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 the production of a novel loom wherein a shuttle
in a running shuttle box carried by the lay, after the failure of the filling therein,
may be automatically displaced or discharged from the lay and another shuttle having
filling may be supplied on the race of the lay, to take the place of the shuttle in
which the filling has failed, or which shuttle for any reason it is desired to replace
for another shuttle.
In this invention the lay has a shuttle box, designated as the running shuttle box,
it being provided at its front side with a binder and open at its rear side, said box
containing the shuttle which supplies filling for the cloth being woven, said binder
when said shuttle box is in its operative position pressing the shuttle in said running
shuttle box against an aligning surface carried by a guide casting having guide ways
in which the ends of the said running shuttle box slide up and down.
The operative position of the said running shuttle box is determined by a projection
carried by said box resting upon said guide casting, the weight of the running shuttle
box keeping it in its operative position.
Cooperating with this running shuttle box is an auxiliary shuttle box slotted at its
rear side to embrace said aligning surfaces when said auxiliary shuttle box is in its
operative position at the level of the race of the lay.
This auxiliary shuttle box has a binder and is carried by a shuttle box rod actuated
by any usual box motion mechanism containing preferably a lever.
This auxiliary shuttle box, it containing a spare or auxiliary shuttle, instead of
being carried constantly by the lay, is normally held stationary, in an inoperative
position at the loom side at or near the breast beam during the regular running of
the loom, by a holding device which is under the control of a filling fork and its
slide or carrier, the movement of said filling fork slide or carrier induced by the
absence of the weft in the shed, effecting the release of the auxiliary shuttle box,
that it may be moved by a suitable spring toward and to meet the lay at that forward
stroke thereof at which the absence of the filling in the shed caused the filling fork
slide to be moved.
As the lay is moved back after the operation of the filling fork slide and the release
of the holding device, the auxiliary shuttle box moves back with said lay, and in so
doing, the box rod of said auxiliary shuttle box actuates certain controlling devices,
which puts the box motion mechanism in condition to be started to lift the box rod
of the auxiliary shuttle box.
As the lay reaches its first back stroke after operation of the filling fork slide, the
failed shuttle is thrown back again into the running shuttle box, it yet occupying its
operative position at the level of the race of the lay, but as the lay starts forward on

page_text: its next or second forward stroke with the auxiliary shuttle box lying directly under
the running shuttle box, the box motion mechanism starts and acts to lift the box
rod and said auxiliary shuttle box, and about the time that the lay arrives at the end
of its second forward stroke or immediately thereafter the said auxiliary shuttle box
has arrived in its operative position at the level of the race of the lay, and in coming
into such position, it acting directly against the underside of said running shuttle
box puts it with its shuttle into its inoperative position above the level of the race of
the lay.
Lifting the running shuttle box in this way into its inoperative position above the
race of the lay removes the open rear side of said running shuttle box above the
slotted bar forming part of said glide casting, it constituting the rear wall for
the running shuttle box when in its operative position, so that as the lay travels
backwardly in its second back stroke with the running shuttle box elevated in
its inoperative position, the shuttle contained in said running shuttle box will
be thrown laterally therefrom onto a suitable shelf prepared to receive it.
The bar of the guide casting, referred to, is slotted for the passage therethrough
of the picker employed to throw not only the shuttle from the running shuttle box,
but from the auxiliary shuttle box.
As the lay is moving in or arrives at the end of its second back stroke referred to,
the picker acts on the spare shuttle in the auxiliary shuttle box then in its operative
position at the level of the race of the lay, and throws said auxiliary shuttle from
said auxiliary shuttle box onto and across the lay into the usual box at the opposite
end of the lay.
As the lay goes forward in its third stroke, both shuttle boxes being then empty,
the box motion mechanism is again moved to effect the lowering of the box rod
carrying the auxiliary shuttle box, and as the lay arrives at the end of its third
forward stroke, the holding device again acts to engage and retain the auxiliary
shuttle box in its stationary inoperative position, where it may be again provided with
a spare shuttle.
At the end of this third forward stroke, the running shuttle box has descended
into its operative position, and as the lay travels back in its third backward stroke,
the shuttle previously thrown from the auxiliary shuttle box across the lay is picked
hack into the running shuttle box, and it continues to be thrown from said running
shuttle box until the shuttle is again to be changed.
