PROVISIONAL SPECIFICATION.
Improvements in Cross Border Jacquards.
I, FREDERICK LANCASHIRE, of Empress Avenue, Marple, in the County of
Chester, Manager, do hereby declare the nature of this invention to be as
follows:-
This invention is designed to provide suitable mechanism for actuating the
cylinder of cross border jacquards, in which two cylinders and a duplicate set
of needles are employed, one cylinder being stationary whilst the other is
working.
The cylinders are each carried by an ordinary swinging frame, and these frames
are caused to oscillate by means of a connecting rod worked from an eccentric
or cam on the driving shaft of the loom.
Upon the top end of the connecting rod I fit a crosshead of T or other suitable
shape, which can be brought into contact with one of two bowls, pins or their
equivalent by moving the upper end of the connecting rod or the cross head
thereon horizontally to one side or the other as may be required.
The upper end of the connecting rod or the cross head thereon is connected
by a fork or otherwise to a sliding bar or rod by which it can be moved to and fro
horizontally while the loom is running.
The bowls pins or their equivalent with which the cross head of the connecting
rod engages are carried by levers which project towards each other, and by an
oscillating shaft and levers or arms are connected to the framing of an ordinary
swinging cylinder motion.
By moving the upper end of the connecting rod, it may be brought to engage
with either of these bowls.
The slide connected to the cross head is moved to and fro as required by a
chain passing over a pulley or by a lever or other device.

Improvements in Cross Border Jacquards.
I, FREDERICK LANCASHIRE, of Empress Avenue, Marple, in the County of
Chester, Manager, 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 Jacquard mechanism for cross border weaving in

page_text: which two cylinders and a duplicate set of needles are employed, one cylinder
being stationary, whilst the other is in operation and is designed to provide
suitable mechanism for actuating the cylinders and throwing the mechanism into
and out of gear with the cylinder levers.
It consists essentially in constructing the connecting rod with a head of T or
other suitable shape to engage alternately the pins or bowls of bell crank levers
operating the cylinders and a slide connected thereto whereby the head of the
connecting rod can be moved horizontally to engage with the lever at one side or
the other
It will be fully described with reference to the accompanying drawings.

The cylinder A for the centre cards and the cylinder A' for the border cards
are each carried by an ordinary swinging frame B B. The frames B B¹ are
operated by the bell crank levers C C¹ pivoted to the frame and oscillated as re-
quired by a connecting rod D) reciprocated continuously by an eccentric or can E
on the loom driving shaft F.
The bell crank levers C C¹ at their outer or free ends are provided respectively
with pins or bowls c c¹ with which the head of the reciprocating connecting rod
D engages.
The upper end of the connecting rod D is fitted with a head or cross head H
of or other convenient form provided with a notches h h at each side. By
moving the head H to one side or the other one of the notches can be brought
into engagement with the bowls c c on the ends of the levers C C¹ between which
the head H is placed.
The head H of the connecting rod D is connected to a sliding bar G by which
it can be moved to and fro horizontally while the loom is running. The sliding
piece or bar G rests upon pins g projecting from the frame L upon which it slides
to and fro and is actuated by a crank pin k in a disc or wheel K working in a
slot y' in the bar. The pink may be attached to a wheel or pulley K serving
as a band or chain wheel rotated by a band or chain or it may be attached
a disc K' with a band or chain wheel K in a convenient
position on the same shaft by rotating the chain wheel the head of the
connecting rod D) is thrown into engagement with the levers that operate the
border cylinder A¹ or the centre cylinder A as required.
to
In the arrangement shown in Figs. 1 to 6 the cylinders A and A¹ are thrown
into and out of gear by the chain k¹ rotated by the hand of the operative, but
the changing from one cylinder to the other may be performed automatically
by the loom after the weaving of any given number of picks, as shown in Figs. 7
to 9.
In these Figs. 7 to 9 the crank pin k which operates the sliding bar G to move
the crosshead H is affixed to a disc K¹ on the same shaft as the band wheel K",
a continuously running band M' passes over the wheel K" which is prevented
rotating except as required by a pawl or catch n engaging with the wheel N on
the same shaft or gearing therewith. The pawl n is lifted and the wheel N
allowed to rotate by the bowl o on the end of the lever O. The lever O, is pivoted to
the frame L and is slowly rotated about its pivot 7 by a pawl p engaging with
the ratchet wheel of on the boss of the lever. The pawl p is pivoted on an

page_text: oscillating lever P which is connected by a cord p¹ with a moving part of the
jacquard and is caused to move at each shot of the loom. The lever O is thus
caused to slowly rotate upon its pivot until the bowl o engages the depending
end of the pawl' and releases the wheel N. The movement of the band wheel Ki
rotates the disc K¹ and pink moving the slide G and cross head H to operate the
border cylinder A¹. The slide G is moved back again with the cross head H
at the next half revolution of the disc K¹.
Instead of the lever O a disc with one, two three or more pins or teeth may be
employed to raise the pawl n to release the wheel N, thus the cross pattern or
border may be woven in at any desired intervals.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:.
:―
1. A Jacquard mechanism for cross border weaving constructed with a head to
the reciprocating connecting rod capable of engaging with a lever at either
side and a sliding bar or rod to which it is connected operated by an eccentric
crank pin or similar device whereby by rotating a wheel or shaft the reciprocating
connecting rod is thrown into engagement with the centre cylinder or the border
cylinder, substantially as described.
2. In mechanism for cross border weaving the combination with the cylinders A
and A and the levers CC by which they are operated of the cross head H on
the reciprocating connecting rod D capable of engaging with either lever, the
slide G and the crank pink and disc K or K by which the slide is moved backwards
or forwards, substantially as described.
3. A Jacquard mechanism for cross border weaving having the several parts
constructed and arranged in combination, substantially as described and shown
with reference to either of the figs. of the drawings.
