Year: 1881

page_text: PROVISIONAL SPECIFICATION left by the said Arthur Paget at the Office
of the Commissioners of Patents on the 13th August 1881,
ARTHUR PAGET, of Loughborough, in the County of Leicester.. "IMPROVE-
MENTS IN KNITTING MACHINERY."
The object of my Invention is to facilitate the production of knitted fabrics
upon what are well known as "Paget's Patent frames," and other knitting
machines, by means of improvements which facilitate the construction and
working of such knitting machines. Some of these improvements are specially
applicable to wide machines with several divisions, and the improvements increase
the strength, lightness, and speed, of such machines.
The first part of my Invention relates to an arrangement of a thread-layer
slide or slides hanging or gripping, or both, upon a tube or rod which being caused
to traverse to and fro carries with it the thread-layer-slide or slides by the friction
created by their weight or grip, or both, thus causing them to pass across the
needles. The slides thus moved with the tube may be stopped at any required
point, and when they are so stopped they are prevented from rebounding by the
continued friction of the rod or tube only, or by any of the well known methods
in addition thereto. The rod or tube is also an axis round which any of the
thread layer slides can be turned out of position when not required for use.
The second part of my Invention relates to a method of constructing, arranging,
connecting, and stopping two or more sets of thread layer slides which readily
permits the sets of slides thus constructed to be turned round a tube as an axis in
or out of action when required for making the heels at the end of the legs or for
making legs, heels, and insteps. Each set of slides is connected by strong and
light metallic tubes passing through and secured to sockets projecting from the
thread layer slides by running type-metal (or other similar suitable material) into
the space between the tubes and the sockets. The thread-layer-slides are thus
easily, accurately, and durably connected. The thread layer slides are stopped by
the ends of the tubes which are arranged to abut against suitable adjustable
projections on stopping slides which are narrowed inwards (or shogged) by
shogging ratchets which do not themselves shog or narrow inwards.
The third part of my Invention relates to the construction of what are well
known as drawing-across pullies. I make them with fingers pivotted on a point
within the periphery of the pulley in such a manner that these pivotted fingers

page_text: can recede, and thus at any required moment instantaneously (or if desired with
an amount of continued tension which can be regulated at pleasure) release what
is ordinarily known as the drawing across bob, and the end of the cord or belt for
drawing across the sinker incline.
The fourth part of my Invention relates to the use (with the before mentioned
drawing across-pulley) of bob lifters for lifting the drawing across bobs off the
periphery of the drawing across pulley so as to prevent them from being caught by
the fingers and carried round with the pulley.
The fifth part of my Invention relates to an arrangement of locking-latch
pivotted (or sliding in guides) on the incline-slide bar lifted by and then acting
against a projection formed upon or rigidly attached to the incline slide for the
purpose of preventing any rebound of the incline-slide when it is stopped at the
end of its traverse, and liberating the incline slide when it is unlocked or unlatched
by means of the thread-layer lifting bar, or by a cam or other convenient moving
part of the machine.
In cases where the drawing across motion is obtained by the revolution of a
cylinder with belical projections or grooves actuating a pivotted lever, it is of
advantage to provide for arresting the lever at any part of its movement.
The sixth part of my Invention relates to means of effecting this by disengaging
the part which communicates the motion to the lever from the helices on the
cylinder.
The seventh part of my Invention relates to an arrangement for guiding and
partly balancing the weight of bars required for welting and other similar
purposes, which arrangement enables the operation of welting and other similar
processes to be performed with speed, accuracy, and facility, even up.on wide
machines, comprising several divisions, and in such machines a number of welts
may be made simultaneously, and at one operation instead of as hitherto by a
separate operation for each division.
The eighth part of my Invention relates to an arrangement of a sliding frame
for carrying the coverers, and to a mode of actuating it by cams and by curved
inclines and parallel surfaces in such a manner as to impart any required.
inovements to the coverers when narrowing the fabric.
The ninth part of my Invention relates to an arrangement for facilitating the
manipulation of what are well known as picking-up-bars or putting on bars by
another and distinct use of the sliding frame before referred to as used for
narrowing.
The tenth part of my Invention relates to an arrangement of a sliding frame for
carrying what are well known as "needle bars," which sliding frame is actuated
by cams and inclines. or curved surfaces in such a manner as to impart any
required movements to the needles when making web and narrowing.
