PROVISIONAL SPECIFICATION.
Improvements in certain Looms for Weaving in which what are
known as Rising and Falling Shuttle Boxes are employed.
I, FRIEDRICH HERMANN LUDWIG STELLING, of 1, Bennett Street, Crumpsall,
in the County of Lancaster, Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
My invention relates to such looms for weaving as are provided with what are
known as rising and falling shuttle boxes operated by arrangements of cranks, cams
or excentrics in which the shuttle boxes are brought into the various necessary
positions by changes being made in the relative positions of the cranks, cams or
excentrics.
Hitherto to operate the cranks, cams or excentrics above mentioned it has been
customary to employ arrangements of apparatus in which although the pattern
chain employed was composed of cards or plates or other appliances of different
characters the cards or plates or other appliances of one character did not always
cause one shuttle box and that only, to be brought into position for delivering or
receiving a shuttle but on the contrary the effect produced by a certain card or
plate or other appliance being presented to the darts or needles or other devices
employed in conjunction with the cranks, cams or excentrics depended upon the
position occupied by the shuttle boxes when the said card or plate or other appliance
was presented to the darts or needles or other devices.
My invention consists in methods and arrangements by means of which each card
or plate or other suitable appliance of the pattern chain may be caused to bring
one shuttle box and one shuttle box only into position for delivering or receiving a
shuttle whatever may be the position of the shuttle boxes when the said card or
plate or appliance is presented to the darts or needles or other devices by means of
which the cards or plates or other appliances cause or control the movements of the
shuttle boxes.
According to the first part of my invention I cause each of the darts or needles
employed in conjunction with the cranks, cams or excentrics above mentioned to so
move when acted upon by a card or plate or other appliance of the pattern chain
that if another like card or plate or appliance be presented to such needles or darts
or other devices the needle or dart or device previously acted upon will pass into
a hole formed in the card or plate or appliance or otherwise fail to be acted upon
by such card, plate or appliance. The movement of each dart or needle or other
device is so arranged that while in each of the positions into which, the said dart or
needle or device may be moved in accordance with this part of my invention such
needle or dart or device will fail to be acted upon by certain cards or plates or other
appliances of the pattern chain such needle or dart or device will at such times be
in position to be acted upon by other cards or plates or other appliances of the
pattern chain. By so causing the position of each dat or needle or other device
to be changed whenever snch dart or needle or other device is acted upon by a card
or plate or other appliance of the pattern chain I am enabled to arrange that a
card plate or other appliance of one pattern or character will always bring a
certain shuttle box and only that one into position for delivering or receiving
a shuttle whatever may be the position of the shuttle boxes when the said card or
plate or appliance is presented to the darts or needles or other devices.
A further part of my invention consists in arrangements by means of which I
cause each of the needles or darts or other devices above mentioned to move as
above described when acted upon by a plate or card or other appliance of the
pattern chain. According to this part of my invention I form upon any suitable
part which revolves or moves at the time when a change in the position of the

page_text: shuttle boxes takes place, a suitable cam which I cause to act by suitable means
and in any suitable manner upon the dart or needle or device which has by
being acted upon by the card or plate or appliance of the pattern chain brought
about such change of position of the shuttle boxes so that such dart or needle
will be moved or turned vertically or horizontally or in any other suitable
direction into a position in which it would fail to be operated upon by a card
or plate or appliance similar in so far as concerns the part which would operate
upon the said needle or dart or device to that which last operated upon it. A
similar arrangement or similar arrangements is or are employed in conjunction
with the other needle or dart or device or the other needles or darts or devices
employed in the loom to which this portion of my invention is applied.
