Improvements in Knitting Machines.
I, JOHN FRANKLIN NELSON, of Rockford, in the County of Winnebago and
State of Illinois, U.S.A., Manufacturer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The primary object of my invention is to knit a finished sock with a ribbed top by
one continuous operation of automatic mechanism. Heretofore, so far as I am aware,
this has never been accomplished. Usually, where the main portion of the sock is
knit on a straight machine, the ribbed top is knit on a separate machine and stitched
to the sock proper by a third machine. In most circular machines for knitting this
class of goods the ribbed top is knit on one machine and then transferred to another
machine, which continues the knitting to complete the sock, with the exception of the
closing of the toe, which is done by a separate machine, or by hand. It has also been
proposed to knit the ribbed top and the other part of the sock on a circular machine,
but this machine was not adapted to close the toe and was not automatio like mine.
Never, so far as I am aware, has a straight knitting machine been devised in which
any attempt was made to knit the ribbed top and the other portion of the sock by a
continuous operation of the mechanism in a single machine.
I have embodied my improvemements in a parallel row or straight knitting
machine which not only knits the entire sock, including the ribbed top, by one
continuous operation of automatic mechanism, but also closes the toe, thus producing
a sock complete in every respect. Thus a large number of machines can, under
the supervision of a single attendant, be made to each automatically knit, without
assistance, an indefinite number of completed socks.
While I have stated the primary object of my invention to be the knitting of a
finished sock by one continuous operation of automatic mechanism, I wish it under-
stood that this is not the sole object of my invention, nor does my invention reside
wholly in a machine entirely automatic; on the other hand it includes many
nechanisms and groups of mechanisms which are novel. useful and efficient. The
scope of my invention as I now understand it is set forth in as broad terms as I can
now command, as well as in detail, in the claims at the end of this specification.
In currying out my invention in the way now best known to me, I employ two
parallel rows of needles operated by cams mounted on reciprocating slides and
controlled by a pattern cylinder to knit first the toe, then the foot, next the heel and
next the leg of the sock. Two additional sets of needles, called ribbing needles,
arranged. in rows parallel with those first mentioned are employed to co-operate with
some of the first mentioned needles to form the ribbed top. The ribbing needles are
held out of operation while the plain portion of the sock is being formed, but auto-
matically come into action at the proper time. They are in turn' automatically
thrown out of operation when the rib is completed and the knitting of a new sock is
begun.
The type of machine to which my improvements are shown applied is exemplified
in the Specification of Patent No. 1529. of 1879:

page_text: Fig. 27 shows particularly the manner in which a ribhing needle takes a loop from
a pair of transferring points.
Fig. 28 is a view on an enlarged scale and in horizontal section taken just below
the main portion of the ribbing needles, approximately on the line 28-28,
of Fig. 5.
Fig. 29 is a view similar to Fig. 28 with the parts in a different position. In
Fig. 28 the cams, etc., are in the position which they occupy in making the foot or
the leg of a sock, while in Fig. 29 the same parts are shown in the position which
they occupy when knitting the rib.
Fig. 30 is a detail view, partly in plan and partly in section, illustrating the
positions of the cams on the back slide, and the switches and grooved bars which
control them when knitting the "set up" and the toe, or the heel of the sock.
Fig. 31 is a similar view of the cams, etc., of the front slide when knitting the toe
or the heel.
Fig. 32 is a view similar to Fig. 30 showing the same parts in the position they
occupy when the machine is knitting the foot or the leg of the sock.
Fig. 33 shows the positions of the cams, etc., of the front slide when knitting the
foot or the leg or the "set up."
Figs. 34 and 35 are similar views showing the positious of the cams, &c., of the
back and front slides, respectively, when knitting the rib.
Figs. 36 and 37 are detail views, in perspective, showing particularly the arrange-
ment of the switches and their operating mechanism at the left hand end on the
front side of the machine.
Fig. 38 is a similar view of the switch and its operating mechanism at the left-
hand end of the back side of the machine.
Fig. 39 is a similar view showing the switch and its operating meobanism at the
right-hand end of the back side of the machine.
Figs. 40 to 47, inclusive, illustrate the operation of the ribbing needles and the
transferring points for transferring the loops from the main knitting needles to
the ribbing needles.
Fig. 40 shows the arrangement of the parts before the ribbing needles are operated
and when the transferring points on the front side of the machine are only partially
advanced.
Fig. 41 shows the front transferring points advanced to the end of their upward
stroke, the back transferring points being partially advanced.
Fig. 42 shows the frout transferring points advanced to the limit of their upward
stroke and the back transferring points half way advanced, the back row of ribbing
needles having been moved through the transferring points of the front row.
In Fig. 43 the back transferring points have been advanced to the end of their
upward stroke, the front transferring points have been drawn half way down.
In Fig. 44 the back transferring points have been moved to the end of their
upward stroke, the front transferring points have been moved half way down, and the
front ribbing needles have been moved through the back transferring points to take
loops therefrom.
In Fig. 45 the front transferring points have been drawn all the way down, thus
leaving the loops on the back ribbing needles, the back transferring points having
been drawn partially down.
Fig. 46 shows particularly the manner of feeding the yarn on the back side of the
machine to the main knitting needles of the back side and the ribbing needles of
the front side. It will be observed that the yarn guide operates behind the ribbing
needles of the back side when laying yarn in the ribbing needles of the front side.
Fig. 47 indicates the manner in which the yarn guide on the front side of the
machine lays yarn in the ribbing needles of the hack side and the main 'knitting
needles of the front side.
Fig. 48 indicates the three kinds of yarn used in the fabric.
:
Figs. 49 to 55, inclusive, are diagrams illustrating the manner in which fabrie

page_text: is formed, and particularly the manner in which the ribbed fabric is joined to the
plain fabric, and the ribbed fabric is formed into a tube by the end needles.
Fig. 49 shows the two yarn guides advancing towards the end needle at the
right-hand end of the machine.
Fig. 50 shows the yarn guides advanced from the position shown in Fig. 49, the
back yarn having been grasped by the end needle.
Fig. 51 shows the two yarn guides still further advanced to the right, the end
needle having been further advanced, and the back yarn having been caught by the
open latch thereof.
In Fig. 52 the yarn guides are still further advanced to the right, the end
needle has been advanced, and grasped the front yarn, the latch being closed.
In Fig. 53 the end needle has been retracted and then advanced forming a
loop with the front yarn and interlocking it with a loop of the back yarn.
Fig. 54 illustrates particularly the manner in which the back yarn is carried
from the front side of the fabric and joined on again to the fabric on the back side.
Fig. 55 shows the manner in which the ribbed work joins the body and the
manner in which the ribbing on the back side of the fabric joins that on the front
side thereof.
The driving shaft, A, extending transversely across the machine is mounted in
suitable bearings in the main frame, A¹, which may be of any suitable construction.
A hand wheel, A2, is secured to the front end of the driving shaft, and at its rear end
the driving shaft is provided with fast and loose pulleys, as usual. A pinion, a, on
the driving shaft meshes with a main actuating gear wheel, a³, secured to a sleeve
mounted on a stud shaft, a², secured to a bracket, Z. The gear wheel, a¹, is connected
with a cam wheel or irregular snail gear B₁ which gears with a star pinion, B, for
operating the pattern cylinder, G, as will be hereinafter explained.
A front needle bed, C, and a rear needle bed, 0, are each slotted and provided with
a slotted plate, c, which constitute guides for the front and back rows of main
knitting needles, b and b¹, as well as for their jacks, B², B. The two beds are inclined,
as heretofore, and each is provided with a lower longitudinal grooved guide bar or
channel plate, C, and an upper longitudinal grooved guide bar or channel plate, C³.
A front main cam slide, C, and a back main cam slide, C5, rigidly connected by a
yoke, o¹, reciprocate longitudinally in the guide grooves in the front and back guide
bars. These main cam slides carry cams for actuating the two rows of main knitting
needles and are reciprocated by the mechanism next to be described.
An elbow lever, c, pivotally mounted on the main frame bracket, c³, by a stud, c^,
is connected at the upper end of its longer arm with a bracket, cs, on the back main
cam slide, C, by means of a pitman or link, c. The other end or shorter arm of the
elhow lever is linked by a connecting rod, 63, with a wrist pin, 64, on the gear' wheel,
a. The result of this organization is that the main cam slides are cansed to
reciprocate together or make two strokes for each revolution of the actuating gear, a³,
and to operate the two rows of main knitting needles by their cams, in the manner
hereinafter described.
The main yarn carrier, D, is actuated by a pitman, D₁, which is pivotally connected
with the upper end of a lever, G+, jointed at g to the elbow lever, 0%, and provided at
its lower end with a roller carrying stud, gl, engaging the forked end of a lever, g³,
pivoted at g³ to the main frame bracket, c, and at its upper end carrying a roller, g*,
which enters a groove in the actuating gear, a¹. The groove is suitably shaped to
give the proper movement to the yarn carrier and to the cams for operating the presser
hooks, allowing of the usual proper amount of dwell at each stroke and at the proper
times.
The front presser hooks, E, and the back presser hooks, E¹, are for the most part
constructed, mounted and operated in the same manner as heretofore. One of the
presser hooks at one end of the front row and one at the opposite end of the back row
are, however, operated in a somewhat different way, as will be hereinafter explained.
The front can carrying slide, E2, for the front row of presser hooks, is connected with
the yoke, cl, by an arm, E. As shown in Fig. 11 the arm, E³, operates in a recess, e,

