Improvements in or relating to Shuttle Changing Mechanism of
Looms for Weaving.
We, RANDOLPH CROMPTON, of 62, William Street, in the City and County of
Worcester, in the Commonwealth of Massachusetts, one of the United States of
America, Manufacturer, and HORACE WYMAN, of 20, Harvard Street, Worcester,
aforesaid, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to improve that class of loom wherein a spare
shuttle is placed automatically at the level of the race of the lay, to be thrown
through the shed after the filling has been exhausted or run off from the filling
carrier in the running shuttle-box to a predetermined amount.
Herein the lay is provided with a running shuttle box, it containing the shuttle
which is used to furnish filling for the cloth being woven, and cooperating with
this running shuttle-box is a spare shuttle feeder, which at the proper time supplies
a spare shuttle to the lay to take the place of the shuttle in the running shuttle
box, said spare shuttle feeder being normally held stationary in its inoperative
position at the loom side near the breast beam.
When the filling on the filling carrier in the running shuttle box indicates, from
breakage or otherwise, that the shuttle in the running shuttle box should be
changed, then the shuttle feeder previously held in its inoperative stationary
position, is automatically placed vertically in line with the running shuttle box, the
said shuttle feeder on its arrival in said vertical line, occupying its operative position
at the level of the race of the lay, the running shuttle-box having in the meantime
been put into its inoperative position, to enable the shuttle contained in it to
escape from the entirely open rear side of said shuttle box into a suitable receptacle
made for it and located at the loom side.
Herein the running shuttle box is carried by a shuttle-box rod, and the shuttle
feeder is carried by a lever, said rod and lever being operated by a lever set in
motion at the proper times by a shuttle box shifting mechanism, said lever being
so mounted on or with relation to said shuttle box rod or lever that said shuttle
feeder may remain in its normal inoperative position at the loom side while the
running shuttle box is in its operative position and its shuttle is working properly
to furnish filling for the cloth.
After the failure of the filling in the shuttle in the running shuttle box, the
filling fork is operated as the lay is going forward to put the shuttle box shifting
mechanism in position to be started at the next or second forward motion of the
lay.
During the back stroke of the lay following the forward stroke when the filling
fork was actuated, the running shuttle box received again the failed shuttle, and
as the lay starts forward on its second stroke the shuttle box lever of the box
mechanism is started and the box rod carrying the running shuttle box and the
lever carrying the shuttle feeder are started upwardly and the lever acting against
the underside of a finger attached to the loom side and directed upwardly toward

page_text: :
the lay is caused to move toward the advancing lay so that a downwardly
inclined finger carried by the lay and directed toward the front of the loom may
receive on it from the first finger the lever carrying the shuttle feeder, and the
shuttle box lever in the continuance of this movement while the lay is advancing
causes the lever carrying the shuttle feeder to pass outo the guide or finger carried
by the lay, and by the time that the lay completes its second forward beat the
moving shuttle box has been lifted substantially into its inoperative position, and
the shuttle feeder has been put partially under it, and before the lay reaches the
end of its second back stroke the running shuttle box is put fully into its inoperative
position, and the shuttle feeder is put into its operative position at the level of the
race of the lay.
During this second backward stroke of the lay the failed shuttle in the running
shuttle box then elevated in its inoperative position, is thrown from the open rear
side of said box into the failed shuttle receptacle, said shuttle passing over a plate
carried by the lay, which, when the said running shuttle box is in its operative
position, acts on the rear side of the shuttle box and aligns the shuttle with relation
to the faces of the dents of the reed.
As the lay reaches the end of its second backward stroke the picker stick acts to
throw the auxiliary or spare shuttle from said shuttle feeder onto the race of the
lay.
As the lay starts in its third forward stroke both shuttle boxes are empty, and
during this third movement of the lay the shuttle box lever is actuated to lower
the box rod from its engagement with the guide or finger of the lay, which during
the second back stroke of the lay locked the shuttle feeder firmly to the lay, the
lever carrying sàid feeder passing onto the guide or finger at the loom side, where
said lever is again held with the feeder in its inoperative position, and by the time
that the lay completes its third back stroke the running shuttle box is again in its
operative position at the level of the lay and the box shifting mechanism is at rest
with its lever in its normal position.