A further part of my invention also consists in arrangements by means of
which I cause each of the needles or darts or other devices above mentioned to
move as above described when acted upon by a plate or card or other appliance
of the pattern chain. According to this part of my invention I employ in con-
junction with each dart or needle or other device employed to operate the cranks
cams or excentrics by means of which the shuttle boxes are moved a disc wheel
or part provided with cams or wipers or other suitable devices and arranged to
be moved or turned either by the dart or needle or other device or by other
suitable means each time that the said dart or needle or other device is operated
upon by a card or plate or other appliance of the pattern chain. The disc,
wheel or part in moving is caused to act upon the dart or needle or other
device so as to move it into a position in which a card or plate or other appliance
similar to that which last acted upon it in so far as regards the part intended
to act upon such dart or needle or other device will fail to act upon the said
dart or needle. The disc, wheel or part employed in conjunction with each
needle or dart or other device may be secured to or connected by means of
gearing or other suitable means with the discs, wheels or parts employed in
conjunction with the other needle or dart or other device or the other needles or
darts or other devices so that the movement of one of the said discs, wheels or parts
will result in a movement of each of the other discs, wheels or parts and may
result in a movement of the other needle or dart or device or needles or darts or
devices in a manner similar to that above described.
A further part of my invention also consists in arrangements by means of
which I cause each of the needles or darts or other devices above mentioned to
move as above described when acted upon by a plate or card or other appliance
of the pattern chain.
According to this part of my invention I provide in conjunction with each of
the darts or needles employed to actuate the cranks cams or excentrics employed
to operate the shuttle boxes of the loom to which this part of my invention is
applied a sleeve or part capable of being turned or moved in a direction perpen-
dicular to the length of the said needle dart or device and provided at each end
with suitable teeth or projecting or other parts adapted to act in conjunction
with other teeth or projecting or other parts of suitable form provided upon
suitable parts in such manner that the said sleeve or part will be moved in
relation to the said dart or needle or device or turned at each movement of such
sleeve or part in the direction of its length. The said sleeve or part may be
moved by the card or plate or other appliance of the pattern chain which is to
act upon the said dart or needle or by any other suitable means. The said
sleeve or part may be provided either with a part to act as a cam in order to
move the dart or needle into or out of position for being acted upon by the
appropriate portions of the cards or plates or other appliances of the pattern
chain or the said sleeve or part may be provided with a part which may at
times be acted upon by the required portions of the cards or plates or other
appliances of the pattern chain and may at other times by being moved into
another position fail to be acted upon by the said cards, plates or other
appliances.

page_text: A further part of my invention also consists in arrangements by means of
which I cause each of the darts or needles or other devices above mentioned
to move as above described when acted upon by a plate or card or other appliance
of the pattern chain. According to this part of my invention I provide in con-
junction with each dart or needle or other device to which this part of my
invention is to be applied a projection or guide arranged to turn or move to a
suitable extent in regard to the part by which it is supported and moved or
turned either by means of the dart or needle or other device with which it is
employed or in any other suitable manner so that whenever the said dart or
needle or other device is acted upon by a card or plate or other appliance of
the pattern chain such dart or needle or other device will be so guided on
returning to its normal position that it will occupy a position different from that
which it occupied before it was acted upon by the said card or plate or appliance.
