Renewed November 12, 1935
19 Claims. (Ci. 66-135)
This invention relates to a knitting machine acterindicated in which proper individual needle
and speci?cally a machine of the rotary needle shogging may be effected. Speci?c objects of
type in which patterns are produced by wrap
the invention relating particularly to details of
ping of the needles by yarn carrying ?ngers construction and control will be apparent from
the following description read in conjunction 5
5 which may be shogged relatively to the needles.
In an application of Stanley R. Shelmire, Se
with the accompanying drawings in which:
rial No. 623,057, ?led July 18, 1932, there is dis
closed a rotary needle machine in which there
are provided wrap ?ngers carried by a rotating
head and designed to carry wrap yarns‘ selec
tively about needles to produce designs, the wrap
yarns‘ being drawn in loops together with a main
yarn or yarns.
In this machine a given wrap
?nger serves to individually wrap only one par
15 ticular needle. Accordingly in such machine it
is not possible ‘to produce what are known as
shogged patterns in which the same wrap yarn
is used to individually wrap various needles in
different courses. The rotary needle machine is‘
20 preferable to a stationary needle machine be
cause of ease of control of the needle and Wrap
~ ?nger actuating elements, even though it re
quires the wrap yarn supplies to be rotated with
the ?ngers.
There are various ways of producing shogging
in a stationary needle machine to locate a wrap
?nger in cooperative relationship to various dif
ferent needles to produce shogged patterns. As
an illustration of a satisfactory type of mecha
30 nism for producing shogging in a stationary nee
dle machine, there may be cited my Patent
1,892,702, dated January 3, 1933,v which is par
ticularly referred to herein since it illustrates
a type of shogging mechanism which is reliable
35 in operation inasmuch as it effects a de?nite
operative alignment of any one of a number of
wrap ?ngers with various successive needles
within predetermined limits of movement. The
mechanism of said patent for securing accurate
40 alignment of the wrap ?ngers with needles is
utilized in a modi?ed form in the present in
vention in which shogging of a rotating wrap
?nger carrier relatively to a rotating needle
cylinder is produced, so that shogged patterns
45 may be made in the more desirable rotary needle

end a gear ‘I2 driving a pinion I4 carried by a
shaft journalled in a bracket of the frame. The
shaft carrying the pinion I4 is provided with a
lower member of a universal joint I6, the upper
10 member of which is connected with one section
of a two-part splined shaft l8 which at its
upper end is connected through a universal joint
26, similar to l6, to a shaft 22‘ which carries a
pinion 24 meshing with a ring gear 26. The uni
15 versal joints l6 and 20 are of the conventional
type which will maintain the pinions I 4 and 24

