In our above-mentioned Patent No. 2,638,936 we disclose a winding machine in combination with a loom and bobbin stripping means, wherein the winder furnishes woundbobbins to the loom, the loom discharges spent bobbins to the stripper, and the stripper furnishes stripped bobbins to the winder. The present invention provides, in suchan organization, means to receive and hold the wound bobbins prior to their being placed in the loom shuttle, means to hold the end of yarn extending from wound bobbins, means to draw outor transport said end of yarnto said holding means, and means to stop the operation of thewinder when a full supply of Wound bobbins is available to the loom and to restart the winder operation when there is less than a full supply of bobbins.

GENERAL ORGANIZATION Referring to the present drawings, Fig. 1 illustrates a portion of an automatic loom at the filling-changing end, automatically-operated bobbin-winding means, including bobbin donning-and-doffing mechanism, the magazine for receiving wound bobbins, and the mechanism for receiving and holding under tension the transfer-tails from the wound bobbins. The loom may be of conventional type as regards its general organization with its automatic filling-changing mechanism modified as required for cooperation with the bobbin-winding means; and the automatic winding means maybe of a type such as shown in United States Letters Patent Nos. 2,257,651 and 2,302,- 715. The loom' may comprise the usual reciprocating lay 2; shuttle 5 received in the'box 6 at the end of the lay, the picker-stick 7 for driving the" shuttle from this end of the lo'om, and the various other instrumentalities generally employed in automatic looms.

Bobbin-winding means 7 'Patent No. 2,63 8,936 only so much of them as is necessary to a complete understanding of the present invention will be described herein. The winding mechanismis in-' Va corporated in the frame 4 of the loomand located above the filling-changing mechanism with its driving means enclosed in a housing or casing 8 and. driven by an electric motor enclosed in the casing. The Winding spindle 16 projects from one end of the casing 3 and carries a recessed driving-member or spindle-cup 11 for receiving the head h of the bobbin b as shown in 3. The tip end of the bobbin b is likewise supported in the recess of a rotatable center 12 at the end of a stub-spindle or slidable plunger 13 held in an'outboard bearing 15, similar to the tail-stock of a lathe. The outboard bearing 15 is having a serratedferrulefsurroundingits barrel adjacent tail in our above-mentioned Patent No.- 2,638,936. The

shiftable to retract the outer spindle-center 12 and release awou nd bobbin for dotting it from the winding spindle 1 0; thennstrumentalities for effecting the dofling operatron be ng ,7 described more in detail in the above-mentio'ned Patent No. 2,638,936.

V 7 Empty bobbin magazine Mounted above the winding means is a magazine '20 for containing empty bobbins b, which may be of wood or other material in conventional shape with an enlarged head h at oneflend and av barrel tapering towards its opposite t1p ;end. Preferably, bobbins b are of a type such as shown in United States Patent No. 2,614,771

bobbins aredeposited in the trough 19to cause them to slide the'realongfor positioning their he'aclsto "drop down in the chute 21 with their tip ends guided in the chute 22.. Beneath the magazine 20 are pivoted arms or levers Z3Land24carrying gripping means for graspinga bobbin from'the magazine and carrying it down into position for engagement with the driving-center 11 on the winding spindle .16 and the outer spindle-center 12 as required for donning the bob-bin to wind the yarn thereon.

Yarn-traversing means The filling-yarn y is distributed on the bobbins b by means of a yarn-guide 25 which is traversed longitudinally thereof with a relatively short stroke by means of a reciprocating traverse-bar 26. The guide is fed progressively outward along the barrel of the bobbin b by ad vancing the traverse-bar 26 through the operationot suitable means enclosed in the casing 8. In this way the layers of yarn are deposited on the wooden bobbin in conical or tapered chases which build up to form the bobbin with a cylindrical body and tapering tip-end in chines.

