I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester,
both in the County of Lancaster, 118, New Street, Birmingham, in the County
of Warwick, and 322, High Holboru, in the County of Middlesex, Civil Engineer,
do hereby declare the nature of this invention to be as follows:-
The present application for Letters Patent relates to a machine for the auto-
matic insertion of bobbins in the shuttles of embroidering machines.
The device consists essentially of a shuttle feeder and of a bobbin feeder in
combination with arrangements for placing one bobbin in each separate shuttle,
further in a clip device for the temporary seizing and holding thereof as well
for bringing the end of the thread under the spring thread clip on the cover of
the shuttle, and of a draw-hook for the thread in order to draw the end of the
thread through the wall of the shuttle.
In the accompanying drawings the machine is illustrated in one constructional

In the following paragraphs for the sake of greater clearness the constructional
arrangements of the most important organs and mechanisms coming into con-
sideration for the purpose of the operation will be described without special
reference to the combined operation, which latter will be subsequently set forth
separately.

page_text: At the left side of the machine is placed the sloping channel A serving to
receive the shuttles and to deliver the same singly to the machine. In this
channel the shuttles lie close to one another with the cover uppermost (Figures 2
and 3). At its lower end the channel A has a leaf spring a, which projecting
downwards through a slot in the cover of the channel, secures the foremost
shuttle which lies close to the mouth of the channel from unintentional falling
out thereof and consequently also retains the other shuttles. In the bottom of
the channel close to the mouth thereof are provided two holes close to one
Beneath the end of
another and perpendicular to the side of the said channel.
the channel and below these holes is placed the device A which can operate the
ejection of the shuttle nearest to the discharge end and consequently the de-
livery of the said shuttle into the machine or the shuttle-support. This device
comprises an ejector with angers a' placed close together and corresponding to
the position of the holes, which ejector can move up and down in such a
manner, that the fingers can enter the channel behind the shuttle lying nearest
to the orifice of the channel. This mechanism is moreover so arranged, that
the said fingers in their upwards motion in the channel, passing over the side
wall of the shuttle upwards, press the said shuttle towards the orifice, so that
the resistance of the spring a² is overcome, and the shuttle can fall out of the
channel. The fingers a are guided in a plate fixed to the frame and are sup-
ported upon another plate at, which latter is held by means of a lever a³, which
lever is revoluble upon a shaft af and possesses a projection a' which projects
below. Another projection 8 attached to a slide B₁ can act upon the projec-
tion a, the said slide B carrying the piece B which receives the shuttle. This
projection, when the piece B is moved towards the orifice of the channel A¹ to
receive the shuttle, strikes upon the projection and thereby causes the motion
of the lever a, by means of which the fingers are moved upwards in the manner
already described (Figure 3). When the slide with the piece B after receiving
the shuttle again proceeds to the right, and the projection aforesaid releases the
projection a and the projection 8 releases the projection a the plate at sinks
down with the fingers a' under the influence of its own weight or of another
projection a suitably attached to the slide B and acting at the proper time upon
the projection a', so that the fingers are caused to quit the channel and move
back into the position of rest shewn in Figure 11. At the right hand end of the
track of the slide B¹ carrying the shuttle carrier B there is supported in bearings
at the side a drum or disc M revoluble upon the axle a fixed in a frame; this
drum contains the bobbins. The drum M possesses in or about its periphery m¹
a series of holes m² arranged close together at regular intervals horizontal and
parallel to the axis; these holes are destined to contain the bobbins. (Figures 1,
2, 17, 18 and 32). To the aforesaid drum there is fixed at one side the gear-
wheel m³, the number of whose teeth is equal to the number of the holes in the
rim m', and in which there engages the lever m', which latter is articulated to
another lever m influenced by the eccentric and having its lower end sup-
ported upon an axle 2. (Figures 1 and 2). This lever m³ is arranged to receive
at the proper time such a motion from the eccentric e' placed upon the shaft w'
that the lever m is advanced and the gear-wheel is revoluble by the distance
of one tooth and consequently the drum M by the distance of one hole. The
inädvertent turning backwards of the drum M can be prevented by a ratchet
catch m attached to the drum and controlled by the leaf spring m. This
spring m can also retain the lever m in contact with the gear wheel whilst in
its advanced position. There is further provided on the frame a roller m8 which
serves to guide the lever m into its drawn-back position and prevents it from
falling down. In connection with the drum there is provided an ejector N
which is placed at the same height and in the same direction as the drum axle,
and also at the same distance from the lioles in the drum, so that when the
single forward motion has been effected the ejector can always project the respec-
tive bobbin which has thus been brought into its sphere of operation and at the

page_text: same height as the said ejector, out of the hole in the drum upon the plate
placed in front of the said drum and lying at the right side end of the track o
the shuttle-carrier. For this purpose the same is adjustably supported in
loop n and articulated to a revolving lever n, which is controlled by means of th
eccentric e² and attached at its lower end to a shaft wt. (Figures 1 and 2). The afore
said eccentric e² against which the revolving lever n presses by means of a roller n
is fixed upon a shaft perpendicular to the shaft and driven from this
latter by means of the cone wheels 22. From the eye of the lever there pro
jects downwards a bar upon which engages the spiral spring ³ attached to the
which spring has the tendency to hold the roller 2 pressed against the periphery
of the eccentric, which latter can give to the ejector the requisite ejecting motion
by means of which it passes through the respective hole m² and projects the
bobbin therein upon the plate (Figure 17). The carrier B receiving the shuttle
is placed as already stated upon a slide B which travels in a track B2 and
which supports the said carrier B near to its right side end. The left side wal
of this carrier is constructed as a movable clip 6', so that during the operations
of the opening of the shuttle, the insertion of the bobbin and so forth, the said
carrier will hold fast the shuttle which is previously inserted loosely therein (see
Figure 3). This clip b is fixed by eyelets 63 revoluble upon the shaft or axle b
supported in eyelets 6* attached to the fixed (right hand side wall or cheek b
of the shuttle) and which at about its middle has a little eccentric or projection b
This device is intended to press the shuttle upwards during the above mentioned
operations and thereby to hold it fast in the carrier against the motion down-
wards 01° upwards (Figures 6 to 11). On the front side of the
carrier there is placed revoluble upon the shaft 66 a lever b
articulated to the movable side piece b', which lever 67 supports at its free end the
roller 68. At the front of the foremost one of the guides forming the track B
for the slide B₁ is placed a plate 69 having an upper edge rising in curved form
from right to left and lying in the track of the said roller. Upon this upper
edge when the slide with the carrier moves to the left, the aforesaid roller b
travels in such a manner that the lever 7 brings the clip 61 of the carrier in to
the open position (Figure 2) and this in opposition to the pressure of the
spring 6, which is fixed upon the slide and acting from below on the clip
strives to hold this latter in the closed position. When the carrier with the
shuttle again moves to the right, and consequently the roller 68 has quitted the
plate by the plate is then pressed fast against the side of the shuttle by means of
these springs. At the hinder part of the carrier is fixed a cam 6 upon the
shaft which serves to cause such a revolution of the shaft b that the pro-
jection arrives at its uppermost position (Figures 10 and 28). For this pur-
pose there is provided on the hindermost guide piece forming the track B² of
the slide B¹ in the course of the cam 6 a catch e, which being formed as a two
armed lever revolves upon a pin c¹ in such a manner, that according to the
manner of actuation, either the one hooked-shaped arm or the other less
curved arm 3 comes to stand in the track of the cam b. In Figure 11 this
latter is illustrated as in its middle position. The position shewn in dotted lines
is that which it assumes when the shuttle carrier after receiving the shuttle moves
away from the orifice of the channel, that is to say, from left to right. Hereupon
the piece engages with the arm c³, and this latter is turned out of the position
shewn in dotted lines into the middle position shewn in black lines; whilst at
the same time the cam & itself and the shaft 66 receive such an amount of turn-
ing that the projection or eccentric 65 arrives in its highest position (Figure 10).
When the shuttle moves backwards after it has been filled and closed, the cam b
which can pass freely below the arm then strikes against the inner surface
of the arm 2, whereby this latter and the projection is caused to move upwards
into the position shewn in dotted lines, and at the same time the cam 6 and the
shaft receive such an amount of turning that the eccentric or projection 65
is again turned downwards. In order to limit the motion of the catch
in the middle position there is provided a projection R; and in order

