Improvements connected with Apparatus for Operating the Rising
and Falling Shuttle-boxes of Looms for Weaving.
We JAMES COWBURN of 108 Barton Lane, Eccles in the County of Lancaster,
Manager and CHRISTOPHER PECK of Albert Mill, Silk Street, Eccles in the
County of Lancaster, Manufacturer do hereby declare the nature of this invention
to be as follows:-
Our invention relates to apparatus for operating the rising and falling shuttle-
boxes of looms for weaving.
The first part of our invention relates to looms for weaving in which there are
rising and falling shuttle-boxes at each side and has for its object to render such
looms more efficient and convenient in use than they have hitherto been and
especially to facilitate the production in such looms of such woven fabrics formed
by interweaving with warp two or more kinds of weft as require in parts single
or any odd number of weft threads of any one kind.
This part of our invention consists in simple and efficient means for working the
rising and falling shuttle-boxes at both sides of a loom of the said kind by means
of one pattern-chain or by two or more pattern-chains placed near together moving
similarly and simultaneously so as to be manipulated with practically the same
facility as one pattern-chain and for enabling each of the two pairs or sets of
shuttle-boxes of such loom to be moved independently of the other of such pairs or
sets of shuttle-boxes.
According to this part of our invention we provide at one side of the loom to
which this part of our invention is to be applied two sets of mechanism or devices
for effecting the operation of rising and falling shuttle-boxes and provide means in
which this part of our invention more particularly consists whereby one of such
sets of mechanism or devices is connected to the shuttle-boxes at one side of the
loom while the other of such sets of mechanism or devices is connected to the
shuttle-boxes at the other side of the loom.
In one form of this part of our invention we provide a shaft extending across the
loom and capable of being oscillated in suitable bearings and mount fast upon such
shaft, levers or arms or pinions to or into which are connected or made to gear
connecting rods or levers or racks by means of which motion received from one of
the sets of mechanism or devices for operating rising and falling shuttle-boxes
which are placed at one side of the loom is communicated to the rising and falling
shuttle-boxes at the other side of the loom and mount so that it is capable of being
oscillated or turned upon such shaft a lever or pinion or other part or parts by
means of which motion received from the other of the sets of mechanism or devices
for operating rising and falling shuttle-boxes placed at one side of the loom is
communicated to the rising aud falling shuttle-boxes at such side of the loom.
In another form of this part of our invention we employ instead of the shaft
above mentioned as extending across the loom two or more shafts connected
together by means of any suitable kind of gearing. In some cases the lever or pinion
or other part or parts above mentioned as being mounted upon the shaft above
described as extending across the loom may instead of being mounted upon such
shaft be mounted upon any suitable shaft or stud or be mounted upon a shaft or stud
specially provided to receive it or them or be supported in any other suitable manner.
Each of the sets of mechanism or devices for operating rising and falling shuttle-
boxes provided in a loom to which this part of our invention is applied may be of any

page_text: suitable construction but must obviously be adapted to the number of rising and
falling shuttle-boxes to be operated by it, and there may be more shuttle-boxes at
one side of the loom than at the other. The pattern-chain or pattern-chains
employed in a loom to which this part of our invention is applied may be formed of
cards or plates or lags or of plates or lags with pins or other equivalent devices
inserted in or secured on them in the requisite positions or may be made of pins or
axles with bowls or rollers threaded or placed thereon in suitable positions, or of
links of different sizes or be of any other suitable construction and such pattern-
chain or pattern-chains may itself or themselves be made to impart movement to
or permit the movement of the shuttle-boxes or be employed in conjunction with
darts or needles or other devices which by being moved or left unmoved may be
employed to control or effect the movement of other parts capable of causing or
controlling the movement of the shuttle-boxes. When darts or needles or other
devices to be operated upon by the pattern-chain or pattern-chains employed are
provided in the sets of mechanism or devices for effecting the operation of rising
and falling shuttle-boxes provided in a loom to which this part of our invention is
applied, such darts or needles or other devices inust be so disposed that the action
of such darts or needles or other devices shall be controlled by one pattern-chain
or by two pattern-chains placed near together and moving similarly and simul-
taneously and the said pattern-chain or pattern-chains may be revolved and
presented to the darts or needles or other devices with which it is or they are
employed in any suitable manner and by any suitable means.
In some cases in applying this part of our invention we arrange the loom in any
suitable manner so that such loom shall work or be capable of working "pick and
pick" so that from either side of the loom two or more shuttles may be delivered
successively and in such cases we may provide a dart or needle or darts or needles
or other suitable device or devices to be acted upon by the pattern-chain or pattern-
chains employed so that the loom may be caused to work "pick and pick "from either
side or so that shuttles may be delivered from either side alternately, and when this
part of our invention is so employed we arrange the mechanism employed to operate
the shuttle-boxes so that whenever it may be necessary or desirable the shuttle-boxes
at both sides of the loom shall be moved simultaneously though not necessarily
always in the same direction or always in opposite directions. The mechanism by
means of which the picking is effected may be so arranged that ordinarily shuttles
may be delivered from each side of the loom alternately and when the dart or
needle or darts or needles or other device or devices employed to control the
picking is or are acted upon by the pattern-chain or pattern-chains employed,
two or more picks according to the number of shuttle-boxes may be delivered
successively from one side of the loom.
In a loom to which this part of our invention is applied there may be provided
mechanism of any suitable kind by which the pattern-chain or pattern-chains
causing or controlling the movement of the two pairs or sets of rising and falling
shuttle-boxes may be caused to revolve forwards, cease revolving or revolve back-
wards as may be desirable or necessary from time to time and there may be provided
mechanism either such as is hereinafter described in reference to a further part of
our invention or of any other suitable kind by which a supplementary or controlling
pattern-chain or lag-chain by means of which the said pattern-chain or pattern-
chains causing or controlling the movements of the shuttle-boxes may be caused to
revolve forwards, cease revolving or revolve backwards and there may be provided
mechanism either such as is hereinafter described in reference to a further part of
our invention or of any other suitable kind by which the pattern-chain or either of
the pattern-chains causing or controlling the movements of the shuttle-boxes may
be enabled to cause the said supplementary or controlling pattern-chain or lag-chain
to revolve or cease revolving as may be necessary or desirable from time to time.
A further part of our invention also relates to looms for weaving in which there
are rising and falling shuttle-boxes at each side, and has for its object to render
such looms more efficient and convenient in use than they have hitherto been and

page_text: especially to facilitate the production of such woven fabrics formed by inter-
weaving with warp two or more kinds of weft as require in any parts single or any
odd number of weft threads of any one kind. This part of our invention consists
in arrangements of apparatus by means of which the shuttle-boxes of a loom provided
with rising and falling shuttle-boxes at each side may be very conveniently and
efficiently operated by means of one pattern-chain while each of the two pairs or sets
of shuttle-boxes of such loom may be moved independently of the other of such pairs
or sets of shuttle-boxes. According to this part of our invention as applied to a loom
provided with two rising and falling shuttle-boxes at each side we provide at one
side of the loom to which this part of our invention is to be applied two discs each
of which is provided with a crank-pin or excentric embraced by or arranged to
operate a connecting rod. If provided with a crank-pin each of the said
discs may be mounted so as to be capable of rotating upon a stud or may
be formed with a stud or axle capable of being revolved in a suitable
bearing and if such discs be provided with excentrics each of the said
discs may be mounted so as to be capable of rotating upon a stud or may
be formed with a stud or axle capable of being revolved in a suitable bearing or
the two excentrics may be mounted so as to be capable of being revolved upon an
axle mounted in any suitable support. The connecting rod embracing the crank-
pin or excentric upon one of the said dises is connected to the rising and falling
shuttle-boxes at the said side of the loom by means of a lever mounted loose upon
shaft extending across the loom and capable of being oscillated in suitable
bearings, and a connecting rod in order that the turning of the said disc may cause
the said shuttle-boxes to be raised or lowered. The connecting rod embracing the
crank-pin or excentric upon the other of the said discs is connected to the rising
and falling shuttle-boxes at the other side of the loom by means of arms or levers
and the above mentioned shaft extending across the loom so that the turning of the
said disc will cause the said shuttle-boxes to be raised or lowered. To or upon
each of the said discs is secured or formed a pinion and in conjunction with the
pinions there are provided racks in conjunction with which there are provided darts
or needles by means of which the said racks may be pressed into engagement with
the pinions in conjunction with which they are respectively employed so that rotary
motion may be imparted to such pinious by the said racks which are also arranged
to be moved by being jointed to arms or levers which are oscillated by means of a
connecting rod receiving motion from a crank or cam which in cases in which it is
necessary to weave a single pick or thread or any odd number of successive picks
or threads of weft of any one of the kinds of weft employed at any part of the cloth
or fabric being woven, must be made to revolve with the same angular velocity as
the crank-shaft of the loom although it may be mounted upon the tappet shaft of
the loom or in or upon any other part which may be convenient, but in other cases
may be mounted fast upon the tappet-shaft of the loom or upon any other suitable
shalt revolving with the same angular velocity as the tappet-shaft. The
disengagement of the racks above mentioned from the pinions in conjunction with
which they are employed may be accomplished by such racks being arranged so as
to tend to fall away from the said pinions or in any other convenient manner.
conjunction with the darts or needles above mentioned we provide a pattern-chain-
barrel which is supported and moved towards and away from the said darts or
needles by means of a frame or lever which is oscillated by means of a cam
revolving at the same speed as and preferably mounted upon the same shaft or part
as the crank or cam which is above mentioned as being employed to move the racks
above referred to. The pattern-chain-barrel above mentioned is revolved by
means of a wheel or equivalent part to which motion is imparted by the action of
a stud or pin projecting from an arm oscillating simultaneously with the arms or
levers by which the racks above mentioned are moved and preferably mounted
upon the same axle or pivot as such arms or levers so as to be moved therewith and
by the same means. In conjunction with the discs above mentioned we may
provide detents which may be in the form of levers capable of being oscillated and
In

