Improvements in Shuttle-box-operating Mechanism for Looms.
We, ALFRED GARTNER, Civil Engineer, and ROBERT ATHERTON, Mechanical
Engineer, both of 152 Market Street, City of Paterson, County of Passaic and
State of New Jersey, U.S.A., do hereby declare the nature of this invention to
be as follows:-
The object of our invention is to provide a shuttle box operating mechanism for
looms, of simple, strong and durable construction, reliable in operation and not
liable to get out of order.
The invention consists in the improved shuttle box operating mechanism, its
lifting levers controlling "cam- groove wheels"; in the means for operating and
controlling the said "cam-groove wheels," and in the combination and arrangement
of the various parts thereof, substantially as will be hereinafter more fully
described.
Referring to the accompanying drawings, in which like letters of reference
indicate corresponding parts in each of the several views:

Figs. 9 and 10 are enlarged detail views of the pattern chain operating
mechanism as shown in Fig. 1; and
Fig. 11 a detail view of the preferred form of said pattern chain operating
mechanism.
In said drawings a represents the loom frame, in which is arranged the shaft c
transmitting its motion through crank cl and pitman e' to the lay or batten e supported
oy swords d, the latter fulcrumed as at d 1 to the loom frame. At each end of the
ay are arranged the shuttle boxes f carried by rods 1, each of which rods is
guided by the block d2 secured to the lay-sword, and is surrounded by a spiral
pring f3, bearing with one end on said block d 2 and with its other end on the
ut or collar 15 secured at or near the lower end of the rod f1,-all said parts of
he usual well known construction.
On the shafte (see Figs. 1, 9 and 10) is splined by means of a feather j 12 a
rooved collar; 11 carrying the radial arms j4 (arranged diametrically opposite

page_text: each other), and provided at or near the outer ends with wheels or rollers ; 10,
adapted to engage the curved portion 3 of angle lever; and thus to operate the
same. The annular groove of the collar j11 is engaged by the forked portion of
the fulcrumed angle lever j5, which latter is operated through cord j 6 from the
Jacquard machine in the ordinary manner.
The shaft c is surrounded by a spiral spring; 14 bearing with one end on the
grooved collar 11 and with its other end on a collar; 13 firmly secured to the
shaft c. The spring being compressed, angle lever j 5, on being released, will force
the collar 11 outwards on shaft c and thus the rollers j 10 out of the path of the
angle lever j.
The said lever is fulcrumed as at jl to the loom frame, and is controlled by a
spring 2. To the free end of the shorter arm of said augle lever is pivotally
secured a spring controlled pawl, adapted to engage the teeth of the ratchet
wheel a 5 and thus to operate the same. The ratchet wheel a 5 is mounted on
shaft a 2 supported by frame a and also by a bracket frame a 0. On said shaft is
firmly secured the sprocket wheel a 4 carrying the pattern chain, and adapted to
operate the levers h, 1. ..., pivoted with one end to a stub shaft a 3 and
provided at their other ends with cords or wires i, il (i2 and 3), which latter are
connected with the shuttle box operating mechanism as will be hereinafter more
fully described.
To the bracket frame a 0 is also secured edgeways a flat but curved spring a 11
adapted to rest with its curved portion between adjoining rollers of the pattern
chain, and thus to hold the said pattern chain and its sprocket wheel in position,
whenever the shaft a 2 has been turned the required distance by means of the
ratchet wheel a 5 and its operating pawl.
On the shaft b, which has its bearings in the loom frame and which receives its
revolving motion from driving shaft c-(through a train of gear wheels arranged on
the opposite side of the loom, as in the ordinary manner, and which therefore is not
illustrated in the drawings), is secured the wheel or disc 1 provided at the inner
side of its rim with four headed pins o arranged horizontally and diametrically
opposite each other; and having an enlarged portion o 20 as clearly shown in
Figs. 4, 5, 6 and 64, each pin is surrounded and thus controlled by a spiral
spring o8 and rests when in normal position with its enlarged portion in a hole
penetrating the rim of the wheel b1, but does not (when in said normal position)
project beyond the outer face of said rim, see Figs. 4 and 5.
