and Falling, Revolving, or other Movable 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 portions of improvements for which Letters Patent No. 6209 dated
April 26th 1888, and No. 3544 dated February 28th 1889 were granted to us
James Cowburn and Christopher Peck. The arrangements described in the
Specifications filed in respect of the applications for the Letters Patent above
referred to were only applicable to looms, in which not more than four rising or
falling shuttle boxes were employed but our present invention is applicable to
looms having two, three, four, five, six, seven, or eight rising or falling, revolving
or other movable shuttle-boxes.
According to our present invention we employ three discs or plates. One of
the said discs or plates is provided with a boss and is carried by and capable of
being at times turned upon a stud secured to a framing secured to the framework
of the loom. Projecting from the boss above mentioned is a stud or pin placed
excentric to the axis of the aforesaid boss. The stud or pin aforesaid projects
into a hole formed in an arm provided with a projecting pin or stud which
projects into a slot formed in a disc mounted and capable of being turned upon
the boss of the disc before referred to.
In the arm before referred to is formed a hole into which projects a pin
projecting from an arm provided with a pin which is embraced by one end of a
connecting rod which at its other end is connected to a lever connected by means
of a rod or any other suitable means to the rising or falling revolving or other.
movable shuttle boxes. The pin aforesaid after passing through the connecting
rod projects into a slot formed in a disc carried upon a stud capable of being
turned in a bracket secured to the frame above referred to. Each of the discs
above mentioned is provided with a toothed wheel. We also employ three toothed
racks to which we impart a longitudinal reciprocating motion. The racks above
mentioned are by means of a suitable pattern chain and darts or needles caused
at times to pass independently or together into gear with the wheels above
mentioned.
The barrel by which the pattern chain above mentioned is rotated we mount
upon a frame which we cause to oscillate. When a certain part of the pattern
chain is caused to act upon one or more of the darts or needles above mentioned
one or more of the racks will cause one or more of the discs to be rotated one
half of a revolution. Such rotation of one or more of the discs before mentioned
will cause the pin passing through the connecting rod to be raised or lowered in
reference to its previous position thereby bringing one or other of the shuttle
boxes into the position desired. After the disc or discs has or have been turned
into the required position they are retained in position by means of a detent or
catch, until another change is to take place.
When applying our above described invention to looms having revolving or
rotary shuttle boxes we rotate such shuttle boxes by means of a toothed rack and
pinion or toothed racks and pinions such toothed rack and pinion or toothed racks
and pinions being held in gear by means of a spring or springs, the spring or

page_text: springs yielding in case an obstruction occurs to the rotation of the boxes thereby
preventing breakage or injury of parts from occurring.
By our invention we are able to change from any box to any other box.

Improvements connected with Apparatus for Operating the Rising
and Falling, Revolving, or other Movable 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 manner 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 portions of improvements for which Letters Patent No. 6209 dated
April 26th 1888 and No. 3544 dated February 28th 1889 were granted to us
James Cowburn and Christopher Peck. The arrangements described in the
Specifications filed in respect of the applications for the Letters Patent above
referred to were only applicable to looms, in which not more than four rising or
falling shuttle boxes were employed but our present invention is applicable to
looms having two, three, four, five, six, seven or eight rising or falling, revolving
or other movable shuttle-boxes.
According to our present invention we employ three discs or plates. One of
the said discs or plates is provided with a boss and is carried by and capable of
being at times turned upon a stud secured to a framing secured to the framework
of the loom. Projecting from the boss above mentioned is a stud or pin placed
excentric to the axis of the aforesaid boss. The stud or pin aforesaid projects
into a hole formed in an arm provided with a projecting pin or stud which projects
into a slot formed in a disc mounted and capable of being turned upon the boss of
the disc before referred to.
