I, WALLACE FAIRWEATHER, C.E., of 62 Saint Vincent Street in the City of
Glasgow, Chartered Patent Agent, do hereby declare the nature of this invention
and in what manner the same is to be performed, as communicated to me to be
particularly described and ascertained in and by the following statement :-
This invention relates to improvements in cloth weaving looms, and more
particularly to that portion of the mechanism of same, by means of which the
filling thread is laid in.
The class of fabrics for the manufacture of which this invention is particularly
designed, is shown and described in a Patent, No. 361,360, granted by the United
States on the 19th day of April, 1887.
The principal advantages sought to be attained by this invention are:
1st. Saving of waste of the material, incident to the present methods and
machines, which waste is occasioned principally by the short lengths contained
within the exhausted shuttles; 2nd. Saving of time caused by stoppages of the
loom occasioned by renewal of the successive filled shuttles; 3rd. Saving of
labor by eliminating the necessity of close inspection over the loom to note the
exhaustion of the shuttle and thereby increasing the number of machines possible
for an operator to supervise; and 4th. The increased width of the fabric which
it is possible to manufacture with a loom built and operated in accordance with
this invention.

To facilitate the description of this invention, with reference to the drawings, it
is herein separated into its different elements, or instrumentalities, to each group of
which there has been assigned a letter common to the various parts thereof. And
to each member of the group has been given a distinguished numeral in con-
junction with the letter common to the group to which it belongs. Thus the
carrying mechanism and each part thereof is designated by the letter, A, in
common; the feed mechanism and each part thereof is designated by the letter, R,
in common; the driving mechanism and each part thereof is designated by the
letter, C, in common; and the controlling mechanism and each part thereof is
designated by the letter D, in common.
The distinctive feature of the method followed in the operation of this loom
exists in the manner of laying in the filling threads, which herein consists in laying
in short lengths of thread extending one across the web and returns and in
alternating these threads to cause each to bind or loop around the end of the
one adjoining. And further in supplying these short lengths from sources outside
the loom and on either side thereof, which sources may be renewed without
stoppage of the loom.
To lay in the filling thread, as above described it has to be prepared by forming
it into threads of the desired length, as it is laid in. For this purpose the
feeding mechanism, B, is designed. This consists in devices to grasp and
present the two ends of the lengths of the thread to a carrying mechanism; in
devices to measure the lengths; and in devices for cutting the thread when so
measured.
The first of these devices, that which presents the ends of the thread to the
carrying mechanism, consists of the plate B', Figs. 11 and 12, pivotally mounted
in bearing, B2, provided in the brackets, B3, at either end of the lay of the loom.
The plate B', is provided in the outer, or free, edge with the openings B', and B³,
into which the nipper jaws of the shuttle of the carrying mechanism successively
extend to grasp the ends of the lengths of thread, as they are held across the
openings. To grasp the thread the plates, B' are provided on their face with the
spring jaws, B shewn particularly at Fig. 12 which have openings in the outer edge
corresponding with, B, and B, of the plate B. The spring jaw, B, is firmly
attached to the plate, B', near the pivotal bearing thereof, and the forward ends
of the portions between the openings, B, and B, are curled outward and back to
form guides to lead the thread between the plate B¹ and said spring jaw when the
same is opened and shifting for a renewed grasp on the thread. To regulate
the position of the thread in crossing the openings, B4, B5, the pins B7 are
provided in the plate B', and extend through the jaw, Bs, to receive the thread
when the jaw is opened and the plate raised for a renewed grasp on the thread.
In its operation the plate, B', is rotated to assume the three positions shown in
Figs. 14, 15 and 16, of drawings in the order shown. In the first position the end
of the thread is taken from the opening, B4, by the shuttle which starts across the
lay to place it in position between the web threads. During the progress of the
shuttle across the lay, as described, the plate B', is thrown upward in the second
position the thread being released from the grasp of the spring jaw and running
freely through the guide tube, B8. As the shuttle reaches the far side of the lay,

page_text: the plate completes its upward movement, and the jaw B, which has been held
open closes and grasps the thread. The plate is now rotated to the third position,
presenting the opening, B, to the nipper jaws of the shuttle, when it is returned
across the lay. In thus descending from the second to the third position, the
thread is cut between the openings, B, and B, so that the shuttle takes the
last end of the same length it has previously laid in, on its next flight across
the lay.
