Improvements in Certain Machinery or Apparatus for Chaining or
Linking Warps and for Forming Warps from Yarns or Threads,
and for Chaining or Linking the same.
I RICHARD HURST of Spring Hill, Rochdale in the County of Lancaster, the
Administrator of the estate of William Hurst, deceased, late of Hamer Hall,
Rochdale in the County of Lancaster, Machinist, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the machinery or apparatus for chaining or linking
warps and for forming warps from yarns or threads and for chaining or linking the
same, which is described in the Specification of Letters Patent, dated October 24th,
1883, and numbered 5059, granted to William Hurst, and also to the improved
form of such machinery or apparatus in which the lever or arm carrying the trumpet
or eye through which the yarns or threads forming the warp being chained pass in
order that they may be laid around the hooks with which the machine is provided
while being oscillated or vibrated, bears upon a cam by which its movement is so
varied that the said yarns or threads may be laid around the hooks aforesaid in the
manner requisite.
In machines of the kind above mentioned as hitherto constructed it has only been
possible to form one chain or series of links at once and in consequence of warps
formed of a comparatively small number of yarns or threads being unable to sustain
the strain to which they would be necessarily subjected in being drawn off from a
creel or from a.beam if chained or linked by means of a machine of such kind it has
hitherto been very difficult to employ machines of the kind above mentioned in the
chaining or linking of warps containing only a small number of yarns or threads.
The machines above mentioned as hitherto constructed also require as much
attention on the part of the attendants in charge thereof when forming into a chain
or chained warp less than the maximum number of yarns or threads as when
operating upon the maximum number of yarns or threads, and as the formation of
warps containing only a small number of yarns or threads into chains is very
frequently requisite it has hitherto been necessary for such warps to be formed
into chains by manual labour which is necessarily costly and involves much loss
of time.
This invention consists in improvements by which the chaining or linking of very
small numbers of yarns or threads, or warps formed of only a very small number of
yarns or threads is very greatly facilitated and by which economy in the employ-
ment of machinery or apparatus of the kind above mentioned in connection with
less than the maximum number of yarns or threads upon which it is capable of
operating is made possible.
According to this invention there are provided in combination with one set of
rollers for drawing off the yarns or threads from the bobbins or beam on which
they may be wound in readiness for being formed into a warp or chained or
linked two or three or more sets of parts for forming warps or yarns or threads
into linked or chained warps and one portion of the yarns or threads which have
passed the said rollers is caused to be passed to and operated on by one of the
sets of chaining or linking mechanism and another portion or other portions of
such yarns or threads is or are caused to be passed to the other or another or
others of the said sets of chaining or linking mechanism and operated on thereby.
After being chained or linked the several sets of yarns or threads may be passed
together and delivered to any suitable place or into any suitable receptacle in any

page_text: suitable manner or they may be delivered separately into different places or
receptacles in any manner which may be suitable. In one arrangement of this
invention the sets of chaining or linking mechanism which are employed are so
arranged that two shafts, either or both of which may, if it be preferred, be
formed in sections capable of being connected together or disconnected as may
be desirable from time to time, may suffice to communicate motion from one set of
chaining or linking mechanism to the other or others. One of the said shafts is
caused to impart motion to the sbafts by which motion is communicated to the
'several moving hooks in each set of chaining or linking mechanism and by which
part of the required motion is given to the trumpet or eye through which pass the
yarns or threads to be chained or linked by such set of chaining or linking
mechanism. The other of the said two shafts is caused to impart the remainder of
the required motion to the said trumpet or eye. The clutches or other devices by
which, when the said shafts are formed into sections, the sections of such shafts
are connected together, are so arranged that when the said sections are connected'
together they shall be in proper relative position so that the various parts of the
various sets of chaining or linking mechanism shall perform their respective
movements in the order and at the times requisite and for this purpose flanges
formed upon adjacent sections of the shafts and bolts or other like devices by
which they may be connected may be employed. The sets of chaining or linking
mechanism may be placed in other positions in cases in which it may be desirable
and in such cases the motion may be imparted thereto in any manner which may
be suitable. Suitable guides are provided in order that the chain produced by
the operation of each set of chaining or linking mechanism may be prevented from
becoming entangled with or soiled by contact with any of the mechanism over or
past which it is required to pass.
A machine constructed according to this invention may either be employed to
chain or link warps already wound upon a beam or into any other form or to form
chained or linked warps from yarns or threads wound upon bobbins.

