Improvements in Automatic Knitting Machines.
We, ROBERT WALTER SCOTT, and Louis NAPOLEON DEVON WILLIAMS,
both of 2079 East Cumberland Street, in the City of Philadelphia, State of
Pennsylvania, United States of America, Manufacturers of Knitting Machinery,
do hereby declare the nature of this invention to be as follows:
Our present invention comprises certain improvements in the knitting machine for
which we obtained Letters Patent No. 1240 dated January 23rd 1890, our present
improvements comprising certain modifications or elaborations in the detailed
construction of the machine with the general view of rendering the same more
effective in its action.
Our improvements can be summarized generally under the following heads :-
1st. Certain improvements in the cams which act upon the bits of the needles
during the knitting operation with the view of rendering such cams automatic in
action and preventing injury to cams and needles, and also to provide for readily
adjusting such elements of the cam mechanism as become worn in use.
2ndly. Improvements in the mechanism for operating the presser plates which
move the needles into action.
3rdly. Certain supplementary pressers for throwing all of the fashioning needles
into action for one or more courses when the narrowing operation has been
completed and before the widening operation begins.
4thly. Certain trippers for effecting the automatic movement of the cam which
throws the needles into operative position in making plain tubular work and for
effecting the shifting of the clutch in changing from round-and-round to to-and-fro
knitting and in stopping the machine when the work is completed, and
5thly. A special form of clutch whereby the machine is always caused to start in
the proper direction in commencing the to-and-fro movement.
We will describe these various improvements in the order enumerated.
The present machine has two side cams, each of which serves to lift the needles
when traversing in one direction, and to depress the needles when traversing in the
opposite direction, and between these two side cams and above the same is pivoted a
swinging toe cam which can move into contact with either side cam so that the bits
of the needles rising over one cam are properly directed to the drawing down face
of the other cam, and are prevented from coming in contact with the corner of said
cam so as to break or otherwise injure the needles or other parts of the machine.
The end cams which lift the needles to the inoperative position are not pivoted
as in the former machine but are fixed, and between these end cams and the side
cams before referred to are sliding cams which can be moved in-one direction or the
other by contact with the bits of the needles. When either of these sliding cams is
moved towards the lifter cam it is stopped by contact therewith and serves to direct
the needles from the side cam up to the lifter cam, but when said sliding cam is
moved away from said lifter cam it permits the bits of the needles to pass under
said lifter cam so that they will be acted upon by the advancing side cam.
The cam which, in producing plain tubular work, acts upon the bits of the
needles so as to restore the latter to operative position, after they have been raised
to inoperative position by the final lift cam, is mounted upon a spring which tends
to retract the cam and render it inoperative, but said cam is acted upon by a lever
which in turn is under the influence of certain operating devices hereinafter to be
referred to, so that said supplementary drawing down cam is thrown into and out of
action at the proper times, that is to say, it is thrown into action in changing from

page_text: to-and-fro to round-and-round knitting, and out of action in changing from round-
and-round to to-and-fro knitting.
The lifter cams are carried by stems mounted in brackets on the cam cylinder,
and these cams are much deeper than the amount of projection of the same into the
cam cylinder for acting on the needles, so that when the inner or acting end of the
cam becomes worn, the worn portion can be ground off and the cain projected
further into the cylinder so as to bring a new surface into play.
The presser plates are mounted in a vibrating frame as in the former machine,
and have toothed segments meshing with spur wheels carried by short vertical
shafts on said frame, but these shafts are operated in a manner different from that
heretofore adopted, that is to say, each shaft has a worm wheel which meshes with
a worm carried by a transverse shaft mounted in bearings on the vibrated frame, and
this transverse shaft has at one end a spur wheel meshing with a large spur pinion
loosely mounted on the axial shaft of the vibrated frame. If this spur pinion is
held stationary while the vibrated frame is rising and is permitted to turn loosely
when said frame is descending, the meshing therewith of the spur wheel of the
transverse shaft during the rising movement will cause said spur wheel to turn
in one direction, while if the spur pinion is held stationary during the down-
ward movement of the vibrated frame, and is permitted to turn loosely on the
upward movement, the spur wheel will be caused to turn in the contrary direction,
hence the transverse shaft and its worms can be caused to turn in one direction or
the other; depending upon whether the spur pinion is locked against movement in
one direction or in the other.
This locking of the spur pinion is effected by providing the hub of the same with
two ratchet wheels one right handed and the other left handed, and each of these
ratchet wheels is provided with a retaining pawl, that for one wheel serving to
prevent forward movement, and that for the other wheel serving to prevent back-
ward movement.