The binder cooperating with the shuttle being thrown from the running shuttle
box may either be carried by the front plate or wall of said shuttle box or the
binder may be pivoted upon the lay at the rear side of the slot therein in which
works the picker stick.
The loom is provided with suitable frame, breast beam, under or cam shaft,
toothed wheel thereon, toothed wheel on the crank or lay shaft which rotates
twice to one rotation of the cam shaft, pitmen connecting the crank shaft with the
lay, toothed wheel fast on the cam shaft, said wheel having two series of teeth
separated by spaces, a cam on the cam shaft having a cam groove at its side, a
stand secured to the loom side, a short shaft having suitable bearings supported by
said stand, a disc fast on one end of said shaft and provided with a crank pin,
a mutilated gear fast on said shaft and provided with a broad tooth, a sliding fork
on said short shaft, it having an annular groove and a leg provided with a tooth
said leg sliding in a groove of said gear to put the tooth into or out of line with
the teeth of a gear as the shaft is to be moved or left at rest, a link embracing said
crank pin, a shuttle box pivoted lever and to one end of which said link is jointed,
a second link jointed to said lever and fitting over a stud extended from a block
attached to or forming part of a shuttle box rod carrying at its upper end a running
shuttle box composed of a horizontal plate, a substantially vertical front wall having
at its upper edge an overhung lip, and provided with a binder acted on by a spring,
said spring pressing the running shuttle against a wall or aligning face rising from
the top of the lay and located parallel with the faces of the dents of the reed, said
face constituting a rear wall for the running shuttle box when in its operative
position at the level of the race of the lay.
The bottom plate of the running shuttle box is carried by rods guided by bearings
carried by the lay and rising from a cross arm at the upper end of the shuttle
box rod.
There is a lever pivoted on the block, and an auxiliary or spare shuttle feeder

page_text: carried at the upper end of said lever, said feeder having in its bottom an open
slot for the picker stick the outer side of said shuttle feeder having a binder or
spring held in place by a screw in an ear.
The lever has an open notch or bifurcated portion provided with an anti-
friction roller. An upwardly inclined guide or finger connected to the loom side
and extended toward the lay enters the bifurcated portion of the lever when the
shuttle feeder occupies its stationary inoperative position at the loom side, a spring
connected to a short arm of said lever and to the box rod acting at such time to
keep said lever and shuttle feeder in such position.
There is also provided a filling fork, a slide or carrier for same, a guide in which
it may be slid, a finger engaging a notch in the slide; a rock shaft mounted in
bearings under the breast beam, a spring on said shaft to normally press the slide
toward the lay, an arm attached to said rock shaft, a link, an elbow pivoted lever,
a second pivoted lever and moved by another lever said second lever having a
projection which enters the groove of the sliding fork.
There is a shelf on which may be laid a spare shuttle ready to be put into the
shuttle feeder.
A guide or guiding and locking finger attached to the lay and extended down-
wardly and forwardly towards the front of the loom, is provided.
Also a hammer or filling fork slide mover having a part adjustable.
The non adjustable part is forked at its upper end to leave two prongs one to
contact with the heel of the filling fork when the latter is not tipped about its
pivot pin by the contact of filling with it, the other prong entering a notch in the
stand in which the filling fork slide works, said latter part constituting a support
and a guide for the said filling fork slide mover, and preventing any lateral move-
ment thereof in the direction of movement of the length of the breast beam.
Adjusting the former part on the latter part provides for determining the
position of the said end piece with relation to the tail piece of the filling fork when
the latter is not tipped so that there need not be any particular lost motion between
the same.
The said end part has an ear extended therefrom which passes under the breast
beam and prevents the forked end of the filling fork slide mover from rising too
high. The slide mover has a pin which enters the groove of the cam, a binder
rock shaft having usual binder fingers to act on the binders in usual manner is
used.