The loom frame, the breast beam, the lay having a raceway, the guide casting
connected to the lay by suitable bolts and extended from one end of the lay, the
picker guide rod upon which is mounted to slide the picker, said picker entering a
slot in the guide casting; the crank shaft, the connecting rods operated thereby and
suitably attached to the lay; the cam or other shaft rotated once for each two
rotations of the crank shaft through suitable gears, and attached to said shafts at the
opposite side of the frame; the filling fork pivotally mounted on a filling fork slide,
suitably supported in a guideway, located on the breast beam at the right hand end
of the loom; the finger engaging said filling fork slide or carrier and attached to a
rocker shaft, having an extended arm; the cam on the cam shaft; the lever actuated
by said can and carrying a hammer, to engage the tail of the filling fork and move
it and its slide backwardly toward the front of breast beam, to turn said rock shaft
and its arm whenever the filling fork shall not have been tilted by or through the
presence of filling in the shed; and the picking stick and its operating means may
be all as in usual looins.
The guide casting is provided with guide ways to guide the opposite ends of the
running shuttle box.
This running shuttle box is open at its rear side for the discharge of the shuttle in
'said box when the box occupies its inoperative position.
This running shuttle-box has pivoted to it a binder acted upon by spring, said box
also having attached to its upper side a suitable lip or projection which contacts with
the guide casting when the said running shuttle box is in its operative position, said
projections serving to position the said shuttle box at the level of the race

page_text: of the lay, the weight of the shuttle box causing it to maintain its operative
position.
A part of the guide casting is a bar, slotted for the movement of the picker, and
this bar above and below said slot is provided with suitable projections constituting an
aligning surface the face of said projections lying in the vertical plane of the detents
of the reed, said aligning surface receiving against it not only the rear side of the
shuttle in the running shuttle box, but also the rear side of the shuttle in the
auxiliary shuttle box, positioning whichever shuttle is to be thrown squarely and
properly with relation to the dents of the reeds, so that said shuttle when thrown may
traverse the race of the lay in a proper line.
The lay fulcrum shaft has mounted upon it loosely the lower end of a stand, it
having suitable guideways in which is mounted to slide the box rod carrying the
auxiliary shuttle hox, the latter having a forked guide which spans and slides on a
portion of said stand, it preventing any twisting or rocking movement of the
box rod.
The guideway or some other suitable portion of the stand has a projection which is
adapted to be engaged by a holding device as a latch pivoted on a suitable stand at
the loom side, said holding device, acted upon by a suitable spring, being normally
kept depressed on the end of a finger or projection extended from the arm herein
before described, so that as said arm is moved by the rock shaft as when the filling
fork is moved backwardly due to fault in the filling, the said holding device will be
raised, to thus release the stand and enable a suitable device as a spring, connected
with an arm extended from the base of the stand, to operate and move said stand and
box rod quickly toward the advancing lay.
The box rod carrying the auxiliary shuttle box is wholly detached from the running
shuttle box and from the lay when the running shuttle is being thrown from the
running shuttle box and is supplying filling to the cloth and the lay is moving
regularly.
The auxiliary shuttle box normally occupies an inoperative position, and at such
time it is held stationary at the loom side by the holding device, and it supports a
spare shuttle which is to be supplied to the race of the lay when the filling fails in
the shuttle of the running shuttle box.
The auxiliary shuttle box, on the failure of the filling in the running shuttle box,
must meet and move with the lay, and also be actuated to put its spare shuttle at the
level of the race of the lay instead of the running shuttle, thus:
The box rod is provided with a collared stud which receives on it a hub at the end
of a link jointed to the end of a pivotted lever, the opposite end of said lever having
adjustably attached to it the upper end of a link, the lower end of said link fitting
a crank on a disc, fast on a short shaft, having its bearings located in a yielding
box.
The short shaft has fast on it a mutilated gear having say two series of teeth
separated one from the other by a space, one or other of said spaces being filled alter-
nately by a tooth, each carried by a suitable arin, of a sliding toothed gear, said gear
having an annular groove at one end.
The mutilated gear and the shaft derive intermittent movement to lower one end
of the lever leaving it temporarily in its lowered position, and then to raise said
lever to its normal position by other teeth from a toothed wheel fast on the
continuously rotating cam shaft.
Other usual or suitable shuttle box shifting mechanism may be employed.
The movement of the sliding toothed gear, in one or the other direction,
determines when the short shaft shall be started and moved for a semi-rotation ;
effected by controlling mechanism, such as a pivoted lever having at its lower end a
suitable roller or other stud which enters an annular groove in the said gear, said
lever having a slot entered by one end of a pivotted elbow lever, said roller being
moved by devices, moving with the shuttle box rod and its guide after the said
guide shall have been released by the holding device, the filling having failed in the
shuttle of the running shuttle box.
"

page_text: The pivoted lever is retained in either of its two extreme positions, in which it may
be left by the lever by or through the action of a spring connected at one end to said
lever and at its opposite end to a portion of the stand, secured to the loom
side.
