Town and County of the Town of Nottingham and JOHN GROVES of 4 Burton Street
Loughborough in the County of Leicester, Manager and JAMES WHATNALL of
27 School Street Loughborough aforesaid, Mechanic both in the employment of the
said Nottingham Manufacturing Company Limited do hereby declare the nature of
this invention to be as follows:-
This invention has reference to the class of knitting machinery known as Cotton's
knitting machines.
The object of the invention is to produce automatically on a Cotton's machine
(described in the specification of Letters Patent granted to William Cotton, dated 25th
February 1874 No. 7.13) rib tops to knitted fabric such as pants half hose, shirts and
vests producing the slack course laying the splicing thread and forming the welt
by means of peculiarly formed combined cam surfaces operating suitable trucks or
bowls which enables the cam shaft to be shogged in one direction and then in the
opposite direction from off on to the ordinary working cam surface so as to attain
greater accommodation for production of longer or shorter loops and effecting the
splicing and welting as desired.
On the main shaft of the machine is mounted the ordinary toothed gearing wheel
for operating the drawing gear for giving motion to the loop forming parts and jack
sinkers and this toothed gearing we apply by means of a fin or key on the axis
engaging in a slot in the pinion strung on that main axis instead of by a clutch so
that the pinion is always in gear the pinion being retained in its relative position
by a fixed fork clasping a circular slot in the wheel collar. Also parts for dividing
and sinking the loop are provided.
For laying in the slack course we provide on the end of the main shaft a cam which
operates a bowl which is carried on a lever armi centred to the framing and at its other
end carrying clawkers or drivers which respectively engage separate sets of ratchet
teeth on a rib top wheel which also is formed with suitable cam surfaces for actuating
by means of a projection thereon an arm carrying a link connected to an arm which
whilst it is rigidly held in bearings from the framing so as to rock a changing shaft
which shaft is capable of sliding in those bearings, and the rocking of this shaft
moves a projection or finger thereon into and out of engagement with one or other
forked or recessed part formed on each thread carrier bar.

page_text: These thread carriers as their bars are thus engaged and actuated in turn are
traversed across the work by means of a friction box on the changing shaft engaging
that shaft and traversing as such friction box is moved by an arm operating it from
the slur box tie bar.
The necessary cams respectively are mounted on this main axis for actuating the
countershaft for moving the parts for regulating the slackness and stiffness of the
courses-for raising the catch bar-for actuating the needle bar when pressing-for
working the slide for knocking over the machine work, for working the frame needle
bar in knocking over and for the catch bar.
The principal cams are cach constructed with distinct and different cam surfaces
or paths along which the truck travels in turn as the axis is shogged or the truck
shifted.
The cam for effecting the shogging motion for shogging the cam shaft is con-
structed with two faces each carrying two heights of rising surfaces adapted to be
engaged with a truck carried on a spring arm from a rocking shaft as operated by
rib top wheel.
The thread carriers instead of being mounted and operated as ordinarily from the
slur bar, are according to this invention carried in arms from the head bar with
capability of being moved into and out of operation as required and as already
referred to by means of a friction box or engagement and a finger or projection on the
carrier slide without the great friction of the ordinary arrangement wherein the
carriers are merely stopped off and the friction of the bars passing through
the stationary carriers continues.
A rod or shaft connected with the drawing slide engages a centred lever arm
which engages a clawker which racks into the smaller teeth on the rack of rib top
wheel the end of this lever being formed to catch against the rod or shaft attached
to the drawing slide is by the movement of this rod or shaft caused to throw the
clawker out of engagement with the ratchet teeth for every other movement of the
slide.
For the regulation of the "slackness" or "stiffness" of the courses-either the
ordinary courses, the slack course or the courses in the welt-without interfering
with the other parts of the machine we provide a small counter-shaft and a lever
engaging stops supposing-say, three in number to be used carried adjustably
on the presser lever, one or the other stop meeting the counter shaft lever arm as their
position is regulated for the purpose.
Or, this relative position of the lever arm and the stops engaging it may be reversed
by placing the adjustable stops on the moving part and their abutting part on the
presser lever.
