Improvements in Knitting Machinery.
A communication from abroad by GEORGE DUNNING MAYO, of Franklin, in the
County of Merrimack, State of New Hampshire, United States of America,
Manufacturer.
I ALFRED GEORGE BROOKES, of 55 & 56 Chancery Lane, in the County of London,
Chartered Patent Agent do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to improve that class of knitting machines wherein
a cam cylinder has both a rotary and a reciprocal motion, the changes from one to
the other motion, to enable the circular part of a stocking, and then the heel or toe
part of a stocking to be knitted, being made or effected entirely automatically.
The improved machine has two thread carriers, preferably made as rings, each
having its own independent thread, one to feed the needles when circular work is being
done, and the other to feed the needles when reciprocal knitting is being done, as for
heel and too work, thus making it possible to put a thread of a different size or color
from that of the leg into the heel and toe, the said thread carriers being sustained on
a support preferably independent of the cam cylinder, said support being so made
that it may be raised and turned aside from above the top of the needles in the needle
cylinder when it is desired to put a rib top onto a stocking to be knit.
When circular work is heing done, the thread carrier having the heel and toe
thread remains stationary.
The thread carrier having the thread for circular work is in this instance preferably
located above the thread carrier having the heel and toe thread.
When circular work is being done, the thread carrier carrying the thread for that
work is rotated continuously with the cam cylinder, by devices located outside the
cam cylinder, said devices being preferably actuated by gear teeth attached to the
bottom of the cam cylinder, but the said devices may be actuated from any other
suitable parts of the machine.
When circular knitting is discontinued, the circular movement of the thread carrier
then in use, is stopped, and a latch operatively connected to the thread carrier carrying
the heel and toe thread, is automatically engaged by an actuating device, which may
be a projection which has imparted to it a movement in unison with the cam cylinder,
which latter during heel and toe knitting has a reciprocal motion.
The machine has a clamp to automatically catch and hold the heel and toe thread
whenever it is to be thrown out of action, thus preventing the accumulation of any
slack thread which might get to the needles, the said clamp effecting the purpose of a
tension device when the thread is being used.
Suitable means whereby the changes from circular to reciprocal knitting may be
effected in a simple and positive manner.
A pattern surface effects the changes in the direction of motion of the cam cylinder,
and the length of stitch not only in the leg to gradually tighten the stitches, but also
to make one or more slack courses useful to the operator in picking the open end of
the toe onto a seaming machine, and also if desired, to make at a short distance there-
from one or more other slack courses to aid in separating the stockings knitted, one
connected to another, and the pattern surface may also stop the machine at the

page_text: completion of a stocking, and control the time of movement of each of two thread
carriers.
The pattern surface referred to is actuated by pattern gears, which may be on the
shaft of the pattern surface, said gears having means for actuating them at a fast or
slow speed to thus provide for effecting quickly any desired alteration in the length of
the stocking with the same gears and pattern surface.

A needle cylinder, its lifting ring, a pattern surface having a cam, means to move
said pattern surface and intermediate mechanism moved thereby to elevate said needle
cylinder twice in succession immediately after completing the toe to make two
independent slack courses separated by usual knitting.
A ratchet wheel, its actuating pawl, and the clutch-operating lever, mechanism
intermediate said lever and said pawl, and means to actuate said lever preparatory to
reciprocal knitting whereby said pawl may be disengaged from said ratchet during
reciprocal knitting.
The machine has a table or bed suitably supported.
The main shaft provided with pulleys, belt driven from any suitable source, shipper
fork, slide, a guide running against a stud, a block sliding on a stud, and being acted
upon by a spring to keep the belt upon the outer one of the loose pulleys, the belt
being shifted from one to the other of said loose pulleys by means of a link, connected
to the block and to an arm, of a rock shaft mounted in bearings at the side of the
machine, and having a handle.
When this handle has been turned far enough to put the belt on the fast pulley the
arm rests on or just above one arm of a pivoted elbow lever.
The link has an adjusting device which may be adjusted so as to strike the arm
sooner or later after the pivot connecting the link and arm passes the line of centre of
the shaft to thus determine the ease of motion of the link.
The cam shaft has fast on it a toothed gear which engages a toothed gear the
said gear engaging the beveled toothed ring attached to the lower end of the cam
cylinder.
The main shaft has upon its hub part of a clutch, said hub being grooved externally
to receive a two-part ring each half having a suitable stud which enters a hole in one
of the forks of a pivoted clutch arm, jointed by a link to a pin, located at the inner end
of a pivoted clutch lever, and provided with pattern controlled pins or projections.
The hub, has at its sides, spring pins normally projecting through plates or washers,
fast to the sides of the hub.
The shaft is surrounded by a bushing, in turn surrounded by a collar, the collar
and bushing being fastened to the shaft by a screw, the end of the bushing being
surrounded by a loose gear having a hole to receive the pin, the longitudinal movement
of the gear on the hub being prevented by a flange at one end of the hub.
The said shaft has loose upon it a pinion which is secured to a sleeve of the loose
pulley said pinion engaging and driving whenever the machine is in motion a large
toothed gear, said pinion having a hole in its face to receive the pin.
The gear has a crank pin provided with a link, attached to a stud on a toothed
pivoted segment, said segment engaging the loose gear, and oscillating it con-
tinuously.
When the pin of the clutch hub engages the gear, the main shaft will be rotated
for circular knitting, and the segment will move the loose gear back and forth on its
hub, but when the hub is shifted, so that the pin of the clutch engages the gear, the
latter becomes fastened to the main shaft, and the segment actuating said gear will
oscillate the said shaft for reciprocal knitting for heel and toe work.
The main shaft has a pinion which engages a toothed wheel, mounted on a stud,
said toothed wheel having connected to it by suitable screws a slotted plate in which
is adjustably mounted a crank pin, baving attached to it a link, in turn connected to
the lower end of a pawl carrier, pivoted on a stud, said pawl carrier having an arm
on which is mounted a spring actuated pawl, which normally engages the teeth of a

