Improvements in Circular Knitting Machines:
JOHN CHARLES MOORE, Hosiery Machinist, 18, Crafton Street, Leicester, in
the County of Leicester, do hereby declare the nature of this invention to be as
follows:-
The improvements in this invention are applicable to circular knitting
machines, and especially to circular reverseable knitting machines that produce
stockings and the like with shaped heels and toes automatically.
The various combinations and improvements which I propose to make are
more particular for le purpose of improving the manufacture of rib fabric
and making such articles as rib stockings and the like, but some of these
improvements are also applicable to machines which produce similar articles
in plain fabric, and in some cases do not make the heels and toes, but make
fabric only, and the heels and toes and the like are made by other means.
A number of these improvements consist of certain modifications of the
mechanism as specified in my Patent No. 20640 1895 "which was applicable
only for plain stockings and the like" and the conjunction of these and other
new features and combinations, enable me to produce rib fabric and make such
articles as rib stockings and the like automatically.
These improvements are as follows.
A new arrangement of knitting cams, this consists of several sections being
fitted in the cam cylinder of machine so as to form a ring, or the same result
may be obtained by fitting a solid ring in the cam cylinder, it is now shaped
on the edge so as to form projections that will raise the needles and allow the
knocking over cam to depress the same, it is also bevelled in such a manner so
that upon the operative projection of the jacks, or needles, leaving the knocking
over cam, they immediately come into contact with the bevelled portion of the
cam which depresses the aforesaid operative projection of jacks, or needles,
below the surface of the needle cylinder and by these means the needles are only
allowed to rise to such a height as will retain the loops of fabric upon the
needle latches, but just prior to coming into contact with the foregoing knocking
over, or stitch cam again, they are raised by means of the projection on the
cam ring so as to cast the loops off the latches on to the stem of needles, this
operation being identical whichever way the machine revolves.
An improvement in the form of the knocking over, or stitch cam, I propose
to-shape this cam so as to allow a period of rest, to the needles, or nearly so,
about midway down the cam, this allows me to bring the latches of needles into
such a position as they will lay over the loops of fabric but not sufficient to
close the same and by this arrangement I am enabled to wrap the yarn round
the latches of needles when making heels and toes, in the same manner, as is
done by hand opeiatives. I also propose to controll the aforesaid knocking over
<

page_text: cam in an improved manner that will ensure it receeding into position for
knitting which ever way the machine revolves with absolute certainty. I
accomplish this by means of an oscillating lever, or its equivalent, which is
attached to the slide that the cam is fixed upon, this lever being brought into
such a position by means of the cam.stops, or their equivalent, which enable it
to be operated upon by the jack tails, or projections, when they come into
contact with the same which ever way the machine revolves.
I further propose to fit a sliding cam in the needle cam cylinder which will
allow the operator to controll those frame needles which are required to have
the loops taken off and placed on to the rib machine needles, and vice-versa.
An improved combination of jack, spring, and needle, this consists of a jack
having a slot in it,. or its equivalent, for receiving a spring which may either
be, soldered or attached to the jack when placing it in the machine and allowed
to remain loose in the aforesaid slot, a slot, or its equivalent, is also in the jack
for the purpose of receiving the projection of needle, this enables me to controll
the needles by means of the jacks, substantially the same as in my former
Patent 20640/95 where I employed a spring needle and jack.
An improved design of spring needle and jack, this is a modification of the
spring needle and jack as described in my former Patent 20640/95, and consists
of a plain stem needle having a loop or bow turned at the end and finishing
with a projection standing at about a right angle to the stem of needle. A slot
is formed in the jack to fit upon the aforesaid projection, being substantially
the same as one of the designs in my former Patent 20640/95, except in the
present case by reason of the foot, or projection, soldering is not required.
An improved sinker, and spring, and their combination being a modification
of the sinker and spring previously employed in my Patent 20640/95.