?xed bracket 12 so that the pawl is held out of
contact with the teeth when in its retracted
position to which it is urged by the spring 51.
As the lever 54 ismoved clockwise as viewed in
Fig. 5 the pawl 62 will move to the right as 10
shown in Fig. 7 so that it will engage a tooth of
the ‘ratchet 66 as the pin 68 rides oil‘ the cam
18. The cam 10 is provided primarily to nor
mally hold the pawl 62 away from the teeth to
permit reverse movements of the carrier 40.
15
A rod 14 carried by the lever 54 is arranged
to engage a tail portion 16 of a detent 18 mounted
on a ?xed stud 80 carried by the bracket 32 and
urged by a spring 82.to bring its nose into en
bodily movements of translation of the pinion
24 so long as its axis remains parallel with the
20 axis of the pinion l4. It may be noted that the
universal joints together with the splined ar
rangement permit the axes to remain parallel
in spite of the movements of the axis of the gear
24 about the axis of rotation of the needle cyl
25 inder as will be hereafter evident.
‘
\Referring to Fig. 3 it will be noted that the ,
ring gear 26 is carried by the bobbin supporting
plate 28 which carries a bearing ring 30 rotating
on the top of the bracket 32 which when in op
30 erative position forms an integral part of the
machine frame, although it may be tilted as
described in the Shelmire application when the
latch ring is open or independently of said latch
ring, the shaft [8 permitting this to occur. Se
cured to the bobbin plate is a tubular member
34 extending inside an opening in the bracket
32 which provides a bearing for it. The lower
end of member 34 carries the wrap ?nger sup
porting head 36 ‘which is slotted and formed
40 to provide support for wrap ?ngers 38 held there
in in the usual fashion by a spring band. These
wrap ?ngers are actuated as described in the
Shelmire application by means of suitable cams
to cause their lower ends to move outwardly
45. and inwardly between the needles 4 of the needle
circle to produce wrapping, patterning being ob
tained by the selection of needles.
The bracket 32 .is provided with an external
bearing surface concentric with the axis of the
50 wrap ?nger head and the needle cylinder on
which is joumalled a carrier 46‘.
A lateral ex
tension of the carrier 48 provides a journal for
the shaft 22‘ and the pinion 24. By reason of
the concentric mounting of the carrier 40 and
55 the gear 26 it will be seen that the pinion 24
will remain in mesh with said gear irrespective
of the position of the carrier.
At the side of the machine illustrated in Fig. 1
the carrier is provided with an extension 42 to
60 which are secured ratchet plates 46, 48 and 58
illustrated in plan in Figs. 7, 8 and 9 from».which
it will be seen that the teeth 66 and 96 of the
plates 46 and 50 are directed in one direction
while the teeth 84 of plate 418 are directed
in the opposite direction. The carrier 46 is urged
' clockwise, as viewed in plan, by a spring 44.
An extension of the bracket 32 carries a stud
52 on which are joumalled three levers 54, 56
and 58, these levers being provided with exten
70 sions carrying ‘stop screws 59 urged into contact
with an extension of the. frame'by individual
springs 51 which urge the levers 54, 56 and 58
counterclockwise in opposition to actuating mech
75
,
6 which is driven through an intermediate gear
by the driving gear 8 carried by the shaft ID, the
gear 8 being driven by the usual mechanism de
' anism. At its upper end the ?rst of these levers
carries a stud 68 on which .15 joumalled 8- pawl
gagement with teeth 84 of the ratchet plate 48. 20
This detent is provided to hold the ratchet plate
in position during reciprocation at which time
the spring 44 might be insu?icient to hold the
carrier 46 su?iciently rigidly to prevent objec
tionable vibration. The extension 14 fromthe 25
lever 54 serves to trip the detent 18 prior to the‘
engagement of the pawl 62 with the ratchet 46
so that a free forward movement under the
action of the pawl 62 may take place.
Also joumalled upon the stud 80 are detents 30
86 and 88 of different lengths as is evident in
Fig. 9. These detents are arranged to alternately
engage teeth 90 of the ratchet plate 50 to hold
the same in opposition to the e?ort of spring 44.
The detents are yieldingly held in operative en 35
gagement with the teeth 90 by, means of springs
92 reacting between them and a ?xed pin on
the machine frame. It is to be noted that the
angular spacing of the teeth 58 is double the
spacing of the teeth 66. The lengths of pawls 40
86and 88 are such that as they are alternately
tripped the carrier 46 may move backwardly in
steps under the action of the spring 44 through v
the angular spacing of teeth 66 of which more
will be said later.
Members 94 and 96 carried by upper ends of
levers 56 and 58 respectively are designed to
engage the pawls 86 and 88 respectively to trip
them out of engagement with the teeth 98. The
operation is such that the members 94 and 96 .f
are alternately moved so that backward steps of
proper angular amount are produced by the
alternate freeing of the detents 86 and 88 from
the teeth 98.
-
The levers 54, 56 and 58 are engaged respec
tively by the upper ends of levers 6|, 63 and 65
pivoted on a common stud and extending down
wardly adjacent each other and provided at their
lower ends with contact screws 61, 69 and ‘II,
(El)
respectively, located at the same level.
These contact screws are selectively engaged
for the rocking of their corresponding levers
by pattern controlled mechanism of a type gen
erally similar to that illustrated in my Patent
1,805,697, whichmechanism is used in that patent
for the selective actuation of yarn. carrying ?n?
gers. It is, however, of general application as
will be evident from the following description.