page_text: ratchet wheel, which is the prime mover of the pattern gears and pattern surface or
mechanism to be described.
The crank pin may be adjusted to control the stroke of the pawl, so that it will
move the said ratchet wheel the distance of one or any desired number of teeth, the
greater the movement of said ratchet wheel the shorter the stocking, and rice rersa,
the ability to control the movement of the said ratchet wheel enabling it to be used
for any length of stocking.
The pawl has, a pin which, when the knitting is to be changed from circular to heel
and toe knitting, during which time the pattern wheels, are to be left at rest, is
struck by one end of a lever, connected by a link, with an elbow lever pivoted on the
frame-work, said elbow lever having attached to it a pivoted link projecting from the
clutch lever which latter is moved when the change from circular to reciprocal
knitting is to be made, and vice versa, by the pattern surface.
The outer end of the clutch lever, is bifurcated to embrace the wheel, the
bifurcated part being provided with sliding pins, each sliding pin being provided near
one end with a projecting cross pin, the cross pins entering each its own inclined or
cam slot, in a sliding bar, which is moved in one or the other direction, to change
from circular to reciprocal knitting, and vice versa.
The bar has jointed to it a pivoted lever, having connected to it a link slottel at one
end, to embrace and slide on a screw stud, carried by a change lever, having three
arms, and pivoted on a stand, attached to the bed.
.The shaft and the parts surrounding it at the right of the frame constitutes the
pattern surface.
The change lever is acted upon at its right hand end when the change fro:n circular
to reciprocal knitting is to be made, by a.latch, forming part of the pattern surface,
said bar being carried by a radius bar, mounted loosely on the hub of a disc, fast on
the shaft, having as its bearing a short sleeve, said radius bar having an attached
clamping dog, which bears against the periphery of the said disc, so that said bar
rotates with said disc, and at the proper time strikes said lever.
A spring acts on the latch to hold it normally away from the bar.
The left-hand end of the change lever is acted upon when the change from
reciprocal knitting to circular knitting is to be made, by a pivoted latch, the hub of
said arm surrounding the hub of a disc, loose on the sleeve, which is secured to the
stand the said arm being made adjustable, a spring acting on said latch.
The needles will be held in grooves in a needle bed, surrounded near its upper end
by a ring having radial cross grooves for the reception of a series of jacks or
sinkers, actuated by cams of a suitable sinker ring, having actuating ears such as
designated in the Specification of Letters Patent No. 17388 dated the 13th day of
October 1891 granted to the said George Dunning Mayo.
The cam cylinder may be and as now used is substantially the same as the
cylinder designated in and shewn in Figs. 19 and 20 of drawings accompanying
the said Specification of Letters Patent No. 17388 of 1891, it being provided at its
inner side with cams or devices as provided for in said patent specification for
actuating the needles for circular and reciprocal knitting, a gate for putting out of
action the needles not to be used in knitting the heel or toe, and needle elevators to
engage the heels of and put up out of action at each narrowing course needles at the ends
of the series of needles used in narrowing for the heel and toe, and needle depressors
to engage and pull down the needles at each widening course, and latches to
co-operate with said elevators and depressors.
The switch for pulling up the needles not to be used for reciprocal knitting and for
putting them down when again to be used, has, its stem passed through a plate
attached to the outer side of the cam cylinder, and said steni outside said plate has
feather-splined on it a gear, which is kept on the stem by a screw, said gear being
engaged by the teeth of rack, which may be connected to a slide, fitted into a guide-
way, of the said plate, said rack when raised or lowered, turning said switch, the rack
being raised to move the switch to put up those needles which are not to be used for.

page_text: heel or toe knitting, said rack being lowered to put the switch in position after a heel
or toe has been finished, to pull down all the needles previously lifted, and then to be
used in circular knitting.
The rack has a suitable cam face at one side, with which co-operates a locking device,
as a spring pin holding the rack in position.
This rack has a projecting pin, which, preparatory to narrowing, is struck by the
lower one of a pair of switch shifters, one shifter resting above the other, and each
being acted upon by a suitable spring.
The lowermost switch shifter has a space, into which enters a projection, carried by
the shifter ring, said ring having given to it a slight movement, just as the change
from circular to reciprocal knitting is to be effected, the arrival of the said projection
-opposite said notch letting one of the springs move the cam-shaped end of said shifter
into the path of movement of said pin, and at the same time said projection acts
against and moves the uppermost shifter in the opposite direction.
After the heel or toe has been completed, the ring is moved in the opposite
direction, causing the said projection to act on and move outwardly the shifter, and
let the shifter come into action to strike the upper side of said pin and move the rack
and switch to put all the needles again into position for circular knitting.
The elevator latches referred to have projecting pins, and the depressor latches have
projecting pins, which at times are struck by cam posts which are permitted to come
into operative position by the change in position of the shifter ring."
For instance, when the endmost needles engaged in heel and toe work are to be
raised at the end of each course in usual manner for narrowing, the can post is put
in operative position to be struck by the pins, of the latches co-operating with the
-elevators, and when the said needles are to be drawn down for widening, the cam is
put in place in order that it may be struck by the pins projecting from the latches
co-operating with the depressors both and all common to said Specification of Letters
Patent No. 17388 of 1891.
The cams used herein are found substantially in said Specification of Letters
Patent No. 17388 of 1891, but herein I employ one cam instead of two, each
containing a double acting face, said cams being pivotally mounted on the bed or table
top of the machine, and acted upon by suitable springs to keep them pressed toward
the actuating cam plates attached to the ring, said ring and cain plates being common
to said Specification of Letters Patent No. 17388 of 1891.
At the right hand side of the disc, and preferably forming part of it, is a cam,
which acts on a rod, and moves it to actuate a thread-cutting mechanism.
A ratchet wheel having a laterally extended peripheral flange, is connected to the
disc by suitable bolts.
The flange of the ratchet wheel has a bevel pointed pin which at the proper times
acts on and lifts a rod causing it to move a holding lever, which engages the left hand
side of a projection fast on the ring, at the right of the cam, and lets the spring act
to draw the ring far enough to cause the cam to release the cam post and let it
come into position to be struck by the pins, of the latches co-operating with the
-elevators.
The ratchet wheel of the pattern surface, derives its movement from a pawl carrying
lever, mounted loosely, on the sleeve, said lever having mounted upon it a spring-
controlled pawl, and a latch, the latter resting normally against a stop pin.
The upper end of the pawl carrying lever is acted upon by a spring, attached to
the frame, and the backward stroke of the pawl is determined by an adjusting stud or
device, also in the frame.
When the gear is moving in the one direction circular knitting being then effected,
the projection, attached to said gear, strikes the latch and turns it about its pivot,
but when said gear is being moved in the opposite direction for reciprocal knitting,
then the said projection meets the right hand side of the latch, and moves the pawl
carrying lever and pawl, causing the ratchet to be fed around during reciprocal
knitting and carry with it the disc and arm, and latch, until said latch meets the change
lever.

page_text: The outer end of the shaft has loose upon it a mutilated toothed pattern wheel'
having adjustably attach d to its inner side a segmental plate having teeth, and also-
having a pin.
Fast on said shaft alongside said wheel is a second pattern wheel having also.
mutilated teeth, and a pin.
The said wheels are both engaged by a wide pinion as described in the said Specification:
of Letters Patent No. 17388 of 1891 wherein said wheels, are fully described, they
being used to move the pattern surface at the proper speel and time to determine the
times at which the motion of the cam cylinder is changed, and consequently determine
the length of the leg and foot of the stocking.
The time that the wheel and the shaft and its connected parts remain idle, control
the length of the stocking being knittel, substantially as provided for in said.
patent.
Both wheels have, smooth peripheral portions, alongside of their toothed portions,
against which act suitable spring-pressed brakes or shoes both alike, they serving to
hold the said gears when not to be positively actuated.
The inner end of the shaft has fast on it a disc, the hub of which is surroundel by
the inner end of an arm, which is extended from the shaft in a direction opposite.
an arm, having an attached clamping dog, carrying a latch actuated by a suitable.
spring, to keep it normally toward a stop, the said arm travelling with the said dise,.
by reason of the friction of the dog against it.
The disc has connected to one side of it by a suitable screw, a plate, having one-
or more groups of ratchet teeth, engaged by a pawl loosely mounted on the hub of
the plate, pivoted on a pawl carrier, said carrier being provided with a roller or other
stad, which is kept in contact with a cam on the wheel, by a spring, said wheel
rotating in unison with the cam cylinder, the said pawl at times engaging the teeth.
referred to.
The disc and plate are both connected to the shaft, and move together.
The disc has fixed to it at its outer side two cam segments, the latter being
adjustably attached to the disc by a screw, the cam being carried by a plate, so that it
may be adjusted in a circnlar direction at the side of the cam.
Just as a stocking is finished, if the machine is to be stopped, an abrupt end of
the cam meets a stud on a pivoted lever, connected to and to move the lever and
through the link turn the arm to effect the transfer of the driving belt.
Herein, as in the said Specification of Letters Patent No. 17388 already referred
to the lower end of the needle cylinder will be provided with notches which will rest
on a ring provided with projections, and said ring has a connected handle which is
pivoted to a block on a rod, the movement of the said rod operating said ring to
raise or lower the needle cylinder to lengthen or shorten the stitches.
When a stocking is to be started, the stitches in the larger part of the leg should
be a little looser or longer than in the lower part of the leg and the foot, and the-
roller or other stud will consequently stand on the lower part of the cam just beyond
the second high part, and in such condition the lever acts against the collar and
compresses somewhat the spring, and as the knitting progresses, the said cam travels.
over said roller and when the leg should begin to be contracted, the roller comes onto
the cam, and as said cam travels over the said roller the lever is gradually moved
away from the collar, letting the spring gradually out until the needle cylinder is down
in the position for the shortest stitches.
At or about as the toe is completed, the first most abrupt end of the cam meets
the roller cr other stud and just at this time the lever is moved, causing the pawl to
engage the ratchet teeth and impart to the plate a quicker movement than would be
effected by the gear wheels, thus giving to the levers, quick movements, causing the
outer end of the lever to act upon said collar and push the rod in opposition to
the spring, and cause said rod to turn the needle cylinder elevating ring, to thus
lift said cylinder quickly to provide for stitches of the greatest length, and as the
roller or other stud passes over the high part, some longer stitches will be made for
a slack course.

