Cartmell Braithwaite, of Kendal, in the County of Westmorland,
Carpet Manufacturer, for the Invention of "THE MANUFACTURE Of
IMPROVED KENDAL TAPESTRY CARPETING, WITH ANY NUMBER OF WEFT

Sealed the 4th July 1873, and dated the 29th January 1873.
PROVISIONAL SECIFICATION left by the said Robert Todd and John
Cartmell Braithwaite at the Office of the Commissioners of Patents,
with their Petition, on the 29th January 1873.
We, ROBERT TODD, of Kendal, Mechanic, and JOHN CARTMELL
BRAITHWAITE, of Kendal, in the County of Westmorland, Carpet Manu-
facturer, do hereby declare the nature of the said Invention for "THE

page_text: MANUFACTURE OF IMPROVED KENDAL TAPESTRY CARPETING, WITH ANY NUMBER OF
WEPT SHOOTS OF WOOLLEN, LINEN, OR COTTON," to be as follows:-
We use the same warp of linen, cotton, woollen, or worsted as we now
usc. Wo use the same linen, cotton, or woollen weft as is now used,
and by altering the manner of working the loom and the jacquard
working therewith we are able to show on the surface of the carpet not
only two colours but three, four, fivo, or as many as we wish, and to
dispose and arrange them in harmonious patterns, cither concealing the
yarn when it is not shown on the surface, by burying it under the yarn for
the time being shown on the surface, or so disposing of it as to produce
a pattern on the under part or back of the carpet; and to accomplish this
we take a loom with a jacquard working therein, such as are used in the
manufacture of carpets whether Kidderminster carpets, or Kendal
tapestry carpets; which loom consists of ordinary loom standards and
bearings supporting a jacquard apparatus with two draught boards,
planes, and harness worked in the ordinary manner by two treadles, and
having two warp beams set in bearings at the back of the loom, onc
behind the other, from which the warps are allowed to pass through the
harness to the front of the loom as required for weaving the carpet.
The cloth when woven is wound on to a beam placed under the warp
beams at tho back of the loom.
The improvements for which we now petition protection are as follows,
viz:-The arrangement and use of one draught board in the jacquard
apparatus in place of two, and of only one treadle instead of two. Tho
barrel or cylinder is made to turn once for every shoot of weft thrown
in, and a set of heald gears through which the warps are mado to
pass is so arranged as to take the place of two of the planes formerly
used, and is worked from the jacquard apparatus by needles placed
therein, which needles are in their turn worked by the cards as they pass
over the barrel or cylinder.
By these improvements in the machinery and appliances therewith
connected we are enabled to use three, four, five, or more wefting shoots
of yarn of different colours or the same colour, and so to dispose of them
as to form a pattern or patterns, as herein-before described, raising and
sustaining any or all of them side by sido at one and the same time along
any given straight line that may be drawn across the cloth from selvedge
to solvedge, where it has formerly been possible in either Kidderminster,

page_text: Kendal tapestry, or other similar carpeting to raise only two wefting
shoots along any such line, as described above. The special advantage
of these improvements being that they enable us to introduce any
number of wefting shoots without any addition to the warps ordinarily
used in the manufacture of Kendal tapestry.
