IMPROVEMENTS IN KNITTING MACHINES cominunicated to me
from abroad by George Alexander Leighton and Samuel Caldwell Forsaith both of
Manchester New Hampshire United States of America
This Invention relates to circular knitting machines having plate and cylinder
needles adapted to produce different kinds of ribbed work as may be desired, and
to knit a commencing course suitable for a finish for the knitted fabric.
The object of the invention is to enable the changes in position of the different
cams which actuate the plate and cylinder needles, and also the needle cylinder, to
be controlled and effected automatically by a pattern surface when it is desired to
change from one to another kind of knitting.
The machine herein described embodying my invention contains a series of
plate and cylinder needles. The plate needles are operated by a series of cams and
cam switches having connected slide rods, the positions of which are changed
according to the requirements of the fabric through certain Jacquard cams to be
described moved by semi-circular slides provided with legs actuated by the
projections of the Jacquard chain, or pattern surface.
The cams and switch for controlling the movement of the cylinder needles and
for shogging the needle cylinder for the production of the commencing course to
serve for the finished end of the fabric, or to produce an ornamental border or
band, are also controlled as to their times of movement in like manner by the
Jacquard.

page_text: The Jacquard arrests the knitting devices just before the needle cylinder is to
be shogged for changes in knitting, and having determined the shogging of the
needle cylinder, the Jacquard again effects the starting of the knitting devices.
Instead of employing an independent thread for a separating course between two
articles, such for instance as cuffs or when part of one jacket is to be separated
from another, or to separate two different varieties of knitting, I employ one of
the threads of which the fabric is composed manipulating it by knitting only on
the plate needles, the cylinder needles then acting as sinkers, making preferably a
single course of plain web, the stitches of which will be subsequently cut.
My invention in knitting machine consists in a series of horizontal or plate
needles, and means to sustain and actuate them, a bed for cylinder needles, a series
of cylinder needles therein, a cam cylinder containing two grooves for the reception
of the butts of the cylinder needles, and a needle elevating can and stitch forming
cam combined with a switch fitted into the said cam cylinder and made moveable
vertically so as to cause the butts of the needles to travel in one or the other of
the said two grooves when it is. desired to produce Cardigan, or half Cardigan; or
one and one cuff or plain rib work, as will be described.
Also in a cam cylinder and needle bed and a series of cylinder needles therein,
combined with a series of plate needles, a cam plate provided with a drawing back
cam, a main throwing out cam, and an auxiliary throwing out cam to move
forward the butts of the plate-needles at the rear of the main throwing out cam,
as will be described, whereby the introduction of yarn into the hooks of all the
cylinder-and-plate-needles is insured during the first course after shogging the
cylinder needles for the commencing course of a cuff or other tubular-article-to be
knitted.
Also in a cam cylinder, and needle bed for cylinder needles, and cylinder neeilles,
a-series of plate needles, and two yarn guides one for each set of needles, combined
with a plate needle actuating cam provided with a drawing back cam, two
independent throwing out cams, and an auxiliary throwing out cam, to move
forward the butts of all the plate needles left at the rear of either of the throwing
out cams, to thus insure the introduction of yarn into the hooks of all the cylinder
and plate needles during the first course after shogging the cylinder needles, as
will be described.
Also in a cam cylinder provided with two grooves for the butts of the cylinder
needles, combined with two drawing down cams, and with an auxiliary drawing
down cam to draw down the cylinder needles in advance of the act of the usual
drawing down cams, to thereby lower the said needles out of the way of the
thread guide for the cylinder needles, when knitting plain rib work.
Also in a needle cylinder, cylinder needles, and cam cylinder provided with two
grooves for the reception of the butts of the said needles, and a reciprocating
switch, combined with a pattern surface and suitable intermediate connections

Figure 49 a side view of the taking up mechanism, and
Figures 50. 51 and 52 are details shewing in vertical section side and top view, a
modified form of bed and cylinder for the cylinder needles.
The bed A of the machine is mounted on suitable legs A¹ and connected with
the said bed and legs are suitable brackets and bearings to support the working
parts to be described.
The counter shaft B has on it a fast pulley B¹ and a loose pulley B³, which
receive at proper times the power belt B³, controlled by the forked arm of a belt
shipper B adapted to be liberated automatically to shift the belt B³ to the loose
pulley whenever the yarn is exhausted from the bobbins, or the work runs off the
needles of the machine.
The belt shipper near its handle has a pin B³, which is engaged, as in Figure 43,