Said pins o are adapted to be operated, that is to say, pressed outwards beyond
the outer face of the rim of wheel 61 by levers o 1, each of which is controlled
by a spring o 10, and is pivoted as at o 2 to a bracket of the circular frame o 3,
arranged in rear of the wheel 61 and parallel therewith and secured to the loom
frame by bolts or in any desired manner.
There are four levers o 1 pivoted to their respective brackets and are arranged
diametrically opposite each other. Each of said levers is segmental shaped as
clearly shown in Fig. 3 and thus covers the path of the pins o when the wheel 61
is rotated. The free end of each lever which is curved as at o 7, is engaged by
one arm o 12 of angle lever o 5, pivoted to a bracket o 4 of the circular frame o 3,
and controlled by a spiral spring o11 secured with one end to the frame o 3 in
any desired manner and with its other end to the other arm o 15 of the angle
lever o 5.
The outer ends of said arms 15 of the angle levers are connected to and
thus. operated by their respective cords or wires il (i1, i2 and i 3), as will be
hereinafter more fully described.
The arm o 12 is hinged as at o 14 to said angle lever and is controlled by a flat
spring o 13, as clearly shown in Figs. 7 and 8. Said arm 12 is adapted to be
thrown out of the path of the curved end o7 of lever ol by means of the
pins o6, which latter are firmly secured to the inner side of the rim of the
wheel 1 and a short distance away from the radial lines of the pins o, see
Fios 345 and 6

page_text: The length of the pins 06 is such that they will only engage the hinged
portion o 12 of the angle lever, when the latter has been operated by its respective
cord and thus has operated the lever o 1. When the hinged portion o 12, against
the action of its flat spring o 13-has been forced outwards by the pin o6 it will
bear against the curved end of the lever o 1, which by that time has returned by
action of spring o 10 to its normal position, (see Fig. 6).
In the frame a are journaled the shafts a 6, a 7, a 8 and a 9, which are arranged
diametrically opposite each other and about opposite the centers of the levers o 1.
On each of these shafts is secured a wheel 2, b3, b4 and 65 respectively provided
at its outer periphery and at regular intervals with a series of eight notches m with
flaring mouth m 1 adapted to be engaged by the pins o of the wheel 6 1, (when
said pins are operated), and thus to be rotated one-eighth of a revolution.
On the outer face of each shaft a 6 (a 7, a 8 and a 9) is arranged an endless cam-
groove consisting of four concave and four convex curves m 3 and m 2, arranged
alternately and in such a manner on the wheel, that the culminating point of each
curve is on a radius midway between each two adjoining notches.
In each endless cam groove is arranged and adapted to be operated thereby a
pin g 10, 11, 12 and g 13 respectively, guided by the vertically arranged slots of
the brackets n, secured to the circular frame o 3 or to the loom frame a in any
desired manner, only two of said slotted brackets being shown in the drawings,
see Fig. 3.
The pin g 11 is firmly secured to the lever g, whilst the pin g 10 is adapted to
operate in the elongated slot g 9 arranged in the free end of said lever g, the other
end of which is connected by the link f4 with the collar f5 on the shuttle box
supporting rod f1.
The pins g 13 and 9 12 are likewise arranged in lever g 1, which is adapted to
operate through crank g 2-the shaft 93. To the opposite end of said shaft is
secured the lever g4 (shown in dotted lines in Fig. 1) and which lever through a
connection similar to link f4, operates the shuttle box. supporting rod on
opposite end of the loom.
the
The pins g 10, g 11, g 12 and g 13 may, if desired be surrounded by a small
cylindrical sleeve to reduce the friction during the operation.
To each bracket n is also secured in any desired manner a spring n 1 carrying at
its free end a brake block n 2 adapted to rest in the notches m of its respective
wheel, when the same has been rotated the required distance that is to say,
one-eighth of a revolution.
