Improvements in Rotary or Flat-bar Knitting Machines.
I, CHARLES HENRY ALDRIDGE, of Pinfold Gate, Loughboro', in the County of
Leicester, Hosiery Machinist, do hereby declare the nature of this invention to be
as follows:
The object of this invention is to effect certain improvements in rotary or flat
bar knitting machines of the type known as "Cotton's Patents," and where the
needles are not fast to the needle bar, but are attached to sliding jacks which
slide in tricks, grooves, or combs, cut in or attached to, or forming part of the
needle bar, so that when the said jacks, are in their top position, the needle or
needles attached thereto are in action and when in their bottom position, the needles
will be out of action. The said jacks (and consequently the needles also) are
selected by a jacquard cylinder, or other jacquard appliance.
The first part of my invention, consists of an improved method of attaching
the needles to the sliding jacks. Instead of soldering or brazing the needles to the
jacks, as is commonly done, I fashion and arrange a suitable mould, so shaped
as to form a space wherein to receive the needle, or needles and also the end of
the jack or slide, to which it is desired it, or they should be attached. The end
of the jack to which the needle or needles are to be attached, is suitably shaped
so as to leave a space about the stems of the needles, a mixture of lead and tin,
or other suitable alloy is then poured into the space formed in the mould around
the needle stems, and the end of the jack whereby the needle or needles, and jack
are firmly and truly cast, or fixed together in the desired relative position.
When grooves or tricks are cut in the needle bar to receive the needle jacks, I
arrange a suitably shaped bar (preferably made of steel) which may be fastened
to the edge or other convenient part of the needle bar in such a position, that one
part of the said bar shall cover or partly cover the top ends of the grooves, or
tricks in the needle bar. The needle jacks are so shaped, that when in their top
position the tops of the jacks, or shoulders formed on the sides thereof, shall be
drawn up to or rest against the said bar, whereby the heads of the needles are all
drawn into a correct line for "knocking over
"the loops.
In order to prevent those needle jacks from rising which are selected by the
jacquard appliance, to remain out of action, when the needle bar rises, I arrange
a suitably shaped bar, which carries a row of springs (one to each jack). The
said springs may have a V shaped or knuckle shaped end, which rests upon the
edge of the jack. At a suitable position on the edge of the jack, I cut a V shaped
recess or nick, into which the end of the said springs fall, when the jacks are in
their lowest position. The springs thus afford sufficient resistance, to the friction
of the jacks in the grooves or tricks in the needle bar to hold all the jacks down
when the needle bar rises, excepting those jacks which are caught by the droppers
or catches, (which are governed and selected by the jacquard appliance) in which
case the said selected jacks are drawn upwards while those which are not required

page_text: to come into action are held down by the said springs as described. The said
spring bar may be stationary, or in some cases it may receive a to and fro move-
ment, governed by the needle bar or by other and independent means, but the bar
is not allowed to rise and fall with the needle bar. The said spring bar may be
carried by suitable brackets and provided with screw adjustment, so as to regulate
the height of the springs, according to the depth of "sinking" or length of loops
to be knocked over.
"
In some cases, where some needles are in action, for one or more consecutive
courses, and then other needles for other courses, and so on as selected by the
jacquard appliance it is desirable, in order to make a good selvedge, that the outside
or selvedge needles should come regularly into action, at regular predetermined
courses, independent of the selection made by the jacquard appliance for forming
the desired pattern. To do this, I arrange and form a double catch upon the
needle jacks, one catch to engage with a catch or nose on the dropper, (which is
selected by the jacquard appliance), and the other catch to engage with what I
will call the selvedge needle lifter, as hereinafter described. I also arrange and
form a double catch or nose upon the dropper, one to engage with the needle jack
and the other to engage with the selvedge needle lifter. To a convenient part
of the needle bar I attach a light rocking shaft. This shaft may carry suitable
brackets, which in turn carry two sliding bars. These sliding bars may be
attached, to the screw boxes, or fashioning screws at the ends of the frame,
so that when "fashioning" and the screw boxes are racked to alter the width
of the work, the said sliding bars are shifted also. To each of the said sliding
bars, suitable brackets are attached, these brackets carry the selvedge needle
lifters and are so arranged as to keep them in front of the selvedge needle jacks,
which position is maintained by means of the said sliding bars being attached
to or governed by the fashioning screws as herein before described The selvedge
needle-lifters are formed with two catches or noses, one to engage with the needle
jack, and one to engage with the dropper. The several parts herein before described
are so arranged and adjusted, that when the herein before mentioned rocking shaft
is turned or rocked in one direction, the selvedge needle lifters will engage with
the corresponding catches or noses upon the needle jacks, so that as the needle
bar rises, the selvedge needles rise also, and when the said rocking shaft is rocked
or turned in the other direction, the selvedge needle lifters engage with the
catches or noses of the droppers, and thereby hold the droppers out of action.
Thus by the rocking of the said shaft and the parts attached thereto, the selvedge
needles may be thrown in or out of action as desired, independent of the jacquard
appliance. The movements of the said rocking shaft may be effected and
governed, by a cam or other well understood and convenient appliance.
In some cases, as for instance when making hose, with plain heels, it is desirable
that all the needles upon which the heel pieces are formed, shall be brought in
action together at certain predetermined courses, while those needles which form
the instep, shall continue to be under the control of the jacquard appliance. To
do this I arrange a bar, carried by suitable brackets, which I will call the heeling
bar, in a convenient position, preferably at the back of and below the needle bar.
To this heeling bar I attach suitable adjustable brackets, so arranged and of
such a width, as to come below all the needle jacks which are required in action
to form the heel pieces, so that when the heeling bar is lifted all the heeling
needles will be lifted also, and thereby brought into action. The lifting of the
heeling bar may be effected by means of suitable cams, and levers, and the said
cams may be caused to lift the heeling bar when and how desired, by means of
shogging trucks, or rollers running thereon, which may be moved by levers, and
governed by a chain, provided with suitable notches or inclines, or by other
convenient means. It will be understood that when this heeling bar is in action
for forming plain heels, the jacquard appliance must cease to control the heeling
needles altogether. To do this I prolong the tails of the droppers to a convenient

