page_text: I, PHILIP MIDDLETON JUSTICE of 55 and 56 Chancery Lane in the County of
Middlesex Fellow of the Institute of Patent- Agents do hereby declare the nature
of this invention (a communication from abroad by William Weaver of Westport,
Fairfield County in the State of Connecticut, United States of America, Manu-
facturer) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The invention consists in certain improvements in the method and means of
weaving, to improve the manufacture of textile fabrics, to lay a doubled weft across
the warp at each traverse of the thread carrier and prior to each beat; and in means
for imparting a positive traversing motion to the thread carrier, and in the various
details of construction of the loom hereinafter set forth.

In Figs. 1 and 2 parallel lines a represent the warp threads; A, represents the
breast beam; B, the lathe; C, the reeds, and the line to which the wefts have
been beaten up by the lathe. These parts may be constructed as in ordinary
looms and the warps are operated by the heddles in the ordinary manner.
The wefts or filling threads instead of being carried by the shuttle as usual are
conducted from bobbins X, one or more adjacent to each side of the warp, and
'extending through an eye z, upon the lathe, or otherwise suitably guided so as
to be seized by a carrier that traverses the lathe in the manner of an ordinary
shuttle.
As shown and more fully described hereinafter, the carrier D, is provided at
each end with a hook or catch e, and receives a positive motion, and is so operated
that as it approaches either end of the lathe its hook will catch the adjacent
thread y, and then as it moves away from that end will draw it in the form of a
loop, or doubled completely across the warp, and will then be detached from the
weft loop as the latter is beaten up by the forward motion of the reed.
As the carrier brings one loop of thread y, to one edge of the warp its opposite
or outside hook engages with the other thread y, adjacent to such edge, and after
the shed is again opened this last mentioned thread y, is also drawn in the form of
a loop, or doubled to the opposite edge of the warp and is then released and beaten.
up as the first thread y, is again seized by the outside hook of the carrier.
Two important results are obtained by this mode of operation, first, the weft is
laid doubled in the shed, which for some purposes results in a desirable fabric, and
Becondly the weft is laid doubled in the warp at each traverse of the carrier, so
that there is no loss of time as results from a return movement without the laying
of the thread.
So far as this mode of weaving is concerned the construction and mode of
operating the carrier are immaterial provided it will carry the two independent
doubled weft threads alternately from opposite sides across the warp.
For general purposes is is sufficient to draw a loop close to the edge warp and
there release it without any further securing of the same than results from the
thread being beaten up and the shed closed, thus forming a sufficient selvedge in
most instances, when, however, it is necessary to secure the loop absolutely this
can be done by means of a shuttle thread w, Fig. 6, carried by a shuttle e¹,
traversing a race f, parallel and adjacent to the edge warp and operated so as to
interlock the shuttle thread with the loop of thread y. The shuttle e¹ may be
driven by mechanism similar to that driving the carrier D, or by any other
suitable well known means.
I prefer, however, to form the selvedge by interlocking the successive loops of
weft thread by means of a latch needle g, Figs. 1 and 2 carried by a needle bar H,
sliding in bearings d, arranged upon the breast beam close to the edge warp,
as shown.
Each latch needle bar is operated through the medium of suitable mechanism
arranged to move the needle bar back and forth, so as first to pass the needle
through the loop 2 of the thread y, as soon as it is formed, as shown in Fig. 3,

page_text: and to retain it upon the shank, and then seize the next loop 3, as soon as it is
formed, as shown in Fig. 4, and then move backward and draw the loop 3, through
the loop 2, as shown in Fig. 5, after which its forward movement will carry the
loop 3, upon its shank to the position formerly occupied by the loop 2.
It will be noted that the carrier after seizing the loop and doubling it in the
warp, passes wholly beyond the side of the warp, and the warp operating appliances
are set to permit the weft to be beaten up before the return movement of the
carrier with the weft from the opposite side, each doubled weft is thus beaten up
and secured by the closing of the shed.
The carrier may be driven from below the warp by means of a reciprocating
cradle in which it lies loosely in the same manner as shuttles have heretofore.been
driven, but this is open to the objections of friction upon the warps and lack of
absolute positiveness of motion.
To overcome these objections the shuttle or carrier driving appliances which will
be now described are employed.
