I HENRY JOHN MOSES MELLOR of A-lockton Lodge, Nottingham Machinist, do
hereby declare the nature of this invention to be as follows:-
This invention has more especially for its object to provide improved machinery for
knitting striped or plain Jerseys.
I use a cylindrical needle head carrying all round it latch needles which can be
moved up and down by cams carried by a ring which surrounds the exterior of the
cylinder. This ring also carries a third ring upon which the thread or yarn guides
are mounted.
Several yarn guides are carried by the ring and there are as many sets of cams for
raising and lowering the needles as there are yarn guides.
The cam ring is made to oscillate to and fro around the cylinder. The ring
carrying the yarn guides is carried round by friction with the cam ring but is
arrested by stops when the requisite travel in either direction has been made. This
travel is slightly greater than the distance between the yarn guides. A somewhat
greater travel is given to the cam ring to give a lead for the yarn. The consequence
is that the path moved over by the cams overlap one another and at these points
work would be pressed off some of the needles if not provented from doing so.
To obviate this we apply mechanism to these needles to prevent the loops of old
work being knocked off when no new thread has been laid on to them.
One way of effecting this is to provide mechanism to lift the needles out of work.
they being loose in the jacks to allow of their being lifted to prevent the loops on
then being knocked off when the inclines run on to the jacks.
In this way vertical stripes may be produced and where the stripes meet the
work is formed by a single thread on each needle, just as in the other parts of the
work. One needle at the meeting of the stripes having work formed on it alternately
first with thread from the thread layer used for forming one stripe and then at the
next course with thread from the thread layer used for forming the adjoining stripe.

page_text: There may be as many stripes formed in the work as there are thread layers or a
lesser number of stripes or all plain of one colour as may be desired.
Preferably I make the cams or inclines carried by the oscillating ring to act upon
two opposite arms of jacks or levers which at one end are coupled to the needle
stems.
The same means can be used for producing work for other purposes on a circle of
needles.

page_text: OT STOCKton Louge, ottingham, machst, 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 more especially for its object to provide improved machinery for
knitting striped or plain Jerseys.
I use a cylindrical needle head carrying all around it latch needles which can be
moved up and down by cams carried by a ring which surrounds the exterior of the
cylinder. This ring also carries a third ring upon which the thread or yarn guides
are mounted.
Several yarn guides are carried by the ring and there are as many sets of cams for
raising and lowering the needles as there are yarn guides.
The cam ring is made to oscillate to and fro around the cylinder. The ring
carrying the yarn guides is carried round by friction with the cam ring but is
arrested by stops when the requisite travel in either direction has been made. This
travel is slightly greater than the distance between the yarn guides. A somewhat
greater travel is given to the cam ring to give a lead for the yarn. The consequence
is that the paths moved over by the cams overlap one another and at these points
work would be pressed off some of the needles if not prevented from doing so.
To obviate this I apply mechanism to these needles to prevent the loops of old
work being knocked off when no new thread has been laid on to them.
This might be effected by providing mechanism to lift the needles out of work,
they being loose in the jacks to allow of their being lifted to prevent the loops on
them being knocked off when the inclines run on to the jacks-1 however prefer to
effect it in the manner hereinafter explained.
In this way vertical stripes may be produced and where the stripes meet the work
is formed on each needle, just as in the other parts of the work. One needle at the
meeting of the stripes having work formed on it alternately first with thread from
the thread layer used for forming one stripe and then at the next course with thread
from the thread layer used for forining the adjoining stripe. The stripes of work over-
lapping one another on one or more needles where the stripes meet. There may be
as many stripes formed in the work as there are thread layers or a lesser number of
stripes or all plain of one color as may be desired.
Preferably make the cams or inclines carried by the oscillating ring to act
upon two opposite arms of jacks or levers which at one end are coupled to the
needle stems.
The same means can be used for producing work for other purposes on a circle of
needles.
Figure 1 is a side elevation partly in section of a machine constructed to work in

