Improvements in and relating to Oircular Knitting Machinery, and
in Appliances therefor.
JOHN CHARLES MOORE of Crafton Street Leicester in the County of Leicester
Hosiery Machine Builder do hereby declare the nature of this invention to be as
follows:-
This invention as for its object an improvement in or relating to circular
knitting machinery of all kinds where self-acting needles are used but more
especially those employed in the manufacture of Cardigan jacket sleeves and
the like.
This improvement consists of automatic shogging mechanism in conjunction with
tucking, or continuous welting mechanism "the latter being commonly known as
roll cuff" and is employed for making sleeve cuffs and the like for Cardigan
jackets etc., it is arranged so that either styles, or designs, may be worked. as
required, the machine can also be built so as to only have the shogg mechanism on
if desired.
A further improvement consists of an arrangement whereby the stopping of the
machine takes place instantaneously when a breakage of the yarn occurs, or other
irregularities and when the bobbins run empty etc.
This improvement is so constructed that the ordinary style of circular rib
machine can be employed, that is to say circular rib machines having swing jacks,
or levers in the usual manner, with loose dial, or cup etc., and the cams being
located inside and outside and being worked by means of levers.
In order to carry out this invention for making shogg cuff in conjunction with a
tucking arrangement for making what is known as welt, or roll cuff on a circular
machine, or the machine can be made so as to only have the shogging mechanism
on if desired. I first arrange a vertical shaft passing through the bed of machine
in a convenient position this shaft may be connected by means of gear or chain
wheels, or it may be arranged to have an intermitten or semi, revolving motion;
a wheel is now mounted upon the top of rib machine which has the required
number of teeth in to make the roll cuff pattern and is geared to a small pinion
that is attached to the ordinary machine side spindle, and can be readily thrown in
or out of operation.
I next cut the same number of teeth in the wheel that is mounted upon the
aforesaid vertical shaft, and with another vertical shaft and two pinnion wheels
connect the top and bottom wheels; two sets of cams are now fitted upon the
wheel which is on the top of rib machine and are made adjustable so that either
Bets may be attached as required, these cams actuate the rib machine levers both
inside and outside. I then employ a clutch or other suitable arrangement to slide
upon the ordinary side spindle which connects the frame and rib machine together,
this gives the required movement to the rib machine which is necessary for it to
shogg, and allows the rib and frame needles to cross each other, this sliding
arrangement is then connected to a lever, this lever. being put in motion by cams
which are attached to the wheel that is fixed upon the vertical shaft on the bed of
machine.
I also construct the rib machine cup, or dial, in such a manner that it gives the
required rigidness and the necessary freedom for the jacks, or levers, to work
correctly; a further improvement is in the special shape of rib machine cam
plate, and cams, and their relation to the fraine cains, and what is known as the
welting cam, which is located outside the rib machine.

page_text: In cases where only the shogg arrangement is required various modifications may
be adopted, such as follows, or their equivilant, I may retain the gear wheel that is
fixed on the top of rib machine substantially as in the foregoing combination, but
dispensing with the wheels cams etc., that are necessary for making the continuous
welt, or roll cuff; or I may dispense with the wheel motion on the rib machine
altogether and connect the rib machine levers directly or otherwise so that they
may be operated upon by a special set of cams to be fixed upon the wheel that
operates the shogging lever.
It is obvious also that the initial motion required for the foregoing improvements
may be obtained by other means than a revolving, intermitten, or semi revolving as
specified, as a catch wheel and catch in conjunction with levers and cams, or
eccentric motion would give the same result. This shogging apparatus or
combination is applicable to all circular knitting machines having an ordinary rib
machine with lever jacks and the usual loose cup or dial..
The second part of this invention consists of mechanism whereby the machine
I can be stopped instantaneously when a breakage in the yarn or empty bobbins
occur etc.
a
In carrying out this improvement I errect a shaft at the back of machine having
a number of catch or tooth wheels fixed thereon. this shaft is operated upon by
loose pulley having a crown catch wheel, or clutch on the side and is held in
position by a suitable spring which puts it in contact with a similar clutch on the
shaft; this pulley may be then, connected by means of a belt or chain to the
machine driving shaft or pulley, or I may arrange so that the shaft has a semi-
revolving motion by means of levers and catches operating on a suitable part of the
machine.
1 next arrange a bar to run over the top of these catch wheels having as
many tubes mounted thereon as there are threads being worked by the machine,
peices of wire are now made to slide freely on these tubes, having hooks or eyes in
the top from which point they may be attached either directly or by means of
cords or their equivalent, to balance guides so that if any of the threads break or
give way these wires fall and coming in contact with the catch, or tooth wheels stop
them from revolving, this brings into operation the necessary levers etc., to
immediately stop the machine.
"
This stopping device is applicable to circular knitting machines of all kinds.

