This invention relates to Jacquard devices for
fiat knitting machines, pearl knitting machines or
the like for producing a great number of pattern
effects, and most particularly to machines having
5 a plurality of needle lock slides cooperating with
each other in collateral positions (double or triple
cam slide machines or the like).
With known machines of this kind, the aux
iliary needles selected by the Jacquard device
10 are pushed Within the range of operation of aux
iliary lock slides and raised by the latter to such
an extent that auxiliary heels on the corre
sponding needles project above the needle bed,
so as to provide for the main needle lock slides
15 to advance the needles. All of the needles se
lected for cooperation with a certain needle lock
slide by the Jacquard device perform the same
knitting movements, that is, equal advance and
retracting movements through the needle guide
20 ways.
'
Those known machines in which the pushers
selected by the Jacquard device raise the main
and auxiliary needle jacks directly, for the pur
pose of moving the heels thereof within the range
25 of operation of the needle lock slides, operate in
like manner.
-
Other known machines are provided with‘Jac
quard sinkers that can be adjusted according to
a pattern for directly moving during their ad
30 Vance movement the needle jacks or other knit
ting members into movement change-over posi
tion for being influenced by corresponding cam
portions of the needle'lock slide, in order to- pro
vide for retracting the needles in accordance with`
35` the pattern in this manner. All of the needles
selected for cooperating with a certain needle lock
slide for being retracted in the same sense are,
also in this arrangement, compelled to perform
equal knitting movements.
40
There are further Jacquard arrangements
known, particularly for combination with double
cam slide machines, in which two relatively in
dependent pushers are so distributed by the Jac
quard device that any desired group of needles
45` can be selected for cooperation with both lock
cam systems, each selected group of needles be
ing, however, compelled to perform the same knit
ting movements as determined by the corre
spondingly adjusted needle lock slide.
Apart
50> from the drawback inherent to all the known
‘ arrangements mentioned above that the needles
selected for cooperation with any one` of the nee
dle lock slides perform the same knitting move
ments, and can thus all be selected but once,
.in 5` this arrangement has the further drawback that
all theneedles, needle jacks and the like that
remained in inoperative position must be read
justed by the‘needle retracting cams anew in
which way the risk of mesh breakage is involved.
According to" the present invention, all the 5
aforesaid drawbacks are eliminated by the knit
ting‘members‘viz., needles, needle jacks or the
like occupying positions within the range of op
eration> of a slide lock being so controlled, for
the 'purpose of selectively varying the lengths of 10>
the needle movements, with the aid of auxiliary
push means, which are selected for cooperation
with an auxiliary slide lock and at least two of
which are associated with an individual knitting
member, through the medium of an intermediary 15
member, that projections or heels of said knitting
members are caused‘to cooperate with correlated
slide `lock cam portions.
‘
‘
‘
In this manner is accomplished that the needles
which are `correlated to one and the same lock ‘2d
slide are adapted to knit conjointly either cardi
gan‘ stitches,`long stitches, short stitches etc., as
selected according toa pattern, without requiring
depressible or stepped off cam portions to be pro
vided in the lock slide.
`
25
Also, when applied to pearl knitting machines,
the invention permits to control in accordance
with a pattern the needle jacks or needles, as the
case may be, which are correlated to an individual
lock slide, so as to shift partly in any direction, 30»
that is,` to the r'ear or front needle bed, partly to
assume` cardigan stitch forming positions, and
partly to shift for forming long or short stitches.
„In this way the greatest amount of dilferent
patterning possibilities isprovided for.

means of projections or snugs 3'. II indicates
intermediary members for controlling the needle
jacks 3 to assume their raised positions, said
members being guided by an auxiliary bed I2,
rigid with the main needle bed* I, and the numer
als I3, I4, I5 and I6 indicate auxiliary push means
or pushers which are guided by the intermediary
members I I, and locked thereto in their operative
30 and inoperative positions. By I'I that Jacquard
pattern card is denoted, which cooperates _at the
time being with the pushers, and by I6 the aux
iliary lock face plate provided with the stationary
25
cam portions I9, 23, 2|, 22 and 23 as well aS. With
35 cam portions 24, 25, 26 and 2‘I that are depress
ibly arranged for alternate control at either end
of the machine, in a known manner, and with
triangular knock over cams 28, 29, 3|) and 3|
that _are also adapted to be moved into or out
of operative position by alternate control at ei
ther machine end. By 32 locking members on
45
the needle bed I are referred to which by engage
ment With rests 33, such as kerfs, stops or the
like on -needle push members, as the jacks 3,
secure the latter in their inoperative positions,
as well as in their operative positions.
