Improvements in the Manufacture of Fabrics on Circular Knitting
Frames, and in the Means or Apparatus Employed therein.
We WILLIAM BEET SCOTTORN of Roden Street in the Town and County
of the Town of Nottingham, Hosiery Manufacturer, and RICHARD HARDWICK,
of Cobden Factory, 104 Arkwright Street Nottingham aforesaid, Fleecy Hosiery
Manufacturer, do hereby declare the nature of this invention to be as follows:-
:-
These improvements have reference to certain improvements in the manufacture
of knitted fabrics on circular knitting frames and in the means or apparatus
employed therein.
In carrying out our invention in the manufacture of various kinds of hosiery on
the circular loop wheel frame we enable the operator to produce readily on
ordinary hosiery goods, a splicing thread or to make striped ornamental work such
as French neck, with one or more coloured threads at the same time that the
ordinary fabric is being made. We are able to maintain complete control over the
splicing and the striping threads which we make to pattern required.
A circular loop wheel frame of substantially ordinary and usual construction is
composed of a head or cylinder, which is supplied with bearded needles and these
needles working in conjunction with certain wheels and parts such as, the loop
wheel, the dividing wheel, the landing wheel, the presser, the knocking over wheel,
the push-back and the clearing wheel, effect the knitting, the yarn being
conveyed to the needles in the cylinder through stationary guides underneath the
loop wheel for the making of ordinary work as is well understood by framework
knitters.
or
In our improved apparatus for effecting splicing or striping we employ two
more moveable guides which are attached to levers suitably mounted which we
operate by suitable wheels, pattern surfaces or studded chains and we also employ
peculiarly formed shears, which are applied between the loop wheel and the
dividing wheel, for the purpose of cutting off threads entered through the moveable
guides, when those threads are not required for striping.
These parts may be arranged to effect the cutting off of these threads at each
revolution, or at any part of a revolution as may be desired.
The form of the guides may be a centred blade narrowing towards its operating
end and being provided with eyes or like parts for passage of the thread at such
end and at a short distance therefrom.
The scissors may consist of one blade of substantially straight form inclining
from the centre pin towards the point or end and forming a cutting edge whilst the
other blade is cranked so that the cutting portion beyond the centre pin is
substantially parallel with that part of the other blade then the cranked part
crosses the straight blade and the arm again is substantially parallel with the other
straight arm which straight arm may be relatively the fixed one and the cranked
arm be the moveable one operated by the mechanism.

We WILLIAM BEET SCOTTORN of Roden Street in the Town and County of
the Town of Nottingham Hosiery Manufacturer and RICHARD HARDWICK, of
Cobden Factory, 104 Arkwright Street, Nottingham aforesaid, Fleecy Hosiery
Manufacturer 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 :-
These improvements have reference to certain improvements in the manufacture
of knitted fabrics on circular knitting frames and in the means or apparatus
employed therein.
In carrying out our invention in the manufacture of various kinds of hosiery ou
the circular loop wheel frame we enable the operator to produce readily on
ordinary hosiery goods, a splicing thread or to make striped ornamental work such
as French neck, with one or more coloured or other threads at the same time
that the ordinary fabric is being made. We are able to maintain complete
control over the splicing and the striping threads which we make to pattern
required.
A circular loop wheel frame of substantially ordinary and usual construction is
composed of a head or cylinder, which is supplied with bearded needles, and these
Deedles working in conjunction with certain wheels and parts such as, the loop
wheel, the dividing wheel, the landing wheel, the presser, the knocking over wheel,
the push back and the clearing wheel, effect the knitting, the yarn being
conveyed to the needles in the cylinder through stationary guides underneath the
loop wheel for the making of ordinary work as is well understood by framework
knitters.
In our improved apparatus for effecting splicing or striping we employ two or
more moveable guides which are attached to levers suitably mounted which we
operate by suitable wheels, pattern surfaces, or studded chains and we also employ
peculiarly formed shears, which are applied between the loop wheel and the
dividing wheel, for the purpose of cutting off threads entered through the movable
guides, when those threads are not required for striping.
These parts may be arranged to effect the cutting off of these threads at each
revolution, or at any part of a revolution as may be desired.
The form of the guides may be a centred blade narrowing towards its operating
end and being provided with eyes or like parts for passage of the thread at such
end and at a short distance therefrom.
The scissors may consist of three blades two being of substantially straight form
inclining from the centre pin towards the point or end and forming a cutting edge
whilst the other blade is cranked so that the cutting portion beyond the centre pin
is substantially parallel with that part of the other blade, then the cranked part
crosses the straight blade and the arm again is substantially parallel with the other
straight arm which straight arm may be relatively the fixed one and the cranked

