Improvements_connected with Apparatus for Operating the Rising
and Falling Shuttle-boxes of Looms for Weaving.
We JAMES COWBURN of Albert Mill, Silk Street, Eccles in the County of Lancaster,
Manager and CHRISTOPHER PECK of the same place, Manufacturer do hereby declare
the nature of this invention to be as follows:-
Our invention relates to looms for weaving and consists in improvements upon
certain arrangements which are described in the specification filed in respect of an
application by the above named James Cowburn and Christopher Peck for a patent
No. 6209 dated April 26th 1888.

The first part of our invention relates to apparatus for turning one or other or both
of the discs by which the crank-pin is caused to raise or lower the shuttle-boxes when
such shuttle-boxes have to be raised or lowered and for enabling the loom to be turned
backward and at the same time maintain the pattern chain and shuttle boxes in correct
position relatively to the "pattern" of the "piece or "cloth" being woven.
upon the axle of each of the discs we mount a pinion gearing into or engaging with
which is at times a toothed rack. Each of the toothed racks is jointed to a lever or
arm the two arms being formed upon a boss mounted so as to be capable of being
oscillated upon a stud or pivot. Jointed to one of the arms before mentioned is one
end of a connecting rod the other end of which embraces a crank pin mounted upon
the "tappet shaft or upon any other suitable shaft. A rib or flange formed upon or
secured to each of the toothed racks above mentioned is embraced by a jaw formed on
or secured to one end of a dart or needle. One end of each of the darts or needles
passes through and is capable of being slidden in a hole formed in a bracket
secured to one of the end framings of the loom. Each of the needles or darts is
jointed, near one end to one end of a bell-crank-lever capable of being vibrated

of the bell-crank-levers is provided with a tooth which at times passes into one of
two notches or recesses formed in the circumference of the disc in conjunction with
which the said bell-crank-lever is employed. Carried by a framing secured to one
end framing of the loom is a shaft or stud mounted upon which is a frame in which
and capable of being turned therein is the axle of a barrel around which passes a
pattern-chain or card-chain. We impart an intermittent motion to the said barrel
by means of a "noggin wheel" and star wheel such "noggin wheel" receiving
rotary motion from any convenient and suitable shaft of the loom. The frame in
which the said barrel is mounted we cause to oscillate by means of a cam so that

said darts or needles is moved longitudinally the toothed rack used in conjunction
with the said needle is caused to gear into or engage with the pinion upon the axle
of the disc used in conjunction with such needle and the said movement of the
needle will by means of the bell-crank-lever connected thereto remove the tooth
from the notch or recess in the edge of the said disc and the longitudinal movement
of the rack will cause the said disc to perform half a revolution. The turning of
the disc will raise or lower the shuttle boxes. Upon the pattern chain or card-chain
receding from the dart or needle a spring acting upon the said dart or needle will
withdraw the toothed rack out of gear with the pinion before mentioned and simul-
taneously allow the tooth to pass into one of the recesses or notches in the circum-
ference of the disc so that such disc will be prevented from being rotated. When
the pattern-chain or card-chain is caused to act upon the other dart or needle so
as to cause the disc in conjunction with which such dart or needle is used, to be

backward for any purpose the pattern-chain or card-chain and one or other or both
of the discs will also be turned backward and thus the pattern-chain or card-chain
and shuttle boxes will be maintained in proper position relatively to the pattern of
the "piece" or "cloth" being woven in the loom.

