We MARY C. CROMPTON Administratrix of the estate of George Crompton deceased,
and HORACE WYMAN both of Worcester in the State of Massachusetts one of the
United States of America do hereby declare the nature of this invention to be as
follows:-
This invention relates to that class of loom employed in the production by power of
ingrain carpets, the object of the invention being to improve and simplify the mechanism
of that class of looms in order that the same may be run at higher speed and with
greater economy than heretofore.
The improved loom herein to be described is provided with a filling stop-mechanism
which is so constructed and operated, substantially as will be described, as to effect
the release of the shipper-lever and the disengagement of the frictional driving pulley
during that forward movement of the lay in which the fault occurred in the laying of
the filling, the stop-motion devices, during the same forward beat of the lay, actuating
a bunter to meet a projection on the lay before the reed of the lay arrives at the fell,
the movement of the lay and crank-shaft being fully arrested before the shuttle-box
pattern mechanism has been moved far enough to effect a change of shuttle, or the
Jacquard mechanism has been moved far enough to effect a change in the pattern-
cards controlling the formation of the shed.
The shuttle-box actuating mechanism of the loom herein described is adapted to
operate a series of four shuttles at each end of the lay, and the shuttle-box pattern-
surface mechanism has combined with it a controlling mechanism, the purpose and
formation of which is to automatically control both the forward and backward move-
ment of the said shuttle-box pattern-surface in such manner as to enable the shuttle-
boxes to be operated in what is known as "shot-about," or to enable two colours of
weft to be used alternately for a number of successive picks, the controlling mechanism
referred to enabling two rows of projections of the pattern-chain, one for each colour
of the "shot-about" to be used alternately as long as desired, thus saving the employ-
ment of a long pattern-surface, and preferably the time and order of movement of the
controlling-mechanism referred to will be determined by a part of the same Jacquard
pattern mechanism which controls the shedding of the warps.

page_text: The loom herein described is provided with a pair of fluted take-up rolls held
one toward the other in a yielding manner, the undermost positively driven roll of
the pair, besides its end bearings, having a central or intermediate bearing to better
support it, thus obviating any sagging of the middle of the roll which would impair
the uniformity of the draft of the roll on the carpet being woven.
We have devised and provided the power-shaft with a novel friction pulley which
avoids shipping the driving-belt from a fast to a loose pulley and enables us to stop
the loom during any forward beat of the lay.
The invention herein contained consists essentially in the combination with the lay
and breast-beam, of a filling stop-mechanism, substantially as will be described,
containing a slide bar, and a projection, a lever moved by the slide bar, a shipper
handle, a rod moved by the lever to release the shipper handle, a lever moved by the
projection, a hunter pivoted at the underside of the lay and operated by the said
projection, and a projection carried by the lay, the said parts being constructed and
arranged substantially in the manner to be herein described, whereby the shipper lever
will be released and the bunter elevated to arrest the forward movement of the lay,
all during one and the same forward beat of the lay, as set forth herein.
Also the combination with the lay, and breast-beam and a friction clutch pulley
said to impart motion to the main cam shaft of the loom, of a filling stop-mechanism
substantially as will be described, containing a slide-bar, a lever moved thereby and
a rod moved by the said lever to release the shipper handle a rod as actuated
by the shipper handle and having a projection to actuate a hub forming
part of the friction driving clutch pulley whereby the band receiving rim
of the clutch pulley is freed from the shaft driving the loom during that
forward motion of the lay in which the fault in the filling enables the dagger to fall
and actuate the slide bar of the said stop-mechanisin substantially as will be
described.
Also the combination with the shuttle box pattern surface and actuating devices
therefor, of a controlling mechanism, substantially as described under the control of a
Jacquard whereby the hub forming part of the mechanism for driving the shuttle box
pattern surface from a moving part of the loom may be automatically shifted at the
proper time to move the pattern surface backwards and forwards for a short distance
for shot about weaving substantially as will be described.
Also in an organized loom for the production of Ingrain Carpet, a shifting shuttle
box mechanism substantially as will be described having main and auxiliary levers at
the same side of the loom and having connections to operate the shuttle boxes at
opposite sides of the loom means to rotate the said pattern surface chain in one or the
other direction controlled mechanically as will be described to automatically control
the direction of rotation of the mechanism for rotating the pattern surface for the
shuttle box mechanism or Jacquard mechanism to control the formation of the sheds
a shipper lever to effect the release of the loom from the power driving it and a stop
mechanism substantially as will be described actuated by fault in the filling to release
the shipper handle substantially as will be described.

the said arms with the said pawl, a second cord to connect the other of the
said arms with a trap board of a Jacquard mechanism combined with a locking
device to act upon a finger of one of the arms of the rock-shaft to keep the pawl
elevated from the ratchet to be moved by it, and a cord connecting the said locking
device with a trap board of the Jacquard mechanism substantially as will be described
Also in the combination with the driving shaft of a loom, of a loose pulley having
an inner aunular flange, a sleeve capable of a longitudinal movement on said shaft, and
provided with a pivoted wedge, and a strap carrier secured to the shaft and having
a strap nearly encircled in the said flange, and a pair of levers pivoted to the said
strap carrier, and having jaws engaging lugs and projections at the end of the strap
whereby the strap may be made to grasp the annular flange of the loose pulley to
ensure the rotation of the said shaft, as will be described.
Herein we have omitted from the description some parts which in practice will be
as commonly employed in other looms they having been omitted to simplify the
description, their illustration being considered immaterial as not being within the
scope of this invention, and being well known and not necessary therefore to be
herein described.
The loom-frame, of suitable shape to sustain the working parts, has erected upon
a suitable frame-work, which serves to support the actuating parts of the Jacquard
mechanism employed to form sheds in the warp.
The mechanisin comprises a power shaft, a bevel pinion thereon, a toothed gear
fast on the main shaft, a gear on the crank shaft, the lay actuating shaft, the
connecting rods, a lay, a shipper lever, a notched elbow lever embracing it, a shipper
rod attached to the said elbow lever, the shuttle boxes at opposite ends of the loom
each shuttle box supported by a rod surrounded by a spiral spring, the shuttle box
actuating mechanism consisting essentially of two like shuttle box levers, radius bars
one for each shuttle box lever, auxiliary lovers pivoted upon each shuttle box lever,
pins carried by the radius bars and acting against auxiliary levers respectively below
and above their fulera, connecting rods attached one to each radius bar, toothed
cranks to which the said connecting rods are attached, vibrators, upon which the
toothed cranks have their fulera, long partial gears to engage and rotate the said
toothed gears in one and then in an opposite direction, connecting rods extending
upwards to fingers acted upon by the shuttle box pattern surface, an upright shaft,
bevel gears mounted loosely on the said shaft and having at their inner ends teeth
to form parts of a clutch, an intermediate clutching hub splined upon the shaft, a
rod to operate the said clutching hub, bevel gear in engagement with both the said
bevel gears, a co-operating pin wheel secured to and actuated in unison with the
crank shaft, toothed gear for imparting motion to the long partial gears, guides for
the lower ends of the shuttle box rods, a chain or flexible connection attached to the
shuttle box lever and extending over suitable sheaves to the shuttle box rod supporting
the series of shuttle boxes at the opposite side of the loom, picker sticks, straps to
connect them, and means for operating the picker-sticks, which are and may be all
substantially the same as described in the specification of Letters Patent No. 3655,
dated July 25th, 1883, to which reference may be had; the shuttle boxes being
operated in the proper time and order as provided for in said patent, so they need
not necessarily be further described herein.