The eleventh part of my Invention consists of an arrangement of a sliding
frame carrying the "needle bars" modified so as to dispense with the jointing of
the bars to the sliding frame, the required inclinations being given to the needles
by suitably formed curved inclines or cams so as to determine the up and down
movements of the sliding frame.
The twelfth part of my Invention relates to an arrangement for moving the
sinker incline upwards and downwards when required to perform the operation
well known as "altering the stiffness" by means of an arrangement of a wedge
screw and "star wheel" combined.
. The thirteenth part of my Invention relates to an arrangement for using what
are known as knocking over bits hooked at the upper end and sliding in grooves
in the face of the knocking over bar, so that the needles are supported by the
walls of the said grooves, and the hooks are formed in such a manner that in the
operation of narrowing the loops are pushed towards the heads of the needles by
the face of the hooks when the loops are "picked up" by the coverers.

IN KNITTING MACHINERY."
"IMPROVEMENTS
The object of my Invention is to facilitate the production of knitted fabrics on
what are well known as Paget's patent frames, and other knitting machines, by
means of improvements which greatly facilitate the construction and working of
such knitting machines. Some of these improvements are specially applicable to
wide machines with several divisions, and the improvements increase the strength,
lightness, and speed of such machines. I will describe these improvements with
reference to the accompanying Drawings, .and the figures and letters marked
thereon. Wherever in these Figures the same letters of reference occur they are
to be understood as indicating corresponding parts.
The first part of my Invention relates to an arrangement of a thread-layer-slide
or slides, hanging or gripping, or both, upon a tube or rod, which being caused to
traverse to and fro carries with it the thread-layer-slide or slides by the friction
created by their weight or grip, or both, thus causing them to pass across the
needles. The slides thus moved with the tube may be stopped at any required
point, and when they are so stopped they are prevented from rebounding by the
continued friction of the rod or tube only, or by any of the well known methods in
addition thereto. The rod or tube is also an axis, round which any of the thread-
layer slides can be turned out of position when not required for use. Figs. 1, 2,
and 3 on Sheet I. (in conjunction with others of the Drawings) shew an arrange-
ment for carrying out this part of my Invention. Fig. 1 is an end view of a thread-
layer-slide and other adjacent parts of the machine. Fig. 2 is a part front view of
the same. Fig. 3 is a sectional plan of parts of the same. The incline slide A is
drawn across the frame from one side of the machine to the other by cords or by
any of the usual methods. This incline slide A carries with it the bracket A¹ and the
thread-layer-slide tube B, and thus the requisite motion is imparted to the clips B',
which hang upon or grip the thread-layer-slide tube B. These clips are attached at
the lower end to the thread-layer-slide-casings B³, which carry the thread-layer-
slides B, which carry the thread tubes B. The thread-layer-slides are thus carried
across the frame until they are stopped by a stop of the ordinary kind, or of the
kind hereinafter described. The incline slide A carrying the slide-tube B continues
its traverse after the thread-layer-slide itself is stopped, the tube B then sliding
through the clips B', and during this part of the traverse of A, the thread-layer-
incline B (which is attached to the incline slide A impinges on the incline top B
of the thread-layer driving it downwards, and so carrying the thread-tube B'
downwards between the needles in the usual manner to form the selvedge. The
incline slide still continues its traverse until it ceases or is stopped. The needles
go through the usual motions, being fixed in a bar carried by a rocking shaft
moved by cams, or in any of the other usual well known methods, and before the
thread layer and the thread tube begin to traverse back again the thread layer
lifting bar B' lifts the thread layer slide by its peg B³ ready for its next traverse.
The thread layer-lifting bar can be lifted by rods and a rocking shaft, or by any of
the other well-known methods usually employed for lifting the thread-layer-lifting-
bar or sinker-lifting-bar. The incline-slide now begins its traverse in the opposite
direction, when a similar series of movements is repeated as usual. When required
the thread layer may be turned up on the tube B (as an axis), being thus taken out
of action, as shewn in dotted lines in Fig. 1; and when they are so turned up the

page_text: threads from them will not be laid upon the needles during the traverse of the
thread layer. The thread layer slide tube B may be supported by a fixed rod
passing through it, and thus may be considerably lightened, as shewn in Fig. 4,
which is a part front view, and Fig. 5, which is a transverse section. B is the
thread-layer-slide-tube, and C is a fixed rod along which it slides supported by
bush bearings C³. The rod C is attached by brackets C' to the incline-slide-bar 09.
