Improvements in Looms for Weaving.
A communication by WILLIAM FRANKLIN DRAPER, of Hopedale, County of
Worcester, in the State of Massachusetts, one of the United States of
America, Manufacturer.
I ALFRED GEORGE BROOKES of 55 & 56 Chancery Lane in the County of
London, Chartered Patent Agent do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
In the weaving of cloth, an operative usually tends from four to eight looms.
They are so constructed and arranged that when the filling is exhausted in the
shuttle, or breaks, the loom is stopped automatically.
When a warp thread breaks, and causes an imperfection in the cloth, the
weaving will continue until the weaver sees the defect and stops the loom, and
pieces the broken thread.
In such cases also it is frequently necessary to pick out several inches of cloth,
on account of a bad place made by a broken warp thread.
The frequency of change of filling, and of the breaking of warp threads, varies
with the size and quality of the yarn.
On an average it may be said that the filling breaks or runs out as often as
once in five minutes per loom, and a warp thread breaks as often as every half
hour.
It will be seen that as far as labor is concerned, the larger part of a weaver's
labor is in what is known as changing the shuttles, on account of the breakage of
filling.
At such times the shuttle needs to be removed from the loom, the bobbin, or
cop tube, removed from the shuttle, a fresh one substituted, the end of the yarn
sucked through the shuttle eye (generally by the mouth of the weaver) the shuttle
placed in the loom, and the loom started.
The work of mending broken warp threads is much less than that of changing
filling on most kinds of goods but it is necessary that the weaver should visit each
loom frequently, to see that no warp threads are broken; and when a warp thread
causes a pickout or bad place in the cloth, considerable extra labor is entailed
upon the weaver.
To summarize, a weaver's work consists principally in the changing of filling
and in watching for broken warp threads. The Specification of Patent No. 22939,
dated November 27, 1894 shews and describes a loom for the automatic intro-
duction of filling into the shuttle, whenever the filling in the shuttle should be
exhausted or breaks.
The use of the loom described in that Patent greatly reduced the labor of the
weaver so far as the changing of filling was concerned, as that labor was reduced
to the placing of bobbins in a hopper and attaching the ends of the threads to a
stud, the automatic operation of the loom performing the rest of the change.
More than this, the looms were enabled to run continuously, unless stopped by
the weaver for a broken warp thread, and the bobbins could be placed in the
hopper with the loom running, so that no time of the loom was lost, in the filling
change.
My correspondent however, discovered that increasing the number of looms to
be visited by the weaver, as could easily be done so far as the actual labor 'was

page_text: concerned, prevented the early discovery of the breakage of warp threads and the
consequent bad places in the cloth.
For this reason, the advantage which it was hoped might be gained by the use
of said patented invention, was largely neutralized, and the practical increase of
looms per weaver was found to be only about 25 per cent. where an equal standard
of cloth was maintained.
The idea of making a warp stop motion to stop the loom in case of the breaking
of a warp thread, next suggested itself to him as the best means by which the time
of the weaver, saved by the automatic filling changer, could be utilized.
Such an addition to an ordinary loom where the filling change was effected by
hand, would be of little, if any value, for the reason that the weaver would be
compelled to visit each loom every five minutes at least to change the filling, and
could then observe whether any warp threads were out that required to be
mended in.
The addition of the warp stop-motion bas enabled the full labor-saving value
of the filling changer to be utilized.
With both attachments applied. the weaver visits each loom to replenish the
filling, perhaps once in an hour and a half, and to replace a warp thread perhaps
once in half an hour, and in the latter case only when the loom is stopped on
account of the broken warp thread.
The two devices co-operate together, for the increase of production and for the
better quality of the cloth.
Imperfect cloth cannot be woven with both these devices attached, unless one
or the other is in some way out of order.
As before said, while the filling changer alone will increase a weaver's production
only about 25 per cent., and a warp stop motion alone probably less than that, both
co-operating together enable this production to be doubled.
By this arrangement, for the first time it is believed, a loom has been produced
in which both the filling, or weft, and every warp thread is always under control.
To effect this practically, there should be a warp stop motion contrivance, and
a plurality of individual devices under the control of the warp threads.
