Improvements in Looms for Automatically Feeding (without Stop-
ping the Loom) à Fresh Supply of Measured Lengths of Weft
to Shuttles when the Weft is Exhausted.
I, EDWARD HOLLINGWORTH, of the Firm of Hutchinson, Hollingworth and Company,
Limited, of Dobcross, in the County of York, Power Loom Makers, do hereby declare
the nature of this invention (which has been communicated to me by Randolph
Crompton and Horace Wyman, of the Crompton Knowles Loom Works, Worcester,
Massachusetts, in the United States of America, Power Loom Makers) to be as
follows:-
This invention has for its object to provide a magazine loom using a plurality of
shifting shuttle boxes, each containing a shuttle having a removable filling carrier
and having a filling carrier feeder and a transferrer to transfer a filling carrier from
the filling feeder into a shuttle in the usual stationary boxes contained within the
lathe with a plurality of measuring means, and means to actuate the same, and
means intermediate said measuring ineans and the transferrer to effect the operation
of the transferrer whenever the said measuring means indicate that the filling has
been substantially measured off from either of the said plurality of the filling
carriers in the plurality of shuttles contained in the shifting boxes.
In this class of loom where figures are produced by an employment of plurality
of colors of woof used in a certain predetermined order and for a certain number of
picks, it is a great desideratum to avoid leaving short ends of the filling in the shed,
that the filling be ejected from the shuttle just before it has been fully exhausted,
and to do this it is necessary that the filling be measured as it is taken from the
filling carrier.
We have devised measuring means for this purpose, measuring means which
co-operate with each shuttle used independent of the other shuttle so that each
shuttle is cared for whether it be used for a greater or less number of picks in
making the pattern.

The loom frame A, the crank shaft C having a gear C¹ engaging a gear C 2 on the
lower or cam shaft B, the latter having an arm provided with a stud a engaging
intermittingly slots in the master wheel D, mounted on a stud held in a bracket
B2, shafts c 2, d 2, having fast on them the pinions c and d actuated intermittingly by
the teeth of the master gear, said shafts having their bearings in said bracket, the
-shaft d 2 having) a crank connected by a link d¹ to the shuttle box lever E, the
shaft c 2 having an eccentric c 3 on which the shuttle box lever rests for its fulcrum,
the sliding forked hubs e having teeth to be put into and of line with the teeth
of said gear, said sliding hubs deriving their motion through levers e 2 operatively
connected by rods e 3, g 3, with suitable fingers e 4 resting upon a pattern surface or
chain g 5, the lay H actuated from the crank shaft by suitable connecting rods H¹,
the shuttle box rod n having at its upper end a series of, as herein shown, shuttle
boxes presenting two cells, and the shuttle box lever E suitably connected,-as by a
rod n 2 having a slip joint,-to the shuttle box rod.
The pattern surface surrounds a pattern shaft h 3 having at its inner end a ratchet
wheel h4 which is engaged by a pawl h 5 pivotted on a pawl carrier h6 having an
attached rod h7 jointed to the end of an elbow lever h 8 having its pivot on a shaft h I
and provided at its upper end with a catch h 10 having a shoulder h 13, which will be
herein further described when defining the invention herein contained.
The lever h8 is normally held towards its actuating can h 16 by a spring h 20
connected to it and to a lever h 21, also pivotted at h 9 and moved by a cam 126 said
lever h 21 having a slip connection h 22, which engages a pin h 23 on the lever h 8, but
whenever the catch is permitted to engage a shoulder of a slide bar 401, to be described,
the movement of the lever h 8 and the pattern surface for the shuttle-box mechanism
is stopped and the cam h 16 continues to rotate the lever h 21 then moving and the slip
device / 22 then slipping on the pin / 23, thus preventing the breaking of the parts
and allowing the pattern surface to stand still. The stopping of the pattern surface
is effected preparatory to operating the transferrer 26, to be described, so that the
pattern surface will remain in proper relation to the other working parts.
The frame of the loom is provided with suitable brackets G which receive a rock
shaft G¹, having two arms G 2, G3, the arin G 2 being connected by a link G4 with
the shuttle box lever E.
The arm G 3 of the rock shaft has connected to it a rack bar G 5, the said link, rock-
shaft, arms and rack constituting means for actuating the system of gearing for
moving the filling carrier feeder G 6 backwards and forwards in unison with the rising
and falling movements of the shuttle box.
The filling feeder G 6 as herein represented see Fig. 10 where the same is shown
detached, consists of a substantially circular cage composed of a hollow hub G 6 x,
provided at one end with a circular head 20, having extended horizontally from
it parallel to said hub, a series of arms or fins 25, said arins or fins at their
ends farthest from said head being connected to and supporting a toothed
ring 24.
The hollow hub G 6 x of the filling feeder is supported on a stud G 7 extended
horizontally from one side of a stand G 8 fixed on the breast beam A¹ of the
loom frame, the said hub being prolonged outside the head 20 by a second sleeve
G 9 connected to the outer side of said head, and to the said sleeve G 9 is
connected a filling end support G 10 and a filling end holder G 12, the filling
feeder being kept on the said stud by a suitable bolt G 13, see Fig. 1.

