Said pin affords a pivotal connectionV between the cam-driven `linlr Vt* 46 and` the*VV slotted vibratory arml 36so that the motion of eccentric 44and link 46 operateV to automatically impart the vibratory motion to the slotted arm 36, which through the Vrock-- shaft 17 imparts motionvto the other vibraV toryarm 37, which arms 36, 37 Aimpart the reciprocatorj'fV motion tov ther plaiting blade 38. The pivotal pin 48Vis.. shiftable` in the.
other end of which link is loosely connected with the shiftable pin i-8.' Movement of the.
lever in one direction operates the link 51 so as to draw the pivotal stud 48' toward the aXis of movement of the vibratory arms,
thereby increasing` the stroke of the plaiting blade, but it is apparent that the lever` 50 can be shifted in an opposite direction for the purpose of moving the pivotal pin -l- S away from thev axis or" movement of the arms 36, 37, thereby decreasing the stroke'oi? the plaiting blade, such variation in the stroke of the plaiting `blade being effected by a manual adjustment of the parts, whereas the came-.lt and shaft 19 impart automatic movement to the plaiting blade. The lever 50 is adapted-to be liXed in either one of" ated, as shown in Fig. 2, so as'to determine the position of the lever 50 according` to the character ol the side plaits to be .termed in the material. by the movement of theplaiting blade l will now proceed to describe the means for imparting movement automatically to the heatable roll 16 for the purpose of ieeding the plaitedmaterial vfrom the table 20 to the inclined plate or table 23, the extent of angular movement of said roll being variable in accordance with the vvariable stroke 'of the plaiting blade 38, and such variable movement'being imparted to the roll 1G simultaneously with the variable movement given to the plaiting blade 38, all being-controlled by the lever 50. j
'lf he roll 16 at the end opposite to thehun.- sen mixer 31 is provided withl a wheel 55, the diameter of which is considerablyv in excess oi:A the roll, and the periphery of 'which is 'formedV with a multiplicity olf line ratchet teeth 56, the number of ratchetteeth in iny nntchine being` largely in excess of the teeth on ratchets ol other machines oiz which have knowledge. The :ratchet wheel is secured rigidly to the journal 27 at one end eff the roll, and lccsely sleeved upon ythis journal is lever arm 57 the position of '72 se ast-o raise er leu .i
which is indicated by dotted lines in Fig. 17 said lever armbeing provided with a strap, indicatedfin dotted lines 'at-58, which. is loosely itted around the jeurnal or around the hub of the ratchet, wherebyy thelever arm 57 is capable oi' vibratory movement r-.round the axis ot' a ratchet wheel 55. The lever arm' is provided with a stud er pin 59 onv whichis supported a 'feed 'pawl 60, said leed pawl being held .by a spring 61 normally into' engagement with one tooth of the ratchet wheel 55. The pin 59 is litted loosely in a slot 620i an'upright segment G3, which lies alongside o the ratchet wheel 55, and te the upper end of this segment is pivoted a driving link 64; provided at one end with a strap which is itted loosely around an'erccentric G6, the construction of which illustrated morepar 'icularly in .lli s. 5, 6 and 7 of the drawings. Said er'centric is provided with a stud 67, the. axis of the latterheing :it one side of thel axis of the eccentric7 Fig. '7. 'Said stud enters a socket 58 ol a lcani head 59, the latterv bein0` secured rigidly to an end portiongol the drive sha'l't 19 so as to'i-otater therewith. The h ad is provided with bind` ing screw 70 which is tapped into the threaded Opening of the head and is adapted for :frictional contact with., the stud A67, whereby the stud 67 and the eccentric 66 are clamped rigidly tothe head 69 for rotation with the sliaict'lf). lt is 'apparent that the shait 19 and head 'G9 impart rotary m0 tion to the'ccrcntric G6 because the lati'er is "clamped `by the screw T() rigidly to the'head, and said cam acts through the s .up and link (ill, to impart vibratery 'inetion to the Veglnent (33, the lower nid oi: which is piv- 'otally supportedby a bolt 7l attached to" the 'free end ol' :r rocker arm 72 which is clamped by a screw 73 upcn an cndportiou of the rockslntl't 18, to which is attached the controlling lever 50. Said holt 71 con# stitutes the axis oli movement of' segmentv G3, the vibratory 'in'oticn oiv'which `under the; action of came?)