The auxiliary shuttle box has depending from its lower side suitable arms which
receive a rod on which is pivotally mounted arms of a plate or binder, which
acts on the outer side of the spare shuttle to be delivered by said auxiliary shuttle box
against the aligning face of the lay, and this plate or binder is normally pressed
toward the side of the shuttle resting upon it by means of il suitable
spring.
One of the arms of the plate or binder is extended below the rod, and has jointed
to it a depending leg, said leg, when the plate or binder is in its closed position,
presenting its lower end below the notched top of a leg rest fast on and moving with
the lay rocker shaft, said leg resting at such time against the bottom of a slot made
in an extension from the guide, a spring connected with said leg, normally keeping it
against the shoulder at the bottom of the said slot.
The box rod has attached to it and extended from it a suitable rod or finger, having
a spring so that it may yield somewhat if desired, and slide in a part of the collar
fixed on the box rod.
The stand has attached to it a second rod or finger.
The movements of the auxiliary shuttle box backward and forward with the lay,
after the failure of the filling in the running shuttle box, operate at proper times
to automatically start the shuttle box shifting mechanism, and effect the rise, and
the fall of the said auxiliary shuttle box.
When the auxiliary shuttle box is in its normal inoperative position, a space of the
mutilated gear stands next another gear, and this space, before the said box can be
raised, must be filled by the tooth of the said sliding toothed gear, and the
mutilated gear will stop after having made a semi-rotation because of the absence
of a tooth from the opposite space in the mutilated gear, and this latter gear
may be given instantly a second rotation by putting the absent tooth of the sliding
tooth gear into the space of the mutilated gear in position to be engaged by a tooth
of the gear next to it, but said mutilated gear will have but a semi-rotation imparted
to it, and will stop as soon as the space in the said gear, which is unoccupied by
the tooth of the sliding toothed gear, again comes into position next the gear
next it.
The shuttle is picked only as the lay is near its back stroke, and the hammer for
actuating the filling fork is moved only at each second forward beat of the lay, and
when said hammer is once moved to actuate the filling fork, it does not come back
into its normal position until after the stroke of the lay next following that stroke at
which the filling fork slide or carrier was moved to operate the arm to release the
auxiliary shuttle box.
Let it be supposed that the filling fails, as the picker stick has just thrown
shuttle from the running-shuttle-box, and as the lay reaches its forward stroke, the
filling fork not finding the filling in the shed is actuated to move the filling fork
slides and turns the holding device to release the auxiliary shuttle box so that it
may move to meet the lay and put its box under the running shuttle box and then
follow back with the lay in such condition and during this backward movement of
the lay, the failed shuttle is picked or thrown back into the running box, it yet being
in its operative position, and also during the latter part of this back stroke, a finger
.carried by the box rod meets the lever of the controlling mechanism and moves a
tooth of the sliding tooth gear into the space of the mutilated gear immediately in
front of one of the sets of teeth of the adjacent gear, so that as said teeth meet the said
tooth, which it does during the next forward movement of the lay, said teeth act to turn
the said mutilated gear and raise the auxiliary shuttle box into its operative position
at the level of the race of the lay, as the lay completes its forward stroke.
The auxiliary shuttle box commences to rise on the second forward stroke of the
lay, it starting to rise just as soon as the one series of teeth meet the other tooth,

page_text: and after about a quarter turn of the said mutilated gear, the other tooth at such
time not being engaged with the tooth of the series the lay in its second forward
stroke causes an arm to meet the rear side of a lever as already stated moving it to
slide the tooth out of the space in the mutilated gear then occupied by it, and put
another tooth into the opposite space in said gear.
The set of teeth which engaged the single tooth and started the one gear running
out of mesh with the teeth of the other gear leaving that gear at rest with its tooth
next its other adjacent gear and in the space between said set of teeth close to that
end of the space next the same, which just operate 1, the mutilated gear remaining at
rest while the lay comes back the second time because the elevation of the auxiliary
shuttle box, as described, lifted the art out of the range of movement of its
inoperative lever and consequently the two shuttle boxes at the end of this second
backward stroke of the lay, after the failure of the filling, occupy the required
position.
The failed shuttle during this second backward stroke of the lay is thrown from
the running shuttle box on to the receiver and it is also during this second backward
stroke of the lay that the shuttle in the auxiliary shuttle box, then at the level of
the race of the lay, is picked therefrom across the lay, so that in this last position,
both boxes are empty.
While the lay is moving in its second backward stroke, as described, an untoothed
part of the adjacent gear is passing the tooth then in working position and conse-
quently the mutilated gear is not moved.