As the guide reaches a position adjacent the end of the bobbin b, an inclined cam-shaped projection 28 thereon, shown by fulllines in Fig. 6- and dotted lines in Fig.3, engages beneath atrip-elernent 39 fast on a control rod 31 rotatably held in bearings in the framework of the winding mechanism. This causes the control rod 31 to be rocked to release latching or detent-means for energizing the means for operating the donning and dofiing mechanism of the winding means in a manner substantially the same as described in the two patents referred to above.

B obbin-dofiing means The outboard bearing or tail-stock 15 is fastened to a spindle-center 12. when it is in engagement with the tip V l end of the bobbin b holds its head It drivingly engaged with the spindle-center II. when the bearing i5.is'mov'ed back toward casing '8. A spring 38 on the rod 34, see Figs. 3 .and 6, is compressed and loaded when the outboard bearing 15 is moved toward the casing 8 to don an empty bobbin, means being provided for latching the rod against the force of the spring to retain the bearing in operative relationship. The latching 'means is reteased at the completion of winding each bobbin to cause the spring 38 to slide the rod 34 and move the bearing 15 to the right to dofi the wound bobbin.

The operation o f the means described above moves the outboard bearing 15 to retract the spindle-center 12 and release the bobbin to dott' it from winding position and allow it to drop down into the magazine for wound bobbins in the manner as later explained.

Yarn-retriever and transfer-tail clip In starting to wind on a newly-donned bobbin the yarn is fastened thereto by sliding it under the prongs or fingers p on the ferrule f surrounding the ba'rr'el of the bobbin. The yarn trailing from the dotted bobbin is severed and its end carried outward to a tensioning drum for holding it extended from the bobbin when the latter is trans ferred to the reserve magazine of the loom. The means for performing these several functions consists in a pan of

slidable clips

83 and 84 arranged to travel first in one direction and then in the opposite direction in different parallel courses below the winding bobbin. The

clips

83 and 84 are shown in detail in Figs. and 11 and the means for sliding them in horizontal paths is illustrated in Fig. 6. A sort of rolling trolley is employed for this purpose, a reciprocable bar 85 moved by a lever in the casing 8 being connected to a carriage 87, on which are journaled two pairs of spur-gears. One pair of gears is constituted by a pinion 89 connected to a larger gear 90 arranged with the teeth of the pinion engaging the teeth on a fixed rack 91. The larger gear 90 of the pair has its teeth in mesh with a rack-bar 92 which is connected to the upper yarn-clip S3 for sliding it. The other pair of gears comprises a pinion 95 arranged with its teeth in mesh with those of a fixed racl: 91 and connected to a larger gear 97 meshing with a rack-bar 94 which is fastened to the lower clip 33 for sliding it. Through this arrangement the motion transmitted to the rod 85 is multiplied to slide the two rackbars 92 and 94 with an augmented length of traverse so as to travel the clips in opposite directions at accelerated rates of speed in the manner and for the purpose as more particularly pointed out hereinafter.

Referring to Figs. 10 and 11, the two

clips

83 and 84 are of substantially the same construction and arrangement but reversed in position with the reentrant openings between their jaws facing in opposite directions. As shown in Fig. 10, the upper clip 83, called the retriever, consists in a rectangular mounting 100 of U-shape having a fixed jaw 101 formed by one of its depending side walls which is flared outwardly at its end. A movable jaw 102 of similar shape is loosely mounted on

horizontal studs

103 and 104 projecting through the sides of the mounting 100 to adapt this jaw to rock toward the fixed jaw 101. A helical spring 105 coiled around the stud 103 acts to forcethe movable jaw 102 toward the fixed jaw 101 to clamp the yarn therebetween as it is entered between the flaring ends of the jaws. A cam-member 106 is slidably held on the under side of the mounting 100 by means of

studs

107 and 108 projecting through

slots

109 and 110 in said member. The slot 109 at the forward end of the cam-member 106 is of angular shape to cause this end of the member to be swung laterally as it is slid forward on the mounting 100. The cammember 106 has a finger 112 projecting forwardly from its slotted portion and adapted to engage with a lug 113 depending from the outer end of the movable jaw 102 to cam said jaw away from the fixed jaw 101. Nuts 114 on the ends of the

