Office of the Commissioners of Patonts on the 22nd February 1882.
JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DRAWING IN
WARP THREADS OR THREADING THEM THROUGH REDDIES," A communication
from abroad by Lewis P. Sherman and Richmond H. Ingersoll of Biddoford in the
County of York and State of Maine and George Moore of Berwick in the County
and Stato aforesaid in the United States of America,
Our Invention consists of an organized Machine embodying certain automatic
devices by means of which the operation of drawing in warp threads is performed
in a very rapid and reliable manner thus effecting an immense saving of time and
labor.
A reed is supported in a vertical position by rests on a rod and adjustable
clamps at the lower ends of a frame attached to the uprights of the framework.
The heddles are hung up within the Machine in a vertical position by means of
hooks placed upon rods adapted to slide longitudinally in bearings at the top of
the framework.
These books fit into the eyes of the top bars of the heddle fraines the lower bars
of these frames having oyes into which fit hooks secured to horizontal rods which
are also moveable in the direction of their length the upper hooks which are kept
in place by collars being provided with screws for raising the upper bars of the
heddle frame to stretch the heddle cords tight and keep them in proper position..

page_text: On the front portion of the frame is a traversing carriage or slide which is fed
intermittently from right to left by means of a feed screw gearing into a sinall
worm wheel so attached to a vertical shaft passing upwards through the traversing
carriage that while it cannot turn independently of the Shaft the latter can have
a slight vertical movement independently of the wheel. The shaft passes through
a post on the carriage and is furnished above the latter with a hand wheel which
is secured to and must turn with the said shaft although the latter can slide in the
wheel to a limited extent. The upper end of the shaft is threaded and adapted to
a hand nut on tightening which the shaft will be locked and the worm wheel
rendered immovable so as to become a nut for the feed screw when the latter has
to traverse the slide the loosening of the nut setting the shaft at liberty when it
has to be used as a means of traversing the slide by hand in which case the worm
acts as a pinion and the feed screw as a rack.
The driving shaft has its bearings in the opposite sides of the framework and
extends under the centre of the traversing carriage from side to side of the machine
On one end of this shaft and loose thereon is a driving pulley and a balance wheel
connected to the pulley, the motion of the balance wheel being communicated to
the driving shaft through the medium of a friction wheel against which tho face
of the balance wheel bears and this friction whool can slide on but must turn with
a short shaft carrying at its inner end a bevel wheel which gears into a similar
wheel on the driving shaft.
The friction wheel can be moved to and fro on the shaft to diminish or increase
the speed of the machine as required. The shaft is provided with a crank handle
so that the machine inay be operated by hand when required.
The lever by which the balance wheel is brought into contact with the friction
wheel is connected to a rod, the latter being connected by an intermediate lever
to a sliding rod having a handle by means of which it may be moved in one
direction to apply the balance wheel to the friction wheel a spring tending to
force the rod in a contrary direction.
A catch lever is pivoted to an arm jointed to a bracket on the framework and a
projection on this catch lover enters a notch in the first named rod where it is
retained by a spring:
On that end of the driving shaft opposite to that which carries the balance-
wheel and outside the frame is a cogwheel and a bevel-wheel connected together
and both loose on the shaft a spring on the latter tending to maintain a clutch
turning with the shaft in gear with the wheels and the clutch being operated
through the medium of an arın on a rod by a hand-lever.
The said cog-wheel gears into an intermediate wheel which in turn drives a larger
cogwheel revolving on a stud projecting from the framework. To the outer face
of this wheel is secured a disk or plate to which is attached a toothed segment the
latter at each revolution of the wheel engaging into a small wheel on the end of
the feed screw to which when the machine is in operation half a revolution is thus
imparted; a single movement of the feed screw taking place at the completion of
each second revolution of the driving shaft, this being necessary in a machine
adapted for operation on two heddles.
If the machine is constructed for operating on three heddles the gearing must be
such that the feed of the carriago would take place at every third revolution of
the driving-shaft and so on:
Against the periphery of the disk bears another disk secured to the feed screw
the last named disk having two curved notches one of which fits around the
periphery of the disk and in this manner the feed screw is locked in position and
prevented from being accidentally turned before the proper time. When however
the toothed segment is brought around to engage the wheel on the feed screw
curved notch in the di-k at the side of the seginent allows the disk of the feed to
revolve after which it is again locked as before by the other disk entering the
next notch:
The warp threads are successively drawn through the eyes of the heddles and

page_text: Dorween the dents of the reed by means of a long needle provided at its outer end
with a hook.
This needle is placed within a tubular casing supported in a frame secured to
the traversing carriage and is attached to a carrier which slides on parallel rods
5 and extends up through a longitudinal slot in the underside of the needle casing
the needle being attached to the carrier in such a manner as to admit of its being
turned upon its axis for the purpose described hereafter.
To the needle carrier is pivoted a rod which is jointed to a link mounted on a
stud and to the said rod is pivoted another rod which is pivoted to a lever the
latter having a pin passing through a slot in an arın and this arun is secured to the
strap of an eccentric at the upper end of a vertical shaft having its bearings in
the slide. This shaft has at its lower end a bevel wheel which gears into another
bevel wheel arranged to slide upon but to turn with the driving shaft as the slide
is traversed being held in place so as to be always in gear with the first mentioned
wheel by a forked hanger extending down from the underside of the slide and thus
as the eccentric is rotated by the driving shaft the needle is reciprocated through
the medium of the connections described a single revolution of the driving shaft
causing the needle to be moved once forward and once back:
To the needle is secured a pin which projects up through a longitudinal slot in
the needle tube the said slot near the end of the tube being so inclined as to turn
the needle on its axis to the extent of a quarter of a revolution in order to bring its
hook on one side just before the completion of its forward movement, thus enabling
the hook to catch the warp thread, after which as it cominences to recede the needle
is turned back to its original position to again bring the hook on the upper side
thereby preventing it from catching the eyes of the heddles and the dents of the
reed as it is driven through them.
At the rear of the traversing carriage there is an extension supporting a carrier
which has a projection with a comparatively sharp bearing edge. In this carrier is a
recess containing an oscillated disk provided with a hook Above this carrier is a
pair of nippers which seize a number of warp threads drag them along the sharp
edge of the projection towards the disk the hook of which seizes one of the warp
threads and inoves it within range of the needle, the latter drawing the thread back
through the heddles and through the reed. Thread after thread is thus operated
on as the slide is fed intermittently and the carrier its disk and nippers traversing
with the slide :-
The warp threads from the beam pass up over a guide rod extending across the
framework and thence between a Stationary bar and a removable bar the latter
being confined in place by inclined guides so that by pressing the bar down the
warp will be clamped tightly.
The entrance to the space between the projection and bearing edge between
which are always some of the warp threads is made flaring for directing the warp
threads. The warp threads are led over a horizontal rod and thence down between
a stationary rod and a removable cloth covered clamping bar held in place by
inclined guides. The bearing odge of the carrier is so situated in respect to the
clamping devices which hold the warp threads that the latter will bear against the
said edge.
The following is the manner in which the warp threads are successively selected
and carried one at a time against the needle into a position to insure their being
caught by its hook so as to be drawn thereby through the eyes of the heddles and
between the dents of the reed.
The projection and the bearing edge hereinbefore described are at such_distance
part as to hold the threads parallel or side by side in a single row and prevent
hem from riding over each other the threads nearest the inner end of the bearing
dge being constantly stretched against upper and lower stops or rests by the
ction of a pair of spring nippers which are pivotted to the carrier and are vibrated
nd alternately opened and closed by mechanism described hereafter the jaws of
hese nippers opening on their descent so as to pass clear of the threads and closing