page_text: The rod connected with the elbow lever and operated by the shipper lever has at
its end a forked finger which enters an annular groove in a hub mounted upon the
power shaft.
The power shaft has a sleeve provided with a collar which is secured to the said
shaft by a set screw. This sleeve forms a bearing for the loose pulley, a collar
preventing longitudinal play of the pulley on the said sleeve in one direction. The
loose pulley has an annular flange located between its hub and band-rim, which is
made as a separate piece bolted to the main pulley by bolts, 'so as to leave an annular
space between the annular flange and the band rim.
A strap carrier having a hub is made to encircle, and is positively secured to the
shaft by a key, so that the strap carrier rotates with the shaft, the strap carrier
holding the pulley against longitudinal motion on the sleeve away from the collar.
The strap carrier arranged preferably between the flange of the pulley, and the
shaft has at one end an arm or extension, which by a suitable bolt or bolts is secured
to a friction strap, which nearly encircles the flange and is provided at its nearly
meeting ends with studs or lateral projections.
These studs or projections are engaged by jaws of two clamping levers inde-
pendently pivoted upon the strap carrier, the said pivoted point being substantially
diametrically opposite the extension referred to, each lever being provided preferably
with an adjusting screw, which is held in adjusted position by a suitable check nut,
the said screws pass through the shanks of the levers, the rounded inner ends of the
screws lying close to and opposite each other, a sufficient space being left between
them to admit the introduction between them of a wedge, the said wedge when
forced inward between the said screws acting upon them to force the upper ends of
the said levers apart, thus causing the short ends to act upon the lateral projections of
the friction strap causing the latter to bind or clamp the annular flange, thus causing
the strap carrier to rotate in unison with the loose pulley driven by the driving band,
extended around the band-rim, rotation of the strap-carrier and friction-strap
causing the rotation of the shaft, thus driving the loom.
The wedge referred to is pivoted upon the sleeve having an annular groove, which
is entered by an arm attached to, say the outer end of the shipper rod. A spiral
spring, acts normally to draw the upper ends of the two levers towards each other or
in the direction to release the friction strap from its hold upon the annular flange, the
spring being effective when the wedge is in its farthest position away from the
pulley.
The levers are provided at their upper ends with toes which extend upward behind
a plato, secured by screws, to the extension of the strap carrier.
Adjustment of the screws measure the amount of friction between the strap and
the flange, and also compensate for wear between the said parts, and to enable the
pressure of the strap to be uniform throughout its length notwithstanding slight
inequalities in adjustment of the screws, the wedge has been pivoted. Making the
belt receiving flange separate from the pulley enables the flange to be cheaply and
conveniently turned true in a lathe.
The flange acts as a guard to prevent the wedge from catching the clothing of the
operator.
The cam shaft, near the right hand end of the loom is provided with a worm,
located thereon just outside the loom frame, the said worm engaging a worm gear ou
a shaft the outer end of which is supported in an adjustable bearing, the said shaft
having a worm which engages the worm toothed gear secured to the shaft on the
lowermost roll of the pair of fluted tak-up rolls. The number of teeth of worm
toothed gear secured to the journal of the lower roll of the takeup rolls, will be
adjusted to the picks to the inch in the carpet to be woven, and this gear will be
changed whenever the picks to the inch are to be more or less; in such
case, however the shaft having the worm will be adjusted in its bearings so
to provide for the employment of a gear of different diameter.
worm gear on the shaft forms part of a sleeve having an attached hand-whee
which is mounted loosely upon the shaft the said sleeve or
a part of the
as
The

page_text: hand-wheel being engaged by a locking device herein shown, as a spring
pressed pin extended through a hub fixed to the outer end of the shaft by a set
screw. When the said locking device then engages the said sleeve or the hand
wheel, the worm is fixed with relation to the shaft but if it should be desired to
rotate the said take-up rolls while the shaft is at rest or to rotate the take-up rolls at a
different speed, the said locking device will be withdrawn thus leaving the sleeve and
the worm thereon loose on the shaft and free to be rotated by the hand wheel. The
lowermost take-up roll has suitable bearings near each end, but the lowermost or the
driven roll of the pair of take-up rolls will be provided near its centre, with an annular
groove forming a neck to be embraced by a bearing forming part of a bracket attached
to the under side of the breast beam the said bearing operating to prevent sagging or
springing of the roll between its ends. The upper roll of the take-up rolls has its
end bearing in boxes forming parts of levers pivoted at the inner ends of the said
levers being acted upon by suitable springs or equivalents the normal tendency of
which is to force roll toward roll, the said rolls being rotated however in unison by a
pinion attached to the lower roll, it engaging a pinion attached to the upper roll.
The carpet after leaving the take-up rolls is wound upon a receiving roll having its
bearings in stands attached to the loom-sides, the said receiving roll having attached
to its shaft a toothed gear engaged and rotated by a pinion forming part of a ratchet
toothed wheel mounted loosely on a stud projecting from a stand secured to the loom-
side, the said ratchet toothed gear being engaged and rotated intermittingly by the
pawl pivoted upon the upper end of a pawl-carrier pivoted the said pawl carrier having
an arm or projection which at each backward movement of the lay is acted upon by
a pin or stud made adjustable in slots in the lay sword, the forward movement of the
pawl carrier and pawl and consequently the movement of the receiving roll depending
upon the force of a spring secured to the pawl carrier and to a stud fixed to the loom
frame. Suitable detents prevent retrograde movement of the ratchet wheel. Referring
to the shuttle-box actuating mechanism, the upper end of the shaft has a bevel gear
which engages a bevel gear on a short shaft having at its other end a toothed gear
which through an intermediate engages a tooth gear fast on and rotating the shaft.
carrying the pattern-surface to control the order of shifting of the shuttle-boxes.
Each vibrator has a connecting rod extending upwards from it, each rod being
connected to a finger having its fulcrum on a stud extended across the yoke-like frame
pivoted upon studs said frame being held down by a suitable spring and being free to
rise should the toothed cranks or their operating devices or connections fail to work,
thus obviating breakage of parts.
The usual rolls of the pattern-surface referred to act in the proper sequence upon
the several fingers to lift or to permit one of the vibrators to rise or fall in what is
known as "shot about" weaving or when weaving a pattern wherein two colors for
two shuttles are to be inserted alternately. It is of very great convenience to be able
to rotate the shuttle-box pattern-surface forward and then backward so that any two
bars may be operated in succession for any desired number of picks. For such change
of movement of the shuttle-box pattern surface, the rod for shifting the clutching hub
has been provided with a collar, having a stud which enters a slot in one arm of a
lever having its fulcrum on a stand secured to the loom-side, the other arm of the
said lever having a roller or other stud, which enters a cam groove, in a face cam
secured to a short sleeve having at its outer end a hand wheel the sleeve between the
hand wheel and cam having a ratchet wheel having say four teeth, the said sleeve
also having attached to it at the rear of the face cam a holding drop or wheel with
which co-operates a roll on a radius bar pivoted, the said radius bar being acted upon
by a spring, the said roll resting in a recess of the holding wheel and maintaining
the sleeve and cam and ratchet in any position where it may be left. The rod has fast
to it two collars, between which and the loose collar are placed like spiral springs.
As the lever is moved by the face cam the collar acting upon one or the other of the
springs on the rod, lifts or depresses as it may be the said rod, and causes the clutching
hub having teeth at each end to engage one or the other of the toothed ends of the
hubs of the bevel gears, which effects the rotation in one or the other direction of the