In the arm before referred to is formed a hole into which projects a pin
projecting from an arm provided with a pin which is embraced by one end of a
connecting rod which at its other end is connected to a lever connected by means
of a rod or any other suitable means to the rising or falling revolving or other
movable shuttle-boxes. The pin aforesaid after passing through the connecting
rod projects into a slot formed in a disc carried upon a stud capable of being
turned in a bracket secured to the frame above referred to. Each of the discs
above mentioned is provided with a toothed wheel. We also employ three toothed
racks to which we impart a longitudinal reciprocating motion. The racks above
mentioned are by means of a suitable pattern chain and darts or needles caused
at times to pass independently or together into gear with the wheels above
mentioned.
The barrel by which the pattern chain above mentioned is rotated we mount
upon a frame which we cause to oscillate. When a certain part of the pattern
chain is caused to act upon one or more of the darts or needles above mentioned
one or more of the racks will cause one or more of the discs to be rotated one
half of a revolution. Such rotation of one or more of the discs before mentioned
will cause the pin passing through the connecting rod to be raised or lowered
in reference to its previous position thereby bringing one or other of the shuttle-
boxes into the position desired. After the disc or discs has or have been turned
into the required position it is or they are retained in position by means of a detent
or catch until another change is to take place.

45 is the end frame of the loom to which is secured a frame 46.
According to our invention we employ three discs or plates 47, 48, 49. The
disc or plate 47 is provided with a boss 47" and carried by and capable of being
at times turned upon a stud 50 secured to a bracket secured to the frame 46.
Projecting from the boss 47 is a stud or pin 51 placed excentric to the axis of
the boss 47. The stud or pin 51 projects into a hole formed in an arm 52
provided with a projecting pin or stud 53 which projects into a slot 54 formed in
the disc 48 which is mounted and capable of being turned upon the boss 47° of the
disc 47.
In the arm 52 is formed a hole into which projects a pin 55 projecting from an
arm 55 provided with a pin 56 which is embraced by a connecting rod 57 which at
its other end is connected to one end of a lever 58 mounted and capable of being
turned upon a stud 59 secured to a bracket secured to the end frame 45 of the loom.
The end of the pin 56 projects into a slot 49 formed in the disc 49 which is
provided with a stud 49 carried by and capable of being rotated in a bracket
secured to the frame 46. The discs 47, 48, 49 are provided with toothed
wheels 47, 48, 49° respectively. Carried by the frame 46 is a rod 60 mounted fast
upon which is a boss 61 from which project arms 62, 64. Projecting from the
arm 62 is a stud 62ª which is embraced by one end of a connecting rod 65 the other
end of which connecting rod 65 embraces a stud 66 projecting from an arm secured
upon the tappet shaft 67. Projecting from the arin 62 is a stud 68 upon which
is mounted a rack 69 the teeth of which at times gear with the teeth of the
toothed wheel 47°. Also mounted upon the stud 68 is a toothed rack 70 the teeth
of which at times gear with the toothed wheel 48°. Projecting from the arm 64 is
a stud 71 upon which is mounted a toothed rack 72 the teeth of which at times gear
with the toothed wheel 49°. To the lever 58 is jointed one end of a con-
necting rod 73 the other end of which is connected to the rising and falling
shuttle-boxes 74. To counterbalance the weight of the shuttle boxes 74 and parts
connected thereto we employ a spring 75 connected at its upper end to the
box frame and at its lower end to the lower part of the connecting rod 73.
provide the rods 73 and 57 with springs 73ª and 57ª respectively which
springs 73 57 will yield and prevent injury or breakage if the shuttle boxes 74
should be prevented from rising or falling.
We
Supported by and capable of being slidden through cross bars 46 formed upon
the frame 46 are three darts 76, 77, 78. The end 76 of the dart 76 is situate
behind the toothed rack 69. The end 77* of the dart 77 is situate behind the

page_text: toothed rack 70. The end 78" of the dart 78 is situate behind the toothed
rack 72.