A further part of our invention relates to arrangements of apparatus for operating
the pattern-chain or card-chain used for causing or controlling the raising and lowering
of the shuttle boxes and this part of our invention is particularly applicable for use in
weaving patterns in which one portion of the pattern occurs at intervals and another
portion is repeated several or a considerable number of times in succession. In
carrying this part of our invention into effect we employ for causing or controlling
the raising or lowering of the shuttle boxes a pattern-chain which may be moved in
one direction or the other or alternately in both directions or remain stationary as
may be necessary or desirable for producing the pattern required to be produced. In
order to perform this part of our invention we employ a lag barrel around which
is passed a governing chain formed of suitable lags or plates. The said "lag barrel
is mounted upon a shaft capable of being rotated in bearings secured to one of the
end framings of the loom. Fast upon the said shaft is a toothed wheel. The pattern-
chain or card-chain before mentioned at times acts upon a dart or needle capable of being
slidden in guides. The said dart or needle is moved longitudinally in one direction
by the pattern-chain or card-chain and in the other direction by means of a spring.
The dart or needle above mentioned is connected in any suitable manner to a toothed
rack to which rack we impart a to and fro longitudinal motion by means of the lever
or arms previously referred to and employed for moving to and fro longitudinally
the racks which act upon the discs by which the shuttle boxes are raised and
lowered. When the dart or needle is acted upon by the pattern-chain or card-
chain the rack above mentioned will be caused to engage with the wheel upon the
shaft. before mentioned and thereby cause the lag barrel to be at times turned. To
move the pattern-chain or card-chain we employ a short shaft which receives rotary
motion from the crank-shaft or any other convenient shaft of the loom. Upon the
short shaft above mentioned we mount a sliding collar which while free to be moved
longitudinally thereon is caused to rotate by means of a key or feather and groove or
slot. Formed with or secured to the said collar are two bevel wheels one of which
is at times caused to gear with a bevel wheel which by means of a shaft and bevel
wheels at times transmits rotary motion to the barrel around which the pattern-chain
or card-chain passes.
Carried by and free to be turned upon a stud secured to one of the end-framings of
the loom is a lever one end of which by means of a fork and groove enables the
sliding collar to be slidden longitudinally. The end of the lever above named when
acted upon by suitable projections formed upon the governing lag-chain will cause
the sliding collar to he slidden so as to cause one or other of the bevel wheels to
cause the pattern-chain or card-chain to be moved in one direction or the other
and when certain others of the projections upon the governing Jag-cbain act upon
the lever above referred to, the bevel wheels will be placed in such position that
no rotary motion will be transmitted to the pattern-chain or card-chain.

Improvements connected with Apparatus for Operating the Rising
and Falling Shuttle-boxes of Looms for Weaving.
We JAMES COWBURN of Albert Mill, Silk Street, Eccles in the county of
Lancaster, Manager and CHRISTOPHER PECK of the same place, Manufacturer do
hereby declare the nature of this invention and in what inanner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
Our invention relates to looms for weaving and consists in improvements upon
certain arrangements which are described in the specification filed in respect of an
application by the abovenamed James Cowburn and Christopher Peck, for a patent
No. 6209, dated April 26th 1888.
The first part of our invention relates to apparatus for turning one or other or
both of the discs by which the crank-pin is caused to raise or lower the shuttle-
boxes, when such shuttle-boxes have to be raised or lowered, and for enabling the
loom to be "turned backward" and at the same time maintain the pattern-chain and
shuttle-boxes in correct position relatively to the " pattern "of the "piece" or
"cloth" being woven. Fast upon the axle of each of the discs we mount a pinion
gearing into or engaging with which is, at times, a toothed rack. Each of the toothed
racks is jointed to a lever or arm, the two arms being formed upon a boss mounted so
as to be capable of being oscillated upon a stud or pivot. Jointed to one of the arms
before mentioned is one end of a connecting rod the other end of which embraces a
crank-pin mounted upon the "tappet-shaft" or upon any other suitable shaft. One
end of each of the darts or needles passes through and is capable of being slidden
in a hole formed in a bracket secured to one of the end-framings of the loom.
Each of the needles or darts may be jointed near one end, to one end of a
bell-crank-lever capable of being vibrated upon a bar supported by one of the
end-framings of the loom. One end of each of the bell-crank-levers is provided with
a tooth which, at times, passes into one of two notches or recesses formed in the
circumference of the disc in conjunction with which the said bell-crank-lever is
employed. Carried by a framing secured to one end-framing of the loom is a
shaft or stud mounted upon which is a frame in which and capable of being turned
therein is the axle of a barrel around which passes a pattern-card-chain. We impart
an intermittent motion to the said barrel by means of a noggin wheel" such
noggin wheel" receiving rotary motion from any convenient and suitable shaft of
the loom. The frame in which the said barrel is mounted we cause to oscillate by
means of a cam so that the patteru-chain will, at times, be caused to act upon one
or other of the darts or needles so as to move such dart or needle longitudinally.
When either of the said darts or needles is moved longitudinally, the toothed rack
used in conjunction with the said needle is caused to gear into or engage with the
pinion upon the axle of the disc used in conjunction with such needle and the said
movement of the needle will by means of the bell-crank-lever connected thereto
remove the tooth from the notch or recess in the edge of the said disc, and the
longitudinal movement of the rack will cause the said disc to perform half a revolu-
tion. The turning of the disc will raise or lower the shuttle boxes. Upon the
pattern-card-chain receding from the dart or needle a spring acting upon the said
dart or needle will withdraw the toothed rack out of gear with the pinion before
mentioned and simultaneously allow the tooth to pass into one of the recesses or
notches in the circumference of the disc so that such disc will be prevented from
being rotated. When the pattern-card-chain is caused to act upon the other dart
or needle so as to cause the disc in conjunction with which such dart or needle is
used, to be turned, the shuttle-boxes will be raised or lowered. When the loom
is turned backward for any purpose the pattern-card-chain and one or other or both of
"
"