But as soon as the lay reaches the end of its second back stroke, and starts in its
third forward stroke, one of the sets of teeth come iminediately into position to
engage the tooth then in position as stated and consequently the mutilated gear is
rotated during the third forward stroke of the lay, it moving the pivotted lever and
lowering the auxiliary shuttle box, so that at the time the lay reaches the end of its
third forward stroke, the parts are in such a position that the auxiliary shuttle box
being then in its inoperative position, and the running shuttle box in its operative
position, so that as the lay next goes back, at which time the picking takes place
again, the shuttle is made to enter the running box.
Prior to the third backward movement of the lay after the failure of the filling, the
filling fork is permitted to assume its normal position, so that the holding device or
arm may act to hold the auxiliary shuttle box so that it cannot move with the lay,
and consequently the operating arm cannot work and the space for the teeth being
open next to the said adjacent gear, the mutilated gear remains at rest.
When the auxiliary shuttle box is raised from the position at the end of the first
back stroke into the position at the end of the second forward stroke the leg was
lifted with it into such position that the lower end of said leg came above and in line
with the notch at the upper end of the leg rest referred to, and the spring immediately
moved said leg onto and so that it was sustained by the leg rest.
When, however, the auxiliary shuttle box was depressed, as from the position at
the end of the second back stroke into the position at the end of the third forward
stroke the leg was not free to descend because it was supported on the rest and
consequently the plate or binder was, during this lowering of the auxiliary shuttle
box put in positions, so that said plate or binder passed underneath the lowermost
shuttle in the magazine, suitably supported by a bolt at the loom side.
When the auxiliary shuttle box was being moved with the lay and depressed from
the position it occupies at the end of the second back stroke into the normal or
inoperative position the projection from the stand passed under the hooked end of
the holder said holder engaging said projection and keeping the said stand and
auxiliary shuttle box from again going back with the lay, and after locking the stand
the further movement backward of the lay with its leg rest removed said leg rest from
the end of the leg, thus releasing said leg, so that the spring on the shaft acted to
elevate the plate or binder so that it, in its closing movement acted against one side
of the lowerinost shuttle in the magazine, and transferred said shuttle from said
magazine automatically into position in the auxiliary shuttle box.
"

page_text: In order that the aligning surface referred to may operate to align the side of
the shuttle held in the auxiliary box, so that said shuttle may be correctly thrown
therefrom, the said auxiliary shuttle box is provided at its rear side with a series of
notches, cut into the top and bottom of the said auxiliary box for a distance
beyond the lips thereof, so that said lips may enter freely the spaces between the
aligning surfaces and the said notches may embrace freely said aligning surfaces.
The inner side of the plate or binder will preferably be provided with some suitable
non-metallic material such for instance as leather or rubber.
When the filling fails in the running shuttle box its absence is detected in the
shed while the lay is moving forward and while the shuttle containing the failed
filling is in the box at the opposite end of the lay, and at the next backward stroke
of the lay the shuttle having the failed filling is thrown back again into the running
shuttle box, this being done preparatory to putting the auxiliary shuttle box with its
spare shuttle into its operative position at the level of the race of the lay.
The loom side is provided with a shuttle stop it occupying a position opposite
the outermost open end of the auxiliary shuttle box so that said shuttle cannot
by any accident get out of proper position in the said shuttle box so that its
ends will strike any part of the lay as the spare shuttle is being put into position to
be thrown onto the lay.

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, afore-
said, 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 the production of a novel loom, wherein a shuttle
in a running shuttle box, carried by the lay, after the failure of the filling therein,
may be automatically displaced or discharged from the lay and another shuttle
having filling may be supplied on the race of the lay, to take the place of the shuttle
in which the filling has failed, or which shuttle for any reason it is desired to replace
for another shuttle.
In this invention the lay has a shuttle box, designated as the running shuttle box,
it being provided at its front side with a binder and open at its rear side, said box
containing the shuttle which supplies filling for the cloth being woven, said binder
when said shuttle box is in its operative position pressing the shuttle in said running
shuttle box against an aligning surface carried by a guide casting having.guide ways
in which the ends of the said running shuttle box slide up and down.
The operative position of the said running shuttle box is determined by a projection
carried by said box resting upon said guide casting, the weight of the running shuttle
box keeping it in its operative position.
Co-operating with this running shuttle box is an auxiliary shuttle box slotted at its
rear side to embrace said aligning surfaces when said auxiliary shuttle box is in its
operative position at the level of the race of the lay.

page_text: This auxiliary shuttle box has a binder and is carried by a shuttle box rod actuated
by any usual box motion mechanism containing preferably a lever.
