Improvements in Connection with Shuttles of Looms for Weaving.
I, SERGIUS RIA BOUSCHINSKY, of Vishny-Volotchek, Russia, Engineer-Tech-
nologist, do hereby declare the nature of this invention to be as follows:-
This invention of improvements in connection with the shuttles of looms has
for object to provide apparatus whereby empty shuttles can be removed and
full shuttles supplied automatically without stopping the loom.
For this purpose according thereto the ordinary stop motion of the loom,
instead of stopping the loom when a weft thread breaks, is adapted to turn
a hook or its equivalent into the path of a toothed wheel fixed to a longitudinal
rod carried by the swords of the lay, the said rod extending across the loom and
being provided at one end with means for inserting a full shuttle into the shuttle
box at that end, and at the other end with means for removing an empty shuttle
from the other shuttle box, the arrangement being such that when a weft thread
breaks and the said hook is raised, the forward movement of the lay brings the
said toothed wheel against the hook whereby the longitudinal rod is partially
rotated and the moving and replacing mechanisms are actuated.
One construction of apparatus according to this invention is illustrated in the
accompanying drawings, of which Fig. I is a side elevation and Fig. 2 a plan
of an ordinary stop motion for a loomi. Fig. 3 is a front view of the lay of a
loom provided with the said apparatus and Fig. 4 a cross section thereof on the
liney, Fig. 3, together with a part of the frame. Figs. 5 and 6 are cross
sections of the lay on the line with the shuttle-removing mechanism in
normal and operative positions respectively. Fig. is a front view of the left
shuttle box with the apparatus for replacing the full shuttles. Figs. and 9
are cross sections thereof on the line, showing respectively the normal
position and the position occupied when the shuttle being dropped out of the
magazine into the shuttle box. Figs. 10 and 11 are plans of a slide plate in
normal and operative positions respectively. Figs. 3, 4, 5 and 6 are drawn
to a smaller scale than the other figures.
In looms of the ordinary type a device, comprising a hook and fork stops the
loom when the weft thread breaks.
When the
Figs. 1 and 2 show an ordinary loom stop motion of this kind.
weft thread breaks the bar c, pivoted at the point el, is moved in the direction
of the arrow Fig. 2, whereby a spring bar A (having a handle B) is released
from a notch E and the loom is stopped in the usual manner.
In apparatus according to this invention the bar c is provided with a suitable
notch opposite to the spring bar A in which the latter may enter and the
loom continue to work. As the bar c recedes in the direction of the arrow, it
moves a lever g which turns a rod w, Figs. 1 and 4, located behind the front
rollers and extending from the handle of the loom to the pinions which reel
up the woven fabric. In ordinary looms this is effected in order to switch

page_text: out, when the weft thread is broken, the pinion reeling up the fabric as the
impetus of the moving parts of the loom tends to continue its movement.
Upon the upper and lower rails, connecting the frames, is fixed a bar b (Fig. 4)
to which is secured a hook e pivoted at e and resting on the part al of the rod a.
When the weft thread is broken, the rod a raises the hook c into the dotted
line position Fig. 4, and while the lay is moving back it engages with one of
the four blades of a wheel d thus turning it one fourth of a revolution and with
it the shaft e on which it is fixed. A turning movement of one fourth of a
revolution is attained by means of a bar f pressed by a spring against a square
wheel mounted on the same shaft e (Figs. 3 and 4).
The shaft e extends entirely along the lay, underneath it, and is rotatably
mounted in brackets attached to the swords of the lay. This shaft e, while
making the said quarter of a revolution in the direction indicated by the
arrow rig. 4 effects the removal of the shuttle from one of the shuttle boxes and
drops a loaded one out of the magazine, into the other box.
For this purpose
there is mounted on one end of the shaft e a cam g (Figs. 3 7, 8 and 9), which,
while, making the quarter revolution, raises a lever k, pivoted to the lay at sl.
The lever by means of a rod m turns a shaft u (Figs. 3, 7, 8 and 9), which
moves aside a plate supporting the shuttles in the magazine m¹. At the
same time another plater passing into the magazine prevents more than one
shuttle from falling into the box at a time (Figs. 7, 8 and 9)..
The plate P
in its movement catches, by its hooked end, a jaw s which rocks on a spindle
underneath the lay. As soon as the arms of the jaws are moved away from
the lay a slide plate o comes between them and the beam thereby arresting the
mechanism in the position shown in Fig. 9) until the lay is again in the forward
position shown in Fig. 4. When this takes place the lever comes in contact
with the side frame of the loom and the slide plate o is moved from between the
arms of the jaws and the lay and a strong spring e brings the jaw and with it
the whole of the apparatus into its former position (Fig. 8). The pick then
comes on from this end and the loom continues to work with a newly loaded
shuttle. The arresting of the mechanism during one revolution of the loom,
in the position shown in Fig. 9, is done in order to give the shuttle time to fall
down into the box when the loom is running at a high speed.
While the insertion of a full shuttle is taking place at one end of the loom
at the other end the empty shuttle is being removed. For this purpose the
shafte is provided with two cams and that are adapted whilst making the
aforesaid one fourth of a revolution to raise the levers and fixed on one
shaft and moving with it about the centre d'Figs. 5 and 6. At the ends
of the levers and are attached two rods screwed to the jaw a¹ of the shuttle
box. By lifting the levers the jaw is raised and room is made for the
shuttle to be thrown out (Fig. 6). At the same time the cam = strikes a
lever, which sharply turns the spindle on which are mounted the levers d
and which knock out the shuttle through the opening thus left by the jaw
into a shoot e¹l attached to the lay (Fig. 6).
The lower end of this box is open
so that the shuttle may fall through into a suitable receptacle. A spring fl
then brings the levers into their former position, and the jaw returns to its
normal position (Fig. 5).
In order that the point of the shuttle may be prevented from remaining in the
picker while being removed from one side of the lay, thus causing the shuttle
to fall irregularly, and also that the picker may not obstruct the movement of
the loaded shuttle while dropping out of the magazine on the other side of the
lay, means are provided to draw the pickers back.
For this purpose there are hinged or pivoted to the ends of the levers and u²
two rods and g² (Figs. 3) which, by raising the said levers, release plates k¹
and from under the long arms of the cone picks, the said arms being thus
allowed to bear upon the buffers e³ and e', and the upper ends of the arms with
the pickers move away from the shuttle to the end of the groove in the lay.