page_text: are kept in engagement with notches in the said discs by their own weight or by
springs or any other suitable means and are acted upon so as to be disengaged
therefrom when such discs are required to revolve, by the darts or needles
respectively employed in conjunction with the racks respectively employed to
impart motion to such discs.
According to this part of our invention as applied to a loom provided with more
than two rising and falling shuttle-boxes at either side we provide at one side of
the loom two connecting rods adapted to embrace excentrics or crank-pins as will
be hereinafter mentioned one of which connecting rods is connected to the shuttle-
boxes at one side of the loom, by means of a connecting rod and a lever mounted
loose upon a shaft extending across the loom and capable of being oscillated in
suitable bearings, while the other of the two connecting rods above mentioned as
being provided at one side of the loom is connected by means of a connecting rod
and arm to the above mentioned shaft extending across the loom and another lever
or arm and connecting rod, to the shuttle-boxes at the other side of the loom. In
conjunction with each of the two connecting rods which as above mentioned we
provide at one side of the loom we employ two discs if three or four shuttle-boxes
are to be operated by means of such connecting rod or three discs if from five to
eight shuttle-boxes are to be operated by means of such connecting rod.
When
two discs are employed in conjunction with a connecting rod, one disc is provided
with an excentric or crank-pin and upon such excentric or crank-pin is mounted an
excentric or crank and the said excentric or the crank-pin upon the said crank is
embraced by the said connecting rod while a pin upon the excentric or the crank-
pin embraced by the said connecting rod is caused to engage with the other disc so
that by the turning of such disc the said excentric or crank may be turned in
relation to the excentric or crank-pin upon which it is mounted and thus by one or
other or both of the said dises being turned into position as may be requisite the
shuttle-boxes in connection with which the said connecting rod is employed may
be raised and lowered as may be necessary, the excentricities of the said excentrics
or crank-pins being made such that the requisite amount of motion may be imparted
to the said shuttle-boxes. When the one disc is provided with an excentric upon
which is mounted a second excentric both of the dises employed may be mounted
upon one stud or axle and consequently when two pairs of discs arranged in the
said manner are employed in conjunction with the two connecting rods respectively
employed to transmit motion to the shuttle-boxes at the two sides of the loom, the
four discs may all be mounted upon one stud or axle. When three discs are
employed in conjunction with either of the two connecting rods which as above
mentioned we provide at one side of a loom one of the said discs is provided with
an excentric or crank-pin upon which is mounted an excentric or crank capable of
being turned upon the excentric or crank-pin upon which it is mounted by being
placed in engagement with a slot or projection in or upon the second disc and upon
such excentric or crank is mounted a crank which is capable of being turned about
the excentric or crank-pin upon which it is mounted by being placed in engagement
with the third disc. The excentricities of the several excentrics or crank-pins
employed in conjunction with the said discs being proportioned to the various
movements requisite to be imparted to the shuttle-boxes to which motion is to be
imparted by means of the connecting rod in conjunction with which such discs are
employed, such shuttle-boxes may be moved into the various positions requisite
from time to time by the turning of one or other or any two or all of the said dises
into position as may be requisite. The means by which the movements of the four
or five or six discs employed according to our invention in a loon with four or from
five to eight shuttle-boxes at one side and four or five to eight shuttle-boxes at the
other side are effected and controlled by means of the pattern-chain employed, are
substantially similar to those above described as being employed in a loom
provided with only two shuttle-boxes at each side except in so far as each disc
being provided with a pinion requires a distinct rack and a distinct dart or needle
and detent to be employed in conjunction with it and consequently the pattern-chain

page_text: and pattern-chain-barrel must be adapted to act upon the darts or needles which
it is requisite to employ.
This part of our invention may be applied to looms arranged to work or to be
capable of working "pick and pick." so that two or more shuttles according to
the number of shuttle-boxes provided may be delivered successively from the
shuttle-boxes at one side of the loom and when this part of our invention is so
applied we provide a needle or dart or equivalent device or needles or darts or
equivalent devices to be acted upon by the pattern-chain in order that the picking
may take place from one side of the loom twice or three or more times in
succession according to the number of shuttle-boxes or alternately from each
side of the loom as may be necessary or desirable from time to time and we prefer
to so arrange the mechanism by which the picking is effected and controlled that
ordinarily shuttles shall be delivered from each side of the loom alternately and
when the dart or needle or other device or darts or needles or other devices
provided for the purpose is or are acted upon by the pattern-chain two or more
successive picks according to the number of shuttle-boxes shall be delivered from
one side of the loom. When this part of our invention is applied to a loom which
may at any time be required to work "pick and pick" the mechanism by which
the movements of the shuttle-boxes at the two sides of the loom are effected and
controlled must be so arranged that whenever it may be requisite the shuttle-
boxes at both sides of the loom shall be moved simultaneously though not necessarily
always in the same direction or always in opposite directions.
We have above described this part of our invention as being so applied that
the transmission of motion from the sets of mechanism above described as
respectively employed according to this part of our invention to effect the operation
of the rising and falling shuttle-boxes at the two sides of the loom, is effected in
the case of the shuttle-boxes at one side of the loon by means of connecting
rods and a lever mounted loose upon a shaft extending across the loom and in the
case of the shuttle-boxes at the other side of the loom by means of connecting
rods connected to arms or levers mounted fast upon such shaft but instead of
connecting rods jointed to arms or levers there may be provided connecting rods
provided with racks gearing into pinions and instead of one shaft extending across
the loom there may be provided two or more shafts connected together by gearing
of any suitable kind and in some cases the lever or pinion employed in the trans-
mission of motion to the shuttle-boxes which are at the same side of the loom
as the sets of mechanism employed to operate the shuttle-boxes may instead of
being mounted upon the said shaft be mounted upon any suitable shalt or stud or
upon a shaft or stud provided for the purpose of receiving such lever or pinion
aud we would have it understood that as is obvious from the description above
given of a former part of our invention these arrangements for transmitting motion
to the shuttle-boxes form in themselves a distinct part of our invention and we
would also have it understood that in conjunction with the above described arrange-
ments of crank-pins, cranks or excentrics and racks and pinions there may be
employed any other means for transmitting motion to the shuttle-boxes to be
operated by means of such arrangements of crank-pins, crauks or excentrics and
racks and pinions.
A further part of our invention relates to looms for weaving in which there are
rising and falling shuttle-boxes at each side and consists in arrangements by means
of which the pattern-chains employed to act upon the darts or needles in
looms of the said kind to which are applied the arrangements of discs
and cranks or excentrics which have been herein before described may be caused
to be revolved forwards or to cease revolving or to be revolved backwards.
According to this part of our invention we mount upon the pattern-chain-
barrel upon which is mounted the pattern-chain employed to act upon the
darts or needles of a loom to which this part of our invention is to be applied
a wheel or equivalent device and provide a second wheel or equivalent device
connected to the said pattern-chain-barrel by suitable gearing so that one of such

page_text: wheels or equivalent devices may be employed to revolve the said pattern-chain-
barrel in a direction contrary to that in which the other of such wheels or
equivalent devices would revolve such pattern-chain-barrel, and we provide an
arm provided with two studs or two arms each provided with a stud or two devices
of any other suitable kind to act upon the said wheels or equivalent devices so
that one or other of the said wheels or equivalent devices may be employed to
revolve the said pattern-chain-barrel as may be necessary or desirable from time
to time and in order that one or other of the said studs or other devices provided
for the purpose may be caused to act upon the wheel or equivalent device in
conjunction with which it is employed or so that both of such studs or other
devices may be placed out of action we provide a supplementary or controlling
pattern-chain which may conveniently be in the form of a lag-chain with lags of
three different heights and cause such supplementary or controlling pattern-chain
to bring one or other of the said studs or other devices into position to be made
to act upon the wheel or equivalent device in conjunction with which it is employed
or to place both of such studs or other devices out of action. In order that the
said supplementary or controlling pattern-chain may be caused to revolve or cease
revolving for a time as may be necessary or desirable we mount such supplementary
or controlling pattern-chain upon a pattern-chain-barrel to which motion may be
imparted by means of a rack moved at the same time and it may be by the
same means as the racks above described as being employed to impart motion to
the discs above described and provide a dart or needle to bring the said rack into
gear and cause such dart or needle to be acted upon from time to time by means
of the pattern-chain employed to control the movements of the shuttle-boxes or by
means of supplementary cards attached at the requisite parts to such pattern-chain.
In some cases we may dispense with means for enabling the pattern-chain controlling
the movement of the shuttle-boxes to control the movement of the supplementary
or controlling pattern-chain.

Improvements connected with Apparatus for Operating the Rising
and Falling Shuttle-boxes of Looms for Weaving.
We, JAMES COWBURN, of 108 Barton Laue, Eccles, in the County of Lancaster,
Manager, and CHRISTOPHER PECK, of Albert Mill, Silk Street, Eccles, in the
County of Lancaster, 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 apparatus for operating the rising and falling shuttle
boxes of looms for weaving.
The first part of our invention relates to looms for weaving in which there are
rising and falling shuttle-boxes at each side, and has for its object to render
such looms more efficient and convenient in use than they have hitherto been
and especially to facilitate the production of such woven fabrics formed by inter-
weaving with warp two or more kinds of weft as require in any parts single
or any odd numbers of weft threads of any one kind. This part of our invention
consists in arrangements of apparatus by means of which the shuttle-boxes of a
loom provided with rising and falling shuttle-boxes at each side may be very
conveniently and efficiently operated by means of one pattern-chain while each
of the two pairs or sets of shuttle-boxes of such loom may be moved independently
of the other of such pairs or sets of shuttle-boxes. According to this part of our
invention as applied to a loom provided with two rising and falling shuttle-boxes