This auxiliary shuttle box, it containing a spare or auxiliary shuttle, instead of being
carried constantly by the lay, is normally held stationary, in an inoperative position
at the loom side at or near the breast beam during the regular running of the loom,
by a holding device which is under the control of a filling fork and its slide or
carrier, the movement of said filling fork slide or carrier induced by the absence of
the weft in the shed, effecting the release of the auxiliary shuttle box, that it may be
moved by a suitable spring toward and to meet the lay at that forward stroke thereof
at which the absence of the filling in the shed caused the filling fork slide to be
moved.
As the lay is moved back after the operation of the filling fork slide and the
release of the holding device, the auxiliary shuttle box moves back with said lay,
and in so doing, the box rod of said auxiliary shuttle box actuates certain con-
trolling devices, which puts the box motion mechanism in condition to be started
to lift the box rod of the auxiliary shuttle box.
As the lay reaches its first back stroke after the operation of the filling fork
slide, the failed shuttle is thrown back again into the running shuttle box, it
yet occupying its operative position at the level of the race of the lay, but as
the lay starts forward on its next or second forward stroke with the auxiliary shuttle
box lying directly under the running shuttle box, the box motion mechanism starts
and acts to lift the box rod and said auxiliary shuttle box, and about the time that
the lay arrives at the end of its second forward stroke, or immediately thereafter the
said auxiliary shuttle box has arrived in its operative position at the level of the race
of the lay, and in coming into such position, it acting directly against the underside
of said running shuttle box, puts it with its shuttle into its inoperative position above
the level of the race of the lay.
Lifting the running shuttle box in this way into its inoperative position above
the race of the lay removes the open rear side of said running shuttle box above the
slotted bar forming part of said guide casting, it constituting the rear wall for the
running shuttle box when in its operative position, so that as the lay travels back-
wardly in its second back stroke with the running shuttle box elevated in its
inoperative position, the shuttle contained in said running shuttle box will be thrown
laterally therefrom on to a suitable shelf prepared to receive it.
The bar of the guide casting, referred to, is slotted for the passage therethrough
of the picker employed to throw not only the shuttle from the running shuttle box,
but from the auxiliary shuttle box.
As the lay is moving in or arrives at the end of its second back stroke referred to,
the picker acts on the spare shuttle in the auxiliary shuttle box then in its operative
position at the level of the race of the lay, and throws said auxiliary shuttle from said
auxiliary shuttle box onto and across the lay into the usual box at the opposite end
of the lay.
As the lay goes forward in its third stroke both shuttle boxes being then empty,
the box motion mechanism is again moved to effect the lowering of the box rod
carrying the auxiliary shuttle box, and as the lay arrives at the end of its third
forward stroke, the holding device again acts to engage and retain the auxiliary
shuttle box in its stationary inoperative position, where it may be again provided
with a spare shuttle.
At the end of this third forward stroke, the running shuttle box has descended
into its operative position, and as the lay travels back in its third backward stroke,
the shuttle previously thrown from the auxiliary shuttle box across the lay is picked
back into the running shuttle box, and it continues to be thrown from said running
shuttle box until the shuttle is again to be changed.

The loom frame A, the breast beam A¹, the lay A2 having a raceway A³, the guide
casting A+ connected to the lay by suitable bolts and extended from one end of the
lay, as represented in Figs. 12 and 13, the picker guide rod A5 upon which is mounted
to slide the picker Aº, shown by dotted lines in Fig. 2 and full lines in Fig. 12, said
picker entering a slot A7 in the guide casting; the crank shaft B, the connecting
rods B¹ operated thereby and suitably attached to the lay; the cam or other shaft B2
rotated once for each two rotations of the crank shaft through suitable gears B³ and
B4, and attached to said shafts at the opposite side of the frame; the filling fork B5
pivotally mounted on a filling fork slide B, suitably supported in a guideway B7,
located on the breast beam at the right hand end of the loom; the finger B8 engaging
the said filling fork slide or carrier and attached to a rocker shaft B, having an
extending arm B10, the cam C on the cam shaft: the lever C¹ actuated by said
cam and carrying a hammer c², to engage the tail of the filling fork and move
it and its slide backwardly toward the front of the breast beam, to turn said rock

page_text: shaft 19 and its arm B10 whenever the filling fork shall not have been tilted by or
through the presence of filling in the shed; and the picking stick C³ and its
operating means are and may be all as in usual looms so not need be herein
further described.
The guide casting A+ is provided with guideways a20 to guide that opposite ends a
and a of the running shuttle box, shown detached in Fig. 16.
This running shuttle box is open at its rear side sufficiently to afford ample space
for the discharge-therethrough of the shuttle in said box when the box occupies its
inoperative position above the aligning face to be referred to, of the said guide
casting.