Carried by the frame 46 is a rod 79 mounted upon which and capable of being
oscillated thereon is a frame 80. Carried by the upper part of the frame 80 and
capable of being rotated therein is a pattern chain barrel 81. Formed upon the
frame 80 is an arm 80" projecting from which is a stud 80° upon which is mounted
a bowl 80 against which acts a cam 82 fast upon the tappet shaft 67. 83 is a
spring secured at one end to the end frame 45. The other end of the spring 83 is
secured to the arm 80%. The spring 83 tends to turn the arm 80 in the direction
indicated by the arrow R and keep the periphery of the bowl 80° in contact with
the periphery of the cam 82. Carried by and capable of being oscillated in the
frame 46 is a spindle 84 fast upon which is an arm 85 in which is formed a
slot into which passes a stud 86 projecting from an arm 87, fast upon a boss 60".
Projecting from a part 85° secured to the arm 85 are studs 88, 89. The stud 88 at
times passes into recesses formed in a notched wheel 90 fast upon the axle of the
pattern-chain-barrel 81 so as to turn such pattern-chain-barrel 81 in the direction
indicated by the arrow S. Secured to a bracket 91ª secured to the frame 80 is a
stud 91 upon which is mounted a notched wheel 92, secured to which is a toothed
wheel 93 which gears into a toothed wheel 94 fast with the notched wheel 90.
The stud 89 at times is caused to pass into the recesses formed in the notched
wheel 92.
Secured to the frame 46 is a stud 95 upon which and free to be turned thereon is
mounted the reversing chain barrel 96. 97 is a toothed wheel into which a rack 98
is caused to gear at times. Carried by and capable of being slidden longitudinally
in the cross bars 46", of the frame 46 is a dart 99. One end of the dart 99
is situate so as at times to be acted upon by a portion of the pattern chain 100
passing around the pattern-chain-barrel 8i. Projecting from the dart 99 is
a pin 99" which is situate behind the toothed rack 98 which is mounted upon a stud
projecting from the arm 62 projecting from the boss 61. The toothed rack 98 at
times is by the movement of the pattern-chain 100 caused to gear with the
wheel 97 fast with the lag-barrel 96 around which passes the reversing chain 101.
Carried by and free to be turned upon a stud 102 secured to the frame 46 is
a bell-crank-lever 103. One end of the bell-crank-lever 103 is provided with
a finger 104 which rests upon the lags of the reversing chain 101. The other arm
of the bell-crank-lever is providel with a pin 105 which passes into a jaw 106 upon
a boss secured upon the spindle 84. When the loom is at work the rotation of the
tappet shaft 67 will by means of the arm thereon and the stud 66, con-
necting rod 65 and arm 62 cause the boss 61 with its arm or lever 64 to be
oscillated upon the rod 60 thereby causing the toothed racks 69, 70, 72, 73 to be
raised and lowered.
The rotation of the cam 82 will by means of the bowl 80° and arm 80° cause the
frame 80 and pattern-chain-barrel 81 to be oscillated upon the rod 79 in the
direction indicated by the arrow T. The rotation of the cam 82 will also allow
the frame 80 and pattern chain barrel 81 to be oscillated upon the rod 79 in a
direction opposite to that indicated by the arrow T by the spring 83. Around the
pattern-chain-barrel 81 is passed a pattern-chain 100 formed of plates such as are
shown in Figs. 7, 8, 9, 10, 11, 12, 13, 14, 15. When the pattern-chain-barrel 81 is
being oscillated in the direction indicated by the arrow T and a plate of the
pattern-chain 100 similar to the plate shown in Fig. 14 is presented to the
darts 76, 77, 78 the openings in such plate passing over the ends of the said darts
will not act upon them. When a plate of the pattern chain 100 similar to the plate
shown in Fig. 9 is presented to the darts 76, 77, 78 the dart 76 will by the
oscillation of the frame 80 in the direction indicated by the arrow T be carried
forward in the direction indicated by the arrow T and will by the end 76° of the
said dart 76 acting against the toothed rack 69 turn the toothed rack 69 upon the
stud 68 and cause the rack 69 to pass into gear with the wheel 47°. The toothed

page_text: racks 69, 70, 72 are caused by the darts 76, 77, 78 to gear with their respective
wheels 47, 48, 49° when such toothed racks 69, 70, 72 are in their highest
positions. When a toothed rack has been caused to gear with one of the
wheels 47, 48, 49° such rack will when being caused to descend by the rotation of
the tappet shaft 67 cause the wheel with which it gears to be turned in the
direction indicated by the arrow U. The movement of the dart 76 in the direction
indicated by the arrow T will have caused such dart 76 to act against the lower
end of the bell-crank-lever 107 and turn such bell-crank-lever 107 in the direction
indicated by the arrow V and raise the tooth 107° clear of the recess in the edge of
the disc 47.
