The cam plate 250 comprises a central portion 251 having a central opening 252 through which the shaft 6 freely extends. 253 indicates a portion depending from the central portion 251 and terminating in an enlarged portion 254 provided with a concentric slot 255. 256 indicates a screw having an enlarged head, the shank of the screw extending into the base plate 1 and the head bearing against the outer face of the enlargement 254 thereby securing such enlargement in a stationary position against the end of the base plate. 257 indicates a cam piece extending upwardly from the central portion 251, the upper edge of such cam piece being concentric with the center of the shaft 6 and flush with theouter periphery of the disk 244, the upper corner of such cam 6 being preferably chamfered off at 258. 259 indicates a gravity dog carried by the arm 243, the depending portion 259 of which is provided with a lateral extension 260, which extension is designed to be brought into engagement with the upper peripheral edge of the cam plate 257 so as to carry the depending portion 259 out of the notch 246. The arm .243 is provided with a hollow portion 261, such hollow portion being provided with longitudinally alined slots 262 and 263. The upper end of the arm 243 is provided with a jaw portion 264. 265 and 266 indicate gripping jaw members. The member 266 is mounted on a cross pin 267 passing through the jaws 264. 268 indicates a tail piece formed integral with the jaw portion 266, such tail piece being provided with a slot 269 provided with an enlargement at its lower inner end forming a shoulder 270. 271 indicates a bracket carried by the arm 243. 272 indicates a finger pivotally connected at 273, the end of such finger extending below the pivot point being provided with a spring finger extensi on 274 designed. to bear against the arm 243. The upper end of the finger 27 2 fits into the slotted enlargement forming the shoulder 270. 275 indicates a tension spring connected at one end to the extreme end of the tail piece 268 and at the opposite end to the jaw 273. 276 indicates a cam plate comprising a bar portion 277 formed concentric with the center of the shaft 6 and having at its inner end a radial enlargement 278 having an inclined inner edge portion 279 and a lateral extension 280 provided with an inclined portion 281. 282 indicates a bracket provided with a sleeve-like portion 283 extending at right angles to the edge of the plate 5 and to the outer end of which a cam plate 276 is secured by means of a screw 284 extending through the portion 283 and cam plate 276. The bracket 282 is adjustably secured to the plate 5 by means of a set screw 285 extending through the bracket 282 and an arc-shaped slot 286.

It will be understood that as the arm 2 13 swings into the position shown in Figs. 4 and 5 that the cam plate 276 passes between the arm and the finger 272 carrying the ger 272into engagement with the inclined portion 281 forcing such finger outwardly against the pressure of the spring 27 1- so as to carry the opposite end of the finger clear of the shoulder 270 allowing the jaw member 266 to be drawn downwardly by means of the tension spring 275, the finger 272 passing through the slot 269. As the arm 2 13 swings in the opposite direction or toward a vertical position the tail piece of the jaw 266 engages with the inclined portion 279 of the cam plate enlargement 278 thereby carrying the tail piece upward and restoring the jaw member 266 to its normal position, the finger 272 being simultaneously carried again into engagement with the shoulder 270 by means of the spring 27 1.

287 indicates a pin extending inwardly from the arm 2 13, such pin being located at the lower end of the slot 262. The jaw member 265 is provided with a shank 288, which fits into the hollow portion of the 2 :3. 289 indicates a pin extending outwardly from the shank 283 through the slot 263 and, therefore, in longitudinal alinement with the pin 287. 290 indicates a compression spring extending between the bottom of the hollow member 243 and the lower end of the shank 288. 291 indicates a stud extending out wardly from the bracket 201, the outer end of the stud being formed into a jaw through which extends a pin 292. 293 indicates an arm swung upon a pin 292. 2941; indicates a tension spring connected at one end to the lower end of the arm 293, and at the opposite end by suitable means to the bracket 201. The upper end of the arm 293 is provided with an enlargement 295, which is spearshape in form, the tip of the spear being slightly bent inwardly at 296. It will be noticed that the arm 293 forming the shank of the spear is located at one side of the head and immediately below the center portion of the head is formed a channel portion 297. As the arm 2 13 is swung over to the opposite angular position to that shown in the drawing the inturned tip of the spear head engages the inner face of the arm 2 13 and is slightly forced inwardly and passes between the pins 239 and 287, such pins en gaging the upper and lower edges of the spear head and being gradually spread apart thereby or, in other words, the pin 239 is forced downwardly in the slot 263 carrying the jaw member 265 away from the jaw member 266. lVhen the pin 289 has passed the lower end of the spear head the jaw member 265 is forced outwardlv by the compression spring 290 thereby car .ng the pin 289 toward the pin 23'? and into circumferential. alinement with the bevel portion 297 of the spear head so that when the arm 243 is again swung back toward the position shown in the drawing the pin 289 engages such bevel portion forcing the head 295 inwardly against the tension of the spring 29 1 thereby allowing the pin to pass.