page_text: at each side we provide at one side of the loom to which this part of our
invention is to be applied two discs each of which is provided with a crank-pin
or excentric embraced by or arranged to operate a connecting rod. If provided
with a crank-pin each of the said discs may be mounted so as to be capable of
rotating upon a stud or may be formed with a stud or axle capable of being
revolved in a suitable bearing and if such discs be provided with excentrics each of
the said discs may be mounted so as to be capable of rotating upon a stud or may
be formed with a stud or axle capable of being revolved in a suitable bearing
or the two excentrics may be mounted so as to be capable of being revolved upon
an axle mounted in any suitable support. The connecting rod embracing the
crank-pin or excentric upon one of the said discs is connected to the rising and
falling shuttle-boxes at the said side of the loom by means of a lever mounted'
loose upon a shaft extending across the loom and capable of being oscillated in
suitable bearings, and a connecting rod in order that the turning of the said dise
may cause the said shuttle-boxes to be raised or lowered. The connecting rod
embracing the crank-pin or excentric upon the other of the said discs is connected
to the rising and falling shuttle-boxes at the other side of the loom by means of
arms or levers and the above mentioned shaft extending across the loom so that.
the turning of the said disc will cause the said shuttle-boxes to be raised or
lowered. To or upon each of the said discs is secured or formed a pinion and in
conjunction with the pinions there are provided racks in conjunction with which.
there are provided darts or needles by means of which the said racks may be.
pressed into engagement with the pinions in conjunction with which they are
respectively employed so that rotary motion may be imparted to such pinions by
the said racks which are also arranged to be moved by being jointed to arms or
levers which are oscillated by means of a connecting rod receiving motion from a
crank or cam which in order that it may be possible to weave a single pick or
thread or any odd number of successive picks or threads of weft of any one of the
kinds of weft employed at any part of the cloth or fabric being woven, is made to.
revolve with the same angular velocity as the crank-shaft of the loom although it
may be mounted upon the tappet-shaft of the loom or in or upon any other part
which may be convenient. The disengagement of the racks above mentioned from
the pinions in conjunction with which they are employed may be accomplished by
such racks being arranged so as to tend to fall away from the said pinions or in
any other convenient manner. In conjunction with the darts or needles above
mentioned we provide a pattern-chain-barrel which supported and moved towards
and away from the said darts or needles by means of a frame or lever which is.
oscillated by means of a cam revolving at the same speed as and preferably
mounted upon the same shaft or part as the crank or cam which is above mentioned
as being employed to move the racks above referred to. The pattern-chain-barrel
above mentioned is revolved by means of a wheel or equivalent part to which
motion is imparted by the action of a stud or pin projecting from an arm oscillating-
simultaneously with the arms or levers by which the racks above mentioned are
moved and preferably mounted upon the same axle or pivot as such arms or levers:
so as to be moved therewith aud by the same means. In conjunction with the
discs above mentioned we provide detents which may be in the form of levers
capable of being oscillated and are kept in engagement with notches in the said
dises by their own weight or by springs or any other suitable means and are acted
upon so as to be disengaged therefrom when such discs are required to revolve by
the darts or needles respectively employed in conjunction with the racks respectively
employed to impart motion to such discs.
In the accompanying drawings, Figs. 1, 2, 3 and 4 illustrate the application of
this part of our invention to a loom provided with two rising and falling shuttle-
boxes at each side, Fig. 1 being a side elevation of so much of such loom as is
requisite for the illustration of the said application of this part of our invention,
Fig. 2 a plan of part of the mechanism which is employed in the said application
of this part of our invention and Fig. 3 is a diagram illustrating certain parts of

page_text: such mechanism apart from the other parts thereof, and Fig. 4 is a diagram
illustrating an alternative construction and arrangement of part of the mechanism
which we employ in the said application of this part of our invention.
In Figs. 1, 2, 3 and 4 of the accompanying drawings (m) (n) are the two discs
which we provide at one side of the loom in applying this part of our invention
to a loom provided with two rising and falling shuttle boxes at each side. As the
parts by means of which each of the discs (m) (n) is supported and moved and
held in the positions requisite are in part the same as and in part similar to the
parts by means of which the other of such discs is supported and moved and held
in the positions requisite we have in the accompanying drawings applied the same
letters of reference to each of the several similar parts and in order to render it
easy to distinguish whenever it may be necessary or desirable to do so between the
several similar parts we have added as an affix to the reference letter applied to
each of such similar parts the reference letter applied to the disc in conjunction
with which such part is employed. In Figs. 1, 2, and 3 the discs (m) (n) are
illustrated as being each provided with a crank-pin (o) and in Fig. they are
illustrated as being each provided with an excentric (p). If provided as we
prefer, with a crank-pin (o) each of the said discs (m) (n) may, as is illustrated in
Figs. 1, 2 and 3 be formed with a stud or axle capable of being revolved in a
suitable bearing formed in a bracket (9) secured to one of the side-frames of the
loom, that is to say to the side-frame () or may be capable of being rotated upon
a stud and if such discs (m) (n) be provided with excentrics (p) each of them may
as is illustrated in Fig. 4 be mounted so as to be capable of being rotated upon an
axle (r) mounted in a bracket (7) secured to one of the side-frames of the loom,
that is to say to the side-frame (b). The crank-pin (m) or excentric (pm) with
which the disc (m) is provided is embraced by a connecting rod (j) or by a
strap (40) connected to such connecting rod which is connected to the rising and
falling shuttle-boxes (k) at the said side of the loom by means of a lever (4)
mounted loose upon a shaft (a) extending across the loom, and capable of being
oscillated in bearings in the side-frames (b) (61) of the loom, and a connecting
rod (i) and thus the turning of the disc (m) will cause the said shuttle-boxes (k) to
be raised or lowered. In the arrangement illustrated in Figs. 1, 2 and 3 the
connecting rod (f) is provided with a plate (f) which serves to keep the con-
necting rods (j) (f) in position upon the crank-pins (o) which they respectively
embrace and also to keep each of the discs (m) (n) in position in the bracket (1).
The connecting rod (7) embracing the crank-pin (on) or connected to the
strap (41) embracing the excentric (pn) upon the disc (n) is connected to the
rising and falling shuttle-boxes (9) at the other side of the loom by means of
the shaft (a) above mentioned and levers (c) (d) and thus the turning of the disc (n)
will cause the said shuttle-boxes (g) to be raised or lowered. The excentricity of
the crank-pin (o) or excentric (p) upon each of the discs (m) (n) is made such that
the turning of the disc on which such crank-pin (0) or excentric (p) is formed or
mounted through half a revolution from or into the position in which it is indicated
in Figs. 2, 3 and 4 will cause the shuttle-boxes (9) or (k) moved by means of such
crank-pin (o) or excentric (p) to be raised or lowered through a distance equal to
the distance between the centre of one of such shuttle-boxes (7) or (k) and the
centre of the other of such shuttle-boxes (g) or (k). The disc (m) is provided with
a pinion (tm) and the disc (n) is provided with a pinion (tn). A rack (um) is
provided to act in conjunction with the pinion (tm) and a dart or needle (m)
supported and guided by the bracket (2) is provided to enable the rack (um) to
be pressed into engagement with the pinion (tm). A rack (un) is provided to act
in conjunction with the pinion (tn) and a dart or needle (vn) supported and guided
by the bracket (y) is provided to enable the rack (an) to be pressed into engage-
ment with the pinion (tn). The racks (um) (un) are jointed to levers (w m) (wn)
which are formed upon a barrel (w) which is mounted fast upon an axle (w2)
supported in bearings formed in the bracket (7) and is oscillated by means of a
connecting rod (*) receiving motion from a crank (y) provided with a sleeve (y 2)

page_text: secured by means of a set screw in position upon another sleeve (y') cible of
being revolved upon the tappet shaft (=) of the loom and receives motion by means
of the wheels (9) (10) (11) (12), the wheel (9) being mounted fast upon the crank-
shaft (13) of the loom, the wheels (10) (11) being carrier-wheels capable of being
revolved upon studs secured to the side-frame (6) of the loom and the wheel (12)
being mounted fast upon the said sleeve (y'). The said sleeve (y') is made to
revolve with the same angular velocity as the said crank-shaft (13) in order that
it may be possible to weave a single pick or thread or any odd number of successive
picks of weft of any one of the kinds of weft employed at any part of the cloth or
fabric being woven whenever it may be necessary or desirable to do so.
The dis-
engagement of the racks (um) (un) from the pinions (tm) (tn) in conjunction with
which they are respectively employed is accomplished by such racks (um)
(un) being arranged to fall away from the said pinions (tm) (tn). In conjunction
with the darts or needles (um) (on) we provide a pattern-chain-barrel (14) which
is supported and moved towards and away from the darts or needles (um) (vn) by
means of a frame or lever (15) which is mounted upon an axle (15) secured in the
bracket (9) and is oscillated in the direction indicated by the arrow (A) by.
means of a cam (16) mounted upon the sleeve (y 2) provided upon the crank (y)
and in the direction opposite to that indicated by the arrow (A) by means of a
spring (17) connected at one end to the lever or frame (15) and at the other end
to the side-frame (b) of the loom. The pattern-chain-barrel (14) is revolved by
means of one or other of two notched wheels (18) (19) to one or other of which
motion is imparted by the action of a stud (20) projecting from an arm (20)
mounted fast upon the axle (w2) upon which the barrel (w') is mounted so as to
be oscillated by the crank (y) simultaneously with the arms or levers (wm) (wn).
The stud (20) engages with a slot formed in an arm (21) which is mounted upon
an axle (21) capable of being oscillated in bearings provided in the bracket (g)
and capable of being moved longitudinally therein for the purpose of enabling the
pattern-chain-barrel (14) to be turned in one direction or the other or allowed to
remain stationary as will be hereinafter explained, and is provided with two
studs (22) (23) so arranged that according as the arm (21) is caused to oscillate
in one or other of two positions the stud (22) will be caused to pass into engagement
with and turn the notched wheel (18) which is mounted fast upon the axle of the
pattern-chain-barrel (14) or the stud (23) will be caused to pass into engagement
with and turn the notched wheel (19) which is mounted so as to be capable of being
revolved upon a stud secured in the lever or frame (15) and is provided with a
pinion gearing into or engaging with another piuion of equal diameter provided
upon the notched wheel (18). By the pattern-chain-barrel (14) being caused to
receive motion by means of the notched wheel (18) or the notched wheel (19) the
pattern-card-chain (24) mounted upon the said pattern-chain-barrel (14) may be
caused to revolve in one direction or the other as will be hereinafter further
described. The can (16) is so formed and disposed in relation to the crank (y)
that while the loon is weaving the turning of the pattern-chain-barrel (14) by the
Jever (21) will take place while the said pattern-chain-barrel (14) is in or near
the position which it occupies at the end of its movement in the direction opposite
to that indicated by the arrow (A) and while the lever (21) is being moved in the
direction indicated by the arrow (K). The lever or arm (21) is formed in two
parts secured together by means of a bolt so that the position of the studs (22) (23)
relative to the axle (21) may be adjusted as may be requisite. In conjunction
with the discs (m) (n) there are provided detents in the form of levers (25") (25º)
capable of being oscillated on an axle (25%) secured in the bracket (7). The
detents (25) (25º) are kept in engagement with notches in the discs (m) (n) in
conjunction with which they are respectively employed by means of springs (26)
secured to the bracket (9) and arranged to act upon the lower arms of such
detents (25) so as to turn such detents in the direction indicated by the arrow (B).
When the dart or needle (v) employed to press into engagement with the pinion (t)
provided upon one or other of the discs (m) (n) the rack (u) employed therewith,.
B

