will first be described.
The chain 8 passes over another
sprocket at the other end of the machine, as
shown in Fig. 1. The chain 8 carries a lug 9
to which a pitman rod I0 is pivotally connected.
' The other end of the pitman rod is attached to
The movable needle bed 2!, hereinafter called
the “split needle bed”, includes a stationary bed
portion 26 on which the needle sections 22 and
23 and the relatively ?xed sections 24‘ are mov
a sliding sleeve member H which is slidably
10 mounted upon a ?xed longitudinal shaft l2. The
sleeve H is provided with a yoke I3 which is
connected by longitudinal members l4 and [4’
to the carriages 2 and 3. Reciprocating motion
of the carriages over the bed thus takes place
15 when the chain .8 is continuously driven. It is
to be understood that the carriages 2 and 3 slide
_in keyways formed in longitudinal members I5
and I6 and actuate the needles, such as the nee
dle H, by engaging the needle butts.
.
Details of construction of the carriages need
20
not be recited herein since any of the normal or
usual constructions may be employed.
As shown
in Fig. 6, for example, each carriage may be provided with a pick-up 18 adapted to pick up the
25 thread guide l9 which is normally left near the
end of a needle bed while the carriage itself trav
els to a point considerably beyond the needle bed.
As shown in the drawings, the knitting ma
chine may have two opposing needle beds, such
30 as those generally indicated at 20 and 2|. Either
or both of these beds may be provided with suit
able racking mechanism. One of said needle
beds, however, is provided with a plurality of sep
. arate needle sections in accordance with this in
35 vention.
‘
Tmnsposing means
In the drawings the needle bed 2| is
shown provided with pairs of needle sections, such
as the needle sections 22 and 23, each pair being
separated from an adjoining pair, such as needle
sections 22' and 23', by a relatively ?xed needle
bed portion, indicated at 24. In the drawings it
is seen that the movable needle sections 22 and
23 are each capable of holding three needles
whereas the stationary needle sections 24 carry
four needles. Obviously, the number of needles
45 carried by .each of the sections, whether movable
or stationary, may be varied at wil1.-'By the
term “movable needle section” as used hereinafter,
reference will be made to a needle section which
is capable of moving out of the plane of the
501 needle bed.
It is to be understood that where reference is
vmade to stationary needle sections, such as sec
tions 24, the term is used in a relative sense only
ably carried. Each of the split needle sections,
such as the section 23, may be made in accord 10
ance with the-showings of Fig. 16 and includes
a body or shank 21 which is appreciably longer
than the body of the stationary needle sections
24. Each needle section is provided with longi
tudinal slots 28 adapted to slidably receive needles 15
which are then retained in the needle section by
means of a retainer 29 which is fastened to the
body of the needle section by a machine screw
after the needles have been inserted in the slots
28. The upper end of the needle section 23 is 20
also provided with the hook portions 30. Onv
the lower surface of the needle section a trans
versely extending recess 3! is formed, this re
ccss being adapted to clearupstanding butts of
another needle section during transposition of 25
said sections. The shank of the needle sections
is also provided with a semi-circular transverse
recess .32 adapted to cooperatively engage a semi
circular bead 33 formed in the bed 26. The lower
end of each split n'eedle section is‘provided with 30
an upwardly and forwardly inclined face 34
adapted to rest against an upwardly and for
wardly inclined face 36 formed in the ‘edge of
the bed 26, as shown in Figs. 6 and 12.
'The lower shanks of the movable needle sec
tions extend downwardly beyond the ?xed lon
gitudinally extending guide members 15. Below
the guide members I5 is a housing 35 which en
closes a transporting mechanism, this mechanism
including longitudinally disposed members 31 and
38 slidable within longitudinal grooves formed in
stationary portions of’ the machine. These mem
40
bers 31 and 38 are connected to spacing members
39 and 39', which members 39 and 39' are spaced
a distance very slightly in excess of the width of .
a single split needle section, such as a section 23.
The members 31, 38 and 39 form a reciprocable
carriage which moves longitudinally of the ma
chine. The spacing members 39 extend down
wardlyso as to be capable of sliding over the 50
upper surfaces of the shanks of the split needle
sections when said needle sections are resting
upon the bed 26. Mounted upon the carriage
formed of the members 31, 38 and 39 is a cam
7 since the sections 24 may be movable within the
shaft 40, said cam shaft being mounted in suit 55
plane of the needle bed, as during a racking o'p- _