298 and 299 indicate vertical ways formed in the back of the plate 5. The upper end of the way 299 is provided with an opening 300 for a purpose which will hereinafter appear. The way 298 is dove-tail in form and provided with a vertical casing 301 extendin vertically of the front face of the plate 0. 302 and 303 indicate standard plates extending inwardly from the plate 5, the plate 303 being carried by an inward extension 30 1 and the plate 302 by the wall of the casing 301. indicates a slide provided. with a dove-tail portion 306 slidably held within the way 293. 30'? and 30S indicate vertical grooves formed in the slide 305 and extending from the top to the bottom of the same. 309 indicates a bar piece fitting within the vertical groove and pivotally secured therein at its lower end by a pin 310. The slide piece 305 is provided at one side with an upward extension 311 provided with a vertical slot 312 open at its upper end. The piece 309 is provided at its upper end with a lateral extension 313 terminating in a forwardly extending portion 31 1 passing through the open end of the open ended slot 312. 315 indicates a piece slidably held in the groove 307 and 316 indicates a notch formed in the lower end of the slide piece, such notch forming a lateral extension of the vertical groove 30?. 317 indicates a portion extending forwardly from the lower end of the piece 315 so as to protrude through the notch 316. 318 indicates a tension spring connecting the portion 317 with a stationary pin 319. 320 indicates a lateral extension to the upper end of the piece 31:), such lateral extension terminating in a for\ "a rd extension 321, such forward extension being provided with an upwardly extending notch 322 at its lower en d.

indicates a saw cut formed in the upper end of the slide piece 305 and forming a lateral extension to the groove 30?. 3241 indicates a tongue extending forv-Jardly through the saw cut 323, such tongue being provided with an inclined upper edge 325. indicates a vertical slot formed in the side of the casing 301. 327 indicates a bell crank piece pivotally mounted on the plate 5 to the outside of the casing 301 in such a position that the horizontal arm of the bell crank protrudes through the upper one of the slot 326 into the casing 301 the lower end of the vertical portion of the bell crank 327 bearing against the lower end of the slot 326 being held thereagainst by a compression spring 328.

It will thus be seen that as the slide piece 305 passes upwardly the inclined portion 325 of the tongue 324 engages the horizontally extending portion of the bell crank 327 which is held rigid from upward movement and thereby forces the pivoted piece 309 outwardly from the slide piece at its upper end and thereby carrying the inward extension 313 out of the path of the cord which is being fed on to the top edge of the plate 5.

328 indicates a plate which is secured to the outer face of the slide piece 305 and extends over the outer edge of the vertically movable piece 315 thereby holding such piece in place. 329 indicates a leaf spring which is carried by the plate 328 and bears at its upper end against a laterally extending portion 313 of the pivot piece 309. It will thus be seen that when the tongue 325 has passed in its upward vertical movement the horizontal arm of the bell crank 327 that the pivot piece is forced back to its normal position carrying the extension 313 into a position over the cord carried by the upper edge of the plate 5. 330 indicates a projection extending inwardly from the casing 301 into the guideway 298 so as to be vertically in the path of the inward extension 317. As the slide piece passes to its uppermost position the extension 317 engages with the projection 330 thereby forcing the piece 315 downwardly against the action of the spring 318 and carrying the inward extension 321 away from the inward extension 313 into the position shown in Fig. 27. 331 inclicates a block provided with an inclined upper edge 332, such block being preferably adjustably held in position by a set screw 333 passing through a vertical slot 334 formed in the wall of the casing 301.