page_text: The head 20 of the filling feeder, has a series of radial notches, in which are
located suitable springs 21, one for each notch and against which springs the
tip of a filling carrier 22 will be placed, while the large or base end of each
filling carrier will be inserted in a pocket 23 of the toothed ring 24.
The series of horizontal arms or fins 25, as herein shown, divide the feeder into
compartments.
The internal diameter of the toothed ring 24 is such that the acting end of the
transferrer 26 to be hereinafter described, may enter and be moved freely therein,
said tranferrer when made to descend striking the filling carrier 22 then under it
and ejecting said filling carrier from the feeder into the shuttle 27 then in the
shuttle box below the feeder this action taking place whenever the yarn has been
nearly exhausted from the filling carrier then in the shuttle, but only after such
shuttle has arrived in the shuttle-box 27 x which is located under the said feeder,
said shuttle box being fixed to that end of the lay farthest from the shifting shuttle
boxes.
The shuttle 27 Fig. 11, is of that variety wherein there is a passage through it
from one side to the other side, in order that the filling carrier put into it at one
side may be ejected from it, at the opposite side, the said shuttle having suitable
filling carrier holders 28 of such shape as to receive rings or projections 29 of the
filling carriers 22, the shuttle also having a self or automatic threading contrivance
comprehending a slot d 20 and a horn 30, see Fig. 11, which may be of any of the
usual forms of construction, so that when a filling carrier in the filling carrier feeder,
said filling carrier having the end of its thread connected with the holder G 12, is
put by the transferrer into the shuttle,--that movement ejected the filling
carrier then in the shuttle through the shuttle and out from the bottom of the lay-,
the thread of said filling carrier, as the shuttle is thrown through the shed, will be.
automatically threaded into the slot d 20 and delivery eye d 23 of the self-threading.
contrivance of the shuttle, so that the shuttle will correctly deliver the filling from
it into the shed.
The filling feeder, herein described, has imparted to it two different sets of move-
ments one aiming to keep in working position or above the shuttle in operation, a
filling carrier of the same color, the other movement coming into play only after
the removal of a "filling carrier" from the feeder into the shuttle, the movement
being to skip to the next group of filling carriers and put in operative position with
relation to the shuttle, another group of filling carriers supplied with all the colors
of filling being used, putting a filling of the desired character or color just removed
from one group into operative position with relation to the shuttle then in use.
The filling carriers are arranged in the filling feeder in groups, and, inasmuch as in
this invention the shifting shuttle box is provided with two cells, the groups of filling
carriers are made of two each, each group of filling carriers being provided with
filling of different colours, as for instance, red and white, and these groups are
repeated as herein shown, nine times, and the shuttles in the cells of the shifting
shuttle boxes have, on starting of the loom, filling carriers, having filling of the
colors red and white.
The teeth of the toothed ring 24 of the filling feeder are engaged by the teeth of
a gear 31, mounted loosely on a stud 32, in a stand 31* the said gear having,
however, peculiar movements, as we will now describe.
The gear 31 has connected to it a stud 33 on which is loosely mounted a bevel
pinion 34 the said bevel pinion being engaged by the bevel teeth of a gear 35 loose on the
stud 32 and engaged by the teeth of the rack G 5 before described, said bevel
pinion 34 also engaging the bevel teeth of and moving a gear 36 also loose on said
stud 32, the bevel pinion 34 connecting the said two gears 35 and 36.
The teeth of the loose gear 36 are in mesh with a gear 32a mounted on the
stud 36a having an attached ratchet wheel 33x which may be moved intermittingly in
one direction only by a pawl 3+x.
The gear 31 may, therefore, be moved from two sources, that is, it may be oscillated
by the rack G 5, gear 35, bevel pinion 34, the gear 36 being then held fast, or it may

page_text: be rotated from the gear 32x as will be described, the rack and gear 35 being then
hield fast by the wheel 32x.
The pawl 34x is attached to a pawl carrier 35x, mounted on a stud 36a, the pawl
carrier having connected to its lower end a rod 37 attached to a lever 38 having its
fulcrum at 39 and acted upon by a cam 40 on the lower cam shaft B, the said pawl
thus having a constant motion, but the pawl cannot engage the ratchet wheel,
except when a filling carrier is to be ejected from a shuttle and a new one put into
the shuttle.
Let it be supposed that a shuttle box having a red filling is in position at the level
of the race of the lay and is working, and in such position the red filling in a group
of filling carriers is stopped immediately below the end of the transferrer, and so
long as that red filling goes in and the shuttle boxes are not shifted, the red filling
carrier stands in that position and the rack G 5 stands still, but if the next shuttle
from the red filling shuttle, viz. -the one containing white, should be brought into
position by shifting the shuttle box lever in usual manner, then that movement of
the shuttle-box lever through the operative mechanismn connecting it with the rack
G5, moves the said rack and effects the turning of the filling feeder far enough to
bring the white carrier in position below the transferrer.
It will consequently be understood that the filling feeder has an oscillating motion
in extent dependent upon the motion of the shifting shuttle boxes, and whatever the
movement of the shuttle boxes the filling feeder has a corresponding movement so as
to always preserve the proper relative arrangement of colors, and when a measured
quantity of the yarn on a filling carrier then in use has been measured off as will
be hereinafter described, the transferrer will be operated, as will be described, and
it will descend and take from the filling feeder a filling carrier having a filling of a
color corresponding with that in the shuttle in which new filling is to be placed,
and then thereafter comes in the new or second movement of the filling feeder.
One filling-carrier having been exhausted from a group of filling carriers, another
group of filling carriers must be instantly brought into position wherein all the
colors are represented, in order that should the same color be next required to be
taken from the filling carrier feeder that there would be opposite the transferrer a
filling carrier having filling of the proper color.
The second motion referred to herein described is one of progressive rotation, and
to effect this for the proper distance the pawl 34x is let come into play in the
following manner, viz.:-
The outer end of the pawl 34x, see Fig. 4, attached to the elbow lever 35x,
pivotted on a stud 36a lies normally on and is reciprocated backwards and forwards
over a pawl lifter 41x, and a pawl rest 40x; but normally the pawl is not moved off
from the said rest and it cannot consequently engage the teeth of the ratchet 33x to
turn it.
+
The pawl lifter 41x is pivotally mounted upon the pawl rest 40x, shown as a second
elbow lever mounted upon the stud 36a outside the lever 35x, one arm of said pawl
rest being shown as provided with an adjustable stud 42 which is embraced by the
slotted end of a pawl rest controller 43, shown as a lever having its fulcrum on a stud 44
projected from the stand G 8; the opposite end of said controller being also shown as
forked, see Fig. 4, and as embracing a pin 45 carried by the transferrer 26.
The transferrer carrying arm 26a is mounted upon a stud 47 secured to the fixed
stand G 8, and said arm is offset near its free end, to thus enable it to pass through
the gear 24 and support its acting end or portion which acts on the filling carriers,
above the said carriers.
-
The stud 47' has wound upon it a suitable strong spiral spring 48, the free end of
which engages the transferrer carrying arm, while the opposite end of said spring is
fixed with relation to the stud, the said spring normally keeping the transferrer
elevated, so that the filling carriers held in the feeder in the movement of the latter
may readily pass under the acting end of the transferrer.
The transferrer has a short arm 26a, see Fig. 4, and the lay beam has an attached
bunter H 3, and whenever a finger H4 attached to a sliding and rocking rod H 5, to be