page_text: thereon on their assent with sufficient friction to take up any slack and produce a
tension or strain on the said threads the upward movement of the jaws in the arc
of a circle tending also to draw the threads against the said stops.
In the underside of the carrier is formed a circular recess which oscillates freely
a flanged disc supported in place upon a stud by means of a nut and an inter-
vening spring this disc being oscillated on the said stud as a centre through the
medium of a connecting rod one end of which is attached to a crank pin on the
underside of the disc and the other end to a lever which is actuated by niechanism
described hereafter. Within this disc is pivotted a curved hook the point of which
projects out through a slot in the side of the disc into such a position in a groove
around the recess as to catch the innermost warp thread of the series between the
projection and bearing edge before described and thus as the said hook is vibrated
with the disc a single thread is selected and separated from the series between the
said projection and edge and carried up against the needle immediately behind
the hook and on the retraction of the needle it will carry back with it the said
warp thread.
In the bottom of the said disk is a curved slot into which the thread enters as
the disk is oscillated, this slot thus causing the thread to be carried inwards
towards the centre of the disk and against the needle as required. Just before
this, however the thread is released by the opening of the nippers so as to avoid
undue strain on, and prevent the breakage of the thread.
In the periphery of the disk is a groove opposite to the groove in the side of the
recess the end of the plate which forins this bearing edge extending into this groove
above the hook which selects the thread thereby preventing the thread from getting
into the space between the disk and wall of the recess and also preventing two
threads from being caught by the hook at the same time. The distance to which
the point of the hook projects is capable of being regulated.
Just before the needle has arrived at the end of its forward movement, it is
brought into contact with a guard plate serving to guide the needle into the exact
position required to insure its receiving and catching the warp thread when
delivered by the hook.
For convenience of construction the projection is provided with a shoe and this
shoe is furnished at its inner end with two small projections the first overlapping
and the second underlapping the oscillating disk and both serving as guards to
prevent the thread from getting in between the disk and the sides of the recess in
which it oscillates The shoe is made adjustable on the projection at the inner end
of the shoe is a small central notch to allow for the passage of the hook. To still
further prevent the liability of the liability of the warp threads becoming crossed
or riding over each other while between the projection and bearing edge and to
straighten or flatten them out a bell crank lever is employed which is pivoted
immediately beneath the projection the upper flattened edge of this lover extending
out and fitting up close to and under the bearing edge. At oach movement of the
curved hook and just before it catches the thread the said lever acted on by a
spring is moved by a bent lever (which is actuated by a spring attached to the
adjacent lever) and drawn down from the bearing edge in contact with the threads
the rubbing action of the edge of the said lever against the tightly stretched
threads thus serving to flatten or straighten them out the point of the hook
catching the thread at a point between the bearing edge and the edge of the said
lever by this device the catching of the wrong thread or of two threads at once is
effectually prevented:
The motion of the driving shaft is communicated to the mechanism connected
with the carrier in the following manner
An inclined shaft carrying at its upper end a bevel wheel gears into a simila
wheel previously referred to on the driving shaft and at the lower end of the said
shaft is another bevel wheel gearing into a bevel wheel on a horizontal shaft a beve
wheel being arranged to slide on but turn with the said shaft and having a grooved
hub which is embraced by a forked hanger connected with the plate of th

page_text: traversing carriage This wheel gears into another bevel wheel at one end of a
shaft which extends towards the rear of the machine and has its bearings in arms
projecting from a bar. At the opposite end of the said shaft is a sinall bevel
wheel which gears into a similar wheel at the lower end of an inclined shaft
extending diagonally through a standard and having its bearings therein :-To the
upper end of this shaft is secured a bevel wheel which gears into a similar wheel
on the end of a horizontal shaft having its bearings in supports on the before
mentioned carrier and having at its opposite end a crank to which is pivoted a
connecting rod attached to a slide which inoves ou a vortical guide secured to the
underside of the said carrier. To the side of this slide is pivoted a bent rod the
upper end of which is pivoted to the nippers the latter through the connections
described being vibrated at the proper time.
The said nippers are composed of a bar pivoted to the carrier and a jaw pivoted
to the bar. This movable jaw of the nippers is connected by a universal joint to a
bell-crank lever pivoted to the carrier and caused to bear against a cain so that
when the can rotates the said jaw will be opened and closed. To the crank of the
shaft on which is the said can is also pivoted another connecting rod the opposite
end of which is attached by a universal joint to the lever which is operated to
produce the desired results.
The mechanism employed for stopping the machine when a warp thread breaks
or when a thread is missed by either the vibrating hook or the needle consists as
follows
A horizontal rock-shaft having its bearings in the frame work and carrying near
one end a crank arm to which is pivoted a rod provided with a wedge adapted to
be introduced between the rod previously referred to and the lever for the purpose
of depressing the latter and withdrawing its projection from the notch in the said
rod thereby allowing a spring to operate the shipper lever and stop the machine.
An arm hung to the frame is vibrated continuously as the machine operates by the
combined action of a cam and a spring and to this arm is jointed a rod passing
through a sleeve pivoted to the arin on the rock shaft Between this sleeve and a
collar on the said rod is a spiral spring so that the rod is at liberty to be reciprocated
when the arm is stationary.
There is a bent arm provided with a collar or hub adapted to slide on but move
with the rock shaft; this collar and arm being caused to inove with the standard
forming part of the slide by a forked plate which fits within an annular groove in
the said collar.
The upper end of the said arın is held back so as to prevent the shaft from being
rocked through the medium of the rod (which is pivotted to tho arin of the rock
shaft) by means of a weighted dog at the end of a shaft which carries at its inner
end a flat plate and against the latter bears the thread when unbroken the thread
keeping the dog in a position to hold the arm back. Should the thread break
however, or not be carried under the plate by the needle the dog will turn by its
own weight aud release the arm when the crank of the rock shaft will be
operated through the medium of the rod the spring being a sufficiently rigid
medium through which to rock the shaft and cause the wedge to operate a lever
and release a rod to cause shipper lever to be actuated by the Spring and the
machine stopped.
As long as the thread is unbroken and remains in contact with the plate the dog
retains the lever of the rock shaft and holds the shaft stationary without being
disturbed by the reciprocating rod :
Each of the heddles is constructed as follows :—
The cords below every eye of the heddle pass round the lower bar but the two
cords of one eye pass up and over one side of the upper bar while the cords above
the next eye pass upwards and over the opposite side of the said bar and this
alternation of the upper cords of the eye is continued throughout the entire
heddle; To the lower bar of each heddle is temporarily attached a bar to

page_text: which are pivoted two links the latter being jointed to another bar forming parallel
bars :
This device is introduced longitudinally between the cords of the heddles and by
moving the bar end wise and thereby raising the same, it will be brought directly
under the eyes of the headles and will cause the faces of each eye to be presented
towards the front of the Machine. Between the cords of each heddle above the
eyes passes a rock shaft the said shaft being adapted to bearings on the
framework. A separating arm is arranged to slide on but rock with the said shaft
and to traverse intermittently in unison with the feed of the carriage and needle:
It should be remarked here that there is a sudden intermittent end wise movement
of the heddles effected in the manner described hereafter:
The function of this oscillating separating arın consists by cooperating with the
end wise movement of the heddles and the traversing of the said separating arm
in unison with the slide in selecting eye after eye of the heddle for presentation to
the needle:
The vibration of each separating arın is intermittent as it hesitates while in a
central position in moving in both directions:
On the return movement of the separating arm it stops midway between the
two limits of its movement for a purpose explained hereafter.
Having now described the selecting and separating functions of the separating
aruns I will proceed to describe other duties which they perform in connection with
other devices: Before the point of the needle reaches the eye of the heddle the
separating arm has pushed the said eye against a finger on a rod referred to hereafter;
and the eye is thus held between the separating arm and finger within range of the
needle which passes through the eye and thence close to the separating arm of the
next heddle without going through one of the eyes of the latter heddle as the nearest
eye to the needle of this heddle has been inoved out of the way of the needle
by a finger in a manner explained hereafter. After the hook of the needle has
soized a warp thread it recedes and drags the thread through the eye of the heddle
and through the reed. After the needle in receding has passed from the eye of
the heddle and dragged the warp thread through the same a finger acting on the
knot at the lower end of the eye moves the said eye from one position to
the other the end of the first named finger yielding in order to permit the eye
to pass. Immediately after reaching this position the fingers move back to their
original positions (it will be seen hereafter that the fingers inove together) and the
eye is now held out of the range of the needle by the first named finger. In the
meantime the separating arm is in a position to keep that eye of the heddle next
to the eye out of the way of the needle and the eye of the heddle and the adjacent
eyes of the same heddle are so far apart that on the next forward movement
of the needle it will pass between these two eyes but through one of the eyes of
the other heddle which eye has been prepared for the passage through it of the
needle in the same manner and by devices similar to those described above as
acting on the eye of the first named heddle.
As regards the detailed construction of the separating arın a finger is pivoted to
one side of the said separating arin the outer edge of this finger being curved and
the lower end provided with a projection which slides in a seginental recess at the
lower edge of the separating arin the movement of the finger on the arın being
restricted by the ends of the recess so that it cannot pass beyond the corners of
the said separating arm:
When the arun is oscillated the finger is practically at rest being confined
between the cords of the heddles and bears thereon, nearly down to the bottom
of the eyes when the separating arm is vibrated to one side to limit of its
movement and by thus bearing on the heddle cords it acts as a guard and effectually
prevents the corners of the arm from catching against the eye next to the eye on
its return movement:
To effect the intermittent sliding movement of the separating arms in unison
with the traverse of the slide and needle three posts are secured at their lower