It will thus be seen that as the slide passes downwardly to its lowermost position the tongue 324 engages with the inclined portion 332 of the block 331 thereby again swinging the pivot piece 309 away from the guide piece 305 against the tension of the spring 329 so as to again carry the inward extension 313 out of the path of the cord. 335 indicates a cord carrier. 336 indicates an arbor journaled in the opposing plates 302 and 303, the central portion of the arbor being preferably rectangular and extending through a correspondingly formed orifice in the carrier 335. 337 indicates a guide secured to the upper end of the carrier 335 and provided with opposing guides 338 and 339. The base of the guide 337 is cut away at 340. 341 indicate a pair of spring fingers secured to the shank of the carrier 335 and extending upwardly beneath the cutaway portion 340. Each of the spring fingers 341 carries a curved portion 342 at their upper end normally hearing against the upper walls of the guides 338 and 339. 343 indicates a spring finger also secured to the shank of the carrier 335. The spring finger 343 extends upwardly beneath the spring fingers 341 and past the end thereof and is provided with a cross bar 342 provided with open eyes 343 and 344 through which the ends of the cord portions are drawn as hereinafter described. 343 indicates a pinion mounted upon one end of the arbor 336. 345 indicates a vertical guideway carried by the plate 303. 346 indicates a rack bar slidably held in the guideway 345 and in engagement with the pinion 343. 347 indicates a bell crank lever mounted upon a standard 348 carried by the base 1. 349 indicates an arm provided with an annular upper end 350 swung upon the shaft 6. 351 indicates a link connecting the depending end of the arm 349 to the lower end of the depending portion of the bell crank 347. 352 indicates a link pivotally connected at its lower end to the horizontal end of the bell crank 347 and provided at its upper end with a curved portion 353 pivotally connected at its extreme end to the lower end of the rack bar 345. 354 indicates a cam secured to the shaft 6 from the inner face of which extend pins 355 and 356.

It will thus be seen that when the operating lever 7 is swung in the direction of arrow that the pin 356 is carried into engagement with the arm 349 thereby drawing the arm in the direction of arrow and tilting the bell crank 347 on its pivot and raising the link 352 and rack 345 in mesh with the pinion 343 thereby swingin the carrier in .the direction of arrow (see l ig. 2). When the lever 7 is swung in the opposite direction, of course, the pin 355 engages the arm 349 to perform the reverse operation, that is to say, swing the carrier in the opposite direction of arrow back to its normal position I will now describe the mechanism by which the guide piece 305 is raised and lowered in the guide way. The guide piece 305 is provided with a lug extension 305*. 357 indicates a linkpivotally connected at one end to the lug extension 305 358 indicates an arbor journaled in a lug extension 359 of the plate 5. To one end of the arbor 358 is secured an arm 360 to the inner end of which is pivotally connected the lower end of the link 357 above described. 361 indicates an arm secured to the opposite end of the arbor 358. 362 indicates a cam way formed in the cam 354. 363 indicates a link pivotally connected at one end to the arm 361 and at the opposite end to a link 364, which is pivotally connected at 365 to the base 1 of the machine. The pivot pin connecting the links 363 and 364 together carries a roller 366, which co-acts with the cam groove 362. It will thus be seen that when the cam 354 is turned in the direction of arrow (see Fig. 4) that the cam roller 366 is carried outwardly toward the periphery of the cam and that, therefore, the arm 361 is carried in the direction of arrow carrying the arm 360 downwardly and thereby drawing the guide piece connected to the arm by the link 357 downward. 367 indicates a pin carried by the guide piece 305. 368 indicates an arm swung upon a pin 369 carried by the casing 301. 370 indicates a slot formed on the wall intervening between the casing and guide 298. 371 indicates a horizontal extension to the arm 368. 372 indicates a tension spring connecting the arm 368 to the opposite wall of the casing 301. It will thus be seen that when the slide piece 305 is carried verticallv downward that the arm 368 allowing the arm to be swung on the pin 369 to carry the lateral extension 371 thereof through the slot 370 and thereby free the carrier 335 to swing in the direction of arrow as above described. 373 and 374 indicate slots formed in the plate 5 in proximity to the outer edge thereof. 375 and 376 indicate brackets secured to the sides of the plate by set screws 377 extending through the slots 373 and 374. 37 8 indicate spring fingers secured to the bracket 375. 378 X indicates a spring finger secured to the bracket 376 by a rivet 377 379 indicates a set screw extending through the bracket and bearing against the outer face of the spring finger so as to adjust the tension of the finger upon the cord. The fingers 37 8 and 378 x may be provided with out-turned lip extensions 380 so as to allow of the ready entrance of the cord therebetween.