In this design of sinker I have reversed the method formerly used, at the
fulcrum, and in place of a slot, I form a semi-circular projection which oscillates
in a support having a recess suitably shaned to receive the same, and in place of
the straight spring I used formerly I now employ a spring with a half coil,
or coil, situated between the point of attachment and the opposite end, these
springs may be soldered to the sinkers as before, but I propose to effect an
improvement in this respect, and in place of soldering the spring to the sinker
I employ a clip, or its equivalent, which slides over that part of the sinker where
the slot is situated, and by placing the spring in the slot, and fixing the clip
on the sinker over the same, I can by these means attach the springs to the
sinkers in a reliable manner, and dispense with the soldering.
"
An arrangement whereby I am enabled to hold the rib machine, or dial
firmly in position and shogg the same when necessary "dispensing with such
means as wheel combinations, or dial posts, and lugs as is usually employed
this consists of a hollow spindle, or its equivalent, which revolves in a socket
that is mounted on the machine, a prong, or driving peice is attached to this
spindle the end of which oscillates in a groove, or its equivalent that is located
along the arm of the rib machine, and as the rib machine arm revolves with
the machine it causes the above socket to revolve at the same rate of speed,
the yarn passing through a slot in the spindle, or its equivalent, to the guide
of machine to the needles.
The application of a spring to the yarn trapper in order to make the take up
of the slack yarn more certain, and more sensitive than the present methods
employed.
A method for controlling the frame needles and retaining them in the machine
and out of operation when the loops have been transfered to the rib machine
needles. I obtain this result by means of detachable bits which are placed
upon the narrowing, or depressing levers that are described in my Patent 20040/95,
these detachable bits being operated upon by means of a cam, or cams, or their
equivalent, which are fitted upon the revolving cylinder of machine, other
methods may be employed, such as tuck presser wheels, or a combination of

page_text: cut, or recessed jacks and the like, and such means as these I consider would
be equally applicable for the purposes of this invention, although not quite so
desireable.
:
An improved narrowing or depressing lever, in my Patent 20640/95 these
levers were made straight and depended upon the spring needle and jack to
place them out of action, my improved design is somewhat similar except that
at the lower end, near the fulcruin I have a projection standing at a convenient
angle and by means of a cam, or its equivalent being attached to the cylinder
of the machine and passing over this projection it places the levers out of
operation independently of any other means.
An improved take up for the fabric, this consists of two rollers fitted into a
frame and suitably geared, and is controlled by a clutch motion, or its equivalent,
working in conjunction with a lever fitted upon a convenient part of the machine,
the main feature of novelty in this part of my invention consists of being able
to release the pressure, or weight automatically while heels and toes are being
made on the machine, and to immediately come into action automatically upon
the completion of same, by this arrangement the risk of making imperfect heels
and toes when working common yarns is reduced to a minimum.
An improved apparatus for splicing stockings, and the like in any part of
the same where they are subject to the greatest wear, being generally employed
to thicken the knees, ankles, and soles of feet, and is commonly known as half
round splicing.
< viz." the
The object of this part of my invention is to overcome those difficulties which
have always been so apparent in this class of splicing arrangement,
uncertainty, and the liability of missing when in operation.
I propose to obtain this result by a combination of novel features and parts
as follows.
I first fit up upon the machine a yarn guide suitably constructed to receive
a yarn trapper, or cutter, or a combination of trapper and cutter, which is for
the purpose of severing the splicing thread, I now arrange upon the yarn guide,
or other suitable place an additional yarn guide which has a swinging, sliding,
or oscillating motion and the yarn which is being fed to the machine passing
through the same prior to entering the main yarn guide, thus allows me to
controll the relative position of the yarn and splicing thread and the moveable
guide being controlled by means of a cam, or its equivalent, it enables me to
bring the main yarn into contact with the splicing yarn when the trapper is.
opened and in such a position as to overlap the splicing thread some distance
beyond the point of severance "which as been caused by the aforesaid trapper,
or cutter," and by frictional contact with the same causes it to immediately
pass along with the main yarn into the other yarn guide to the needles of the
inachine and upon the completion of the part which it is necessary to splice
the cam that operates upon the moveable yarn guide releases the same and allows
it to take the yarn clear of the trapper, or cutter while the aforesaid trapper,
or cutter comes into operation to sever the splicing thread, a slackening arm is
also arranged to work in conjunction with the aforesaid parts the whole of the
movements being put into and out of operation by suitable cam motion, or its
equivalent arrangement fitted upon the base of machine.

