IMPROVED MEANS OF TAKING UP THE THREADS IN WARP MACHINES, ALSO IN THE CONSTRUCTION OF POINTS FOR SUCH PURPOSE
Year: 1871

page_text: LETTERS PATENT to Amos Tatham and Herbert Tatham, of the
Belper Street Works, Ilkeston, in the County of Derby, Manu-
facturers, for the Invention of "IMPROVED MEANS OF TAKING UP THE
THREADS IN WARP MACHINES, ALSO IN THE CONSTRUCTION OF POINTS FOR
SUCH PURPOSE."
Sealed the 21st July 1871, and dated the 27th January 1871.
PROVISIONAL SPECIFICATION left by the said Amos Tatham and
Herbert Tatham at the Office of the Commissioners of Patents,
with their Petition, on the 27th January 1871.
We, AMOS TATHAM and HERBERT TATHAM, of the Belper Street
Works, Ilkeston, in the County of Derby, Manufacturers, do hereby
declare the nature of the said Invention for "IMPROVED MEANS OF TAKING
UP THE THREADS IN WARP MACHINES, ALSO IN THE CONSTRUCTION OF POINTS FOR
SUCH PURPOSE," to be as follows :—
Our Invention relates to the construction and application of points for
taking up the threads in
warp machines. Two points are used to
each needle, and are employed for the purpose of taking up the bobbin

page_text: threads to the needles after these threads have been selected by any
suitable jacquard apparatus. The point bar is passed up to and between
the needles by the mechanism, and whilst in this position there are two
points between every needle. These points may be made of any suitable
shape. The point bar is passed up to and between the needles by
means of levers attached to the point bar. The motion to these levers
is communicated by means of cams fixed on the back shaft of the
machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Amos Tatham and Herbert Tatham in the Great
Seal Patent Office on the 27th July 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, AMOS
TATHAM and HERBERT TATHAM, of the Belper Street Works, Ilkeston,
in the County of Derby, Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of January, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Amos Tatham and Herbert Tatham,
Her special licence that we, the said Amos Tatham and Herbert Tatham,
our executors, administrators, and assigns, or such others as we, the said
Amos Tatham and Herbert Tatham, our 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 "IMPROVED MEANS OF TAKING UP THE THREADS IN
WARP MACHINES, ALSO IN THE CONSTRUCTION OF POINTS FOR SUCH PURPOSE," upon
the condition (amongst others) that we, the said Amos Tatham and
Herbert Tatham, or one of us, our executors or administrators, by an
instrument in writing under our, or one of our, 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.

page_text: NOW KNOW YE, that we, the said Amos Tatham, and Herbert Tatham,
do hereby declare the nature of our 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, reference being had to the
Drawings hereunto annexed, that is to say :-
Our Invention relates to the construction and application of points
for taking up the threads in warp machines. Two points are used
to each needle, and are employed for the purpose of taking up the
bobbin threads to the needles after these threads have been selected by
any suitable jacquard apparatus. The point bar is passed up to and
between the needles by the mechanism, and whilst in this position there
are two points between every needle. These points may be made of any
suitable shape. The point bar is passed up to and between the needles
by means of levers attached to the point bar. The motion to these lévers
is communicated by means of cams fixed on the back shaft of the
machine.
The Invention will be understood by reference to the accompanying
Drawings and the following detailed description.
Figure 1 is a view of the position the points and the guides occupy
before the pillar thread is laid upon the thick thread under the needle,
a being the point, the pillar thread guide, and c the thick thread
guide. The thick thread which is passed through the eye of the guide c
is carried under the needle by the points a, which rise in their backward
movement into the position shown in dotted lines, taking the thick
thread and pushing it under the needle. The thread which is passed
through the cye of the guide 6 is conveyed to the needle d and laid
upon it. When the points are in the position shown in the dotted lines
the pillar guide is raised above the needle to lay the thread on it.
A detached view of the points on a larger scale is represented in
Figure 2, which points are so arranged in their leads e that a space is
left of rather a larger width between every pair to allow of the needles
coming between them in those spaces. This placing of the points in
pairs as just described is an essential feature in our Invention, as it
prevents the roughness in the fabric by the threads rubbing against
each other as is the case in other machines in which one point is used
to each needle. There is no special form or shape in which our points
need be made, but we prefer to make them of flat plate with the back
edge rounded or tapered off to a point, as shown.

page_text: And having now described the nature of our said Invention, and in
what manner the same is to be performed, we declare that we claim, the
special means of taking up the threads in warp machines as herein-before
described. We also claim the employment of two points between cach
needle of warp machines, as described and shown.
In witness whereof, I, the said Herbert Tatham, for myself and
on behalf of the said Amos Tatham, have hereunto set my hand
and seal, this Twenty-seventh day of July One thousand eight
hundred and seventy-one.