The lathe is provided with a channel or race within which is reciprocated a
block or carriage L, carrying a wheel M, having a central hub and thin radial
projecting blades or teeth q, each of which has a notch i, in each edge, and into
the notches upon each side of the wheel extend curved plates m, secured to the
carriage in such position that a portion of the wheel projects above the upper face
of the carriage, with the teeth or blades thereof above the upper face of the lathe.
The curved blades m, hold the wheel positively in a fixed position in respect to
the carriage but permit it to be revolved freely upon said curved blades as bearings,
a rotary motion being imparted from a stationary rack M², over which the carriage
slides, through the medium of a pinion O, carried by the carriage and engaging
both with the rack and wheel, or by means of a stationary cord h, (Figs. 11
and 17) secured at its opposite ends to the lathe and passing one or more times
around a hub or drum h¹, of the wheel to rotate the latter as the carriage recipro-
cates; or by means of the pinion O, meshing directly with a pinion arranged on
the side of the wheel M, Fig. 12.
In any case the arrangement is such that upon drawing the carriage L, towards
either end of the lathe, the wheel M, will be revolved in a reversed direction to
the travel of the carriage and at such a speed that its blades will pass through the.
warps lying upon the face of the plate without drawing or imparting any lateral
deflection thereto.
The carrier D, is positively connected to the blades of the wheel M, at a point
above the plane of the warps by curved plates m³, which extend from the carrier
into the notches i, in the sides of the blades q.
This connection is a positive one, rendering the carrier undetachable from the
wheel, yet permitting the latter to revolve freely, so that as the wheel is moved
from end to end of the lathe the carrier is conducted by it with a positive motion
above the plane of the warp threads, which enter the spaces between the teeth q,
and pass between the hub of the wheel and the carrier without being deflected
and without any friction or wear.
The lower edge of the carrier D, may be set so close to the face of the lathe that
the carrier will practically occupy a horizontal position, I prefer, however, to set
the carrier a short distance above the said face, the result being that the forward
end of the carrier is always tilted down towards said face, so that the outer hook 6,
that approaches either thread y, will first pass beneath the latter and will then be
lifted to catch the same as soon as the carrier is tilted as the carriage begins to be
drawn in the opposite direction, the hook upon the inner end being thus at the
same time depressed and being thereby withdrawn from the loop of thread y,
which has just been carried between the warps, and which is held by the warps
stationary so that the hook can be drawn therefrom.
By means of the curved plates fitting the notches in the teeth of the wheel M, a
positive connection between the wheel and carrier is secured, which connection
however permits absolute freedom of revolution of the wheel with .comparatively,

page_text: little friction, so that the carrier is driven positively by connections from below,
completely through the shed without the connection with the driving parts
interfering with the beating up of the weft.
It is not necessary that the grooves for the reception of the curved connecting
plates m, m³, shall be in the sides of the blades or teeth q, they may be in the ends
thereof, either central or otherwise as shown in Figs. 9, 10 and 17 and adapted to
receive curved plates or ribs m, ml; that are T shaped or dove-tailed in cross
section, the positive connection but the free rotation of the wheel being secured as
before. The pinions O, may be arranged horizontally as shown in Fig. 17.
Instead of a hook at the end of the carrier the latter may be provided with jaws
(Fig. 11) which open to receive the thread y, when brought against it, and then
close positively, or spring together, one of said jaws being brought against a
suitable device for opening it as the carrier reaches the limit of its movement in
either direction. Thus there may be a spring s³; bearing upon a pivoted jaw P,
and a fixed jaw P¹, each having a shouldered horizontal arm as shown in Fig. 11,
and an arm t, of the jaw P, may be arranged to strike a stud. n, as the carrier
reaches the limit of its movement, thus opening the jaws and releasing the thread.
It will be obvious that where it is desired to employ a shuttle, the latter may
take the place of the carrier being connected to the wheel M, by one or more
curved bearings fitting notches in the said wheel in the same manner as the carrier
is attached.
Although reference has been made to the driving connection with the shuttle or
carrier as being below the shuttle, it will be evident that an inversion of this
arrangement, the driver being above and the shuttle suspended would be attended
with like results.
It will be obvious that there may be two or more filling or weft threads on each.
side of the loom, as shown in Fig. 6, so that the carrier may seize both of them,
(said Fig. showing a bobbin X, carrying one thread and a shuttle el carrying the
other.)
