We, THE NOTTINGHAM MANUFACTURING COMPANY Limited of Station Street in
the Town and County of the Town of Nottingham, and JOHN GROVES of 4 Burton
Street, Loughborough in the County of Leicester, Manager, and JAMES WHATNALL
of 27 School Street, Loughborough aforesaid, Mechanic, both in the employment of
the said Nottingham Manufacturing Company Limited, do hereby declare the nature
of this invention to be as follows:-
These improvements relate to knitting machinery, particularly those classes of
machinery known in the trade as Cotton's frames, or machinery made substantially
in accordance therewith, and have for their object to provide means for effecting
marking of the web or material produced with letters, marks or other openwork
pattern, variable at will, by only easy changes of removable parts without necessarily
causing stoppage of the machine for the purpose.
On the ordinary shogging lever shaft is a short arm similar to the ordinary arm in
use in narrowing, and provided with a stop which engages with inclines on a shogging
pattern wheel affixed to a ratchet wheel mounted frictionally on a short shaft carried
by a bracket affixed to the front rail of the machine.
These inclines on the shogging pattern wheel are removable and exchangeable
for others, according to requirements of pattern of openwork to be produced,
whether that be, say, a simple eyelet hole or a diamond of such holes, a letter, a
leaf, a flower, a monogram or other openwork pattern.
The ratchet wheel is operated by a clawker carried by a stud projecting from an
arın mounted on the said shogging lever shaft. On this arm between the said shaft
and the clawker stud is mounted a truck or bowl which presses against a cam under
the influence of a spring and is moved to and fro in the revolution of said cam. This
cam is mounted on the main shaft of the machine. The ratchet wheel being affixed to
the pattern wheel and being mounted on the same shaft causes the same to revolve
and in its revolution the rises on the surface thereof (arranged to the pattern of
eyeletting for the time being desired) engage and move the stop on the short arm
and move that arm with a rocking motion causing shogging of the main shaft,
putting the said cam into engagement with two bowls mounted on the divided or
forked arms of a lever centred on a bracket mounted on the main framing, with
capability of rocking as it is moved by said cam; the fork of this lever also carries
a stud on which is mounted another stud at right angles thereto on which again are
mounted two clawkers, these clawkers pass up and between guides on either side of
a dependent arm of an angular bracket on which is also frictionally mounted a
pattern wheel, the rises or inclines on which are adapted to the pattern desired to be
produced. The rising of the clawkers causes one of them to engage the ratchet
mounted on the same axis as the point pattern wheel and affixed thereto, and to move
said ratchet wheel one tooth, which causes a variation of extent of motion given to
the nose of the bolt which carries the bracket on which is formed a projection which
engages between two collars on the rod carrying the holders or fingers in which are
borne the point or points in an adjustable sliding manner by which such points can be
slidden in or out of operation as required.
The nose of the bracket is borne to this pattern wheel by spring pressure, or the
point may be of the ordinary fixed description.
When it is not desired to have the marking tackle in operation a projecting piece
mounted on the finger is turned a certain distance when a spring operates to hold the
point parts raised and out of operation by the bracket of the bolt, by reason of the

page_text: .
projection then lying in a space formed between the collars wide enough to admit of
its traversing to and fro inoperatively.
In the return or downward motion of the clawkers the other clawker pulls the
ratchet wheel another tooth, moving the pattern wheel one rise or incline, which is
thereby made ready for the next motion in the pattern.
On the dependent arm is also mounted a rotatory stop piece which can be turned
so as to come against and put and keep out of operation the clawkers from their
pattern wheel, and thereby the eyeletting points are left idle as long as may be
desired.
The clawkers are kept to their work by means of springs in the ordinary manner.
Considerable variation in arrangement of the parts may be effected without deviation
from the essential features of the invention.
By these means by simply removing one or more of the removable risers on the
shogging pattern wheel and altering the motion produced thereby and by changing
the point wheel any variations of the marking to be produced may be effected during
the operation of the machine in making other portions of the fabric.