page_text: ends to the rod and hence are intermittently traversed with the slide and in the
top of each of these posts is a groove. The lower edge of the separating arın
appertaining to the first heddle, is always in the groove of the first post, or that
of the middle post or in the grooves of both of these posts and the separating arm
appertaining to the second heddle is always in the groove of the middle post, or
that of the last post or in the grooves of both of these posts, and hence the
separating arms must traverse on their rock shafts in unison with the intermittent
traverse of the carriage and its needle:
As regards the oscillation of the fingers the one finger is at the upper end of a
rod and the other finger at the upper end of another rod both rods being connected
to a hub on a shaft which has its bearings on the framework of the machine, the
bub with its two rods being arranged to slide on but rock with the said shaft. At
the same time the hub and its arms and finger traverse with the rod connected to
the carriage for a collar which may be adjusted and secured on the said rod has
a plate projecting into a groove in the hub.
There is for each heddle the above described device and two shafts for the two
devices or it there be three heddles three shafts for three devices:
A vertical shaft carries at its upper end a bevel wheel which gears into a similar
wheel above referred to on the driving shaft and to this vertical shaft is also
secured a bevel pinion gearing into a bevel wheel on a horizontal shaft at the
opposite end of which is a wheel gearing into a wheel on a horizontal shaft,
the last named two shafts being supported in bearings on the side of the
framework.
At the rear end of the first of the last named two shafts is a bevel wheel which
gears into a similar wheel on a short shaft carrying at its opposite end two cams
against which bear two rods which are supported near the cains by passing through
holes in a stationary piece the opposite ends of these rods being pivoted to arins
secured to the rock shafts and the rods being inaintained in contact with the cains
by spiral springs which serve to move the shafts in one direction the cains moving
them in the opposite direction, and in this manner the cams and springs produce
at the exact times required, the proper oscillating movements of the fingers as the
hubs are moved along on the shafts as above described.
As regards the oscillation of the separating arms the first of the before named
two shafts carries a bevel wheel which gears into a similar wheel on the lower end
of a vertical shaft carrying at its upper end a bevel wheel which gears into a wheel
on a horizontal shaft supported in bearings on the uprights of the framework.
This shaft carries two scroll cams the groove in each of which is provided with two
straight portions and two double inclines on opposite sides of the cam:
Into these grooves fit the lower ends of two arms extending down from short
shafts forming continuations of other shafts so that as the cams are rotated the
desired rocking movements are alternately imparted to the separating arms the
double inclines of one cam being opposite to the centres of the spaces between
those of the other cam in order that the movements of the two rock shafts and
their soparating arins may alternate, as required.
As regards the endwise reciprocating inotion of the heddles the faces of the
aforesaid cams are provided with projections or tappets which as the cams revolve
are brought into contact with the bent lower ends of two rods pivoted at their
upper ends to studs projecting from two vertical rods which are thus lifted each
time one of the projections striking and passing up out of contact with the end of
its rod. The vertical rods are each pivoted at their upper and lower ends to
rockers these rockers being pivoted upon the opposite sides of supporting pieces
attached to the framework:-The inner flat faces of these rockers fit squarely
gainst toe pieces secured to the ends of sliding rods and thus as the rockers are
Oscillated through the connections described the said rods are moved in the
lirection of their length to operate the heddles in one direction springs returning
hern to their original positions on the reverse movement of the rockers.
Soon after the hooked needle has drawn a warp thread through one of the eyes

page_text: of a heddle and through the reed a revolving finger or arm strikes the thread and
draws it out of the hook of the needle, and casts it over to one side out of the way
thus preventing the needlo from carrying the thread back again on its return
stroke as it might otherwise do:
This revolving finger is attached to the end of a horizontal shaft having its
bearings in the traversing carriage and carrying a bevel wheel gearing into a
similar wheel on the top of a vertical shaft a bevel wheel on the lower end of
which gears into a wheel on the lower shaft of the machine and in this manner the
finger is caused to perform its work of drawing the thread out of the needle at the
proper time, which is when the said point has been drawn back out of the path of
the finger so that the latter will clear it as it rotates:
The above described machino may be made for operating upon two as described
or upon three or more heddles in which latter case a series of autcinatic devices
the same as above described will be required for each heddle:
The gearing by which the driving shaft is connected with the feed scrow will
also require to be changed as a number of strokes of the needle between each
movement of the feed screw and traversing carriage must correspond to the
number of heddles suspended within and operated upon by the machine; and the
relative sizes of the wheels must be such that for two heddles, two revolutions of
the driving shaft will cause the segment to engage with the gear on the end of
the feed screw for three heddles three revolutions of the driving shaft and so on;
the segment having the exact number of teeth necessary to turn the feed screw
and advance the traversing carriage the proper distance to insure the accurate
operation of the needle:
In operating the machine it is necessary that the first two or three eyes of the
heddles at each end should have two warp threads passed through them instead of
This is effected by
one in order to forin the selvage in the usual manner.
operating the clutch at the required time so that the bevel wheel will not be
rotated by the driving shaft thus throwing out of action the various devices for
operating upon the heddles and producing the feed of the carriage until the needle
has drawn two threads instead of one through the oye when the mechanism is
again brought into action to bring the next eye into position, after which it is
again thrown out to cause the second eye to receive two threads and so on, until
the selvage has been drawn on that side when the entire mechanism is thrown into
action and allowed to continue in action until the needle has nearly reached the
opposite end of the heddles when the operation of alternatoly disconnecting and
connecting the mechanisin controlled by the clutch is repeated to cause the selvage
to be drawn at that end of the heddles as required:
Having now explained the construction of the different parts composing the
machine and the operation of different features I will now describe in brief terms
the operation of the principal operating parts in relation to each other. Let it be
supposed that the needle has reached the limit of its rearward movement that the
scrow has fed the traversing carriage to the desired extent and that the needle is
about to commence its forward movement. Tho warp throad about to be seized
by the needle is with others between the jaws of the nippers (which however have
not yet seized the thread) and against the bearing edge the point of the hook of
the disk is at its greatest distance from the thread which it has to subsequently
seize the separating arm appertaining to the one heddle is in the act of pushing the
eye of the said heddle against the finger, which is stationary, and the separating
arm appertaining to the other heddle is quiescent in its central position where it
keeps the eyes of the said heddle away from the course of the needle:
We will now suppose that the needle is in the act of moving forward and has
passed through the reed. Before its point reaches the eye of the one heddle the
separating arm of that heddle has completed its duty and is stationary in its
central position while it holds the eye of the said heddle against the finger so that
it will be in a proper position to receive the point of the needle. In the meantime

page_text: the separating arm and fingers appertaining to the other heddle are in the act of
perforining the duty of separating the eye last threaded of that heddle froin the
other eyes so as to clear the way for the needle and prevent it from passing
through any eye of the said heddle:
The needle having passed through the reed through the eye of the one heddle
and between the threaded eye and next eye of the other heddle is approaching the
limit of its forward movement. Before it reaches this point however the nippers
have seized a number of threads including that destined to be caught by the hook
of the needle and drawn the threads ipward as well as laterally against the fingers
so that the first thread of the series will be pressed against the periphery of the
oscillating disk and in a position to be seized by the hook of the said disk.
When the needle has reached or very nearly reached the limit of its forward
movement the disk suddenly turns to such an extent that its pointed hook seizes
the first warp thread and drags it into the curved slot of the disk and against the
needle which had turned on its axis before reaching this point. The needle no
sooner reached the limit of its forward movement than it commences to return in
doing which its hook catches the warp thread and the disk turns back so that its
hook loses control of the thread which is now drawn away by the receding needles
from between the rod and the felt of the bar and away from the other warp threads
through the last nained heddle without passing through one of its eyes through
the eye of the first named heddle and through the reed after which the thread is
removed from the needle by the hook:
While the needle is in the act of thus roceding, an eye of the other heddle is
being prepared by the devices and movements above described for receiving the
needle during its next forward movement and the eyes of the first heddle are being
so arranged in the manner and by the appliances described that during the next
forward movement of the needle it will pass between eyes and not through an eye
of the said heddle.
When the needle has arrived or nearly arrived at the limit of its rearward
movement the carriage is fed to the desired extent and a repetition of the above
described operations takes place :
According to a modified arrangement of mechanisin for operating on the heddle
threads and eyes, the shafts previously described as passing through the heddles
and the separating arms which operated on the eyes of the heddle threads as setforth
in the foregoing description are dispensed with as also is the fraine composed of
the parallel bars :
Another bar takes the place of the bar which is connected with the traversing
carriage and needle in the previous arrangement and to this are secured two stands
the tops of which are above the eyes of the heddle cords :-
The mechanism for operating on one heddle is as follows and is duplicated for
the other heddle or beddles.
Adjoining the said stands and having their upper hearings therein, are the
vertical shafts the former onch carrying a hook, these two hooks act on the threads
of one heddle, one on one side and the other on the opposite side of the same
explained hereafter:
The lower ends of the two shafts are attached to but can oscillate in a cross bar
and an intermittent vertical reciprocating motion is imparted to this cross bar,
shafts and books from the shaft by an eccentric or equivalent ineans. An inter-
mittent scillating inovement (not simultaneous) is imparted to the hooks by a
cam and bell crank lever connected to one of the shafts the said arm being confined
vertically and the shaft being arranged to slide in but oscillate with the arın.
Another cam serves to impart an oscillating rovement to the other shaft.
Two levers are pivoted to the bar their lower arms being operated by a cain
wheel.
The one lover has two upper arms the one terminating at the top in a finger
and the other arm having guides for a rod the lower end of the latter having an
arm with which a pin on the cam wheel comes in contact at intervals as the shaft