It is to cut the thread, as above described, that the stationary and pivoted shear
blades, B and B10 are provided, while the end of the pivoted blade, B10, is further
employed to lift the spring jaw, 13, to release and receive the thread. The
stationary blade is rigidly mounted in the plate B', as shown. The blade B, is
pivotally mounted on the blade B, and is provided with the forked arm, B", by
means of which it is operated. The tines of the forked arm straddle the bent
rod, B2, the bends of which are employed to operate the pivotal blade, B, by
throwing the forked end of the arm B, in and out from the center of the rotation
of the plate. As the forked end of this arm is forced outward the blade B10, is
raised away from the blade, B, and impinges upon to force the spring jaw B, away
from the plate B' to release or receive the thread. To receive the end of the
blade, B10, the ends of the spring jaw, which extends to either side of the blade,
are bridged across by a small pin, B18 (Fig. 12). When, as in descending
from the second to the third position,-the forked end of arm B", is carried inward
the blade, B, is depressed upon and past the blade, B, cutting the interposed
thread in so passing.
The driving mechanism by which the plate is rotated is attached to the crank
arm, B, Fig. 1, at the back of the bearings, B2 on the further side of the lay.
As the various driving mechanisms for the various above named mechanisins are
in principle of construction the same, varying only in minor details, they will
be all described at the same time hereinafter.
The plates, B, and their attachments are in every respect the same at both ends
of the lay. The only difference which exists in the different sets is in the time
of their operation, this being arranged so that the positions of the plate, B',
and its attachments on the one side shall be successively duplicated on the other,
side of the loom of the lay, shall be assumed by the plate, B', on the right of the
lay when the shuttle reaches it after leaving the plate on the left side in that
position, and so on through the whole operation. By this means is insured the
binding the free ends of the short lengths of thread by the loop around the ends
as above set forth as being the peculiarity of the fabric.
In order that the lengths of thread may be uniform there has been provided a
measuring device by means of which the threads are measured off the exact
lengths before being cut by the cutting devices on the plates B'. This measuring
device consists of the thread receptacle comprised in its present form of the slotted
tubes, B, and B. These tubes are mounted perpendicularly under and slightly
in front of the plate B', in its third position with their slots facing each other. To
measure the thread it is caught from above by the vane, B17 which extends outward
from the rod, Bs, as the same is depressed. The depression of the vane B" takes
place as the shuttle, having taken the thread from the opening B4, in the position
shown at Fig. 14, starts across the lay and while the plate, B' is being rotated
upward. The vane, B, is forced down between the tubes, B1 and B16, carrying
the thread which has been spread across the mouth of the tubes, down into them.
As the vane is raised the thread remains in the tubes until drawn out by the flight
of the shuttle.
The vane B, Fig. 7, is mounted rigidly on the rod, B18, which is mounted in
guide openings in brackets, B, and Bo, in which it is operated up and down by
the driving mechanism provided for it and to which it is connected by the pivoted
rod, B21.
It is by raising and lowering the connection of the rod, B2, on the rod B18, that
variations are made in the lengths of the filling thread to accommodate various

page_text: widths of fabric. The stroke of the driving mechanism is constant, therefore by
raising the rod, B18, the vane B1, will not be carried so low between the tubes, B
and B, and consequently the quantity of thread drawn past the opened plate, B',
and spring jaw B, will be less than when the vane is drawn further down.
The thread having been deposited in the tubes, and the vane being raised, the
plate B', will be found in the position shown in Fig. 16 in which, as above set forth,
it presents to the shuttle the latter end of the cut lengths. The thread at this
stage of the operation is in the position as follows: The first half of the length
has been laid in and the shed of the warp has changed to bind it in position, the
half of the length now to be laid in extends from the warp to and down the
tube, B, and across and up the tube B15, to and across the opening, B' in
the plate, B', and spring jaw, Be, ready to be taken by the shuttle and to be carried
thereby across the lay.
To compel the thread to carry straight and to take from it all tendency to crinkle
or run into knots as it is withdrawn from the tubes, the tube B is provided at
its upper end with a straightening device which is a small curled piece of metal B²².
This straightening device is shown at Figs. 8, 9, 10, of drawings. In its present
form it consists of a small piece of oval-shaped metal, the blank of which is shown
at Fig. 7. This is curled upon itself, as shown in Figs. 8, 9, 10, and is of slightly
smaller diameter than the tube in which it is mounted. This mounting consists in
riveting the one end of the curled piece to the tube so that the free end rests
slightly to oue side of the slot in the tube.
