Improvements in Knitting Machines.
I, JOHN THOMAS HARRIS, of 121, Tipping Street, Ardwick, Manchester, in the
County of Lancaster, Knitting machine salesman, do hereby declare the nature of
this invention to be as follows:-
This invention relates chiefly to circular knitting machines, though parts are also
applicable to straight machines.
The object of the invention is to provide for the narrowing or fashioning of a plain
stocking on the same machine as that for making a rib stocking or for making
divisions by withdrawing certain of the needles clear of the cams, thus allowing for
the manufacture of two classes of stocking upon one machine, to provide a circular
machine for the manufacture of undervests ribbed or plain, and to provide for the
knitting of two or more courses at the same time.
In carrying out the invention I construct the bed platesome what of L shape in
cross section with a recess to receive the teeth of the carriage and two shoulders upon
which the carriage rests and revolves. The carriage thus fits into an annular seating
formed between an upright flange or shoulder at the outside edge of the bed and the
vertical back part thereof. It is held in position by a ring secured to the vertical
side of the bed above its top edge and by suitable slotted clamps, screws or the like
placed at intervals to prevent it rising. The bed is also fitted with a flange or lugs on
the vertical side to carry the needle cylinder.
The arm or socket for carrying the driving wheel and handle is made separate from,
and attached to the bed by screws, or bolts, so that it may be changed to carry a
driving wheel of any size.
The carriage in cross section is also of shape to fit upon and around the shaped
bed upon which it revolves and is provided with driving teeth on the under surface in
the usual way.
The needle cylinder is made longer than usual and is mounted upon the upper
flange or lugs on the vertical side of the bed. Below the shoulder it is cut away to
a depth of say about 1 to 2 inches, and is there provided with a ring in sections upon
which the ends of the needles rest. At or near the top it is also cut away to receive
a slotted ring which encompasses the vertical needles and holds them from falling out
of position.
The needle rest which fits below the shoulder is made in sections of say 2 inches
long each to maintain a given number of needles, at their proper working height, and
may be made with a lip or flange to retain the bottom of the needles in proper place.
The sections of the needle rest are connected to the cylinder by screws or bolts
passing through slots which allow of a downward movement of the sections. They
are maintained in working position by springs and when it is required to withdraw
any of the needles from action the section upon which such needles rest is drawn down
which allows the butts of the needles to fall clear of the cams. . Working in conjunc-
tion with the needle rest is a fall catch, preferably pivoted to a spring and attached
to a chain or lever the moving of which draws forward the catch and at the same
time draws down the needle rest and withdraws the needles from action. The catch
It is held
is made with a projecting nose which grips the needles above the butts.
back from the needles and clear of the cam and cam bracket when not in action by
a small spiral spring. The needle rest and catch may be moved by hand by the
operator as the narrowing is required or the movement may be automatic by a spring
catch carried round by the carriage, which will engage with a lever at each revolution.
The needles are held in position at the top of the cylinder by a ring which encircles
the cylinder fitting into an annular notch or groove cut therein, through the division

page_text: plates which separate and guide the needles. This ring is made in sections each
secured to the other by a spring joint and is fitted with three studs and three eyelets.
It is provided with a number of slots or a continuous slot on the outer rim with a long
groove passing through each. In each slot is pivoted a small cap somewhat of E shape
on a wire which passes through it and into the grooves. When a cap is raised the
empty needles under it may be passed above the action of the cams and retained in
that position by the cap engaging with then beneath the heel.
Instead of a cylindrical shell for the cylinder cams which encloses the lower part of
the cylinder, the cylinder cams are carried on a bracket screwed to the carriage with
which they rotate round the cylinder. The cam bracket and cams so arranged only
cover the needles which are in motion, the remaining needles being clear to the butts.
By this arrangement of the cams any broken or bent needle can be seen at once, and
can be removed and replaced without taking the machine to pieces, which often has to
be done with machines as at present constructed.