The second part of my Invention relates to a method of constructing, arranging,
connecting, and stopping two or more sets of thread-layer-slides; Figs. 8 and 9,
Sheet II, shew an end view partly in section and a front view of the thread-layer-
slides for one division of a machine arranged for forming the legs, heels, and
insteps of hose. It will be seen that this method of constructing the thread-
layer-slides readily permits the required set of slides thus constructed to be turned
round the tube B as an axis in or out of action when required for making the
heels at the end of the legs, or for making legs, heels, and insteps. Each set of
slides is connected by strong and light metallic tubes passing through and secured
to sockets projecting from the thread-layer-slides by running type metal (or other
similar suitable material) into the space between the tubes and the sockets. The
thread-layer-slides are thus easily, accurately, and durably connected; Figs .1, 2, 6,
and 7 Sheet I, also shew this method of construction, connection, and arrangement;
Fig. 1 shews an end view of the sockets on the end thread-layer-slide; Fig. 2 shews
a front view of the same with part of the connecting tube attached thereto;
Fig. 6 shews the tube passing through a socket upon an intermediate thread-layer-
slide; and Fig. 7 is a transverse section through a socket and tube and their
metallic connection; D; D, are the abutment sockets to allow the thread-layer
slides to be stopped by the stops hereinafter described, and D¹, D', are the
intermediate sockets upon the thread-layer-slides; D2, D3, are the metal tubes; D³
the metallic connection; Figs. 10, 11, and 12, Sheet III, shew the method of
stopping the thread-layer-slides at the end of their traverse; Fig. 10 is an end view
of a left hand thread-layer-slide stop and its holder, and other adjacent parts;
Fig. 11 is a front view thereof; and Fig. 12 is a plan. The arrangement and
action are as follows:-The shogging rod E (worked by a cam or by any other of
the well known methods) is connected to the moveable axis E¹ upon which are
pivotted, first, the shogging joint E³ (which at its other end turns upon a fixed
fulcrum Es), and secondly, the shogging-ratchet joint E, the other end of which is
pivotted to the shogging ratchet E³. On the shogging rod E being pushed in the
direction of the arrow E¹, the moveable axis E' with its joint Es moves outwards,
turning radially round the fixed fulcrum E³, and thus drawing the shogging ratchet
joint backward and with it the shogging ratchet E, which has teeth upon its
face coinciding with the gauge of the machine, engaging into similar teeth on the
face of the thread-layer-slide stop E. The teeth on the ratchet E' are thus made
to engage with other teeth upon the face of the thread-layer-slide-stop Ee. On the
shogging-rod E being drawn back towards its former position, the shogging-
ratchet joint E is pushed out, and consequently pushes the thread-layer-slide
stop E with it, and the joint E' comes against its stop E' and the thread layer
slide stop will then reduce the traverse of the thread layer slide. The spring Es
keeps the shogging ratchet Es engaged with the thread-layer slide stop E; E the
holder for carrying the thread-layer-slide stop E is attached to the knocking-
over bar or other convenient part of the machine; E1, E10, are set screws for
adjusting the position of the thread layer sides of which the abutments are
shewn in D, D. The spring Es acting against the projecting hooks E" can also
be used for lifting the shogging ratchet out of gear when it is required to set the
thread-layer-slide-stops by hand to any required position.
The third part of my Invention relates to the construction of what are well
known as drawing-across-pulleys, I make them with fingers pivoted on a point
within the periphery of the pulley in such a manner that these pivotted fingers
can recede, and thus at any required moment instantaneously (or if desired with
an amount of continued tension which can be regulated at pleasure) release what

page_text: is ordinarily known as the drawing-across-bob, and the end of the cord or belt for
drawing across the sinker-incline-slide.