The block carriage or part L, to which a reciprocating motion is to be given.
as already stated; may be any part or object used in mechanism of various kinds,
and may reciprocate within a race as stated, or be guided by any suitable support
or supports..
The block may be reciprocated by different appliances. As shown in Fig. 7, two
draft cords 8, 81, are connected to the ends of the block and conducted in opposite
directions around guide pulleys 12, 13, and wound in opposite directions around a
grooved wheel p, which is revolved first in one direction and then in the other
by the winding and unwinding of the cord v, upon a drum T, upon the shaft of
the pulley, which cord passes around guide pulleys and is connected to a lever Q,
vibrated by means of a cam or wiper upon one of the shafts of the machine.
Another good arrangement for imparting motion back and forth to the block is
shown in Figs. 13 to 20, in which is shown one or more continuous bands, belts or
chains S, which extend upon opposite sides of the block L, and round two or more
band wheels or pulleys 12, 13, the endless band being provided with one or more
bearings adapted to engage with shoulders upon the block; or with brackets or
projections b, extending therefrom:
In the drawing the band is provided with a single bearing c, consisting of a bar
riveted to and projecting beyond the edges of the band, so as to make contact with
the ends of two brackets b, b, projecting from each side of the block.
As the pulleys revolve in either direction the block remains stationary until the
bearing c, is brought in contact with the bearings b, at one side, after which the
block and the band will travel together until the bearing c, passes froin contact
with the bearing b, when the block will cease its movement in that direction and
it will be carried in the opposite direction as the bearing c is brought by the travel
of the band into contact with the brackets at the opposite side of the block.
Different means may be employed for removing the bearing c, from contact with
the shoulder or bearing upon the block, for instance the two may be in frictional

page_text: contact so that they will travel together until the block comes in contact with a
positive stop, when the bearing will move away from the bracket, it is preferred,
however, to disconnect the parts by carrying the bearing out of position, so as to
pass beyond the bracket. One means of effecting this is shown in the drawing,
and consists in combining with the parts already described four guides d', d², f¹, f
having grooves e³, which for the greater portion of their length are parallel with
the straight sides of the belt, the guides being arranged above and below the bar c,
the ends of which extend into the grooves as shown in Fig. 15, so that as the bar
moves with the belt it will travel in a straight course and in contact with the
brackets b, but the ends of the guide grooves are curved outward as shown in
Fig. 14, so that as the block L, nears the end of its course, the bar c, will be carried
outward and away from the brackets b, the belt swinging outward to accomodate
this movement, after which the bar will travel with the belt until it is brought in
contact with the brackets at the opposite side, and the above described movements
may be repeated.
By this means a positive reciprocating movement is imparted to the block from
the continuous rotation of the pulleys 12, 13, one of which may be secured to the
driving shaft g¹.
To ensure the entrance of the bearing bar c, into each groove e³, as the bar
approaches the guide, the said groove is made with an expanded or widened mouth,
as shown in plan Fig. 14.
Where the endless band mechanism is employed in connection with looms, it is
necessary to reciprocate the carriage or block upon a swinging support, as shown
in Fig. 18, where the block L, is reciprocated upon a frame D¹, swinging upon a
pivot or shaft h².
This may be effected by mounting the driving shaft g¹ in bearings at one side or
end of the frame D¹, and providing it with a bevel gear j, engaging with a bevel
gear, upon the pivoted shaft h³, so that the rotation of the shaft h², will rotate
the shaft g, without interference or preventing the swinging of the frame upon its
pivot.
The pulleys 12, 13, may be mounted upon any suitable bearings so arranged
that the parallel sides of the belt will enclose the path of the block L, as shown,
the brackets k, which support the shafts of the pulleys are secured to the opposite
ends of a long narrow box I, which supports the bed, or the lower side of which
constitutes the bed, and also supports the guides d', d, f¹, f
The guides for the bearing or bar c, may consist of ribs n, instead of grooves, as
shown in Figs. 19 and 20, in which case the bar c, has notches u; in the ends to
receive the ribs, and these notches are widened towards the end faces of the bar, so
as to insure the guiding of the bar on to the ribs.
