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 firstly to such looms for weaving cotton and other fabrics as
are provided with what are known as "rising and falling shuttle boxes" and our
Invention consists firstly in arrangements of apparatus for raising and lowering the
፡፡ rising and falling shuttle boxes."
According to the first part of our Invention we provide each loom with two discs
placed opposite to each other, each of which discs is provided with a shaft capable of
being rotated in brackets secured to the framework of the loom. We provide one of
the said discs with a slot or groove and provide the other of such discs with a stud or
pivot upon which and capable of being turned thereon is an arm from which projects
a stud or crank-pin, one end of which stud or crank-pin passes into the slot or groove
above mentioned. Embracing the stud or crank pin before mentioned is one end of
a rod the other end of which is connected by means of a stud to a lever capable of
being turned upon a stud secured to the framework of the loom. To the lever before
mentioned is jointed one end of a rod the other end of which is connected to the
rising and falling shuttle boxes" of the loom. If the two discs above mentioned be
turned an equal amount in the same direction the stud or crank-pin will be retained at
the same distance from the axis of rotation of the discs before mentioned but if one
disc be turned through a portion of a revolution and the other disc be caused to
remain stationary or be turned through a greater or less portion of a revolution than
the disc aforesaid the arm carrying the stud or crank-pin will be turned around the
axis of the stud or pivot by which it is carried and the stud or crank-pin will be caused
to recede from or approach the axis of the disc by which such crank-pin is carried, the
slot or groove formed in the disc above mentioned allowing the end of the stud or
crank-pin passing into such slot or groove to recede from or approach the axis of the

page_text: disc in which such slot or groove is formed. The sides of the slot or groove aforesaid
serve at times to transmit motion to the stud or crank-pin above mentioned and serve
at other times to retard or hold back, such stud or crank-pin. Upon.a boss on each of
the brackets which support the shafts upon which the discs above mentioned are
mounted and free to be rotated thereon is a toothed pinion which by means of a pawl
or click at times imparts motion to the disc upon the shaft upon which the said toothed
pinion is mounted. Capable of being slidden longitudinally in suitable guides are
two toothed racks, the teeth of one of such toothed racks "gearing" with the teeth
of one of the toothed pinions above mentioned and the teeth of the other toothed rack
gearing" into the teeth of the other toothed pinion.
66
One end of each of the toothed racks before mentioned is supported upon one end
of a bell-crank-lever the other end of which bell-crank-lever is jointed to one end of
a rod or needle supported in suitable guides in which it may be slidden.
The other end of each of the rods or needles above mentioned is opposite to a barrel
around which passes a
pattern chain." Each of the bell-crank-levers above referred
to is provided with a tooth which when the bell-crank-lever is in one position passes
into a notch in the disc in conjunction with which such bell-crank-lever is used and
so prevents the disc at times from being turned. The rods or needles before
mentioned are provided with springs by which they are forced in a direction towards
the "pattern-chain" such springs also tending to keep the ends of the toothed racks
upon which the bell-crank-levers act in an elevated position.
The barrel around which passes the "pattern-chain" above mentioned is
carried in a frame or cradle which is caused to oscillate upon a stud or pivot
by means of a connecting-rod which receives motion from any convenient
part of the loom. Fast upon the axle of the "barrel" before mentioned, is a toothed
wheel and resting upon such toothed wheel is a pawl or click the other end of
which turns upon a pin secured to the framework of the loom, or to any other
convenient part. As the frame carrying the barrel before mentioned oscillates, the
pawl or click will cause the barrel to turn and bring a 'fresh card" opposite to the
rods or needles before mentioned. The upper end of the frame before mentioned is
provided with a bar or rib which at certain times passes into notches or recesses,
formed in the toothed racks previously mentioned. When. the loom is at work and a
change of shuttle is required to take place, the barrel around which the pattern-chain
passes, will by being rotated bring a plate of the pattern-chain opposite to the rods or
needles before referred to, which plate will, by the oscillation of the frame or cradle
before referred to, be caused to act against one or both of the rods, or needles, according
to the change of shuttle required.