When now the thread is depressed into the slot B₁s, it strikes upon the sloping
end of the curled piece, B22 and passes it to fall behind the same. As the thread
is now taken by the shuttle and thereby withdrawn from the tubes it follows over
the curled piece, the slight friction on which maintains the thread straight. When
the loop, which has been at the bottom of the measuring tubes, arrives at the
straightening device it strikes under the inclined edge up which it rises until freed
therefrom, passing out of the tube and drawn against the selvedge edge of the
fabric.
In setting the vane, B", for the proper measurement account is to be taken of
the extension of the lay from the fabric to the feed plate B', across which a good
proportion of the second half of the thread extends. The measuring device is to
take up the excess of the material required over and above that which extends
from the fabric to the feed plate as aforesaid.
The driving mechanism by which the measuring mechanism is operated is a part
of the general driving mechanism and will be described with that. The only
difference which exists is that of the timing its operations with reference to the
operation of the feed plate B', and spring jaw, B6, that their action is harmonious.
That this may be so the operation of the measuring mechanism to depress and
raise the vane is rapid and is timed to occur between the raising of the feed
plate, B to position nominated as second position, and its descending to the third
position. Between the second and third positions assumed by the plate B', there
is no movement on the part of the vane B, which remains in its raised normal
position.
Thus it will be seen the thread is taken from the source of supply and carried
through the guide tube, or eye, Bs, between the plate B', and spring jaw, B6, from
the different openings, B, and B, from which it is taken by the shuttle and laid
into the warp threads, measuring out the filling thread in double lengths and
severed from the source of supply when so measured; and that the operation on
the one side the lay is being successively duplicated on the other side, laying in the
filling threads from both sources.
In this manner it is apparent the supply provided for the shuttle is twice that
under other circumstances and as a consequence requires one half the attention on
the part of the operator, and this, though the two supplies were no greater than
that now carried by the ordinary shuttle. But it is equally evident that the
supplies required by this invention are unlimited and can be greatly increased over

page_text: and above the ordinary shuttle supply of the present loom, thereby further
diminishing the requirements for attention on the part of the operator as far as this
feature of the operation is concerned.
The shuttle, which has been several times mentioned above, forms the principal
feature of the carrying mechanism, A, by which the short lengths above described
are paid into the warp of the fabric. This shuttle is shown in detail at Fig. 17, of
drawings. It consists of the body, A', hollowed out in the center to provide the
valley, A, into which the adjusting finger of the controlling mechanism extends.
Also it is provided on the ends with the coue-shaped metal ferrules common to all
shuttles, to receive the impact of the picker sticks ant be thereby driven across
the lay. Set back from the said ferrules, from the plate path of the picker-sticks,
are the nipper jaws, A, A, on both ends of the shuttle. The jaws, as above
mentioned, are provided to grasp the threads as presented to them and to carry
them into the warp.
In thus handling these short lengths of thread it is necessary that the jaws of
the nippers open and close at the proper instant, and that the latter end of the
thread is laid smoothly in position, that is completely drawn out to the edge of the
selvedge. To accomplish this the jaw, A', is pivotally mounted on the shuttle and
is provided with a spring, A, to close it, while the jaw A, is mounted on the
shuttle stationarily. To open the jaws A', they are provided, to the rear of their
pivot, with a projection,-in this instance a pin, A7, which extends through the
body of the shuttle slightly beyond the face thereof. To operate against the
pin, A', to depress it and thereby open the jaw A, there is provided the spring
cam, A, Figs. 4, 5 and 18, set pivotally on the lay and the cam surface thereof
extended into the path of the pin A. This cam is maintained in its normal
position by the spring, A, against the shoulder, A. By its construction, and
arrangement, it is immovable by the pin when moving toward the feeding
mechanism, and thereby compels the jaw, A', to open until past the cam while in
the movement of the shuttle in the opposite direction the pin A', strikes behind
the cam and moves it against the tension of spring, A, away without opening the
jaw. The cam, As, is so placed that the jaw, A', is fully opened when the nippers
are entering the openings, B and B, of the feeding mechanism, and terminates
abruptly when the jaw A bas passed behind the thread end, held across the said
openings, and the small pin A10, on the said jaw has passed slightly beyond the
said thread. By the cam, As, terminating thus abruptly, the jaw A is suddenly
closed and imprisons the thread to hold the same by the tension of the spring, A³,
in its flight to the opposite side of the lay.