page_text: When the abrupt part of the cam was operated as described, to act on and move
the lever, the ratchet teeth had just arrived in position to be engaged by the pawl
and engaging said teeth it gave to the shaft its attached disc, and cam part a quick
movement, or a movement faster than that at which it previously moved, to thus
cause said abrupt part and part to act quickly and form but one or more slack courses
before stopping the machine.
The machine having been stopped and the stocking run off, it may be again started,
and if the stocking is to be short and knitted to a rib top, then hut one abrupt part
and high part will be neo-led, but in case it is desired to knit stockings connected
tgether, we remove the link, and apply to the cam two abrupt parts and high parts,
and a second set or pair of teeth, so that after one or more regular courses have
been knitted, we may again raise the needle cylinder to make a second slack
course by means of which to accurately separate or sever the leg of one stocking
from the toe of a previously knitted stocking, and then the knitting will continue
until the stocking is ended, when the action described will be repeated."
The plate has attached to it by a serew, a block, to which is secured in an
adjustable manner a brake or friction strap, which surrounds the sleeve, thus
preventing undue movement of the said plate, and its attached parts on the
shaft.
The inner end of the lever is joined by the link to the clutch arm, and as the lever
is moved, it moves the clutch arm in one or the other direction, and the extreme
outer end of said lever in its lateral movement strikes and passes the pointed end of
a spring-pressed pin, thus holding the lever in the position in which it may be left by
the cam lugs.
The forked end of the clutch lever, has a stud, which is engaged by a lever, free
to turu on a pivot, said lever being extended through a slot in the bed, and having
connected to its upper end a link, and a second link, which is joined to a lever, of
elbow shape, said lever being connected by a link to and so as to become the mover
of the trip, which by acting against the lug on the ring moves the latter in a direction
opposite when circular knitting is to be commenced, said trip standing in the position
during circular knitting, but being moved positively in a direction to release said lug
and let the spring assume control of and to move it preparatory to commencing
reciprocal knitting.
The ring has in addition to the cam plates and block, another cam plate.
This cam, when the ring is moved to enable reciprocal knitting to be done,
releases the cam post and permits it to put into operation the actuating means for
moving the thread carrier used for reciprocal knitting.
The slide and latch constitute what is designated as the actuating device for the
thread carrier.
The thread carrier support also serves to sustain a thread carrier or ring, which
carries the thread used in circular knitting, said carrier resting in said case, just
above the carrier.
The out-turned flange of the carrier or ring is toothed, and said teeth are
engaged by the teeth of a gear, loose on the hub of a circular or cam plate,
splined on the said shaft, sustained in the frame, said can plate rotating with said
shaft and being free to slide thereon as required.
The plate has its upper side made in the shape of the can, the said cam having
screwed to its lower end a friction plate.
The shaft has at its lower end a gear, which engages and is rotated by the
teeth of the gear fast on the lower end of the cam cylinder.
The gear has extended upwardly from its top side a nearly circular wall, slotted,
one of said slots having pivoted in it, one end of a disengaging latch, the opposite
downturned end of which enters the opposite notch, the said opposite end having
also a projection, which at times may be acted upon by cams attached to a gate
of a stationary cam box or cover surrounding the said gear and cam plate, and
loose on the shaft.
During circular knitting the shaft is rotated continuously, and the gear in

page_text: operative engagement with the teeth of the tire ul carrier or ring, rotates the same;
and during circular knitting, the gate is open, it being held open by a pivoted lever
the upper end of said lever, entering a staple attached to the said gate, the inner
lower end of said lever, much the heaviest, resting on the face of a disc provided with
a notch, a spring acting on said lever to keep it down on said disc.
The heavier end of said lever enters the notch of the disc just about as reciprocal
knitting is to be commenced, and as the lever moves, it closes the said gate, and
brings the cams attached thereto, in such position that the cam acts on the end of
the latch, and partially lifts the same, and at the same time the clutch is shifted
to effect the oscillation of the main shaft for reciprocal knitting and consequently
the cam cylinder after having moved the shaft in one direction reverses said shaft,
and in its reverse movement the cam of the gate catches under the partially raised
end of the disengaging latch and lifts it fully from engagement with the cain, thus
freeing the gear from the control of the said cam, and enabling the said cam to
reciprocate with the shaft, without rotating the said gear and the thread carrier or ring.
As the cam acts on the disengaging latch, the cam plate acts to release the lever,
so that its upper end comes in range of and is struck by the pin of the slide, thus
lifting it into position to he engaged and held by the latch acted upon by a spring,
said latch being pivoted upon a projection, connected to the thread carrier or ring,
carrying the heel and toe thread, and as soon as the cam cylinder and the said ring
are coupled together as described, the said thread carrier or ring is is reciprocated
with the said cam cylinder.
The link before described has its inner end connected to an arm, fast on the
vertical rock shaft, said shaft baving a second arm, to which is joined a link, in turn
shown as connected by two elbow levers, a link and a short rod, with a cam, which
actuates a clamp lever, through a spring, said clamp lever being pivoted and being
cut away to embrace the enlarged end of a short stud to which is fixed an elbow
lever, and having its hearing in a part of the frame, one arm of said lever having
adjustably attached to it a take up device, acted upon by a suitable spring, attached
at its free end to a rod projecting from the other or toe arm of said lever, the latter
arm being so located as to act on a pin, having attached to its lower end one miember
of a thread clamp or tension device, the upper member thereof being fixed to a short
tubular guide, attached to the stationary frame arm.
The pin has a suitable pin, which rests on a spiral spring in said tube, the spring
normally acting to keep the clamp closed on the thread used to knit the heel and toe,
but in case of excessive strain on the said thread, the take-up lever as it is drawn
down causes the toe to act on and depress the pin, and open the clamp to permit the
thread to pass freely.
The rock-shaft has a cam, which operates a lever, said lever being pivoted and
having its opposite end pin-jointed to an L shaped slide, said slide having at its
underside near its outer end a hevelled or inclined part, the said slide preparatory to
commencing circular knitting being moved to put its inclined portion in line with
the upper side of the pin, to thus depress the slide and disconnect the thread carrier
or ring, leaving it at rest, and while at rest said ring must be held or restrained from
movement.
This is effected by a stop, said stop being pivoted and having a pin which is acted
upon by a lug carried by said slide.
The stop is held in one or the other of its two positions by a spring-pressed pin,
engaging the pointed or notched end of said stop.
When the ring is again to be moved for reciprocal knitting, the slide is retracted
and its lug retires from the pin, and at substantially the same time the slide is raised
to engage the latch and start the said ring and as it starts, the bevelled portion, acting
against the bevelled portion of the stop, depresses said stop, turning it on its pivot..
When the change is to be made from the reciprocal to circular knitting, at which
time the take up is not needed, the cam is turned in a direction to cause its part of
greatest throw to act on the spring and cause the lever to clamp the stud and hold the
take-up stationary and inactive wherever left.

