Improvements in and connected with Looms for Weaving.
I, WILLIAM RODGER, of 3 Abbotsford Road, Galashiels, in the County of
Selkirk, North Britain, Manufacturer, do hereby declare the nature of this
invention to be as follows, that is to say :-
My said invention relates to the mode of, and mechanism for, inserting the
weft in looms for weaving, and has for its object to dispense with the placing
of pirns, cops, or bobbins, in the shuttle or wefting instrument, and to substitute
novel and advantageous devices by means of which wefts can be drawn off rolls,
bobbins, or cops, at both sides of the loom. With my improved arrangements
I avoid the waste of labor and time in stopping the loom to change the pirns
wefting instrument
in the shuttles as ordinarily practised, whilst only one shuttle or
is required even when two or more different wefts are used in any order or
according to any pattern.
In carrying out my invention I employ a shuttle or wefting instrument shaped
for being picked or propelled across the loom by the ordinary or any suitable
picking mechanism, and fitted at one or at each end with a pair of gripping
fingers or jaws. The weft is suitably guided or presented so as to be taken
hold of by the gripping fingers of the shuttle, and to be carried through the shed
when the shuttle is picked. A tension or holding-back device is applied to cause
the weft to be distended and free from snarles when laid in the shed, and before
the length is cut off. On reaching the further selvedge the shuttle encounters, or
is acted on by, parts which cause its gripping fingers to open and release the weft
end then held by them; and on its return the shuttle, either with the same gripping
fingers or with the pair at its other end takes hold of weft presented to it at that
side of the loom and carries it through the next shed. The weft lengths are cut off
from the rolls, bobbins or cops by suitable cutters after each has been laid, any.
free ends left by the cutting operation being wound back on the rolls, bobbins,
or cops, or otherwise disposed of in a manner to be properly presented again
to the shuttle.
It may be arranged for the shuttle to simultaneously lay two or more wefts in
the same shed, or to lay a loop of weft in the shed such loop being caught and held
by a pin or other appliance at the further selvedge.
When differently colored or otherwise different wefts are employed the instru-
ments which present or guide their ends to the shuttle or wefting instrument are
moved as required by means of any suitable pattern mechanism.

I, WILLIAM RODGER, of 3, Abbotsford Road, Galashiels, in the County of
Selkirk, North Britain, Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, that is to say :-
My said invention relates to the mode of, and mechanism for inserting the weft
in looms for weaving, and has for its object to dispense with the placing of pirns,
cops, or bobbins, in the shuttle or wefting instrument, and to substitute novel and
advantageous devices by means of which weft can be drawn off rolls, bobbins, or
cops at both sides of the loom.
With my improved arrangements I avoid the
waste of labor and time in stopping the loom to change the pirns in the shuttles as
ordinarily practised, whilst only one shuttle or wefting instrument is required even
when two or more different wefts are used in any order or according to any
pattern.
In carrying out my invention I employ a shuttle or wefting instrument shaped
for being picked or propelled across the loom by the ordinary or any suitable
picking mechanism, and fitted at one or at each end with gripping fingers or jaws.
The weft is suitably guided or presented so as to be taken hold of by the gripping
fingers of the shuttle and to be carried through the shed when the shuttle is picked.
On the shuttle approaching the further shuttle box the weft is released from the
gripping fingers; and the shuttle either with the same gripping fingers, or,
preferably, with those at its other end takes hold of the weft presented to it
at that side of the loom, and carries it through the next shed. The weft threads
are cut off from the rolls, bobbins, or caps by suitable cutters after each has been
laid. Or it may be arranged for the shuttle to simultaneously lay two or more
wefts in the same shed; or to lay a loop of weft either in one shed or with parts
in separate sheds.
When differently colored or otherwise different wefts are employed the
instruments which present or guide their ends to the shuttle or wefting instrument
are moved as required by means of any suitable pattern mechanism.