page_text: length. Below these tails I arrange a light shaft. Upon this shaft I arrange
suitable cams or lifters, so formed and arranged, that when the said shaft is turned
into one position, the said cams engage with the tails of the droppers which would
act upon the heeling needles, and hold them out of action, and when turned into
another position, all the droppers are left in action.
Thus the droppers which lift the heeling needles when under the control of the
jacquard appliance, are thrown out of action, and the whole of the heeling needles
may be brought into action, together at certain predetermined courses, as herein-
before described.
"
In some cases I arrange the jacquard cylinders or the card cylinders, quite
independent of the rising and falling movements of the needle bar. In this case
all the card cylinders may be carried by or upon one shaft running through all
the divisions of the frame. This cylinder shaft may be carried by arms which in
turn are carried by another shaft which may be free to rock in bearings situated
below the cylinder shaft, or in other convenient position. To this shaft a rocking
movement may be imparted by cams and levers, or other convenient means, so
that during the to and fro "knocking over movements of the needle bar, while
the dropper tails or pins in the dropper tails, are in contact with the cards or
cylinders, the cards or cylinders shall follow the said to and fro movements, and
so leave the droppers quite free in their movements during their time of selection.
In some cases it is desirable that a pattern shall be produced which shall
consist of two or more distinct designs. For example in a hose one or more designs
may be used to form a heading and another design, which may be continually
repeated may be used to form the leg of the hose or body of the pattern. To do
this by simply bringing fresh cards into action, for each course of work a very
large number of cards would be required, but my invention enables a band of
cards to be so arranged and used that one portion of the band of cards shall come
into action once, each card in consecutive order. The remaining portion of the
band of cards can be repeated as many times as desired. This I effect as follows:-
Taking for instance a band of cards for forming a heading followed by a pattern
or design that is required to be repeated. During the formation of the heading
the band of cards is advanced one card at a time and each card comes into action
in consecutive order. Then when the heading is completed the cylinder shaft
is racked twice between each selection of needles, so that every second card comes
into action. Then when a certain portion of the band of cards is reached their
movement is reversed and the cards which were passed over as the band of cards
advanced, are brought into action as they return. For example;
If the number of cards necessary to form a certain pattern be eight, then I
arrange and lace them up as follows:-1, 8, 2, 7, 3, 6, 4, 5. After No. 1 has
been in action the card cylinder shaft is racked forward twice. This brings
No. 2 into action. Again it is racked twice, when No. 3 comes into action, and
again so for No. 4. Then it is only racked once, which brings No. 5 into action.
Then the movement of the band of cards is reversed, and racked back twice. This
brings No. 6 into action, and so on for Nos. 7 and 8, when it is again racked only
once, which brings No. 1 into action again. This completes the cycle of move-
ments. The movement of the band of cards is again reversed, and these
movements and reversings are continued for as long as desired. These movements
of the band of cards I effect as follows:-Two ratchets are so arranged, as to act
upon two ratchet wheels. One ratchet wheel is fast to the cylinder shaft, and the
second ratchet wheel works upon a stud, and is geared to the cylinder shaft by a
pair of gear wheels, so that when one ratchet is in action the cylinder shaft is
rotated in one direction, and when the other ratchet is in action, the shaft is
rotated in the opposite direction. The two ratchets are provided with suitably
shaped tails which are acted upon by small cams carried by a light shaft in such
a manner that when the said light shaft is turned into one position one ratchet
will be in action, and when turned into another position the other ratchet will

page_text: be in action. A suitable chain is caused to move one or more links, with each
movement of the band of cards. This chain is provided with suitable notches
or inclines, which come into action at the time it is desired to change the move-
ment of the band of cards, the said notches or inclines lift certain levers which
throw into action a ratchet which acts upon a ratchet-wheel, which is fast to the
aforesaid light shaft, by which means the light shaft is turned and one ratchet
is brought into action, and the other thrown out of action as hereinbefore
described, and the movement of the band of cards is thereby reversed.
The two ratchets may be worked by one cam, which imparts to them a double
movement, between each selection of needles, but during the time that the band
of cards is required to advance, one card only at a time (i.e. during the formation
of a heading for instance as herein before described) the advancing ratchet
although having two movements only racks the card cylinder shaft at one move-
ment, an independent cam acts upon the tail of the said ratchet, and holds it out
of action at each alternate movement.
Then when the repeating portion of the band of cards is reached, this last named
cam is automatically thrown out of action, and the ratchet then acts twice between
each selection of needles as hereinbefore described.
When a large number of cards are required to form a pattern or series of
patterns, it is sometimes desirable that they should lie together in a heap, or in
folds so as to occupy as little room as possible, while out of action, and the
space
available for this purpose, is not always in the immediate vicinity of their position
when in action. In order to convey them to and from their storage place and their
acting position, I arrange two sets of auxiliary card cylinders in a convenient
position near, the place of storage. The band of cards passes over one cylinder
on its way to action, and over the other on its way back to the place storage.
The rotation of the ordinary card cylinder, which presents the cards when in
action, will draw the cards from their resting place and I cause the auxiliary
cylinders to draw them back again. But as the band of cards may sometimes
move in one direction, and sometimes in the other, as hereinbefore described, it
will be seen that each of the auxiliary card cylinders must in turn draw the cards
back to their resting place or place of storage. This I effect as follows:-Each
of the shafts which carry the auxiliary card cylinders, are provided with a sliding
gear wheel or equivalent, which may slide upon a feather in the said shaft.
Each of these sliding gear wheels may engage with a third gear wheel, which
may be carried by and work upon a stud. This wheel I will call the stud wheel.
This stud wheel is attached to a pulley around which a card is passed, one end
of the cord is made fast to the pulley, and to the other or free end is attached a
weight or equivalent. This weight always tends to turn the stud wheel in one
direction, so that whichever sliding gear wheel is in gear with the stud wheel,
the coresponding auxiliary card cylinder will be turned by the action of the said
weight and the slack cards will thereby be drawn into their place of storage.
66
The same mechanism which reverses the band of cards, may also govern the
sliding gear wheels throwing them in and out of gear with the stud wheel as
required.
The weight may be kept wound up by means of a second cord, one end of which
may be attached to the said pulley, and the other end to a lever, worked by a cam
or equivalent.

page_text: . I, CHARLES HENRY ALDRIDGE, of Pinfold Gate, Loughborough, in the County
of Leicester, Hosiery Machinist, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
-
The object of this invention is to effect certain improvements in rotary or flat-
bar knitting machines of the type known as "Cotton's Patents," and where the
needles are not fast to the needle bar, but are attached to sliding jacks which
slide in tricks, grooves or combs, cut in or attached to, or forming part of the
needle bar, so that when the said jacks are in their top position the needle or
needles attached thereto are in action, and when in their bottom position, the needles
will be out of action. The said jacks (and consequently the needles also) are
selected by a jacquard cylinder or other jacquard appliance.
My improvements are illustrated in the drawings annexed.
In Figures 1 and 2 Sheets 1 and 2 of these drawings only so much of a
"Cotton's" knitting machine is shown, as will explain the several improvements
hereinafter described other parts not shown, being the same as (or similar to)
those usually found in this well known type of knitting machine.
Figure 1 is a general section of the chief-working parts of such a machine,
with some adjacent parts, and Figure 2 Sheet 2 is a part front view of the same.
A are the needles, B are the sinkers, and 13¹ are the knocking over bits. A¹ is
the needle bar, which is connected by joints A³ to the arms A3 which are carried
by the shaft A which is the well understood needle bar shaft, and which receives
its motion from the cam shaft, whereby the needle bar is caused to rise and fall
as desired, also attached to the needle bar A¹ is the usual bracket or arm (not
shown) and handle through which the needle bar receives its "pressing" move-
ments, all these parts working in the usual well understood manner.
A5 is a sliding jack to which a needle (or needles) A is attached, by means
hereinafter described. The jacks A5 slide in grooves cut or otherwise formed
in the face of the needle bar A₁ and they are retained in these grooves partly
by means of the cap or cover plate A16 (which is fast to the needle bar A) and
partly by means of springs hereinafter described.
The sliding jack A5 is so arranged and controlled, that when in its raised
or top position its needles or needle A will be in action, and when in its bottom
or lower position they will be out of action.
A. bar C Figures 1 and 2 is carried by brackets C¹ Figure 2 which are fast to
the needle bar A¹. This bar C has a comb C2 cut or otherwise formed upon its
under surface through suitable holes, in this comb a rod C³ passes, a second
comb C may be similarly formed upon the front edge of the said bar and a third
comb C³ may be carried at a convenient distance below the bar C by suitable
brackets. Centered upon the rod C³ are a number of droppers E one to each
jack A5. These droppers work between and are guided by the three said
combs C² C and C. The lower end of each dropper E is so shaped at E³ as to
engage with the catch A upon the jack A5 (see Figure 3) and when these (the
jack A5 and the dropper E) are locked together as shown in Figure 1, the jack
and consequently its corresponding needle or needles are locked to the needle
bar A and will rise and fall therewith in the usual well understood manner.
D (see Figure 1) is a shaft carried by the brackets C (which are fast to the
needle bar A¹). To this shaft D arms D' are fast. These arms carry a shaft D³
and upon this shaft is a square cylinder D³, around this cylinder a band of cards

