Machinery or Apparatus therefor.
We, WILLIAM TAYLOR, of 8 Mill Street, Kidderminster, Weaver, and WILLIAM
YOUNGJOHNS, of Sutton Road, Blackbrook, Kidderminster, Power-loom Tuner, both
in the County of Worcester, do hereby declare the nature of this invention to be as
follows:-
"
Our invention relates to the manufacture of carpets and to machinery or apparatus
therefor, and is chiefly designed to provide for making "Turkey carpets by
machinery.
Our said invention comprises an improved method of weaving carpets by machinery,
which method consists in first laying the worsted upon the ground chain and cutting
a piece of the desired length from the said worsted, then pushing the ends of the said
piece between the threads of the said chain so as to enclose two of the said threads,
bringing the said ends together beneath the chain, and then drawing them up through
the said chain between the said two threads. In this manner the pieces of worsted
are securely attached to the chain like those in a Turkey carpet. The ground weft is
woven in the ordinary manner after a row of pieces of worsted has been woven or
secured to the chain as above described.
An important feature of our said invention is the employment of feed-mechanism
which is so constructed that any desired number of different colored worsteds can be
fed thereby, as required, into position to be operated upon by the cutting and weaving
mechanism. This feed-mechanism comprises a slide provided with a series of
apertures or passages through which the different colored worsteds are conducted from
reels or bobbins suitably supported upon the loom. Feed-rolls are arranged in
combination with each of the said apertures or passages, and the said slide is provided
with means whereby it may be adjusted to bring either of the said feed-rolls into
position to be operated by a feed-wheel or cam.
This feed-wheel or cam is so constructed that it will, in each rotation, feed the
required quantity of worsted through the feed-slide.

page_text: In combination with this feed-mechanism, we employ a device for indicating to the
attendant which color of worsted is being fed and woven.
Another feature of our said invention is the provision of a knife, cutter or pair of
shears, arranged to operate after the worsted has been fed through the aforesaid slide,
to cut off a piece of the said worsted of the required length.
Another feature of our said invention is the employment of a forked arm, and
means for operating the same to push the ends of the pieces of worsted through the
ground chain, in combination with a pair of nippers or tweezers, and means for
operating the same, to seize the ends of the pieces of worsted and draw them up
between the threads of the said chain in the manner above specified.
Our said invention, moreover, comprises the employment of a box or frame in
which the various devices above described are arranged, and which is provided with
means for intermittently moving it across the loom in front of the lathe, to permit the
mechanism to successively insert the pieces of worsted, and with a counterweight or
other suitable means for effecting the rapid return movement of the said box or
frame, when a row of pieces of worsted has been completed, to bring the mechanism
into position to commence a fresh row thereof.
Our invention is applicable to various kinds of power looms, and is conveniently and
advantageously carried into practice as hereinafter described, that is to say ;-Two
rails are suitably supported in front of the lathe and parallel thereto, and are provided
with means for raising them when necessary to permit the operation of the lathe.
A carriage provided with rollers or wheels is placed upon these rails, and to this
carriage is attached the box or frame in which the aforesaid devices are arranged.
A driving shaft is mounted in suitable bearings in the said frame, and has fixed
thereon a pulley whereby motion may be transmitted thereto from the driving shaft
of the loom. This shaft is connected by suitable gearing with another shaft mounted
in bearings in the said frame and having fixed thereon the feed wheel or cam.
feed shaft is connected by bevel pinions with another shaft for operating what I will,
for convenience of description, herein term the knotting mechanism.