We shall in the first instance, refer to the case in which both of the rods or needles
are acted upon by the plate of the pattern-chain, in which case the plate of the
pattern-chain will, by the movement of the frame or cradle be caused to push the rods
or needles so as to turn the bell-crank-levers so as to allow the toothed racks to descend
so that the notches or recesses therein will embrace the bar or rib upon the frame or
cradle so that when the frame or cradle moves away from the rods or needles the discs
will be turned through half a revolution, carrying with them the stud or crank-pin
previously mentioned. The above described descent of the bell-crank-lever will by
removing the tooth from the notches in the, discs before referred to, leave the discs at
liberty to be turned. When one only of the rods or needles before referred to is acted
upon by the pattern chain, only one of the discs will be rotated, in which case, the
stud or crank pin will be caused to approach or recede from the axis of the disc by
which it is carried and the shuttle boxes will be raised or lowered. By appropriately
arranging the plates of the pattern-chain so that either one or other or both of the
rods or needles before referred to will be acted upon, the shuttle boxes may be brought
into the positions required in weaving. The above described arrangement of
apparatus is applicable to looms in which four "shuttle boxes "are employed, but by
placing another similar apparatus in addition to that above described and connecting
such apparatus to the rod by which the shuttle boxes are "raised" or "lowered" our
Invention may be employed in looms having any number of shuttle boxes..

page_text: In some cases, we cause the weft fork to render the pattern-chain inoperative, when
the weft breaks or becomes absent, the weft fork then moving the catch by which the
barrel around which passes the pattern-chain, is rotated.
We have above referred to a slot or groove as being provided in one of the discs
above mentioned, but in place of such slot or groove a rib or projection may be
employed and in such cases the stud or crank-pin before mentioned is made so as to
be capable of being turned around its axis, and is formed so that it will engage with
the said rib.
A further part of our Invention relates to looms in which what are known as
rising or falling shuttle boxes" are employed, and consists in a method of operating
the pattern-chain or pattern-cards used for causing or controlling the raising and
lowering of the shuttle boxes and this portion 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 portion of our Invention into effect, we employ for
causing or controlling the raising and 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. The said pattern-chain may be of any construction. To operate the
pattern-chain as above described, we pass such pattern-chain around a barrel or roller
or other suitable means which barrel or roller or other suitable means, we actuate by
means of levers, or a chain or chains or suitable gearing, which are or is so acted upon
by a governing pattern-chain of any construction that the levers, chain or chains or
suitabie gearing will cause the barrel or roller or other convenient means to be turned
in one direction or the other or remain stationary as may be desired.
This portion of our Invention enables us to employ a very short operative pattern-
chain, or very few cards in weaving many patterns which have hitherto required very
long pattern-chains-or very many cards to be employed.

Improvements in Looms in which what are known as Rising and
Falling Shuttle Boxes" are Employed.
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 manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:
Our invention relates firstly to such looms for weaving cotton and other fabrics
as are provided with what are known as "rising and falling shuttle boxes" and our
invention consists firstly in arrangements of apparatus for raising and lowering the
rising and falling shuttle boxes.
According to the first part of our invention we provide each loom with two discs
placed opposite to each other each of which discs is provided with a shaft capable of
being rotated in brackets secured to the framework of the loom.-We provide one of
the said dises with a slot or groove and provide the other of such discs with a stud
or pivot on which and capable of being turned thereon is an arm from which
projects a stud or crank-pin one end of which stud or crank-pin passes into the slot
or groove above mentioned. Embracing the stud or crank-pin before mentioned
is one end of a rod the other end of which is connected by means of a stud to a
lever capable of being turned upon a stud secured to the framework of the loom.
To the lever before mentioned is jointed' one end of a rod the other end of which
is connected to the "rising and falling shuttle boxes" of the loom. If the two discs
above mentioned be turned an equal amount in the same direction the stud or
crank-pin will be retained at the same distance from the axis of rotation of the
discs before mentioned but if one disc be turned through a portion of a revolution
and the other aisc be caused to remain stationary the arm carrying the stud or crank-
pin will be turned around the axis of the stud or pivot by which it is carried and the
stud or crank-pin will be caused to recede from or approach the axis of the disc by
which such crank-pin is carried, the slot or groove formed in the disc above mentioned
allowing the end of the stud or crank-pin passing into such slot or groove to recede
from or approach the axis of the disc in which such slot or groove is formed.
The sides of the slot or groove aforesaid serve at times to transmit motion to the
stud or crank-pin above mentioned and serve at other times to retard or hold back
such stud or crank-pin. Upon a boss on each of the brackets which support the
shafts upon which the discs above mentioned are mounted and free to be rotated
thereon is a toothed pinion which by means of a pawl or click at times imparts motion
to the disc upon the shaft upon which the said toothed pinion is mounted.