revolves. At the upper end of the said rod is a jaw having an elongated eye. The
second lever has a single arm terminating in a jaw which has also an elongated
eye-There is an intermittent vertical and simultaneous reciprocating movement
of the two hooks, an intermittent oscillation of the said hooks at different intervals,
an intermittent vibration of the finger; an intermittent oscillation of the jaw
always in the same plane; an intermittent vibration of the other jaw simultaneously
with the vibration of the finger, and a sudden lateral oscillation of the jaw.
should be understood that there is a spring which moves the jaw inwards after it
has been moved outwards Suppose that the two hooks have been elevated and
the points of both hooks are opposite the space between the cords of the heddlo,
when the hooks have reached this position, a movement, is imparted to the slide
and reciprocating needle and consequently to the entire mechanism above described,
the points of the book consequently entering the space between the said cords.
As the hooks descend the first cord will be separated from the next cord and by
the time the hooks have reached the limit of their downward inoveinent the one
hook will have released the one cord while the other hook retains the other cord
and holds the said cord back as well as all the succeeding cords :
The one jaw is moved back and the other jaw moved outwards.
At this point takes place the sudden end wise reciprocating movement of the
heddle referred to in the general description of the machine; and this shakes the
one cord free from the other cord should there be a disposition of one cord to
adhere to the other The one cord and its eye are now in such a condition that
when the one jaw resumes its former position and the other jaw is released so as
to spring back the eye will be so held by the jaws that the needle will pass
through the said eye. The elongated openings in the jaws prevent the eye of the
heddle cord from being closed. After the needle has drawn the warp thread
through the eye of the heddle cord and its point is clear of the jaws, the one jaw
is moved outwards and simultaneously the finger is moved in the same direction
and pulls the eye away from the path of the needle, the jaw yielding and
permitting this movement of the eye of the heddle cord. Immediately after this
à repetition of the above described movements takes placo.
The Improvement in the heddle holder consists as follows;-The upper bar of
the heddle being furnished with two eyes, a threaded shaft has its bearings in the
frame of the machine and is adapted to two nuts each of which is connected to an
eye by an adjustable screw.
The lower bar of the heddle is connected by precisely similar devices to nuts on
a lower screw shaft.
These screw shafts are geared together so that the nuts of the upper and lower
screw shafts can be traversed simultaneously and the heddle thereby adjusted.

page_text: D. E represent the heddles which are hung up within the machine in a vertical
position by means of hooks c placed upon rods à adapted to slide longitudinally in
bearings at the top of the framework.
These hooks c fit into the eyes f of the top bars a of the heddle frames, the
lower bars g of these frames having eyes h into which fit hooks i (Figures 6 and 28) 5
secured to horizontal rods k which are also movable in the direction of their length
in suitable bearings in the framework, the upper hooks c which are kept in place
by collars 45 being provided with thumb screws / by means of which the upper
bars of the heddle fraines may be raised to stretch the heddle-cords tight and keep
thein in their proper position; the eyes f and h being those by which the heddles
are suspended within the loon.
On the front portion of the frame and adapted to suitable guides on the saine,
is a traversing carriage or slide F, which is fed intermittently from right to left by
means of a feed scrow G (Figure 1) adapted to suitable bearings on the framework
and extending entirely across the machine.
This feed screw G goars into a small worm wheel H (Figure 8) so attached to
a vertical shaft n passing upwards through the slide F that while it cannot turn
independently of the shaft, the latter can have a slight vertical movement
independently of the wheel. The shaft n passes through a post p on the carriage
and is furnished above the latter with a hand wheel I which is secured to, and
must turn with the said shaft, although the latter can slide in the wheel to a
limited extent. The upper end of the shaft is threaded and adapted to a hand
nut on tightening which the shaft will be locked, and the worm wheel rendered
immovable, so as to become a nut for the scrow G, when the latter has to traverse
the slide, the loosening of the nut setting the shaft at liberty when it has to be
used as a means of traversing the slide by hand in which case the worin acts as a
pinion and the feed screw as a rack.
I is the driving shaft which has its bearings in the opposite sides of the frame-
work and extends under the centre of the slide F, from side to side of the machine.
On one end of this shaft, and loose thereon, is the driving pulley M. (Figures 1, 5
and 7) also a balance wheel N, made in one piece with or otherwise connected to
the pulley, the motion of the balance wheel being communicated to the driving
shaft through the medium of a friction wheel q against which bears the face of
the balance wheel N and this friction wheel can slide on, but must turn with a
short shaft carrying at its inner end a bevel wheel & which gears into a similar
wheel on the driving shaft (figure 5).
2"
The friction wheel q can be moved to and fro on the shaft by a hand lever a¹ to
diminish or increase the speed of the machine as required. The shaft is provided
with a crank handle 52 so that the machine may be operated by hand when
required.
The lever P by which the balance wheel N is brought into contact with the
friction wheel 7 is connected to a rod b the latter being connected by an inter-
mediate lever to a sliding rod c' having a handled by means of which the rod c
may be moved in one direction to apply the balance wheel to the friction wheel a
spring tending to force the rod in a contrary direction.
It will be seen on referring to Figures 7, 23 and 27 that a catch lover 40 is
pivoted to an arm 41 jointed to a bracket on the framework and that a projection e¹
on this catch lever enters a notch in the rod 6' where it is retained by the action
of a spring 42.
The object of this mechanism will be explained hereafter.
that which carries the balance
On that end of the driving shaft opposite t
wheel, and outside the frame is a cog-wheel g' also a bevel-wheel h¹ formed in the
same piece with or otherwise connected to the said wheel g¹ and both loose on the
shaft, a spring on the latter tending to maintain a clutch turning with the shaft
in gear with the wheels, and the clutch being operated through the medium of a
arun on a rod by a hand lever ¹ (Figure 2).
The wheel g¹ gears into an intermediate wheel m³ which in turn drives a large

page_text: cog-wheel n' revolving on a stud projecting from the framework (Figure 3). To
the outer face of the wheel n' is secured a disk or plate p¹ (Figure 18) to which is
attached a toothed segment q¹ the latter at each revolution of the wheel n'
engaging into a small wheel o' on the end of the feed screw G to which when the
machine is in operation half a revolution is thus imparted; a single movement of
the feed screw taking place at the completion of each second revolution of the
driving shaft L this being necessary in a machine adapted for operation on two
heddles.
If the machine is constructed for operating on three heddles the gearing must be
such that the feed of the carriage would take place at every third revolution of the
driving shaft and so on.
Against the periphery of the disk bears a disk e' secured to the feed screw G
the disk s having two curved notches 53 one of which fits around the periphery
of the disk p (Figures 3 and 18) and in this manner the feed screw is locked in
position and prevented from being accidentally turned before the proper time,.
which would produce derangement of the parts and imperfect work or breakage.
When however the segment q' is brought around to engage the wheel of a curved
notch in the disk pl at the side of the segment allows the disk &¹ to revolve after
which it is again locked as before by the disk p¹ entering the next notch 58.
The warp threads w' are successively drawn through the eyes (Figure 28) of the
heddles and between the dents of the reed B by means of a long needle Q
(Figures 4, 5 and 6) provided at its outer end with a hook b².
This needle is placed within a tubular casing R supported in a frame secured to
the slide F, and is attached to a carrier c² which slides on the parallel rods d² and
extends up through a longitudinal slot 46 in the underside of the casing R the
needle being attached to the carrier in such a manner as to admit of its being
turned upon its axis for a purpose described hereafter.
To the needle carrier c is pivoted a rod e' (Figure 5) which is jointed to a link f
mounted on a stud g² and to the rod e² is pivoted another rod h* which is pivoted
to a lever i², the latter having a pin passing through a slot in an arm k² and this
arın is secured to the strap of an eccentric at the upper end of a vertical shaft m
having its bearings in the slide. This shaft has at its lower end a bevel wheel n'
which gears into a bevel wheel p² (Figure 7) arranged to slide upon, but to turn.
with the driving shaft L as the slide is traversed, the wheel p² being held in place
so as to be always in gear with the wheel n by a forked hanger extending down
from the underside of the slide and fitting within a groove in the hub q² of the
wheel p² (Figure 7) and thus as the eccentric is rotated by the driving shaft L the
needle Q is reciprocated through the medium of the connections described a single
revolution of the driving shaft causing the needle to be moved once forward and
once back.
To the needle Q is secured a pin 82 (Figure 6) which projects up through a
longitudinal slot in the tube R the said slot, near the end of the tube, being so
inclined as to turn the needle Q on its axis to the extent of a quarter of a
revolution, in order to bring its hook on one side just before the completion of its
forward movement thus enabling the hook to catch the warp thread w¹ after
which as it commences to recede, the needle is turned back to its original position
to again bring the look on the upper side, thereby preventing it from catching the
eyes of the heddles and the dents of the reed as it is driven through them.
It will be advisable to give here a general explanation of the action of the
reciprocating and intermittently traversing needle Q in connection with other
devices so that the detailed description given hereafter may be more easily
understood.
Figure 36 is a perspective outline drawn without any regard to detailed con-
struction and in this figure F is the intermittently fed slide and Q the reciprocating
needle above referred to.
At the rear of the slide there is an extension, consisting in the present instance
of a bar W and a nost. U to the top of which is attached a carrier T the latter