In some cases the bar instead of being secured at one side to the band or chain
may be introduced in the latter as one of the connecting links, as shown in Fig. 20.
Having described the mode and means of operating the wefts, I will now proceed
to describe the loom embodying the devices and mode of manufacture heretofore
described, reference being had to Figs. 21 to 27 of the drawings.
The frame A, of the loom is constructed to support the parts hereinafter
described, the lathe B, is pivoted and the carrier or shuttle is driven along the race
as before set forth.
In the construction shown the loom is intended especially to operate as a terry
loom, and I employ devices which operate automatically to vary the beat of the
lathe.
For this purpose the arms or pitmen a, connected to the crank shaft C, which
vibrates the lathe are jointed at their forward ends to slides D, adapted to guides D³,
at the back of the lathe, the throwing up of the slides preventing the beating up
of the lathe, which, however, results when the sides are lowered.
The upward movement of the slides is preferably caused by springs b, acting
upon levers E, pivoted to the standards E, and connected by rods c, to levers F,
pivoted at their rear ends to the frame and connected by rods d, to the slides D.
J

page_text: The downward movement of the slides is effected by means of a wiper g, upon à
shaft G, geared to the driving shaft H.
To prevent the constant reciprocation of the slides, resulting from the continuous
rotation of the shaft G, detents are combined with the levers F, for the purpose of
holding said levers in their lowest position, and which detents are under the
control of automatically operating appliances as pattern wheels or chains, start and
stop motions, and so forth.
These detents may be of any suitable construction or arrangement, as any catchi
thrown into position above the levers F, after they have reached their lowest
point, will suffice to detain them, while various automatic controlling devices may
be used for moving the detents at proper regular or irregular intervals.
As shown in Figs. 26 and 27 each detent consists of an arm H2, having a lower
shoulder x, and hung to a shaft H¹, turning in bearings on the side bars of the
frame, the. two shafts being connected so that the arms will be simultaneously
thrown inward or outward by means of the cross bar H³, jointed to ears d, fastened
to the shafts H¹.
The automatic rocking of the shafts H, to throw the catch arms H³, away from
the levers F is effected by a spring D³, secured to the frame of the machine and to
a pin d³, projecting from the shaft H', and the reverse movement of the shaft H',
to bring the arms H2, into the paths of the levers F, is effected by a pattern
wheel I, meshing with a pinion J, on the end of.the shaft of the drum K, the said
pattern wheel being provided with one or more lugs f, arranged to strike a hanging
lever L, which bears at the lower end against an arm or hand lever L¹ (Fig. 23)
upon one of the shafts H¹.
By varying the relative diameters of the gears I, J, each revolution of the take-
up roller will cause more or less than one revolution of the gear I, and by providing
the latter with a series of openings, pins f, may be inserted therein at proper
intervals. By these means the detent arms H³ may be thrown in and out at
any desired intervals and the levers F, and slides D, connected thereto, will be
correspondingly caught and released so as to secure any desired variation in the
beats.
As the arms H2, might be thrown inward while the levers F, are in their upward
positions, the parts of the loom might be injured by the descent of the levers, if
the arms were connected positively to the shafts H.
To prevent this a yielding of the arms H2, is provided for should pressure be
brought against them from the inside. Thus the arms H2, may be hung loosely to
the shafts H, and may be provided with pins h, held in contact with lugs i, on
the arms d (Fig. 27) by means of springs ¹, so that normally the rocking of the
shafts H', will vibrate the arms, but the latter may swing independently upon the
shafts should the levers F, be brought downward against them.
+
The take-up beam Fig. 24, is rocked from a vibrating lever M, carrying a pawl j,
which engages with the teeth of the ratchet M¹, on a shaft carrying a pinion
gearing with the wheel D7, on the take-up beam, as shown; the lever M, being
vibrated from a lever M2, to which it is connected by a rod M³, the lever M², being
pivoted at its lower end and vibrated by means of a cam M*, on the shaft G, which
cam has a groove.at its inner face receiving a pin on the lever M³, as shown in
dotted lines Fig. 24.
There are two let-off motions which consist each of two lower rollers L, 1, (Fig. 22)
upon which an upper roller is caused to bear by spring pressure, the three rollers
being geared to turn together and a large cog wheel 12, (Fig. 24) connecting the
two motions, and the warps from the two beams N, N', pass therefrom to the
different rollers, as shown. The gears are so proportioned that the upper or terry
warp feeds faster than the ground warp as usual.
