IMPROVEMENTS IN OR CONNECTED WITH THE MANUFACTURE OR ORNAMENTATION OF LENO. MUSLIN, DAMASK, AND TAPESTRY GOODS, AND PROVISIONAL SPECIFICATION
Year: 1880

page_text: LETTERS PATENT to Alexander Morton, of the Firm of Alexander Morton and
Company, of Darvel, in the County of Ayr, North Britain, Manufacturers, for
an Invention of "IMPROVEMENTS IN OR CONNECTED WITH THE MANUFACTURE
OR ORNAMENTATION OF LENO. MUSLIN, DAMASK, AND TAPESTRY GOODS, AND
PROVISIONAL SPECIFICATION left by the said Alexander Morton at the
Office of the Commissioners of Patents on the 17th August 1880.

CONNECTED WITH THE MANUFACTURE OR ORNAMENTATION OF LENO, MUSLIN,
DAMASK, AND TAPESTRY GOODS, AND MEANS WHEREBY SUCH IMPROVEMENTS ARE
EFFECTED."

The said Invention has for its object to so adapt the mechanism or means
employed in the manufacture of leno, muslin, damask, and tapestry goods, that
cards made from lace designs may be employed in the manufacture of such goods
for the production of patterns thereon, corresponding to the said lace patterns.
In carrying the Invention into effect in respect of leno and muslin goods, in
order to enable lace cards to be used for the production of patterns thereon, I tie
two cords of the harness to each wire of the jacquard, so that each wire lifts two
threads of the leno or muslin ground, and thus after the roving or pattern threads
are thrown through, they are confined by at least two threads of the ground, and
the pattern is kept in due proportion of length and width.
In carrying the Invention into effect in respect of damask and tapestry goods, in
order to enable lace cards to be used for the production of patterns thereon,
two warp threads are caused to be lifted by each wire of the jacquard in order
to keep the pattern of the proper relative width and length. In order that
the cloth may be formed where the pattern is of considerable extent, that is, to
prevent long lengths of unwoven weft and warp threads, I provide a set of cards
placed beneath the lace cards, and so arranged relatively therewith that this second
set of cards prevents the raising of the harness at particular parts, and so causes
the warp and weft threads to be woven together at these particular parts.

the said Alexander Morton in the Great Seal Patent Office on the 15th
February 1881.
ALEXANDER MORTON, of the Firm of Alexander Morton and Company, of Darvel,
in the County of Ayr, North Britain, Manufacturers. "IMPROVEMENTS IN OR
CONNECTED WITH THE MANUFACTURE OR ORNAMENTATION OF LENO, MUSLIN,
DAMASK, AND TAPESTRY. GOODS, AND MEANS WHEREBY SUCH IMPROVEMENTS ARE
EFFECTED."
My said Invention has for its object to so adapt the mechanism or means
employed in tho manufacture of leno, muslin, damask, and tapestry goods, that
cards made from lace designs, or which have been made for use in lace machines
may be employed in the manufacture of such goods, for the production of patterns
thereon corresponding to the said lace patterns. In carrying my invention into
effect in respect of leno and muslin goods, in order to enable lace cards to be used
to operate upon the jacquard apparatus of the looms or apparatus in which these
goods are manufactured, I connect or tie two adjacent cords of the harness to each
wire of the jacquard apparatus, so that each wire lifts two cords, and consequently
two warp threads of the leno or muslin ground, and thus, after the roving or
pattern threads are thrown through, they are confined by at least two threads of
the ground, and the pattern is kept in due proportion of length and width.
In carrying my Invention into effect in respect of damask and tapestry goods, in
order to enable lace cards to be used for the production of patterns thereon, two
warp threads are caused to be lifted by the means, as hereinbefore described, in
order to keep the pattern of the proper relative width and length. In order that
the cloth may be formed where the pattern is of considerable extent, that is, to
prevent long lengths of unwoven weft and warp threads, I provide a second, set of
cards placed on the jacquard cylinder or card carrier, or so as to come beneath the
lace cards, when they are presented in position to actuate the jacquard wires;
perforated and unperforated parts of this said second set of cards being so arranged
relatively with perforations in the lace cards, that at intervals unperforated parts
of the second set of cards will be presented beneath the lace cards, and prevent the
raising of the harness cords at particular parts (where the openings in the lace
cards would otherwise allow them to be raised), and so cause the threads of the
fabric to be tied down or interwoven at these particular parts. In the accom-
panying Drawings I have shewn a portion of a jacquard cylinder or card carrier
with two cards, one beneath the other, according to iny Invention. The lace cards
are shewn at a. Underneath these cards are other cards b, which may be fixed
upon the four sides of the jacquard card carrier, as shewn. Figure 1 is a plan, and
Figure 2 is an end elevation of a portion of the jacquard cylinder or card carrier
with the two cards, the lace card a being uppermost, and the cards b undermost;
Figure 3 is a plan of a corresponding portion of a card b. The holes in the cards
a and b are coincident with the exception of rows as at c in the cards b extending
from end to end of the cards, at which rows the said cards b are unperforated, so
that when these unperforated parts of the cards b are beneath perforations which
may occur in these lines in the lace cards a, the jacquard wires at these perforations
are prevented from causing the lifting of the warp at these parts, with the effect
before stated of causing the weaving or tying down of the threads of the fabric at
these parts. In Figure 1 the holes of the card a which are closed by the card b
beneath are marked with a cross. The lines c of the cards b without perforations
may be at regular or irregular intervals, for although in the Drawing the
unperforated lines c are shewn at each fourth line of the card b, I do not limit

page_text: myself to this or any other particular number of lines of holes which intervene
between each unperforated line c.
Having now described and particularly ascertained the nature of my said
Invention, and the system, mode, or manner in or under which the same is or may
be used or practically carried into effect, I would observe in conclusion that what I
consider to be novel and original, and therefore claim as the Invention secured to
me by the hereinbefore in part recited Letters Patent is,-
First. The combination or adaptation with, or in, or to looms or apparatus for
the manufacture or ornamentation of leno, muslin, damask, and tapestry goods of
the means whereby cards which are made from lace designs, or for use in lace
making machines are rendered capable of employment in the said looms or
apparatus, as hereinbefore described.
Second. The combination of two sets of cards in the jacquard apparatus of looms
or apparatus for the manufacture of damask and tapestry goods, one of the said
sets of cards being cards which are made from lace designs, or for use in lace.
making machines, and the other being a set of cards with unperforated lines
therein, as and for the purpose described with reference to the accompanying
drawings.
In witness whereof, I, the said Alexander Morton, have hereunto set my
hand and seal, this Twelfth day of February, in the year of our Lord
One thousand eight hundred and eighty one.
ALEXANDER MORTON. (L.S.)