page_text: to prevent the said catch being too easily moved, that is in order
to give it a sufficient power of resistance to ensure that when the
cam strikes upon one arm of the catch not only is the catch moved by the
cam, but also the cam is actuated by the catch there is provided at one side the
spring which acts upon the piece fixed upon the revolving axle c¹ and pro-
vided with sloping surfaces (Figures 11 and 31). The motion of the carrier B
or of the slide B is obtained by means of a jointed lever 612, 613, the part bla
whereof strikes against a projection 6 attached to a piece 10 fixed underneath
the slide, whilst the lever b oscillates upon the shaft 2 and applies itself by
means of the roller against the periphery of an eccentric placed upon the
shaft (Figure 3), or is held thereon by the pressure of a spring 15. Sideways
in front of or over the track of the carrier and about in the middle between the
orifice of the channel and the plate there is placed a rod or raising and catching
arm H, which arm when the carrier moves away with the shuttle, that is when
the same moves to the right towards the plate o, can effect the opening of the
cover of the shuttle. This arm is adjustable and revoluble in the forked free
end of another lever and possesses at its front end a finger h, by means of
which it can. engage with the projection placed sideways to the shuttle cover d
for the purpose of effecting the opening. The arrangement of the acting parts
for the purpose of the displacement, revolution and up and down motion of the
arm H is such, that this arm is in its highest position at the commencement of
the motion of the carrier and that it subsequently sinks and is drawn back and
turned so that its finger is directed diagonally from left to right and projects into
the aperture d (Figure 15); the arm is then caused to revolve from right to
left, so that the finger is caused to lie almost horizontal against the under side of
the lid (Figure 16), after which the arm is caused to rise and is pushed forward
at the same time, thus causing it to turn the cover of the shuttle upwards and
backwards consequently to open it, until the said cover takes a position almost
at right angles to the shuttle: the said arm then remains in the raised and
advanced position until the next movement, as indicated in Figure 12 in dotted
lines. The up and down motion of the arm is effected by the corresponding
oscillation of the lever which is placed upon a shaft, controlled by the
lever directed downwards. This lever has at its lower unattached end a
roller which presses against the periphery of an eccentric placed upon the
sau shaft close to the eccentric e, or the said lever may be held fast against
the periphery of the eccentric by means of a spring h, which is constructed to
correspond to the operation contemplated. The displacement of the arm H is
effected by means of a double armed lever hh, which is hinged upon a projec-
tion of the lever h¹, and which possesses a fork at the other end of its arm h³,
which fork engages between projection upon the arm H close to its hinder
end. On the other hand the free end of the arm provided with a roller, rests
upon a curved guide h8 fixed upon the machine frame. The curve of this is of
such a shape that when the lever is caused to turn the levers hand he move
in accordance with the object in view, and thereby the requisite displacement
of the arm H forwards or backwards can be effected according to requirement.
The turning of the arm and of the piece out of the position shewn in Figure 15
into the position shewn in Figure 16, is effected by imparting to the shuttle a
little backward motion (to the left) by means of its actuating mechanism, so
that the side wall of the shuttle pressing thereby upon the projection itself causes
the requisite turning of the said projection. This turning is assisted by means
of the spring which is fixed to the under side of the lever h¹ and the front end
of which acts upon the projection 10 of a connecting link h" upon the arm H
between the fork of the lever h¹. The said link has in opposition to the pro-
jection 10 a pin upon which there is fixed a spiral spring, which spring can
press the projection and the arm H back into their original position. To the
right side of the lever is placed a bar 3, the upper end of which is curved
towards the lever in such a manner that when the lever with the arm H
reaches its uppermost position, the end of the spring strikes the end of the

page_text: bar h, and is thereby turned downwards, as shewn in Figure 12 in dotted lines.
Thereupon the spring 2 is able to press the arm or the projection h back into
the original position and the said projection of the arm H moves upwards (thus
stretching the spring 12) and is held by means of the spring in the position
shewn in Figure 16. In this manner, when the arm H has been impelled into
the highest position the projection h again passes from the position shewn in
Figure 16 into the position shewn in Figure 15 and in dotted lines in Figure 12.
The support or assistance of the turning of the projection by means of the
spring his so arranged that when the projection is turned so far by means of
the side of the shuttle or of the link ", that the projection 10 has already passed
oyer the vertical position to the left, the spring by reason of its action upon
the projection, turns the link and consequently the arm and projection by a jerk
still further to the left into the position shewn in Figure 12. On this further
motion the carrier with the shuttle finally reaches the plate o placed at the end
of the track B2 on which plate as already stated the bobbin lies ready for in-
sertion: Behind the plate o there is arranged upon the slide a clip device K
and the inserting mechanism E E of which the first has the object to take hold
of the end of the thread of the bobbin when it is delivered from the drum M and
to hold it fast until the same has been seized by the thread holder hereinafter
described, which draws the thread under the thread spring clip fixed upon the
cover of the shuttle. The inserting mechanism on the other hand is devised to
eject the bobbin from the plate o in such a manner that it falls into the shuttle,
consequently to insert the bobbin in the shuttle, and at the same time to ensure
its correct position therein. The clip device possesses two claws which can
be opened and closed, and which are suspended upon a boat oscillating upon
a piece k placed revolubly upon the slide 0. These claws are formed of two
double levers crossing one another at their point of suspension, which are open
at the moment during which the bobbin is thrust out by means of the ejector N
upon the plate O, so that the projecting end of the thread comes directly between
the open jaws thereof and this immediately closes upon it. The opening of the
jaws is effected by means of the projection fixed upon the frame or upon the
front bars forming the track B2, said piece having the shape towards the said
jaws of an equilateral triangle, and which is placed in the track of the hinder
arms of the clips or jaws and at the height of their pivot . These hinder jaws
have projections of special shape * turning inwards, which correspond with the
special shape of the piece. On the backward motion of the slide after inser-
tion immediately before the bobbin has been pushed upon the plate o, the said
parts of the jaws strike the corresponding parts of the projection whereby
the jaws are caused to open. This opening is so arranged that it takes place
immediately at the moment in which the bobbins are pushed forward. In the
next instant the jaws close again because in consequence of a further motion of
the slide O the piece passes behind the projections of the jaw possessing the
parts marked so that the spring acts thereon to close them again. The
projection, can be revolved so that when the slide goes forward it can be
turned sideways out of the way by means of the projection of the jaw already
described; moreover a spring placed upon the pivot of the said projection can
return it again to its original position as soon as the displacement of the parts
have passed by. (See Figures 17 to 20). The piece k is made revoluble for the
purpose of enabling the jaws to be placed within the sphere of action of the
thread guide T which takes the end of the thread from them (see Figure 19).
The requisite turning in this position and the turning back again into the
position shewn in Figure 17 in which the jaws are shown with their outer ends
close to the plate o, is effected by means of a curve on which engages the
piece fixed upon the side arm of the piece k+. In the motion of the slide
to the left towards the plate o as is obvious from the shape, of this curve as shewn
in the drawing the claws are in the position shewn in Figure 19 so that the
thread guide T can reach the end of the thread of the bobbin placed at this motion

page_text: of the slide in the shuttle; when the slide moves away to the right the jaws are
again moved back into the position shewn in Figure 17. The inserting device
has the piece E which sits loosely upon the shaft f¹ supported upon a bearing
piece placed on the slide beside the piece. E has at its front end two
face-plates which when the slide advances can push the bobbin from the
plate o down into the shuttle holder. Between these two plates there is a space
or channel in which fits the front end of a double-armed lever also placed
revolubly upon the said shaft f¹ close to the piece E. This piece is called the
presser and marked E' and it has the duty of holding the bobbin in the right
position whilst it is being inserted, that is to say in such a position that its
longitudinal axis is approximately parallel with the longitudinal axis of the
shuttle. The presser E has for this purpose at its front end a plate e which lies
upon the bobbin, when it is in action, that is to say, when on the advance of the
slide it commences to sink down from the uppermost position. The hinder
arm of the presser which stands under the influence of a spring attached to the
shaft f', is in contact with the roller ffixed to a bearing f, which in turn is
secured to the hindermost projection forming the guide of the track B2 for the
slide B and the slide 0.
On the backward motion of the slide (to the right) the arm fo slides down along
the roller whereby the presser is turned so that its front arm bearing the
plate e is raised. After the motion to the left of the slide on the other hand, the
front arm of the presser sinks under the influence of the spring, so that the
plate e rests upon the bobbin, and holds it fast whilst the plates or the pusher
force the same towards the shuttle. The plate e is somewhat sloped off on its
hinder edge. so that it cannot remain hanging behind the edge of the shuttle
when the slide moves backwards, but can slide up upon the same on the plate o.
The motion of the slide is effected by means of a rod o³, which engages against
a projection of underneath the slide and which is articulated to a lever o³
attached revolubly upon the shaft 2. The lever o bears by means of a roller o
upon the periphery of an eccentric placed upon the shaft and is held pressed
down on the same by means of a spring e10. (Figs. 2 & 18). Simultaneously
with the insertion of the bobbin the thread guide T comes into action, which as
already stated has for its object to take the thread out of the jaws and to draw
the same through underneath the spring clip placed upon the cam of the shuttle.
This thread guide T is arranged to oscillate horizontally on the hinder side of the
track B in such a manner that when it swings forwards (in the direction of the
arrow in Figure 19) which can seize the thread held by the jaws having the
clips and then swinging back again can take the said thread with it and
draw it under the clip spring. For this purpose the thread guide is placed upon
the upper end of a vertical shaft which is placed so as to be revoluble and
at the same time movable vertically in a cylindrical housing s (Figure 1). For
the purpose of the vertical adjustment the shaft has over this housing a muff s
and the lower edge of which is provided with the cams which are in connection
with similar cams on the upper edge of the housing. These cams 23 are
of such a shape that when the shaft turns as the thread guide swings forward,
the cams of the muff 2 slide upwards over the cams of the housing and thus
the shaft with the thread guide is caused to rise, whilst on the turning of the
shaft during the back stroke of the thread guide the cams of the muff again slide
downwards whereby the shaft with the thread guide is caused to sink and
finally to arrive at its lowest position (Figure 1). The turning of the shaft is
effected by means of a lever f³ resting horizontally upon it (Figures 1 and 19)..
On the free end whereof a lever bar engages, which is articulated upon the
previously mentioned lever m³ (Figure 2) close beside the bar m². The afore-
said lever m which is actuated by the eccentric e¹ is revoluble upon the shaft 2
and bears at about its centre a roller m³ which presses against the periphery of
the said eccentric being held against the same by means of the spring m10 attached
to the lower part of the lever Figure 2. The thread guide T consists of two parts;