page_text: Above
having a projection with a comparitively sharp bearing edge d³. In the same
carrier T is a recess containing an oscillated disk provided with a hook C¹.
the carrier T is a pair of nippers A' which seize a number of warp threads drag
them along the sharp edge of the projection d³ towards the disk, the hook of which
seizes one of the warp threads and moves it within range of the needle, the
latter drawing the thread back through the heddles, and through the reed-Thread
after thread is thus operated on as the slide is fed intermittently in the direction
of the arrow and the carrier 'T' its disk B and nippers A traversing with the slide.
The bearing edge d' which is a vital part of the machine is forined in the present
instance on a plate on blade do secured to the carrier.
There is a projection on the carrier T the object of which will be explained
in the detailed description given hereafter.
S (Figures 1, 2, 3, 4 and 6) is the warp beam, the journals of which rest in
suitable supports secured to the floor, or to the framework, the beam being
prevented from unwinding by any suitable device.
The warp threads w¹ from this beam pass up over a guide rod ² extending
across the framework, and thence between a stationary bar w and a removable
bar as the latter being confined in place by the inclined guides 63, of the frame so
that by pressing the bar down, the warp will be clamped tightly and prevented
from slipping.
Some of the warp threads are always between the projection c³ and bearing
edge (Figures 6, 12 and 13) and as the threads are removed, other warp threads
take their places against the bearing edge d of the carrier T while the latter is
traversed with the slide and needle.
The entrance to the space between the projection c³ and bearing edge, d³ is made
flaring by rounding the said projection and bearing edge so that as the carrier T
is traversed the warp threads will be directed into the said space. The warp
threads are led over a horizontal rod and thence down between a stationary rod
on the bar fs and a removable clamping bar gs held in place by inclined guides, h³
on the framework, which cause the said bar g³ when it is pushed down, to be
wedged against the rod f³. The inner side of the bar g³ which presses against the
warp threads, is covered with felt, cloth or equivalent material 35 to allow each
thread to be independently withdrawn by the needle Q without disturbing any of
the adjacent threads. The bearing edge d³ of the carrier T is so situated in respect
to the clamping devices which bold the warp threads, that the latter will bear
against the said edge d³ in other words the said bearing edge is traversed in a
direction parallel with, but at a short distance in front of the row of warp threads.
I will now describe the manner in which the warp threads w³ are successively
selected and carried one at a time against the needle Q into a position to insure
their being caught by its hook be so as to be drawn thereby through the eyes of
the heddles, and between the dents of the reed.
h³
to
The projections and the bearing edge & are at such distance apart as to hold
the threads parallel or side by side in a single row and prevent them from riding
over each other (Figure 12) the threads nearest the inner end of the bearing edge
being constantly stretched against the upper and lower stops or rests
(Figure 6) by the action of a pair of spring nippers A' which are pivoted at
the carrier T and are vibrated and alternately opened and closed by mechanisin
described hereafter, the jaws of these nippers opening on their descent so as to pass
clear of the threads and closing thereon on their ascent with sufficient friction to
take up any slack and produce a tension or strain on the said threads, the upward
movement of the jaws in the arc of a circle having its centre attending also to
draw the threads against the stops ik (Figure 2).
In the underside of the carrior T is formed a circular recess m (Figures 10
and 11) into which is fitted snugly but so as to oscillate freely, a flanged disk B¹
the latter being supported in place upon a stud u by means of a nut p' and an
intervening spring 9³ this disk being oscillated on the said stud n³ as a centre,
through the inedium of a connecting rod 7-8 one end of which is attached to a

page_text: crank-pin on the underside of the disk and the other end to a lever to which is
actuated by mechanisin described hereafter.
Within this disk b', is pivoted a curvad hook C (Figures 12 and 14) the point
of which projects out through a slot in the side of the disk, into such a position as
to catch the innermost warp thread of the sories between the projection and
bearing edge and thus as the hook C is vibrated with the disk B₁ a single
thread is selectel and separated from the series, and carried up against the needle Q
immediately behind the hook thereof (Figure 14) the needle having been, just
previous to the movement of, the hook C advanced into the proper position to
receive the throad, and turned so that its hook 62 will be presented on the side
against which the thread is stretched by the hook C', honce on the retraction_of
the needle Q it will carry back with it a warp thread.
In the side of the recess ³ is an annular groove w into which the point of the
hook C, projects, and in which it moves; this groove thus allowing the point
of the hook to project out to a sufficient distance to enable it to catch the
thread.
In the bottom of the disk B is a curved slot 58 into which the thread enters as
the disc is oscillated this slot thus causing the thread to be carried inwards toward
the centre of the disk, and against the needle Q as required. Just before this,
however, the thread is released by the opening of the nippers A' so as to avoid
undue strain on, and prevent the breakage of the thread.
In the periphery of the disk B is a groove at opposite to the groove w in the
side of the recess m³, the end of the plate 10 which forms this bearing edge d³
extending into this groove at above the hook C₁ thereby preventing the thread
from getting into the space between the disk B' and wall of the recess m³ and also
preventing two threads from being caught by the hook C at the same time.
The distanco to which the point of the hook C₁ projects is regulated by a
screw 6 (Figure 21) or other equivalent device as is necessary for coarser or finer
threads, so that but a single thread may be seized at a time, the screw 6 having a
conical point which bears against the inclined edge of the hook C' (Figure 21) and
the spring us for pressing the book against the screw.
Just before the needle Q has arrived at the end of its forward movement it is
brought into contact with a guard plate c (Figure 14) secured to the underside of
the carrier T, this guard serving to guide the needle into the exact position
required to insure its receiving and catching the warp thread when delivered by
the hook C, the needle being thus supported and held up to its place against any
tendency to spring to one side into such a position that it will miss a thread.
For convenience of construction the projection 3 is provided with a shoe d' and
this shoe is furnished at its inner end with two small projections e, f the first
overlapping and the second underlapping the oscillating disk B' and both serving
as guards to provent the throad from getting in between the disk and the sides of
the recess m³ in which it oscillates. The shoe d is made adjustable on the
projection by set screws as shewn so that it can be moved nearer to or further
from the bearing edge d³, as the thickness of the warp threads may suggest.
At the inner end of the shoe 4, (Figures 15 and 16) is a small central notch g'
to allow for the passage of the hook C. so that the thread about to be seized by
the hook may remain between the projection c³, and bearing edge ď, up to the
time of seizure.
To still further prevent the liabilty of the warp threads becoming crossed or
riding over each other while between the projection 3. and bearing edge ³. and to
straighten or flatten them out we employ a holl crank lever h. (Figures 13 and 22.)
which is pivoted immediately beneath the projection, d³. the upper flattened
edge 60 of the lever h* extending out and fitting up close to and under the bearing
edge d
At each movement of the curved hook C¹, and just before it catches the thread,
the lever . (Figures 10 and 13.) acted on by a spring 39, is moved by a bent
laver at which is actuated by a spring 14. attached to the adiacent lever .