Figs. 13, 13, 14, 16, 16ª, 16b, 16ª, 16, and 16º, Sheet IV. (in conjunction with
others of the Drawings), shew an arrangement for carrying out this part of my
Invention. Fig. 13 is a side view of a drawing-across-pulley, and its adjacent
parts shewing the fingers engaged with the drawing across bob. Fig. 14 is a
section of the same through Z, Z. Fig. 16a is a section of the same through Y, Y.
Fig. 13 is a part side view shewing the position of the fingers when disengaged
from the drawing-across-bob. Fig. 16b is a side view of the fingers detached.
Fig. 16° is an end view of the same, and Fig. 16d is a plan of the same. Fig. 16°
shews a modified shape of the disengaging incline F³. On the pulley F being
caused to revolve in the direction of the arrow by the ordinary cam shaft or other
shaft on which it may be placed, the projecting pivotted fingers F¹, F¹, catch the
bob F, and carry it round with them, until the required drawing across motion is
completed, the bob will then cause the fingers to turn upon their pivot at the
moment when the tail end F³ of the fingers has arrived at the end F¼ of the
segmental incline F, which has previously supported it, as shewn in Fig. 13. The
continued revolution of the pulley, and the resistance of the bob will then cause
the fingers to turn, until they recede towards the periphery of the pulley, and so
release the bob, as shewn in Fig. 13ª. A spring F6 acting against the tail of the
fingers, as shewn, restores them to position after they have escaped beneath the
bob. The latch F is for the purpose of supporting the pivotted fingers while they
are acting upon the bob (during the drawing-across-motion), and F7 is thrown out
of gear by means of the incline surface or cam F8, after the tail end of the fingers
commences to be supported by the segmental incline F. A spring Fº is employed
for keeping the latch in gear with the fingers. The segmental incline Fs can, if
desired, be continued beyond F4, as shewn in Fig. 16º, so as to release gradually the
fingers F¹ (and consequently the drawing across bob F) with an amount of con-
tinued tension, which can be regulated at pleasure. The arrangement of the pulley
is only shewn for one belt F", it is obvious that two sets of fingers on the pulley
may act on the two drawing across cords or belts working on one pulley, as is
usually employed, or there may be a separate drawing-across-pulley at each end of
the machine, as may be most convenient.
The fourth part of my Invention relates to the use of bob-lifters for lifting the
drawing-across-bobs off the periphery of the drawing across pulley, so as to prevent
them from being caught by the fingers, and carried round with the pulley.
Figs. 13, 15, 15, and 16, Sheet IV. (in conjunction with others of the Drawings)
shew an arrangement for carrying out this part of my Invention. Fig. 13 is a side
view of the bob lifters and adjacent parts when out of action. Fig. 15 is an end
view thereof. Fig. 15ª is a side view of the same when in action, and Fig. 16 is a
plan of the drawing-across-bob. The bob lifters G, G, are pivotted at a point G¹
outside the periphery of the drawing-across-pulley F, as shewn in Fig. 13. When
the drawing-across-bob is required to be lifted, then the bob lifters are turned upon
the pivot into the position shewn in Fig. 15, by means of the rod G³ (which
can be worked from the narrowing handle, or by any other suitable woll known
means), by which means the bob lifters come in contact with the lateral pro-
jections Flo upon the drawing-across-bob, and so lift the bob away from the surfaco
of the pulley, and thus arrest the drawing-across-motion while the pulley continues
to revolve.
The fifth part of my Invention relates to an arrangement of locking-latch
pivotted (or sliding in guides) on the incline-slide-bar lifted by and then acting
against a projection formed upon or rigidly attached to the incline-slide, for the
purpose of preventing any rebound of the incline slide when it is stopped at the
end of its traverse, and liberating the incline slide when it is unlocked or
unlatched by means of the thread-layer-lifting-bar, or by a cam or other con-
venient moving part of the machine; Figs. 17, 18, and 19, on Sheet V. (in
conjunction with others of the Drawings) shew this arrangement; Fig. 17 is an

page_text: end view;, Fig. 18, a front view, and Fig. 19 is a plan of the arrangement at one
end of the machine, which is similar to that at the other end. The locking-
latch H works on a pivot H¹ carried by the bracket H upon the incline-slide-bar C³.