Improvements in Certain Machinery or Apparatus for Chaining or
Linking Warps and for Forming Warps from Yarns or Threads,
and for Chaining or Linking the same.
I RICHARD HURST, of Spring Hill, Rochdale in the County of Lancaster, the
Administrator of the estate of William Hurst, deceased, late of Hamer Hall,
Rochdale, in the County of Lancaster, Machinist, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to the machinery or apparatus for chaining or linking
warps and for forming warps from yarns or threads and for chaining or linking the
same, which is described in the Specification of Letters Patent, dated October 24th,
1883, and numbered 5059, granted to William Hurst, and also to the improved
form of such machinery or apparatus in which the lever or arm carrying the
trumpet or eye through which the yarns or threads forming the warp being chained
pass in order that they may be laid around the hooks with which the machine is
provided while being oscillated or vibrated, bears upon a cam by which its
movement is so varied that the said yarns or threads may be laid around the hooks
aforesaid in the manner requisite.
In machines of the kind above mentioned as hitherto constructed it has only
been possible to form one chain or series of links at once and in consequence of

page_text: warps formed of a comparatively small number of yarns or threads being unable
to sustain the strain to which they would be necessarily subjected in being drawn
off from a creel or from a beam if chained or linked by means of a machine of such
kind it has hitherto been very difficult to employ machines of the kind above
mentioned in the chaining or linking of warps containing only a small number of
yarns or threads. The machines above mentioned as hitherto constructed also
require as much attention on the part of the attendants in charge thereof when
forming into a chain or chained warp less than the maximum number of yarns or
threads as when operating upon the maximum number of yarns or threads, and as
the formation of warps containing only a small number of yarns or threads into
chains is very frequently requisite it has hitherto been customary for such warps to
be formed into chains by manual labour which is necessarily costly and involves
much loss of time.
This invention consists in improvements by which the chaining or linking of very
small numbers of yarns or threads or warps formed of only a very small number of
yarns or threads is very greatly facilitated and by which economy in the
employment of machinery or apparatus of the kind above mentioned in connection
with less than the maximum number of yarns or threads upon which it is capable of
operating is made possible.
According to this invention there are provided in combination with one set of
rollers for drawing off the yarns or threads from the bobbins or beam on which
they may be wound in readiness for being formed into a warp or chained or linked,
two or three or more sets of parts for forming warps or yarns or threads into
linked or chained warps and one portion of the yarns or threads which have passed
the said rollers is caused to be passed to and operated on by one of the sets of
chaining or linking mechanism and another portion or other portions of such yarns
or threads is or are caused to be passed to the other or another or others of the
said sets of chaining or linking mechanism and operated ou thereby. After being
chained or linked the several sets of yarns or threads may be passed together and
delivered to any suitable place or into any suitable receptacle in any suitable
manner or they may be delivered separately into different places or receptacles in
any manner which may be suitable. In one arrangement of this invention the sets
of chaining or linking mechanism which are employed are so arranged that two
shafts which may if it be preferred be formed in sections capable of being connected
together or disconnected as may be desirable from time to time may suffice to
communicate motion from one set of chaining or linking mechanism to the other or
others. One of the said shafts is caused to impart motion to that shaft of the set
or each set of chaining or linking mechanism receiving motion thereby which
communicates motion to the several moving hooks in such set of chaining or linking
mechanism and gives part of the required motion to the trumpet or eye through
which pass the yarns or threads to be chained or linked by such set of chaining or
linking mechanism. The other of the said two shafts is caused to impart the
remainder of the required motion to the said trumpet or eye. The clutches or
other devices by which when the said shafts are formed into sections, the sections
of such shafts are connected together are so arranged that when the said sections
are connected together they shall be in proper relative position so that the various
parts of the various sets of chaining or linking mechanism shall perform their
respective movements in the order and at the times requisite and for this
purpose flanges formed upon adjacent sections of the shafts and bolts or other like
devices by which they may be connected may be employed. The sets of chaining
or linking mechanism may be placed in other positions in cases in which it may be
desirable and in such cases the motion may be imparted thereto in any manner
which may be suitable. Suitable guides are provided in order that the chain
produced by the operation of each set of chaining or linking mechanism may be
prevented from becoming entangled with or soiled by contact with any of the
mechanism over or past which it is required to pass.
A machine constructed according to this invention may either he employed to

page_text: chain or link warps already wound upon a beam or into any other form or to form
chained or linked warps from yarns or threads wound upon bobbins.
