PROVISIONAL SPECIFICATION.
Improved Machinery and Apparatus applicable to Jacquard Card
Punching Machines.
We PETER PEARSON, Curtain Corrector, and ALBERT GODWARD, Draughtsman,
both of 28 Willoughby Street, Beeston, Nottinghamshire, do hereby declare the nature
of this invention to be as follows:-
Our improved apparatus dispenses with the necessity of reading the pattern
previous to punching the jacquard cards, this we effect by the following means.
We employ a wood or metal frame capable of adjustment as to its length and
width.
The pattern being designed in the ordinary way is transferred by tracing or other
method to a sheet of india rubber placed upon the wood or metal frame before named,
which is then expanded if the pattern requires enlarging.
If the pattern has to be reduced it is transferred to an expanded sheet of india
rubber on the frame which is then contracted to the size required.
From the india rubber sheet the pattern is transferred onto a sheet of perforated
block tin, zinc, copper, or other suitable metal, and draughted, by which process the
holes in the sheet of metal are filled where required by a moist compound consisting
of flake white ground up with gum, or other suitable cement, which being allowed to
dry sets hard. The perforated sheet of metal with the draughted pattern upon it, is
then placed upon a specially constructed machine consisting of the following
parts:
Two side standards connected by tie bars, and carrying bearings for a cam shaft,
and two rollers which support the perforated sheet of metal, or round which two
endless perforated metal bands are placed, upon which the perforated sheet of metal
may be adjusted, both rollers are provided with projecting studs near each end, these
studs either engage with the outer rows of holes in the perforated sheet of metal, or
with the perforated metal bands carrying. the sheets of metal, near one end of the
front roller a toothed ratchet wheel is secured, operated by a driver hinged to a
lever, the front end of which is slotted, and clips the roller on which it slides or.
rocks, the back end of the lever carries a truck operated by a cam, or a stud on the
cam shaft, each revolution of which produces a partial revolution of the frout roller
and carries forward the perforated sheet of metal the distance required. The
axle of the driver is capable of adjustment in a slot of its carrying lever, to
regulate the throw of the driver to the exact gange of the perforated sheet of
metal.
In front of the machine are plates or sleys supporting one or more rows of
horizontal needles the front end of each needle is connected by a string, or wire, to
the repeating strings which are hooked onto the needle in the selecting box of an
ordinary jacquard card punching press placed in front of the machine. The back
ends of the horizontal needles are hooked, so as to engage with the blade of a grid,
carried by rods operated by cams on the cam shaft, the grid taking the needles
back when not lifted by the following means. Between the standards over the cam
shaft is a cylinder, having its stop slotted from end to end, this cylinder is caused
to rise vertically by cams, when at its highest position the top lies close under the
perforated sheet of metal on which the pattern has been drafted, one row of per-
forations lying exactly over the slot in the cylinder.
Above the perforated sheet are sleys carrying a second series of horizontal needles,
each connected to a vertical needle, the lower end of each vertical needle passes.
through one of the perforations in the sheet of metal into the slot of the cylinder
beneath it as the cylinder rises. The lower ends of the vertical needles which are.

page_text: over the perforations closed by the hardened draughting compound are raised and
lift the back hooked ends of the second series of horizontal needles clear above a
horizontal selecting bar carried by rods operated by cams.
The lower ends of the vertical needles which pass through the perforations in the
sheet of metal have their horizontal needles moved backward by the selecting bar at
. each revolution of the cam shaft..
Each needle so moved being connected by a string to the back hooked end of one
of the horizontal needles first named at the front of the machine raises such needle
clear of the grid and remains at rest while the grid' moves backward.