This
The feed slide is arranged beneath the feed shaft and is connected, at one end, to a
coiled spring arranged within a box or casing, and, at its other end, to a strap or
band arranged to be wound upon a pulley fixed on a shaft mounted in the frame at
right angles to the feed-shaft. The feed-slide is divided into as many compartments
as there are colors in the carpet to be made, and a pair of feed-rolls is arranged in
combination with each of the said compartments. Each worsted is conducted from
the bobbin upon which it is wound through an aperture in one or other of the said
compartments and between the corresponding feed-rolls. The winder-shaft is
connected by suitable gearing with a crank-handle. By turning this handle in one
direction, the aforesaid band will be wound upon its pulley and the feed slide thus
moved in a direction parallel to the axis of the feed-shaft, and the aforesaid spring
will be uncoiled. When the said handle is turned in the reverse direction, the said
spring will react and draw back the feed-slide. The said feed slide can thus be
adjusted to bring either of its pairs of rolls into position to be operated by the feed
wheel or cam according to the colour of worsted to be woven. The said crank-handle
is preferably provided with a stud or projection which will enter one or other of a
series of holes or indentations in a disc or segment, when either of the compartments
of the feed-wheel is in operative position. A dial and pointer are, moreover, arranged
in combination with the feed slide, to indicate to the attendant which color of worsted
is being woven. He can therefore readily control the feed-slide according to the
pattern to be produced in the carpet. The end of the feed-shaft nearest the feed-
wheel or cam is preferably held down by a spring so that the said wheel or cam will
exert a yielding pressure upon the feed rolls.
The feed-mechanism is so arranged that it will feed the worsted into the proper
position to be operated upon by the knotting mechanism; and a knife, cutter or pair
of shears is arranged in combination with the feed-mechanism for cutting the worsted
as soon as the feed stops. The feed wheel or cam is constructed in such a manner
that it will in each operation, feed a given length of one or other of the different

page_text: coloured worsteds through the said feed slide. The knife or cutter is operated by
means of a cam upon the shaft of the knotting mechanism, or in any other suitable
manner.
The said knotting mechanism is constructed as follows, viz :-An excentric is fixed
upon the said shaft and is coupled by means of an excentric rod to an arm or segment
fitted to turn upon a pin or stud fixed in the frame. This arm or segment is, moreover,
coupled by means of a connecting rod or link with the short arm of a forked lever for
pushing the ends of the pieces of worsted through the ground chain. The two parts
of the nippers or tweezers for seizing the ends of the pieces of worsted and drawing
them up through the said chain are pivotted to the said arm or segment and are
curved so that they move in the are of a circle. They are provided with springs
which tend to keep them closed, and with studs which, when the said arm or segment
is turned in one direction, strike a projection upon a pivotted lever or plate and are
thereby moved apart, thus opening the nippers or tweezers. As soon as the said studs
pass the said projection, the aforesaid springs immediately close the said nippers or
tweezers and cause them to seize the worsted. The said pivotted lever or plate is held
down by a spring so that, in the return movement of the said arm or segment, it
will be raised by the said studs, so that the latter can pass under it, and the nippers or
tweezers will remain closed.
A lever is pivotted to the aforesaid frame and has a pawl pivotted to its upper end
and adapted to engage with a rack fixed upon one of the aforesaid rails. This lever
is operated by a stud or projection on one of the toothed wheels of the gearing, to
move the said frame intermittently across the loom. A retaining pawl is, moreover,
pivotted to the said frame to prevent backward movement thereof. Suitable means
are provided for throwing these pawls out of engagement with the rack when a row of
pieces of worsted has been completed; and a counterweight is provided for effecting
the return motion of the said frame.
In some instances, I combine, with a single loom, two or more sets of the above
described devices. This arrangement is especially advantageous for weaving carpets
of great width, as it enables several attendants to work simultaneously at the same
carpet.

We, WILLIAM TAYLOR, of 8 Mill Street, Kidderminster, Weaver, and WILLIAM
YOUNGJOHNS, of Sutton Road, Blackbrook, Kidderminster, Power-loom Tuner, both in
the County of Worcester, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
Our invention relates to the manufacture of carpets and to machinery or apparatus
therefor, and is chiefly designed to provide for making Turkey carpets by machinery.
Our said invention comprises an improved method of weaving carpets by machinery,
consisting in first laying the worsted upon the ground chain and cutting a piece of the
desired length from the said worsted, then pushing the ends of the said piece through
the said chain so as to enclose two of the threads thereof, bringing the said ends
together beneath the chain, and then drawing them up through the said chain between
the said two threads. In this manner the pieces of worsted are securely attached to
the chain like those in a Turkey carpet. The ground weft is woven in the ordinary
manner after each row of pieces of worsted has been woven or secured to the chain
as above described.