A picker stick check pivoted on the lower side of the lay is acted on by a spring;
and a stop limits the movement of said check into the path of the picker stick.
A rocker iron attached to the lay rocker shaft is provided with a downturned
neck or elbow and grooved to receive the block or lower end of the box rod carrying
the ranning shuttle box, and outside said neck said iron has a face provided with a
lug and a hole and the picker shoe carrying the picker stick rests on this face, a leg
of said shoe entering the hole and the lug entering a slot in the said shoe.
Fitting the block into a groove crossing the axis of the lay rock shaft and
occupying a position below the face thereof greatly simplifies the construction and
makes a more durable means for guiding the box rod than when said guide has,
as heretofore, extended above said rocker iron.
Instead of the toothed wheel having the tooth fixed thereto, an equivalent device
consisting of a sliding fork may be used, and it has two legs, the second leg carrying
the tooth, the two teeth of said sliding fork being out of line one with the other,
so that when the said fork is moved in opposite directions by the lever first one and
then the other of the said teeth may be put into line with the teeth of the gear so
that after the one or other of the teeth has been engaged by one or the other of
the set of teeth of a wheel to start said gear in motion, that the tooth which was
engaged will be left at that side of the gear furthest from the said starting toothed
wheel and the started gear will not move until the fork is moved to put one or the
other of the said teeth into the said open space.
The end of the lay has an attached plate which has a connected bar and guide or

page_text: finger, also a plate with two guides for rods forming part of means for carrying the,
running shuttle box.
The bottom of the running shuttle box has a slot for the picker stick, the shuttle-
feeder has a slot for the picker stick; aud the lay has a slot for the picker stick.
In operation let it be assumed that the shuttle in the running shuttle box is in its
operative position, and that said shuttle is boing thrown regularly supplying the usual
warp, as the shed is made, with filling.
In this condition of the loom the shuttle feeder stands in its inoperative position
at the loom side, and the guide or finger stands in the bifurcated part of the lever
carrying the said feeder.
If the filling breaks, the shuttle leaving the running shuttle-box fails to leave
filling in the shed, and its absence in the shed as the lay goes forward fails to turn
the filling fork on its pivot in the slide and consequently the uppermost finger of the
hammer strikes the said fork and moves backwardly the slide in the stand, causing
said carrier acting on finger to turn the rock shaft and move the elbow lever causing
said lever entering a slot in another lever to move the lower end of said lever out-
wardly so that a projection carried by it and entering the groove of the sliding fork
moves said sliding fork outwardly away from the loom side, putting the one tooth
thereof into the path of movement of the teeth of the toothed wheel.
Just before the said teeth meet the said one tooth to start the gear and the shaft
in motion, the lay arrives at its back stroke and the running shuttle box has thrown
into it the failed shuttle.
Now as the lay starts forward on what will be called its second stroke, the shuttle
box shifting mechanism will be started by the teeth engaging the tooth which will
start and turn the gear it imparting to it a half rotation which will so move the
shuttle box lever as to lift the box rod carrying the running shuttle-box, and at the
same time the lever and the shuttle feeder is lifted in unison with it.
As the lever rises its lever acting on the underside of the guide or finger causes
said lever and shuttle feeder to move toward the advancing lay, and as this
forward movement of the lay is continued the slotted or notched part of the lever
passes onto the guide or locking finger connected with the lay, and by the time
that the lay reaches its forward position in said second stroke, the running
shuttle-box is nearly lifted into its inoperative position, and that the shuttle feeder
is nearly in position at the race of the lay, and as the lay starts back on this second
stroke the full upward movement of the shuttle box rod and the lever is completed,
so that as the lay goes back the failed shuttle in the running shuttle box is thrown
laterally out from the rear side of said box over the aligning plate fixed to and
extended above the race of the lay, it passing into the shuttle receiver and as the
latter reaches its second back stroke the picker stick acts, it entering the slot of
the said shuttle feeder and striking the spare shuttle throws it from the shuttle feeder
onto the raceway of the lay.
