COMPLETE SPECIFICATION.
Improvements in Knitting Machines.
I, WALTER HARRIMAN STEWART, of the Town of Franklin, in the County of
Merrimack, and State of New Hampshire, United States of America, Machinist, 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:
It is the object of my invention to provide improved means for rendering
inoperative a portion of the needles of a circular knitting machine for the purpose
of rendering it capable of producing what is commonly termed "heel and toe
work.
"
It is also the object of my invention to provide improved means whereby the
cam plate may be automatically changed from a rotary to a reciprocating motion.
It is also the object of my invention to provide improved means for automatically
reciprocating the cam plate in the knitting of heel and toe work.
It is also the object of my invention to provide improved means for controlling the
operation of the needles in widening and narrowing as when heel and toe work is
being knit.
It is also the object of my invention to provide improved means for automatically
changing the movement of the cam plate from a reciprocating to a rotary motion.
It is also the object of my invention to provide improved means for automatically
stopping the machine at predetermined times as when it is desired to change
yarns, &c.
It is also the object of my invention to provide improved means which may be used
in lieu of the stop-motion mechanism mentioned, whereby the speed at which the
machine is driven may be automatically changed, as when it is desired to pass from
regular circular knitting to widening and narrowing, or heel and toe work, in the
manufacture of stockings, and from work of the latter character to that of the
former.
It is also the object of my invention to provide an improved friction clutch
mechanism whereby one or the other of two pulleys may be connected with and
released from the driving shaft.
It is also the object of my invention to provide other improvements incidental to
those hereinbefore mentioned.
My invention will first be described in connection with the accompanying drawing
forming a part of this specification, and then pointed out in the claims.

friction-clutch mechanism. Fig. 20 is a vertical sectional view of the same. Fig. 21
is a perspective view of the split ring hereinafter described. Fig. 22 is a detail view
of the lever employed to expand the split ring, also referred to hereinafter.
The same letters of reference designate the same parts in all of the views.
In the drawings, having reference to Figs. 1 to 15 inclusive, A is the base of the
machine in which are set pillars B which support upon their upper ends the needle
bed C, which latter part or device is provided with radial grooves in which are
arranged two sets or series of needles DE, the former being what I term "long
needles" and the latter "short needles." F is the needle operating cam plate,
arranged to rotate on the needle bed, and provided on its outer edge or portion with
gear teeth, which are engaged by the teeth of a gear G on the inner end of a shaft H,
which shaft is provided with two pulleys II turning loosely thereon, and a hand
wheel J. Between the pulleys I is a clutch collar K splined on the shaft H so as to
turn the same but so as to be capable of being moved longitudinally thereon. The
pulleys I are provided on their inner sides with holes or recesses adapted to receive
the spring-pressed pins L in the ends of clutch collar K when said clutch collar is
moved into contact with either of said pulleys. In lieu, however, of this positive
clutch-mechanism, I may employ the improved friction-clutch mechanism hereinafter
described.
M is the main or driving shaft provided with a driving pulley N and two
pulleys corresponding to pulleys I on shaft H. Pulleys Ŏ may be supposed to
be belted to pulleys I, one of such belts being straight and the other crossed, so that
the direction in which the cam plate F will be driven will depend upon with which
pulley I the clutch collar K is for the time being connected, it being understood, of
course, that the rotation of the cam plate may be stopped altogether by moving
the clutch collar K to a position between the pulleys I where the pins L may not
engage either.
P is an arbor vertically supported in suitable bearings and provided on its upper
end with a lever or an arm Q which extends over the cam plate and in the path of a
pin R in said cam plate. The arbor P is also provided with an arm S which at its
free end engages or enters a groove in clutch collar K. At its lower end arbor P is
provided with a forked arm or finger T.
With this construction it will be seen that if arbor P should be rocked in its
bearings, clutch collar K would be moved on shaft H so as to be connected with either
of the pulleys I, or be disconnected from both.
U are brackets connected, with the stationary part of the machine provided with
ways for supporting and guiding the pawl-carrying blocks V and needle-supporting
chains W, one end of which is connected with said block V and the other with the
needle depressing and raising slides X. Y are rack bars arranged over the brackets U
and so as to be reciprocated in bearings Z.