page_text: a lower part attached directly to the shaft 06, having the clip and marked t
and another upper part 3 fixed upon the first one having the clip t. The part
as specially shewn in side view (Figure 21) is mounted revolubly as a double-
armed lever upon a bearing on the lower part and the spring 15 acting' upon the
hinder arm presses the front arm of this part upon the part t'; consequently
the clips are held close together. The opening of the clips at the proper
time is effected by means of an arm to placed revolubly upon the lower part t',
which arm has at its upper end a projection 7 engaging over the end of the
hinder lever arm of 3. In this hinder lever arm of the part are arranged
close together two cavities with which the aforesaid projection 7 of the lever to
can be brought alternately into action. The arrangement is consequently so
planned that when the projection as shewn in Figure 19 and 21, engages in the
hinder cavity, the front lever arm of rests close on and consequently the
clips are closed (Figure 25) whilst if the projection
18 in the
front cavity, the part 3 with its hinder lever arm is pressed 50
far away that the upper lever arm stands off from the part and consequently
the clips are opened. The adjustment of the arm by means of which the
projection is brought into action" at one time with the one and at another time
with the other cavity is effected by the pieces (8 which are so placed in the
track of the thread guide, that the lever 6 with its projection strikes on them
and is thereby adjusted. The projections are placed upon a lever (10, which is
fixed upon a bar attached to the hinder guide rail of the track 32; the pro-
jection attached in front to the arm has the effect of causing the projection t
to engage in the hindermost of the cavities (Fig. 21), whilst the piece to placed at
the side of the arm causes the projection to engage in the front cavity respectively.
The action of the device is as follows;
18
When the thread-guide has swung into its hindermost position (Figure 27)
the projection strikes upon that of 18 and thereby opens the clips, which remain
opened during the advance of the guide until this apparatus reaches its further-
most front position (Figure 26). When in this position the clips have between
them the end of the thread which is being held by the jaws beforementioned.
At this moment the projection strikes the projection and thereby effects
the closing of the clips tt, so that the said thread is held fast between the said
clips. When the device moves back again the thread is drawn out from between
the jaws, which are simultaneously opened for this purpose by means of a pro-
jection placed in front upon the clip, and which piece t possesses a knife-
edged piece to which is of similar profile to the finger and acts in like manner.
The jaws have at their front ends the one the projection * and the other 12* so
placed that when the thread guide swings into its foremost position (Figures 19
and 26) or retreats again out of this foremost position, whereby the piece to passes
through between the projections, and thereby momentarily opens the
jaws, so that the clips 12 of the thread guide draw out the thread from the
jaws and take it with them. The thread-guide then moves back and draws
the thread into the groove 2 in the hole and under the thread clip 64 and
around a projection 16 upon the side of the carrier by means of which the
thread is put in tension. (Figure 27). Near the ejector N and the plate
opposite to the arm H effecting the opening of the cover, there is placed a lever P
effecting the closing of the cover, which acts almost at the same time as the
thread guide immediately after the insertion of the bobbin. This lever P which
bears at its front end a pressure roller pis supported at its hinder part p¹ in a
fork as shewn in Figures 19 and 21. The said fork is bent in a curve so that
the lever on its forward motion is so moved that its front part which acts by
means of the roller upon the cover of the shuttle sinks down consecutively
and thereby presses down and closes the cover. The lever P receives its motion
from another lever 72 which is supported upon the shaft and stands under
the control of an eccentric e (Figure 2) against which there presses a roller p³
placed on the lever 2, which roller is held pressed against the periphery of the
o and

page_text: is
eccentric by means of a spring p' which is attached to a pin placed on the bear-
ing of the lever. The motion of the pressure lever so arranged
that this latter comes in contact with the cover immediately after the
insertion of the bobbin and shuts its (Figure 19) and then immediately
returns to its original position (Fig. 1). The return of the pressure lever takes
place almost simultaneously with the return of the thread guide T, and the
advance thereof is also almost simultaneous with the advance of the said guide T.
Below the track B2 and between the guide pieces forming the same is suspended
an oscillating elbow lever 9 which at its upper end carries the thread drawing
hook G. The shuttle support or rather the movable check 6' thereof has a
slot go (Figure 10) through which the upper part of the lever g can pass with the
drawing-out hook. After the cover of the shuttle is closed and the thread has
been brought by means of the thread guide into the position shewn in Figure 27,
the slide 13 passes so far to the left that the lever 9 moving upwards can pass
with its hook G through the opening g° and through the corresponding slot d³
in the side of the shuttle and another aperture de in the
of the shuttle and past the thread into its uppermost position shewn
in Figure 28, it then returns immediately and consequently carries
the end of the thread with it, because it draws the
clips which open at this moment (in consequence of the striking of t upon 18),
and draws the same to the outside through and , all as shewn in Figure 29.
The lever revolving upon the pivot g² receives its motion from another left
lever which engages on a projection g of the lever g and which is articulated
to another lever g, placed revolubly upon the shaft w² and controlled by an
eccentric e fixed upon the shaft w against the periphery of which eccentric a
roller upon the lever g is pressed by means of the spring g connected to the
said lever (Figure 1).

the
On the further motion of the slide after the end of the thread has been brought
in the manner above described by means of the thread drawing-out hook into
the position requisite for use, the shuttle whose cover is only lightly closed
comes under the action of the pressure device (Figures 13, 14 and 30). This
projection is placed upon the base on the front end of the lever ', and is held
in the position of action (that is projecting downwards) by means of a torsion
spring attached to the said base. The eccentric et which controls the motion
of the lever is so constructed that as soon as the slide B¹ and the support B with
the filled shuttle pass beneath the projection 1, the lever receives a short de-
pression by means of which the projection is pressed firmly upon the shuttle
cover, so that the same is caused to close into the notch made for this purpose in
the shuttle wall (Figure 30).
The projection aforesaid is revoluble under spring pressure, so that it can be
turned to one side during the sudden to-and-fro motion of the slide at the open-
ing of the cover by means of the cheek piece of the support B as already
described. After the cover has been firmly closed and consequently the shuttle
has been brought into full working condition, the same is moved by the further
motion of the slide to the left, that is to the orifice of the channel within the
sphere of action of the ejector R (Figures 1, 2 and 31), which is placed between
the thread guide and the channel orifice so that it can pass into the support of
the shuttle after the cheek piece b¹ of the support and the eccentric or the pro-
jection have come into the released position, and can eject the shuttle, which
then falls into the discharge channel R. This motion of the ejector is effected
by means of the lever jointed to the ejector, said lever oscillating upon the
shaft and standing under the influence of the eccentric ed against the periphery
of which a roller r¹ attached to the said lever r is pressed by means of a spring
as shewn in Figures 1 and 2.
All the parts which are of importance in the working of the mechanism have
now been described; it is, however, still necessary to mention some parts which
may be applied for the sake of convenience. Amongst these is a spring a¹ which