Dated the 14th day of Iul. 1906
A communication from GEORGE DUNNING MAYO, of Franklin, County of Merrimack,
State of New Hampshire, United States of America, Manufacturer.
I ALFRED GEORGE BROOKES of 55 & 56 Chancery Lane, in the County of London
Chartered Patent Agent, 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 :-
This invention has for its object to improve that class of knitting machines wherein
a cam cylinder has both a rotary and a reciprocal motion, the changes from one to
the other motion, to enable the circular part of a stocking, and then the heel or toe
part of a stocking to be knitted, being made or effected entirely automatically.
The machine herein to be described has two thread carriers, preferably made
as rings, each having its own independent thread, one to feed the needles
when circular work is. being done, and the other to feed the needles when
reciprocal knitting is being done, as for heel and toe work, thus making it possible
to put a thread of a different size or color from that of the leg into the heel and
toe, the said thread carriers being sustained on a support shown as independent
of the cam cylinder, said support being so made that it may be raised and turned
aside from above the top of the needles in the needle cylinder when it is desired to
put a rib top onto a stocking to be knit.
When circular work is being done, the thread carrier having the heel and toe
thread remains stationary.
The thread carrier having the thread for circular work is in this instance shown as
located above the thread carrier having the heel and toe thread.
When circular work is being done, the thread carrier carrying the thread for that
work is rotated continuously with the cam cylinder, by devices located outside the
cam cylinder, said devices being preferably actuated by gear teeth attached to the
bottom of the cam cylinder,. but the said devices may be actuated from any other
suitable parts of the machine.
When circular knitting is discontinued, the circular movement of the thread carrier
then in use, is stopped, and a latch operatively connected to the thread carrier
carrying the heel and toe thread, is automatically engaged by an actuating device,
shown as a projection, which has imparted to it a movement in unison with the cam
cylinder, which latter during heel and toe knitting has a reciprocal motion.
The machine has a clamp to automatically catch and hold the heel and toe thread
whenever it is to be thrown out of action, thus preventing the accumulation of any
slack thread which might get to the needles, the said clamp effecting the purpose
of a tension device when the thread is being used:

page_text: Particular means are devised whereby the changes from circular to reciprocal
knitting may be effected in a simple and positive manner.,
There is also provided a novel pattern surface to effect the changes in the direction
of motion of the cam cylinder, and the length of stitch not only in the leg to
gradually tighten the stitches but also to make one or more slack courses useful to the
operator in picking the open end of the toe onto a seaming machine, and also if
desired, to make at a short distance therefrom one or more other slack courses to aid
in separating the stockings knitted, one connected to another, and the pattern surface
may also stop the machine at the completion of a stocking, and control the time of
movement of each of two thread carriers.
The pattern surface referred to is actuated by pattern gears, shown as on the
shaft of the pattern surface, said gears having means for actuating them at a fast or
slow speed to thus provide for effecting quickly any desired alteration in the length
of the stocking with the same gears and pattern surface.

In the drawing A represents a table or bed supported upon suitable legs A' which
in practice rest upon the floor, the legs, in this instance being broken off; the legs
and table forming supports for the various devices to be described.
The main shaft A is provided with two loose pulleys A³, A', over which is

page_text: extended a belt driven from any suitable source, the said belt being under the control!.
of a shipper fork A³, connected to a slide block A having a guide A* running against:
a stud Ax, said block A sliding on a stud A7, see Figs. 4 and 5, and being acted upon.
by a spring As to keep the belt upon the outer one of the two loose pulleys, the belt:
being shifted from one to the other of said loose pulleys by means of a link Aº,
connected to the block and to an arm A, of a rock shaft A2, mounted in bearings at
the side of the machine, and having a handle A13 which may be moved by hand when
the machine is to be started.
When the handle A13 has been turned in the direction of the arrow, Fig. 5, far
enough to put the helt on the pulley A3, the arm A10 rests on or just above one arm
of an elbow lever B pivoted on a stud B.
The link A has an adjusting device B60 which may be adjusted so as to strike the
arm A sooner or later after the pivot connecting, the link and arm passes the line of
centre of the shaft A to thus determine the ease of motion of the link..
The cam shaft has fast on it a toothed gear B, shown in Figs. 4 and 5, and by
dotted lines in Fig. 2, which engages a toothed gear B2, shown partially in Fig. 1,
and by dotted lines in Fig. 2, the said gear engaging in usual manner the beveled
toothed ring T, commonly found attached to the lower end of the usual can..
cylinder.
The main shaft A2 has splined upon its hub part of a clutch B3, best shown in:
Figs. 4 and 5, said hub being grooved externally to receive a two-part ring C*, one
half of said ring being shown in Fig. 5, each half having a suitable stud as C, see
Fig. 4, which enters a hole in one of the forks of a clutch arm B³, pivoted at B'x, said:
clutch arm being jointed by a link B2, to a pin 2, located at the inner end of a.
clutch lever D3, pivoted at D, and provided with pattern controlled pins. or
projections axalox"
The hub B, has at its sides, pins a, b, each backed up by a suitable spring,..
so that the said pins normally project through plates or washers a', 6', fast to the
sides of the hub:
The shaft A2 is surrounded by a bushing C, in turn surrounded by a
collar C, the collar and bushing being fastened to the shaft by a screw C, the
end of the bushing being surrounded by a loose gear C having a hole to
receive the pin a, the longitudinal movement of the gear on the hub being
prevented by a flange at one end of the hub.
The said shaft A has also loose upon it at the opposite side of the said hub B¹³,
see the left-hand side thereof in Fig. 5, a pinion which is secured to a sleeve
of the loose pulley A3; said pinion engaging and driving, whenever the machine
is in motion, the large toothed gear 0, to be described, said pinion having a hole
in its face to receive the pin b.
The gear has a crank pin provided with a link Co which at its opposite
end, see Fig. 6, is attached to a stud on a toothed segment C¹³, pivoted at C¹³,.
said segment engaging the loose gear C, and oscillating it continuously.
When the pin of the clutch hub B13 engages the gear C, the main shaft.
will be rotated for circular knitting, and the segment will move the loose gear (.
back and forth on its hub, but when the hub is shifted, so that the pin a of the
clutch engages the gear C, the latter becomes fastened to the main shaft, and:
the segment actuating said gear will oscillate the said shaft for reciprocal knitting:
for heel and toe work.
The main shaft A2 has fast on it at one end, see Fig. 2, a pinion D* which
engages a toothed wheel D', mounted on a stud D2, shown by dotted lines Fig. 2,.
said toothed wheel having connected to it by suitable screws a* a slotted plate a
in which is adjustably mounted a crank pin D3, having attached to it a link. D,
a stud a
in turn connected to the lower end of a pawl carrier D, pivoted on
said pawl carrier having an arm a³ on which is mounted a spring actuated pawl as,
which normally engages the teeth of a ratchet wheel D, which is the prime mover.
of the pattern gears and pattern surface or mechanism to be described.
The crank pin D³ may be adjusted to control the stroke of the pawl a³, so that.