The width of the work being made is arranged and regulated by means of a worm
operated by a handle wheel or like part engaging a sliding guide or block which
carries stops which regulate the extent of motion of the carrier rods aided by a guage
plate marked accordingly.
The operations we effect with great reduction in the weight in the parts of the
machine, with simplification of construction and operation, avoidance of friction in the
ovements of the thread carriers and of the use of springs for effecting the return of
the trucks from one position of operation to the other.
According to one modification as applied to a Cotton's frame instead of using cau
surfaces working with trucks said cams having three surfaces on which the trucks
alternatively work for effecting shogging in one or the other direction, the com-
bined cam may be made with two surfaces and the trucks may be shifted from the
ratchet wheel.

invention and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
This invention has reference to the class of knitting machinery known in the trade
as Cotton's knitting machines, and to a modification of such machinery as is described
in the Specification of Letters Patent granted to William Cotton, dated 25th February
1874 No. 713. The object of the invention is to produce automatically on a Cotton's
machine rib tops to such knitted fabrics as pants, half-hose, shirts and vests; producing
the slack course, laying the splicing thread and forming the welt by means of peculiarly
formed combinations of cam surfaces adapted to operate suitable trucks or bowls by
means of which the cam shaft is enabled to be shogged first in one direction and then
in the opposite direction first from off and then onto the ordinary working cam surface
so as thereby to attain greater accommodation for the production of longer or shorter

a is the main shaft of the machine to which motion is communicated by means of
a fast pulley driven by band and provided with a loose pulley in the ordinary
manner, but not shown. On this shaft a is mounted the ordinary toothed gearing
wheel (see Figures 2A and 6) which engages with the correspondingly toothed
wheel &, mounted on an axis 62 carried in bearings 63 affixed to the main framing X.
On the opposite end of the shaft 62 is mounted the cam c, which in its rotation presses
the slide bar d to and fro, by its operation on the pulleys d'affixed thereto and
these movements of this bar d'are by the rod d² conveyed to the lever e (see Figures 3
and 26) by the end d³ of the rod d² pressing down the end e of the arm e and raising
the opposite end e carrying the pin e³ which pin raises the clawker e¹ out of engage-
ment with the teeth f2 of the wheel (see Figure 2 C).
The extent of motion of the
lever e is regulated by an adjustable stop e (see Figure 3) carried on a bracket from
the main fraiming X. The wheel b is applied on the shaft a, so that, whilst the shaft
may be moved endwise carrying with it endwise the various change cams hereinafter
described, the wheel & itself does not slide with the shaft a although it turns with it by
means of a fin a' on the shaft a engaging in a corresponding recess in the wheel b
(see Figure 6) said wheel being held by the fixed fork g clasping and holding from
lateral movement the circular slot on the boss g. Motion to and fro for operating
the usual parts for effecting the dividing and sinking of the loops is conveyed thereto
from the slide bar d by an arm not shewn in usual manner. The loop forming parts
and jack sinkers also being of the ordinary description.

page_text: For laying in the slack course the cam (see Figures 2 C and 3) is provided on the
end of the main shaft a, which cam operates a bowl i carried on a lever arm centred
at to the main framing X, and carrying pivotted to it at e the clawker e¹ which
engages the teeth 2 of the wheel, it also carries the clawker pivoted at to
engage the teeth of the same wheel f. These clawkers e and j respectively rotate
the wheel for effecting the shogging of the main shaft a and operate the knocking
over plate (see Figure 1) as hereinafter described. To the rim 3 of the wheel fare
affixed plates forming a cam surface which acts on to lift and lower the pro-
jection of the arm k which arm is pivoted to the main framing at k². This arm
carries a link connected to the short arm by pin joint. This arm is held in
bearings from the main bar u, so as to be capable when operated of rocking a
changing shaft supported in these bearings with capability of sliding endwise
therein as the projection ¹ on the arm k is raised or lowered by the cam surface ³
on the wheel. The arm k is constantly drawn towards the surface by
spring 46.
The rocking of the shaft 7 shifts a finger 12 borne thereby into and out of engage-
ment with one or other of the forked recesses m, n, o formed on the ends of the
thread carrier bars m², n', o¹ respectively as those bars are required to act.