page_text: is attached to the front side of the bearing a carrying the revolving axle a
and placed upon the other guide piece, for the purpose of closing the shuttle
support in front on the insertion of the shuttle, and so of preventing the falling
down of the same (Figure 2); further the arm i placed upon the bar 13 for the
same purpose, which bar possesses the projection placed at the left side of the
plate o in such a manner that its stands before the front opening of the shuttle
support at the time when this latter arrives at the plate o for the purpose of
receiving the bobbin. By this means any pushing out of the shuttle from the
support when the cover is being closed is prevented (see Figures 2 and 12).
Further there is provided on the front part of the plate f a projection f* bent
sideways to the front and behind the clip a projection (Figures 17 and 19).
Both of these projections are designed to secure the exact guiding of the thread
in the channel d, when the thread guide takes hold thereof, the former projec-
tion preventing any escape of the thread backwards that is to say towards d³,
whilst the latter prevents any slipping forward of the thread in the clips t¹³
which clips should also hold the thread with their tips.
The combined operation of the various parts is as follows.
From the supply channel A which contains the shuttles, that shuttle which
lies nearest to the mouth of the channel is delivered, thrown out by means of
the apparatus A, the fingers a¹ of which move upwards, and insert themselves
between the foremost shuttle, and the one lying immediately behind it in the
channel, whereby the foremost shuttle is pushed out of the channel, and the
spring a tending to hold the same in the channel is pressed back, so that
the shuttle falls out of the channel into the support which is standing below the
mouth of the channel and the movable clamp b¹ whereof is at the moment in
its open position ready to receive the shuttle.
In Figures 3 and 4 is shewn the position of the parts after the shuttle has
fallen out of the channel upon the support, and whilst the fingers of the pusher
are still in the channel. The position of rest of the pushing device after the
conclusion of the delivery of a shuttle, and before recommencing its action in
the channel is illustrated in Figure 11. Before the shuttle has reached the
support, there has been already delivered upon the plate o (Figure 17) the bobbin
from the revolving drum M placed at the other end of the machine and contain-
ing the bobbins, by the action of the ejector N. This bobbin is intended to
be inserted in the shuttle, which is carried forward for this purpose from its
position beneath the orifice of the channel (Figure 3), by means of the travelling
support to the plate o in the manner hereinbefore described.
In Figure 17 the position of the respective parts on the ejection of the bobbin
is illustrated; the respective position of the shuttle channel A and of the revolv-
ing drum is shewn in the elevations, Figures 1 and 2. On the ejection the
thread end of the bobbin which is placed foremost comes between the jaws ki k
(which are open at this moment) of the clip placed at the side of the plate o.
The said jaws immediately close again after having received the end of the
thread between them, and thereby hold it fast as shewn clearly in Figures 17
and 18. After the ejector N has accomplished its action as above described, it
retreats again into its original position as shewn in Figure 19. The shuttle
support is then removed from its position beneath the orifice of the channe!
(Figure 3) to the right towards the plate o upon which the bobbin is now lying.
During this passage the opening of the shuttle cover takes place. This is
effected by means of the arm H, which is placed at one side about in the middle
of the track between the mouth of the channel and the plate o.
The said arm H
is adjustable in the horizontal direction at right angles to the track of the shuttle
support, and is revoluble around its longitudinal axis, and at the same time
capable of being moved up and down, and is held by the oscillating arm h¹.
The lever H engages by means of the projection h placed at its front end in
the side cavity of the shuttle cover d in the direction from above downwards,
and then revolves upon its axis until the projection enters beneath the cover and

page_text: against the under side thereof, and finally it moves with the cover in this
position upwards and forwards at the same time, so that the cover is opened,
and placed more or less perpendicular to the body of the shuttle.
The respective working positions are illustrated in Figures 12 to 16; the
position of the lever H before it engages with the cover of the shuttle is visible
in the plan view, Figure 13.
Figures 14 and 15 illustrate the position in which the projection of the arm after
the same has revolved on its axis has entered in the cavity, and is in the act of
passing beneath the cover.
In Figure 16 the arın is shewn still further turned upon its axis, so that its
projection presses against the under side of the cover, which latter is already
partly raised. The position of the arm after the same has moved forwards and
upwards and thereby fully opening the cover, is indicated in dotted lines in
Figures 12 and 14.
In order to hold the shuttle fast during the above described operation, which
shuttle was at first, immediately after its insertion in the carrier laid loosely in
the same,
the clip of the carrier is pressed firmly against the side of the shuttle
by means of the spring bo and the shuttle is then held firmly in the support,
and any side play thereof in the support is prevented.
In order also to secure the shuttle on the support against moving upwards or
downwards, the same is held pressed upwards by means of the eccentric 65 placed
upon the revoluble shaft 66 at the bottom of the support as shewn in Figure 28.
The turning of the shaft 66 and the adjustment of the eccentric 65 in the position
of pressure is effected by means of the revolving catch c¹ (Figure 11) upon which
strikes the cam 6 placed at the end of the shaft 66 outside the carrier (Figures 7
and 8). When the cover of the shuttle has been opened, the carrier moves with
the same up to the plate o. From this plate at the moment in which the shuttle
arrives thereat, the bobbin is pushed down from the plate o into the shuttle by
aid of the mechanism E, and with the assistance of the presser E¹, which latter
rests with its front plate shaped part upon the bobbin, and thereby assures its
correct insertion in the shuttle. This presser is shewn in its raised position
ready for action in Figure 18 in black lines, and in Figure 22 in dotted lines,
whilst in Figure 17 the inserting mechanism is seen from behind in its position
of rest, and in Figure 18 in its advanced position, after the insertion of the
bobbin in the shuttle. Simultaneously with the insertion of the bobbin there
arrives the pressure lever P' placed on the opposite side to that of the arm H,
and alongside the ejector N. This lever P acts upon the open cover of the
shuttle, and shuts the same down again, so that when the bobbin is in the shuttle
the cover is immediately closed upon it.
This operation, and the different positions of the lever P are visible from the
Figures 19, 20, 21, and 22, in which the pressure lever is represented in its
position after it has pressed down the shuttle cover, whereas in Figure 21 the
position of rest of the lever before the closing is shewn in dotted lines.
Simultaneously with the action of the lever effecting the closing of the shuttle
cover there advances from the side the horizontally moving holder and guide
lever T placed close to the pressure lever, and this seizes the end of the thread
by means of its clips t t which open and close as requisite, and moving back-
wards draws the end of the thread out of the jaws of the other holding
device which have been opened by the lever T itself. Hereupon the end of the
thread reaches the guide slot placed close to the aperture of the shuttle
cover d and also the hole 3, and then passes under the spring clip d, and is
finally passed around the projection 616 placed behind upon the moving piece b¹
of the support B, and thus held in tension.
Figures 19 to 27 illustrate the various positions of the thread guide; in
Figures 19 to 22 this is illustrated in the position in which it seizes the end of
the thread after the opening of the jaws kk2, whilst Figure 23 shews the front
parts thereof in the act of opening the clips t¹ ta by means of the piece t.

page_text: Figures 24 and 25 shew the clips
open and closed positions.
holding the end of the thread in the
Figure 26 illustrates the same position as Figure 19, but in the position shewn
in Figure 26 the holder and guide T has drawn the end of the thread into the
slot and beneath the spring d and has wound it around the projection 616
and holds it stretched. The lever bearing the thread drawing out a hook G
then ascends from below, and inserts the hook G through an opening in the side
of the shuttle. On the return stroke the said hook carries the thread with it,
and draws it through the opening in the shuttle to the outside, and the thread
is released from the clips and the projection b
-
The different positions are illustrated in Figures 28 and 29, in the first of
which the hook is shewn at the time when it has risen up past the stretched
end of the thread into its uppermost position, whilst Figure 29 shews the hook
when it has again moved down after having drawn the end of the thread through
the side of the shuttle to the outside. At the next moment the hook releases the
end of the thread, and the operation properly speaking is thereby ended inas-
much as the shuttle is filled, and the end of the thread is brought into the
position for use. The support then moves with the shuttle again towards the
channel A, passing next into the range of the projection which effects the
complete closing of the cover. This piece presses the said cover which is
already in the closed position forcibly down, so that the same springs with its
front end into the slot or. groove provided for this purpose in the wall of the
shuttle, thus holding the cover in its closed position by its spring action.
This operation is illustrated in Figure 30 which shews the piece / pressing upon
the cover as described.
Upon the further motion of the support the shuttle then comes within the
range of the ejector R, which throws the shuttle out of the support into the dis-
charge channel fixed on the frame. The position of the ejector is shewn in
Figure 31.
After this operation has taken place the support moves on until it finally
'arrives again beneath the orifice of the feeding channel A', from which there
is then again delivered a shuttle, and the same is placed upon the support, and
the operation is repeated.