The shuttle box lever stands for a moment stationary with the shuttle feeder in
its operative position and the auxiliary shuttle-box in its inoperative position, this
happening when the teeth run out of mesh with the gear and for a period measured
by the untoothed space between the teeth, the tooth of the said gear during the
time that the said gear and the shaft are stationary, occupying a position next the
toothed wheel, so that when in the rotation of said wheel a tooth on said toothed
gear meets the tooth that the said toothed gear will be engaged and rotated turning
with it the shaft for a half rotation.
This second half rotation takes place during the third forward stroke of the lay,
at which time both the running shuttle box and the shuttle feeder are empty, and
and as the lay goes forward on this third stroke the shuttle box lever is turned to
lower the shuttle box rod and the pivoted lever carrying the said shuttle feeder,
which results in causing the said lever to slide off from the guiding and locking
finger which at the previous back stroke of the lay acted as a locking device to
positively hold the said shuttle-feeder in fixed relation to the lay, and lets it descend
onto the finger, leaving the said shuttle feeder in its inoperative position, with the

page_text: running shuttle box in its operative position, so that when the lay arrives at its
third back stroke the running shuttle box is in the proper position to receive in it
the shuttle which was thrown from the spare shuttle feeder across the lay at the end
of the second back stroke.
In this condition the loom is again ready to run so long as the filling remains
intact in the running shuttle, and the shuttle box lever remains in its proper
position.
.
The hammer for moving the filling fork slide is moved backwardly on the
absence of the filling in the shed, the said hammer deriving its motion from a
pin in the groove of the cam, the shape of said groove being such as to retain the
hammer in its forward position, with its end in engagement with the tail of the.
filling fork, thus keeping the said filling fork from returning into its normal
position until after the shuttle box rod has been moved sufficiently to put the
running shuttle box in its inoperative position and the spare shuttle feeder into its.
operative position, this being about as the lay is completing its second forward
stroke, at which time the cam permits the hammer to move and enable the
slide bar to again come into its normal position under the action of the
spring.
The returning of the filling fork slide or carrier into its normal position enables
said rock shaft, the finger being in engagement with the notched end of the slide,
to be turned in an opposite direction so as to move the levers in a direction
to force the fork toward the loom side and put the tooth out of line of movement of
the approaching teeth of the toothed gear thus leaving the mutilated gear at rest
with the shuttlebox and feeder.
The loom may have a shipper handle, to control shipper devices to apply or
disconnect the driving power, from the can shaft.
According to a modification the binder may be pivoted on a stud located at the
upper side of the lay at the rear side of the slot in which the picker stick works,
the face of said binder occupying a position substantially in the line of the faces of
the detents of the reed said binder being kept yieldingly in position by a binder
finger.
Improvements in or relating to Shuttle Changing Mechanism of
Looms for Weaving.
We, RANDOLPH CROMPTON, of 62, William Street, in the City and County of
Worcester, in the Commonwealth of Massachusetts, one of the United States of
America, Manufacturer, and HORACE WYMAN, of 22, Harvard Street, Worcester,
aforesaid, Manufacturer, 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 improve that class of loom wherein a spare
shuttle is placed automatically at the level of the race of the lay, to be thrown
through the shed after the filling has been exhausted or run off from the filling
carrier in the running shuttle box to a predetermined amount.
Herein the lay is provided with a running shuttle box, it containing the shuttle
which is used to furnish filling for the cloth being woven, and cooperating with this
running shuttle box is a spare shuttle feeder, which at the proper time supplies a

page_text: spare shuttle to the lay to take the place of the shuttle in the running shuttle box,
said spare shuttle-feeder being normally held stationary in its inoperative position
at the loom side near the breast beam.
When the filling on the filling carrier in the running shuttle-box indicates from
breakage or otherwise, that the shuttle in the running shuttle box should be
changed, then the shuttle-feeder previously held in its inoperative stationary
position, is automatically placed vertically in line with the running shuttle-box, the
said shuttle feeder on its arrival in said vertical line, occupying its operative position
at the level of the race of the lay, the running shuttle box, having in the meantime
been put into its inoperative position, to enable the shuttle contained in it to escape
from the entirely open rear side of the said shuttle-box into a suitable receptacle
made for it and located at the loom side.
