Improvements in Knitting Machines and Knitted Fabrics.
I, JAMES YATE JOHNSON, of 47, Lincoln's Inn Fields, in the County of London,
Gentleman, do hereby declare the nature of this invention (which has been
communicated to me from abroad by Robert Walter Scott and Louis Napoleon
Devon Williams, both of No. 2077, East Cumberland Street, in the City and
County of Philadelphia, State of Pennsylvania, United States of America,
Manufacturers of Knitting Machinery) to be as follows:-
This invention relates to knitting machines for the production of striped
fabrics, by the use of continuous knitting yarns, the yarn, or yarns, not in use,
floating on the inner side of the tube of fabric from stripe to stripe.
In such machines a series of yarn guides is employed there being one guide
for each of the yarns used, and these guides are controlled by mechanism
whereby the foed end of either guide can be moved into, or out of, feeding
relation to the needles, so that any desired yarn can be fed to the needles through-
out as many courses as may be desired.
The objects of the present invention are
First. To provide for the ready insertion, or removal, of the needle cylinder,
so that, after a certain length of striped tube has been knitted, the needle
cylinder, with the knitted tube upon the needles, can be removed for application
to a separate machine which adds to the said tube a knitted web adapted to formi
the foot of a stocking, of which the striped tube constitutes the leg.
Second. To produce a closely knitted web, or a slack stitch knitted web, as
desired.
Third. To slacken the stitches of the web at, and near, the point where the
yarn changes, and thereby prevent straining, cutting, or tearing, of the web,
which might otherwise result from the presence of double yarn stitches, in
certain wales, wherever a change of yarn is made.
Fourth. To prevent engagement of the floating yarn, or yarns, by the needles,
and to insure the prompt engagement of the new yarn whenever a change takes
place; and
Fifth. To provide simple and efficient mechanism for automatically operating
the thread guides and other parts of the machine.
The machine has a fixed table, or bed, with depending bearings for a driving
shaft, which is under control of a clutch, and the latter can be moved by means
of a shipper lever so as to arrest the operation of the machine in the manner
hereinafter set forth.
The driving shaft has secured to it a bevel wheel which engages with a bevel
pinion secured to, or forming part of, a needle cylinder carrier, having an
annular flange which extends up into the needle cylinder is split at one, or
more points, and is tapered internally for the action of an annular wedge which
has a hollow threaded stem extending down below the carrier and threaded for

page_text: engagement with a nut which bears upon the underside of the said carrier and
has, at its lower end, an annular flange by which it can be readily manipulated
so as to draw down the wedge and thereby expand the split and tapered ring
in order to firmly clutch the needle cylinder to the carrier, or the nut may be
turned in the reverse direction so as to permit the wedge to rise and thus permit
contraction of the ring until its hold upon the needle cylinder is released and
the latter with its needles can be removed from the carrier and from the annular
cam box which surrounds the lower portion of the needle cylinder and is secured
in any appropriate manner to the table, or bed, of the machine.
Mounted upon the upper portion of the needle cylinder is a web holder ring
carrying a series of radially guided web holders which, as the needle cylinder
rotates, are actuated by means of cams upon a web holder cam ring surmounting
and surrounding the web holder ring, the said cam ring being prevented from
rotating with the needle cylinder by reason of the engagement of one, or other
of a pair of lugs on the cam ring with a fixed arm, or bracket, projecting upwardly
from the annular cam box, a certain amount of play being permitted between
the lugs in order that the web holder operating cam will assume its proper
relation to the knitting cams whether the needle cylinder is being rotated to the
right or to the left.
On the driving shaft is a grooved cam which engages. with a pin projecting
from the lower end of a primary ratchet lever, the latter being hung so as to be
free to swing upon a rock shaft mounted in suitable bearings in the table, or
bed, of the machine and in a longitudinally projecting arm, or bracket, of the
said table, or bed.
The primary ratchet lever carries a pivoted pawl which is acted upon by a
spring whereby it is held in engagement with the teeth of a ratchet wheel
secured to one end of a primary pattern drum, the latter being mounted so as to
be free to turn upon a shaft, or spindle, secured to, and projecting from, the table,
or bed, of the machine, a handle at the outer end of the hub of the drum serving
as a means whereby the latter can be rotated independently of the pawl and
ratchet mechanism described.
Backward motion of the primary pattern drum is normally prevented by
means of a retainer pawl, or detent, carried by a lever which is hung to a pin
carried by a bracket secured to, and projecting upwardly from, the longitudinal
arm on the fixed table, or bed, of the machine.
By depressing the outer end of the said lever, however, the retaining pawl, or
detent, can be withdrawn from engagement with the teeth of the ratchet wheel
on the primary pattern drum and, at the same time, and by the same action,
the spring pawl will also be withdrawn from engagement with the said teeth
owing to the fact that a set screw on the lever strikes a projecting tail of the
pawl and thereby effects the retraction of the latter.
The outer end of the lever may be held in the depressed position for any
desired length of time by swinging into engagement therewith a pivoted arm,
or catch, hung to the bracket before referred to.
Secured to the driving shaft is a cam which acts upon an enlargement, or
shoe, at the lower end of a secondary ratchet lever which is loosely hung upon
the shaft, or spindle, of the primary pattern drum, and carries at its upper end
a pawl adapted to engage with a ratchet wheel secured to the shaft of a secondary
pattern drum which is carried by a yoke, or frame, having trunnions mounted
in brackets on the fixed table, or bed."