And in order that ny said invention and the manner of performing the same
may be properly understood I hereunto append four sheets of explanatory drawings
to be hereinafter referred to and representing various modifications of devices to be
employed in carrying out my improvements.
Figures, 1, and 2, on Sheet, 1, of the drawings are a plan and a sectional front
elevation showing part of a loom lathe and part of the breast beam of the loom
together with devices used in one modification of my improved apparatus.
Figures, 3, 4, and 5, are transverse vertical sections corresponding to parts of
Figures, 1, and 2; and Figures, 6, and 7, are a sectional plan and sectional
elevation of other parts.
Figures, 8, and 9, on Sheet, 2, are a plan and a sectional front elevation of part
of a loom lathe and other parts as made with a second modification of
my improved
apparatus and Figures, 10, 11, and 12, are transverse vertical sections corre-
sponding to parts of Figures, 8, and 9.
;
Figures, 13, to 18, on Sheet, 3, are enlarged views of parts shown on Sheets, 1,
and 2, and Figures 19 to 25, are views of other modifications of certain details.
Figures 24, to 31, on Sheet, 4, are views of modifications of shuttles or wefting
instruments.
In these drawings the same reference letters and numerals are used to mark the:
same or like parts wherever they are repeated.

page_text: In the modification partly represented in Figures, 1, and 2, the weft is laid in
single lengths both ends of which are cut. About half of the reed, A, and other
parts is shown in Figures, 1, and 2, the other half being similar but with several
parts reversed in position so that like parts are oppositely equi-distant from the
centre. The reed, A, is as usual held between the batten, A 1, the top of which is
the race (hereinafter referred to as also, A 1) and the rail, A 2, the batten and the
rail being fixed at their ends to the lathe swords of one of which a small part, A 3,
is seen in Figure, 2. In Figures, 1, and 2, are also shown parts of the breast bean, B,
and one side frame, B 1. At the side there is a shuttle box, A 4, the inside bottom of
which forms a continuation of the race, A 1; and at the outer end of the shuttle box
there is fixed a pillar or bracket, A. 5, having fixed in it a horizontal spindle, A 6,
directed inwards nearly in line with the reed, A. The wefting yarn or thread, C,
which is wound in the form of a slightly coned roll, C 1, placed on the spindle, A 6,
passes from the roll through a guide eye, C2, thence through a tensional stop-
motion device, C3, to an inner guide eye, C 4, in a bracket fixed to the lathe
rail, A 2. A shuttle, D, of the kind shown enlarged in Figures, 24 and 25, is in
Figures, 1 and 2, shown as having been picked or shot from the right-hand side of
the loom, and as having just homed in the left-hand shuttle box, A 4. The
shuttle, D, as shown has taken hold of the yarn, C, at its left-hand end ready for
leading the yarn through the shed in the next pick or shot which will be towards
the right. The tensional stop-notion device, (3, consists of a short horizontal
spindle held loosely in supports, and having on it two short arms one of which has
a guide eye at its end through which the yarn, C, passes. The other arm is
heavier and a small cord, C 5, fixed to it extends round a guide pulley, C 6, to a
small lever, C7, centered on the front of the batten, A 1. The tension. of the
yarn, C, when properly held by the shuttle, D, is such as to cause the cord, C 5, to
be drawn towards the side of the loom in a manner to hold the lever, C 7, inclined
from its vertical position. But if from any cause the tension of the yaru, C, is
insufficient the small lever, C 7, assumes a vertical position by the weight of its
lower arm, and then a projection on its upper arm acts on the knocking-off or loom-
stopping mechanism when the lathe beats up.