page_text: in the cam slide so that the yoke and the main cam slides, C4, C5, may have a move-
ment at the end of each stroke, independent of the presser hook cam carrying slides,
in order that the presser books may be operated at the proper time relatively to the
movement of the needles, as in the prior Nelson machines. The cam, E, carried by
the slide, E, is arranged opposite a recess, e¹, and the construction and operation are
such that the presser hooks are elevated and depressed at proper times to hold down
the loops of the fabric during the operation of the needles. A recess, e³, is formed in
the slide, E², to permit the end presser hook to operate in the manner hereinafter
described.
The back cam carrying slide, F, is provided with a cam, FI, arranged opposite a
recess, f. The slide, F, is connected with the back cam slide, C³, by an arm, f¹,
secured to the slide, C, and operating between stops, f,, on the slide. The front
of the arm, f, slides through a recess, f, in a lug, F, secured to the slide, F. This
lug, F2, engages with a downwardly projecting arm, d, of the pitman, D', which
operates the main yarn carrier, D. The slide, F, is provided with a recess, f, just
below the lug, F2, to accommodate the presser hook ou the end needle, as hereinafter
described. The slides, E and F, and their cams operate upon the presser hooks in
substantially the same way as heretofore, the only practical difference being that the
slides are provided with recesses, e2 and 15, to allow the presser hooks on the end
needles to operate twice during each stroke. When the slides are moving to the
right, the arm, E³, inoves the slide, E³, by abutting against the shoulder at the right
hand end of the recess, e, and when moving to the left the arm, E³, abuts against the
shoulder of the left-hand end of this recess. When kuitting the body of the sock
and the back slide, C; is moving to the left, the arm, d, abuts against the stop, f³,
to move the slide, F. When the slide, C, is moving to the right, the arm, d, abuts
against the lug, F, and moves the slide, F, to the left until the pitman, D¹, stops.
These movements continue during the entire operation of the machine while forming
a sock.
When knitting the rib the pitman, D¹, is raised by the lever, D",,so that in 'the
movement of the slide, C³, to the left the arm, d, of the pitman, D¹, is raised above the
plane of the stop, , and does not move the slide, F, but the arm, A, causes
the slide, F, to move by striking against the portion,*, of the stop. When the
slide, C5, moves to the right the arm, d, strikes against the lug, F2, and when the
pitman, D¹, stops at the right the slide, I, is moved still further by the arm, f, which
engages with the stop,
The presser hook at the right hand end of the front row and that at the left hand
end of the back row are arranged to operate differently from the others. Each
of these presser hooks is provided with a spring, u10, as indicated in Fig: 29,. the
arrangement being such that the spring will cause the presser hook to rise when it is
free to move. It will be observed, by reference to Fig. 29, that when the slide, E²,
moves to the right, for instance, the presser hook at the right-hand end of the row will
be first caused to rise by means of the spring, a, the shank of the hook being
thrown back into the recess e. As the slide further advances the inclined portion
on the left-hand side of these recesses will move the shank of the presser hook
upwardly and backwardly, thus causing its front or hooked end to be depressed.
As the slide, ³, continues to move, the recess, e, will come in line with the end
presser hook, the spring, a, will force the shank of the hook into the recess, as
will also the cam, E. As the slide, E², continues to move the inclined portion at
the left-hand end of the recess, e¹, will move the shank of the presser hook back-
ward and depress its hooked end. It is thought that this operation will be clearly
understood without further explanation. The presser hook at the left-hand end of
the back row operates in substantially the same way and need not be explained.
The presser hooks, E, E¹, are mounted to oscillate in bars, D³, on opposite sides of
the central longitudinal opening of the machine. The cam slides, E, F, are recipro-
cated in guides between the bars, D² and (³.
The pattern cylinder, G, is mounted in suitable bearings, g³, in the main frame,
and revolves in the direction indicated by the arrow. It is actuated by means of a
"

page_text: used
pinion, h, on a shaft, h, with which the star wheel, B, is connected. This pinion is
provided with a single laterally projecting tooth, h2, in line with one of the teeth of
the pinion, h, and adapted to gear with the toothed segments, I, I, mounted on the
pattern cylinder. The pinion itself gears with a circular row of teeth, h³, formed on
the right-hand edge of the periphery of the cylinder. As in the prior Nelson
machines the pinion, h, turns the cylinder by its engagement with the teeth, h³, when
the toe and heel of the sock are being formed and also during a portion of the time
when the foot, leg and ribbed top are being made. During the main part of the
time when the foot or that part of the sock between the toe and the heel and the leg,
or that part of the sock above the heel, are being formed, and while the ribbed top is
being formed, the pinion will occupy one of the spaces, 1, 2, 3, while the tooth, h²,
will engage one of the segments, I, or I¹. These segments are constructed and operated
in much the same manner as in the prior Nelson machines. The segment, I,
in my improved machine during the formation of the leg and the ribbed top, while
the segment, I, is used during the formation of the foot. Each of the segments is
formed with a flange, i, that fits loosely in a groove, i, in the cylinder (as shown in
Fig. 8), and is guided therein to allow of a proper amount of movement of the
segments about the periphery of the cylinder. The cylinder is provided with four
series of holes, i³, 1, 4, 5, to receive pins, 6, 7 and, which extend across the
groove, ¹, between the ends of the segments. In the present machine the holes, i',
are not used. Soon after the toe of the sock has been completed, the pinion works in
the space, 1, and the tooth, h², on the pinion engages with the segment, I¹, and moves
it forward until its front end strikes the pin, . During the time when the segment
is thus being moved, the knitting is progressing without any movement of the
pattern cylinder, and as the tooth, h², engages with the segment only once in every
revolution of the pinion, a sufficient time is given to knit the foot before the pattern
cylinder begins to move. As soon, however, as the end of the segment, 1', strikes
the pin, 7, it will press against this pin and a further movement of the segment, will
cause the pattern cylinder to move. The pinion will then soon engage the teeth, ³,
of the cylinder which will be moved forward and the pinion will continue to actuate
the cylinder during the changing of the switches and during the formation of the
heel. After the completion of the heel, and after the switches are changed and a
portion of the foot is knit, the pinion, h, enters the space, 2, the cylinder stops
moving and the knitting of the leg is continued, the tooth, h, operating on the
segment, I, until it is moved forward against a spring dog, I, carried by the cylinder.
Then the cylinder is moved forward and the pinion, h, engages the teeth, h³, between
the spaces 2 and 3, and the cylinder continues to revolve during the transferring
operation, hereinafter described, when passing to the ribbed top. After the trans-
ferring is completed the pinion, h, enters the space, 3, where it remains during the
formation of the rib. The segment, I, is moved forward during the formation of the
rib without moving the cylinder until it strikes the pin, i, when the cylinder is again
moved forward and soon after this the toe of a new sock is begun. During the move-
ment of the cylinder while the transferring operation was going on, the spring dog,
I', was engaged by a stop, I', on the casing of the machine, and forced inward, so that
the flange, i, of the segment, I, was permitted to pass through the recess, 1³, in the
stop.
In order to prevent the segments, I, I, from being engaged prematurely by the
tooth, h, a spring bolt, I, is employed which engages the front end of the segment
and in effect pushes it back until its rear end abuts against one of the pins, z8 or 1³.
As soon as this occurs the continued movement of the cylinder will cause the segment
to force back the spring bolt and pass by it, and then continue to move without
interference. The construction and operation of the segments are similar to those
employed in the prior Nelson machines, but in those machines .no provision was
made for stopping the cylinder during the formation of a rib.
The pattern cylinder is provided with guide grooves at its opposite ends and with.
guide grooves and patterns on its periphery for operating various mechanisms.
These will be described hereinafter in connection with descriptions of the mechanism.