The pawl of the secondary ratchet lever is acted upon by a spring which
tends to pull the toothed end of the pawl into engagement with the teeth of the
ratchet wheel of the secondary pattern drum, this movement being restricted by
contact of a projecting finger of the pawl with a pin, or stud, projecting from
one of the brackets in which the shaft of the said drum is mounted.
The upper end of the secondary ratchet lever is drawn rearwardly by the action
of a spring but this movement is normally restricted a pin on the lever coming

page_text: in contact with the bent end of a retainer arm which is secured to the inner end
of the rock-shaft before referred to, so that so long as the movement of the
secondary ratchet lever is thus restricted it will not move the ratchet wheel of
the secondary pattern drum, the restricted movement being less than the length
of a tooth of the said wheel. When, however, the bent end of the retainer
arm is raised so as to free the pin from its control, the upper arm of the secondary
ratchet lever and its pawl will be drawn forward under the action of the spring
so that the pawl will engage a fresh tooth of the ratchet wheel of the secondary
pattern drum and when the secondary ratchet lever is actuated by its cam, will
move the said ratchet wheel and also the secondary pattern drum to the extent
of one tooth.
The secondary pattern drum carries projecting studs which act upon yarn
guiding levers hung to a suitable transverse pin on the frame which carries the
drum, the outer ends of these levers having eyes for the guidance of the knitting
yarns and the levers being so disposed in respect to the needles of the machine
that when the outer end of a lever is depressed its yarn guiding eye will be in
position to feed the yarn to the needles of the cylinder, but when the said
outer end of the lever is raised its yarn will be fed over the tops of the needles
and will not engage the same, hence by a proper manipulation of the levers
due to a proper disposal of the studs upon the secondary pattern drum, any
desired one of the levers may be caused to feed its yarn to the needles, the other
yarns floating on the inside of the web ready to be likewise brought into action
when required, so that the striping of the web by the feeding of different
coloured yarns successively to the needles, and the change from one color to
another, can be instantly effected without any stoppage in the rotation of the
needle cylinder.
An arm projects forwardly from one side of the frame which carries the
secondary pattern drum and this arm has, at its outer end, a spindle to which
is secured a hub having a series of projecting blades which fit between the
forward ends of the yarn guiding levers, the shaft, or spindle, also having a
crank to which is connected the forward end of a link, or rod, which is connected
at its inner end to the upper arm of a lever hung to a stud on the frame of the
secondary-pattern drum, the lower arm of the said lever having an inclined
head which is adapted to be acted upon by pins projecting from the end of the
said drum;. lience whenever the latter is moved so as to cause one of its studs.
to act upon a yarn guiding lever, a quick vibrating movement will be imparted
to the swinging blades, so that they will be first carried downward and then
permitted to again resume their normal or elevated position and, by reason of
this, all of the idle yarns will be drawn taut or caused to follow a straight line*
from the yarn guiding eye of each lever to the inner edge of the depressed
blade, so that the yarn of the lever which is depressed cannot carry down with it'
any other of the yarns as it might do if these yarns were simply floating loosely;
and, moreover, the yarn from the eye of the depressed lever is carried directly
across the path of the needles so as to insure the feeding of the yarn to the latter
at the proper place.
Secured to the frame which carries the secondary pattern drum is a plate
which has, at one end, a segmental needle guard, the latter being of inverted
U-shape so that the raised needles can pass between the inner and outer walls
of the same, the outer wall of the said needle guard, at the end which the
needles approach in their movement, being inclined, and this inclined edge being
bevelled so as to form a latch turner for throwing down into their proper position
any latches which may have accidentally been raised and which would, if not
thus depressed, interfere with the perfect, or proper, feeding of the yarn to the
needles having such raised latches.
Secured to the inner wall of the needle guard and extending part way around
the circular series of needles on the inner side of the same is a yarn deflector
preferably consisting simply of a bent plate, or wire, this deflector serving as a*

page_text: bearing for the idle yarns running from the yarn guiding eyes of the elevated
yarn levers so that the said idle yarns are directed in a course which will prevent
them from becoming engaged with the needles.
One side of the frame which carries the secondary pattern drum is provided
with a plate carrying a rod, or pin, which extends under the inner arms of the
thread guiding levers and serves as a stop for the downward movement of the
said inner arms of the levers under the action of springs, whereby the inner arms
of the said levers are normally drawn downward.
By this means contact of the inner ends of the levers with the surface of the
secondary pattern drum is prevented and the friction and wear which would
result from such contact are obviated.
The frame carrying the secondary pattern drum and also the thread guiding
levers and their appurtenances can be swung backwards on its trunnions so as
to carry the said thread guiding levers and their appurtenances away from the
upper portion of the needle cylinder in order to permit of the ready removal
of the said cylinder from the machine and the ready re-insertion of the same,
or the insertion of another cylinder in its place, this being necessary when the
machine is used for producing striped tubes for the legs of stockings, and another
machine is used for making the feet, as in such case it is preferable to transfer
the needle cylinder with the work upon it from one machine to the other rather
than to cast off the work from the needles of the cylinder as the latter course
necessitates not only the running on of the stitches of the knitted tube upon
the needles of the footing machine but it also necessitates the setting up of the
stitches upon the needles of the striping machine preparatory to the production
of a fresh web thereon.