The shuttle, D, as shown in Figures, 1, 24, 25, has each end formed with a
jaw-like recess in which are fixed two springs, or grippers, D 1, arranged to press
When
against each other so as to hold the yarn, C, when inserted between them.
the shuttle is approaching the left-hand side of the loom the yarn, C, extends from
the guide, C4, in an inclined position down to a finger, E, which has turned down
upon it on the race, A 1. With the motion of the shuttle its left-hand grippers, D1,
take hold of the yarn end, which has previously been severed from the last left-to-
right weft shot, and removing it from the finger, E, carry it into the shuttle
box, A 4, and at the next pick lead it through the shed to the right hand. To
avoid complication in the drawings the warps and the shedding and picking
apparatus are omitted but may be the same as in existing looms. The holding
down finger, E, is centered on a small bracket, E1, fixed to the front of the
batten, A 1, and is formed with a short arm which is acted on by a horizontal
lever, E 2, centered on the same bracket, this lever being made with bent ends
projecting forward so as when the lathe beats up to encounter one or other of two
projections, E3, E 4, fixed on a horizontal bar, B2, fitted to slide in guides upon
the inner face of the breast beam, B. The bar, B2, is by devices hereinafter
described, moved at each successive shot to the right and to the left alternately,
and the projections, E 3, E 4, consequently act on the lever, E 2, so as at one shot
to lift the finger, E, and at the next to allow it to fall down on the race and hold
the
yarn.
When in approaching one end, say the left-hand end of the race, A 1, the
shuttle, D, has just taken hold of the yarn, C, with its left-hand grippers, D 1, a
protuberance, D2, on the top of the shuttle encounters the lower arm of a trigger
or lever, F, the upper arin of which is connected by a link, F1, to a detent
lever, F 2, (see enlarged Figures, 13, 14, 15, which are a plan and front and side

page_text: elevations) which is by a spring held in a notch in a vertically movable bar, G,
termed a dropper. This dropper, G, is held in a bracket, G 1, and is pressed
downwards by a helical spring, G 2, acting between the bracket and an enlargement
on the bar, when released by the action of the shuttle on the trigger, F, and
consequent outward movement of the detent lever, F 2. The parts are proportioned
and placed so that the dropper, G, descends and its bottom reaches the race, A 1,
just as the right-hand end of the shuttle passes from under it, and the dropper
consequently holds the end of the yarn just brought through the shed and causes it
to leave the right-hand grippers, D1, of the shuttle.
Certain of the parts hereinbefore described have to act alternately at opposite
sides of the loom and after each action parts have to be restored to positions
enabling them to act again when required. For these purposes a horizontal
rocking spindle, H, is carried in front of the lathe rail, A 2, in small bracket
bearings, H 1, fixed to the rail. The triggers, F, are centered on this rocking
spindle the trigger at the left-hand side being in a different angular position from
that of the trigger at the right-hand side-so that when one is in a position to be
acted on by the shuttle the other is by a small rocking movement of the spindle put
out of the way, and vice versa. For lifting up each dropper, G, after its descent a
lever, H 2, centered on a bracket, H 3, is provided, this lever being connected to
the top of the dropper, and being actuated by a cord attached to an eccentric, H 4,
on the rocking spindle, H, so that when the spindle is rocked (as hereinafter
explained) the dropper last dropped is raised and is held up by the spring detent
lever, F2, engaging in the notch in its side. The cord connecting one eccentric, H4,
to the lever, H 2, is on the outer side of the eccentric, the corresponding cord at the
other side of the loom being at the inner side of the other eccentric. Some of the
parts can be altered in position to suit the different widths of cloth that may be
woven in the same loom; and to facilitate such alterations a dovetail groove is
formed along the top of the rail, A 2, and the brackets, G1, H3, are made with
bases shaped to fit the groove, at any part of which each bracket may be secured
by a pinching screw or a wedge. The eccentrics, H4, the centres of the triggers, F,
and the thread guides, C4, can also be fixed at different parts of the rocking
spindle, H.