page_text: herein further described, having suitable bearings under the breast beam, is moved,―
in this instance of our invention to the right, Fig. 1, far enough to put said finger
in the path of the short arm 26x of the transferrer and the bunter, the lay, as it comes
forward, causes the bunter to act on the finger and give the latter a quick movement
causing the finger to act on the arm 26x and move the transferrer carrying arm so
that it will act on and take the filling carrier then under it, from the filling feeder
and put it into the shuttle then in the stationary box, the incoming filling carrier
meeting and ejecting from the shuttle the filling carrier therein from which the yarn
has been nearly all measured off.
In order that the gear 32x may not be moved further than required, a suitable
spring pressed locking lever 49 see Fig. 4, has been provided, it having a roll, shown
in that figure by dotted lines, which enters notches in a notched wheel 50), also
shown by dotted lines.
#
While the transferrer is descending to act upon and remove a filling carrier from
the filling feeder the lever :43 is moved sufficiently to turn the pawl rest 40x a little
to the right, so that as the pawl 34x is again moved forward it slips over the end of
the said rest, drops into engagement with a tooth of the ratchet wheel 33x and gives
it a quick movement, the said movement taking place, however, after the transferrer
has effected its work, the movement being sufficient to move the filling feeder for a
distance equal to the space occupied by one group of filling, so that a filling carrier
of the same color may be brought into operative position under the transferrer after
a filling carrier has been ejected from the feeder, or in other words the filling carrier
which is brought by the movement of the feeder, due to the ratchet referred to in
position opposite the transferrer, will always be of the same color as that on the
filling carrier which was just removed from the feeder by the transferrer.
In practise the gears 36 and 32x will be in such proportion as to size, and the
ratchet teeth of the gear 32x will be in such number as to give to the filling feeder
the desired extent of movement, that depending upon the number of colors used in
the filling feeder and the number of shuttle boxes employed at the opposite end
of the loom..
This proportion may be varied at will according to the number of colors and
the work to be done.
The pawl 34x having reached the end of its back stroke, it having moved the
ratchet, again starts forward in the regular movement of the pawl, and the finger
projecting from the pawl strikes the free end of the pivotted pawl lifter 41x, said
end being downturned, so that it catches under and lifts the pawl from engagement
with the ratchet and enables it to slide back and forth on the pawl rest 40x until
the transferrer is again operated.
In this invention the movement of the transferrer is dependent upon, as herein
shown, the removal of a measured quantity of filling from a filling carrier.
The filling fork 50x, herein used to stop the loom when the filling breaks, is
pivotted at 51 on a slide 52, which is adapted to be reciprocated in a stand 53 fixed
to the breast beam A 1, the filling fork having at its inner end the usual heel, shown
by dotted lines Fig. 4, which. drops whenever the filling is absent from in front of
the filling fork as the lay beats forward, so that said heel is caught by the upper end
of the filling hammer 55.
This hammer is shown as a lever pivotted at 56 and having an arm 57 which is
acted upon by a suitable cam 58 on the shaft B, all in usual manner.
Any other usual form of self-threading shuttle of which there are many examples
may be employed.
We have mentioned that the filling are of different colors, but they may be of
different material or character, each one working in its own proper shuttle in a
defined order.
The systein of gearing herein shown to impart the described movements to the
feeder is one form of epicycloidal gearing, and instead, any other usual or equivalent
means may be employed to actuate the feeder.
The open ring like inner end of the filling feeder having the teeth to be engaged

page_text: by the pinion 31, is supported by arms or fins 25, but all the said fins are not
needed, and it is not essential to separate the filling carriers at any particular
spot.
The lever E controlled by the pattern chains e 5, determines by its movement not
only the position of a shuttle having filling of a particular color, but it also deter-
mines independently by or through the shaft G 1, the particular color of the filling on
the filling carriers to stand under the pusher.
In order that a filling carrier in a shuttle being used may be withdrawn from
operation after a stated length of filling has been taken from the filling carrier,
measuring means have been devised for measuring the filling as used, which means
will now be described.
This measuring means as it has been chosen to herein illustrate it, consists essen-
tially of two ratchet wheels 201 and 202, see Figs. 8 and 9, the one 201 having
twenty-one teeth, and the one 202 alongside of it having twenty teeth, the said
ratchet wheels being mounted on a stud 250 and both actuated by the same pawl 203
attached to an arm 210, see dotted lines Fig. 3 of the rock shaft h 9, constituting
the pivot for the levers h 8 and 21, said rock shaft having a second arm 213, which
is acted upon by a cam 214 on the shaft B. The bodies of these ratchet wheels run
between suitable friction blocks, 251, 252, which are restrained from rotation on said
stud, through the action of a suitable spring 253, the stress of which may be regu-
lated as desired by adjusting the collar 254.
These ratchet wheels.at their contiguous sides have each a flange, and each flange
has an opening of substantially one-half the area of the end of a leg 204 resting
with its lower end on both flanges.
The openings in these flanges when the loom is started do not register, and the
leg is consequently supported by the flanges, and it cannot enter the opening until
both register or come exactly opposite each other under the leg.
These openings will not register until after the said wheels have been moved
a number of times, equal to twenty multiplied by 21, or for 420, and as these wheels
are moved only at every other pick, the openings will not register until after 840
picks of filling have been put into the shed, which number, it will be supposed, will
exhaust most of the filling from the filling carrier used in the shuttle.
The number of teeth on these wheels may be varied, so that the product derived
from multiplying together the number of their teeth, may designate a greater or less
number of picks and consequently length of filling put into the shed by the flight of
the shuttle through it, and in this way provision may be made for stopping the use
of a filling carrier having a longer or shorter length of filling.
Two sets of these ratchet wheels are shown, for the reason that in this invention
two shuttles are employed, and each shuttle has consequently its own measuring
means, and.both these measuring means being alike it is unnecessary to particularly
describe, but one of them herein.
The second leg is marked 206 and its pair of ratchet wheels 215 and 216, they
being actuated by a pawl 304, also attached to the arm 213.
The leg 204 is jointed to an arm 207 of a rock-shaft free to turn in a bearing 208
at the end of an arm 210 mounted to turn on a pin 209, said pin having fixed to or
moveable with it a finger 217.
The rock-shaft carrying an arm 207 has an oppositely extended arm 218, to which
is connected the bent upper end of the leg, 206 so that the descent of either of
said legs into the registered openings of either of the flanges on which the legs
normally rest, will cause the finger 217 to descend.
The loom frame has.suitably connected with it, as shown in Fig. 7, at its inner
side, a stand a 12 having an upright pin 316 shown by dotted lines, on which is
mounted a rocking hub or shaft b 12 provided with two like guide lips d 12, said lips
receiving and guiding a drop device e 12, having at its lower end a lug f 12, a ping 12
extending through the drop device limiting its descent.
This drop device has pivotted on it at one side, as at h 12, a
atch m 12.
gravitating