The needle bed is provided with a circumferential guideway at a point beneath the
tails of the long needles, to guide the chains W and slides X, so as that the chains
may support the tails of said needles, or so as the slides may engage and depress or
raise the said needles, as the case may be.
a, Fig. 12 is a two-armed pawl shown in plan in Fig. 12, which pawl is pivoted to
the block V, and is operated upon by a spring b, so as that when said pawl is
moved or adjusted in a manner that will permit of one of its arms engaging the

page_text: notches of the reciprocating rack bar Y, it will be maintained in such position until
moved or adjusted so that the other arm of said pawl will engage the rack bar.
c is a bracket or support connected with the brackets U. and upon a stud d
connected with said support, a centrally fulcrumed lever e, which lever is pivotally
connected with the rack bars Y. A lever Y-shaped at its inner end is rigidly con-
nected at its outer end with lever e at the fulcrum point of the latter. g is a lever
arranged beneath the lever fand fulcrumed towards its outer end on the bracket c.
Said lever g is broadened at its outer end, on the sides or ends of which broadened
part are secured upwardly-projecting pieces or flanges with which are connected
springs i extending rearwardly and resting on or near the end of lever f. j are blocks
connected with lever f and arranged to operate between the projecting pieces or
flanges h. Both levers fand gare arranged to extend out over the cam plate, and
over a ratchet ring k supported upon and arranged to turn in a suitable circum-
ferential groove or bearing in the cam plate.
It will now be seen that by moving the inner free end of lever f back and forth,
the rack bars Y will be reciprocated in their bearings in opposite directions, that is,
one will be moved outward when the other is being moved inward; and that,
by moving the inner free end of the lever g in one direction, the corresponding end of
lever will be moved in the opposite direction, the latter lever moving or reciprocating
the rack bars.
and
I are brackets fastened to the bed of the machine, and serving to hold the cam plate
in place and guide it in its rotary movement. In one of these brackets is arranged
a vertically-movable pin m, the manner of moving which, and the function of which,
will presently be described. n designates a cam on the ratchet ring k and extending
one half way round thereon, o being a similar cam, arranged outside of cam n,
extending a little more than half way round on the ratchet ring. p is a short cam on
the ratchet ring k, upon which cam p may rest a pin 9, extending laterally inward
from one end of a lever fulcrumed on a stud s, the end of which lever ? is pivotally
connected with the pin R, set in a hole in the cam plate, a spiral spring t shown
in dotted lines in Fig. 2 being arranged in said hole and serving to press the pin R
upward when permitted so to do.
u is a bracket secured to the cam plate k and supporting in its'outer end a vertically
arranged pin, which is held pressed downward by a spring w connected at one end
with a bracket u and engaging, at its other end v, as shown in Fig. 5. r is a bracket,
similar to bracket u, and supporting the pin y, which is normally held down by a
spring z. Pin vis arranged to travel over cam n, and pin y over cam o in the
rotation of the ratchet ring k.
a¹ is a lever pivoted at its inner end to the cam plate F and having its free end
extending out over the brackets 1, the spring 6' coiled round the pivoted stud of said
lever and having one end fastened to the latter, and the other end secured to the cam
plate serving to hold the lever in a radial position with respect to the axis of the cam
plate. is the pawl pivoted to lever a¹, and held by means of a spring in engage-
iment with the teeth of ratchet ring k.
d¹ designates the yarn carrier secured to the cam plate, and e' is a ring having
a limited reciprocating movement on the cam plate, to which ring is secured the
sinker operating cam f' which devices have the usual functions and operate in well-
known ways.
2, 3, 4, 5, 6, 7 designate the needle-operating cams, the long needles being
projected and retracted by the cams 2, 4, 6, and the short needles moved in like
manner by the cams 3, 5, 7. Cams 2, 3 are secured to the slides g' operating radially
in the cam plate, and cams 6, 7 are secured to a similar slide h', this construction and
arrangement of parts being for the purpose of adjusting the cams to regulate the
throw of the needles. The slides g' and ' are secured in position in the cam plate by
means of set screws ¹, j', (Fig. 1).
designates a block which passes through bracket u, and is provided on its outer
end with a rounded stud . This rounded stud of the block k is arranged to rest

page_text: against the inner edge of the ratchet ring k and to operate in a cam slot m¹ formed by
a notch made in the ratchet ring, and a cam n' attached to the cam plate. o¹ designates
a block the upper end of which is pivotally connected with the inner end of block k¹,
said block o' passing down through a hole in the cam plate, and a slot in the inner
end of an angular block p¹, to which latter device said block is perfectly connected,
cam 5 being rigidly secured thereto.
Sufficient description has already been given for explanation as to how the operation
of the cam plate may be changed from a rotary motion, as when a tubular web is
being knit, to a reciprocating motion, as when heel and toe work is being performed,
and as to how the operation of the needles may be controlled.