The operation of the device is as follows: reference being made to Figs. 1 to 8
inclusive of the drawings. During the operation of plain weaving, the shuttle box
operating mechanism is at rest as the collar j11 with its arm j4 and rollers ; 10
has, by action of the spiral spring j 14, been forced out of the path of pawl carrying
lever Fig. 10. and the sprocket wheel a 4 carrying the pattern chain is thus
prevented from being rotated. When the jacquard calls for the introduction of
a color to be worked in a figure or design of the fabric, the cord j6 is drawn
upwards (by the jack or hook of the machine) and through the angle lever j5
engaging the annular groove of collar j11, the said collar and its arms j4 and
rollers 10 are moved into the path of lever j. One of the rollers j 10 (as the
collar 11 is continually revolving with shaft c) will strike the curved portion 3
of pivoted angle lever; and thus operate the said angle lever and through its
pivoted pawl, engaging the teeth of ratchet wheel a 5, will rotate the shaft a 2 the
required distance (in the drawings one-eighth of a revolution). The sprocket
wheel a 4 is thus revolved, operating the pattern chaiu until one of its rollers comes
under and lifts one of the levers h, h 1.
In Fig. 1 of the drawings is illustrated the position of lever g, when the first
compartiment of the shuttle box (from the top) is brought opposite the lay or race
and ready to discharge its shuttle.
Supposing that the second shuttle (from the top-see also the upper portion of
diagrammatic view of Fig. 2)-is called for, after the first shuttle has performed

page_text: its operation; the lever 1 is raised by its respective roller of the pattern chain,
thus lifting through its cord connection the angle lever o 5 (corresponding with cam
groove wheel 2) and the latter in turn depressing the lever o 1.
The spring controlled headed pin o carried along by the wheel 1 (revolving in
the direction of arrow Q, Fig. 3) is, as soon as it reaches the said depressed
lever o 1, engaged by the same and forced outwards beyond the outer face of the
rim of said wheel b1, and into the notch m of cam groove wheel 62. The said
wheel is thus rotated one-eighth of a revolution, and the guided pin g 10, engaged
by the cam groove on wheel 62 is moved downwards, until it rests in the culminating
point of the concave curve m 2. The pin g 11 has acted as fulcrum and the lever
will thus occupy the position marked "2" in the upper half of Fig. 2.
Soon after the pin o has left the notch m of wheel 2, its co-operative pin o 6
engages the hinged portion o 12 of angle lever o 5 and forces the same out of the
path of lever ol which latter by the action of the spiral spring o 10 is returned to
its normal position; the hinged portion o 12 of angle lever o 5 bearing on the
curved end o 7 of lever o 1 (see Fig. 6). This is a very important point, as for
instance, should the pick be repeated (the sprocket wheel and the pattern chain
being prevented from rotation, the cord 6 being released by the Jacquard machine
and thus the rollers j 10 moved out of the path of angle lever j, as heretofore
described), the wheel 62 must remain unmoved, that is to say, the next following
spring controlled headed pin o must pass under the lever o 1 without being operated,
and this can only be accomplished by having the lever o1 returned to its normal
position, notwithstanding, that its respective angle lever remains in operative
position. As soon as the strain on the angle lever is released, that is to say-its
respective treadle lever h1 is lowered, said angle lever by the action of the
spring o11 is returned to its normal position, and rests again with its hinged
portion o12 on the top surface of the curved end of the lever o 1, (the hinged..
portion being returned to its normal position by the action of the flat spring o 12).
If for instance, the fourth shuttle (from the top) is required-the sprocket wheel
and pattern chain being again brought in operation by the Jacquard machine-the
pin g 10 must be lowered and the pin 911 raised. For that purpose the two
levers h, 1 corresponding with the wheels 63 and 62 are raised by the rollers on the
pattern chain, and the respective angle levers o5 are thus operated and the levers o 1
controlling the pins o thereby depressed. The wheels 63 and 62 are each turned
by their respective pins o one-eighth of a revolution and the lever g thus brought
into the position marked 1 V in the upper half of the diagrammatic view in Fig. 2.