In our improved machinery, we employ feed-mechanism which is so constructed.
that any desired number of different colored worsteds can be fed thereby, as required,
into position to be operated upon by the cutting and weaving mechanism. This feed-
mechanism comprises a slide which is mounted in a box, frame or carriage arranged
to move to and fro upon rails at the front of the loom, and is provided with a series
of apertures or passages through which the different colored worsteds are conducted
from reels or bobbins suitably supported upon the loom or upon the said box, frame
or carriage. Feed-rolls are arranged in combination with each of the said apertures
or passages, and the said slide is provided with means whereby it may be adjusted to
bring either of the said feed-rolls into position to be operated by a feed-wheel or cam.
This feed-wheel or cam is so constructed that it will, in each rotation, feed the
required quantity of worsted through the feed-slide.
In combination with this feed mechanism, we employ a device for indicating to the
attendant which color of worsted is being fed and woven, and for enabling him to
adjust the feed-slide according to the color of worsted which it is desired shall be fed
and woven.
We also provide a knife, cutter or pair of shears, arranged to operate, after the
worsted has been fed through the aforesaid slide, to cut off a piece of the said worsted
of the required length.

Figure 3 is a side elevation of part of the said mechanism.
Figures, 4, 5 and 6 are different views hereinafter described and drawn to an
enlarged scale, illustrating the improved method of weaving by the aid of the said
mechanism.
a, a are two rails which are suitably supported in front of the lathe of a power
loom (not shown in the drawings) parallel to the said lathe, and which are provided
with means (not shown in the drawings) for raising them when necessary to permit
the operation of the lathe, and again lowering them. is a carriage provided with
rollers or wheels a¹ and placed upon the said rails. c is a box or frame suspended
from this carriage by means of rods c¹³,
A driving shaft d is mounted in suitable bearings in the frame c and has fixed
thereon a pulley d' whereby motion may be transmitted thereto from the driving
shaft of the loom by means of a band or rope d². This shaft d is connected, by the
gear-wheels d³, d, with another shaft d³ also mounted in bearings in the said frame c,
and having fixed thereon the feed wheel or cam e. The feed-shaft d³ is connected,
by bevel pinions d³, d', with another shaft f for operating what we will, for
convenience of description, herein term the knotting mechanism.
el is the feed-slide, which is arranged beneath the feed-shaft d³, and is connected,
at one end, to a spring e2 and, at its other end, to a strap or band e arranged to be
wound upon a drum or pulley et fixed on a shaft e, which is mounted in the frame c
at right angles to the feed-shaft d, and which we will hereinafter term the winder-
shaft. The said feed-slide is divided into as many compartments as there are colours
in the carpet to be made, and a pair of feed-rolls e' is arranged in combination with
each of the said compartments. These feed-rolls are held down by springs e* and will
readily adjust themselves to any inequalities in the worsted. The different coloured
worsteds g, g are wound upon different bobbins g², g₁ placed upon pins b² fixed in the
carriage b. Each worsted is conducted from the bobbin upon which it is wound
through an aperture e in one or other of the said compartiments and between the
corresponding feed-rolls e. The winder-shaft e, for moving the slide to bring the
coloured worsteds into the proper position to be woven, is connected, by the bevel
wheels e, e¹¹, and gear-wheels e¹³, e¹³, with a crank-handle e. By turning this
handle in one direction, the aforesaid band e3 will be wound upon its drum or
pulley e* and the feed-slide e¹ thus moved in a direction parallel to the axis of the
feed-shaft do, and the spring will be extended. When the said handle e is turned
in the reverse direction, the said spring e² will react and draw back the feed-slide e'.
The feed-slide can thus be adjusted to bring either of its pairs of rolls e into position
to be operated by the feed wheel or cam e according to the colour of the worsted to
be woven. The said crank-handle e³ is preferably provided with a stud or projection /
which will enter one or other of a series of holes or indentations in a disc or
segment 2 attached to the frame c, when either of the compartments of the feed-
slide e' is in operative position. The said disc or segment is divided into parts
corresponding in number with the bobbins on the machine, and the various parts are
sometimes coloured so as to indicate to the attendant what colour of worsted is being

page_text: woven. A pattern or guide and pointer are, moreover, in some instances, arranged in
combination with the feed-slide, to indicate to the attendant which color of worsted
must be woven and how the colours must succeed each other in order to produce the
desired pattern in the carpet.
