Year: 1867

page_text: LETTERS PATENT to William Cotton, of Hebden Bridge, in the County.
of York, for the Invention of "IMPROVEMENTS IN MACHINERY OR APPA-
BATUS FOR CUTTING WOOLLEN AND COTTON CORDUROY OR OTHER SIMILAR
FABRICS."
Sealed the 26th May 1868, and dated the 28th November 1867.
PROVISIONAL SPECIFICATION left by the said William Cotton at the
Office of the Commissioners of Patents, with his Petition, on the
28th November 1867.
I, WILLIAM COTTON, of Hebden Bridge, in the County of York, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR CUTTING WOOLLEN AND COTTON CORDUROY OR OTHER SIMILAR
FABRICS," to be as follows:-
This Invention consists, firstly, in constructing, combining, and arranging
machinery or apparatus for cutting such fabrics, so that while continuous
motion is given to the fabric in passing through the machine in the usual
manner, reciprocatory motion is given to the knives employed for cutting the
said fabrics. This reciprocatory motion is effected by having the stock or
rest to which the knives are fixed capable of sliding in suitable slides or slots
formed in the framing, motion being given thereto by cranks and connecting

page_text: rods, eccentrics and rods, or any other means of producing reciprocatory
motion to the said knives.
rods, eccentrics and rods, or any other means of producing reciprocatory
motion to the said knives.
Secondly, in having the guides to the knives made round instead of flat,
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Cotton in the Great Seal Patent Office on the
28th May 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
COTTON, of Hebden Bridge, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of November, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Cotton, Her special licence that I, the said William
Cotton, my executors, administrators, and assigns, or such others as I, the
said William Cotton, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all tinies 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 FOR CUTTING WOOLLEN AND COTTON CORDUROY OR OTHER
SIMILAR FABRICS," upon the condition (amongst others) that I, the said
William Cotton, 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 Cotton, 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 thereof and accompanying Sheet of Drawings (that is to say) :-
:-
This Invention consists, firstly, in constructing, combining, and arranging
machinery or apparatus for cutting such fabrics, so that while continuous
motion is given to the fabric in passing through the machine in the usual
manner reciprocatory motion is given to the knives employed for cutting the

page_text: said fabrics. This reciprocatory motion is effected by having the stock or
rest to which the knives are fixed capable of sliding in suitable slides or
slots formed in the framing, motion being given thereto by cranks and
connecting rods, eccentrics and rods, or any other means of producing
reciprocatory motion to the said knives.
Secondly, in having the guides to the knives made round instead of flat,
Secondly, in having the guides to the knives made round instead of flat,
and to project at least one inch beyond the points of the knives.
DESCRIPTION OF THE DRAWINGS.
In order that this Invention may be clearly understood, I herein give
reference to an accompanying Sheet of Drawings of a machine constructed
in accordance therewith.
Fig. 1 represents a side elevation, and Fig. 2 a section of the same.
A is a card covered roller receiving rotary motion by gearing; B, cone
pullies, and straps C and D from the main driving pulley E, which may be
driven or turned by either hand or power; G are a series of cutting knives
which are mounted on pins 9 fixed in the stock or cross rail H at suitable
distances apart. This rail rests on bearings I, which are capable of sliding
on the bars J supported on brackets K fixed to the frame of the machine;
L are rods connecting these bearings with cranks formed or fixed on each
end of a shaft M, which receives rotary motion by means of a cone pulley N
and strap N¹ from another cone pulley N³, fixed on the same shaft as the
pulley D is fixed on. These cranks on the shaft M when in motion produce
the required reciprocatory motion to the knives. The fabric to be cut is
passed over and under a series of stretching bars or rails P, one or more of
which may be provided with an adjusting screw, as Q, for regulating the
amount of tension or drag thereon, and the fabric passing thence is conducted
over another bar or bed R and a rail S to the card roller A, which draws or
pulls the said fabric forward while the knives operate to cut open the pile.
The bar R and rail S are adjustable so as to enable the fabric and the knives
to be set suitably to each other for the proper cutting of the fabric.
Fig. 3 are full sized Drawings of a knife and its guide, shewing the form
thereof with its point round, and projecting at least one inch beyond the point
of the knife.
Having thus described the nature of this my said Invention, and shewn by
the accompanying Sheet of Drawings how the same is to be or may be
performed or carried into practical operation, I would have it understood that
I do not confine myself to the precise details of construction, combination,
or arrangement of the machinery as herein set forth, as various modifications

page_text: may be made therein; but what I claim as the essential feature of my
Invention is,-
Firstly. The giving or producing reciprocatory motion to the cutting knives
while the fabric to be cut has continuous motion.
Secondly. Having the knife guide points round, and to project at least one
inch beyond the points of the knives.
In witness whereof, I, the said William Cotton, have hereunto set my
hand and seal, this Twenty-sixth day of May, One thousand eight
hundred and sixty-eight.
WILLIAM COTTON. (L.S.)