The rocking spindle, H, has fast on each end of it a short lever, H 5, that at the
left-hand end being directed downwards and that at the other end upwards; and at
each beat up of the lathe one or the other lever, H 5, encounters a projecting
stop, H 6, fixed to the bar, B 2, which is on the inuer side of the breast beam, B,
the encounter causing the spindle, H, to rock from the position it is then in into its
other position. The bar, B 2, is moved to the left at one beat-up and to the right
at the next beat up, and so on alternately, and the movement to the right carries
the left-hand stop, H 6, out of its position for acting on the rocking spindle, H, and
moves the right-hand stop into position for acting on the other lever (H5) of the
rocking spindle. Various devices may be used for moving the bar, B 2, as described,
that shown in Figures, 1, and 2, comprising a lever, B 3, the notched upper end of
which acts on a pin on the bar, whilst the lower slotted end of the lever is acted on
by an adjustable crank pin on a wheel, B4, which is by bevil or other suitable
gearing driven so as to make one revolution for every two of the crank shaft of the
loom.
For cutting the yarn when each weft length has been laid in a shed there is
provided towards each end of the breast beam, B, and adjustable so as to be placed
just beyond the lateral edge of the woven fabric, a pair of scissor blades, J, J 1,
(see Figure 5) the lower one, J, projecting horizontally inwards from the breast
beam, B, and formed in one piece or fixed to a part fixed to the top of the beam.
A movable blade, J 1, jointed to the fixed blade, J, is formed with a bell-crank
arm, J 2, which is pressed by a spring, J 3, tending to open the movable blade.
When the lathe beats up a projection, J 4, on it encounters the bellcrank arm, J 2,
and makes the movable blade, J 1, close down on the fixed blade, J, and sever the
yarn which will at that time be between the blades, J, and J 1.

page_text: Instead of the holding-down finger, E, herein before referred to there may be
used a device shown in Figures, 6 and 7, and which consists of a piece, K, placed
and centered within a groove in the race, A 1. This piece, K, is made with a
hump, K 1, which when the piece has to act is depressed by the dropper, G, the
other end being thereby tilted up. The tilting end is made with a jaw-like recess
having in it a pair of spring grippers which hold the end of the yarn in position for
being taken hold of by the shuttle when next approaching that side of the loom.
A spring, K2, in the groove in the race tends to draw the piece, K, out of the way
of the dropper, G, when its action is not required; and it is drawn into its acting
position when required by a cord fixed to its other end and passing round a pulley,
to an arm on a short spindle, K 3, centered in supports and having on it a second
arm which when the lathe beats up encounters a projection, K 4, on the breast-beam
bar, B2, this bar by its movements, already explained, causing the pieces, K, at the
two sides of the loom to act at alternate weft shots.
It is necessary for each yarn length to be held at both ends whilst being beat up
in order that it may not form into snarls or get out of place. The desired holding
action is obtained by the droppers, G, descending at both sides of the loom.
Whenever one trigger, F, is moved, a wire, F 3, which connects it to a lever, F 4,
at or near the middle of the lathe, makes that lever give a reverse movement by a
wire, F5, to the trigger (F) at the other side, the dropper (G) at the other side
being dropped in consequence. Similarly each eccentric, H4, besides being
connected directly to the lifting lever, H2, at the same side has fixed to it a
cord, H 7, which through a small lever, H 8, and continuation of the cord, acts on
the lifting lever, (H2) at the other side. The upper cord, H 9, shown in Figure, 2,
is the cord from the right-hand side which when the eccentric at that side acts,
pulls down the inner arm of the lifting lever, H 2, at the left-hand side.
In the apparatus as shown in Figures, 8 to 12, and 16 to 18, some of the devices
are modified so that amongst other things, the weft may be laid in the form of
loops, with one side length of each loop in one shed and the other side length in
another shed. In this arrangement the yarn is cut off from the roll not when a
single weft length has been laid but only when sufficient for two weft lengths
has been drawn off; and as the shed of the warps is changed between the laying of
the two lengths their loop end forms a kind of selvedge. Supposing the shuttle to
have taken hold of the end of the yarn at the left-hand side it lays it through a shed,
and leaves the end (held by the dropper) at the right-hand side; the shed then
changes and the shuttle returning to the left, draws yarn from the right-hand roll,
and lays a length of it in that shed. The shed again changes and the shuttle again
goes to the right a looping stud upon it engaging with the thread, not yet cut,
between the cloth and the left hand roll. By the time the shuttle has moved its
looping stud to about the middle of the cloth enough yarn will have been drawn off
the roll, and the yarn will thereon be cut whilst the shuttle continuing its journey
its looping stud will straighten out the yarn which it took into the shed as a loop.
