IMPROVEMENTS IN JACQUARD " APPARATUS
Year: 1870

page_text: LETTERS PATENT to John Morris, of Belfast, in the County of
Antrim, Ireland, for the Invention of "IMPROVEMENTS IN JACQUARD
"
APPARATUS.”
Scaled the 23rd August 1870, and dated the 14th March 1870.
PROVISIONAL SPECIFICATION left by the said John Morris at the
Office of the Commissioners of Patents, with his Petition, on the
14th March 1870.
I, JOHN MORRIS, of Belfast, in the County of Antrim, Ireland, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
JACQUARD APPARATUS," to be as follows:-
My Invention has reference to the hooks employed in jacquard
apparatus. These hooks have hitherto been formed as seen at Figuro 1
of the annexed Drawings, and the heads being single have not allowed
of using two cylinders, one on each side of the machine unless two sets
of needles were put in where with my improved hooks I have only one
set.

page_text: My Invention consists in making double-headed hooks substantially
of the form represented in Figure 2,'whereby I can employ two cylinders,
one to weave the centre and one to weave the border, so that it is not
necessary to change the cards, for the cylinders can be put in motion
sooner than the cards can be changed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Morris in the Great Seal Patent Office on the
14th September 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MORRIS, of Belfast, in the County of Antrim, Ireland, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of March, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Morris, Her special licence,
that I, the said John Morris, my executors, administrators, and
assigns, or such others as I, the said John Morris, 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 JACQUARD
APPARATUS," upon the condition (amongst others) that I, the said John
Morris, 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 John Morris, do hereby declare
the nature of my said Invention, and in what manner the same is to be
nanformad

page_text: The operation of the apparatus is as follows:-Supposing it is desired
to work the cylinder a this cylinder is turned so that its cards are
brought against the needles so as to act on them, while the cylinder a¹ is
turned so that its cards are down and so that an open face of this
cylinder comes opposite the needles. The knives e, e¹, e³, are moved into
the position shown in the Figures so that the two knives e, e¹, come
respectively under the heads of the two rows of hooks b, b, while the
third knife e³ is idle. When the frame d is raised together with the
knives the hooks b, b, catch upon the two working knives and are lifted
or left according to the cutting of the cards in the cylinder a. During
the upward movement of the frame d the bent levers 7, 9, have moved
the cylinders into the position seen in Figure 4 clear of the needles c.
In the downward movement of the frame d the cylinders are returned to
the needles so that the cards of the cylinder a again act on the needles
and move some of the hooks b, b, ready for the next upward movement
of the frame d. When it is required to change and work the cylinder a¹
the frame d is raised, the cylinder a is turned so that an open face comes
opposite the needles and the cylinder a¹ is turned to bring its cards
opposite the needles so as to act on them, the frame d is then lowered,
and the knives are thrown over into the reverse position (shown in
dotted lines in Figure 3) to bring the knives c¹, e³, under the two rows
of hooks while the knife e will be idle. The apparatus is now ready to
be worked with the cylinder a¹.
From the foregoing description and the Drawings it will be readily
seen how with my double-headed hooks I can employ two cylinders, one
ou cach side of the machine, with only one set of needles, and how
readily the change from one cylinder to another can be effected. The
mechanism or motion for working the cylinders may be varied, but
that shown in the Drawings and herein-before described is that which
I think best under ordinary circumstances.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim as my
"Improvements in Jacquard Apparatus,"-
First. The construction and employment of double-headed hooks as
and for the purpose herein-before described and represented in the
accompanying Drawings.
Second. In combination with the double-headed hooks I claim the
arrangement consisting of two cylinders, one set of needles, and other

My Invention has reference to the hooks employed in jacquard
apparatus. These hooks have hitherto been formed as seen at Figure 1
of the annexed Drawings, and the heads being single have not allowed
of using two cylinders, one on each side of the machine, unless two
sets of needles were put in where with my improved hooks I have only
one set.
My Invention consists in making double-headed hooks substantially
of the form represented in Figure 2, whereby I can employ two cylinders,
one to weave the centre and one to weave the border, so that it is not
necessary to change the cards, for the cylinders can be put in motion
sooner than the cards can be changed.
The manner in which my double-headed hooks may be applied will bo
understood on reference to Figures 3 to 7 which represent a jacquard
apparatus fitted with my hooks and having two cylinders and one set of
needles. Figure 3 is an elevation partly in section with the hooks
down; Figure 4 is a similar view with some of the hooks lifted;
Figure 5 is an elevation taken at right angles to Figures 3 and 4;
Figure 6 is an elevation of the opposite side to that shown in Figures 3
and 4; Figure 7 is a plan.
a, a¹, are the two cylinders one on each side of the machine; b, b, are
my double-headed hooks; and c, c, are the needles which are provided
with springs at both ends as shown; d is a frame to which an up-and-
down motion is imparted by any ordinary mechanism; e, e', e, are three
knives resting at their ends in the frame d and free to be turned to one
side or the other so as to incline from the cylinder which for the time
being is at work; f,f, are two frames in which the two cylinders a, a¹,
are respectively carried. These frames are connected by bent levers g, g,
to studs h, h, on a wheel i to which an alternating partial rotary motion
is imparted through the intermediation of a rod j by the up-and-down
movements of the frame d so that when the frame d is raised the frames
ff, are moved outwards as seen in Figure 4, while when the frame dis
lowered the frames f,f, are in a vertical position, as in Figure 3, the
cylinders a and a¹ being then so placed that the cylinder which for the
time being is at work has acted upon the needles c, c, according to the
cutting of the cards in that cylinder.

In witness whereof, I, the said John Morris, have hereunto set
my hand and seal, this Tenth day of September One thousand
eight hundred and seventy.