page_text: such dart or needle (v) acting by means of a shoulder or projection formed upon
it upon the lower arm of the detent (25) employed in conjunction with such disc
will turn such detent (25) in the direction opposite to that indicated by the
arrow (B) and cause it to release the said disc. The crank-pin () is so placed
that if the rack (u) employed in conjunction with either of the discs (m) (n) be
placed in engagement with the pinion (t) in conjunction with which it acts when
such rack (u) is in its highest position and he kept in engagement with such
pinion (t) while being moved into its lowest position, the said pinion (t) and the
disc (m) (n) with which it is employed will be turned through one half of a
revolution in the direction indicated by the arrow C. The cam (16) which is
formed with a slot so that it may be readily adjusted in position in relation to the
crank (y) to which it is secured by means of a bolt is so formed and placed in
such relation to the crank (y) and the said cam (16) and crank (y) are placed so
as to revolve in such relation to the cranks upon the crank-shaft (13) of the
loom which are employed to move the slay (27) that when the loom is weaving
the pattern-chain-barrel (14) shall be moved in the direction indicated by the
arrow (A) so as to cause the card or plate of the pattern-card-chain (24) thereon
which is presented to the darts or needles (v) if of a character suitable to produce
such an effect to move either of the darts or needles (r) and press the rack (u)
with which such dart or needle (v) is employed into engagement with the pinion (1)
in conjunction with which it is employed after a pick or thread of weft has been
laid across the warp being woven into a fabric or cloth and before the slay (27) has
moved forward to "beat up "such pick or thread so that during the succeeding
half revolution of the crank-shaft (13) of the loom the said rack (u) will turn the
disc (m) or (n) in conjunction with which such rack () is employed through a
half revolution in the direction indicated by the arrow (C) so as to have completed
the required change in the position of the shuttle-boxes moved by means of such
disc by the time at which the next pick or thread of weft is required to be laid
across the warp. The cam (16) is also so formed that the racks (um) (un) when
pressed into engagement with the pinions (tm) (tn) in conjunction with which they
are respectively employed will be kept in engagement therewith until such
pinions (m) (tn) have been moved through half a revolution by the action of the
crank (y) and then allow such racks (um) (un) to fall away from and out of
engagement with such pinions (m) (tn) and also allow the detents (25") (25") to
be turned in the direction indicated by the arrow (B) and pass into engagement
with the discs (m) (n) in conjunction with which they are respectively employed.
When the loom illustrated in Figs. 1 and 2 of the accompanying drawings is
turned backwards for unweaving or any other purpose the pattern-chain-barrel (14)
is so moved that the engagement of either of the racks (u) with the pinion (t) in
conjunction with which it is employed will take place when such rack (u) is in its
lowest position, so that the revolution of the crank (y) will at such times cause
the disc (m) or (n) with which such rack (") is employed to be turned in the
direction opposite to that indicated by the arrow (C) and the engagement of
the stud (22) with the notched wheel (18) or the stud (23) with the notched
wheel (19) will take place while the pattern-chain-barrel (14) is in or near the
position which it occupies at the end of its movement in the direction opposite to
that indicated by the arrow (A) and while the lever (21) is being moved in the
direction opposite to that indicated by the arrow (K) and thus the pattern-card-
chain (24) and shuttle-boxes (y) (k) will be kept in proper relation to the pattern
of the " piece or cloth being woven in the loom.

According to this part of our invention as applied to a loom provided with more
than two rising and falling shuttle-boxes at each side we provide at one side of the
loom two connecting rods adapted to embrace excentrics or crank-pins as will be
hereinafter mentioned one of which connecting rods is connected to the shuttle-
boxes at one side of the loom by means of a connecting rod and a lever mounted
loose upon a shaft extending across the loom and capable of being oscillated in
suitable bearings, while the other of the two connecting rods above mentioned

page_text: as being provided at one side of the loom is connected by means of a connecting
rod and arm to the above mentioned shaft extending across the loom an another
lever or arm and connecting rod to the shuttle-boxes at the other side of the
loom. In conjunction with each of the two connecting rods which as above.
mentioned we provide at one side of the loom we employ two discs if three or four
shuttle-boxes are to he operated by means of such connecting rod or three discs if
from five to eight shuttle-boxes are to be operated by means of such connecting
rod. When two discs are employed in conjunction with a connecting rod one disc
is provided with an excentric or crank-pin and upon such excentric or crank-pin is
mounted an excentric or crank and the said excentric or the crank-pin upon the
said crank is embraced by the said connecting rod while a pin up n the excentric
or the crank pin einbraced by the said connecting rod is caused to engage with the
other disc so that by the turning of such disc the said excentric or crank may be
turned in relation to the excentric or crank-pin upon which it is mounted and thus
by one or other or both of the said discs being turned into position as may be
requisite the shuttle-boxes in connection with which the said connecting rol is
employed may be raised and lowered as may be necessary, the excentricities of the
said excentrics or crank-pins being made such that the requisite amount of motion
may be imparted to the said shuttle-boxes. When the one disc is provided with
an excentric upon which is mounted a second excentric both of the discs employed may
be mounted upon one stud or axle and consequently when two pairs of discs
arranged in the said manner are employed in conjunction with the two connecting
rods respectively employed to transmit motion to the shuttle-boxes at the two sides
of the foom the four discs may all be mounted upon one stud or axle. When
three discs are employed in conjunction with each of the two connecting rods
which as above mentioned we provide at one side of a loom one of the said discs is
provided with an excentric or crank-pin upon which is mounted an excentric or
crank capable of being turned upon the excentric or crank-pin upon which it is
mounted by being placed in engagement with a slot or projection in or upon the
second disc and upon such excentric or crank is mounted an excentric or crank
which is capable of being turned about the excentric or crank-pin upon which it is
mounted by being placed in engagement with the third disc. The excentricities of
the several excentrics or crank-pins employed in conjunction with the said dises
being proportioned to the various movements requisite to be imparted to the
shuttle-boxes to which motion is to be imparted by means of the connecting rod in
conjunction with which such discs are employed such shuttle-boxes may be moved
into the various positions requisite from time to time by the turning of one or
other or any two or all of the said discs into position as may be requisite. The
means by which the movements of the four or six discs employed according to our
invention in a loom with four or from five to eight shuttle-boxes at each side are
effected and controlled by means of the pattern-chain employed are substantially
similar to those above described as being employed in a loom provided with only
two shuttle-boxes at each side except in so far as each disc being provided with a
pinion requires a distint rack and a distinct dart or needle and detent to be
employed in conjunction with it and consequently the pattern-chain and pattern-
chain-barrel must be adapted to act upon the darts or needles which it is requisite
to employ.
In the accompanying drawings, Figs. 5, 6, 7, 8, 9 and 10 illustrate the applica-
tion of this part of our invention to a loom provided with four rising and falling
shuttle-boxes at each side, Fig. 5 being a side elevation, Fig. 6 a front elevation
aud Fig. 7 a plan, of so much of such loom as is requisite for the illustration of
The said application of this part of our invention; Fig. 8 a side elevation and
Fig. 9 a plan drawn upon a larger scale than Figs. 5 and 6 and 7 showing part of
the mechanism which is employed in the said application of this part of our
invention, and Fig. 10 is a section taken upon the plane indicated by the line D D
of Fig. 5.
Certain of the parts shown in Figs. 5, 6, and 7 are similar to certain parts which

page_text: are illustrated in Figs. 1 and 2 and have already been herein described, and we
have therefore applied to the parts shown in Figs. 5, 6, 7, 8, 9, and 10 which are
similar to parts shown in and already described in reference to Figs. 1 and 2 the
same letters of reference as are applied to the corresponding parts in Figs. 1 and 2
and we will therefore now only refer to such parts in so far as is necessary for the
description of the parts which we have not already herein described in reference
to Figs. 1 and 2. In Figs. 5, 6, 7, 8, 9 and 10 of the accompanying
drawings (m) (m²) (n) (n¹) are the four discs which we provide in conjunction
with the two connecting rods (j) (f) which we provide at one side of the loom in
applying our invention to a loom provided with four rising and falling shuttle-
boxes at each side. As the parts by means of which each of the discs (m) (m³)
(n) (n) is moved and held in the positions requisite are in part the same as and in
part similar to the parts by means of which each of the others of such discs is
moved and held in the positions requisite we have in Figs. 5, 6, 7, 8, 9 and 10 of
the accompanying drawings, in order to facilitate the description thereof applied
the same letters of reference to each of the several similar parts and in order to
render it easy to distinguish whenever it may be necessary to do so between
the similar parts, we have added as an affix to the reference letter applied to each
of such similar parts the reference letter applied to the dise in conjunction with
which such part is employed. The connecting rod (j) is connected to the shuttle-
boxes (k) situate at the same side of the loom as such connecting rod (j), by
means of a connecting rod (i) and a lever (h) mounted loose upon a shaft (a)
extending across the loom and the connecting rod (f) is connected by means of an
arm (c) and the shaft (a), an arm (d) and a connecting rod (e) to the shuttle-
boxes (9) at the other side of the loom. There being four shuttle-boxes at each
side of the loom illustrated by Figs. 5, 6, 7, 8 and 9 we employ in conjunction with
the connecting rod (1) two discs (m) (ml) and in conjunction with the connecting
rod (f) two discs (n) (n'). The discs (m) (¹) employed in conjunction with
the connecting rods (j) (f) respectively are respectively provided with
excentrics (28) (29) upon which are respectively mounted excentrics (30) (31)
which are embraced by excentric straps (40) (41) connected to the connecting
rods (j) (ƒ) respectively and are respectively provided with pins (30×) (31)
respectively engaging with slots (m*) (n) formed in the discs (m) (n) respectively,
as is illustrated in Figs. 5, 6, 7, 8, 9 and 10. In the arrangement illustrated in
Figs. 5, 6, 7, 8, 9 and 10 the discs (m) (m¹) (n) (n) are all mounted upon one stud
or axle (r). In conjunction with the pinions (tm) (t m¹), (tn) and (in') secured
to or formed upon the discs (m), (m²) (n) and (n) respectively, there are provided
four racks (um) (um') (un) (un) of which the racks (m) (un') are connected
by studs to arms (wm) (wn¹) formed upon a barrel (w') mounted fast upon an
axle (2) supported and capable of being oscillated in the bracket (g) and the
racks (um) (un) are connected by a stud to the arms (wm¹) (won) forming the
ends of a forked arm provided upon the said barrel (c). In conjunction with
the racks (um) (u m²) (un) (un¹) we employ darts or needles (m) (vm³) (vn) (vn³)
respectively and in conjunction with the darts or needles (vm) (m²) (vn) (un³) we
provide a pattern-chain-barrel (14) capable of being revolved in a frame or
lever (15) capable of being oscillated upon an axle (15) secured in the bracket (y).
The frame or lever (15) is oscillated by means of a cam (16) mounted fast upon
the crank-shaft (13) and secured in position thereon by means of a set screw.
Mounted fast upon the crank-shaft (13) and secured in position thereon by means
of a set screw is an excentric (y) embraced by a strap (32) connected to a
rod (32) embracing a stud (33) secured in the arm (wm) so that the revolution of
the excentric (y) causes the frame formed by the arms (w), barrel (w') and the
axle (2) to be oscillated and the racks (u) to be moved upwards and downwards.
The excentricity of the excentric (y) is such that if the rack (w) employed in
conjunction with either of the discs (m) (m²) (n) (n¹) be placed when in its highest
position in engagement with the pinion (t) in conjunction with which it acts and be
kept in engagement with such pinion (t) while being moved into its lowest position

