IMPROVEMENTS IN THE MANUFACTURE OF CERTAIN DESCRIPTIONS OF FABRICS, AND IN LOOMS FOR WEAVING THE SAME AND OTHER FABRICS
Year: 1870

page_text: LETTERS PATENT to Edward Lord, of Todmorden, in the County of
York, Machine Maker, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF CERTAIN DESCRIPTIONS OF FABRICS, AND IN LOOMS FOR
WEAVING THE SAME AND OTHER FABRICS."
Sealed the 21st February 1871, and dated the 13th September 1870.
PROVISIONAL SPECIFICATION left by the said Edward Lord at the
Office of the Commissioners of Patents, with his Petition, on the
13th September 1870.
I, EDWARD LORD, of Todmorden, in the County of York, Machine
Maker, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF CERTAIN DESCRIPTIONS OF FABRICS, AND IN
LOOMS FOR WEAVING THE SAME AND OTHER FABRICS," to be as follows:-
My Invention consists in so constructing the elevators and depressers
of plate or segment tappets that they may act equally on either of two
sets of treadles which are brought alternately into position for communi
cating a positive up-and-down motion to the jacks or other instruments.
for working the healds.

page_text: The object of applying two sets of treadles to one set of tappets is to
enable different descriptions of fabrics to be woven by merely discon-
necting one set of treadles and bringing the others into their working
position, and vice versa; or both sets of treadles may be worked at the
same time so as to produce a new description of striped fabric being
partly of the kind known as "Lasting," and partly of the kind known as
"Russell."
By means of these improvements various descriptions of twilled
fabrics can be woven, which heretofore could only be produced in looms
provided with a shedding motion to draw down the lower portion of the
shed-and-weights to raise the healds.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Lord in the Great Seal Patent Office on
the 8th March 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
LORD, of Todmorden, in the County of York, Machine Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of September, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Lord, Her special licence that
I, the said Edward Lord, my executors, administrators, and assigns, or
such others as I, the said Edward Lord, 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 THE MANUFacture
OF CERTAIN DESCRIPTIONS OF FABRICS, AND IN LOOMS FOR WEAVING THE SAME
AND OTHER FABRICS," upon the condition (amongst others) that I, the
said Edward Lord, my executors or administrators, by an instrument
in writing under my, or their, or one or their hands and seals, should

page_text: 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 Edward Lord, 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 (that is to say) :-

My Invention consists, first, in the manufacture of certain descriptions
of striped woven fabrics being partly of the kind known as Lasting,"
and partly of the kind known as Russell," and secondly, in certain
improvements in the construction and arrangement of looms for weaving
the compound fabrics above described or other fabrics.
And in order that my Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Fig. 1 is an end view, and Fig. 2 a front view of a loom to which my
improvements are applied. a is the crank shaft; b, the tappet shaft.;
c the tappets, one of which is shewn half size in Fig. 3; d, d', are two
sets of treadles, the treadles & working above the centre of the tappets as
usual, and the treadles d', which are now shewn out of gear working
when in gear below the said centre. The treadles d are connected by
the ordinary cords and straps to the top jacks e, and bottom jacks f,
these jacks are very similar to those in ordinary use, but instead of
suspending each heald to one jack as usual, I employ supplementary
jacks above and below, as shewn at e¹ and f¹, the jacks e and ƒ being
connected to the supplementary jacks e¹ and f¹ by the levers and links
shewn in Fig. 2. The healds g are united to the upper and lower jacks
by cords and straps, and as the treadles are raised and lowered by
the tappets a positive up-and-down motion is imparted to the healds.
The peculiar mode of connecting the healds to the jacks and supple-
mentary jacks keeps them horizontal in their up-and-down motion.
On referring to Fig. 3 it will be seen that the elevators and depressers
on the tappet plates are so shaped that they may act equally well on
either of the two sets of treadles d or d³, and that the bowl of the
treadle is restrained between the beads of the tappet, so that the tappet
opens and closes the shed positively.

page_text: The Drawing represents the upper set of treadles in work, and the
other parts of the loom are constructed and arranged to weave the fabrics
known as "Lastings." When the lower set of treadles are brought into
the working position and the upper set is lifted out of gear, the loom
would be in order for weaving the fabrics known as "Russells," and when 5
both the sets of treadles are in work at the same time and the treadles
are united to the requisite number of jacks the loom would be ready to
weave the improved compound fabrics above described.
By means of these improvements various descriptions of twilled fabrics
can be woven which heretofore could only be produced in looms provided 1
with-a-shedding-motion_to_draw_down the lower portion of the shed and
weights to raise the healds.
My improvements increase the production of such fabrics and simplify
the construction of the looms.
Having thus stated the nature of my Invention and described 1
the manner of performing the same, I declare that I claim as my
Invention,-
First. The improved manufacture of striped woven fabrics being part
Lasting" and part "Russell," as described.
Secondly. The application of two sets of treadles to one-set of tappets 2
as shewn and described.
Thirdly. The improved mode of constructing the jacks and supple-
mentary jacks and connecting the healds to them when used in the
manner and for the purposes described.
Fourthly. The improved construction of tappets as shewn and 2
described.
In witness whereof, I, the said Edward Lord, have hereto set my
hand and seal, this Seventh day of March One thousand eight
hundred and seventy-one.