As the ends of the filling thread lengths are laid in the selvedge warp greater
care has to be exercised, and consequently slower speed on the part of the shuttle
so that there shall be no crinkling or knotting of the thread at this point. Also it
has been found advisable to introduce the nipper jaws in the openings, B, and B'
at a reduced speed. For this purpose the controlling mechanisin D is used.
The controlling mechanism herein shown consists essentially of devices to arrest
the flight of the shuttle at a certain point; and of other devices to propel the
shuttle from its arrested position into position to take the thread from the feed
plate, B.
The first of these devices consists of a pivoted latch, D', which extends into the
path of the picker stick, presenting a cam surface to its forward stroke, by which
the latch is raised to permit the head of the picker stick to pass freely under it iu
driving the shuttle. To the head of the picker stick on its return however the
latch presents au abrupt shoulder which holds the picker stick in that position to
receive the impact of the shuttle on its return flight to that side of the lay and
there arrest its movement. The thrust of this impact is received by the latch, D¹,
and transferred by it to the pivoted rod, D2 on which it is mounted. The
rod D is pivotally mounted in the reed-frame of the lay. The latch D' is
adjustably secured to the rod D2, by the set screw D³, it being possible thereby
to regulate the arrested position or the advanced position of the shuttle.

page_text: The object of thus arresting the progress of the shuttle is twofold as above
mentioned. The main of these objects. and for the accomplishment of which the
adjustment of the latch is provided,-is the desirability above referred to of laying
the ends of the lengths in the selvedge warp. In the present machine the shuttle
is arrested in position that the rear nipper jaw, or jaws having a grasp on the
thread, remain between the warp threads as the same close upon the threads just
laid in. As the shed is, being completed by the warp, and before entire com-
pletion, the shuttle is advanced to the end of its stroke and the rear end which has
been between the warp threads is withdrawn therefrom, laying in the end of the
filling thread smoothly.
To compel the thread ends to pull from the grasp of the nipper jaws evenly, the
jaw A, is provided with the small pin, A2, Fig. 17 over which the thread is com-
pelled to travel in drawing out the jaws of the shuttle. The movement of the
controlling mechanism is so timed with reference to the warp mechanism of the
loom that the shed is completed just as the jaws, A* A are withdrawn in fact
gliding over the tapered ends of the jaws with a considerable tension grasping
firmly the filling thread as it leaves the jaws and binding it into the fabric.
That part of the controlling mechanism by which the shuttle is advanced consists
of an arm, D, which is pivotally mounted on a standard, D5, at the back of the
lay. The arm D', is formed of sufficient length to extend down into the valley A³,
formed in the body, A', of the shuttle, and in sweeping forward to carry the nipper
jaws, A', A, into the openings, B4, B5 of the feed plate, before leaving the shuttle
in the completion of its full swing.
To free the shuttle, that it may be moved forward, the arm D', is provided with
an upwardly extended arm, D, carrying the loop D', in which rests the arm D³.
The arm D³, is rigidly secured to the latch, D', and as the D is swung around by
the movement of the arm D', the arm D8, and latch D' are raised, the latter being
lifted above the picker-stick and permitting it to pass. This lifting of the latch is
accomplished before the end of the arm D impinges upon the shuttle consequently
at that time there is no obstruction of the movement of the shuttle by the controlling
>mechanism.
The arm D', is connected to the driving mechanism by the crank D rigidly
secured to the arm, D', on the opposite side of the standard D. The driving
mechanism for this arm, D is timed to produce therein an even oscillation in
harmony with the beating of the lay or flight of the shuttle, that is to say as the
shuttle reaches the end of the lay in which is located the particular arm, D', that
operates on that side, it is swung down and outward moving the shuttle into position
as above described, and swinging further above and beyond it. By the time it
reaches the limit of its outward swing, the shuttle has been sent to the opposite
side of the lay. As the arm on the other side of the lay places the shuttle in
position the arm just described is rotated back to its first position from which it
begins to recede as the shuttle is started toward it.
The driving mechanism, by which these various instrumentalities are operated,
are similar in that each is operated by a cam wheel driven by the general driving
mechanism of the loom. Each also is provided with a lever pivotally mounted on
fulcrum brace rods at the rear of the machine, and each is connected with its
particular cam by a friction roller extended into the cam slot in each of the cam
wheels to produce in the outer end of the levers a timed rise and fall. The slots
in the cam wheels however differ in each instance to produce the peculiarity of
actions in the particular mechanism to which each is connected, and which have
been above described.
