The mechanism just referred to is perfectly
` adapted for the purpose of producingselective
plating and reverse plating, but unless> the num;
‘ ber of butts on the jacks is increased ,tov `an
objectionable extent which would not only take
` up an undue amount `’of space, but which would
give rise to- ’objectionable lateral thrust‘on the
jacks, there is aA deiinite limit to the character

Fig. >l is a diagrammatic vertical section taken
on i‘ the plane indicated at I--l in Fig. 3 through
needles >and `'other associated parts. _The needles
are of the usual latch type land are provided with
maintainedjinproper position within the needle
slots without being carried outwardly. In order
to provide for _the deñection _of the upper Vends of
the needles the upper end of each slot is deepened
to provide a shoulder `lll above which Athe upper 30
endof the needle may be deñected inwardly, the
deiiection'being limited by engagement ofV the

55 needle, jack andl „ associated cams;
20
butts I0 and Vshoulder-s I2 located, as illustrated,
above -the butts. In order` to producer reverse
plating, the upper ends of the needles are adapted
toY be ?lexedinwardly, while at the sameV time,> as
is desirable, the lower ends of kthe needles are "

moved downwardly by engagement of a cam with
its butt so that both of the spring bands may be 55

2,134,479
above the projection 26 as indicated for example
in Fig. 9.
Rotating outside the needle circle in the usual
fashion is the sinker dial 28 in which the sinkers
30 are guided for their usual inward and outward
movements between the needles by suitable cams,
this action occurring in conventional fashion.
Slidable in suitable slots in the sinker dial are
jacks 32 which are aligned with the needle slots
10 so that each of them on its inward'movement
may engage the shoulder I1 of a presser if the
presser occupies its raised position. In this case
the jack may move the presser suii‘lciently in
wardly to cause the upper end of the needle to
be deflected inwardly and thus produce reverse
plating. However, if the presser is in its lower
position, then inward movement of the jack cor
responding thereto will move above the shoulder
|1 and will be ineffective to deflect the needle.
20 Each jack is provided with a plurality of butts
34 in the present embodiment of the invention,
although, as will be described later, it is some
times necessary to provide only a single butt, the
butts not being used in general for selectivity in
25 the production of designs. The various jacks are
lightly held inwardly by the use of a spring band
36 which, however, does not exert upon them
such force as would cause them to deflect the
needles.
30
Located in the needle slots below the needles
are intermediate jacks 38 provided with butts 40,
While below these intermediate jacks are located
lower tilting jacks 42 whose inner edges are so
formed as to provide a pivot 44 about which, as a
35 horizontal axis, the jacks may rock. At their
lower ends the jacks 42 are provided with shoul
ders 46 adapted to engage cams, as will be here
inafter more fully pointed out. The jacks are
also provided below their pivots with butts 48
40 which may be selectively arranged for the pur
pose of producing patterns.
The jacks may be
supplied, for example, containing a full comple
ment of butts which may be selectively broken
out in order to provide the necessary setup for a
45 desired pattern.
Referring to Fig. 3, there is disclosed the lay
out of cams arranged to act upon the needles,
jacks 32, the butts of the pressers, and the inter
mediate and lower jacks 38 and 42. The needle
50 stitch cams are of the usual variety and comprise
the upper center cam 50 and the usual stitch
drawing cams 52 and 54, the former of which
serves to draw the needles downwardly during
rotary knitting.
Cooperating with the lower jacks there are an
55
upper cam 56 designed to rock the lower ends of
' the jacks outwardly, and a series of lower cams
60 and 62 designed to rock the lower ends of the
jacks inwardly. All of these cams are formed as
60 levers and will be referred to hereafter. The
lowermost of the cams designed to rock the
jacks inwardly is designated differently from the
others, since it performs a somewhat different
function.
In advance of the cams 60 there is located a
fixed cam 58 which is designed to engage the
shoulders 46 on the lower jacks and cause them
to rise to a predetermined level before they reach
the location of the cams 00. This action insures
70 a proper vertical alignment between the butts 0n
the jacks and the various corresponding cams 60.
65
There is also provided in a position following the
cams 60 a cam 66 having an upward slope 64 on
which the shoulder v46 of such of the jacks 42
75 as have their lower ends extending outwardly