Capable of being slidden longitudinally in suitable guides are two toothed racks the
teeth of one of such toothed racks "gearing" with the teeth of one of the toothed pinions
above mentioned and the teeth of the other toothed rack "gearing" into the teeth of
the other toothed pinion. One end of each of the toothed racks before mentioned is
supported upon one end of a bell-crank-lever the other end of which bell-crank-lever
is jointed to one end of a rod or needle supported in suitable guides in which it may

page_text: be slidden. The other end of each of the rods or needles above mentioned is opposite
to a barrel around which passes a "pattern chain." Each of the bell-crank-levers
above referred to is provided with a tooth which when the bell-crank-lever is in one
position passes into a notch in the disc in conjunction with which such bell-crank-lever
is used and so prevents the disc at times from being turned. The rods or needles
before mentioned are provided with springs by which they are forced in a direction
towards the "pattern chain "such springs also tending to keep the ends of the toothed
racks upon which the bell-crank-levers act in an elevated position. The barrel around
which passes the "pattern-chain" above mentioned is carried in a frame or cradle
which is caused to oscillate upon a stud or pivot by means of a connecting-rod which
receives motion from any convenient part of the loom. Fast upon the axle of the
"barrel" before mentioned is a toothed wheel and resting upon such toothed wheel is
a pawl or click the other end of which turns upon a pin secured to the framework of
the loom or to any other convenient part. As the frame carrying the barrel before
mentioned oscillates the pawl or click will cause the barrel to turn and bring a "fresh
card" opposite to the rods or needles before mentioned. The upper end of the
frame before mentioned is provided with a bar or rib which at certain times passes
into notches or recesses formed in the toothed racks previously mentioned. When
the loom is at work and a change of shuttle is required to take place the barrel
around which the pattern-chain passes will by being rotated bring a plate of the
pattern-chain opposite to the rods or needles before referred to, which plate will by
the oscillation of the frame or cradle before referred to, be caused to act against one
or both of the rods or needles according to the change of shuttle required.
We shall in the first instance refer to the case in which both of the rods or
needles are acted upon by the plate of the pattern-chain in which case the plate
of the pattern-chain will by the movement of the frame or cradle be caused to
push the rods or needles so as to turn the bell crank-levers so as to allow the
toothed racks to descend so that the notches or recesses therein will embrace the
bar or rib upon the frame or cradle so that when the frame or cradle moves away
from the rods or needles the discs will be turned through half a revolution carrying
with them the stud or crank-pin previously mentioned. The above described turning
of the bell-crank-lever will by removing the tooth from one of the notches in the
disc in conjunction with which such bell-crank-lever is employed leave such disc at
liberty to be turned. When one only of the rods or needles before referred to is
acted upon by the pattern-chain only one of the discs will be rotated in which caso
the stud or crank-pin will be caused to approach or recede from the axis of the disc
by which it is carried and the shuttle-boxes will be raised or lowered. By appropriately
arranging the plates of the pattern-chain so that either one or other or both of the
rods or needles before referred to will be acted upon, the shuttle boxes may be brought
into all the positions required in weaving.
In some cases we cause the "weft fork" to render the pattern-chain inoperative
when the weft breaks or becomes absent.
We have above referred to a slot or groove as being provided in one of the discs
above mentioned but in place of such slot or groove a rib or projection may be
employed and in such cases the stud or crank-pin before mentioned is made so as to
be capable of being turned around its axis and is formed so that it will engage with
the said rib.

In the accompanying drawings Fig. 1 is a side view of a portion of a loom-Fig. 2
is an end view. Fig. 3 a plan and Fig. 4 a section of a portion of that which is shown
in Fig. 1 and Figs. 5 to 28 inclusive, are views of portions shown detached for
convenience of illustration. The same letters of reference are applied to corresponding
parts throughout the whole series of figures.
a is one end-framing of the loom to which end-framing a is secured a bracket b
formed upon or secured to which are extended parts 61, 62. To the part is secured
a bracket c. carried by which and capable of being rotated therein is a short shaft d
formed upon or secured to which is a disc e. The shaft is prevented from moving
longitudinally by means of. the disc e and a collar d' secured upon such shaft d. To

page_text: "
the part 6 is secured a bracket f carried by and.capable of being rotated in which is
a short shaft g formed upon or secured to which is a disc h. The shaft g is prevented
from moving longitudinally by means of the disc h and a collar g' secured upon the
shaft g. The face of the disc h is provided with ribs ¹ between which is a slot or
groove A. Secured to the disc e is a stud or pin e' upon which and free to be turned
thereon is an arm j.-To the arm is secured a stud or crank-pin k the end of which
stud or crank-pin k projects into the slot or groove A. The stud or crank-pin k is
embraced by the end of a rod Z jointed at its lower end to a lever m carried by and
capable of being turned upon a stud m' secured to the end-frame a-Secured to the
'lever m is a stud in² to which is jointed the lower end of a rod n the upper end of
which is connected to the frame o of the shuttle boxes o¹, 02, 03, 01.