page_text: operated upon by a bevilled stud B connected with a moveable semi-circular
slide Bs fitted into an annular groove of the bed plate A, see Figure 1.
Pins at or near the ends of the slide BS enter slots in each of two elbow levers Bº.
having their fulcra on pins secured to the bed plate, the longer ends of the said
levers being extended across a groove B¹º. made in the bed plate A just within the
groove which receives the slide B³.
Each bobbin C, will have a slot through its side wall and head to receive the end
of the detecting lever C, shown as an elbow lever, pivoted on the support C³, for
the bobbin as in Figure 2. Each lever O³, has pivoted upon its outer lower end a
rod C³, extended at its lower end through a hole in the yoke C. Each rod C³, has
a suitable spring C³, to draw, it down whenever the yarn on the bobbin fails to
keep the broad or blade like upper end of lever' C', in vertical position within the
slot made through the side of the bobbin. This lever C', is pivotted to move
outwardly only when the yarn upon the bobbin becomes exhausted.
The lever C, at the right of Figure 2 is in the position it will occupy when not
held up by the yarn, and the lower end of its rod C, will in such condition be
depressed into the groove B, so that the end of the said rod during the rotation
of the yoke C, will strike the end of the lever B. then its path will move the said
lever, and the latter will move its connected slide B³, causing the stud B7 to strike
and tip the latch B and release the shipper to be moved by its spring B¹
The axis or fulcrum B¹³, for the belt shipper has its bearing in a hanger B. The
shaft B has on its end a worm D which engages a worm wheel D*, on the shaft D¹
having at its end a cam D³. This cam actuates a lever D³, pivoted at D', and
having a pawl D³, which engages a ratchet wheel D, on the shaft D' which has
secured to it the usual fluted roller D8, between which and the pressure roller D
the knitted fabric is taken away from the machine. The fabric just at the rear of
the rollers DB. D. is acted upon by a roller D10, carried by a yoke D¹³, having hung
upon it a weight D¼, to enable the roll D's to exert the proper amount of tension
in the work.
The free end of this yoke is connected by rod D, with the lower end of a
lever De pivoted at D, the other end of the said lever being extended under the
latch Be before described.
Pawl Do will engage and operate ratchet De, only when sufficient fabric has been
knitted to require movement of take up, and when there is not sufficient goods to
be taken up the end of pawl D³, is kept from the ratchet by the pin D18 of
yoke D¹¹
When the work runs off the needles, the yoke D₁₁, drops and turns the lever D¹ª
to lift the latch and stop the machine as before described. Spring D¹s counter-
balances the weight of the rod D, the lower hooked end of which, see Figure 43
does not hold up the yoke D1, when the machine is delivering work properly.
The shaft B has on it a large fast pulley E, and a smaller fast pulley E, each
substantially twice as wide as the belt which it moves.
Pulley E by band E, on the small fast pulley E³, drives the main shaft E', of
the machine at its fastest speed. Pulley E' has a belt E³, which is extended about
the loose pulley E', on shaft E.
'
At the side of the fast pulley Es, is a loose pulley E³, of like diameter and at the
side of loose pulley E is a clutch pulley E8, of same diameter but recessed at one
side, see Figure 2 to fit a flange E fast on the main shaft.
The main shaft next the outer side of clutch .pulley E³, has loose on it a grooved
hub E10, embraced by the forked end of a pivotted lever E. The loose hub Elo
has attached to it a pin 2 which is entered loosely in a hole in pulley Es which pin
as the said hub is reciprocated on the sleeve G of the clutch pulley Es, by the
lever E, is withdrawn from the flange E° within the pulley E³, or placed in a hole
in the said flange.
When the pin is engaged with the Bange E the clutch pulley Es is clutched or
made fast on the main shaft, and vice versa.
When the machine is running at its highest speed, belt E³. is on the loose

page_text: pulley E, but when the speed of the machine is to be reduced, as when changes
are being made in the several operating cams, to be described, then the belt Es, is
shipped from the loose pulley Es, upon the fast pulley Es, and the belt E' from fast
pulley E on to loose pulley E. Such change of belts causes the Jacquard to be
operated one step of its chain at each revolution of the cam plate, whereas when
the belt is on the fast pulley E³. the said Jacquard is turned but one step at each
six revolutions of the cam plate.
The pattern surface of the Jacquard mechanism is shewn as two chains F. F.
.extended over sprocket wheels on the shaft F. Fs. The lower looped ends of the
chains are extended about like sprocket wheels F. carried by a yoke F³, made
adjustable by a screw F to thus keep the chains taut. Each chain contains pattern
bars on which are projections for one half the changes to be made, the chains
operating alternately.
The shafts F and Fs have at their ends toothed gears F' and F. which in practice
are engaged with each other. In Figure 2 the gear F7 is shewn broken out but
the line of its periphery is shewn by dotted lines. The shafts F' is driven positively
and moves the other with it by the gears referred to.
The shaft F3, at its rear end has a bevel pinion G shewn in Figures 38. 39 and
40 which is engaged by a larger bevel gear G¹ on a shaft G, having fixed on it a
ratchet wheel 12. Loose on this shaft is a pawl carrier G³, having a pawl Gʻ which
engages the ratchet 12 and moves the shaft G2, intermittingly.
This pawl carrier has a pin 5 at its upper end which supports two rolls or
discs 3:4-to-be-oporated upon respectively by the cam-wheels G. G. the former
having one, throw point, see Figure 47, and dotted lines 40; while the-latter_has
seven throw points.
The cam wheel Goalways acts against the roll 3 at each sixth rotation of the
cam plate of the machine, but the cam G. when it is in position to strike the roll
actuates the pawl carrier G³, and its pawl more frequently, as it is necessary to do
when the pattern chain is to be moved more frequently to effect the necessary
changes for knitting &c (as will be described from time to time).
The cam Go is fast on shaft Gs having at its outer end a worm gear Gº engaged
and rotated by a worm 7 on a short shaft Go having a bevel gear 8 which is
engaged with and driven from a bevel pinion 9 fixed to the hand wheel G¹³, which
latter as shewn in Figure 48 is fixed upon the long cylindrical sleeve G¹³, of the
clutch pulley E. before referred to.
The rolls of the pawl carrier G³ are held against their actuating cams by a
spiral spring 80, and reverse movement of ratchet 12 is, prevented by a detent 13.
When the clutch pin 2 is withdrawn from the flange E° by the forked lever E¹³,
as will be herein after described, and the belt drives the clutch pulley E then loose
on the main shaft, the pattern chain shaft will, through the shaft Gs, be turned
while the main shaft and knitting mechanism is at rest, at which time and by
which movement I am enabled to cause the Jacquard to effect the shogging of the
needle-cylinder as will be herein after described.
The cam G², loose on shaft Gs so as to be moved longitudinally thereon, is
connected with and so as to move in unison with the shaft Gs and cam Go, by a
pin 14 see Figures 2 and 46 extended from one side of cam G. Cam G7 at its side has
fixed to it an annularly grooved hub 15 which receives in its groove a forked
arm 16 loose on the sliding rod 17 provided with lug 18 which acts against the
hub of the arm 16 and moves it positively to separate the cams G. G. The
rod 17 has upon it a spring 19, the operation of which will be herein after
described.
When cam G' is in the position Figure 41 it is operative, or rather its periphery
travels in the space between the two rolls 3. 4 upon and does not actuate the pawl
.carrier G³, but when it is moved away from the cam G as when the belts E
and Es, are on the loose pulley E' and the cluteli pulley E8, then fast with relation
to the main shaft by the pin 2 and flange E then the cam G7 strikes the roll 4 and
actuates the pawl carrier' G. to move the pattern shafts more frequently.

