Improvements in the Manufacture of Scotch or Ingrain Carpets and
in the Process Adopted therefor.
We JAMES SAMUEL COOKE, Carpet Manufacturer, and JOHN WILLIAM BROOK,
Designer, both of Spen Valley Carpet Works, Liversedge, in the County of York, do
hereby declare the nature of our said invention to be as follows:-
By this improvement we can bring up distinct solid colours of weft with the usual
two ply warp and so interweave it as to obtain one solid fabric of carpet in the place
of a carpet having separate and distinct plies or fabrics tied together at intervals of
the pattern.
According to my invention when the design of the carpet has been completed in
say four colours, as for example, crimson olive, black and blue, there will be required
four stamped cards for each cord or line in the design, which cards must not be
stamped in the ordinary manner but as follows namely:-
1st card stamp blue, to produce blue.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Scotch or Ingrain Carpets and
in the Process Adopted therefor.
We, JAMES SAMUEL COOKE, of Spen Valley Works, Liversedge, in the County of
York, Carpet Manufacturer, and JOHN WILLIAM BROOK of Liversedge, aforesaid
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 relates to improvements in the fabric of Scotch, or ingrain carpets
and consists in bringing up distinct and solid colours of weft with the usual two ply
warp, and so interweaving same as to obtain one solid fabric of carpet in the place of
a carpet having separate and distinct plies or fabrics tied together only at intervals of
the pattern.
To clearly explain the nature of our invention reference is made to the accompanying
drawings in which:
Fig. 1. 2. 3 and 4 are diagrams of different fabrics in accordance with our
invention.
Fig. 5 is a diagram showing the present method of forming the fabric of these
carpets.
Fig. 6 is a sketch plan view shewing the design of a carpet for the purpose of
illustration.
Referring first to Fig. 1 the wefts threads are supposed to be white, olive, black and
red, as indicated by the letters. W. O. B. R, and the warp threads olive and red as
indicated by the letters, o. r. This figure shows the manner in which the warp and
weft are interlocked so as to forin one solid fabric which in this case will be all white
on the surface as shown. Fig. 2 shows the fabric when the olive weft threads have
been brought up so as to show an all olive surface. Fig. 3 shows all black, and Fig. 4
all red.

page_text: If the same colours were employed in the ordinary 2 ply weave, it would be by
means of shot and shot thereby losing half the effect of each colour and making two
distinct cloths bound only at intervals of the pattern as shown in Fig. 5 which has the
same coloured warp and weft threads and which shows the two distinct fabrics or sets
of pockets which a carpet as at present formed consists of.
According to our invention where the design of this carpet has been completed,
say, in four colours. such as the white, olive, black, and red, before referred to and
indicated by the letters W. O. B. R, in the design or pattern of a carpet shewn in
Fig. 6, there will be required four stamped cards for each cord or line in the design,
which cards must not ie stamped in the ordinary manner but as follows:-
1st card, stamp red to produce red.
2nd card, stamp olive, black and red to produce white.
3rd card, stamp white, black and red to produce olive.
4th card, stamp black to produce black.
The above cards are stamped to work with planes or journals and a double lift
jacquard, and in doing so the same planes and board are made to lift twice together,
as shown in the table below, instead of each plane and board lifting alternately as in
the ordinary warp.
Similar results may be got by picking one ground and then one figure alternately if
the cards are placed accordingly.
Having now particularly described and ascertained the nature and object of our
said invention and in what manner the same is to be performed, we declare that
what we claim is :-
A carpet fabric wherein the four colours of its weft are each brought up to the
surface and each form a solid colour of weft, the warp threads being so interwoven
with the weft that the whole forms a solid fabric of carpet substantially as described.
Dated the 30th day of June 1890.