page_text: to be performed, to be particularly described and ascertained in and by the
following statement:-
The present application for Letters Patent relates to a machine for the auto-
matic insertion of bobbins in the shuttles of embroidering machines.
The device consists essentially of a shuttle feeder and of a bobbin feeder in
combination with arrangements for placing one bobbin in each separate shuttle,
further in a clip device for the temporary seizing and holding thereof as well as
for bringing the end of the thread under the spring thread clip on the cover of
the shuttle, and of a draw-hook for the thread in order to draw the end of the
thread through the wall of the shuttle.
In the drawings accompanying the Provisional Specification, the machine is

In the following paragraphs for the sake of greater clearness the constructional
arrangements of the most important organs and mechanisms coming into con-
sideration for the purpose of the operation will be described without special
reference to the combined operation, which latter will be subsequently set forth
separately.
At the left side of the machine is placed the sloping channel A¹ serving to
receive the shuttles and to deliver the same singly to the machine. In this
channel the shuttles lie close to one another with the cover uppermost (Figures 1
and 3). At its lower end the channel A' has a leaf spring a², which projecting
downwards through a slot in the cover of the channel, secures the foremost
shuttle which lies close to the mouth of the channel from unintentional falling
out thereof and consequently also retains the other shuttles. In the bottom of
the channel close to the mouth thereof are provided two holes close to one
another and perpendicular to the side of the said channel. Beneath the end of
the channel and below these holes is placed the device A which can operate the
ejection of the shuttle nearest to the discharge end and consequently the de-
livery of the said shuttle into the machine or the shuttle-support. This device
comprises an ejector with fingers a placed close together and corresponding to
the position of the holes, which ejector can move up and down in such a
manner, that the fingers can enter the channel behind the shuttle lying nearest
to the orifice of the channel. This mechanism is moreover so arranged, that
the said fingers in their upwards motion in the channel, passing over the side
wall of the shuttle upwards, press the said shuttle towards the orifice, so that

page_text: the resistance of the spring a² is overcome, and the shuttle can fall out of the
channel. The fingers a are guided in a plate a³ fixed to the frame and are sup-
ported upon another plate a', which latter is held by means of a lever a³ (Fig. 11),
which lever is revoluble upon a shaft a" and possesses a projection a' which pro-
jects below. Another projection a8 (Fig. 3) attached to a slide 131 can act upon
the projection a', the said slide B₁ carrying the piece B which receives the
shuttle. This projection a³, when the piece B is moved towards the orifice of the
channel A' to receive the shuttle, strikes upon the projection a² and thereby
causes the motion of the lever a³, by means of which the fingers are moved up-
wards in the manner already described (Figure 3). When the slide with the
piece B after receiving the shuttle again proceeds to the right, and the projec-
tion as releases the projection a the plate a sinks down with the fingers a¹
under the influence of its own weight or of another projection a suitably
attached to the slide 13 and acting at the proper time upon the projection a', so
that the fingers are caused to quit the channel and move back into the position
of rest shown in Figure 11. At the right hand end of the track of the slide B¹
carrying the shuttle carrier B there is supported in bearings at the side a drum
or disc M revoluble upon the axle m fixed in a frame; this drum contains the
bobbins. The drum M possesses in or about its periphery m¹ a series of holes m²
arranged close together at regular intervals horizontal and parallel to the a.tis;
these holes are destined to contain the bobbins. (Figures 1, 2, 17, 18 and 32).
To the aforesaid drum there is fixed at one side the ratchet-wheel m³, the number
of whose teeth is equal to the number of the holes in the rim m', and in which
there engages the lever m', which latter is pivoted to another lever m influenced
by the cam el and having its lower end supported upon an axle w². (Figures 1
and 2). This lever m³ is arranged to receive at the proper time such a motion
from the cam e placed upon the shaft that the lever m is advanced and the
ratchet-wheel is moved the distance of one tooth and consequently the drum M
is moved the distance of one hole. The inadvertent turning backwards of the
drun M can be prevented by a pawl me attached to the frame and under the
pressure of a leaf spring m (Fig. 32). This spring m can also retain the
lever m in contact with the ratchet wheel whilst in its advanced position. There
is further provided on the frame a roller m8 (Fig. 32) which serves to guide the
lever m into its draw-back position and prevents it from falling down. In con-
nection with the drum there is provided an ejector N which is placed at the same
height and in the same direction as the drum axle, and also at the same distance
from the holes in the drum, so that when the single forward motion has been
effected the ejector can always project the respective bobbin which has thus been
brought into its sphere of operation and at the same height as the said ejector,
out of the hole in the drum upon the plate o placed in front of the said drum and
lying at the right side end of the track of the shuttle-carrier. For this purpose
the same is adjustably supported in an eye n¹ and pivoted to an oscillating
lever n, which is controlled by means of the cam e2 and attached at its lower end
to a shaft (Figures 1 and 2). The aforesaid came against which the oscil-
lating lever n presses with a roller n² is fixed upon a shaft w³ perpendicular to
the shaft w¹ and driving from this latter by means of the bevel wheels 21 23.
From the eye of the lever there projects downwards a bar upon which engages the
spiral spring attached to the frame, which spring has the tendency to hold
the roller pressed against the periphery of the cam, which latter can give to
the ejector the requisite ejecting motion, by means of which it passes through
the respective hole m² and projects the bobbin therein upon the plate o (Figure 17).
The carrier B receiving the shuttle is placed as already stated upon a slide 131
which travels in a track B2 and which supports the said carrier B near to its
right end. The left side wall of this carrier is constructed as a movable clip b¹,
so that during the operations of the opening of the shuttle, the insertion of the
bobbin and so forth, the said carrier will hold fast the shuttle which is previously
inserted loosely therein (see Figure 3). This clip is fixed by eyelets 63

page_text: revoluble upon the shaft or axle b, supported in eyelets * attached to the fixed
(right hand side wall or check 2 of the shuttle carrier) and which at about its
middle has a little cam or projection. This device is intended to press the
shuttle upwards during the above mentioned operations and thereby to hold it
fast in the carrier against motion downwards or upwards (Figures 6 to 11). On
the front side of the carrier there is placed revoluble upon the shaft 66 a lever 67
pivoted to the movable side piece 1, which lever 7 supports at its free end the
roller 8. At the front of the foremost one of the guides forming the track B2
for the slide B is placed a plate having an upper edge rising in curved form
from right to left and lying in the track of the said roller. Upon this upper
edge when the slide with the carrier moves to the left, the aforesaid roller 68
travels in such a manner that the lever brings the clip of the carrier in to
the open position (Figure 3) and this in opposition to the pressure of the
spring (Fig. 6), which is fixed upon the slide and acting from below on the
clip strives to hold this latter in the closed position. When the carrier with
the shuttle again moves to the right, and consequently the roller 68 has quitted
the plate 6 the clip is then pressed fast against the side of the shuttle by means
of this spring. At the hinder part of the carrier is fixed a cam upon the
shaft 6, which serves to cause such a revolution of the shaft 66 that the projec-
tion 65 arrives at its uppermost position (Figure 10). For this purpose there is
provided on the hindermost guide piece forming the track B³ of the slide 13¹ in
the course of the cam 4 a catch c', which being formed as a two armed lever
revolves upon a pin e in such a manner, that according to the manner of actua-
tion either the one hooked-shaped arm 2 or the other less curved arm c³ comes
to stand in the track of the cam 6. In Figure 11 this latter is illustrated as in
its middle position. The position of the curved arm 3 shewn in dotted lines is
that which it assumes when the shuttle carrier after receiving the shuttle moves
away from the orifice of the channel, that is to say, from left to right. Hereupon
the piece engages with the arm c³, and this latter is turned out of the position
shewn in dotted lines into the middle position shewn in full lines; whilst at the
same time the cam itself and the shaft 66 receive such an amount of turning
that the projection or cam 65 arrives in its highest position (Figure 10). When
the shuttle moves backwards after it has been filled and closed, the cam 64 which
can pass freely below the arm c³ then strikes against the inner surface of the
arm (Fig. 11), whereby this latter and the projection is caused to move upwards
into the position shewn in dotted lines, and at the same time the cam 6 and the
shab receive such an amount of turning that the cam or projection 65 is again
turned downwards. In order to limit the motion of the catch in the middle
position there is provided a projection R; and in order to prevent the said catch
being too easily moved, that is in order to give it a sufficient power of resistance
to ensure that when the cam strikes upon one arm of the catch not only is the
catch moved by the cam, but also the cam is actuated by the catch there is pro-
vided at one side the spring c³, which acts upon the piece co fixed upon the
revolving axle e¹ and provided with sloping surfaces (Figures 11 and 31). The
motion of the carrier B or of the slide B is obtained by means of a link and
lever 213, the link whereof is pivoted to a projection 611 attached to a
piece 10 fixed underneath the slide, whilst the lever 613 oscillates upon the
shaft and applies itself by means of the roller 14 against the periphery of an
cam e placed upon the shaft w¹ (Figure 3), or is held thereon by the pressure of a
spring 15 Sideways in front of or over the track of the carrier and about in the
middle between the orifice of the channel and the plate there is placed a rod or