page_text: By this movement of the lever *. its edge, 60, is drawn down from the bearing
edge . in contact with the threads the rubbing action of the edge 60 against the
tightly stretched threads thus serving to flatten or straighten them out if
accidentally crossed, the point of the hook C. catching the thread at a point
between the bearing edge. and the edge, 60, of the lever h.; by this device 5
the catching of the wrong thread or of two threads at once is effectually
prevented.
'
I will now describe the manner in which the motion of the driving shaft Lis
communicated to the mechanism connected with the carrier T.
D is an inclined shaft. (Figures 2, 3 and 4,) carrying at its upper end a bevel 1
wheel gearing into a similar wheel, (Figure 2) previously referred to on the
driving shaft; and at the lower end of the said shaft D. is another level wheel m'.
gearing into a bevel wheel n. on a horizontal shaft E., a bevel wheel p. being
arranged to slide on but turn with the said shaft and having a grooved hub which
is embraced by a forked hanger connected with the plate 59 of the slide F, 1
(Figure 1.)
This wheel p. gears into another bevol wheel q'. at one end of a shaft, which
extends towards the rear of the machine and has its bearings in arms projecting
from the bar W (Figures 2 and 4.)
At the opposite end of the shaft r. is a small bevel wheel st. which gears into a
similar wheel s. at the lower end of an inclined shaft G'. extending diagonally
through the standard U and having its bearings therein. To the upper end of the
shaft G is secured a bevel wheel . which gears into a similar wheel w. on the
end of a horizontal shaft a. having its bearings in supports on the carrier T and
having at its opposite end a crank 6. to which is pivoted a connecting rod, c., the
lower end of the latter being attached to a slide which moves on a vertical
guide . secured to the underside of the carrier T. (Figures 2, 4, 9 and 10.)
To the side of the slide is pivoted a bent rod (Figures 2, 4 and 7,) the upper
end of which is pivoted to the nippers A¹, the latter, through the connections
described, being vibrated at the proper time.
The nippers are composed of the bar " pivoted to the carrier T and the jaw g³.
pivoted to the bar. This movable jaw gs. of the nippers is connected by a universal
joint to the bell-crank lever, h., pivoted to the carrier '1', and caused to bear against
a cam . by a spring . on the shaft 5. so that when the cam rotates the said
jaw g. will be opened and closed (Figures 9 and 11.)
To the crank, b, of the shaft a³, is also pivoted another connecting rod, m³., to
the opposite end of which is attached by a universal joint +7 to the lever 3. which
is thus operated at the proper times to produce the desired results.
I will now proceed to describe the mechanisin employed for stopping the machine
when a warp thread breaks or when a thread is missed by either the vibrating
Look C. or the needle Q.
His a horizontal rock-shaft, (Figuros 2, 4, 6, 24 and 27,) having its bearings in
the frame work and carrying near one end a crank arm, n., to which is pivoted a
rod the opposite end of which is provided with a wedge qs. (Figures 23 and 27,)
adapted to be introduced between the rod b. previously referred to and the lover 40,
(Figure 7,) for the purpose of dopressing the latter and withdrawing its pro-
jection, e, from the notch in the said rod, b. thereby allowing the spring f' to
operate the shipper lever P and stop the machine.
An arm w, hung to the frame, (Figures 4, 24 and 27,) is vibrated continuously
as the machine operates by the combined action of a cam b'. on the shaft E. and a
spring, a, and to this arin is jointed a rod t. passing through a sleeve, s pivoted
to the arun r. on the shaft H₁ between the sleeve and a collar on the rod t.,
intervenes a spiral spring, u³., so that the rod is at liberty to be reciprocated when
the arm rs. is stationary.
11. (Figure 2,) is a bent arm provided with a collar or hub c. adapted to slide on
but move with the rock-shaft H., this collar and arm I'. being caused to move with

page_text: the standard, U, forming part of the slide E by a forked plate d". which fits within
an annular groove in the said Collar.
The upper end of the arm I'. is held back so as to prevent the shaft H¹. from
being rocked through the medium of the rod t. by means of a weighted dog e. at
the end of the shaft. which carries at its inner end a flat plate go, and against the
latter bears the thread when unbroken, the thread keeping the dog e. in a position
to hold the arın I'. back.
Should the thread break however or not be carried under the plate gs. by the
needle Q, the dog e. will turn by its own weight and release the arm I' when the
crank will be operated through the medium of the rod t. the spring u being a
sufficiently rigid medium through which to rock the shaft and cause the wedge q
to operate the lever 40 and release the rod b₁ when the shipper lever will be
actuated by the spring fl and the machine stopped.
As long as the thread is unbroken and remains in contact with the plate q' the
dog e' retains the lever I' and holds the shaft stationary without being disturbed
by the reciprocating rod t.
While it is preferred to employ the stop motion which I have described above
other devices may be used for stopping the inachine when the thread breaks.
I will now proceed to describe the heddles and the manner in which their eyes
are selected and separated one by one in proper order and held in position for the
passage of the hooked needle Q
Each of the heddles D, E, is constructed in the manner shown in the perspective
view Figure 29 in which however the eyes and heddle-cords are arranged at a
much greater distance apart than in the actual heddle in order that the description
may be more readily understood.
The cords below every eye of the heddle pass round the lower bar g but the two
cords all of one eye 62 (Figure 29) pass up and over one side of the upper bar e
while the cords a12 above the next eye 63 pass upwards and over the opposite side
of the said bare and this alternation of the upper cords of the eye is continued
throughout the entire heddle. This heddle is of the kind made by machinery and
is in common use.
To the lower bar of oach heddle is temporarily attached by means of dowel
pins or otherwise a bar (Figures 25 and 28) to which are pivoted two
links me the latter being jointed to a bar n part of which is shown in Figure 30.
This device is introduced longitudinally between the cords of the heddles in the
Inanner best observed in Figure 30 and by moving the bar n' endwise and
thereby raising the same it will be brought directly under the eyes of the heddles
(Figures 28 and 30) and will cause the faces of each eye to be presented towards
the front of the machine.
Between the cords of each heddle above the eyes passes a rock shaft pe in the
manner shown in Figure 28 and inore clearly in Figures 30 and 35 the said shaft
being adapted to bearings on the framework these bearings and devices for actuating
the rock shaft being described hereafter.
A separating arm'q" shown in perspective in Figures 20 and 30 is arranged to
slide on but rock with the shaft p and to traverse intermittently in unison with
the feed of the carriage and needle.
It should be remarked here that there is a sudden intermittent end wise movement
of the heddlos effected in the manner described hereafter.
I will now explain that function of this oscillating separating arm which consists
by co-operating with the end wise inoverment of the heddles and the traversing of
the said separating arm in unison with the slide F in selecting eye after eye of the
heddle for presentation to the needle.
The vibration of each separating arm is intermittent as it hesitates while in a
central position in moving in both directions.
In Figure 35 the separating arm 9' appertaining to the heddle D has reached
the limit of its movement in the direction of the arrow and in moving to this
position has passed away from the eye 62 of which a¹ are the upper cords at the

page_text: same time the separating arm q' keeps back the eye 63 and consequently all the
other eyes whether their upper cords pass on one side or the other of the upper
bar for if the eye 63 be kept back none of the other eyes can pass it.
Just as the separating arın q was leaving the eye 62 there was a sudden short
reciprocating endwise movement of the heddle which shook the eye 62 free from
the other eyes as there is sometimes a tendency of the cords of the eyes to adhere
to each other.
On the return movement of the separating arm in the direction contrary to that
pointed out by the arrow (Figure 35) it stops midway between the two limits of
its movement for a purpose explained hereafter and then completes its movement
in a direction contrary to that pointed out by the arrow in doing which it leaves
the eye 63 holding all the others back and another end wise movement of the heddle
frees the said eye 63 from the other eyes.
Having now described the selecting and separating functions of the separating
arms I will proceed to describe other duties which they perform in connection with
other devices.
In Figure 30 the needle Q is approaching the heddle D in the direction of its
arrow and the arm q* of the heddle is stationary but about to move in the direction of
its arrow and separates the eye 62 of the heddle from the remaining eyes Before the
point of the needle Q reaches the eye 62 of the heddle however the separating arm
9 has pushed the said eye 62 against a finger s on a rod to (Figure 31) referred to
hereafter and the eye 62 is thus held between the separating arm and finger
within range of the needle Q which passes through the eye and thence close
to the separating arm 9º of the next heddle E without going through one of the
eyes of the latter heddle as the nearest eye to the needle of this heddle has been
moved out of the way of the needle by a finger 67 in a manner explained hereafter.
After the hook of the needle has seized a warp thread it recedes and drags the
thread through the eye 62 of the heddle D and through the reed.
After the needle in receding has passed from the eye 62 of the heddle D and
dragged the warp thread through the same the finger or acting on the knot at the
lower end of the eye 62 moves the said eye from the position shewn in Figure 31
to that shewn in Figure 32 the end of the finger 8. yielding in order to permit
the eye to pass from one position to the other.
Immediately after reaching the position 32 the fingers and by move back to
their original positions Figure 33 (it will be seen hereafter that the fingers move
together (and the eye 62 is now held out of the range of the needle by the finger_s*.
In the meantime the separating arın q' is in a position to keep that eye of the
heddle next to the eye 62 out of the way of the needle and the eye 62 of the
heddle D and the adjacent eyes of the same hoddle are so far apart that on the
next forward movement of the needle it will pass between these two eyes but
through one of the eyes of the heddle E which eye has been prepared for the
passage through it of the needle in the same manner and by devices similar to
those described above as acting on the eye 62 of the heddle D.
It will thus be seen that during one stroke or forward and rearward movement
of the needle it passes through the eye of one heddle D and between the eyes of
the other heddle E and drags a warp-thread through the course it has pursued and
that during the next stroke of the needle it passes through the reed between the
eyes of the heddle D through one of the eyes of the heddle E and drags another.
warp-thread through this course so that a warp-thread is drawn through an eye
of one heddle and through the reed and the next warp thread through an eye of
the other heddle and through the reed and this alternation is continued until a
warp-thread has been passed through every eye of both heddles.
As regards the detailed construction of the separating arm of. it will be observed
on reference to the perspective view Figure 20 that a finger c is pivotted to one
side of the said separating arm the outer edge of this finger being curved and the
lower end provided with a projection which slides in a seginental recess at the