riage. One end of said cam shaft 40 carries a
Means are provided for transposing needle sec
tions 22 and 23 so that their relative positions
with respect to adjacent stationary sections are
60 changed. Such transposing means are generally
indicated at 25. The machine of this invention
also includes trip means for energizing the trans
' posing means and such trip means are more par
ticularly shown in Figs. 3 and 4.
Means are also
provided for controlling and timing the operation
of the transposing means and such controlling
and timing elements are more particularly shown
in Fig. 2. Moreover, means are provided for
varying the tension on the fabric in accordance
70 with the progress of the knitting operation and
75
spur gear 42. The opposite end is provided with
a double acting cam 43._
The cam shaft 40 is provided with cams 44 60
adapted to move into the spaces between adja
cent members 39 and 39’. When the cams 44 are
in completely depressed position, illustrated in
Fig. 11, they contact the upper surface of the split
needle sections 22 and 23.
-
,
Positioned below the needle sections is a shaft
50 to which cams 5| and 52 are keyed. These
cams are'spaced apart a required distance by
means of spacing sleeves 53. The shaft 50 is also
mounted in suitable bearings and is provided with 70
a gear 54 at one end, the opposite end being pro
particularly in accordance with the transposition
vided with another double acting cam 55, which

ing means are. more speci?cally shown in Figs.
2, 3 and 6. In order to facilitate understanding

from the plane of the sector cam 52 so as to press
tion with the inclined face 35 of the bed 26. .
In this manner the threads held by the needles
against an adjoining needle section 22 when the
sector 52 is engaged in the groove of a needle
segment 23, as illustrated in Fig. 9.

Rotation, of the cam shaft 40 and the shaft 52
is obtained in any suitable manner. As shown in
Fig. 5, the gears 22 and 54 are in engagement
with a gear mounted upon a stud shaft til, this
10 stud shaft being driven through a spiral gear
mounted on said stud shaft, the spiral gear being
in engagement with another spiral gear 52 mount
ed upon a spindle 59. The spindle 59 is driven in
any suitable manner from a regulatable source
15 of power. For purposes of illustration, it is shown
that a sprocket 62 is carried by the spindle 59,
this sprocket being in operative. engagement as
by means of a chain (it with a sprocket E52 mount~
ed upon a driven member 33, which driven mem
20 ber is shown journaled upon the drive shaft 2..
During operation of the transposing mecha
nism, the shafts 22 and 50 reciprocate. Recipro
cation is imparted to these shafts by reason of
the cams“ 23 and 55, the opposing faces of each
25 cam passing between ?xed restraining rollers,
such as the rollers 32 and 65. The sequence of
operations which takes place will be understood
from an examination of Figs. '7 to 12 inclusive.
'
_As shown in Fig. 7, the needle sections '22 and
‘so 23 are aligned directly on the bed 26 with the
needle section 22 to the left of the needle sec
tion 23. Partial rotation of the shafts 22 and
50 now takes place and simultaneously the car
' .35
riage, composed of the members 33 and longi
tudinal members 2'7 and, 38, moves to the left
while shaft 50 moves to the right and also partly
rotates. Direction-of longitudinal movement is
indicated by the arrows and continues until the
position shown in Fig. 8 is reached. It will now
be seen that the member 22 is directly beneath
the space to the side of member 39. The cam 52
enters the groove 52 formed in the lower surface
of needle section 23 while cam 55 begins to raise
tion 22 to‘ move over section 23 without entan
gling the threads. Attention is called to the fact
that in the machine illustrated the movable nee
dle sections are loosely retained in the bed and
are virtually not positively connected (as by 10
levers or gears) to other elements, the transposi
tion being effected by a selective engagement of
cams with the needle sections.
‘
The movementv of the shaft 20 toward the right
and the movement of the shaft 52 toward the 15
left, as shown in Fig. 10, is continued until needle
section 22 has completely passed over needle sec1
tion 23, whereupon the rotation of the shafts 23
and 52 causes the cams M to press needle section
23 down onto the bed 22. Section 23 is now re 20
leased by cam 52 and it will be seen that needle
section '22 is now to the right of needle section 23
and not to the left of said section as was the
case originally. After the needle sections 23 and
22 are firmly placed upon" the bed of the ma 25
chine in their now transposed positions, the
shaft 130 moves to the left to some extent, there
by permitting the cam 22 to hold both of the sec
tions 22 and 23 down against the bed of the ma
30
‘chine.
It is to be understood that the transposition
above described takes place while the knitting
carriages 2 and 3 are at the end of a stroke and
away from the needle section of ‘the machine.
The entire operation takes place very quickly, occupying only that period of time which is re
quired for the lug 9 to travel around one-half of
the circumference of the sprocket on which the .
chain ll is held.
-
,
The transposing operation described is per
This operation is continued until the stage
shown in Fig. 9 is reached. It will beseen that
needle section 22 has now been lifted into the
space immediately to the side of the member 39
while needle section 23 is restrained by reason of
cam 52. Further rotationpf the shafts 20 and 52
is“ accompanied by an opposite longitudinal mo
tion of these shafts, cam shaft 20 moving toward
the right whereas shaft 50 moves to the left.
Needle section 22 is retained within the space to
the'sicle of member 39 and is moved by the car
riage containing such members 39 over and above
needle member 23. which is held ?rmly by the
The needle member 22 is re
tained in this raised position by reason of the
60 fact that the tip of such needle member and the
needles contained therein are in engagement
with the fabric. Fig..14, for example, illustrates