page_text: The rod 17 has fixed upon it an arm H provided with a roll H³, (see Figure 41)
against which bears a projection or lug 88. of one of the pattern bars 88 see
Figure 41.
When the lug 88 strikes the said roll H2, the rod 17 is moved positively in the
direction of the arrow H, see Figure 41, and by the lever H" of the first order
moves the shipper rod H³, in the direction opposite the rod 17, causing the pins on
the said shipper rod, shewn in Figure 2 to move the belts E and E, upon the
pulleys E and E. as indicated in Figure 2 when the fast speed of the machine is
again resumed.
At the commencement of the movement of rod 17 in the direction of the
arrow H³, the roll 4 of the pawl carrier Gs, rested on one of the projections of
cam G' thereby producing sufficient friction between the said roll and cam to
practically prevent the sliding of rod 17 provided the arm 16 was fast on the
rod 17:
To enable this rod 17 to be moved at the exact time required to effect the
changes in the machine without unnecessary loss of time I had to place the hub
of the arm 16 on the rod 17 and provide the spring 19 to be compressed during the
movement of the said rod.
As soon as the belts arrive in the position Figure 2, the cam G7 having been
turned far enough to let the roll 4 drop from its projections, the spring 19 operates
to move the arm 16 and cam G7. quickly into the position Figure 41.
The revolving cam plate M is located in the open centre of the bed A and derives
its movement of rotation from a bevel pinion M, on the main shaft E'see Figure 3;
it engaging an annular series of teeth at the under side of the said cam plate all
as usual. The main shaft at its inner end, carries a bevel gear M³ which engages
a series of teeth at the under side of a loose ring M³ which has attached to it and
projecting upward and inward, two steel plates M*, see Figure 5 which support the
plate needles which are being reciprocated.-This is a common device.
The bed N for the cylinder or vertical needles 20, shown clearly in Figure 3 is
supported at its lower end by a disc N¹ loose on a spindle N2, fast on the yoke C
which is bolted to the upper side of the cam-plate M so that the said spinille as
the yoke is revolved with the plate M turns in the disc N¹ which rests on the
collar N³, fast to the said spindle, the pressure between the disc N' and lower end
of the bed N. being sufficient to prevent the disc N' from turning.
The cam cylinder P. for the vertical needles, and fast upon the spindle N*, has
two annular grooves N. No. shewn clearly in Figures 7. 8. and 10 which receive the
butts of the cylinder needles..
The cam cylinder P has a switch see Figure 7 composed of a block 21 having its
lower end beveled, and' a block 22 having its upper end parallel with one wall of
the groove N, and of a rod 23 to which the said blocks 21 and 22 are attached.
The said cam cylinder has also a knitting cam P2, for drawing down the cylinder
needles 20, the said can being connected with a rod 24 and has a needle elevating
cam Pio
When the switch is in its lowest position, as represented in full lines Figure 7,
the butts of the needles will be diverted from the upper groove N* into the lower
groove No. to enable cuff-work to be knit. This switch, in operation, has three
positions, two of which are designated in Figure 7 by dotted lines. The switch will
cccupy its second or next highest position, shown by dotted lines when the
separating course of yarn of plain knit work is being knitted, the cylinder needles
then descending from the upper into the said lower groove, but the cylinder needles
are drawn down only so far by the lower end of block 21, as to enable the yarn
supplied to the plate needle yarn carrier 25 to be drawn about the shanks of the
cylinder needles below their latches, so that after the cylinder needles are further
drawn down by the cams 26 and P. the loops of plate needle yarn will close the
latches of the cylinder needle as they are drawn below the loop of plate needle yarn
ön their shanks, permitting the said loops to be cast over the tops of the cylinder-

page_text: needles, thus making a plain or unribbed fabric, it being understood at this time
that the hooks of the cylinder needles are not supplied with yarn.
Referring to Figure 8 the cam f placed next to the drawing down can P,
draws all the cylinder needles down far enough to permit their latches to be closed
as usual after their hooks have been supplied with yarn, but not far enough to
cast off the loops on their shanks as that is done by cam P³.
The cam 26 which I shall call the auxiliary drawing down cam, see Figure 7 is
.so located as to slightly depress the cylinder needles in advance of the cams f
and P, as the change is being made from cardigan to plain or one and one rib
stitch.
•
When plain knitting is being done the butts of the cylinder needles travel under
cams 2620, and P2, along up over the lifting cam P10 along groove N. and against
the inclined lower end of the upper block 21 of the switch, thence into the lower
groove N³, but when cardigan stitch knitting is being done the butts of the said
needles pass into groove N and along above cam 26, thence along under cams ₤20,
and P2, up over cam P10, and straight along groove N the switch 21, 22 being
then fully elevated.
The switch of the cam cylinder occupies its second or intermediate position
however, for but a single rotation of the cam cylinder, and the single course knitted
at such time by the plate needles with its regular thread will be subsequently cut
and drawn out to separate the fabric knitted when the switch was previously in
its lowest position from the fabric knitted when the switch occupied its highest
position.
When the said switch-is-in its highest position the upper end of block 22 will
close the gap in the lower wall of groove N and when being lifted-from-its-lowest
full line position into its highest position as shewn in dotted lines, the upper end
of the block 22 will act to lift the butts of all needles then above it into the line
of the groove N, and so long as the switch occupies its highest position the butts
of the needles 20 will travel in the upper groove and will not be reciprocated by
the switch, but will be raised and lowered by the usual cams PI⁰ and P
.
The switch will be in highest position when Cardigan or half Cardigan work is
being knitted, the vertical needles at such times being kept elevated while opposite
the plate needle yarn guide, that the plate needles 27, may draw the yarn of the
plate needle yarn guide about the shanks of the cylinder needles below their
latches, but these cylinder needles employed in knitting Cardigan or half Cardigan
work will have yarn introduced into their hooks by their own yarn guide before
their butts are acted upon by the drawing down cam P2 so that as the cylinder
.needles come into the groove N°. the plate needle yarn about the shanks of the
.cylinder needles below their latches will close the said latches and imprison in the
hooks of the cylinder, needles the loops of yarn supplied thereto by the cylinder
needle yarn guide, the said loops of plate needle yarn being cast off over the tops
of the cylinder needles.
The cam plate M see Figure 11, has at its under side a drawing in cam 29 an
auxiliary throwing out cam 30 and two pivoted throwing out cams or cam
switches 31 and 132.
The switch cams 31 and 132 when they are in action divert the butts of the plate
-needles from the groove 33 into the groove 34.
As shown in Figure 11 in full lines, all the said cams are in position to permit
the needle cylinder to be shogged the distance of one needle.
The butts of the plate needles travel in the groove 34, when cam 132 is in
operative position as in dotted lines Figure 11, to do full Cardigan work cam 31
being also in dotted line position. When plain knitting, or one and one rib
work is being done, the cam 31 being in its dotted line position, the cam 132 will
preferably be in its full line position the needles then passing into groove 33 at
the rear of cam 132 and again into groove 34 past the cam 31.
While the machine is knitting Cardigan, half Cardigan, or one and one rib work