Improvements in and relating to Circular Knitting Machinery, and
in Appliances therefor.
JOHN CHARLES MOORE of 18, Crafton Street Leicester in the County of
Leicester Hosiery Machine Builder, 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 has for its object an improvement in, or relating to circular
knitting machinery of all kinds where self-acting needles are employed.
The first part of this invention consists of automatic shogging mechanism, and
is employed for making fancy designs for such articles as Cardigan jacket sleeve
ouffs and the like.
The special feature of this improvement consists of an arrangement whereby
the ordinary style of circular rib machine can be employed, that is to say, circular
rib machines having swing jacks, or levers, with loose dial, or cup, and the cams
being located inside and outside, and being worked by means of levers.

page_text: In order to carry out this invention for making shogged cuffs and the like,
I first arrange a vertical shaft, passing through the bed of machine in a con-
venient position, and with a suitable bearing for it to revolve in; on the lower end
of this shaft is fixed a spur wheel, which is operated upon by means of a quadrant
which revolves with the machine, being so arranged that the necessary number of
revolutions take place to form the pattern required by when the spur wheel has
completed one revolution, this quadrant is thrown in, or out of operation when
required by a small eccentric placed in a suitable position.
A wheel is now mounted upon the top of rib machine that has the required
number of teeth in to make the well known "roll cuff" pattern, and is geared in
the usual manner to a small pinion which is attached to the ordinary machine side
spindle, at Fig. 5 and can be readily thrown in and out of operation by means of
a clutch in the usual way. When shogg mechanism is in action this pinnion runs
freely on end of shaft. I next cut the same number of teeth in a wheel that is
mounted upon the upper end of the aforesaid vertical shaft that passes through
the bed of machine, and with another vertical shaft and two small pinions connect
this wheel with the one having the same number of teeth in on the top of rib
machine; the necessary cams are now fitted upon this wheel to operate the machine
cam levers.
I then employ a clutch, or other suitable arrangement to slide upon the ordinary.
machine side spindle, this gives the required movement to the rib machine which is.
necessary for it to shog, and allows the rib and frame needles to cross each other,
or the same result may be obtained by having the teeth of frame cylinder wheel,
and wheel on machine side spindle cut at a suitable angle to give the required
twist movement for shogging; this wheel on machine side spindle being made to
slide in the same manner as the aforesaid clutch, this sliding arrangement is then
operated upon by a lever which is put in motion by cams that are attached to the
wheel fixed upon the vertical shaft upon the bed of machine.
I also construct the machine cup or dial, in two parts, which allows the front
part of trick to be recessed only so much as is required for the loops of fabric, this
gives a much greater bearing surface to the needle and jack than is obtained by.
the usual method of clearance in rib machine dials.
A further improvement consists in the special shape of rib machine cam plate
and cams, and their relation to the frame came, and the depressing cam located
outside the rib machine.
It is obvious that the foregoing method of shogging may be modified, as the
wheel on the top of rib machine might be dispensed with, and the rib machine
levers could be operated upon either directly, or otherwise, by means of cams
fixed upon the wheel that operates the shog lever; but the aforesaid method is
preferred on account of the facilities it offers for making the usual "roll" pattern
cuff and the like, in the most perfect manner, and with the least modification, as
by throwing out of operation the shogging mechanism, and fixing the necessary:
cams on rib machine wheel, it admits of being operated upon by the usual clutch
wheel and eccentric.
It will also readily be perceived that the initial motion required for the aforesaid
improvements may be obtained by other means than an intermittent or semi
revolving one, by means of quadrant as specified; as a catch wheel and catch in
conjunction with a lever, or levers and cams, or eccentric motion, would give a
similar result.
I will now proceed to describe the process of shogging, which is as follows.
The lever n Fig. 1 is lowered by means of the eccentric f, this puts out of action
the ordinary frame needles on the left hand side of machine, it also allows the rib
machine lever X to fall, this operating on the rib machine cam e puts the rib
needles out of action, and admits of the upper and lower needles on the left hand.
side of machine passing each other, this is performed by the operator when the
machine stops in the ordinary way for making the cuff, as only one feeder is
employed for this purpose; the combination of the various parts are then put in