With the described operations it follows that at each side of the loom the cutting
has to take place once for every four shots, the cutting actions at the two sides
alternating, with intervals of two shots. The cutting mechanism at each side which
has consequently to be modified so as to act only once for every four shots is shown
in Figures, 8, 9, 11, 12, and as enlarged in Figures, 16 to 18, which are a plan and
two side elevations, the last with some parts removed.
On a short horizontal spindle carried in bearings in fixed supports, L, there are
fixed two disks, L1, L2, and there is a stationary plate, L3, which has a square
guide groove formed in its inner face. In this guide groove there works a square
projection which is on one side of a block, L4, that has fixed to it the body part or
holder, J4, of a pair of scissor cutters, J 5, made like those of grape scissors or
fruit-gathering cutters with lips to keep hold of the yarn from which a weft length
The block, L4, has jointed to it a block fitted to work in a radial slot in
the disk, L2, being steadied by circular washers on both sides of the disk, so that
as this disk is moved round it causes the block, L4, to move parallel to the square
is cut.

page_text: guide groove in the plate, L 3. The outer disk, L1, is made with four projec-
tions, L5, shaped to engage with a pin projecting laterally from the inner end of
a plate, L6, hinged to a plate, L 7, which is fixed to the breast beam, B, (as best
seen in Figures 8, 11, 12, and as partly shown in dotted lines in Figure, 17).
The support, L, is fixed to the lathe batten, A 1, and when the parts are carried
forward at the beat up the pin of the plate, L 6, engages with a projection, L5,
of the disk, L 1, and causes that disk to make a quarter of a turn in the direction
of the arrow in Figure, 17. To arrest and steady the disk, L 1, in the position to
which it is turned a point held by a spring blade, L 12, engages in one of four
depressions made in the disk. The scissors, J 5, being in the position for cutting
the yarn that is at their upper innermost position will by such quarter turn be
lowered, and succeeding beats up each producing a quarter turn, will move the
scissors horizontally outwards, next upwards, into the position of Figure, 17, and
then inwards into the position in which their cutting action takes place. The
scissor-carrying block L 4, has passing through it a horizontal rod, L8, which
moves through and is guided by a plate, L 9, fitted to slide on a fixed vertical
rod, L 10, the combination assisting to guide the block when being carried through
its course by the disk, L 2. A helical spring, L 11, on the rod L 8, acts between
the plate, L9, and a collar on the rod, and tends to keep the inner end of the rod
pressed against a small rod fitted to slide inside of the body, J 4, of the scissors.
