page_text: We, GEORGE HENRY NUSSEY of the firm of Hargreave and Nusseys, Boar Lane,
Leeds Woollen Manufacturer, and THOMAS HASKARD of Dixons Lane, Wortley, near
Leeds, Lace Maker, both in the County of York, do hereby declare the nature of this
invention, to be as follows:-
The object of our invention is to construct a warp knitting machine capable of
knitting two pieces of plush or pile fabric simultaneously.
In our arrangement the two backs or foundations are formed at one time and the
plush or pile between them, which is afterwards cut, thereby separating the two
pieces.
The framework of the machine is similar to that usually employed for knitting
machines, and for the purpose of forming the two pieces together we provide two sets
of bars of similar construction, and to them is imparted simultaneously a vertical
reciprocating movement. Each of these bars is provided with any required number
of needles. When the needles have been carried down by the bars to the full extent of
the stroke guides are employed for conducting or wrapping the threads round them,
these needles are then caused to rise with the bars and come in contact with "tricks
which knock the previously formed loops off the needles, forming thereby or at the
same time another set of loops.
"
The number of the aforesaid guide bars employed in forming the foundation and pile
depends upon the quality of work to be done.
The pile or plush is formed by the central bars wrapping the threads first on one set
of needles and then upon the other, and the "tricks" throw off these threads at the
same time as those that are used for forming the foundations. Each previously formed
loop is prevented from being dragged down along with the needle in its downward
stroke by means of a pin or "point" which operates as follows
When the loop has been formed on the needle such needle moves downwards and

page_text: the pin or "point" holds this loop and prevents it going with it; by this movement
the loop passes up the stem of the needle and leaves the bottom end thereof free for
again wrapping on the thread by the guide to form another loop.
A horizontal movement is imparted to the guide bars in order to bring the guides
into their required positions to suit the different changes of needles.
In the above arrangement of machine "bird or "latch" needles may be
employed.

We GEORGE HENRY NUSSEY of the firm of Hargreave and Nusseys Boar Lane
Leeds Woollen Manufacturer, and THOMAS HASKARD of Dixon Lane Wortley near
Leeds, Lace Maker both in the County of York, 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:-
The object of our invention is to construct a Warp Knitting Machine capable of
knitting two pieces of plush or pile fabric simultaneously. In our arrangement of
machine the two backs or foundation of the material and the plush, or pile between
them are formed simultaneously therewith; the plush or pile being afterwards cut or
divided, thereby separating the two pieces. In the accompanying drawings Fig. 1 is
a longitudinal elevation shewing left side. Fig. 2 longitudinal elevation of right
side. Fig. 3 an end elevation and Fig. 4 an enlarged view in cross section through A B
Fig. 2 of machine.
The framework A of the machine is of ordinary construction and is similar to that
usually employed for knitting machines, and for the purpose of forming the two pieces or
backs B and C together as shewn at Fig. 4 we provide two sets of needle bars D. D,
of similar construction and to them is imparted simultaneously a vertical reciprocating
movement in opposite directions by means of the revolving cams E, on the horizontal
shafts FF through the runners G and brackets H attached to the needle bars D D as
shewn at Figs. 2 and 4, and in order to steady the movement of the needle bars DD,
we employ the sliding pillars J which work in fixed brackets K, such brackets being
attached to the framework A by means of screws or bolts. Each of these needle
bars D D is provided with any required number of needles L of suitable pitch. When
the needles L have been carried downwards by the needle bars D D to the full extent
of the stroke, guides M attached to the guide bars N are employed for conducting or
wrapping the threads round such needles L these needles L are then carried upwards
alternately by needle bars D D and come in contact with the fixed "tricks" O'which
knock the previously formed loops off the needles L making at the same time another
set of loops. The number of the aforesaid guide bars N employed in forming the
foundation and pile depend upon the quality of work to be done. The pile or plush R
shewn at Fig. 4 is formed by the central guide bars N wrapping the threads first on
tricks" throw off
one set of needles L and then upon the other, and the fixed
these threads at the same time as those that are used for forming the foundation or
backs B and C. In order to impart the required horizontal reciprocating movement
to the guide bars N for the purpose of wrapping the threads first on one set of
needles L and then upon the other, we employ the rotating cams R' on the shaft S,
these impart the reciprocating movement to the guide bars N through runners T,
connecting rods U and V and, levers W, such levers W being mounted on the rocking
shaft X carried in suitable bearings Von the framework A. Each previously formed
loop is prevented from being dragged down by its needle in the downward stroke by
means of pins or "points" 1 and 2 which operate as follows:-
These pins or points 1 are attached to a sliding or moving piece 3 to which is
imparted a horizontal reciprocating movement through connecting rods 4, levers 5,

page_text: runners 6, and cams 7 mounted on the horizontal shaft F, a somewhat similar move-
ment being imparted to the pins or points 2 through arms 8 mounted on rocking
shaft 9, levers 10, runners 11 and cams 12 mounted on the horizontal shaft F. The
pins or points 1 and 2 move away, when the needles L are returning from taking up
the threads from the guides M. When the loop has been formed on the needles Land
the pins or points having again entered between the threads such needles move
downwards and the pins or points hold these loops and prevent them going down with
the needles L; by this movement the loops are pushed up the stem of the needles L
and leave the bottom end thereof free for again wrapping on the threads by the
guides M to form other loops. As the material is being formed it passes up between
the tricks carriers 12' and when it is desired to separate the two pieces as they are
formed on the machine, a knife or cutter 13 operated by ordinary means may be
employed. The material after being cut is drawn away by porcupine rollers 14,
which are operated by worm gearing 15 from shafts F F, and thence between suitable
conducting rollers 16 into a box or receiver 17, or conducted away by other means
when required.
That part of the framework marked A' is made adjustable so that its distance may
be regulated or adjusted with regard to corresponding portions of the other side of the
machine such adjustable movement being effected through screws 18, nuts 19,
gearing 20, shaft 21 and hand wheel 22. A spring dropper "jacquard" as used for
ordinary lace making may be employed to actuate the guide bars N through shaft 23
and gearing 24, or other convenient means may when required be employed.
Ordinary driving pulleys 25 and gearing 26 are employed to transmit motion to the
various cams and other moving parts of the machine.
In the above arrangement of machine "bird
or "latch "
needles may be
employed. The ordinary beams and beam racks for supplying the threads are employed
in the above described machine.
"
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 :-
1st. The general arrangement and aplication of double sets of needles L, and pins or
points 1 and 2 in combination with the fixed tricks O and guides M operating and
actuated substantially as herein setforth for knitting two pieces of plush simultaneously.
2nd. The general arrangement construction and combination of the various parts
forming the machine for knitting two pieces of plush or pile fabrics simultaneously
substantially as herein set forth.