DESCRIPTION OF THE DRAWINGS.
as is used for enticing only

page_text: taken at right angles to Fig. 7.
Figs. 9 and 10 show face and edge views of the cam D, Fig. 2, that works the
lever C; Fig. 7, that operates the scissors.
Fig. 1 shows a face view of lever E.
Fig. 12 is a plan and Fig. 13 is a side view of the guide a. Fig. 1, referred to.
Figs. 14 and 15 are sectional and front views of the brush band attachments.
Figs. 16 and 17 are side view and plan view respectively of the cylinder d and
cam D which works the chain which acts on lever E Fig. 11 and lever Con
Fig. 1.
The scissors A consist of three blades, two of which are stationary, the middle
one being moveable and working between the two stationary ones upon a pin or
rivet which passes through all three blades, the closing of the scissors for cutting
the thread being done by the cam D acting on the lever C as the cylinder
revolves. Each time the cam D has passed the lever C the scissors are
immediately opened by a spring attached to the moveable blade at that end
opposite to the cutting end-a hole A' being provided to receive the end of the
spring.
The lever C is so placed that the end of the arm at (1) rests underneath the end
of the moveable blade of the scissors and near the spring. The arm (2) is operated
by the camn D so that upon being moved by the said cam it raises up the arm (1)
which thus closes the scissors. As soon as the cam D has left the arm (2) the
scissors are opened by the spring, and the action of the opening of the scissors
brings the lever back into position for the cam D to again operate upon at the next
revolution of the cylinder. The scissors A are thus made to cut the thread by the
action of the lever C, said lever being worked by the cam D Fig. 2 which is
attached to the cylinder d.
'
For making stripe and tuck goods we use the two moveable guides B B which
are operated as follows: Each of the guides B carries a thread used in making the
fabric, one guide being in action at the time the other guide is out of action.
When in action the guide is up and when out of action it is down, being held down
by the lever E, which lever is forced up by the action of small pieces of iron
known in the trade as bits, attached to the links of a chain which passes around a
drum, and is moved forward one link at each revolution of the cylinder d by
suitable means such as a rack wheel on the drum and a cam D¹ on the cylinder.
The bits on the chain are brought into contact with the ends of the levers E as
the chain is worked round, and these bits may be put on at any of the links which
may be desired and as many as may be desired for producing a sufficient number
of courses of striping or splicing. When the lever E is released from the pressure
of the bit by the chain being racked forward it is drawn down upon one of the
guides by a spring which is attached to the said lever E thus forcing a guide B
downwards out of action, the other guide being released by means of an attached
spring is brought into action.
The guides B are shown in side view by Fig. 5, the guide which is "up" at the
forward or right hand end being in the position when in action, and that one
which is "down" being in the position when it is "out of action."
The springs B which draw the guides into action upon their being released by
the levers E are small elastic springs attached to the ends, a small notch B' being
provided for the purpose, see Fig. 5

page_text: Two levers. E are provided, one for each guide, working side by side, operated
on by bits placed in suitable positions on the chain. Each guide B carries a thread,
one for ground work and the other for splicing, and as either of these guides go out
of action, the thread is cut off by the shears, and on the guide being brought into
action the thread which it carries is immediately taken into work by the ordinary
loop wheel.
For splicing we use the same, or similar guides see Figs. 1, 12 and 13. The
thread is held by means of the spring a in the carrier a, and when released by the
lever c the brush & carries it into the loop wheel said lever c being operated in a
similar manner to lever E. We can tuck, stripe, or splice or combine all three at
one or any part of each revolution of the cylinder d.
с
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 :
In the manufacture of fabrics on circular knitting frames:
1. The combination or arrangement and use of the guide that carries the splicing
or striping thread, the brush which carries the splicing or striping thread into the
loop wheel on its release by the action of the lever c upon the guide a and the cam
for operating said lever, all substantially as set forth and illustrated by the
drawings.
2. The construction and arrangement of the splicing or striping thread guide a,
as set forth.
3. The construction and operation of the brush bas and for the purpose set
forth.
4. The construction or arrangement and use of the shears A and guides B,
substantially as and for the purpose set forth.
5. The method of and means for the production of striped and spliced fabrics
either plain or tucked, and whereby fabrics either plain or tucked, striped or
splice can be produced in all or any part of a revolution of the cylinder, all
substantially as set forth.