This running shuttle box has pivoted to it at a21 a binder a³ acted upon by any
usual or suitable spring a, said box also having attached to its upper side a suitabe
lip or projection at which contracts with the guide casting when the said running
shuttle box is in its operative position, said projections serving to position the said
shuttle box at the level of the race of the lay, the weight of the shuttle box causing
it to maintain its operative position.
A part of the guide casting is a bar a³, and it is slotted at AT for the movement of
the picker referred to, and this bar above and below said slot is provided with suitable
projections W W₁, they constituting an aligning surface, the face of said projections
lying in the vertical plane of the detents w* of the reed, said aligning surface
receiving against it not only the rear side of the shuttle in the running shuttle box
but also the rear side of the shuttle in the auxiliary shuttle box, said aligning
surface positioning whichever shuttle is to be thrown squarely and properly with
relation to the dents of the reeds, so that said shuttle when thrown may traverse the
race of the lay in a proper line.
The lay fulcrum shaft D2 has mounted upon it loosely the lower end of a stand D³
it having suitable guideways D and D in which is mounted to slide the box rod Do
carrying the auxiliary shuttle box e, the latter having, as herein represented a forked
guide D7 which spans and slides on a portion of said stand D8, it preventing any
twisting or rocking movement of the box rod.
The guideway 14 or some other suitable portion of the stand has a projection D8
which is adapted to be engaged by a holding device d*, shown as a latch pivotted at d¹
on a suitable stand d², located at the loom side, said holding device, acted upon
by a suitable spring d³, being normally kept depressed on the end of a finger or
projection 2, see Fig. 2, extended from the arm B10 herein before described, so that as
said arm is moved by the rock shaft, Bº, as when the filling fork is moved backwardly
due to fault in the filling, the said holding device will be raised, to thus release the
stand and enable a suitable device as a spring do, connected with an arm d extended
from the base of the stand D³, to operate and move said stand and box rod quickly
toward the advancing day.
The box rod D6 carrying the auxiliary shuttle box e, is wholly detached from the
running shuttle box, and from the lay when the running shuttle is being thrown
from the running shuttle box and is supplying filling to the cloth and the lay is
moving regularly.
The auxiliary shuttle box normally occupies an inoperative position, as shown
in Figs. 2 and 6, and at such time it is held stationary at the loom side. by the
holding device dx, and it supports a spare shuttle which is to be supplied to the race
of the lay when the filling fails in the shuttle of the ruuning shuttle box.
The auxiliary shuttle box, on the failure of the filling in the running shuttle
hox, must meet and move with the lay, and also be actuated to put its spare
shuttle at the level of the race of the lay instead of the running shuttle, and to
do this there has been provided means designated under the term of "shuttle
box actuating means which will now be described.
The box rod is provided with a collared stud e¹ which receives on it a hub at the
end of a link e², said link being in turn suitably jointed to the end of a lever e³ having
its fulcrum at et, the opposite end of said lever having adjustably attached to it the
B

page_text: upper end of a link es, the lower end of said link fitting a crank eª on a disc e³, fast
on a short shaft es, having its bearings e located in a yielding box e¹0.
The shaft es has fast on it a mutilated gear f, herein shewn as having two series of
teeth, six teeth in each series, each series being separated one from the other by a
space, one or the other of said spaces being filled alternately by a tooth 3, or 4, each
carried by a suitable arm as f, or f², of a sliding toothed gear f³, said gear having an
annular groove at one end.
The mutilated gearf and the shaft es derive intermittent movement sufficiently to
lower the left hand end of the lever e³, Fig. 2, leaving it temporarily in its lowered
position and then to raise said lever into the position Fig. 2, its normal position by
or through the successive action of the teeth 5, 6, shown in two groups extended from
a toothed wheel G.fast on the continuously rotating shaft B².
Instead of the particular shuttle box mechanism just referred to, any other usual
or suitable shuttle box shifting mechanism.may be employed.
The movement of the sliding toothed gear f³, in one or the other direction,
determines when the shaft es shall be started and moved for a semi-rotation; and the
.movement of this gear is effected by controlling mechanism, herein represented as a
lever e¹² pivotted at e¹, and having at its lower end a suitable roller or other stud n10,
see Fig. 2, which enters the annular groove in the said gear, said lever e¹2 having as
..herein represented a slot which is entered by one end of an elbow lever fe pivotted
at e, said roller being moved by devices to be. hereinafter described, said devices
...moving with the shuttle box rod.and its guide D³.after the said guide shall have been
released by the holding device, the filling having failed in the shuttle of the running
shuttle box.
