an easy and clean cut; which is produced by imparting
to the cutting knife or blade a reciprocating motion in a horizontal lateral
direction across the pile, simultaneously with or during the time of the descent
of the knife through such pile; this may be effected by a vertical eccentric or
heart-shaped shaft connected with the knife or other equivalent substitutė
which will produce the required motion, and may be connected with and
actuated by the shaft employed to cause the descent of the knife through the
paper or other material.

by the said Richard Furnival in the Great Seal Patent Office on the
19th Juno 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
FURNIVAL, of Manchester, in the County of Lancaster, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twenty-first
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Richard Furnival, Iler especial 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 there-
after 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 "CERTAIN IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR CUTTING PAPER, CARDBOARD, AND OTHER
SIMILAR ARTICLES," upon the condition, amongst others, that I, the said
Richard Furnival, by an instrument 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 per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):-
My improvement in machinery for cutting paper, cardboard, &c., is
designed for the purpose of cutting through a pilo
or thickness of paper, or
other substance, with an easy and clean cut, which is produced by imparting
to the cutting knife or blade a reciprocating motion in a horizontal lateral
direction across the pile, simultaneously with or during the time of the descent
of the knifo through such pile; this may be effected by a vertical eccentric or
vertical heart-shaped shaft, or other equivalent substituto connected with the
knife which will produce the required motion, and may be connected with and
.actuated by the shaft employed to cause the descent of the knife through the
paper or other material.

page_text: 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 two inches to a foot, having similar letters of reference marked upon
corresponding parts of the apparatus.
Fig. 1 is a front elevation of the apparatus, a portion being in section,
shewing the arrangement of mechanism for driving and also for imparting to
the knife or blade the necessary horizontal lateral reciprocating motion during
the descont, and Fig. 2 is a side view of the same. In Fig. 1, a, a, is the
framing of the machine, in which is supported the gearing b, b, b, for turning
the cranks c, c, by which means (or by rack and pinion) the vertical rise and
fall of the knife d is effected, by means of the connecting rods e, e.
The pile
or thickness of paper or cardboard, &c., to be cut is placed upon the ordinary
table f, and the blade or bar g being lowered thereupon, the knife is caused
to descend by turning the handle wheel h, and by this means motion is given
to the mitre wheels i, i, one of which turns the vertical eccentric shaft k,
which passes between bowls in the cross head supporting the knife, and thus
causes the said knife to partake of a horizontal reciprocating motion during
its descent through the pile of paper, &c., and thereby effecting a cleaner cut
than bitherto.
Having now described the nature of my said Invention, together with the
method of performing the same, I would remark in conclusion, that I claim
as my Invention cutting a pile or thickness of paper, cardboard, and other
similar articles, by means of a knife or blade to which a horizontal continuous
reciprocating motion is imparted during its cutting descent to effect a more
perfect and clean cut, either by the novel and particular means or arrange-
ment of the machinery or apparatus herein-before described, set forth, and
fully exhibited in the Drawings attached, or by any other equivalent arrange-
ment of mechanism.
In witness whereof, I, the said Richard Furnival, have hereunto set
my hand and seal, this Eighteenth day of June, in the year of our
Lord One thousand eight hundred and fifty-eight.
KICH FURNIVAL. (L.S.)