page_text: lower edge of the separating arm the movement of the finger on the arm being
restricted by the ends of the recess so that it cannot pass beyond the corners & of
the said separating arro.
When the arm q is oscillated the finger is practically at rest being confined
between the cords of the heddles and bears thereon nearly down to the bottom of
the eyes when the separating arm is vibrated to one side to the limit of its move-
ment and by thus bearing on the heddle cords it acts as a guard and effectually
prevents the corners e' of the arm q* from catching against the eye next to the
eye 62 on its return movement.
As regards the finger 8' it is best to make it in the manner illustrated by
Figure 34 that is to provide it with a light spring projecting beyond the rigid
portion of the finger and bearing against the finger b. so that when an eye of the
heddle has to pass from the position 31 to the position 32 the spring will readily
yield The finger s however may be constructed in a different manner so as to
yield as described.
In order that the several operations above described may be effectually per-
formed it is essential that there should be the following movements of the different
parts referred to.
First. A reciprocating movement of the needle and the intermittent traversing
of the same with the slide F The mechanism for effecting these movements has
been already described.
Second. The intermittent traversing of the carrier T and the devices attached
thereto in unison with the feed of the slide this together with mechanism for
operating these devices has also been explained.
Third. The intermittent sliding movement of the separating arins in unison with
the traverse of the slide and needle.
Fourth. The oscillating movement of the fingers and b' :
Fifth. The oscillating movement imparted to the separating arms
Sixth. The intermittent endwise reciprocating movement of the heddles.
I will now proceed to describe the inechanisin employed for effecting the third
fourth fifth and sixth movements
As regards the third movement the intermittent sliding motion of the separating
arms it will be observed that three posts 7 (Figure 6 are secured at their lower
ends to the rod W and hence are intermittently traversed with the slide F and in
the top of each of these posts is a groove 65 as shown in Figure 6 and also in
Figure 28 in which however but two posts and one heddle are shown.
The lower edge of the separating arm 9 appertaining to the first heddle D is
always in the groove of the first post or that of the middle post or in the grooves
of both of these posts and the separating arm appertaining to the second heddle E
is always in the groove in the middle post or that of the last post or in the grooves
of both of these posts and hence the separating aruns must traverse on their
rock shafts in unison with the intermittent traverse of the carriage F and its
needle Q
As regards the fourth movement the oscillation of the fingers it will be observed
on reference to Figures 26, 28, 31, 32 and 33 that the fingers is at the upper end
of a rod t and the finger 67 at the upper end of a rod a both rods being connected
to a hub u. on the shaft w which has its bearings on the framework of the
machine the hub with its two rods being arranged to slide on but rock with the
said shaft At the same time the hub and its arms and fingers traverse with the
rod W connected to the carriage for a collar (which may be adjusted on the said
rod W and secured after adjustment) has a plate 3. projecting into a groove in the
hub us Figure 26.
Thero is for each heddle the above described device and two shafts w
(Figure 6)for the two devices or if there be three heddles three shafts for three devices.
A vertical shaft (Figures 3 and 7) carries at its upper end a bevil wheel
which gears into a similar wheel h* above referred to on the driving shaft L and to
this shaft is also secured a bevel pinion gearing into a bevelled wheel m

page_text: on a horizontal shaft n' at the opposite end of which is a wheel p' gearing into a
wheel q' on a horizontal shaft the shafts n and being supported in suitable
bearings on the side of the framework A.
At the rear end of the shaft is a bevel wheel 67 which gears into a similar
wheel on a short shaft w' carrying at its opposite end two cars as against which
bear two rods be (Figure 17) which are supported near the cams by passing through
holes in a stationary piece the opposite ends of these rods being pivoted to
arms secured to the rock shafts w. and the rods being maintained in contact
with the cams by means of spiral springs e" which serve to move the shafts wⓇ in
one direction, the cams moving them in the opposite direction and in this manner
the cams and springs produce at the exact times required the proper oscillating
movements of the fingers so and b as the hubs us are inoved along on the shafts wo
as above described.
As regards the fifth movement the oscillation of the separating arms the shaft 7
carries a bevel wheel which gears into a similar wheel on the lower end of a
vertical shaft 98. carrying at its upper end a bevel wheel which gears into a
wheels on a horizontal shaft supported in bearings on the uprights b of the
framework.
This shaft carries two scroll cams k the groove in each of which is provided
with two straight portions and two double inclines on opposite sides of the cam
(Figures 3 and 28).
Into these grooves fit the lower ends of two arms extending down from
short shafts forming continuations of the shafts p. and thus as the cains k³. are
rotated the desired rocking movements are alternately imparted to the separating
arins the double inclines . of one cam being opposite to the centres of the
spaces between those of the other cam in order that the movements of the two rock
shafts and their separating arms may alternate as required.
As regards the sixth movement the end wise reciprocating motion of the heddles
it will be seen that the faces of the cains are provided with projections or
tappets n (Figure 1 and 28) which as the cams revolve are brought into contact
with the bent lower ends of two rods " which pass through guides q' and are
pivoted at their upper ends to studs projecting from two vertical rods which are
thus lifted each time one of the projections ns. striking and passing up out of
contact with the end of the rod 2 The vertical rods are each pivotted at their
upper and lower ends to rockers (Figures 13 and 28) these rockers being
pivoted upon the opposite sides of supporting pieces to attached to the framework.
The inner flat faces of these rockers & fit squarely against the toe pieces we secured
to the ends of the sliding roda d and k and thus as the rockers are oscillated
through the connections described the rods d and k are moved in the direction of
their length to operate the heddles in one direction the spiral springs a returning
them to their original positions on the reverse movement of the rockers 88.
-
The rods d and I are flattened on their sides where they slide in the framework
and the recesses or grooves in which they slide are open at the top te adinit of
their ready removal the rods being confined in place at one end by a bar or
button which may be turned to one side when the rods are to be taken out.
Soon after the hooked needle Q has drawn a warp-thread one of the eyes of a
heddle and through the reed a revolving finger or arm c' (Figures 3, 4 and 28.)
strikes the thread and draws it out of the hook 62 of the needle and casts it over to
one side out of the way thus preventing the needle from carrying the thread back
again on its return stroke as it might otherwise do.
This revolving finger is attached to the end of a horizontal shaft (Figures 5
and 28) having its bearings in the slide F and carrying a bevel wheel gearing
into a similar wheel f" on the top of a vertical shaft g a bevel wheel on the lower
end of which gears into a wheel p on the shaft E¹ and in this manner the
finger co is caused to perform its work of drawing the thread out of the needle at
the proper time which is when the said point has been drawn back out of the path
of the finger so that the latter will clear it as it rotates.

page_text: Each of the rock-shafts po is made renovable to enable it to be easily taken out
of the Machine one end fitting into a spring socket while the other end slides
within a socket 97 at the end of a short rock-shalt h (Figure 19) having its
bearing in the framework and forming a longitudinal extension of the shaft po a
sinall projection in the socket g' entering the groove in the scroll cam po whereby
the two shafts are caused to move together.
The above described machine is constructed to operate upon two heddles only
but a machine may be made for operating upon three or more heddles in which
case a series of automatic devices the same as above described will be required for
each heddle.
The gearing by which the driving shaft is connected with the foed screw will
also require to be changed as the number of strokes of the needle Q between each
movement of the feed screw G and slide F must correspond to the number of
heddles suspended within and operated upon by the machine and the relative sizes
of the wheels must be such that for two heddles two revolutions of the driving
shaft will cause the segment q¹ to engage with the gear o¹ on the end of the feed
screw for three heddles three revolutions of the driving shaft and so on the
segment q' having the exact number of teeth necessary to turn the feed screw and
advance the slide F the proper distance to insure the accurate operation of the
needle Q.
In operating the machine it is necessary that the first two or three eyes of the
heddles at each end should have two warp threads passed through them instead of
one in order to form the selvage in the usual manner. This is effected by operating
the clutch by the hand lever at the required time so that the bevel wheel h
will not be rotated by the driving shaft thus throwing out of action the various
devices for operating upon the heddles and producing the feed of the carriage until
the needle has drawn two threads instead of one through the eye when the
mechanisin is again brought into action to bring the next eye into position after
which it is again thrown out to cause the second eye to receive two threads and so
on until the selvage has been drawn on that side when the entire mechanism is
thrown into action and allowed to continue in action until the needle Q has nearly
reached the opposite end of the heddles when the operation of alternately dis-
connecting and connecting the mechanisin controlled by the clutch is repeated to
cause the selvage to be drawn at that end of the heddles as required.
Having now explained the construction of the different parts composing the
machine and the operation of different features I will now describe in brief terins
the operation of the principal operating parts in relation to each other.
Let it be supposed that the needle has reached the limit of its rearward
movement that the screw G has fed the slide F to the desired extent and that the
needle is about to commence its forward movement. The warp thread about to be
seized by the needle is with others between the jaws of the nippers A¹ (which
however have not yet seized the thread) and against the bearing edge de the point
of the hook C' of the disk B₁ is at its greatest distance from the thread which it
has to subsequently seize the separating arm q' apportaining to the heddle D is in
the act of pushing the eye 62 of the said heddle against the finger 8' which is
stationary and the separating arm q* appertaining to the heddle E is quiescent in
its central position where it keeps the eyes of the said heddle E away from the
course of the needle.
We will now suppose that the needle is in the act of moving forward and has
passed through the read. Before its point reaches the eye 62 of the heddle D the
separating arm of that heddle has completed its duty and is stationary in its central
position while it holds the eye 62 of the heddlo against the finger & so that it will
be in a proper position to receive the point of the needle. In the meantime the
separating arm and fingers 8 and 67 appertaining to the other heddle E are in the
act of perforining the duty of separating the eye last threaded of that heddle from
the other eyes so as to clear the way for the needle and prevent it from passing
through any eye of the said heddle.
:

