Office," No. 8, Southampton Buildings, Chancery Lane, in the County
of Middlesex, Civil Engineer, for the Invention of "IMPROVEMENTS IN
LOOMS AND SHUTTLES FOR WEAVING."-A communication from abroad by
Benjamin Oldfield and Edward Oldfield, both of Newark, New Jersey,
United States of America.
Sealed the 7th May 1867, and dated the 6th December 1866.
PROVISIONAL SPECIFICATION left by the said George Haseltine at
the Office of the Commissioners of Patents, with his Petition, on the
6th December 1866.
I, GEORGE HASELTINE, of the "International Patent Office," No. 8, South-
ampton Buildings, Chancery Lane, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN LOOMS AND SHUTTLES FOR WEAVING," & communication, to be as
follows:-
The said improvements are applicable to looms of every description, but
are more especially adapted to looms for weaving a number of pieces simul-
taneously.
The shuttle is provided with pins or studs projecting from its ends, and is
supported thereby, the ordinary grooves and tongues being dispensed with. A.

page_text: loose tension spring is inserted in one end of the said shuttle, which can
thereby be readily taken out and replaced. The said shuttle is furnished with
bearings in its cheek pieces to receive the centres of the bobbin or reel which
carries the weft; the said bobbin or reel is employed instead of the long quill
commonly used, and a much larger quantity of weft can be thereby carried in
the shuttle, while the danger of an entanglement is materially reduced; the
said reel is retained in its place by a spring catch which allows it to be readily
removed and reinserted; the insertion and removal of the said reel is also
greatly facilitated by making the shuttle taper from the rear end to the eye.
The shuttle may be constructed of metal plates united by solder or other
suitable means, and when so produced will be found much lighter than an
ordinary wood shuttle, while the cost of manufacture is materially lessened.
The shuttle carriers are provided with rising and falling pegs or other
suitable catches which are arranged to act in combination with the pins or
studs on the ends of the shuttle to receive and retain the latter, and to carry
it through the shed; the said pegs or catches are operated by cam guides
which are arranged to act in combination with the shuttle carriers. The
required movement of the said shuttle carriers in either direction and at the
proper intervals is effected mainly by means of two slide bars or equivalent
devices; these slide bars move in a straight line without rising and falling,
and are provided with uprights with holes formed in them to receive a stud
or peg for carrying a shuttle, motion being communicated to each of the said
studs or pegs by a cäm or equivalent device; by this means a simple and
effective shuttle motion is obtained which can be employed in looms of any
description. Cross-shaped pegs are arranged in combination with the shuttle
carriers to prevent the tipping down of the shuttle; two or more slide bars
are situated in the same horizontal line, and are operated by racks and toothed
wheels instead of the cords and pulleys ordinarily employed for this purpose;
one or more peg slide bars are combined with the said racks and toothed
wheels whereby a sure and safe shuttle motion is obtained which is not liable
to derangement. Cams are fixed or formed upon the said toothed wheels.to
impart the required motion to the slide bars, whereby the latter are locked and
prevented moving except at the proper moment. A speed pulley is arranged
iu combination with the pegs or catches and with the treadle or equivalent
device, whereby the speed of the shuttle can be reduced to the lowest possible
rate which enables it to clear the work while the speed of the loom is increased
in proportion.
A parallel motion is combined with the batten, by means of which the
latter is moved in a straight line, or nearly so, the friction on the threads
warp

page_text: being thereby prevented, and the opening of the shed reduced. The harness
motion is composed of arms which are attached at one end to a long lever,
and are operated by a circular or segmental chain wheel or equivalent device,
so that each harness frame as it is indicated by the pattern device will bo
readily lifted. The harness or heddles are locked and held up or down for
any number of picks indicated by the said pattern device; the said harness is
operated by cranks which are arranged to turn independently of each other
when carried either partially or wholly to the end of their throw, as indicated
by the pattern chain or equivalent device. The wheels which carry the loose
arms are operated either by chains and hooks or by racks and pinions. Studs
or projections provided with elastic cushions or springs are arranged in com-
bination with either ridges or cavities on the inner surface of the leaves of the
pattern chain, which pins or studs can be readily inserted and removed by
pressure.
A stop motion is attached to and operated by the shuttle motion which
prevents the shuttle's coming in contact with the work if at any time it fails
to reach its proper position; the said stop motion is provided with a brake
whereby the loom is stopped almost instantaneously, and all danger to the
work is avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Haseltine in the Great Seal Patent Office on
the 5th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 8, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Civil Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of December, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said George Haseltine, Her special licence that I, the
said George Haseltine, my executors, administrators, and assigns, or such
others as I, the George Haseltine, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom

