Improvements in Looms for Weaving.
1, JOHN POYSER, of Peck's Hill, Sherwood Road, Mansfield, in the County of
Nottingham, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to looms for weaving and chiefly to high speed looms
of the kind described in the Specification of former Letters Patent granted to me
No. 15431 of 1893.
According to my present invention I provide a single picker-lever, pivotted in
the base of the machine, and having a roller or projection engaging in the groove
of a cam upon the driving shaft so that as the shaft revolves the lever vibrates
upon its centres. To the upper or free end of the picker-lever are pivotted two
radial pickers, each of which is provided at its free end with a roller or projection
adapted to engage in a cam-slot or groove cut in or attached to the frame of the
loom, and also with a tooth projecting upwards between the sides of the shuttle-
race and adapted to engage in a recess in the shuttle when the picker is raised by
the action of the cam-slot upon its roller or projection, and to be clear of the warp
threads when lowered by the same, and the cam-slot is so arrauged that the teeth
of the pickers engage alternately with the shuttle, each picker being raised before
the other is lowered so that the shuttle is passed backwards and forwards through
the shed in a positive manner when the picker-lever is vibrated by its actuating
cam.
The healds or heddles are advantageously formed by rivetting together two
strips of sheet metal by means of two rivets in the centre of the strips, a space
being left between the rivets for the warps, the rivets and the sides of the strips
thus forming an eye, this construction enabling me to arrange the needles closer
together than heretofore in the heald or heddle frames, and at the same time to
reduce the friction between the needles and the warp threads, the needles
having parallel sides, instead of being enlarged at the eye as in needles of ordinary
construction.
The warp take-up rollers instead of presenting metal surfaces to each other as
heretofore are arranged as follows, that is to say, one of them is faced or covered
with powdered emery or any similar substance so as to form a rough surface, and
the other with india-rubber, leather or other soft material, the two being held
together by means of a spring and provided with any suitable device for throwing
them out of contact when required. Instead of using the roughened roller herein-
before described I may use a fluted roller.
In order to permit of regulating the feed I advantageously employ the following
arrangement in lieu of that described in the former Specification, that is to say,
the clutch lever instead of being directly operated by a cam is connected by a
link to an adjustable nut in a slotted lever worked by a cam, the amount of move-
ment of the rollers and the consequent feed of the warp being varied by adjusting
the nut in the slot of the lever.
In order to take up or compensate for the slack of the warps at the closing of
the shed, a lever or frame is employed, carrying at each end a warp guide-roller,
and pivotted at its centre upon a fixed spindle, the warps being passed from the
let-off rollers, under one guide-roller and over the other to the healds or heddles.
Or a single compensating roller may be arranged in a frame pivotted at one end.

page_text: In either case the compensator is acted upon by a spring or springs so as to bear
upon the warps and take up the slack, at the same time maintaining an even tension
of the threads.
The guide-rollers of the compensator are advantageously formed of smooth
spindles pivotted loosely in the compensator frame, and having thin discs of metal
threaded loosely upon them, the whole of the discs being kept within the required
width by means of collars at each end. The warps are passed over the rollers
with the discs between them, and the warps are thus guided and prevented from
rubbing together.
The let-off for the warps comprises a pair of rollers arranged similarly to those
of the take-up, the said rollers being carried in a frame fixed to the bed of the
loom which preferably carries also the spindle of the compensator hereinbefore
described. The warps are passed from the warp-beam, or preferably from separate
cops or bobbins beneath the table or bed of the loon, through a suitable guide,
and between the let-off rollers to the compensator. One let-off roller is preferably
of large diameter and provided with a brake of any convenient construction,
pressed upon the roller by means of a spring or springs and acted upon by means
of a cam or projections upon the compensator so that when the shed is closed and
the compensator is pulled backwards by its spring, the brake holds the roller
firmly, whereby the rollers are prevented from feeding forward; when, however,
the shed is opened and the compensator is pulled forward against its spring, the
cams or projections hold the brake off its roller and allow both rollers to revolve,
and the warps being pulled forward by the take-up rollers, the backward movement
of the compensator permits the brake to return to the roller.
The let-off rollers are provided with any suitable devices for adjusting their grip
upon the warps, and for throwing them apart when required, and are advantageously
actuated by means of a friction pawl or clutch the lever of which is connected by
a rod to the clutch-lever of the take-up rollers so that the amount of let-off
corresponds with that of the take-up.
The let-off rollers are provided with guides at the front and back so as to ensure
the warps passing through in an even manner.
