Improvements in or relating to Straight Bar Knitting Machines.
We, WILLIAM HENRY BLACKBURN and EDWARD HOULDGATE, both of the Firm
of Blackburn & Houldgate, Woolpack Lane, Hosiery Manufacturers, and JOHN
DAVIES, of 2, Ridding Terrace, Wellington Street, Machinist, all in the City
of Nottingham, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in what is known as the fashioning
apparatus of straight bar knitting machines, that is the means for carrying
and operating the coverer points used for transferring loops in the process of
manufacturing fashioned garments, or parts of garments.
The present invention relates more particularly to apparatus for producing
seamless gores or pockets at any point in a garment or part of a garment
in the process of manufacture, simultaneously when required with narrowings
or widenings to form gussets or the like, at other points in the same piece of
fabric.
According to our invention we employ to each division of the machine, two
sets of coverer points, one on the right and one on the left of each division,
but as they are all identical in construction and arrangement, it will only be
necessary to describe one of them.
Each set of points is carried by a coverer box, which is divided at any con-
venient point in its length, the outer part relatively to the division being fixed
rigidly to the ordinary point bar, whilst the inner part is pivotted or hinged
to the said bar, so that it together with the portion of coverer points carried
thereby, may be turned up out of the way when required about the said pivot.
This is automatically effected by means that will hereinafter be described.
In connection with the coverer points described we employ two filling up
points, one hereinafter termed the inner, being placed on a vertical slide near
the inner edge of the binged part of the coverer box, and the other hereinafter
termed the intermediate, on a slide near the point of division, but in the fixed
part of the coverer box. Normally this filling up point is held out of action
by a stud on the hinged part of the coverer box and only comes into action when
the hinged part of the coverer box is raised, the inner filling up point being
raised out of action with the hinged part of the coverer box.
The filling up points when in action are operated in a well known manner
by an arrangement which is described in the Specification of Letters Patent
No. 10045 of the 18th of July 1887.
In making a gore or pocket we commence by putting one or more widenings
in say two successive courses, with a short interval of four or any other number
of needles between the said windings, and say one or more plain courses between

page_text: every two courses with widenings. This is continued until the required fullness
is obtained. Then we may commence to narrow again at once or make a few
plain courses and then commence to narrow until the original width is reached
again, the narrowings being preferably arranged in all respects the same as
the widenings.
This is effected in the following manner: -In commencing to make a gore, the
inner coverer point of the set is first adjusted at the point where the gore is to
be formed, they are then automatically brought down at the proper time during
the knitting of a course, and take the whole of the loops from the needles, from
this point to the selvedge, the coverer points are then racked outwards one needle
or more as required, then deliver the loops and rise clear.
This course is then completed and the next course commenced, the coverer
points are then shogged outwards say four or any other number of needles from
the widening in the previous course, are then brought down again and take all
the loops from this point to the selvedge. They are then racked outwards one
or more needles, deliver the loops and this course is then completed and one or
more plain courses knitted.
In narrowing to finish the gore, the same proceedure is followed, but the
coverer points are in this case racked inwards.
If it is desired to form say a gusset by widening near the selvedge,
or put in
narrowings simultaneously with the formation of the gores, this is effected as
follows.
After putting one or more widenings or narrowings in say two following courses
in the formation of a gore, the hinged part of the coverer box is turned up out
of the way together with the coverer point secured thereto, and widenings
or narrowings may now be made in the next course with the remaining coverer
points on the fixed part of the coverer box. These widenings or narrowings
will be put in at the point of division of the coverer box, and their distance from
the gore will be mainly regulated by the position of the point of division in the
coverer box.
In making the widening for the gore the inner filling up point is in action,
whilst in say widening to form a gusset, the intermediate filling up point will
come into operation.
The coverer boxes are connected to and operated by two point bars which are
carried in the usual manner, the coverer boxes on one side of each division of
the machine being connected to one point bar, whilst the corresponding boxes
on the other side of each division are connected to the other point bar in the
usual manner.
Each point bar is moved longitudinally to transfer the loops as described. by
independent arrangements placed at opposite ends of the machine, but as these
are identical in construction and operation, the following description which
applies to one, will also apply to the other.
Secured to the ordinary fashioning box or what is more commonly termed
the narrowing box, (which is provided with the usual stops for controlling the
thread carriers, and is mounted in guideways along which it is moved by a screw
in the usual manner), is a second shorter set of guideways placed parallel to
the former, in which is mounted a box hereinafter referred to as a supplementary
box. The guideways of the supplementary box are moved bodily with the
fashioning box, but in addition to this the supplementary box is moved along
its own guideways, by a second independent screw mounted in the said guide-
ways.