The transposing operation described herein
above produces a fabric having a- cable stitch of
the character illustrated in Fig. 15. The normal,
substantially stationary needle sections 22 form
the normal knitted panels ?ll but the split needle 50
sections form the cable stitch shown in Fig. 15
between the plain sections. Attention is called
to the fact that true overlapping occurs between
the stitches 62 and those shown at w/so that it
is possible to insert a pencil, ?nger or other small 55
object beneath the overlappingstitches. It is to
be understood that instead of using but two mov
able split needle sections, three of such sections
may be used and a braided effect or a three layer
rope or cable effect may be simultaneously ob 60
tained. Obviously, the longitudinal distance
separating points at which the stitched sections
68 and 69 cross each other may be varied.

on one arm 14 of a yoke extending from a rocker
shaft ‘I5. The rocker shaft is oscillated in a
usual manner by reason of contact made between
a cam follower, carried by the sliding member I I,
and cams ‘I6, carried by the rocker shaft ‘I5.
Similar cam follower and cam means are em
ployed on the well known Dubied knitting ma
10 chines.
The pawl ‘I3 is yieldingly engageable
with the ratchet ‘II by means of suitable spring
suspension.

chain 12 carries adjustably posi
blocks 18 and ‘I9. Opposing bell
crank levers 80 and 8| are mounted upon rotat
able' studs 82 and 83, these bell crank levers be
ing provided with cam ?ngers provided with in
clined faces adapted to contact with the inclined
faces of the(cam blocks ‘I8 and ‘I9. The lower
ends of the bell crank levers 80 and 8| are con
nected by means of links 84 and 85 to cam seg
ments 88 and 81 respectively.
Mounted upon the rocker shaft 10 are ratchet
segments 88 and 89 and a crank 90. Cooperating
with the ratchet segments 88 and 89 are cam
‘faced pawls SI and 92 pivoted on an arm 74' of
the yoke keyed onto the oscillating shaft ‘I5.
30 In neutral position, i. e., when the machine is
25
knitting in the customary manner, the two cam
segments 88 and 87 are separated apart in oppo
site‘ directions and bear against the faces of the
cam pawls SH and 92, maintaining such pawls
out of engagement with the ratchet segments 88
and 39. The cam-faced pawls 9i and 92 are
yieldably urged against such cam segments 86 and
87 by means of springs and move up and down by
(If)
reason of the oscillation imparted to the yoke
‘Iii’ by the oscillating shaft "I5.
When a cam block ‘I9 raises a cam finger
mounted upon the stud 83, inward motion is im
parted to the link 85 and since this link 85 is
connected to the cam 80, such cam moves toward
the right, permitting the cam-faced pawl 93 to
engage ratchet segment 08 so that upon the
next oscillation of the ‘shaft ‘l5, the rocker shaft
I0 is partially rotated. Partial rotation of such
shaft causes partial rotation of the crank 90
55) and such crank then exerts a pull on a lever 00
which sets a trip mechanism into position.
The lever 90 is pivotally connected to a bell
crank 95 mounted upon a rocker shaft 96. This
- rocker shaft carries a bell crank 91, one arm
of the crank forming a trigger ?nger 98.
The
other arm of the bell crank 91 is attached to a
rod 99 and the lower end of such rod is attached
to the arm of a- bell crank I00 (see Figs. 3 and 4) .
The end of the crank I00 is connected by means
60 of a link IM to a crank I02 carried by a rocker
shaft I03, this rocker shaft carrying a trigger,
generally indicated at I04, the trigger being keyed
to the shaft I03 but yieldably, longitudinally
movable thereon and normally maintained at one
end of the shaft I03 by means of a spring I05.
The drive shaft 4 is provided with a clutch in
cluding a driving member I06 provided with a
circumferential lip having notches I01 formed
on the internal surface of the lip. The driven
member 63 comprises a disc I08 provided with a
radial slide, a dog I09 being slidably carried in
such slide and outwardly urged by means of a
spring. The dog is adapted to engage with the
notches I01 when the trigger I04 is pivoted out
75 wardly into the position shown in Fig. 3. The
trigger I04 is provided with an inclined face H0
capable of engaging with the protruding portion
of the dog I09 so as to'raise the dog out of con
tact with the notches I01.
In the event trigger I 04 is moved into sub
stantial contact with the face of the disc I08, said