A further part of my invention consists in arrangements by means of which
the needles or darts or other devices by means of which the cranks, cams or
excentrics above referred to are caused to move the shuttle boxes into the various
required positions may each be caused to be actuated by one of two needles or
darts or like devices which are acted upon by one of the cards or plates or other
appliances of the pattern chain and are caused to move so that when one of such
needles or darts or like devices has acted upon the dart or needle or device to act
upon the crank cam or excentric such dart or needle or like device will be moved
so that a card or plate or appliance similar in so far as its tendency to act upon the
dart or needle or like device is concerned to that which last acted upon the said
dart or needle or like device could cause such dart or needle or like device to be
moved it would not cause the dart or needle or device acting upon the cam, crank
or excentric to be moved. According to this part of my invention I provide in
conjunction with the dart or needle or device employed in conjunction with each
crank, cam or excentric a sleeve or part capable of being slidden longitudinally and
turned around or moved in a direction at right angles to that in which it is slidden
and arranged to be slidden longitudinally each time that the dart or needle or
device is moved to operate the crank, cam or excentric. The said sleeve or part is
provided at each end with suitable teeth or projecting parts or other devices which
are adapted to so act in conjunction with suitable teeth or projecting parts or other
devices formed or provided on suitable parts adjacent to the ends of the said sleeve
or part that such sleeve or part will be turned or moved in a direction at right
angles to that in which it is slidden at each movement which it is caused to make
in the direction of its length. The said sleeve or part may be moved in the
direction of its length either by the darts or needles or like devices upon which the
cards or plates or other appliances of the pattern chain act or by means of the dart
or needle or device which is caused to act upon the aforesaid crank, cam or
excentric or may be moved in the direction of its length in any other suitable
manner. The said sleeve or part may either be provided with parts to act as cams
to move the dart or needle or device which last caused the movement of the crank
cam or excentric aforesaid into such position that it will not again act upon the
said crank, cam or excentric until restored or allowed to return to its former position
by a further turning or movement of the said sleeve or part or may be provided
with a part which according to the position of the said sleeve or part will be in the
path of one or the other of the darts or needles or like devices employed to com-
municate motion to the darts or needles or devices causing the movement of the
crank, cam or excentric aforesaid. A sleeve or part similar to and operating
similarly to that above described is provided in conjunction with each of the cranks,
cams or excentrics employed in the loom to which this part of my invention is
applied.

Improvements in Certain Looms for Weaving in which what are
known as Rising and Falling Shuttle Boxes are employed.
I, FRIEDRICH HERMANN LUDWIG STELLING of 1. Bennett Street, Crumpsall
in the County of Lancaster, Engineer, 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 :-
My invention relates to such looms for weaving as are provided with what are
known as rising and falling shuttle boxes operated by arrangements of cranks, cams
or excentrics in which the shuttle boxes are brought into the various necessary
positions by changes being made in the relative positions of the cranks, cams or
excentrics.
In most of the arrangements hitherto employed although the pattern-chain
employed has been composed of cards or plates or other appliances of different
characters the cards or plates or other appliances of one character have not always
caused one shuttle-box and that only to be brought into position for delivering or
receiving a shuttle but on the contrary the effect produced by a certain card or
plate or other appliance being presented to the darts or needles or other devices
employed in conjunction with the cranks cams or excentrics depended upon the
position occupied by the shuttle-boxes when the said card or plate or other
appliance was presented to the darts or needles or other devices.
In other arrangements previously in use the cards or plates or other appliances
of one character in the pattern-chain employed to operate the cams, cranks or
excentrics above mentioned have caused one shuttle-box and that only to be
brought into position for receiving or delivering a shuttle but in such arrangements
it has been necessary to employ additional darts or needles or other devices besides
that or those which would be sufficient if it were not required that a card or plate
or other appliance of one character should always bring one shuttle-box and that
only into position for receiving or delivering a shuttle and the apparatus employed
has been complicated.
My invention consists in methods and arrangements by means of which, without
it being necessary to employ complicated apparatus or a greater number of darts
or needles or equivalent parts than would be necessary if it were immaterial
whether a card or plate or other appliance of one character in the pattern-chain
when presented to the darts or needles or other devices employed in conjunction
with the pattern-chain, did or did not always bring one shuttle box and that only
into position for receiving or delivering a shuttle, each card or plate or other suit-
able appliance of one character in the pattern-chain may be caused to bring one
shuttle-box and one shuttle-box only into position for delivering or receiving a
shuttle whatever may be the position of the shuttle-boxes when the said card or
plate or appliance is presented to the darts or needles or other devices by means of
which the cards or plates or other appliances cause or control the movements of the
shuttle-boxes.