page_text: it will move the said ratchet wheel the distance of one or any desired number of
teeth; the greater the movement of said ratchet wheel the shorter the stocking,
and rice rers, the ability to control the movement of the said ratchet wheel
enabling it to be used for any length of stocking.
The pawl a has, see Figs. 2 and 4, a pin a which, when the knitting is to
be changed from circular to heel and toe knitting, during which time the pattern
wheels a, a, are to be left at rest, is struck by one end of a lever D, con-
nected by a link D³, with an elbow lever D' pivoted on the frame-work, said
elbow lever having attached to it a link Do, pivoted at D, to a lug 4, projecting
from the clutch lever D¹³, which latter is moved when the change from circular
to reciprocal knitting is to be made, and vice versa, by the pattern surface.
The outer end of the clutch lever D13 is shown as bifurcated to embrace the
wheel C, see Figs. 2, 4, 6 and 7, the bifurcated part being provided with the
sliding pins a, a, referred to, each sliding pin being provided near one end
with a projecting cross pin, the cross pins entering each its own inclined or cam
slot a, a, in a sliding bar a¹³, which is moved in one or the other direction,
according as it is desired to change from circular to reciprocal knitting, and
vice versa..
The bar a has jointed to it a lever ax, having its fulcrum on the pivot D¹³,
said lever a having connected to it a link a slotted at one end, see Fig. 4, to
embrace and slide on a screw stud a, carried by a change lever a", it having,
as shown, three arms, and being pivoted at a¹8 on a stand a18x, attached to
the bed..
The shaft E and the parts surrounding it at the right of the frame A¹, see
Fig. 3, constitutes the pattern surface.
The change lever at is acted upon at its right hand end when the change from
circular to reciprocal knitting is to be made, by a latch 3, forming part of the
pattern surface, see Figs. 4 and 9, said latch being carried by a radius bar x,
mounted loosely on the hub x of a disc 650, fast on the shaft E, having as its
bearing a short sleeve c³, said radius bar having an attached clamping dog b, the
acting edge of which is concaved to bear against the convexed periphery of the
said disc, frictionally with sufficient force to cause said bar to rotate with said
disc, and at the proper time strike said lever a¹.
A spring 60 acts on the latch 3 to hold it normally away from the bar b¹x.
The left-hand end of the change lever a" is acted upon when the change from
reciprocal knitting to circular knitting is to be made, by, see Fig. 11, a latch e*,
pivoted on a radius har c', shown by dotted lines in Fig. 11, and in full lines
Fig. 4, and in section Fig. 3, the hub of said arm surrounding the hub of
a disc c, loose on the sleeve c³, which is secured to the stand A, the said arm c¹
being made adjustable about the said hub by a set screw c, in a slot of said
arm, see Fig. 11, a spring e, acting on said latch ex to normally press it away
from the arm c¹.
The needles n will be held in grooves in a needle bed a², surrounded near its
upper end by a ring as having radial cross grooves for the reception of a series
of jacks or sinkers a, actuated by cams of a suitable sinker ring a", having
actuating ears a², such as designated by like letters in the specification of Letters
Patent No. 17388, dated the 13th day of October 1891 granted to the said
George Dunning Mayo.
The cam cylinder B is substantially the same as the cylinder designated by the
letter a in and shewn in Figs. 19 and 20 of drawing accompanying the said
Specification of Letters Patent No. 17388 of 1891, it being provided at its inner side
with cams or devices, substantially such as shewn in said patent specification and in
Figs. 21, 25 and 26, for actuating the needles for circular and reciprocal knitting, and
with a switch for putting out of action the needles not to be used in knitting the heel
or toe, and needle elevators to engage the heels of and put up out of action at each
narrowing course needles at the ends of the series of needles used in narrowing for

page_text: the heel and toe, and needle depressors to engage and pull down the needles at each
widening course, and latches to co-operate with said elevators and depressors.
Inasmuch as the cam cylinder and its cams, elevators and depressors, and their
latches, etc. are all fully shown in said Specification of Letters Patent No. 17388
of 1891, it is considered unnecessary to herein show the same, but I have illustrated
in Fig. 26 the switch and its actuating devices, for they differ from the devices of the
said patent.
The switch D for pulling up the needles not to be used for reciprocal knitting and
for putting them down when again to be used, has, see Fig. 25, its stem passed through
a plate N attached to the outerside of the cam cylinder B, and said stem outside said
plate has feather-splined on it a gear n', which is kept on the stem by a screw n³, said
gear being engaged by the teeth of rack n³, shown as connected to a slide block n',
fitted into a guideway no, of the said plate, said rack when raised or lowered, turning
said switch, the rack being raised to move the switch to put up those needles which
are not to be used for heel or toe knitting, said rack being lowered to put the switch
in position after a heel or toe has been finished, to pull down all the nee:fles previously
lifted, and then to be used in circular knitting.
The rack has a suitable cam face at one side, with which co-operates a locking
device n, shown as a spring pin, said locking device holding the rack in the position
in which it may be left by its actuating device.
This rack has a projecting pin n', see Fig. 25, which, preparatory to narrowing, is
struck by the lower one of a pair of switch shifters n³, nº, see Figs. 16 and 27, said
shifters being shown as levers pivoted at 10, one shifter resting above the other, and
each being acted upon by a suitable spring 2, which acts to normally keep the
acting ends of the shifters pressed toward the cam cylinder.
The lowermost switch shifter 8. has a space 5, into which enters a projection n¹³,
carried by the shifter ring e, said ring having given to it a slight movement in the
direction of the arrow on it, Fig. 16, just as the change from circular to reciprocal
knitting is to be effected, the arrival of the said projection opposite said notch letting
one of the springs n move the cam-shaped end of said shifter n into the path of
movement of said pin n', and at the same time said projection n' acts against ant
moves the upper:nost shifter in the opposite direction.
After the heel or toe has been completed, the ring c" is moved in the opposite
direction, causing the said projection na to act on and move outwardly the shifter 8,
and let the shifter n come into action to strike the upper side of said pin n' and
move the rack and switch D to put all the needles again into position for circular
knitting.
The elevator latches referred to have projecting pins and the depressor latches
herein shown and lettered 6, have projecting pins 4, which at times are struck by cam
posts which are permitted to come into operative position by the change in position of
the shifter ring c, all as in said patent.
For instance, when the endmost needles engaged in heel and to work are to be
raised at the end of each course in usual manner for narrowing, the cam post is
put in operative position to be struck by the said pins, of the latches co-operating with
the elevators, and when the said needles are to be drawn down for widening, the
cam dis is put in place in order that it may be struck by the pins 4, 4, projecting
from the latches co-operating with the depressors Le both and all common to said
Specification of Letters Patent No. 17388 of 1891.
The cams and d¹, are formed substantially in said Specification of Letters
Patent No. 17388 of 1891, but herein I employ one cam instead of two, each
containing a double acting face, said cams being pivotally mounted on the bed or
table top of the machine, and acted upon by suitable springs d* to keep them pressed
toward the actuating cam plates 23, d, attached to the ring c", said ring and cam
plates being common to said Specification of Letters Patent No. 17388 of 1891.
At the right hand side of the dise 2, and herein shown as forming part of it, is a
cam e, which acts on a rod c', see Figs. 4 and 11, and moves it to actuate a thread-
C