q
Upon the shaft d and at times free to be rotated thereon is a pinion p the teeth of
which take into or engage with the teeth of the toothed rack q one end of which is
formed with a notch or recess q'. The end q² of the toothed rack 9 passes through
guides formed in brackets secured to the part 1. In the shaft d is formed a recess
in which recess is situate a detent forced outwards from the shaft d by means of a
spring shown more particularly in Fig. 6. The detent is at times caused by the
said spring to pass into recesses p³ formed in the pinion p. The detent ? is formed
with an incline which when the pinion p is turned in a direction opposite to that
indicated by the arrow B causes the detent to compress the spring above mentioned
and pass into the shaft d and thus leave the pinion p at liberty to be turned in the
direction opposite to that indicated by the arrow B. When the toothed rack is
moved in the direction indicated by the arrow C the pinion p will be caused to
rotate and will by means of the- detent r cause the disc e to be rotated in the
direction indicated by the arrow B. When the toothed rack 9 is moved in a
direction opposite to that indicated by the arrow the pinion p will be rotated
without imparting motion to the shaft d. Upon the shaft g and at times free to be
rotated thereon is a pinion s the teeth of which take into or engage with the teeth of
the toothed rack tone end of which is formed with a notch or recess t¹ indicated
only by dotted lines in Fig. 3. The end 2 of the toothed rack t passes through guides
forined on a bracket secured to the part 2. In the shaft g is formed a recess in
which is situate a detent u forced outwards from the shaft g by means of a spring.
The detent is caused at times by the said spring to pass into recesses formed in the
pinion s. The detent u is formed with an incline which when the pinion s is turned
in a direction opposite to that indicated by the arrow B causes the detent u to
compress the spring above mentioned. and pass into the shaft g and thus leave the
pinions at liberty to be turned in the direction opposite to that indicated by the
arrow B. When the toothed rack t is moved in the direction indicated by the
arrow C the pinion s will bo caused to rotate and will by means of the detent u cause
the disc to be rotated in the direction indicated by the arrow B. When the toothed
rack 't is moved in a direction opposite to that indicated by the arrow C the detent u
will be forced into the recess in which it is situate against the force of the spring
aforesaid by the boss of the pinion s so that the pinions may be rotated in the
direction opposite to that indicated by the arrow B without causing the shaft g to.
be rotated. In the circumference of the disc e are formed recesses e, e³ shown in
Fig. 6. Mounted and free to be turned upon a bar 64 carried by the bracket b iş
a bell-crank lever one end of which is provided with a tooth w which at times
passes into the recesses e², e³. Jointed to the end v¹ of the lever v is a needle a which
passes through and is guided by a hole formed in a bracket 6 secured to the
bracket b. Upon the needle x is mounted a spring ¹ one end of which abuts against
the bracket 65 while the other end of the spring a abuts against a collar on the needle z.
The spring tends to force the needle in the direction indicated by the arrow D
and retain the tooth w in one or other of the notches e³, e. Mounted upon the
bar is a bell-crank-lever y the end y₁ of which is provided with a tooth which
at times passes into notches h h³ formed in
to the end y of the lever y is a needle
hole formed in the bracket 5 secured to
the circumference of the disc h. Jointed
which passes through and is guided by a
the bracket b. Upon the needle is

page_text: mounted a spring
one end of which abuts against the bracket while the other
end of such spring abuts against a collar upon the needle. The spring ¹
tends to force the needle z in the direction indicated by the arrow D and rotain the
tooth upon the end y¹ of the bell crank lever y in one or other of the notches h², h³
in the disc h. 1 is a frame supported by and capable of being oscillated upon a
bar 2 supported by arms formed on the bracket b. Jointed to an arm 1 formed
on the frame 1 is one end of a connecting-rod 3. Upon the tappet shaft 4 or other
convenient and suitable shaft of the loom we mount a crank-pin 5 which at times
acts against an abutment 3" formed on the connecting-rod 3 which abutment 3 is
retained against the crank-pin 5 by means of the springs 3. Mounted in bearings
upon the frame 1 is the axle 6 of a barrel 6 upon which is mounted a pattern-
chain 7. The barrel 6 is provided with pins which "drive" the pattern-chain 7 by
passing into holes formed in the links of the said pattern-chain 7. The revolution of
the crank-pin 5 will cause the frame 1 to be oscillated upon the bar 2. For
the purpose of this part of our invention the chain-barrel 6 may be rotated by any
ordinary or convenient appliances. Fast with the bell-crank-lever v is an arm v
upon which rests the toothed rack g. The arm v² is formed with ears which.