page_text: the auxiliary throwing out cam 30 occupies its dotted line position. Two threads
are used in half Cardigan, full Cardigan and one thread in one and one or plain
cuff work.
The throwing out 31 if stationary would be as common in other machines
but herein it is pivoted to serve as a switch, and it has connected with it suitable
devices as herein after described to move it into its full and dotted line positions
it being in its full line position when the plate needles are being drawn back or
put into position to permit the needle cylinder and cylinder needles holding loops
of plate needle yarn to be shogged or moved past the end of the plate needles, at
which time the auxiliary throwing out cam 30 occupies its full line position.
Let it be supposed that the main part of a sleeve has been knitted up to each
shoulder, by both series of needles, each with its own thread and operated as usual
for the production of full Cardigan work, the cams 31, 132 and 30 all then
occupying their dotted line positions.
If it be desired to commence a cuff for a new sleeve with only the yarn taken
from the plate needle yarn guide, and provide the cuff with a finished commencing
course, I move the switch cam 21, 22 into its intermediate position previously
described and cam 132, into its full line position and the machine being then
turned one revolution, the cylinder needles will be so lowered as to fail to take
yarn from the cylinder needle yarn guide and the plate needles supplied with yarn
from their own yarn guide will be drawn back into groove 33 by cam 132 and
arriving at cam 31, it being in dotted line position, the plate needles, will be
directed into groove 34, and at this same time the plate neodles as they are drawn
back by cam 29 will draw the loops of plate needle yarn across the shank of the
cylinder needles below their latches, and the loops so drawn about the cylinder
needles are subsequently cast off.
The single revolution of the machine being completed as described, the cam
switch-21. 22 Figure 7 will be moved into its lowest position, and the machine will
be started and the plate-needles will draw the loops of their yarn about the latches
of the cylinder needles instead of below their latches as before, and the machine
will be revolved until all the plate needles are moved outward adjacent to those
vertical or cylinder needles which have loops of plate needle yarn about their
shanks. At this time the cams 30 and 31 will be moved into their full line
position, as will be herein after described, when in the further rotation of the
machine the plate needles will be drawn back by the cam 29 until the last plate
needle to receive yarn is drawn back from between the cylinder needles, in which
position the cams will be as in Figure 11 full lines and the needle cylinder and its
needles may be shogged.
-
This shogging of the needle cylinder and its needles so crosses and draws the
loops of plate needle yarn held by both sets of needles so as to make a finishing or
commencing course for the end of the cuff or article.
To knit the second or succeeding courses to form the cuff, the cams 30 and 31
immediately after shogging the needle cylinder as described, will be moved into
their dotted line positions, which will cause the plate needles to be thrown out far
enough to take yarn from the plate needle yarn guide, but were it not for the
auxiliary throwing out cam 30, which is then put into its dotted line position the
plate needles at the rear of cam 31 and in advance of cam 29 in the groove 33
would fail to be thrown out far enough to receive yarn from the plato needle
yarn guide:
If it is desired to knit cuff work or half Cardigan work the switch cam 31 and
auxiliary throwing out cam 30 will be put into their dotted line positions and if
it be then desired to knit full Cardigan the switch cam 132 will be put into its
dotted line position.
The auxiliary throwing out cam occupies its full line position only when the .
cylinder is to be shogged, it being placed in such position before shogging the
cylinder to enable the butts of the plate needles in advance of it to remain in
the groove 33 of greatest diameter, which keeps the plate-needles drawn in, and

