Patterns upon Cut or Uncut Pile Fabrics.
We, EDWIN FIELD, of Skelmanthorpe, Yorkshire, Manufacturer and GEORGE
TUNNICLIFF, of the same place, Designer, do hereby declare the nature of our invention
for IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR PRODUCING PATTERNS
UPON CUT OR UNCUT PILE FABRIOS," to be as follows:-
Our invention consists in apparatus to be employed for the purpose of producing
patterns on either cut or uncut pile fabrics, and this we accomplish by simple and self-
acting mechanism.
In carrying out our invention we use the ordinary warp and beams for forming the
pile of the fabric, but in addition to this we employ a rectangular frame of about the
same length as the warp beam, which frame is provided with rods or bars running
longitudinally therein, the number of such rods or bars corresponding to the number
of healds employed to form the pattern or design.
The ends of the rods or bars are placed loosely in bearings, so that they can rise and
fall somo little distance for purposes hereinafter explained.
The rectangular frame is used in connection with the warp for forming the pattern,
such frame being placed at a position between the warp beam and the healds or
"harness." When the loom proceeds to weave, the required heald or healds for
forming the pattern are operated and the "shed "formed thereby. As the threads of
warp which are operated by the healds are under their respective rods in the frame,
it follows that when the pile wire is inserted, and the warp again operated will be
drawn tightly around the pile wire and that warp will be taken up equal to the depth
of the wire forming the pattern.
The threads of warp which are threaded through the unoperated healds having been
made slack by the partial rotation of the warp beam will be drawn tight and clear of
the shed by the weight of the rods or bars under which they pass, and when the figure
requires it such threads of warp will be taken up by the pile wire in the same manner
as previously explained.

page_text: The warp may be of any required colour and strength, and patterns may be made
on all kinds of fabrics where the pile is made from the warp-such as-seals, curls,
astracans, loops, plush, carpets, and rugs.
By the means above described we are enabled to weave figures or patterns on pile
cloths with warp from off one beam, which cannot be done in the present arrangement
as a considerable number of beams are required to form the pattern.
Instead of using rods or bars to weight the warp, a weight may be hung or
suspended from each thread of warp.
Our invention is equally applicable to either hand or power looms.

Improvements in the Method of and Apparatus for Producing
Patterns upon Cut or Uncut Pile Fabrics.
We EDWIN FIELD of Skelmanthorpe Yorkshire, Manufacturer, and GEORGE
TUNNICLIFF of the same place, Designer do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
Our invention consists in apparatus to be employed for the purpose of producing
patterns on either cut or uncut pile fabrics, and this we accomplish by simple and
self-acting mechanism.
In carrying out our invention we use the ordinary warp and beams for forming the
pile of the fabric, but in addition to this we employ a rectangular frame of about
the same length as the warp beam which frame is provided with rods or bars running
longitudinally therein, the number of such rods or bars corresponding to the number
of healds employed to form the pattern or design. The ends of the rods or bars are
placed loosely in bearings, so that they can rise and fall some little distance.
In order that our invention may be more fully understood we herein make reference
to the accompanying sheet of Drawings wherein Fig. 1 is sectional view of certain
parts of a loom showing the application of our improvements thereto.
A is the warp beam, B and C the healds, and D the cloth beam all arranged and
operated in the ordinary manner.
Our improvements are shown at E which is a rectangular frame of the same length
or nearly the same length as the warp beam, and which is supported in any suitable
manner. This frame is divided into a number of compartments a in each of which
compartments are placed bars or rods & running longitudinally therein and capable of
rising and falling some little distance for purposes hereinafter explained. It is only
necessary to place the same number of rods or bars 6 in the frame as there are healds
for forming the pattern.
The warp for forming the pattern is selected and divided in the ordinary manner
and according to the pattern to be woven, such divisions of the warp being then
threaded through their respective healds.
A rod or bar bis then placed over each of the said divisions of warp, and inserted
into the compartments a whereby the threads of warp threaded through each heald arc
passed under separate rods working in separate compartments.
The mode of operation is as follows
When the loom commences to weave the required heald or healds for forming the
pattern are operated and the "shed" formed thereby. The warp beam is then partially
rotated to give out warp necessary for forming the pattern such warp being taken up
by the depth of the "pile" wire that is placed under the said warp whereby the warp
that is threaded through the operated healds (represented at B) is elevated in loops
above the surface of the cloth and forms a pattern therein. These loops may afterwards
be cut, or they may be left uncut.

page_text: The threads of warp which are threaded through the unoperated healds (represented
at C) having been made "slack" by the partial rotation of the warp beam will be
drawn tight and clear of the "shed" by the weight of the rods bunder which they
pass, and when the figure requires it such threads of warp will be taken up by the pile
wire in the same manner as previously explained. Fig. 2 is perspective view of
the frame E shewing a single warp thread placed under each bar or rod b.
By the means above described, we are enabled to weave figures or patterns on pile
cloths with warp from off one beam, which cannot be done in the present arrangement,
as a considerable number of beams are required to form the pattern.
The warp may be of any required color and strength, and patterns may be made on
all kinds of fabrics where the pile is made from the warp such as-Seals, Curls,
Astracans, loops, plush, carpets, and rugs.
Instead of using rods or bars to weight the warp, a weight may be hung or
suspended from each thread of warp.
Our invention is equally applicable to either hand or power looms.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is:-
The use of rods or weighs or their equivalents for taking up the slack warp in
manner and for purposes substantially as set forth.