When the frame which carries the secondary pattern drum is depressed or
occupies its normal position, that is to say, with the thread guiding levers and
their appurtenances in operative relation with the needles of the needle cylinder,
it is supported by the seating of the projecting ends of the drum shaft in pockets
in the opposite brackets, or standards, to which the frame is hung, and is locked
in this position by means of a pivoted bolt hung to the underside of one of the
side bars of the frame and engaging with a notch in one of the brackets on the
cam box of the machine, the lever being held in this locked position by the
action of a spring.
The locking lever is connected, by a link, to a swinging arm hung to the
drum shaft and having two notches and each adapted for the reception of a pin
projecting from one of the brackets, or standards, to which the drum carrying
frame is hung, one notch receiving the said pin when the frame is depressed
and the other notch receiving the pin when the said frame is raised, the arm
then serving to support the frame in the elevated position from which it cannot
be moved until the arm is withdrawn by the action of the locking lever.
The arm also aids in locking the frame in the depressed position since outward
swinging movement of the said arm to a certain extent is necessary before the
frame can be lifted.
The means whereby the movement of the secondary pattern drum is con-
trolled are as follows:-
At one end of the primary pattern drum is a screw thread and at the other
end of the drum are openings disposed in a spiral series the spiral having the
same pitch as the screw thread, and certain of these openings receive pins, or
plugs, which can be readily applied, or removed, so as to vary the disposition
of the plugs upon the drum. The plugs may simply have stems fitting snugly
in the openings, or the plugs may have threaded stems, and the openings may
be internally threaded for the reception of the same.
Free to slide on the rock shaft before referred to, but splined thereto, so as to
have no rotating movement independently thereof, is a sleeve which has, at
one end, a blade, or plate, engaging with the screw thread on the primary pattern
drum, the other end of the said sleeve having a bracket to which is pivoted a

page_text: pawl adapted to be acted upon by the plugs of the drum as the latter rotates,
the longitudinal movement of the sleeve, under the influence of the screw
thread, serving to maintain the pawl always in line with the spiral row of plugs.
The pawl is so mounted on the bracket that it opposes a rigid resistance to
the action of the plugs when the drum is travelling forward, but it can be
tripped on the backward movement of the drum, a spring permitting such trip
ping movement and restoring the pawl to its normal position after each such
movement.
The pawl has two faces for being acted upon by the plugs of the drum, the
one first acted upon by the plug being closer to the pivotal axis of the drum
than is the other, and these two faces being separated from each other by a
space which rests upon the plug after it has moved the pawl by contact with
the first acting face of the same, and before it imparts further movement to the
pawl by contact with the second acting face on its next forward movement.
By reason of this each of the plugs imparts two successive movements to the
pawl and hence to the bracket, sleeve and rock shaft, two successive movements
of the primary pattern drum being necessary to effect a complete forward swing-
ing movement of the rock shaft for a purpose hereafter made clear.
A screw stem is adapted to a threaded opening in the bracket so that it can
be longitudinally adjusted in respect to the said bracket and can be locked in
position after adjustment by means of a nut and the enlarged head of this screw
stem fits between lugs projecting upwardly from a cam plate which is mounted
so as to slide freely upon the projecting base flange of the annular cam box of
the machine, the said plate having a cam which acts upon the draw-down
lever hung to the said cam box, the said lever acting upon a pin which projects
from the draw-down cam of the said cam box and is adapted to an inclined
slot in the latter so that when the lower end of the lever is lifted by the action
of the cam plate, the draw down cam will be depressed in the cam box and will
draw down the needles of the cam cylinder to such an extent as to form long
stitches but when the cam plate is moved so as to free the draw down lever from
the influence of its cam the draw down cam will be permitted to rise in the
cam box and shorter stitches will be drawn by the needles of the needle cylinder
thereby providing for the production of stiff or slack work, as desired, the point
at which the character of the work changes being dependent upon the longi-
tudinal relation of the cam plate to the bracket and this relation being changed
as desired by the adjustment of the screw stem.
A lug or projection, on the cam plate, serves, by contact with a pin on the
knock-off lever, to automatically stop the operation of the machine when the
production of the desired length of knitted web has been effected.
In addition to the provision for slackening and stiffening the knitted web
furnished by the aforesaid cam plate the machine has mechanism whereby the
length of stitch can be increased for a few wales of the course in which the
change in knitting yarn is effected, and also by preference in the course preceding
and in the course following the said change course. The reason for this will
be understood when it is borne in mind that at the point where the change takes
place both yarns are fed to the needles and form stitches for a few wales, and
in the absence of any provision for slackening the wales at and near the point
where the change of arn is effected, this formation of double stitches would in
producing stiff work have a tendency to overload the needles and cause the
stitches to cut, or break, thus producing defective work.
The stitches are therefore lengthened slightly both in the change course and
n the courses preceding and following the same at, and near the point where
he change of yarn is effected this result being accomplished in the following
manner.
In a suitable radial slot in the table, or bed, of the machine is guided a bar
which may be termed a stitch bar, and which is acted upon by a coiled spring

page_text: tending to move it inwardly so that its inner end will project into the path of the
cam like periphery of the needle cylinder carrier which has a conformation
hereinafter described, the stitch bar being normally retained in the retracted.
position by engagement of a pin on the said bar with a finger projecting laterally
from the retainer arm en the rock shaft, which controls the operation of the
actuating pawl for the secondary pattern drum.
The stitch bar has at its outer end a slot for the reception of a guide pin
and the inner end of the bar can rise and fall as well as move inward and
outward under the influence of the cam on the periphery of a flange of the
cylinder carrier.