According to the first part of my invention I cause each of the darts or needles
employed to receive motion from the cards or plates or other appliances of the
pattern-chain so as to cause or control the movements of the cranks, cams or
excentrics to so move when acted upon by a card or plate or other appliance of the
pattern-chain that if another like card or plate or appliance be presented to such
needles or darts or other devices the needle or dart or device previously acted upon
will pass into a hole formed in the card or plate or appliance or otherwise fail to be
acted upon by such card or plate or appliance. The movement of each dart or
needle or other device is so arranged that while in each of the positions into which
the said dart or needle or device may be moved in accordance with this part of my
invention such needle or dart or device will fail to be acted upon by certain cards
or plates or other appliances of the pattern-chain such needle or dart or device will

page_text: at such times be in position to be acted upon by other cards or plates or other
appliances of the pattern-chain. By so causing the position of each dart or needle
or other device to be changed whenever such dart or needle or other device is acted
upon by a card or plate or other appliance of the pattern-chain I am enabled to
arrange that a card, plate or other appliance of one character will always bring a
certain shuttle-box and only that one into position for delivering or receiving a
shuttle whatever may be the position of the shuttle-boxes when the said card or
plate or appliance is presented to the darts or needles or other devices.
In the accompanying drawings
Figs. 1, 2, 3, 4, 5, 6, 7, 8, and 9 are diagrams illustrative of this part of my
invention as applied to a loom provided with four rising and falling shuttle
boxes.
Figs. 1, 2, 3, and 4 illustrate the cards or plates which would be used in applying
this part of my invention to a loom provided with four rising and falling shuttle-
boxes.
Fig. 5 is a diagram indicating the position of the cranks, cams or excentrics a b
employed to actuate the shuttle-boxes when the first of the four rising and falling
shuttle-boxes with which the loom provided is in position to deliver or receive a
shuttle.
Fig. 6. is a diagram indicating the position of the cranks, cams or excentrics ab
when the second of the rising and falling shuttle-boxes is in position to deliver or
receive a shuttle.
Fig. 7 is a diagram indicating the position of the cranks, cams or excentrics ab
when the third rising and falling shuttle-box is in position to deliver or receive a
shuttle and
Fig. 8 is a diagram indicating the position of the said cranks, cams or excentrics a b
when the fourth rising and falling shuttle box is in position to deliver or receive a
shuttle.
Fig. 9 is a diagram of a portion of a chain constructed of cards or plates c d e f
such as are illustrated in Figs. 1, 2, 3 and 4 and serving to illustrate the manner in
which the movement of the needles or darts or other devices operated upon by the
said cards or plates in the manner above described enables the object of my
invention to be accomplished.
Fig. 10 is a diagram illustrating the principle upon which the cards or plates or
other appliances employed in carrying my invention into effect are constructed.
Although my invention is applicable to all kinds of looms in which rising
and falling shuttle-boxes operated by cranks, cams or excentrics are employed
I for convenience describe this part of my invention as applied to a loom such as
that described by James Cowburn and Christopher Peck in the Complete
Specification filed in respect of their application for Letters Patent No. 3544
dated February 28th, 1889 and accordingly I have in Figs. 5, 6, 7, and 8 of the
accompanying drawings shown diagrams of the discs and crank employed in the
arrangement described in the said Specification, but as my invention would apply
equally to other looms in which needles or darts or other devices are employed to
govern the movement of cranks, cams or excentrics effecting the movement of the
rising and falling shuttle-boxes I will in the description of this part of my invention
refer to the apparatus controlled or governed by each needle or dart or other
device as a crank, cam or excentric.
Each of the cards or plates which I employ is so arranged that each needle or
dart in conjunction with which it is employed may be acted upon by either of two
parts of such card or plate.
This is clearly illustrated in Fig. 10 which is a diagram of one card or plate
before any of the holes with which cards or plates when ready for use are provided
are formed therein. One of the darts or needles or other devices in conjunction
with which such card or plate is employed may be acted upon by the part A of the
card or plate or by the part B thereof according to the position in which the said
dart or needle or other device may be when the said card or plate is presented to it.