The mode of operation of the lower cam groove wheels 64 and 65 and the
connecting lever g1 is the same as that of the upper series, except that they are
operated through cords 2 and 3 connected to a second set of treadle levers
similar to the levers h and h 1.
The lever g1 operates through crank g 2, shaft g3 and lever g4 the shuttle box
supporting rod on the opposite side of the loom..
In Fig. 11 of the drawings I have illustrated a modified form of device for
operating the sprocket wheel a 5 on shaft a 2.
On the shaft c is firmly secured a gear wheel r 1 meshing with a gear wheel + 2
on shaft r 3. Said gear wheel. r2 is one-half the diameter of the gear wheel rl.
On shaft 3 is also arranged an eccentric r4 provided with an arın r5 having
a pawl shaped end and on its underside a cam r6 and being controlled by a spiral
spring 7. Pivoted to the loom frame as at r9 is the angle lever r8 controlled
by spring r10 and connected with one arm through cord j6 with the Jacquard
mechanism. The other arm of said angle lever r8 is provided with a roller rll
adapted to bear on the underside of the arm r5, which latter with its pawl
shaped end engages the teeth of the sprocket wheel a 5. During the operation
of plain weaving, the cord j6 is lowered and the angle lever r8 by the action of
the spring 10 is brought under the cam r6 of arm, thus raising the arm out.
of engagement with the teeth of the sprocket wheel a 5 and thus preventing the
shaft a 2 from being rotated. As soon as the cord j6 is drawn upwards, the angle.

page_text: is returned to its normal position and the pawl shaped end of arm 5
again thrown into engagement with the teeth of the sprocket wheel as will be
manifest.

Te-box-operating Mechanism for Looms.
We, ALFRED GARTNER, of 152 Market Street, City of Paterson, County of
O Passaic, State of New Jersey, U.S.A., Civil Engineer, and ROBERT ATHERTON
of 152 Market Street in the City of Paterson, County of Passaic and both in the
State of New Jersey, U.S.A., Machinist, 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 :-
5
The object of our invention is to provide a shuttle-box-operating mechanism for
looms of simple, strong and durable construction, reliable in operation and not
liable to get out of order.
The invention consists in the improved shuttle-box-operating mechanism, its
lifting-levers controlling "cam-groove wheels," in the means for operating and
controlling the said cam-groove wheels, and in the combination and arrangement
of the various parts thereof, substantially as will be hereinafter more fully described,
and finally embodied in the clauses of the claim.
Referring to the drawings filed with the Provisional Specification, in which like
letters of reference indicate corresponding parts in each of the several views,
Figure 1 is a side elevation of a loom provided with our inprovements only
those parts of the loom and of the said improvements being shown which are
necessary to fully illustrate the nature of our invention.

operating mechanism in two successive working positions;
Figs. 7 and 8, enlarged detail views of a certain operating angle-lever, hereinafter
more fully described.
Figs. 9 and 10 are enlarged detail views of the pattern-chain-operating
mechanism, as shown in Fig. 1; and
Fig. 11, a detail view of the preferred form of said pattern-chain-operating
mechanism.
In said drawings, a represents the loom-frame, in which is arranged the driving-
shaft c, transmitting its motion through crank cl and pitman c2 to the lay or
batten e, supported by swords d, the latter fulcrumed, as at d 1, to the loom-frame.
At each end of the lay are arranged the shuttle-boxes f, carried by rods f1, each
f which rods is guided by the block d 2 secured to the lay-sword and is surrounded
y a spiral spring f3, bearing with one end on said block d2 and with its other

page_text: end on the nut or collar f5 secured at or near the lower end of the rod f1, all said
parts of the usual well-known construction.
On the shaft c (see Figs. 1, 9 and 10) is splined, by means of a feather 12, a
grooved collar j11, carrying the two radial arms j4, arranged diametrically
opposite each other and provided at or near the outer ends with wheels or rollers j 10,
adapted to engage the curved portion j3 of angle-lever j, and thus to operate the
same. The annular groove of the collar j11 is engaged by the forked portion
of the fulcrumed angle-lever j5, which latter is operated through cord j6 from
the Jacquard machine in the ordinary manner.