The descent of the rack 69 will cause the disc 47 to perform half a revolution
and the movement of the chain-barrel 81 will have allowed the dart 76 to be
pushed in the direction opposite to that indicated by the arrow T by the
weight of the toothed rack 69 and bell-crank-lever 107 and by a spring.
When a plate of the pattern-chain 100 similar to the plate shown in Fig. 8
is presented to the darts 76, 77, 78 the dart 77 will by the oscillation of the
frame 80 in the direction indicated by the arrow T be carried forward in the
direction indicated by the arrow T and will by the end 77° of the said dart acting
against the toothed rack 70 turn the toothed rack 70 upon the stud 68 and cause
the rack 70 to pass into gear with the wheel 48°. The movement of the dart 77
in the direction indicated by the arrow T will have caused such dart 77 to act
against the lower end of a bell-crank-lever 109 and turn such bell-crank-lever 109
in the direction indicated by the arrow V and raise the tooth upon the said bell-
crank-lever 109 clear of the recess in the edge of the disc 48. The descent of the
rack 70 will cause the disc 48 to perform half a revolution in the direction indicated
by the arrow U and the movement of the chain-barrel 81 will have allowed the
dart 77 to be pushed in the direction opposite to that indicated by the arrow T by
the weight of the toothed rack 70 and bell-crank-lever 109 and by a spring. When
a plate of the pattern-chain 100 similar to the plate shown in Fig. 7 is presented to
the darts 76, 77, 78 the dart 78 will by the oscillation of the frame 80 in the
direction indicated by the arrow T be carried forward in the direction indicated by
the arrow T and will by the end 78 of the said dart 78 acting against the toothed
rack 72 turn the toothed rack 72 upon the stud 71 and cause the rack 72 to pass
into gear with the wheel 49. The movement of the dart 78 in the direction
indicated by the arrow T will have caused such dart 78 to act against the lower
end of a bell-crank-lever 110 and turn such bell-crank-lever 110 in the direction
indicated by the arrow V and raise the tooth upon the said bell-crank-lever 110
clear of the disc 49. The descent of the rack 72 will cause the disc 49 to perform
half a revolution in the direction indicated by the arrow U and the movement of the
chain-barrel 81 will have allowed the dart 78 to be pushed in the direction opposite
to that indicated by the arrow T by the weight of the toothed rack 72 and bell-
crank-lever 110 and by a spring. When the wheel 47° is turned the pin 51 acting
upon the arm 52 will cause such arm 52 to be raised or lowered according as the
pin 51 is situate above or below the axis of the discs 47, 48, 49. The pin 53 will
be slidden along the slot 54 by the rotation of the wheel 47° and will by means of
the pin 53, arm 55 and pin 55 cause the connecting rod 57 to be raised or lowered
through a distance corresponding to the height of one shuttle box. If the
wheel 48 be rotated the pin 55 will cause the arm 55 to be turned upon the
pin 51 and the connecting rod 57 to be raised or lowered through a distance
corresponding to the height of one box according as the pin 55 is situate above or
below the axis of the wheels 47, 48, 49°.