page_text: •
immediately after shogging the cylinder, the auxiliary throwing out cam 30 will
be moved into its dotted line position throwing out bodily the butts of the needles
then in front of it, which enable them to have yarn supplied to their hooks by the
plate needle yarn guide 25 before the butts of the said needles are acted upon by
the drawing-in or knitting cam 29.
After the cam 30 is moved into its dotted line position, but before the cam-
plate M completes its rotation, the switch-cam 31 will be moved into its dotted line
position to throw out the plate needles just before they arrive at the latch opening
portion of the plate needle yarn guide 25 in order that the latches of the plate
needles may be properly opened for the reception of yarn therefrom.
The cam plate M has attached to it two lifters w2w located near the point of
the cams 132 and 31 to obviate excessive backward movement of the butts of the
needles and strain on their loops.
In other knitting machines when knitting was to be changed from Cardigan to
plain one and one stitch, or vice versa, it has been necessary to adjust the position
of the cylinder needle yarn guide 28, to get it out of the way of the cylinder
needles as they are brought into position to do one and one rib work, or to put
into position to supply the elevated cylinder needles with yarn.
Herein I have obviated such adjustment by providing the cam cylinder for
actuating the cylinder needle with an auxiliary cylinder needle depressing cam 26;
Figure 7 arranged in advance of the usual knitting cam P, the cam 26 acting
to draw down the cylinder-needles sufficiently to obviate striking the cylinder
needle, yarn guide.
Each of the cams and switch cams of the cam plate and the switch and cam of
the cam cylinder, are in this my-invention to be shifted automatically. Each of
these cams and switch cams, and the switch has connected with it a slide bar
which will be moved at the proper times as I will now proceed to describe, by-cams
which I shall denominate Jacquard-cams for the reason that they are put into one or
other of their operative positions through the instrumentality of the pattern surface
or chains referred to.
The stationary bed A. shewn in top view Figure 1 and partially in Figures 20
and 21 has, it will be noticed, a series of concentric grooves which receives a series
of arc shaped slides a. b. c. d. e, having respectively legs a¹. b. c¹. d¹. e¹. see
Figure 38.
The slide a at one end, has a diagonal slot a³. see Figure 30 and in dotted
lines Figure 29 which receives a roller pin a³, projected downward from the
sliding block at having attached to its upper side by screws, the two cams a³. a.
The block a is fitted between guides a. of a plate attached to the bed A by
screws a³.
The cams a³. a. Figure 29 are employed to shift the drawing in or knitting
cam 29 of the cam- plate. The cam 29 has at its upper side a screw stud a³.
extended up through a slot in the cam plate M.
The stud a'. is engaged by one end of the elbow lever at the long arm of which
is made to enter a transverse slot in the underside of the slide rod a¹. seo
Figure 31 fitted into a guide box a¹³. secured upon the top of the cam plate M.
The slide bar a. at its' outer end, has a roller stud a. which strikes against one
or the other of the cams as aº. when placed in the path of movement of the said
roller-stud, by the pattern-surface.
When the slide rod a¹. is in the position represented in full lines Figures 29
and 31, the knitting cam 29 will occupy its dotted line position Figure 11, and the
plate needles will be drawn to produce the maximum length of stitch, but when
the said cam 29 is as in full lines Figure 11. the slide rod a¹. will be in the
position shewn by dotted lines Figure 30, and full lines Figure 1.
If it is desired to change the position of the sliding block at. so as to move the
cam 29 into its full line position Figure 11 to draw a short loop one of the
projections a near the end of one of the bars t. of the pattern chain F will strike
the leg of and push the arc shaped slide c'in the direction of the arrow als

page_text: Figure 1 far enough to move the sliding block at and place the cams a³. and aº.
into the dotted line position Figure 29 so that during the rotation of the cam plate
the roller stud a. on the slide rod a¹. it then occupying the full line position, will
strike the cam a. which will at once draw the said slide rod into its dotted line
position and place cam 29 in its full line position.
The cams a. and a. will remain in this dotted line position until the cam 29 is
to be again changed, the roller stud moving freely through the open space between
the said cams and the slide rod a¹, which it will be noticed is-toothed at its upper
side as at a. will be held in place by one of the slide-rod locking catches or
springs a¹8 or a". the ends of which are. hooked to enter the spaces or notches
between the said teeth.
When the bent or hooked end of one of the said catches enters one of the said
notches, the bent or hooked end of the other of said catches will rest upon the top
of a tooth next to the notch then entered by one catch.
By the employment of the two catches one to enter a notch and the other to rest
upon a tooth as described, I am enabled to make finer adjustments than by the
employment of but one spring.
The slide rod a. at its front side has attached to it by screws a. a catch lifting
slide a provided with a ball a". which when the catches a", and a¹. are to be
lifted to permit the 'slide rod a¹. to be shifted will first strike against that one of
the cams a. a. then in operative position which will move the catch lifting
slide a. longitudinally on the slide rod. a. before the roller stud a¹ of the said
slide rod strikes the said cam.
The movement of the said catch lifting slide in advance causes one or the other
of the inclines on it, shewn in Figure 32 to act upon one or the other of the
inclined edges of a finger a. which rests on a depression of the said lifting slide.
between the inclined edges, and causes one or the other of the said edges to lift tho
finger, so that it acting against the underside lifts that one of the catches a¹8 or a¹º.
which is then engaged with a notched part of slide rod a¹. leaving the said
slide rod free to be moved longitudinally as soon as the roller a strikes the
cam a³, or a®, which is then in operative position.
When the roller stud a¹ of the slide rod a reaches a position between the two
parallel walls of the two cams a³. a. (the roller a of the lifting slide a". having
been held from longitudinal movement by the parallel walls of the cams a³. a.
while the slide was being moved longitudinally) it will be observed that the
relative longitudinal positions of the slide rod and the catch lifting slide will have
been changed sufficiently to again bring the notched part of the lifting slide
directly under the finger so that it is permitted to fall and with it the catches
above it, that one of the catches which was upon the top of a tooth then dropping
into a notch between the said tooth and the one next to it.
Each of the slide rods herein employed will have one or two locking catches such
as described, and a catch lifting slide to disengage it from the toothed part of the
slide rod with which it is adapted to co operate, so I will not herein further
describe such devices, nor do 1 consider it necessary to letter the said parts in the
other Figures.
When the slide block a is to be moved to move the cams a³. a. from their
dotted to their full line position Figure 29, the leg a'. of the arc shaped slide c will'
be acted upon by a suitable projection 35 of the chain F.
Each projection a* or 35 to effect the change of loop as described will be
made adjustable on the bars t. of the chains by means of set screws 36, so that
the arc shaped slide may be moved more or less, and so place the cams a. or aº.
that more or less of their inclined faces may operate to move the slide rod more or
less according to the distance it is desired to move the drawing in cam 29.
The auxiliary throwing out cam 30 has a screw pin or stud b³, see Figure 27 which
is passed up through a slot b³, in the cam plate M and into a slide rod b' held in a
guide box b. The said slide rod b. at its outer end has a roller stud b. which acts
to draw the slide-rod b*. outward and place the auxiliary throwing out cam 50 in