page_text: in connection with which they are designed to operate. It will be understood that
it is not essential that the movable segments should be employed, the object of
using them is mainly to avoid the necessity of employing a very large cylinder. By
the use of the segments a comparatively small cylinder can be used which need only
be moved when fashioning or when operating switches or the like. It should be
understood also that the pinion, h, may be made to move the cylinder during a part
of the operation of forming the foot, leg, and rib, as well as during the formation of
the toe and the heel, but preferably the cylinder is allowed to remain stationary
during the greater portion of the time when the foot, the leg, or the rib is being
formed.
The needles, b, , are of usual construction and are connected with jacks, B2, B³,
which are provided with upwardly projecting lugs, 65, as usual. The needles are also
supported by swinging supports, M, and the needles on the back row have their jacks
mounted in supporting levers, N, pivoted on a shaft, m, carried by a frame, N³,
secured to the frame of the machine. The supporting levers, N, are operated by the
pattern cylinder. The front jacks are carried by supporting levers, N¹, pivoted on a
shaft, n¹, carried by brackets,. N³, secured to the front of the machine. The swinging
supports, M, are of usual construction and are supported by the longitudinal
bars, M, M, which may be withdrawn to allow the supports, M, to drop when it is
desired to reinove or replace one or more needles. The supporting levers, N, N¹, are
so constructed, as shown, as to hold the jacks up in proper line to reciprocate
correctly during the operation of the needles, but at times the supports are moved
in such manner as to cause the jacks to be depressed and their lugs, 65, to be moved
out of the path of the operating cains, The rear ends of the jacks of both the front
and back rows may be formed with teeth, be, adapted to engage with teeth, 67, on the
supporting levers, N, N³, to prevent the accidental movement of the jacks when they
are depressed. The supporting levers, N¹, are guided in slots in the frout needle bed,
and the supports, N, are guided in slots in the back needle bed, the frame, N2, is in
like manner slotted to guide the supporting levers, N. The levers, N, are provided
with triangular lugs adapted to ride on the periphery of the pattern cylinder, and in
grooves therein, in the usual way. In Fig. 5 the supporting levers, N, are shown in
position to hold the lugs of the jacks in position to be operated upon by the cams on
the slide C5. But when the levers are turned on the shaft, m, that is, when their
rear ends are elevated and their front ends depressed, the jacks will be depressed,
and the lugs, f, will be out of the paths of the cams. The supporting levers, N',
are operated to move the lugs, b, of the front jacks into and out of the paths of
the cams on the slide, C, in the manner hereinafter described.
The main yarn carrier, D, is mounted to slide on the top of two flanges, d¹, on the
upper ends of the two supporting frames, D³, D, of the ribbing needles. These
supporting frames are secured at their ends to brackets, D³, attached to the opposite
ends of the frame, A¹, of the machine. The flanges have a space between thein
through which the main yarn carrier projects, as indicated in Fig. 18. The top
plate, d², of the main yarn carrier which slides on the flanges, d, is secured to a
vertical plate, d³, that has on opposite sides flanges, , sliding in grooves, d³, in the
supporting frames, D³, D. An arm; De, projects rearwardly from the top plate, d²,
and is provided with a lug, d³, which extends into a notch, d, in the end of the
pitman, D. A yarn guide, D', provided with two passages for yarn is secured to
a plate, Ds, pivoted at d, to the arm, D. Yarn is fed through the passages, d³, in
the usual way, and the frame, D°, for operating the brushes that feed the yarn
forms no part of my present invention. The plate, D³, is formed with an exten-
sion, do, which is pivotally connected with a lever, Do, pivoted at du to the top
plate, d, and formed with a lug, di, adapted to move either between the flanges, d²,
or along the back side of the back flange, these movements being governed by the
position of the switch, D¹¹, pivoted to the rear flange d', at the right-hand end of the
rear flange, d, and connected to a crooked lever, d¹³, provided with a pin, d¹, entering
a groove, g', in the pattern cylinder.. The lever, 13, is pivoted at d to the right-
hand end of the machine, and the arrangement is such that at proper times the
•

page_text: switch, d¹¹, is shifted to cause the lug, d, to be transferred from the front to the back
of the rear flange, d', or vice versa, thus causing the plate, Ds, and consequently the
guide, D', to be shifted to bring one or the other of the two passages, ds, over the
eye of the yarn carrier through which the yarn is delivered to the needles.
The switch, D, is moved when the yarn carrier is at the limit of a stroke to the
right. It is never moved when the yarn carrier is in any other position. The switch
has inclined surfaces on opposite sides, and when the lug, 2, rides along oue of
these surfaces it causes the lever, D10, to move in one direction or the other, and thus
correspondingly move the yarn guide, D', to effect the change of yarns. The
passages, de, are connected with tubes, and d", extending down through a curved
slot, d, in the top plate, d, and through a cut-away portion or open space, d¹º, in
the vertical plate, d³. The tubes are guided also by a curved slot, d, in a plate
bridging the space, d. Horns, and, are employed for holding down the
needles as the yarn carrier reciprocates over them, so that the points of the latch
openers, d², will enter the hooks of the needles and open the latches.
The cutting mechanism for the yarn comprises a frame consisting of three bars, d², d
and . This frame is pivoted to move about a vertical pivot in the vertical plate, d³.
The lower horizontal bar, d25, has an enlarged bifurcated end provided with two knife
edges, e, e, which co-operate with stationary knife edges, et, e. The upper curved
bar, d carries a lug, e, arranged to travel between the flanges, d. The tube, 16,
is adapted to engage with the end of the bar, d, and to move it outwards when
passing by it in either direction so as to withdraw the knife edges, es, e, from the
knife edges, es, e. This occurs when the tube is moved in either direction by the
lever, do, and when thus moved outwards the bar, d, holds the lug, e, in line to
engage with a cam, es, on the front flange, A. The yarn guide, D', is shifted when
the yarn carrier is at the extreme right-hand end of the machine, and when at this
end the knife edges are separated and the thread to be cut is laid between the proper
knife edges. When the yarn carrier is moving to the left, the lug, e', engages the
cam, e, and the cutting frame is moved inwards, causing the knife edges to come
together and thus cut the thread which is to be thrown out of operation. In general
the operation of the yarn carrier, including the mechanism for changing the yarns,
is like that heretofore employed, but the yarn carrier used iu my improved machine
possesses some novel features which are hereinafter claimed.
A spring latch, D2, is pivoted to a bracket, D¹³, by a pivot pin 'd, at the
right-hand end of the machine to prevent the yarn carrier from moving too far to
the right. This latch may, however, be opened by hand to permit the with-
drawal of the yarn carrier whenever desired.
The yarn carrier is reciprocated back and forth by the pitman, D¹, in the manner
herein before explained during the operation of forming all portions of the sock
excepting the ribbed top. The pitman, D', carries a plate, D15, having an inclined
lower edge adapted to ride on the upper end of a lever, D, pivoted at d³, to the
right-hand end of the machine, and carrying at its lower end a pin, D17, entering a
groove, g, in the right-hand end of the pattern cylinder, G. This groove is of
the shape shown in Fig. 9. It is so formed that normally the upper end of the
lever, Die, is out of the path of the plate, D, so that the pitman may reciprocate
back and forth and always move the yarn carrier with it. The groove, g³, is, how-
ever, provided with a portion, y, which so moves the bell-cmnk lever, DI, as to
throw the upper end thereof into the path of the plate, D. When this occurs, the
pitman, D¹, is raised when the slides and the yarn carrier are at the extremity of
their movement to the right. The lever, D16, remains in this position during the
formation of the rib and therefore the pitman, D¹, will reciprocate back and forth
without moving the yarn carrier, D, inasmuch as the notch, d, will be raised above
the lug, de, at the end of each stroke of the pitman until it has moved to such an
extent as to prevent its engagement with the lug. The lever, D1, is only operated
at the cominencement of the formation of the rib and at the completion thereof..
The front main cam slide, C, carries on its under side four cams, J, J1, J and J³.
The cam, J, is formed on the end of a lever, j, pivoted at its opposite end, ♬, to the