page_text: The other dart or needle or other device in conjunction with which the said card or
plate is employed may be acted upon by the part C of such card or plate or by the
part thereof. By a hole of a size suitable to allow the needle or dart or other
device to which it is presented to pass through it, being formed in one of the
parts A B of the card or plate aforesaid and in one of the parts C D thereof the
parts in which the holes are formed will be prevented from acting upon the needles
or darts or other devices should such needles or darts or other devices be opposite
to the holes when the card or plate is presented to such darts or needles or other
devices. If only one of the said darts or needles or other devices should be opposite
to a hole in the card or plate when such card or plate is presented to them that
dart or needle or other device only will remain unacted upon by the said card or
plate. In Figs. 1, 2, 3, and 4 are shown cards or plates cde and respectively
suitable for use in a loom in which two darts or needles or other devices are
employed to cause or control the movement of four rising and falling shuttle
boxes.
Each of the cards or plates c d e f illustrated in the diagrams Figs. 1, 2, 3
and 4 is provided with a hole in proximity to each of the parts of such card or
plate which are intended to act upon the darts or needles or other devices in
conjunction with which such card or plate is to be employed.
According to this part of my invention besides providing in each card or plate
employed two parts for presentation to each of the needles or darts or other devices
in conjunction with which the said card or plate is employed either of which parts
may be formed with a hole so that the needle or dart to which the said part is
presented may remain unacted upon I cause each of the darts or needles or other
devices to move when it has been acted upon by the part of a plate or card into
such position that its end will be opposite to the hole formed in proximity to the
said part h. If the said needle or dart or other device be so moved it follows that
if the next plate or card presented to such needle or dart or other device has the
part intended to act upon the needle or dart or other device and the hole g
adjacent thereto arranged in the same position in the plate or card, the end of the
said dart or needle or other device will pass into the hole g, in such plate or card,
and thus such dart or needle or other device will fail to be acted upon by the said
card or plate. If, however, the next card or plate presented to the dart or needle
or other device aforesaid, should have the part intended to act upon the dart or
needle or other device in such position, that it will act upon the said dart or needle
or other device while in the position in which it was last placed, the said dart or
needle or other device will be actuated thereby and then be moved so that its end
will be opposite to the hole adjacent to the said part of such card, so that a
similar card presented to the needle or dart or other device would fail to act upon
such needle or dart or other device. Although the foregoing description of this
part of my invention will enable the application of this part of my invention to be
readily understood, I will now further describe this part of any invention in reference
to Figs. 5. 6. 7. 8. and 9. of the accompanying drawings. As has been stated above,
the diagrams Figs. 5. 6. 7. and 8. indicate the various positions occupied by the
cranks, cams, or excentrics ab when the various shuttle-boxes are respectively in
position to receive or deliver a shuttle. In Fig. 5 both of the cranks, cams or
excentrics a. b. are turned upward, in Fig. 6. the crank a is turned upward, while
the crank is turned downward, in Fig. 7 the crank a is turned downward while
the crank is turned upward and in Fig. 8 the cranks a and b are both turned
downwards. If it be assumed that the cranks, cams or excentrics a and b are in
the position in which they are indicated in Fig. 5 and the needles or darts or other
devices, which control the movement of the said cranks cams, or excentrics a bare
respectively in the positions indicated by the circles j k drawn in full lines and
shaded above the cards or plates indicated in Fig. 9 the presentation to such needles
or darts or other devices of a plate or card d such, as is indicated in Fig. 2. will
cause the dart, needle or other device controlling the movement of the crank, cam
or excentric 6 to be moved into the position in which it is indicated in Fig. 6 while

page_text: the crank cam or excentric a will remain unmoved. In like manner the presentation
to the said needles darts or other devices, of a card or plate e such as is indicated
in Fig. 3 will cause the crank cam or excentric a to be turned into the position in
which it is indicated in Fig. 7 while the crank, cam or excentric & remains unmoved,
and the presentation to such needles or darts or other devices of a plate or card 1.
