PROVISIONAL SPECIFICATION.
An Improved Needle for Knitting Machines.
FREDERICK WILLIAM PARE 20 Waterloo Road Nottingham Lace Manu-
facturer do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved latch needle of the kind used in latch
needle knitting machines, the improved needle being applicable to all machines in
which the ordinary needle can be used, and is particularly applicable to those
machines in which it is required to throw the needles out of action without
removing the loops from the same.
When an ordinary needle is thrown out of action, the loop on the same passes
below the latch and when the needle is returned into action the loop passes over
the end of the same unless means are provided for keeping the latch open so as to
allow the loop to pass over the open latch into the hook.
Now the object of this invention is the construction of a needle, which may be
thrown in and out of action and retain the loop without the use of additional
means. This is accomplished by providing the needle with two pivotted latches so
arranged that for ordinary knitting the end latch works as usual. When the
needle is thrown out of action the loop passes both latches, and when the needle is
returned to its normal position the loop lifts the second latch on to the top of the
first latch and passes over the same into the hook.

FREDERICK WILLIAM PARE 20 Waterloo Road Nottingham Lace Manu-
facturer 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 :-
In
This invention relates to an improved needle for latch needle knitting machines,
the said needle being particularly applicable to machines in which the needles are
thrown out of action by raising the needle neb above the path of the knitting cam
and into action by lowering the needle neb into the path of the knitting cam.
this kind of knitting machine, the needles after being thrown out of action have to
be thrown into action again when the thread carrier and knitting cam are in a
particular relative position with regard to the needle, otherwise, the loop would
either close the latch or pass over the end of the needle.
Now the object of this invention is the production of a needle which may be
thrown in and out of action without reference to the relative positions of the
knitting cam and thread carrier.
A needle constructed according to this invention is provided with two latches so.
arranged that the upper latch when plain knitting is being made acts in the usual
way.
When the needle is raised out of action the loop passes the lower latch, and

page_text: when the needle is lowered into action again, the loop lifts the lower latch on to
the upper latch, thus allowing the loop to pass into the hook of the needle.
In the accompanying drawings
Fig. 1 is an elevation of a needle showing the relative position of the latches
during ordinary knitting, and
Fig. 2 is an elevation of a needle showing the relative position of the latches
when the needle is being lowered into action.
The needle is of the usual construction so far as the hook a and upper latch b
are concerned. The needle shank is also reduced in size at c to allow of the loop
getting under the latch in plain knitting. Below the part o the needle is enlarged
at d and slotted to receive the second latch e which is pivotted in the same way as
the upper latch, the end of the slot acting as a stop to limit the motion of the
latch e. The enlargement at d is longer than the enlargement g'so as to cover the
latch e which is shaped to lie on the end of the latch b.as shown at Fig. 2 and not
exceed at its extreme width.h, h, the extreme width.k, k, Fig. 1. Below the part d
the needle is reduced in size at 1-to allow of the loop getting under the latch e.
With a needle constructed according to this invention ordinary or plain knitting
is produced in the usual way by the last formed loop passing below the latch,b, and
-on its return lifting the latch and passing over the end of the needle to form a
new loop. When the needle is to be thrown out of action it is raised until its neb
is above the path of the knitting cam and the loop has passed into the recess 1,
turning both latches away from the hook in so doing. When the needle is to be
thrown into action again the loop first raises the lower latch into the position
shown in Fig. 2 and then passes over both latches into the hook a.
course the loop passes over the latch b and between it and the latch e as the needle
rises, and on the return stroke the loop passes under the latch b. closing the hook a
..and acting in the usual manner.
At the next
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'
claim is :-
A needle for latch needle knitting machines, particularly applicable to machines
and for the purpose herein set forth, the said needle having two latches so arranged
that the upper latch and the hook can be worked in the usual way while if the
needle is raised until its neb is above the path of the knitting cam and the loop
below the second latch it can be thrown into action again without reference to the
relative position of the knitting cam or thread carrier, and without the loop passing
over the end of the needle or closing the latch as herein'shown and described.