Improvements in Knitting Machinery.
We THE NOTTINGHAM MANUFACTURING COMPANY Limited of Station Street in
the Town and County of the Town of Nottingham, and JOHN GROVES of 4 Burton
Street, Loughborough in the County of Leicester, Manager, and JAMES WHATNALL
of 27 School Street, Loughborough aforesaid, Mechanic, both in the employment of
the said Nottingham Manufacturing Company Limited, 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 relate to knitting machinery, particularly those classes of
machinery known in the trade as Cotton's frames, or machinery made substantially in
accordance therewith, and have for their object to provide means for effecting marking
of the web or material produced with letters, marks or other openwork pattern, vari-
able at will, by easy changes of removable parts without necessarily causing stoppage
of the machine for the purpose.
On the ordinary shogging lever shaft is a short arm similar to the ordinary arm in
use in narrowing, and provided with a stop which engages with inclines on a shogging
pattern wheel affixed to a ratchet wheel mounted frictionally on a short shaft carried
by a bracket affixed to the front rail of the machine.
These inclines on the shogging pattern wheel are removable and exchangeable for
others, according to requirements of pattern of openwork to be produced, whether that
be, say, a simple eyelet hole or a diamond of such holes, a letter, a leaf, a flower, a
monogram or other openwork pattern.
The ratchet wheel is operated by a clawker carried by a stud projecting from an
arm mounted on the said shogging lever shaft. On this arm between the said shaft
and the clawker stud is mounted a truck or bowl which presses against a cam under
the influence of a spring and is moved to and fro in the revolution of said cam. This
cam is mounted on the main shaft of the machine. The ratchet wheel being affixed
to the pattern wheel and being mounted on the same shaft causes the same to revolve
and in its revolution the rises on the surface thereof (arranged to the pattern of eye-
Tetting for the time being desired) engage and move the stop on the short arm and
move that arm with a rocking motion causing shogging of the main shaft and thereby
putting a cam mounted thereon into engagement with two bowls mounted on the
divided or forked arms of a lever centred on a bracket mounted on the main framing,
¨with capability of rocking as it is moved by said cam; the fork of this lever also

page_text: carries a stud on which is mounted another stud at right angles thereto on which
again are mounted two clawkers, these clawkers pass up and between guides on either
side of a dependent arm of an angular bracket on which is also frictionally mounted
a pattern wheel, the rises or inclines on which are adapted to the pattern desired to
be produced. The rising of the clawkers causes one of them to engage the ratchet
mounted on the same axis as the point pattern wheel and affixed thereto, and to move
said ratchet wheel one tooth, which causes a variation of extent of motion given to the
nose of the bolt which carries the bracket on which is formed a projection which
engages between two collars on the rod carrying the holders or fingers in which are
borne the point or points in an adjustable sliding manner by which such points can be
slidden in or out of operation as required.
•
The nose of the bracket is borne to this pattern wheel by spring pressure.
Or the points may be of the ordinary fixed description.
When it is not desired to have the marking tackle in operation a projecting piece
mounted on the marking rod which also carries the finger is turned a certain distance
when a spring operates to hold the point parts raised and out of operation by the
bracket of the bolt, by reason of the projection then lying in a space formed between
the collars wide enough to admit of its traversing to and fro inoperatively.
In the return or downward motion of the clawkers the other clawker pulls the
ratchet wheel another tooth, moving the point pattern wheel one rise or fall in incline,
which is thereby made ready for the next motion in the pattern.
On the dependent arm is also mounted a rotatory stop piece which can be turned
so as to come against and put and keep out of operation the clawkers from their
pattern wheel, and thereby the eyeletting points are left idle as long as may be
desired.
The clawkers are kept to their work by means of springs in the ordinary manner.
Considerable variation in arrangement of the parts may be effected without devia-
tion from the essential features of the invention.
By these means by simply removing one or more of the removable risers on the
shogging pattern wheel and altering the motion produced thereby and by changing
the point pattern wheel any variations of the marking to be produced may be effected
during the operation of the machine in making other portions of the fabric.

Cotton" frame as is sufficient to indicate the application of the invention.
Fig. 2 is an end elevation of apparatus.
Fig. 3 is a cross section of the same taken on the line X-X of Fig. 1.
Fig. 4 shews an edge view of the ratchet wheel and pattern wheel i frictionally
secured thereto.
Fig. 5 is a front view of the arm g carrying the bowl and clawker g² separately.
Figs. 6, 7 & 8 shew edge, front and back views of the ratchet wheel u¹ and point
pattern wheel v frictionally secured thereto separately.
A indicates a part of the main framing of a "Cotton" machine a is the main
shaft, to which motion is communicated by means of gearing driven from a pulley
shaft, not shewn which may be arranged in the usual manner.
On the shaft a is
mounted the ordinary shogging cams & b having surfaces 123 and 4 with which
engages the bowl c mounted on the arm c¹ affixed to the shogging lever shaft d, carried
in brackets from the main framing A.
The arm also carries a short axis c² on which is mounted the bowl c³, which
bowl is operated by the cam surface & affixed to the portion 61 of the shogging
cam. On the main shaft a is also mounted the cam e which engages with a bowl f
carried on a pin f¹ held in a slot formed in the arm g by means of a screw nut, so
that by adjustment of the position of said pin f¹ in its slot the extent of movement
of the clawker o² can be regulated as it is operated by the arm mounted on the