page_text: the discs will also be turned backward and thus the pattern-card-chain and shuttle-
boxes will be maintained in proper position relatively to the pattern of the "piece" or
"cloth" being woven in the loom.
This part of our invention is shown in the accompanying drawings in which Fig. 1
is a side elevation of so much of a loom as is requisite to illustrate this part of our
invention. Fig. 2 is a section of a portion of that which is shown in Fig. 1. Fig. 3
is an end elevation, Fig. 4 a side elevation and Fig. 5 a plan showing a portion
of that which is shown in Fig. 1. Figs. 3. 4 and 5 are upon a larger scale than Fig. 1.
The same letters of reference are applied to corresponding parts in all the figures.
Secured to one of the end framings of the loom that is to the end framing a¹ is a
frame a to which are secured brackets b. c. Carried by and capable of being rotated
in the brackets b. c. respectively are axles d. e. fast upon which axles d. e. are
mounted discs f. g. respectively. Fast with the plate or disc f is a crank-pin h.
carried by which and free to be turned thereon is an arm j. Carried by the arm j. is
a stuk which is embraced by the upper end of a rod 1. the lower end of which is
jointed to a lever m. carried by and free to be turned on a stud n. carried by a
bracket secured to the end frame a' of the loom. To the lever m is jointed the lower
end of a connecting rod o secured at its upper end to the rising and falling shuttle-
boxes p. The end k² of the stud k projects into a radial slot g¹ formed in the disc or
plate g.
Fast with the discs or plates f. g. respectively are pinions q. r. Carried by
the frame a is an axle s mounted fast upon which is a boss s upon which are formed
levers or arms t. u. Jointed to the lever or arm u is a toothed rack » capable of at times
gearing with the pinion q. Jointed to the lever or arm u is a toothed rack capable
of at times gearing with the pinion r. To the end u¹ of the lever or arm u is jointed one
end of a connecting rod w which at its lower end embraces a crank-pin projecting
from an arm y. fast upon the tappet shaft z. or other suitable shaft of the loom.
The rotation of the crank-pin a will cause the levers or arms t. u. to be oscillated about
the axis of the axle s. and the racks e. ¹ to be raised and lowered. Carried by the
frame a is a shaft 9 upon which and free to be oscillated thereon are bell-crank-
levers 7, 8. The bell-crank-levers 7, 8, are provided with catches by which the
discs f. g. are at times prevented from rotating.
1. 2. are darts or needles supported by and capable of being slidden longitudinally
in brackets 3. 3ª formed on the frame a. The needle or dart 1 is formed with a
shoulder 1 which abuts against the lower arm of the bell-crank-lever 7 and the end 1*
of the said dart or needle 1 abuts against the back of the toothed rack v. The dart or
needle 2 is formed with a shoulder 2 which abuts against the lower arm of the
bell-crank-lever 8 and the end 2ª of the said dart or needle 2 abuts against the back
of the toothed rack v¹.
The racks . ' being situate to one side of the axes of the studs upon
which they
are respectively mounted, tend to turn away from the pinions q. r. into which they
respectively gear. Carried by the frame a is a shaft or stud 10 mounted upon which
is a frame 10 in which and capable of being rotated therein is a barrel 11. around
which passes a pattern-card-chain 12 indicated by dotted lines only, in Figs. 1 and 4.
A portion of the pattern-card-chain 12 is shown detached in Fig. 1.
Fast upon the axle s is an arm s² provided with a studs which studs by the
oscillation of the arm s² is oscillated in the plane of the noggin wheel 13 mounted
upon the axle of the barrel 11.
The frame 10 is caused to oscillate upon the stud or shaft 10 by means of a
cam 14 mounted fast upon the tappet shaft z or any other suitable shaft of the
loom and by means of a spring 15. The cam 14 by acting against a bowl 16
mounted upon an arm 17 formed upon the frame 10ª causes the frame 10" to be
oscillated in the direction indicated by the arrow A. The spring 15 is secured at
one end to the end framing a¹ of the loom and at the other end to the arm 17.
When the arms and stud s³ are by the oscillation of the axle s being moved
in the direction indicated by the arrow A' the frame 10ª will be moving in the
direction indicated by the arrow A² and the stud s³ passing into one of the recesses