The auxiliary bed I2 is provided in the bed
as Well as in the yoke portion with a plurality
of parallel slots extending in the vertical direc
tion as regards Figs. 1 and 2. The intermedi
ary members II and II’ are guided bythe slots
i'n the bed portion by means of pin and slot
connections 43 (Fig. 5). The auxiliary pushers
I3 to I6 and 34 to 39 are guided, with their front
55 portions, by the intermediary members II and
I I’ respectively between two opposite projections
40. On the other hand, the auxiliary pushers
are guided with their rear portions in the slots
60 of the yoke portion of the bed I2 between pins
42, which pass through the webs left between
the slots in the bed portion of the auxiliary bed
I2 throughout the width of the latter the same
as the pins 43 in the bed portion, In this way
65 passages providing cross bores are formed in the
bed and yoke portions in which the auxiliary
pushers are positively guided longitudinally and
transversely. The projections or noses 40 may
at the same time serve as locking members for
7.0 securing the pushers in their operative> and inop
erative positions by engagement', for example,
with notches 4I, as shown.
The various possibilities of selecting and mov
ing active parts as intended according to the
7.6.» invention are the following.
During the traverse of the needle lock slide in
the direction of the arrow in Fig. 4:
The knock over triangular cams 28 and 23 are
rendered inactive by the change-over mechanism,
so that the auxiliary pushers I3 or I4 respectively
that are advanced at a time by a Jacquard card,
in a known manner, can enter the cam slot of
the auxiliary slide lock unhindered (position as
indicated by line I-I in Figs. 3 and 4).
1st patterning possibility-«All the auxiliary 10
pushers assume their inoperative positions by
which is meant that they are not advanced (for
example pusher I4 in Fig. 1). During the slide
passing by the auxiliary pushers the tips thereof
(e. g. I4’) are not gripped by the auxiliary lock
cam portions 22, 23 and are thus not raised.
Consequently the corresponding intermediary
members II together with the needle jacks 3
held thereby retain their low positions shown in
Fig. 1 (inoperative position), and are secured 20
therein b-y the locking members 32 interengaging
with the kerfs 33. The heels 2’ of the needles 2
enter the slots between the main lock cam por
tions 5, 6 and 5, ‘l’ respectively thereby to be
guided rectilinearly during the whole traverse of 2.5.
the slide. Therefore, the needles 2 are not moved
and remain in their positions of alignment.
`2114i patterning possibility.--'I‘l1e upper auxil
iary pushers I3 are in action, i. e. advanced by
the Jacquard patterning card I'I, whereas the 30.
lower auxiliary pushers I4 are inactive. 'I‘he aux
iliary lock cam portions I9 and 22 grip the tips
I3’ and heels I3" of the pushersy I3 thereby to
align the heels (line I-L Figs. 3 and 4). The
auxiliary lock cam portion 24 which is moved
into operative position by the change-over mech
anism raises the auxiliary pusher I3 and thereby
the intermediary member I I as well as the needle
jacks 3, so that the heels 3’ of the latter project
_out of the needle bed I (line II-II in Figs. 3
and 4, and Fig. 2). During this raising move 4.9
ment of the needle jacks 3 the needles 2 are
maintained in aligned positions by the needle
lock cam portions 5, 6 with the aid of their heels
2’. The tips I3’ of the auxiliary pushers I3 con 45
tinue to slide rectilinearly along on the auxiliary
lock cam portions 24 and 22 up to a position as
indicated by line X--X in Fig. 3 during which
movement the heels I3” pass freely through the
slot formed by the U-shaped lock cam portion 50
20 (lines VII-_VII and VIII-VIII in Fig. 3).