Herein the running shuttle-box is carried by a shuttle-box rod, and the shuttle-
feeder is carried by lever, said rod and lever being operated by a lever set in
motion at the proper times by a shuttle box shifting mechanism, said lever being so
mounted on or with relation to said shuttle-box rod or lever that said shuttle-feeder
may remain in its normal inoperative position at the loom side while the running
shuttle box is in its operative position and its shuttle is working properly to furnish
filling for the cloth.
After the failure of the filling in the shuttle in the running shuttle-box, the filling
fork is operated as the lay is going forward to put the shuttle box shifting
mechanism in position to be started at the next or second forward motion of the
lay.
During the back stroke of the lay following the forward stroke when the filling
fork was actuated, the running shuttle-box received again the failed shuttle, and as
the lay starts forward on its second stroke the shuttle-box lever of the box-
mechanism is started and the box rod carrying the running shuttle-box, and the
lever carrying the shuttle feeder are started upwardly and the lever acting against
the underside of a finger attached to the loom side and directed upwardly toward
the lay is caused to move toward the advancing lay so that a downwardly inclined
finger carried by the lay and directed toward the front of the loom may receive on
it from the first finger the lever carrying the shuttle feeder, and the shuttle-box
lever in the continuance of this movement while the lay is advancing causes the
lever carrying the shuttle feeder to pass onto the guide or finger carried by the
lay, and by the time that the lay completes its second forward beat the moving
shuttle-box has been lifted substantially into its inoperative position, and the
shuttle-feeder has been put partially under it, and before the lay reaches the end of
its second back stroke the running shuttle-box is put fully into its inoperative
position, and the shuttle feeder is put into its operative position at the level of the
race of the lay.
During this second backward stroke of the lay the failed shuttle in the running
shuttle-box, then elevated in its inoperative position is thrown from the open rear
side of said box into the failed shuttle receptacle, said shuttle passing over a plate
carried by the lay, which, when the said running shuttle box is in its operative
position, acts on the rear side of the shuttle-box and aligns the shuttle with relation
to the faces of the dents of the reed.
As the lay reaches the end of its second backward stroke the picker stick acts to
throw the auxiliary or spare shuttle from said shuttle-feeder onto the race of the
lay.
As the lay starts in its third forward stroke both shuttle-boxes are empty, and
during this third movement of the lay the shuttle-box lever is actuated to lower
the box rod from its engagement with the guide or finger of the lay, which during
the second back stroke of the lay locked the shuttle-feeder firmly to the lay, the
lever carrying said feeder passing onto the guide or finger at the loom side where
said lever is again held with the feeder in its inoperative position, and by the time
that the lay completes its third back-stroke the running shuttle box is again in its

page_text: operative position at the level of the lay and the box shifting mechanism is at rest
with its lever in its normal position.
The binder cooperating with the shuttle being thrown from the running shuttle-
oox may either be carried by the front plate or wall of said shuttle box or the
binder may be pivoted upon the lay at the rear side of the slot therein in which
works the picker stick.

teetli 24, 25, separated by spaces; d³ is a cam on the cam shaft, said cain having a
cam groove at its side; B* is a stand secured to the loom side; es a short shaft
having suitable bearings supported by said stand; b¹ is a disc fast on one end of said
shaft and provided with a crank pin e; f is a mutilated gear fast on said shaft and
provided with a broad tooth 4; f³ is a sliding fork on shaft es, it having an annular

page_text: groove fxx and a leg provided with a tooth 3, said leg sliding in a groove of said
gear to put the tooth 3 into or out of line with the teeth of the gear G as the
shaft is to be moved or left at rest; e is a link embracing said crank pin; ³ a
shuttle-box lever pivoted at et, and to one end of which said link is jointed; e² is
a second link jointed to said lever and fitting over a stud 63 extended from a
block 22 attached to or forming part of a shuttle box rod De carrying at its upper
end a running shuttle-box D composed of a horizontal plate d a substantially
vertical front wall having at its upper edge an overhung lip d, and provided
with a binder d' acted on by a spring do, said spring pressing the running shuttle
against a wall or aligning face c rising from the top of the lay and located parallel
with the faces of the dents of the reed, said face constituting a rear wall for the
running shuttle-box when in its operative position at the level of the race of the
lay.