Two or more sets of cams may be provided for each machine according to its size,
preferably mounted on a separate bracket attached to and standing up from the
carriage. Two or more sets of cylinder cams may be applied in conjunction with the
ordinary cam shield but the use of a bracket to carry each set is much better. Where
two or more brackets are applied a small rod or bar may be used to connect them together
at the top to act as a stay or support. By this arrangement of cams two or more
courses can be knitted at the same time, and in larger machines for knitting under-
vests, jerseys, and the like, as many as five or more courses may be knitted at each
revolution of the carriage.
Each set of cylinder cams comprise an up-throw cam and a press-off cam, working
in conjunction on the butts of the needle. The up-throw cam is of A or triangular
shape and is preferably provided with two projections or wings at the heel which
prevent the needles striking the cams and the consequent breakage. The press-off
cams are preferably in contour curved at their lower ends somewhat in the form of
a J or hook and connected to the cam bracket by a pin passing through a slot
therein so that the position may be easily adjusted and fixed by a wing thumb nut on
the other side. The two J cams are preferably pivoted on one pin so that together
they form a continuous guide for the needles, preventing catching and breakage.
Instead of being of J shape the press-off cams may approach more nearly to a semi-
circular or half moon shape, elongated at their ends and similarly pivoted and adjusted
by a screw and nut.
The ribbing arm is constructed to rise perpendicularly over the centre of the
machine being cranked or bent at its lower extremity to clear the cylinder and
attached to the carriage with which it rotates. It is provided with one, two, or more
legs, according to the size of the machine, which fit into sockets provided in the
carriage. The bobbin carrier is attached to the ribbing arm and revolves with it
carrying the bobbins with it. The bobbin carrier may be otherwise attached to or
made to revolve with the carriage if desired, the bobbin carriage being placed above
the cylinder. The number of bobbins is equivalent to the number of sets of cams
and as they rotate with the carriage any entanglement or twisting of the yarns is
prevented.
The dial shaft passes up through the ribbing arin and is attached by a screw and
nut above it to a main supporting arm which is socketed at its lower end to the bed.
This arm steadies and supports both the ribbing arm and the dial shaft. The dial
shaft may be moved to adjust the position of the dial either where it connects with
the supporting arm, or it may be rigidly attached to the supporting arm and the
latter be movable in a slot in the bed to adjust the position of the dial. The dial shaft
is connected to the dial by means of an adjustable bar with two arms which is fitted
and screwed to the lugs beneath the dial. A square on the dial shaft fits into a
square hole in the adjustable arm, or they are otherwise connected to rotate together,
and any movement of the dial shaft is thus conveyed to the dial which is thereby
adjusted. By this arrangement all necessity for a movable post such as is placed
inside the cylinder of some machines is dispensed with, thereby removing any obstacle
L

page_text: which would prevent the sinking of the work at the right time and leaving the whole
inner circle of the cylinder clear without obstruction for the passage of the web as it
passes down.
The ribbing cam, shell or plate is placed on the top of the dial and is rotated by a
spring, latch, or pawl carried by the ribbing arm which engages with it and the two
are carried round together as the carriage rotates.
The rib cam, shell, or plate, is made of greater diameter than heretofore, the out
throw being much further from the dial shaft. By this arrangement is provided a
short or long out throw for a large machine which can be adjusted by the improved
cam to any length.
The rib cam is somewhat similar in shape and construction to the J cylinder cams
hereinbefore described, but the position of the different parts is reversed. The outer side
of the cam is made of a double curve pivoted at one end and adjustable by a set screw
at the other. The inner cam is pivoted at one end and jointed in the centre. the other
end carrying an adjusting pin which slides in a slot. The moving of the pin from
one end of the slot to the other brings the cam within the line within which the
needles travel and and thus throws the cam clear of action on the needles. By this
arrangement of cam and means of adjustment the throw of the needles can be set to
any required length. One, two, or more of these cams is employed according to the
number of cylinder cams applied to the machine, each set of rib cams always working
in conjunction with a corresponding set of cylinder cams. The ribbing needle is
made with the crank much nearer the point in proportion to the entire length than
has hitherto been done, and the heel or butt of the needle is elongated to pass under
the cam, plate, or shell which gives a steadiness and rigidity to it in working not
found in the ordinary needle, and also holds it more securely, thus preventing
liability to breakage and producing better and more even work.
The several cams herein described may be applied to straight machines as well as
to circular machines.