The shuttle of the loom is provided with a projecting finger for laying the weft
thread and with a take-up lever which may be either a spring-lever as hitherto, or
actuated positively by means of a cam-slot or groove in or upon the shuttle-race,
the said cam-slot or groove engaging with a projection or projections upon the
take-up lever in such a manner as to maintain au even tension of the weft thread
at all parts of the shuttle's stroke, without the employment of a spring.
I also combine with the shuttle spool a friction brake which is mounted upon a
brake lever and kept against the shuttle spool by means of a spring so as to
prevent its revolving when the take-up lever is in its backward position and taking
up the slack; when, however, the take-up lever is pulled by the weft into its
forward position, that is to say, when the shuttle is at or near the end of its stroke,
a cam or projection upon the take-up lever bears upon the brake lever so as to
remove the brake from the spool, and allow the required amount of weft to be
paid out.
Instead of adapting the shuttle to receive a spool, I may arrange it to receive
a cop or ball.
In conjunction with the hereinbefore mentioned spring take-up lever I provide
an arrangement whereby the loom is stopped on the breaking of the weft thread.
This arrangement consists of a sliding bolt upon the shuttle, connected in any
convenient manner with the spring take-up lever, so that when the take-up lever is
in its forward position, corresponding to the end of the shuttle's stroke, the sliding
bolt is drawu in flush with the shuttle; when, however, the take-up lever is in its
backward position, corresponding to the middle of the shuttle's stroke, the bolt
projects beyond the shuttle; if, therefore, the weft thread breaks, the take-up
lever is thrown by its spring into the backward position, and the bolt is thrown out,
and as the shuttle arrives at the end of its stroke, the bolt, remaining out, comes

page_text: in contact with a lever, thereby actuating any ordinary device for stopping the
loom.
Instead of having the upper part of the batten fixed and the lower part
oscillating, as described in the Specification before referred to, the upper fixed
part may be dispensed with entirely, or the upper and lower parts can both be
arranged to oscillate, the two parts being actuated by a cam or cams and suitable
levers or other mechanism, and having a differential movement so that when the
batten is in its forward position, beating up the weft thread, the two parts are
in coincidence with each other, after which the two parts move backwards together
until the warps have crossed, the upper part of the batten is then arrested, and
the lower part continues to move backward, thus leaving between the parts a
space for the passage of the weft finger of the shuttle, which passes through,
laying the weft in front of the batten, after which the lower part moves forward
until it again comes in coincidence with the upper part, when the whole of the
batten moves forward together to beat up the weft just laid.
Between the batten and the take-up rollers is placed a guide for the fabric
up to which the batten beats, the said guide consisting of a fixed plate and a
movable plate, the movable plate being pressed against the fixed plate by a spring
so as to put a light pressure upon the fabric which passes between the plates, and
the movable plate is provided with a suitable cam device for raising it from the
fixed plate when desired.

1, JOHN POYSER, of Peck's Hill, Sherwood Road, Mansfield, in the County of
Nottingham, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to looms for weaving and chiefly to high speed looms of
the kind described in the Specification of former Letters Patent No. 15431 of 1893
and comprises the improvements hereinafter described whereby the construction of
such looms is simplified and their efficiency increased.

loom illustrated in Figures 4 to 7.
Figures 9 to 29 are drawn to a larger scale than Figures 1 to 8.
Similar reference letters indicate corresponding parts throughout the drawings.
According to the present invention a single picker-lever a, Figures 1, 2, 5 and 6,
is provided pivoted to the base b of the loom, and having a roller a' (or projection)
engaging in the groove of a came upon the driving shaft d so that as the said shaft
revolves the lever vibrates upon its pivot. To the upper or free end of the picker-
lever a are pivoted two radial pickers a³, a², each of which is provided at its free
end with a roller a³ (or projection) adapted to engage in a cam slot or groove a
formed in the frame b' of the loom, or in an independent plate attached to the loom.
The pickers are each provided with a tooth a projecting upwards between the
sides 63, of the shuttlc-race and adapted to engage in a recess as in the shuttle e
when the picker is raised by the action of the cam slot at upon the roller a
(or projection) and to be clear of the warp threads when lowered by the same, and
the cam slot a¹ is so arranged that the teeth of the pickers engage alternately with
the shuttle, each picker being raised into engagement before the other is lowered
out of engagement so that the shuttle is passed backwards and forwards through
the shed in a positive manner when the picker-lever is vibrated by the cam c.
