PROVISIONAL SPECIFICATION.
Improvements in Drafting and Punching Jacquard Patterns, and in
Apparatus therefor.
I, ROBERT SCOTT, of 37, Birrell Road, Sherwood Rise, Nottingham, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the patterns required for the embroidery machine
described in my Specification No. 20253 of 1897.
In this machine there are four rows of jacquard needles for giving the up, the
down, the to and the fro motions respectively to the embroidery frame."
For each stitch therefore. not more than two holes have to be punched one for
either the up or down motion and the other for either the to or fro motion.
I employ a punching machine similar to the well known "piano" machine but
having four rows of punches in place of one. The punches of the two middle rows
stand up higher than the outer 'ones and on each side there are two rows of needles
at different levels the higher one when pushed inwards coming above and operating
the middle punches and the lower ones coming above and operating the outer
punches. The punches act on a band of paper to which a step by step motion is
given by the treadle of the machine.
The pattern is drawn on the ordinary ruled paper and in drafting a cross preferably
of transparent material and having on its arms numbers corresponding to numbers
on the punches is employed. The centre of the cross is put over the place of a
stitch on the pattern and the numbers on the vertical and horizontal arins opposite
the next stitch are read off and the corresponding needles pushed in.
Dated this 10th day of March 1898.
Improvements in Drafting and Punching Jacquard Patterns, and in
Apparatus therefor.
I, ROBERT SCOTT, of 37, Birrell Road, Sherwood Rise, Nottingham, 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:

For each stitch therefore not more than two holes have to be punched one for

given by the treadle of the machine.
The pattern is drawn on the ordinary ruled paper and in drafting a cross preferably
of transparent material and having on its arms numbers corresponding to numbers
on the punches is employed. The centre of the cross is put over the place of a
stitch on the pattern and the numbers on the vertical and horizontal arms opposite
the next stitch are read off and the corresponding needles pushed in.
Figure 1 is a side elevation, Figure 2 an end elevation and Figure 3 a plan of the
punching machine.
a and b are two treadle levers pivotted at a¹ and 6. The lever a is connected by
the rod a² to the lever 3 pivotted at a and connected at the other end by the
rod as to the lever c pivotted at c¹. The lever b is directly connected by the rod 6²
to the lever c and the latter is connected by the rod c² to the crosshead c³.
The crosshead c³ is connected by the rods .c to the punch box d. The result
of this arrangement is that when the treadle a is depressed the punch box d
is also depressed whilst the treadle 6 is raised. Depressing the treadle b
on the other hand raises both the treadle a and the punch box d, So far the
arrangement is old and well known. The punch d has four rows of punches d¹
and of needles d² instead of one as is usual. e is a band of paper supplied from
a reel e and drawn through the slot f¹ in the punch block f by the pair of feed
rolls h. The shaft of the lower feed roll carries a pinion h¹ gearing with an inter-
mediate pinion h² which also gears with a pinion j on the same shaft as a polygonal
pin wheel a ratchet wheel and a polygonal brake wheel m. A step by step
motion is given to these wheels by the pawl n pivotted to the radial arm n¹ gearing
with the ratchet wheel and operated by the rod 63 pivotted to the treadle lever b.
The edges of the paper e have in them lines of holes to receive the pins of the
wheel k. All motion of the latter wheel is prevented whilst punching is going on
by the spring brake arm m¹ (Figure 4) which rests on the polygonal brake
wheel m.
Figure 5 shows the method of drafting. The pattern represented by the line o o
is drawn on the ordinary ruled paper p and the positions o¹ 02 03 &c. of the stitches
are marked on it. Assuming that o' is the last stitch for which the paper e has been
punched the transparent and numbered cross q is put on the pattern paper p with
its centre over the point o¹ and with its arms parallel to the rulings.
The reader then indicates the position of the point o² to the boy working the
punching machine by calling out the Figures 9, 5 which are the figures on the cross on
the same horizontal and vertical lines as o². The boy then presses in needle 9 in the
top front row and needle 5 in the bottom front row and works the treadles.
Meanwhile the reader moves the cross q to bring. its centre over o² and calls the
position of 03 and so on. If an even number be called as is the case if the next
stitch is to be the left of or below the last the boy,presses in the back needles instead
of the front.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-

page_text: 2. Punching machines substantially as described and illustrated in the
drawings.
3. The cross q (whether transparent or not) substantially as described.
4. The means substantially as described for drafting and punching jacquard
patterns.