By arrangement of this invention 1 consider I can produce a more perfect web
than hitherto on a circular machine, and it also allows for the production of cardigan,
cross, ribbed, and plain patterns on the same machine.

COMPLETE SPECIFICATION.
Improvements in Knitting Machines.
I, JOHN THOMAS HARRIS of Gallowtree Gate Leicester and Tipping Street Man-
chester Maker of Knitting Machines 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 relates to circular knitting machines wherein the cams for operating
the knitting needles may be made to revolve continuously about the needie cylinder
to operate the needles to form a circular web, or may be made to reciprocate about
certain portions of the needle cylinder and needles to knit straight fabric, or to fashion
a web as in the production of heels and toes for stockings and the like.
The various improvements in the machine will be understood by the following
description in reference to the accompanying drawings in which Fig. 1 is a sectional
side elevation of a circular knitting machine containing my improvements and of part
of which
Fio is front elevation

page_text: Fig. is a front elevation of the ben crank lever for depressing certain frame
needles. Fig. 7 is a view shewing one of the frame needles and sections depressed
by the bell crank lever.
Fig. 8 is a plan of the mechanism at the top of fig. 1 for adjusting the position of
the ribbing dial.
Fig. 9 is a horizontal section on the line a. a. fig. 1.
Fig. 10 is an underside view of the ribbing dial shewing the arms L² in engage-
ment with the lugs L³.
Fig. 11 is an edge view of the cam-carrying plate O, and Fig. 12 is a transverse
section of the circular plate R' on the line bb of fig. 9.
Fig. 13 is a sectional side elevation of a larger machine, with modifications
constructed according to this invention.
Fig. 14 is a section of the ribbing dial, and
Fig. 15 is a view, one half of which shows the underside of the ribbing dial and the
other half, where part of the dial is removed, shows the ribbing cams.
Fig. 16 is an edge view of the wing U¹.
A is the bed-plate of the machine which is recessed to receive the teeth B¹ of
the carriage B and formed with two shoulders A' A² upon which the carriage rests
and revolves.
· The carriage thus fits into an annular seating formed between the upright
shoulder A3 at the outside edge of the bed and the vertical back part A*.
The carriage is held in position by a ring B² resting on its upper extremity and
secured to the vertical side A of the bed-plate by a series of screws B³.
The carriage may be rotated by means of a toothed wheel B1 gearing with the
teeth of the former and working in an opening A in the bed-plate.
The toothed driving wheel B may be operated by a crank handle or if necessary by
power.
The needle cylinder C is of increased height and is connected to a flange A on the
upper part of the bed-plate A by means of screws C¹.
The tricks or dividing plates C2 of the needle cylinder C are cut away at their
lower ends (Figs. 1 and 2) to allow of a ring D being secured to the base of the
needle cylinder C upon which the butts of the needles may rest when in their lowered
position.
The ring D. D2 D3 is preferably formed in three sections, one of which riz.: that
marked D extends round about three-fourths of the circumference and is fixed rigidly
in position by the screws D¹; the remaining two sections D2 D3 are at the front of the
needle cylinder and are adapted to be depressed for the purpose of placing the needles
below the action of the cams as hereinafter described.
Each of the two sections D2 D3 is supported and retained in its elevated or
normal position by a spring D whose lower curved part is centrally fixed to an
extension on the ring B2 by a screw 1)³.
In order to permit of the downward movement of the sections D² 1³ they are
movably secured to the needle cylinder by screws D D' Fig. 2, passing through
slots D³ D' in the sections D2 D3 the lowering of the sections is simultaneous with the
descent of the needles resting thereon.
The lower ends of the needles enter the groove or recess D formed between the
ring D and the needle cylinder (so that the needles remain vertically supported in
the needle cylinder and the butts of the needles would be clear of the operating cams
and would not therefore produce stitches.
The lowering of the sections to put the needles resting thereon out of action is
effected by means of a bell-crank lever or clutch E (figs. 1 and 7) pivotted movably
between the upper extremities of two springs or plates E secured by means of
screws E² to a horizontal extension B of the fixed ring B2 and retained in its in-
operative position by a spiral spring E³.