page_text: shogging lever shaft d. The arm g at its upper end carries a stud g¹ upon which is
mounted the clawker g² which actuates a ratchet wheel carried on a short axis h¹
borne by a bracket 2 secured to the framing A. On the axis is also mounted the
pattern wheel i secured frictionally to the ratchet wheel h. To the wheel i are attached
small plates their number and arrangement and position being adjustable according
to the particular marking of the web required.
Near the left hand end of the shaft à is affixed a cam j which operates a bowl kl
mounted upon an axis secured to a forked arm k swinging on its axis k³ borne by a
bracket bolted to the framing A.
The bowl affixed to the upper limb of the fork k ordinarily runs on the surface j¹
thereby supporting the forked arm k and co-operating parts.
is another bowl similar to the bowl and mounted on the other limb of the
fork k.
"
At the outer end of the upper limb of the forked arm k is mounted a stud kº on
which is mounted the barrel on which is formed an arm k³ carrying the hollow
bearing for the axis on which are mounted the hollow ends of the clawkers l
which pass up between guides m¹ secured to the downwardly projecting end m
of the bracket m the other portion being affixed to another bracket n carried by
the main framing A. In a recess in this bracket n the bolt o slides, carrying the
bracket o and projection o², as ordinarily provided for "narrowing," p is the
marking" rod on which are affixed two collars pl p² (which may be like those
usually secured to the narrowing rod q) between which the projection o operates.
The rod p carrying the finger with its point has at its end a short arm p₁ which
is constantly drawn upon by the spring p³ connected to it at one end whilst at its
other end this spring is connected to the upright rod p. The extent of inward
motion of the finger rod in the rotation of the axis p and parts borne thereby is
regulated by the stop pieces which bears against the narrowing rod g. The rods p
and are carried by a series of brackets distributed along the rod t one only of
which is shewn whilst the rod t itself is mounted in bearings mounted on the ends
of curved arms 2 mounted on the shaft t³ carried by the main framing A.
The bracket m carries a stud u which forms the axis of motion for and supports the
ratchet wheel u¹ frictionally secured to the point pattern wheel v. This wheel has
a cam surface or series of rises v¹ formed on its periphery and so arranged that the
rises give more or less motion to the nose piece of which has capability of motion only
to and from that surface v¹ the normal tendency being to press thereto by reason of a
spring of attached to the projection o² at the end of the rod or bolt o, of which bolt
the nose o¹ forms one end whilst the other end of the spring o³ is attached to the
bracket n.
This projection o² presses against the collar p² of the marking rod p and
the movement of that rod determines the distance of traverse of the fingers and
points relatively to the needles w and thereby the needles over which the thread is
lifted by the point and consequently the position of the holes or marks produced
in the web, this primary determining influence being the extent of rise or radial
distance from the centre of the wheel of the arc or portion thereof for the moment
acting against the nose end of the bolt o.
201
The rotation of the cam 62 by the shaft a moves the bowl c³ and the arm c¹ is rocked
outwards lifting the bowl c off the surface 2 of the shogging cam b on to the surface 3
until on further rotation of the cam b¹ the bowl c runs on to the working surface 4,
the shaft a being shogged towards the right hand in the ordinary manner.
The rotation of the shaft a also causes the came to press the bowl outwards
carrying with it the arm g and causing the clawker g² engaged in the teeth of the
wheel to rotate that wheel one tooth, and the pattern wheel i, being frictionally
secured to the wheel it is simultaneously rotated.
The shaft & is partially rotated by the movement of the arm c¹ when pressed away
by the cam surface 62 of the double cam 61 63 acting on the bowl c³, and one or other
of the studs or projections, (adjustably affixed by screws applied in one or other
of the tapped holes in the side of the wheel i), is brought over the upper side of the