COMPLETE SPECIFICATION.
!
JOHN CHARLES MOORE, Hosiery Machinist, 18, Crafton Street, Leicester, in
the County of Leicester, do hereby declare the nature of this invention and in

page_text: what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The improvements in this invention are applicable to circular knitting
machines, and especially to circular reverseable knitting machines that produce
stocking and the like with shaped heels and toes automatically.
The various combinations and improvements which I propose to make are
more particular for the purpose of improving the manufacture of rib fabric,
and making such articles as rib stockings and the like, but some of these
improvements are also applicable to machines which produce similar articles
in plain fabric, and in some cases do not make the heels and toes, but make
fabric only, and the heels and toes, and the like, if required are made by other
means.
A number of these improvements consist of certain modifications of the
mechanism as specified in my Patent 20640/95 "which were applicable only for
plain stockings and the like" and the conjunction of these and other new
features, and combinations, enable me to produce rib fabric and make such
articles as rib stockings and the like automatically.
These improvements are as follows. A new arrangement of knitting cams
this consists of several sections being fitted into the cam cylinder p, Fig. 17
so as to form a ring, or the same result may be obtained by fitting a solid ring in
the cam cylinder, it is now shaped on the edge at the points d, d, Fig. 17 thus
forming projections that will raise the needles and allow the knocking over
cam, a, to lower the same, it is also bevelled at c, c, and upon the operative
projection o, of jack Fig. 17, or butts of needles leaving the knocking over
cam a, they come into contact with this bevelled portion which depresses the
aforesaid operative projection of jack below the surface of the needle cylinder n,
Fig. 17, and by these means the needles are only allowed to rise to such a height
as will retain the loops of fabric upon the needle" latches, but just prior to coming
into contact with the foregoing knocking over cam again they are raised by
means of the projections d, d, on the cam ring so as to cast, the loops off the
latches, on to the stem of needles this operation being identical whichever way
the machine revolves.
An improvement in the form of the knocking over, or stitch cam, I propose
to shape this cam so as to allow a period of rest to the needles, or nearly so about
midway down the cam, a, at the points, b, b, Fig. 17 this brings the latches of
needles into such a position as they will lay over the loops of fabric, but not low
enough to close the latches of needles and admits of the yarn being wrapped
round the latches when making heels and toes, and the like, and by these means
I produce a similar effect as when made by hand operatives, I also propose to
control the aforesaid knocking over cam in an improved manner that will
ensure it receeding into position for knitting which ever way the machine
revolves, with absolute certainty.
I accomplish this by means of an oscillating lever a Fig. 15, or its equivalent,
which is attached to the slide a¹ Fig. 16, that the cam a, is fixed upon the ends
of this lever c, and d, being brought into the position as at, c, by means of the
cam stops and 2 Fig. 15, or their equivalent, which enable it to be operated
upon by the jack tails o, Fig. 17, when they come into contact with the same
this causes the cam a. to receed until it is reversed by the opposite stop 61 and
the same operation takes place which ever way the machine may revolve.
I further propose to fit a sliding cam f, Fig. 17 in the needle cam cylinder
which will allow the operator to control those frame needles which are required
to have the loops taken off and placed on to the rib machine needles, and
vice-versa.
Figs. 4-5, an improved combination of jack, spring, and needle, this consists
of a jack having a slot in it, or a recess, or their equivalent for receiving a spring
which may either be soldered, or attached to the jack when placing it in the

page_text: machine and allowed to remain loose in the aforesaid slot, or recess, a slot or
its equivalent is also in the jack for the purpose of receiving the projection of
needle, this enables me to controll the needles by means of the jacks substantially
the same as in my former Patent 20640/95, where I employed a spring needle
and jack.
Fig. 3, an improved design of spring needle and jack, this is a modification
of the spring needle and jack as described in my former Patent 20640/95, and
consists of a plain stem needle having a loop, or bow turned at the end and
finishing with a projection standing at about a right angle to the stem of needle,
a slot is formed in the jack to fit upon the aforesaid projection, being sub-
stantially, the same as one of the designs in my former Patent 20640/95 execept
in the présent case by reason of the foot, or projection, soldering is not required.