The shaft c is surrounded by a spiral spring j14, bearing with one end on the
grooved collar j11 and with its other end on a collar 13 firmly secured to the
shaft c.
The spring being compressed, angle-lever j5, on being released, will
force the collar 11 outward on shaft e and thus the rollers i 10 out of the path
of the angle-lever The said lever j is fulcrumed, as at 1, to the loom-frame
on the by
angle-lever is pivotally secured a spring-controlled pawl j 30, adapted to engage
the teeth of the ratchet wheel a 5 and thus to operate the same. The ratchet
wheel a 5 is mounted on shaft a 2, supported by frame a and also by a bracket-
frame a 0. On said shaft is firmly secured the sprocket-wheel a 4, carrying the
pattern-chain and adapted to operate the levers h h 1, pivoted with one end to a
stub-shaft a 3, and provided at their other ends with cords or wires i, il i2 and 3,
which latter are conuected with the shuttle-box-operating mechanism, as will be
hereinafter more fully described. To the bracket-frame a 0 is also secured edgewise
a flat but curved spring a 11, adapted to rest with its curved portion between
adjoining rollers of the pattern-chain, and thus to hold the said pattern-chain and
its sprocket-wheel in position whenever the shaft a 2 has been turned the required
distance by means of the ratchet-wheel a 5 and its operating-pawl.
On the shaft b, which bas its bearings in the loom-frame and which receives
its revolving motion from driving-shaft c, (through a train of gear-wheels arranged
on the opposite side of the loom, as in the ordinary manner, and which therefore
is not illustrated in the drawings,) is secured the wheel or disk 61, provided at
the inner side of its rim with four headed pins o, arranged horizontally and
diametrically opposite each other and having an enlarged portion o 20, as clearly
shown in Figs. 4, 5, 6 and 64. Each pin is surrounded and thus controlled by a
spiral spring o8 and rests when in normal position with its enlarged portion in a
hole penetrating the rim of the wheel b1, but does not, when in said normal
position, project beyond the outer face of said rim. (See Figs. 4 and 5.). Said
pins o are adapted to be operated-that is to say, pressed outward beyond the
outer face of the rim of wheel 61-by levers o 1, each of which is controlled by a
spring o 10 and is pivoted, as at o 2, to a bracket of the circular frame o 3, arranged
in rear of the wheel 61 and parallel therewith and secured to the loom-frame by
bolts or in any desired manner.
There are four levers o1 pivoted to their respective brackets and arranged
diametrically opposite each other. Each of said levers is segment-shaped, as
clearly shown in Fig. 3, and thus covers the path of the pins o when the wheel 61
is rotated. The free end of each lever, which is curved, as at o7, is engaged by
one arm o 12, of angle-lever o 5, pivoted to a bracket o 4 of the circular frame o 3
and controlled by a spiral spring o11 secured with one end to the frame o 3 in any
desired manner and with its other end to the other arm, o 15, of the angle-lever o 5.
The outer ends of said arms o 15 of the angle-levers are connected to and thus
operated by their respective cords or wires i, il, i2 and i3, as will be hereinafter
more fully described.
The arm o 12 is hinged, as at o 14, to said angle-lever and is controlled by a flat
spring o 13, as clearly shown in Figs. 7 and 8. Said arm o 12 is adapted to be
thrown out of the path of the curved end o 7 of lever o 1 by means of the pins o 6,
which latter are firmly secured to the inner side of the rim of the wheel 61 and a
short distance away from the radial lines of the pins o. (See Figs. 3, 4, 5 and 6.)

page_text: The length of the pins o6 is such that they will only engage the hinged
ortion o 12 of the angle-lever when the latter has been operated by its respective

ord and thus has operated the lever o 1.
he action of its flat spring o 13, has been forced outward by the pin o 6, it will bear
gainst the curved end of lever o 1, which by that time has returned by action of
pring o 10 to its normal position. (See Fig. 6A.)