The stitch bar is adapted to act upon a pin depending from an arm which
projects from the draw down lever, hence whenever the said stitch bar is elevated
the draw down cam will be depressed and will be retained in the depressed
position so as to form long stitches, as long as the said stitch bar is thus held
up the draw down cam resuming its normal position so as to draw shorter
stitches as soon as the stitch bar is allowed to drop.
:
The flange of the needle cylinder carrier has a segmental peripheral portion
with its ends rounded or bevelled, so as to act with a lifting effect upon the inner
end of the stitch bar when the same has been projected into the path of the
said segment, and the said flange also has another segment with rounded; or
bevelled, ends which will push the stitch bar outward when it is subjected to
their action, these segmental cams being separated from each other by recesses
into which the inner end of the stitch bar can be projected by the action of
its spring when the said bar is released from the control of the finger on the
retainer arm.
Owing to the fact that the pawl, which is acted upon by the plugs of the
primary pattern drum, has two acting faces at different distances from the axis
of the drum, the action of a plug of the said drum upon the first face of the pawl
will not cause such movement of the retainer arm as to release the pin of the
secondary ratchet lever from the control of the bent end of the said arm, but
this movement is sufficient to raise the finger of the arm out of engagement
with the pin of the stitch bar and the inner end of the latter is therefore pro-
jected by its spring into a recess in the periphery of the cylinder carrier flange,
whereby it can be acted upon by the lift cam of the said flange so as to be
raised and thus operate the draw down lever and draw down cam. so as to draw
longer stitches upon a certain number of needles of the cylinder, this number
being represented by the peripheral extent of the said lift cam.
As soon as the lift cam passes from under the stitch bar the latter drops so
as to permit of the rise of the draw down cam and the resumption of the normal
length of stitch in the fabric, and the bar is then pushed outward by the push
cam of the cylinder carrier but immediately re-enters the recess of the same
owing to the fact that the retaining finger is still raised and does not retain the
stitch bar in the retracted position.
.
On the next forward movement of the plug of the primary pattern drum a
further movement is imparted to the pawl and to the rock shaft and retainer
arm, and the secondary ratchet lever is now released so that its pawl will engage
with the ratchet wheel of the secondary pattern drum and move the latter. to
the extent of one tooth. This brings about a re-arrangement of the yarn guide
levers and a change of the yarn and whilst this is being effected. the lift. cam
of the needle cylinder carrier is again acting upon the stitch bar: so as to depress
the draw-down cam and form longer stitches in the knitted web, the said lift
cam being so timed in respect to the cam. which effects the movement of the
secondary pattern drum, that such long stitches will always be drawn at the
time that the change in knitting yarn is being effected.
The stitch bar is again pushed. out by the push cam of the cylinder carrier,
but again moves inward, owing to the fact that the retaining finger is still raised,
hence there will be still another lifting movement of the stitch bar by the lift

page_text: cam and the formation of another series of longer stitches in the course following
that in which the change of yarn was effected, but meantime the primary pattern
drum has been moved forward again to the extent of one tooth and, if no other
change of yarn is to be effected, the pawl, which is under the control of the plugs
of the said drum, drops again so as to lower the retainer arm into position for
again retaining the secondary ratchet lever, and at the same time lowers the
retainer finger into position to engage with the pin of the stitch bar so as to
retain the latter when it is again pushed out by the push cam of the cylinder
carrier, the elasticity of the finger permitting it to yield upwardly as the pin
is pushed under the curved, or bevelled front portion of the same, and the finger
then springing down in front of the pin so as to retain the stitch bar in the
retracted position.

Improvements in Knitting Machines and Knitted Fabrics.
I, JAMES YATE JOHNSON, of 47, Lincoln's Inn Fields, in the County of London,
Gentleman, do hereby declare the nature of this invention (which has been
communicated to me from abroad by Robert Walter Scott and Louis Napoleon
Devon Williams, both of No. 2077, East Cumberland Street, in the City and
County of Philadelphia, State of Pennsylvania, United States of America,
Manufacturers of Knitting Machinery) and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
This invention relates to that class of knitting machines which are intended
for the production of striped fabrics by the use of continuous knitting yarns the
yarn or yarns not in use floating on the inner side of the tube from stripe to
stripe.
In such machines a series of yarn guides are employed one for each of the
yarns used and these guides are controlled by mechanism whereby the feed end
of either guide can be moved into or out of feeding relation to the needles so
that any desired yarn can be fed to the needles throughout as many courses as
may be desired.
The objects of the present invention are-
First To provide for the ready insertion or removal of the needle cylinder,
so that after a certain length of striped tube has been knitted, the needle
cylinder, with the knitted tube upon the needles, can be removed for application
to a separate machine which adds to the said tube a knitted web adapted to form
the foot of a stocking of which the striped tube constitutes the leg.
Second: To produce a closely knitted web or a slack stitch knitted web, as
desired.
Third To slacken the stitches of the web at and near the point where the
yarn changes, and thereby prevent straining, cutting, or tearing of the web
which might otherwise result from the presence of double yaru stitches, in
certain wales, wherever a change of yarn is made.
Fourth. To prevent engagement of the floating yarn or yarns by the needles,
and to insure the prompt engagement of the new yarn whenever a change takes
place; and

page_text: Fifth. To provide simple and efficient mechanism for automatically operating
the thread guides and other parts of the machine.
These objects we attain in the manner hereinafter set forth reference being
had to the accompanying drawings in which
Fig. 1, is a plan or top view of sufficient of the knitting machine to illustrate
our present improvements.