page_text: slide near its left-hand end. This cam is provided with a laterally projecting plate,³,
sliding in a guide-groove, j³, and carrying a log, j, which is adapted to shift the cam, J,
in the manner hereinafter described. It is also provided with a lug, j, for a purpose
presently to be explained. The cam, J', is secured to the end of a lever, , which
projects through a slot, j', in the slide and extends along the upper side thereof.
It is pivoted at so that it may be raised and lowered to correspondingly raise and
lower the cam to move it into and out of operation. An arm, 78, of the lever, ³, pro-
jects through the slot, jo, and carries a lag, ³, operated as hereinafter described. The
cam, J², has no up and down movement, but is provided with a guide blook, 10, slid-.
ing in a guide, j. This cam has only a slight movement and is connected with a
tension bar, L, mounted on levers, I, connected with a shaft, L', carrying an arm, A,
provided with a screw, 13, bearing on the pattern cylinder. The cam, J³, is secured.
to the end of a lever, j, pivoted to the under side of the slide, 04, at 13. The
cam, J², is cut away at j, opposite the cam, J³, to permit the lugs, 65, of the jacks
to advance when moved forward by the cam, J. A bar, J, secured to the slide, C+,
extends from the cam, J, to the right-hand end of the slide and serves at times to
guide in a straight line the lugs of the jacks. The cam, J³, is used only for operating
the end needle at the right-hand end of the machine on the front side, and it operates
only when ribbed work is being made. The cam, J³, is out of operation (as shown in
Fig. 31) when the toe or the heel of the sock is being made, but when the foot or
leg is being formed the lever, j, on which the cam is formed acts as a guide to the
lugs of the jacks, as shown in Fig. 33. When forming the rib the cam, J, acts to
retract the needles, as shown in Fig. 35, when the slide is moving to the right. The
cam, J', is elevated and out of operation during the formation of the toe and heel.
When forming the foot and leg it is an advancing cam, as shown in Fig. 33, and
when forming the rib it acts both to advance and retract the needles, as shown in
Fig. 35. The cam, J2, has only a slight movement transversely to the movement of
the slides; during the formation of the toe or heel the cam is out of the path of the
jacks, as shown in Fig. 31. When forming the foot or the leg the left-hand end of
the cam acts to retract the needles when the slide moves to the left, as.
shown in Fig. 33, and it operates in a similar way when the rib
is being made, as indicated in Fig. 35. In order to change the position
of the cam, J, at the proper times, the lug, j, is made to travel either on the inside.
or the outside of a flange, 3, on the upper front bar, C. This flange is formed by
cutting a longitudinal groove, , on the under side of the upper part of the bar, C³.
This groove extends from end to end of the bar, but the flange is out away at 1
and this opening is controlled by a switch, 1. The switch is adapted to be shifted
from the position shown in Fig. 28 to that shown in Fig. 29. When the switch is in
the position shown in Fig. 28 the groove, 14, is closed at its left-hand end, and the
lug,, moves back and forth on the outside of the flange, thus holding the cam, J,
in the position shown in Fig. 33. But when the switch is in the position shown in
Fig. 29 the lug moves in the groove back of the flange, 1, and the cam, J, is held
in the position shown in Fig. 31. The switch, 16, is provided with an arm, , free to
oscillate in a groove 18, in the bar, C³, and it is pivoted at . The inner end of the
arm engages with the upper bifurcated end of a hell-crank lever, L, pivoted to the
machine at 10, and connected with a rod, 14, which is pivotally connected at its lower
end to the rear end of a shoe, 0, bearing on the pattern cylinder. The shoe, O, is
pivoted to a hanging bracket, Oio, secured to the frame of the machine at its front
left-hand end, as shown in Fig. 1. The pattern cylinder is formed with a groove, 10,
which is divided by raised portions, the arrangement being such that the lugs at the
front and rear ends of the shoe, O, are made to ride either on the groove or on the
raised portions of the cylinder. When the rear lag is in the groove the rod, L*, will
be depressed, and the switch, 10, will be open, as shown in Fig. 37. But when the
rear lug is on one of the raised portions the switch will be closed. The lug, j, of the
cam, J, is adapted to move in longitudinal grooves, [12, 13, above and below a rail or
flange, 4, on the front guide bar, C². The grooves are always open at their right-
hand end, but at their left-hand end they are controlled by a switch, L³, pivoted at 714

page_text: to the left-hand end of the rail or flange, 1". At 16 the switch is connected with a
rod, I, extending through a guide opening in the bar, C, and connected at its lower
end to a shoe, 0, which bears on the pattern cylinder and is controlled by a groove, 11,
therein. The shoe, O¹, is shaped similarly to the shoe, O. When the front end, of
the shoe is elevated, as shown in Fig. 36, the switch, L, is elevated and the groove,
is closed and the lug, jo, is caused to travel in the lower groove, 18, thus holding
the cam, J, down and in operation, as shown in Fig. 33. When the switch, L,
is shifted to the other position the lug, j, travels in the upper groove 12,
and the cam is elevated and out of operation, as shown in Fig. 31.
The cam, Js, is adapted to be elevated or depressed so as to move in either
of the grooves, 117 or 18, on opposite sides of the rail or flange, (19. At the
right-hand end of the rail, 18, is secured a spring switch, 20. When the cam, J³, is
moving in the under groove, and its edge, , strikes the switch, 120, it elevates the
switch and passes by it, the switch springing back automatically into the position
shown in Fig. 33, when the cam has passed. On the return movement to the left
the cam rides up over the switch, 10, and into the groove above the rail or flange, 11,
until it reaches the left-hand end of this groove. If the rib is being formed, a
switch;, will be in the position shown in Fig. 35, and the cam, J³, will strike against
its inclined end and move downward into line with the lower groove, 18, which it
traverses on the return movement to the right. Thus, during the formation of the
rib, the cam, Js, will be raised or lowered at the end of each stroke. When travelling
to the right it will always travel in the lower groove and will thus be in position to
act upon the end needle. When travelling to the left the cam. will always be in the
upper groove and will be out of line with the end needle, and therefore will not
operate it. When the machine is not forming the rib, the cam, J³, will always move
above the rail, 1, and consequently will not operate the end needle. The switch, *, is
pivoted at 123 to the inner grooved side of the lower front bar, C, and it is connected
at (, to a rod, L', sliding in the guide opening. 5, and at its end connected with
the shoe, O2, pivoted at o to the bracket, O10, and bearing on the pattern cylinder.
The shoe, O, is similar in shape to the shoes, 0, 0, and it is adapted to work in a
groove, 12, in the pattern cylinder and on raised portions interposed in the groove,
the pattern being such as to operate the switch at the proper time. Fig. 8 represents,
as accurately as can well be shown in a drawing, the shapes of the grooves, 10, 11
and 12. The shoes, 0, 0¹, and 0%, are shown in Fig. 8 in the positions they occupy
relatively to the grooves.
The lug, j, of the plate, 7, is adapted to enter a groove, 1, formed between the
upwardly projecting flange, l, of the tension bar, L, and the edge, * of the
bar, C³.
When the parts are in the position shown in Fig. 31, the lug, x, travels in
the groove, *, and the tension bar, L, holds the cam, J, in contact with the
cam, J²,
so that when the cam, J2, moves for tension, the cum, J, will be moved also; but
when the cam, Ja, moves back it does not shift the cam, J, but the latter is shifted
by the tension bar, L, which operates on the lug, jx. When the parts are in the
positions shown in Fig. 33, the lug, j, travels outside the edge of the har, L, and
this bar does not operate on cam, J. The groove, 1, is much wider than the lug, j,
so that the cam, J, can shift when the lug is in the groove.
The back cam slide, C5, carries five cams, K, K1, K2, K3 and K. The cam, K, is
provided with a guide block, k, sliding in a guide, k. It is connected with a tension
bar, K, carried by arms, K, secured to a shaft, K', to which is attached a shoe, K³,
working on the pattern cylinder. The tension bars are connected by a spring, K³,
and are operated in substantially the same inanner as in the prior Nelson machines.
The screw,
12, of the front tension bar operates on the periphery of the cylinder and
in grooves, 15, therein. The shoe, K³, operates on the periphery of the cylinder, but
at a certain time in the operation of the machine it drops into a recess, 16, so as to
vary the tension. The periphery of the cylinder may also be formed with proper
elevations and depressions, other than the recess, 16, to regulate the tension. The
cam, K, is a stationary cam. The can, K¹, is secured to the end of a lever, k³,
pivoted to the slide, C. An arm, ³, of this lever projects through a slot in the
✓