The plates affixed to the rim of the wheel fare used for ordinary working,
when only the thread carriers n² and o² are in use, but when, as for "striping" the
carrier m² is required to act the plates are replaced by, other similar plates of
greater height thus giving greater extent of movement to the rocking shaft and
thereby to the finger las in the ordinary machines with horizontal needles.
The thread carriers m², n², o² are alternatively traversed across the work as their
respective bars are engaged and actuated in turn by the friction box 13 engaging the
changing shaft as such friction box 13 is moved by the fork 15 on the end of the
arm engaging with a projection on the friction box 13. The arm affixed to
the slur box p receives its motion from the slur box tie bar p².
The thread carriers m², n², o² instead of being mounted and operated as ordinarily
from the slur box are carried in arms m¹, n¹, o¹ supported in brackets u¹ from the
head bar with capability of being moved into and out of operation as required and
as above referred to.
The width of the work being made is arranged and regulated by means of a worm a
operated by a handle wheel a¹ engaging a sliding box which carries adjustable
stops, which regulate the extent of motion of the carrier bars m³, n', o¹
respectively.
On the main shaft a is mounted the triple cam which gives motion to a bowl q
(see Figures 2B, 13 and 13") on the lever arm 2 carried by a rocking shaft which
shaft also has affixed thereto lever arms 9. From the arms and project studs
which are each taken into by a notch formed on each handle rod 76 which have
handles their inner ends being connected by pin joints 28 to the ends of the
arms q, by which means the needle bar q is operated for the tilting motion for
pressing.
.13
To the lower end of the arm is affixed a bracket carrying adjustable
stops, 33, which engage with the lever arm carried on the rocking shaft »¹
and thereby the slackness or stiffness of the courses may be regulated. When no
tilting or pressing motion is required the lever arm rises, being actuated by the
cam surface 2, of the cam 4 and the cam surface 5 of the cam acts upon the
bowl q pressing the arm 2 with the adjustable stops outwards and thus allowing the
arm to come in contact with the adjustable stop g (see Figure 13ª). For ordinary
pressing motion this bowl q' is acted upon by the cam q. When, however during
the drawing action of any course or part course or when it may be desired to throw
in a splicing thread the length of the loops for the time obtained in the pressing may
be desired to be increased. This can be effected by increasing for the time the extent
of such pressing motion to the needle bar 7 (sec Figure 1) by causing the lever
aruto rise being actuated by the cam surface 3 of the cam 7, and the cam surface 6
of the cam 9 pressing the arm q² outwards allows the arm r to engage with the

page_text: stop g. For the stiff course the arm r is only slightly raised by the cam surface 1 of
the cam, and the arm q² being, by the cam surface 4 of the cam , pressed
sufficiently outwards the arm engages with the stop q¹³. The rocking motion to
the shaft is imparted by a bowl (see Figures 2A and 25) carried by an arm 7³
resting on the cain surface on the main shaft a.
The needle bar q is operated for its lifting motion by a cam q¹ (see Figures 1
and 2 B) acting upon bowls q mounted on arms q affixed to the rocking shaft q
717
which shaft also has affixed to it arms q which by pin joints q" are connected to the
bar g.
18
The to and fro motion to the catch-bar s is obtained by arms s' (see Figure 1)
therefrom being attached by pin joints to the end of the arm affixed to the
rocking shafts, supported to rock in fixed bearings from the main framing X and
having applied to it other arms so carrying bowls acted upon by the cams. The
lifting motion to the catch bars is effected by a bowl from an arm on the shaft 8
operated by a cam on the main shaft a in the ordinary manner.
The machine needle bar t is operated for its to and fro motion by cams t¹ (see
Figures 2 C and 5) acting on bowls 2 carried by arms t3 affixed to a rocking shaft t*,
on which are also affixed other arms & connected by pin joints to arms t from the
machine needle bar t. The lifting motion to the needle bar is effected by cams t
(see Figure 5) acting on bowls to carried by arms to rocking on axes t¹¹ being con-
nected by pin joints t¹ to rods ¹³ connected by pin joints to the plate t bolted to
the plate to, which plate is supported with capability of sliding vertically on the face
of the main bar u. This plate carries other plates 17 (see Figure 1) the
upper ends of which are turned over to receive the arms t carrying the needle
bar t.