My correspondent has arranged these devices in such manner that the opening
of the shed will lift them, putting them into the desired relation with a feeler
having a feeling movement at each beat of the lay.
He has chosen to represent the invention in this present instance as embodied
with a loom substantially as shewn in said British Patent No. 22939, but it will be
understood that the invention is not limited to the particular construction shewn
for the automatically operating filling changing mechanism, nor to the exact form
shewn for the warp thread stop mechanism, so long as each warp thread is under
the control of one of a series of devices, the dropping of which will stop, the
loom.
This invention therefore consists in an organised loom containing automatic filling
supplying mechanism and warp stop mechanism having devices controlled by the
individual warp threads, and means to stop the loom when any single warp thread
breaks.
Also, in an organized loom containing the following instrumentalities, vis. :-
An automatic filling supplying mechanism, a warp stop mechanism containing a
series of devices operated by the breaking of a warp thread, shipping mechanism,
and devices between the same and the filling supplying and warp stop mechanisms
whereby on the occurrence of fault in the filling or warp, the shipping
mechanism will be operated to automatically stop the loom.
Also the use in a loom, of a bar having a series of metallic drop devices strung
thereon and provided with holes for the reception of warp threads, a vibrator
having notches to engage the edge of any drop device which may drop by the
breaking of a warp thread, and means to move said vibrator back and forth in the
direction of the length of the warp threads.
Also in the use in a loom, of a bar, a series of drop devices strung thereon and

page_text: adapted to drop when a warp thread breaks in the lower plane of the shed, each
device having an eye for the reception of a warp thread, a warp support extended
across the loom under the warp, and adapted to support the warp threads in the
lower plane of the shed, a vibrator, and means to move it to engage any drop device
which may drop due to the breaking of a thread, the stopping of the vibrator
effecting the stopping of the loom.
Also, in the use in a loom having transverse bars on which are strung two series
of flat metallic drop devices or heddles, each having slots at their ends to surround
said bars loosely in order that they may move vertically thereon independently of
said bars, and having also eyes for the reception each of a warp thread, and a
vibrator supported independently of said bars, and a shipper handle, of devices
intermediate said vibrator and said shipper handle whereby when one of said drop
devices resting on a warp thread in the lower plane of the shed drops by reason of
the breakage of a warp, the vibrator is arrested, and through its connections effects
the release of the shipper handle to stop the loom.
.
Also the use in a loom of a heddle-frame and cross-bar, a series of metallic
beddles adapted to move vertically independently of said bar, and a vibrator moved
back and forth in the direction of the length of the warp threads, and adapted to
engage any heddle which may be dropped.
Fig. 1 is a left hand side elevation of a sufficient portion of a loom, such as
described in said Patent, to enable my invention to be understood, the drop devices,
the vibrator, and its actuating means and most of the filling form and part of
arm A18 being omitted because shewn clearly in other figures;
Fig. 2 is a partial front view of a loom containing my invention, the lower parts
of the loom frame being broken off and the loom being broken out centrally to thus
economise space, a portion of the drop devices being also omitted.
Fig. 3 is a central section of the loom from front to back, the figure shewing
clearly one form of warp stop mechanism and actuating devices therefor;
Fig. 4 is a detail of the knock off lever and shipper handle and breast beam with
the finger carried by the said lever and adapted to be struck by a dog put into
position by the arrest of the vibrator due to the breaking of a warp thread and the
contact of the vibrator with a drop device;
Fig. 4 is an enlarged sectional view of the lay and two drop devices, one of
them having dropped and arrested the vibrator to stop the loom ;

Fig. 10, a detail of the filling fork with the latch down behind the knock off
lever.
The frame-work A contains suitable bearings for a crank shaft A having
connecting rods A' which are joined in usual manner to the lay A³, it having in
practice at its opposite ends a shuttle-box, and a suitable reed 10, the shuttle box
at one end of the loom being slotted through for the discharge of filling carriers
from the shuttle and out of the loom.
A pinion A on the crank shaft engages a gear A on the usual cam or picking
shaft A and rotates the latter in usual manner, the said shaft being driven by
power in any usual manner.