During this movement the heels 3’ of the needle
jacks 3 follow the contours of the needle lock
cam portion 8 up to its apex (line VIII-VIII in
Figs. 3 and 4) in which way the needles 2 are 55
advanced completely thereby to produce stitches,
While the heels 2’ of the needles 2 follow the
contours of the needle lock cam portion 6 (from
line VIII-_VIII to line XI-XI in Figs. 3 and 4)
in which way the needles 2 are retracted. During 60
this complexity of movements (from line III-III
to line XI-XI in Figs. 3 and 4) each group of
needles and needle jacks coupled together by
means of the heels 2’ and 3’ remains at all times
safely guided on both sides between the needle 65
lock cam portions 6, 8, so that jumping is avoided.
In the position as indicated by line X--X in Fig.
3, the heels I4” of the auxiliary pushers I4 not
having been moved into operative position enter
into engagement with the inclined plane of the 70
needle lock cam portion 21 having been moved
into operative position by the change-over mech
anism and are thus shifted downwardly. In this
way the needle jacks 3 are 'again depressed in
the needle bed I, into their inoperative posi
75
3
2,116,761
tions in which they are secured by the locking
members 32, through the interventionof the in
termediary members I I, the heels 3’ of the needle
plained, viz., complete advancement of the nee
dles (up to line VIII-_VIII in Figs. 3 and 4)` for
forming loops; complete retraction (up to line
jacks thus disengaging from the corresponding
XIII-XIII in Figs..3 and 4) , therefore long loops
needle lock cam portions.` Theneedle heels 2’
then continue to slide rectilinearly on needle lock
cam portion 6, whereas the needles 2 remain in
positions of alignment and have thus formed
short stitches. On passing out of the auxiliary
10 lock cam slot the operative auxiliary pushers i3
are moved back into their initial positions again
by means of the triangular knock over cams 30.
3rd patterningI possibility-Lower auxiliary
pushers I4 are operative, that is, are advanced by
15 the Jacquard pattern card I‘I, whereas upper aux
iliary pushers I3 remain inactive and the tips I4’
are gripped by auxiliary lock cam portion l23,
thereby being raised. The heels 3’ of the needle
jacks 3 thus emerge from the needle bed I. The
20 tips I4' then keep on sliding rectilinearly on aux
iliary lock cam portion 23 and the heels 3' follow
the contours of the needle `lock cam portion 8 up
to the position as indicated by line V-V in the
Figs. 3 and 4. The needles 2 `are advanced half
25 way, thereby forming cardigan loops. The heels
I3” of the inoperative auxiliary pushers I3 enter
into engagement with the inclined plane of the
auxiliary lock cam portion 20 and are thus shift
ed downwardly. Consequently the heels 3’ of the
30 needle jacks are depressed again in the needle bed
I and are therefore disengaged from‘the needle
lock cam portion 8 beyond line V-V (Figs. 3
and 4). During this working incidence the needle
heels 2’ remain guided in the cam slot between
35 needle lock cam portions 6 and ‘l at both of their
opposite guide edges. The tips I4’ oi“ `the opera
tive pushers I4 are then raised again by auxiliary
lock cam portion 23 and the heels 3’ of the needle
jacks 3 project out of the needle bed I again, the
40 needle 2 being retained anew in the cam slot be
tween cam portions 6 and ‘I (line X--X Figs. 3
and 4). 'I‘he tips I4’ of the auxiliary pushers I4
now keep on sliding rectilinearly on the auxiliary
lock cam portion ‘23 during‘which movement the
45 heels I4" pass freely through the passage formed
are formed.

,
Duefto the construction of the locks being sym
metrical all movements‘described above are car
ried out during the opposite traverse ofthe slide
in exactly the same manner.
`
i
.
In double cam slide machines having‘two col l0
lateral main needle locks (Fig.` 4), an auxiliary
lock exactly like that described above with refer
ence to the lower part of Fig. 3 is arranged in
the transverse middle axis of the` upper main nee
dle lock shown in the upper part of Fig. 4;
.