such as indicated in Fig. 4 will cause both of the cranks, cams, or excentrics ab to
be moved into the position in which they are indicated in Fig. 8. If the plates or
cards arranged in a chain as in the diagram, Fig. 9 are presented successively to
the darts or needles or other devices controlling the movement of the cranks, cams,
or excentrics ab, the results produced in the positions of the cranks, cams or
excentrics a will be successively those shown in Fig. 6 Fig. 7. Fig. ·. Fig. 8.
Fig. 5. Fig. 6. Fig. 5 Fig. 5 Fig. 7. Fig. 7. Fig. 6. Fig. 6. Fig. 8. Fig. 8. Fig. 7
Fig. 8. and Fig. 6.
The reference letters on the plates or cards of the chain serve to indicate the
different kinds of plates or cards employed and each reference letter serves to
indicate as is obviously the case plates or cards similar to that shown in that one of
the Figs. 1. 2. 3. and 4, which bears the same reference letter. At each time that
either of the needles or darts or other devices aforesaid is acted upon by a plate or
card the end of such needle or dart or other device is moved so that it would not be
acted upon by a plate or card similar to that last presented to the darts or needles.
I have in Fig. 9. indicated by means of the dotted circles', and ', on each plate
or card of the chain the position into which the needle or dart or device or needles
or darts or devices acted upon by such plate or card would be moved after being
acted upon by such plate or card. The dotted circles j', k', on each plate or card
also serve to indicate the position occupied by the darts or needles or devices when
the next plate or card of the chain is presented to them. If Fig. 9. be inspected it
will be found that all plates or cards marked c by acting, or failing to act, as may
be required upon one or other or both of the needies or darts or other devices to
which they are presented cause the cranks, cams or excentrics a, b, to assume or
remain in the position in which they are indicated in Figure 5, that all the plates
or cards marked d, in like manner, cause the cranks cams, or excentrics to assume
or remain in the position in which they are indicated in Figure 6, that all the
plates or cards marked e in like manner cause the cranks, cains or excentrics a, b, to
assume or remain in the position in which they are indicated in Figure 7, and that
all the plates or cards marked, in like manner cause the cranks, cams or
excentrics a, b, to assume or remain in the position in which they are indicated in
Figure 8. It will also be found that plates or cards of one kind always produce
the same result whatever may be the position of the cranks, cams or eccentrics
when such plates or cards are presented to the needles or darts or other devices
controlling the movement of such cranks, cams, or eccentrics a, b.
Although I have in Figs. 1 2 3 4 and 9 indicated that the movement imparted
to each needle or dart or other device after it has been acted upon by a plate or
card is in the direction of the lengths of the plates or cards such movement may
be in any other direction as may be desired if the plates or cards be made of
suitable form.
In the preceding description of the diagrams Figs. 5. 6. 7. and 8. it is assumed
that the raising of the connecting rod or other corresponding part to which
the cranks, cams or excentrics aforesaid impart motion corresponds to the
descent of the shuttle-boxes but if the ascent of such connecting rod or other
corresponding part corresponds to the ascent of the rising and falling shuttle-boxes,
the diagrams Figs. 5, 6, 7, and 8, will also apply if it be remembered that Fig. 5.
in that case indicates the position of the cranks, cams or excentrics when the fourth
box is in position to receive a shuttle and Figs. 6. 7. and 8. respectively indicate
the positions of such cranks, cams or other excentrics when the third, second and
first boxes are in such position.
Although I have above described this part of my invention as applied to a loom
provided with four rising and falling shuttle-boxes this part of my invention may

page_text: also as will be understood without further description be applied to looms provided
with six or eight rising and falling shuttle boxes operated by means of three
cranks, cams or excentrics the movement of each of which is controlled by a
separate needle, dart or other device, provision being made for moving each needle
or dart or other device when it has been acted upon by a plate or card into a
position such that a plate or card similar in so far as regards the portion intended
to act upon such needle or dart or other device would not act upon such needle,
dart or other device.