In Fig. 31 I have shown a detail view of a mantle showing the cord 209 threaded therethrough.

Having described the principal parts involved in my invention I will briefly describe the operation of the same.

Before operating my machine a mantle is passed over the upper end of the plaiter 37, the lower edge of such mantle being passed downwardly to between the outwardly flaring plates 128 and 129 or into the position shown in Fig. 18.

When the lever 7 is thrown in the direction of arrow the shaft 6 and earn 8 carried thereby are rotated in a similar direction. During the initial movement of the cam 8 the roller 35 travels through the concentric portion of the cam groove before it enters the spiral portion. During this movement of the roller the needles 21 and. 22 are held stationary.

During the initial movement of the lever 7 as above described the cam 106 is rotated in the direction of arrow (see Fig. 10) thereby drawing upon the link 123 and slotted arm pin passes clear of the 110. This operation rocks the counter-shaft 100 inwardly thereby swinging the arms 103 and l04'downward drawing the links 105 downward and the blocks 96 downward in the guideway 50. The downward movement of the blocks 96 draws the cross bar 61 downward in the vertical grooves 58 of the blocks 54 thereby rocking the bars 63 inwardly and securing the hooks 200 into the grooves 43 and into engagement with the mantle. Simultaneously with this operation the cam 156 is rotated in the direction of arrow thereby forcing the roller 157 downward and thereby carrying the slotted link member 149 and rack 150 connected thereto in the same direction thereby rotating the pinions 79 and 80 to swing the two sets of arms 81, 82, 83, 84, 85, 86, 87 and 88 inward toward each other into the position shown in Fig. 22 and into engagement with the mantle in proximity to the lower edge of the infold a forming the hem and thereby forming the plaits.

As this operation is performed the cam 165 is also rotated to draw down the loop member 142, which pulls upon the rod 139 carrying down the slotted head thereof in engagement with the pins 136 and 137 thereby tilting the plates 128 and 129 inward into the position shown in Fig. 19.

As the bar 61 is drawn down it pulls upon the pawl heads 69 of the bars 63 which are carried by the blocks 54 thereby exerting a pull on the blocks so as to overcome the spring 59 drawing the block past the spring and thereby carrying the bars 63 and hooks 200 carried thereby downward or from the position shown in Fig. 20 to the position shown in Fig. 21. By this downward movement the sides of the mantle are drawn down past the lower edge of the mantle so as to form an upward inwardly extending hem as shown at a in Fig. 21. Also simultaneously with the above operation the cam way 225 (see Fig. 4) is carried in the direction of arrow thereby carrying the roller 232 into the concentric portion of the cam way and thereby raising the knife 210 into position ready for cutting. During this operation the pin 249 engages the arm 243 swinging it upward and past a vertical position until brought into engagement with the roller 240 thereby depressing the corresponding end of the arm 238 against the pressure of the spring 241 thereby carrying the oppositely extending arm 239 in an upward direction to carry the slide piece 215 circumferentially of the plate 5 and thereby feeding the cord 208 which is gripped by the spring ratchet finger 221 through the perforation 206 into position to be gripped between the jaws 265 and 266.

As has been before described when the arm 243 approaches this position the head 295 enters between the pins 289 and 287 spreading them apart and drawing the jaw 265 away from the jaw 266 thereby allowing the fed end of the cord protruding through the head 203 beneath the knife 210 to pass between the jaws 265 and 266. As the pin 289 passes the base of the head 295 such pin is released and the jaw member 265 is forced by the spring 261 against the jaw member 266 to grip the cord therebetween. By the upward movement of the lever 7 in the direction of arrow the cam 354 is rotated carrying the roller 366 outwardly in the cam groove 362 toward the periphery of the cam thereby forcing the link 363 longitudinally outward and swinging the arm 361 in the direction of arrow. .The outward swing of the arm 361, which is carried by the arbor 358, serves to carry the arm 360 also carried by the arbor 358 downward drawing upon the link 357 and carrying the guide piece 305 downward to the dotted position shown in Fig. 6.