Figures 1 to 3 illustrate a loom having a curved shuttle race, the curve being the
arc of a circle described from the centre of the pivot of the lever a whilst Figures 4
to 8 illustrate a loom having a straight shuttle race.
The heald or heddle bars are each advantageously formed as shewn in Figures 9
and 10 by rivetting together two strips f,f of sheet metal by means of two
rivets ƒ', ƒ¹ in the centre of the strips, a space being left between the rivets for
the warp, the rivets and the sides of the strips thus forming an eye. The ends of
the strips f, f are separated by distance pieces f, f, the whole being connected
together by rivets or in any other suitable manner. This construction allows of
the bars being arranged closer together than heretofore in the heald frames, and
of the friction being at the same time reduced between the bars and the warp
threads, the said bars having parallel sides, instead of being enlarged at the eye as
heretofore. Instead of the rivets f¹, the distance pieces f", f" are sometimes
extended nearly to the centres of the strips f, f, just leaving sufficient space
between them for the passage of the warps.
The warp take-up rollers g, g, instead of presenting metal surfaces to cach
other as heretofore, are arranged as follows, that is to say, the roller is faced or
covered with powdered emery or any similar substance so as to form a rough
surface, and the other g¹ with india-rubber, leather or other soft material, the two
being held together by means of a spring not shewn and provided with any suitable
device also not shewn for throwing them out of contact when required. Instead of
using the roughened roller g described a fluted roller can be used.
In order to permit of regulating the feed movement of the take-up rollers g, y'
the following arrangement is advantageously employed in lieu of that described in
the said former Specification, that to say, the clutch lever for operating the
clutch on the spindle of one of the rollers g, g' instead of being directly operated

page_text: by a cam is connected by a link to an adjustable clamping screw and nut ³ in a
slotted lever, Figure 1, worked by a cam upon the shaft d, the amount of
movement of the rollers g, g' and the consequent feed of the warp being varied by
adjusting the said clamping screw and nut in the slot of the said lever. Instead of
a slot in the lever * a series of holes h, Figures 4, 11 and 12, is employed and a
boss to which the link 2 is connected and which slides upon the lever . The
said boss has screwed therein a screw which when turned by a suitable tommy
or key h³, Figures 13 and 14, can be engaged with either of the holes h³.
In order to take up or compensate for the slack of the warps at the closing of
the shed, a lever or frame i, Figures 1 and 3, is employed, carrying at each end a
warp guide-roller ¹, and pivoted at its centre upon a fixed spindle ³, the warps
being passed from the let-off rollers, under one guide-roller and over the other
to the healds or beddles. Or a single compensating roller may be arranged in the
frame pivoted at one end, as shewn in Figure 4. In either case the compensator
is acted upon by a spring or springs so as to cause it to bear upon the warps and
take up the slack, at the same time maintaining an even tension of the threads.
In the arrangement illustrated in Figures 1 and 3, the spring is a coil contained
within the hollow pivot boss of the frame i and encircling the spindle, one end of
the spring being connected to the said spindle and the other connected to the boss,
whilst in the arrangement illustrated in Figures 4 and 7 the springs (which are
coil springs in tension and two of which are employed) are connected to the lower
ends of the frame i and to the frame carrying the let-off rollers ³, it.
25
The guide rollers of the compensator are advantageously formed of smooth
spindles pivoted loosely in the compensator frame, and having thin discs 7, 7 of
metal threaded loosely upon them and kept within the required width when desired
by means of collars at the ends as at i*, Figure 8. The warps are passed over, the
rollers with the discs between them, and the warps are thus guided and prevented
from rubbing together.
The let-off rollers ³, are constructed similarly to the take-up rollers 9, 9' and
the frame which carries them is fixed to the bed of the loom and preferably carries
also the spindle 2 of the compensator. The warps are passed from the warp beam,
or preferably from separate cops or bobbins (not shewn) beneath the table or bed
of the loom, through a suitable guide j, and between the let-off rollers ³, to the
compensator. The let-off roller is preferably of large diameter and provided
with a brake k of any convenient construction.
In Figures 1 and 3 the brake k is illustrated as consisting of two double ended
levers pivoted to the frame and connected together at one end so as to bear upon
the roller and form the brake proper, the other ends of the levers bearing against
the boss of the compensator frame i. In Figures 4, 7 and 8, the brake k is
illustrated as consisting of a single ended lever pivoted to the frame is and curved
so as to fit and bear upon the surface of the roller i³.