The attendant can, by these means, readily control the feed-slide according to the
pattern to be produced in the carpet. The end of the feed-shaft d³ nearest the feed
wheel or came is preferably held down by a spring ds, so that the said wheel or cam
will exert a yielding pressure upon the feed-rolls e
The feed-mechanism is so arranged that it will feed the worsted into the proper
position to be operated upon by the knotting mechanism; and a knife or cutter is
arranged in combination with the feed-mechanism, for cutting the worsted as soon as
the feed movement ceases. The knife or cutter is pivotted at to the frame e and
is operated by means of a cam i¹ fixed upon the shaft f of the knotting mechanism,
and a spring connected, at one end, to the said knife and, at the other end, to the
frame c or it may be operated in any other suitable manner. Any other suitable
cutter, or a pair of shears may, moreover, be substituted for the said knife. The
cutting edge of the said knife passes in contact with the surface of the slide e¹ so that
it will sever a piece from the worsted projecting from the said slide. The feed wheel
or came is provided upon its periphery with a piece of india-rubber, leather or
other suitable material which, in each rotation of the said wheel, will engage with
the fluted periphery of one or other of the feed-rolls e and rotate the said rolls.
The length of this piece e¹ will determine the length of the pieces of worsted fed
through the slide e¹, and cut or severed in each operation of the feed and cutting
mechanism.

The said knotting mechanism is constructed as follows, viz:-An eccentric j is fixed
upon the shaft and is coupled, by means of an eccentric rod, to an arm or segment
fitted to turn upon pins or studs 3 fixed in the frame c. This arm or segment 2 is,
moreover, coupled, by means of a connecting rod or link k, with the short arm of a
lever k¹, which is pivotted at 2 to the frame c and the long arm of which is forked to
adapt it for pushing the ends of the pieces of worsted through the ground chain / so
as to enclose two threads thereof. m, m are the nippers or tweezers for seizing the
ends of the pieces of worsted, after they have been pushed through the chain by the
lever k¹, and drawing them up through the said chain; the two parts of these nippers
are pivotted at m* to the said arm or segment and are curved to form of an arc of a
circle. They are provided with springs m', which tend to keep them closed, and with
studs m² which, when the said arm or segment is turned in the direction indicated
by the arrow in Figure 2, will strike a projection m³ upon a lever or plate m¹ pivotted
at m³ to a bracket me secured to the frame c, and the two jaws of the nippers will thus
be moved apart or opened. As soon, however, as the said studs m² pass the said
projection, that is to say, when they arrive in the position shewn in Figure 3, the
springs m' will immediately close the said nippers or tweezers and cause them to seize
the ends of the piece of worsted which have been pushed through the chain by the
lever k¹. The said pivoted lever or plate m is so arranged that, in the return
movement of the said arm or segment j, it will be raised by the said studs m², so that
the latter can pass under it, and the nippers or tweezers m will remain closed
until the said segment is again moved in the direction indicated by the arrow in
Figure 2.
A lever n is pivotied at n¹ to the box or frame c, and has a pawl n² pivotted to its
upper end and adapted to engage with a rack n³ fixed upon one of the aforesaid
rails a.
This lever n is operated by a cam-groove n in the toothed wheel d¹ to move
the said frame intermittently across the loom. A retaining pawl n³ is, moreover,
pivotted to the said frame to prevent backward movement thereof.
Suitable means are provided for throwing these pawls out of engagement with the
rack when a row of pieces of worsted has been completed. For instance, a lever n
is pivotted at n to the carriage b and is provided with two rods n³, which extend
downward on the inner sides of the pawls n², n°. This lever is coupled to a rod or
bar n³ whereby it may be operated to disengage the pawls from, or permit their

page_text: engagement with the said rack n³. A counterweight or a spring (not shewn in the
drawings) is provided for effecting the return motion of the frame c, when the said
pawls are thus disengaged from the rack. In some instances, we provide means for
automatically effecting the disengagement of the said pawls from the rack.