In the frame a are journaled the shafts a 6, a 7, a 8 and a 9, which are arranged
liametrically opposite each other and about opposite the middle of the levers o 1.
On each of these shafts is secured a wheel 62, 63, 4 and 5, respectively,
provided at its outer periphery and at regular intervals with a series of eight
hotches m with flaring mouths m 1, adapted to be engaged by the pins o of the
wheel 61, (when said pins are operated), and thus to be rotated one-eighth of a
revolution.
On the outer face of each wheel a 6, a 7, a 8 and a 9 is arranged an endless
cam-groove consisting of four concave and four convex curves m 3 and m 2, arranged
manner on the wheel that the
alternately and symmetrically and in such a
culminating point of each curve is on a radius midway between each two adjoining
notches.
In each endless cam-groove is arranged and adapted to be operated thereby a
pin g 10, g 11, g 12 and g 13, respectively, guided by the vertically-arranged slots
of the brackets n, secured to the circular frame o 3 or to the loom-frame a in any
desired manner, only two of said slotted brackets being shown in the drawings.
(See Fig. 3.) The pin g 11 is firmly secured to the lever g, while the pin g 10 is
adapted to operate in the elongated slot g 9 arranged in the free end of said lever g,
the other end of which is connected by the link f4 with the collar 2 on the
shuttle-box-supporting rod fl. The pins g 13 and 9 12 are likewise arranged in
lever g 1, which is adapted to operate, through shaft g 2, the shaft g 3. To the
opposite end of said shaft is secured the lever g 4, (shown in dotted lines in Fig. 1,)
and which lever through a connection similar to link f4 operates the shuttle-box-
supporting rod on the opposite end of the loom:
The pins g 10, 11, 12 and g 13 may, if desired, be surrounded by a small
cylindrical sleeve to reduce the friction during the operation.
To each bracket n is also secured in any desired manner a spring nl, carrying at
its free end a brake-block n 2, adapted to rest in the notches m of its respective
wheel when the same has been rotated the required distance that is to say, one-
eighth of a revolution.
The operation of the device is as follows, reference being made to Figs. 1 to 10,
inclusive, of the drawings: During the operation of plain weaving the shuttle-
box-operating mechanism is at rest, as the collar 11 with its arm j4 and
rollers 10 has, by action of the spiral spring j 14, been forced out of the path of
pawl-carrying lever j, Fig. 10, and the sprocket-wheel a 4 carrying the pattern-
chain is thus prevented from being rotated. When the jacquard calls for the
introduction of a color to be worked in a figure or design of the fabric, the cord j6
is drawn upward by the jack or hook of the machine, and through the angle-
lever j5 engaging the annular groove of collar j11 the said collar and its arms j4
and rollers 10 are moved into the path of lever j. One of the rollers 10 (as
the collar 11 is continually revolving with shaft c) will strike the curved portion 3
of pivoted angle-lever j and thus operate the said angle-lever, and through its
pivoted pawl 30, engaging the teeth of ratchet-wheel a 5, will rotate the shaft a 2
the required distance, (in the drawings one-eighth of a revolution). The sprocket-
wheel a 4 is thus revolved, operating the pattern-chain until one of its rollers
comes under and lifts one of the levers h'hl. In Fig. 1 of the drawings is
illustrated the position of lever g when the first compartment of the shuttle-box
(from the top) is brought opposite the lay or race and ready to discharge its
shuttle. Supposing that the second shuttle from the top (see also the upper
portion of diagrammatic view of Fig. 2) is called for after the first shuttle has
performed its operation, the lever 1 is raised by its respective roller of the

page_text: pattern-chain, thus lifting through its cord connection the angle-lever o5
(corresponding with cam-groove wheel 2) and the latter in turn depressing the
lever 1. The spring controlled headed pin o carried along by the wheel 61
(revolving in the direction of arrow Q, Fig. 3) is, as soon as it reaches the
said depressed lever o 1, engaged by the same and forced outward beyond the