ally from left to right and projects into the aperture d¹ (Figure 15); the arm is
then caused to revolve from right to left, so that the finger is caused to lie almost
horizontal against the under side of the lid (Figure 16), after which the arm is
caused to rise and is pushed forward at the same time, thus causing it to turn
the cover of the shuttle upwards and backwards consequently to open it, until the
said cover takes a position almost at right angles to the shuttle; the said arm
then remains in the raised and advanced position until the next movement, as
indicated in Figure 12 in dotted lines. The up and down motion of the arm
is effected by the corresponding oscillation of the lever which is placed upon
a shaft w, controlled by the lever 2 directed downwards. This lever has at its
lower unattached end a roller h³ which presses against the periphery of an
cam e placed upon the said shaft w¹, close to the cam e³, or the said lever may be
held against the periphery of the cam by means of a spring h, which is con-
structed to correspond to the oneration contemplated. The displacement of the
arm His effected by means of a double arm lever h5 h6, which is hinged upon a
projection of the lever h', and which possesses a fork at the other end of its
arm h, which fork engages between projections upon the arm H close to its
hinder end. The free end of the arm provided with a roller, rests upon a
curved guide 8 fixed upon the machine frame. The curve of this is of such a
shape that when the lever h¹ is caused to turn, the levers h³ and ho move in
accordance with the object in view, and thereby the requisite displacement of
the arm H forwards or backwards can be effected according to requirement. The
turning of the arm and of the piece h out of the position shown in Figure 15 into
the position shown in Figure 16, is effected by imparting to the shuttle a little
backward motion (to the left) by means of its actuating mechanism, so that the
side wall of the shuttle pressing thereby upon the projection itself causes the
requisite turning of the said projection. This turning is assisted by means of
the spring which is fixed to the under side of the lever and the front end of
which acts upon the projection 10 of a collar ¹ upon the arm H between the fork
of the lever h¹. The said arm H has on the opposite side to the projection 10 a
pin upon which there is fixed a spiral spring, the other end of which is pinned
to the lever hand which spring can pull the projection h and the arm H back
into their original position. To the right side of the lever h¹ is placed a bar h¹³,
the upper end of which is curved towards the lever h¹ in such a manner
that when the lever h¹ with the arm H reaches its uppermost position, the end
of the spring he strikes the end of the bar h4, and is thereby turned downwards,
as shown in Figure 12 in dotted lines, thus allowing the spring 12 to pull the arm
or the projection h back into the original position, the spring having been
stretched by the action of the shuttle in turning the projection into the position
shown in Fig. 16, and the spring then holding it in that position. In this
manner, when the arm H has been impelled into the highest position the pro-
jection again passes from the position shown in Figure 16 into the position
shown in Figure 15 and in dotted lines in Figure 12. The assistance of the
turning of the projection by means of the spring his so arranged that when the
projection is turned so far by means of the side of the shuttle or of the link ",
that the projection ho has already passed over the vertical position to the left,
the spring by reason of its action upon the projection, turns the link and
consequently the arm and projection by a jerk still further to the left into the
position shown in Figure 12. On this further motion the carrier with the
shuttle finally reaches the plate o placed at the end of the track B2 on which
plate as already stated the bobbin lies ready for insertion. Behind the plate o
there is arranged upon the slide () a clip device K and the inserting
mechanism EE of which the first has the object to take hold of the end of the

page_text: thread of the bobbin when it is delivered from the drum M and to hold it fast
until the same has been seized by the thread holder hereinafter described, which
draws the thread under the thread spring clip fixed upon the cover of the
shuttle. The inserting mechanism on the other hand is devised to eject the
bobbin from the plate o in such a manner that it falls into the shuttle, conse-'
quently to insert the bobbin in the shuttle and at the same time to ensure its
correct position therein. The clip device possesses two jaws which can be
opened and closed, and which are suspended upon a bolt oscillating upon a
piece placed revolubly upon the slide O. These jaws are formed of two
double levers crossing one another at their point of suspension, which are open
at the moment during which the bobbin is thrust out by means of the ejector N
upon the plate o, so that the projecting end of the thread comes directly between
the open jaws thereof and this immediately closes upon it. The opening of the
jaws is effected by means of the projection 5 fixed upon the frame or upon the
front bars forming the track B2, said piece having the shape towards the said
jaws of an equilateral triangle, and which is placed in the track of the hinder
arms of the clips or jaws and at the height of their pivot 3. These hinder jaws
have projections of special shape * turning inwards, which correspond with the
special shape of the piece . On the backward motion of the slide after inser-
tion immediately before the bobbin has been pushed upon the plate o, the said
parts of the jaws strike the corresponding parts of the projection whereby the
jaws are caused to open. This opening is so arranged that it takes place
immediately at the moment in which the bobbins are pushed forward. In the
next instant the jaws close again because in consequence of a further motion of
the slide O the piece passes behind the projections of the jaw possessing the
parts marked so that the spring acts thercon to close them again. The pro-
jection ³ can be revolved so that when the slide O goes forward it can be turned
sideways out of the way by means of the projection of the jaw already described;
moreover a spring placed upon the pivot of the said projection can return it
again to its original position as soon as the displacement of the parts have
passed by. (See Figures 17 to 20). The piece is made revoluble for the
purpose of enabling the jaws to be placed within the sphere of action of the thread
guide T which takes the end of the thread from them (see Figure 19). The
requisite turning in this position and the turning back again into the position
shown in Figure 17 in which the jaws are shown with their outer ends close to
the plate o, is effected by means of a cam slot in which engages a stud k
fixed upon the side arm 4* of the piece . In the motion of the slide to the left
towards the plate o as is obvious from the shape of this slot as shown in the
drawing the claws are in the position shown in Figure 19 so that the thread
guide T can reach the end of the thread of the bobbin placed at this motion of
the slide in the shuttle; when the slide moves away to the right the jaws are
again moved back into the position shown in Figure 17. The inserting device
has the piece E which sits loosely upon the shaft f¹ supported upon a bearing
piece (Fig. 22) placed on the slide beside the piece k. E has at its front end
two face-plates f which when the slide advances can push the bobbin from the
plate o down into the shuttle holder. Between these two plates there is a space
or channel in which fits the front end of a double-armed lever also placed re-
volubly upon the said shaft f¹ close to the piece E. This piece is called the
presser and marked E and it has the duty of holding the bobbin in the right
position whilst it is being inserted, that is to say in such a position that its
longitudinal axis is approximately parallel with the longitudinal axis of the
shuttle. The presser has for this purpose at its front end a plate e which lies
upon the bobbin, when it is in action, that is to say when on the advance of the
slide it commences to sink down from the uppermost position. The hinder
arm of the presser which stands under the influence of a spring attached to
the shaft f, is in contact with the roller f2 fixed to a bearing f³, which in turn