The brake is pressed upon the roller 3 by means of a spring or springs k¹, k¹ and
acted upon by means of cams or projections 2 upon the pivot boss of the
compensator i so that when the shed is closed and the said compensator is pulled
backwards by its spring or springs, the brake k holds the roller 3 firmly, whereby
both of the rollers are prevented from feeding forward; when, however, the shed
is opened and the compensator is pulled forward against the pressure of its spring
or springs, the cams or projections 2 hold the brake off the roller i³ and allow both
rollers to revolve, and the warps being pulled forward by the take-up rollers, the
backward movement of the compensator due to the closing of the shed permits the
brake to return to the roller.
The let-off rollers are provided with any suitable devices for adjusting their grip
upon the warps, for instance, in Figures 1 and 3 the roller is shewn as adapted to
be pressed against the roller 3 by rods I, l one end of each of which is connected to the
spindle upon which the roller revolves while the other end (which is screw-threaded)
passes through a lug upon the frame and is held and adjusted by a nut l³,
Links support the roller

page_text: In Figures 4, 7 and 8 the roller is carried between two arms of a frame 1³
pivoted at to the frame is, the said frame 13 being caused to press the roller i*
against the roller by means of a set-screw 1, a spring 1 being interposed between
the screw and the frame so that a yielding pressure is produced.
By these described arrangements the rollers 3 and 4 can be separated when
required. In some cases one of the rollers 3, 4 is positively actuated by means of
a friction pawl or clutch m, Figure 15, similar to that for actuating the take-up
rollers. The lever m¹ of this clutch is connected by a rod m² to the clutch-lever h
of the take-up rollers, the parts being of such proportions that the amount of the
let-off corresponds with that of the take-up.
The shuttle e of the loom is provided with a projecting finger e¹ for laying the
weft thread and with a take-up lever e² which may be either a spring-lever as
hitherto (shewn in Figures 3 and 16) or actuated positively as shewn in Figure 17
by means of a cam slot or groove e³ in one of the sides of the shuttle-race. The
said cam slot or groove which is not continuous but formed in the two parts of the
shuttle-race engages with a projection et upon the under side of the take-up lever
and working through a slot ex and is of such a shape as to maintain an even tension
of the weft thread while in engagement with the said projection, the tension being
maintained when the projection is out of engagement with the slot by the projection
bearing against one end of the slot €**.
With the shuttle spool es, Figures 3 and 16, is also combined a friction brake e
which is mounted upon a brake lever e² and kept against the spool by means of a
spring so as to prevent the spool revolving when the take-up lever
is in its
backward position and taking up the slack; when, however, the take-up lever is
pulled by the weft into its forward position, that is to say, when the shuttle is at
or near the end of its stroke, a cam or projection e' upon the lever e² bears against
the brake lever e so as to remove the brake from the spool, and allow the required
amount of weft to be drawn out.
Instead of adapting the shuttle to receive a spool it can be arranged to receive
a cop (or ball) as shewn in Figures 4 to 7 and 18 to 22. In Figures 4 to 7,
18 and 19 the cop spindle 10 is normally arranged in line with the eyes ell, ell
described in the said former Specification for the passage of the weft thread, while
in Figures 20 to 22 the cop is arranged in a casing e2 with its spindle normally
parallel with the direction of movement of the shuttle.
In order that the cop can be placed upon the said spindle e the latter is hinged
as shewn at e¹³ upon the shuttle so that it can be turned into a position suitable for
such purpose. is a spring catch which engages with a notch in a flange els on
the cop spindle so as to hold the latter in its normal position, the catch shewn in
Figures 18 and 19 being depressed to release the spindle when turning the latter
on its hinge, while the catch shewn in Figures 20 to 22 is operated by a push-
piece e¹ for the same purpose.
In conjunction with the spring take-up lever e² an arrangement is provided
whereby the loom is stopped on the breaking of the weft thread. This arrange-
ment is shewn in Figures 5, 7 and 19 and consists of a sliding bolt n upon the
shuttle e adapted when the thread breaks to operate a lever o on a spindle o¹,
Figures 5 and 7, in connection with mechanism for stopping the loom. The bolt n
engages with the spring take-up lever e² by means of a projection n' or otherwise
so that when the take-up lever is in its forward position, corresponding to the end of
the shuttle's stroke, the bolt n is moved so as not to project beyond the side of the
shuttle; when, however, the take-up lever is in its extreme backward position, the
bolt projects beyond the shuttle. If, therefore, the weft thread breaks, the take-up
lever is moved by its spring into the backward position, and the bolt n con-
sequently moved so as to project beyond the side of the shuttle and as the latter
arrives at the end of its stroke, the projecting bolt comes in contact with and moves
the lever o. A suitable form of mechanism in connection with the said lever for
stopping the loom comprises a disc p on the driving shaft pl of the loom provided
with a projection p² adapted to engage with a similar projection p³ upon the driving

page_text: pulley g.