page_text: cutting mechanism, not shown, but which may be employed when it is desired to cut
the thread, as in my Specification of Application No. 1042 filed 13th June 1896.
A ratchet wheel having a laterally extended peripheral flange, is connected to the
disc c by suitable bolts ex
The flange of the ratchet wheel c has a bevel pointed pin 10x, see dotted lines
Fig. 10, and full lines, Fig. 4, which immediately after narrowing acts on and lifts a
rod c causing it to move a holding lever ex, which engages the left hand side of a
projection fast on the ring 24, at the right of the cam c, and the spring c* acts
for the second time to draw the ring e24 in the direction of the arrow on it far enough
to cause cam to release the cam post is and let it come into position to be struck
by the pins of the latches co-operating with the elevators.
The ratchet wheel of the pattern surface, see Figs. 3 and 10, derives its
movement from a pawl carrying lever c3, mounted loosely on the sleeve c³, said
lever having mounted upon it a spring-controlled pawi c, and a latch e, the
latter resting normally against a stop pin c.
The upper end of the pawl carrying lever c¹³ is acted upon by a spring 18,
attached to the frame, and the backward stroke of the pawl c is determined by
an adjusting stud or device c, also in the frame.
When the gear B1 is moving in the direction of the arrow on it Fig. 15,
circular knitting being then effected, the projection eo, shown by dotted lines Fig. 15,
attached to said gear, strikes the latches and turns it about its pivot, but when
said gear Bo is being moved in the opposite direction for reciprocal knitting, then
the said projection mcets the right hand side of the latch 1, see Fig. 10, and
moves the pawl carrying lever and pawl, causing the ratchet to be fed around
during reciprocal knitting and carry with it the disc c and arm c¹, and latch e*,
until said latch meets the change lever a¹.
The outer or right hand end of the shaft E has loose on it a toothed pattern
wheel a, see Figs. 2, 3, 4 and 13, some of the teeth being cut away to constitute a
mutilated wheel, said wheel having adjustably attached to its inner side a segmental
plate a, having in this instance three teeth; and having also a pin a
Fast on said shaft alongside said wheel is a second pattern wheel a", see Figs. 3, 1
and 14, it having also mutilated teeth, and a pin a23.
The said wheels are both engaged by a wide pinion as, which moves them as
described in said Specification of Letters Patent No. 17388, of 1891, wherein said
wheels, designated by like letters, are fully shown and described, they being used to
move the pattern surface at the proper speed and time to determine the times at which
the motion of the cam cylinder is changed, and consequently determine the length of
the leg and foot of the stocking.
The time that the wheel a and the shaft E and its connected parts remain idle,
control the length of the leg of the stocking being knitted, substantially as provided
for in said patent.
Both wheels, and a19, have, as herein shown, smooth peripheral portions a1, a20x,
alongside of their toothed portions, against which act suitable spring-pressed brakes
or shees E, both alike, they serving to hold the said gears when not to be positively
actuated. The wheel al remains idle a longer or shorter time, that depending upon
the length of the leg of the stocking to be knitted, and during this time the wheel a
is moved, it continuing to move until the teeth of the segmental plate a meets the
pin 23 on the wheel as and thereafter both wheels move together to turn the shaft E
to make the changes necessary to effect the narrowing and widening operations, as
described.
The heel being finished, the shaft E continues to revolve until the foot and toe have
been completed. The wheel a20 is stopped as soon as its toothless space arrives
opposite the pinion a78, the wheel a thereafter continuing to rotate until its toothless
space comes opposite said pinion.
The inner end of the shaft E has fast on it a disc d, the lub of which is surrounded
by the inner end of an arm d', which is extended from the shaft E in a direction
opposite the arm x, said am having an attached clamping dog a² and carrying a

page_text: latch actuated by a suitable spring d', to keep it normally toward a stop d', the
said arm d travelling with the said disc d, by reason of the friction of the dog
against it.
The dise has connected to one side of it by a suitable screw, see Fig. 3, a plate,
shown also by dotted lines Fig. 9, said plate having one or more groups of ratchet
teeth a, a, which are adapted to be engaged by a pawl e'.
The pawle is loosely mounted on the hub of the plate 60, pivoted on a pawl
carrier e, said carrier being provided with a roller or other stud e, which is kept in
contact with a came on the wheel B10, by a spring e, said wheel rolating in unison
with the cam cylinder, the said pawl at times engaging the teeth a and ax,
referred to.
The disc d and plate 600 are both connected to the shaft E and move together.
The disc d carries at its outerside a cam do, and said disc has attached to it by a
screw da plate d having a cam d, said plate being adjustable on the disc d, so that
the distance apart of the cams d and d may be adjusted.
The acting end of the cam de is quite abrupt, as shown at dx, Figs. 3 and 4, and at
the rear of said abrupt end is a high part 12, and at a short distance from said high
part is a second like abrupt incline and high part to be described.
The elbow lever B has connected to it a slotted link B, in which is placed one end
of the tension lever B', see Fig. 7, pivoted at BT, said lever being moved as described
by the high part 12 at the completion of each stocking to turn the arm B' and cause
it to act on A and turn it far enough to let the spring A" act to put the belt on the
outermost loose pulley and stop the machine.
Just as a stocking is finished, if the machine is to be stopped, the first abrupt end
of the cam meets a roller or other stud 8x on a pivoted lever 7, connected by
link 2*, see Fig. 7, to and to move the lever B7 and through the link B turn the
arm B' to effect the transfer of the driving belt onto the outermost loose pulley A,
and the said roller stud stops on the cam d just behind the high part 12 in position to
start the machine.
Herein, as in the said Specification of Letters Patent No. 17388, already referred
to the lower end of the needle cylinder will be provided with notches which will rest
on a ring A provided with projections 4, and said ring has a connected handle 4x,
which is pivoted to a block on a rod B, the movement of suid rod operating said
ring to raise or lower the needle cylinder to lengthen or shorten the stitches.
When a stocking is to be started, the stitches in the larger part of the leg should
be a little looser or longer than in the lower part of the leg and the foot, and the roller
or other stud dx will consequently stand on the lower part of the cam just beyond
the second high part 12, and in such condition the lever B' acts against the
collar B and compresses somewhat the spring B, and as the knitting progresses,
the said cam travels over said roller and when the leg should begin to be contracted,
the roller comes onto the cam do, and as said cam travels over the said roller, the
lever is gradually moved with relation to said collar Bx as to let the spring B¹×
gradually move the rod B and with it the lever 4x, enabling the projection
on the ring to enter the notch in the lower end of the needle cylinder and
let the said cylinder descend into the position for the shortest stitches to be made,
the extent of movement of said rod being limited by the collar 99*.
At or about as the toe is completed, the first most abrupt end of the cam d
meets the roller or other stud d and just at this time the lever e is moved, causing
the pawl e to engage the ratchet teeth a and impart to the plate d a quicker
movement than would be effected by the gear wheels, thus giving to the levers d'
and B' quick movements, causing the outer end of the lever B to act upon said
collar Bk and push the rod B in opposition to the spring B, and cause said 'rod
to turn the needle cylinder elevating ring 4, to thus lift said cylinder quickly to
provide for stitches of the greatest length, and as the roller or other stud passes
over the high part 12, some longer stitches will be made for a slack course.
When the abrupt part of the cam was operated as described, to act on and move
the lever d, the ratchet teeth a had just arrived in position to be engaged by