disc rotating in the direction of the arrow indi
cated in Fig.4, the inclined face I III of the trigger
I04 will raise the dog I09 out of contact with
the notches I01, thereby disengaging the clutch 10
and stopping the transposition mechanism
driven by the sprocket 62. The spring I05 will
yield slightly under the impact of the dog upon
the face IIO.
When the trip arm 98 is moved into position
(by reason of pawl 9| engaging ratchet segment
88 and partially rotating rocker shaft 10 and
crank 90), then upon the next movement of the
carriage 2 the trip arm 98 is struck by the trip
pin I I2_ mounted on said carriage and the rod 99 20
is depressed, causing rocker shaft I03 to swing
the trigger I04 outwardly, releasing the dog I09
and causing the clutch to engage. The bell
crank I00 is normally urged upwardly, however,
by means of a spring I I3 and in order to prevent
the trigger I04 from immediately snapping back
onto the face of the disc I08, said disc I08 is pro
vided with a ?ange I08’ extending outwardly
from said disc for approximately one-half of the
circumference thereof. This ?ange I08’ engages 30
with an extension I04’ of the trigger (Fig. 3),
keeping said trigger out of contact with the face
of the disc I08 for about one-half of the revo
lution- of such disc. In the embodiment of the
invention herein described, one rotation of the
drive shaft 4 and one rotation of the sprocket 02
causes the performance of a complete transposi
tion cycle in the mechanism 25.
In order to again oscillate the shaft 96 so as
to lower the trip arm 98 out of engaging posi 40
tion with the trip pin- N2, the secondary cam
block l9 raises a cam ?nger mounted upon the
rocker shaft 82 and the rocking motion thus pro
duced in the arm 80 swings the cam segment 81
toward the left, permitting the cam-faced pawl
82 to engage with the ratchet segment 89, pull
ing said segmentdownwardly. This imparts par
tial rotation to the crank 90 which partially
rotates the rocker shaft 98 to lower the trigger
50
arm 90 out of the path of the trip pin I I2.
Fabric tensioning means
As the knitting operation proceeds, the fabric,
generally indicated at II5 (Fig. 6) passes down
wardly into contact with a roller I I6, which roller
is preferably provided with a yielding surface.
The roller is mounted upon a shaft Ill and the
fabric is maintained in pressure contact with the
roller IIO by means of a cooperating roller II8
mounted upon a shaft held by means of a weighted 60
lever II9 pivoted at I20 and provided with ad
justable weights I2I. The fabric then may pass
over another roller I22 and ?nally fall into a
suitable container. The shaft III on which the
roller H6 is mounted, is driven‘ in timed relation
to the travel of the carriage over the needle bed.
The shaft III is driven by means of a sprocket
mounted thereon and a chain I23 (see Fig. 3).
The chain passes over a sprocket I24 pinned on a
shaft I25, said shaft also carrying a ratchet wheel 70
I26. The bell crank lever I00 may be journaled
on the shaft. I 25.
The ratchet I26 is operated by means of a cam
I30 carried upon the drive shaft 4, the cam co
operating with a roller carried by one end of a 75

which is urged against the ratchet 826 by means (Fig. 1). These cam sections are for the purpose
of the spring I34 attached to the bell crank Iltl of moving the needles into the position shown in
Fig. 13, the needle being advanced only suf

Although a complete knitting machine has been

It will'l'be readily seen by those skilled in”the
art that the machine of this invention includes a
number of novel arrangements of elements where~
55 by highly desirable and novel effects can be at
tained. It is to be understood that the various
operations described and the various units illus
trated and referred to operate in timed relation
to one another. The oscillation of the rocker
60 shaft I5 is synchronized with the passage of the
carriages over the needle bed. The setting of the
trip ?nger 98 takes place at a desired point in
the travel of the carriages and while the car
riages are moving away toward one end of the
machine. On the return stroke, the trip pin M2
engages the trip arm 93, causing the transposition
of the needle sections to take place while the
carriages are away from the needle bed and re
versing their direction of travel. All of theoper
70 ations and units are capable of taking place
rapidly so that the knitting machine may be oper
ated in’ a continuous, unentrapped manner, pro
