PROVISIONAL SPECIFICATION.
Improved Means for and Methods of Knitting, applicable to Straight
and Parallel Bar Latch Needle Knitting Machines.
FREDERICK WILLIAM PARE 20 Waterloo Road Nottingham Lace Manufacturer
do hereby declare the nature of this invention to be as follows:-
This invention relates to means and methods applicable to straight and, parallel
bar latch needle knitting machines, and has for its object the production of two or
more knitted courses or rows of loops for each traverse of the cam box or cam
boxes.
According to this invention each needle in work in each needle bed is so actuated
that it makes two or more loops for each traverse of the knitting cam, instead of
one loop only as in existing machines. For actuating the needle as above each
knitting cam box is provided with two or more inclines for raising the needlos, and
two or more inclines for depressing the needles, or the same result may be obtained
by using two or more distinct cams for each needle bed, each cam box being
provided with one incline for raising the needles, and one incline for depressing
the same.
By preference the cam boxes are without movable inclines, and the thread
carriers, one for each needle raising incline, traverse to and fro with the cam
boxes without changing their relative position with the inclines at the end of each
traverse.

COMPLETE SPECIFICATION.
Improved Means for and Methods of Knitting, applicable to Straight
and Parallel Bar Latch Needle Knitting Machines.
FREDERICK WILLIAM PARE 20 Waterloo Road Nottingham Lace 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 relates to improved means for and methods of actuating the
needles in straight and parallel bar latch needle knitting machines, the object of
the invention being the provision of means for enabling two or more knitted
courses or rows of loops to be produced for each traverse of the cam box or boxes
across the needle bed.
In carrying out this invention each needle in work is so actuated that it makes
two or more loops for each traverse of the cam box or boxes and this result may
be obtained by means of a single cam box, having two or more sets of inclines, or
by means of two or more cam boxes each having a single set of inclines, the cam
boxes in the latter arrangement being connected together so as to move as a
single box.

page_text: In the drawings which illustrate this invention.
Fig. 1. is an elevation of a cam plate with fixed incliuos for knitting two courses
at each traverse of the cam box.
Fig. 2. is an elevation of a cam plate with inclines for knitting two courses at
each traverse of the cain box, the end inclines being pivotted.
The cam plate a is fitted to slide vertically in, or on, the cam box for the
purpose of regulating the size of the loop produced, and any usual means may be
adopted for adjusting the cam plate and for holding it in its placed position.
The inclines shown in Fig. I comprise an upper piece band lower piece o which
are fixed to the plato a. Theso inclines are placed rolativoly to each other so as
to form a passage d for the heels of the needle jacks, the corners e are bevilled to
ensure the heels of the needle jaoks entering the groovo d, and the flats are made
of about equal lengths so that a certain number of needles are positively held in
their knocking over position. The corners g are also bevilled to allow of the
inclines passing over the heels of any jacks which may be out of work. With a
cam having inclines as here described the thread carriors are fixed relatively to the
inclines, and they may be attached to the cam plate a or any other similarly moving
part of the machine.
In the arrangement shown in Fig. 2 the cam box is supposed to be moving from
right to left. The heels of the needle jacks strike the lower piece above the
point, they then pass over the pivotted piece k, the first row of loops being
knocked over at land the second row at o. After passing this point the needles are
raised again by the incline m and are finally lowered to the knocking over level by
the incline n. On the return traverse of the cam box the pivotted piece p is raised
by the jacks to a position similar to the piece while the piece is lowered to a
position similar to the piece p. When the cam box is moving from left to right
the thread is taken by the needles at the rises r and s, and when moving from right
to left the thread is taken at the rises and a, and the thread carriers accordingly
change thoir relative positions with regard to the inclines.
When this invention is applied to straight bar latch needle knitting machines,
the thread supplied during tho traverse of the cam box in one direction to the first
formed row of loops is supplied during the return traverse of the cam box to the
last formed row of loops and there is consequently one or more long loops at each
selvage, the length and number of such loops depending upon the number of
courses knitted for each traverse of the cam box. These loops however are
seamed in when the edges of the fabric are joined together and therefore are not
objectionable. When howover the invention is applied to parallel bar latch needle
knitting machines producing circular fabrics the long loops formed as above
described would be objectionable but when the invention is applied to parallel bar
latch needle knitting machines producing ribbed work, the long loops at the
selvages would be seamed into the article as described with referenco to goods
made on the straight bar machine.
The angle of the inclines may be similar to the angle of incliues knitting a single
course for each traverse, they may be straight or curved and may be arranged to
produce more than two courses at each traverse of the cam box.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manuer the same is to be performed, I declare that what I
claim is:-
:-
The combination with, and the application to straight and parallel bar latch
needle knitting machines, of cam boxes having inclines arranged to produce two or
more knitted courses or rows of loop for each traverse of the cam box or boxes
substantially as herein set forth.