may ride whereby such jacks will be raised. A
slope 68 provided on the cam 66 serves to rock
the lower ends of the jacks inwardly and thus
disengage them from the top level of the cam 66.
A guard cam 10 is provided to prevent possibility Ul
of damage to the jacks during reciprocation and
limit their downward movements.
A cam 12 is provided designed to engage the
butts 22 of raised pressers so as to depress all of
the press-ers at its position. This is to prepare
the pressers for a subsequent selection.
Cams 14 and 16 are respectively designed to
raise and vlower needles by engagement with their
butts |0 ifor purposes which will hereafter become
apparent.
The lower action of cam 16 is con
tinued by the usual guard cam 18. A ring of
cams indicated at 8| serves to maintain the inter
mediate jacks within their slots. A cam face 80
on the lower portion of this series is adapted to
engage the butts 40 of the intermediate jacks to
lower them and with them the lower jacks 42.
Levers 82 and 84 are provided to act upon the
butts of the horizontal sliding jacks 32. A cam
86 is provided to raise the-needles to a desired
level. It may be noted that the loops on selected
needles clear the latches just prior to cam 14
and the loops on unselected needles clear the
latches thereof at cam 54,
The layout of cams having been described,
there will now be referred to their controlling 30
means. The cams 82 and 84 have identical oper
ating devices indicated in Fig. 4. These cams are
formed on the ends of levers which are pivoted
at 88 and are provided with tails 90 carrying cam
surfaces 93 held in engagement with actuating 35
ends of levers 94 by springs 92. Each of the
levers 94 is provided with an elongated slot 06
receiving a vertical pin 98 and is urged by an
individual spring |02 into engagement with an
adjustable fixed stop screw |00. By this arrange
ment, as will be obvious, there is provided a fine
adjustment of the position of the levers 94 and
hence of the positions of the cam ends 82 and
84. Very fine adjustment is here necessary, in
View of the fact that such adjustment determines
the extent to which ñne gauge needles may be
deflected inwardly, which should be to contact
with the bottom of the needle slot as mentioned
above without strain on the needles by too much
deflection. Each ofr the levers 94 is connected by 50
a link |04 to a lever |06.
The levers |06 are
secured to nested vertically extending shafts
which carry at their lower ends cam following
levers |08 engageable under the action of springs
|02 with suitable controlling cams ||0 on the
main cam drum |||, which is stepped about
under chain control during the operation of the
machine in the usual fashion. The butts of the
jacks 32 lie approximately in the circle indicated
at ||2, while the needle circle is indicated, for 60
comparison, at ||4.
The cams 14 and 16 are
moved radially together and are carried by a
sliding plunger ||6 guided in a ñxed portion of
the machine and urged outwardly by a spring
IIB into engagement with an adjustable stop
screw |20 carried by the end of a lever |22 which
is urged counterclockwise, as viewed in plan, by
a spring |24 stronger than the spring | I8.
The cam 12 is carried by a similar plunger |26
urged outwardly by a spring |28. The plunger 70
|26 is moved inwardly at the proper time by a
clockwise movement of a cam |30 on a lever |32.
The levers |22 and |32 are mounted upon verti
cally extending nested shafts which, at their
lower ends, carry cam following levers |36 and 75

‘
The, operations involved'inïproducing normal
and reverse plating bythe mechanism just de
scribed will be readily understood from a consid
eration primarily of Figs; 1, 3, 7, 8 and 9. In Fig.
`3 there are indicated in dotted lines the paths ofr
Y the cam 56 andthe jack consequently rides up
wardly due to the'action of the cam 5B into posi
tion" wherein its butts are aligned with the vari
ous ‘cams 60.
VIn this case, however, none ' of
the cams will engage any of the butts and there
65
fore as‘the jack approaches the _cam 64 its shoul
derwill engage the ca1n`and will `follow the path
characteristic parts of the various elements as . indicated at Í. As the lower jack moves-upward- ,
sociated
with the needles in the needle slotsìand. ` ly, the intermediate jack is pushed upwardly so 70
70
the needles themselves. For` example, at a and b
there are indicated the` alternative 'paths lof the
«needle butts. At c- and d there are indicatedthe
alternative paths Vof the butts .22 of the pressers
751 I6. At e and f there A‘are indicated 'the alternative
that its f butt follows the path h._ As `the in
termediate 'jack`- approaches its maximum height,
it engagesthe needle and moves it upwardly to
such extent that its butt will> engage-the cam
'I4 and consequently follow the path indicated 75.