page_text: in the noggin wheel 13 will cause such noggin wheel 13 to be turned a portion of a
revolution in the direction indicated by the arrow A³. When the arm s² is moving
in a direction opposite to that indicated by the arrow A' and the frame 10ª is
moving in a direction opposite to that indicated by the arrow A² the stud s³ will
pass above and clear of the noggin wheel 13.
When the frame 10" is caused to move in the direction indicated by the arrow A.
the pattern-chain 12 passing around the barrel 11, will be moved towards the darts or
needles 1. 2. and thus at times cause one or other or both of the darts or needles 1. 2.
to be moved longitudinally in the direction indicated by the arrow B. When either
of the darts or needles 1. 2. is moved longitudinally in the direction indicated by the
arrow B. the toothed rack used in conjunction with such needle or dart will be turned
in the direction indicated by the arrow C. and into gear with the pinion used in
conjunction with such rack.
"
The said rack having been caused to gear with the said pinion, and the said rack
having been raised to its highest position by the revolution of the crank-pin a a
continued revolution of the crank-pin a will by causing the descent of such rack cause
the said rack to turn the pinion and disc in conjunction with which it is used in the
direction indicated by the arrow D. and by means of the said disc cause the shuttle-
boxes p to be " changed as described in the specification filed in respect of our
application for the patent hereinbefore referred to. When the said rack which has
geared with the pinion has completed its downward movement the turning of the
frame 10 and chain-barrel 11. in the direction opposite to that indicated by the
arrow A. will cause the pattern-card-chain 12 to recede from the darts or needles 1. 2.
and allow the dart or needle or darts or needles previously forced in the direction
indicated by the arrow B. to be moved in a direction opposite to that indicated by the
arrow B. by means of one or other of the springs 18. 19. which act respectively against
the lower ends of the bell-crank-levers 7. 8. and turn such bell-crank-levers 7. 8. in
the direction indicated by the arrow E. The springs 18. 19. are shown detached in
Fig 1.
When the said dart or needle or darts or needles has or have been withdrawn from the
toothed rack or toothed racks upon which it or they previously acted the said toothed rack
or toothed racks will fall away from and out of gear with, the pinion or pinions which
it or they had previously acted on. The racks v. moving freely up and down clear
of the pinions on which they respectively at times act, will only act upon such
pinions when caused to gear with such pinions by the darts or needles 1. 2. being
forced in the direction indicated by the arrow B. by the pattern-chain 12. When
either of the needles or darts 1. 2. is moved in the direction indicated by the arrow B.
the catch upon the corresponding bell-crank-lever 7 or 8 as the case may be, will
be removed from the disc for g which it previously prevented from rotating. When
the loom is turned backward for any purpose the pattern-card-chain 12 and, it may
be, one or other or both of the discs f. g. will also be turned backward and thus
the pattern-card-chain 12 and shuttle-boxes p. will be maintained in proper position
relatively to the pattern of the "piece" or "cloth" being woven in the loom.
A further part of our invention relates to arrangements of apparatus for operating
the pattern-card-chain used for causing or controlling the raising and lowering of the
shuttle-boxes and this part of our invention is particularly applicable for use in
weaving patterns in which one portion of the pattern occurs at intervals and another
portion is repeated several or a considerable number of times in succession. In
carrying this part of our invention into effect we employ for causing or controlling
the raising or lowering of the shuttle-boxes, a pattern-chain which may be moved in
one direction or the other or alternately in both directions or remain stationary as
may be necessary or desirable for producing the pattern required to be produced. In
order to perform this part of our invention we employ a "lag barrel" around which
is passed a governing chain formed of suitable lags or plates. The said "lag barrel "
is mounted upon a stud upon which the said "lag barrel" is capable of being
rotated. Fast upon the said "lag barrel" is a toothed wheel. The pattern-card-
chain before mentioned at times acts upon a dart or needle capable of being slidden