These pawls are under control of a pattern chain so that when one is in action,
the other is held out of action, hence, the spur pinion can be locked against forward
movement with the vibrating frame, or against backward movement with the same,
as required.
The worm wheels on the transverse shaft are so constructed as to act alternately,
so that movement is imparted alternately to the presser plates of the vibrating
frame.
On the vibrating frame are mounted supplementary segmental presser plates
which are sufficient in extent to cover all the fashioning needles on cach side of the
machine, that is to say, they cover the needles extending from the innermost point
in the narrowing to the outer ends of the fashioning set. so that, after the main
presser plates have been contracted to their full extent and the full narrowing of
the web has been effected, these supplementary plates may be brought into
operation for one or more courses, so as to form a band of full width in the centre
of the bulge or pocket which is being knitted.
These plates may be loosely pivoted to the vibrating frame so that under ordinary
circumstances they are free to rise and fall, and hence have no depressing effect
upon the needles beneath them, but when the main presser plates have been fully
retracted, pins or projections on said presser plates or on their segmental_racks
engage with like pins or projections on the supplementary presser plates and thus
lock the latter in the depressed position and cause them to act upon the needles so
long as they are thus locked, the movements of the main presser plates in com-
mencing the widening operation causing the disengagement of the pins or projections
and thus again freeing the supplementary presser plates.
Instead of this plan, however, the supplementary presser plates may be carried
by a special frame or by a pair of levers acted upon by cam disks, the movement of
which is controlled by gearing under the influence of a pattern chain so as to
provide for the operation of said supplementary presser plates at the proper times.
The lever which acts upon the supplementary drawing down cam so as to press

page_text: the same inward for action during round-and-round knitting, has two arms and
when changing from round-and-round knitting to to-and-fro knitting, one of the
arns of this lever is acted upon by a pin carried by a pivoted arm, which is
connected to the pawl acting on one of the ratchets on the hub of the spur pinion
which operates the gearing for moving the presser plates.
When this pawl is raised out of action therefore the pin on the arm connected
with the pawl acts upon the lever which controls the drawing down cam and moves
said lever so as to permit the cam to be withdrawn from action by its spring, and
this same movement of the lever causes a toe upon the same to act upon a lever
which serves as a retainer for the clutch which has previously been in engagement with
the rotating wheel for imparting a round-and-round movement of the cam cylinder.
As soon as this retaining lever is tripped, therefore, the clutch is moved into
engagement with the reciprocating wheel and to-and-fro movement is imparted to
the cam cylinder.
When it is again desired to change from to-and-fro to round-and-round knitting
the other arm of the lever which controls the supplementary drawing down cam is
acted upon by a pin or another arm, connected to the other pawl engaging with the
second ratchet on the hub of the spur pinion which operates the pressers, hence, the
supplementary drawing down cam is again pressed inward to operative position.
The same arm which effects this movement may be connected to the belt shifting
devices on the main driving shaft, and the pawl connected to said arm, may, at
appropriate intervals, be acted upon by a high link of the pattern chain, so as to
lift said arm sufficiently to permit of the shifting of the belt and the stoppage of the
machine.
The transverse shaft which is geared to the cam cylinder of the machine, has two
spur pinions, one of which meshes with a spur wheel on the driving shaft, and the
clutch engages with this pinion when the cam cylinder is to be rotated, but when
the cam cylinder is to be reciprocated, the clutch engages with the other pinion,
which meshes with a toothed segment forming part of a bell crank lever, which is
connected by a suitable pitman to a crank pin on the before mentioned spur wheel
on the driving shaft.
It is important that the cam cylinder should begin its to-and-fro movement
always in one and the same direction, hence the reciprocating pinion, which is
operated by the toothed segment, has two yielding pins, both acted on by springs
tending to project them, one pin having a projecting finger acting on a curved arm,
carried by the other pin, so that when the first pin is depressed by the pressure of
the clutch finger on its bevelled head, the other pin will be likewise depressed, and
hence the clutch finger will not engage with either pin while the wheel is moving
in this direction, but when the wheel is moving in the opposite direction the clutch
finger will depress only the pin in advance, and will be engaged by the succeeding
pin, so that the reciprocating movement of the clutch will always be started when
the pinion engaging the same is moving in one and the same direction.

Improvements in Automatic Knitting Machines.