page_text: shaft, and through the gearing described the shaft of the pattern surface for the shuttle-
boxes. The sleeve carrying the cam derives its step by step rotation from the pawl pivoted
upon a pawl carrier pivoted to the loom frame, the lower end of the said pawl carrier
being acted upon once during each rotation of the crank-shaft by means of a stud, at
the face of the pin-wheel before referred to.
The lower end of the said pawl-carrier being normally held toward the said pin by
a spiral spring.
The groove in the face cam is of such shape as to move the lever far enough at each
movement to effect the disengagement of the clutching hub from one of the bevel
gears referred to, and its engagement, with the other bevel gear, but if desired the
shape of the said cam may be so modified as to leave the clutching hub in central
position between the clutching teeth of the bevel gears and to thus leave the shaft
at rest for any desired number of picks. The mechanism referred to for shifting the rod
to effect the rotation in one or the other direction of the pattern-surface for the shuttle
box motion is herein denominated as the controlling mechanism for the pattern-surface,
and instead of the specific devices described we may employ any other well known and
equivalent devices for effecting a like purpose. The reversal of movement of the
shuttle-box pattern-surface is herein made automatic, entirely so, and is placed under
the control of one of the cards of the Jacquard mechanism as will now be described.
The pawl has connected to it a cord which is extended upward where it is attached
to an arm the said arm being weighted and projecting in the same direction as the
pawl, all co-operating to turn the said rock-shaft. The arm at the inner end of the
rock-shaft has attached to it a cord which is extended upwards through a hole in
the usual guide-board ibence through one of the usual needles and through a hole in
one of the usual trap boards, above which it is attached to a top board the said cord
extended through the trap board having a cord to be trapped through the operation of
the Jacquard cards on the needles so that the cord may be lifted whenever desired.
The arm referred to, at its inner end has a bevel finger and a lug the latter serving
merely as a stop for the rock-shaft when turned. The bracket or stand in which the
rock-shaft has its bearing is provided with a stud upon which is pivoted a locking
device having an arm which co-operates with the bevel finger of the arm the said
locking device having a cord which co-operates in like manner with the trap bourd.
The crank shaft just behind the toothed gear is provided with a bevel gear which
engages a bevel gear on and rotates a shaft having at its upper end a small bevel
gear fast to one end of the main shaft of the Jacquard mechanism, the said shaft
having fast to it near each end a series of cams, which at each rotation of the said
shaft act in succession upon a series of levers connected by rods with the usual journals
which act upon the knots of the Jacquard harness to lift the same or permit the
harness to drop in the formation of sheds in the warp for the passage of the shuttle.
The Jacquard or tail cords are attached to harness cords a number of which, attached
to each tail cord, pass through holes in the usual journals, the journals in their rising
movement acting upon knots in the harness cords and forming the shed, the trap-
boards and journals operating in usual manner to form the sheds for the Ingrain
figures.
The main shaft of the jacquard has attached to it a toothed gear which engages and
rotates a toothed pinion mounted on a suitable stud and having a crank or wrist upon
which is fitted a connecting rod the upper end of which in turn engages a pin, of a
crank on the shaft the said shaft having attached to it two like cross arms which
by links are joined to like slides carrying the usual trap-boards. The jacquard cords
will be supported from the top board and extend down through a hole in one of the
trap boards through an eye of a jacquard needle, the series of needles arranged in
usual manner being actuated by a series of jacquard cards carried by a lantern or
other wheel rotated in usual manner, all the said devices acting in usual manner to
move the warps to form sheds, the said lantern wheel is mounted in boxes at the ends
of slide rods actuated by arms attached to a rock-shaft having an arm, extended
backward from the loom and attached by links to one end of a lever which is moved
by a cam, secured to the main shaft of the jacquard, said cam acting upon a roller or

