Improvements in Weaving Check or Coloured Crossover Goods.
1, FRANK HEATHER, of 3 Newmarket Lane, Manchester, Merchant, 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 improvements relate to the weaving of checks or coloured cross overs in
woven goods, and have for object the weaving of the same with one shuttle or
weft thread only, and also to render possible gradations of shade in the weft forming
such crossover stripes.
As is well known, when it is desired to weave goods having stripes across the
piece of weft of various colours the present practice is to employ looms fitted with
drop-boxes or revolving or other multiple shuttle boxes, actuated by suitable
mechanisms for alternately bringing into operation first one shuttle and then
another, thus producing crossover stripes in the weaving of checks and the like,
which are clearly defined, there being a complete transition in all cases from one
shuttle thread to another. By my improvements, checks or other crossover stripes
may be woven with two or more colours, which may either be clearly defined in
their changes, or allowed to gradually blend or change from one colour to another,
as may be desired.
To effect this and to accomplish my improvements, I employ the ordinary or
other one shuttle loom, the weft for weaving therein being all on one cop or pirn,
and of a continuous thread throughout its length.
The different coloured crossover stripes I obtain by dyeing the weft yarn, either
in the hank or otherwise, by means of what is known as the tie and dye or analogous
method, in lengths sufficient to weave crossover stripes of such breadth as is
determined by the pattern desired.
The colours can, by this means, be cut off sharply and thus produce well defined
checks or crossover stripes or they may be permitted to tone or shade away from
one to another, producing a more hazy effect in the weft, and thus enable the
weaving of checks and crossover stripes to be accomplished by means of one shuttle
thread only.
I am aware that tie and dye production of colours in weft yarn has been
employed for producing yarns having short lengths of varying colours therein, for
the weaving of mixtures or irregular combinations of coloured goods; but these
are entirely different from this my present invention, which is intended to produce,
with one shuttle only, entire crossover stripes of varying colours, for the manufacture
of checks and the like.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The weaving of checks or crossover stripes by means of one shuttle only,
the weft in which has been dyed in the requisite colours of sufficient length in each
colour, for the purpose and in manner substantially as herein described.
2. Woven goods having checks or crossover stripes therein of different colour to
the ground, all of which have been produced by means of a single thread of weft
or shuttle, for the purpose and in manner substantially as hercin described.