In the accompanying drawing is illustrated a machine for linking warps or
forming warps from yarns or threads and chaining or linking the same constructed
according to this invention; Fig. 1 being a side elevation and Fig. 2 a rear
elevation of so much only of such machine as is necessary to illustrate this invention
and the manner of carrying it into effect. In the case of some of the parts shown
only in Fig. I which necessarily shows only one side of the machine it will be
obvious that corresponding parts are employed at the other side of the machine.
In the machine illustrated in the accompanying drawing, there are provided in
combination with one set of rollers for drawing off the yarns or threads from the
bobbins or beam on which they may be wound in readiness for being formed into
a warp or chained or linked; two sets of parts for forming warps or yarns or
threads into linked or chained warps. Each of the said sets of parts for forming
warps or yarns or threads into linked or chained warps is of that improved form of
the machinery or apparatus described in the Specification of Letters Patent, dated
October 24th, 1883, and numbered 5059, granted to William Hurst in which the
lever or arm carrying the trumpet or eye through which the yarns or threads
forming the warp being chained pass in order that they may be laid around the
hooks with which the machine is provided bears, while being oscillated, upon a
cam by which its movement is so varied that the said yarns or threads are laid
around the hooks aforesaid in the manner requisite. As it would be impossible to
show all the constituent parts of each set of parts for forming warps or yarns or
threads into chained or linked warps in the accompanying drawing without
rendering such drawing confused and more or less unintelligible and such parts in
themselves form no part of the present invention some of such parts have been
omitted from the accompanying drawing, but the construction and mode of
operation of the parts which are omitted from the accompanying drawing will be
made obvious by reference being had to the Specification filed in pursuance of the
.conditions of the Letters Patent above referred to. As except for the lever or arm
carrying the trumpet or eye through which the yarns or threads forming the warp
being chained or linked by such set of parts for forming warps or yarns or
threads into chained or linked warps pass being caused to bear upon a cam each
set of parts for forming warps or yarns or threads into chained or linked warps
is similar to the arrangement of apparatus employed for like purposes in the
machine illustrated in the drawings filed with the Specification filed in pursuance
of the conditions of the Letters Patent above mentioned the accompanying drawing
is only made to show such parts of the machine illustrated thereby, as are necessary
to enable the present invention and the manner in which it may be carried into
effect to be fully understood. There are applied to some of the parts shown in the
accompanying drawing the same letters of reference as are applied to the corre-
sponding parts shown in the drawings accompanying the Complete Specification
filed in pursuance of the conditions of the Letters Patent above referred to, and
the construction and operation of such parts will not be further described except in
so far as may be necessary for the description of other parts. To the parts forming
or provided to support the upper set of parts for forming warps or yarns or threads
into chained or linked warps are applied the same letters of reference as are applied
to corresponding parts forming or provided to support the lower set of parts for
forming warps or yarns or threads into chained or linked warps but in the case of
the upper set of such parts the letter (*) is added in order that whenever it may be
necessary a distinction may be made between a part in the upper set of parts and
a part in the lower set. In order to facilitate distinction between such of the
letters of reference in this description which are adopted from the drawings
accompanying the Complete Specification filed in pursuance of the conditions of the.
Letters Patent aforesaid and such of the letters of reference herein as are
employed solely for the purposes of the present description the letters of reference
employed solely for the purposes of the present description are enclosed within
brackets () both in this description and in the accompanying drawing.

page_text: (1) (12) are the cams upon which bear the arms 16, 163, carrying the eyes or
trumpets 18, 18*, by means of which the yarns or threads forming the warps to be
chained or linked are laid around the fixed hooks of which those 40, and 40*
situate at one side of the machine only are shown. The cams (1) (1³) are
respectively mounted upon shafts e, e. The shaft e is mounted in bearings formed
in the side frames a, b of the machine and besides the cam (1) bears the bevel
wheels 1, 2 which perform the same functions as the bevel wheels indicated in the
drawings accompanying the Specification filed in pursuance of the conditions of
the Letters Patent above referred to which are marked with the same letters of
reference. The arm 15 and the arm 16 which is provided with the trumpet 18 are
as illustrated in the accompanying drawing constructed and arranged somewhat
differently from the arms 15 and 16 illustrated in the drawings accompanying the
Specification above mentioned the arm 15 illustrated in the accompanying drawing
being made in the form of a bracket with two parallel members connected at
certain parts so as to form cheeks (2) between which is placed the end of the
arm 16 which embraces the pin employed in the joint 16" and also so as to form a
slot or guide through which another part of the arm 16 passes so as to be guided.