page_text: passes, as is indicated by the dotted lines D. Upon the under side at the front
end of each dropper E is a pin E which is so arranged as to engage with one of
the cards of the band of cards D'. These pins may be arranged so as to stand
in two or more rows. The cards are perforated in the usual well understood
manner of jacquard" cards. The card cylinder 13 (and consequently the card
that is in action also) is caused to move to and from the dropper pins E2 by means
of the rod or link I which is acted upon by suitable lever and cam or cams, so
that where there is a hole in the card under any particular dropper pin E³, that
dropper will remain locked to the jack A as shown in Figure 1 but where there
is no hole in the card under a dropper pin E2 that dropper is turned upon the
rod C3 and is thereby disengaged from the jack A, and that jack is consequently
not lifted when the needle bar rises, and so the corresponding needle or needles
do not receive a fresh loop. The card cylinder shaft 12 is rotated by means of
suitable cam or cams through the ratchet D which acts upon a suitable ratchet
wheel, which is fast to the cylinder shaft D2, and this shaft D2 may be held in
each of its four positions, by means of a suitable retaining spring, which will be
well understood.
In some cases instead of using a band of cards as herein before described, a
jacquard barrel, drum or cylinder, of any of the several well known types may
be used.
Having described the general arrangement of some of the chief parts of the
machine, I will now describe the details more fully.
The first part of my invention consists of an improved method of attaching
the needles to the sliding jacks. Instead of soldering or brazing the needles to the
jacks as is commonly done, I fashion and arrange a suitable mould so shaped
as to form a space wherein to receive the needle or needles and also the end of the
jack or slide, to which it is desired it or they should be attached.
The end of the jack to which the needle or needles are to be attached is suitably
shaped so as to leave a space about the stems of the needles, a mixture of lead
and tin, or other suitable alloy, is then poured into the space formed in the
mould around the needle stems and the end of the jack, whereby the end of
the needle or needles and jack are firmly and truly cast or fixed together in the
desired relative position. This will be understood by referring to Figures 3, 4
and 5 Sheet 1.
Figure 3 is a side view and Figure 4 is an edge view of a jack A5 with two
needles A attached thereto, and Figure 5 shows the needles and top end of the
jack in their relative positions before they are cast together. The cross lined
part A7 indicates the metal that is cast around the needle stem and into the recess
of the jack as indicated, thereby effectually fastening the needle or needles to
the jack.
I
When grooves or tricks are cut in the needle bar, to receive the needle jacks
arrange a suitably shaped bar (preferably made of steel) which may be fastened
to the edge or other convenient part of the needle bar, in such a position, that
one part of the said bar, shall cover or partly cover the top ends of the grooves
or tricks in the needle bar. The needle jacks are so shaped, that when in their
top position the tops of the jacks or shoulders formed on the sides thereof shall
be drawn up to or rest against the said bar, whereby the heads of the needles,
are all drawn into a correct line for "knocking over the loops.
This bar A8 is shown in section fast to the top of the needle bar, in Figure 1
and it will be seen that the front edge of it covers or overhangs part of the trick
or groove in the needle bar A' in which the jack A5 slides. The jack A5 has a
set off," or shoulder A³ Figures 3 and 5, which strikes and rests against the
bar A8 when the needles are in action, thereby keeping all the needles level at the
head when they are "knocking over their loops.
66
In order to prevent those needle jacks from rising which are selected by the
jacquard appliance to remain out of action when the needle bar rises, I arrange

page_text: a suitably shaped bar which carries a row of springs (one to each jack). The
said springs may have a ✓ shaped or knuckle shaped end which rests upon the
edge of the jack. At a suitable position on the edge of the jack I cut a V shaped
recess or nick into which the end of the said springs fall when the jacks are in
their lowest position. The springs thus afford sufficient resistance to the friction
of the jacks in the grooves or tricks in the needle bar, to hold all the jacks down
when the needle bar rises, excepting those jacks which are caught by the droppers
or catches (which are governed and selected by the jacquard appliance) in which
case the said selected jacks are drawn upwards, while those which are not required
to come into action are held down by the said springs as described.
The said spring bar may be stationary or in some cases it may receive a to and
fro movement, governed by the needle bar or by other and independent means,
but the bar is not allowed to rise and fall with the needle bar. The said spring
bar may be carried by suitable brackets, and provided with screw adjustment,
so as to regulate the height of the springs, according to the depth of "sinking
or length of loops to be knocked over.
"
F is the spring bar which may be fast to suitable brackets F2. This bar has
a ledge or shoulder F3 upon which the lower ends of all the jacks A5 rest when
the needle bar is in its lowest position. F4 are springs one to each jack A³.
These springs may be cast in "leads" as shown at F5 and fast to the bar F.
These springs are so shaped and arranged, that when the needle bar A¹ is in its
lowest position, the bent or knuckle ends of the springs, engage with the V shaped
nicks A in the needle jacks A5 so that when the needle bar rises, those jacks
which are not caught by the droppers E are held down thereby, and so their
needles do not receive fresh loops. As will be seen this bar F can be made to
slide up and down in grooves and be set higher or lower by set screws.
some cases instead of the spring bar F being fast to the bracket F2 as hereinbefore
described, it may have a to and fro movement imparted to it by cams and levers
so as to follow the to and fro movement of the needle bar.
In
In some cases, where some needles are in action for one or more consecutive
courses and then other needles for other courses, and so on as selected by the
jacquard appliance, it is desirable in order to make a good selvedge, that the out-
side or selvedge needles should come regularly into action at regular pre-deter-
mined courses, independent of the selection made by the jacquard appliance for
forming the desired pattern.
To do this I arrange and form a double catch upon the needle jacks, one catch
to engage with a catch or nose on the dropper (which is selected by the jacquard
appliance) and the other catch to engage with what I will call the selvedge-
needle-lifter as hereinafter described. I also arrange and form a double catch
or nose upon the dropper, one to engage with the needle jack, and the other
to engage with the selvedge-needle-lifter. To a convenient part of the needle
bar, I attach a light rocking shaft. This shaft may carry suitable brackets,
which in turn carry two sliding bars. These sliding bars may be attached to
the "screw-boxes," or fashioning screws, at the ends of the frame, so that when
fashioning," and the screw boxes are racked to alter the width of the work the
said sliding bars are shifted also.
To each of the said sliding bars, suitable brackets are attached. These brackets
carry the selvedge needle lifters, and are so arranged as to keep them in front of
the selvedge needle jacks which position is maintained by means of the said
sliding bars being attached to or governed by the fashioning screws, as herein-
before described. The selvedge-needle-lifters are formed with two catches or noses,
one to engage with the needle jack, and one to engage with the dropper.
The several parts herein before described are so arranged and adjusted, that
when the herein-before mentioned rocking shaft is turned or rocked in one direction,
the selvedge-needle-lifters, will engage with the corresponding catches or noses
upon the needle jacks, so that as the needle bar rises, the selvedge needles rise