page_text: the said pinion (t) will be turned through half a revolution in the direction
indicated by the arrow C. The cam (16) is so formed and secured upon the
crank-shaft (13) in such position in relation to the excentric (y) and the said
cam (16) and excentric (y) are so placed as to revolve in such relation to the
cranks upon the crank-shaft (13) which are employed to move the slay (27) that
when the loom is weaving the pattern-chain-barrel (14) shall be moved in the
direction indicated by the arrow (A) so as to cause the card or plate of the
pattern-card-chain (24) thereon which is presented to the darts or needles (v) if of
a character suitable to produce such an effect to move one or other of the darts or
needles (r) and press the rack (u) with which such dart or needle (v) is employed
into engagement with the pinion () in conjunction with which it is employed after
a pick or thread of weft has been laid across the warp being woven into a fabric
or cloth and before the slay (27) has moved forward to "beat up" such pick or
thread of weft so that during the succeeding half revolution of the crank-shaft (13)
the said rack (u) will turn the disc (m) (m³) (n) or (n) in conjunction with which
it is employed through half a revolution in the direction indicated by the arrow C
so as to have completed the required change in the position of the shuttle boxes
moved by means of such disc by the time at which the next pick or thread of weft
is required to be laid across the warp. The cam (16) is also formed so that the
racks (u) when pressed into engagement with the pinions () in conjunction with
which they are respectively employed will be kept in engagement therewith until
such pinions (1) have been moved through half a revolution by the action of the
excentric (y), and then allow such racks (u) to fall away from and out of engage-
ment with such pinions (t) and also permit the re-engagement with the discs upon which
such pinions are employed of the detents (25) which are provided in conjunction with
the discs, upon which such pinions (t) are employed and are mounted upon the
axle (25) supported in the bracket (9) and were moved out of engagement with
the said discs as the said racks (u) were pressed into engagement with the said
pinions (t) by means of the said darts or needles (v). In this arrangement as in
the arrangement illustrated in Figs. 1 and 2 the axle (w 2) of the barrel (w) is
provided with an arm (20) in which is secured a stud (20x) engaging with a slot,
formed in a lever (21) formed in two parts, one of which is adjustable in position
in relation to the other and is secured in position therein by means of a bolt and is
provided with two projecting studs (22) (23). The lever (21) is mounted upon an
axle (21) mounted so as to be capable of being oscillated in the bracket (7) and
capable of being slidden longitudinally as will be hereinafter described in order
that one or other of the said studs (22) (23) may be caused to turn the pattern-
chain-barrel (14) by acting respectively upon the notched wheel (18) mounted fast
upon the axle of the pattern-chain-barrel (14) or the notched wheel (19) mounted
so as to be capable of being rotated upon a stud secured in the lever or frame (15)
and provided with a toothed wheel gearing into another toothed wheel of equal
size mounted or formed upon the notched wheel (18). The excentricity of each
of the excentrics (28) (29) in relation to the axis of the disc by means of which it
is turned in the arrangement illustrated in Figs. 5, 6, 7, 8, 9 and 10 is such that if
such excentric (28) or (29) as the case may be, be turned through half a revolution
from or into the position in which it is indicated in Fig. 10 the shuttle-boxes (k)
or (9) in conjunction with which such excentric is employed will be raised or
lowered through a distance equal to that between the centre of one shuttle-box
and that adjacent to it. The excentricity of each of the excentrics (30) (31) in
relation to the excentric (28) or (29) on which it is mounted is such that if such
excentric (30) or (31) as the case may be, be turned through half a revolution by
the disc (m) or (n) as the case may be with which the projection on such excentric
engages being turned through half a revolution from or into the position in which
it is indicated in Fig. 10 the shuttle-boxes (k) or (y) in conjunction with which
such excentric (30) or (31) is employed will be raised or lowered through a
distance equal to twice the distance between the centre of one shuttle-box and that
adjacent to it.

page_text: Thus in the arrangement illustrated by Fig. 10 by one or other or both of the
discs employed in conjunction with each of the two connecting rods () () which
we provide at one side of the loom being turned from or into the position in which
it is indicated in Fig. 10 as may be requisite from time to time any one of the
shuttle-boxes in conjunction with which such connecting rod is employed may be
brought into position to deliver or receive a shuttle.
In the application of this part of our invention to a loom provided with three
rising and falling shuttle-boxes at each side we employ arrangements similar to
those which we have hereinbefore described as being employed in the application
of this part of our invention to looms provided with four rising and falling shuttle-
boxes at each side.
The application of this part of our invention to a loom provided with six rising
and falling shuttle-boxes at each side is illustrated by Fig. 11 of the accompanying
drawings, Fig. 11 being a section taken through a part of one form of the
mechanism employed in such application of this part of our invention on a plane
corresponding to that indicated by the line (D) (D) of Fig. 5.
In this application of this part of our invention we provide in conjunction with
the two connecting rods which we provide at one side of the loom six discs (m),
(m), (m2), (n), (n') and (n 2).
In the application of this part of our invention to a loom provided with six rising
and falling shuttle-boxes except in so far as it is requisite for the range of movement
of the connecting rods (j) (f) (i) (e) levers (h) and arms (c) (d) employed to
transmit motion from the mechanism employed to operate the rising and falling
shuttle-boxes to be adapted to the range of movement of the shuttle-boxes and the
employment of six discs (m) (m²) (m2) (n) (n¹) (n 2) requires the employment of
six darts or needles ("), six arms () and six racks (u) and a corresponding increase
in the length of each of the cards of the pattern-card-chain (24) and a corresponding
increase in the length of the pattern-chain-barrel (14) and a corresponding increase
in the width of the bracket (q) and frame or lever (15) and other corresponding
changes in the length and width of various parts of the apparatus employed, the
mechanism which is employed in conjunction with the discs (m) (m³) (m2) (n)
(n) (n 2) is similar to that illustrated in Figs. 5, 6, 7, 8, 9 and 10 as being employed in
conjunction with the discs (m) (m²) (n) (n) illustrated in such figures as employed
in the application of this part of our invention to a loon provided with four rising
and falling shuttle-boxes at each side. We shall therefore in the description of
the application of this part of our invention to a loom provided with six rising and
falling shuttle-boxes at each side confine ourselves as much as possible to a
description of the six discs (m) (m²) (m2) (n) (n¹) (n 2) employed and the parts
more intimately connected therewith.
In the arrangement illustrated in Fig. 11 the discs (m) (m') (m2) (n) (n²) (n2)
are all mounted upon an axle (r) mounted in the bracket (9) and the discs (m) (n)
are formed with bosses into which sleeves (m* *) (n**) capable of being revolved
upon the axle (r) and respectively formed upon excentrics (34) (35) and forming
axles for the discs (m²) (¹) respectively are respectively secured after the
discs (m) (n') have been respectively placed in position upon such
sleeves (m**) (***). The excentricity of each of the excentrics (34) (35) in
relation to the axle (r) is such that if it be turned through half a revolution from
or into the position in which it is illustrated in Fig. 11 the connecting rod (j)
or () in conjunction with which such excentric (34) or (35) is employed will be
lowered or raised through such a distance that the shuttle-boxes (k) or (g) moved
by means of such connecting rod (;) or (✓) will be raised or lowered through a
distance equal to the distance between the centre of one shuttle-box and the centre
of the shutile-box adjacent to it. Upon the excentrics (34) (35) are mounted
excentrics (36) (37) respectively which are respectively provided with pro-
jections (36) (37) respectively engaging with slots (mix) (n¹×) formed in the
discs (m) (n) respectively so that by the discs (m¹) (n¹) being turned the
excentrics (36) (37) may be turned upon the excentrics (34) (35) respectively.