page_text: other stud projecting from the side of the said arm. A pawl engaging studs at the
end of the lantern wheel rotates the same intermittingly. Instead of jacquard
mechanism other usual or well known mechanism for like purpose may be used.
If the ratchet wheel and the part associated is to be engaged and moved step by
step by the pawl then the cord and its devices would be unnecessary.
When the pawl is to engage the ratchet wheel to which the said cam attached to
the sleeve carrying the said ratchet and at such times the arms occupy their lowest
position. When the pawl is to be lifted, a jacquard card through a jacquard needle
moves the cord lifts the arm, turns the rock shaft and lifts the arm and by the cord
the pawl lifted. As the arm is lifted the finger is shifted and as soon as the finger
passes below the short arm of the locking device permits the spring to move the
tacking device into position the locking device holding the arm elevated and the pawl
out of the range of movement of the ratchet wheel.
With the parts in this position to permit the pawl to be lowered to engage the
ratchet wheel, it is only necessary to lift the arm in the proper direction until the
short arm thereof passes beyond the end of the finger, the locking device sliding off
the end of the said finger leaving the weighted ends of the arms to descend until the
finger meets the stop.
The lay, at its rear side near the ends of the reed, is provided with brackets which
receive a rock shaft to the ends of which outside the said brackets are attached two
feelers. The arm of the feeler near say the right hand of the loom, has attached to
it a rod which is extended down and joined to a lever pivoted, the rear end of the said
lever being acted upon by a double throw cam secured to the cam shaft, the said cam,
lever, and rod, serving to raise and lower the fecler positively at the proper time
during each beat of the lay to feel for the filling. The brackets referred to have
each a suitable stud upon which is pivoted a like grid. Each grid, is connected by a
link with an arm of a dagger shaft having suitable bearings at the under side of the
lay and provided with a dagger, the said dagger shaft having an arm which is acted
upon by a spring attached to the under side of the lathe, the said spring normally
keeping the dagger with its forward end depressed and the grid elevated so that
whenever the filling is properly laid across the grid end and the filling fork descends
upon the filling the grid will be depressed and through the link turn the dagger
shaft and lift the dagger so that it will not affect the stopping of the loom as it would
otherwise do. The dagger shaft has secured to it a stop which limits the movement
to the said rock shaft under the action of the spring. Should the filling be absent or
at fault and the grid be not depressed by the filling fork, then the dagger attached to
the dagger shaft, will meet a dog pivoted upon a slide bar and will move the said
slide bar longitudinally in a guide supported from the inner side of the breast beam,
and will cause the outer end of the said slide bar to strike a lever mounted upon a
stud at the lower side of the breast beam and will turn the said lever so as to act upon
a lug connected to the slide rod moving it longitudinally to the right to effect the
release of the shipper lever from its holding notch of the plate. As the dog engaged
by the dagger is moved an inclined part of the dog below its fulcrum acts upon a roll,
supported by the guide, causing the dog to be tipped on its centre releasing it from
the dagger but not until after the shipper lever has been released from the notch in
the holding plate. The slide bar has attached to it a finger which in the forward
movement strikes the end of the bunter operating lever pivoted at the under side of
the breast beain, causing a finger, at the opposite end of the said lever, to strike
against the outer beveled end of the bunter lever, pivoted on a yoke thus lifting
the inner notched end of the said lever and placing in the line of approach of the
bunter or stop, projecting from a block secured to the under side of the lay,
the said projection entering the notch in the inner end of the bunter lever before
the lay in its forward movement, (the shipper lever having been released,) brings the
reed of the lay to the fell thus completely stopping, the lay during that forward
movement of it in which occurs the fault in the filling. As soon as the shipper lever
is released and before the bunter or stop comes into operation to stop the forward
movement of the lay, the hub or the friction pulley has been operated to withdraw the

page_text: wedge thus releasing the strap separate its parts, leaving the pulley free to move with
the belt, the latter running with the loose part of the friction pulley.
The loop shaped stand on which the bunter lever is pivoted is free to slide to a
limited extent upon a bolt or pin held in suitable ears or bearings, a block of rubber,
or other suitable spring, being applied between one of the arms of the slide block and
one of the cars the rubber or other spring avoiding injurious shock and by its rebound
giving a slight recoil to the lay to throw it back into such position as to enable the
operator to readily reach the broken or misplaced filling.

Improvements in Looms for the Production of Carpets and like
Fabrics.
We MARY CHRISTINA CROMPTON, Administratrix of the estate of George Crompton,
deceased, and HORACE WYMAN both of Worcester in the State of Massachusetts one
of the United States of America, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to that class of loom employed in the production by power
of ingrain carpets, the object of the invention being to improve and simplify the
mechanism of that class of looms in order that the same may be run at higher speed
and with greater economy than heretofore.
The improved loom herein to be described is provided with a filling stop-mechanism
which is so constructed and operated, substantially as will be described, as to effect
the release of the shipper-lever and the disengagement of the frictional driving pulley
during that forward movement of the lay in which the fault occurred in the laying of
the filling, the stop-motion devices, during the same forward beat of the lay, actuating
a hunter to meet a projection on the lay before the reed of the lay arrives at the fell,
the movement of the lay and crank-shaft being fully arrested before the shuttle-box
pattern mechanism has been moved far enough to effect a change of shuttle, or the
jacquard mechanism has been moved far enough to effect a change in the pattern-cards
controlling the formation of the shed.
The shuttle-box actuating mechanism of the loom herein described is adapted to
operate a series of four shuttles at each end of the lay, and the shuttle-box pattern-
surface mechanism has combined with it a controlling mechanism, the purpose and
formation of which is to automatically control both the forward and backward move-
ment of the said shuttle-box pattern-surface in such manner as to enable the shuttle-
boxes to be operated in what is known as "shot-about," or to enable two colours of
weft to be used alternately for a number of successive picks, the controlling
mechanism referred to enabling two rows of projections of the pattern-chain, one for
each color of the "shot-about to be used alternately as long as desired, thus saving
the employment of a long pattern-surface, and preferably the time and order of move-
ment of the controlling-mechanism referred to will be determined by a part of the
same jacquard pattern mechanism which controls the shedding of the warps.
The loon herein described is provided with a pair of fluted take-up rolls held one
toward the other in a yielding manner, the undermost positively driven roll of the
pair, besides its end bearings, having a central or intermediate bearing to better
support it, thus obviating any sagging of the middle of the roll which would impair
the uniformity of the draft of the roll on the carpet being woven.
We have devised and provided the power-shaft with a novel friction pulley which
avoids shipping the driving belt from a fast to a loose pulley and enables us to stop
the loom during any forward beat of the lay.

page_text: The invention herein contained consists essentially in the combination with the lay
and breast-beam, of a filling stop-mechanism, substantially as will be described,
containing a slide bar, and a projection, a lever moved by the slide-bar, a shipper
handle, a rod moved by the lever to release the shipper handle, a lever moved by the
projection, a bunter pivoted at the underside of the lay and operated by the said pro-
jection, and a projection carried by the lay, the said parts being constructed and
arranged substantially in the manner to be herein described, whereby the shipper
lever will be released and the bunter elevated to arrest the forward movement of
the lay, all during one and the same forward beat of the lay, as set forth herein.
Also the combination with the lay, and breast-beam and a friction clutch pulley
substantially as described to impart motion to the main cam shaft of the loom, of a
filling stop-mechanism substantially as will be described, containing a slide-bar, a
lever moved thereby and a rod moved by the said lever to release the shipper handle,
and a rod actuated by the shipper handle and having a projection to actuate a hub
forming part of the friction driving clutch pulley whereby the band receiving rim of
the clutch pulley is freed from the shaft driving the loom during that forward motion
of the lay in which the fault in the filling enables the dagger to fall and actuate the
slide bar of the said stop-mechanism substantially as will be described.
Also the combination with the shuttle box pattern surface and actuating devices
therefor, of a controlling mechanism, substantially as described under the control of
a jacquard whereby the hub forming part of the mechanism for driving the shuttle
box pattern surface from a moving part of the loom may be automatically shifted at
the proper time to move the pattern surface backwards and forwards for a short
distance for shot about weaving substantially as will be described.
Also in an organized loom for the production of ingrain carpet, a shifting shuttle