COMPLETE SPECIFICATION.
Improved Machinery and Apparatus applicable to Jacquard Card
Punching Machines.
We PETER PEARSON Curtain Corrector and ALBERT GODWARD Draughtsman both
of 28 Willoughby Street, Beeston, Nottinghamshire 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 carrying out our improvements we propose to confine ourselves to the apparatus
described in the first part of our provisional specification and abandon the specially
constructed machine described in the second part.
Figure 1 shows a pattern designed in the ordinary way.
Figure 2 shows the same pattern transferred to an expanded sheet of india rubber
in a frame.
Figure 3 shows the same frame with the transferred pattern slightly extended in
length and contracted in width.
Figure 4 shows the extended and contracted pattern transferred onto and
draughted upon a perforated sheet of metal.
Figure 5 is an enlarged view showing the perforations in one square inch of the
sheet of metal, and
Figures 6 and 7 show respectively an enlarged plan and edge view of one of the
clamping sockets for adjusting the sides of the frame.
Our improved apparatus dispenses with the necessity of reading the pattern after
it is draughted previous to punching the jacquard cards, this we effect by the
following means. We employ a wood or metal frame the sides A of which are placed
at right angles to each other in metal clamping sockets B each provided with two
set screws B¹ "see Figures 2, 6, and 7," which secures the sides of the frame in
position after adjustment to or from each other.
Within the frame we place a sheet of india rubber C near the edges of which
small holes are punched at about one inch apart, in each hole a small metal eyelet is
secured, each eyelet being provided with a loop of cord (, through the loops the
sides of the frame are passed, and hold the sheet of india rubber in a central
position. The pattern D shown at Figure 1 designed in the ordinary way is placed
beneath the sheet of india rubber in the frame, the rubber is sufficiently transparent
to show the design beneath it. The design is traced in outline on the rubber with a
medium of flake white or other colour ground up with gum arabic or other suitable
cement water and a small portion of glycerine sufficient to keep the medium moist:
while the frame is expanded, "if the pattern requires enlarging" and, secured by the
set screws B. If the pattern has to be reduced it is traced upon an expanded sheet
of india,rubber in the frame which is then contracted to the size required. The frame
and india rubber sheet is then turned face downwards on to a sheet of perforated

page_text: block-tin, zinc, copper or other suitable metal E, the pattern D being transferred to
the sheet of metal either by pressure or by rubbing the back of the india rubber
sheet.
The pattern D is then draughted on the sheet of perforated metal É as shown at
Figure 4. the draughtsman employing for that purpose a moist compound, consisting
of flake white ground up with gum arabic or other suitable cement and water, which
being allowed to dry sets hard filling up the perforations where required.
The perforated metal plates E are each divided into squares or oblongs to assist
the draughtsman. The perforations being made in parallel lines at an equal distance
from each other, the perforations may be either "ound as shown at Figure 5 or they
may be square, the lines E' which divide the sheet into squares or oblongs may be
etched or engraved or the lines may be ruled on the plate with a dark coloured
varnish.
The number of perforations in each square inch is 168 when punched to a guage
of 12 long and 14 wide as shown at Figure 5. But we do not confine ourselves to
that guage, as the perforations may be made to any suitable guage with a greater or
less number of perforations in length and width according to the fineness or coarseness
of the fabric to be produced.
When the draughting compound is quite dry and hard the perforated plate is
ready to be placed under the selecting needles of a reading machine the compound
filling the perforations select the needles, and the perforations not filled allow them
to pass through.
We are thus enabled to dispense with the necessity of reading the pattern after it
is draughted.
The cards being punched direct from the pattern draughted on the perforated
sheet of metal thereby avoiding any mistakes liable to be made by a reader.
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 :-
1. The construction and employment of a frame the sides of which are capable of
adjustment to or from each other, the sides of the frame lying in loops of cords
attached to eyelets secured in a sheet of india rubber, upon which a pattern may
be traced and then enlarged or contracted substantially as described for the purpose
specified.
2. The use of a mixture of flake white or other colour gum arabic or other suitable
cement water and glycerine as a moist medium for tracing a pattern on a sheet of
india rubber, and after enlarging or contracting the pattern transferring it on to a
sheet of perforated metal substantially as described.
3. The employment of a perforated sheet of metal upon which a pattern may be
transferred from a sheet of india rubber, and draughted on the perforated sheet of
metal substantially as described.
4. The employment of a draughting medium made of flake white or other colour,
gum arabic, or other suitable cement, and water, with which the draughtsman fills the
perforations in a sheet of metal required to form the pattern, and which when dry
sets hard and prevents the passage through the perforations of the selecting needles
of a reading machine substantially as described for the purpose specified.