We have found in practice that, as the worsted emerges from the apertures or
tubes e, the end thereof is liable to drop so that it either catches one of the threads
of the chain land is thus caused to double or fold, or else passes between the threads of
the chain, so that the piece cut from the worsted will not be in the proper position to
be acted upon by the knotting mechanism. To obviate this defect, we provide what
we term a "conveyor" consisting of a bar o fitted to slide in a guide-way in the
frame c and formed with a notch or groove to receive the worsted. This bar is
coupled to a lever o* pivotted at o' to a bracket o² secured to the frame c, and is
operated, through the medium of a connecting rod o³ and lever o, by a cam o' fixed
on the shaft The said lever o is held against this cam by a spring o. This
conveyor receives the worsted from the slide e¹ and lays it properly upon the chain as
hereinafter described.
We have also found that it is necessary to keep the threads of the chain at regular
distances apart, otherwise the forked lever k¹ is liable to push the ends of the pieces
of worsted between the wrong threads of the chain, thus producing a fault in the
carpet. To keep the said threads at regular distances apart, we provide a comb
fitted in slots p¹ in brackets p² secured to any suitable part of the frame of the loom
springs pare attached to the said brackets p² and tend to keep the teeth of the comb
between the threads of the chain. We prefer, moreover, to arrange the bars of the
lathe at equal distances apart and to make the spaces between them of just sufficient
width to allow the threads of the chain to pass easily between the said bars.
;
q is a lever which is pivotted at q* and is connected, by means of another lever g²
pivotted at q³, with a friction-clutch q', so that, by raising or depressing the said lever q,
the shaft d can be put into or out of gear with the driving pulley d¹.
The operation of our improved mechanism is as follows, viz:-Assuming the parts to
be in the positions indicated in Figures 1 and 2 and the shaft & connected, by the
clutch q, with the driving pulley d₁, motion is transmitted, by means of the
wheels d³, d, to the feed shaft d, and, through this shaft and the bevel wheels d³, d²,
gear-
to the shaft f. The feed-wheel e operates the feed-rolls e beneath it and thus causes
a certain length of worsted (determined by the length of the piece e" of india-rubber
on the said wheel) to be ejected from the corresponding aperture or tube 8 of the
slide e¹.
As the worsted issues from the tube in the feed-slide, it is supported by the
"conveyor "o, and, as the cam o rotates, the spring of draws back the said conveyor
and permits the worsted to lie evenly upon the chain; a piece is then cut or severed
from the worsted by the knife i.
The forked end of the lever k¹ is now moved downwards and caused to push the
ends of the said piece of worsted down through the chain so as to enclose or encircle
two of the threads of the chain as indicated by Figures 4 and 5, and the said lever
continues its descent until it assumes the position shown in Figures 3 and 5.
Figure 4 shows, in plan, the piece of worsted resting upon the chain, and the
lever in position to push the ends of the said piece through the chain.
Figure 5 shows, in side elevation, the piece of worsted after its ends have been
pushed through the chain by the said lever.
In the rotation of the shaft and eccentric j, the segment is partially rotated in
the direction indicated by the arrow in Figure 2, and the free ends of the nippers or
tweezers m are caused to pass between the threads of the chain and are then opened
by the projection m3; as soon as the studs m³ have passed the projection m³, the
springs m¹ close the said nippers and thus cause them to grip the ends of the piece of
worsted, as shown in Figure 6, which is a side elevation. As the eccentric j continues
to rotate, it draws back the segment and thus causes the nippers m to draw the ends
of the piece of worsted up between the threads of the chain as shown in Figure 6,
thus completing the operation. The cam-groove n* then operates the lever n and

page_text: causes the pawl n² to engage with the teeth of the rack n³ and move the carriage b
and the mechanism supported thereby into position for the next operation.
In some instances, we combine with a single loom two or more sets of the above
described mechanism. This arrangement is especially advantageous for weaving
carpets of great width, as it enables several operators to work simultaneously at the
same carpet.
"'
In some instances we provide a bell and form or fix a hammer or clapper l on
the knife i, so that, after each length or piece has been cut or severed from the
worsted, the said bell will be sounded and the operator will then know that he may, if
necessary, adjust the slide e to bring worsted of another colour into position to be fed
through the said slide.
.