A ratchet wheel O, is secured to the shaft of one of the rollers and is operated
by a vibrating lever P, hung upon the journal of the ratchet and carrying a
pawl m, which engages with the teeth of the ratchet, and the lever P, is connected
to the lever M2, by a connecting rod P¹.

page_text: It will be seen that the let-off motion and the take-up motion are connected and
operated by the same lever M2, whereby unison may be secured, but any variation
is obtainable by varying the connection of the rod M³, with the lever M². This
may be done by providing the lever M, with a series of openings permitting the
connecting pin m¹, to be connected at different points.
The heddle motion consists of the usual levers Q, and bars Q¹, suspended at the
outer ends thereto, guided in the frame R, and each depressed when thrown inward
by a reciprocating carrier Q³, the cross bar p¹, of which upon its downward motion
engages with the shoulders of said bars. These shoulders are formed by spring
rods q, attached at the lower ends to the inner sides of the bars bent outward and
then inward to form the shoulders r, so that on the upward movement of the
bar p¹, the spring rods will yield and permit the bar to pass, and will then swing
outward so that the bar may make contact with the shoulders on its descent.
The lower ends of the bars Q¹, are thrown outward by means of springs &
connecting the upper ends of the bars with a cross bar s¹, on the frame, so, that the
carrier Q, only makes its contact with and carries down such bars as are thrown
inward by the pattern motion.
The pattern motion in the present instance consists of a series of cylinders Z
provided with lugs and carried by a frame S, turning upon or with a shaft t,
having its bearings in brackets t¹, the revolution of the said frame bringing either
cylinder to operate upon the bars as may be desired, the cylinders each carrying a.
pinion u, which gears with a central pinion u¹, the revolution of which will turn
all the cylinders while the frame occupies a stationary position.
The driving pinion u³, is connected to be turned by a ratchet wheel T, moved
with a step by step motion by the vibration of a lever T¹, carrying a pawl V,
which engages with the teeth of the ratchet, and this lever is connected by a rod 3
(Fig. 24) to and reciprocated by a lever U, to which a vibrating motion is imparted
by a cam U on a shaft C, Fig. 22.
The lever U is connected directly to the carrier Q, which is thus elevated at
the time the upward movement of the lever U, brings the pawl V, forward upon
the ratchet and rotates the cylinders, so that the latter are adjusted before the
downward movement of the lever U, and of the cross bar p².
The frame S, may be turned to bring either cylinder opposite the bars Q¹, the
gear connections insuring the operation of all. The means shown for rocking
the frame consist of a shaft W, and band lever W₁, Fig. 24, and connecting
arms w, w¹.
The shaft W, has a slight longitudinal motion in a plate Y; and is drawn toward
the latter by a spring 5, so as to normally keep a lug 6, on the lever W¹, in a hole
in the plate, thus holding the frame S, in any position to which it is set, but
permitting adjustment on pulling out the shaft by means of the lever W₁
A collar 7 (Fig. 24) turns with but slides on the shaft t, of the frame S, and is
pressed by a spring 9, against the bracket t¹, to create sufficient friction to prevent
the jolting of the frame S, out of place, and hold it when the lever T' is moved.
By means of the adjustable frame carrying a series of driven toothed cylinders,
the simple part revolution of the frame will enable the operator to at once make a
total change in the character of the fabric produced by the loom.
It will be obvious that any desired number of cylinders may be carried by the
frame, and that the latter may be hung and adjusted in any suitable manner so as
to permit any one of the cylinders to be brought into operation.
Instead of elevating the slides D, through the medium of the levers E, rods c,
and springs b, as described, to vary the beat of the lathe, it will be obvious that
other means may also be employed with like effect, such for instance as by spiral
springs, (see dotted lines Fig. 22,) encircling the rode d', and supported at their
lower ends by suitable brackets on the frame of the loom and through which the
rods slide, while the upper ends of the springs bear against collars 8. By this
arrangement when the slides are drawn downward by the action of the wiper g,

page_text: the springs d, are compressed and as soon as the slides are again free to be
elevated they are raised by the expansion of gaid springs.