page_text: and
in
alide and carries a lug,, which operates in grooves, k³, k³, above and below a rail k³,
in, the inner side of the back lower, bar, C. At their left-hand ends the grooves are
opened and closed by a switch, 126, pivoted at the end of the rail, k³, and provided
with a pin, 1, which extends through an opening in the bar, C, and connects with
a rod,, which extends through a guide opening, and at its lower end is connected
with a shoe, 04, similar in construction to the shoes, 0, 0, etc., and pivoted to the
rod, m. It is adapted to bear on the pattern cylinder which is provided with
a groove, 14, which controls its movements. The shoe is adapted to move
either on the periphery of the pattern cylinder or in the groove. When
its, front lug is in the groove, the back Ing is on the periphery of the
cylinder, and vice versa. In this way the switch, 1, is raised and lowered.
The cam, Ks is formed on the end of a lever, k³, pivoted at k to the under side
of the slide, C, near its right-hand end. This cam is provided with a plate, 10,
guided in a groove, kl, and carrying a lug, 2, extending through a slot, ¹³,
arranged to move on the opposite sides of a flange, k, in the upper back bar, c. It
is also provided with a lug, k, for a purpose hereinafter specified. The groove in
rear of the flange, 14, is opened and closed at one end by a switch, L³, pivoted at m10
and connected, as shown in Fig. 39, with a shoe, 0s, carried by the rod, m, and
operating in a groove, 13, in the pattern cylinder, and on raised portions of the
cylinder between portions of the groove the arrangement being snch that the ends of
the shoe are raised or depressed at the proper times to correspondingly shift the
switch, IF. The shoe, 0, is similar to the shoes, 0, 01, 0%, and operates in
substantially the same way. In Fig. 28 the switch, L³, is shown in such position as
to close the groove in rear of the flange, 4, and thus the lug, k, is made to travel
on the outside of the flange. In Fig. 29 the switch is shifted so that the lug, k¹³,
will travel in the groove in rear of the flange. When the switch is in the position
shown in Fig. 28, the cam, K³, will be in the position shown
Figs. 30 and 32, and when the switch, L³, is in the position shown in
Fig. 29 the cam, K³, will be located, as indicated in Fig. 34. The cam, K', is secured
to the end of a lever, k, pivoted at 1 to the slide, C. It is adapted to slide back
and forth in grooves, 7, 18, above and below a flange, 19, on the lower back bar, C².
At one end of the rail, k¹, is attached a spring switch, ml, indicated in Fig. 34. This
switch is similar in construction and operation to the switch, 120, on the front side of
the machine. At the right-hand end of the grooves, 117, 118, is secured a stop, k²,
having an inclined edge facing the grooves. The cam, K', by this arrangement will
be raised or lowered at the end of each stroke during the entire operation of the
machine, but the support for the jack of the end needle at the left-hand end of the
back row of needles is so controlled by the pattern cylinder that the end needle is
only actuated by the cam, K', when ribbed work is being made; therefore no special
switch mechanism is required to control the movement of the cam, K'. When
travelling to the right, the cam, K+, rides in the upper groove, . It then strikes
against the stop, . On the return movement to the left, the cam rides in the
groove, 18. When it reaches the switch, m, it raises it, passes by it, and on the
return movement enters the groove, 17. It will be understood that the cams, J³ and
K*, are not provided with lugs to operate in the guide grooves, but the rear edges of
the cams themselves travel in the guide grooves. It should also be understood that
the cams, J, K, are not arranged to operate on the jacks of any of the needles except
one end needle in each row of needles, the jacks being specially formed to be acted
on by the cama, as hereafter explained. A rail, K³, secured to the back slide on its
under side and extends from the can, K¹, to the left-hand end of the slide. A guide
rod, 20, is pivoted to the side of the rail, K, and is secured to the lever, ³, by a
pin,, which exfends through the rail,, the arrangement being such that as the
cam, K³, is elevated the end, 22, of the rod is depressed, and vice versa. This is for
the purpose of guiding the jacks when the cam, K¹, is out of operation.
The shapes of the several cams and their exact relative positions at various stages
of the knitting are clearly shown in the drawings, especially in Figs. 28 to 35,
inclusive.

page_text: When knitting the toe of a sock, the front and back cams are arranged as shown
in Figs. 30 and 31. The cams of the front slide are all out of operation, and the
needles are withdrawn. The cam, K4, is moved up and down at the end of each
stroke, but as the end needle is thrown out it does not operate it, nor does it touch
the lugs,, of the other needles. The cam, K³, lies close to the cam, K², and the 5
Jugs, 6, of the jacks are in contact with the edge of the lever, 8. The cam, K³, is
also lowered and active. When moving to the right the cam, K, operates as a retract-
ing cam, and the cam, K¹, as an advancing cam. When the slides move to the
left this can, K, retracts the needles, and the cam, K2, advances them. In this
way a course is knitted during each stroke or twice during each reciprocation or double 1
stroke of the Blides.
Figs. 32 and 33 show the positions of the cams when knitting the foot or the
leg. The cam, J', on the front slide advances the needles when the slide is moved
to the right, and when moving to the left the cam, J2, retracts them. The
cam, K, on the back slide retracts the needles when the slide moves to the right. 1
When the slide moves to the left the cam, K³, advances the needles. The cams
remain in the positions shown in Figs. 32 and 33 during the entire operation of
forming the foot and the leg.
When formning the rib the cams of the front and back slides are in the positions
shown in Figs. 34 and 35. When the slide moves to the right, the cam, J¹, advances
the needles, and the cam, J, retracts them. When moving in the opposite direction
the cam, J¹, advances the needles, and the cain, J2, retracts them. The cam, J³,
acts on the end needle, and gives it an additional movement.
The lug, k, on the plate, 10, is adapted to enter a groove, a, formed between
the edge of the har, C, and the flange, a21, of the tension bar, K³. When the
parts are in the positions shown in Fig. 34, the lug, k, travels in the groove, 20,
and the tension bar, K³, holds the cam, K³, in contact with the cam, K, so that
when the cam, K, imoves for tension, the cam, K³, will be moved also, but when
the cam, K, moves back it does not shift the cam, K³, but the latter is shifted by
the tension bar, K³, which operates on the lug, k*. When the parts are in the
positions shown in Fig. 30, the lug, k, travels outside the edge of the tension bar,
and the bar does not operate the cam, K. The groove in rear of the flange, k",
is much wider than the lug, 2, so that the cam, K³, can shift while the lug is in
the groove.
The pattern cylinder and the connections between the tension bars and
the pattern cylinder are such as to impart the proper tension to the cams while
knitting the several parts of the stocking.
The jack of the end needle is indicated at Y. The shape of the jack is shown
clearly in Fig. 25. It will be seen that in addition to the lug. 6, the jack has an
additional lug, 6, the arrangement being such that the main knitting cams are
adapted to operate on the lug, b, while the cam, Js, or the cam, K', is adapted to
act on the extension or additional lug, 65.
Referring now to Fig. 35, when the slides move to the right the advancing end of
the cam, J³, will operate upon the end of the extension. 6", and advance the jack, Y,
the lug, b', entering the recess, j, of the cam, J. As soon as the cam, J³, has
passed the extension, b", the lug, b', will strike against the end of the recess in the
cam, J, and the inclined end, b, thereof will move the jack backwards. Immediately
thereafter the cam, J', comes in contact with the lug, 6, and advances the jack, Y,
and next the cam, J, acts to retract the jack. In this way it will be seen the end
needle is advanced twice and retracted twice during the movement of the front slide
to the right. When the slide moves to left, the cam, J, will be above the rail, 1,
and consequently out of operation. The purpose of giving to the end needles the
additional movements will be hereinafter explained.
Referring to Fig. 34, when making the rib the cain, K, of the back slide advances
the needles when the slide is moving to the right, and the cam, K, retracts them.
When moving in the opposite direction, the cam, K³, advances the needles, and the
K³, retracts them. The cam, K, operates upon a jack similar to the jack, Y,
shown in Fig. 25. When moving to the left the cam, K, acts on the end of the
Caul,