Fig. 2, is a transverse section on the line X-X Fig. 1.
Fig. 3 is a view partly in transverse section through the needle cylinder,
cam cylinder and bed plate and partly in end elevation looking in the direction
of the arrow y. Fig. 1 a number of parts in the distance being omitted in order
to avoid confusion.
Fig. 4, is a sectional plan view on the line W--W Fig. 3.
Figs. 5 to 18 inclusive are detached views of various parts of the machine
illustrating features of construction not shown with sufficient clearness in the
general views and
Fig. 19, is an enlarged or exaggerated view of part of a tubular web of fabric
such as our machine is designated to produce.
The fixed table or bed of the machine is represented at. 1, this table or bed
having suitable depending bearings for a driving shaft 2 which may be operated
either by hand or power as desired, the operation in the latter case being con-
trolled by a clutch which can be moved by means of a shipper lever 3 (shewn
in Figs. 1 and 2) so as to arrest the operation of the machine in the manner
hereinafter set forth.
The shaft 2 has secured to it a bevel wheel 4 which meshes with a bevel
pinion 5 secured to or forming part of the needle cylinder carrier 6, as shown in
Fig. 3, this carrier having an annular flange 7 which extends up into the needle
cylinder 8, is split at one or more points as shown by dotted lines in Fig. 3 and
is tapered internally for the action of an annular wedge 9 having a hollow
screw threaded stem 10 extending down below the carrier 6 and engaging with
a nut 11 which bears upon the underside of the said carrier and has at its lower
end an annular flange 12 whereby it may be readily manipulated. By turning
this nut in one direction the wedge 9 is drawn down and thereby caused to
expand the split and tapered flange 7 in order to firmly clutch the needle
cylinder 8 to the carrier 6, or the nut may be turned in the reverse direction
so as to permit the wedge to rise and thus allow the ring 7 to contract until
its hold upon the needle cylinder 8 is released and the cylinder, with its needles
can be removed from the carrier and from the annular cam cylinder 13 which
surrounds the lower portion of the needle cylinder and is secured in any con-
venient manner to the table or bed 1.
Mounted upon the upper portion of the needle cylinder is a web holder ring 14
carrying a series of radially guided web holders 15, which as the needle cylinder
rotates, are moved back and forth by a cam 16" and are at other times held
in the projected position by a cam 16 (Fig. 17) upon a web holder cam ring 16
which surmounts and surrounds the ring 14, the said web holder cam ring
being prevented from rotating with the needle cylinder by reason of one or other
of a pair of lugs 17 on the ring engaging with a fixed arm or bracket 19 pro-
jecting upwardly from the annular cam cylinder 13 as shown in Fig. 3, a certain
amount of play being permitted between the lugs 17 in order that the web holder
operating cams will assume their proper relation to the knitting cams whether
the needle cylinder is being rotated to the right or to the left.
Each of the web holders 15 has at the bottom a shoulder 15* as shewn in
Fig. 18, which shoulder by contact with the upper portion of the needle cylinder 8.
will prevent undue inward movement of the web holders when they are passing
the points of junction of the cams 16 and 16b, undue outward movement of the
web holders at such points being prevented by contact of the outer ends of
said web holders with the rim of the web holder ring 14.
On the shaft 2 is a grooved cam 20 which engages with a pin 21 projecting

page_text: from the lower end of a lever 22, the latter being hung so as to be free to swing
upon a shaft 23 mounted in suitable bearings in the table or bed 1 and in a
longitudinally projecting arm or bracket 24 on said table or bed.
<
The lever 22 carries a pivotted pawl 25, as shewn in Fig. 5, and by dotted
lines in Fig. 2 the said pawl being acted upon by a spring 26 whereby it is
held in engagement with the teeth of a ratchet wheel 27 secured to one end
of a drum 29, which we will hereafter designate as a primary pattern drum,"
and which is mounted so as to be free to turn upon a shaft or spindle 30 secured
to and projecting from the table or bed 1, a handle 31 at the outer end of the
hub 32 of the drum serving as a means whereby the latter may be rotated
independently of the pawl and ratchet mechanism when desired.
Backward motion of the drum 29 is normally prevented by means of a retainer
pawl or detent 33 carried by a lever 34 which is hung to a pin 35 carried by
a bracket 36, the. latter being secured to and projecting upwardly from the
longitudinal arm 24 on the fixed table or bed of the machine. By depressing
the outer end of the lever 34, however, the retaining pawl or detent 33 can
be withdrawn from engagement with the teeth of the ratchet wheel 27 and at
the same time and by the same action the pawl 25 will also be withdrawn from
engagement with said teeth, owing to the fact that a set screw 37 on the lever 34
strikes a projecting tail 39 on the pawl 25 and thereby effects the retraction of
the latter.
The outer end of the lever 34 may be held in the depressed position for any
desired length of time by swinging into engagement therewith a pivoted arm
or catch 40 hung to the bracket 30 as shown in Figs. 1 and 2.
Secured to the shaft 2 is a cam 41 which acts upon an enlargement or shoe 42
at the lower end of a lever 43 which is loosely hung upon the shaft or spindle 30.
and carries at its upper end a pawl 44 adapted to engage with a ratchet wheel 45
secured to the shaft 46 of a drum 47 hereinafter designated a secondary pattern
drum" and which is carried by a yoke or frame 49 having trunnions 50 mounted.
in brackets 51 on the fixed table or bed, as shewn in Figs. 1, 2 and 3.