The pulley g is normally held in engagement with the disc p against
the pressure of a spring q¹ by one end of a pivoted catch q2 through the medium
of a bell crank lever g and hooked bolt q', the said catch engaging beneath the
hook of the said bolt q. One arm of the lever q3 is forked and carries friction
rollers q which press against the boss of the driving pulley 9. To the other end
of the catch is connected a crank upon the spindle o'. By this construction it
will be seen that when the weft thread breaks and the bolt n consequently projects
from the shuttle so as to move the lever o and turn the spindle o¹ the crank r will
be moved and operate the catch g2 to release the bolt q* and consequently allow the
driving pulley g to be moved out of engagement with the disc p by means of the
spring q. s is a fixed brake block with which the side of the pulley 9 comes into
contact when moved by the spring g' as described to ensure the instantaneous
stopping of the loom.
The lever q³ is provided with an additional arm 7 whereby it may be actuated
so as to start the loom again by a suitable treadle, not shewn, through the medium
of a rod g' attached to the said arm q.
The catch g2 can also be operated to stop the loom upon a warp thread breaking
and for this purpose a number of plates t, t (corresponding to the number of warps)
are provided having slots t¹ and sliding upon pins 2, carried on brackets (3
attached to a cross-bar t½ on the compensator i. The plates t are provided with
springs to, pressing against the cross-bar t* and with hooks to, to adapted to engage
with the warp threads as shewn in Figure 4. The plates t are held in the position
shewn, by the warps against the pressure of the springs to so that upon the breaking
of a warp the plate held by it is released, and being pressed forward by its spring,
actuates (upon the next backward movement of the compensator) a lever u pivoted
on the pin and connected by a rod u² to the catch q which is thereby operated
to stop the loom.
Instead of the sliding bolt n the take-up levere is sometimes arranged to
directly operate the lever o. For this purpose the said take-up lever is provided
with a projection o² as shewn in Figure 20, which projection, when the take-up
lever e is in its extreme backward position by reason of the breaking of the weft
thread, projects beyond the side of the shuttle as indicated by the dotted lines in
the said figure. This extreme backward position is determined by a stop o³ with
which the projection o² comes into contact.
Instead of having the upper part of the batten fixed and the lower part oscil-
lating, as described in the Specification before referred to, the upper fixed part
may be dispensed with entirely, or the upper and lower parts cau both be arranged
to oscillate. This latter arrangement is illustrated in Figures 4, 6, 23 and 24, the
two parts v, v being mounted upon a spindle v², the part v being connected to the
spindle while the part is free to turn thereon. The surfaces of the plates or
teeth of the two parts of the batten, adapted to come into contact, are formed at
an angle, and in such a direction, that, when the lower part is moving forward it
moves the part with it when in contact against the pressure of a spring v. The
part is actuated by a cam w, rod w¹ and lever w³, Figure 7, attached to the
spindle in a manner similar to the batten described in the said former Specifica-
tion.
The two parts v, v¹ have a differential movement so that when the batten is
in its forward position, beating up the weft thread, the two parts are in coincidence
with each other, after which the two parts move backwards together until the
warps have crossed. The upper part of the batten then comes against, and is
arrested by a stop and the lower part v continues to move backward, thus leaving
between the parts a space for the passage of the weft finger e' of the shuttle e,
which finger passes through, laying the weft in front of the batten, after which the
lower part moves forward until it again comes in coincidence with the upper
part, when the whole of the batten moves forward together to beat up the weft
just laid.
Between the batten and the take-up rollers is placed a guide a, Figures 1, 3, 6
and 7, for the fabric up to which the batten beats, the said guide as shewn clearly

page_text: in the detail views, Figures 25 to 29, consisting of a fixed plate al and a movable
plate, the movable plate being pressed against the fixed plate by a spring y so as
to put a light pressure upon the fabric which passes between the plates, and the
movable plate is provided with a suitable cam lever or screw supported by a
framing on the plate for raising it from the said plate when desired.