prevent the toothed rack from moving laterally. Fast with the bell-crank-lover y
is an arm y³ upon which rests the toothed rack t. The army is formed with ears
which prevent the toothed rack t from moving laterally.

In the position in which the parts are shown in the accompanying drawings "picking"
is taking place from the box o*. We will assume that the next link of the pattern-
chain 7 presented to the needles, z by the barrel 6 will present a blank portion
to the needle x. The oscillation of the frame 1 will bring the blank portion of the
said link of the pattern-chain. 7 against the needle and a further movement of the
frame 1 in the direction indicated by the arrow E will cause a bar 11 which
extends across between the upper ends of the frame 1 to pass beneath the toothed
racks q, t. The blank part of the said link of the pattern chain 7 arriving against
the needle will push it in a direction opposite to that indicated by the arrow D.
and cause the bell-crank-lever u to be turned in the direction indicated by the
arrow F and raise the tooth. . clear of the. recess or notch ein the disc .e and.
will by the descent of the arm 2 allow the notch or recess 71 to engage with the
bar 11. When the bar 11 by the movement of the frame 1 is moved in a direction
opposite to that indicated by the arrow E the toothed rack will be drawn in
the same direction and the pinion p will by means of the detent. r turn the disc e
until the recess arrives beneath the tooth w. The continued movement of the
frame 1 in the direction opposite to that indicated by the arrow E will have allowed
the spring to move the needle x until the collar upon the needle a arrives
against the bracket 6 when the movement of the needle z will have caused the
arm to be raised. The turning of the disc e in the direction indicated by the
arrow B will have carried the stud or crank-pin k from the position in which it is
shown in the accompanying drawings to a fresh position and will allow the lever m
to descend so as to bring the box o³ into position for receiving a shuttle or for.
having a shuttle thrown from it.
The rack is shown detached and in side view in Figure 7. Upon the said,
rack is formed a raised part q³ connected by an inclined part of to a straight
portion When the rack 7 is in the position in which it is indicated in Fig. 6
the raised part q³ rests upon the outer end of the arm 2. The rack is similar in
construction to the rack q and the raised portion of such rack t corresponding to
the part q rests upon the outer end of the arm y³ of the bell-crank-lever y when
the rack is in the position in which it is indicated in Fig. 3.
The partial rotation of the disc e in the direction indicated by the arrow B will
have carried the notch e beneath the tooth w which passing into the notch e will
hold the disc e in position until another change in the position of the disc e is
required to take place. Simultaneously with the passage of the tooth winto the
recess the bar 11 will have completed its movement in the direction opposite to
that indicated by the arrow E. The movement of the frame 1 in the direction
.

page_text: q
in the
indicated by the arrow E causing the bar 11 to act against the rack q will move such
rack q in the direction opposite to that indicated by the arrow C and such movement
of the rack will carry the raised part q³ on to the lever and if the needle has not
been acted upon by the pattern-chain 7 so as to turn the bell-crank-lever
direction indicated by the arrow H the portion q of the rack will be held clear
of the bar 11 and the next movement of the frame 1 in the direction opposite to that
indicated by the arrow E will leave the rack in the position in which it is
indicated in the drawing such position being that in which the rack 9 was left when
the frame 1.completed its movement in the direction indicated by the arrow E.
The above described change in the position of the boxes o¹, o³, o³, of was effected
by causing by means of the toothed rack 'g the disc e to perform half a revolution. We
will now assume the parts to be in the positions in which they are indicated in the
drawings and a blank portion of one of the links of the pattern-chain 7 to be caused
to act upon the needle so as to push it in the direction opposite to that indicated
by the arrow D. The rack t, arm y³ and lever y will then be acted upon and caused
to operate in a manner similar to that described in reference to the rack q, arm v²
and lover and cause the disc h to be partially rotated.