66
The pawl 44 is acted upon by a spring 52 which tends to pull the toothed
end of the pawl into engagement- with the teeth of the ratchet wheel 45, this
movement being restricted by contact of the projecting finger 53 of the pawl.
with a pin or stud 54 projecting from one of the brackets 51.
The upper end of the lever 43 is drawn rearwardly by the action of a spring 55.
but this movement is normally restricted by contact of a pin 56 on the lever
with the bent end 57 of an arm 59, the latter being secured to the inner end.
of the shaft 23, hence, so long as the movement of the pawl 44 is thus restricted
it will not move the ratchet wheel 45, this movement being less than the length
of a tooth of said wheel. When, however, the bent end of the arm 59 is raised
so as to free the pin 56 from its control, the upper arm of the lever 43 and its
pawl 44 will be drawn forward under the action of the spring 55 so that the pawl
will engage a fresh tooth of the ratchet wheel 45, and when the lever 43 is
actuated by the cam 41, will move said ratchet wheel and also the secondary
pattern drum 47 to the extent of one tooth.
A projecting stud 58 serves to limit the downward movement of the bent
end 57 of the arm 59 under the influence of the spring 58, Fig. 6, and thus
limits the rocking movement of the shaft 23 towards the primary pattern drum 29.
The secondary pattern drum 47 carries projecting lugs or pins 60 which act.
upon thread guiding levers 61 hung to a suitable transverse pin on the frame 49,
the outer ends of these levers 61 having eyes for the guidance of the knitting
yarns and the levers being so disposed in respect to the needles of the machine
that when the outer end of the lever is depressed its yarn guiding eye will be
in position to feed the yarn to the needles of the cylinder, but when said outer
end of the lever is raised its yarn will be fed over the tops of the needles and
will not engage the same, hence by a proper manipulation of the levers 61,
due to a proper disposal of the pins or studs 60 upon the drum 47 any desired

page_text: one of the levers may be caused to feed its yarn to the needles, the other yarns
floating on the inside of the web ready to be likewise brought into action when
required, so that the striping of the web by the feeding of different colored
yarns successively to the needles and the change from one color to another can
be instantly effected without any stoppage of the rotation of the needle cylinder.
An arm 62 projects forwardly from one side of the frame 49 and carries at
its outer end a spindle 63 to which is secured a hub 64 having a series of pro-
jecting blades 65 which fit between the forward ends of the yarn guiding
levers 61, as shown in Fig. 1, the shaft or spindle 63 also having a crank 66
to which is connected the forward end of a link or rod 67 which is connected
at its inner end to the upper arm of a lever 68 hung to a stud on the frame 49
and acted upon by a spring 69, the lower arm of said lever having an inclined
head 70 which is adapted to be acted upon by pins 71 projecting from the end
of the drum 47, hence, whenever said drum is moved so as to cause one of its
pins or studs 60 to act upon a yarn guiding lever, the lever 49 will also be
actuated and a quick vibrating movement will be imparted to the blades 65,
whereby said blades will be first carried downward to the position shown
by dotted lines in Fig. 3 and then again permitted to resume their normal or
elevated position under the action of the spring 69, and by reason of this, all
of the idle yarns will be drawn taut or caused to follow a straight line from the
yarn guiding eyes of the levers to the inner edges of the depressed blades, hence
the yarn of the lever which is being depressed cannot carry down with it any
other of the yarns as it might do if these yarns were simply floating loosely,
and the yarn from the eye of the lever, when the latter is fully depressed, will
be carried directly across the path of the needles so as to insure the feeding of
the yarn to the latter at the proper place.
Secured to the frame 49 is a plate 72 which has at one end a segmental needle
guard 73 the latter being of inverted U shape so that the raised needles can
pass between the inner and outer walls of the same, the outer wall of the said
needle guard, at the end which the needles approach in their movement, being
inclined, as shewn in Fig. 2, and this inclined edge 74 being bevelled, as shown
in Figs. 2 and 7, so as to form a latch turner for throwing down into their
proper position any needle latches which may have accidentally been raised and
which would, unless thus depressed, interfere with the perfect or proper feeding
of the yarn to their needles.
Secured to the inner wall of the needle guard 73 and extending partway
around the circular series of needles, on the inner side of the same, is a yarn
deflector 75 preferably consisting simply of a bent wire or plate, this deflector
serving as a bearing for the idle yarns running from the yarn guiding eyes
of the elevated levers 61 so that said idle yarns are directed in a course which
will prevent them from becoming engaged with the needles.
One side of the frame 49 is provided with a plate 76 as shown in Figs. 1,
3 and 8, this plate carrying a rod or pin 77 which extends under the rear arms
of the thread guiding levers 61 and serves as a stop for the downward movement
of said rear arms of the levers under the action of the springs 78 whereby
they are normally drawn downward.
By this means contact of the rear ends of the levers 61 with the surface of the
drum 47 is prevented and the friction and wear which would result from such
contact are obviated.
The frame 49, with its thread guiding levers and their appurtenances can be
swung backward on the trunnions 50 so as to carry said thread guiding levers
and their appurtenances away from the upper portion of the needle cylinder in
order to permit of the ready removal of said cylinder from the machine and the
ready re-insertion of the same or the insertion of another cylinder in its place,
this being necessary when the machine is used for producing striped tubes for
the legs of stockings and another machine is used for making the feet as in such
case it is preferable to transfer the needle cylinder with the work upon it, from

page_text: one machine to the other, rather than to cast off the work from the needles of
the cylinder as the latter course necessitates the running on of the stitches of
the knitted tube upon the needles of the footing machine.