page_text: in guides. The said dart or needle is moved longitudinally in one direction by the
pattern-card-chain and in the other direction by means of a weight or spring.
The dart or needle above mentioned is connected in any suitable manner to a
toothed rack to which rack we impart a to and fro longitudinal motion by means
of the lever or arms previously referred to and employed for moving to and fro
longitudinally the racks which act upon the discs by which the shuttle-boxes are
raised and lowered. When the dart or needle is acted upon by the pattern-card-chain
the rack above mentioned will be caused to engage with the wheel fast with the
"lag barrel" before mentioned and thereby cause the "lag barrel" to be at times
turned.
Fig. 6 is a side elevation of so much of a loom as is requisite to illustrate this
part of our invention. Fig. 7 is a section of a portion of that which is shewn
in Fig. 6. Fig. 8 is an end elevation, Fig. 9 is a side elevation and Fig. 10 a
plan showing a portion of that which is shown in Fig. 6. Figs. 8, 9 and 10 are
upon a larger scale than Figs. 6 and 7.
In carrying this part of our invention into effect we employ parts similar to those
which are employed in carrying the first part of our invention into effect, such parts
being employed in conjunction with certain other parts to be hereinafter described.
To the parts which are similar to parts which have been previously described in
reference to the first part of our invention we shall apply the same letters of
reference as were applied to the like parts described in reference to the first part of
our invention.
Carried by the frame a is a stud 20 upon which is mounted a lag barrel 21
around which passes a lag chain 21. The lag chain 21ª is formed of lags of three
different heights such as the lags 21° 21° and 21ª.
Fast with the "lag barrel" 21 is a toothed wheel 22. 23 is a needle or dart
supported by and capable of being moved longitudinally in holes formed through the
brackets 3. 3ª.
Fast upon the needle or dart 23 is an arm 23ª one end of which passes through
a slot 28 formed in a toothed rack 28 jointed at its lower end to the lever or arm t.
The teeth of the toothed rack 28 are capable of at times gearing into the teeth of
the wheel 22.
Secured to the frame a is a stud 29 upon which and free to be turned thereon is
a bell-crank-lever 30. To one end of the bell-crank-lever 30 is secured a bar or
finger 31 which projects over and is supported by the lags of the "lag chain
" 21º.
Upon one end of the bell-crank-lever 30 are formed jaws 32 which pass into a groove
formed in a collar 33 fast upon an axle 34 supported by and capable of being
slidden and turned in holes formed in the frame a.
Fast upon the axle 34 is an arm 35 secured to which are projecting studs 36. 37.
In the jarim 35 is formed a slot 35*, into which passes a pin 38 fast upon an arm 39,
secured upon the axle s.
Fast upon the axle of the pattern-chain-barrel 11. is the noggin wheel 13. and also
fast upon the said axle is a toothed wheel 41 which gears into a toothed wheel 42
carried by and free to be turned upon a stud secured to a bracket 43 secured to the
frame 10. Fast with the toothed wheel 42 is a noggin wheel 44. The noggin
wheels 13 and 44 the studs 36 and 37, and the toothed wheels 41 and 42 are shown
more clearly in Fig. 8ª. When the axle s is oscillated by the revolution of the crank-
pin the arm 39 and pin 38 will by means of the slot 35° cause the arm 35 to be
oscillated about the axis of the axle 34. Such oscillation of the arm 35 will, as will
be hereinafter pointed out cause either the stud 36 to pass into the notches of the
noggin wheel 13 so as to rotate such noggin wheel 13 or will cause the stud 37 to
pass into the notches of the noggin wheel 44 so as to rotate such noggin wheel 44.
When the axles is oscillated in the direction indicated by the arrow F the pin 38
will cause the arm 35 to be oscillated in the direction indicated by the arrow G.
When the axle s is oscillated in a direction opposite to that indicated by the arrow F.
the pin 38 will cause the arm 35 to be oscillated in a direction opposite to that indicated
by the arrow G

