PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Bordered Carpets and in
Looms for the same.
I, HENRY FAWCETT of Kidderminster, Carpet Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention has for its object improvements in the manufacture of bordered
carpets and in looms for the same.
The way in which bordered carpets are now usually woven in breadths under a
former patent granted to me No. 2088 in the year 1883 is to weave first the border
piece at one end of the breadth in an ordinary Jacquard carpet loom; then to dis-
engage and lift down the Jacquard cards-next to bring up other cards and arrange
these on the Jacquard cylinder for use in weaving the body portion of the pattern.
When this has been done a like change has again to be made before the loom can
weave the border at the other end of the length. These repeated changes involve so
much labor that the cost of weaving is greatly enhanced.
Now according to my present invention I provide a loom with two or more
Jacquards each with its own cards. Each Jacquard is tied up with the figure warps
of the fabric and when at work raises them in selected order under the control of the
cards with which it is provided. The loom is provided with mechanism for putting
these Jacquards into and out of work and only one of the Jacquards is in action at a
time.
In weaving bordered carpets with a loom so provided with two or more Jacquards
all that is required in making the change from border to pattern and vice versa is to
stop one Jacquard and start another and all the labor and loss of time involved in
changing the cards is avoided.
COMPLETE SPECIFICATION.
Improvements in the Manufacture of Bordered Carpets and in
Looms for the same.
I, HENRY FAWCETT of Kidderminster, Carpet 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 has for its object improvements in the manufacture of bordered
carpets and in looms for the same.
The way in which bordered carpets are now usually woven in breadths under a
former Patent granted to me No. 2088 in the year 1883, is to weave first the border
piece at one end of the breadth in an ordinary Jacquard carpet loom; then to dis-
engage and lift down the Jacquard cards, next to bring up other cards and arrange
these on the Jacquard cylinder for use in weaving the body portion of the pattern.
When this has been done a like change has again to be made before the loom can
weave the border at the other end of the length. These repeated changes involve so
much labour that the cost of weaving is greatly enhanced.
Now according to my present Invention I provide a loom with two or more
Jacquards each with its own cards. Each Jacquard is tied up with the figure warps
of the fabric and when at work raises them in selected order under the control of the
cards with which it is provided. The loom is provided with mechanism for putting
these Jacquards into and out of work and only one of the Jacquards is in action at a
time.

In weaving bordered carpets with a loom so provided with two or more Jacquards
all that is required in making the change from border to pattern and vice versa is to
stop one Jacquard and start another and all the labour and loss of time involved in
changing the cards is avoided.
Figure 1 of the drawings annexed shews a vertical elevation partly in section of
Jacquard mechanism constructed in the manner I prefer for carrying out my
Invention.
Figure 2 is a diagram view of one of the Jacquard cylinders and needles, the
cord threaded through its eye and the lifting board.
Figure 3 is a plan view of part of the lifting board shewing the form of the holes
made through it.
In these figures A. A are the Jacquard needles. B B are two Jacquard cylinders
each carrying its own cards one set for the border piece and one set for the body
portion of the pattern. One cylinder is as shewn capable of being made to act
against one end of the needles and the other against the opposite end. The axes at
the two ends of each cylinder can turn in bearings in two slide bars C which can be
slidden end wise in bearings to move the cylinder towards or away from the ends of
the needles.
The slide bars have, pins C¹ projecting from them which enter into slots in lever
arms D which can be rocked on axes D. Each axis has an arm D extending from
it and this at its end has a rod D³ descending from it which is drawn downwards by
the action of a spring or weight whenever the Jacquard cylinder is to be drawn
against the needles--or can be raised by the action of a cam when the cylinder is to
he moved away from the needles in the ordinary manner.
Whichever cylinder is for a time to be kept out of action is kept at its furthest
distance from the needles by the lever to which the slides which carry it are jointed
being upheld by a catch D which can be brought under and made to uphold an
arm D on the axis of the lever D.
In addition to providing two Jacquard cylinders B B one to work against each end
of the needles I also similarly provide two levelling up boards E E. Whenever either
one or other of these boards is to be brought into action its ends are allowed to drop
into and be held by the hooked ends of two swinging arms F-combinations of these
arms are coupled by links to arms G on the axis D₁ consequently the board swings
to and fro with the cylinder B which is at the opposite end of the needles and as the
cylinder goes away from one end of the needles it comes against the opposite end of
the needles and moves them back to a uniform central position. When it is required
not to be in action it is lifted up and out of the way by mechanism such as shown in
the drawing so as not to be between the needles and the Jacquard cylinder which is
then for the time in action.
The several holes in the lifting board H up through which the lifting cords I are
led are shaped in the manner shewn at Figure 3 with a slot extending from opposite
sides of the hole. When the cords I pass centrally through the hole and the board
is lifted in the ordinary manner the knots I' on the cords will pass freely through
the holes and the cords will not be raised-if however the needle A to which any
cord is threaded is pushed from its central position either towards one end or the
other the cord will be deflected and moved into either one or other of the narrow
slots which extend from opposite sides of the hole and then when the board is lifted
the cord is carried up with it the knot I' not being able to pass through the slot.
In place of the holes being formed in this manner they might be formed with a
slot at one side only of the hole in the ordinary way. In this case the set of cards
carried by one or other of the Jacquard cylinders would have to be punched on a
system the opposite of that used in the other set-that is-that if a hole would
have to be punched in a card carried by one cylinder to cause one or other of
the cords to be lifted then if it is desired to cause that cord to be lifted by the
action of a card carried by the cylinder at the opposite end there would be no
hole punched in the card where that card would be brought to bear against the
needle to which the cord is threaded.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. The manufacture of bordered carpets in looms provided with two Jacquard
cylinders one carrying cards suitable for controlling the making of the border the
other carrying cards suitable for controlling the making of the body and with either
Jacquard cylinder capable of being brought into action whenever desired.
2. A loom having two Jacquard cylinders either of which can at pleasure bo
brought into action when the other is held at rest each cylinder carrying its own
set of cards and when in action controlling the raising and lowering of the warp.
3. The construction of Jacquard mechanism for looms substantially as hereinbefore
described and illustrated in the drawing annexed.
