The present inventionrelates to knitting ma
chines and to needles therefor.
In circular warp knitting machines, the needle
.is generally tipped or rocked on the knocking
over comb, in order, when moving up and down,
alternately to diverge from or move to one side
of the thread and then to catch the thread or a
thread lease or crossing. The tipping and mov
ing of the needle necessitates complicated needle
10 bars for its operation.
According to the invention, on the contrary,
the rocking out of the needle to catch the thread
is effected by a device which operates between
the needle and the needle-bed and presses out
For this purpose, a movable inter
mediate'piece is provided between the needle and
needle-bed, which rocks out the needle during
its descent in order to catch the thread or, a
.thread crossing or lease, while on the upward
15 the needle.

is inserted and secured by a screw 8, so'as to be
capable of being changed and adjusted, 9 de- 5
notes threads or thread crossings, which are
caught by the hooked end of the needle to form
the knitted fabric ll.

.
In Figure l the needle is shownin its highest
position. At the beginning 01' the descent. a stop 10
. comes into operation between the point of the
lever 5 and the teeth 6, so that the needle on its
further descent is rocked out by the action of
the lever, catches the thread 9 (Figure-2) and
15
descends with the thread (Figure 3).
Towards the end of they descent the lever 5
comes out of engagement with its counter-stop ‘I
and passes into a su?lciently large recess I! in
the needle-bed or the stop ‘I, so that the‘ expand
ing action ceases and the needle returns to its 20

counter-stop, formed for instance by a toothed
rock, and the movable intermediate piece again
resumes such a position that the needle in its
upward movement in the non-expanded or

‘thread crossing.
The accompanying drawing illustrates one ex
ample of construction of the invention, and show
various positions of the needle in the needle-bed.
Figures 1 to 5’ are sections through a needle

bed, in the grooves of which the needles are
moved up and down in known manner.

Figure 6 is a plan view of a portion of the
needle-bed, with the needles in the highest posi
45 tion shortly before the needles again descend and
catch the thread leases or crossings.

Figure 7 shows a single needle having‘ a piv

a recess III on each needle, while on the opposing
part of the needle-bed a toothed rack-bar ‘I hav
otally arrahged lever in the expanding position.
Figure 8 shows a single abutment in the form
of a toothed rack-bar for the said lever.
The needle-bed I has grooves 2, in which the
needles 3 are moved up and down. The needles
are held and pressed on_ the needle-bed in known
manner by a helical spring I. [A lever I for
55 pressing out the needle is plvotally mounted in
'
except for a projecting small point, so that the 25
needle on its upward movement can move to one
side of the thread 9, as Figures 6 and 1 show. ,
- The lever or other movable stop acting on the
needle as an expanding or rocking out member,
may also, conversely, be arranged on the needle- 30
bed i, in which case the counter-stop,’ e. g., the
toothed rack ‘I will be arranged on the needle
itself. The lever may also be replaced by a cam
or the like.
I claim:--