studs

107 and 108 are set up against the ends of a spring 115 which is formed with a central bowed portion bearing against the under face of the cammember 106 to hold it in place and apply a slight friction to its sliding motion. The cam-member 106 slides against a plate 116 fastened to the under side of the mounting 100, the forward end of this plate being beveled on one side to coact with the edge of the forward finger 112 of the cam-member'106 during cooperation of the flaring ends of the

jaws

101 and 102. The edges of the beveled end of the plate 116 and the finger 112 on the cam-member 106 are sharpened, as regards the construction of the clip 84, for cooperation in the manner of knives or shears to cut the length of yarn held between the

jaws

101 and 102 as later explained. On the other hand, in the arrangement of the clip 83 the cam-member 106 overlies the upper face of the plate 116 with a clearance therebetween so that these parts do not act as shears. The clip 83 carries a blade-like element 117 fastened to the inner face of the depending side of the mounting 100 and formed at its forward end with an arcuate extension 118 employed for a purpose later explained.

As before noted, the clip 84 is of substantially the same construction and arrangement as that of the clip 83 and corresponding parts are referred to in the drawings by the same reference characters. As shown in Figs. 11 and 12, the clip 84 is provided with means for opening its jaws 101and 102 without sliding the cam-member 106. For this purpose a cylindrical cam 120 is mounted to rotate on the stud 104. The end of the cam 120 is formed helically so that as it is turned on the stud 104 it will set against the rearward end of the movable jaw 102 to rock the latter; this end of the jaw being formed at an angle to its main portion to provide for the rocking action. A pin 121 projects radially from the cam 120 for rotating it to open the

jaws

101 and 102 of the clip 84 at the end of its travel whereby to release the yarn therefrom after it is clamped above the rotary tensioning drum described later. The pin 121 strikes against a fixed abutment 126 see Fig. 3, which acts to rotate the cam 120 to open the jaws of the clip 84 at the end of its travel.

Referring to Figs. 3, 5 and 9, the two

clips

83 and 84 are operated during the dofiing of the wound bobbin and the donning of an empty bobbin in the manner as next explained. The clips slide in

grooves

122 and 123 in the base of the framework of the winding mechanism, being moved toward and away from each other by the travel of the rolling carriage 87 under the operation of reciprocable bar 85. As the

clips

83 and 84 meet and pass each other they continue theirmotion to engage the yarn trailing from the dofied bobbin and cause it to enter between their jaws. The yarn is entered between the flaring ends of the

jaws

101 and 102 which are then closed together to clamp and hold the yarn. The closing of the jaws of the two clips is effected by sliding the cam-members 106 to cause them to release the movable jaw 102 on each clip and permit the spring 105 to force it against the fixed jaw 101. This sliding motion of the cam-members 106 is caused by their engagement with the beveled ends of a pair of

rails

124 and 125 extending horizontally along the base of the framework, see Figs. 3, 10 and 11. As shown in Figs. 10 and 11, the cam-members 106 have rounded side portions 111 adjacent their forward ends which engage against the beveled ends of the

rails

124 and 125 to slide the members rearwardly on the

clips

83 and 84. As the cam-members 106 are slid in this manner they are rocked laterally to release the movable jaws 102 of the clips for clamping action by the springs 105. As the

clips

83 and 84 continue their travel in opposite directions toward their stations the rounded side portions 111 of the cam-members 106 ride along the

rails

124 and 125 with the movable jaws 102 released thereby and acting to clamp the yarn y against the fixed jaws 101.

Referring to Fig. 9, as the clips pass each other the cam-member 106 on the lower clip 84 is slid by its contact with the end of the rail 125 to not only cause the closing of the jaws, but also to move the shearing edge of the cam-member across that of the blade 116 to sever the length of yarn y leading between the clips. In this way the yarn trailing from the dofied bobbin is severed from the end in the yarn-guide 25 so that it may be carried to the tensioning drum in the manner as later explained.