Three levers ‘I3, 15 and TI are pivoted side-by

supports secured to the usual pawl carrying arm
19 which is oscillated in the usual fashion by a
cam formed in the gear 8 as indicated in Fig. 2. -

levers under the action of springs 83 are such
that they extend above the level of a guard 8'I

the parts are shown in the positions occupied at
When the lever ‘I9 swings to the left as viewed
in Fig. 1, assuming the position of the mem

‘I3 will be rocked clockwise in view of the fact
thatthe spring 99 is effectively stronger than
any of springs 03. The selection of ‘I3, ‘I5 or
‘II depends upon the particular height of the
lug beneath the follower I03 during this back
position.
An engaging member 99, having a width less
than the width of any of the upturned‘ portions
85 of the levers, is pivoted upon a downwardly
extending arm SI of a bell crank carried by a
?xed pivot which is preferably vertically adjust
able upon the usual post provided to carry the
bobbins of yarn forming the main supply of the

carried by the lever 99 to move the same upward

position, which will be more fully described later,
irrespective of the setup of the pattern chain.
This arm II I is furthermore connected with suit
able elements for restarting the feed of the pat
tern chain in the conventional fashion. Since
the various parts just noted have no particular
bearing upon the present invention they are
not described in further detail. It will be suffi
cient to say that the pattern mechanism is in
all respects similar to that of my prior patent.
The chain I0‘I is provided with either plain
links or links having lugs of three di?erent
heights.
When a link‘without lugs is opposite
the follower I03 the member 09 will occupy a
position directly behind the tail of the lever ‘I3.
While only two pattern chains are indicated, it
vided for controlling the various operations in- .

already referred to. Shogging is desirably pre
vented whenever wrapping is not taking place
although it may be permitted without detrimen

tal effect since at‘ the time when no pattern is
desired the cams normally acting upon the wrap
?ngers are rendered inactive.
' The operation of the shagging mechanism will
be clear from a consideration of what would oc
cur if the needle cylinder and gears I2 and I I
were held stationary and movements were im
parted to the carrier I0. In such case the angu
lar position with respect to the frame of the
machine of the pinion 24 would remain fixed in— 70

order. The parts are so timed that no wrap 15
standpoint of having the needle cylinder and ?ngers are passing through the needle circle when
driving connections stationary, it will be obvi _ shogging is taking place, the shogging in either
ment of the carrier 40 will cause a rotation of
the gear 26 and consequently of the wrap ?n
ous that-the same results will occur when the
needle cylinder is moving if the carrier is stepped
20 about in the same fashion so that the total move
ment of wrap ?ngers in any given time is equal
to the algebraic sum of the rotary movement of
the needle cylinder and the movement due to
the shogging of the carrier 40. Accordingly by

direction taking place during only a small portion
of a revolution of the needle cylinder.
By the above arrangement it will be seen that
a de?nite positioning of the wrap ?ngers relative
to the needles is obtained even though both the
wrap ?ngers and needles are rotating at high
speeds for the production of rotary knitting. It
will be noted that the'successive positions of the .

30 effected by the action of the pawl 62.
The arm
6| is preferably the innermost one as shown so
that its support is quite rigid. The movement
of lever 6| must be fairly accurate particularly in
a ?ne gauge machine although, as will be pointed
35 out later, this pawl does not serve for the accu
rate positioning of .the ?ngers in operative rela
tionship to the needlesibut rather- imparts a slight
. overthrow to the teeth of the ratchet 66; that is,
its throw after engagement with the teeth is
40 slightly greater than the spacing of the teeth but
_ less than twice such spacing. As has already
been indicated, as the arm 56 rocks to advance
the pawl 62 initially it frees the holding pawl ‘I6
from the teeth 84 of the ratchet 66. Thereafter
45 the pawl 62 becomes active to advance the carrier
by engagement with the teeth 66 of the ‘ratchet 66,
It may be pointed out that this advance takes
place in opposition to the spring M5, the detent
‘l6 being provided primarily to prevent such move
50 ments of the carrier 62 during reciprocation as
might occur in spite of the pull of the spring M.
The stroke imparted to pawl 62 is adjusted by ad
_ .iustment of screw 61.
The actual locating of the carrier. 42 in its
55 proper position is e?ected by the detents 86 and
86 which alternately engage the teeth 96 of the
ratchet 56, which teeth have double the angular
spacing corresponding, as pointed out above,
to the angular spacing of theneedles when'the
60 action of the epicyclic gear train is considered.
This, of course, does not mean that the angular
spacing of teeth 46 is equal to the angular spacing
of the needles, the spacing being different de
pending upon the ratio of the pinion 26 to the gear
85 26. By causing the pawl 62 to give a slight over
run to the carrier 40 the spring 44 serves to pull
the carrier back against one or the other of the
chain or any other relatively remote mechanism
needles.
As a result, no extraordinary care need
be taken in providing lugs on the pattern chain
of very de?nite heights.

made in the speci?c embodiment of the invention
without departing from the scope thereof as de