By the pattern-chain 7 being arranged to act upon 'the needle x or the needle z
the
disc e or the disc has the case may be may be caused to be partially rotated.
and by the pattern-chain 7 being caused to act upon both of the needles x, z both
of the discs e. h. may be caused to be partially rotated and by the discs e, h: being
caused to rotate together or separately the stud or crank pin k may be caused to
occupy the positions in which it is illustrated in the diagrams Figs. 8, 9, 10, 11,
12, 13, 14 and 15. When the stud or crank-pin k is in the position in which it
is indicated in Figs. 8 and 9 the box o¼ will be in position for delivering or receiving
a shuttle. When the stud or crank-pin k is in the position in which it is indicated
in Figs. 10 and 11 the box o³ will be in position for delivering or receiving a shuttle.
When the stud or crank-pin k is in the position in which it is indicated in. Figs. 12
and 13 the box o² will be in position for delivering or receiving a shuttle. When
the stud or crank-pin k is in the position in which it is indicated in Figs. 14 and 15
the box o will be in position for delivering or receiving a shuttle.
When the disc h is rotated and the disc e remains stationary the shuttle boxes. o!
0203, 0¹ will be moved so that the next box but one above or below will be brought
into position for receiving or delivering a shuttle.
When the disce is rotated and the disc h remains stationary the shuttle boxes o¹
02, 03, 0 will be moved so that the next box higher or lower will be brought into
position for receiving or delivering a shuttle.
By the movements of both of the discs e. h being combined or the disc e being
rotated while the disc is stationary or the disc being rotated while the disc e, is
stationary the stud or crank-pin k may be placed in any of the positions in which it
is indicated in Figs. 8, 9, 10 11 12, 13, 14 and 15-as may be required for causing
any of the shuttle boxes o*, 03, 0², o¹ to be brought into position for delivering or
receiving a shuttle as may be desired.
When it is required to make what is commonly called a "full rise" the stud or
crank-pink will be turned from the position in which it is indicated in Figs. 14 and
15 to the position in which it is indicated in Figs. 8 and 9 by the discs e-and h being
rotated simultaneously and when it is required to make what is commonly called a
"full drop
"the stud or crank-pink will be turned from the position in which it is
indicated in Figs. 8 and 9 to that in which it is indicated in Figs. 14 and 15. We
place between the bracket c and the collar d', washers d² of indiarubber or other
suitable material and between the bracket fand, the collar we place washers 92 of
indiarubber or other suitable material such washers d², g of indiarubber or other
suitable material preventing the discs e, h from "over running" when being rotated.
Above the toothed racks q; t we place springs, such springs tending to keep the
racks.qt in position on the arms v², respectively. The nuts upon the rod
enable the shuttle boxes o¹, 02, 03, ot to be adjusted in position.

"
Such of the parts connected with the disc hand toothed rack t as are not clearly

page_text: shown in the accompanying drawings are similar to the corresponding parts connected
with the disc e and toothed rack y.
We propose in some cases to employ the arrangements shown in Figs. 16 17
and 18 for transmitting motion from the pinions p. s. to the discs e. h. In Fig. 16, a
pawl 12 is shown as being jointed to the pinion the end 12 of the said pawl 12 at
times acting against one or other of the teeth 13 formed in the disc-To ensure the
pawl 12 acting on one or other of the teeth 13 we employ a spring 14-In Fig. 17
the pawl 12 is shown as being jointed to the disc and in such cases we cause such
pawl 12 to act upon teeth 13 formed in the pinion.
We also propose in some cases to employ for the said purpose the arrangement
shown in Fig. 18 in which arrangement we employ a detent 15 forced forward by a
spring 16.
Extending across the loom and supported by and capable of being turned in
bearings formed in the side framings of the loom is a shaft 17 so connected to the stop
rod of the loom that when the stop rod is moved to stop the loom by the action of the
"weft stop motion" the shaft 17 will be turned in the direction indicated by the
arrow G.
Upon one end of the shaft 17 is mounted a lever 18 provided with a pin 19 which
projects into a slot formed in the arm 20° of a bell-crank-lever 20 mounted so as to
be capable of being turned upon the bar b.
Upon the arm 20° of the bell-crank-lever 20 is formed a catch 20° which is capablo
at times of passing upon the bar 11.