page_text: After removing the shuttle at the same end of the lay a pick takes place without
the shuttle and room is made for the plate ¹ which returns to its former position
(Fig. 3). The weaver removes the empty cop from the removed shuttle and
while working drops a loaded shuttle into the open magazine m¹ to keep it
supplied, the end of the weft thread being wound on the rod n¹.
In right hand looms the removing mechanism is placed on the right hand
and the charging mechanism with the shuttle magazine on the left; in left hand
looms the arrangement is reversed.

Improvements in Connection with Shuttles of Looms for Weaving.
I, SERGIUS RIABOUSCHINSKY, of Vishuy-Volotchek, Russia, Engineer-Tech-
nologist, 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 of improvements in connection with the shuttles of looms has
for object to provide apparatus whereby empty shuttles can be removed and
full shuttles supplied automatically without stopping the loom.
For this purpose according thereto the ordinary stop motion of the loom,
instead of stopping the loom when a weft-thread breaks, is adapted to turn
a hook into the path of a toothed wheel fixed to a rod carried longitudinally to
the lay by the swords of the lay, the said rod extending across the looms and
being provided at one end with means for inserting a full shuttle into the shuttle
box at that end and at the other end with means for removing an empty shuttle
from the other shuttle box, the arrangement being such that when a weft-thread
breaks and the said hook is raised, the forward movement of the lay brings the
said toothed wheel against the hook whereby the said rod is partially rotated
and the removing and charging mechanisms are actuated.
One construction of apparatus according to this invention is illustrated in
the drawings filed with my Provisional Specification of which Fig. 1 is a side
elevation, and Fig. 2 a plan of an ordinary stop-motion for a loom; Fig. 3 is a
front view of the lay of a loom provided with the said apparatus, and Fig. 4
a cross-section thereof corresponding to the line y of Fig. 3 together with a
part of the frame; Figs. 5 and 6 are cross sections of the lay corresponding to
the line y with the shuttle-removing mechanism in normal and operative
positions respectively; Fig. 7 is a front view of the left-hand shuttle-box, with
the apparatus for inserting the full shuttles; Figs. 8 and 9 are cross sections
thereof corresponding to the line 22 and showing respectively the normal
position and the position occupied when the shuttle is being dropped out of the
magazine into the shuttle box; and Figs. 10 and 11 are plans of a slide plate
in normal and operative positions respectively. Figs. 3, 4, 5 and 6 are drawn
to a smaller scale than the other figures.
In looms of the ordinary type a device comprising a hook and a fork stops the
loom when the weft-thread breaks. Figs. 1 and 2 show an ordinary loom
stop-motion of this kind. When the weft-thread breaks the bar e, pivoted at
the point c', is moved in the direction of the arrow in Fig. 2, whereby a spring