Herein we have omitted from the drawings some parts which in practice will be
as commonly employed in other looms they having been omitted to simplify the
drawings, their illustration being considered immaterial as not being within the scope
of this invention, and being well known and not necessary therefore to be herein
described.
The loom-frame A, of suitable shape to sustain the working parts, has erected upon

the shipper rod A' attached to the said elbow lever, the shuttle boxes 30 and 30 at
opposite ends of the loom each shuttle box supported by a rod d', surrounded by a
spiral spring d³, the shuttle box actuating mechanism consisting essentially of two like
shuttle box levers e and go having their fulcra at e², the radius bars 31 and 32 one for each
shuttle box lever e and go, the auxiliary levers e pivoted as at 28 upon each lever e
and go the pins 35 and 36 carried by the radius bars and acting against the auxiliary
levers e respectively below and above their fulcra 28, the connecting rods e** attached
one to each radius bar, the toothed cranks c, to which the said connecting rods are
attached, the vibrators 10, 12, upon which the toothed cranks have their fulcra, the
long partial gears c, c, to engage and rotate the said toothed gears in one and then in
an opposite direction, the connecting rods e extend upwards to fingers acted upon by the
shuttle box pattern surface, the upright shaft the bevel gears 6 and a mounted
loosely on the said shaft and having at their inner ends teeth to form parts of a clutch,
the intermediate clutching hub & splined upon the shaft b¹, the rod 6º to operate the
said clutching hub, the bevel gear a in engagement with both the said bevel
gears and a¹, the co-operating pin wheel a' secured to and actuated in unison with
the crank shaft A', the toothed gear d for imparting motion to the long partial
gears c, c, the guides el for the lower ends of the shuttle box rods, the chain or flexible
connection g² attached to the shuttle box lever g and extending over suitable sheaves
as g³ to the shuttle box rod supporting the series of shuttle boxes u30 at the opposite
side of the loom, the picker sticks h, the straps to connect them, and means for
operating the picker-sticks, are and may be all substantially the same as described in
the Specification of Letters Patent No. 3655, dated July 25th, 1883, to which reference
may be had, and wherein like letters are employed to designate like parts; the shuttle
boxes being operated in the proper time and order as provided for in said patent, so
they need not necessarily be further described herein.
:
The rod A' connected with the elbow lever A and operated by the shipper lever A
has at its end a forked finger which enters an annular groove in a hub mounted upon
the shaft Aº.
Referring to sheet Figs. 13, 14, and 15, the shaft A has a sleeve K¹ provided
with a collar K2 which is secured to the said shaft by a set screw K³. The sleeve K¹
affords bearing for the loose pulley k*, the collar k² preventing longitudinal play of the
pulley on the said sleeve in one direction. The pulley k has an annular flange k
located between its hub and band-rim ke, which as herein shewn is made as a separate
piece bolted to the main pulley by bolts k, so as to leave an annular space between
the annular flange and the band rim.
A strap carrier having a hub k is made to encircle, and is positively secured to
the shaft A by a key 10, so that the strap carrier rotates with the shaft A, the strap
carrier holding the pulley against longitudinal motion on the sleeve k¹ away from
the collar 12.
The strap carrier arranged preferably between the flange of the pulley, and
the shaft A has at one end an arm or extension, as 12, see Fig. 13, which by a
suitable bolt or bolts ¹³ is secured to a friction strap 4, which nearly encircles the
flange and is provided at its nearly meeting ends with studs or lateral projections 16
see Fig. 15.
The studs or projections are engaged by jaws of two clamping levers
independently pivoted upon the strap carrier at 18, the said pivotal point being
substantially diametrically opposite the extension 12 referred to, each lever being
provided preferably with an adjusting screw, as 10, which is held in adjusted position
by a suitable check nut, as represented in Fig. 14, the said screws pass through the
shanks of the levers k, the rounded inner ends of the screws lying close to and
opposite each other, a sufficient space being left beween them to admit the introduc-
tion between them of a wedge, as 20, the said wedge when forced inward between
the said screws acting upon them to force the upper ends of the said levers apart,
thus causing the short ends 16 thereof to act upon the lateral projections of the
friction strap causing the latter to bind or clamp the annular flange ko, thus causing

page_text: the strap carrier to rotate in unison with the loose pulley 4 driven by the driving
band, not shown, extended around the band-rim k, rotation of the strap-carrier and
friction-strap causing the rotation of the shaft A, thus driving the loom.
The wedge referred to is pivoted at 21 upon the sleeve having an annular
groove, see Fig. 1, which is entered by an arm 23 attached to, as herein shown,
the outer end of the shipper rod A'. A spiral spring, as 24, see Fig. 15, acts normally
to draw the upper ends of the two levers " towards each other or in the direction
to release the friction strap 4 from its hold upon the annular flange, the spring
being effective when the wedge 20 is in its farthest position away from the pulley *.
The levers are provided at their. upper ends with toes 25 which extend upward
behind a plate ², secured by screws, as k², to the extention 12 of the strap
carrier 8.
;
Adjustment of the screws ¹ measure the amount of friction between the strap k
and the flange, and also compensate for wear between the said parts, and to enable
the pressure of the strap to be uniform throughout its length notwithstanding slight
inequalities in adjustment of the screws, the wedge has been pivoted as
shown.
Making the belt receiving flange 4 separate from the pulley & enables the flange k³
to be cheaply and conveniently turned true in a lathe.
The flange acts as a guard to prevent the wedge from catching the clothing
of the operator.
AL
The cam shaft A³, near the right hand end of the loom is provided with a worm 8
see Fig. 1, located thereon just outside the loom frame, the said worm engaging a
worm gear B on a shaft B the outer end of which is supported in an adjustable
bearing B², the said shaft having a worm B³ which engages the worm toothed gear B
secured to the shaft on the lowermost roll B of the pair of take-up rolls B and B
both of the said rolls being fluted. The worm toothed gear B* secured to the journal
of the lower roll of the take up rolls, will in practice have as many teeth as there are
to be picks to the inch in the carpet to be woven, and in practice this gear will be
changed whenever the picks to the inch are to be more or less; in such case, however
the shaft B having the worm B3 will be adjusted in its bearings so as to provide for
the employment of a gear of different diameter. The worm gear B3 on the shaft B₁
forms part of a sleeve having an attached hand-wheel B' which is mounted loosely
upon the shaft B the said sleeve or a part of the hand-wheel being engaged by
locking device herein shown, as a spring pressed pin B extended through a hub B
fixed to the outer end of the shaft B' by a set screw B. When the said locking
device thus engages the said sleeve or the hand wheel, the worm B³ is fixed with
relation to the shaft B₁ but if it should be desired to rotate the said take-up rolls
while the shaft B' is at rest or to rotate the take-up rolls at a different speed, the said
locking device will be withdrawn thus leaving the sleeve and the worm B³ thereon
loose on the shaft B' and free to be rotated by the hand wheel B. The lowermost
take-up roll has suitable bearings as C near each end see Fig. 2, wherein the main
parts of the take-up rolls are broken out to save space in the drawing, but in practice
the lowermost or the driven roll B of the pair of take-up rolls will be provided near
its centre, see Fig. 6, with an annular groove forming a neck to be embraced by a
bearing forming part of a bracket Cattached to the underside of the breast beam g¹
the said bearing operating to prevent sagging or springing of the roll B³ between its
ends as is apt to be the case with a long roll, sagging or yielding of the roll pre-
venting uniformity in the action of the take-up upon the carpet from selvage to
selvage. The upper roll B of the take-up rolls has its end bearing in boxes forming
parts of lovers Opivoted at the inner ends of the said levers being acted upon by
suitable springs or equivalents (the normal tendency of which is to force the roll B
toward the roll B, the said rolls being rotated however in unison by a pinion C
attached to the lower roll B³, it engaging a pinion C attached to the upper roll B.
The carpet after leaving the take-up rolls is wound upon a receiving roll Chaving its
bearings in stands C attached to the loom-sides, the said receiving roll having attached
to. its shaft a toothed gear which in practice is engaged and rotated by a pinion (10