page_text: also, and when the said rocking shaft is rocked or turned in the other direction
the selvedge-needle-lifters engage with the catches or noses of the droppers and
thereby hold the droppers out of action.
Thus by the rocking of the said shaft and the parts attached thereto, the
selvedge needles may be thrown in or out of action as desired, independent of
the jacquard appliance. The movements of the said rocking shaft may be affected
and governed by a cam or other well understood and convenient appliance.
This arrangement will be understood by referring to Figures 1 and 2 Sheets 1
and 2. It will be seen that the needle jack A5 has a double catch formed
thereon A A Figure 3 Sheet 1. The catch A6 to engage with the catch E3 of the
dropper E as herein before described, and the catch A" to engage with the
selvedge-needle-lifter G Figure 1. This has also a second catch G₁ which engages
with the catch E of the dropper E. A light shaft G3 Figure 1 is carried by
suitable bearings or brackets, fast to the needle bar A. This shaft G³ carries
brackets Gin which two bars G5 G6 can slide endwise. The selvedge needle
lifters are attached to these two bars, the lifter for the left hand selvedge
needle jack being fast to one bar, and that for the right hand selvedge needle jack
to the other bar. The selvedge needle lifters are of such a width as to cover one
or more jacks at a time. G7 G8 are two light rods or shafts reaching from end
to end of the machine, and are carried by suitable fixed bearings, and are free
to slide therein.
One rod is attached to the fashioning screw box at one end of the machine, and
the other rod is similarly attached to the fashioning screw box at the other end
of the machine. Fast to the rod G7 is an upright bracket G. A fork bracket G10
embraces the bracket G9 and is fast to the rod or bar G, so that as the needle
bar A rises and falls the fork bracket Go slides upon the bracket G. Then if
the rod G7 be attached to the right hand fashioning screw box, the right hand
selvedge lifter G G will be attached to the rod G5 or to a bracket fast thereto.
Thus it will be seen, that as the right hand fashioning screw box is racked in
or out, the right hand selvedge needle lifter, will be racked in or out also, and so
always maintain its correct position, in front of the selvedge needle jack, whatever
the width of the fabric may be.
In a similar manner the rod Ga may be attached to the left hand fashioning
screw box, and to the rod G6 to which the left hand selvedge needle lifter is
attached.
Now it will be seen that when the selvedge needle lifters are in the position
shown in Figure 1 that the catch G of the selvedge needle lifter is engaged
with the catch A" of the needle jack A5, so that whether the selvedge needle
dropper be in contact with the needle jack as shown or whether it be lifted out
of contact with the jack (by the cards acting upon the pin E2) in either case the
selvedge needle jack (and consequently its needle or needles also) will rise with
the needle bar, and so ensure a loop being taken by the selvedge needle.
If the shaft G³ be slightly turned in the direction of the arrow, the end G¹ of
the selvedge needle lifter, will press upon the end E4 of the dropper E and will
draw the catch E³ clear of the catch A6 of the needle jack, and at the same time
the catch G is turned clear of the catch A", and thus when the needle bar rises,
the selvedge needle jack will not rise with it.
Thus it will be seen, that quite independently of the selection made by the
cards, by slightly rocking the shaft G³, the selvedge needles can be caused to rise
into action or remain out of action as desired.
The rocking of the shaft G3 may be effected as follows:-The shaft is retained
in the position shown in Figure 1 by a spring (not shown) the spring tending
to keep the stop screw G in the bracket G against the needle bar. An arm Gis
may be fast to the shaft G³ a shaft G12 may be carried by suitable bearings, from
any convenient part of the framing of the machine. To this shaft an arm G¹³
is fast. This arm engages with the arm G18 on the shaft G³. Thus by applying

page_text: a suitable rocking motion to the shaft G12 the shaft G³ may be rocked also whereby
the selvedge needles may be brought into or thrown out of action as desired. The
shaft G may be caused to rock when desired by means of a cam and lever,
which may be thrown in and out of action at alternate courses or in other order
desired, by direct connection to the draw cam slide, or by any well understood
independent mechanism suitable for the purpose.
64
"
In the above description of mechanism the needles at all the selvedges are
supposed to be either in action or out of action together but it is possible that in
some cases it might be desirable, that the right hand selvedge needle should be
in action and the left hand selvedge needle out of action, at one and the same
time. In such a case two shafts similar to G³ may be used, the one shaft con-
trolling the right hand selvedge needle lifter, and the other shaft controlling
the left hand selvedge needle lifter. Thus either selvedge needle can be thrown
into or out of action independently of the other.
In some cases as for instance when making hose with plain heels, it is desirable
that all the needles upon which the heel pieces are formed shall be brought into
action together, at certain predetermined courses, while those needles which form
the instep" shall continue to be under the control of the jacquard appliance.
To do this I arrange a bar, carried by suitable brackets, which I will call the
heeling bar, in a convenient position preferably at the back of and below the
needle bar. To this heeling bar I attach suitable adjustable brackets, so arranged
and of such a width, as to come below all the needle jacks, which are required
in action, to form the heel pieces, so that when the heeling bar is lifted, all the
heeling needles will be lifted also, and thereby brought into action.
The lifting of the heeling bar may be effected by means of suitable cams and
levers, and the said cams may be caused to lift the heeling bar, when and how
desired, by means of shogging trucks or rollers running thereon, which may be
moved by levers and governed by a chain, provided with suitable studs or inclines,
or by other convenient means.
It will be understood that when this heeling bar is in action for forming plain
heels, the jacquard appliance must cease to control the heeling needles altogether.
To do this I prolong the tails of the droppers to a convenient length. Below
these tails I arrange a light shaft. Upon this shaft I arrange suitable cams or
lifters so formed and arranged that when the said shaft is turned into one position,
the said cams engage with the tails, of the droppers which would act upon the
heeling needles, and hold them out of action, and when turned into another
position all the droppers are left in action. Thus the droppers which lift the
heeling needles when under the control of the jacquard appliance are thrown
out of action, and the whole of the heeling needles may be brought into action
together at certain predetermined courses as herein before described.
Figures 1 and 2 Sheets 1 and 2 show this arrangement. H is the heeling bar
which may be guided at each end by suitable slots or bearings, in the brackets F³.
Suitable joints or brackets H' are attached to this bar, connecting rods or links H²
connect these brackets with the arms H³ which are fast to the shaft H. By
rocking the shaft H the heeling bar H may be caused to rise and fall. To the
heeling bar H brackets H5 H5 are attached. The top ends of these brackets pass
close behind the bar F and immediately below the lower ends of the needlo
jacks A5. The top ends of the brackets H5 are of such a width as to cover all the
needle jacks which are required in action, to form the heels.
Thus when the heeling bar H is caused to rise by the rocking motion of the
shaft Hall the needles immediately above the brackets H H are brought into
action. It will be understood that when this heeling bar is in action for making
plain heels, the jacquard appliance must cease to control the heeling needles
altogether. To do this I extend the droppers E to form a tail or finger E³. Below
this is a light shaft J carried in suitable bearings or brackets, which are fast
to the needle bar. Upon this shaft suitable cams or brackets J¹ are fast. These