The lever e2 is retained in either of its two extreme positions, in which it may be
left by the lever fo, by or through the action of a spring f10 connected at one end to
said lever and. at its opposite.end to a portion f20 of the stand e120, secured to the
.. loom side.
**
The auxiliary shuttle box has depending from its lower side suitable.arms which
receive a rod h¹ on which are pivotally mounted the.arms 22 of a plate or binder h²,
which acts on the outer side of the spare shuttle to be delivered by said auxiliary
shuttle box against the aligning face of the lay, and this plate or binder is normally
-pressed toward the side of the shuttle resting upon it. by means of a suitable spiral
,spring h30, see Fig. 1, surrounding the shaft h, the opposite ends of the said spring
..bearing one upon the auxiliary shuttle box, and the other against the said plate or
'binder.
One of the arms 2 of the plate or binder h² is extended..as at 3 below the rod. h¹,
..and has jointed to it at ht a depending leg 5, said leg; when the, plate or binder is
in its closed position, see Fig..2, presenting its loweriend below the notched top of a
leg rest fast on and moving with the lay rocker shaft D², said leg resting at such
.time against the bottom of: a slot made in an extension h. from the stand D³ a
spring he shown in Figure.2, connected with said leg, normally keeping it against the
shoulder at. the bottom of, the said slot.
"The box rod De has attached to it and extended backwardly from it, a suitable rod
..or.finger g, see Figures 2 and 4, said finger being surrounded by a spring. 930, so that
it may yield somewhat if desired, and slide in a part of the collar fixed on the box
rod by a suitable screw ɖ60.

"
The stand D has attached to it and extended backwardly therefrom a second rod
or finger gx.
. Herein the movements of the auxiliary shuttle box backward and forward with the
lay, after the failure.of.the filling in the running shuttle box, operates. at proper
times, as will be described, to automatically start the shuttle box shifting.mechanism,
and effect simultaneously and quickly the rise, and at the proper period thereafter,
the fall of the said auxiliary shuttle box.
When the auxiliary. shuttle box is in its. normal inoperative position, a space of
the gear stands next the gear G, and this space, before the said box can be..raised,
must be filled by the tooth 4 of the gear and the gear f will stop after having

page_text: made a semi-rotation because of the absence of the tooth 3 from the opposite space in
the gear f, and this gear f may be given instantly a second rotation by putting the
tooth 3 of the sliding gear f³ into the space of the gear fin position to be engaged by
the teeth 5 of the gear G, but said gear will have but a semi rotation imparted to it,
and will stop as soon as the space in the said gear, which is unoccupied by the tooth 4,
again comes into position next the gear G.
The shuttle is picked only as the lay is near its back stroke, and the hammer c² for
actuating the filling fork is moved only at each second forward beat of the lay, and
when said hammer is once moved to actuate the filling fork, it does not come back
into its normal position until after the stroke of the lay next following that stroke at
which the filling fork slide or carrier was moved to operate the holding a to release
the auxiliary shuttle box.
Referring to Fig. 2, it shows the parts in the position they will occupy when the
loom is running regularly. The lay is shown in its backward position, and in such
position let it be assumed that the picker stick at the left hand end of the loom has
just picked or thrown the shuttle from the running shuttle box.
At this flight of the shuttle through the shed, let it be supposed that the filling
fails, and consequently, as the lay reaches its forward stroke, the filling fork not
finding the filling in the shed is actuated to move the filling fork slide and turns the
holding device d* to release the auxiliary shuttle box so that it may move to meet
the lay and put its box under the running shuttle box and then follow back with the
lay in such condition, and during this backward movement of the lay, the failed
shuttle is picked or thrown back into the running box, it yet being in its operative.
position, and also during the latter part of this back stroke, the finger g carried by
the box rod meets the lever fo of the controlling mechanism and moves the tooth 4
of the gear f³ into the space of the mutilated gear f, immediately in front of one of
the sets of teeth d of the gear G so that as said teeth meet the teeth 4, which it does
during the next forward movement of the lay, said teeth act to turn the said gear f
and raise the auxiliary shuttle-box into its operative position at the level of the race
of the lay, it moving into such position-see Fig. 8, as the lay completes its forward
stroke.
The auxiliary shuttle box commences to rise on the second forward stroke of the
lay, it being the stroke following that stroke when the filling failed, it starting to rise
just as soon as the series of teeth 5 meet the tooth 4, and after about a quarter turn
of the gear f, the tooth 4 at such time not being engaged with the tooth 5, the lay in
its second forward stroke causes the army to meet the rear side of the lever f", thus
moving it to slide the tooth 4 out of the space in the gear ƒ then occupied by it, and
put the tooth 3 into the opposite space in said gear.