The parts being in the position in which they are represented in Fig. 1, the pin m
is raised (this being accomplished automatically by means to be presently described),
the cam plate continuing to revolve in the direction of the arrow (Fig. 1) as before,
until the end of lever a strikes and passes pin m, which will result in moving ratchet
ring k around on the cam plate the distance of one tooth of said ring. This movement
of the ratchet ring effects three changes, which may be described as follows: First,
cam p is carried from under pin 9 as of lever r, permitting pin R to be raised by the
spring t thereunder. Second, pin v held down on the face of the ratchet ring k by
spring w will be raised by cam n passing thereunder. Third, the rounded end or
stud of block k¹ will pass out of the angular cam slot m¹ formed between cam n¹ and
the notch in the ratchet ring on to the inner edge of said ratchet ring, moving cam
block k inwardly, and through the medium of blocks o¹ the small raising cam 5, so
that said cam will not act upon the shanks of the short needles, thus rendering said
needles, which may be supposed to comprise one half of the needles in the circle,
inoperative.
It is to be understood that the parts are so timed as to effect these changes at a
time when and place where the needle operating cams are over and acting upon the
long needles, so as that when the cams reach the short needles they will not effect
them in any way..
Pin R being raised to such height as to cause it to engage the lever Qin the
rotation of the cam plate strikes and moves said lever, shifting clutch collar K, through
the medium of arbor P and arm S, disengaging said clutch collar from one pulley I
and connecting it with the other, and so reversing the course of movement of the cam
plate. As the cam plates move around in a direction opposite to the arrow Fig. 1, the
pin v, which was raised after it had passed the lever f, by moving in the direction of
the arrow now enters the Y in said fever and moves it to one side moving one rack
bar Y outward and the other inward, the outward moving rack bar moving the
chain W with which it co-operates out through the medium of the pawl attached to its
block V, a distance sufficiently far to cause the connected slide X to depress one of
the long needles, and the inward moving rack bar moving to an extent sufficient to
cause the pawl on the block of its co-operating chain to engage an advanced notch in
the rack bar.
The cam plate continuing to revolve in the direction opposite to the arrow Fig. 1,
pin R will be brought again into contact with lever Q, effecting the reversal of the
movement of the cam plate, and the movement of the lever f by pin in a direction
opposite to that it was before moved, and this operation will be kept up until
ratchet ring will have been turned substantially one-half way round, when pin v
will ride off of cam n on to the face of ratchet ring k, at which instant pin y in
bracket will ride up on to bracket o. Simultaneously with this operation the
arm of each pawl on the pawl carrying blocks V which is engaged with the teeth
or notches of the rack bars will be brought into engagement with a lug 83 on
the side of the rack bar, with the effect of reversing the position of said pawl, so that
further reciprocating motion of the rack bars will result in moving the chains back or
inward, and raising the needle at each inward movement. The operation will continue
as before excepting that lever finstead of being moved by operation of pin v thereon
will be moved through the medium of a lever g acted upon by a pin y on cam o.
The

page_text: reason for this manner of operating lever fis for the purpose of effecting the raising
or bringing into operation of a needle after it has been passed by the needle-operating
cams and just before the cam plate is reversed in its movement, and so, as it were,
wrapping the yarn around the added needle, in order to effect "close joining" along
the line where the needles are thrown out of and brought into operation.
For a fuller understanding of this operation and its effects particular reference may
be had to Figs. 1° and 1°. When the new or added needle, 23, before the yarn-guide
and needle-operating cams reach the same, the yarn will be laid upon such needle as
shown in Fig. 1ª and when said new or added needle, 23, is not brought into operation
until after the yarn-guide and needle-operating cam has passed the same, but before
the cam plate is reversed, such new needle will be projected over the yarn, so that as
it comes back it will be laid upon and wrapped around the needle 23, as shown in
Fig. 1. The result in the first instance will be to leave eyelet holes, so-called, while
in the latter instance close knitting will be obtained.
After the ratchet ring has effected a complete revolution, and is brought into the
position in which it is represented in Fig. 1, it may be supposed that chains W will
have been moved fully inward by the action of the rack bars upon their attached
pawls, the rounded part 1 of the block will have been acted upon by cam n¹, to
depress cam 5 through the medium of the described intermediate devices, pins R,
v and y will have been depressed, pin m drawn down, and the knitting of the heel or
toe completed, when the cam plate will be revolved to effect the knitting of tubular
work.
Upon the chains being moved fully in, as before explained, the arms of the pawls a
in engagement with the teeth or notches of the rack bars will be brought into contact
with lugs similar to lug 83 on the opposite side of rack bars, with the effect of
reversing the position of the pawls, or in other words, moving the pawls to their first
mentioned position.