page_text: the pawl e', and engaging said teeth it gave to the shaft E, its attached disc, and
cam part dx a quick movement, or a movement faster than that at which it
previously moved, to thus cause said abrupt part and part 12 to act quickly and
form but one or more slack courses before stopping the machine.
The slack course just referred to will be useful to the operator who closes the
toe, as it forms a line to indicate where the loops may be put onto the seaming
machine used to close the toe.
The machine having been stopped and the stocking run off, it may be again started,
and if the stocking is to be short and knitted to a rib top, then but one abrupt part d
and high part 12 will be needed, but in case it is desired to knit stockings connected
together, I remove the link B, and apply to the cam a two abrupt parts and high
parts as shown in the drawing, and a second set or pair of teeth, as a³×, see
Fig. 9, so that after one or more regular courses have been knitted, I may again
raise the needle cylinder to make a second slack course by means of which to
accurately separate or sever the leg of one stocking from the toe of a previously
knitted stocking, and then the knitting will continue until the stocking is ended, when
the action described will be repeated.
The plate has attached to it by a screw e', a block e8, to which is secured in
an adjustable manner a brake or friction strap e, which surrounds the sleeve c³,
thus preventing undue movement of the said plate c², and its attached parts on the
shaft E.
The bifurcated end of the clutch lever is shown as embracing the large gear (³,
which has adjustably secured to it on opposite sides cam lugs clox, cx, said lugs
meeting that one of the pins ax or a10x, whichever may be dropped or depressed
by the movement of the cam plate a¹³, thus moving the said lever D13 in one or the
other direction.
The pins carried by the lever D¹³ and which may be changed in their positions
by or through the action of a pattern surface so that by striking the said pins, the
said lever may be moved in one or the other direction as desired to change from
circular to reciprocal knitting and rice versa is an important feature of this invention.
The inner end of the lever D¹³ is joined by the link B to the clutch arm B³,
and as the lever D13 is moved, it moves the clutch arm B3 in one or the other
direction, and the extreme outer end of said lever D³ in its lateral movement strikes
and passes the pointed end of a spring-pressed pin Do, see Fig. 6, thus holding
the lever D13 in the position in which it may be left by the cam lugs.
The forked end of the clutch lever B3 has a stud 3, which is engaged by a lever F,
free to turn on a pivot F', said lever being extended through a slot in the bed A.
The lever F will be turned in one direction when reciprocating knitting is to be done,
and in the opposite direction when reciprocating knitting is to be stopped, the lever F
has connected to its upper end a link F2, and a second link F³, see Fig. 16, which
is joined to a lever F, shown as of elbow shape, said lever being connected by a
link F to and so as to become the mover of the trip F, which by acting against
the lug F7 on the ring C moves the latter in a direction opposite the said arrow
when circular knitting is to be commenced, said trip standing in the position shown
in Fig. 16 during circular knitting, but being moved positively in a direction to
release said lug and let the spring ex assume control of and to move it preparatory
to commencing reciprocal knitting.
The ring has in addition to the cam plates 23 and 2 and block cx, a cam
plate 27.
The cam 27, when the ring 24 is moved in the direction of the arrow on it to
enable reciprocal knitting to be done, releases the cam post and permits it to put into
operation the actuating means for moving the thread carrier used for reciprocal
knitting.
The said actuating means is herein shown as a slide f¹ having a pin 8, and embracing
a guide fx see Fig. 1, the elevation of the slide causing a projection at its upper end
to be put in position to be engaged by a latch f, see Fig. 22, attached to the thread

page_text: carrier for the heel and toe thread, said ring having at its upper end, see Fig. 1,
an outturned flange, which, as herein shown, rests on an inturned flange of a threa
carrier support or case f, having a hub 20, see Fig. 1, provide l with a spline to enter
a hole 21 in a stand p, the hub setting outside of a shaft, the spline being a short-
one, so that it will not prevent the turning of said hub on said shift when the hub is
lifted.
The slide and latch constitute what is designated as the actuating device for the
thread carrier 1',
The case is supported as described in order that it may be lifted and turned aside
from the top of the usual needle-bel when it is desired to use the machine for knitting
half hose wherein a rib top is to be transferred onto the needles preparatory to com
mencing the knitting of the stocking.
To lift the said case, there is provided a hand-operated lever M, pivoted at M', the
short arm M of said lever lying just under the said hub 20, see Fig. 1.
The stand p suitably connectod by screws p", see Fig. 16, to the bad A, supports
the shafts and 4, and also has secured to it, by screws p, the standard p².
The thread carrier support f, also serves to sustain a thread carrier or ring ³,
which carries the thread use: in circular knitting, said carrier being herein
shown as resting in said case, just above the carrier or ring /3, and being retained in
the frame or case by an annular cover 16.
The out-turned flange of the carrier or ring is toothed, see Figs. 1 and 16, and
said teeth are engaged by the teeth of a gear 17, loose on the hub of a circular or
cam plate, splined on the said shaft, see Fig. 1, sustained in the frame p, said
cam plate rotating with said shaft and being free to slide thereon as required.
The plate has its upper side made in the shape of the cam, as best shown in
Figs. 19 and 21, the said cam having screwed to the lower end of its hub a friction
plate 16, see Fig. 1.
The upper end of the plate , see Fig. 21, has a notch 1 in which enters the
disengaging latch 18, which thus serves to couple together the said plate and toothed
ring, so that movement of the plate will move the ring, the inclined parts 10 of the
plate serving to assist in raising the latch 18 after the same has been started
upwardly.
The shaft has at its lower end a gear y which engages and is rotated by the
teeth of the gear T fast on the lower end of the cam cylinder B, see Fig. 1.
The gear has extended upwardly from its top side a nearly circular wall/7
notched at substantially diametrically opposite points, one of said notches fx, see
Fig. 19, the opposite notch in said gear having pivoted in it by a pivot 17 one end
of a disengaging latch 18, the opposite downturned end of which enters the notch 17,
the said opposite end having also a projection 19, which at times may be acted upon
by cams 200 and 210 attached to a gate 22 of a stationary cam box or cover
surrounding the said gear and cam plate and loose on the shaft *.
During circular knitting the shaft is rotated continuously, and the gear in
operative engagement with the teeth of the thread carrier or ring, rotates the same;
and during circular knitting, the gate is open as shown in Fig. 1, it being held open
by a lever 24 pivoted at 25, the upper end of said lever, as herein shown, entering
a staple 26 attached to the said gate, the inner lower end of said lever, much the
heaviest, resting on the face of a disc 27, provided with a notch, see Fig. 18, a
spring 28*, see Fig. 1, acting on said lever to keep it down on said disc.
The heavier end of said lever enters the notch of the dise 27 just about as recip-
rocal knitting is to be commenced, and as the lever moves, it closes the said gate,
and brings the cams 200 and 210 attached thereto in such position that the cam 200
acts on the end 19 of the latch 18, and partially lifts the same, and at the same time
the clutch B is shifted to effect the oscillation of the main shaft for reciprocal
knitting and consequently the cam cylinder after having moved the shaft in one
direction reverses said shaft, and in its reverse movement the cam 210 of the gate
catches under the partially raised end 19 of the disengaging latch an lifts it fully
from engagement with the cam f, thus freeing the gear from the control of the
'