The set of teeth 5 which engaged the tooth 4 and started the gear f¹ running out
of mesh with the teeth of the gear f, leaving that gear at rest with its tooth 3 next
the gear G and in the space between said teeth 5, close to that end of the space next
the teeth 5, which just operated, the said gear f remaining at rest while the lay
comes back the second time because the elevation of the auxiliary shuttle box, as
described, lifted the arm g out of the range of movement of the lever f, and conse-
quently the two shuttle boxes at the end of this second backward stroke of the lay,'
after the failure of the filling, occupy the position shown in Figure 9.
The failed shuttle during this second backward stroke of the lay is thrown
from the running shuttle box onto the receiver m, and it is also during this second
backward stroke of the lay that the shuttle in the auxiliary shuttle box, then at the
level of the race of the lay, is picked therefrom across the lay, so that in the position
Figure 9, both boxes are empty.
While the lay is moving in its second backward stroke, as described, an untoothed
part of the gear G is passing the tooth 3 then in working position, and consequently
the gear is not moved.
But as soon as the lay reaches the end of its second back stroke, and starts in its
third forward stroke, one of the sets of teeth 5 come immediately into position to
}
و.

page_text: engage the tooth 3 then in position as stated, and consequently the gear f is rotated
during the third forward stroke of the lay, it moving the lever and lowering the
auxiliary shuttle box, so that at the time the lay reaches the end of its third forward
stroke, the parts are in the position Figure 10, the auxilary shuttle box being then
in its inoperative position, and the running shuttle box in its operative position, so
that as the lay next goes back, at which time the picking takes place again, the
shuttle is made to enter the running box.
Prior to the third backward movement of the lay after the failure of the
filling, the filling fork is permitted to assume its normal position, so that the
arm dx may act to hold the auxiliary shuttle box so that it cannot move with
the lay, and consequently the arm g cannot work and the space for the teeth 4 being
open next to the said gear G, the gear f remains at rest.
When the auxiliary shuttle box is raised from the position Figure 7 into
the position Figure 8, the leg h³ was lifted with it into such position that the lower
end of said leg came above and in line with the notch at the upper end of the leg
rest h, referred to, and the spring ho immediately moved said leg onto and so that it
was sustained by the leg rest..
When, however, the auxiliary shuttle box was depressed, as from the position
Fig. 9 into the position Fig. 10, the leg h³ was not free to descend because it was
supported on the rest ho and consequently the plate or binder h² was, during this
lowering of the auxiliary shuttle box put in the dotted line position Fig. 2 and
the full line position shown in Fig. 10, so that said plate or binder passed
underneath the lowermost shuttle in the magazine D, suitably supported by a bolt D¹
at the loom side.
When the auxiliary shuttle box was being moved with the lay and depressed
from the position (Figure 9) into the position Figure 2, the projection D8 from the
stand passed under the hooked end of the holder ax, said holder engaging said
projection and keeping the said stand and auxiliary shuttle box from again going
back with the lay, and after locking the stand the further movement backward of
the lay with its leg rest hº removed said leg rest from the end of the leg h³, thus
releasing said leg, so that the spring h30 on the shaft h' acted to elevate the
plate or binder h² so that it, in its closing movement from the dotted line position
Figure 2, into the full line position Figure 10, acted against one side of the lower-
most shuttle in the magazine D, and transferred said shuttle from said magazine
automatically into position in the auxiliary shuttle box.
In order that the aligning surface referred to may operate to align the side of the
shuttle held in the auxiliary box, so that said shuttle may be correctly thrown there-
from, the said auxiliary shuttle box is provided at its rear side with a series of
notches w, w, cut into the top and bottom of the said auxiliary box for a distance
beyond the lips w³ and w² thereof, so that said lips may enter freely the spaces
between the aligning surfaces w, w, and w¹, w¹, and the said notches may embrace
freely said aligning surfaces.
The inner side of the plate or binder 2 will preferably be provided with some
suitable non-metallic material, such for instance as leather or rubber, as represented
at 10
.
When the filling fails in the running shuttle box its absence is detected in the
shed while the lay is moving forward and while the shuttle containing the failed
filling is in the box at the opposite end of the lay, and at the next backward stroke
of the lay the shuttle having the failed filling is thrown back again into the running
shuttle box, this being done preparatory to putting the auxiliary shuttle box with its
spare shuttle into its operative position at the level of the race of the lay.
The loom side is provided with a shuttle stop wo, it occupying a position opposite
the outermost open end of the auxiliary shuttle box, so that said shuttle cannot by
any accident get out of proper position in the said shuttle box so that its ends will
strike any part of the lay as the spare shuttle is being put into position to be thrown
onto the lay.