From an inspection of the accompanying drawing it will be obvious that as the
arms 15 and 16 are caused to oscillate horizontally by the action of the crank
pin v and connecting rod 21, the cam (1) being caused to revolve with the same
angular velocity as the disc u the arm 16 bearing upon such cam (1) will be raised
and lowered about the joint 16* in such manner that the eye or trumpet 18 will
be caused to lay the yarns or threads passing through it around the fixed hooks 40
and 40* in a manner similar to that in which the trumpet 18 shown in the drawings
filed with the Specification above referred to operates. In other respects than
those above described the construction and operation of the lower set of parts for
forming warps or yarns or threads into chained or linked warps is similar to that
of the mechanism for chaining or linking warps which is described in the Speci-
fication above referred to. The upper set of parts for forming warps or yarns or
threads into chained or linked warps is similar to the lower in construction and
operation except in that the shaft is mounted in side frames a², b² connected
together by a cross plate d and secured respectively to the side frames a, b in which
the shafte is mounted and motion is transmitted to the shafts & and 14 from the
shaft e and the shaft 14 in a manner which will be hereinafter described instead of by
a pulley corresponding to the pulley (k) and a crank pin, connecting rod and arm
corresponding to the crank pin e, connecting rod 21 and arm 19. The side frames a², b*
are so formed at their lower parts that they may embrace the beadings formed at
the upper parts of the side frames a, b, and are bolted to such side frames a, b.
(3) is a guiding roller and 61, 62 and (11) are rollers. The roller 61 is
covered on its periphery with leather or flannel or woollen or cotton cloth or
other material which will enable such roller and the roller 62 to more efficiently
draw off the yarns or threads or warps to be chained or linked from the bobbins
or beam on which they may have been wound and deliver them to the sets of
mechanism by which they are to be respectively formed into chained or linked
warps. The roller (3) is mounted upon an axle (4) supported in brackets (5)
secured upon side frames (6) connected to the side frames ab of which side
frames (6) one only is shown in the accompanying drawing. The roller 61 is
mounted upon a shaft 60 mounted in brackets 58 which are secured to the side
frames (6). Loose upon the shaft 60 is mounted a pulley receiving rotary motion
from any suitable source of motive power and capable of being slidden for a short
distance in the direction of the axis of such shaft. Fast upon the said shaft 60,
is mounted a disc one face of which is adjacent to the said pulley. Upon the
shaft 60 is mounted a lever formed on the part surrounding the shaft 60 with
suitable cam surfaces which are arranged to act in conjunction with corresponding
cam surfaces formed on the fixed framework of the machine and around the
shaft 60 so that when the said lever is turned a short distance in one direction
around the shaft 60 it will also be moved laterally by the action of such cam

page_text: surfaces so as to press the said pulley against the aforesaid disc mounted fast upon
the shaft 60 so that motion will be transmitted by friction from the said pulley
to the said disc and so to the shaft 60. The attendant in charge of the machine
moves the said lever to and fro around the shaft 60 by means of another lever
formed with a projecting pin engaging with a slot formed in the lever upon which
cam surfaces are formed. The lever by means of which the lever formed with
cam surfaces is moved is so arranged and the lever upon which cam surfaces are
formed is so formed or weighted that when the attendant in charge of the machine
releases the lever by which the lever formed with cam surfaces is moved the
aforesaid lever formed with the cam surfaces will tend to turn so as to allow the
said pulley to move out of contact with the disc aforesaid so that rotary motion
will cease to be transmitted from the said pulley to the shaft 60. This arrangement
of friction driving mechanism being similar to an arrangement often employed in
beaming machines of ordinary construction is not shown in the accompanying
drawing. It is obvious that any other equivalent means may be employed instead
of this arrangement of friction driving mechanism. Fast upon the shaft 60 is
also mounted a pulley (7), around which passes a band (8) which also passes
around a pulley (9) secured upon the shaft (10) fast upon which the roller (11) is
mounted. The shaft (10) mounted in bearings formed in standards (12) secured
to the side frames (6) of which standards (12) only one is shown in the accom-
panying drawing. Upon the shaft 60 is also mounted a pulley 85 around which
passes a belt 86 which is passed around the fast pulley upon the shaft e when
motion is to be imparted to the parts by which the chaining or linking of the yarns
or threads is to be performed and at other times may be caused to pass around the
loose pulley j. The warps or yarns or threads to be formed into chained or linked
warps are conducted from the beam or beams or bobbins on which they may have
previously been wound through any suitable appliances and guides which it may
be desirable to employ to the eye or guide (13) and are thence passed over the
roller (3) under the roller 61 and between such roller 61 and the roller 62.