page_text: is secured to the hindermost projection forming the guide of the track B² for the
slide B and the slide O.
17.
On the backward motion of the slide (to the right) the arm for slides down along
the roller whereby the presser is turned so that its front arm bearing the plate e
is raised. After the motion to the left of the slide on the other hand, the front
arm of the presser sinks under the influence of the spring, so that the plate e
rests upon the bobbin, and holds it fast, whilst the plates for the pusher force
the same towards the shuttle. The plate e is somewhat sloped off on its hinder
edge, so that it cannot remain hanging behind the edge of the shuttle when the
slide moves backwards, but can slide over the same on to the "plate o.
The motion of the slide O is effected by means of a rod 02 (Fig. 18),
which engages against a projection o¹ underneath the slide 0 and
which is pivoted to a lever attached revolubly upon the shaft w³.
The lever o³ bears by means of a roller o upon the periphery of
an cam e placed upon the shaft w¹ and is held pressed against the same by means
of a spring 05 (Figures 2 and 18). Simultaneously with the insertion of the
bobbin the thread guide T comes into action, which as already stated has for its
object to take the thread out of the jaws and to draw the same through underneath
the spring clip placed upon the cover of the shuttle. This thread guide T is
arranged to oscillate horizontally on the hinder side of the track 13 in such a
manner that when it swings forwards (in the direction of the arrow in Figure 19)
it can seize the thread held by the jaws having the clips and then swinging
back again can take the said thread with it and draw it under the clip spring.
For this purpose the thread guide is placed upon the upper end of a vertical
shaft w, which is placed so as to be revoluble and at the same time movable
vertically in a cylindrical housings (Figure 1). For the purpose of the vertical
adjustment the shaft has above this housing a sleeve the lower edge of which
is provided with a cam 3 which is in engagement with a similar cam s¹ on the
upper edge of the housing. These cams are of such a shape that when the
shaft turns as the thread guide swings forward, the cam of the sleeves slides
upwards over the cam of the housing and thus the shaft with the thread guide
is caused to rise, whilst on the turning of the shaft during the back stroke of the
thread guide the cams of the sleeve again slide downwards whereby the shaft
with the thread guide is caused to sink and finally to arrive at its lowest position
(Figure 1). The turning of the shaft is effected by means of a levers carried
horizontally by it (Figures and 19), on the free end whereof a link s engages,
which is pivoted to the previously mentioned lever m² (Figure 1) close beside the
bar m. The aforesaid lever m which is actuated by the cam e¹ is revoluble
upon the shaft 2 and bears at about its centre a roller m³ which presses against
the periphery of the said cam being held against the same by means of the
spring mattached to the lower part of the lever (Figure 2). The thread
guide T consists of two parts; a lower part attached directly to the shaft 10,
having the clip 2 and marked t, and another upper part fixed upon the first
one having the clip t¹. The part 3 as specially shown in side view (Figure 21)
is mounted revolubly as a double-armed lever upon a bearing on the lower
part and the spring acting upon the hinder arm presses the front arm of
this part upon the part consequently the clips tt2 are held close together.
The opening of the clips at the proper time is effected by means of an arm t
placed revolubly upon the lower part t, which arm has at its upper end a pro-
jection engaging over the end of the hinder lever arm of 3. In this hinder
lever arm of the part are arranged close together two cavities with which the
aforesaid projection of the lever to can be brought alternately into engagement.
The arrangement is consequently so planned that when the projection t as shown
in Figures 19 and 21, engages in the hinder cavity, the front lever arm of
rests close on t and consequently the clips are closed (Figure 25) whilst if the
projection is in the front cavity, the part with its hinder lever arm is pressed
so far away that the upper lever arm stands off from the part and consequently

page_text: the clips are opened. The adjustment of the arm to by means of which the
projection is brought into engagement at one time with the one and at another
time with the other cavity is effected by the pieces t8 9 which are so placed in
the track of the thread guide, that the lever t with its projection strikes on
them and is thereby adjusted. The projections are placed upon a lever 10, which
is fixed upon a bar attached to the hinder guide rail of the track B2; the
projection attached in front to the arm has the effect of causing the projec-
tion t' to engage in the hindermost of the cavities (Figure 21), whilst the piece t
placed at the side of the arm causes the projection to engage in the front cavity
respectively.
The action of the device is as follows:-
When the thread-guide has swung into its hindermost position (Figure 27)
the projection 7 strikes upon 8 and thereby opens the clips, which remain opened
during the advance of the guide until this apparatus reaches its furthermost front
position (Figure 26). When in this position the clips have between them the
end of the thread which is being held by the jaws beforementioned. At
this moment the projection strikes the projection and thereby effects the
closing of the clips 2, so that the said thread is held fast between the said
clips. When the device moves back again the thread is drawn out from between
the jaws, which are simultaneously opened for this purpose by means of a
projection placed in front upon the clip , and which piece t possesses a knife-
edged piece to (Fig. 19) which is of similar profile to the projection 5 (Fig. 18)
and acts in like manner. The jaws have at their front ends the one the projec-
tion * and the other 2 (Fig. 23) so placed that when the thread guide swings
into its foremost position (Figures 19 and 26) or retreats again out of this fore-
most position, the piece to passes through between the projections 2, and
thereby momentarily opens the jaws, so that the clips of the thread guide
draw out the thread from the jaws and take it with them. The thread
guide T then moves back and draws the thread into the groove d² in the note d³
and under the thread clip d and around a projection upon the side b¹ of the
carrier by means of which the thread is put in tension, (Figure 27). Near the
ejector N and the plate o and opposite to the arm H for effecting the opening
of the cover, there is placed a lever P effecting the closing of the
cover, which acts almost at the same time as the thread guide immediately
after the insertion of the bobbin. This lever P which bears at its front end a
pressure roller p is supported at its hinder part in a lever as shown in
Figures 19 and 21. The said lever p is bent in a curve so that on its forward
motion it is so moved that its front part which acts by means of the roller
upon the cover of the shuttle sinks down consecutively and thereby presses down
and closes the cover. The lever P receives its motion from another lever pa
which is supported upon the shatt ut and stands under the control of a cam e6
(Figure 2) against which there presses a roller p³ placed on the lever ², which
roller is held pressed against the periphery of the cam by means of a spring 2
which is attached to a pin placed on the bearing of the lever. The motion of the
pressure lever is so arranged that this latter comes in contact with the cover
immediately after the insertion of the bobbin and shuts it (Figure 19) and then
immediately returns to its original position (Figure 21 in dotted lines). The
return of the pressure lever takes place almost simultaneously with the return of
the thread guide T, and the advance thereof is also alinost simultaneous with the
advance of the said guide T. Below the track 132 and between the guide pieces
forming the same is suspended an oscillating elbow lever which at its upper
end carries the thread drawing hook G. The shuttle support or rather the
movable side b¹ thereof has a slot 9° (Figures 1 & 28) through which the upper
part of the lever g can pass with the drawing-out hook. After the cover of the
shuttle is closed and the thread has been brought by means of the thread guide
into the position shown in Figure 27, the slide 131 passes so far to the left that
the lever moving upwards can pass with its hook G through the opening 9° and

page_text: through the corresponding slot d³ in the side of the shuttle and another aperture <
in the cover of the shuttle and past the thread into its uppermost position shown
in Figure 28, it then returns immediately and consequently carries the end of
the thread with it, because it draws the same out of the clips t t which open
at this moment (in consequence of the striking of 7 upon 18), and draws the same
to the outside through do and d³, all as shown in Figure 29. The lever a revolv-
ing upon the pivot g² receives its motion from a link g which engages on a
projection g of the lever g and which is pivoted to another lever g, placed
revolubly upon the shaft and controlled by an cam e fixed upon the shaft w¹,
against the periphery of which cam a roller g³ upon the lever g is pressed by
means of the spring 96 connected to the said lever (Figure 1).
On the further motion of the slide after the end of the thread has been brought
in the manner above described by means of the thread drawing-out hook into the
position requisite for use, the shuttle whose cover is only lightly closed comes
under the action of the pressure device (Figures 13, 14 and 30). This projec-
tion is placed upon the boss on the front end of the lever h¹, and is held in
the position of action (that is projecting downwards) by means of a torsion
spring attached to the said boss. The cam e which controls the motion of
the lever is so constructed that as soon as the slide B and the support B with
the filled shuttle pass beneath the projection, the lever receives a short de-
pression by means of which the projection is pressed firmly upon the shuttle
cover, so that the same is caused to close into the notch made for this purpose
in the shuttle wall (Figure 30).
The projection aforesaid is revoluble under spring pressure, so that it can be
turned to one side during the sudden to-and-fro motion of the slide at the open-
ing of the cover by means of the cheek piece 61 of the support B as already
described. After the cover has been firmly closed and consequently the shuttle
has been brought into full working condition, the same is moved by the further
motion of the slide to the left, that is to the orifice of the channel within the
sphere of action of the ejector R (Figures 1, 2 and 31), which is placed between
the thread guide and the channel orifice so that it can pass into the support of
the shuttle after the cheek piece 61 of the support and the cam or projection 65
have come into the released position, and can eject the shuttle, which then falls
into the discharge channel R (Fig. 2). This motion of the ejector
is effected by means of the lever jointed to the ejector R, said lever
oscillating upon the shaft w and standing under the influence of the cam
against the periphery of which a roller attached to the said lever r is pressed
by means of a spring 2 as shown in Figures 1 and 2.
All the parts which are of importance in the working of the mechanism hav
now been described; it is, however, still necessary to mention some parts which
may be applied for the sake of convenience. Amongst these is a spring a which
is attached to the front side of the bearing a carrying the revolving axle a
and placed upon the other guide piece, for the purpose of closing the shuttle
support in front on the insertion of the shuttle, and so of preventing the falling
down of the same (Figure 2); further the collar i placed upon the bar 3 for the
same purpose, which collar has a projection placed at the left side of the
plate o in such a manner that it stands before the front opening of the shuttle
support at the time when this latter arrives at the plate for the purpose of
receiving the bobbin. By this means any pushing out of the shuttle from the
support when the cover is being closed is prevented (see Figures 2 and 12).
Further there is provided on the front part of the plate f a projection f bent
sideways to the front, and behind the clip a projection (Figures 17 and 19).
Both of these projections are designed to secure the exact guiding of the thread
in the channel d² (Fig. 27), when the thread guide takes hold thereof, the former
projection preventing any escape of the thread backwards that is to say to-
wards d', whilst the latter prevents any slipping forward of the thread in the
clips which clips should also hold the thread with their tips.
t