When the arm 49 is depressed or occupies its normal position, that is to say
with the thread guiding levers and their appurtenances in operative relation with
the needles of the needle cylinder, said arm is supported by the seating of the
projecting ends of the drum shaft 46 in pockets in the opposite brackets or
standards 51 and is locked in this position by means of a pivoted bolt 90 hung
to the underside of one of the side bars of the frame and engaging with a notch
in the bracket 19 as shown in Fig. 3 the lever being held in this locked position
by the action of a spring 91.
The lever 90 is connected by a link 92 to a swinging arm 93 hung to the
drum shaft 46 and having two notches 94 and 95 each adapted for the reception
of a pin 96 projecting from one of the brackets or standards 51 the notch 94
receiving said pin when the frame 49 is depressed and the notch 95 receiving
the pin when said frame is raised as shown in Fig. 9 the arm 93 then serving
to support the frame 49 in the elevated position from which it cannot be moved
until said arm is withdrawn by the action of the lever 91 so as to free the notch 95
from engagement with the pin 96.
The arm 93 also aids in locking the frame 49 in the depressed position since
swinging movement of said arm 93 to a certain extent is necessary before the
frame 49 can be lifted. The movement of the secondary pattern drum 47 is con-
trolled as follows.
At one end of the primary drum 29 is a screw thread 100 and at the other end
of the drum is a series of openings 101 disposed in spiral form said spiral having
the same pitch as the screw thread 100 and certain of these openings 101 receive
pins or plugs 102 which can be readily applied or removed so as to vary the
disposition of the pins upon the drum thus the pins may simply have stems
fitting snugly in the openings 101 or said pins may have threaded stems and
the openings may be interally threaded for the reception of the same.
Free to slide on the shaft 23 but splined thereto so as to have no, rotating
movement independently thereof is a sleeve 103 which has at one end a blade
or plate 104 engaging with the screw thread 100 on the drum 29 the other end
of said sleeve having a bracket 105 to which is pivoted a pawl 106, adapted
to be acted upon by the pins 102 of the drum 29 as the latter rotates the longi-
tudinal movement of the sleeve 103 under the influence of the screw thread 100
serving to maintain the pawl 106 always in line with the spiral row of pins 102.
The pawl 106 is mounted on the bracket 105 as shown in Fig. 10 so that it
opposes a rigid resistance to the action of the pins 102 when the drum 29 is
travelling forward or in the direction of the arrow Fig. 2 but it can be tripped
on the backward movement of the drum, a spring 107 permitting such tripping
movement and restoring the pawl to its normal position after each such
movement.
The pawl 106 has two faces 109 and 110 for being acted upon by the pins 102
of the drum 29 the face 109 being the one first acted upon by the pin as shown
in Fig. 11 and being further from the axis of the drum 29 than the face 110
these two faces being separated from each other by a space 111 upon which the
pin 102 bears as shown in Fig. 12, after it has moved the pawl by contact with
the face 109 and before it imparts further movement to the pawl by, contact
with the face 110 on its next forward movement as shown in Fig. 13. By
reason of this construction each of the pins 102 imparts two successive,movements
to the pawl 106 and hence to the bracket 105 sleeve 103 and shaft 23 three
successive movements of the primary pattern drum 29 being necessary in order
to, effect a complete back and forth rocking of the shaft 23 for a purpose rendered
apparent hereafter.
A screw stem 112 is adapted to a threaded opening in the bracket 105 so that

page_text: it can be longitudinally adjusted in respect to said bracket and can be locked
in position after adjustment by means of a nut 113 and the enlarged head 114
of this screw stem fits between lugs 115 projecting upwardly from a cam plate 116
shown in Fig. 14 said can plate being mounted so as to slide freely upon the
projecting base flange of the annular cam cylinder 13 and having a cam
surface 117 which as shown in Figs. 3 and 15 acts upon a set screw 118", carried
by a lever 118 which is hung to said cam cylinder said lever acting upon a
pin 119 which projects from the draw down cam 120 of the cam cylinder and
is adapted to an inclined slot 121 in the latter, as shown in Fig. 15 sc that when
the lower end of the lever 118 is lifted by the action of the cam 117 the draw
down cam 120 will be depressed in the cam cylinder and will draw down the
needles of the needle cylinder to such an extent as to form long stitches but
when the bar 116 is moved so as to free the set screw 118" of the lever 118
from the influence of the cam 117 the draw down cam 120 will be permitted
to rise in the cam cylinder and shorter stitches will be drawn by the needles
of the needle cylinder thereby providing for the production of slack or stiff work
as desired the point at which the character of the work changes being dependent
upon the longitudinal relation of the cam 117 to the bracket 105 and this
relation being changed as desired by the adjustment of the screw stem 112.
A lug or projection 122 on the cam bar 116 serves by contact with a pin 123
on the knock off lever 3 to automatically stop the operation of the machine
when the production of the desired length of knitted web has been effected.
In addition to the provision for slackening and stiffening the knitted web
furnished by the cam 116 we provide the machine with mechanism whereby
the length of the stitch can be increased for a few wales of the course in which
the change in knitting yarn is effected and also by preference in the course
preceding and in the course following said change course. The reason for this
will be understood on reference to Fig. 19 which represents an exaggerated
view of a piece of the knitted web at and near the point where the yarn changes.