page_text: The loom side sustains, see Fig. 3, a stand 400, in which is mounted a slide bar 401,
having a slot through which is passed the catch h 10, and at its upper end said slide
bar has a projection 403, to be hereinafter described.
When the loom is running regularly, the underside of the catch h 10 back of the
shoulder h 13, rests on the foot 404 of the stand 400, and the hook n 12 of the
catch h 10 occupies a position in and slides in a plane above the lug f 12.
The rock shaft G 1 in this instance of this invention is shown as utilized to govern
the pawls 203 and 304, for actuating the measuring means, said rock shaft having
oppositely extended arms 300 and 301, which are connected respectively with said
pawls by rods 302, 303, and inasmuch as the said rock shaft is moved in unison with
the shuttle box lever employed to raise and lower the shuttle boxes to put one or the
other color in place, said lever also effecting the movement to and fro of the feeder,
provided with the extra filling carriers, it follows that only one of said pawls will act
at every other beat of the lay, and the particular pawl to operate will depend upon
the particular shuttle being used.
In this way each ineasuring means will be actuated only while the particular shuttle
under its control is being used.
The pawl 203 is operated to turn the ratchets 201 and 202, when the lowest shuttle
box of the series is opposite the raceway of the lay, the other pawl 304 being operated
when the shuttle box next above the lowest one of the series is in position opposite the
raceway of the lay.
We will herein state that the shuttle box mechanism shown is capable of caring for
a set of three shuttles, but to use it for two shuttles, as we have herein described, we
have only to so modify the makeup of the pattern surface or chain that one or the
other of the shafts c 2 or d2 employed to move the shuttle box lever will not be
actuated.
Whenever in the operation of the loom a measured or indicated quantity of filling
has been run off or laid into the shed from a particular shuttle, the measuring means
co-operating with that shuttle then in operation presents in line the openings
herein before referred to made in its two flanges, and a leg before sustained by said
flanges, enters the opening, which results in turning the hub of the arm 210 on the
stud 209 and lowers the finger 217, it, in its descent, acting on the beveled edge of
latch m 12 and pushing it back, so that the finger passes below the lower end of the
catch.
This finger will be lowered which ever leg drops and enters an opening, and which-
ever leg enters the opening, it is lifted therefrom instantly, at the same pick in which
it entered, this being due to the shape of the lower end of the leg, and of the opening,
and the quick raising of the leg elevates the finger 217, causing it to strike the lower
end of the latch m 12 and lift with it the device e 12 putting the lug f 12, connected
to its lower end, in the range of movement of the hook n 12 of the catch h 10, said
catch turning the rock shaft 612 and causing the slide rod H 5 which is embraced by
the forked arm c 12 at the upper end of said rock shaft, to be slid longitudinally, said
movement putting the finger H 4 attached thereto between the short arm of the
transferrer 26 a, and the bunter, so that said bunter meeting the said finger H 4 turns
the transferrer as before described.
The partial rotation of the rock shaft 612 carries the latch m12 laterally off from
the upper side of the finger 217, which lifted the drop wire so that the drop device
may descend and put its lug f12 out of the range of movement of the catch h10.
The transferrer having been operated a suitable spring 59 acts immediately to
return the slide rod into its normal position and return the rock shaft 612 into its
normal position.
As the rock shaft b12 is returned into its normal position a pin on the latch m12
meets the convexed side of a finger 501 pivotted at 502, said pin by acting against
said finger being checked in proper position so that as the finger descends it will be
free from the latch. This latch rises when the drop device is lifted.
Herein, when the filling breaks the loom is stopped through the action of the
filling fork, and the take up and pattern surface are also stopped.

page_text: When the filling is absent from the front of the filling fork 50x, the downturned
heel at the opposite end of the fork is caught by the filling hammer 55, and the
filling fork slide, on which the filling fork is pivoted, is moved out wardly across the
breast beam.
This slide near its outer end has jointed to it a finger q2 which is pivotally
connected with a knock-off lever r2, pivoted at s2 on a stand secured to the loom,
said stand having a notched plate u2 to hold the shipper handle t2, the movement of
the filling fork slide, as described, causing the knock-off to push the shipper handle
out of its notch, it, in its movement, co-operating with usual belt shipper inechanism
not shown, and we shall hereinafter designate as the stopping mechanism, the
shipper handle and the usual parts to be actuated by it.
The upper side of the filling fork slide, has at its end a deep groove a20, in which
rests at all times the broadened or widened upper end of an arm 620 fixed to the
slide rod H 5, no matter what is the position of the said-slide rod or, in other
words, notwithstanding the sliding motion of said rod, the said broadened end of
the arm 620 always remains in the notch a20.
Consequently, when the filling fork slide is pushed outwardly as described; it, acting
on the arm 620, turns the slide rod H 5 (see Fig. 3) causing it to turn an attached
arm 404, the said arm meeting the projection 403 at the upper end of the slide 401,
thus lifting said slide, so that when the catch h10 comes again forward, the
shoulder 13 will meet a portion of said slide, which will stop the movement of the
catch h10 and the lever h8, and consequently will stop further movement of
the pattern surface or chain, the spring h20 at such time giving way and letting the
lever 21 move and the slip joint h23 break away from the pin h22.
So also during the rocking movement of this slide rod H 5, the finger H 4 at such
time not being in line with the short arm of the transferrer, a finger c20, see Fig. 4,
acts against the upper end of a holding pawl T employed to engage the ratchet wheel
of the take up, thus temporarily suspending the operation of the take up.
The particular construction of the ratchet or other wheels employed in the measuring
means, and the devices for actuating the measuring means, may be variously modified,
and instead we may employ as equivalents any usual speed decreasing mechanism
wherein a fast moving device or wheel, actuates another device or wheel at a
slower speed, so that the slow moving device, after it has passed over a defined space
will cause said slow moving device to operate suitable mechanism to effect the opera-
tion of the filling changing mechanism.
Referring to Fig. 8, showing a detail of the measuring means it will be seen that
the lower ends of the legs 204 and 206 are beveled to a rather fine point, and as soon
as both openings in the two flanges with which each leg co-operates present their
edges in alignment the leg will drop effecting the operation of the transferrer and
without stopping the movement of the measuring means the said leg is instantly
raised before the lay again comes forward, and so it is impossible to operate the
transferrer twice in immediate succession to make two successive changes of bobbin
carrier in the same shuttle.
In our invention we actuate the plurality of measuring means by a plurality of
pawls which are practically controlled by a pattern surface, and said pawls are put
into and out of position, in accordance with the change from one to another shuttle
in the series of shifting shuttle boxes, and these pawls are connected with the
shaft G 1, moved by the movement of the shuttle box shifting lever, in turn con-
trolled as to the time of its movement by the pattern surface.
The transferrer and its actuating parts constitute what is herein designated as
filling changing mechanism, and instead of the particular transferrer and the means:
shown for actuating it, any other suitable or well known filling changing mechanism
may be employed, and so also, instead of the particular filling feeder, any other suitable.
or well known device may be employed. .
This invention is not limited to the exact measuring means shown, nor to the
intermediate connections shown between the measuring means and the transferrer,
for it will be obvious to those skilled in the art, that these devices might be variously.

invention.
This invention is not limited to the particular mechanism shown intermediate
the measuring means and the transferrer, and instead of the devices thus far
specifically described, we may employ mechanism such as shown in Figs. 15 and 16.
In those figures the rod H 50, which takes the place of the rod H 5, is merely a
rocking rod, and it has a short arm H 40 on which is pivoted at y a finger y 1, con-
nected at its lower end with a rod y 2, in turn connected with one arm of an elbow
lever y 3, y 6 pivoted at y 4 in a stand y 5 depending from the breast beam, the arm y 6
of said lever being extended under the arm 210 which is fully shown in Fig. 6, and when
either of the legs connected with said arm enter the registered openings in the
measuring means, the said lever y 4, y 6 will be moved to turn the finger y 1, and put it
between the short arm 26x of the transferrer and the bunter before described con-
nected with the lay, the finger when so turned causing the transferrer to be worked.
Fig. 18 shows a third modification, the lever y 3, y 6 being reversed from the position
shown in Fig. 15.