page_text: forming part of a ratchet toothed wheel C¹² mounted loosely on a stud C¹³ projecting
from a stand secured to the loom-side, the said ratchet toothed gear being engaged
and rotated intermittingly by the pawl C pivoted upon the upper end of a pawl-
carrier C1 pivoted at the said pawl carrier having an arm or projection C which
at each backward movement of the lay is acted upon by a pin or stud (18 made
adjustable in slots in the lay sword see Fig. 5, the forward movement of the pawl
carrier and pawl and consequently the movement of the receiving roll 07 depending
upon the force of a spring (₁ secured to the pawl carrier C and to a stud fixed to
the loom frame.
Suitable detents (20 prevent retrograde movement of the ratchet wheel. Referring
to the shuttle-box actuating mechanism, the upper end of the shaft b has a bevel
gear b² which engages a bevel gear 13 on a short shaft 14 having at its other end a
toothed gear 15 which through an intermediate 16 see Fig. 4, engages a toothed
gear 17 fast on and rotating the shaft 19 carrying the pattern-surface 20 to control
the order of shifting of the shuttle-boxes the said pattern-surface in practice being a
short chain having a series of bars provided with rolls as in the patent referred to.
Each vibrator as 10, 12, has a connecting rod e extending upwards from it, each
rod being connected to a finger as 21 having its fulcrum on a stud 22 extended across
the yoke-like frame 23 pivoted upon studs 24 see Fig. 4, the said frame being held
down by a suitable spring 25 the frame being free to rise should the toothed cranks
C or their operating devices or connections fail to work, thus obviating breakage of
parts.
The usual rolls of the pattern-surface referred to act in the proper sequence upon
the several fingers 21 to lift or to permit one of the vibrators 10, 12, to rise or fall
in what is known as "shot about" weaving or when weaving a pattern wherein two
colors for two shuttles are to be inserted alternately. It is of very great convenience
to be able to rotate the shuttle-box pattern-surface forward and then backward so that
any two bars may be operated in succession for any desired number of picks. For
such change of movement of the shuttle-box pattern-surface, the rod 6 for shifting
the clutching hub has been provided with a collar 26 see Fig. 3, having a stud
which enters a slot in one arm of a lever 27 having its fulcrum at 28 on a stand 29
secured to the loom-side, the other arm of the said lever having a roller or other
stud 30, see Fig. 4, which enters a cam groove see dotted lines Fig. 3, in a face cam 33
see full lines Fig. 7° secured to a short sleeve having at its outer end a hand wheel 34
the sleeve between the hand wheel and cam having a ratchet wheel 37 see dotted
lines Fig. 3 and full lines Fig. 7°, herein shown as having four teeth, the said sleeve
also having attached to it at the rear of the face cam see Fig. 7d a holding drop
or wheel 38 with which co-operates a roll 39 on a radius bar 40 pivoted at 41, the said
radius bar being acted upon by a spring 42, the said roll resting in a recess of the
holding wheel and maintaining the sleeve and cam 30 and ratchet 37 in any position
where it may be left. The rod 6° has fast to it two collars 43, 44, between which and
the loose collar 26 are placed like spiral springs 45. As the lever 27 is moved by the
face cam 33 the collar 26 acting upon one or the other of the springs 45 on the rod 6°,
lifts or depresses as it may be the said rod, and causes the clutching hub b having
teeth at each end to engage one or the other of the toothed ends of the hubs of the
bevel
shafts 6 or at which effects the rotation in one or the other direction of the
and through the gearing described the shaft of the pattern surface for
the shuttle boxes. The sleeve carrying the cam 33 derives its step by step rotation
from the pawl 46 pivoted at 47 upon a pawl carrier 48 pivoted at 5 to the loom frame,
the lower end of the said pawl carrier as herein shown being acted upon once during
each rotation of the crank shaft by means of a stud 49 see Fig. 3, at the face of the
pin-wheel a hefore referred to. The lower end of the said pawl-carrier being
normally held toward the said pin by a spiral spring 50.
As herein provided for the groove in the face cam 33 is of such shape as to move
the lever 27 far enough at each movement to effect the disengagement of the clutching
hub b from one of the bevel gears referred to, and its engagement with the other
bevel gear, but if desired the shape of the said cam may be so modified as to leave

