REFERENCE CARDS OR COLOR GAUGES FOR TINTED THREADS OF TEXTILE FABRICS
Year: 1885

page_text: I, CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane in
the County of Middlesex, Consulting Engineer and Patent Agent do hereby declare
the nature of said invention for "REFERENCE CARDS OR COLOR GAUGES FOR
TINTED THREADS OF TEXTILE FABRICS" to be as follows:-
The reference cards now in use for indicating different shades of color in threads
or yarns for textile fabrics are formed of a strip of card on which are wound the
different shades of thread &c. According to the present invention such reference
cards or color gauges are prepared as follows: A woven fabric is prepared having a
double warp, of which the one warp, which may be of cotton, forms with the weft
the backing of the fabric while the other warp serves to produce the bands of
threads of varying shades. The bands of differently tinted or colored threads are
for this purpose arranged at certain distances apart on the warp beam and they
are interwoven at such intervals with the other part of the fabric as to leave
rows of loops thereof of any desired width unattached to the backing. The fabric
thus produced is then cut transversely into strips having each a row of loops of the
tinted threads and through these loops are now passed card strips having printed
thereon the numbers or other marks corresponding to the different shades of color,
such marks being made to appear in the spaces between the separate bands of
threads.
The woven strips may also be employed as color gauges without the insertion of
the cards. In this case there may be two or more loops of smaller width. on
each strip.
By the above described invention a saving of about one half the amount of
colored thread, as compared with the present reference cards having the threads
wound round them, is effected, and the manufacture of these reference cards is
effected much more rapidly and consequently more cheaply.

page_text: I, CHARLES DENTON ABEL of No 28 Southampton Buildings, Chancery Lane in
the County of Middlesex, Consulting Engineer and Patent Agent 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 :-
The reference cards now in use for indicating different shades of color in threads &
'or yarns for textile fabrics are formed of a strip of card on which are wound
threads of different colors or shades. According to the present invention reference
cards or color gauges are prepared as follows. A fabric is woven with two sets of
warps as shewn in elevation and section by Figs. 1 and 2 of the accompanying
drawings, the one set of warps, which may be of cotton, forming bands a, white or 1
colored and the other set, which are preferably of silk or wool forming alternate
bands b of the different colors or shades that have to be estimated. At intervals the
warps are crossed and held together by weft threads x. The fabric thus woven of
any desired length is cut into pieces, and, as shewn in elevation and section by
Figs. 3 and 4, a strip of card c is introduced between the alternate sets of warps a
and b so as to present the colored bands b on the front as in Fig. 3, and the other.
bands a at the back as shewn in Fig. 5. The spaces on the card between the
coloured bands 6 may be marked with numbers or other references.
As shewn in the elevation and section Figs. 6 and 7, the fabric may be woven
with a double warp, the one d white or of uniform colour forming the body of the
fabric, and the other in bands e woven in at intervals by wefts f these bands being
coloured.
The strip of card may be introduced under the loose coloured bands e, or the
piece of fabric may be used for reference without a card, in which case an
intermediate weft g may be used to keep the bands e in place.
By the above described invention, a saving is effected of about half the amount
of coloured thread, as compared with the present reference cards having the threads
wound round them, and reference cards of the kind described are manufactured
much more rapidly and consequently more cheaply.
:
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
The manufacture of reference cards or color gauges for tinted threads by weaving
a fabric with two sets of warps, one set of which presents at intervals bands of the
tinted threads, and cutting the fabric into suitable pieces each of which, with or
without a card strip introduced under the coloured bands, constitutes a reference
card or color gauge, substantially as herein described.