at b.
2,134,479
Prior to this, if ' the presser had been in
upper‘position, it would be depressed by the
action of the cam l2. As the needle rises as in
dicated at b, its shoulder I2 will'engage the press
er, moving it upwardly so that its butt will fol
low the pathindicated at d, with the shoulder
il now aligned with the jack 32. Immediately
after raising the presser, the needle is depressed
by the cam 'I6 and later by the guard cam T8,
whereupon it passes through the knitting cams
inthe conventional wave. As the stitch is be
ing drawn, the needle will now be deflected by
reason of the engagement of the shoulder I'l of
the presser by the jack 32. In view of the for
15 mation of the presser, the needle is engaged both
above and below the shoulder I4, and consequent
ly deñection takes place without any tendency
of the lower end of the needle to move outward
ly from the slot. The deflection of the needle
during the stitch drawing operation serves to
effect reverse plating in the well known fashion.
From the above it will be obvious that the
proper preselection of elements insures the pro
duction of eithernormal or reverse plating in
25 the next stitch drawing operation. It is to be
noted that the action ofthe cams 60 is some
what negative in the sense that reverse plating
is effected when none of the cams engages a
lower jack.
30
`
It is frequently desirable to interrupt the for
mation of patterns in order to knit what is known
as a plain sole.
If the sole needles are asso
ciated with jacks provided with butts in align
ment with the cam 62, then if this camis caused
to be continuously in operative position during
the formation of the foot portion of the stock
ing, normal plated knitting will be effected on
the sole needles. At the same time, selective
actuation of the jacks associated with instep
40 needles may proceed as in the knitting of the
leg, the jacks associated with these latter nee
dies having the butts capable of cooperating with
the cam t2 removed.
Alternatively the Yproduction or non-production
45 of reverse plating may be controlled by a selec
tion of cams 82 and 84 cooperating with a pre
determined arrangement of butts 34 on the jacks
32. Usually, however, both of these cams may
be continuously operated or,` if desired, only one
need be provided. They may, however, be used
not only for producing a plain sole or similar
wide band of normal plating, but may be asso
ciated with a predetermined setup of butts on
the» jacks and selectively controlled to effect the
65 production of a checked design on which may
be superimposed the more elaborate patterns
effected by control of the lower jacks. In view
of the fact that the control of the lower jacks
is primarily depended upon for production of
602 patterns, it is usually unnecessary to provide any
large number of butts 34.
However, if desired,
more than two of these may be used, the selec
tion then proceeding along the lines of my prior
application referred to above in addition to that
accomplished through the medium of the lower
jacks.
The various cams l2, 14, 16, 82 and 84 are
made movable primarily for withdrawal dur
ing heel and toe knitting and also for purposes
.7G of leveling and transfer, the movability of cams
82 and 3i! being provided to prevent the deflec
tion of needles during the transfer» operation in
addition to their movability, if desired, for selec
tivity.
L
It will be observed from the above that there
is 'provided a method and machine whereby selec
tivity of a high degree may be attained for the
production of very elaborate patterns. This is
due not only to the provision of multiple butt
jacks 42,»but also to the groupings of the cams
60 whereby any one of a plurality of groups may
be 'rendered active to control the jacks. Addi
tionally, as pointed out above, control may be
achieved through selective action of cams upon
the jacks 32l which actuate the pressers.
The 10
trick-wheel, furthermore, need not be stepped
about uniformly, but an irregular motion may
be imparted thereto by the proper setup of the
chain |52. An enormous variety of patterns can
thus be , achieved with a compact patterning 15
means of simple form so that setup for the pro
duction of any desired pattern is readily effected.
It will be clear that Various changes in the
specific embodiment of the invention may be
made without departing from the scope thereof 20
as deñned in the following claims.