page_text: b
the clutching hub in central position between the clutching teeth of the bevel gears
and a to thus leave the shaft at rest for ary desired number of picks. The
mechanism referred to for shifting the rod 69 to effect the rotation in one or the other
direction of the pattern-surface for the shuttle-box motion is herein denominated as
the controlling mechanism for the pattern-surface, and instead of the specific devices
shown we may employ any other well known and equivalent devices for effecting a
like purpose. The reversal of movement of the shuttle-box pattern-surface is herein
inade automatic, entirely so, and is placed under the control of one of the cards of
the jacquard mechanism as will now be described.
The pawl 46 see Fig. 3, has connected to it a cord 51 which see Fig 3 a is extended
upward where it is attached to an arm 54 the said arm being herein shov
hown as weighted
and as projecting in the same direction as the pawl 46, all co-operating to turn the
said rock-shaft in the direction of the arrow see Fig. 7. The arm 54 at the inner
end of the rock-shaft 53 has attached to it a cord 55 which is extended upwards
through a hole in the usual guide-board 56 thence through one of the usual needles
and through a hole in one of the usual trap boards, above which it is attached to a top
board P the said cord extended through the trap board having a cord to be trapped as
usual through the operation of the jacquard cards on the needles so that the cord may
be lifted whenever desired. The arm 54 referred to, at its inner end see Fig. 7 and 7 a
has a bevel finger 57 and a lug 58 the latter serving merely as a stop for the rock-
shaft 58 when turned in the direction of the arrow referred to. The bracket or
stand pin which the rock shaft 53 has its bearing is provided with a stud 59 upon
which is pivoted a locking device 60 having an arm which co-operates with the bevel
finger 57 of the arm 54 the said locking device having a cord 95 which co-operates in
like manner with the trap board 82. Referring to Figs. 1, 1", and 4, the crank
shaft A¹ just behind the toothed gear A2 is provided with a bevel gear 61 which
engages a bevel gear 62 see dotted lines Fig. 1, on and rotates a shaft C3 having at
its upper end a small bevel gear 64, engaging a bevel gear 65 (see Fig. 1) fast to one
end of the main shaft 66 of the jacquard mechanism, the said shaft having fast to it
near each end a series of cams, not shown, which in practice at each rotation of the
said shaft act in usual manner in succession upon a series of levers connected by rods
with the usual journals not shown which act in usual manner upon the knots of the
jacquard harness to lift the same or permit the harness to drop in the formation of
sheds in the warp for the passage of the shuttle. The jacquard or tail cords are
attached in usual manner to harness cords a number of which, attached to each tail
cord, pass through holes in the usual journals, not shown, the said journals in their
rising movement acting upon knots in the harness cords and forming the shed, the
trap-boards and journals operating in usual manner to form the sheds for the ingrain
figures.
These journals and their actuating devices being old and common in looms usually
employed for weaving ingrain carpets are not herein shown. The main shaft. 66 of
the jacquard has attached to it a toothed gear 67 see Fig. 2, which engages and
rotates a toothed pinion 68 mounted on a suitable stud and having a crank or wrist 69
upon which is fitted a connecting rod 70 the upper end of which in turn engages a
pin 71, of a crank 72 on the shaft 73 the said shaft having attached to it two like
cross arms 74 which-by links 75 are joined to like slides 76 carrying the usual trap-
boards 81, 82. The jacquard cords not shown, will in practice be supported from the
top board p and thence extend down through a hole in one of the trap boards 81 or 82,
thence through an eye of a jacquard needle of usual construction, the series of needles
arranged in usual manner being actuated by a series of jacquard cards St carried by
a lantern or other wheel 85 rotated in usual manner, all the said devices acting in
usual manner to move the warps to form sheds, herein the said lantern wheel is shown
as mounted in boxes at the ends of slide rods 86 actuated by arms 87 attached to a
rockshaft 88 having an arm 89 see Fig. 3*, extended backward from the loom and
attached by links 90 to one end of a lever 91 which is moved by a cam 92 see Fig. 3ª,
secured to the main shaft 66 of the jacquard, said cam acting upon a roller or other
stud projecting from the side of the said arm. A pawl 93 engaging usual studs at

page_text: the end of the lantern wheel and rotates the same intermittingly. Instead of the
particular jacquard mechanism herein shown we may employ any other usual or well
known mechanism.
If the ratchet wheel 37 see Fig. 3 and the detail Fig. 7° is to be engaged and
moved step by step by the pawl 46 then the cord 51 and its devices would be
unnecessary.
When the pawl 46 is to engage the ratchet wheel 37 to which the said cam 38
attached to the sleeve carrying the said ratchet and at such time the arms 52 occupy
their lowest position as in Figs. 2 a 3 a and 7. When the pawl is to be lifted a jacquard
card through a jacquard needle moves the cord 55 lifts the arm 52, turns the rock
shaft 53 and lifts the arm 52 and by the cord 51 the pawl 46 is lifted. As the arm 54
is lifted as described the finger 57 passes from the position Fig. 7 to the position
Fig. 7 a and as soon as the said finger passes below the short arm of the locking
device 60 permitting the spring 96 to move the tacking device into the position
Fig. 7 the locking device holding the arm 54 elevated and the pawl 46 out of the
range of movement of the ratchet wheel.
With the parts in the position described, see Fig. 7 a to permit the pawl 46 to be
lowered to engage the ratchet wheel, it is only necessary to lift the arm 60 in the
direction of the arm Fig. 7 a until the short arm thereof passes beyond the end of the
finger 57, the locking device sliding off the end of the said finger leaving the weighted
ends of the arms 52 and 56 to descend until the finger 58 meets the stop 59.
The Specification of Letters Patent No. 3655 of 1883 before referred to shows
two warp beams, but in this present loom but one warp beam is shown. Herein
the means for moving the warp beam to let off the warps and the whip roll over
which the warp passes from the warp beam to the eyes of the harness cords, are
all substantially as in the said patent, so need not be herein described.
lay, at its rear side near the ends of the reed, is provided with like brackets m
which receive a rock shaft m¹ to the ends of which outside the said brackets are
attached two like feelers m².
The
The arm of the feeler m² near the right hand of the loom, see Fig. 1, has
attached to it a rod m³ which is extended down and joined to a lever m³ pivoted
at m³, the rear end of the said lever being acted upon by a double throw cam mⓇ
shown by dotted lines Fig. 1 secured to the cam shaft A³ the said cam, lever,
and rod, serving to raise and lower the feeler positively at the proper time during
each beat of the lay to feel for the filling. The brackets m referred to have each
a suitable stud upon which is pivoted a like grid m². Each grid m' see Fig. 8,
is connected by a link m8 shown by dotted lines, with an arm m³ of a dagger
shaft m having suitable bearings m2 at the underside of the lay and provided
with a dagger m³ see Fig. 9, the said dagger shaft having, see Fig. 11, an
arın m which is acted upon by a spring m15 attached to the under side of the
lathe, the said spring normally keeping the dagger with its forward end depressed
and the grid elevated so that whenever the filling is properly laid across the grid
end and the filling fork descends upon the filling the grid will be depressed and
through the link m turn the dagger shaft and lift the dagger m¹³ so that it will
not effect the stopping of the loom as it would otherwise do. The dagger shaft m¹0
see Fig. 12 has secured to it a stop me which limits the movement to the said
rock shaft under the action of the spring m¹.
Should the filling be absent or at fault and the grid be not depressed by the
filling fork m², then the dagger m¹³ see Fig. 9, attached to the dagger shaft, will meet
a dog m pivoted at m¹8 upon a slide bar m¹ and will move the said slide bar
longitudinally in a guide m20 supported from the inner side of the breast bean, and
will cause the outer end of the said slide bar to strike a lever m²¹ mounted upon a
stud at the lower side of the breast beam and will turn the said lever so as to act upon
a lug m² see Fig. 5, connected to the slide rod s common to the said patent moving
it longitudinally to the right in Fig. 1 to effect the release of the shipper lever A
from its holding notch n see Fig. 4 of the plate n' wherein the said lever is shown as
released. As the dog m¹ engaged by the dagger as in Fig. 9, is moved in the