outer face of the rim of said wheel b1 and into the notch m of cam-groove
wheel 62. The said wheel is thus rotated one-eighth of a revolution, and the
guided ping 10, engaged the cam-groove on wheel 62, is moved downward until
it rests in the culminating point of the concave curve m2. The pin 11 has acted
as fulcrum and the lever will thus occupy the position marked "II" in the upper
half of. Fig. 2. Soon after the pin o has left the notch m of wheel 2 its
co-operative pin o6 engages the hinged portion o 12 of angle-lever o 5 and forces
the same out of the path of lever o 1, which latter by the action of the spiral
spring o 10 is returned to its normal position, the hinged portion o 12 of angle-
lever o 5 bearing on the curved end o7 of lever o1. (See Fig. 6.) This is a
very important point-as, for instance, should the pick be repeated, the sprocket-
wheel and the pattern-chain being prevented from rotation, the cord 16 being
released by the Jacquard machine and thus the rollers j 10 moved out of the path
of angle-lever j, as heretofore described, the wheel 62 must remain unmoved-that
is to say, the next following spring-controlled headed pin o must pass under the
lever o 1 without being operated, and this can only be accomplished by having the
lever o1 returned to its normal position, notwithstanding that its respective angle-
lever remains in operative position. As soon as the strain on the angle-lever
is released--that is to say, its respective treadle-lever 1 is lowered-said angle-
lever by the action of the spring'o 11 is returned to its normal position and rests
again within its hinged portion o12 on the top surface of the curved end of the
lever o 1, (the hinged portion being returned to its normal position by the action of
the flat spring o 13). If, for instance, the fourth shuttle (from the top) is required,
the sprocket-wheel and pattern-chain being again brought in operation by the
Jacquard machine, the pin g 10 must be lowered and the pin g 11 raised. For that
purpose the two levers h h1 corresponding with the wheels 3 and 62 are raised
by the rollers on the pattern-chain, and the respective angle-levers 05 are thus
operated and the levers ol controlling the pins o thereby depressed.. The wheels b3
and 62 are each turned by their respective pins o one-eighth of a revolution, and
the lever g thus brought into the position marked "IV" in the upper half of the
diagrammatic view in Fig. 2.
The mode of operation of the lower cam-groove wheels 4 and 65 and the
connecting-lever al is the same as that of the upper series, except that they
are operated through cords i2 and i3, connected to a second set of treadle-levers
similar to the levers hand h 1. The lever g 1 operates, through crank g 2, shaft g 3,
and lever g 4, the shuttle-box-supporting rod on the opposite side of the loom.
In Fig. 11 of the drawings we have illustrated a modified form of device for
operating the sprocket-wheel a 5 on shaft a 2.
On the shaft c, Fig. 11, is firmly secured a gear-wheel r 1 meshing with a gear-
wheel 2 on shaft r3. Said gear-wheel r2 is one-half the diameter of the gear-
wheel r1. On shaft r3 is also arranged an eccentric r 4, provided with an arm r5,
having a pawl-shaped end and on its under side a cam r6 and being controlled by
a spiral spring 7. Pivoted to the loom-frame, as at 9, is the angle-lever r8,
controlled by spring r 10 and connected with one arm through cord j6 with the
Jacquard mechanism. The other arm of said angle-lever r8 is provided with a
roller 11 adapted to bear on the under side of the arm r.5, which latter with its
pawl-shaped end engages the teeth of the sprocket-wheel a 5. During the opera-
tion of plain weaving the cord j6 is lowered and the angle-lever r8, by the action
of the spring r 10, is brought under the cam r6 of arm r5, thus raising the arm
out of engagement with the teeth of the sprocket-wheel a 5 and thus preventing
the shaft a 2 from being rotated. As soon as the cord j6 is drawn upward the
angle-lever r8 returned to its normal position and the pawl-shaped end of

page_text: arm 5 again thrown into engagement with the teeth of the sprocket-wheel, as
will be manifest.