This latch during the latter portion of the motion of the incline-slide is lifted by a
projection H³, and held up until the incline-slide has nearly finished its traverse
and is about to be stopped by the stop H5, when the latch drops or is drawn
(by means of a spring H attached to one end of it) against the projection H³
upon the slide (as shewn in dotted lines in Fig. 18), and thus the latch locks the
slide and prevents any rebound. The latch is unlocked or lifted out of its
latched position by a finger H* fixed upon the thread-layer-lifting-bar B7, which
in its upward movement acts against the head of a set screw H° (or other suitable
projection fixed or formed upon the latch), and thus the incline slide is liberated
for its return traverse. The thread-layer-lifting-bar B' is lifted by a rocking
shaft worked by a cam or other suitable well known method, and acting upon
rods attached to the thread-layer-lifting-bar in the same manner as is in ordinary
use for sinker-lifting bars. A sliding-locking-latch working in vertical guides
may obviously be substituted for the pivotted locking latch, and the lifting of the
latch to unlock it may be effected by a separate cam, or by another convenient
moving part of the machine.
In cases where the drawing across motion is obtained by the revolution of a
cylinder with helical projections or grooves actuating a pivotted lever, called
hereafter the drawing-across-lever, it is of advantage to provide for arresting the
motion of the lever at any time.
The sixth part of my Invention relates to means of effecting this by disengaging
the part which communicates the motion to the lever from the helices on the
cylinder, which part is hereafter called the half-moon-piece; Fig. 20, Sheet VI., is
a side view of the half-moon-piece and portions of adjacent parts, and Fig. 21 is a
front view thereof; I is a. cord or chain leading to the narrowing handle, or other
convenient attachment thereto; I' is the cylindrical projecting end of the half moon
piece 12; I³ is the drawing across lever; I, a portion of the cylinder with helical
projections; I' is a spring fixed to the drawing-across-lever for keeping the half-
moon-piece in position; 1º is a bracket for supporting the cylindrical projecting
end of the half moon piece. When the cord I is pulled in the direction of the
arrow I, the half moon piece is drawn away from the cylinder clear from the
projections on it, and the cylinder I will then revolve without moving the half
moon piece or the lever on which it is mounted, the drawing across motion being
thus arrested. The cord I (or a second cord attached to it) may be led by guide
pulleys or other convenient equivalent means to a handle in any other suitable
position in the machine, and the drawing-across-motion can then be arrested at any
time by the operator.
She seventh part of my Invention relates to an arrangement for guiding and
partly balancing the weight of bars required for welting and other similar purposes;
Figs. 25 and 26, Sheet VII., shew this arrangement; Fig. 25 is a part general end
view of a complete machine, and Fig. 26 is a part front view thereof; K is the
welding or other bar pivotted to arms K', K', by joints K2, which arms and joints
guide the welting hooks between the needles or on to the needle heads, admitting
of the usual requisite amount of lateral motion during different parts of the process
of making a welt. The arms K2 are pivotted to the arins of a rocking shaft K³,
which is arranged to rock upon its axes K. The arms K', K¹, are equal, as also
are the arms of the rocking shaft K³, thus the motion permitted to the bar K is
always parallel to the line of the needles. For welting the bar has a short arm K³
projecting downwards, which arm may have on its side a step or depression K
corresponding to the gauge of the machine; this step when required is brought by
means of the handle against a stop K' on the underside of the knocking-over bar
(as indicated by the dotted lines in Fig. 25), and when so brought definitely controls
the amount of lateral motion required. A counterweight K may be fixed, as
shewn, so as to keep the bar K up, as shewn in full lines, when not required for

page_text: welting. The bar K is shewn in dotted lines in one of its positions when making
a welt Bars for other purposes, such as for putting on rib-tops, may be guided.
in a similar manner, and for some classes of work the bars, whether welting bars
or picking up or putting on bars, may be guided in a similar manner, such bars
being (when required) arranged at the lower part of the machine instead of at the
upper part. This arrangement enables the operation of welting and other similar
processes to be performed with speed, accuracy, and facility even upon wide
machines comprising several divisions, and in such machines a number of welts
may be made simultaneously and at one operation, instead of, as hitherto, by a
separate operation for each division.
