Fabrics, and in the Means or Apparatus Employed therein.
We THE NOTTINGHAM MANUFACTURING COMPANY, LIMITED of Station
Street in the Town and County of the Town of Nottingham, and JOHN GROVEN
of 94 Leicester Road, Loughborough, in the County of Leicester, Manager, and
JAMES WHATNALL of 5 Selbourne 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:-
The object of the invention is to produce a novel and ornamental appearance to
knitted fabrics by the introduction of striping and plating on straight bar rib
machines and to adapt means or apparatus for the production of the same.
In order to effect this we apply apparatus, which may conveniently be substantially
the ordinary striping and draw back striping tackle, or only a modification thereof
to the present purpose, to the "cotton or other straight bar ribbed machine and
we connect the "royal rib or other equivalent appliance, wherein the machine
needles can be mispressed, or tucked at alternate or other courses as may be
arranged for.
"
The following is a description of one arrangement of mechanism by means of
which the object of our invention may be effected; viz.
We apply a striping wheel, which may be of substantially ordinary description,
upon the end standard of the machine at the back, which is racked every course as
usual (say) by a cam and levers operated by the main shaft.
This striping wheel carries a chain or equivalent, having upon it three, or other
number of sets of inclines, or risers, which inclines operate a corresponding number,
say, three levers, connected with the striping star wheel, or the device equivalent
thereto.
The draw back lever and the royal rib star wheel, or its equivalent device, are
operated alternately, or as may be required.
To
The striping wheel is mounted on a suitable bracket or support affixed to the
back of the end standard of the machine. A rocking shaft on the back rail of the
machine is caused to receive motion from a cam or like part on the main shaft
through a lever or such like part carrying a link or connection to a rocking lever
having a clawker engaging the teeth on a striping wheel. In changing the carriers
for striping a lever is raised by an incline or chain of the said striping wheel
connected through a link with a small lever which regulates the motions of and at
suitable times allows a clawker to come in contact with and rack a star wheel one
tooth; which changes the carriers in or substantially in the ordinary way.
make the ornamental or plated work we have to introduce another thread or threads
at every other course or at selected courses. To do so we require a draw back
course effected say at every third course. This is effected by a lever mounted on
the said bracket which is raised by an incline on striping wheel chain this causes a
lever to be thrown up or rocked and it thereby forces a link forward letting a
clawker mounted on a rocking lever come into contact with a stud on an L or
equivalent lever which forces other levers under the needle bar arms in the usual
way.
To make use of "royal rib" mechanism in connection with the striping wheel
we mount a lever on the aforesaid bracket which lever engages an incline on the
striping chain, raising another lever and forcing a link forward letting a clawker,

mounted on a rocking lever engage in the teeth of another stair wheel. This star
wheel gives a rocking motion to a lever and through a link imparts a backward
and forward motion to a lever which shogs the truck on the machine slide lever
arm in and out of action, to press, or mispress or tuck the needles as required.
To make the same fabrics on a rib top machine we use appliances which may be
substantially, or modifications of, the same but with an additional star wheel to lift
the finger out of action whilst the draw back course is made which operation may
be effected substantially as described and shewn in the Specification of a Patent
granted to the present pplicants and numbered 1776 of February 4th of the
year 1887 but with such other modifications and connections as may be required. to
effect the present purposes.

page_text: having 'say three sets of inclines a, a, a, which inclines, or risers, operate a corre-
sponding number of levers J. O. V. connected with the striping star wheel, the
draw back lever, and the "royal rib" star wheel, respectively, being operated
alternately, or as may be required. In changing the carriers for striping, the
lever J is raised by an incline on the chain of the striping wheel. A connected
through a link K with a small lever L which regulates the motions of and at
suitable times allows the clawker M to come in contact with and rack the star
wheel N one tooth which changes the carriers in, or substantially in, the ordinary
way. To make the ornamental or plated work we have to introduce another thread
or threads at every other course or at selected courses. To do so we require a
draw back course, effected say at every third course. This is effected by a lever O
mounted on the said bracket B which is raised by an incline on the striping wheel
chain a; this causes a lever P to be thrown up or rocked, and it thereby forces a
link Qforward, letting a clawker R, mounted on a rocking lever S, come into
contact with a stud on an lever T, which forces the levers U under the needle
bar arms in the usual way.
To make use of "royal rib" mechanism in connection with the striping wheel A
we mount a lever V on the bracket B which lever engages an incline on the striping
chain, raising the lever W, and forcing a link X forward, letting a clawker Y,
mounted on a rocking lever Z, engage in the teeth of a star wheel A'. This star
wheel A¹ gives a rocking motion to a lever B, and through a link C₁ imparts a
backward and forward motion to a lever D' which shogs the truck on the machine
slide lever arm, in, and out of action, to press or mispress or tuck the needles as
required.
To make the same fabrics on a rib top machine, we use appliances which may be
substantially, or modifications of, the same but with an additional star wheel as N,
to lift the finger L2 out of action whilst the draw back course is made, which
operation may be effected substantially as described and shewn in the Specification
of a Patent granted to the present Applicants and numbered 1776 of February 4th
of the year 1887 but with other modifications and connections as may be required to
effect the present purposes.
In some cases an additional shogging movement of the machine presser truck
when making the draw-back may be introduced.
This will be effected by the same appliance and at the same time as the "slide
truck is shogged in plating and will prevent the odd loops of colour coming up
upon the face of the fabric.
The shogging of the truck will mispress the machine needle bar and therefore
the loop will be kept under the needle beard.
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 method of and means or apparatus for producing novel and ornamental
effects in knit fabrics by the introduction of striping and plating on straight bar
ribbed knitting machines substantially as set forth.
cotton" or
2. The combination or arrangement and use with the ordinary
straight bar fashioned ribbed hose, or ribbed top, machine of ordinary striping and
draw back stripe tackle and the connection of the appliance, wherein the machine
needles can be mispressed or tucked at any desired course, all substantially as and
for the purpose set forth.
3. In a straight bar fashioned ribbed hose or ribbed top machine the combination
or arrangement and use of a striping wheel, three or other suitable number of
inclines on a chain, or equivalent device, for operating levers or like parts, actuating
or connected with the striping star wheel, the draw back lever or the royal rib
star wheel alternatively as may be required, in manner and for the purpose substan-
tially as set forth.