Figs. 7, 8, 9, 10, 11 an improved sinker, and spring and their combination,
being a modification of the sinker and spring previously employed in my Paient
20640/95. In the present design of sinker I have reversed the method formerly
used, at the fulcrum, and in place of a slot, I form a semi-circular projection, e,
which oscillates in a support having a recess suitably shaped to receive the same,
and in place of the straight spring I used formerly I now employ a spring which
may either have a loop formed at one end, or a half coil, or coil which would
be situated between the point of attachment and the opposite end, the springs
may be soldered to the sinkers as before; but I propose to effect an improvement.
in this respect, and in place of soldering the spring to the sinker, I employ a
clip or its equivalent which slides over that part of the sinker where the slot is
situated, and by placing the spring in the slot, and fixing the clip on the sinker
over the same I can by these means attach the springs to the sinkers in a
reliable manner, and dispense with soldering the same.
Figs. 1-2, an arrangement whereby I am enabled to hold the rib machine,
or dial firmly in position and shogg the same when necessary, "dispensing with
such means as wheel combinations, or dial posts and lugs which are usually
employed this consists of a hollow spindle, g, or its equivalent which revolves
in a socket which is mounted on the machine, a prong, ml, or driving peice is
attached to this spindle, the end of which oscillates in a groove a¹ or its equiva-
lent that is located along the arm of the rib machine, and as the rib machine
arm revolves with the machine it causes the above socket to revolve at the same
rate of speed, the yarn passing through a slot in the spindle, or its equivalent
to the guide of machine and on to the needles.
The application of a spring to the yarn trapper in order to make the take up
of the slack yarn more certain and more sensitive than the present methods
employed.
•
A method for controlling the frame needles and retaining them in the machine
and out of operation when the loops have been transfered to the rib machine
needles.
I obtain this result by means of detachable bits Fig. 13 which are placed
upon the narrowing, or depressing levers Fig. 12 that are described in my
former Patent 20640/95, these detachable bits being operated upon by means
of a cam, or cams, or their equivalent, which are fitted upon. the revolving
cylinder of machine, other methods may be employed, such as tuck presser
wheels, or a combination of cut, or recessed jacks and the like, and such means
as these I consider would be equally applicable for the purposes of this invention,
although not quite so desireable.
Fig. 12 an improved narrowing or depressing lever, in my Patent 20640/95
these levers were made straight and depended upon the spring needle and jack
to place them out of action, my improved design is somewhat similar except
that at the lower end, near the fulcrum I have a projection, a, standing at a
convenient angle, and by means of a cam, or its equivalent being attached to
the cylinder of machine and passing over this projection it places the levers out
of operation independently of any other means.

page_text: Figs. 18-19-20-21-22-23 an improved apparatus for splicing stockings
and the like in any part where they are subject to the greatest wear, being
generally employed to thicken the knees, ankles, and soles of feet and is commonly
known as half round splicing. The object of this part of my invention is to
overcome those difficulties which have always been so apparent in this class of
splicing arrangement "viz." the uncertainty and liability of missing when in
operation. I propose to obtain this result by a combination of novel features
and parts as follows, I first fit up upon the machine a yarn guide a suitably
constructed to receive a yarn trapper, or cutter, or a combination of trapper
and cutter, which is for the purpose of severing the splicing thread, I now
arrange upon the yarn guide, or other suitable place an additional yarn guide, a,
which has a swinging, sliding, or oscillating motion and the yarn which is being
fed to the machine passing through the same prior to entering the main guide,
this allows me to controll the relative position of the yarn and splicing thread,
and the moveable guide being controlled by means of a cam, or its equivalent,
it enables me to bring the main yarn into contact with the splicing yarn when
the trapper is opened and in such a position as to overlap the splicing thread
some distance beyond the point of severance "which as been caused by the
aforesaid trapper, or cutter" and by frictional contact with the same causes it to
immediately pass along with the main yarn into the other yarn guide to the
needles of the machine, and upon the completion of that part which it is
necessary to splice, the cam which operates upon the moveable yarn guide
releases the same and allows it to take the yarn clear of the trapper, or cutter,
while the aforesaid trapper, or cutter comes into operation to sever the splicing
thread, a slackening arm is also arranged to work in conjunction with the
aforesaid parts, the whole of the movements being put into, and out of operation
by suitable cam motion, or its equivalent arrangement fitted upon the base of
the machine.
