IMPROVED MEANS OR METHOD OF PRODUCING OR FORMING DESIGNS OR FIGURES UPON WOVEN FABRICS DURING THE OPERATION OF WEAVING
Year: 1886

page_text: We, JOHN WALKER and ALBERT EDWARD WALKER of Claremount, Halifax,
Yorkshire, Manufacturers do hereby declare the nature of our invention for
IMPROVED MEANS OR METHOD OF PRODUCING OR FORMING DESIGNS OR FIGURES
UPON WOVEN FABRICS DURING THE OPERATION OF WEAVING," to be as follows:-
66
The object of our invention is to produce designs or figures upon woven fabrics
during the operation of weaving, and this we accomplish somewhat in the following
manner.
To commence with we employ warp threads twisted in opposite directions-that
is to say one warp is twisted right handed and the other warp twisted left handed,
and these two warp threads are arranged when weaving side by side, and are
alternately right hand and left hand twisted warp threads up to the end of each
series.
An ordinary "dobby" is employed in connection with the loom, and it is arranged
to lift a series, or a number of series of threads (the number varying according to
pattern) which are alternately right and left hand twisted threads, the first of one
series commencing-say with a right hand twist and terminating with a left hand
twisted thread, whilst the adjoining series of threads would be visa-versa-that is
to say the series would commence with a left hand twisted. thread and terminate
with a right hand twisted thread and the next adjoining series would be like the
first illustration and so on, one after another the change of twisted thread in each
series shewing a line of demarkation, and in all and every series of threads, the
first and last thread are opposite twisted warp.
Goods composed of the peculiar warp herein referred to and manufactured in
the manner set forth whilst in the grey state will when dyed; shew the pattern
intended to be produced.
The above method of selecting the warp threads would only produce checks,
plaids, diamonds, diagonals, and other geometrical figures, but to produce flowers,

required instead of an ordinary "dobby."
In the above method of weaving the warp is thrown on the face of the cloth,
and the weft at the back thereof, or in some cases part of the weft is thrown on
the face of the cloth to vary the pattern.