The small rod has fixed in it a pin, J 6, which projects through straight slots in the
body, J 4, and through curved slots in the back ends of the scissor blades, J 5, the
action of the pin in the curved slots being to open or close the scissors accordingly
as the pin moves in one direction or the other. In Figures, 8, 11, 12, 16, 17, 18,
the scissors, J 5, are shown as not in their innermost position, but when in that
position the pin, J 6, just touches a lever, M, centered on a bracket fixed to the
lathe rail, A 2, and the upper end of this lever is connected by a cord to a
horizontal bellcrank lever, M 1, which is acted on by a vertical lever, M 2. This
lever, M 2, is placed in a suitable position such that the shuttle, D, acts laterally
on it by a cam protuberance, D3, when a sufficient quantity of yarn has been
drawn into the shed. This action on the lever, M 2, causes the lever, M, to press
the scissors pin, J 6, and thereby close the scissors, J 5, and sever the yarn, the
scissors being afterwards opened again by the action of the helical spring, L 11,
on the rod, L 8. The shuttle, D, for this arrangement is shown enlarged in
Figures, 28, 29. It has formed at its outer side a groove in which there is fixed a
wire, D 4, having on it a slide made with a button-like head or stud, D 5. When
the shuttle is approaching the left-hand shuttle box the stud, D5, is at the right-
hand end of its wire, D4, and its engagement with the yarn is insured by a
finger, M 3, which bears the yarn down into a suitable position, this finger being
part of a bellcrank lever centered on the plate, L3, of the scissor apparatus the
short arm overhanging the top of the plate in a manner to be acted on by the
block, L4, when moving the scissors into their cutting position. The part of
the yarn thus caught by the stud, D5, extends as already mentioned from the edge
of the cloth to the thread guide, C 4, and on the shuttle next proceeding to the
right the stud forms a loop of the yarn and carries it into the new shed. Each
shuttle box, A. 4, has a slot formed in its front side to admit the stud, D5; and a
notch is formed in the bottom of the dropper, G, as indicated by dotted lines in
Figure, 15, so that the dropper may not hinder the movement of the yarn drawn
in by the stud, D 5.
Various devices for stopping the loom are provided for acting when there is
any failure in the laying of the weft threads, these devices being adaptations from
corresponding devices in existing looms. Thus as shown in Figures, 8 and 9, and
also in Figures, 1, and 2, there is the usual rocking spindle or shaft, N, beneath
the breast beam, B, which at one end acts on the stopping mechanism directly
connected with the driving clutch or fast-and-loose driving pulleys. This
spindle, N, has fast on it various projecting arms to be acted on by parts on the
lathe when beating up In the modification shown in Figures, 1, and 2, a lever, C 7,

page_text: has hereinbefore been described as arranged so as when in a vertical position to
cause stoppage of the loom. For this purpose its upper end is made to project
forward so as to encounter an arm, N 1, on the knocking-off spindle, N. In the
modification shown in Figures, 8 and 9, the lever, C 7, instead of acting directly
on the arm, N1, acts on an intermediate lever, N 2, which is itself carried by a
lever, N3; and this lever, N 3, is moved by the scissor mechanism so as to put the
lever, N 2, out of the way of the arm, № 1, excepting at the times when the
absence of the tensional action of the yarn on the device, C3, ought to cause
stoppage of the loom. Another arm, N 4, on the knocking-off spindle, N, has to
do with the shuttle-box swell detector which is substantially the same as in some
existing looms. When the shuttle, D, homes it presses out a spring blade, P,
which acts on an arm, P 1, on a rocking spindle, P 2, below the shuttle box. This
spindle, P2, has on it an arm, P 3, which when the spindle has not been moved by
the swell spring, P, is in a position to encounter the arm, N 4, and cause stoppage
of the loom. As this stoppage must be prevented when the shuttle homes
properly in the shuttle box at either side of the loom, the movement of one
spindle, P 2, is communicated to the other by means of a rocking spindle, P4,
centered in a low position in the lathe swords, A 3, and extending from one to
the other this low spindle, P4, being connected to the two upper spindles, P 2,
by levers and rods, P 5.

There remain to be described some modifications of details shown on Sheets, 3,.
and 4, of the drawings. As shown in Figure, 19, the scissors-carrying block, L4,
may be simply carried on an eccentric pin, on a disk, Q, the rod, L 8, guide
plate, L 9, and vertical guide rod, L 10, being adapted to give sufficient guidance..