The bottom plate of the running shuttle box is carried by rods 610, 612, guided
by bearings carried by the lay and rising from across arm 6º at the upper end of the
shuttle box rod De.
h³ is a lever pivoted at ht on the block 22, and h is the auxiliary or spare shuttle-
feeder carried at the upper end of said lever, said feeder having in its bottom an open
slot h, see Fig. 11, for the picker stick C³, the outer side of said shuttle-feeder
having a binder or spring g held in place by a screw g¹ in an ear 30.
The lever h³ has an open notch or bifurcated portion he provided with an anti-
friction roller h¹². An upwardly inclined guide or finger hº connected to the
loom side and extended toward the lay enters the bifurcated portion of the
lever h³ when the shuttle feeder occupies its stationary inoperative position at
the loom side, see Fig. 2, on spring h30 connected to a short arm of said lever
and to the box rod De acting at such time to keep said lever and shuttle feeder in
such position.
c is a filling fork, c its slide or carrier ca guide in which it may be slid,
clo a finger engaging a notch in the slide c8; c12 a rock-shaft mounted in
bearings under the breast beam; c¹²* a spring on said shaft to normally press
the slide cs toward the lay; c¹³ an arm attached to said rock-shaft; c¹ a link; fan
elbow lever pivoted at 20; e¹² a second lever pivoted at e¹ and moved by lever (*,
said lever e¹ having a projection 26 which enters the groove f** of the sliding
fork f³.
g2 is a shelf on which may be laid a spare shuttle in order that it may be ready to
put into the shuttle feeder when required.
c is a guide or guiding and locking finger attached to the lay and extended
downwardly and forwardly towards the front of the loom.
di do is a hammer or filling fork slide mover, the part do being adjustable on or
with relation to the part d¹. The part do is forked at its upper end to leave two
prongs d¹ and d² (Figs. 4 & 6), the one 15 to contact with the heel 6 of the filling
fork c when the latter is not tipped about its pivot pin by the contact of filling
with it, the other prong d² entering a notch in the stand c in which the filling fork
slide works, said part d² constituting a support and a guide for the said filling fork
slide mover, and preventing any lateral movement thereof in the direction of
movement the length of the breast beam.
Adjusting the part do on the part 11 provides for determining the position of the
said end piece do with relation to the tail piece 6 of the filling fork when the latter
is not tipped so that there need not be any particular lost motion between the same.
The part do has an ear extended therefrom which passes under the breast beam
and prevents the forked end of the filling fork slide mover from rising too high. The
slide mover has a pin 66 which enters the groove of the cam d³, 29 represents a binder
rock-shaft having usual binder fingers 28 to act on the binders and d5* in usual
manner.
43 is a picker stick check pivoted on the lower side of the lay and acted on by a
spring 44; and 45 is a stop to limit the movement of the said check into the path
of movement of the picker stick.

page_text: The rocker iron he attached to the lay rocker shaft is provided with a down-
turned neck or elbow grooved at h³ to receive the block or lower end 22 of the
box-rod carrying the running shuttle-box, and outside said neck said iron has a
face g provided with a lug go and a hole g', and the picker shoe gs carrying the picker
stick rests on this face, a leg g of said shoe entering the hole g', and the lug g
entering a slot in the said shoe.
Fitting the block into a groove crossing the axis of the lay rock-shaft and
occupying a position below the face g5 greatly simplifies the construction and makes
a more durable means for guiding the box rod D6 than when said guide has, as
heretofore, extended above said rocker iron.
