PROVISIONAL SPECIFICATION.
Improvements in Knitted Fabrics.
We, JOHN WATERFIELD, of 32, Longmont Street, Providence, Rhode Island,
United States of America, Machinist, WILLIAM BADCOCK, of 158, Amherst Road,
Hackney, Merchant, and HENRY BALDWIN EDWARDS, of 3D, Clarence Mansions,
Marylebone, Gentleman, both in the County of London, do hereby declare the
nature of this invention to be as follows:-
--
This invention relates to knitted fabrics intended to resemble ordinary diagonal
woven cloths.
The class of knitted fabrics to which the invention more particularly has
reference is that having longitudinal or warp threads and transverse or weft
threads, the latter being divided into two sets termed respectively plain weft
or filling threads and knitted or looped weft threads.
According to the said invention the loops of the knitted weft thread instead
of being arranged as heretofore so that they alternate regularly with the warp
threads, are disposed so that they miss or skip some of these threads.
Thus, in a fabric intended to resemble an ordinary diagonal, the loops in one
row might be arranged to lie between alternate pairs of warp threads, while
those of the next row would lie between the intervening pairs. Thus the loops
of one row would break joint as it were with those of the adjacent rows, and the
desired diagonal pattern would consequently be obtained.
By varying the arrangement and operation of the needles in the knitting
machine, diagonals may be made having the loops arranged in this way, in which
the pattern runs either to the right or to the left. Moreover, the fabric may be
made up of left handed work alternating with right handed work as in some
ordinary woven fabrics.
In some cases in order to obtain a greater variety in the work produced, the
knitted weft threads may be arranged between every third pair of warp threads.
or otherwise, instead of between alternate pairs of warp threads as in the example
given above.

We, JOHN WATERFIELD, of 32, Longmont Street, Providence, Rhode Island,
United States of America, Machinist, WILLIAM BADCOCK, of 158, Amherst Road,
Hackney, Merchant, and HENRY BALDWIN EDWARDS, of 3D, Clarence Mansions,
Marylebone, Gentleman, both in the County of London, 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, reference
being had to the accompanying drawings and to the letters and figures marked
thereon, that is to say:-
This invention relates to knitted fabrics intended to resemble ordinary woven
cloths,
The class of fabric to which the invention more particularly has reference, is
that having longitudinal or warp threads and transverse or weft threads, the
latter being divided into two sets termed respectively plain weft or filling threads,
and knitted or looped weft threads.
According to the said invention, the loops of the knitted weft thread, instead
of being arranged as heretofore, so that they alternate regularly with the warp
threads, are disposed so that they miss or skip some of these threads.
Thus, in a fabric intended to resemble an ordinary diagonal, the loops in one
row might be arranged to lie between alternate pairs of warp threads, while
those of the next row would lie between the intervening pairs. Consequently,
the loops of one row would break joint as it were with those of the adjacent rows,
and the desired diagonal pattern would be obtained.
An example of a fabric, such as referred to in the preceding paragraph, is
shewn in the annexed drawings, in which:
Figure 1 illustrates diagrammatically and considerably enlarged, the front,
and Figure 2 the back of the improved textile fabric; Figure being a longi-
tudinal section and Figure 4 a transverse section.
a are the warp threads, that is to say the threads which run longitudinally
of the fabric, and b are the plain weft or filling threads. These latter extend
transversely across the fabric and are quite straight, that is to say; they are not
bent in and out between the warp threads, but lie straight across them on one
side thereof only. In this way, these threads serve to prevent the fabric stretch-
ing in a transverse direction, just as the warp threads prevent longitudinal
stretching.
e are the knitted or looped weft threads which are laid on the opposite side
of the warp threads to that on which the filling threads lie. They alternate with
the filling threads, and pass through the fabric from one face to the other, thus
serving to tie or knit the other threads together. On the face or front of the
fabric, (Figure 1) the said threads form loops e¹ between alternate pairs of the
warp threads, the legs of the loops lying parallel, or approximately so, with the
warp threads but on the outer side of the filling threads, which latter are thus
firmly held between the warp threads and the said legs of the loops. In the
fabric shewn in the drawings, each loop is of such a length that its legs extend
over two filling threads, and engage the corresponding loop in the next knitting
thread but one. It will be seen that the loops in one row break joint with those
in the next row and thus give the diagonal appearance to the fabric. In other
words, the loops c¹ of the threads c follow each other across the fabric in diagonal
lines and thus give a pattern similar to that of an ordinary woven diagonal.
Knitted diagonals of this kind may have the loops arranged to run either to

page_text: the right or to the left, or may be made up of left handed work and right
handed work alternating with each other, or checkerwise, as in some woven
fabrics. To this end, the loops of the knitted weft threads may be arranged
between every third pair of warp threads, or otherwise, instead of between alter-
nate pairs of warp threads, as in the example given above.
Fabrics made as above can advantageously be produced on the circular knitting
loom described in our Specification No. 11881 of 1898.
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:-
1. A knitted diagonal fabric resembling a woven cloth and having its threads
and loops arranged substantially as described.
2. A knitted fabric comprising, in combination, longitudinal or warp threads,
filling threads extending straight across said warp threads on one side of them
only, and kuitted threads passing through the fabric from one face to the other
and having their loops arranged so that those in one row lie between different
pairs of the warp threads from those in the next row, substantially as described.