We ROBERT WALTER SCOTT and LOUIS NAPOLEON DEVON WILLIAMS both
of 2079 East Cumberland Street in the City of Philadelphia State of Pennsylvania
United States of Ameria Manufacturers of Knitting Machinery 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:-
Our present invention comprises certain improvements in the knitting machine

page_text: for which we obtained Letters Patent No. 1240 dated January 23rd 1890 our
present improvements comprising certain modifications or elaborations of the
detailed construction of the machine with the general view of rendering the same
more effective in its action.
Our improvements may be summarized generally under the following heads :-
1st. Certain improvements in the cams which act upon the bits of the needles
during the knitting operation with the view of rendering such cams automatic in
action and preventing injury to cams and needles, and also to provide for readily
adjusting such elements of the cam mechanism as become worn in use.
2ndly. Improvements in the mechanism for operating the presser plates which
move the needles into action.
3rdly. Certain supplementary pressers for throwing all of the fashioning needles
into action for one or more courses when the narrowing operation has been completed
and before the widening operation begins.
4thly. Certain trippers for effecting the automatic movement of the cam which
throws the needles into operative position in making plain tubular work and for
permitting the shifting of the clutch in changing from to and fro knitting, to round
and round knitting, and in stopping the machine when desired, and
5thly. A special form of clutch whereby the.machine is always caused to start in
the proper direction in commencing the to and fro movement.
We will describe these various movements in the order enumerated, referring to
the accompanying drawings, in which-
Figure 1, is a plan or top view of the machine, the needle cylinder, the vibrating
presser plate carrier, and the parts mounted thereon being removed, to show parts
beneath;
Figure 2, is an end view looking in the direction of the arrow a Figure 1,
with part of one of the spur driving gears broken away to show parts behind it;
Figure 3, is an end view looking in the direction of the arrow y, Figure 1;
Figure 4, is an enlarged view of the cams of the cam cylinder, representing the
same as in a flat, instead of in a circular plane ;
Figure 5, is a view, partly in top elevation, and partly in section on the line w w,
Figure 4;
Figure 6, is a plan or top view on a larger scale than Figures 1, 2 and 3, of part
of the mechanism for operating the presser plates;
Figure 7, is a side elevation of the same;
Figure 7 is a plan view of a worm shaft and worms, forming part of said
mechanism.
Figure 8, is a plan or top view of another form of said mechanism ;
Figure 9, is a side clevation of the same; and
Figures 10 to 14, are views of a special form of clutch forming part of the
machine.
The present machine has two side cams 1, 1, (Figure 4) each of which serves to
lift the needles when traversing in one direction, and to depress the needles when
traversing in the opposite direction, and between these two side cams and above the
same is pivoted a swinging cam 2, which can move into contact with either side cam
as shown by dotted lines, so that the bits of the needles rising over one cam are
properly directed to the drawing down face of the other cam, and are prevented
from coming in contact with the corner of said cam so as to break or otherwise
injure the needles or other parts of the machine.
The end cams 3 which lift the needles to the inoperative position, are not
pivoted, as in the former machine, but are fixed, and between these end cams and
the side cams 1 before referred to are sliding cams 4 which can be moved in one
direction or the other by contact with the bits of the needles. When either of
these sliding cams 4 is moved towards its corresponding lifter cam 3, it is stopped
by contact therewith as shown at the left in Figure 4 and serves to direct the
needles from the side cam 1 up to the lifter cam, but when said sliding cam 4 is
moved away from the lifter cam 3, as shewn at the right in Figure 4, it permits the

page_text: bits of the needles to pass under said lifter cam so that they will be acted upon by
the advancing side cam.
The cam 5, which in producing plain tubular work acts upon the bits of the
needles so as to restore the latter to operative position after they have been raised
to inoperative position by the final lift cam, is mounted upon a spring 6 (Figure 1)
which tends to retract the cain and render it inoperative, but said cam is acted
upon by a lever 7 which in turn is under the influence of certain operating devices
hereinafter to be referred to, so that the said supplementary drawing down cam is
thrown into and out of action at the proper times, that is to say, it is thrown into
action in changing from to-and-fro to round-and-round knitting, and out of action
in changing from round-and-round to to-and-fro knitting.
The lifter cams 3 are carried by stems 8 mounted in brackets 9 on the cam
cylinder 10, as shown in Figure 5, and these cams are considerably deeper than
the amount of projection of the same into the cam cylinder for acting on the needles,
so that when the inner or acting end of the cam becomes worn, the worn portion
can be ground off and the cam projected further into the cylinder so as to bring a
new surface into play.