page_text: its full line position preparatory to shogging the needle cylinder N. The roller
stud 6. acts against one edge of the cam link 31 when the latter is in the position
shown in Figure 21 and in dotted lines. Figure 22.
As soon as the roller stud 66. it having passed beyond the cam link 81, reaches a
position opposite the cam 7. it occupying the position shewn in Figures 21 and 28
during the shogging of the needle cylinder, the slide block 32 to which the said
cam 67. is screwed, is moved inward, toward the centre of the cam plate by means
of the arc shaped slide d. which as described of arc shaped slide a.. has near its end
a diagonal or cam slot shown in dotted lines Figure 28 to receive a downwardly
extended roller pin 33 carried by the slide block 32.
The arc shaped slide d. will have its leg d'. acted upon at opposite edges in the
proper order by suitable projections on the face of the pattern chains F. F'.
The switch before described as forming part of the cam cylinder P, fully shewn
in Figure 7 is automatically operated by the slide rod c². held in the guido box bo,
at the side of the slide rod 6. The slide rod c. at its inner end, has a diagonal
slot c³, into which is entered the roller stud c, of a clainp block c³, securely
clamped upon the 23 of the said switch.
The slide rod c², at its outer end has a rollér stud c. which, during the rotation
of the can plate M will act upon the edges of the can links c. c. which ever link
may be placed in operative position in accordance with the projections of the
pattern-chain.
When the slide rod c². is in the position shown in Figures 1. 25 and 26 the
switch will be in its highest dotted line-position Figure 7 to enable the machine to
knit Cardigan or half Cardigan as before described. If the said switch is to
remain in its highest position, the cam links c'. c8 will remain as shewn in full lines
Figures 1 and 25 and the roller stud c. will pass freely between the cam links
c. c. but if the said switch is to be lowered one step as when introducing the
separating course of yarn taken from the plate needle thread guide, the cam links
c. c. will be turned into dotted line positions Figure 25 before the roller
stud creaches them, so that the said stud will strike one edge of the cam link c².
The switch will ordinarily be held in its intermediate position last referred to
form but one course, when the cain links c c. will be put into their full line
positions Figure 28 so that the roller stud c. during the next revolution of the cam
plate M will strike the edge of the cam link c. it then being placed at a greater
angle than in dotted lines Figure 25 which will cause the slide rod to be moved
yet further inward toward the centre of the cam plate to put the switch into its
lowest or full line position Figure 7 to enable the machine to knit cuff work, or
one and one rib work with the plate needles, and the yarn of the plate needle.
yarn guide, the said plate needles drawing the said yarn about and into the hooks
of the cylinder needles as usual.
Each cam link c. and c. at one end is pivoted to a slide block c³. in line with
the slide block 32, both of which blocks are fitted to slide in the same guides 35.
The other ends of the cam links c. c are slotted as shewn in Figures 25 and 28,
to fit over stationary pins 36, 37 fixed to the guide 35.
The slide block c. has at its under side a roller stud shewn in dotted lines
Figure 28. which enters a diagonal slot, also therein shown in dotted lines, made in
the arc shaped slide e, the leg el. of which is acted upon at one or the other of its
edges, or roll thereon, by suitable projections arranged upon the bars t. of the two
pattern chains F. F
The switch cam 31, see Figure 11, which when in its temporary full line
position retains the butts of the plate needles in the groove 33 of greatest diameter,
the auxiliary cam 30 then occupying its full line position Figure 11, has a stud or
screw 38 which is extended up through a slot in the cam plate M, as shewn in
Figure 22 where it is engaged by a lever 39, the other end of which, extended
through an opening at one side of the guide-box 40 enters a recess formed at the
lower side of the slide rod d³, the said recess being sufficiently large to admit of
-lost motion as will be described.

page_text: The slide rod d..has a roller stud d³ which when the switch cam 31 is in its
dotted line position, the machine then knitting regularly and the auxiliary
throwing out cam being in its dotted line position Figure 11 will pass freely
between and not be actuated by the cam links 31 and 41.
When the slide rod d. is in its full line position Figure 22, and the switch
cam 30 is in its, dotted line position, if it is desired to then place the said switch
cam temporarily in its full line position Figure 11, the slide block d. fitted into
guides d³. will be moved by the arc shaped slide d, it having a suitable diagonal
slot shown in Figure 22, which acts on a roller stud at the under side of the said
block d. to place the can links 81. 41 in their positions shewn by dotted lines
Figure 22 and full lines Figure 21 when the roller stud d³, will strike the edge of
the cam link 31 which acting as a cam will draw the slide bar outward into
its dotted line position Figure 22 where it will remain for one revolution of the
cam plate M when the roller stud ḍª will strike the edge of cam link 41 which
during each one revolution or nearly so, of the cam plate M has been changed
from its dotted to its full line position Figure 22.
The knitting-cam P². of the cam cylinder, fully shewn in Figure 8 has a rod 24
which is embraced by a clamp 42 see Figures 34 and 35 having a roller stud 43,
which is entered into a slot 44 at the end of the slide rod f fitted into the
guide box f¹. secured to cam plate M.
The outer end of slide rod f is provided with a roller stud ƒ³. such as common to
the other slide rods, which at proper times strikes one or the other of the cams
ff or passes freely between them if the cam P³, is not to be raised or lowered.
With the slide rod fin its full line position, Figure 34 the cam P2 will occupy its
full line position Figure 8, to thus draw loops of greatest length, and so long as
the cams f. f. occupy their full line position Figure 34, said slide rod will not
-be changed.
If it be desired to draw shorter loops of yarn by means of the cylinder needles,
the cams ff will be moved into their dotted line positions Figure 34 when the
roller stud at the end of the slide rod f. will strike the cam f³. which will move
the slide rod f. outward into its dotted line position.
These cams f. f. are secured to a cam block f. fitted into guides fº secured
to the bed A. The block f. will have at its under side a suitable roller stud to
enter a diagonal slot in the arc shaped slide b. the said stud and slot being
represented in dotted lines Figure 34.
The leg 6', of slide 6 or the roll at its lower end will be struck at the proper
times by suitable projections of the pattern chains F. F'. so as to move the said
arc shaped slide positively in either of its two directions, and the said projections
of the said pattern chains as described, of the projections a*. and 35 will preferably
be made adjustable so that the cams f* and f' may occupy any desired
intermediate positions between their full and dotted line positions shewn in
Figure 34.
The loops of yarn drawn by the cylinder needles from the cylinder needle yarn
guide will be lengthened automatically when changing from cuff to Cardigan or
half Cardigan. Heretofore whenever it has been desired to separate two knitted
tubular articles made in succession, one of which is to present a finished end, it has
always been customary to introduce one or more courses of a different thread usually
a smooth cotton thread temporarily tied on the regular yarn, which cotton thread
was thereafter withdrawn.
I have discovered that tubular ribbed knitted fabrics will not unravel on the
machine, provided the last or next to the last terminating course of the fabric is
knitted with the Oardigan or half Cardigan stitch, two yarns being then used and
that the loops formed from the yarn taken by the cylinder needle from the cylinder
needle yarn guide brought into operation for Cardigan work, be drawn by the said
cylinder needles to produce a course of long loop or loops of an extreme length and
that to separate the terminating end of said fabric from the fabric next to. be
commenced and ended on the machine I need not introduce a separate cotton

