10 Claims. . (CI. 66-90)
The present invention relates to ?at rib knit
ting machines and more particularly refers to
?at rib knitting machines provided with a'
jacquard controlled patterning device for the
5 manufacture of ribbed-fabrics showing wrap pat
terns, tuck-patterns and tuck-patterns on a
double sided fabric respectively and wrap-tuck
patterns.
'_
Hitherto ribbed-fabrics provided with wrap pat
10' terns, tuck-patterns and tuck-patterns on a
double sided fabric respectively and wrap-tuck
patterns have been produced by reciprocating in
one level the roller over which the jacquard cards
are led. The jacquard cards were provided with
two or more rows of perforations depending upon
the kind of pattern to be produced. By shifting
the jacquard roller in the direction towards the
frame needles, the wrap ‘guides’ are operated,
whereas by shifting the jacquard roller in the
20 opposite direction, slides are operated which in
turn,‘ by means of a, lever system, actuate the
press instruments.
-
With these known constructions, the row of
perforations acting upon the wrap guides must be
95 arranged in another jacquard card than the row
of perforations serving to influence the press in
struments. As the jacquard roller is reciprocated
without being turned, the press instruments must
be actuated by the jacquard card arranged upon
30 the side of the jacquard roller opposite to that
upon which the jacquard card acting upon the
row of perforations only.
-
For the purpose of producing wrap patterns
and for the purpose of making tuck-patterns or 5
tuck-patterns on a double sided fabric respece
tively, the jacquard card is moved in one position
only in the direction towards the wrap guides,
for instance for the manufacture of wrap pat
terns in the lower position and for producing 10
tuck-patterns or tuck-patterns on a double sided
fabric respectively inv the upper position.
In producing wrap-tuck patterns, the jacquard
card provided with two or more rows of perfora
tions arranged in one leaf one beneath the other 15
is, by means of the jacquard roller, shifted in two '
levels in the directiontowards the wrap guides
and the press instruments and in a direction at a
right angle thereto.
As the press instruments and the wrap guides 20
are in?uenced by moving the jacquard roller in
the same direction, the substantial advantage is
obtained, that the transmission members re-‘
quired with the known constructions for displac
ing the press instruments are super?uous. The 25
press instruments are, like the wrap guides, di
rectly controlled by the jacquard card. Accord
ing to the level into which the jacquard roller
has been adjusted, the rows of perforations of one
and the same jacquard card act upon the wrap 30
guides or the press instruments.
‘
If wrapping over one needle is e?fected by a
wrap guides is arranged.
Besides a great wear of the cards, this arrange
ment has, in carrying out certain patternings,
35 the disadvantage, that the designing of such pat
terns is extremely di?icult and in most cases sub
ject to faults. A very great practice is required to
correctly provide the individualperforations in
the two jacquard cards, as the same cards also
40 have separated perforations used for a further
row of patterns.
of patterns. This card may be provided with a.
plurality of rows of perforations or with a single
‘
group of wrap guides and if, therefore, the locally
equally journalled wrap guides and press instru'—
ments are to be in?uenced, the two rows of per- 35
forations arranged one above the other in the
same card may also be combined to a single row.
In the accompanying drawings two construe:
tions according to the invention are shown by way
of example.

In these ‘drawings:
_
Figs. 1-3 show the parts of a ?at rib knitting
machine which according to the invention come
into consideration in the position of rest, in the
position for actuating the wrap guides and in the 45
' or lever system and, therefore, is complicated I position for actuating the press instruments re
spectively,
and extremely delicate.
‘Another draw-back of the known device con
sists in the transmission of the movement of the
slides upon the press instruments. This trans
45 mission can only be effected by way of a_ link
‘The device, forming the subject matter of the
present invention, avoids all these draw-backs
50 by the fact, that for the purpose of selecting the
operation of the wrap guides and the press in
struments the roller guiding the jacquard card
is displaceable in several planes in such a man
ner, that for producing the various kinds of pat
55 terns a single jacquard card is used for each row

The frame needles I, the rib needles ,2, the jack 55

sinkers 3 and the general presser 4 are arranged
in the usual manner. The wrap guides 5 are
mounted in a frame 6 and in the position of rest
their heads lie beneath the frame needles. A dis
placeable rod 1 acts upon the- wrap guides 5.
The press instruments 9 are displaceably ar
ranged in guides 8 of the frame 6 in front of the
frame needles I. A_ displaceable rod l0 acts upon
the press instruments.
Pivotally mounted upon a shaft H is a jacquard
roller l2 which carries a jacquard card i3. The
shaft H is journalled in arms not shown in the
drawings which may be oscillated to allow shift-.
ing of the shaft II in a lower horizontal plane, a
15 vertical plane and an upper horizontal plane.
According to the pattern to be produced each leaf
of the jacquard card I3 is provided with perfora
tions, for instance, as shown in Fig. 4 with two
rows of perforations I4 and l5. ‘
In Fig. 1 the individual parts of the device are
shown in the position of rest. If now the wrap
direction of the arrow .1: in Figs. 1 and 2 and the
lower row H of perforations in the jacquard card
I3 is rendered operative. As in the manufac
ture of wrap patterns, the advanced wrap guides
place their threads around the oppositely ar
ranged frame needles I by lifting and lateral
displacement of the frame 6. Thereupon the
jacquard roller [2 is returned again into the posi
tion of rest in the direction opposite to that of
the arrow :1:, i. e. in the direction‘ of the arrow z
in Fig. 3. The wrap guides 5 are returned into
their position of rest again by the rod 1. There
upon the jacquard roller i2 is lifted in the ver
tical plane in the direction of the arrow z’ and
?nally shifted in the upper horizontal plane in 15_
the direction of the arrow 2" towards the press
instruments 9, so that now the upper row l5 of
perforations in the card l3 may act upon the press
instruments 9 (Fig. 3). Of course, the rows l4
and I5 must for this purpose be provided with the‘ 20
required perforations corresponding to the pat
guides 5 are to be operated to produce wrap pat
terning. By means of the rod III, the press in

If the press instruments are to be operated for

Jacquard roller 12 is lifted in a vertical plane
in the direction of the arrow 1/ from its position
of rest shown in dotted lines 'in Fig. 2. Then
50 the jacquard roller I2 is shifted in the direction
of the arrow 1/’ towards the press instruments 9,
that is to say, the roller I2 is shifted in the up
per horizontal plane. Thereby, for instance, the
upper row l5 of perforations in the jacquard card
55 l3 acts upon the press instruments 9. If per
forations are present, the jacquard roller 12 is
shifted over the rear ends of the press instru
ments, whereas’ the other press instruments.
are moved by the jacquard card I 3, so that the
60 front end of these instruments is brought into
a position above the frame needles I. By means
of the general presser 4 the beards of the corre
sponding frame needles are pressed in a well
known manner. The advanced press instru
ments are returned again into the position of rest
by the rod l0 as soon as the pattern row is
?nished. ‘For the manufacture of tuck-patterns,
the wrap guides correspond to the perforations
required for the press instruments. In this case
it is also possible to combine the two rows of per
forations of the locally equally arranged guides 45
and press instruments. The wrap guides or the
press instruments may in such a case also selec
tively be in?uenced by shifting the jacquard card
in different planes.