To the shorter arm E of the bell-crank lever E is connected a chain E' the lower
end of which is attached to another bell-crank lever E pivotted in a slot at the
interior of the bed plate A and operated by a horizontal rod E' passing through

page_text: the bed-plate and terminating in a knob E on the outside of the bed-plate as shown
clearly in fig. 1.
The lowering of the needles to place them clear of the operating cams as before
described is effected by outwardly withdrawing the knob Es which action will cause
the upper hooked end E of the lever E to move forward and engage the butts of the
needles when in their normal position and depress them and the section as shown in
Fig 7 so that they are clear of the operating cams which in said Fig. 7ª are indicated
by dotted lines.
The upper hooked end E' of the lever E fig. 7 is laterally wide enough to cover
the butts of the whole of the needles resting on the section and will retain the needles
and section in the lowered position, shown in fig. 7ª so long as the knob E8 is main-
tained in its outward position, but immediately the knob is released the spiral
spring E will cause the hook E to disengage the butts of the needles and the
section will be elevated and placed in its normal position through the influence of the
spring D.
Instead of the elevating and depressing cams for operating the frame needles
being, as heretofore, carried by and secured to the internal face of a cylindrical
shell enclosing and rotating round the needle cylinder, the cans are carried on
brackets.
F is the cam bracket which is secured to the carriage B by means of screws Fi
and revolves therewith.
The upper end of the bracket is formed with plates F having connected thereto
by the screw F³ a curved shell or frame F with recessed edges or rims to carry a
plate F' on whose inner face the operating cams are secured by preferably counter-
sunk-headed screws F6.
The number of cam brackets employed is determined according to the size of the
knitting head and the number of courses in the fabric it is desired to knit in a single
revolution of the machine.
Each cam bracket carries preferably one elevating cam G and two depressing
cams G¹.
These cams are adjustable in relation to each other in slots G2 G³ (figs. 2. 4
and 5).
The elevating or upthrowing cam G Figs. 4 and 5, is adjustable vertically in the
slot G2 and is slightly curved or rounded at the base of the incline on each of
its sides, Figs. 4 and 5, so that whether the operating cams revolve continuously
round the whole or reciprocate about a portion of the needle cylinder, the butts.
of the needles will more readily and evenly ascend the sides of the elevating
cam G and be prevented from striking the sides thereof and becoming damaged or
broken.
The elevating cam G can be removed from the cam bracket F without interfering
with the latter; this is effected by releasing the winged-nut G₁ Fig. 2, and the
elevating cam G will fall downwards of its own weight.
The depressing cams G₁ are each adjustable in the inclined slots G³ Figs. 2, 4
and 5.
In the modification Figs. 5 and 6 the operating cams are each provided with a
screwed spindle G which passes through to the exterior of the cam bracket and is
furnished with a winged-nut G by which the said cams can be secured in position.
The shape of the depressing cams may be varied in some instances so as to
approximate a semicircular or half moon shape, elongated at the outer ends and be
adjusted and fixed in position similarly to those shown in the accompanying
drawings.
Each machine may be furnished with one, two or more of these cam brackets
according to the size of the machine and the number of courses in the fabric it is
desired to knit in one revolution of the machine and each can bracket is provided
with preferably one elevating cam and two depressing cams as illustrated in Figs 4
and 5.

page_text: By carrying the operating cams on brackets as described, the working of the
machine need never be delayed more than a few minutes as in the event of any of the
cams requiring repairing or renewing they can readily be removed without necessarily
removing the can brackets whilst in some circular machines it is imperative that the
cam shell or. cylinder should be entirely detached from the machine, causing
considerable delay.
The fact also that all the frame needles except those actually under the influence of
the operating cams are exposed to the view of the operator enables him the more
readily to detect a damaged or unsuitable needle and remove and replace it without
disarranging the parts of the machine.
Reciprocating knitting as in the production of heels and toes is more rapidly
accomplished by the compactness of the elevating and depressing cams as shown in
the cam brackets before referred to, as the transit of the needles through the cams is
quicker than in ordinary machines and the distance the cams are moved round the
needle cylinder before their direction is reversed is less.
.