page_text: thread as heretofore, but may introduce instead, one course of thread from the
regular yarn of the plate needle thread guide, the said course being however knitted
entirely by the plate needles, the cylinder needles then acting as sinkers and
forming one course of plain web such as would be produced in a circular knitting
machine containing but one set of needles:
The switch cam 132 see Figure 11 has a pin 46 which is extended up through. a
slot in the cam plate M as in Figure 37, and into a hole in a slide rod g which
latter fitted into a guide box g¹. attached to the plate M has a roller stud g². which
as the cam plate M is rotated causes the said roller stud to strike one or the other
of two cams g³.g. attached to a cam block g³. fitted into the guide ge. or enables the
said roller to pass between the said cams freely.
When the switch cam 132 is in its full line position Figure 11 the machine then
knitting half Cardigan or one and one rib work, the slide rod g will occupy the full
line position Figure 36, but when the said switch is in its dotted line position, the
slide rod g will be as in full lines Figure 1 and as in dotted lines 36.
•
To change the switch 132 from its full to its dotted line position to knit
Cardigan work, the cams g³. g. will be moved into their dotted line positions
Figures 36, so that the roller stud g³. will strike the cam g². which will draw the
'slide rod g outward into the dotted line position Figure 36 or into the full lino
position Figure 1.
Subsequent movement of the cams g³. g. back into the full line position Figure 36
will effect the movement of the slide rod g in the opposite direction, or back into
its full line position Figure 36.
The slide block g. has at its under-side-a-pin-which-enters a diagonal slot, see
dotted lines Figure 36 made in the arc shaped slide c. having a leg c. provided with
a roll which is acted upon at the desired times by suitable projections on the.
pattern chains F. F¹. according to the direction it is desired to move the said
slide c. or the slide block g.
Having knitted the one plain course referred to with the regular yarn taken
from the plate needle yarn guide, the next course in succession will enter into and
form part of the next article to be knitted, which will be supposed to be cuff
knitted with the rib stitch both sets of needles being then employed the yarn being
delivered from the plate needle yarn guide.
To so manipulate this course that the commencing course shall serve as a finish
for the end of the cuff joined with the separating course and obviate hand finishing,
I shog the needle cylinder to the right or left the distance of one neodle.
This is done at the end of the first course after the introduction of the separating
course referred to, and the second and other succeeding courses of the cuff will be
knitted with the cylinder needles in their shogged positions, or if it is desired to
produce a series of crossed loops, to serve as an ornamental border the needle
cylinder may be shogged in the opposite direction at the end of one or more
courses.
By cutting the separating course, the cuff just referred to may be separated
from the article previously knitted and with which it is joined by the separating
course.
The cylinder N¹ has at opposite sides two dogs 47. 48 which are embraced by
the forks 49, secured by bolts 50, upon the ring 51, fitted into an annular recess at
the under side of the bed M for the plate needles, see Figure 3 the said ring 51
being retained in its recess by bottoms m².
The ring has connected with it an arm 52, shown best in Figure 38 having a
roll 53, see Figure 39 where the arm 52 is shewn in section. The roll 53 is placed
between the peripheries of the two cylinder shogging cams 54. 55 see Figure 59
and separately in Figures 44 and 45 which latter Figures shew the opposite sides
and edges of the said cains:
The peripheries of the cams 54, 55. act against the roll 53 and move the cam
and needle cylinder in one or the other direction as may be desired

page_text: wheels by which the chains F. F¹. are suspended and moved. Each cam 54. and
55 at its rear side is provided with two dogs having square ends and secured to
the cams so that they will be in the path of movement of the projecting. ends 58
of some of the bars of the pattern chains see Figure 33 so that the ends 58 of said
bars will, at the proper times, strike the dogs and turn the said cams intermittingly
for half a revolution, the part of greatest radius of ono of the said cams being
always opposite a part of the other cam of least radius, so that the two cams by.
their joint operation will hold the roller 53 steadily moving the needle cylinder.
positively in either direction and hold it in place against accidental movement.
The cam 54 has two side inclines 58, 59 and the cam 55 has two lifting cams
60, 61; :
The cams 54, and 55 as shewn in Figure 39, are in the position they will occupy
when the machine is knitting regularly the cam plate then rotating.
1
As described in the early part of this Specification, the knitting mechanism must
be entirely stopped while the needle cylinder is being shogged but at such time the
motion of the Jacquard chain is continued.
To effect this the machine is provided with a rock shaft 62 see Figure 39 having
two arms 63 and 64. The arm 63 at its outer end is connected with a pin 65
which is projected up through a hole in the bed A by the spring 66 see Figures 38
and 39 just before or as the stop J see Figure 11 connected with the under side of
the cam plate M reaches a position in the movement of the said cam plate near the
said hole so that the upper end of the said pin is struck. by the said stop J, and
rotation of the cam plate is arrested.
The spring 66 assumes control of the rock shaft as soon as the end of its arm 64
arrives at the end of the cam 60.
While the cam 55 is being rotated, one of the.side cams 58 or 59 of the cam 54
it being rotated at the same speed as cam 55 acts against the inclined end of the
plungern, held in the bearing n³.
The front end of the plunger n, is slotted to receive loosely the wedge n, the
opposite end of which is inserted in a slot made in the end of a short pin 67 held
in the yoke 69 and pressed outward by the spring 68.
The upper edge of the wedge n³. when pushed toward the right in Figure 38
acts upon the lower end of and lifts the pin n³.
The stop J see Figures 38 and 12 is inclined so that as the forward end of the
said stop comes in contact with the upper end of the elevated pin no, it will depress
the same, the wedge n³. then descending with it owing to its peculiar connection
with the plunger n and the inner edge of the said wedge by its action against the
upper end of the pin n'. which at its lower end rests upon one arm of the bell
crank lever n. turns the said bell crank lever n². and moves horizontally the
rod n³. which at its other end is joined with the lever E"; which embraces the
collar Elo, and by the movement of the said collar disconnects the clutch pulley E³,
from the flange E° fixed to the main shaft.
Just as the pin 2 of the collar is withdrawn from the flange E° the front end of
the stop J arrives against the pin 65 before referred to and the knitting parts of
the machine are instantly stopped, but the clutch pulley Es continues to revolve as
the belt E³. is then on it, and as described in the early part of this Specification the
motion of the pattern chain is continued.
The continued rotation of the cams 55 and 54 carries the cam 61 into position
to strike the rear end of arm 64 of the rock shaft 62 causing the arm 63 to pull
down the pin 05 away from the stop J, and at the same time, or substantially so,
the side cam 59 passes the end of the plunger n, permitting the spring 68 to act.
to push the wedge n³. and plunger n, toward the left in Figure 38 which permits
the spring p see Figure 2 to operate the rod n³ and lever E¹ to actuate the collar
and pin 2 for the latter to engage the flange E³, when the rotation of the main shaft
will be again resumed.
The latch opener, for the cylinder needles is lettered r. and is shewn clearly in
Figures 4 and 5. It operates as usual.