If the wheel 47° and wheel 48° be rotated together through half a rovolution
the pin 56 will be slidden along the slot 49 and the rod 57 will be raised or
lowered through a distance corresponding to the height of two shuttle boxes,
according as the pin 55° is situate above or below the axis of the wheels 47, 48, 49°.
If the wheel 49 be rotated the slot 49% acting upon the pin 56 will cause the

page_text: arm 55 to turn upon the pin 55" and the connecting rod 57 will be raised or lowered
through a distance corresponding to the height of three boxes according as the
pin 55 is situate above or below the axis of the wheels 47, 48°, and 49°.
If the wheels 48 and 49° be rotated together through half a revolution the
plate 55 will be turned around the axis of the pin 51 and thereby cause the rod 57
to be raised or lowered through a distance corresponding to the height of four
shuttle boxes. If the wheels 47, 48 and 49° be rotated simultaneously the pin 56
and connecting rod 57 will be raised or lowered through a distance corresponding
to the height of five boxes, according as the pin 56 is situate above or below the
axis of the wheels 47, 48, 49°.
It will be readily understood from the foregoing that by various combinations of
the rotations of the wheels 47, 48, 49° the connecting rod 57 can be raised or
lowered through a distance corresponding to any desired number of boxes not
exceeding five from or to any position in which such connecting rod 57 may be so
that any of the six shuttle boxes may be brought into position.
Figs. 7, 8, 9, 10, 11, 12, 13 show the various forms of the plates of the pattern-
chain 100 which are requisite for producing the various "changes" of the shuttle
boxes when applying our invention to a loom having six shuttle boxes. The plate
shown in Fig. 14 is employed when no change of the shuttle box is desired.
In the following table No. 1, which requires to be read in connection with the
Figs. 7, 8, 9, 10, 11, 12, 13, 14 of the accompanying drawings, the number in
column 1 indicates the box from which picking has taken place and the number
in column 2 indicates the figure showing the card or plate of the pattern-chajn 100
which has last acted upon certain of the darts 76, 77, 78 and brought the said box
into position for delivering and receiving the shuttle. The number in column 3
indicates the box from which the next pick may be desired to be made and the
number in column 4 indicates the figure showing the card or plate which must be
employed to act upon certain of the darts 76, 77, 78 in order that the desired box
may be brought into position for a pick to be made from it.

page_text: "1
In those cases in which we desire to cause the pattern-chain 100 to be "reversed
we secure to the outer end of the card or plate after which the reversal is to take
place an extra card or plate 108 such as is illustrated in Fig. 16 of the accom-
panying drawings.
The card or plate 108 we secure to a plate of the pattern chain 100 as shown in
Fig. 15 by means of indiarubber and steel rings or by means of a piece of cord.
When the projecting card or plate 108 secured to the pattern-chain 100 is
brought by the rotation of the pattern-chain-barrel 81 into such position that the
oscillation of the pattern-chain-barrel 81 in the direction indicated by the arrow T
will cause the extra card or plate 108 secured to the pattern-chain 100 to act
against one end of the dart 99 so as to move the dart 99 in the direction indicated
by the arrow T such movement of the dart 99 will cause the stud 99 to act against
the toothed rack 98 so as to cause it to gear with the wheel 97 when the toothed.
rack 98 is in its highest position. Upon the toothed rack 98 being lowered the
next lag of the reversing chain 101 which as shown in the drawing will be a lag
similar to 101 will be brought beneath the finger 104 and allow such finger 104
to fall and thus allow the bell-crank-lever 103 to turn upon the stud 102 and thus
cause the arm 85 to be slidden in the direction indicated by the arrow W so as to
cause the pin 89 to act upon the notched wheel 92 and cause the pattern-chain-
barrel 81 to be rotated in a direction opposite to that in which it was previously
rotated. The pattern-chain-barrel 81 will continue to be rotated in the said
direction until its direction is again reversed by an extra card or plate such as 108
attached to the pattern chain 100 at the card or plate at which it is desired that
such pattern chain 100 shall be reversed.