By means of this supplementary box we can readjust the position of the coverer
points relatively to the selvedge of the fabris after each widening or narrowing
effected by the fashioning box. This adjustment is required in the process of
forming a gore or the like in the manner hereinhetore described.
The supplementary box screw is rotated in either direction by means of a
rack wheel connected thɩreto by gearing, said rack wheel being actuated by one

page_text: of two pawls arranged respectively on each side of the rack wheel, but as the
rack wheel moves bodily with the supplementary box guideways, the said pawls
are of special construction.
Each pawl is comprised of a bar placed parallel to the axis of the rack wheel,
the said bar being in each case carried on preferably two arms pivotted to the
free end of one common lever. This lever is provided with an anti-friction
roller which engages with a cam on the main cam shaft, and thus transmits
motion to both pawls.
Between the pawls is a shield pivotted loosely on an extension of the rack
wheel axle, by a partial rotation of this shield either or both of the pawls may
be held out of action.
Connected to the shield is a long toothed pinion which is constantly in gear
with a toother quadrant, which is pivotted on a fixed axle secured to the
framing. This quadrant is connected to the controlling chain mechanism, and
by means of a series of studs on the chain of the latter, the position of the
shield is, through the arrangement described, rotarably adjusted to put the
requisite pawl into action at the required intervals.
The point bar is not directly connected to the supplementary box, but is con-
nected to a slide mounted on the supplementary box. This slide is so mounted
on the supplementary box that it is capable of a short reciprocating movement
relatively to the box and in the same direction as the traverse of the latter.
The slide described is provided at its ends with anti-friction rollers mounted
on vertical axles, between which is a cam lever which is also mounted on a
vertical axis secured to the supplementary box. This cam lever is provided at
its ends with cam profiles which engage with the antifriction rollers on the
slide, and by the reciprocation of the cam lever the slide is caused to move to
and fro relatively to the supplementary box.
This movement shogs the coverer points to produce the interval between the
widenings or narrowings in the same or following courses, in the process of
forming a gore or packet as previously described.
The cam lever is actuated by the following mechanism.
Placed parallel with the fashioning box guideways is what may be termed a
reciprocating wiper bar, this bar is mounted on the free ends of preferably two
arms, which latter are secured on a rocking shaft. This rocking shaft is carried
in bearings secured to the framing, and receives a constant rocking motion from
a cam on the main cam shaft.
This rocking motion causes the wiper bar to alternately approach and recede
from the supplementary box.
Connected to each end of the cam lever on the supplementary box is a link,
the free end of either of these links may be raised until it engages with the
wiper bar, and the movement of the latter will be thus imparted to the cam
lever.
It will be understood that if one of the cam lever links are raised the cam
lever will be moved about its pivot in one direction, if the other is raised,
its position will be reversed.
Each cam lever link is connected to the controlling chain mechanism, and each
link is raised by an independent series of studs placed on the controlling chain
at the requisite intervals. By means of this arrangement the coverer points
may be shogged alternately outwards and inwards, any number of needles
between two widenings or narrowings in the same course, or two following
courses.
The pivotted or hinged part of each coverer box is held down or raised as
previously described, by means of a rocking shaft mounted in bearings secured
to the point bar framing. This shaft is provided with a number of pairs of arms,
in the free ends of each pair of which is secured a rod placed parallel to the
rocking shaft; each of the latter engage in a slotter arm secured to the hinged
part of the corresponding coverer box.

page_text: By partially rotating the rocking shaft the whole of the hinged portions of the
coverer boxes may be raised or lowered, as required.
For this purpose the rocking shaft is connected to a cam lever which is
operated by either of two cams placed on the main cam shaft. The first of these
cams is adapted to follow the motion of the point bars and hold the coverer
boxes down, whilst the second raises the points clear of the needles at the time
they would under ordinary circumstances take the loops from the needles.
When fashioning with the whole of the coverer points in each coverer box in
action, the main cam shaft is moved longitudinally by a well known arrange-
ment in order to bring the necessary cams into action, and throw out the remainder.
This movement brings the first of the two cams previously referred to, into
peripheral contact with the anti-friction roller on the cam lever, and the hinged
parts of the coverer boxes are thus held down.