page_text: lug, 6", and advances the needle. Cam, K, then retracts the needle (by acting on
the lug, b'), next cam, K', advances the needle, and then the cam, K, retracts it.
When the slide is moving to the right, the cam, K, is in the upper groove, ¹ and
therefore does not operate upon the jacks.
The ribbing needles, P, are pivotally mounted on bars, Q, which extend through
openings in the supporting frames, D3, D4. These frames are formed with a series of
slots, q, to permit the needles to oscillate transversely across the central longitudinal
openings between the needles. The bars, Q, are stationary and the needles have
independent pivotal movements thereon. Each needle is formed with a central
bearing portion, q, through which its supporting bar, Q, extends, and an upwardly
projecting arm 93, which extends above the top of the frame, and with a downwardly
projecting portion or shank, q, to which the needle proper, 95, is connected. The
heel of the needle is curved forming a recess, 98, and it is formed with a hook and
latch, of usual construction. The needles are so pivoted that those on one side of
the machine can pass over to the other side thereof, in the manner illustrated in
Figs. 46 and 47. The shanks extend through slots in guide bars, P', which are
mounted to slide longitudinally of the machine in guide grooves p³. These slotted
hara are for the purpose of guiding the lower ends or shanks, q, of the needles, and
to keep them in proper line. The slots are widest at their rear ends and the
portions, p, in front of the rear wide portions of the slots form resting places for the
Dain knitting needles when the ribbing needles are out of operation. Furthermore,
the ribbing needles when out of action are locked in the wide portions of the slots.
When the main portion of the sock is being knit the needles when they are advanced
project above the bars, P, and their hooked ends rest thereon, those opposite the
ribbing needles resting at the points, p³. When ribbed work is being made the
needles that formerly rested at these points, 23, are thrown out of operation, and
the bars, P¹, are shifted, bringing the open slots in line with the ribbing needles to
permit them to oscillate. The bars, P¹, are slotted at pt, and through these slots
extend rods, p³, pivotally connected at their lower ends to a link, pe, which in turn is
connected with a lever, p', pivoted at på to the frame of the machine, and carrying a
pin, p', which works in a groove, po, in the left-hand end of the pattern cylinder.
This groove is so formed that it holds the bars, P¹, in the position shown in Fig. 22,
at all times except during the transferring operation, and during the formation of
the rib. At the commencement of the transferring operation the pin, pa, rides along
the incline, p, of the groove and shifts the bars, P¹, permitting the needles to
oscillate freely. During the formation of the rib, the pin, p", rides in the
portion, po, of the groove when the pattern cylinder is being moved, and at the
end of the ribbing the pin, po, rides in the inclined portion, pis, of the groove and
the bara, P¹, are shifted back to the position shown in Fig. 22. The rods, ps, which
pass through the slots, p, in the bars, P¹, are formed with notches, p¹³, the inclined
edges, p, of which operate to shift the bars, P¹, at the proper times.
The ribbing needles are locked, except during the formation of the rib, by
toothed bars, P³, (see Fig. 24). Each of these bars slides in a longitudinal groove
in one of the frames, D3, D4, and a lug, p, on the bar extends into a recess ple,
in a rod, p, which is recessed at p18 and these recesses are engaged by the
recessed ends pl, of the rods, p, the arrangement being such that as the rods, p².
are raised and lowered, the toothed bars, Ps, are shifted. The teeth are so disposed
that at times they lie in the slots, q¹, behind the ribbing needles, and hold them
securely in the position shown in Fig. 22. But when the bars, P³, are shifted.
the teeth clear the slots, q', and the needles are permitted to oscillate transversely.
Without some such provision for locking them, the ribbing needles might be shaken
out of position so as to interfere with the operation of the main knitting needles.
The toothed bars are also so constructed and arranged that when slid in one
direction they will operate to nove the knitting needles from the position showi
in Fig. 47, for instance, back to the position shown in Fig. 40. This operation occurs
after the ribbed top has been finished, as will be hereinafter described.

page_text: Parallel guide bars, R, are mounted in brackets, r, at opposite ends of the machine.
These bars are arranged on opposite sides of the needles and above the plane of
the bars, P¹. They have an axial movement which is effected by levers, R¹, R,
having pins, 7, 2, extending into a groove, ³, in the right-hand end of the
pattern cylinder, and connected by links, 4, 5, to brackets, R, R5, secured to the
right-hand ends of the guide bars. The groove, r, is clearly illustrated in Fig. 9.
For the most part it is plane or concentric with the axis of the pattern cylinder,
but at it is so formed as to act upon the pine, 1, 3, to properly move the
levers, R¹, R², to give proper axial movements to the guide bars, R, which movements
are hereinafter explained. A description of the precise formation of the groove
seems unnecessary, as the groove is accurately shown in the drawings.
The yoke, c, extends across the guide bars, R, and to this yoke are hinged
levers, 8, carrying cams, S, S', adapted to act on the upper ends of the arms, q³, of
the ribbing needles. Each guide har, R, carries a sleeve, S² (Fig. 13) which has a
feather and groove connection with the bar, and is free to slide therein and to turn
therewith, both bars being grooved from end to end for this purpose. The yoke, c¹,
carries recessed blocks, 7, entering recesses, s, in the sleeves, S³, and as the yoke is
reciprocated the sleeves are correspondingly moved along the bars, R. Each
aleeve, S², carries a slotted arm, 8³, extending through a slot, s, in the lever, 8.
When the bars, R, are turned in one direction, the arms, 83, will hold the cams, S, 81,
elevated and out of the paths of the ribbing needles, but when these guide bars are
turned in the opposite direction the cams are lowered and held in the paths of the
needles and act upon them to move them out of the position shown in Fig. 40 into
the pat bs of the cams that operate them while knitting the rib. The slots in the
arms, 43, are so formed that the cams, S, S¹, are held up and out of operation except
when they are used to move the ribbing needles into operative position. When the
arins, 63, are lowered the cams, S, S', drop into the paths of the ribbing needles, but
the slots are so formed that the bars, R, can have a further axial movement without
further tending to move the cams, S, S¹. The operation of these devices will be
further explained hereinafter.
There are two yarn guides, T, T', for feeding yarn during the operation of forming
the rib. They are practically the same in construction and are free to slide back and
forth on the guide bars, R, and to turn relatively thereto as well as to permit the
bars to have an independent axial movement. The tube, t, of each yarn guide
through which the yarn is fed is connected with a sleeve, t, on the guide bar, R.
The latch openers, 2, are carried by a plate, t³, provided with sleeves, t,, mounted
on the bar, R. The sleeve, t¹, is arranged between the sleeves, and tº, and bas a
slight movement between them at the end of each stroke, as illustrated in Fig. 21.
An eye, to, which may be made of wire is secured to the sleeve, t. The tube, t,
abuts when moving in one direction against a block, 17, on the plate, ts, as shown in
Fig. 21. These yarn guides are held down by the frames D and D, and slide along
the guide heds, T, as indicated in Fig. 18. At the right-hand end of the machine
the guide beds have sunken or depressed portions, tio, connected with the main
portions, T, by inclines, (". The purpose of this arrangement is as follows: When
the yarn guides, T, T¹, are in operation the main yarn carrier, D, is at rest at the
right-hand end of the machine, as shown in Fig. 18, but when in this position its
lower end, including the latch openers, d, etc., are in the path traversed by the
yaru guides, T, T¹, when feeding yarn to the needles, and consequently the yarn
guides, T, T, would strike against these devices of the yarn carrier, D, if the yarn
guides, T, 1", continued to move in the same path, but by causing the
yarn guides, T, T¹, to drop into the depressed portions, to, they will clear the yarn
carrier, 1, and operate without interference. On the return movement to the left,
the yaru guides, T, T₁, rise on the inclines, t, and therefore move in proper line
upon the guide beds, T².
The cam slides, U, for operating the ribbing needles are mounted on the guide
bars, R, on opposite sides of the machine. Each slide is formed with two
sleeves, u, u¹, adapted to slide on one of the guide bars, and the sleeves, t, t, t, of

page_text: the yarn guides are arranged between the sleeves, u, u¹, the arrangement being such
that the yarn guides are allowed to turn on the bars relatively to the cam slides to
move them with the slides as they reciprocate, having but a very slight independent
movement, which is allowed by a space between the opposing ends of the sleeves, t^, to,
and the sleeves, u, u¹. Each of the slides carries two cams, U³, U³, secured to the
end of a lever, u*, centrally pivoted at w, to the slide. The shape of the cams is
shown in Fig. 15. The lever, u², carries two laterally projecting pins, u, us, on
opposite sides of the pivot, u³, which are engaged by a sliding rod, Ut, having
recesses, forined with inclined sides engaging the pins, u, us, the arrangement
being such that as the rod, U, is reciprocated it acts on the pins to alternately raise
and lower the cans, U, US. The rod, U, is properly guided in a recess on the top
of the slide next to the sleeves, t, ², and a spring, u, guides one end of the rod and
holds it in proper alignment. A plate, U³, pivoted in rear of the cams, U2, U³, at its
ends carries guide flanges, u, us. It is also provided with laterally projecting
lugs, u, ulo, carrying pins, u, u¹³, projecting over the rod, U, and adapted to be
operated by the inclined sides of the recesses, ; the arrangement being such that
when one of the cams is elevated the adjacent flange, u, or us, is depressed. This
is for the purpose of guiding the ends of the arms of the ribbing needles with which
the cams engage, so that the arms will follow the proper courses in the ways between
the cams and the edges of the stationary plates or cams, U, U7, U, U, secured to the
under sides of the slides. The paths which the needles traverse are indicated by
arrows in Fig. 15. At the end of the movement of the slides to the right the rods, U4,
strike against stops, u, u, on the brackets, R, R³. This causes the rods, U*,
to be shifted to the left in such manner as to depress the cams, U³, at the
right-hand end of the slides, and to raise the cams, U2, at the opposite ends,
at the same time. raising the flanges, u', at the right hand end of the slides, and
depressing the flanges, us at the left-hand ends." At the end of the movement
of the slides to the left the cams and flanges are similarly operated to cause the
cams, U, to be depressed, and the cams, U³, to be raised and their
corresponding guide flanges similarly moved. The rods, U, however, do not
strike against stops at the ends of the guide bars, R, inasmuch as the yoke, c¹,
is in the path of the rods. The rods, U, are, however, arranged to strike against
slide rods, u, that are adapted to move back and forth in the blocks, r². The left-
hand ends of these slide rods strike against stops, 17, 18, on the brackets, r, at the
left-hand end of the machine, and when these rods are arrested they serve as stops.
for the rods, U4, and cause them to shift properly to change the positions of the
cams, U³, U³, and the corresponding guide flanges. The sleeves, $, are provided
with hooks, 85, adapted to engage with hooks, s, on the sleeves, u, u¹. It will be
remembered that the guide bars, R, are adapted to be first turned sufficiently to allow
the cams, S, S¹, to drop into the paths of the ribbing needles. At the proper time
the bars, R, are further turned and the hooks, &, are caused to engage with the
hooks, s', so that the sleeves, S² and u, u¹, wiil he looked together and as the yoke; c',
travels back and forth across the machine the oam slides, U, U¹, and the parts con-
nected therewith are reciprocated with it. The operation of this mechanism will be
further described when describing the operation of the entire machine.
Two bars, V, extend through slots, 8, and recesses, n², in the jack supporting
levers, N¹. One of the bars extends through a recess, 2, in each alternate jack,
and through a slot, n³, in the other jacks, while the other rod, V, in like manner
extends through recesses in each alternate jack and through slots in the remaining
jacks, the arrangement being such, as indicated in Fig. 25, that when one of the bars
is elevated or depressed it will elevate or depress each alternate supporting lever or
one half of the supporting levers, while the others remain stationary. The bars, V.,
are connected at their ends to upright rods, V2, which extend through guide
openings in the frame of the machine and at their lower ends are connected to the
front ends of shoes, 0%, (see Fig. 1), bearing on the pattern cylinder and in
grooves, 17, therein; the arrangement being such that at proper times the bars,. V₁

