IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1874

page_text: LETTERS PATENT to Thomas Longworth and Francis Lloyd Jones,
both of Blackburn, in the County of Lancaster, Cotton Manufac-
turers, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said Thomas Longworth and
Francis Lloyd Jones at the Office of the Commissioners of Patents,
with their Petition, on the 2nd December 1874.
We, THOMAS LONGWORTH and FRANCIS LLOYD JONES, both of Black-
burn, in the County of Lancaster, Cotton Manufacturers, do hereby
declare the nature of the said Invention for " IMPROVEMENTS IN LOOMS FOR
WEAVING," to be as follows:-
This Invention relates to further improvements in the construction,
combination, and arrangement of apparatus employed for producing
figured or ornamental borders on pieces or fabrics as woven, and for
which object Letters Patent were granted to us dated the 25th day of
January 1873, No. 298.

page_text: According to this our present Invention we employ a shaft extending
across the loom near the top rail, and having rotary motion com-
municated thereto by means of a peg wheel, on which shaft is a barrel,
over which works a series of lags forming an endless chain or web. In
the several lags are pin holes and pins, which as the barrel revolves
brings the pins in contact with the outer arms of the border shedding
levers mounted on short shafts carried by brackets extending from a
cross rail, the other end of the said levers being provided with counter-
balanced or weighted ends. There is a like series of such levers mounted
on a short shaft, as described, at each side of the loom, and one or both
series of levers may readily be moved and adjusted on their respective
shafts as the width of figured border or width of the piece or fabric being
woven may require.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Longworth and Francis Lloyd Jones in 1
the Great Seal Patent Office on the 2nd June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
LONGWORTH and FRANCIS LLOYD JONES, both of Blackburn, in the
County of Lancaster, Cotton Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of December, 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 successors, give and
grant unto us, the said Thomas Longworth and Francis Lloyd Jones, Her
special licence that we, the said Thomas Longworth and Francis Lloyd :
Jones, our executors, administrators, and assigns, or such others as we, the
said Thomas Longworth. and Francis Lloyd Jones, our executors, admini-
strators, and assigns, should at any time agree with, and no others,
from time to time and at all times thercafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, a
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN LOOMS FOR
WEAVING," upon the condition (amongst others) that we, the said
Thomas Longworth and Francis Lloyd Jones, our executors or admini-

page_text: strators, by an instrument in writing under 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
3 Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Longworth and Francis
Lloyd Jones, 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, reference being had
to the accompanying Drawings and to the figures and letters marked
thereon, that is to say :—
This Invention relates to further improvements in the construction,
combination, and arrangement of apparatus employed for producing
figured or ornamental borders on pieces or fabrics as woven, and for
which object Letters Patent were granted to us, dated the 25th day of
January 1873, No. 298.
According to this our present Invention we employ a shaft extending
across the loom near the top rail, and having rotary motion commu-
nicated thereto by means of a peg wheel, on which shaft is a barrel,
over which works a series of lags forming an endless chain or web.
In the several lags are pins, which as the barrel revolves brings the pins
in contact with the outer arms of the border shedding levers mounted on
short shafts carried by brackets extending from a cross rail, the other
ends of the said levers being provided with counterbalanced or weighted
ends. There is a like series of such lovers mounted on a short shaft (as
described above) at each side of the loom, and one or both series of levers
may readily be moved and adjusted on their respective shafts as the
width of figured border or width of the piece or fabric being woven may
require.
Such being the nature and object of this our said Invention we will
now proceed to describe the same in detail, and in order that the same.
may be fully understood we have hereunto annexed a Sheet of Drawings
illustrative thereof, and have marked the same with figures and letters
of reference, the same letter referring to the same part in the several
views or figures.

page_text: Figure 1 is an end elevation, shewing levers and peg lags in position;
Fig. 2 is a back elevation; Fig. 3 is a plan view.
At A is a shaft extending across the loom; rotary motion is given
thereto by means of the peg wheel B. At C is the barrel, over which
works the series of lags D, forming an endless chain or web. In the
several lags D are pins E, which are inserted in the holes in the lags, so
that as the lags are passed by the rotation of the barrel under the shedding
levers F the pins will act upon and raise the said shedding levers
according to the pattern or figure required to be woven. These levers
re, as shewn, mounted on a short shaft G, carried by the bracket H,
which in turn is supported from the cross rail J, to which it is bolted.
The levers F are provided with counterbalanced ends F', so reducing the
wear and tear of the lifting pins to a minimum.
Having thus fully described the nature and particulars of this our said
Invention we would have it distinctly understood that we lay no claim
to any of the parts herein referred to considered separately from the use
of the weighted levers F when operated by and in combination with the
pins and lags in the manner and for the purpose described, and as herein
illustrated by Drawings; we make no claim to any of them.
In witness whereof, we, the said Thomas Longworth and Francis:
Lloyd Jones, have hereunto set our hands and seals, this Twenty-
ninth day of May, in the year of our Lord One thousand eight
hundred and seventy-five.