The means whereby pin m is automatically raised will next be explained.
On shaft H is a pinion a" meshing with and operating a gear 6 supported on a
stud connected with a bracket f" attached to the frame of the machine, which gear 611
is provided on one side with a cam e¹ and on the other side with a cam d¹¹.
ell designates a lever pivoted to the lever f", which lever is provided on its free end
with a bowl g arranged to rest upon the cam cl, and it may be held there against by
a spring (not shown). To the free end of lever el is pivoted a pawl h" which rests
upon the ratchet wheels ¹¹, j", the former of which is fast on the arbor k¹¹ while the
latter turns loosely thereon. To one side of the ratchet wheel is secured a sprocket
wheel carrying an endless chain m¹¹ provided with a laterally projecting pin n¹.
Secured to arbor and along side of sprocket wheel 1 is a disc o" provided on its
periphery with a radially projecting pin p", which pin p" is adapted in the revolution
of chain m¹¹ to be engaged by the laterally projecting pin n₁ on the chain and so
carry said disc and ratchet wheel " around therewith.
11
Secured to the opposite end of arbor k¹¹ is a disc q¹¹ Fig. 6 having a notch or
depression in its periphery and upon this disc rests the free end of a lever sll
provided with a toe or projection t¹ at the point where it lies on the disc q. u is
a rod or strip connecting pin m with lever s". It will now be understood that when
the toe of the lever rests in the notch or depression of disk q¹¹, pin m
will be drawn down, but when the disc q is revolved so as to bring the toe (11
on the highest part of the periphery of said disc the pin m will be raised; and
to properly time the operation of disc q" is the purpose of the mechanism just
previously described.
Ratchet wheel having one tooth cut away as shown at 11, Fig. 8, will not
be operated by the pawl when it reaches said mutilated tooth, and consequently
arbor will not be moved. Ratchet wheel j¹¹, to which is attached sprocket
wheel will, however, be moved around an arbor k", and eventually bring the
pin n", of chain m¹ into contact with pin pl of disc o" and so move arbor All
and ratchet wheel that pawl h" will catch into the whole teeth of same and so
move said ratchet wheel i, arbor and disc o¹¹.

page_text: It is of course, understood that instead of providing means of raising pin m, said
pin might be raised and lowered by hand, and, indeed, all of the pins connected with
or operated by the ratchet ring k, may be placed in operative position, removed or
adjusted by hand.
In Figs. 3, 9 a designates a disc secured to arbor ", which disc is provided
on its periphery with cams &c. d designates the angular lever fulcrum on a
stationary part of the machine, and extending around the gear 6 and outward
toward or over the disc alli
A slide eis arranged beneath a lever d¹¹ so as to have a limited movement
thereunder, slots f being for this purpose formed in said lever, and the shanks of
headed screws gill pass through said slots and screwed into the slide. 1 designates
a lever, fulcrumed at to the side of the slide, and provided at its forward end with
a laterally projecting pin which rests upon the periphery of the disc a. The
end of lever is notched to adapt it to engage a pin k on the end of lever dill,
and hold the slide el out against the stress of a spring 11, one end of which is
connected with the lever and the other with the slide.
of
When the arbor 1 is revolvéd, the disc a¹ will be operated in like manner,
until one of the cams or c is brought into contact with the pin
lever, when said lever will be moved on its fulcrum so as to disengage its
notched end from pin of lever 1, allowing the spring to move the slide e¹¹¹
inward to a position where it will be struck by cam di in the rotation of the
gear 61, moving the lever to one side, as from the full to the dotted line
position (Fig. 9), by which operation the pin ml in said lever acting upon the
inclined sides of the forked end of arm or finger T, will move said arm to the
position in which it is represented in said last-mentioned Figure, the result of
which will be to operate arbor P so as to cause arm S to move clutch collar K
to a position intermediate of the pulleys I I and disengaging it from both, thus
stopping the machine.
This stopping of the machine is desirable at times, as when the knitting of a heel
or toe is to be commenced, and when such work is completed, the cam
for the first-mentioned purpose and cam c¹ for the latter.
being
In order to relieve the parts of the machine of undue strain, avoid unnecessary
noise and accomplish other desired ends, I have devised a friction clutch mechanism,
(shown best in Figs. 19 to 22 inclusive) which I may employ in place of the positive
clutch device hereinbefore described. In said last-mentioned Figures is shown a
pulley I loosely arranged on shaft H. Said pulley is provided on one side with
an annular groove h³, in which is placed a ring, split or divided transversely as
at to admit the flat part on the end of a stud 15, the shank of which is made
round and is passed through a hole formed through a disc m³ near the periphery
thereof.