page_text: are independently operated to raise or lower one-half of the supporting levers, N¹,
to cause the corresponding jacks, B2, to be thrown into or out of operation.
The pattern cylinder is so formed as to cause the supporting levers, N, of
the jacks of the back row to be shifted to throw corresponding jacks into and out of
operation. When passing from plain knitting to the knitting of the ribbed top the
supporting levers, N, N1, are operated to throw one-half of the jacks (each alternate
one) on each row out of operation, the needles of these jacks being supplanted by
special ribbing needles, as hereinafter described.
Each alternate jack on both the front and back side of the machine has on each
side a transferring point, W, the form and arrangement of which are shown particu-
larly in Figs. 25, 26 and 27. The front ends of the points are iuclined and on their
inner faces are formed recesses, 10, to receive the hooked ends of a ribbing needle, as
indicated in Fig. 27. The shanks of the transferring points extend rearwardly along-
side of the jacks, B³, above the rods, V. Each transferring point in both front and
back rows, is formed on its upper edge with lugs, c¹, between which extends a
longitudinal bar, W, connected at its ends to vertically arranged levers, W², that are
connected at their lower ends to sleeves, W³, surrounding the shafts, L, K. These
sleeves are provided with arms, W, W, carrying pins, w, w³, entering a groove, w²,
in the left-hand end of the pattern cylinder. This groove is for the most part
concentric with the axis of the cylinder, and when the pins, 102, 103, move in this
concentric portion of the groove the bars, W₁, are so held as to hold the transferring
points in their retracted positions. The groove, to, is, however, provided with
branches or offsets, w³, w, into which the pins, w², s, are adapted to enter. These
offsets of the groove are so shaped that they cause the bars, W1, to he first advanced
a short distance, then advanced to a greater extent, and subsequently to be with-
drawn to their original positions. The details of the mechanism for operating the
transferring points on both the front and back sides of the machine are clearly
indicated in Figs. 5, 6, 25, 26 and 27. Some of the parts are also shown in other
figures of the drawings.
The machine thus constructed and organized is specially adapted for knitting socks,
but with certain modifications it might be used for knitting other articles. The
ribbing mechanism might obviously be used separately from the other mechanism.
It may be arranged to make either plain or tubular work; that is to say, my inven-
tion comprehends the mechanism hereinafter claimed, whether used in a machine for
making socks or other knitted articles. In order to more fully understand the con-
struction, organization and operation of the machine herein shown, I will describe the
operation of the machine as organized for knitting socks throughout the entire process
of knitting a sock.
In commencing the knitting the "set up" is made as in the prior Nelson machines,
the cams on the front and back slides being in the position shown in Figs. 30 and 33.
As soon as the "set up" is made, the front row of needles is thrown out of operation
and the toe is knit on the back side of the machine. The cams on the back
slide being in the position shown in Fig. 30, while those on the front slide are
all out of operation, as indicated in Fig. 31. The main yarn carrier is actuated
in the usual way by the mechanism hereinbefore described during the formation
of the "set up" and the toe, and the pinion, h, operates on the teeth, h³,
included between the points, y, y, as indicated in Fig. 8, and also for a time
on the segment, 1. After the toe is completed, the cams on the front slide are
thrown into operation to co-operate with the cams on the back slide to form the
foot of the sock, the cams on the two slides at this time being in the positions
shown in Figs. 32 and 33, and the pinion, h, operating for the most part in the
space, 1, as indicated in Fig. 8. The tooth, ², on the pinion engages with the
segment, I', which is operated as herein before described. After the foot is completed,
the pinion, h, again engages with the teeth, h³, between the points, y³, y², to form
the heel, during which operation the cams on the front slide are out of operation, as
shown in Fig. 31, while the cams on the back slide are in the positions shown in
Fig. 30. Soon after the heel is completed, the pinion, h, enters the space, 2, and the

page_text: tooth, h³, on the pinion engages the toothed segment, I. When the pinion is arranged
in the space, 2, and its tooth operates upon the segment, I, the cylinder ceases to
move. During the formation of the leg the cams on the front and back slides are
arranged, as shown in Figs. 32 and 33. The yarn carrier reciprocates continuously
during the formation of the "sot up," toe, foot, heel and leg, but is shifted at
certain times to change the yarns. I have shown the yarn guide, D', as provided
with two guide tubes for two yarns. For instance, if I use blue and white yarns,
one tabe may be used to guide the white yarn, while the other is used to guide
the blue yarn. The blue yarn may be used to form the "set up," and, as soon
as this is formed, the yarn guide, D7, may be shifted by the mechanism hereinbefore
described to sever this blue yarn and to bring the white yarn into position to be
fed to the needles during the formation of the toe. After the toe is completed, the
yarn guide, D7, is again shifted, the white yarn is cut and the blue yarn is fed to the
needles. In like manner, white yarn is used in forming the- heel and blue yarn in
forming the leg. The mechanism for changing the yarn is illustrated in Figs. 17, 18
and 19, and has been herein before fully described.
While forming the "set up," toe, foot, heel and leg of the sock, the front row of
jack supporting levers, N¹, are all elevated so as to hold the lugs, b5, of the jacks in
position to be acted on by the cams. The jack supporting levers, N, on the back of
the machine are operated by the pattern cylinder.
As soon as the leg of the sock is knit, the segment, I, abuts against a spring dog, I²,
and moves the cylinder forward. The pinion, A, then engages the teeth, h³, between
the points, y³, and y, and the operation of transferring from plain knitting to ribbed
work is performed. The first thing that happens in the transferring operation is that
when the main yarn carrier is at the left hand end of the machine and the main cam
slides are at the extremity of their movement to the left, the pattern cylinder is
moved and operates upon the shoes, 0%, to move one set of rods, V, connected with
them to shift the supporting levers, N³, of the jacks of the front row of needles
so as to cause one-half of them, namely, every alternate one, to drop out of active
position. While the jacks are withdrawn their teeth, be, engage with the teeth, b²,
of the supporting levers so that they will not be advanced when the other needles
advance. When the slides next move to the right each alternate needle in the front
row (namely, those not thrown out of position) is advanced through the loops of the
fabric carried by them. During this stroke to the right, the back row of needles
draws back and knits in the usual way. At the end of this movement to the right
the pattern cylinder moves, and the main yarn carrier is disconnected or thrown out
of operation by means of the lever, D16, and parts connected therewith, as before
described. At the same time the branch, w³, of the groove, w, at the left-hand end
of the pattern cylinder operates on the front lever, W, to move the transferring
points on the front side of the machine part way up and into the position shown in
Fig. 40. At the same time one-half (each alternate one) of the jack supporting
levers, N, on the back side of the machine are moved to throw one-half or each
alternate jack of the back row out of operation, and the switch, 12, is shifted.
When these operations have been perforined, the cam slides move to the left
and the needles of the front row, which were not thrown out of operation,
are drawn down and leave their loops on the front transferring points. At the
same time each alternate needle on the back side of the machine rises. While at
the extremity of the movement of the slides to the left, the pattern cylinder will
again be moved, and the transferring points on the front side of the machine are
fully advanced and they carry the loops of the fabric away from the front needles, as
indicated in Figs. 27 and 41. At the same time the transferring points of the back
row are moved half-way up (see Fig. 41); also at the same time the front levers, N¹,
are dropped so that the front needles will not be advanced during the next stroke of
the cam slides to the right. During this same time, the bars, PI and P³, are moved
to their full extent, thus leaving the slots, q, free to permit the ribbing needles, P,
to oscillate, also bringing the slots of the bar, P¹, into line with the ribbing needles,