.
I3 and I4 (Figs. 1 and 2) and are selected by one
.and the same Jacquard patterning card` I'I which 25
to this end is provided with four rows of punch
ings.
,
For triple cam slide machines accordingly a
third auxiliary _lock and two further auxiliary
pushers are provided. Referring to Fig. 3, this 30
third auxiliary lock of a similar construction as
previously described would join with the lower
margin of this figure by being again stepped up
tothe left, due to the fact that this lock is ar
ranged in the topmost portion `of the cam face 35
plate I8’. Accordingly the two auxiliary push
ers 34 and 35 are shown in Fig. 5 to be accommo
dated in an upwardly extended intermediary
member II’ above the auxiliary pushers 3E, 3'!
and 33, 39 respectively which cooperate with the 40
second and first main needle locks respectively.
For effecting more additional knitting move
ments than previously described by way of exam
ple,` according to the invention, more than two
auxiliary pushers may be used for cooperation 45
by the U-shaped auxiliary lock cam portion 21
with an individual needle, the additional auxil
(line X--X up to line XIII-XIII in Fig. 3). The
needle heels 2' are retracted by the needle lock
cam portion 6 during which movement the con
tour of the needle lock cam portion 8 serves as
a guide for the heels 3’ of the needle jacks which
iary pushers being actuated by corresponding
these heels follow (line XI-XI in Figs. 3 and 4) .
Thereupon, the heels 3’ oi the needle jacks are
gripped and completely retracted by the needle
55 lock cam portion Ill, which at the beginning of
the traverse of the slide was moved into` operative
position, in a known manner, by conjoint move
ment with needle lock cam portion 9, so that the
heels 2’ of the needles enter the corresponding
60 recess in the needle lock cam portion 5. Conse
quently, the needles 2 form long stitches. After
wards the needle lock cam portion 5 retracts the
heels 2' of the needles again into‘their positions
of alignment, whereas auxiliary lock cam portion
65 ZI shifts downwardly and aligns the heels i3"
of the auxiliary pushers I3 not occupying their
operative positions by means of which also the
corresponding needle jacks are depressed again
in the needle bed I to- be locked in their inopera
70 tive positions by the locking members 32. The
triangular knock over cam 3I finally drives the
auxiliary pushers I4 back into initial position.` .
4th patterning possibility-Both, auxiliary
pushers I3 and I4 are in action. The sequence of
75 working operations is the same as .previously ex
15
In this case, the auxiliary lock correlated to
the lower main needle lock, which `may be `called
the second needle lock, is raised to a _higher level
than that of the first auxiliarylock> as thisis in
dicated in Fig. 3 by the set-back above the knock 2,0
over cams 3D, 3|. The corresponding two aux
iliary‘pushers I5 and I6 are guided by the same
intermediary member I I as the auxiliary pushers
auxiliary lock cam portions.
Thus, for exam
ple, the auxiliary bed shown in Fig. 5 may be as
sociated with a double cam slide machine in which 50
with the individual needles three auxiliary push
ers cooperate, the auxiliary pushers accommodat
ed in the lower half of the auxiliary bed cooper
ating with the ñrst main needle lock and the
three auxiliary pushers accommodated in the 55
upper half of the auxiliary bed cooperating With
the second main needle lock of the knitting ma
chine.
`
.
Moreover, it is possible without any other fur
ther provisions to increase, according `to the 60
length of the invention, the individual needles of
flat knitting machines to which the` invention is
applied (Fig. 8) and to transmit the raising and
lowering movements of the intermediary members
I I to the needles 2” (Fig. 6) which in thiscase 65
are adapted to swing about their tips.
`
„
In pearl knitting machines to which the inven
tion is applied (Fig. 7), the needle jacks 3,” as
such may be adapted to carry out the swinging
movementsv or else auxiliary needle jacks 3 may 70
be employed that are pivoted to the needle jacks
3” (Fig. 9) for actuating the needles 2"’.

shape, number or arrangement of parts as shown
and described, all of .which may be varied With 75