The second of the two cams is brought into action when it is required to
raise the hinged parts of the coverer boxes, by moving the anti-friction roller on
the cam lever laterally on its axis, simultaneously with the movement of the cam
shaft, but in the reverse direction. This is effected by the following arrange-
ment: Pivotted midway between its two extremes on a fixed axle secured to the
framing, is a lever, the lower end of which is connected to the main cam shaft, so
that the longitudinal movement of the latter in its bearing causes the upper end
of the said lever to move in the reverse direction. The free end of this lever
either hits or misses a cross bolt (according to the position of the latter), on a
longitudinal sliding bar or shaft provided, with a fork to engage with the anti-
friction roller of the cam lever previously referred to.
It thus follows that if the free end of the lever engages with the cross bolt,
the antifriction roller on the cam lever will receive a lateral motion in the reverse
direction to the cam shaft, and will be moved on to the third cam, and in this
case the hinged parts of the coverer boxes will be raised by the said cam, whilst
those in the fixed part are brought down to take the loops.
The cross bolt is connected to the controlling chain mechanism, and its
position is thus adjusted from time to time by a series of studs at the requisite
intervals on the controlling chain.
The movement above described is also used to bring a special cam into action
for operating the intermediate filling up points in each coverer box, which
although operated by the same mechanism as the inner filling up point, requires
a different cam motion, owing to the difference in the construction or shape of
the slides carrying the said points.
The controlling chain mechanism comprises a broad chain, on which the
necessary series of studs hereinbefore referred to, are secured in lines at different
points in its width, this chain is used in connection with any well known arrange-
ment for controlling the devices hereinbefore described.
cases
Instead of arranging the coverer box as described, we may in some
find it more convenient to use a coverer box with a fixed inner part and a pivotted
outer part, or a coverer box with a fixed middle part and both a pivotted inner
and outer part.

Improvements in or relating to Straight Bar Knitting Machines.
We, WILLIAM HENRY BLACKBURN and EDWARD HOULDGATE, both of the Firm
of Blackburn & Houldgate, Woolpack Lane, Hosiery Manufacturers, and JOHN

page_text: DAVIES, of 2, Ridding Terrace, Wellington Street, Machinist, all in the City
of Nottingham, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:―
This invention relates to improvements in what is known as the fashioning
apparatus of straight bar knitting machines, that is the means for carrying
and operating the coverer points used for transferring loops in the process of
manufacturing fashioned garments, or parts of garments.
The present invention relates more particularly to apparatus for producing
seamless gores or pockets, at any point in a garment or part of a garment
in the process of manufacture, simultaneously when required with narrowing
or widening to form gussets or the like, at other points in the same piece of
fabric.
The invention will be best understood by reference to the accompanying
drawings, in which
Fig. 1 is a vertical cross section, and
Fig. 2 a front elevation of the coverer point mechanism of one division of the
machine, arranged according to our invention.
Fig. 3 is a vertical cross section of the coverer point mechanism, showing
part of the points thrown out of action.
Fig. 4 is an end elevation, and
Fig. 5 a plan of the right-hand end of the machine, showing the fashioning
apparatus.
Fig. 6 is a front elevation, and
Fig. 7 a plan showing detail of the coverer box operating mechanism.
Fig. 8 is a front elevation showing detail of the supplementary fashioning box.
Figs. 1-2 and 3 are drawn to a larger scale than the remaining figures.
Like letters indicate like parts throughout the drawings.
According to our invention we employ to each division of the machine, two
set of coverer points A and A¹ (see Fig. 2) one set A on the left, and the other A¹
on the right, but as they are all carried by mechanism which is identical in con-
struction and arrangement, it will only be necessary to describe that of one set.
Each set of points A (see Figs. 12 and 3) is carried by a coverer box A2 A³,
which is divided at any convenient point A in its length. The outer part A³
of the coverer box is secured to the point bar C or C¹, whilst the inner part A²,
is hinged to the point bar, or pivotted at A5 to the outer part A3 as shown. The
inner part A2 of the coverer box may thus be raised about the said pivot as
shown in Fig. 3, in order to throw the coverer points which it carries, out of
action.
This is automatically effected by means that will hereinafter be described.
In connection with the set of coverer points described we employ two filling
up points, one being carried on a vertical slide D at the inner edge of the
inner part A2 of the coverer box, and the other on a slide 12 at the point of
division A, said slide D² being mounted in the part A³ of the coverer box.