Improvements in Looms for Automatically Feeding (without stop:
ping the Loom) a Fresh Supply of Measured Lengths of Weft
to Shuttles when the Weft is Exhausted.
I, EDWARD HOLLINGWORTH, of the Firm of Hutchinson, Hollingworth, and
Company, Limited, of Dobcross, in the County of York, Power Loom Makers, 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:
This invention has for its object to provide a magazine loom using a plurality of
shifting shuttle boxes, each containing a shuttle having a removable filling carrier
and having a filling carrier feeder and a transferrer to transfer a filling carrier from
the filling feeder into a shuttle in the usual stationary boxes contained within the
lathe with a plurality of measuring means, and means to actuate the same, and means
intermediate said measuring means and the transferrer to effect the operation of the
transferrer whenever the said measuring means indicate that the filling has been
substantially measured off from either of the said plurality of the filling carriers
in the plurality of shuttles contained in the shifting boxes.
In this class of loom where figures are produced by an employment of plurality of
colors of woof used in a certain predetermined order and for a certain number
of picks, it is a great desideratum to avoid leaving short ends of the filling in the
shed, that the filling be ejected from the shuttle just before it has been fully
exhausted, and to do this it is necessary that the filling be measured as it is taken
from the filling carrier.
We have devised measuring means for this purpose, measuring means which
co-operate with each shuttle used independent of the other shuttle so that each
shuttle cared for whether it be used for a greater or less number of picks in making
the pattern.
In the drawings left with the Provisional Specification Fig. 1 is front elevation

The loom frame A, the crank shaft C having a gear C¹ engaging a gear C2 on the
lower or cam shaft B, the latter having an arm provided with a stud a engaging
intermittingly slots in the master wheel D, mounted on a stud held in a bracket B²,
shafts c², d², having fast on them the pinions c and d actuated intermittingly by
the teeth of the master gear, said shafts having their bearings in said bracket,
the shaft d2 having a crank connected by a link d¹ to the shuttle box
lever E, the shaft c² having an eccentric c³ on which the shuttle box lever
rests for its fulcrum, the sliding forked hubs e having teeth to be put into and
out of line with the teeth of said gear, said sliding hubs deriving their motion through
levers e² operatively connected by rods es, g³, with suitable fingers e resting upon
a pattern surface or chain es, the lay H actuated from the crank shaft by suitable
connecting rods H³, the shuttle box rod n having at its upper end a series of, as
herein shown, shuttle boxes presenting two cells, and the shuttle box lever E.suitably
connected,-
-as by a rod N2 having a slip joint, to the shuttle box rod.
The pattern surface surrounds a pattern shaft ³ having at its inner end a ratchet
wheel which is engaged by a pawl h³ pivoted on a pawl carrier ho having an attached
rod h jointed to the end of an elbow lever hs having its pivot on a shaft h and
provided at its upper end with a catch h¹0 having a shoulder h, which will be herein
further described when defining the invention herein contained.
The lever h³ is normally held towards its actuating cam h¹6 by a spring h
connected to it and to a lever h21, also pivoted at hº and moved by a cam 126 said
lever 21 having a slip connection h2, which engages a pin h23 on the lever h³, but
whenever the catch is permitted to engage a shoulder of a slide bar 401, to be
described, the movement of the lever h8 and the pattern surface for the shuttle-box
mechanism is stopped, and the cam 10 continues to rotate the lever 21 then moving
and the slip device h22 then slipping on the pin 23, thus preventing the breaking of
the parts and allowing the pattern surface to stand still. The stopping of the pattern
surface is effected preparatory to operating the transferrer 26, to be described, so that
the pattern surface will remain in proper relation to the other working parts..
The frame of the loom is provided with suitable brackets G which receive a rock
shaft G¹, having two arms G2, G3, the arm G2 being connected by a link G4 with the
shuttle box lever E.
The arm G3 of the rock shaft has connected to it a rack bar G5, the said link,
rock-shaft, arms and rack constituting means for actuating the system of gearing for
moving the filling carrier feeder Go backwards and forwards in unison with the rising
and falling movements of the shuttle box.

page_text: The filling feeder G as herein represented see Fig. 10 where the same is shown
detached, consists of a substantially circular cage composed of a hollow hub Gox
provided at one end with a circular head 20, having extended horizontally from it
parallel to said bub, a series of arms or fins 25, said arms or fins at their ends farthest
from said head being connected to and supporting a toothed ring 24.
The hollow hub Gx of the filling feeder is supported on a stud G' extended
horizontally from one side of a stand G8 fixed on the breast-beat A¹ of the loom
frame, the said hub being prolonged outside the head 20 by a second sleeve G
connected to the outer side of said head, and to the said sleeve G is connected a filling
end support G10 and a filling end holder G12, the filling feeder being kept on the said
stud by a suitable bolt G13, see Fig. 1.
The head 20 of the filling feeder, has a series of radial notches, in which are located
suitable springs 21, one for each notch and against which springs the tip of a filling
carrier 22 will be placed, while the large or base end of each filling carrier will be
inserted in a pocket 23 of the toothed ring 24.
The series of horizontal arins or fins 25, as herein shown, divide the feeder into
compartments.
The internal diameter of the toothed ring 24 is such that the acting end of the
transferrer 26 to be hereinafter described, may enter and be moved freely therein,
said transferrer when made to descend striking the filling carrier 22 then under it
and ejecting said filling carrier from the feeder into the shuttle 27 then in the
shuttle box below the feeder, this action taking place whenever the yarn has been
nearly exhausted from the filling carrier then in the shuttle, but only after such
shuttle has arrived in the shuttle-box 27* which is located under the said feeder,
said shuttle-box being fixed to that end of the lay farthest from the shifting shuttle
boxes.
The shuttle 27, Fig. 11, is of that variety wherein there is a passage through it
from one side to the other side, in order that the filling carrier put into it at one
side may be ejected from it, at the opposite side, the said shuttle having suitable
filling carrier holders 28 of such shape as to receive rings or projections 29 of the
filling carriers 22, the shuttle also having a self or automatic threading contrivance
comprehending a slot do and a horn 30, see Fig. 11, which may be of any of the
usual forms of construction, so that when a filling carrier in the filling carrier feeder,
said filling carrier having the end of its thread connected with the holder G12, is put
by the transferrer into the shuttle,-that movement ejecting the filling carrier then
in the shuttle through the shuttle and out from the bottom of the lay, the thread
of said filling carrier, as the shuttle is thrown through the shed, will be automatically
threaded into the slot d20 and delivery eye 23 of the self-threading contrivance of
the shuttle, so that the shuttle will correctly deliver the filling from it into the
shed.
The filling feeder, herein described, has imparted to it two different sets of
movements one aiming to keep in working position or above the shuttle in operation,
a filling carrier of the same color, the other movement coming into play only after
the removal of a filling carrier from the feeder into the shuttle, the movement being
to skip to the next group of filling carriers and put in operative position with relation
to the shuttle, another group of filling carriers supplied with all the colors of filling
being used, putting a filling of the desired character or color just removed from one
group into operative position with relation to the shuttle then in use.
The filling carriers are arranged in the filling feeder in groups, and, inasmuch as
in this invention the shifting shuttle-box is provided with two, cells, the groups of
filling carriers are made of two each, each group of filling carriers being provided
with filling of different colors, as for instance, red and white, and these groups are
repeated as herein shown, nine times, and the shuttles in the cells of the shifting
shuttle boxes have, on starting of the loom, filling carriers, having filling of the
colors red and white.
The teeth of the toothed ring 24 of the filling feeder are engaged by the teeth of