The lever C, the cam wheel C2, the connecting rods C3 and C, with the ball
-crank Cs, constitute the driving mechanism of the feed plate B' and by which it is
rotated to its several positions as above described. The cam wheel, C is provided
on the face with a convoluted cam slot C (Fig. 6), in which is set the pin C,
extended from the side of the lever, C', and which is provided with a friction
roller.

page_text: The cam slot C, is shaped to produce an upward or downward movement of the
end of the lever C, to raise and lower the connecting rod C³, and thereby operate.
the bell crank C and rod C, to throw the crank arm B, outward or inward and
rotate the plate B', to the various positions above described. That the cam C2,.
may act with reduced rapidity to produce the various movements required of the.
feed plate B', it is mounted on the driving shaft C3 which is geared to the regular
cam shaft of the ordinary loom by two to one gears, that is to say the cam C2 is..
rotated completely once to twice of the regular cam shaft; or the feed plate is
placed in all its various positions once completely to every two beats of the lay
and flights of the shuttle, the driving mechanism of which is timed with the regular
cam shaft. By this means the feed plate B', successively presents the first and
last ends of the short lengths of the filling threads.
Mounted on the same shaft, Cs is the cam wheel C which in conjunction with the
lever C, the rod Co, lever C", and pivoted rod B, constitute the particular driving.
mechanism for the operation of the measuring rod B. The cam in this wheel is.
simple but sharp in order that, as explained above. the entire movement of the said.
measuring rod will be completed in the interval between the first and third positions.
of the feed plate B. The lever C2, is pivotally mounted on the fulcrum rod C¹³, as.
in the lever C¹, and like it is connected to its cam wheel and similarly extended
through the openings, C, in each of the upright rods by which the movement of the
levers is communicated to the various mechanisms. In this instance however this.
motion is communicated from the upright rod C", by the lever C, which is pivotally
mounted on the pivotal shaft of the lay and extends laterally beyond the frame of
the loom, engaging in the upright rod Co, a pin C15, by means of a slot, C1, in itself..
At its end it is connected to the lower end of the rod, B", which is connected to the
rod 118 of the measuring device.
As the shaft C8 is rotated the feeding and measuring devices are operated thereby
and in perfect harmony, the same shaft operating both.
The controlling mechanism is provided with its particular driving mechanism,.
which consists in the cam wheel, C7, on the regular cam shaft of the loom, the
lever C, fulerumed on the rod C13, and connected to its cam wheel as described in.
the instance of the other two mechanisms; the upright connecting rod, C₁, the bell
crank C, and connecting rod C2, which reaches outward to engage the crank D°..
The operation of this driving mechanism differs from those described above only in
the time of operating, this operating in unison with the lay as described oscillating
synchronously with the flight of the shuttle.
While there has been described in this specification only the attachments as.
applied to one end of the lay, it will be understood these are duplicated at the
other end of the lay forming in the completed machine two entire sets. These sets.
differ only in the time of their action which is successive, the set on the one end
repeating the actions of the set on the other.
To aid in obtaining a full comprehension of this invention, I have shown.
at Fig. 19 a diagram of the manner of laying the filling threads in the warp (the
warp threads being omitted) which will be found more fully set forth in the patent
granted on this fabric as above mentioned.
In this diagram the filling threads will be seen in the form of interwoven loops.
leading in from both sides, thus the loops, a, from the left and the loops 3, from the
right.

the said arm to open and close the said shear blade, and a driving mechanism to
rotate the plate and spring jaw to present the openings in the same to the shuttle
of the carrying mechanism and to rotate the plate to an upright position between
the presentation to the upper and to the lower openings; in combination with a
carrying mechanism consisting of a shuttle adapted to engage the ends of the said
thread when so presented, and a driving mechanism to propel the shuttle from
side to side across the warp of the fabric, substantially as described.
10. In a loom, a feeding mechanism to deliver to a carrying mechanism the
filling thread from a source outside the loom, which consists of a plate pivotally
mounted on the lay of the loom, and having openings in the forward edge across
which the thread is held, a jaw mounted on said plate and adapted to close on and
hold the thread against the plate, a cutting device to sever the thread from the
supply while the said jaw is closed on the thread, and a driving mechanism to
rotate the said plate to present the said thread alternately on either side the said
cutting device; in combination with a carrying mechanism consisting of a shuttle
adapted to engage the said thread when presented, and a driving mechanism to
propel the shuttle from side to side across the warp of the fabric; and a controlling
mechanism to arrest the flight of the said shuttle before reaching the end of its