page_text: The combined operation of the various parts is as follows:-
From the supply channel A' which contains the shuttles, that shuttle which
lies nearest to the mouth of the channel is delivered, thrown out by means of
the apparatus A, the fingers a of which move upwards, and insert themselves
between the foremost shuttle, and the one lying immediately behind it in the
channel, whereby the foremost shuttle is pushed out of the channel, and the
spring tending to hold the same in the channel is pressed back, so that the
shuttle falls out of the channel into the support which is standing below the
mouth of the channel and the movable clamp 6 whereof is at the moment in
its open position ready to receive the shuttle."
In Figures 3 and 4 is shown the position of the parts after the shuttle has
fallen out of the channel upon the support, and whilst the fingers of the pusher
are still in the channel. The position of rest of the pushing device after the
conclusion of the delivery of a shuttle, and before recommencing its action in
the channel is illustrated in Figure 11. Before the shuttle has reached the
support, there has been already delivered upon the plate o (Figure 17) the bobbin
from the revolving drum M placed at the other end of the machine and contain-
ing the bobbins, by the action of the ejector N. This bobbin is intended to
be inserted in the shuttle, which is carried forward for this purpose from its
position beneath the orifice of the channel (Figure 3), by means of the travelling
support to the plate o in the manner hereinbefore described.
In Figure 17 the position of the respective parts on the ejection of the bobbin
is illustrated; the respective position of the shuttle channel A and of the revolv-
ing drum M is shown in the elevations, Figures 1 and 2. On the ejection the
thread end of the bobbin which is placed foremost comes-between the jaws k¹²
(which are open at this moment) of the clip placed at the side of the plate o.
The said jaws immediately close again after having received the end of the
thread between them, and thereby hold it fast as shown clearly in Figures 17
and 18. After the ejector N has accomplished its action as above described, it
retreats again into its original position as shown in Figure 19. The shuttle
support is then removed from its position beneath the orifice of the channel
(Figure 3) to the right towards the plate o upon which the bobbin is now lying.
During this passage the opening of the shuttle cover takes place. This is
effected by means of the arm 1, which is placed at one side about in the middle
of the track between the mouth of the channel and the plate o. The said arm H
is adjustable in the horizontal direction at right angles to the track of the shuttle
support, and is revoluble around its longitudinal axis, and at the same time
capable of being moved up and down, and is held by the oscillating arm h¹.
The lever H engages by means of the projection placed at its front end in
the side cavity of the shuttle cover in the direction from above downwards,
and then revolves upon its axis until the projection enters beneath the cover and
against the under side thereof, and finally it moves with the cover in this
position upwards and forwards at the same time, so that the cover is opened,
and placed more or less perpendicular to the body of the shuttle.
The respective working positions are illustrated in Figures 13 to 16; the
position of the lever H before it engages with the cover of the shuttle is visible
in the plan view, Figure 13.
Figures 14 and 15 illustrate the position in which the projection of the arm
after the same has revolved on its axis has entered in the cavity, and is in the act of
passing beneath the cover.
In Figure 16 the arm is shown still further turned upon its axis, so that its
projection presses against the under side of the cover, which latter is already
partly raised. The position of the arm after the same has moved forwards and
upwards and thereby fully opening the cover, is indicated in dotted lines in
Figures 12 and 14.
In order to hold the shuttle fast during the above described operation, which
shuttle was at first, immediately after its insertion in the carrier laid loosely in

page_text: the same,
the clip of the carrier is pressed firmly against the side of the shuttle
by means of the spring 60 and the shuttle is then held firmly in the support,
and any side play thereof in the support is prevented.
In order also to secure the shuttle on the support against moving upwards or
downwards, the same is held pressed upwards by means of the cam 6 placed upon
the revoluble shaft 66 at the bottom of the support as shown in Figure 28. The
turning of the shaft 66 and the adjustment of the cam in the position of pres-
sure is effected by means of the revolving catch c (Figure 11) upon which strikes
the cam 6 placed at the end of the shaft 66 outside the carrier (Figures 7 and 8).
When the cover of the shuttle has been opened, the carrier moves with the same
up to the plate o. From this plate at the moment in which the shuttle arrives
thereat, the bobbin is pushed down from the plate o into the shuttle by aid of
the mechanism E, and with the assistance of the presser E, which latter rests
with its front plate shaped part e upon the hobbin, and thereby secures its
correct insertion in the shuttle. This presser is shown in its raised position
ready for action in Figure 18 in full lines, and in Figure 22 in
dotted lines, whilst in Figure 17 the inserting mechanism is seen
from above in its position of rest, and in Figure 18 in its
advanced position after the insertion of the bobbin in the shuttle. Simultaneously
with the insertion of the bobbin there arrives the pressure lever P placed on the
opposite side to that of the arm H, and alongside the ejector N. This lever P
acts upon the open cover of the shuttle, and shuts the same down again, so that
when the bobbin is in the shuttle the cover is immediately closed upon it. This
operation, and the different positions of the lever P are visible from the
Figures 19, 20, 21, and 22, in which the pressure lever is represented in its
position after it has pressed down the shuttle cover, whereas in Figure 21 the
position of rest of the lever before the closing is shown in dotted lines.
Simultaneously with the action of the lever effecting the closing of the shuttle
cover there advances from the side the horizontally moving holder and guide
lever T placed close to the pressure lever, and this seizes the end of the thread
by means of its clips t t which open and close as requisite, and moving back-
wards draws the end of the thread out of the jaws of the other holding
device which have been opened by the lever T itself. Hereupon the end of the
thread reaches the guide slot placed close to the aperture d' of the shuttle
cover d and also the hole ³, and then passes under the spring clip 4, and is
finally passed around the projection 616 placed behind upon the moving piece 61
of the support B, and thus held in tension.
Figures 19 to 27 illustrate the various positions of the thread guide; in
Figures 19 to 22 this is illustrated in the position in which it seizes the end of
the thread after the opening of the jaws 2, whilst Figure 23 shows the front
parts thereof in the act of opening the clips t 2 by means of the piece t.
Figures 24 and 25 shows the clips t¹² holding the end of the thread in the
open and closed positions.
Figure 26 illustrates the same position as Figure 19, but in the position shown
in Figure 27 the holder and guide T has drawn the end of the thread into the
slot d and beneath the spring and has wound it around the projection of
and holds it stretched. The lever g bearing the thread drawing out hook G
then ascends from below, and inserts the hook G through an opening in the side
of the shuttle. On the return stroke the said hook carries the thread with it,
and draws it through the opening in the shuttle to the outside, and the thread
is released from the clips and the projection 616.
The different positions are illustrated in Figures 28 and 29, in the first of
which the hook is shown at the time when it has risen up past the stretched
end of the thread into its uppermost position, whilst Figure 29 shows the hook
when it has again moved down after having drawn the end of the thread through
the side of the shuttle to the outside. At the next moment the hook releases the
end of the thread, and the operation properly speaking is thereby ended inas-

page_text: much as the shuttle is filled, and the end of the thread is brought into the
position for use. The support then moves with the shuttle again towards the
channel A, passing next into the range of the projection which effects the
complete closing of the cover. This piece presses the said cover which is
already in the closed position forcibly down, so that the same springs with its
front end into the slot or groove provided for this purpose in the wall of the
shuttle, thus holding the cover in its closed position by its spring action.
This operation is illustrated in Figure 30 which shows the piece pressing upon
the cover as described.
Upon the further motion of the support the shuttle then comes within the
range of the ejector R, which throws the shuttle out of the support into the dis-
charge channel fixed on the frame. The position of the ejector is shown in
Figure 31.
After this operation has taken place the support moves on until it finally
arrives again beneath the orifice of the feeding channel A', from which there
is then again delivered a shuttle, and the same is placed upon the support, and
the operation is repeated.