The retriever-clip 83 which has clamped the end of the yarn y leading down from the yam-guide 25 continues its travel to the left, as viewed in Fig. 9, and besides retrieving this end for attaching it to a newly donned bobbin b, it acts to return the yarn-guide 25 to initial winding position adjacent the head of the bobbin in the manner explained in the above-mentioned Patent No. 2,638,936.

Transfer-tail tensioning drum Referring to Figs. 6, 7, 8, l2 and 13, the tensioning drum which holds the end of the trailing yarn from the doifed bobbin is rotatably mounted in a recess or compartment 171 of the framework below the winding mechanism. The drum 170 is in the form of a sheetmetal cylinder supported by circular disks 172 and 173 i .7 at top and bottom. of its. interior... Projecting; fromthe. topgof the cylinder 170 are aserieslof. spaced. teeth 17.5 inclined-= outwardly: in: the formofv a comb. which. acts to catch-the yarncarried to therdrum by the clip 84, see Figs; 12- and-l3.

Iirorder to prevent the endtof the yarn y from pullingmuto'r; becoming detached from the. teeth: 175, means are provided for gripping it ata point within the confines of; the comb as shown in Figs; 1-2, 1-3 and l4. This detention means consists of. a flap-like gripper 1-76 having; cars at itsupper end pivoted on a'pinv 177 held in a bearing. member 178 fastened: to the framework at 179. A helical spring. 180- coiledaround the pin 177 has one end heldfast and its oppositeend 131 engaged against the gripper, see Fig. 14, to normally rock it downward 1y; The lower edge of the gripper 176 is adapted to engage against a resilient pad 182, constructed of spongerubber or the like, across the: top of which the yarn is drawn as it is carried toward the: right by the clip see Fig. 3; The yarn y is drawn under the lower edge of the gripper 176 as the latter is swung upwardly during the travel of the clip 34 toward the right as shown in Fig. 12. Pivoted on the pin 177 in the bearing 17% is a depending plate 183 with which the clip 84 first makes contact to swing it against the gripper 176 and liftthe latter for the passage of the clip thereunder. As the clip 84 approaches the end of its travel it passes beyond the gripper 176 and releases it to swing downwardly under the force of the spring 180 to pinch the yarn against the top of the pad 182 and resist its release from the drum 170. During the rotation of the drum 170 the fingers 175- of the comb will carry the yarn onto the periphery of the drum under the bailfltl, as shown in 5 Fig. 7, to hold it'under tension. The drum 170 preferably is covered with a roughened material such as fabric to prevent the yarn from slipping thereon. Means are provided for releasing the end or". the transfer-tail from the clip 84 after thelatter has connected the yarn to the drum 170. For this purpose an abutment 126 at the right-hand end of the framework, see Fig. 3, has a forwardly-projecting finger positioned to engage the pin 121 and rotate the cylindrical cam 120 to cause it to rock the movable jaw 102 of the clip 84 away from the fixed jaw 101 in the manner previously explained. W'hen the clip 84 is returned in the opposite direction for positioning it to pick up the. transfer-tail from the next doffed bobbin it must pass the gripper 176 and this is provided for by an opening 184 in the side of the grip per, see Fig. 14. During the further travel of the clip 84 to the left it strikes against the suspended plate 183 as indicated in Fig. 13 to rock the latter outwardly and pass thereunder. Means are provided for releasing the cylindrical cam 120 from the movable jaw 102 as the clip moves to the left toward its station.

For this purpose an abutment member 127 see Fig. 3, is adjustably mounted on the front of the framework by means of a. screw 128 engaging through a slot in said member. member 127 has a right-angular portion disposed to adapt it to strike against the end of the cam-member 106 on the clip 84 to slide the latter forwardly. The abutment member 127 also has a finger 129 proiecting forwardly from its end in position to strike against the pin 1-21. to rotate the cam 120 for releasing it from the movable jaw 102. In this way the parts of the'clip 8d are reset with its jaws open for engaging theyarn at the next forward travel of the clip.

