Improvements in Cross Border Weaving Apparatus.
We, OGILVIE BLAIR GRAHAM, the younger, Managing Director, JOHN
WALLS, Foreman Damask Tenter, and HUGH MCKIBBIN, Foreman Mechanic,
all to the York Street Flax Spinning Company Limited, Belfast, in the County
of Antrim, Ireland, do hereby declare the nature of this invention to be as
follows:-
This invention is designed to provide Jacquard apparatus for cross border
damask weaving in which there will be obviated the necessity of removing the
cards for the different patterns to and from the cylinder which is the case in many
of the machines now in use, and in which the cards for the centre and for the
border patterns can readily be changed into and out of working position at will
by the operation of a lever and without the weaver leaving his place at the
loom.
We e construct the apparatus with one cylinder for each set of cards and we fit
all the card irons onto two horizontal bars capable of being traversed or caused to
travel to and fro on slides. On one of these bars is placed two oscillating levers
to carry each cylinder of the Jacquard machine. These oscillating levers are
actuated backwards and forwards by two side levers connected thereto and to the
rocking shaft of the Jacquard machine. At one end these levers are provided with
a vertical slot which allows them to engage with a pin affixed to each of the
oscillating levers, and by which means they are connected thereto.
A lever or cord is attached to these side levers by which they may be lifted off
the pins and disconnected from the oscillating levers and so allow the cylinder and
oscillating levers to fall back and remain against or in contact with the roller irons
which are attached to the card frame.
Another lever or cord also attached to the horizontal sliding bars or other
suitable place by which one set of cards can be drawn to the end of the loom on the
slides or wheels provided and the other set into working position in front of the
Jacquard machine.
The side levers are then released and in descending engage with the pins of the
oscillating levers and bring them into working position when the loom is again
ready for work. ·
By the use of a cylinder for each set of cards the cards and cylinder are never
separated from each other while in use in the loom as the cylinder is not attached
to the Jacquard machine as formerly but is connected to and hinged on the
horizontal bars carrying the card frame and travels with it.
These changes are accomplished with great economy of time as against the old
method and without the weaver having to leave his place in front of the loom.

We, OGILVIE BLAIR GRAHAM, the younger, Managing Director, JOHN
WALLS, Foreman Damask Tenter, and HUGH MCKIBBIN, Foreman Mechanic,
all to the York Street Flax Spinning Company Limited, Belfast, in the County of
Antrim, Ireland, 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 is designed to provide Jacquard apparatus for cross border
damask weaving or like work by which there will be obviated the necessity for
removing the cards for the different patterns to and from the cylinder, which is the
case in many of the machines now in use, and in which the cards for the centre and
for the border patterns can readily be changed into and out of working position
at will without the weaver leaving his place at the loom.
It consists essentially in providing the Jacquard apparatus with a movable
frame or carriage to support two or more cylinders and the cards necessary for the
different parts of the pattern to be woven each cylinder being carried on two
oscillating levers swinging on the movable frame or a carriage. When brought
into position the acting cylinder and its accompanying cards are moved backwards
and forwards into contact with the needles of the jacquard which they control by
two side connecting rods which swing upou the ordinary side levers fixed to the
rocking shaft of the Jacquard machine.
This will be fully described by reference to the accompanying drawings in which
as an example a Jacquard apparatus with two cylinders is shown.
Fig. 1. End elevation.
Fig. 2. Front elevation.
Fig. 3. Plan.
Each set of cards is provided with a separate cylinder A which is carried by a
pair of oscillating levers B swinging upon a frame formed of the "card irons" C
the roller carriers D the longitudinal shaft E upon which the oscillating levers
swing and a longitudinal bar F, this frame is capable of being traversed to and fro
horizontally to bring either of the sets of cards and cylinders A into position for
acting upon the needles of the Jacquard apparatus.
The cylinder A in action is moved backwards and forwards by two connecting
rods G which swing upon and are moved by the ordinary side levers H fixed to the
rocking shaft of the Jacquard machine. The free end of these connecting rods G
is formed with an open ended slot, one side of which projects and forms a sort of
hook which drops over and engages with a pin 6 fixed to the oscillating levers B
thus connecting these levers B to the rocking shaft h of the Jacquard machine and
receiving motion therefrom.
The connecting rods G are joined together by a bar g to which is attached a
cord or chain K by which they may be lifted off the pins b and the oscillating
levers B be so disconnected and allowed to fall back and remain against the roller
irons D which form part of the traversable frame for cards and cylinders.
A lever or cord M is attached to the longitudinal shaft E or other convenient
part of the frame by which the frame can be moved to right or left to bring one
of the cylinders and its cards into working position in front of the needles of the
Jacquard machine.
Each time it is desired to change the acting cylinder and cards the connecting
rods G are lifted and the oscillating levers B released allowing the cylinder to
fall back out of action the frame is then drawn endwise by the cord M until the
other cylinder and set of cards are brought opposite the jacquard and the connecting
rods G again lowered, in descending the projecting or hook shaped ends of these

page_text: connecting rods engage with the pins 6 on the oscillating levers B and so bring
the other cylinder A into working position and then the loom is ready t
started.
These changes are accomplished with great economy of time and without the
weaver having to leave his place in front of the loom.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is.
1. Apparatus for weaving cross border damask or like work constructed with a
horizontally sliding frame or carriage carrying two or more card cylinders and
cards and traversable endwise on rails oscillating levers upon which the cylinders
are mounted and detachable reciprocating connecting rods to joint the rocking
levers of the jacquard to the cylinders capable of being either attached to or
detached therefrom substantially as described.
2. The combination with a jacquard of two or more card cylinders and sets of cards
carried by a horizontally sliding frame, each cylinder provided with a pair of
oscillating arms pivoted on a longitudinal bar and provided with projecting studs
or pins, engaging when in position with reciprocating connecting rods attached
to rocking levers of the jacquard and receiving motion therefrom substantially as
described.
3. Cross border or like weaving apparatus having the several parts constructed
and arranged in combination substantially as described and shown.