page_text: 1
cams or brackets are of such a width, that they just cover all the droppers, that
would act upon the heeling needles. When the shaft J and the cams or brackets J¹
fast thereon are in the position shown in full lines, then all the droppers will
be under the control of the cards, but if the shaft J be turned, so that the cams
or brackets, are brought into the position indicated by dotted lines, then the
droppers covered by the cams or brackets J will be lifted into the position
indicated by dotted lines and will consequently not act upon their corresponding
needle jacks, while those droppers not covered by these cams or brackets are still
under the control of the jacquard mechanism, and control the needle jacks which
carry the needles used in the formation of the instep.
"
studs or
The shaft H is caused to rock, (and consequently the bar H to rise) by means
of suitable levers and cams as will be well understood. The trucks or rollers
which run. upon these cams may be caused to "shog" or shift into or out of the path
of the cam, (so as to bring the heeling brackets H5 into or out of action to lift the
needles at any desired course) in regular predetermined order (generally every
other course) by a pattern wheel or an endless chain provided with
inclines, or by any other of the many arrangements of mechanisms suitable for
the purpose, which are well understood by all conversant with knitting machinery.
Thus it will be seen that while the card cylinder or band of cards may continue
in action the heeling needles may be thrown into or out of action as desired thus
making fancy work all down the leg and instep and at the same time making
plain wrought heels.
•
In some cases I arrange the jacquard cylinders or the card cylinders quite
independent of the rising and falling movements of the needle bar. In this case
all the card cylinders may be carried by or upon one shaft, running through all
the divisions of the frame. This cylinder shaft may be carried by arms, which
in turn are carried by another shaft, which may be free to rock in bearings,
situated below the cylinder shaft or in other convenient position. To this shaft
a rocking movement may be imparted, by cams or levers or other convenient
means, so that during the to and fro "knocking over" movements of the needle
bar, while the dropper tails, or pins in the dropper tails, are in contact with the
cards or cylinders, the cards or cylinders shall follow the said to and fro move-
ments, and so leave the droppers quite free in their movements during their
time of selection.
Figure 6 Sheet 3 shows this arrangement. The cylinder shaft D2 is carried
by suitable arms D7 which are fast to the shaft Ds. This shaft may be carried
in suitable bearings, which may be attached to any convenient part of the frame.
A slight rocking motion may be given to this shaft by suitable cams and levers,
and the cylinder shaft D2 may be so set and located that when the needle bar
descends the pins E³ upon the droppers E will enter the holes in the cards or card
cylinder and thus the selection will be made. The rocking motion imparted to
the shaft Ds is such as to cause the cards or cylinder to follow the to and fro
knocking over movements of the needle bar, so that the droppers are retained
in the positions as selected by the pattern on the cards, during the whole time
the needle bar is at or near its lowest position.
In some cases it is desirable that a pattern shall be produced, which shall
consist of two or more distinct designs. For example in a hose one or more
designs may be used to form a heading and another design, which may be con-
tinually repeated, may be used to form the leg of the hose or body of the pattern.
To do this, by simply bringing fresh cards into action for each course of work,
a very large number of cards would be required, but my invention enables a band
of cards to be so arranged and used, that one portion of the band of cards shall
come into action once, each card in consecutive order. The remaining portion
of the band of cards can be repeated as many times as desired. This I effect as
follows: Taking for instance a band of cards for forming a heading followed
by a pattern or design that is required to be repeated, during the formation of the

page_text: heading, the band of cards is advanced, one card at a time, and each card comes
into action in consecutive order.
-
Then when the heading is completed, the cylinder shaft is racked twice between
each selection of needles, so that every second card comes into action. Then
when a certain portion of the band of cards is reached, their movement is reversed,
and the cards which where passed over as the band of cards advanced, are brought
into action as they return. For example:-If the number of cards necessary
to form a certain pattern, be eight, then I arrange and lace them up as follows:-
1 8 2 7 36 4 5. After No. 1 has been in action, the card cylinder shaft is
racked forward twice. This brings No. 2 into action, again it is racked twice,
when No. 3 comes into action, and again so for No. 4. Then it is only racked
once, which brings No. 5 into action. Then the movement of the band of cards
is reversed and racked back twice, this brings No. 6 into action and so on for
Nos. 7 and 8 when it is again racked only once, which brings No. 1 into action
again. This completes the cycle of movements. The movement of the band of
cards is again reversed, and these movements and reversings are continued for
as long as desired. These movements of the band of cards I effect as follows:-
Two ratchets are so arranged as to act upon two ratchet wheels, one ratchet wheel
is fast to the cylinder shaft, and the second ratchet wheel works upon a stud, and
is geared to the cylinder shaft by a pair of gear wheels so that when one ratchet is
in action, the cylinder shaft is rotated in one direction, and when the other
ratchet is in action, the shaft is rotated in the opposite direction. The two
ratchets are provided with suitably shaped tails which are acted upon by small
cams carried by a light shaft in such a manner that when the said light shaft
is turned into one position, one ratchet will be in action, and when turned into
another position, the other ratchet will be in action. A suitable chain is caused
to move one or more links, with each movement of the band of cards. This chain
is provided with suitable studs or inclines, which come into action at the time
it is desired to change the movement of the band of cards, the said studs or
inclines lift certain levers which throw into action a ratchet, which acts upon
a ratchet wheel, which is fast to the aforesaid light shaft, by which means the
light shaft is turned, and one ratchet is brought into action, and the other thrown
out of action as herein before described, and the movement of the band of cards,
is thereby reversed. The two ratchets may be worked by one cam, which imparts
to them a double movement between each selection of needles, but during the time
that the band of cards is required to advance one card only at a time (i.e. during
the formation of a heading for instance as herein before described) the advancing
ratchet although having two movements only racks the card cylinder shaft at
one movement, an independent cam acts upon the tail of the said ratchet and
holds it out of action at each alternate movement. Then when the repeating
portion of the band of cards is reached, this last named cam is automatically
thrown out of action and the ratchet then acts twice between each selection of
needles as herein before described.
This arrangement will be understood by referring to Figs. 6, 7 and 8, Sheets 3
and 4. Figure 6 is a part elevation of the arrangement with some adjacent parts.
Figure 7 is a plan of part of Figure 6, and Figure 8 is a part plan of the racking
arrangements at the end of the frame.
A rack wheel K Figures 6 and 8 is fast to the cylinder shaft D², a second rack
wheel K works upon a pin or axle carried by the arm 17 and the two rack wheels
are geared together by the equal gear wheels 2 so that the two rack wheels K
and K turn in opposite directions.
Upon any convenient part of the shaft D2 a wheel may be fixed. This wheel
may have four nicks or indents cut in its edge, and a retaining spring may act
therein so as to retain the cylinder shaft D³ in any one of its four positions. A
lever K may work upon a fixed pin or axle K attached to any convenient part
of the framing of the machine. This lever may receive suitable motion from a