page_text: said cam, and enabling the said cam to reciprocate with the shaft, without rotating
the said gear and the thread carrier or ring.
As the cam 200 acts on the disengaging latch, the cam plate 27 acts to release
the lever, so that its upper end comes in range of and is struck by the pin 8 of the
slide, thus lifting it into position to be engaged and held by the latch / acted
upon by a spring /, said latch being pivoted upon a projection 20", connected to
the thread carrier or ring 73, carrying the heel and toe thread, and as soon as the
cam cylinder and the said ring are coupled together, as described, the said thread
carrier or ring is reciprocated with the said cam cylinder.
The link before described, see Fig. 16, has its inner end connected to an arm h,
fast on the vertical rock-shaft 4', said shaft having a-second arm A, to which is
joined a link 4, in turn shown as connected by two elbow levers 4, 4, a link and
a short rod ', with a cam 48, which actuates a clamp lever, through a spring 10,
said clamp lever being pivoted at 12 and being cut away to embrace the enlarged
end of a short stud h, to which is fixed an elbow lever 1, 1, see Figs. 1 and 1^,
and having its hearing in a part of the standard p2, one arm 4 of said lever having
adjustably attached to it a take-up device 4, acted upon by a suitable spring 4
attached at its free end to a rod x, projecting from the other or toe arm of said
lever, the latter arm being so located as to act on a pin 7, having attached to its
lower end one member of a thread clamp or tension device 418, the upper member
thereof being fixed to a short tubular guide 4, attached to the stationary frame.
.arm 21.
The pin 4 has a suitable shoulder, see dotted lines, Fig. 1, which rests on a spiral
spring located in said tube, the spring normally acting to keep the clamp closed
..on the thread used to knit the heel and toe, but in case of excessive strain on the
said thread, the take-up lever as it is drawn down causes the toe e to act on and
depresses the pin ", and open the clamp to permit the thread to pass freely.
The rock-shaft has a cam m, see Figs. 1, 18 and 23, which operates a lever m',
said lever being pivoted at 12 and having its opposite end pin-jointed to an L-shaped
slide 26, see Figs. 23 and 24, said slide baving at its underside near its outer end a
beveled or inclined part 27, see also Fig. 1, the said slide preparatory to again
commencing circular knitting being moved to put its inclined portion in line with the
upper side of the pin 8, to thus depress the slide fi and disconnect the thread carrier
or ring, leaving it at rest, and this done, the gate 22 is immediately opened to
enable the clutch 18 to again operate and start the ring for circular knitting.
While at rest, the said ring must be held or restrained from movement.
This is effected by a stop 28, see Figs. 17 and 18, said stop being pivoted at 29
and having a pin 30 which is acted upon by a lug 31, carried by said slide 26, said
stop in said Figs. 17 and 18 being in the position it will occupy when it acts to
hold the ring, the end of the said stop at such time acting against the bevelled
portion 32 of the projection 20* of the said ring.
The stop 28 is held in one or the other of its two positions by a spring-pressed
pin 33, engaging the pointed or notched end of said stop.
When the ring was again to be moved for reciprocal knitting, the slide 26 was
retracted and its lug was retired from the pin 30, and at substantially the same time
the slide was raised to engage the latch 2 and start the said ring, and as it
staried, the beveled portion 52, acted against the beveled portion 34 of the stop 28, to
.depress said stop and turn it on its pivot.
When the change is to be made from reciprocal to circular knitting, at which time
the take-up is not needed, the cam is turned in a direction to cause its part of
greatest throw to act on the spring 10 and cause the lever h° to clamp the stud h¹³
and hold the take-up-stationary and inactive wherever left as in Fig. 1.
To adapt the machine herein shown for the knitting of stockings connected
together, the web of stockings to be separated after having been taken from the
machine, it is only necessary to remove the link B connecting the lever B' to the
.elbow B*.
Now to use the machine to knit socks to. rib tops, the said link will be again

operating lever, substantially as described and shown by the drawings.
26. The combination and use in a knitting machine of the following instrumentalities,
a cam ring provided with cams, and a projection, a spring to move said ring in one
direction, and a trip to engage said projection, actuating means in connection with
said clutch to operate said trip and move it to turn said ring in opposition to said
spring preparatory to beginning circular knitting, substantially as described and
shown by the drawings.
27. The combination and use in a knitting machine of the following instrumentalities,
a cam cylinder, its switch to move out of and into action those needles not to be used
for reciprocal knitting, a gear attached to said switch, and a rack to actuate said gear,
and means to actuate said rack positively in two directions, substantially as described
and shown by the drawings.
28. The combination and use in a knitting machine of the following instrumentalities,
a cam cylinder, its switch to move out of and into action those needles which are not
to be used in reciprocal knitting, a gear attached to said switch and located outside the
cam cylinder, a rack plate to engage said gear, switch shifters, and means to put one

page_text: or the other of them into position to actuate said rack plate and move the switch in
the required distance, substantially as described and shown by the drawings.
29. The combination and use in a knitting machine of the following instrumentalities,
a needle cylinder, its lifting ring, a pattern surface having a cain, means to move said
pattern surface, and intermediate mechanism moved thereby to elevate said needle
cylinder immediately after completeing the toe to make a slack course, substantially
'as described and shown by the drawings.
30. The combination and use in a knitting machine of the following instrumentalities,
a needle cylinder, its lifting ring, a pattern surface having a cam, means to move said
pattern surface and intermediate mechanism moved thereby to elevate said needle
cylinder twice in succession immediately after completing the toe to make two
independent slack courses separated by usual knitting, substantially as described and
shown by the drawings.
31. The combination and use in a knitting machine of the following instrumentalities,
a ratchet wheel, its actuating pawl, and the clutch operating lever, mechanism inter-
mediate said lever and said pawl, and means to actuate said lever preparatory to
reciprocal knitting, whereby said pawl may be disengaged from said ratchet during
reciprocal knitting, substantially as described and shown by the drawings.
32. The combination, or arrangement of parts of a knitting machine wherein a
cam cylinder has both a rotary and a reciprocating motion so that the changes from
one to the other motion, to enable the circular part of a stocking, and then the heel or
toe part of a stocking to be knitted, may be made or effected entirely automatically,
substantially as hereinbefore described and shown by the drawings.
33. In a knitting machine of the class indicated the combination and use of two
thread carriers, preferably made as rings, each having its own independent thread, one
to feed the needles when circular work is being done, and the other to feed the needles
when reciprocal knitting is being done, as for heel and toe work, so as if desired to
put a thread of a different size, or colour from that of the leg into the heel and toe,
the said thread carriers being sustained on a support preferably independent of the
cam cylinder, said support being so made that it may be raised and turned aside from
above the top of the needles in the needle cylinder when it is desired to put a rib top
onto a stocking to be knit, means to operate and control or regulate the operation of
said carriers, a clamp to catch and hold the heel and toe thread at appropriate times,
whilst serving as a tension device when needed, means to effect changes from circular
to reciprocal knitting, and means for effecting selected changes in the motion of the
cam cylinder, and lengths of stitches, as well as to make one or more slack courses as
desired, or stop the machine, all substantially as and for the purpose set forth.