page_text: a gear 31, mounted loosely on a stud 32, in a stand 31* the said gear having, however,
peculiar movements, as we will now describe.
The gear 31 has connected to it a stud 33 on which is loosely mounted a bevel
pinion 34, the said bevel pinion being engaged by the bevel teeth of a gear 35 loose
on the stud 32 and engaged by the teeth of the rack G³ before described, said bevel
pinion 34 also engaging the bevel teeth of and moving a gear 36 also loose on said
stud 32, the bevel pinion 34 connecting the said two gears 35 and 36.
The teeth of the loose gear 36 are in mesh with a gear 32* mounted on the
stud 36a having an attached ratchet wheel 33* which may be moved intermittingly
in one direction only by a pawl 34*.
The gear 31 may, therefore, be moved from two sources, that is, it may be
oscillated by the rack G³, gear 35, bevel pinion 34, the gear 36 being then held
fast, or it may be rotated from the gear 32%, as will be described, the rack and
gear 35 being then held fast by the wheel 32*.
The pawl 34 is attached to a pawl carrier 35*, mounted on a stud 36a, the pawl
carrier having connected to its lower end a rod 37 attached to a lever 38 having
its fulcrum at 39 and acted upon by a cam 40 on the lower cam shaft B, the
said pawl thus having a constant motion, but the pawl cannot engage the ratchet
wheel except when a filling carrier is to be ejected from a shuttle and a new one
put into the shuttle.
Let it be supposed that a shuttle box having a red filling is in position at the
level of the race of the lay and is working, and in such position the red filling in a
group of filling carriers is stopped immediately below the end of the transferrer,
and so long as that red filling goes in and the shuttle boxes are not shifted, the
red filling carrier stands in that position and the rack G5 stands still, but if the next
shuttle from the red filling shuttle, viz. :-the one containing white, should be
brought into position by shifting the shuttle box lever in usual manner, then
that movement of the shuttle-box lever through the operative mechanism con-
necting it with the rack G³, moves the said rack and effects the turning of the
filling feeder far enough to bring the white carrier in position below the transferrer.
It will consequently be understood that the filling feeder has an oscillating
motion in extent dependent upon the motion of the shifting shuttle boxes, and
whatever the movement of the shuttle boxes the filling feeder has a corresponding
movement so as to always preserve the proper relative arrangement of colors, and
when a measured quantity of the yarn on a filling carrier then in use has been
measured off as will be hereinafter described, the transferrer will be operated, as
will be described, and it will descend and take from the filling feeder a filling
carrier having a filling of a color corresponding with that in the shuttle in which
new filling is to be placed, and then thereafter comes in the new or second
movement of the filling feeder.
One filling-carrier having been exhausted from a group of filling carriers, another
group of filling carriers must be instantly brought into position wherein all the colors
are represented, in order that should the same color be next required to be taken
from the filling carrier feeder that there would be opposite the transferrer a filling
carrier having filling of the proper color.
The second motion referred to herein described is one of progressive rotation, and
to effect this for the proper distance the pawl 34* is let come into play in the following
manner, viz. -
The outer end of the pawl 34*, see Fig. 4, attached to the elbow lever 35*, pivoted
on a stud 36* lies normally on and is reciprocated backwards and forwards over a
pawl lifter 41, and a pawl rest 40*, but normally the pawl is not moved off from the
said rest and it cannot consequently engage the teeth of the ratchet 33 to turn
it.
The pawl lifter 41 is pivotally mounted upon the pawl rest 40%, shown as a second
elbow lever mounted upon the stud 36 outside the lever 35, one arm of said pawl
rest being shown as provided with an adjustable stud 42 which is embraced by the
slotted end of a pawl-rest controller 43, shown as a lever having its fulcrum on a

page_text: stud 44 projected from the stand G8, the opposite end of said controller being also
shown as forked, see Fig. 4, and as embracing a pin 45 carried by the transferrer 26.
The transferrer carrying arm 26* is mounted upon a stud 47 secured to the fixed
stand Gs, and said arm is offset near its free end, to thus enable it to pass through
the gear 24 and support its acting end or portion which acts on the filling carriers,
above the said carriers.
The stud 47 has wound upon it a suitable strong spiral spring 48, the free end of
which engages the transferrer carrying arm, while the opposite end of said spring is
fixed with relation to the stud, the said spring normally keeping the transferrer
elevated, so that the filling carriers held in the feeder in the movement of the latter
may readily pass under the acting end of the transferrer.
The transferrer has a short arın 26, see Fig. 4, and the lay beam has an attached
bunter H³, and whenever a finger H' attached to a sliding and rocking rod H³ to be
herein further described, having suitable bearings under the breast beain, is moved,-
in this instance of our invention to the right, Fig. 1, far enough to put said finger
in the path of the short arm 26 of the transferrer and the bunter, the lay, as it comes
forward, causes the bunter to act on the finger and give the latter a quick movement
causing the finger to act on the arm 26* and move the transferrer carrying arm so
that it will act on and take the filling carrier then under it, from the filling feeder
and put it into the shuttle then in the stationary box, the incoming filling carrier
meeting and ejecting from the shuttle the filling carrier therein from which the yarn
has been nearly all measured off.
In order that the gear 32* may not be moved further than required, a suitable
spring pressed locking lever 49, see Fig. 4, has been provided, it having a roll, shown
in that figure by dotted lines, which enters notches in a notched wheel 50, also
shown by dotted lines.
While the transferrer is descending to act upon and remove a filling carrier from
the filling feeder, the lever 43 is moved sufficiently to turn the pawl rest 40* a little
to the right, so that as the pawi 34* again moved forward it slips over the end of the
said rest, drops into engagement with a tooth of the ratchet wheel 33* and gives
it a quick movement, the said movement taking place, however, after the
transferrer has effected its work, the movement being sufficient to move the filling
feeder for a distance equal to the space occupied by one group of filling, so that a
filling carrier of the same color may be brought into operative position under the
transferrer after a filling carrier has been ejected from the feeder, or in other words,
the filling carrier which is brought by the movement of the feeder, due to the ratchet
referred to, in position opposite the transferrer, will always be of the same color as
that on the filling carrier which was just removed from the feeder by the transferrer.
In practise the gears 36 and 32* will be in such proportion as to size, and the
ratchet teeth of the gear 32* will be in such number as to give to the filling feeder
the desired extent of moveinent, that depending upon the number of colors used
in the filling feeder and the number of shuttle boxes employed at the opposite
end of the loom.
This proportion may be varied at will according to the number of colors and
the work to be done.
The pawl 34 having reached the end of its back stroke, it having moved the
ratchet, again starts forward in the regular movement of the pawl, and the finger
projecting from the pawi strikes the free end of the pivoted pawl lifter 41*, said
end being downturned, so that it catches under and lifts the pawl from engage-
ment with the ratchet and enables it to slide back and forth on the pawl
rest 40* until the transferrer is again operated.
In this invention the movement of the transferrer is dependent upon, as herein
shown, the removal of a measured quantity of filling from a filling carrier.
The filling fork 50, herein used to stop the loom when the filling breaks, is pivoted
at 51 on a slide 52, which is adapted to be reciprocated in a stand 53 fixed to the
breast beam A, the filling fork having at its inner end the usual heel, shown by
dotted lines Fig. 4, which drops whenever the filling is absent from in front of the