The adoption of this part of my invention enables pattern-chains to be very
readily arranged as a plate or card of one kind always produces the same effect
upon the position of the shuttle-boxes whatever may be the position of such
shuttle-boxes when such plate or card is presented to the needles or darts or other
devices by means of which the movements of the parts operating or controlling the
movement of the shuttle-boxes is caused or controlled.
A further part of my invention consists in arrangements by means of which I
cause each of the needles or darts or other devices above mentioned to move as above
described when acted upon by a plate or card or other appliance of the pattern
chain. According to this part of my invention I form upon any suitable part
which revolves or moves at the time when a change in the position of the shuttle-
boxes takes place, a suitable cam which I cause to act by suitable means and in any
suitable manner upon the dart or needle or device which has by being acted upon
by the card or plate or appliance of the pattern-chain brought about such change
of position of the shuttle-boxes so that such dart or needle will be moved or turned
vertically or horizontally or in any other suitable direction into a position in which
it would fail to be operated upon by a card or plate or appliance similar in so far
as concerns the part which would operate upon the said needle or dart or device to
that which last operated upon it. A similar arrangement or similar arrangements
is or are employed in conjunction with the other needle or dart or device or the
other needles or darts or devices employed in the loom to which this portions of my
invention is applied.
One method of carrying this part of my invention into effect is illustrated in
Figs. 11 and 12 of the accompanying drawings, Fig. 11 being a plan partly in
section and Fig. 12 an elevation partly in section. The arrangement illustrated
in Figs. 11 and 12 is particularly applicable to looms such as are described in the
Specification of James Cowburn and Christopher Peck above referred to but is
also applicable to other looms in which disc-like parts are employed in conjunction
with the apparatus by means of which the movements of the shuttle-boxes are
caused or controlled. In Figs. 11 and 12 m m are the discs employed in
the arrangement described in the said Specification of James Cowburn and
Christopher Peck and n n are the needles or darts or devices by means of which
the cards or plates of the pattern-chain employed are enabled to press one or other
or both of the reciprocating racks o into gear with the one or other or both of the
wheels m¹ m¹ formed upon the discs m m respectively. Each of the needles or darts
or devices n is near one end mounted so as to be capable of being moved longi-
tudinally in a guide or support p secured to any suitable part of the loom. Near
its other end each of the needles or darts or devices n passes through a guide or
support secured to any suitable part of the loom. The needles or darts or
devices are kept in position in the guides or supports p and q by means of
removable covers p₁₁ secured to the said guides or supports p 7 respectively.
Each of the needles or darts or devices n is mounted upon and guided by a stud q³
formed or secured upon a projecting part q³ secured to the guide or support q which
stud passes through a slot n' formed in the said needle dart or device n. Upon
each of the discs m m is formed a projecting part with an inclined surface r
leading from the face m² of the disc m to the surface of such projecting part r.
In conjunction with each of the needles or darts or devices n n is provided a spring s
which is mounted upon a rod t and at one end abuts against a lug n¹ formed upon
the needle or dart or other device n through which the rod t passes and at the other

page_text: arrow E causing the projection or guide y to be moved either, from the position in
which its point or extremity K is indicated in Fig. 13 into the position in which its
point or extremity K is at L or from the position in which its point or extremity K
is at L into the position in which it is shown in Fig. 13 according as the point or
extremity K of the projection or guide y is in the position in which it is indicated
in Fig. 13 or at L when the needle or dart or other device n commences to move in
the direction opposite to that indicated by the arrow E it follows that each time the
needle or dart or other device n will on completing its movement in the direction
of the arrow E after having been moved by a card or plate of the pattern chain in
the direction opposite to that indicated by the arrow E occupy that one of the two
positions in which it is indicated by full lines and by dotted lines respectively in
Fig. 13 which it did not occupy when the movement which it last performed in the
direction opposite to that indicated by the arrow E was commenced.