page_text: When the arm 35 is being oscillated in the direction indicated by the arrow G.
and carrying the stud 37 in the plane in which the noggin wheel 44 is moving the
stud 37 will pass into the notches of the noggin wheel 44 and cause such noggin
wheel 44 to be turned in the direction indicated by the arrow H. When the arm 35
is being oscillated in the direction indicated by the arrow G. and carrying the stud 36
in the plane in which the noggin wheel 13 is moving, the stud 36 will pass into the
notches of the noggin wheel 13 and cause such noggin wheel 13 to be turned in the
direction indicated by the arrow J.
When the stud 37 turns the noggin wheel 44 in the direction indicated by the
arrow H. the pattern-chain-barrel 11. will be turned by means of the wheels 42. 41.
in a direction opposite to that indicated by the arrow J. The noggin wheel 44 will
during each revolution of the shaft z be rotated through one quarter of a revolution
in the direction indicated by the arrow H. and so long as plates of the pattern-card-
chain 12 having perforations which can pass over the end of the dart or needle 23
are presented to the dart or needle 23 such dart or needle 23 will not be acted upon,
but if a plate of the pattern-card-chain 12, the portion 12ª of which is imperforate
such as for instance the plate 12b, arrive opposit: the dart or needle 23 such dart or
needle 23 will by the next oscillation of the frame 10" in the direction indicated by
the arrow A³ be moved in the direction indicated by the arrow B. and will cause the
arm 23 to be moved in the direction indicated by the arrow B and thus the teeth of
the rack 28 will by means of the slots 28" be caused to gear or engage with the teeth
of the wheel 22. The needle or dart 23 is moved in the direction opposite to that
indicated by the arrow B. by means of the spring 23 shown in Fig. 6.
The downward movement of the rack 28 will turn the "lag barrel" 21 in the
direction indicated by the arrow L and cause the next lag of the lag chain 21" to be
brought into position beneath the bar or finger 31. A typical portion of the pattern-
chain or card-chain 12 is shown detached in Fig. 6ª of the accompanying drawings.
To retain the "lag barrel "21 in position after it has been turned by the toothed
rack 28 we secure to the "lag barrel" 21 a dise 40 having around its eige as many
flattened portions as there are notches in the "lag barrel" 21 to receive the lags of
the lag chain 21. Secured to the frame a is a spring a² the end of which bears upon
the flattened portions of the disc 40. The spring a² and disc 40 are shown in Figs. 11
and 12 of the accompanying drawings.
Should a lag such as 21ª have been brought into position beneath the bar or
finger 31 by the rotation of the lag barrel 21 the bar or finger 31 will by
its weight be caused to descend and rest upon such lag 21. Such movement
of the bar or finger 31 will cause the jaws 32 of the bell-crank-lever 30 to move
the axle 34 and arm 35 in the direction indicated by the arrow M. thereby
removing the stud 36 from the plane in which the noggin wheel 13 moves and
bringing the stud 37 into the plane in which the noggin wheel 44 moves. The next
movement of the arm 35 in the direction indicated by the arrow G will cause the
stud 37 by passing into the notches of the noggin wheel 44 to turn such noggin
wheel 44 in the direction indicated by the arrow J. and cause the pattern-cbain-
barrel 11 to be rotated in a direction opposite to that in which it is rotated when the
stud 36 acts upon the noggin wheel 13.
When the rotation of the lag barrel 21 brings a lag such as 21" beneath the bar
or finger 31 the bell-crank-lever 30 will be turned and move the axle 34 and arm 35
into such position that the studs 36. 37. will when oscillating move clear of the
noggin wheels 13. 44 and at such times the pattern-chain-barrel 11. will not be rotated.
Upon the next movement of the pattern-card-chain 12 in the direction indicated
by the arrow B, the blank portion 12ª of the plate 12 of the pattern-card-chain 12
will again act upon the needle or dart 23 and so cause another lag of the "lag
chain" 21" to be brought beneath the bar or finger 31 and such lag may either cause
the pattern-chain-barrel 11 to be turned in one direction or another or may allow the
pattern-chain-barrel 11 to remain unturned.
By the above described arrangements we are enabled to cause the pattern-card-
chain 12 to be turned forward or backward or to cause such pattern-card-chain 12

page_text: to remain stationary as may be desired and we are thus enabled to employ in weaving
a given pattern a pattern-card-chain of less length than would otherwise be required
for weaving such pattern. When the arm 35 is making its return movement in a
direction opposite to that indicated by the arrow G the studs 36 and 37 will pass
clear of the noggin wheels 13 and 44.
When the loom is being turned "backward" the studs 36, 37, will pass clear of
the noggin wheels 13 and 44 when the arm 35 is moving in the direction indicated by
the arrow G.
"
When the loom is turned "backward
for any purpose the pattern-card-chain 12
and, it may be, one or other or both of the discs f. 9. and, it may be, the lag chain 21*
will also be turned backward and thus the pattern-card-chain 12. lag-chain 21" and
shuttle-boxes P will be maintained in proper position relatively to the pattern of the
piece" or "cloth" being woven.
"
The chain barrels employed in looms constructed according to our invention may
be prevented from being moved except when required, by means of any suitable
appliances such for instance, as that illustrated in Figs. 83 and 8°.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed we declare that what
we claim is :-
1. The hereinbefore described arrangements of apparatus for turning one or other or