page_text: surface
stud d', carried by an arm d² mounted on the said shaft d, and this shaft d is thereby
held in its partially rotated position, and the bowl c maintained in contact with the
of the cam b' after the shogging of shaft a has heen effected. The distances
apart and adjusted positions of these projections regulate the times and recurrence
of the shogging of the shaft a by the cam bb and thereby the distance apart of the
markings or holes lengthwise of the web, (the distinces apart of the markings on the
width being regulated by the point pattern wheel v)..
The shogging of the shaft a towards the right hand of the machine, (Fig. 1), causes
the cam j to operate the bowl k and raise the clawkers 11, the one arm of the clawker /
in its upward movement engaging with the teeth on the wheel ', and rotating it and
the pattern wheel v attached to it.
The rotation of the wheel e causes a movement of the bolt o towards the right hand,
the amount of such movement as already explained determining the height of the
particular cam surface v¹ which abuts against the nose piece o¹ of the bolt for the time
being.
The upward and downward motions of the point are obtained in manner similar
to that ordinarily employed for effecting like movements of the narrowing points in
Cotton's frames at present in use.
Further rotation of the cam j allows the bowl k to again run on the smaller
surface of the cam, and the part j now bears downwards upon the lower bowl k
causing the clawkers to descend, the other arm of the clawker 1, before inoperative,
pulling the ratchet wheel u one tooth to the left hand so causing another rise or
incline v to bear against the nose piece o' ready for the next motion required in the
formation of the pattern. The clawkers are held to the ratchet wheel ¹ by the
spring 12.
When it is required to have the marking apparatus out of operation a rotatory stop-
piece m mounted on a stud m³ carried by the arm m² of the bracket m, is turned so
as to bear against the clawkers and keep them from operating the ratchet wheel u¹
(as shewn by the dotted lines Fig. 1); and the points are kept out of the way for
the time being by the short arm being turned so that the stop pieces comes against
the bar t and is held back by the spring p³ (as shewn by the dotted lines Fig. 2).
When thus held back the projection o² lies in the wider space between the collars p¹ p³
so that movement of the marking tackle is prevented.
Rotation of the pattern wheel i at the completion of each operation of marking is
suspended and unnecessary friction when the marking apparatus is out of use is
avoided by a filling piece 3 screwed to the wheel i coming under the clawker ² to
lift it out of action this filling piece covering the space between two adjacent teeth on
the ratchet wheel h so that when this part so comes under the clawker g the clawker
will fail to catch the teeth of the wheel h and that wheel will cease to be rotated.
When it is desired to put the marking apparatus in operation a slight turn is given to
the wheel so as to clear the clawker of the filling piece by hand or a connection
with a rotating or other part carried by the machine.
The bowls cand may be borne to their respective cam surfaces by springs in the
ordinary or other convenient manner.
As shewn in the drawing two sets of projections i' are shewn on the wheel i, to
form two markings on the web, but the number and position may be varied so that
only one, or three, or other number of different markings may be effected on the
material. The number of teeth on the wheel h may likewise be increased or decreased
according to whether a faster or slower motion of the wheel is required.
The point pattern wheel is shewn here as being formed to put in three distinct
sets of markings, but the number of such markings may be varied by variations in
the number and height of the rises or inclines v', the number of teeth on the wheel u'
being similarly altered by the number of the inclines &³.
The clawkers are adjusted to suit any other such ratchet wheel by means of
the adjustable angle pieces screwed to the bracket m by set screws 2² 2³ working
in slots,

page_text: 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 :-
1: The combination or arrangement and use with parts of knitting machinery of
marking apparatus for effecting inarking of the web or fabric produced with letters,
marks or other openwork pattern, variable at will by easy changes of removable parts
(such as point bars or pattern wheels) and capable of being thrown out of operation
without necessarily causing stoppage of the machine, substantially as herein described
and shewn.
"
2: The combination with knitting machinery, of the "Cotton or straight frame
type, of marking apparatus, capable of alteration for effecting variation of the
markings in the fabrics produced as described or of being put out of operation
without necessarily stopping the machine, substantially as described.
"
3: The combination with a "Cotton or like knitting frame of marking apparatus.
capable of coöperating with the parts of such frame or disconnection therefrom at will
and being capable by easy change of removeable parts controlling the movements of
the marking points of effecting variation in the marking effected substantially as set
forth.
4: In a knitting machine, of the "Cotton" or like type of straight frame the
combination of the ordinary main shaft shogging lever shaft cams and bowls, or their
equivalents, with the variable pattern wheel i and parts coöperating therewith to effect
or stay the movements of the changeable pattern wheel for controlling the
movements of the parts operating the marking point or points coöperating with the
needles to effect the marking of the fabric substantially as described and shewn.
5: In a knitting machine of the "Cotton or like type a stud as d¹ mounted on
the shogging lever shaft d, a pattern wheel i, ratchet wheel h and means of rotating
the same, clawkers and means of operating the same combined with a pattern
wheel and ratchet wheel u¹ operated by said clawkers, and parts for operating and