It will, of course, be understood that this initial downward movement of the slide piece 305 is an idle movement as the cord has not yet been fed to the machine into engagement therewith. By the same movement also the pin 356 is carried into engagement with the arm 349 swinging the min 349 in the direction of arrow and drawing upon the link 351 tilting the bell crank 347 on its pivot raising the link 352 and rack 345 in engagement with the pinion 343 thereby swinging the carrier 335 in the direction of arrow in an idle movement.

As has been before described the plaiting arms 81, 82, 83, 84, 85, and 86 are rigidly held upon their supporting shafts, the arms 87 and 88 being resiliently held by the spring lingers 92 and 93. It will also he noticed that the ends of such arms project forwardly of the remaining arms and are, therefore, brought into contact with the center portion of the mantle before the remaining arms thereby drawing the lower hemmed edge of the mantle toward the center of the mantle to take up the slack. The remaining fingers then engage with the mantle forcing the remaining portion into plaited form and drawing the ends of the arms 87 and 88 back into alinement with the remaining arms so that the eyes of all the arms are in longitudinal alinement. As soon as the plaiting arms have assumed the position shown in Fig. 22 the roller 35 enters the spiral portion of the cam groove 9 of the cam 8 thereby swinging the lever 13 forward and the needles 21 and 22 forward so as to pass longitudinally through the eyes 94 and 95 and into the grooves 187 so that the slotted openings of the eyes are immediately above the slots 190 and 191. As the eyes of the needles assume this position the cam 156 has been rotated so that the gravity dog 176 drops into the recess 158 rocking the shaft 175 carrying the gravity dog downward and swinging the arm 178 upward, such movement being assisted by the tension spring 179. By means of the link 198 connected to the arm 178 the block 182 is carried upward carrying the ribbon fingers 195 and 196 through the eyes of the needles, the extreme ends of such fingers spreading outwardly after their passage through the eyes into the form shown in Fig. 17. As the arm 243 is swung in the direction of arrow (see Fig. 5) the gravity dog 259 passes off the periphery of the cam plate 257 and engages the notch 247. lhe operating lever 7 is then swung in the opposite direction to arrow. By this movement the disk 244 is rotated in the opposite direction of arrow so that the notch 247 engages the pawl 259 by carrying the arm 243 in the opposite direction to arrow. As has been before stated the cord 208 has been gripped between the jaws 265 and 266 and therefore, asthe arm 243 swings in the reverse direction the cord is drawn through the perforation 206 around the peripheral edge of the plate 5 toward the opposite side of the plate. As the lever 7 assumes its final position and the arm 243 has reached the position shown in Figs. 4 and 5, the roller 235 again engages the eccentric portion 227 to the cam way 225 thereby drawing the pitman 234 downward and swinging the knife 210 downward to sever the fed portion of the cord from the stock, the arm 243 finally carrying the severed portion of the cord into the position shown in Fig. the arm 243 reaches this position the jaw member 266 is released by means of the finger 272 engaging the inclined portion 230 of the cam plate as has hereinbefore been d scribed thereby releasing the cord. Also by the reverse movement of the lever 7 the carrier 335 is swung back to its normal position or the position shown in the drawing, and the guide piece 305 raised. In order that the inwardly projecting portion 313 should pass the cord carried by the upper edge of the plate 5 as the guide piece 305 assumes its uppermost position, the tongue 325 engages the horizontal portion of the arm 327 thereby forcing the member 307 outwardly on its pivot against the pressure of the spring 329 thereby allowing the inwardly projecting end 313 to pass the cord. It will, of course, be understood that the cord bridges the open upper end of the opening 300 when it is in position on the upper edge of the plate 5 and that the inwardly projecting portion 321 is drawn downward so as to extend directly beneath the cord, such downward movement/being imparted to the member 315 carrying such inwardly projecting portion by the spring held portion 317 engaging the inward projection 330.

As the tongue 324- passes above the hori-