On reference to this figure it will be observed that at the point where the change
takes place both yarns are fed to the needles and form stitches for a few wales,
and in the absence of any provision for slackening the wales at and near this
point such formation of double stitches would in producing stiff work, have a
tendency to overload the needles and cause the stitches to cut or break. We
therefore lengthen the stitches slightly both in the change course and in the
courses preceding and following the same in that portion of the web where a
change of yarn is effected, as will be fully understood on reference to Fig. 19
this result being accomplished in the following manner.
In a suitable radial slot in the table or bed of the machine is guided a bar 124
which may be termed a "stitch controlling bar" and which is acted upon by a
coiled spring 125 tending to move it forwardly so that its forward end will
project into the path of the cam like periphery of the needle cylinder carrier 6,
which has the configuration shewn in Figs. 4 and 16, and hereafter to be described.
the bar 124 being normally retained in the retracted position as shown in Figs. 3
and 4 by engagement of a pin 126 on said bar with a finger 127 which projects
laterally from the arm 59 of the shaft 23, whereby the operation of the pattern
drum actuating pawl 44 is controlled. The bar 124 has at its rear end a
slot 129 for the reception of a guide pin 130 and the forward end of bar 124
can rise and fall as well as move forward and backward under the influence of
the cams on the periphery of the needle cylinder carrier 6.
The bar 124 is adapted to act upon a pin 131 depending from an arm 132
which projects from the lever 118 whereby the draw down cam 120 will be
depressed and will be retained in the depressed position as long as said bar 124
is held up, said draw down cam resuming its normal position as soon as the
bar 124 is allowed to drop.
The flange of the needle cylinder carrier 6 has a segmental peripheral por-
tion 133 with its ends rounded or bevelled as shewn in Fig. 16, so as to act with

page_text: a lifting effect upon the forward end of the bar 124 when the same has been pro-
jected into the path of said segment, and the said flange also has another
segment 134 with rounded or bevelled ends such as shown in Fig. 4, which
will push the bar 124 outward when it is subjected to their action, these
segmental cams 133 and 134 being separated from each other by recesses 135
and 136 into which the forward end of the bar 124 can be projected by the action
of the spring 125 when said bar is released from the control of the finger 127.
Owing to the fact that the pawl 106 has two acting faces 109, 110, at different
distances from the axis of the primary pattern drum 29, the action of a pin. 102
of said pattern drum upon the face 109 of the pawl will not cause such move-
ment of the arm 59 as to release the pin 56 of the lever 43 from the control of
the bent end of said arm, but this movement is sufficient to raise the finger 127
out of engagement with the pin 126 of the bar 124, hence the forward end of
the latter is projected by the spring 125 into the recess 135 in the periphery
of the cylinder carrier flange whereby it can be acted upon by the cam 133 so
as to be lifted and thus operate the lever 118 and draw down cam 120 so as to
draw long stitches upon a certain number of needles of the cylinder, this number
being that represented by the peripheral extent of the cam 133.
As soon as the cam passes from under the bar 124 the latter drops into the
recess 136 so as to permit of the rise of the draw down cam and the resumption
of the normal length of stitch in the fabric, the bar 124 being then pushed
backward by the cam 134 but immediately entering the recess 1335 again owing
to the fact that the finger 127 is raised and does not retain the bar 124 in the
retracted position.
On the next forward movement of the plug 102 of the primary pattern drum 29
a further movement is imparted to the pawl 106, shaft 23 and arm 59, and the
lever 43 is now released so that its pawl 44 will engage with the ratchet wheel 45
and move the same and the secondary pattern drum 47 to the extent of one
tooth. This brings about a rearrangement of the yarn guide levers and a change
of the yarn and at the same time that this is being effected the cam 133 is again
acting upon the bar 124 so as to depress the draw-down cam 120 and form longer
stitches in the knitted web, the cani 133 being so timed in respect to the cam 4.1
which effects the movement of the secondary pattern drum 47 that such long
stitches will always be drawn at the time that the change in knitting yarn is
being effected.
The bar 124 again drops into the recess 136, is again pushed back by the
cam 134, and again moves forward, owing to the fact that the finger 127 of
the arm 59 is still raised, hence there will be still another lifting movement
of the bar 124 by the cam 133 and the formation of another series of longer
stitches in the course following that in which the change of yarn was effected,
but meantime the primary pattern drum 29 has been moved forward again
to the extent of one tooth and if no other change of yarn is to be effected the
pawl 106 drops to the position shown in Figs. 2 and 11, so as to permit the
arm 59 to descend into position for again retaining the lever 43 and at the same
time bring the finger 127 into position to engage with the pin 126 so as to
retain the latter when it is again pushed back by the cam 134, the inherent
elasticity of the finger 127 permitting it to yield upwardly as the pin is pushed
under the curved or bevelled front portion of the same and the finger then
springing down in front of the pin so as to retain the bar 124 in the retracted
position.
In some cases it may not be necessary to lengthen the stitches in the course
following the change course, as the strain is exerted mainly upon the double,
yarn stitches in the change course and the corresponding stitches in the pre-
ceding course, and it might even be possible to knit loosely only the stitches
in the course preceding the change course, in which case the double yarn, stitches
would draw through the long stitches of said preceding course, so as to prevent
the breaking of the yarn. In order to effect these changes in the knitted, web
.

page_text: it is simply necessary to operate the retainer 127 so as to release the stitch bar 124
for one, two or three courses, as desired.