Instead of the toothed wheel f having the tooth 4 fixed thereto, an equivalent
device consisting of a sliding fork, such as represented in Fig. 19, may be used, it
differing from the sliding fork shown in Figs. 1 and 2, in that it has two legs, the
second leg carrying the tooth 4, the said teeth 3 and 4 of said sliding fork being out
of line one with the other, so that when the said fork is moved in opposite
directions by the lever e¹ first one and then the other of the said teeth may be put
into line with the teeth of the gear f, so that after the one or other of the teeth 3 or 4
has been engaged by one or the other of the set of teeth of the wheel G to start said
gear in motion, that the tooth which was engaged will be left at that side of the
gear f furthest from the toothed wheel G and the gear f will not be started until the
fork is moved to put one or the other of the said teeth into the said open space.
The end of the lay bas an attached plate 614 held in place by bolts 618 and screws 617,
and said plate has a connected bar 615 to which is attached the guide or finger c³.
Plate b has two guides 613, 613*, for the rods 610, 612 forming part of the means for
carrying the running shuttle-box.
The bottom of the running shuttle-box has a slot d for the picker stick, the shuttle
feeder has a slot h¹ for the picker stick; and the lay A3 has a slot 618 for the
picker stick.
In operation let it be assumed that the shuttle c¹ in the running shuttle-box D is
in its operative position, see Figs. 1 and 2 and that said shuttle is being thrown
regularly supplying the usual warp, as the shed is made, with filling.
In this condition of the loom the shuttle feeder / stands in its inoperative position
at the loom side, see Fig. 2, and the guide or finger stands in the bifurcated part
of the lever 3 carrying the said feeder.
If the filling breaks, the shuttle leaving the running shuttle-box fails to leave
filling in the shed, and its absence in the shed as the lay goes forward fails to turn
the filling fork c on its pivot in the slide 8, and consequently the uppermost
finger of the hammer strikes the said fork and moves backwardly the slide in
the stand c, causing said carrier acting on finger 10 to turn the rock shaft c¹² and
move the elbow lever f" in the direction of the arrow near it, causing said lever
entering a slot in the lever e¹² to move the lower end of said lever outwardly so that
the projection 26 carried by it and entering the groove of the sliding fork f³ moves
said sliding fork outwardly away from the loom side, putting the tooth 3 thereof
into the path of movement of the teeth 24 of the toothed wheel G.
Just before the teeth 24 meet the tooth 3 to start the gear f and the shaft es in
motion, the lay A³ arrives at its back stroke and the running shuttle box has
thrown into it the failed shuttle.
Now as the lay starts forward on what will be called its second stroke, the shuttle
box shifting mechanism will be started by the teeth 24 engaging the tooth 3 which
will start and turn the gear f, it imparting to it a half rotation which will so move
the shuttle-box-lever es as to lift the box-rod De carrying the running shuttle-box,
and at the same time the lever h³ and the shuttle feeder is lifted in unison
with it.
As the lever ³ rises its roller 12 acting on the under side of the guide or finger ho
causes said lever h³ and shuttle feeder to move toward the advancing lay, and as
this forward movement of the lay is continued the slotted or notched part of the
R

page_text: lever h³ passes onto the guide or locking finger c' connected with the lay, and by
the time that the lay reaches its forward position in said second stroke, the parts
are as represented in Fig. 3, where it will be seen that the running shuttle box is
nearly lifted into its inoperative position and that the shuttle-feeder is just coming
over into position at the race of the lay, and as the lay starts back on its second
stroke the full upward movement of the shuttle-box rod and the lever e³ is com-
pleted, so that as the lay goes back see Fig. 4 the failed shuttle in the running
shuttle-box is thrown laterally out from the rear side of said box over the aligning
plate c fixed to and extended above the race of the lay, it passing into the shuttle-
receiver c³ see Fig. 2, and as the latter reaches its second back stroke the picker
stick C³ acts, it entering the slot h¹ of the said shuttle feeder and striking the spare
shuttle throws it from the shuttle feeder onto the raceway of the lay.