The eighth part of my Invention relates to an arrangement of a sliding frame
for carrying the coverers, and to a mode of actuating it by cams and by curved
inclines and parallel surfaces in such a manner as to impart any required nove-
ments to the coverers when narrowing the fabric. Figs. 27, 28, and 29, on
Sheet VIII. (in conjunction with others of the Drawings), shew the arrangement
for carrying out this part of my Invention. Fig. 27 is a part side view of one end
of a coverer slide bar and sliding frame and adjacent parts; Fig. 28 is a part front
view thereof; and Fig. 29 is a part plan. The sliding frame L carries the coverer-
slide-bar L³, which can rock upon centres in the usual well known manner, and on
the coverer slide bar are the usual well known coverer slides Ls. The sliding frame
and its attachments receive and communicate to the coverers the usual backward and
forward motion, this being effected by two cams L' (one at each end of the machine
upon the usual cam shaft) acting upon the two projections L³, one at each end of
the sliding frame. Suitably curved and shaped inclines L are attached to or
formed on the under surfaces of the sides of the sliding frame, and these inclinės
rest and slide upon the upper surfaces of the projections L7 (attached to the
knocking over bar or other convenient part of the machine), by which the sliding
framo and the coverers are raised or lowered at both ends as required as they pass
backwards and forwards. The sliding surfaces L' can (if required) be kept in
contact with the surfaces L7 by means of a spring Le attached to any convenient
part of the framing of the machine. The sliding frame carries on each side of it an
adjustable set screw L°; the heads or ends of these set screws work against parallel
guides Lo, which may be attached (one at each end of the machine) to the knocking
over bar or other convenient part of the machine; these guides, together with the
inclines L, guide the sliding frame accurately in the usual well known movements
required to be imparted to the coverers when narrowing, and the arrangement gives
greatly increased facilities for controlling and arranging all these movements in the
manner most suitable to each case. The elevation and depression of the points of
the coverers during their movements backwards and forwards can be controlled by
a lever L, which is attached to the coverer-slide bar, and its upper surface L¹ near
its end may slide under the surface L's of the lever L, which may be held upwards
by a spring L. The other end of the lever L" may be acted upon by a cam L16, so
formed as to elevate and depress the points of the coverers when required. Lis
a stop to prevent any overlift of the coverers.
'
"
The ninth part of my Invention relates to an arrangement for facilitating the
manipulation of what are well known as " picking up bars" or "putting on bars
by another and distinct use of the sliding frame before described as used for
narrowing. Figs. 27, 29, 30, and 31, on Sheet VIII. (in conjunction with others of
the Drawings) shew this arrangement; Fig. 30 is a part end view of this
arrangement; Fig. 31 is a part plan. When it is desired to "pick up" the loops
on the needles or "put on" another row of loops by a bar the sliding frame may
be drawn backwards away from the needles and the bar M filled with suitable
points placed in front of the coverer slide bar; the ends of the bar may be formed
into pivots M¹, which drop into hooks M² on the sliding frame. Projections M³ on
the sides of the sliding frame similar to the projections L' may be acted upon by
the cams L, which will thus impart the usual necessary backwards and forwards
notion to the bar. The under surfaces of the curved inclines Le may be extended,

page_text: as shewn at M, M*, so that they may slide on the projections L' when the sliding
frame is in position for being used for "picking up" or "putting on," and these
sliding surfaces may be shaped or curved to give any required upward and
downward motion to the "picking up bar" and its points, which motions can
by this method be different to the upwards and downwards motions for the
narrowing "points." The elevation and depression of the "points" can be regulated
by the handle M*.
The tenth part of my Invention relates to the arrangement of a sliding frame
for carrying what are well known as "needle bars," which sliding frame is actuated
by cams and inclines or curved surfaces in such a manner as to impart any required
movements to the needles when making web and narrowing. Figs. 32 and 33, on
Sheet VI. (in conjunction with others of the Drawings) shew this arrangement;
Fig. 32 is a part side view of one end of a sliding frame and needle bar with
adjacent parts; Fig. 33 is a plan of the same end of the sliding frame. The needle
cams O give the usual well known reciprocating motion to the needle bar by acting
on projections O¹ on the sliding frame 0%, on to which is pivotted the usual needle
bar or needle bars by the joints O³; part of the under surface at each of the front
ends of the sliding frame have suitably curved or shaped inclines O* formed on or
fixed to them, which inclines slide. on the upper surface of projections O" (which
may be formed upon or attached to the knocking over bar or to any other
convenient part of the machine), and thus can give any required upwards or
downwards movements to the pivots or joint pins of the needle bar or bars. The
back end of the sliding frame may be supported by brackets 06 carried from any
suitable part of the framing of the machine. Other cams 07 actuate the sliding
frame by other projections Os on the opposite side to the projections 0¹ when it is
required to give the needle bar the necessary motions for narrowing. There are
similar cams and projections from the sliding frame and curved inclines at the other
end of the machine to produce the required parallel movements of the needle bar
or bars.