therealong during the descent of the bobbin in the re serve magazine. It will be understood that as the bob bins. descend: in, the. reserve magazine; they draw. the transfer-tails. leading therefrom downwardly along; he. drum.170 so that upon therelease. of, each bobbin; from the magazine its; respective transfer-tail, is disengaged from, the drum: to adapt. it to be; caught and held for threading in the: eye of the loom shuttle; Thedrum 170. is. enclosed in a two-part cylindrical casing 189- comprising a rearward. stationary section 19.0 fastenedto. a wall of the framework by screws, 191, see Fig. 7. Attached to this part 0 of the casing 189 is, a, tubular bearing enclosing a pin 193, see; Fig. 6,011 which is hinged, the forward secti0n.195.- The section 195 is adapted to swing. outwardly to open the casing 189 for inspection of the drum 170. A. spring, not herein shown, or other suitable means may be provided for holding the, section of the casing 189 closed. The hinged section 195. of the casing 135" has. bearing lugs 196, see Fig. 7, at top and bottom for rotatablymounting the roller-bail .198 in contact with the periphery of the drum to press the. yarn thereagainst.

7 therebe'low and normally actuated from the reciprocation of the loom-lay, see Figs. 7 and, 8; The drum 170 is mounted for rotation on a vertical stud-shaft 200 journaled in a bearing in the base 201 of the compartment.

171 of the framework of the winding means. The studshaft prog'ects through a bore in the lower disk 173 of the drum 170 and the disk 172 at the upper end'of the drum is rotatable on a shouldered stud 202 projecting downwardly from a portion of the framework. Fastened against a boss or hub 203 on the under side of the lower disk 173 is a ratchet-disk 204 formed with relatively fine teeth on its periphery. The ratchet-disk 204 is rotatable on a bushing enclosing a shouldered portion of the stud-shaft 200 and is secured rotatively with the disk 173 of the drum by means of two pins 205 passing therethrough. A pawl 208 pivoted to a member 209 which is fast on the stud-shaft 200 is resiliently held in engagement with the teeth on the ratchet-disk 204 by means of a leaf-spring 210 fastened to'the member 209 at 211. Mounted fast on the lower end of the stud-shatt 200 is a triangular-shaped aim 212 carrying a pin 213 Fig. 7.

at it pointed end to which is connected a helical spring 214 anchored to a pin 215 fast in the base 201 and projecting downwardly therefrom. The triangular arm 212 has laterally-projecting pointed toe 216 at the opposite end from that connected to the spring 214. One edge of the too 216 is adapted for engagement by a roller 220 on an oscillatable lever 221 which is pivoted on a pin 222 projecting below the base 201, see Fig. 8. The arcuately-shaped edge of the other arm of the lever 221 is positioned for engagement by a hunter 223 fastened to the top or" the lay 2 of the loom. Through this arrangement the forward motion of the lay 2. causes the banter 223 to strike the lever 221 and rock it on its pivot 222. to engage its roller 220'with toe 216 and rock the triangular arm 212. As before noted, the arm 212 is fast with the stud-shaft 200 and thereby causes the pawl-carrying member 209 to be rotated therewith to retract the pawl 203 rearwardly along the teeth of the ratchet-disk Thus, when the hunter 223 recedes with the rearward stroke of the lay 2 the spring 214 will rotate the member 212 and advance the pawl 208 to rotate the ratchet-disk 204 and with it thetlrum which turns in contra-clockwise direction as viewedin This rotation is intermittent and continuous during the operation of the loom as effected by the reciprocation of the lay 2, the drum 170 being turned at a relatively slow speed since the pawl 208 is retracted only a few teeth at a time. To prevent reverse rotation of the drum 170a brake-shoe 225, shown in Fig. 7, as pivoted a t 2 .11% an eeeentric :taceengaseable with the interior of the drum cylinder. A leaf-spring a 9 227, shown in Fig. 7, tends to rock the brake-shoe 225 on its pivot so that normally it has substantially no braking effect against the interior of the drum cylinder when the latter is turned in the prescribed direction by the ratchetmeans. However, any tenedncy for the drum 170 to turn in the opposite direction will cause the brakeshoe 225 to dog against its interior to resist such rotation.