page_text: When one and one rib knitting for a cuff is to follow Cardigan or half Cardigan
work, the one and one rib knitting employing but one thread while in Cardigan
and half Cardigan two threads are used as described the yarn supplied by the
cylinder needle yarn guide to the hook of the cylinder needles, must be cut off
between the said yarn guide and the fabric. just after the cylinder-needles are
lowered, by the passage of their butts down through the switch 21. 22 into the
groove Ns where they cease to be supplied by yarn from the cylinder needle yarn.
guide. By drawing down the cylinder needles in this way their hooks are enabled
to pass below the cylinder needle yarn-guide.
d
The yarn from the cylinder needle yarn guide is drawn by the revolution of the
cam plate M directly between the blades of a thread cutter s³, sce Figure 15 and
the end of the yarn next the yarn guide is held between the forked spring 8³, at
the rear side of the rod 8, with which the cutter is attached.
As soon as the cylinder needles are again worked regularly and the switch 21, 22
is in its highest position the cylinder needles in their descent catch the yarn of the
cylinder needle yarn guide, it being then held by the spring 83. and knitting will be
resumed by the cylinder needles with the said yarn.
L
The key 70 Figures 13 and 11 permit the introduction and removal of the plate
needles and the key 71, Figures 19 and 5, permits the introduction and removal. of
the cylinder needles. The usual support 73 for the plate needles connected with
the shank 74 is shewn in Figures. 18 and 5.
The edges of the links 31, 41. c. and c. form cams or inclines and I therefore
denominate them cam links. I prefer these cam links: to stationary cams such for.
instance as f; and f. for the reason that they occupy less space. Instead of the
particular pattern surface herein employed I may use any other well known form
of pattern surface, and by change of the projections of the pattern surface I may
control the movement of the various cams and the times of shogging the needle
cylinder according to the class of work being done.
The take up mechanism is operated by the counter, or power driven shaft B,'the
pulleys on which drive the main shaft and the knitting devices, which enables the
strain on the main shaft to be maintained more nearly equal than were the take-up
devices driven by the main shaft as heretofore. ..
In half Cardigan work, two threads being used, the yarn supplied to the
cylinder needles is manipulated by the said needles as in regular- or plain knitting
with only one set of needles, but the yarn supplied to the plate needles is at such.
time held about and between the vertical or cylinder needles below their latches,
so that as the vertical or cylinder needles descend with loops of their own thread
they draw such loops down through the loops of their own thread, then on their
shanks below their latches, and at the same time draw. the said new loops through
the loops of the yarn then held by the hooks of the plate needles and extended
across and between the vertical needles as described, and both of the said, loops are
cast off the tops of the cylinder needles, and the cylinder needles at the termination
of their next upward stroke have but one loop, viz, that of their own thread, such
loop being below their latches:
In full Cardigan work, however; the: yarn supplied to the cylinder needles is
drawn over.between and about the plate needles back of their latches, and the
yarn supplied to the plate needles is drawn.about the cylinder.needles.below. their.
latches as in half. Cardigan.

In full Cardigan each needle of both sets of neodles has two loops below its
latch, when descending or drawing.in, whereas in half Cardigan, the plate needleś
have but one. such set of loops.
ง
In full Cardigan both sides of the fabric are alike, the yarn supplied to the
cylinder needles appearing on. the inner side of the fabric and that to the plate
needles on the outer side of the fabric, but in half Cardigan work the outside of
the fabric is ribbed and the inner side is flat.

Thus it will be seen to make Cardigan or half:Cardigan two independent threads
must always be used, each with its own set of needles; enchy thread having its own

alternately into the hooks of both sets of needles.

One and one or single rib work presents single longitudinal rows of knitted loops
turned in opposite directions, and double ribbed work presents a series of two
adjacent rows of such knitted loops turned in one or the same direction, and each
series of two loops being separated by a single longitudinal row of loops turned
in the opposite direction.
In large sized machines I prefer to make the cylinder P for the vertical needles
as a shell, or hollow, as shewn in Figures 50 to 52. The wall of this hollow cylinder
or shell is provided with a removable cam holding segment such as shown at 102,
upon which will be suitably secured, or in which will be guided the cams or
devices which determine the reciprocation of the cylinder-needles for knitting.
When the butt of a needle sticks at the cam for operating it, the needle may be
quickly and easily removed by simply removing the segment 102, and this may be
done without removing. the work from the needles, whereas in other machines
to remove a stuck needle it is necessary to cut off the work, remove the hub from
within the needle-bed, and remove all the needles, which have to be again replaced
before the knitting can be resumed.
The section 102 has a flange or foot piece 103 provided with holes for the receipt
of screws. 104, by which to secure the section to the cylinder shell P.