The front end of the knocking over plate v (see Figure 1) rests on a fixed
projection, the to and fro motion being imparted by cams 2 acting on bowls 3
carried by lever arms affixed to the rocking shaft which is supported to rock in
fixed bearings and has applied to it other arms the upper ends of which are by pin
joints connected to the arms from the plate .
The principal cams on the main shaft à are each constructed with distinct and
different cam surfaces along which their respective bowls travel as the shaft is shogged
or the bowl shifted.
The cam (see Figures 10, 11, 23 and 24) for effecting the shogging motion for
shogging the cam shaft a is constructed in two parts with two faces each carrying two
heights of rising surfaces to¹ and w², w³ and w* respectively and is operated from the
rib top wheel by a nose piece w (see Figures 4, 10 and 12) affixed to an arm w
connected by link w' and pin joints, to a short arm to affixed to a rocking shaft 10
supported in bearings on the main framing X. The arm w at its other end is
connected by pivot joint to a bracket secured to the framing X.
The shaft lo carries the arm well and the bowl w¹. The nose piece w is pressed to
the rim by the spring w¹³ connected at one end to the main framing and at its
other end to the lower pin w³. As the wheel rotates the notch (see Figure 4) in
the rim is engaged by the nose piece 10 entering it thereby rocking the shaft w.0
and moving the arm and its bowl 2012 inward so as to be acted upon by the cam
course and thereby shogging the shaft a to the left hand.
The rocking movement of the shaft 10 is regulated by its having affixed to it an
arm which comes in contact with an adjustable stop w supported from the main
framing (see also Figures 5 and 10). As the wheelf is further rotated the nose
piece is disengaged from the notch fo and again presses on the rim f4, the bowl w
being thereby borne outwards engages with the surface w³ thus causing the shaft a
to assume its ordinary position. When however the wheel further rotates the nose
piece w comes in contact with a projection " on the rim and this nose piece
is depressed and the shaft w¹ and spring arm thereby rocked outwards causing
the bow to engage with the cam surface w₁ of the cam w, the shaft a thereby
being shogged towards the right hand and as the wheel ƒ further rotates, the nose

page_text: piece again travels on the plain surface f*, the bowl w¹ again moving inward and
engaging with the cam surface w¹.
The bowl acted upon by the cam² (see Figures 7 and 9), for giving the to and
fro motion to the knocking over plate (see Figure 1) in making welt is shifted
from off or onto the one or other of the two cam surfaces by a projection 8 (shewn
full size Figure 14) on the rim of the wheel f, as that wheel is rotated by the
clawkers e or j, coming in contact with a nose piece 8 (shewn full size Figure 15)
affixed to an arm joined by a pin joint 10 to the main framing X, and pushing it
towards the left thereby causing a rod held in bearings on the main framing and
connected by a pin joint to the arm and having a forked arm ¹³ affixed thereto
engaging with the bowl to move in a corresponding direction and shift that bowl
off or on to another of the cam surfaces of the cam v². A stop is secured to the
main framing X and prevents the arm from falling too far forward so that
the bowl is kept free from the cam when it is not necessary that it should be acted
upon thereby, thus preventing friction when the bowl is shogged. The wheel f
being further rotated the projection becomes disengaged from the nose piece
which is borne towards the face of the wheel by the spring 12 attached by a collar
to the rod at one end and at its other end to the main framing.
The wheel is rotated on its axis by the clawkers e and respectively according as
slow or fast motion is required, the teeth f2 engaged by the clawker e being finer
than the teeth engaged by the clawker j. The clawker e rotates the wheel at
alternate courses but the clawker only acting intermittently as already described
being prevented from engaging with the teeth fat certain intervals by small plates 10
on the rim of the wheel on which the teeth f¹ are, thereby forming a cam
surface.
The various bowls as s, are borne to their cams, as s³, on the main shaft a
by springs applied to their respective levers in the ordinary manner as shewn in the
drawings.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is.