Means for accelerating drum-rotation It has been found of advantage to initially turn the drum 179 to a greater extent for insuring the attachment of the end of the transfer-tail thereto as the wound bobbin is held momentarily at the top of the reserve magazine. For this purpose a rockable lever 230 is pivoted at its upper end to a portion of the framework, see Fig. 6, to adapt its lower end to oscillate a horizontal lever 231 for actuating the ratchet-means described above. The lever 231 is pivoted on the stud-shaft 2% below the base 201 as shown in Figs. 7 and 8. The lever 231 carries a stud 232 projecting upwardly from its outer end with a convex-sided roller 233 journaled thereon and adapted to be engaged by the lower end of the lever 230. One side of the lever 23! is engageable with a lug 234 projecting upwardly from the triangular arm 212, see Fig. 6, whereby the rocking motion of the former will turn the latter to withdraw the pawl 2% a considerable distance rearwardly along the toothed periphery of the ratchetdisk 264.

The lever 23% is released by its actuating means at the end of the motion of the lever to the left as viewed in Fig. 6 whereupon a spring 228 connected at its lower end and anchored at 229 swings the lever in the opposite direction or toward the right. This latter movement of the lever 239 will release the lever 231 and allow the spring 214 to rotate the member 212 for advancing the pawl 203 to rotate the ratchet-disk 204. This action turns the ratchet-disk at a faster rate for rotating the drum 170 more rapidly to quickly draw the end of the yarn in the transfer-tail between the roller-bail 198 and the surface of the drum. In some instances it may be necessary to rotate the drum manually to wind on the end of a transfer-tail from a bobbin placed in the magazine and this may be accomplished by means of a finger-lever 235 shown in Fig. 7 as pivoted at 236 with its forward hooked end engaged with the roller 220 on the lever 221 which is operated by the hunter 223 on the lay of the loom.

The lever 236 is swung to the left as viewed in Fig. 6 by the traveling motion of the carriage 87 as it operates to traverse the

clips

83 and 84 for the purpose previously explained. For this purpose the carriage 87 has a projecting stud 240 at its end adapted to strike against the end of a slidable rod 241 carrying a collar 242 fastened thereto. The collar 242' is adapted to engage the edge of the lever 239 to rock the latter toward the left as viewed in Fig. 6 to stretch and load the spring 228. When the carriage 87 reverses its motion to travel back in the opposite direction the lever 230 is released to swing toward the rightand operate the ratchet-means in the manner as explained. As shown in Fig. 6, the lever 238 is connected by an angular link 243 to a bellcrank lever 245 pivoted in a casing 246. The bell-crank lever 245 is rocked by the lever 239 for actuating detention means for controlling the entrance of dofier bobbins into the reserve-magazine at the opposite side of the casing 246.

Reserve-magazine for wound bobbins Referring to Figs. 1, 2, 3, 4 and 5, the reserve-magazine for wound bobbins is similar in general to the construction used in conventional automatic looms. The present invention contemplates certain improvements for con trolling the entrance of each bobbin into the reservemagazine to detain it on a rest or shelf for an interval while its transfer-tail is being held and tensioned by the tensioning drum 170. The control means further provides for arresting the operation of the. winding means when the magazine becomes filled with bobbins. As shown more particularly in Figs. 4 and 5, the reservemagazine, indicated generally by the reference character 25%, is provided at the top with a hinged rest or shelf 251 which sustains each bobbin for an instant while its transfer-tail is held by the gripper 176 above the drum and attached thereto by the accelerated rotation of the latter. The shelf 251 is hinged to the vertical wall of the casing 246, previously referred to, to adapt it to swing downwardly to release the bobbin and allow it to drop down in the magazine 256. The wound bobbins B are thus supplied to the reserve magazine 250 in overlying relationship at the rear of the usual filling fork with the lowermost bobbin in position to be transferred to the shuttle by the transfer-hammer 252 shown in Fig. l.