When two or more cam brackets are employed on one machine they may be
connected together by a rod or bar or equivalent means which will act as a stay or
support thereby keeping them firm and rigid during the revolution of the machine.
The ribbing arm H rises above the centre of the machine and encloses the dial
shaft J and is provided with one, two, or more legs or supports H' (Figs. 1 and 13),
according to the size of the machine, whose lower ends are fitted into sockets in
extension B, Figs. 1, 2 and 3, of the carriage B and revolves therewith.
The upper part of the ribbing arm H is reduced in circumference, Fig. 1, so that
one or more preferably circular bobbin-carrying plates H2 may be keyed or otherwise
supported thereon as shown in Fig. 1, the lower plate H2 is provided with a central
opening to pass down the reduced part of the ribbing arm until it rests on the thicker
lower portion; and the upper plate H³ is held between two collars H, H. The
ribbing arm H may be extended vertically to admit of any required number of
bobbin-carrying plates being fixed thereon.
The bobbins may be supported in the position shown in fig. 1 or in an inverted
position as in fig. 13; the number of bobbins employed on one machine is determined
by and is preferably similar to, the number of sets of operating cams or the number
of courses made at each revolution of the machine, except in cases where a splicing or
thickening thread is employed when one or more but not exceeding twice the number
may be used.
The bobbins may also be carried by and rotated with the cam-carrying plate T as
shown in fig. 13.
The bobbin carrier may be otherwise attached to or made to rotate with the carriage
if desired, the bobbin carriage being placed above the needle cylinder.
It will be readily understood that the fact of the yarn-carrying-bobbins being
rotated with the carriage, any tendency on the part of the thread to drag is avoided,
at the same time the thread is allowed to feed freely and uninterruptedly onto the
needles and any twisting or entanglement of the yarns such as occurs in ordinary
machines where the bobbin is stationary is prevented.
The dial shaft J passes up through the interior of the ribbing arm H and terminates
in a screw-threaded end by which and a nut J₁ fitting thereon the dial shaft is
secured to a rigid supporting arm K the lower end of which is socketed or otherwise
suitably connected to the bed-plate B.
The arm K steadies and supports the dial shaft J and the ribbing arm H and
prevents vibration or oscillation of same when the machine is in motion.
In figs. 1 and 13 the supporting arm K is shown with one leg, but there may be
two or more legs according to the size of the machine, each fitted in the bed-plate
and forming an arch or otherwise terminating in one common upper end through
which the dial shaft passes.
The lower end of the dial shaft J passes through the ribbing dial L and is squared
to fit into a square hole in the boss L' carrying the radiating arms L³ the ends of

page_text: which are ätted between the lugs L³ so that any movement of the dial shaft is com-
municated to the ribbing dial.
The boss of the radiating arms L is rigidly secured against the ribbing
dial by means of the nut L fitted on the screw-threaded lower end of the dial
shaft.
By this arrangement the necessity for a vertical movable post in the interior of
the needle cylinder as in some machines is dispensed with and the knitted web
is allowed to pass freely down inside the needle cylinder without encountering any
obstacles.
The dial shaft J may be turned to shog or adjust the ribbing dial L so that
the ribbing needles intercalate between the next adjacent or any other frame
needles.
The shifting of the dial plate L, as mentioned, enables me to produce shogged
ribbed fabric in various patterns.
The shogging or moving of the ribbing dial L is effected by the operator partly
rotating the dial shaft J by means of the vertical handle M' on the upper face
of the toothed quadrant M (figs. 1 and 8) mounted on a square on the dial
shaft.
When the dial shaft J is in its normal position, the teeth of the quadrant M engage
the teeth of a horizontal spring controlled detent plate or bar N in a groove or
slot K' in the upper end of the supporting arm K and is retained in proper, working
position by the slotted horizontal plate N₁ screwed or otherwise fixed over the top of
same.
The horizontal toothed plate N is adjusted and secured in position by the
tightening of the thumb screw N2 which passes through the slot K and into the
former.
.
When it is desired to shog the ribbing dial as before mentioned the ribbing needles
are withdrawn from intercalation between the frame needles and the toothed plate N
is moved out of engagement with the toothed quadrant M and by taking hold of the
handle Mand moving it to the right or left a similar movement is conveyed to the
dial L.