page_text: cam K upon the main shaft K6. The top end of this lever K³ carries a pin or
axle, by which two ratchets K7 K8 are carried. These ratchets act upon the two
ratchet or rack wheels K K'.
1
It will be seen that when the ratchet K7 is in action, the band of cards will
be moved in the direction of the arrow K³ Figure 6, and when the ratchet K8 is
in action, the band of cards will be moved in the opposite direction. The
ratchets K7 KS have tails or extensions. K10K which
pass beneath a light
shaft L which is carried in fixed bearings, which may be attached to any convenient
part of the framing of the machine. Fast to this shaft L is a double cam K12 K
Figures 6 and 7, the cam K2 acting upon the tail K10 of the ratchet K' and the
cam K acting upon the tail K" of the ratchet Ks. These cams are so shaped
that when the shaft L is in one position (Figure 6) the cam K12 will press upon
the tail K10 of the ratchet K and hold it out of action, and at the same time the
cam 3 will be free from the tail K" of the ratchet K8 and so allow it to drop
into action. Then if the shaft L be turned half a revolution the order will be
reversed riz.-the ratchet K' will be in action, and the ratchet KS will be out of
action, and if the shaft L be turned one quarter revolution from the position
shown in Figure 6 in either direction, then both ratchets K7 K8 will be out of
action.
A step by step turning movement can be imparted to the shaft L in the following
manner:-
The shaft L has fast upon it a ratchet or rack wheel L¹, Figures 6 and 8. A
lever L² may work upon a fixed axle similarly located to the axle K, and be
worked by a suitable cam L17 upon the main shaft K. The top end of the lever L²
carries a ratchet L³, which acts upon the ratchet wheel L¹. The ratchet L³ can
be held out of action by a pin L at the end of a lever L5 which may work upon
a fixed pin or axle L6 attached to any convenient part of the framing of the
machine.
To the other end L7 of the lever L³ a connecting rod LS is attached. This
connecting rod is also jointed to the lever L' which works upon the fixed stud or
axle L which may be fast to any convenient part of the framing of the machine.
Upon the end of the cylinder shaft D is a suitably shaped four toothed wheel L¹2
which is placed immediately above the end L of the lever L seen best in l'igure 8.
Around this wheel L2 a suitable endless chain L3 passes. Upon this chain are
two studs or inclines L14 L15 which act upon the end L" of the lever L. To the
end of the lever L' one end of a spring L¹ may be attached, the other end of which
may be attached to any convenient part of the framing of the machine. It will
be seen that when a stud or incline such as L15 presses upon the end L" of the
lever L (as shown in Figure 6) the pin L upon the end of the lever L5 is lowered
whereby the ratchet L³ falls into action with the ratchet wheel L' and the shaft L
will then be rotated one quarter of a revolution for each complete movement of
the lever L2 and when there is no stud or incline pressing upon the end L" of the
lever L the spring L16 will cause the pin L to rise whereby the ratchet L³ will
be held out of action. The movements imparted to the ratchet L³ through the
lever L are such as to cause the ratchet L³ to move or rack twice between each
selection of the needles by the cards, each movement of the ratchet L³ following
immediately after the movement of the ratchets K7 K³.
To make the relative movements of the mechanism just described (and shown
in Figures 6, 7 and 8) clearer, I will consider them in conjunction with the con-
struction and method of lacing up the band of cards. I will first explain the
reversing movements of the repeating portion of the band of cards herein before
described.
Taking the number of cards in the repeating portion of the band of cards as
eight, and suppose there are ten cards required to form the heading, then cards
Nos. 1 to 10 would be the non-repeating cards, and cards 11 to.18 the repeating
cards and the whole band of cards will be laced together as follows:-1 2 3 4
5 6 7 8 9 10 11 18 12 17 13 16 14 15.

page_text: The band of cards having been advanced one card at a time for cards Nos. 1
to 11 the ratchet K' will be in action, and will then rack the band of cards forward
twice between each selection of needles so that cards Nos. 11, 12, 13 and 14, come
into action in regular order as herein before described.
Then after No. 14 card has been presented (i.e. acted upon the droppers, and so
made a selection of needles to be brought into action) the first time the ratchet K
is advanced No. 15 card is brought into acting position and at the same time the
stud L15 upon the chain L3 depresses the end L" of the lever L³ whereby the
ratchet L³ is brought into action and the shaft L is rotated one quarter revolution
as herein before described. This movement of the shaft L turns the cams K12 K13
into such a position that both the ratchets K K8 are thrown out of action as
herein before described. Thus when the ratchet K7 advances for the second time
it is held out of action and the cylinder shaft D2 is not racked so that No. 15 card
is presented to make the next selection. The stud L15 being still in contact with
the lever L the ratchet L³ (which moves immediately after the ratchets K7 K³)
again racks the shaft L one quarter of a revolution which brings the cams K2 K3
into the position shown in Figure 6 when the ratchet K8 is brought into action,
and the ratchet K is lifted out of action, so that before the next selection of
needles the ratchet K8 will rack the band of cards back two cards which brings
No. 16 into acting position and so on for Nos. 17 and 18. After No. 18 has been
in action, the first time the ratchet K8 is advanced, No. 11 card is brought into
acting position, and at the same time the stud L on the chain L3 acts upon the
lever L whereby the ratchet L is brought into action. The shaft L is rotated
one quarter of a revolution and the ratchets K7 K8 are thus both lifted out of
action, while the ratchet K8 is advanced for the second time so that the cylinder
shaft 2 is not racked and this leaves card No. 11 to make its selection. The
second racking movement of the ratchet L³ which follows the second racking
movements of the ratchets K7 K8 again turns the shaft L one quarter revolution,
bringing the ratchet K7 into action and throwing the ratchet K8 out of action.
This completes the cycle of movements which is repeated as often as may be
desired.
I will now describe the mechanism which governs the movements of the band
of cards during the formation of the heading. These movements precede the
reversing movements herein before described.
During the formation of the heading the band of cards has to advance one card
only at a time, between each selection of needles each card coming into action
in consecutive order. To do this the ratchet K has to be in action, but as the
ratchet K moves twice between each selection of needles as herein before described,
it is necessary that it shall be held out of action, every other time, so that it shall
only rack once between each selection.
This is effected by shifting the shaft L endwise so that the cam K12 no longer
acts upon the tail K10 of the ratchet K' and in place of it another cam K16 having
two noses K K is brought into position to act upon the tail of the ratchet K
and hold it out of action every other time that it makes its forward movement.
The mechanism for effecting this I will now explain. To the end of the shaft L
a wheel or collar M is fast Figure 8. M' is part of the framing of the machine
or of a bearing attached thereto through which the shaft L passes. Upon the
bearing a suitable shaped incline M2 is fixed. The wheel or collar M is cut
out to fit over the incline M2 so that when the shaft L is turned or rotated for
the first time (after starting the band of cards) by the ratchet L³ as herein before
described the incline M2 bearing upon the wheel or collar M causes the shaft L
to move endwise in the direction of the arrow Figure 8 whereby the cam
noses KK are moved out of action and the cam K12 into action over the tail K0
of the ratchet K. The cam K6 which has the two herein before described
noses KK" works freely upon the shaft L and has a prolonged boss sleeve or
collar N. Fast upon this sleeve or collar is a rack wheel N2, Figures
and 10,