page_text: of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN LOOMS AND SHUTTLES FOR WEAVING," upon the
condition (amongst others) that I, the said George Haseltine, my executors or
adminstrators, by an instrument in writing under my, or their, or one of their
lands and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying Drawings forming a part
of this Specification:-
These improvements relate chiefly to the shuttle, the shuttle motion, the
batten, and the harness motion, and are applicable to looms of any description,
but are more especially adapted for those on which a number of pieces are
woven simultaneously.
The shuttle, unlike the ordinary wooden shuttle, is made of thin metal
plates, which are united by solder or other suitable means, and is much
cheaper, more durable, and lighter than an ordinary shuttle made of wood;
the said shuttle is provided with cheek pieces or other suitable means for
receiving the centres on which the reel turns; this reel is used in place of the
ordinary long quill in any shuttle of suitable construction, and it serves to pass
the weft through the warp, the weft thread being made to unwind from the
said reel, while the batten is in motion in such a manner that a larger quantity
of thread can be put in the shuttle than in ordinary shuttles with a long quill,
consequently the number of stoppages of the loom are reduced, and through
the increased diameter of the reel, and its position in the shuttle in relation to
the shuttle eye, the drag on the said eye is prevented, and the thread is less
liable to get entangled or broken, thus producing a superior fabric both in
quality and in quantity. The tension of the weft thread is regulated by a
spring, which is inserted loosely in one of the pins or ends of the shuttle, so
that it can be easily removed and replaced by another of different strength
according to the nature of the work to be produced. A tension spring of the
ordinary construction may be applied, and a check spring is combined with
the said tension spring to prevent the reel from giving off more weft than
required. The operation of introducing and removing the reel is facilitated
by giving to the shuttle a tapering shape from its eye towards its rear edge,
and by providing the same with a spring catch or moveable bridge piece,

page_text: which can be sprung back or removed so as to release or admit the reel. The
shuttle is carried through the shed of the warp by shuttle carriers, which
move back and forth on guide bars secured to the batten; these guide bars
form cams which act on loose pegs in the said shuttle carriers, and cause then
to rise or fall at the proper intervals, and to catch in or release the ends of
the shuttle. For shuttles of the ordinary construction the upper ends of the
loose pegs are provided with a shoulder to prevent the shuttle from tipping
down in front. The shuttle carriers are attached to slide bars, which move on
top of the batten in a straight line without rise and fall, and the ends of which
form toothed racks, which gear into toothed wheels in such a manner that by
the action of the said toothed wheels the required reciprocating motion is
imparted to the slide bars, shuttle carriers, and to the shuttle. The teeth of
the racks instead of being of solid metal are produced by corrugating a strip
of sheet metal. Suitable cams attached to or formed by the toothed wheels
act upon stops on the slide bars, and prevent the same from moving or being
moved prematurely.
The motion from the driving shaft to the shuttles is transmitted by an
ordinary "marionette motion" or any equivalent device, and a pulley inter-
posed between this "marionette motion" or equivalent device, and the shuttle
motion allows of regulating the speed of the shuttles and of reducing this
speed to the smallest possible point, enabling them to clear the work, and the
speed of the loom may be increased in proportion. The motion of the main
shaft is regulated by eccentric wheels, cams, or other equivalent means in such
a manner that the speed of the batten can be reduced as it is coming to, and
the weft thread is prevented being drawn off too fast, and in consequence
thereof the speed of the loom can be increased.
A parallel motion of any suitable construction is combined with the batten,
so that the latter is carried in a straight line, or nearly so, and thereby friction
on the warp threads is prevented, and the opening of the shed can be
reduced.
A cam or eccentric attached to or operated by the shuttle motion acts on a
spring stop and depresses the same, so that when the shuttle motion is out of
order the said spring stop through suitable connections acts on the belt shipper,
and the driving belt is shifted from the fast to the loose pulley, causing the
loom to stop before any damage is done. A suitable brake is combined with
this stop motion to render the latter still more effective. The harness motion
is composed of arms which are attached at one end to a lever and operated by
a circular or segmental chain wheel or crank in such a manner that each
harness frame can be readily raised or depressed as the pattern chain may