page_text: The excentricity of each of the excentrics (36) (37) in relation to the centre of
the excentric (34) (35) on which it is mounted is such that if the said excentric (36).
or (37) be turned by the disc (m') or (n') as the case may be being turned through
hall a revolution from or into the position in which it is indicated in Fig. 11, the
shuttle-boxes moved by means of the connecting-rod () or (1) as the case may be
which is employed in conjunction with the said excentric will be raised or lowered
through a distance equal to that between the centre of one shuttle-box and the
centre of the shuttle-box adjacent to it. Upon the excentrics (36) (37) are
mounted excentrics (38) (39) respectively which are respectively provided with
projections (38) (39*) respectively engaging with slots (m2) (2×) formed in
the discs (m2) (2) respectively which are capable of being revolve: upon the
axle (r). The excentricity of each of the excentrics (38) (39) relative to the
centre of the excentric on which it is mounted is such that if the said excentric (38)
or (39) be turned by the disc (m2) (n2) as the case may be being turned through
half a revolution from or into the position in which it is indicated in Fig. 11 the
shuttle-boxes (k) or (g) moved by means of the connecting rod (j) or (1) as the
case may be which is connected to the strap (40) or (41) as the case may be
surrounding such excentric (38) or (39) will be raised or lowered through a
distance equal to twice the distance between the centre of one shuttle-box and the
centre of the shuttle-box adjacent to it.
By one or more or all of the discs (m) (m²) (m2) (n) (n³) (n2) employed in the
arrangement illustrated in Fig. 11, being turned either into the position in which
it or they is or are shown in Fig. 11 or into the position in which it or they would
be brought by being turned through half a revolution from the position in which
it or they is or are indicated in Fig. 11 the rising and falling shuttle-boxes at one
or other or both sides of the loom may be moved as may be requisite from time to
time.
In the application of this part of our invention to a loom provided with five rising
and falling shuttle-boxes at each side we employ arrangements similar to those
which we have above described as being applied to looms provided with six rising
and falling shuttle-boxes at each side.
In the application of this part of our invention to a loom provided with seven or
eight rising and falling shuttle-boxes at each side there are employed arrangements
illustrated in Fig. 12 which like Fig. 11 is a section taken on a plane corresponding
to that indicated by the line D D, of Fig. 5. The arrangement illustrated in
Fig. 12 is similar to that illustrated in Fig. 11 except in that in the arrangement
illustrated in Fig. 12 the excentricities of the excentrics (36) (37) in relation to
the excentrics (34) (35) respectively are made such that by the excentrics (36) (37)
being turned by the discs (m²) (n') respectively being turned through half a
revolution from or into the positions in which they are indicated in the accompanying
drawings, the rising and falling shuttle-boxes (k) (g) moved by means of the
connecting rods (j) (ƒ) respectively shall be raised or lowered through a distance
equal to twice the distance between the centre of one shuttle-box and the centre of
the adjacent shuttle-box and the excentricities of the excentrics (38) (39) in
relation to the excentrics (36) (37) respectively are made such that by the
excentrics (38) (39) being turned by the discs (m2) (n 2) respectively being turned
through half a revolution from or into the position in which they are indicated in
the accompanying drawings the rising and falling shuttle-boxes (y) (k) moved by
means of the connecting rods (j) (f) respectively shall be raised or lowered through
a distance equal to four times the distance between the centre of one shuttle-box
and the centre of the adjacent shuttle-box.
This part of our invention may be applied to looms arranged to work or to be
capable of working "pick and pick" so that two or more shuttles according to the
number of shuttle boxes provided may be delivered successively from the shuttle-
boxes at one side of the loom and when this part of our invention is so applied we
provide a needle or dart to be acted upon by the pattern-chain in order that the
picking may take place from one side of the loom twice or three or more times in

page_text: succession according to the number of shuttle-boxes or alternately from each side
of the loom as may be necessary or desirable from time to time.
When this part
of our invention is applied to a loom which may at any time be required to work
"pick and pick "the mechanism by which the movements of the shuttle-boxes at
the two sides of the loom are effected and controlled must be so arranged that
whenever it may be requisite the shuttle-boxes at both sides of the loom shall be
moved simultaneously though not necessarily always in the same direction or
always in opposite directions.
One mode of applying this part of our invention to a loom arranged to work or
to be capable of working "pick and pick "is illustrated in Figs. 5, 6, 7, 8, 9, 13, 14
and 15 of the accompanying drawings, Fig. 13 being a side elevation of a part of
that which is shown in Figs. 5, 6, 7, 8 and 9 seen from the direction of the right
hand of Fig. 5 and Figs. 14 and 15 elevations of a part of one of the picking shafts
employed in the loom, and the picking bowl carried thereby and the arm or finger
on which such bowl is mounted. In Figs. 6 and 7, (42) (43) are the tappets by
which the driving of the shuttles from side to side of the loom is effected. The
tappets (42) (43) are mounted fast upon the tappet-shaft which in the loon
illustrated in Figs. 5, 6, and 7 is made to revolve at the same speed as the crank-
shaft (13) by means of the wheels (¹) (= 2) mounted fast upon the crank-shaft (13)
and fast upon the tappet-shaft (-) respectively. The picking bowls (45) (46)
employed in conjunction with the tappets (42) (43) respectively are respectively
mounted upon arms or fingers (45) (46) which are respectively mounted upon
studs (45) (46) which are respectively mounted in the picking-shafts (47) (48).
The picking shafts (47) (48) are only indicated in Figs. 6 7 14 and 15 of the
accompanying drawings and are only shown in part in such figures, the picking-
sticks and the other parts of the picking-shafts being omitted from the accompanying
drawings as unnecessary for the illustration of our invention. The picking-
shafts (47) (48) are respectively mounted in bearings respectively secured to the
side-frames (b) (b) of the loom. The arms or fingers (45) (46) are respectively
provided with fingers (45°) (46°) projecting downwards and formed so as to bear
against the lower parts of the picking shafts (47) (48) respectively when the
bowls (45) (46) upon such fingers or arms (45°) (46) are in position to be
respectively acted upon by the tappets (42) (43) in conjunction with which they
are respectively employed and so prevent such fingers or arms (45°) (46°) from
being turned downwards by the blows given to them by the said tappets (42) (43).
The fingers (45) (46) of the arms or fingers (45) (46) are respectively provided
with projections (45) (46) which when the arms or fingers (45°) (46°) are in
position for the bowls (45) (46) to be acted upon by the tappets (42) (43) are
respectively in the paths in which the upper ends of levers (49) (50) respectively
capable of being oscillated upon studs (49) (50) secured in brackets secured to the
side-frames (b) (b) are capable of being moved so that by the levers (49) (50)
being turned and caused to bear upon the projections (454) (46) respectively the
arms or fingers (45") (46) may respectively be turned into positions in which the
bowls (45) (46) thereof will not be acted upon by the tappets (42) (43) respectively.
The levers (49) (50) are so connected together by a rod (51) extending across the
loom that when one of such levers (49) (50) is moved to turn the arm or finger (45")
or (46) with which it is employed so as to prevent the bowl (45) or (46) thereon
from being acted upon by the tappet (42) or (43) employed therewith the
other of such levers (49) or (50) shall be withdrawn from the arm or finger (45)
or (46) with which it is employed so as to allow the bowl (45) or (46) thereon to fall
into a position in which it can be acted upon by the tappet (42) or (43) in conjunction
with which it is employed. The lever (49) is provided with an arm (49) to which
is connected a connecting rod (52) which embraces a crank-pin (53) secured in a
dise (53) provided with two flat parts upon its edge and formed upon a pinion (53)
capable of being revolved upon a stud (54) secured in the bracket (y). A rack (55) is
provided to act in conjunction with the pinion (53). The rack (55) is mounted upon a
stud (55) secured in the lever (wn) and is so shaped that it will tend to turn

page_text: In the
away from the pinion (53) when not pressed into engagement therewith.
bracket (y) is mounted a dart or needle (55) which is provided with a finger (55)
projecting behind the rack (55) and serving to bring the rack (55) into engagement
with the pinion (53) and is adapted to be moved in order to cause the engagement
of the rack (55) with the pinion (53) by means of such cards of the pattern-card-
chain (24) as are not formed with holes at the parts presented to the dart or
needle (55) in the movement of the pattern-chain-barrel (14) in the direction
indicated by the arrow (A). The rack (55) is mounted in such position upon the
lever (won) that if such rack (55) be brought into engagement with the pinion (53)
when in its highest position and kept in engagement therewith while being moved
to its lowest position it will cause the pinion (53) to be turned through half a
revolution. The flat parts upon the edge of the disc (53) are formed in such
positions on such disc (53) that a spring (55) secured to the bracket (g) and
bearing against the disc (53) will retain the pinion (53) in the positions into
which it is moved by the rack (55) and ensure that after such pinion (53) has been
turned by means of the rack (55) the crank-pin (53) shall remain either in its
lowest position as is indicated in Figs. 5 and 13 or in its highest position as
indicated in Fig. 6. From the preceding description it is obvious that the upward
and downward movements of the rack (55) will take place simultaneously with the
upward and downward movements of the racks (u) so that when the presentation
of a card or plate of the pattern-card-chain (24) to the darts or needles (v) (55º)
causes a movement of the dart or needle (55) as well as a movement of one or
other of the darts or needles (v) the change in the position of the crank-pin (53)
caused by the action of such card or plate of the pattern-card-chain (24) upon the
dart or needle (55) bringing the rack (55) into engagement with the pinion (53)
will take place simultaneously with the change in the position of the shuttle-hoxes
caused by the action of the said card or plate of the pattern-card-chain (24) acting
upon the said needle or dart or needles or darts (e). The turning of the crank-
pin (52) causing the connecting rod (52) to be moved moves the levers (49) (50)
and causes the levers (49) (50) to move the fingers or arms (45) (46) and the
bowls (45) (46) thereon or allow them to be moved by their own weight. If the
crank-pin (53) is allowed to remain in its lowest position motion will be imparted
by the tappet (43) to the picking-bowl (46) at the right-hand-side of the loom in
each revolution of the crank-shaft (13) and if the crank-pin (53) is allowed to
remain in its highest position motion will be imparted by the tappet (42) to the
picking-bowl (45) at the left-hand side of the loom in each revolution of the crank-
shaft (13) and if successive movements of the pattern-chain-barrel (14) in the
direction indicated by the arrow (A) cause the dart or needle (55b) to be moved in
the direction indicated by the arrow (A) and so cause the crank-pin (53) to be
raised into its highest position and lowered into its lowest position in successive
revolutions of the crank-shaft (13) of the loom the picking sticks of the loom will
be moved alternately so that picks will be made from the left-hand side and the
right-hand side of the loom alternately. The pattern-card-chain (24) may thus by
being provided with cards or plates arranged in suitable order he made to cause
picking to take place as may be necessary or desirable either from each side of
the loom alternately as in the ordinary way of weaving or two or more times in
succession from either side of the loom as in what is termed "pick and pick'
weaving.
"
Studs (47) (48) are provided in the picking-shafts (47) (48) respectively in
order to prevent the fingers or arins (45°) (46) from being turned so as to raise
the bowls (45) (46) too high and upon the picking shafts (47) (48) there are
provided stops (47) (48) to act in conjunction with the side-frames () () of the
loom and prevent the bowls (45) (46) respectively from being brought by the action
of the springs employed in conjunction with the picking-shafts (47) (48) into
contact with any parts of the tappets (42) (43) other than the projecting
parts (42) (43) thereof which acting upon the said bowls (45) (46) effect the
picking. Although the loom illustrated in Figs. 1 and 2 of the accompanying