page_text: filling fork as the lay beats forward, so that said heel is caught by the upper end of
the filling hammer 55.
This hammer is shown as a lever pivoted at 56 and having an arm 57 which is acted
upon by a suitable cam 58 on the shaft B, all in usual manner.
Any other usual form of self-threading shuttle of which there are many examples
may be employed.
We have mentioned that the fillings are of different colours, but they may be of
different material or character, each one working in its own proper shuttle in a
defined order.
The system of gearing herein shown to impart the described movements to the
feeder is one form of epicycloidal gearing, and instead, any other usual or equivalent
means may be employed to actuate the feeder.
The open ring-like inner end of the filling feeder having the teeth to be engaged.
by the pinion 31, is supported by arms or fins 25, but all the said fins are not needed,
and it is not essential to separate the filling carriers at any particular spot.
The lever E controlled by the pattern chains es, determines by its movement not
only the position of a shuttle having filling of a particular color, but it also determines
independently by or through the shaft G¹, the particular color of the filling on the
filling carriers to stand under the pusher.
In order that a filling carrier in a shuttle being used may be withdrawn from
operation after a stated length of filling has been taken from the filling carrier,
measuring means have been devised for measuring the filling as used, which means
will now be described.
This measuring means as it has been chosen to herein illustrate it, consists essen-
tially of two ratchet wheels 201 and 202, see Figs. 8 and 9, the one 201 having
twenty-one teeth, and the one 202 alongside of it having twenty teeth, the said
ratchet wheels being mounted on a stud 250 and both actuated by the same pawl 203
attached to an arm 210, see dotted lines Fig. 3 of the rock shaft ho, constituting the
pivot for the levers h³ and h21, said rock shaft having a second arı 213, which is acted
upon by a cam 214 on the shaft B. The bodies of these ratchet wheels run between
suitable friction blocks 251, 252, which are restrained from rotation on said stud,
through the action of a suitable spring 253, the stress of which may be regulated as
desired by adjusting the collar 254.
These ratchet wheels at their contiguous sides have each a flange, and each flange
has an opening of substantially one-half the area of the end of a leg 204 resting with
its lower end on both flanges.
The openings in these flanges when the loom is started do not register, and the leg
is consequently supported by the flanges, and it cannot enter the opening until both
register or come exactly opposite each other under the leg.
These openings will not register until after the said wheels have been moved a
number of times, equal to twenty multiplied by 21, or for 420, and as these wheels
are moved only at every other pick, the openings will not register until after 840
picks of filling have been put into the shed, which number, it will be supposed, will
exhaust most of the filling from the filling carrier used in the shuttle.
The number of teeth on these wheels may be varied, so that the product derived
from multiplying together the number of their teeth, may designate a greater or less
number of picks and consequently length of filling put into the shed by the flight of
the shuttle through it, and in this way provision may be made for stopping the use
of a filling carrier having a longer or shorter length of filling.
Two sets of these ratchet wheels are shown, for the reason that in this invention
two shuttles are employed, and each shuttle has consequently its own measuring
means, and both these measuring means being alike it is unnecessary to particularly
describe but one of them herein.
The second leg is marked 206 and its pair of ratchet wheels 215 and 216, they
being actuated by a pawl 304, also attached to the arm 210.
The leg 204 is jointed to an arm 207 of a rock-shaft free to turn in a bearing 208 at

page_text: the end of an arm 210 mounted to turn on a pin 209, said pin having fixed to or
movable with it a finger 217.
The rock shaft carrying an arm 207 has an oppositely extended arm 218, to which
is connected the bent upper end of the leg, 206 so that the descent of either of said
legs into the registered openings of either of the flanges on which the legs normally
rest, will pull down the arm 210, and, as finger 217 is fast on stud 209 it also will be
rocked in a downward direction.
The loon frame has suitably connected with it, as shown in Fig. 7, at its inner
side, a stand a having an upright pin 316 shown by dotted lines, on which is
mounted a rocking hub or shaft 612 provided with two like guide lips 12, said lips
receiving and guiding a drop device e12, having at its lower end a lug f12, a pin giz
extending through the drop device limiting its descent.
This drop device has pivoted on it at one side, as at ha gravitating latch m¹².
The loom side sustains, see Fig. 3, a stand 400, in which is mounted a slide bar
401, having a slot through which is passed the catch 10, and at its upper end said
slide bar has a projection 403, to be hereinafter described.
When the loom is running regularly, the underside of the catch h¹0 back of the
shoulder h3 rests on the foot 404 of the stand 400, and the hook 12 of the catch h10
occupies a position in and slides in a plane above the lug f12, at the foot of vertical
dropping bar e¹².
The rock shaft G¹ in this instance of this invention is shown as utilized to govern
the pawls 203 and 304, for actuating the measuring means, said rock shaft having
oppositely extended arms 300 and 301, which are connected respectively with said
pawls by rods 302, 303, and inasmuch as the said rock shaft is moved in unison
with the shuttle box lever employed to raise and lower the shuttle boxes to put
oue or the other color in place, said lever also effecting the movement to and
fro of the feeder, provided with the extra filling carriers, it follows that only one
of said pawls will act at every other beat of the lay, and the particular pawl to operate
will depend upon the particular shuttle being used.
In this way each measuring means will be actuated only while the particular
shuttle under its control is being used.
The pawl 203 is operated to turn the ratchets 201 and 202, when the lowest
shuttle box of the series is opposite the raceway of the lay, the other pawl 304 being
operated when the shuttle box next above the lowest one of the series is in position
opposite the raceway of the lay.
We will herein state that the shuttle box nechanism shown is capable of caring for
a set of three shuttles, but to use it for two shuttles, as we have herein described, we
have only to so modify the make up of the pattern surface or chain that one or
the other of the shafts c² or employed to move the shuttle box lever will not be
actuated.
Whenever in the operation of the loom a measured or indicated quantity of filling
has been run off or laid into the shed from a particular shuttle, the measuring means
co-operating with that shuttle then in operation presents in line the openings
herein before referred to made in its two flanges, and a leg before sustained by said
flanges, enters the opening; which results in turning the hub of the arm 210 on the
stud 209 and lowers the finger 217 which is also fast on the stud 209, said finger in
its descent, acting on the beveled edge of the latch m¹² and pushing it back, so that
the finger 217 passes below the lower end of the catch m³.
This finger 217 will be lowered which ever leg drops and enters an opening, and
which ever leg enters the opening, it is lifted therefrom instantly, at the same pick
in which it entered, this being due to the shape of the lower end of the leg, and of
the opening, and the quick raising of the leg elevates the finger 217, causing it to
strike the lower end of the latch m12 and lift with it the device el putting the lug f¹²,
connected to its lower end, in the range of movement of the hook 12 of the catch h10,
said catch turning the rock shaft 612 and causing the slide rod H5 which is embraced
by the forked arm c¹² at the upper end of said rock shaft, to be slid longitudinally,
said movement putting the finger H* attached thereto between the short arm of the