Normally the slide D2 is held out of action by a stud 13, on the part A² of
the coverer box, engaging with a latch D on the slide D2, and the filling up
point which the said slide carries, only comes into action when the part A³
of the coverer box is raised, and the filling up point 11 is raised with it.
The slides D D2 of the filling up points when the latter are in action, are
operated in a well known_manner by an arrangement which is described in
the Specification of Letters Patent No. 10045 of the 18th of July 1887.
The upper end d of the slide D is however arranged to engage with the
underside of the operating bar D³, and is depressed by the said bar, and raised
by the spring 16 (see Fig. 2). On the contrary the upper end of the slide D²,
is arranged to engage with the upper side of the operating bar D5, and is raised
by said bar and depressed by the spring D7 (see Fig. 2).
With this arrangement it will be seen that the slide D2 may remain in its

page_text: normal position whilst the slide D is depressed by the bar D³, and that the
head of the slide D is moved clear of the operating bar D³ when the part A² of
the coverer box is raised, as shown in Fig. 2.
In order to make a gore or pocket, we only use one set of coverer points
arranged as described, and as there are two sets to each division of the machine,
we are able to make two gores or pockets simultaneously in one garment.
We make a gore or pocket by putting one or more widenings in say two
courses, with a short interval of four or any other number of needles between
the said widenings, and say one or more plain courses between every two courses
with widenings. This is continued until the required fulness is obtained. Then
we commence to narrow again at once, or make a few plain courses, and then
commence to narrow until the original width is reached again, the narrowings
being preferably arranged in all respects the same as the widenings.
This is effected in the following manner:--In commencing to make a gore
or pocket, the inner coverer point of the set is first adjusted at the point where
the gore is to be formed, they are then automatically brought down at the
proper time during the knitting of a course, and take the whole of the loops from
the needles, from this point to the selvedge. The coverer points are then racked
outwards one or more needles as required, then deliver the loops and rise clear.
This course is then completed and the next course commenced, the coverer
points are then shogged outwards, say four or any other number of needles from
the widening in the previous course, and then brought down again and take all
the loops from this point to the selvedge. They are then racked outwards one
or more needles, deliver the loops, and this course is completed and one or more
plain courses knitted.
The coverer points are shogged inwards again, to the point where the first
widening was finished, and the above course of operation followed until the
requisite fullness is obtained. In narrowing to finish the gore, the same pro-
ceedure is followed, but the coverer points are in this case racked inwards when
removing the loops.
If it is desired to form say a gusset by widening near the selvedge, or put in
narrowings simultaneously with the formation of a gore, this is effected as
follows.
After putting one or more widenings or narrowings in say two following
courses in the formation of a gore, the part A of the coverer box is turned up
into the position shown in Fig. 3, together with the coverer points secured thereto,
and widenings or narrowings may now be made in the next course with the
remaining points on the part 2 of the coverer box. These widenings or narrow-
ings will be put in at the point of division of the coverer box, and their
distance from the gore will be mainly regulated by the position of the point of
division in the coverer box.
In making widenings for the gore, the filling up point on the slide 1)
will be in action, whilst in the widening to form a gusset or the like, the filling
up point on the slide D2 will come into action.
The coverer boxes A2 A3 are connected to and operated by the two point
bars C C", which are carried in the usual manner, the coverer box on the left of
each division of the machine, being connected to the point bar C, and those on
the right of each division to the point bar C¹.
Each point bar C C¹ is moved longitudinally by an independent arrangement
placed at opposite ends of the machine, but as these are identical in construction
and operation, the following discription which applies to that on the right,
will also apply to the other.
Secured to the ordinary fashioning box E (see Figs. 45 and 8) or what is
more commonly termed the narrowing box, (which is provided with the usual
stops for controlling the thread carriers, and is mounted in a worm frame or
guideways E along which it is moved by a screw E2 in the usual manner) is a
second worm frame or set of guideways F placed parallel to the former, in

page_text: which is mounted a fashioning box F¹ hereinafter referred to as the supple-
mentary box.
The guideways F of the supplementary box F1 together with the latter are
moved bodily with the ordinary fashioning box E, but in addition to this the
supplementary box F¹ is moved along its own guideways, by a second independent
screw, or as shown by a worm Fon a shaft 3, which latter is mounted in
bearings Fin or secured to the guideways F. The worm F engages with a
toothed rack F on the box F¹.
By means of the supplementary fashioning box F, we can adjust the position
of the coverer points relatively to the selvedge of the fabric, after each widening
or narrowing effected by the fashioning box E. This adjustment is required
in the process of forming a gore or the like in the manner hereinbefore described.