page_text: indicate. The harness or heddles are operated by cranks capable of being
turned independently of each other when carried either partially or entirely to
the end of their throw, the same being operated by the pattern chain. The
said harness or heddles can be easily locked for any number of picks, as
indicated by the pattern chain. The wheels which carry the arms of the
harness motion are operated either by chains and hooks or by racks and
pinions, and the motion of the harness is rendered irregular by eliptical or
cccentric wheels or any equivalent means which will produce the same effect,
so that the strain on the warp thread is reduced, and the speed of the loom
can be increased in proportion. The pins or studs of the pattern chain are
supported by elastic cushions or springs, and they are provided with T-headed
shanks, which pass through oblong slots in the leaves of the pattern chain.
These leaves are provided on their inner surfaces with ridges or cavities
extending at right angles to the oblong slots, so that by depressing the pins
or studs and turning them one quarter round their T-headed shanks are
caused to catch between the ridges or in the cavities, and the said pins or
studs can be readily inserted or removed by pressure.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan of the top of my improved loom; Figure 2 is a sectional
front elevation of the same on the line X, X, Figure 1; Figure 3 is a.
sectional side elevation of the harness motion; Figure 4 is an end view,
showing the harness motion; Figure 5 is a similar view, showing the shuttle
motion and stop motion. The remaining Figures represent details and
modifications of my improvements which will be referred to more particularly
in the following description. Like letters indicate the same parts in each of
the Figures.
The shuttle S is constructed by preference of metal plates a, which are
united by solder or other suitable means. If desired, however, the shuttle
may be made of wood or any other suitable material. The cheek pieces a
are provided with bearings to receive the centres on which the reel R turns in
contradistinction to shuttles of the ordinary construction in which a long quill
is used, which is secured in the end of the shuttle (Figures 6, 7, and 8).
From the ends of the shuttle S project pins b, which may be square or
round, and which serve to support the shuttle either in a horizontal or in an
upright position. By using these pins the grooves and tongues generally used
may be dispensed with in shuttles of looms on which a number of pieces are
woven simultaneously, and the construction of the shuttle and that of the batten
is materially cheapened and simplified. The pins 6 are made hollow to

page_text: receive the tension spring c, which bears on the surface of the thread wound
on the reel. By these means the said tension spring is readily applied, it can
be easily changed to suit the nature of the work to be produced, and its action
regulates itself automatically according to the varying diameter of the roll of
thread on the reel. The reel R is inserted between or placed on one of the
cheek pieces of the shuttle, one of which is provided with a moveable or elastic
bridge piece or spring catch d, whereby the operation of inserting and removing
the said reel is materially facilitated. The shuttle is made taper from the eye
towards its back, so that the reel can be readily put in or taken out from the
back of the shuttle, the cheek pieces preventing the reel from being lifted out
of place and coming in contact with the warp (Figure 8) and the tension
spring c instead of being secured in the hollow pin as shown in Figure 6
may also be fixed to the shuttle and made to operate on the edge of the reel,
or the tension spring can be put in loosely and much time and labor in the
construction of the shuttle saved.
Instead of constructing the shuttle as shown in Figures 6, 7, and 8 it may
be constructed as shown in Figures 14, 15, and 16, or in the manner shown
in Figures 17 and 18. Figure 14 represents a plan, Figure 15 a front
elevation, and Figure 16 a transverse section of the shuttle S*, the cheek
piece of which forms a base plate a*, the edges of which fit into the shuttle
race and from which rise the standards supporting the cylindrical body of the
shuttle, and also the vertical pin c*. The shuttle race is formed by metal
pieces g*, as shown in Figure 16, which extend all the way across the bottom
of the base plate and support and guide the same. On this pin is placed
the reel, and to the inner surface of the shuttle are secured the tension
spring d* and the check spring e*. The tension spring bears on the surface
of the thread or yarn, and the check spring on the circumference of the reel.
The object of the said check spring is to prevent the weft being drawn off too
fast. From the bottom edge of the cylindrical body of the shuttle project
two flanges f* with holes to receive the driving pegs or if desired the
shuttles may be driven by racks and pinions.
Figure 17 is a plan, and Figure 18 a transverse section of another modi-
fication of the shuttle, which is provided with a back plate a**, from the rear
side of which extend the tongues and grooves for supporting the shuttles in
the races, while from its front side extends the body S** of the shuttle, which
is provided with a cheek piece b** for supporting the pin c** which receives
the reel; this cheek piece may be made to project past the outside of the
body of the shuttle to make room for holes to receive the driving pegs, or the
shuttle may be driven by racks and pinions. The shuttles are provided with