When the "weft stop motion" liberates the stop rod of the loom the shaft 17 will
be turned in the direction indicated by the arrow G, the catch 20° will be turned in
the direction indicated by the arrow H and the movement of the frame 1 will carry
the har 11 beneath the catch 20° into which it will pass. As soon as the bar 11 has
engaged with the catch 20° the frame 1 will be held stationary consequently no
further rotation of the chain barrel 7 can take place until the stop rod is placed in
position for starting the loom. The placing of the stop rod in position for starting
the loom will cause the catch 20° to bo withdrawn froin the bar 11. If while the
frame 1 is held stationary by the catch 20° any rotation of the crank-pin 5 takes
place the said crank-pin 5 will slide along between the connecting rod 3 and tho
springs 3 but upon the "stop rod" being placed in position for starting the loom the
rotation of the crank-pin 5 will cause it to pass against the abutment 3° against
which it will be retained by the springs 3b so that vibratory motion will be imparted
to the frame 1.

A further part of our invention relates to looms in which what are known as
rising or falling shuttle boxes are employed and, consists in a method of operating
the pattern-chain or pattern-cards used for causing or controlling the raising and
lowering of the shuttle boxes and this portion 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 portion of our invention into effect we employ for
causing or controlling the raising and 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. The said pattern-chain may be of any suitable construction.
To operate the pattern-chain as above described we pass such pattern-chain around a
barrel or roller or other suitable means which barrel or roller or other suitable means
we actuate by means of levers or a chain or chains or suitable gearing which are or is
so acted upon by a "governing pattern-chain " of any construction that the lovers,
chain or chains or suitable gearing will cause the barrel or roller or other convenient
means to be turned in one direction or the other or remain stationary as may be
desired.
This part of our invention is illustrated by Figs. 1, 2, 3 and 6 of the accompanying
drawings, mounted fast upon one end of the axle 6 of the chain-barrel 6 is a wheel
8 from one face of which project. pegs 8. Gearing into or engaging with the
D

page_text: wheel 8 is a wheel 10 mounted fast upon a short shaft 9 carried by the frame 1.
Carried by the bracket 6 and free to be rotated therein is a short shaft 21 upon
which is mounted a chain or "lag" barrel 22 around which passes a chain 23
of "lags." Secured to the bracket is a stud 24 and free to be turned thereon are
mounted levers 25, 26 shown more clearly in Figs. 19 and 20. To the lever 25 is
secured an arm 25" which is at times acted upon by the "lags" forming the chain 23.
The lever 25 is provided with a claw 25° which at times acts upon one or other of the
pegs 8° upon the wheel 8.
To the lever 26 is secured an arm 26 which at times is acted upon by the "lags"
forming the chain 23. The lever 26 is formed with a claw 26 which at times acts
upon one or other of the pegs 10 with which the wheel 10 is provided. To the frame 1
we secure a spring 27 which acting against the pegs 8 prevents the barrel 6 from
"over running." The vibration of the frame 1 will cause the pegs 8", 10" of the
wheels 8 and 10 to pass to and fro beneath the levers 25, 26, respectively. The lag
chain 23 is formed of "lags" some provided with projections 23" and lower
portions 23 as shown in Fig. 21 which shows a portion detached and some provided
with raised portions 23 only, as shown in Fig. 22 which shows a portion detached.
The arm 25ª is raised by the raised portion of the lag situate at J while the arm 26ª
is allowed to descend into the position in which it is indicated in Fig. 19 of the
drawing. The descent of the arm 26° will allow the lever 26 to descend so that when
the frame 1 oscillates in the direction opposite to that indicated by the arrow Ę the
wheel 10 will be turned in the direction indicated by the arrow K and cause the
chain-barrel 6 to be turned in the direction indicated by the arrow L and the lever 25
by being in the raised position keeps the claw 25 clear of the pegs 8-So long as
lags
"similar to the one shown in Figs. 19 and 20 as being at J, act upon the
arms 25 the pattern-chain-barrel 6 will be turned in the direction indicated by the
arrow I.
وو
"When
a "lag" so placed in the chain 23 that the projection 23 thereon
may at times act upon the arm 26, arrives at J the claw 26" will be raised clear
of the pegs 10" and the arm 25° being allowed to descend the claw 25 will when the
frame 1.is being oscillated in the direction opposite to that indicated by the arrow E
engage with the pegs 8 and by so doing cause the wheel 8 to be turned in the
direction opposite to that indicated by the arrow L so as to cause the chain barrel 6
to be turned in a direction opposite to that indicated by the arrow L.-By a "lag
provided with a raised portion 23° being brought to J, the claw 26 will be held clear
of the pegs 10 the claw 25 will be held clear of the pegs 8" and no motion will be
imparted to the pattern-chain-barrel 6.