page_text: the manner above described. Figure 2 is a plan view parily in section of part of the
same. Figure 3 is a diagram view on a larger scale showing the positions of the
cams and needles at one end of the movement of the cam ring G and Figure 4 is a
diagram showing the position of the parts at the opposite end of its stroke.
A is an ordinary horizontal bed carried at its ends by standards B.
C is a
circular saddle fixed to the bed. T is the needle cylinder it is kept from turning
by a pin V fixed to the saddle rising up through its bottom flange. The bottom
flange rests on the top of a screwed cylinder U so that the cylinder may be raised or
lowered according to the length of loops required to be made. T' are the needles
which are raised and lowered by jack levers R. The jack levers work in a brass
comb or tricks P fixed to the bed C. S is a fulcrum ring on which the jacks rock.
The cams for acting upon the jacks are carried by a ring G. The ring forms a
cover for the jacks and around part of its bottom edge has teeth projecting from it
to gear with a toothed rack F which is moved to and fro by an adjustable crank
motion not shown in the drawings. The cover ring G is held down by plates E fixed
to it passing under the edge of the saddle C.
H. D, are incline cams fixed to the underside of the ring G-ihey act on the two
arms of the jack levers to draw the needles downwards for knocking over the work.
I, J, are two cams which are also carried by the ring Gone on one side of the
knocking over cams and the other on the other side. They can be raised to put
them out of action or lowered to bring them into action. One is moved into
position to be in action when the ring G is turning in one direction and the other
when the ring G is turning in the opposite direction and serve to raise the needles
for yarn to be laid on to them and to allow the loops of work to pass below the
latches.
K is a friction ring embracing the exterior of the ring G and carrying yarn
guides one for each set of cams D, H. M. N. are adjustable projections from
the friction ring K. O is a stop fixed to the bed A for the projections M. N to
strike against when the ring has completed the movement required to be given to it
in one or other direction.
W is another friction ring carried by the cam G. It is held to the ring G by
screws which pass through slots Z cut in it. It carries cams X for raising and
lowering the cams to put them into or out of action. The extent of its to and
fro traverse is controlled by a projection W1 from it coming against adjustable
stops W fixed to the bed A.
The to and fro movement given to the ring K that carries the thread guides Lis
somewhat greater than that given to the ring W that carries the cams X so that
the thread guides are moved to and fro from one side of one of the needles a which
I call selvage needles to the opposite side of the next selvage needle.
The action is as follows:-
In Figure 3 the parts are shewn in the positions they are brought into at one end
of the movement of the ring G. When the ring is next moved it is moved in the
direction shown by the arrow. It then carries with it all the cams and friction rings.
Each yarn guide feeds yarn on to the selvage needle a which is next to it and on to
the succeeding needles until it has laid thread on to the next selvage needle when its
movement is arrested.
As thread is being laid on to the needles the cams raise the needles high enough
for the old loops to pass under the latches or tumbiers and the knocking over cams
draw the needles downwards until the old loops of work pass off from them, and work
is thereby produced until the friction ring W has moved as far as the stop W will
permit it and the inclined cams X are thereby stopped. The cam marked X in
figure will then have passed into the position occupied by the cam marked X* in
figure 1.
The cams being still carried onwards along with the ring Gare then
raised by the action of the incline cams X and cease to raise the next and subsequent
needles high enough for the loops on them to get under the latches or tumblers so
that the foops are prevented from coming off the needles when they are drawn
downwards by the knocking over cams D.

will have passed into the position occupied by the cam marked D* in figure 4 and

then
being in
If desired the knocking over cams DH might be put out of action immediately
after the knocking over of the work on the selvage needles a so that in their further
movement they should cease to draw the needles downwards and this might be effected
by cams carried by a friction ring in the same way that the cams
and out of action by cams X on the rings W.
are put into
Although have only shewn my invention as applied to machines for producing
plain fabrics it will be readily seen that it can be equally well applied to machines for
producing ribbed fabrics.
In place also of the ring G being oscillated and the circle of needles fixed the ring
might be fixed and the circle of needles together with the stops be oscillated to and
fro I however prefer the arrangemeni shewn in the drawing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is
1. The construction of circular knitting machines capable of producing striped work
substantially in the manner herein before described.
2. The employment of numerous yarn guides ranged at equal distances apart
around a circle of needles and either the guides or the circle of needles oscillated to
and fro to cause each yarn guide to lay its thread over a segment of the circle of
needles the segments overlapping one another and thereby producing a tubular fabric
substantially as described.
3. The combination of the cam ring Goscillating around the needle cylinder-the
yarn guide friction ring K carried along with it the friction ring W carrying cams
for regulating the action of the cams carried by the cam ring G and stops for limiting
the movement of this friction ring substantially as described and illustrated in the
drawings annexed.
