Improvements in Knitting Frames.
We, BRUNO SALZER and GUSTAV WALTHER of Chemnitz in the Kingdom
of Saxony, Engineers, 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 :-
This invention relates to the provision in knitting frames or machines of means
for quickly changing from the ordinary close stitch or mesh to an open or wide
stitch or vice versa.
Referring to the accompanying drawing, by open stitching (Laufmaschen) is
meant the formation of very wide meshes (Fig. 1) one above another between two
ordinary close stitches (Glatten Maschen) n the wide stitching being frequently
employed for the purpose of ornamentation and hitherto has usually been produced
by removing one of the needles from the frame at a particular place, say n¹ or by
permanently doubling up the hook of such needle so that meshes cannot be formed
by it but should it be desired to follow a piece of open stitch with close stitch as
shewn in Fig. 2, it is then necessary to place needles at all the respective places n'
(Fig. 1) along the width of the knitting frame or again open out their hooks or
place the work on another frame furnished with needles for close stitching and
work from p (Fig. 2). In this way of working there is however a great loss of time
to prevent which is the object of this invention. By its means the ordinary close
stitch may in the same machine be quickly changed to open stitch.
The invention consists in the application of a particular knitting rake b
(Figs. 3, 8) in the form of a rail with several knitting teeth a which when open
stitch is to be done are so placed in the machine that they come between the frame
needles n² and as shewn in Fig. 8, also slightly between the falling bars t. If, now
knitting is done by the falling barst pressing the thread m (Fig. 3) in between
needles n with the object of forming loops, this thread will then lie over each
knitting tooth a and consequently at these places a longer loop is formed than is
the case on the other needles. When all the loops have been formed the rail b
with teeth a descends and the loop (or loops) carried by a falls on the contiguous
needle and as indicated by (Fig. 4) hangs down. Needles n' also seize the loops
when does not descend with a but this must take place during the turning of the
loops because rail must shunt the turning mechanism. The long loop 1 (Fig. 4)
then forms in the goods, notably when these are equably stretched out the open or
wide stitch of Fig. 1.

The rail is provided with knitting teeth a at all the places in the width of the
goods where open stitch is to be done. In order render certain the pressing down
of the work at the open stitch places the striking teeth s (Fig. 5) are at these
places given a greater width ', and Figs. 5 and 6 shew that then the narrow
striking teeth s will press down the ordinary close stitch meshes n and the wider
teeth s the open stitch meshes in a proper manner. When ordinary close stitch
goods are to be made the rake b is removed and the whole of the pressing comb g
with teeth s,, (Figs. 8, 9) placed so high that the wide teeth si (Fig. 7) strike
with their narrow parts u in quite the same way as the narrow teeth s.
knitting rake may have teeth of different heights and the pressing comb g
The
striking teeth of different widths as shewn at a, a, and s, s', s' in Fig. 11 for the
purpose of producing different widths of open stitch.
The knitting rake & may be set in its place and removed therefrom without loss
of time. It may, for example, as shewn in Fig. 8, be mounted in lateral guide
grooves d and by pivot brest on arms e of needle bar f so that upon this latter
going back, that is after knitting, it will of itself fall down underneath the row of

page_text: needles n². The raising and lowering of the pressing comb g may also be quickly
effected, for example by means of excentric hon lever h¹ (Figs. 8, 9). By this
means the connection of ordinary close stitch work from p (Fig. 2) upwards with
open stitch work and vice versa may be immediately effected.
The mechanism of the invention is suitable both for frames with horizontal and
those with vertical needles. For the latter case it is shewn in Fig. 10. The
knitting rake turns on so that it may be laid in the line of the needles or
removed therefrom, or lie at rest as in frames of this kind the row of needles after
knitting are moved to the press v.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A kuitting frame which, for the purpose of quickly changing from close to open
stitch and vice versa, is provided with a removable knitting rake having knitting
teeth a and with a pressing comb 9 having teeth of different widths 5, s', s², the
whole arranged in such a way that in working open stitch the thread passes over
teeth a projecting from the plane of the needles, the work at these places being
pressed by the wider upper part s' of teeth of comb g, whilst for the production of
close stitch the knitting rake is removed and the pressing comb raised so that all
the striking teeth have the same width s. u, for operating on the work, substantially
as described and shewn.