The presser plates 11 are mounted in a vibrating frame 12 (Figure 6) as in the
former machine, and have toothed segments 13 meshing with spur wheels 14 carried
by short vertical shafts 15 on said frame, but these shafts are operated in a manner
different from that heretofore adopted, that is to say, each shaft has a worm
wheel 16 which meshes with a worm 17 carried by a transverse shaft 18 mounted
in bearings on the vibrated frame, and this transverse shaft has at one end a spur
pinion 19 meshing with a large spur wheel 20 loosely mounted on the axial shaft 21,
of the vibrated frame. If this spur wheel 20 is held stationary while the vibrated
frame is rising, and is permitted to turn loosely when said frame is descending, the
meshing therewith of the spur pinion 19 on the transverse shaft 18 during the
rising movement will cause said spur pinion to turn in one direction, while if
the spur wheel 20 is held stationary during the downward movement of the vibrated
frame 12 and is permitted to turn loosely on the upward movement, the spur
pinion 19 will be caused to turn in the contrary direction, hence the transverse
shaft 18 and its worms 17 can be caused to turn in one direction or the other,
depending upon whether the spur wheel 20 is locked against movement in one
direction or in the other.
This locking of the spur wheel 20 is effected by providing the hub of the same
with two ratchet wheels 22 and 23, one right handed and the other left handed, and
each of these ratchet wheels is provided with a retaining pawl 24, that for one
wheel serving to prevent forward movement, and that for the other wheel serving to
prevent backward movement.-
These pawls 24 are under control of pattern chains 25 so that when one is in
action, the other is held out of action, hence, the spur wheel 20 can be locked
against forward movement with the vibrating frame, or against backward movement
with the same, as required, or both pawls can be held out of action, when it is not
desired to move the shaft 18.
The worms 17 on the transverse shaft 18 are so constructed as to act alternately
so that movement is imparted alternately to the presser plates 11 of the vibrating
frame 12.
In order to accomplish this result the teeth of each worm are at right angles to
the axial line of the worm throughout the greater portion of the circumference of
the worn but throughout the remaining portion of the said circumference are
inclined the inclination being to the extent of one tooth as shewn in Fig. 7 and the
inclined portions of the teeth of one worm are diametrically opposite to the inclined
portions of the teeth of the other worm as shewn in Fig. 7 in which said inclined
portions of the teeth of the right hand worm are shewn by full lines at the top of
the worm while the inclined portions of the teeth of the left hand worm are slewn
by dotted lines at the bottom of said worm, hence when one worm wheel is being

page_text: acted upon and moved by engagement with the inclined portions of the teeth of one
worm, the other wheel is stationary and is locked by engagement with the straight
teeth of the other worm.
On the vibrating frame 12 are mounted supplementary segmental presser plates 26
which are sufficient in extent to cover all the fashioning needles on each side of
the machine, that is to say, they cover the needles extending from the innermost
point in the narrowing to the outer ends of the fashioning set, so that, after the
main presser plates 11 have been contracted to their full extent and the full narrowing
of the web has been effected, these supplementary plates 26 may be brought into
operation for one or more courses, so as to form a band of full width in the centre
of the bulge or pocket which is being knitted.
These plates 26 may be loosely pivoted to the vibrating frame, as shown in
Figures and 7, so that under ordinary circumstances they are free to rise and fall,
and hence have no depressing effect upon the needles beneath them, but when the
main presser plates 11 have been fully retracted, pins or projections 27 on said
presser plates or on their segmental racks 13 engage with like pins or projections 28
on the supplementary presser plates 26 and thus lock the latter in the depressed
position and cause them to act upon the needles so long as they are thus locked, the
movements of the main presser plates 11 in commencing the widening operation
causing the disengagement of the pins or projections 27 and 28 and thus again
freeing the supplementary presser plates 26.
Instead of this plan, however, the supplementary presser plates 26 may be carried
by a special frame or by a pair of levers 29 acted upon by cam discs 30, the latter
being secured to a shaft 31, which has a spur gear 32 meshing with a like gear 33
loose on the shaft 21, but having a ratchet wheel 34 which, on the backward
movement of the plate 12, can be retained by a pawl similar to one of the pawls 24,
and, like it, under control of a pattern chain 25 so as to effect the operation of said
supplementary presser plates 20 at the proper times, (see Figures 8 and 9).
A spring catch 35 engages with a notched disc 36 to prevent overrunning
of the shaft 31, and a spring catch 37 and notched disc 38 prevent excessive
movement of the worm shaft 18.
The shaft 21 which carries the plate 12 is vibrated by a crank pin on a spur
wheel 40 (Figure 2) on the shaft 41 which drives the cam cylinder 10 of the
machine, this crank pin acting through the medium of a rod 42 upon a weighted
arm 43 on said shaft 21 and the latter has near the opposite end another arm 44
(Figure 3) which operates a pawl 45 acting on a ratchet wheel 46 on the sprocket
drum 47 which operates the pattern chains 25.