page_text: two or more eyes, as shown in Figure 15, so that the position of the weft can
be regulated to suit the different natures of the work. The reel R takes the
place of the long quill generally used in 'shuttles for looms, and on it is wound
the weft thread which is carried by the shuttle through the warp. By
using the reel in place of the quill a large quantity of thread can be put in
the shuttle, and consequently the number of stoppages on the loom are
decreased, and though the increased diameter of the reel and its position in
the shuttle in relation to the shuttle eye the drag on the eye is prevented,
and the thread is less liable to get broken. As the shuttle passes through the
shed of the warps, or during the time the batten is in motion, the weft thread
is drawn off from the reel precisely in the same manner as it is drawn off from
the long quill in ordinary shuttles.
It will be readily understood that a shuttle constructed as above described
may be worked either horizontally or in an upright position, and two or more
shuttles can be placed one above or behind the other. The tension of the weft
thread is regulated by the spring c on the springs d, e, as previously
described. The pins b, which extend from the ends of the shuttle, fit into
shuttle carriers C, which are provided with suitable sockets e to receive the
same, and these shuttle carriers are provided with loose pegs f, which rise
and fall by the action of cams g at the proper intervals, and which as they
rise catch in suitable. sockets or cavities in the pins 6 (shown in Figure 12).
Instead of making the shuttle carriers with sockets to receive the pins 6 they
may be made as shown in Figures 13, 14, and 17, and in this case they are
adapted for shuttles of the ordinary construction, and the pegs f* may be
provided with shoulders to prevent the shuttle from tipping down. The
shuttle carriers move back and forth on guide bars h, which are secured in the
top of the batten, as shown in Figures 1, 2, and motion is imparted to the
said shuttle carriers by slide bars D, to which they are rigidly attached. The
slide bars are situated on the same or opposite sides of the guide bars or cams,
and they move back and forth without rise and fall; their motion is pro-
duced by toothed wheels E, which gear in teeth i cut in the edges of the
slide bars, and which are mounted on a shaft j, to which an oscillating or
rocking motion is imparted by suitable mechanism herein-after more fully
described. The rack teeth and toothed wheels E take the place of the cords
and pullies generally used for the purpose of imparting motion to the shuttles
in looms on which a number of pieces are woven simultaneously. The rack
teeth i may be made to extend the whole length of the batten, and they may
be produced of corrugated sheet metal, as shown in Figure 19. On the side
of each of the toothed wheels E, and firmly attached thereto or mounted on

page_text: the shaft j. are cams F, F; these cams act against stops k, secured to the
'outer surfaces of the slide bars D. The said cams are so shaped that by their
action on the stops each slide bar is locked until the proper time arrives for
it to move. By this arrangement the pins. 6 of the shuttles are enabled to
enter the sockets of the shuttle carriers without fail, and the said shuttle
carriers are firmly retained in position until the pins of the shuttles have
passed into them to the required distance. One of the slide bars is provided
with a lip or change d', which occupies such a position that the other slide
bar on moving in the proper direction strikes the said lip, and both slide bars
are thereby caused to move a short distance simultaneously. By this arrange-
ment the pegs used to drive one and the same shuttle are kept both in the
sockets of the shuttle for a short time, and the motion is rendered safe and
reliable. The lip or change d³ is made detachable, and by removing it the
slide bars can be brought in such a position that all the pegs are dropped
simultaneously, leaving the shuttles free, so that the same can be removed
without difficulty or loss of time. By combining two slide bars with one set of
cams in the manner shown the pegs can be dropped at the ends of the shuttle
races without causing the slide bars to rise. and full, and the shuttle motion
is simplified in its construction and rendered. sure in its operation. If the
shuttles are driven by racks and pinions the cams and guide bars may be
dispensed with. The motion of the shaft j is produced by a chain l, which
extends over a chain wheel m mounted on the said shaft and made to pass
under a pulley or drum n; this pulley or drum is mounted on a shaft o, to
which a rocking motion is imparted by what is technically known as a
"marionette motion," or by any other equivalent mechanism. In looms of
the ordinary construction the "marionette motion" connects directly with the
shuttle motion, and the speed of the shuttle cannot be regulated. By inter-
posing the speed pulley n between the "marionette motion" and the shuttle
motion I am enabled to regulate the speed of the shuttles simply by increasing
or decreasing the diameter of the said pulley, so that the speed of the shuttles
'can be reduced to the smallest possible point, enabling them to clear the work,
and the speed of the loom may be increased in proportion.
Instead of transmitting the motion from the "marionette motion" to the
shuttle motion by chains and pullies, the "marionette motion" may bo
arranged as shown in Figures 20 and 21. .In this case the shaft is extended,
and on its end is mounted a toothed wheel *, which is so arranged by means
of a feather key and groove that the shaft is compelled to revolve with the
said wheel, but it is free to slide therein back and forth in accordance with the
motion of the batten. The rising and falling bars of the "marionette motion"

