IMPROVEMENTS IN LOOMS
Year: 1874

page_text: LETTERS PATENT to Josepli. Pickard, of Bradford, in the County o
York, Mechanic, for the Invention of "IMPROVEMENTS IN LOOMS,"
Sealed the 23rd April 1875, and dated the 26th October 1874.
PROVISIONAL SPECIFICATION left by the said Joseph Pickard at
the Office of the Commissioners of Patents, with his Petition, on
the 26th October 1874.
I, JOSEPH PICKARD, of Bradford, in the County of York, Mechanic,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
Looms," to be as follows:-
This Invention relates to certain improvements in the method of and
apparatus for weaving figured fabrics with jacquard looms. I cause the
card cylinder to reverse one or more cards as required when the weft is
broken or all woven from off the spool, instead of the ordinary method of
reversing them by hand, thus saving a great amount of time, and giving
a more uniform piece, with less care and attention on the part of the
weaver. I accomplish this in the following manner :-A cord, chain, or
other suitable connection is fixed to the ordinary weft fork, which chain

page_text: or cord passes over a small grooved pulley secured to framework of loom.
The other end of chain or cord is attached to a lever centred on a stud
and joint secured to bottom framework of loom. To the other end of the
said lever I fix a rod, cord, or chain, which is attached to the ordinary
catch of a jacquard engine. When the weft is broken the fork to which
is attached chain or cord is drawn back in the usual way, and lifts up
one end of lever; the other end passes down and draws rod, which
lifts up catch of jacquard engine, thus causing cards to reverse, as
required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Pickard in the Great Seal Patent Office on
the 26th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
PICKARD, of Bradford, in the County of York, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of October, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Joseph Pickard, Her special
licence that I, the said Joseph Pickard, my executors, administrators,
and assigns, or such others as I, the said Joseph Pickard, 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
thercin expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ircland, the
Channel Islands, and Isle of Man, an Invention for " IMPROVEMENTS
IN Looms," upon the condition (amongst others) that I, the said
Joseph Pickard, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and scals, 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 Scal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Pickard, do hereby declare
the nature of my said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the
following statement :-
I
This Invention relates to certain improvements in the method of and
apparatus for weaving figured fabrics with jacquard looms. I cause the
5 card cylinder to reverse one or more cards as required when the weft is
broken or all woven from off the spool, instead of the ordinary method of
reversing them by hand, thus saving a great amount of time, and weaving
a more uniform piece with less care and attention from the weaver.
accomplish this in the following manner:-To the front or breast beam
Obf the common loom I attach a bracket, on which is centred a compound
lever, or what is commonly known as an L leg lever, one end of which
rests against tlie ordinary fork lever. To the other end I attach a rod,
which is coupled to the end of another lever of the first order, and
centred in á bracket fixed to the bottom rail of the loom. To the other
5 end of the said lever I attach a rod, which is coupled to one end of
another lever of the first order, and centred on a stud secured to the top
rail of loom. To the other end of the last-named lever I attach a chain or
cord, which is also secured to the bottom catch lever of the ordinary
jacquard.
.
:
I will now proceed to describe the accompanying Drawings, in which
like parts are indicated by like letters.and figures.
:
All parts of the ordinary loom not necessary for the elucidation of
these improvements are omitted in the Drawings, being the same in any
ordinary loom to which my improvements may be applied.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an end elevation of an ordinary loom with my improved
apparatus applied; Figure 2 is a front view of the same..
A, A, A, is the ordinary cast-iron framework of a loom; B is the front
or breast bcam secured to framework A; B' is the ordinary weft fork
lever; C is a cast bracket secured to breast beam; D is a compound'
lever or L leg lever, and centred on bracket C by a stud d; E, a rod
attached to lever D at D', and lever F at F', which said lever is centred
on stud secured to bracket G and bottom rail of loom in the ordinary
way; H is another rod that connects lever F at Fº to lever J at J',
which is centred on a stud secured to top rail of loom; K is a weight
fixed on J; L is the ordinary wood gauntry for supporting jacquard;

page_text: M, M, is the ordinary framework of jacquard secured to L in the usual
way; N is the bottom catch lever centred on a stud fixed to frame-
work M at N'. On N Tattach a chain or cord C', which is also attached
to lever J at Jª; the top catch lever O is attached to framework in the
usual way; P is the ordinary card cylinder suspended in rocking arm Q;
R is a rod resting on lever N, and has free action through holes in M;
S is a weight suspended from end of lever N at Nº.
usual way; P is the ordinary card cylinder suspended in rocking arm Q;
R is a rod resting on lever N, and has free action through holes in M;
S is a weight suspended from end of lever N at N2.
ACTION OF Apparatus.
The motion is transmitted to the loom and jacquard in the usual way,
and the loom fitted with the ordinary weft fork and lever. It will be 1
easily perceived that when the weft is broken or all woven from off the
bobbin or spool that the weft lever B will press against compound
lever D, and partly revolve the same on stud d, lifting up D¹, rod E, and
end of lever F at F¹. The other end of lever at F, which is attached by
rod H to J' will descend, and partly revolve on stud fixed in top rail, 1
thus slackening the tension of cord or chain C³, when end of lever
at N¹ will be lifted up by means of weight S at the other end of lever N
at N into gear with cylinder P, at the same time lifting lever O out of
gear by means of rod R, when cylinder P will be reversed one or more
cards as required by the setting of the same before the loom is stopped.
In witness whereof I, the said Joseph Pickard, have hereunto set
my hand and seal, this Twenty-third day of April, in the year of
our Lord One thousand cight hundred and seventy-five.
Signed, sealed, and delivered, by the
above-named Joseph Pickard, in
the presence of
JOHN WAUGH,
Engineer and Patent Agent,
Bradford.