If in the movement of the reversing chain 101 a lag of the pattern-chain 101
similar to the lag 101 be brought beneath the finger 104 the pins 88, 89 will be
placed in such position that they will pass clear of both of the notched wheels 90, 92
so that neither of the notched wheels 90, 92 will be acted upon but when a lag
similar to the lag 101 is brought beneath the finger 104 the said finger 104 will
be raised into its highest position and thus the pin 88 will be caused to act upon
the notched wheel 90 and cause the pattern-chain 100 to be moved in the direction
indicated by the arrow S.
When the loom is being turned "backward" the studs 88, 89 will pass clear
of the notched wheels 90, 92 when the arm 85* is moving in the direction indicated
by the arrow T.
When the loom is turned backward" for any purpose the pattern-chain 100
and, it may be, one or other or two or all of the discs 47, 48, 49 and, it may be,
the reversing chain 101 and shuttle-boxes will be maintained in proper position
relatively to the pattern of the "piece or "cloth" being woven.
::
We have above described our invention as applied to looms having six rising and
falling shuttle boxes but we would have it understood that by the "throw" of each
of the pins 55 and 56 about the axes about which such pins are respectively caused
to revolve being increased as indicated in Fig. 17 by an amount corresponding

page_text: to one half of the distance corresponding to the height of one shuttle box the
invention may be made equally applicable to looms having seven or eight rising
and falling shuttle boxes. The cards of the pattern-chain which are requisite for
causing the various shuttle boxes to be brought into position for delivering or
receiving a shuttle as required are illustrated in Figs. 7, 8, 9, 10, 11, 12, 13 and 14
above described and by means of the table No. 2 following, which has reference to
a loom having eight rising and falling shuttle boxes.
In table 2 the number in column 1 indicates the box which is in position for
delivering or receiving a shuttle, the number in column 2 shows the box which is
to be brought into position for delivering or receiving a shuttle and the number
in column 3 indicates which of the Figures 7, 8, 9, 10, 11, 12, 13 and 14 shows the
card to be employed to bring the required box into position for receiving or
delivering a shuttle.

page_text: The method of operating seven shuttles by means of our invention will be
understood from the preceding explanations of the methods of operating six and
eight shuttle boxes.
In Figs. 18 and 19 is shown a modified arrangement of the parts mounted upon
the discs 47 and 48. In the arrangement shown in Figs. 18 and 19 the arm 55
instead of being provided as in the arrangement shown in side view in Fig. 5 with
a projecting pin 55 projecting into a hole formed in an arm 52 mounted upon the
stud or pin 51 projecting from the boss 47" is made in the form of a strap 55
embracing an excentric 55 mounted upon the stud or pin 51 projecting from the
boss 47. The excentric 55 being the part about which the arm or strap 55 may
be caused to turn is the equivalent of the pin or stud 55" shown in Fig. 5.
operation of the arrangement shown in Figs. 18 and 19 is precisely the same as the
operation of the arrangement shown in Fig. 5 but the excentric 55° shown in
Figs. 18 and 19 affording greater wearing surface than the pin or stud 55ª shown
in Fig. 5 the arrangement shown in Figs. 18 and 19 is less liable to wear or injury
than the arrangement shown in Fig. 5.
The
When applying our invention to looms having revolving or rotary shuttle boxes
we rotate such shuttle boxes by means of a toothed rack and pinion or toothed
racks and pinions such toothed rack and pinion or toothed racks and pinions being
held in gear by means of a spring or springs, the spring or springs yielding in case
an obstruction occurs to the rotation of the boxes thereby preventing breakage or
injury of parts from occurring.
We would have it understood that we make no claim to the use in conjunction
with revolving or rotary shuttle boxes of the above described arrangements by
means of which the pattern-chain may be "reversed" or caused to move in
cither direction or alternately in both directions as we do not intend to use the
said arrangements in conjunction with revolving or rotary shuttle boxes.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The combination of parts consisting in discs such as 47, 48 and 49, arm such