The other needle or dart or device or needles, darts or devices employed in the
loom in which the needle or dart or other device illustrated in Figs. 13, 14 and 15
of the accompanying drawings is employed is or are arranged and operated in a
manner similar to that in which the needle or dart or other device n illustrated in
Figs. 13, 14 and 15 is arranged and operated.
The arrangements of apparatus herein before described in reference to and illus.
trated in and by Figs. 11 and 12 and 13, 14 and 15 of the accompanying drawings
ensure that a needle or dart or other device when acted upon by a card or plate of
the pattern-chain employed to cause or control the movement of the rising and
falling shuttle-boxes of a loom in which either of such arrangements is employed
shall move into the position of the two which it may occupy which is different from
that which it occupied when the said card or plate acted upon it and the said
arrangements of apparatus enable the hereinbefore described method of ensuring
that a plate or card of each kind employed shall bring one shuttle-box and one
shuttle-box only into position for delivering or receiving a shuttle to be readily
carried into effect.
In Figs. 11 and 12 of the accompanying drawings the needles or darts or devices n
are shown as being provided with parts n adapted to act when required upon the
detents u employed in conjunction with the discs m of the arrangement of apparatus
described in the above mentioned Specification of James Cowburn and Christopher
Peck but my invention being applicable to other looms in which the shuttle-boxes
are brought into the various necessary positions by changes being made in the
relative positions of cams, cranks or excentrics employed to operate the shuttle-
boxes, the needles or darts or other devices n employed will require to be adapted
to operate the parts requiring to be operated in the looms in which such needles or
darts or other devices are employed.
Although I have above in many cases only referred to the pattern-chain to which
my invention is applied as being formed of plates or cards I would have it under-
stood that my invention is also applicable to pattern-chains consisting of other
equivalent appliances.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. For use in looms of the kind hereinbefore described for the purpose of causing
or controlling the movements of the rising and falling shuttle-boxes employed in
such looms and in combination with each other, needles or darts or other equivalent
devices each of which when or after being acted upon by a card or plate or other
equivalent appliance of the pattern-chain employed is moved into and retained in
that of two positions which is different from that in which it was when the said
card or plate or other equivalent appliance acted upon it and a pattern-chain
formed of cards or plates or equivalent appliances each of which is provided with
two parts for use with each of the needles or darts or other equivalent devices
aforesaid the one of two such parts which is opposite to the needle or dart or other

page_text: equivalent device with which such two parts are used depending upon the position in
which such needle or dart or other equivalent device was placed when or after being
acted upon by the card or plate or other equivalent appliance which last acted upo.1
it and arranged employed and operating for the purposes and substantially in
the manner herein before described.
2. For use in a loom of the kind herein before described in which a pattern-chain
formed of cards or plates or other equivalent appliances each of which has
for use with each needle or dart or equivalent device in conjunction with which it
is employed two parts one or other of which is opposite to the needle or dart or
other equivalent device in conjunction with which it is employed according to the
position occupied by such needle or dart or other equivalent device when the card
or plate or other equivalent appliance of the pattern-chain is presented to the said
needle or dart or other equivalent device the arrangements of apparatus herein-
before described in reference to and indicated in and by Figs. 11 and 12 and
Figs. 13 14, and 15 of the accompanying drawings by means of which each of the
needles or darts or other equivalent devices employed in conjunction with a pattern-
chain to cause or control the movement of the rising and falling shuttle-boxes is
moved after being acted upon by a plate or card or other equivalent appliance of
the pattern-chain into a position in which it would fail to be operated by a plate or
card or other equivalent apparatus similar in so far as concerns the part which
would act upon the said needle or dart or other device to that which last acted
upon it substantially in the manner hereinbefore described.