To rotate the lag-barrel 22 we employ the arrangement which we will now
describe.
Passing through and capable of being slidden in holes in the bracket is a needle 28
forced in the direction indicated by the arrow D by a spring one end of which abuts
against the bracket while the other end of such spring abuts against a collar formed
on the needle 28.-To an extended part 28 of the needle 28 is jointed. a claw 29
which at times acts upon the teeth of a ratchet wheel 30 fast on the shaft 21. When
a plate of the pattern-chain 7 having a blank. portion in the part presented to the
needle 28 is caused by the oscillation of the frame 1 to act upon the needle 28 such
needle 28 will be moved in a direction opposite to that indicated by the arrow D and
by causing the claw 29 to move in the same direction will cause the ratchet wheel 30
and barrel 22 to be turned in the direction indicated by the arrow M. When the
frame 1 oscillates in a direction opposite to that indicated by the arrow E the claw 29
will be caused by the spring acting thereon to pass over the teeth of the ratchet
wheel 30 in a direction opposite to that previously described. We mount upon the
shaft 21 a wheel 21ª the circumference of which is formed with flattened portions
against which presses a spring 21 secured to the bracket such spring 21 and the
wheel 21ª preventing the lag barrel 22 from " over running."
We in some cases employ the arrangement shewn in Figs. 23. 24, 25 and 26-for
reversing the motion of the pattern -chain 7. In this arrangement we employ

page_text: levers 35, 36 similar to the levers 25 and 26 shown in and described in reference to
Figs. 19 and 20 but instead of employing them to each operate a wheel provided with
pegs we cause the claws 35, 36 to operate upon the pegs of one wheel. Fast upon
the axle 6 of the pattern-chain-barrel 6 is a wheel 8 provided with pegs Sª. When
the claw 35 is allowed to descend by the arm 35b being unsupported by a portion of
a "lag" of the lag-chain 23 the claw 36 will be clear of the pegs 8" and when the
arın 6 is also unsupported by a "lag" of the lag-chain 23 the claw 35" will also be
allowed to descend and when the frame 1 is moved in the direction opposite to that
indicated by the arrow E the claw 35" acting upon the pegs 8" will cause the wheel 8
to be rotated in the direction opposite to that indicated by the arrow L.
:
When the rotation of the barrel 22 brings a "lag" of the chain 23 provided with a
projecting part such as that shown in Fig. 25 to J the claw 35 will be raised clear of
the pegs 8 and the claw 36" will also be raised so that when the frame 1 is moved in
the direction opposite to that indicated by the arrow E the claw 36° will act upon the
pegs 8 and rotate the wheel S in the direction indicated by the arrow L.
By causing a "lag" of the form shown in Fig. 26 to be brought to J the arm 35
will be supported upon the projecting part of the said "lag" and the claw 35" will be
raised clear of the pegs S. The arın 36 being allowed to descend the claw 36* will
be clear of the pegs 8 so that when the frame 1 is moved in a direction opposite to
that indicated by the arrow E no movement of the wheel 8 and pattern-chain 7 will
take place.
By the above described arrangements by which we actuate or control the movements
of the pattern-chain 7 we are enabled to reverse "the pattern chain 7 on "two picks
of weft or on any multiple of "two picks."
Figs. 27 and 28 show another arrangement which we employ in some cases for
"reversing" the motion of the pattern-chain 7. Upon a stud 31 and free to turn
thereon we mount,an arm 32 to which are jointed levers 33 and 34, the lever 33 being
provided with a claw 33" and the lever 34 being provided with a claw 34. When
the arm 32 is raised by a peg or "lag" of the lag chain 23 the oscillation of the
frame 1 will cause the claw 34° to act upon the pegs 8 so as to cause the pattern-
chain-barrel 6 to be turned in the direction indicated by the arrow L. When the
arm 32 is supported upon a shorter peg or projecting part upon the lag-chain 23. the
arm 32 will descend and allow the claw 33 to act upon the pegs 8ª the oscillation of
the frame thereby causing the pattern-chain-barrel 6 to be reversed" and be
turned in the direction opposite to that indicated by the arrow L.
"
The pivots 33, 34° allow the claws 33" 34" to pass over the pegs 8 when the
frame 1 is being oscillated in the direction indicated by the arrow E. The claw 34ª
is held up by a spring 34°. The claw 33ª is prevented from descending beyond a
certain position by a stop 33°.