page_text: The needle having passed through the reed through the eye 62 of the heddle D and
between the threaded eye and next eye of the heddle E is approaching the limit of
its forward moment. Before it reaches this point however the nippers A¹ have
seized a number of threads including that destined to be caught by the hook of the
needle has drawn the threads upward as well as laterally against the fingers
and ka so that the first thread of the series will be pressed against the periphery of
the oscillating disk B' and in a position to be seized by the hook C of the said
disk.
When the needle has reached or very nearly reached the limit of its forward
movement (Figure 14) the disk B suddenly turns to such an extent that its
pointed hook seizes the first warp thread and drags it into the curved slot 58 of the
disk and against the needle which has turned on its axis before reaching this point.
The needle no sooner reaches the limit of its forward movement than it commences
to return in doing which its hook catches the warp thread and the disk turns back
so that its hook loses control of the thread which is now drawn away by the
receding needles from betweer the rod f³ and the felt of the bar g³ and away from
the other warp throads through the heddle E without passing through one of its
eyes through the eye 62 of the heddle D and through the reed after which the
thread is removed from the needle by the hook c³.
While the needle is in the act of thus receding an eye of the heddle E is being
prepared by the devices and movements above described for receiving the needle
during its next forward movement and the eyes of the heddle D are being so
arranged in the manner and by the appliances described that during the next
forward movement of the needle it will pass between eyes and not through an eye
of the said heddle.
When the needle has arrived or nearly arrived at the limit of its rearward
movement the carriage is fed to the desired extent and a repetition of the above
described operations takes place.
Referring to Figures 37 to 44 inclusive which illustrate modified nechanisın for
operating on the heddle threads and eyes it will be observed that the shafts p
previously described as passing through the heddles and the separating arins q
which operated on the eyes of the heddle threads as set forth in the foregoing
description are dispensed with as also is the frame composed of the parallel bars
lo mo and n (Figure 25.)
In Figure 37 Ws is part of a bar which takes the place of the bar W in the
machine above described and which is carried by the intermittently traversed
slide F and its reciprocating needle Q.
On this bar Ws are secured two stands W, W the tops of which are above the
eyes of the heddle cords as shown in Figures 39 and 44 where the relation of the
stands to the heddle appears.
It should be remarked here that in the several views 37 to 44 inclusive
mechanism for operating on one heddle only is shown and this will suffice as
mechanisin for operating on the other heddle or heddles is precisely the same as
that about to be described.
Adjoining the stands W4 and having their upper bearings therein are the vertical
shafts the former carrying a hook x2 and the latter a hook ³ these two hooka
act on the threads of one heddle one on one side and the other on the opposite side
of the same as explained hereafter.
The lower ends of the two shafts xx¹ are attached to but can oscillate in a
cross-bar shown by dotted lines in Figure 37 and an intermittent vertical
reciprocating notion is imparted to this cross-bar shafts and hooks from the
shaft W in the present instance by an eccentric W10, the rod of which is connected
to a lever having its fulcruin on the bar W and connected to the cross-bar
An intermittent oscillating movement (not simultaneous) is imparted to the hooks
xx³from a shaft W on which is a cam W7 for operating a bell crank lever
pivoted to an attachment on the bar Ws one arm of the lever being connected by
a rod to an arın x7 on the shaft x¹ the arm being confined vertically and the

page_text: shaft being arranged to slide in but oscillate with the arm. A Cam Ws serves to
impart an oscillating movement to the shaft x by mechanisin similar to that last:
described.
Two levers N and No are pivotted to the bar W the lower arm '' having
pins adapted to grooves in the Cam wheel W the pin of one lever in one groove in
one side of the cam-wheel and the pin of the other lever on the opposite side of
the wheel.
The lever N has two upper arms 2 and z' the former terminating at the top in
a finger j and the arm having guides for the rod j the lower end of the latter
having an arın with which a pin on the cam wheel W comes in contact at
intervals as the shaft Ws revolves.
At the upper end of the rod j' is a jaw having an elongated eye for a purpose
explained hereafter. The lever N³ has a single arm terminating in a jaw j'
which has also an elongated eye.
It will be well here to refer to the following movements of the above described
parts.
First there is the intermittent vertical and simultaneous reciprocating movement
of the two hooks and Second the intermittent oscillation of the said hooks
at different intervals, Third the intermittent vibration of the finger Fourth
the intermittent oscillation of the jaw always in the same plane Fifth the
intermittent vibration of the jaw simultaneously with the vibration of the
finger and Sixth the sudden lateral oscillation of the jaw j due to the striking of
the arm at the lower end of the rod or shaft j by the pin on the cam wheel W'.
It should be understood that there is a spring which moves the jaw j inwards aftor
it has been moved outwards by and is free from the control of the pin ja on the
cam wheel.
The timing of the movements of the several parts and the result attained thereby
can be best explained by reference to Figures 38 to 44 inclusive.
In Figure 38 the two hooks and as have been elevated and the points of both
hooks are opposite the space between the cords all and a of the hoddle D. When
the hooks have reached this position a movement in the direction of the arrow,
Figure 38 is imparted to the slide and reciprocating needle and consequently to
the entire mechanism above described the points of the hooks consequently entering
the space between the said cords. As the hooks descend the first cord 12 will be
soparated from the next cord a" and by the time the hooks have reached the limit
of their downward moveinent the hook 3 will have released the cord a while
the hook 2 retains the cord " as shown in Figure 39 and holds the said cord all
back as well as all the succeeding cords.
After the hooks have reached the position Figure 39 the jaw j is moved back
to the position shown in Figure 40 and the jaw is moved outwards.
At this point takes place the sudden endwise reciprocating novement of the
boddlo referred to in the general description of the machine and this shakes the
cord a free from the cord a should there be a disposition of one cord to adhere
to the other. The cord a¹s and its eye 63 are now in such a condition that when
the jaw resumes its former position (Figure 41) and the jaw is released so as
to spring back the eye 63 will be so held by the jaws that the needle Q will pass
through the said oye.
It should be here remarked that the elongated openings in the jaws prevent the
eye of the heddle cord from being closed.
The needle Q having passed through the eye of the heddle cord in the act of
retreating after seizing a warp thread the hooks will assume the position shown in
Figure 42. After the needlo has drawn the warp throad through the eye of the
beddlo cord and its point is clear of the jaws the jaw is moved outwards as
shown in Figure 43 and simultaneously the finger j is moved in the same direction
and pulls the eye away from the path of the needle the jaw 7 yiolding and
permitting this movement of the eye of the heddle cord.
Immediately after this the several parts assume the position shown in Figure 44

page_text: and a repetition of the above described movements takes place, the eye 63 of the
next heddle cord being operated upon.
It should be understood however that this does not take place until after the
needle has passed through and retreated from an eye of a cord of an adjoining
beddle which is not shown in the drawing.
The improvement in the heddle holder is shown in Figure 45 D being part of
the heddle and the upper bare of the same being furnished with two eyes ƒ one
only being shown in the Drawing. A threaded shaft d has its bearings in the
fraine of the machine and is adapted to two nuts c each of which is connected to
an eye by an adjustable screw i.
The lower bar of the heddle is connected by precisely similar devices to nuts c
on the lower screw shaft.
These screw shafts are geared together in the manner shown or in any other
suitable manner so that the nuts of the upper and lower screw shafts can be
traversed simultaneously and the heddle thereby adjusted for a nice adjustment of
the heddles in respect to the warp threads is essential.
I do not wish to limit myself to the mechanisin described through the medium
of which the essential parts are actuated from the driving shaft as this mechanism
can be varied without departing from the main features of the Invention.
Having now described and particularly ascertained the nature of the said Inven-
tion and the manner in which the same is or may be used or carried into effect I
would observe in conclusion that what I consider to be novel and original and
therefore claim as the Invention secured to me by the hereinbefore in part recited