Or the rod, L. 8, may be kept parallel as shown in Figure, 20, by being jointed
on eccentric pins on two disks, Q1, Q2, made with spur teeth and geared together
by means of a pinion, Q3. Figures, 22, and 23, are a plan and an elevation of a
device for turning the disk, Q, carrying the scissors, when different extents of
movement are required at different times. On the spindle of the disk, Q, there are
two partially toothed wheels, Q4, Q5, the teeth of one, for example, extending a
quarter round and those of the other three quarters. A kind of double rack,
is provided, being jointed to a bracket, Q7, fixed to the breast beam bar, B2,
which shifts the rack so that it will engage with the wheels, Q 4, Q 5, at alternate
shots. When either wheel, Q4, or Q5, has by the beat-up of the lathe moved
under the rack so as to be turned to the extent of the teeth on it, the rack
becomes lifted up on the untoothed part and stops further turning also preventing
turning back on the lathe receding inwards. Figure, 21, represents a device for
rocking the spindle, H, carried by the lathe, instead of effecting it by the breast
beam bar, B 2, as hereinbefore described. In this device a cam-grooved disk, R,
is carried in a support, R1, fixed on the breast beam, B, and the cam groove acts
on a pin or roller on a lever, R 2, which extends inwards so as to be encountered by
one or other of two short levers, H 5, fixed in the same position longitudinally on
the rocking spindle, H. On the cam-grooved disk, R, there is a ratchet wheel, R 3,.
which is acted on by a pawl lever, R4; and this lever, R4, is acted on by a
rod, R 5, guided in the support, R 1, and pressed inwards by a spring, R 6. When
the lathe beats up a projection, R 7, fixed on the batten, A 1, pushes the rod, R 5,
outwards, and the spring, R 6, afterwards moves the rod inwards making it then
act on the pawl lever, R 4, so as to turn the disk, R, a step. The cam groove of
the disk, R, is shaped so as to raise and lower the lever, R2, alternately at each
successive step, and to thereby cause the rocking of the spindle, H, alternately in
opposite directions.
The shuttle, D, shown in plan in Figure, 26, and in side elevation in Figure, 27,
difiers from that shown in Figures, 24 and 25, hereinbefore described in having a
metal strip, D 6, between each pair of grippers, D 1, for the purpose of receiving
and holding two yarns to be laid in each shed. Figure, 30, is a plan and Figure, 31,
is a side clevation of a modification of my yarn-gripping shuttle in which, instead
of spring blades, D 1, a spring-hinged finger, S, is fitted to the outer side of the

page_text: shuttle, D. The hinge may be like that of a pair of glove stretchers. When the
gripping part of the finger, S, is close to the side of the recess in which it is fitted
the other part, S1, projects outwards and at the proper times encounters obstructing
projections or levers suitably placed in the race, A 1, so as to become pressed
inwards and to open the gripping part for receiving or releasing the yarn.
When the apparatus is to be arranged for weaving with wefts of different colors
or otherwise different, there must be provided at one or at each side of the lathe
a vertically movable frame carrying rolls of the several wefts in different positions
and also carrying repetitions of the yarn-holding, cutting, and other necessary
parts, such frame being movable by adaptations of existing shifting shuttle-box
mechanism, to bring the several wefts into operation as required. Or the rolls
may be in fixed positions on the lathe or on the loom framing the several yarns
from them being passed through guides which move vertically with the other
parts.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved combination of parts of looms for weaving with weft drawn
oft rolls, cops, or bobbins placed at the sides of the loom the parts being arranged
and operating substantially as hereinbefore described with reference to Figures, 1,
to 5, of the accompanying drawings.
2. The improved combination of parts of looms for weaving with weft drawn off
rolls, cops, or bobbins placed at the sides of the loom the parts being arranged and
operating substantially as herein before described with reference to Figures, 8, to 12,
of the accompanying drawings.
3. In looms for weaving, the combination with suitable warp shedding and
shuttle picking apparatus, of shuttles having grippers to take hold of and draw
yarn from rolls, cops, or bobbins at the sides of the lathe, and lay it in successive
sheds of the warps substantially as herein before described.
4. In looms for weaving, the combination of shuttles adapted to take hold of
yarn from rolls, cops, or bobbins, at the sides of the lathe and lead it, through
warp sheds, with cutting mechanism for severing weft lengths or double weft
lengths substantially as hereinbefore described.
Dated this First day of March 1895.