The loom frame supports a suitable filling feeder or hopper shewn as composed
of two disks a, a', adapted to receive and hold one the head or large end and the

page_text: other the tip or small end, of a series of filling carriers or bobbins b, upon which
is wound the filling, said feeder having a connected weft end support and a
device to which are attached the free ends of the filling on the filling thread
carriers.
Each filling thread carrier is taken automatically one after the other from the
feeder and pushed into the open side of a shuttle S, shewn in Figs. 1, 2 and 5,
whilst the latter is in the shuttle-box, by means of a pusher fl see Fig. 2, mounted
upon a stud frigidly supported on a suitable stand connected to the frame-work,
said pusher having an arm f upon which is pivoted a trip which is adapted to
be raised from its normal position, shewn in Fig. 1, into an abnormal position with
its end opposite a bunter ( connected to the lay whenever the filling breaks or
becomes exhausted in the shuttle, the trip being raised by means of a rod e" entering
loosely a sleeve e pivoted at e" on the pusher, the said rod being connected to a
short rock-shaft mounted in a bearing e secured to the frame-work, the rock-
shaft being turned by or through a suitable filling fork mechanism as will be
.described.
When the bunter meets the trip, the pusher is moved to act upon a filling carrier
then in the feeder and push it into the shuttle having a self threading slot S', and
as the shuttle is thrown from the shuttle-box the filling is automatically threaded
into the said slot and thence into the delivery eye of the shuttle.
When a filling carrier is being put into the shuttle, it meets the filling carrier
already in the shuttle and the latter filling carrier is ejected through the bottom of
the shuttle and through the slot referred to in the bottom of the shuttle-box.
A shews the usual picker stick, and A" the usual breast beam.
The breast-beam has mounted upon it by a screw 6º a stand 67 having a suitable
guide way 8, in which is adapted to reciprocate a slide upon which pivoted
at 61° the filling fork 6", said filling fork having a tail piece 6 which presents a
suitable projection adapted to be engaged by a hook 1, see Fig. 9, pivoted at 61
on the upper end of the filling hammer A, having an arm A18, actuated by a
cam A, see dotted lines Fig. 3, on the shaft Aº.
The hook slides on a support & carried by the said slide.
The slide 6 is shewn as provided with a check e pivoted at c, said check aiding
in turning the filling fork about its pivot 610 after it has been tilted by the filling.
The filling-fork slide has at its rear end a hooked projection against which
normally acts a lever c' pivoted at c³, said lever, in this instance of my invention,
being joined by a link to an arm of the rock shaft or rod d'; the normal
condition of said lever and said rock-shaft, as when the loom is weaving regularly,
being as represented in Figs. 1 and 6, a spring co connected at one end to the loom
frame, see Fig. 2, and at its other end to an arm cl fast on the shaft d' keeping
the arm c pressed against the said slide.
The filling fork slide has pivoted upon it at d' a latch d' having at its under side
a cam represented as a lump, as best shewn in Fig. 9 where part of the said latch is
shewn in section, the free end of the latch being represented in Fig. 10, as turned
down and adapted to co-operate with the knock-off lever b, said knock-off lever
being shewn in section in Figs. 6, 7, and 10, and pivoted at 142 on the usual slotted
plate 143 having at one side of the slot a notch in usual manner, to hold the
shipper handle and keep the belt or driving power on the fast pulley.
The filling-fork slide is provided with a suitable longitudinal passage for the
reception of a wedge d, the shape of which is best shewn in Fig. 9, said wedge
having a cam or lump and having its ends' enlarged, one end in the present
embodiment of my invention, viz. that nearest the filling-hammer A", being
turned upwardly, while the other end nearest the breast beam is turned downwardly,
the down turned end, marked 44, meeting, under conditions to be hereinafter
described, a shoulder 45, see Fig. 9, forming part of the stand 67, said shoulder
being projected upwardly sufficiently to be engaged at its opposite side by the
hooked end of the slide when the filling-fork occupies its position farthest
from the breast-beam toward the lay.

page_text: In practice the filling fork mechanism will normally stand in the position shewn
in Figs. 6, 8 and 9.
Now, if the loom is operated, and the filling is laid so as to meet and tilt the
filling-fork 6, the hook 6 connected with the filling-hammer A" and operated by
cam A, will be moved to the right, viewing Fig. 9, and then back again, without,
however, engaging the tail of the filling-fork, and consequently the filling fork slide
will not be pulled outwardly with relation to the breast-beam.