page_text: the lever K3 carries an additional ratchet N³ which acts upon the rack wheel N
and so turns the collar N and consequently the cam noses K" K" also. When
the shaft L is in the position shown in Figure 8 the cam noses K17 K17 are above
the tail K10 of the ratchet K' and the ratchet N³ is in contact with the rack
wheel Nº. When the cam noses K" K are in the position shown in Figure 8
the ratchet K will be held out of action and will not rack the shaft D². Then
as the ratchet K' retires the ratchet N³ will rack the collar N one quarter revolu-
tion and the cam noses K K are brought into such a position that they do not
act upon the ratchet K when the ratchet K' will be in action so that as the
ratchet K advances for the second time the shaft D2 will be racked, then when
the ratchet K7 again retires the collar N will be again racked one quarter revolu-
tion, whereby the ratchet K is again thrown out of action. Thus the ratchet K'
racks the cylinder shaft D2 at every other advance and so the band of cards is
advanced one card only between each selection of needles.
A suitable friction clip (not shown) may embrace the collar N in order to
prevent it running back with the ratchet N³ when it retires. An arm or collar P
is fast to the shaft L. To this arm a pawl or ratchet P¹ is jointed, and engages
with a suitable nick in the boss of the rack wheel N or the collar N, this pawl
may be held in its nick by a spring as shown.
Before starting the machine on the fancy work pattern the shaft L is turned
round by hand until the recess in the wheel M (Figure 8) is opposite the incline M².
The shaft L is then pushed endwise into the position shown in Figure 8.
In turning the shaft L into this position the pawl P¹ (Figures 8 and 10) engages
with the nick in the boss of the ratchet wheel N³ and turns it and consequently
the cam noses K K also into the correct position for starting the band of cards.
The machine is then started. The ratchet K' racks the band of cards one card
at a time between each selection of needles as herein before described until the
heading is completed when the stud L15 upon the chain L¹³ comes into action.
The shaft L is rotated one quarter revolution and at the same time is shifted end-
wise by the incline M¹ as herein before described whereby the cam noses K" K17
are thrown out of action and the cam K12 into action, and the band of cards is
then advanced two cards between each selection of needles except when the move-
ment of the band of cards is reversed as hereinbefore described. A ratchet Pa
attached to any convenient part of the framing may carry a pin P³ to support
the ratchet N³ when the rack wheel N2 is moved from under it by the endwise
movement of the shaft L hereinbefore described.
In some cases instead of the two ratchets K7 K8 being carried by one lever as
herein before described they may be carried by independent levers, and in some
cases the ratchets may be cut in opposite directions and act upon two rack wheels
which are both fast to the shaft 12 so that the one ratchet turns the shaft in one
direction and the other ratchet turns it in the opposite direction.
It will be evident that in some cases instead of using bands of cards as herein
before described, jacquard drums or cylinders may be used. The rows of perfora-
tions or pegs being arranged precisely in the same relative order as the cards in
the band of cards herein before described, so that when these drums or cylinders
are racked or rotated by the racking arrangements as herein before described
in relation to the band of cards, they may be caused to present their rows of
perforations or pegs in regular consecutive order for a certain number of courses
and then to repeat in a precisely similar manner to that described in relation to
the band of cards.
When a large number of cards are required to form a pattern or series of
patterns, it is sometimes desirable that they should be together in a heap or in
folds so as to occupy as little room as possible while out of action and the space
available for this purpose is not always in the immediate vicinity of their position
when in action. In order to convey them to and from their storage place and
their acting position I arrange two sets of auxiliary card cylinders in a convenient