The ring is so constructed as to fit the groove of the pulley, but not so as,
when in its normal position to be bound thereto, and disc m' is made fast on shaft o*.
The stud stands beyond the face of disc m³, and to it is fastened the lever n' by a
set screw or other suitable means. The lever n is provided on its free end with a
laterally projecting finger 05, as shown.
Both pulleys are organized and equipped as has just been described, such equipments
being on adjacent sides of said pulleys.
With this device the ends of collar K are bevelled as shown, and said collar is so
arranged that it moves toward either the pulley I the bevelled end of the collar
adjacent to the pulley towards which it is moved will pass under the projecting
finger o of lever no, moving the free end of said lever outward and turning stud to and
its flat part k extending between the ends of the split ring so as to expand said ring
and cause it to bind in the groove h of the pulley and cause the latter to turn with
the disc m fast on shaft H. When the collar K is moved away from the pulley with
which it has been engaged toward the other pulley, said pulley will pass from under
the finger of belonging to the equipments of the former pulley, so as to allow the split
ring of said pulley to contract, and the latter to run loose on shaft H.

page_text: Another feature of my invention consists of means for automatically changing the
speed at which the machine is driven without stoppages, which improved means may
be employed in lieu of the stop-motion mechanism herein before described.
The stop-motion mechanism being removed a disc u is secured to the end of
arbor k, which disc has an intermittent movement, in predetermined time, imparted
to it from shaft H, through the medium of gearing and other devices which actuate
pawl, arranged to operate on ratchet wheel 1, which moves the pattern chain, and
actuates the arbor k, all as hereinbefore described. The disc u is provided at a
proper point on its periphery with a cam of such form as to adapt it to move in ward
toward the axis of disc us, the pin a projecting laterally from the lever, fulcrumed
at e with a bracket de, the pin as being arranged to travel on the periphery of disc u
when not engaged by the cam³.
The lower end of lever de is loosely connected with the inner end of the lever e
secured at its opposite end to a stud ƒ, suitably journalled in a bracket or base 98.
A lever similar to lever q is connected at one end to the stud /6, its opposite free
end engaging a groove in a collar 6. splined on arbor 7, on which arbor is loosely
arranged the pulleys and 16. Collar is constructed and adapted to operate the
same as the collar on shaft H; and the pulleys and are constructed and
equipped in a manner similar to pulleys I.
On arbor j, which may be the same as that upon which the pulleys 0 0 before
mentioned are secured, are secured two pulleys me n³, the former being connected by
a cross belt with pulley I and the latter being connected by a straight belt with the
other pulley I.
o designates a power shaft arranged at any suitable point, upon which shaft is
secured two pulleys p and q, the former being connected by a belt with pulley ko,
and the latter similarly connected with pulley 1°. Pulley 9 is of considerably
greater diameter than pulley p, so that, as a consequence, pulley will be driven at
slower speed than pulley 1.
As it is well known to those skilled in the art, it is desirable in the operation of
knitting machines, to run the machine at a slower rate of speed when the cam plate or
similar device is being reciprocated, as when heel and toe work is being knit, than
when the cam plate is being rotated, as when plain circular work is being produced,
and it is to reach this end automatically as before mentioned, that my improvements
now being described have been provided.
When in the rotation of disc us the cam 2 reaches the pin a on the upper end of
lever be, said end of said lever will be moved inward toward the axis of the disc, and
through the medium of levers e and 6, move collar on arbor je so as to connect
pulley with said arbor, and cause the machine to be driven from large pulley qº, at
the higher rate of speed, but when pin a passes cam and rides upon the periphery
of disc u, collar will be shifted on arbor j and the machine will be driven from the
pulley at the slower rate of speed, it being understood that the arbor is rotated by
the pulleys and respectively from the pulleys p and q, as said pulleys ke
and may become connected with the arbor through the medium of clutch
collar.
When pin a becomes engaged by the cam the rotation of disc u³ will cease for
the time being, and the pin R in the cam plate will be depressed or removed so as
not to engage the inner end of lever Q, but when the pin a leaves the cam³,
the machine will be operated at the slower rate of speed, as has been explained, the
pin R will be raised, and the collar K intermittently shifted on shaft H so as to
connect or clutch said shaft first with one and then with the other of the pulleys I
which, being rotated in opposite directions, will effect a reciprocating movement of the
cam plate as will be understood without further description."
It is to be noted that changes may be made in the form and arrangement of parts
comprising my improvements without departing from the nature or spirit of my
invention.