In case, however, that the filling-fork is not tilted, as it will not be in case the
filling is not in the shed opposite the filling-fork when the lay comes forward, then
the hook when it comes forward and goes back will catch the tail piece 61, of
the filling-fork and will draw the slide 6 with it and the downturned end 44 of the
wedge will meet the shoulder 45 of the stand and be stopped in stationary
position, thus letting the cam lump of the latch do pass the wedge do and drop from
the position Fig. 6 upon the knock-off lever 6 into the position Fig. 7.
During this first movement of the filling-fork slide due to the absence of filling
at the filling-fork, the lever e' will be turned into the position Fig. 7, and the rock
shaft or rod will be rocked to elevate the arm e, see Fig. 2, attached thereto
near its opposite end, and during such movement a lateral extension of said arm
will act against an arm e see Fig. 1 mounted upon a stud e carried by a stand e'
fastened upon the rock-shaft e, the movement of said arm e in the direction of the
arrow Fig. 1, resulting in turning the rock shaft e in its bearings, said rock-shaft
turning with it the rod e¹ connected thereto, and elevating the trip f" to meet the
bunter and effect the turning of the pusher " about the stud f, and put a bobbin
into the shuttle provided however the shuttle is in its proper position in the shuttle-
box, as provided for in said Patent.
Assuming that the shuttle has been automatically provided with a bobbin, while
the parts are in the position Fig. 7, and that the same has been thrown through
the shed and the filling is left opposite the filling-fork 6, then the lay A³ in its
next forward movement, the filling being present, will meet and tilt the filling-
fork, and the filling hammer A" will be moved forward and back in usual
manner, and as the upper end of the filling-hammer A1 completes its movement
toward the breast-beam A" it will strike the inner upturned end of the sliding
wedged and push it to the left, viewing Fig. 7, causing said wedge d to again lift
the latch d³ into the position Fig. 6, its normal position in the loom.
The catch do, is, it will be seen, permitted to drop during the first outward
movement of the filling-fork slide 6º; and it will also be understood, by reason of
the weight or spring 20 co-operating with the rock-shaft d' that as soon as the upper
end of the filling hammer starts toward the lay or away from the breast beam, the
lever acting upon the end of the filling-fork slide pushes it with it for a
sufficient distance to enable the latch d³ to meet, as in Fig. 7, pass and fall behind
the end of the knock-off lever, as represented in Fig. 10.
Should, however, the shuttle, it having been supplied with a new bobbin or
filling-carrier, be thrown through a shed and the filling not be threaded into the
delivery eye of the shuttle to enable it to leave filling opposite the filling-fork
when the latter is in the position represented in Fig. 10, then the filling-fork will
not be tilted, and the filling-hammer A" with its hook & will be moved forward
and as it comes back will engage the tail piece of the filling-fork and will draw
back with it a second time the filling-fork slide, causing the down turned end of the
catch d³, then resting against one side of the knock-off lever 65, as in Fig. 10, to
push the said knock-off lever far enough to release the shipper-handle H from its
notch in the usual notched-plate 143, and effect the stopping of the loom in usual
manner.
The parts referred to by letter are common to the said British Patent, but
therein designated in some instances by different letters so their operation need not
be herein more fully described.
The cam shaft A' has suitable cams 100 and 101, which act on levers 102

page_text: and 103, pivoted at 104, and connected by like straps 105 in an adjustable manner
with bars 110 112 having at their ends carriers 106 and 107, carrying at their
upper ends rods or bars 108, 109, the carriers being attached each at its opposite
enils to suitable chains or flexible connections 113, 114, running over like sprocket
wheels 115, attached to a shaft 116, mounted in a part of the loom frame.
The rods or bars 108, 109 have hung upon them the drop devices or heddles 117,
118, preferably made from sheet metal, and each provided with a suitable eye
as 211, see Fig. 4A, to receive a warp thread w, the upper ends of the drop
devices or heddles having slots of greater length than the width of the rods or
bars 108, 109, upon which they are strung, so that the said bars may be lowered
and leave the drop devices supported by the warp threads in the lower plane of
the shed.