accompanying drawing the roller 62 is shown as being mounted upon an axle 63
supported in arms (14) which are mounted upon pivots (15) secured in brackets (16)
secured to the side frames (6) and are adapted to receive weights or to be connected
to springs by means of which the roller 62 may be pressed more or less against the
roller 61. The accompanying drawing shows only one of the arms (14), one of the
pivots (15) and one of the brackets (16). After being passed between the roller 61
and the roller 62 the warps or yarns or threads are separated into two portions
one of which is passed through the trumpet 18 and around the fixed hooks of the
lower set of parts for forming warps or yarns or threads into chained or linked
warps while the other of such portions is passed over the roller (11) and through
the trumpet 18 and passed around the fixed hooks of the upper set of parts for

motion is imparted to the shaft 60 the revolution of the roller 61 will cause the
warps or yarns or threads to be drawn off from the beam or beams or bobbins on
which they may have been wound and the warp or yarns or threads which is or are
to pass through the trumpet 18 are delivered thereto and the warp or yarns or
threads which is or are to pass through the trumpet 182 are delivered thereto with
the aid of the roller (11) which is caused to revolve by means of the band (8).
The rollers 61 and 62 and (11) are driven at such speeds that the movements of
the trumpets 18, 18 around the fixed hooks in conjunction with which they work
will not subject the warps or yarns or threads to any tension injurious to such
warps or yarns or threads.
In the
The shaft 14* is connected to the shaft 14 by means of a suitable clutch
coupling (17) so arranged that when it may be desirable the shaft 14 may be
disconnected from the shaft 14 and that when the two shafts 14 and 14 are to be
connected together they may readily be placed and secured in the required positions
relatively to one another. In the clutch coupling (17) shown in the accompanying
drawing, the part (17") is capable of being slidden lengthwise upon the shaft 14

page_text: which is formed with a key or feather engaging with a keyway or groove formed
in the said part (17) of the clutch coupling (17) and the said part (17) is formed
with notches with which may be made to engage projections or teeth formed upon
the part (17) of the clutch coupling (17). The part (17") of the clutch
coupling (17) may be secured in position upon the shaft 14 by means of a set
screw (17).
The shaft m² on which the bevel wheel (20) gearing into the bevel wheel (21)
mounted upon the shaft is mounted and the shaft m upon which is mounted
the bevel wheel (22) gearing into the bevel wheel (23) mounted upon the
shafte are connected together by means of a suitable clutch coupling (24) so
arranged that when it may be desirable the shaft m' may be disconnected from
the shaft m and that when they are to be connected together the shafts m
and m may be readily placed and secured in the required positions relatively
to one another. In the clutch coupling (24) shown in the accompanying
drawing the part (24) is capable of being slidden longitudinally upon the
shaft m which is formed with a key or feather engaging with a keyway or
groove formed in the said part (24) of the clutch coupling (24) and the said
part (24) is formed with notches with which projections or teeth upon the other
part (24") of the said clutch coupling (24) may be made to engage. The part (24°)
of the clutch coupling (24) may be secured in position upon the shaft m³ by means
of a set screw (24°).
The trumpet 18 and the other parts of the upper set of parts for forming warps or
yarns or threads into chained or linked warps are thus caused to operate in
a similar manner to the corresponding parts of the lower set of such parts so that
the warp or yarns or threads delivered to the trumpet 18* by the rollers 61, 62,
and (11) will be formed into a chained or linked warp.
The shaft 14 might be formed in one with the shaft 14 and the shaft m³ might
be formed in one with the shaft m but it is preferable to connect them in the
manner above described by means of clutch couplings or by collars and set screws,
in order that whenever it may be desirable the upper set of parts for forming
warps or yarns or threads into chained or linked warps may be put out of action
whenever its operation may not be required. (27) is a guide by means of which
the chained or linked warps formed by the upper set of parts for forming warps or
yarns or threads into chained or linked warps are prevented from coming into and
being soiled or injured by contact with any of the parts of the lower set of parts
for forming warps or yarns or threads into chained or linked warps. The guide (27)
shown in the accompanying drawing, is formed of a sheet of metal extending in an
inclined position and secured by bolts to the side frames a, b. The guide. (27) is
omitted from Fig. 2 in order that other parts of the machine may be more clearly
indicated.