page_text: and the resting places, p³, into position for the main knitting needles which are to be
used in the process of forming the ribbed top. The lever, R², is also operated at this
time to turn to a certain extent the rear guide bar, R, so that it will cause the cam, S¹,
to drop into the paths of the upwardly projecting ends of the ribbing needles of the
back row.
At the same time the switch, 78, is moved to throw the cam, J, into
operation. After these operations have been performed, the slides move to the right,
the needles of the back row of main knitting needles draw back and the cam, S¹,
moves the ribbing needles of the back row through the transferring points of the front
row, as indicated in Fig. 42. When thus moving to the right, the needles of the
front row of main knitting needles do not operate, as the jacks were all dropped, as
above explained.
As soon as the slides have reached the end of this stroke to the right, the pattern
cylinder is moved and the back transferring points are fully advanced, and the front
transferring points are drawn balf-way back, as shown in Fig. 43. At the same time
the cam, S, is dropped into the path of the shanks, q, of the ribbing needles of the
front row and the switch, L³, is shifted. The cans on the back slide, C', are 'then
changed from the position shown in Fig. 32 to that shown in Fig. 34, and about this
time the end needle on the back row is brought into operation by the pattern cylinder.
At the same time the supporting levers, N, are all dropped so that the back needles
will not be advanced on the next stroke. The slides then move to the. left, and, the
front ribbing needles are moved by the cam, S, through the back transferring points,
as indicated in Fig. 44, and the front needles are inoperative, as the lovers, NI, have
all been dropped. When the slides are at the left, the pattern cylinder again moves,
the front transferring points are fully withdrawn, and the hack transferring points.
are withdrawn half-way, as shown in Fig. 45. Then the slides move to the right, and
as soon as they complete the end of their movement to the right, the pattern cylinder
again moves, the back transferring points are fully withdrawn, and both bars, R, R,
are turned so as to cause the hooks, s, to engage with the hooks, s, and the ribbing
cam slides will thus be connected with the yoke, c¹, and will travel back and forth
with it. Before the slides move to the left, the supporting levers, N, and N, on both
the front and back of the machine, are operated to hold each alternate needle in each
row in operative position, and each alternate needle in each row out of operation.
The transferring operation is now complete, and on the next movement of the slides
to the left a course of ribbed work will be made, the ribbing needles on the front side
of the machine co-operating with one-half of all the main knitting needles on the back
Bide, and the ribbing needles on the back side of the machine co-operating with
one-half of all the main knitting needles on the front side of the machine. In moving.
to the left on the first stroke after the slides, U, U¹, are picked up, the front row.of
main knitting needles rise and pull back and the ribbing needles on the back row
co-operate with them to form a course of ribbed knitting. Immediately. after the
front row of main knitting needles bave knit, and the ribbing needles of the back row,
have crossed over and gotten out of the way, the back knitting needles, rise and
draw back and in connection with the ribbing needles on the front. side, kuit..

course is knit on each side of, the machine.
at each stroke; in fact, knitting two courses simultaneously during one stroke
of the cam slides. The different movements of the transferring points and the
ribbing needles are illustrated in Figs. 40 to 47, inclusive. It will be observed by
reference to Fig. 46 that when the back yarn guide, T", is feeding yarn to the main,
knitting needles of the back row, it feeds the same yarn to the ribbing needles of the
front row,
the yarn guide travelling across the machine in rear of the back row of
ribbing needles. Similarly, when the front yarn guide, T, is feeding yarn to the
front row of main knitting needles, it feeds yarn to the back row of ribbing needles,
and the yarn guide as it travels back and forth operates in rear of the front ribbing.
needles, which are crossed over and moved out of the way, as indicated. While
knitting the rib, the main yarn carrier, D, remains stationary, at the right-hand;
end of the machine, and yarn, is fed to form the rib by the yarn guides, T, T.

page_text: As the yarn guides, T, T, have been dropped, this movement of the ribbing needles
and the main needles casts off the sock. While the main cam slides are at the left,
the jack supporting levers, N, N³, are moved to throw all the needles of both the front
and back row back into operative position ready to begin a new sock. This same
movement of the pattern cylinder shifts the cam, J. When at the end of the next
movement to the right the main yarn. carrier is picked up, the lever, D¹, having been
moved out of the way, the pitman, D¹, will therefore carry the main yarn carrier back
and forth, in the usual way. A new sock is then produced in the manner before
described. While at the end of this movement to the right, the switch,*, is shifted,
the slides then move to the left and the "set up" is formed. At the end of the
movement to the left, the pattern cylinder again moves and cams, J, J¹, are shifted.
The machine then proceeds to knit a new sook in the manner before described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I

8. In a knitting machine, the combination of the front and back sets of main

page_text: The cams, U, Us, are properly shifted at the end of each stroke, as hereinbefore
described.
In order to form a tubular rib it is necessary to interlock the yarn which knits one
side of the ribbed fabric with the yarn that knits the other side. To accomplish this
I operate the end needle at the right-hand end of the front side of the machine, and
the needle at the left-hand end of the back side of the machine in a special way.
These needles are operated in the manner indicated in Figs. 29, 34 and 35, and it
has already been explained how they are operated twice during each reciprocation.
The effect of this operation of the needles is illustrated in the diagrams, Figs. 49 to 55,
inclusive. Fig. 48 indicates the three yarns employed. The yarn used for forming
the rib on the back side of the machine is shown by full black lines. The yarn used
for forming the rib on the front side of the machine is shown by parallel lines, the
center being white, while the body yarn is shown by section lines.
Both
Referring to Fig. 49 the two yarn guides, T, T¹, are shown as moving to the right
towards the end needle, Z. In Fig. 50 the end needle is shown as having been
advanced, grasping the back yarn, Z10. Fig. 51 shows the next movement.
yarn guides have advanced to the right, and the end needle, Z, has been moved
forward, causing the back yarn, Z10, to pass behind the latch of the needle. The
presser hooks operate in the usual way to hold down the yarn while the needles are
being advanced. All the presser hooks except one of the end ones on each row is

raised and lowered once for each stroke of the cam slides.
hooks on each row is raised and lowered twice for each single stroke of the cam
slides, and this presser hook co-operates with the needle, Z, in forming the loops at
the end of the fabric. As before stated the needle, Z, is advanced and retracted
twice for each stroke in one direction of the cam slides, and therefore it is necessary
to give to the corresponding presser hook the double movement above referred to.
Fig 52 shows the next step. The yarn guide for the front side of the machine has
advanced and laid its thread in the open needle, shown in Fig. 51, and the end
needle, Z, has been partially drawn back, the yarn guide for the back thread having

guides move still further to the right, the end needle, Z, is drawn back and then
advanced, as shown in Fig. 53, forming a loop with the front yarn and interlooking
it with the back yarn. In Fig. 53, the yarn guides are shown at the limit of their
movement to the right. They next move to the left, and the front yarn is looped
around the back yarn and as the front yarn guide moves to the left it feeds to the
needles to form a new series of loops on the front side while the back yarn is passed
over to the fabric on the back of the machine and interloops therewith, as shown in
Fig. 54. The end needles at the two ends of the machine operate in the same
manner, and form the loops and join the buck fabric to the front fabric in the manner
illustrated in the diagrams, Figs. 49 to 54, inclusive.
Fig. 55 shows the manner in which the ribbed work joins the body or upper end
of the leg of the sook, and the manner in which the ribbed fabric on the back side
joins that on the front side. The manner of forming the loops, of closing the tube
at the two ends of the machine, and of joining the ribbed top to the leg of the sock
are so clearly illustrated in the diagrams that no further description seems
necessary.
As soon as the ribbed top is finished, the cam slides, U, U¹, are dropped when these
slides are at the right-hand end of the machine. At the same time, the toothed
bara, P³, are moved so as to move all the ribbing needles upwardly into the position
shown in Fig. 45; that is to say, part way up. The bars, P¹, are not moved at this
time. At this time the switch, L', may be shifted, and the rear end needle thrown
out of operation. The pattern cylinder is moved to cause these changes. Then the
main cam slides are moved to the left, and when they reach the end of their stroke
to the left, the pattern cylinder moves again, further moves the bars, P³, and this
further moves the ribbing needles and brings them into their inoperative position.
At the same time the bars, P¹, are shifted,

page_text: knitting needles, the two sets of ribbing needles, a yarn guide for feeding yarn to
the front row of main needles and simultaneously to the back row of ribbing needles
and another yarn guide for feeding yarn to the back row of main needles and to the