The shuttle-box lever e³ stands for a moment stationary with the shuttle feeder
in its operative position and the auxiliary shuttle-box in its inoperative position, this
happening when the teeth 24 run out of mesh with the gear f and for a period
measured by the untoothed space between the teeth 24 and 25, the tooth 4 of the
gear during the time that the said gear fand the shaft e³ are stationary, occupying
a position next the toothed wheel G, so that when in rotation of said wheel the
tooth 25 on said toothed gear meets the tooth 4, that the said toothed gear of will
be engaged and rotated turning with it the shaft e' for a half rotation.
This second half rotation takes place during the third forward stroke of the lay,
at which time both the running shuttle-box and the shuttle-feeder as in Fig. 4 are
empty, and as the lay goes forward on this third stroke see Fig. 5 the lever e³ is
turned to lower the shuttle-box rod D6 and the lever h³ carrying the said shuttle-
feeder, which results in causing the said lever h³ to space off from the guiding and
locking finger c5, which at the previous back stroke of the lay acted as a locking
device to positively hold the said shuttle-feeder in fixed relation to the lay, and lets
it descend onto the finger ho, leaving the said shuttle feeder in its inoperative
position, as in Fig. 2, with the running shuttle-box in its operative position as in
said fig., so that when the lay arrives at its third back stroke see Fig. 6 the running
shuttle-box is in the proper position to receive in it the shuttle which was thrown
from the spare shuttle feeder across the lay at the end of the second back stroke.
In this condition the loom is again ready to run so long as the filling remains
intact in the running shuttle, and the shuttle-box lever e³ remains in its position
shown in Fig. 2.
In the operation of the loom it has been stated that the hammer for moving the
filling fork slide is moved backwardly on the absence of the filling in the shed, the
said hammer dd, deriving its motion from the pin 66 in the groove of the cam d³,
the shape of said groove being such as to retain the hammer in its forward position,
see Fig. 3, with its end d in engagement with the tail of the filling fork, thus
keeping the said filling fork from returning into its normal position until after the
shuttle box D has been moved sufficiently to put the running shuttle box in its
inoperative position, and the spare shuttle-feeder into its operative position, this
being about as the lay is completing its second forward stroke, at which time the
cam permits the hammer to move and enable the slide bar c³ to again come into its
normal position under the action of the spring c12.
The returning of the filling fork slide or carrier into its normal position enables
said rock-shaft, the finger co being in engagement with the notched end of the
slide, to be turned in an opposite direction so as to move the lever f and e¹² in a
direction to force the fork f³ toward the loom side and put the tooth 3 out of line
of movement of the approaching teeth 24 of the toothed gear G thus leaving the
mutilated rear fat rest with the shuttle box and feeder in the position Fig. 2.
The loom may and preferably will have a shipper handle, as H, see Fig. 14,
which may control any usual or belt shipper devices commonly employed to apply or
disconnect the driving power, as desired, from the cam shaft, said shipper handle
being held normally in its operative position by any usual or suitable notched slotted
plate as H¹.

page_text: The fast and loose pulley contrivances and the mechanism between it and the
shipper handle are not shown as the same may be of any suitable or usual construc-
tion, the shipper handle in this instance is used only when it is desired to stop the
loom for any purpose.
It is not used and controlled automatically for any purpose.
Referring to Figs. 21 and 22 a modification of this invention will be described;
in said figures the binder M may be pivoted on a stud M' located at the upper side
of the lay at the rear side of the slot 618 in which the picker stick C³ works, the face
of said binder occupying a position substantially in the line of the faces of the
detents of the reed 2, said binder being kept or held yieldingly in its said position
by a binder finger M carried in any usual manner, as by a rock-shaft 29 of usual
construction mounted under the beam of the lay.
Fig. 14 shows the binder finger working on the binder of the running shuttle-
box, but in the modification just described the binder will be at the rear side of the
lay, in other words it is immaterial at which side of the picker stick slot the binder
works, the operation will be substantially the same.