page_text: drawings is not arranged to work "pick and pick" at any time the tappet shaft (2)
of such loom being arranged to revolve at one half the speed of the crank-
shaft (13) of such loom the arrangements for enabling a loom to work "pick and
pick when it is requisite or desirable for such loom to so work which are
illustrated in Figs. 5, 6, 7, 8, 9, 13 14 and 15 of the accompanying drawings are
applicable either to looms similar to that illustrated in Figs. 1 and 2 which is
provided with two rising and falling shuttle-boxes at each side or to looms similar
to those provided with tive, six, seven or eight rising and falling shuttle-boxes at
each side which have been herein before described in reference to Fig. 11 and
Fig. 12 as well as to looms provided with three or four rising and falling shuttle-
boxes at each side as herein before described in reference to Figs. 5, 6, 7, 8, 9,
and 10 if the tappet-shafts of such looms be made to revolve at the same speed as
the crank-shafts of such looms. In cases in which "pick and pick" working is
unnecessary the loom illustrated by Figs. 5, 6, 7, and 9 of the accompanying
drawings may be arranged so that shuttles shall always be delivered alternately
from each side of such loom. It is obvious that in the use of the above described
arrangements for enabling the loom to work pick and pick " when it is requisite
or desirable that it should so work, the pattern-card-chain (24) employed must be
arranged in accordance with the number of shuttle-boxes at each side of the loom
and be so arranged that when the loom is made to work "pick and pick" from
either side the shuttle-boxes at both sides of the loom shall be moved so that each
shuttle propelled from a shuttle-box at one side of the loom shall be received in a
shuttle-box at the other side of the loom.
6:
Instead of the herein before described arrangements for enabling a loom to which
this part of our invention is to be applied to work "pick and pick" there may be
employed any other suitable arrangements by means of which such loom may be
arranged to work or be capable of working "pick and pick." In cases in which it
is not requisite to employ the arrangements illustrated in Figs. 1, 5, 6, 7, 8 and 9
and to be hereinafter further described which enable the pattern-card-chain (24) to
be made to revolve forwards or to cease revolving or to revolve backwards the
arms (20) and (21) and the notched wheel (19) and the toothed wheels upon the
notched wheels (18) and (19) may be dispensed with and upon the axle (w2) there
may be mounted as is indicated by dotted lines in Fig. 8 an arm (3) provided
with a stud to act upon and turn the notched wheel (18) in a manner analogous to
that in which the arm (21) and stud (22) in the arrangements shown in Figs. 1, 5, 8
and 9 turn such uotched wheel (18) and turn the pattern-chain-barrel (14) forwards
while the loom is weaving and backwards when the loom is turned backwards for
unweaving or any other purpose and so keep the pattern-card-chain (24) and
shuttle-boxes in proper relation to the pattern of the "piece" or cloth being
woven in the loom. Instead of the crauk (y) and cam (16) mounted so as to be
capable of being revolved upon the tappet-shaft (-) in the arrangement illustrated
in Fig. 1 of the accompanying drawings there may be employed an arrangement of
excentric (y) and cam (16) mounted fast upon the crank-shaft (13) of the loom as
in the arrangement illustrated in Figs. 5, 6, 7, 8 and 9 and instead of the
excentric (y) and cam (16) mounted fast upon the crank-shaft (13) as in the
arrangement illustrated in Figs. 5, 6, 7, 8 and 9 there may be employed an arrange-
ment of crank (y) and cam (16) mounted loose upon the tappet-shaft (2) as in the
arrangement illustrated in Fig. 1. We prefer however to employ the arrangements
of excentric (y) and cam (16) mounted fast upon the crank-shaft (13) of the loom
as when such arrangement is employed the apparatus which we employ is rendered
simpler and more compact than it can be made in cases in which as in the loom
illustrated in Fig. 1 the arrangement of crank (y) and cam (16) capable of being
revolved upon the tappet-shaft () is employed.
The arrangements herein before described in reference to this part of our inven-
tion enabling the shuttle-boxes at both sides of a loom to which this part of our
invention is employed to be readily moved in any manner which may be requisite
aud enabling a change in the position of the shuttle-boxes at either side of the loom

page_text: to be made in each of any desired number of successive revolutions of the crank-
shaft of the loom cuabling the requisite correspondence between the move nents of
the shuttle-boxes and the movements of the shuttles and the pattern of the cloth or
fabric being woven to be readily preserved and in cases in which arrangements are
nade for the loom to work "pick and pick" when it is desirable that such loom
should so work enabling the picking apparatus to be kept in proper relation to the
pattern of the cloth or fabric heing woven to be readily maintained render the
rorking of looms provided with rising and falling shuttle-boxes at each side more
efficient and convenient than the working of looms of such kind as hitherto
constructed and facilitate the production of such woven fabrics formed by inter-
weaving with warp two or more kinds of weft as require in any parts, single or any
odd number of weft-threads of any one kind.
"
In the case of looms which are not arranged to at times work "pick and pick
the arrangements for operating the rising and falling shuttle-boxes of loomis
provided with rising and falling shuttle-boxes at each side which are illustrated
in the accompanying drawings and are described in reference to this part of our
invention are also advantageous in that the pattern-card-chains (24) controlling
the movements of the shuttle-boxes are composed of cards or plates and thus much
simpler and more convenient to build up and manipulate than pattern-chains made
of rollers threaded on bars such as are employed in some of the arrangements of
looms with rising and falling shuttle-boxes at each side which have been heretofore
constructed, and in that they enable the looms to which they are applied to be
worked at a greater speed than is possible with the arrangements hitherto
employed.
A further part of our invention relates to looms for weaving in which there are
rising and falling shuttle-boxes at each side and consists in arrangements by means
of which the pattern-chains employed to act upon the darts or needles in looms of
the said kind to which are applied the arrangements of discs and cranks or
excentrics which have been hereinbefore described may be caused to be revolved
forwards or to cease revolving or to be revolved backwards. According to this
part of our invention we mount upon the pattern-chain-barrel upon which is
mounted the pattern-chain employed to act upon the darts or needles of a loom to
which this part of our invention is to be applied a wheel or equivalent device and
provide a second wheel or equivalent device connected to the said pattern-chain-
barrel by suitable gearing so that one of such wheels or equivalent devices may be.
employed to revolve the said pattern-chain-barrel in a direction contrary to that in:
which the other of such wheels or equivalent devices would revolve such pattern-
chain-barrel and we provide an arm provided with two studs to act upon the said
wheels or equivalent devices so that one or other of the said wheels or equivalent
devices may be employed to revolve the said pattern-chain-barrel as may be
necessary or desirable from time to time and in order that one or other of the said
studs or other devices provided for the purpose may be caused to act upon the
wheel or equivalent device in conjunction with which it is employed or so that both
of such studs or other devices may be placed out of action we provide a supple-
mentary or controlling pattern-chain which may conveniently be in the form
of a lag-chain with lags of three different heights and cause such supplementary or
controlling pattern-chain to bring one or other of the said studs or other devices
into position to be made to act upon the wheel or equivalent device in conjunction
with which it is employed or to place both of such studs or other devices out of
action. In order that the said supplementary or controlling pattern-chain may be
caused to revolve or cease revolving for a time as may be necessary or desirable we
mount such supplementary or controlling pattern-chain upon a pattern-chain-barrel
to which motion may be imparted by means of a rack moved at the same time and
by the same means as the racks above described as being employed to impart
motion to the discs above described and provide a dart or needle to bring the said
rack into gear and cause such dart or needle to be acted upon from time to time by
means of the pattern-chain employed to control the movements of the shuttle-boxes

page_text: or by means of supplementary cards attached at the requisite parts to such pattern-
chain. In some cases we may dispense with means for enabling the pattern-chain
controlling the movement of the shuttle-boxes to control the movement of the
supplementary or controlling pattern-chain.
This part of our invention is illustrated in Figs. 1, 5, 6, 7, 8 and 9 of the
accompanying drawings and as such figures have already been herein in great part
described in reference to the former part of our invention we shall now only
further describe such figures in so far as is necessary for the description of this
part of our invention.
To the axle (21%) upon which the lever (21) is secured there is secured an
arm (56) formed with a slot into which projects a finger (57") secured to a bell-
crank-lever (57) capable of being oscillated upon a stud (57) secured in the
bracket (g) and provided with a finger (57) which rests upon the links of a
lag-chain (58) supported by a lag-barrel (59) mounted and capable of being
revolved upon a stud (60) secured in the bracket (g). A dart or needle (61)
capable of being slidden to and fro in the bracket (g) is provided with a
finger (61) which projects behind a rack (62) mounted upon a stud (62) secured
in the lever (rm) in such position that if such rack (62) when in its highest
position is pressed into engagement with a pinion (63) formed upon the lag-
barrel (59) and kept in engagement therewith while being moved to its lowest
position such rack (62) will cause such pinion (63) and lag-barrel (59) to be
turned through one sixth of a revolution in the direction indicated by the arrow F.
The rack (62) is so formed that it shall tend to turn upon the stud (62) upon
which it is mounted and fall and remain away from and cut of gear with the
pinion (63) except when pressed into engagement therewith. When the movement
of the pattern-chain-barrel (14) in the direction indicated by the arrow (A)
presents to the dart or needle (61) a card capable of moving such dart or
needle (61) at which times the said dart or needle (61) being moved in the direction
indicated by the arrow (A) causes the rack (62) to be pressed into engagement
with the pinion (63) and then the rack (62) being moved simultaneously with the
racks (u) will turn the lag-barrel (59) through one-sixth of a revolution and bring
another lag of the lag-chain (58) beneath the finger (57) of the bell-crank-
lever (57), a plate spring (59) secured to the bracket (y) and bearing against a
hexagonal disc (59) formed on the lag-barrel (59) holds such lag-barrel (59) in
the positions into which it is turned. The lag-chain (58) may be provided with
lags of three heights, the lags (58) of the greatest height when brought beneath
the finger (57) bringing or holding the stud (22) of the lever (21) into or in
position to turn the notched wheel (18), the lags (58) of the least height when
brought beneath the finger (57) allowing the weight of such finger (57) to turn
or hold the bell-crank-lever (57) into or in position to hold the axle (21) in such
position that the stud (23) of the lever (21) may turn the notched wheel (19),
while the lags (58) of medium thickness when brought beneath the finger (57)
turn or allow the turning of or hold the bell-crank-lever (57) into or in position to
move or hold the axle (21%) into or in such position that neither of the
studs (22) (23) of the lever (21) shall be capable of acting upon the notched
wheels (18) (19) in conjunction with which they are respectively employed.
While the loom is weaving if motion be imparted to the pattern-card-chain (2+)
by the stud (22) turning the notched wheel (18) the pattern-card-chain (24) will
be caused to revolve in the direction indicated by the arrow G, and if motion be
imparted to the pattern-card-chain (24) by the stud (23) turning the notched
wheel (19) the pattern-card-chain (24) will be caused to revolve in the direction
opposite to that indicated by the arrow G. Thus by the lag-chain (58) being
provided with lags of the kinds requisite the pattern-card-chain (24) may be
caused to revolve forwards, cease revolving or revolve backwards from time to
time as may be requisite and the pattern-card-chain (24) being provided at the
requisite parts with cards adapted to act upon the dart or needle (61) the
movements of the lag-chain (58) may be caused to take place at the interval