When the machine illustrated in the accompanying drawing is being employed.
to form two warps or two sets of yarns or threads into chained or linked warps the
two warps or the two sets of yarns or threads are drawn by the rollers 61 and 62 at
the same time from the beam or beams or bobbins on which they may have been
wound and only separated from one another when they have passed between the
rollers 61 and 62 and one warp or set of yarns or threads is required to pass
through the trumpet 18 and the other warp or set of yarns or threads is required to
pass through the trumpet 18%. In the case of two warps which may have been
wound upon one beam and especially in cases in which one of the two warps
wound upon one beam is composed of only a very small number of yarns or threads
or in cases in which it is desired to form into a separate chained or linked warp a
small number of the yarns or threads wound upon a beam together with a larger
warp, the tension to which the yarns or threads are subjected in being drawn off
from the said beam is divided among the entire number of yarns or threads being
drawn off so that there is no danger of the warp which may contain fewer yarns or
threads than the other becoming broken in causing the beam upon which it may
have been wound to revolve. It is thus made possible for a chained or linked

page_text: warp containing only a very small number of yarns or threads to be readily
produced by means of a warp chaining or linking machine.
It is obvious that by employing more than two sets of parts for forming warps or
yarns or threads into chained or linked warps a machine constructed according to
this invention may be made capable of forming any required number of chained or
linked wraps simultaneously and that a third or third and fourth or other set or
sets of such parts may be placed above the first and second and be operated in
a manner similar to that in which the second or upper set of parts for forming
warps or yarns or threads into chained or linked warps which is employed in
the machine illustrated in the accompanying drawing is operated.
It is also obvious that if each or some of the several sets of parts for forming
warps or yarns or threads into chained or linked warps which are employed
according to this invention in conjunction with one set of rollers for drawing off the
warps or yarns or threads from the bobbins or cops or beam or beams on which
they may be wound in readiness for being chained or linked, be constructed
similarly to the lower of the two sets of such parts in the machine illustrated in the
accompanying drawing, so that the trumpet employed in such set of parts receives
motion by means of a connecting rod arranged and operated similarly to the con-
necting rod 21 the several sets of parts for forming warps or yarns or threads into
chained or linked warps which are constructed in this manner, may be placed in any
relative position which may be found convenient.
It is also obvious that in a manner similar to that above described two or more
sets of parts for forming warps or yarns or threads into chained or linked warps
which are each constructed and arranged similarly to the parts employed for such
purpose in the machine illustrated in the drawings, accompanying the Specificatiou
filed in pursuance of the conditions of the Letters Patent above referred to may be
arranged in accordance with the present invention in combination with one set of
rollers for drawing off the yarns or threads from the bobbins or cops or beam or
beams on which they may have been wound in readiness for being formed into a
warp or chained or linked.
As has been explained above a machine arranged in accordance with the present
invention enables two or more warps to be formed into chained or linked warps
simultaneously and in cases in which one or more of the warps being unwound from
a beam in order to be chained or linked is or are small that is to say contains or
contain only a very small number of yarns or threads by causing the power
necessary to cause the beam upon which such warps have been previously wound to
revolve during the unwinding of the warps therefrom to be mainly transmitted by
means of the larger of the two or more warps to be chained or linked renders it
possible for very small warps to be unwound from a beam and chained or linked by
means of a warp chaining or linking machine which has hitherto been impracticable
partly on account of such warps being unable to bear the strains to which they
would have been subjected and partly because in a warp chaining machine as
hitherto arranged the amount of attention required is equally great whether the
warp, being formed into a chained or linked warp contains many or few yarns or
threads so that the cost of attendance in the case of warps containing only small
numbers of yarns or threads has largely prevented such warps from being chained
or linked by machines and hitherto they have usually been chained by hand at a
considerable cost. When a warp.containing only a small number of yarns or
threads and a larger warp are being formed into chained or linked warps by means
of a machine arranged in accordance with this invention the labour on the part of
the attendant is practically no greater than would be necessary were the larger
warp to be chained or linked alone, this invention thus enabling the chaining or
linking of small warps to be accomplished at a very low cost.
A machine constructed according to this invention can also be employed with
advantage in the simultaneous formation of two or more chained warps from yarns
or threads wound upon bobbins placed in a creel or from cops and when so

page_text: employed enables a warp or warps containing only a small number of yarns or
threads to be economically formed and chained or linked by being formed or chained
or linked at the same time as another warp or other warps which may be formed of
a similar or a larger number of yarns or threads.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a machine for chaining or linking warps or for forming warps from yarns or
threads and chaining or linking the same, the combination substantially as and for