The eleventh part of my Invention relates to a modified arrangement of the
sliding frame for the "needle bars." Figs. 34 and 35, on Sheet VI. (in conjunction
with others of the Drawings) shew this arrangement; Fig. 34 is a part side view
of one end of a sliding frame and needle bar with adjacent parts; Fig. 35 is a plan
of the same end of the sliding frame. The needle cams P give the usual
reciprocating motion to the needle bar by acting on projections PI on the sliding
frame P, which is attached at its front end to the usual needle bar or bars. Part
of the under surface of each of the sides of the sliding frame have suitably curved
or shaped inclines P* formed on or fixed to them, which inclines slide on the upper
surfaces of the stationary projections P5 and thus give any required inclinations to
the needle bar or bars and the needles. The sliding frame is worked by another
set of cams P in narrowing, as previously described.
The twelfth part of my Invention relates to an arrangement for moving the
sinker-incline upwards and downwards when required to perform the operation
well known 66
88 altering the stiffness:" Figs. 22, 23, and 24, on Sheet VI. (in
conjunction with others of the Drawings) shew this arrangement. Fig. 22 is a
transverse section of a sinker-incline with its adjacent parts, Fig. 23 is a front
view, and Fig. 24 is a part plan. N is a wedge fixed to one end of a short rod,
which rod has a screw thread N¹ cut upon its other end. Upon this screw is
mounted what is well known as a star wheel N³, which also forms the nut for
working the screwed rod N'. On turning the "star wheel" the wedge N will
either be forced backwards or forwards. If forwards, it pushes the sinker-incline N³
down; or if backwards, it allows the sinker incline to be lifted by the spring N
This arrangement gives great facility for "altering the stiffness" from time to time,
as may be required separately in each division from the front of the machine, such
alterations being easily made very small, and always of a definitely known amount,
having a fixed proportion to the movements of the "star-wheel."
The thirteenth part of my Invention relates to an arrangement for using what

page_text: are known as knocking-over-bits hooked at the upper end and sliding in grooves
in the face of the knocking-over-bar, so that the needles are supported by the
walls of the said grooves, and the hooks are formed in such a manner that in the
operation of narrowing the loops are pushed towards the heads of the needles by
the faces of the hooks when the loops are "picked up" by the coverers. Figs. 36,
37, 38, 39, and 40, Sheet IX. (in conjunction with others of the Drawings), shew
successive positions of the hooks relatively to the needles and coverers when
narrowing, and Fig. 41 is a section of part of the machine shewing the arrangement
of the parts. Q is one of the hooks which slide in grooves in the face of the
knocking-over-bar. These hooks may receive their usual well known movements
from a bar Q', which may be lifted and lowered by a rocking shaft worked by a
cam or other suitable well known method, and connected by rods Q³ to the bar Q¹
in a manner similar to that for working sinker lifting bars. By arranging the
hooks to slide in grooves in the knocking over bar whilst the needles rest on the
tops of the partitions between the grooves, the support for the needles is not
removed. The motions required for narrowing will be easily understood by
reference to Figs. 36 to 40 inclusive. Fig. 41 shews parts of Fig. 25 on a larger
scale, and Fig. 42, Sheet X., is a part end view of a complete machine.

Having thus described the nature of my Invention, and in what manner the
same is to be performed, I desire.it to be understood that I do not confine myself
to the exact details herein set forth, as such may be varied or modified without
departing from the principle thereof, but I claim as my improvements in knitting
machinery in so far as they may be used, either separately or in combination,-
First. The arrangement of thread-layer-slide or thread-layer slides hanging or
gripping (or both) upon a traversing tube or rod, which being caused to traverse
to and fro carries with it the slides by their frictional hold upon it, and which is
also an axis, round which any of the slides can be turned out of action, sub-
stantially as herein described with reference to Figs. 1, 2, 3, 4, and 5 of the
accompanying Drawings.