Bobbin-detaining means The bobbin-detention shelf 251 is maintained raised in horizontal position by means of a lever 253 pivotally supported on a shaft 254 within the casing 246 and formed with a curved finger 255 projecting through. an opening in the forward wall of the casing with its end engaging the under side of the shelf, see Fig. 5. The lever 253 is held in the position shown in Fig. 5 with the shelf 251 raised by means of a spring 249 on its shaft 25%, see Fig. 6. After a relatively short interval the dotted bobbin B is released from the shelf 251 by the action of the mechanism contained in the casing 246, see Fig. 6, and previously referred to. The three-armed bell-crank lever 245, previously mentioned, has one of its arms 256 carrying a pin 257 engageable through a slot 258 in a vertical link 259. The upper end of the link 25? is pivotally connected to an arm 260 reaching outwardly from the lever 253 which supports the shelf 251. When the drum-accelerating lever 230 is swung to the left by the travel of the carriage 87 the connecting link 243 will rock the bell-crank lever 245 to cause its arm 256 to raise the vertical link 259 and thereby rock the lever 253 to withdraw its curved finger 255 from under the shelf 251. The shelf 251 is thereupon allowed to swing downwardly to release the bobbin held thereon and cause it to drop by gravity to the magazine 250. Clamping means, to be described in the continuing application referred to above, are provided for engaging the heads of the bobbins to hold them from turning in the magazine, the clamps being released automatically to permit the bobbins to slide down in the magazine as each lowermost one is transferred to the shuttle of the loom.

Full-magazine control for stopping winding means The bell-crank lever 245 which operates the lever 253 to release the detention-rest or shelf 251 also has another function, namely, to arrest the operation of the winding means when the reserve magazine becomes filled with wound bobbins. The stopping mechanism for the winding means may be either mechanically or electrically operated and as herein shown a so-called micro switch 275 is employed, see Fig. 6, for opening the circuit to the electric motor which drives the winder. The switch contains contact members for closing the circuit and by actuating it the circuit is opened in the usual way. For this purpose a rockable arm 276 is connected to the upright arm 277 of the bell-crank lever 245 with its forward end formed with an arcuate campiece 273. The cam-piece 278 is adapted to ride against a roller 279 on an arm 280 projecting from the side of the switch 275. The arm 276 is formed with a longitudinal slot 281 slidably engaged by a pin 282 projecting from the vertical link 259 which controls the position of the bobbin-detention shelf.

Normally, when the link 259 is raised by the rocking a. 11 Pit b out ts st 5m elease the leve 25? from tli e lf ZSLi the arm276 will be slid to the right as yiewe in Fig; 6 so that its cam-piece 278 will clear the roller 2 79 connected to the switch 275. Qonsequently, the circuit will remain closed to supply current to the winder. When, however, the magazine 250 becomes filled with bobbins and the last-entered one holds the shelf 251 depressed the above-described mechanism will function to operate the switch 275 and open the circuit to interrupt the flow of current to the motor; thereby arresting the operation of the winding means. This last described action is caused by the link 259 being lifted and held raised through its connection at 26G with the shelf 251 when the latter remains depressed by a bobbin resting thereon. As the bell-crank lever 245 returns to its rest position shown in Fig. 6 the arm 2.76 is slid to the left, and due to said arm being held in raised position by the link 259, as permitted by its pin-and-slot connection with the lever 245 at 281, 232, the cam-piece 278 on the arm engages with the roller 279 on the switch: lever 280 to actuate the switch 275 and open the circuit to the winder driving motor. The switch 275. is thereby operated to open the circuit to the motor and arrest the operation of the winding means until a bobbin has been transferred from the magazine 250 and the bobbins thereabove lowered to release the shelf 251. As the shelf 251 is released and the parts restored to first position the link 259 drops to the position shown in Fig. 6 and thereby rocks the arm 276 downwardly to remove the cam-piece 278 from the roller 279 to permit the switch 275 to operate to close the circuit to the motor and restart the winding means. 'Means are also provided for releasing the clamping means in the magazine to free the bobbins so that they cannot jam therein and prevent the release of the bobbin detained on the shelf 251. Such means are shown at the right in Fig. 6 and described in detail in a continuing application to be filed later.