page_text: transferrer 26ª, and the bunter, so that said bunter meeting the said finger H
turns the transferrer as before described.
The partial rotation of the rock shaft 612 carries the latch m12 laterally off from the
upper side of the finger 217, which lifted the drop wire so that the drop device may
descend and put its lug 12 out of the range of movement of the catch ¹º.
The transferrer having been operated, a suitable spring 59 acts immediately to
return the slide rod into its normal position and return the rock shaft 612 into its
normal position.
As the rock shaft 612 is returned into its normal position a pin 500 on the latch m¹²
meets the convexed side of a finger 501 pivoted at 502, said pin 500 by acting against
convexed side of finger 501 is checked in proper position so that as the finger 217
descends it will be free from the latch m2. This latch m¹ rises when the drop
device e¹² is lifted to which it is attached by pin h¹².
Herein, when the filling breaks the loom is stopped through the action of the
filling fork, and the take-up and pattern surface are also stopped.
When the filling is absent from the front of the filling fork 50%, the down-
turned heel at the opposite end of the fork is caught by the filling hammer 55,
and the filling fork slide, on which the filling fork is pivoted, is moved outwardly
across the breast beam.
This slide near its outer end see Fig. 5 has jointed to it a finger q2 which is
pivotally connected with a knock-off lever 2, pivoted at 82 on a stand secured to
the loom, said stand having a notched plate u to hold the shipper handle 2, the
movement of the filling fork slide, as described, causing the knock-off to push the
shipper handle out of its notch, it, in its movement, co-operating with usual belt
shipper mechanism not shown and we shall hereinafter designate as the stopping
mechanism, the shipper handle and the usual parts to be actuated by it.
The upper side of the filling fork slide, has at its end a deep groove a20, in which
rests at all times the broadened or widened upper end of an arm 620 fixed to the slide
rod H³, no matter what is the position of the said-slide rod or, in other words,
notwithstanding the sliding motion of said rod, the said broadened end of the
arm 60 always remains in the notch a20.
Consequently when the filling fork slide is pushed outwardly as described, it, acting
on the arm 60, turns the slide rod H³, (see Fig. 3) causing it to turn an attached
arm 404, the said arm meeting the projection 403 at the upper end of the slide 401,
thus lifting said slide, so that when the catch h¹ comes again forward, the shoulder his
will meet a portion of said slide, which will stop the movement of the catch hio and
the lever h, and consequently will stop further movement of the pattern surface or
chain, the spring h" at such time giving way and letting the lever h" move and the
slip joint 23 break away from the pin h".
So also during the rocking movement of this slide H³, the finger Hat such time
not being in line with the short arm of the transferrer, a finger c20, see Fig. 4, acts
against the upper end of a holding pawl T employed to engage the ratchet wheel of
the take up, thus temporarily suspending the operation of the take-up.
The particular construction of the ratchet or other wheels employed in the
measuring means, and the devices for actuating the measuring means, may be
variously modified, and instead we may employ as equivalents any usual speed
decreasing mechanism wherein a fast moving device or wheel, actuates another device
or wheel at a slower speed, so that the slow moving device, after it has passed over a
defined space will cause said slow moving device to operate suitable mechanism to
effect the operation of the filling changing mechanism.
Referring to Fig. 8, showing a detail of the measuring means it will be seen that
the lower ends of the legs 204 and 206 are beveled to a rather fine point, and as soon
as both openings in the two flanges with which each leg co-operates present their
edges in alignment the leg will drop effecting the operation of the transferrer and
without stopping the movement of the measuring means the said leg is instantly
raised before the lay again comes forward, and so it is impossible to operate the

page_text: ransferrer twice in immediate succession to make two successive changes of bobbin
arrier in the same shuttle.
In our invention we actuate the plurality of measuring means by a plurality of
awls which are practically controlled by a pattern surface, and said pawls are
ut into and out of position in accordance with the change from one to another shuttle
n the series of shifting shuttle boxes, and these pawls are connected with the shaft G¹,
noved by the movement of the shuttle box shifting lever, in turn controlled as to the
ime of its movement by the pattern surface.
The transferrer and its actuating parts constitute what is herein designated as filling
hanging mechanism, and instead of the particular transferrer and the means shown
for actuating it, any other suitable or well known filling changing mechanism may
be employed, and so also, instead of the particular filling feeder, any other suitable or
well known device may be employed.
This invention is not limited to the exact measuring means shown, nor to the
intermediate connections shown between the measuring means and the transferrer,
for it will be obvious to those skilled in the art that these devices might be variously
changed or modified by the exercise only of mechanical skill and not requiring
invention.
This invention is not limited to the particular mechanism shown intermediate the
measuring means and the transferrer, and instead of the devices thus far specifically
described, we may employ mechanism such as shown in Figs. 15 and 16.
In those figures the rod H50, which takes the place of the rod H5, is merely a
rocking rod, and it has a short arm H40 on which is pivoted at y a finger y',
connected at its lower end with a rod y², in turn connected with one arm of an elbow
lever y³, y, pivoted at 4 in a stand y depending from the breast beam, the arm yo
of said lever being extended under the arm 210 which is fully shown in Fig. 6, and
when either of the legs connected with said arm enter the registered openings in the
measuring means, the said lever y³, ye, will be moved to turn the finger.y', and put
it between the short arm 26* of the transferrer and the bunter before described
connected with the lay, the finger when so turned causing the transferrer to be
worked.
Fig. 18, shows a third modification, the lever y³ -y being reversed from the
position shown in Fig. 15 where pattern chain 700 operates arms 3 and through it
finger y is actuated.