In order that the foregoing description may be more readily understood I
will now proceed to describe the following drawings.
Fig. is the rib machine arm and swivelling socket arrangement which
holds the dial in the correct position and central over the needle cylinder, a,
is the upper portion of the rib mahine arm, b, is the dial which is fixed to
the spindle, c, this spindle extending upwards through the boss of the rib
machine arm, and upon the upper part is fixed the link, or lever, e, an axle is
fitted on the end of this link at the point. f, the upper part of same fitting in
the lower end of swivelling socket. g. this socket, g, is fitted into the fixed
bearing, d, which is located above the rib machine arm and some distance from
the centre of machine, and by these means I can hold the rib machine dial rigid.
The yarn now passes through the upper part of the spindle, g. "which is hollow"
and comes out through the slot. h. passing on to the guide, or feeder of the
machine. Now in order that this yarn may not get ravelled with the revolving
arm, a, and the fixed bearing. or bracket. d, it is necessary to revolve the socket
spindle. g. at the same rate of speed as the rib machine arm, a, revolves so that
the relative position of the slot. h. in the spindle, a. shall be permanent with
the varn guide, or feeder of machine, and I accomplish this by means of the.
driving peice or prong. m, one end being fixed to the spindle. g. at the point, m¹,
the other end at. m², fitting into the groove which is located on the upper side
of the rib machine arm. a. at the point. a. the result of this combination is
that upon the rib machine arm, w, revolving with the machine the prong, or
driving peice, m. oscillates in the groove, a', of rib machine arm and this causes
the socket spindle, g, to revolve simultaneously with the machine, and by these
means the relative position of the slot, h. in the spindle, g, is permanently
maintained with the yarn guide of the machine and allows a free passage for
the 770.35

Fig. 4 is an improved jack, spring, and needle the spring may either be
soldered in the slot, a, or allowed to remain loose in the same.
Fig. 5 is an improved jack, and spring being a modification of Fig. 4 but in
this case soldering not required as the operator can readily place the spring
between the needle and jack when they are in the grooves of machine, the spring
remaining loose.
Fig. 6) is a spring needle and jack being a modification of Fig. 3.
Fig. 7) is the improved sinker.
Fig. 8, is the improved sinker shewing the method of attaching the coil
spring to same by means of the steel clip, d.
Fig. 9, is the clip, d, which holds the spring, b, in position.
Fig. 10, is the coil spring.
Fig. 11, is a section of the support, or bearing which the bottom part of the
sinker Fig. 7 oscillates in, e, is the semi-circular projection of sinker fitting
into a corresponding recess in the bearing, or support at the point, h, and is held
in operative position by the projection, c, on the cylinder, or its equivalent,
which is fitted to allow the curved projection of sinker to swing freely and
without shake, but admits of taking any of the sinkers out of the machine when
pressed forward so that the projection, c, and, g, may miss each other.
Fig. 12, is the improved depressing lever having the projection, a, which
when operated upon by means of a cam that is fixed to, the cylinder of machine
it brings these depressing levers out of action, independently of the spring needle
and jack, or jack, spring and needle.
Fig. 13, is the steel clip which is placed on all those depressing levers at about
the point, c, that are required to controll the needles and keep them out of
knitting operation when the loops of same have been transfered to the rib
machine needles, these clips being operated upon by a cam that is attached to
the revolving cylinder of machine.

of the cams inside same, a, is the improved sliding knocking over cam shaped
at the points b, b, to allow the needles to have a period of rest, or nearly so,
while knitting for the purpose specified, e, e, is the knitting steel cam ring having
projections at the points d, d, for raising the needles so as to cast the loops off
the latches on to the stem of needles "commonly known as clearance"
the portions of the cam which are bevelled in order to depress the operative
projection o, Fig. 17, of jacks, or needles below the surface of needle cylinder
for the purpose specified.