page_text: operation for shogging the upper part of machine, so that the rib machine needles
may cross the frame needles as required; the lever n. as aforesaid that is placed
iu position by the operator, is also connected to the quadrant B, and it allows it to
fall on the lug a, which is fixed on the driving wheel A, this causes it to revolve,
and come in contact with the wheel l, that is mounted on the shogg cam wheel
shaft H, causing it to revolve in section, or intermittently, on the upper end of this
shaft is fixed a spur wheel o, having cams n. n. attached on the upper and lower
side, these cams operate on the shogg lever m, which causes said lever to have a
vertical vibrating movement a swivel lug g, is arranged on the end of this lever,
which fits into a recess on the clutch E Fig. 5, this clutch is arranged to slide on
the ordinary rib machine side spindle d, (the spindle that connects the upper and
lower part of machine) the sliding of said clutch by means of the vibrating lever,
causes the side spindle shaft to slightly revolve, or twist in a backward and
forward direction, this causes the upper and lower needles of machine to cross
each other, or shogg first to the right and then to the left; the rib machine cams.
are operated upon (so as to be in the required position for shogging and forming
the necessary pattern), by means of the lever a 1, Fig. 1 this being controlled by
the cams h. p. two other cams are arranged to operate on the lever rat c all these
four cams are fixed on the spur wheel y, that is mounted on the top of rib machine,
this wheel has the same number of teeth in as the shogg cam wheel o, and is
connected by the vertical shaft a, and pinnions p. p. so that when the shogg
wheel 0, is partly revolved by the quadrant B, the whole of these wheels are
brought into operation, and this admits of the various cams being timed so that
the needles make the required pattern, and are placed in and out of operation so as
to allow the shogg to take place; the frame cam on the right hand of machine
(which operates on the needles while the shogg is in process) is a fixture and is not
controlled in any way by the foregoing mechanism.
This shogging apparatus, or combination, is applicable to all circular knitting
machines having an ordinary rib machine with lever jacks and the usual louse
dial.
The second portion of this invention is an arrangement whereby the stopping
of the machine takes place instantaneously, when a breakage of the yarn, or empty
bobbins occur etc.
In order to carry out this improvement I erect a shaft at the back of machine,
having a number of catch or tooth wheels fixed thereon, a small bevel or inclined
clutch is also fixed on the shaft which is operated upon by a loose chain pulley
having a similar clutch on the side, this pulley is now connected by means of a
chain to a similar pulley on the driving shaft of machine. I next arrange a bar
directly over the top of these catch wheels, having as many tubes mounted thereon
as there are threads being worked by the machine. Pieces of wire are now unde
to pass freely in these tubes, and hooks, or eyes, are attached by means of cords,
or their equivalent, and these eyes being hung directly upon the yarn as it passes
to the machine needles, thus, if any of the threads break, or bobbins run empty,
these wires fall and coming in contact with the catch wheels stop them from
revolving, this causes the chain pulley to slide upon the shaft, and be disengaged
from the catch wheels; therefore I mount up in a suitable position a lever, or its
equivalent, (the pressure of which holds the chain clutch pulley in operative
position) and this is so arranged that when the sliding motion of the loose chain
pulley takes place, it comes in contact with the lever and disengages the catch,
or stop, that holds the handle of machine in operation, thus stopping the machine
instantly. This stopping device is applicable to circular knitting machines of all
kinds.
In order that the invention may be more readily understood, I will proceed to
describe it with reference to the annexed drawings, in which Fig. 1. is a front view.
of machine shewing the various parts of shogging mechanism in operative
position: A is the machine driving wheel with the lug a. fixed thereon. B is the
revolving quadrant which slides freely on the boss of machine plate. c is a