The vertical adjustment of the ribbing dial L is effected by means of the lever M²
Fig. 13, fulcrummed between lugs K2 on the upper end of the supporting arm K the
inner end of the said lever M2 is slotted or forked to engage the upper end of the dial
shaft J and is rigidly secured thereto by the nut J'.
The outward end of the lever M2 is in the form of a handle M³ which on being
depressed by the operator elevates the dial shaft J and with it the ribbing dial L,
they may then be secured in position by a pin or screwbolt and nut M passing
through a slot M in the lever M² and through one of the holes M in the vertical
bar M secured at its lower end to the side of the supporting arm K; or the lever M²
may be retained in position by other suitable means.
The supporting arm K (fig. 13) is constructed in preferably two parts, so that
when for any reason it is desired to disconnect the mechanisin attached to the upper
part of the arm K it can be effected by depressing the handle M³ and withdrawing
the screw-bolt K3; the upper part of the arm K can then be partly rotated and the
attached mechanism moved away from the centre of the machine.
In some instances I may prefer to connect the dial shaft J and the supporting
arm K rigidly together, by squaring the upper end of the dial shaft to fit into a
square opening in the supporting arm; in such cases the shogging or moving of the
ribbing dial would be effected by making the lower end of the supporting arm
movable in a slot in the bed.
The irregular-shaped plate or shell O is placed above the ribbing dial L and is
furnished at each corner with a lug 01 (figs. 9 and 11) to which are connected by
small thumb screws 02 or equivalent means, the knocking over cams P adjustable in
the slots O in the lugs 01.
The outthrow cams R are also connected to the under surface of the plate Ỏ and

page_text: are adjustable for the purpose of increasing or decreasing the outward movement of
the ribbing needles by means of the screwed stud R' passing through the slot O* in
the plate and held in position by the winged nut R2.
The outthrow cams R rest in a groove R³ fig. 12 formed across the upper face of
the circular plate R', the sides R' of the said groove act as a guide to the outthrow
cams R when they are moved either inwards or outwards.
The inner end of each of the outthrow cams R is formed with a semicircular
recess Re so that when the two cams are moved into their innermost position they
may encircle the boss R7 of the circular plate R'.
The bottom of the circular plate R4 is let into and revolves in a recess in the
ribbing dial L.
The ribbing cans are rotated by an upright bolt S (fig. 1) passing through the
ribbing arm H and connected at its lower end to a horizontal plate S₁ screwed to the
upper surface of the cam-carrying plate O or by means of a vertical rod S² (fig. 13)
the lower end of which is fitted into a boss or socket S³ on the cam-carrying plate T,
the upper end passing through an opening in the ribbing arm H'.
In Figure 15 the ribbing cam shell or plate T is shewn of larger diameter than
usual thereby enabling it to carry a number of sets of ribbing cans which working
in conjunction with a corresponding number of sets of frame cylinder cams will enable
a similar number of courses of ribbed fabric to be produced at each revolution of the
machine.
The outthrow cams T4 are much farther from the dial shaft than in ordinary
machines and are adjustable as regards increasing or diminishing the outward move-
ment of the ribbing needles in recesses T in the shaped plate T2, the extent of the
adjustment of the outthrow cams is determined by the slots T³ in the ribbing cam-
plate T.
The cams are clamped in position by thumb screws or their equivalent on the upper
face of the plate T.
The knocking over cams U are fixed in the outwardly extending parts T' of the
plate T and their outward ends pass underneath and are held in position by a clamp-
wing-plate U.
The knocking over cams are adjustable in the slots U2 and are fixed in position by
a thumb-screw connected to same and tightened against the upper surface of the
cam-carrying plate T.
The ribbing needles used in such a ribbing dial as is shown in fig. 13 are made with
the butt or cramp much nearer the hook in proportion to the entire length than is
usually the case, and the hinder part is elongated to pass under the circular plate
which imparts a steadiness to the moving of the needles thus diminishing the liability
to breakage and producing more even work.
By means of the improved ribbing dial as before described I am enabled by placing
certain sets of cams out of action to produce various kinds of ribbed fabric.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what I