c, c, are
Fig. 15, is a plan of Fig. 14 shewing the oscillating retarding lever, which is
fitted upon the slide that the knocking over cam is fixed upon, also a section
of the adjustable cam stops, a, is the oscillating lever and b, 2, the sections of
the adjustable cam stops, this lever is depressed into position for being operated
upon by the operative projection of jacks, o, Fig. 17" or needles, at the point, c,
by means of the adjustable cam stop 2, and upon the machine changing from
circular to reciprocating motion the knocking over cam is made to slide back-
wards by reason of the point c, coming into contact with the operative projection
of jacks, or needles until it comes into contact with the opposite stop 6', which
immediately reverses the motion bringing the point d, into action, and by these
means I cause the knocking over cam to slide back, or retard into the correct
position for, knitting which ever way the machine may revolve.
Fig. 16, is another elevation of the knitting cam cylinder in section, this gives
a sectional view of the knocking over cam attached to the slide, and a section
of oscillating lever fitted upon same, also the vertical sliding cam which controlls
the frame needles while transfering the loops from frame needles to rib needles
and vice-versa, a, is a section of knocking over cam, and, the slide which the
same is attached to a², is a section of the oscillating lever f, is the vertical
sliding cam, bevelled at the points g.

I will now describe the various figs. of the improved splicing device by the
following letters of reference.
al, is the bracket which the splicing device is fitted into and is arranged to
swing out of position and away from the needles by removing the wing screw k,
el, and c², are guides which conduct the splicing thread from the spool to the
yarn trapper, or trapper and cutter, b, is the slackening arm to give slack to
the splicing thread, a, is the swinging guide, which controlls the main yarn h,
is a swing lug, or pin attached to the swinging guide, and is operated upon by
the slackening arni which is shaped at the point h³, so as to form a cam this
enables me to depress the swing yarn guide when the slackening arm is raised
and when it falls the spring g', immediately raises the guide to the upper
position this brings the yarn out of contact with the trapper, this trapper, or
cutter is pressed into position for severing the thread by means of the coil
spring f, and is released, or opened by the lever e, being raised, this lever being
bevelled on the inside upper edge and coming into contact with a pin which is
fixed to the trapper, or cutter and extends some distance through the bottom
part of the main yarn guide at 4, the effect of raising the lever e, is to force the
trapper out horizontally an allow a space for the splicing end to lay free, a sliding
rod or lever is now fitted to the cylinder of the machine which is operated upon
by means of a cam arrangement conveniently fitted to the base of the machine.
The upper part of this sliding rod, or lever is arranged to operate upon the
slackening arm cam g, at the point also upon the bevelled lever e, which opens
and closes the trapper c, at the point a and the effect of this sliding rod, or lever,
is, first, to release the slackening arm, second, to open the trapper, or trapper
and cutter, and, third, to immediately lower the swinging yarn guide which
bring the main yarn in close contact with the splicing thread and overlaps the
same a good distance which ensures the splicing yarn being taken into the hole
of main yarn guide and on to the needles of the machine, now when the lever,

page_text: or sliding rod is lowered by the aforesaid cam arrangement which is fitted to
the base of the machine, I obtain the contrary effect "viz." first, the raising of
the swing guide which brings the main yarn out of the reach of the trapper,
or trapper and cutter, then the falling of the slackening arm, this being followed
immediately by the closing of the trapper, or trapper and cutter which severs the
splicing thread and holds the same in position until the entire process is again
repeated.
Having now particular described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1st. The combination of the knitting cams in circular machines of all kinds
whether latch, or bearded needles are employed, substantially as illustrated
and described.
2nd. The combination of any of the various parts, or features of the knitting
cams for a like purpose in circular knitting machines.
3rd. The sliding cam which controlls the frame needles while transfering
takes place.
4th. The switching lever which is attached to the knocking over stitch cam
for the purpose of retarding the same so as to bring it into the correct position
for knitting substantially as specified.
5th. The knocking over, or stitch cam shaped so as to arrest the decent of
the needles about midway substantially as illustrated and described.
6th. The combination of the jack, spring, and needle, or any modification of
the same for a like purpose substantially as illustrated and specified.
7th. The spring needle and jack combination or any modification of the same
substantially as specified.
8th. The combination of the sinker, and the attachment of a coil spring to
same, by means of the adjustable clips substantially as illustrated and described.