page_text: are provided with rack teeth which gear in the toothed. wheel h*, and as the
said bars are raised or depressed by the action of the treadle or rod the
shaft j is revolved and the shuttle motion is produced. The irregular motion
of the shuttles in this case may be produced by the arrangement of an
eccentric gear i*, Figure, 1 on the main shaft K, the said gear being employed
to transmit the motion from the driving shaft K* to the main shaft, or instead
of the eccentric gear a cam groove might be applied to impart an irregular
motion to the rod. With the shuttle motion of the loom berein described a stop
motion is combined whose action is based on a rising and falling spring stop s,
which is depressed by a cam or excentric t mounted on the shaft j. If the
shuttle motion works correctly, the spring stop is depressed at such intervals
that the same will clear the shoulder or offset u in the bar E'; this bar is
supported by slotted brackets F¹ in which it is permitted to slide back and
forth, and it is provided with a hook v which catches in a hole in the spring
lever w. If the hook is made to release this spring lever it follows the
action of its spring, and causes the belt shipper H to move in the direction of
the arrow Figure 1, and by this movement of the belt shipper the driving
belt is thrown from the fast pulley I to the loose pulley I', and the loom stops.
If the shuttle motion from any reason becomes deranged, or if it does not
work correctly, the spring stop s is depressed at such a time that it comes in
contact with the shoulder u, and the hook v is immediately made to release
the spring lever w, causing the loom to stop before the shuttle comes in contact
with the fabric. The stop motion is rendered still more effective by the brake G
formed by an arched strap a¹ which extends over the fast pulley, and which
is made to bear on the surface thereof whenever the spring stop strikes the
shoulder u. The batten B instead of being secured directly to the ends of
the swords as usual is combined with a parallel motion P which may be com-
posed of four hinged levers p, four links q, and two connecting rods v, or
which may be constructed in any other suitable manner. By the action of
this parallel motion the batten is made to move in a horizontal plane or
nearly so; the friction on the warp threads is thereby prevented, and the
opening of the shed reduced. If it is desired to give an irregular motion to
the batten, this motion may either be produced by the eccentric gear i* on
the main shaft Figure 2, or by cams taking the place of the eccentrics shown
in Figures 1, 2, and 5. The pulleys I, I', are either mounted on the main
shaft K, which has its bearings in suitablo boxes in the main frame of the
loom, or on a driving shaft K*, which is connected with the main shaft by
the eccentric gear i*, as shown in Figure 2. On the end of the said main shaft
opposite to the pullies is secured the bevel wheel b, which gears into a similar

page_text: bevel wheel c' on the end of a shaft d, whose bearings are formed in suitable
arms or brackets secured to the main frame of the loom. If the eccentric
gears are used an irregular motion is given to the main shaft and all parts
driven by the same, and the motion of the batten and of the other parts of
the loom can be so regulated that the speed of the loom can be increased.
If the motion of the main shaft is uniform an oval wheel e is mounted on
the shaft d', and this wheel has its bearings in suitable arms or brackets or
in the side pieces of a frame J which supports the principal mechanism of
the harness motion; this harness motion is composed of arms L, cach of
which is attached at one end either to a long lever M or to a bell-crank lever q',
and at the opposite end to a circular or segmental crank wheel N or any
equivalent device.
In Figures 1, 2, 3, and 4 crank wheels are shown to which an oscillating
motion is imparted by means of chains h¹ passing over the said crank wheels,
and from whose ends rods are suspended; these rods pass through slots
in the arms which project from a rocking shaft k' and bear against the pattern
chain. The said rods are provided with hooks which are hinged and so
arranged that they can swing back, but not inwardly or towards each other
beyond a certain point, as shown particularly in Figures 3. Between the
rods and hooks extends the knife O which moves up and down on
vertical guide bars m³, and to which motion is imparted by means of rods n¹
which extend from its ends to the eccentric wrist pins o¹ secured in discs p¹;
these discs are mounted on the shaft g which receives an irregular revolving
motion by the oval wheels e¹, f¹, or by the irregular motion of the main shaft,
and by this irregular motion the harness motion is so timed that the warp
threads are exposed to the least possible strain, and consequently the speed of
the loom can be increased. As the knife O passes up the hooks are pressed
back, but when the said knife descends it catches into such of the hooks as
are brought in the proper position by the pattern chain, and the corresponding
heddles are raised or depressed. This motion is effected as follows:-Each
heddle frame is suspended by cords or wires from elbow levers q¹ which have
their fulera on suitable cross bars or pins in the top rail of the loom, and
which are also connected by suitable cords or wires with the top ends of the
long levers M, as clearly shown in Figure 2, or directly with the arms L, as
shown in Figure 22. From the under edges of the heddle frames extend
cords or wires round pulleys in the bottom part of the loom, and these
cords or wires are attached to the lower ends of the long levers M; or if the
motion is arranged as shown in Figure 22 the pulleys are replaced by