page_text: requisite and thus by the use of a lag-chain (58) and pattern-card-chain (24)
suitably arranged, long patterns in which several or a considerable number of
picks or threads of weft of one kind require to be woven or laid in succession into
the cloth or fabric being woven, or patterns requiring to be woven first in one
order and then in a reverse order may be woven by means of comparatively short
pattern-card-chains. While the loon is weaving the turning of the lag-barrel (59)
by means of the rack (62) takes place while the pattern-chain-barrel (14) is in the
position iuto which it is brought at the end of its movement in the direction
indicated by the arrow (A) and consequently if a lag (58) of the intermediate
height be brought beneath the finger (57) so as to prevent the pattern-chain-
barrel (14) from being turned at the end of its succeeding movement in the
direction opposite to that indicated by the arrow (A) the next movement of
the pattern-chain-barrel (14) in the direction indicated by the arrow (A) will
cause the dart or needle (61) to be again moved and cause the lag-barrel (59) to
be again turned. When the loom is turned backwards for unweaving the pattern-
card-chain (24) and lag-chain (58) and the shuttle-boxes will be kept in proper
relation to the pattern of the piece or cloth being woven in the loom as the parts
by means of which such pattern-card-chain (24) and lag-chain (58) and shuttle-
boxes are moved operate at such times in a manner precisely the reverse of that in
which they operate while the loom is weaving.
The change in the position of the lever (21) requisite to effect a change in the
direction of the revolution of the pattern-card-chain (24) which change in the
position of the lever (21) is brought about by the presentation to the needles or
darts (v), (61) of a card or plate of such pattern-card-chain (24) is caused to take
place while the pattern-chain-barrel (14) is kept in the position in which it is at
the end of its movement in the direction indicated by the arrow (A) and simulta-
neously with the change if any in the position of the shuttle-boxes caused by the
said plate or card, and after the said change in the position of the lever (21) bas
been brought about and before the pattern-chain-barrel (14) is again moved in the
direction indicated by the arrow (A) the said lever (21) is caused to turn the said
pattern-chain-barrel (14) in a direction opposite to that in which it was last turned
and bring into position to be presented to the darts or needle (e) (61) the card or
plate of the pattern-card-chain (24) adjacent to the card or plate which brought
about the said change in the position of the lever (21). Thus so long as the action
of the pattern-card-chain (24) upon the dart or needle (61) causes a series of
lags (58) of greatest height or a series of lags (58) of least height or lags (58ª)
of greatest height and lags (58) of least height alternately to be brought beneath
the finger (57) the lever (21) will turn the pattern-chain-barrel (14) between
each movement of such pattern-chain-barrel (14) in the direction indicated by the
arrow (A) whether the turning of such pattern-chain-barrel (14) be in the direction
indicated by the arrow (G) or in the opposite direction or first in the direction
indicated by the arrow (G) and then in the opposite direction, and the reversal of
the direction of the revolution of the pattern-card-chain (24) may be effected on a
single pick at any time. If two adjacent cards or plates of the pattern-card-
chain (24) be both adapted to act upon the dart or needle (61) when presented to
the darts or needles (v) (61) and the lag-chain (58) be provided with a suitable
number of lags (58) of greatest height and lags (58) of least height placed
alternately and be so arranged that the one of the said two adjacent cards or plates
of the pattern-card-chain which first acts upon the dart or needle (61) brings
beneath the finger (57) either a lag (58) of greatest height or a lag (58) of
least height according as the lag which was previously beneath the finger (57)
was a lag (58) of greatest height or a lag (58°) of least height and that
the other of the said two adjacent cards or plates of the pattern-card-
chain (24) acting upon the dart or needle (61) brings beneath the finger (57º),
according as a lag (58) of greatest height or a lag (58) of least height was
previously beneath the finger (57), a lag (58) of least height or a lag (58) of
greatest height which forms the first of the said suitable number of lags (58") of

page_text: greatest height and lags (58) of least height placed alternately the said two
adjacent cards or plates of the pattern-card-chain (24) will be caused to be presented
alternately to the darts or needles (v) (61) until all the lags forming the said
suitable number of lags (58) of greatest height and lags (58) of least height
placed alternately have been brought beneath the finger (57).
The herein before described arrangement for effecting the reversal of the direction
of the revolution of the pattern-card-chain (24) thus enables the laying of a single
pick or thread or any odd number of picks or threads of weft of any one of the
kinds employed in the cloth or fabric being woven in the loom to be very readily
accomplished besides enabling comparatively short pattern-card-chains to serve for
the weaving of long patterns in which several or a considerable number of picks or
threads of weft of one kind require to be woven or laid in succession into the cloth
or fabric being woven or patterns requiring to be woven first in one order and then
in a reverse order. In order that no breakage or injury may occur to the looms
illustrated in the accompanying drawings should the shuttle-boxes thereof be
prevented from being moved when the connecting rods employed therewith receive
motion from the sets of mechanism or devices for moving shuttle-boxes to which
they are connected, the connecting rods (f) (j) (e) (i) employed in each loom
illustrated in the accompanying drawings are as is the case with the connecting
rods employed in many looms heretofore constructed, each arranged to be capable
of yielding in one direction and provided with springs to keep them from so
yielding in ordinary use; and in the looms illustrated in the accompanying
drawings as is the case in many looms heretofore constructed the weight of the
shuttle-boxes is counterbalanced or partially counterbalanced by the springs applied
to certain of the connecting rods employed."
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. In a loom provided with rising and falling shuttle-boxes at each side, the
combination of two connecting rods placed at one side of the loom and connected,
one by means of a lever to the shuttle-boxes at such side of the loom and the other
by means of arms or levers to a shaft extending across the loom and serving to
transmit to the shuttle-boxes at the other side of the loom the motion which it may
receive from the said connecting rod connected to it, discs such as are herein before
described to impart motion to the said connecting rods, racks to turn the said discs
separately or together by means of pinions provided upon such discs, detents to
hold the said discs in the positions into which they may be turned, means to move
the said racks, darts or needles to press the said racks into engagement with the
pinions in conjunction with which they are respectively employed a pattern-card-
chain to act upon the said darts or needles, a pattern-chain-barrel to support the
said pattern-card-chain, means to support the said pattern-chain-barrel and move
it so as to cause the cards or plates of the said pattern-card-chain to move the said
darts or needles and means to cause the said pattern-card-chain to revolve in one
direction while the loom is weaving, all arranged, employed and operating
substantially in the manner hereinbetore described in reference to Figs. 1, 2, 3,
and 4, Figs. 5, 6, 7, 8, and 9 and Fig. 10 Fig. 11 or Fig. 12 of the accompanying
drawings, and for the purposes of enabling the shuttle-boxes at both sides of the
loom to be readily operated by means of oue pattern-chain while enabling the
shuttle-boxes at each side of the loom to be moved independently of the shuttle-
boxes at the other side thereof and enabling fabrics requiring in any parts single
or any odd numbers of threads or picks of weft of any of the kinds employed to be
readily produced in the said loom.
2. In a loom provided with rising and falling shuttle-boxes at each side the
combination of two connecting rods placed at one side of the loom and connected,
one by means of a lever to the shuttle-boxes at such side of the loom and the other
by means of arms or levers to a shaft extending across the loom and serving to

receive from the said connecting rod, connected to it, discs such as are hereinbefore
described to impart motion to the said connecting rods, racks to turn the said discs
separately or together by means of pinions provided upon such discs, detents to
hold the said discs in the positions into which they may be turned, means to move
the said racks, darts or needles to press the said racks into engagement with the
pinions in conjunction with which they are respectively employed, a dart or needle
arranged to be capable of controlling the action of the mechanism by means of
which the picking or driving of shuttles across the loom is effected so as to enable-
picking to take place from each side of the loom alternately or twice or three or
more times in succession from either side of such loom as may be necessary or
desirable from time to time according to the number of shuttle-boxes provided, a
pattern-card-chain to act upon the said darts or needles, a pattern-chain-barrel to
support the said pattern-card-chain, means to support the said pattern-chain-barrel
and move it so as to cause the cards or plates of the said pattern-card-chain to
move the said darts or needles and means to cause the said pattern-card-chain to.
revolve in one direction while the loom is weaving, all arranged, employed and
operating substantially in the manner hereinbefore described in reference to.
Figs. 1, 2, 3 and 4, Figs. 5, 6, 7, 8 and 9 and Fig. 10, Fig. 11 or Fig. 12 of the-
accompanying drawings, and for the purposes of enabling the shuttle-boxes at both
sides of the loom to be readily operated by means of one pattern-chain while
enabling the shuttle-boxes at each side of the loom to be moved independently of
the shuttle-boxes at the other side thereof, and enabling fabrics requiring in any
parts single or any odd numbers of threads or picks of weft of any of the kinds.
employed to be readily produced in the said loom.
3. In a loom provided with rising and falling shuttle-boxes at each side the
combination of two connecting rods placed at one side of the loom and connected,
one by means of a lever to the shuttle-boxes at such side of the loom and the other
by means of arms or levers to a shaft extending across the loom and serving to.
transmit to the shuttle-boxes at the other side of the loom the motion which it may
receive from the said connecting rod connected to it, discs such as are hereinbefore
described to impart motion to the said connecting rods, racks to turn the said discs.
separately or together by means of pinions provided upon such discs, detents to.
hold the said discs in the positions into which they may be turned, means to move
the said racks, darts or needles to press the said racks into engagement with the
pinions in conjunction with which they are respectively employed, a pattern-card-
chain to act upon the said darts or needles, a pattern-chain-barrel to support the
said pattern-card-chain, means to support the said pattern-chain-barrel and move it
so as to cause the cards or plates of the said pattern-card-chain to move the said.
darts or needles and the herein before described means which enable the said
pattern-card-chain to revolve forwards, cease revolving or revolve backwards as
may be necessary or desirable while the loom is weaving, and consist in the lag-
chain (58), lag-barrel (59), finger (57b), bell-crank-lever (57) arm (56) axle (21*).
lever (21) notched wheels (18) (19) respectively provided with pinions, rack (62)