The lever 7 which acts upon the supplementary drawing down cam 5 so as to
press the same inward for action during round-and-round knitting, has two arms 50
and 51 and when changing from round and round knitting to to and fro knitting,
one of the arms of this lever is acted upon by a pin 52 carried by a pivoted arm 53
which is connected to the pawl 24 acting on one of the ratchets on the hub of the
spur wheel 20 which operates the gearing for moving the presser plates.
When this pawl is raised out of action therefore the pin 52 on the arm 53
connected with the pawl acts upon the arm 50 of the lever 7 which controls the
drawing down cam and moves the said lever to the position shown by dotted
lines in Figure 1, so as to permit the cam to be withdrawn from action by its
spring 6.
The arm 53 is also connected by preference to the trip lever of the belt shifter,
and when the arm has been raised so as to operate the lever 7 in the manner set
forth, a high link on the chain 25 acts on the pawl 24 and lifts the arm 53 still
higher so as to release said trip lever, and permit the belt to shift so as to stop the
machine.
The driving shaft 41 for the cam cylinder 10 has in addition to the rotating spur
pinion 40, before referred to, a reciprocating spur pinion 55, both of these pinions
being operated by means of devices hereinafter described and both being loose on said

page_text: driving shaft, but between the two pinions is a clutch sleeve with oppositely
projecting pins, one for engaging with a pin on the pinion 40 and the other for
engaging with pins on the pinion 55.
This clutch sleeve is controlled by a shifter 56 on a rock shaft 57 which has an
operating handle 58, and a toe 59 for engagement with a projection on one arm of a
lever 60, hung to the bed of the machine.
When the machine is stopped after the operation of the lever 7 as above
described, the rock shaft is operated by the handle 58 so as to throw the clutch
sleeve into engagement with the reciprocating pinion 55 so that to and fro motions
are imparted to the cam cylinder, the same movement causing the toe 59 to engage
with the lever 60 so as to hold the clutch in this position.
Just before the last reciprocation of the cam cylinder a pin 61 on an arm 62
connected to the other pawl 24 is raised into the path of the arm 51 of the lever 7
and the latter is again turned to the position shown by full lines in Figure 1 so as
to again throw the drawing down cam 5 into operative position..
At the same time a cam 63 on the lever 7 is brought into position to act upon
the lever 60, and the latter is moved so as to release the toe 59 and permit the
clutch to be moved into engagement with the rotating pinion 40 by reason of the
action of a spring 64 on an arm 65 projecting from the belt shifter, so that round
and round knitting is again proceeded with.
The spur pinion 40 meshes with a spur wheel 66 on the main driving shaft of
the machine, but the other pinion 55 meshes with a toothed segment 67 forming
part of a bell crank lever 68 which is connected by a suitable pitman 69 to a
crank pin 70 on the before mentioned spur wheel 66 on the driving shaft, so that a
reciprocating or back and forth motion is imparted to the pinion 55.
It is important that the cam cylinder should begin its to and fro movement
always in one and the same direction, hence the reciprocating pinion 55 which is
operated by the toothed segment 67 has two yielding pins 71 and 72 (Figures 10
to 14) both acted on by springs 73 tending to project them, the pin 71 having a
projecting finger 74 acted on by a curved arm 75 carried by the other pin 72° so
that when the latter pin is depressed by the pressure of the clutch finger 76 on its
bevelled head, as shewn in Figure 12, the other pin will be likewise depressed, and
hence the clutch finger will not engage with either pin while the wheel is moving
in this direction, a pivotted toe 77 on the pin 72 serving to carry the clutch finger
beyond the pin 71 before the latter rises, but when the wheel 55 is moving in the
opposite direction the clutch finger 76 will depress only the pin 71 in its advance,
as shown in Figure 13, and will be engaged by the pins, as shown in Figure 14, so
that the reciprocating movement of the clutch will always be started when the
pinion engaging the same is moving in one and the same direction.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is: -
First. The combination of the side cams with the swinging top cam for directing
the bits of the needles to the drawing down portion of either side cam and
preventing contact of said bits with the points of the cams substantially as herein-
before described.

into operative position after they have been moved out of operative position by
the other cams of the machine, with mechanism for automatically tripping said
drawing down cam in changing from round and round to to-and-fro work, or vice
versa substantially as hereinbefore described.
Ninth. The combination of the cam cylinder and its drawing down cam moved
in one direction by a spring and in the other direction by a lever with toes for