Second. In machines having several divisions, in each of which several thread
layer slides are used in certain portions of the work, the construction, connection,
and arrangements for stopping such sets of thread-layer slides, substantially as
herein described with reference to Figs. 1, 2, 6, 7, 8, 9, 10, 11, and 12 of the
accompanying Drawings.
Third. Constructing the drawing across pulleys with fingers pivotted on a point
within the periphery of the pulley in such a manner that these pivotted fingers
can recede, and thus at any required moment instantaneously (or, if desired, with
an amount of continued tension which can be regulated at pleasure) release what
is ordinarily known as the drawing across bob, and the end of the cord or belt for
drawing across the sinker incline slide, substantially as herein described with
reference to Figs. 13, 13, 14, 16, 16ª, 16b, 16º, 16ª, and 16º.
Fourth. The use (with the before mentioned drawing across pulley) of bob.
lifters for lifting the drawing across bobs off the periphery of the drawing across
pulley, so as to prevent them from being caught by the fingers and carried round
with the pulley, substantially as herein described with reference to Figs. 13, 15,
15%, and 16.
Fifth. The method of using a locking-latch pivotted (or sliding in guides) on
the incline-slide-bar lifted by and then acting against a projection formed upon or
rigidly attached to the incline-slide for the purpose of preventing any rebound of
the incline-slide when it is stopped at the end of its traverse, and liberating the
incline-slide when it is unlocked or unlatched by means of the thread-layer-lifting-
bar or by a cam or other convenient moving part of the machine, substantially as
herein described with reference to Figs. 17, 18, and 19.
Sixth. In cases where the drawing across motion is obtained by the revolution
of a cylinder with helical projections or grooves actuating a pivotted lever, the
method of arresting the lever at any part of its movement by disengaging the

page_text: part which communicates the motion to the lever from the helices on the cylinder,
substantially as herein described' with reference to Figs. 20 and 21.
Seventh. The method of guiding and partly or wholly balancing the weight of
bars required for welting and other similar purposes, which method enables the
operation of welting and other similar processes to be performed with speed,
accuracy, and facility even upon. wide machines comprising several divisions,
substantially as herein described with reference to Figs. 25 and 26.
Eighth. The arrangement of sliding-frame for carrying the coverers, and the
mode of actuating it by cams and by curved inclines and parallel surfaces in such
a manner as to impart any required movements to the coverers when narrowing
the fabric, substantially as herein described with reference to Figs. 27, 28,
and 29.
Ninth. The method of and arrangements for facilitating the manipulation of
what are well known as picking up bars or putting on bars by another and distinct
use of the sliding frame before referred to as used for narrowing, substantially as
herein described with reference to Figs. 27, 29, 30, and 31.
Tenth. The arrangement of sliding frame for carrying the needle bars, which
sliding frame is actuated by cams and inclines or curved surfaces in such a manner
as to impart any required movements to the needles when making web and
narrowing, substantially as herein described with reference to Figs. 32 and 33.
Eleventh. The arrangement of sliding frame carrying the "needle bars" modified
so as to dispense with the jointing of the bars to the sliding frame, the required
inclinations being given to the needles by suitably formed curved inclines or cams,
so as to determine the up and down movements of the sliding frame, substantially
as herein described with reference to Figs. 34 and 35.
Twelfth. The method of moving the sinker incline upwards and downwards
when required to perform the operation well known as "altering the stiffness" by
means of an arrangement of a wedge screw and "star wheel" combined, substan-
tially as herein described with reference to Figs. 22, 23, and 24.
Thirteenth. The method of using knocking-over-bits hooked at the upper end
and sliding in grooves in the face of the knocking-over-bar, so that the needles
are supported by the walls of the said grooves, and the hooks are formed in such
a manner that in the operation of narrowing, the loops are pushed towards the
heads of the needles by the face of the hooks when the loops are "picked up" by
the coverers, substantially as herein described with reference to Figs. 36, 37, 38, 39,
40, and 41.
In witness whereof, I, the said Arthur Paget, have hereunto set my hand
and seal this Third day of February in the wear of our Land One thousand