The worm F2 for moving the supplemantary narrowing box F', is rotated in
either directions by means of a rack wheel G, secured on the worm shaft 13.
This rack wheel is actuated by one or two pawls arranged respectively one on
each side of the rack wheel, but as the rack wheel G moves bodily with the guide-
ways F, the said pawls are of special construction.
Each pawl is comprised of a bar G' and the said bars are each carried by pre-
ferably two arms G2 pivotted to the free end of a double lever G. This lever G
is pivotted at G+, and is provided with an anti-friction roller G5 (see Fig. 4),
which is in peripheral contact with a cam G on the main shaft K, and thus
transmits motion to both pawls.
The rack wheel G is normally masked by a shield H, which is mounted loosely
on an extension of the worm shaft F3, and thus holds both pawls G out of
action, but by a partial rotation of the said shield, either of them may be brought
into action.
Connected to the shield H is a long toothed pinion H¹ (see Figs. 5 and 8)
which is constantly in gear with a toothed quadrant H2, which latter is pivotted
on a fixed axle H in a bracket H*, secured to the guideways E of the ordinary
fashioning box.
This quadrant H2, is connected to the controlling chain mechanism, by a
link H (see Figs. 4 and 5), T shaped lever He mounted on the shaft J, link H7,
arm H8, and shaft H, and by means of a series of studs on the controlling chain,
the position of the shield H is adjusted to put the requisite pawls G into action
at the required intervals.
The lower part of the lever He is formed with a slot Ho (see Fig. 4) so that
the point of connection of the link H may be moved from one end to the other,
and thus from one side of the fulcrum to the other, in order to reverse the direc-
tion in which the shield H is moved. The position of the point of attachment
of the link is changed when changing from widening to narrowing, or vice-versa,
as in the one case the same pawl is always put into action, and in the other case,
the other or opposite pawl is always employed.
The point bar is not directly connected to the supplementary fashioning
box F but is connected to a slide I (see Figs. 45 and 8) mounted on or in
the said box. This slide I is so mounted that it is capable of a short reciprocating
movement relatively to the box, and parallel to the movement of the latter.
The slide I is provided at its ends with anti-friction rollers I between which
is a reciprocating cam I which is pivotted at 13 to the box. This cam I2 is
provided with two cam profiles, which engages with the anti-friction rollers I¹
on the slide, and by reciprocating the cam 12 the slide I is caused to move to
and fro relatively to the supplementary box.
This movement shogs the coverer points to produce the interval between the
widening or narrowings in the same or following courses, in the process of
forming a gore or pocket as previously described.
The slide I is provided with a horn It (see Figs. 4 and 5) which engages with
brackets I on the point bar (". and thus any movement of the latter is communi-
cated to the former.

page_text: The cam 12 is actuated, in order to shog the slide I at the requisite intervals,
and in the requisite direction, by the following a.angement.
Placed parallel with the fashioning box guideways is what may be termed a
reciprocating wiper bar J (see Figs. 4 and 5), this bar is mounted on arms J1
secured to the rocking shaft J, and the latter is carried in bearings J3 secured
to the framing of the machine.
This rocking shaft J2 is actuated by a cam J* (see Fig. 4) on the main shaft K,
through a cam lever J³ provided with an anti-friction roller in contact with the
cam, an arm J6 on the shaft J2, and a link J7 for connecting the arm Je to the
cam lever J³.
Connected to each side of the pivot of the cam 12 are links I Iº (see Figs.
and 5), the free ends of either of which may be raised until it engages with the
wiper bar J, and the movement of the latter will be thus imparted to the
cam 12.
It will be understood that if one of the links I be raised the cam 12 will be
moved about its pivot in one direction, if the other be raised it will be moved
in the reverse direction.
Each cam link I is connected to the controlling chain mechanism, and is raised
by an independent series of studs placed on the controlling chain at the requisite
points. By this means the coverer points may be shogged alternately outwards
and inwards, any number of needles between two widenings or narrowings in
the same course, or two following courses.
Each link I is connected to the controlling chain mechanism, by independent
shaft L L each provided with two arms L', in the free ends of which are
secured rods L2 L2. Mounted on each rod L2 is the lower end of a connecting
rod L3 the upper end of which is connected to the respective link I®. As the
fashioning box moves inwards or outwards, the connecting rods L³ move along
their respective rods L². The pivotted or binged parts A2 (see Figs. 12 and 3)
of each coverer box is held down or raised as previously described, by means of
a rocking shaft M mounted in bearings M¹ secured or formed on the point bar
framing. This shaft M is provided with a pair of arms M³, and a rod M
in the said arms, to each coverer box. Each rod M engages in a slotted arm M³
which is secured to the hinged part 2 of the corresponding coverer box.