page_text: direction of the arrow, an inclined part of the dog below its fulcrum acts upon a
roll n² supported by the guide m2, causing the dog to he tipped on its centre thus
releasing it from the dagger m¹³ but not until after the shipper lever A has been
released from the notch n in the usual holding plate n¹. The slide bar m² referred to
see Fig. 4, has attached to it a finger n which in the forward movement of the slide
bar m strikes the end of the bunter operating lever n³ pivoted at n at the under side
of the breast beam, causing a finger n see Fig. 10, at the opposite end of the said
lever, to strike against the outer beveled end of the bunter lever n thus pivoted at n°
on a yoke 10 thus lifting the inner notched end 8x of the said lever and placing it
in the line of approach of the bunter or stop n see Fig. 10, projecting from a block no
secured to the under side of the lay, the said projection entering the notch in the inner
end of the bunter lever before the lay in its forward movement, (the shipper lever A³
having been released,) brings the reed of the lay to the fell thus completely stopping
the lay during that forward movement of it in which occurs the fault in the filling.
As soon as the shipper lever A is released and before the bunter or stop n comes into
operation to stop the forward movement of the lay, the hub K or the friction pulley
has been operated to withdraw the wedge K20 thus releasing the strap K" separate its
parts, leaving the pulley K₁ free to move with the belt, the latter running with the
loose part of the friction pulley.
The loop shaped stand no on which the bunter lever is pivoted is free to slide to a
limited extent upon a bolt or pin p held in suitable ears or bearings pl, a block of
rubber, or other suitable spring, as p³ being applied between one of the arms as 102
of the slide block and one of the ears 203 the rubber or other spring p³ avoiding
injurious shock and by its rebound giving a slight recoil to the lay to throw it back
into such position as to enable the operator to readily reach the broken or misplaced
filling.
こ
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a loom the combination with a lay and breast beam, of a filling stop
mechanism, substantially as described, containing a slide bar, and a projection, a
lever moved by the slide bar, a shipper handle, and a rod moved by the lever to
release the shipper handle, a lever moved by the projection, a bunter pivoted at the
underside of the lay and operated by the said projection, and a projection carried by
the lay, the said parts being constructed and arranged substantially in the manner
described, whereby the shipper lever will be released and the bunter elevated to
arrest the forward movement of the lay, all during one and the same forward beat of
the lay.
2. The combination with the lay, breast-bean, and a friction clutch pulley, to
impart motion to the main cam shaft of the loom, of a filling stop mechanism
substantially as described containing a slide-bar, a lever moved thereby a rod moved
by the said lever to release the shipper handle, and a rod actuated by the shipper
handle and having a projection to actuate a hub forming part of the friction driving
clutch pulley, whereby the band receiving rim of the clutch pulley is freed from the
shaft driving the loom during that forward motion of the lay in which the fault in the
filling enables the dagger to fall and actuate the slide bar of the said stop-mechanism,
substantially as described.
3. The combination with the shuttle-box pattern surface and actuating devices
therefor, of a controlling mechanism, substantially as described, under the control of
a jacquard whereby the hub forming part of the mechanism for driving the shuttle-
box pattern surface from a moving part of the loom may be automatically shifted at
the proper time to move the pattern surface backwards and forwards for a short
distance for "shot-about" weaving, substantially as described.
4. In an organized loom for the production of Ingrain carpet, a shifting shuttle
box mechanism, substantially as described, having main and auxiliary levers at the
same side of the loom and having connections to operate the shuttle boxes at opposite
C

page_text: sides of the loom; means to rotate the said pattern surface or chain in one or the
other direction; controlling mechanism substantially as described to automatically
control the direction of rotation of the mechanism for rotating the pattern surface
for the shuttle-box mechanism; a jacquard mechanism to control the formation of the
sheds a shipper lever to effect the release of the loom from the power driving it, and
a stop-mechanism, substantially as described, actuated by fault in the filling to release
the shipper handle, substantially as described.
5. In a loom, a pair of fluted rolls to take the woven carpet or fabric from the
breast-beam, combined with a shaft, a sleeve thereon having a worm, and a locking
device to enable the worm to be driven by the said shaft or to be released from the
shaft and turned by hand to rotate the said rolls in one or the other directions,
substantially as described.
6. In a loom, a pair of fluted rolls to take the woven fabric or carpet from the
breast-beam, one of the said rolls having end and intermediate bearings, the said rolls
being provided with gears whereby they may be rotated one from the other
substantially as described.
7. In a loom, a pair of fluted rolls to take away the woven fabric or carpet
from the breast-beam, gearing to connect the said rolls, a worm toothed gear secured
to one of the said rolls, the said gear having as many teeth as there are picks in the
fabric or carpet being woven, combined with a worm to engage said worm gear, a
shaft to rotate the said worm, adjustable bearings for the said shaft, the adjustment of
the bearings enabling gears of different sizes to be employed according to the
character of the fabric being woven, substantially as described.
8. The lay, the feelers, the shaft to which they are connected, a rod connected to an
arm of the said shaft, a lever connected to the said rod, a cam to actuate said pivoted
lever, the pivoted grids, links to connect them with arms of a dagger shaft, a dagger
thereon, a spring to operate the dagger shaft, a shipper-handle, a rod operatively
connected therewith, and a lever to which the rod is attached, combined with a slide-
bar, a guide for it, and a dog pivoted on the slide-bar, said part being combined to
operate, substantially as described.
9. The combination in a loom of a ratchet, and pawl to move it, a rock-shaft having
weighted arms, one of which has a finger and a stop, a cord to connect one of the
said arms with the said pawls, a second cord to connect the other of the said arms
with a trap-board of a jacquard mechanism, combined with a locking-device to act
upon a finger of one of the arms of the rock-shaft to keep the pawl elevated from the
ratchet to be moved by it, and a cord connecting the said locking-device with a trap
hoard of the jacquard mechanism, substantially as described.
10. The combination with the driving shaft of a loom, of a loose pulley having an
annular inner flange, a sleeve capable of a longitudinal movement on said shaft and
provided with a pivoted wedge, and a strap carrier secured to the shaft and having a
strap nearly encircling the said flange, and a pair of levers pivoted to the said strap
carrier and having jaws engaging lugs and projections at the end of the strap whereby
the strap may be made to grasp the annular flange of the loose pulley to ensure the
rotation of the said shaft, as described.