The lower ends of the heddles or detectors enter or play loosely between two
warp supports 120, 121, located as shewn, one behind and the other in front of
the drop devices or heddles, said supports being extended across the loom and
connected to the end frames thereof in suitable manner, the supports sustaining
the warp threads left in the lower plane of the shed close to the path of
movement of the drop devices or heddles, so that the latter may rest upon the
threads left in the lower plane of the shed and be sustained uniformly thereby
and not be affected by the sagging of the warp threads which would result if
the said warp threads were not sustained between the fell of the cloth and the
usual whip roll 122, located above the usual warp beam A40.
The loom also has fixed with relation to its frame and extended across it near
the support 120, a beam having suitable guides 124, shewn only in Figs. 3
and 44, which latter receive suitable slides 125, jointed to brackets 127, depending
from the lay beam A'.
The slides 125 carry a rock shaft 126 having upright arms to which is secured
a vibrator 128, it preferably having, at its acting edges, a series of notches, see
Fig. 4, to embrace the edges of any drop devices or heddles which may be
dropped and prevent them from being twisted or turned around when struck by
the vibrator.
The shaft 126 has at or near one end an arm 130, to which is jointed a rod 131,
connected to a catch 132, pivoted at 133, on a stand 134 also attached to the lay at
its front side, said stand having pivoted to it at 135 a dog 136, shewn best in Fig. 4º,
it having a pin 137, and a notch 138, which when the dog turned down, as shewn
in full lines Fig. 3 and dotted lines Fig. 44, is entered by said catch 132, the latter
holding the dog down.
The pin 137 is connected with the arm 130, of the shaft 126 by a yielding or
spring connection, shewn in this instance as a strap 139 and a spring 140.
The spring is distended when the dog is down in its full line position Fig. 3, and
dotted position Fig. 44, and when the catch is moved to release the dog, the spring
throws the latter up into the full line position Fig. 44.
In the operation of a loom, all the warps being unbroken, the bar 108 or 109,
whichever is elevated in the production of a shed in the warp threads, will act on
the upper ends of the slots in the drop devices or heddles strung thereon.
Suppose the bar 109 is lifted, the drop devices or heddles 118, see Figs. 2 and 3,
will be used, putting their warp threads in the upper plane of the shed, but the
drop devices 117 will be left supported by the warp threads in the lower plane of
the shed, said threads resting upon the supports 120, 121, as in Fig. 3, the eyes of
the drop devices or heddles 117 being substantially at the level of the tops of said
support, and the upper ends of the slots in the drop devices or heddles 117 will be
above the upper side of the bar 108, as shewn by dotted lines Fig. 4^; and so long
as the warp threads are unbroken in the lower plane of the shed, the drop devices
or heddles which are so left down will have their lower ends all above the line of
movement of the vibrator 128 as the lay moves backwardly away from the breast
beam, and said vibrator will pass under the said drop devices and the lower end of

page_text: the support 120, and the rock-shaft 126 will not be turned, and the dog 136
will remain down, as shewn by full lines in Fig. 3.
On the contrary, however. should a warp thread left in the lower plane of the
shed break, then the drop device or heddle 117 previously supported upon it will
drop by gravity, between the supports 120, 121, until the upper end of the slot in
the said device meets the bar 108, as represented in full lines Fig. 4A, and the drop.
device or heddle is thus put in position to be struck by the vibrator 128, as the lay
completes its stroke away from the breast beam, and said vibrator will be arrested.
which causes the rock shaft 126 to be turned and the rod 131 to be moved in the
direction of the arrow Fig. 4, to pull the catch 132 out of the notch in the dog,.
leaving the dog to be pulled into its full line position Fig. 4A, so that said dog, as
the lay is next moved forward towards the breast beam, will strike the end of the
finger 140, connected to the said knock-off lever and extended over the filling fork,.
the said knock-off lever pushing the shipper handle H out of its holding notch and
permitting it to move in the slot in the plate 143 and through the usual belt
shipping mechanism M transfer the driving belt of the loom from the usual fast
onto the usual loose pulley and thus stop the loom.
The notched plate for holding the shipper handle is common to all looms.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what' I
claim is :-