page_text: Hange that projects from the boss of quadrant, g is a slide with a foot on the end,
and is connected to the eccentric f. is the link that connects the machine cam
lever with the eccentric. n the lever that puts the left hand frame cam A. Fig. 4,
in and out of operation, and is also connected to the eccentric, and by the conjunction
of the foregoing parts to the eccentric the following results are obtained, first by
moving the eccentric to its lowest position, it lowers the rib machine cam lever
which causes the cam and needles to recede so that they do not press over, or clear,
it also causes the frame cam to fall which prevents the needles rising above the level
of the verge, and admits of this side shogging when in this position. This eccentric
also controls the quadrant B as when it is in its lowest position it allows it to fall
and coming in contact with the lug a. on driving wheel causes it to revolve at the
same rate as the machine, it will therefore readily be perceived that if the eccentric
is reversed it will lift the quadrant out of action and bring the frame and machine
needles into operative position. The spur wheel on the shog cam shaft is broad
enough to admit of the quadrant being raised out of action without altering their
relative position. H is the bearing which supports the spur wheel 1, n. the cams,
and m the shog lever, o, is the cam shog wheel, having the same number of teeth in
as the cam wheel y on the top of rib machine, these two wheels being connected by
the counter shaft a and pinion wheels
PP.
vis the rib machine depressing cam
which is made broad enough to hold sufficient jacks out of operation, (this admits of
shogging, or crossing the top and bottom needles while the upthrow cam of frame
cylinder remains in a fixed position). r is the lever which is operated upon at
point c. by means of cams d. d. fixed upon the wheel y. Fig. 3. hp are the cams
that operate upon the machine cam lever a 1. that controls the special cam c.

wheel that is fixed on the lower end of shog cam shaft. Four revolutions of
quadrant B being required to complete one revolution of wheel l.

Fig. 4 is another view of the method employed to connect the quadrant, the frame
cam, and rib machine cam, by means of levers and eccentric etc. as fully described
in Fig. 1.

shog cam wheel shewing system of connecting shog lever to sliding clutch on the
ordinary machine side spindle. A section of shog lever o shog cam wheel & cams

slide freely in grooves that are in the boss n. g is the lug that fits in the recess of
shog clutch and swivels in the end of shog lever.
Fig. 6 is an elevation of inside cam plate and cains of rib machine with jack and
needle in operative position. A is the lever or jack and needle. c the special cam.
is an ordinary cam.
Fig. 7. is a plan of inside cam plate and cams of rib machine giving an outline of
the special shape of cam plate which admits of a much greater number of jacks and
needles being held in the position known as the half course, that is, projecting as far
as possible but not to allow the loops of fabric to get over the needle latches, so
that they would turn over and press off. By this improvement I am enabled to
hold the machine cup or dial, much more rigid than has been before possible.
C. is the improved rib machine cam that is operated upon by the lever a 1. Fig. 1.
The special feature of this cam consists in being able to retain the jack and needle
that it strikes when in its lowest position until it is pressed right out, this is obtained
owing to the cam sliding in the position shewn, which causes the point of cam C. to
gain on the radial line d. this insures the positive operation of the same needle when .
the shog takes place.
Fig. 8. shews a complete section of shog clutch and wheel with the method of,
attaching and screwing same together.