page_text: bar A (having a handle B) is released from a shoulder E and the loom is stopped
in the usual manner.
In apparatus according to this invention the bar c is provided with a suitable
notch opposite to the spring bar A so that the bar A may enter this notch and the
loom continue to work. As the bar c moves in the direction of the arrow, it
operates a lever which turns a rod à (Figs. 1 and 4) located behind the cloth
beam and extending to the ratchet-wheel that winds up the woven fabric.
ordinary looms the effect of this is, when the weft thread is broken, to throw
out of gear the pinion that winds up the cloth, because the impetus of the moving
parts of the loom tends to continue its movement.
In
To the upper and lower rails connecting the side frames, is fixed a bar 6 (Fig. 4)
to which is secured a hook e pivoted at and resting on the part al of the rod a.
When the weft-thread is broken, the rod a raises the hook e into the dotted line
position shown in Fig. 4 and while the lay is moving back it engages with one of
the four blades of a wheel d thus turning it one fourth of a revolution and with
it the shaft c on which it is fixed. A turning movement of one fourth of a
revolution is attained by means of a lever f pressed by a spring against a square
wheel mounted on the same shaft e (Figs. 3 and 4).
The shaft e extends entirely along the lay, underneath it, and is rotatably
mounted in brackets attached to the swords of the lay. This shaft e, while
making the said fourth of a revolution in the direction indicated by the arrow
in Fig. 4, effects the removal of the shuttle from one of the shuttle-boxes and
drops a full one out of the magazine into the other shuttle box. For this purpose
there is mounted on one end of the shaft e a cam g (Figs 3, 7, 8 and 9), which
while making the quarter revolution, raises a lever k pivoted to the lay at st.
The lever K, by means of a rod m, turns a shaft (Figs. 3, 7, 8 and 9), which
moves aside a plate & supporting the shuttles in the magazine m¹. At the
same time another plate passing into the magazine prevents more than one
shuttle from falling into the shuttle box at a time. (Figs. 7, 8 and 9). The
plate in its movement catches, by its hooked end, a jaw s, which rocks on a
spindle underneath the lay. As soon as the arms of the jaws are moved away
from the lay, a slide plate o comes between them and the beam (Figs. 9, 10,
and 11), thereby arresting the mechanism in the position shown in Fig. 9 until
the lay is again in the forward position shown in Fig. 4. When this takes
place the levert comes into contact with the side frame of the loom and the slide
plate is moved from between the arms of the jaws and the lay, and a strong
spring brings the jaw, and with it the whole of the apparatus, into its former
position (Fig. 8). The shuttle is then picked from this end and the loom
continues to work with a new full shuttle. The arresting of the mechanism
during one revolution of the loom in the position shown in Fig. 9, is done in
order to give the shuttle time to fall down into the box when the loom is running
at a high speed.

of the shuttle box.

While the insertion of a full shuttle is taking place at one end of the loom,
at the other end the empty shuttle is being removed. For this purpose the
shafte is provided with two cams and that are adapted whilst making the
aforesaid one fourth of a revolution to raise the levers and ², fixed on one
shaft and moving with it about the axis c¹ (Figs. 5 and 6).
levers and are attached two rods screwed to the jaw a
By lifting the levers the jaw a¹ is raised and room is made
be thrown out (Fig. 6). At the same time the cam : strikes an arm b',
which sharply turns the spindle c² on which are mounted the arms and
which by means of a plate attached to the arms and 2, knock out the shuttle
through the opening left by the jaw into a shoot c¹ attached to the lay (Fig. 6).
The lower end of this shoot is open so that the shuttle may fall through into a
suitable receptacle. A spring f then brings the arms into their former position,
and the jaw returns to its normal position (Fig. 5).
In order that the point of the shuttle may be prevented from remaining in the

page_text: picker while being removed from one side of the lay, and being thereby caused
to fall irregularly, and also that the picker may not obstruct the movement of
the full shuttle while dropping it out of the magazine on the other side of the
lay, means are provided to draw the pickers back.
For this purpose there are hinged or pivoted to ends of the levers and u³
two rods and 2 (Fig. 3) which, when the said levers are raised, release plates 1
and (which are connected with the rods gl and g² by means of levers acted upon
by springs) from under the long arms of the picking levers which are thus
allowed to bear upon the buffers e and e, and the upper ends of the picking
levers with the pickers move away from the shuttle to the end of the slots in the
lay. After the removal of the shuttle the picking lever at the end of the lay
at which the shuttle has been removed is operated but without picking a shuttle,
and room is made for the plate ', which returns to its former position (Fig. 3).
The weaver removes the empty cop from the removed shuttle and while working
drops a full shuttle into the open magazine m³ to keep it supplied, the end of
the weft thread being wound on the pin n¹.
In right hand looms the removing mechanism is placed on the right hand
and the charging mechanism, with the shuttle magazine, on the left; in left-hand
looms the arrangement is reversed.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In a loom, the combination of the hook which is lifted by means of the
usual mechanism when the weft-thread breaks, the blade wheel d, the shaft e
connecting the removing and charging mechanisms, means for restricting the
rotation of the said shaft to a quarter of a complete revolution at each operation
thereof, the cam g with the lever k, the rod m, the shaft 7, and the plates and p
of the charging mechanism, the jaws with the slide plate o and the levert the
shuttle magazine m¹ above the shuttle box, the removing mechanism comprising
the cams and z¹, the levers 1 and 2, the rising jaw w¹, the rods connecting
the levers and with the jaw a', the arms b¹ and , and the plate carried
by the arms and 2, the plates and 2, the levers and the rods g' and g³
connecting the plates and with the charging mechanism and the removing
mechanism respectively.
2. In a loom, apparatus for automatically removing empty shuttles and supply-
ing full ones without stopping the loom, constructed, arranged, and operating
as herein before described with reference to and shown in the drawings filed with
my Provisional Specification.
