Improvements in or relating to Knitting Machines.
1, JOHN LANGHAM of Causeway Lane, Leicester, Fancy Hosiery manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention bas reference to knitting machines and is particularly applicable to
machines having what are known as parallel needle beds, such as the "Lamb" frames,
and the object of the invention is to effect certain improvements in the apparatus for
laying the threads onto the needles, so that threads of different qualities may he
employed in the process of knitting with the result that one of the threads, preferably
that of inferior quality, may become "sandwiched" in the fabric produced and its
presence only detected by a close examination of the said fabric. To effect this result
I may if necessary utilise the present thread carrier or carrier needle and around the
eye or hole therein I form a preferably approximately semi-circular slot or eye the
onter or terminating ends of which may be on a level with the ordinary eye or hole.
Now if the thread which it is desired to come uppermost and form the face of the
fabric is allowed to feed through this semi-circular slot on to the needles it has a
certain amount of play and changes its position at every traverse of the thread carrier
to enable it to get the leading position and keep in advance of the thread feeding
through the ordinary eye.
I may also effect the same result by the employment of two thread carriers, each
carrying a different thread, and acting in concert with certain stops or equivalent
mechanism fixed on suitable parts of the frame to shorten or lengthen or regulate the
traverse of the carrier as may be desired.

COMPLETE SPECIFICATION.
Improvements in or relating to Knitting Machines.
I, JOHN LANGHAM of Causeway Lane, Leicester, Fancy 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:
This invention has reference to knitting machines and is particularly applicable to
machines having what are known as parallel needle beds, such as the Lamb' frames
and the object of the invention is to effect certain improvements in the apparatus for
laying the threads on to the needles, so that in the event of threads of different qualities
being employed in the process of knitting, one of the threads becomes 'sandwiched'
in the fabric produced, or in other words is caused to lie behind the stitches forming
the ribs, and its presence can only be detected by a close examination of the said
fabric.
To effect this result I may if necessary utilize the present thread carrier or carrier-
needle and around the eye or hole therein I form a preferably approximately semi-
circular slot or eye the outer or terminating ends of which may be on a level with the
ordinary eye or hole.
In the accompanying drawings I have shown an apparatus similar to that above
described for producing sandwiched fabric and so much only of the parts of a
knitting machine as is necessary to enable this invention to be understood.
Figure 1 represents in front elevation and Figure 2 in side elevation a thread carrier
or carrier-needle constructed according to this invention, and shown fixed to the frame.
Figure 3 is a perspective view showing the underside of the thread carrier.

page_text: A is the thread carrier or carrier-needle which is fixed to the frame in the usual
way, B is the ordinary eye or opening, and C is the additional or approximately
semicircular slot which forms the main feature of this invention.
$
For producing sandwiched' fabrics it is necessary that the thread which is to form
the face or wearing surface should take the lead at every iraverso of the thread carrier.
For this purpose the principal thread is allowed to feed through the hole B, and the
thread which is to become sandwiched in the fabric feeds through the slot C.
For purposes of illustration suppose the thread carrier were travelling in the direction
indicated by the arrows the sandwiching thread would be at the end D of the slot C
and at the return traverse of the thread carrier it would be at the opposite end E of
the slot (so that in each instance it would be behind the thread feeding through the
hole B.
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 I
claim is
In "
a Lamb or similarly constructed knitting machine a thread carrier or carrier-
needle provided with the usual eye or opening B and with another eye or slot such
as C substantially as and for the purpose herein described and illustrated in the
accompanying drawings.