By partially rotating the shaft M, the parts A2 of the whole of the coverer
boxes may be raised as shown in Fig. 3, or lowerer into their working position
as shown in Figs. 1 and 2, as required.
For this purpose the rocking shaft M is connected by an armi M, and link M7
to a cam lever M8, (see Figs. 46 and 7). This lever is actuated by one of two
cams N N' (see Fig. 6) on the cam shaft K, said cams being placed at one
side of a plain dise N2.
The cam N is adapted to follow the motion of the point bars and hold the
parts of the coverer boxes down, whilst the cam N is adapted to raise the
parts A2 of the coverer boxes, and raises the points attached thereto clear of
the needles, at the time they would under ordinary circumstances take the
loops from the needles.
When fashioning with the whole of the coverer points in each coverer box
in action the main cam shaft K is moved longitudinally to the right by the
usual arrangement, in order to bring the necessary cams into action, and throw
out the remainder.
This movement brings the cam N into peripheral contact with the anti-friction
rollers M on the cam lever M, and the parts A² of the coverer boxes are thus
held down.
The cam is brought into action by moving the anti-friction roller M
laterally on its axle M10, simultaneously with the movement of the cam shaft K,
but in the reverse direction.
This is effected by the following arrangement:--
Pivotted on a bracket () secured to the framing is a lever ()¹ (see Figs. 6 and 7),

page_text: the lower end of which is provided with an anti-friction roller 02 which engages
with bosses 03 on the cam shaft K, so that the longitudinal movement of the
latter to the right, causes the upper end of the lever to move in the
reverse direction, or to the left. The upper end 0* of the lever either hits or
misses a sliding cross bolt P which is carried in guideways P³ on a longitudinally
sliding bar P, which latter is carried in guideways P and is provided with a
fork P, to engage with the anti-friction roller M of the cam lever Ms.
The sliding cross bolt P is provided with a gap P (see Fig. 7) which the
end 0 of the lever normally enters, but if the bolt P is moved, the end 0*
of the lever engages with the said bolt, and the bar and anti-friction roller M
are moved by the lever ()' in the reverse direction to the cam shaft, and the
roller M is thus moved on to the cam X. In this case the parts A² of the
coverer boxes are raised by the said cam, when those in the fixed parts A³ are
brought down to take the loops.
The cross bolt P is connected to the controlling chain mechanism, and its
position is thus adjusted from time to time, by a series of studs placed at the
requisite intervals on the controlling chain.
The movement above described is also used to bring a special cam into action
for operating the intermediate filling up points in each coverer box, which
although operated by the same mechanism as the inner filling up point, requires
a different cam motion, owing to the difference in the construction or shape of
the slides carrying the said points.
For this purpose the bar P is provided with a second fork, which engages
with the anti-friction roller of the filling up point cam.
The controlling chain mechanism comprises a broad chain, on which the
necessary series of studs hereinbefore referred to, are secured in lines at different
points in its width, this chain is used in connection with any well known arrange-
ment for controlling the devices hereinbefore described.
Instead of arranging the coverer box as described, we may in some cases find
it more convenient to use a coverer box with a hinged or pivotted outer part,
or a fixed middle part, and both a pivotted inner and outer part.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In a straight bar knitting machine automatically raising and lowering
hinged or pivotted parts A2 of the coverer point boxes substantially as and for
the purpose described.
2. In a straight bar knitting machine having the combination with ordinary
fashioning box E of a supplementary fashioning box such as mounted in
guideways such as F secured to the box E so that the movement of the latter is
imparted to the box F a screw or worm for traversing the box along the
guideways F, providing a ratchet wheel G pawls G¹ shield such as H connected
to a pinion H and quadrant H2 connected to the controlling chain mechanism
substantially as and for the purpose described.
3. In a straight bar knitting machine the combination with a slide such as
I, of a cam such as 12 links Is I connected to the controlling chain mechanism
and a reciprocating wiper bar such as J substantially as described.
4. In a straight bar knitting machine the combination with the hinged or
pivotted part of a coverer box A2 of a shaft M armis M³ on the said shaft rods M