page_text: elbow levers which connect by arms with crank wheels similar to those
shown on top of the loom. By providing the crank wheels with two or
more holes, and by changing the pins which form the connection between
the crank wheels and arms L from one hole to the other, the size of the
shed can be regulated to suit the shuttle. Each of these long levers is
connected with one of the crank wheels N, and from each crank wheel
are suspended two rods i, one on either side of the knife O, as shown in
Figure 3. These rods pass through their slotted arm j, and if this arm is
pressed back by the action of the pattern chain, as shown in the same
Figure, the knife O in descending catches in the hook of the outer rod i¹,
and the crank wheel N is turned in the direction of the arrow (Figure 3).
By this motion of the crank wheel the arm L attached thereto is caused to
'move in the direction of the arrow, and the heddle frame attached to its long
lever is raised. If the pattern chain revolves and the slotted arm j¹ is per-
mitted to move out in the direction of the arrow, the hook attached to the
inner rod is brought in such a position that the knife on its subsequent
descent will catch in the same, and the said inner rod will be thereby carried
down, and the heddle frame attached to the long lever M is depressed. It
is obvious that by these means each heddle frame can remain in an elevated
or depressed position for any number of picks, as indicated by the pattern
chain, and the said heddle frames are not permitted to descend or rise until
the corresponding slotted arms or vibrators j₁ are permitted to drop. If
desired a suitable locking device, such as a weak spring or brake, may be
applied to the long levers to counterbalance the weight of the heddle frames,
and to keep the same up or down as long as may be required by the pattern
chain. The long levers M can also be operated by cams, as shown in
Figure 24, but in this case the pattern chain is dispensed with. If desired
the crank wheels N might be replaced by toothed wheels or toothed segments,
and in this case the upper ends of the rods ¹ would be formed into toothed
racks, or the said rods would be connected to toothed racks. The arms I
instead of being pivoted to the crank wheels might be provided with teeth on
either edge, which could be made to gear into toothed wheels or pinions
attached to the sides of the crauk wheels, or mounted on the same shaft with
the said crank wheels and close to the same. All such changes I would con-
sider equivalents to the devices previously described and represented in the
Drawings. If the harness motion is constructed as shown in Figures 22 and
23 the position of the rods i¹ cannot be changed by the pattern chain, and in
this case the pattern chain acts in the scolloped vibrators j*, which serve to

page_text: change the position of the hooks or catches
by its action on the dogs 12*,
are held in gear with the,
as shown in Figure 23; in this case the rods
crank wheels by cross rails 2, which also serve to prevent the arms L from
dropping down below the desired position, and which in this respect take the
place of the rods i, shown in Figures 1, 2, and 3. The pattern chain Q is.
constructed in the ordinary manner, with the exception that the pins or
studs are secured in the same in such a manner that they can be readily,
put in or removed by pressure; this object is effected by placing under the.
said pins or studs elastic cushions S', so that after the T-shaped shanks of
the same have been introduced through the slots t¹ in the leaves of the pattern.
chain (Figure 11) and turned so as to bring the heads of the shanks at.
right angles to the slots the elastic cushions will force the said heads into
recesses u on the inner surfaces of the leaves, and the studs or pins are firmly.
held in position. By depressing one of the studs against its elastic cushion.
until the head of its shank clears the recess at the inner surface of the leaf
said stud or pin can be turned and removed. By these means the operation of
inserting and removing the studs is rendered easy, and the pattern chain can,
be changed with little trouble or loss of time.