page_text: position near the place of storage. The band of cards passes over one cylinder
on its way to action and over the other on its way back to the place of storage.
The rotation of the ordinary card cylinder which presents the cards when in
action will draw the cards from their resting place and I cause the auxiliary
cylinders to draw them back again. But as the band of cards may sometimes
move in one direction and sometimes in the other as hereinbefore described it
will be seen that each of the auxiliary card cylinders must in turn draw the cards
back to their resting place or place of storage. This I effect as follows:-Each
of the shafts which carry the auxiliary card cylinders are provided with a sliding
gear wheel or equivalent, which may slide upon a feather" in the said shaft.
Each of these sliding gear wheels may engage with a third gear wheel which may
be carried by and work upon a stud. This wheel I will call the stud wheel. This
stud wheel is attached to a pulley, around which a cord is passed one end of the
cord is made fast to the pulley and to the other or free end is attached a weight
or equivalent. This weight always tends to turn the stud wheel in one direction
so that whichever sliding gear wheel is in gear with the stud wheel, the corres-
ponding auxiliary card cylinder will be turned by the action of the said weight
and the slack cards will thereby be drawn into their place of storage.
66
The same mechanism which reverses the band of cards may also govern the
sliding gear wheels throwing them in and out of gear with the stud wheel as
required.
The weight may be kept wound up by means of a second cord one end of which
may be attached to the said pulley and the other end to a lever worked by a cam
or equivalent.
This arrangement will be understood by referring to Figures 11 to 14 Sheet 5.
Figure 11 is a part elevation of the mechanism and some adjacent parts. Figure 12
is a plan of parts of same. Figure 13 is a front view of parts of Figure 11 and
Figure 14 is a front view of parts of Figure 12.
RR are the auxiliary card cylinder shafts upon which are the sliding gear
wheels R2 R a third gear wheel R4 works upon a stud or shaft in a fixed
bracket R³. A link Re is centered upon a suitable stud or pin in the bracket R³.
This link R6 has two pins R7 R7 projecting from its surface and fitting into two
grooves R8 R9 in the bosses of the gear wheels R³ R³. It will be seen that by
these means when the wheel R2 is in gear with the wheel R the wheel R³ will
be out of gear and vice versa. A bell crank lever S Figures 11, 12 and 14 is
carried by a suitable fixed stud or axle which may be carried by a bracket S¹
attached to any convenient part of the framing of the machine one end S³ of this
lever S fits into the groove R8 in the gear wheel R2 and to the other end S³ of
the lever S a connecting rod or link S is jointed. This link connects the lever S
to the lever S5. This lever S5 works upon a fixed pin or axle S6 attached to any
convenient part of the framing of the machine. The other end S7 of the lever S³
is acted upon by a cam S8 upon the shaft L and a spring S⁹ acts upon the end S7
of the lever S5 and keeps it in contact with the cam S8. It will be seen that by
the action of the cam S8 and the spring S the gear wheels R2 R3 are thrown in
and out of gear with the gear wheel R. This cam S8 is so shaped and set that
when the ratchet K8 (Figure 6) is in action the cam S8 will be in the position
shown by full lines in Figure 11 and the auxiliary card cylinder shaft R will
be geared to the wheel R4 and when the ratchet K' (Figure 6) is in action the
cam S8 will be in the position indicated by dotted lines in Figure 11 and the
auxiliary card cylinder shaft R₁ will gear to the wheel R and the cylinder
shaft R will be out of gear. The necessary movement is imparted to the gear
wheel R as follows:-
Upon the boss of the gear wheel R a pulley T is free to turn Figures 11 and 12.
Fast to the boss of the gear wheel R is a ratchet wheel T. Upon the pulley T
is a ratchet or pawl T3 (seen best in Figure 11) which is kept in contact with
the ratchet wheel T¹ by a suitable spring. One end of a cord (or equivalent) is

page_text: attached to the pulley T and passes round it, the opposite end is fast to a weight T5..
It will be seen that this weight T5 tends to turn the pulley T (and consequently
the gear wheel R* also) in the direction of the arrow T (Figure 11) so that when
the gear wheel R2 is in action the auxiliary cylinder shaft R will be turned
in the direction of the arrow T8 and the cards will be drawn from the lower sides
of the card cylinder D³ and when the gear wheel R³ is in action the auxiliary
cylinder shaft R' will be turned in the direction of the arrow T and the cards
will be drawn from the upper side of the card cylinder D³. The cards after they
have been drawn off by the auxiliary card cylinders as herein before described
may fall in a heap into any convenient receptacle or hung by suspenders in the
usual well understood method of storing cards. A second cord (or equivalent) V
may be also attached to the pulley T but wound round it in the opposite direction
to the cord T. The other end of the cord V may be attached to a lever V₁ which
may work upon a suitable fixed axle V2.
This lever V may receive a suitable motion from a cam V³ upon the main
shaft K. It will be seen that the movement of the lever V₁ will continually
wind up the weight T5 and also leave it free to draw the cards from the card
cylinder D3 after presentation as herein before described.
A suitable retaining
spring may be attached to the gear wheel R¹ so that when the lever V₁ is winding
up the weight T5 the gear wheel R' will not be turned back or the tension removed
from the band of cards.
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

to the needle bar and droppers are used to hold them fast with the needle bar
the employment of cams or equivalents carried by a rod or shaft, by turning which
the cams or equivalents can be brought into position to act upon and throw out
of action certain droppers, whereby certain needles are thrown out of action
independently of the selection made by the cards substantially as herein before
described.
11. In a rotary or flat bar knitting machine where the needles are not fast to
the needle bar the employment of sliding needle jacks having two catches one
to engage with the dropper and the other to engage with the selvedge needle
lifter substantially as herein before described.
12. In a rotary or flat bar knitting machine where the needles are not fast to
the needle bar carrying the card cylinders upon arms or brackets independent
of the needle bars so that the cards need not rise and fall with the needle bar but
can be made to follow its to and fro knocking over movements substantially as
hereinbefore described.
13. In combination with a rotary or flat bar knitting machine where the needles
are not fast to the needle bar but are selected by droppers acted on by jacquard
cards the arrangement of the jacquard cards in such a manner that a certain
number of them are laced together in such relative order that each and every
card of this portion of the band of cards is presented in the desired consecutive
order to keep repeating one complete design when this portion of the band of cards
is racked forwards and backwards substantially as herein before described.
14. In combination with a rotary or flat bar knitting machine where the needles
are not fast to the needle bar but are selected by droppers acted on by jacquard
cards the arrangement of jacquard cards used for acting upon the droppers in
such relative order that a certain number of them laced together are when moved
forwards presented in regular consecutive order to form one or more designs, the
remainder of the band of cards forming another design being so laced together
that each and every card of this portion of the band of cards is presented in the
desired consecutive order when this portion of the band of cards is racked forwards
and afterwards backwards substantially as hereinbefore described.
15. In combination with a rotary or flat bar knitting machine where the needles
are not fast to the needle bar but are selected by droppers acted upon by jacquard
cylinders, the arrangement of the rows of perforations or pegs in such relative
order that a certain number of them when the jacquard or cylinder is racked
forwards are presented in regular consecutive order to form one or more designs,
the remainder of the rows of perforations or pegs forming another design being
so arranged upon the jacquard cylinder that each and every row of perforations
or pegs of this portion of the jacquard cylinder is presented in the desired con-
secutive order when this portion of the jacquard or cylinder is racked forwards
and afterwards backwards.
16. In combination with a rotary or flat bar knitting machine where the needles
are not fast to the needle bar but are selected by droppers acted on by jacquard
cards or cylinders the employment of two pawls or ratchets jointed to one lever
and acting upon two rack wheels geared together for turning the card cylinders
backwards or forwards substantially as herein before described.
17. In combination with a rotary or flat bar knitting machine where the needles
are not fast to the needle bar but are selected by droppers acted on by jacquard
cards or cylinders the employment of two pawls or ratchets carried and worked
by independent levers and acting upon rock wheels fast to the cylinder shaft for

page_text: turning the card cylinders backwards or forwards substantially as herein before
described.
18. In combination with a rotary or flat bar knitting machine where the needles
are not fast to the needle bar but are selected by droppers acted on by jacquard
cards or cylinders the employment of cams or equivalents to act upon the tails
or extensions of the card cylinder racking pawls or ratchets, whereby they are
thrown in and out of action automatically to turn the card cylinder shaft back-
wards or forwards as desired substantially as herein before described.
19. In combination with a rotary or flat bar knitting machine where the needles
are not fast to the needle bar but are selected by droppers acted on by jacquard
cards controlling the movements of the above mentioned cams by the action of
a supplementary chain or band moved synchronously with the band of cards
substantially as herein before described.
20. In a rotary or flat bar knitting machine (where the needles are not fast to
the needle bar), the method of conveying the cards to and from the acting card
cylinder and the place of storage substantially as herein before described.