This motion is automatic under the action el means operated by the eccentric (lith-but the ..z-'ztent olrotation angle ot movement) oi" the ratchet and the roll l@ are capable of variation by itment, lirst7 of the ment G3 and the eccentric 61"), Said segment 63 controllable `by the movement o' lever 50 which rocks the shaft l13 and lever n the segment r tively tcy the pawl pivot 59 soas to vary the v Vso distance between the pawl pivot and the axis of movement (bolt 71) of the segment, thus making provision for effecting a varia; tion in the throw of the pawl andthe movement of the ratchet, Yit being possible to rotate the ratchet by movement of the segment so asto feed it a distance equivalent to two,three, four or more teeth according to the widthV of the Aside plait. lVith the lever held in its first position and with accordion plaiting, and the position of thel eccentric to the cam head is indicated to the operator by an index disk 75, which turns loosely on the studv 67, saiddisk being con- .nectedV to the eccentric by a pin 76 on the diskfitting `in a hole 77 of the eccentric (see F igs. 5 to 7 inclusive), and said disk having a pointer 78 projecting beyond the peripheral edge of theecce'ntric so as to 'traverse suitable marks on the cani head.
After adjusting the eccentric, the screw is tightenedfand the eccentric strap. 65is replacedl on the eccentric so that the latter will act through the driving link 64 in automatically operating the segment for actuating the pawl and ratchet so as to rotatel the feed roll 16. l
Said feed roll 16 is provided with a gear 79 (see dotted lines in Figa. 1), with which meshes aA gear 8O on the cooperating feed roll 15, said gears operatingto transmit the rotative movement of roll 16 to the companion roll 15 for the purpose of feeding the.v fabric betweenrthe rolls, at which time the heat and pressure of the rolls operate -to flatten and setv the plaits inthe fabric.'
The rocking bar 43 by which the plaiting knife 38 is mounted on the vibratory arms 36,37 is capable of a back and forth motionv with said varms so as to impart reciprocatory vmovement tothe plaiting blade,
but this rocking bar and the plaiting blade are capable ofindependent pivotal movement in order that said blade may on its effective .plaiting stroke be positively depressed under camV pressure into contact 'Y withthe Vmaterial or materials, whereby the blade ispositively actuated so as to plaitV the fabric and one or more layers of paper. The cam head 69 is providedl with a cam surfacej81, the contour of vwhich is indicated by dotted lines in Figs. 1 and 6, upon which 'cam surface rides afriction roll 82 mounted loosely on an end portion of a s position indicated in dotted lines in Fig. 4
AThe free ends of levers 92 are engaged'adjustably by threaded rods 941of springs 95,
thus making provision for applying spring f pressure to the Yupper roll, the tension of the springs being capable of regulation by adjusting suitable vnuts 96a on the rods V94,- see Figs. `1 and 2. Y Y
For the purpose of lifting the upper roll 15 vfrom contact with the lower roll, I provide a yoke96, the arms of which are pivotedat 97 to the tension levers 92, said yoke having.
al handle 98 and the arms of the yokebeing provided attheir ends with s tuds'99`V positioned to ride upon the top portionsof the Vend frames 10,11. With the yoke in the in clined position of Figs. land 2, the levers 92 are under the tension of the springs95 to apply pressure .to the roll 15, but the operator is able to shift the yoke to the vertical thereby .raising the levers Y92, the sliding bearings 14 and roll 15, said yoke-operating to retain the roll in said raised position.v Means are providedfor rotating the rolls 15, 16 independently Vof the Vcam-actuated pawl and ratchet feed, vso thatan unplaited or plain fabric may befed through and by Vthe rolls in order to separate two or Vmore plaited portions of thefabric by' one or more Y unplaited portions of said fabric. To this "end, a hand lever-100 vis, loosely connected byl a ringl 101 to an end0 .portion of roll 15,'seeFig. 1, sothatthelevermay turn part way around the roll with the latter as the axis ofmovement of the lever; A feed,

By placing the tension and guide devices over fthetable` and adjacent to the blade 38 the fabric can be kept taut 'clear to vthe end of the fabric. l i
ln addition to .feeding'the'fabric to the plaiting blade, means are providedforfeeding papertol saidblade,l one strip of paper Z being shown in Fig. 4 as passing over the table 20 and belowthe fabric X, but itis apparent lthat an additional strip; (not shown) can, be fed Vover the fabric, where by one or more strips vof 'paper'km'ay be plaited withthejfabric bythe voperation of bladev 38.y The stripgor strips Aof paper do not pass through the tension device',` 'The underlyingk paper keeps the:fabricffromdi-L Y rect contactrwith the heatedroll16-s0 las to preclude.scorchingthe fabric, and theoverlying paperprecludes the rollsfrom Vimparting a Aglossyappearance -to fthe-surface of the fabric.

.The operation'is asfollows-ssuming" itlis desired to producegside plaitsrin a piece of; fabric, Vwhich.

tinued as long as desired Vand 'without change of parts to produce plaits of a, de-` sired Awidth andv 'overlap in the fabric. Should -it be vdesired to decrease the width of lthe plait or the overlap thereof, then the lever`50'ismoved lin one direction 4and held in such positionby the` screw bolt, the
effect of which movement is to shift the pin 48 Vand to shift thesegment 63 at one and stroke of the blade 38y andfchanging also VVthe extent of rotative movement of the feed roll 16upon the Vsubsequent operation of the machine bythe cams 44,66; but should it be VVdesired to increasethe plait or the overlap thereof,rthen the'` lever v50. is moved in an opposite direction, thusreversing the ad v`justmentfof parts 48, 63 so as to correspondingly affect the plaiting blade 38v and the feed roll 16. j
For producing accordion plaiting inr the fabric", the lever 50 is adj usted'` to a position vwherein' the blade. 38 is moved the desired distance, but the member 66 of the double' cam 6669iis shifted byjreleasing screw 70 and changingthe'cam member66 relatively tolthe head 69, the index disk being movable 46 imparts the desired stroke to the blade i the blade 38upon the effective stroke there- The operationiscony vthe ,same operation, thus 'changing Vthe with the "cam member 66 to the desired position, after which the screw 70 istightened and the'parts restored tovoperating Ypositions. v'Now .when lthe shaft 19 is rotated,
`theV several parts'of the machine are operatedas before, butthe cam member66 oper- Y atesthe segment and pawlso as toA feed the *Y fabricy one tooth of the ratchet at a time,
Vsothat there isa uniform feed of the fabricto produce the accordion plaiting, the width of the'nlaits being variableby adjustment of lever 50l which controlsnthe operatingv devices for `the *plaiting blade and thefeedroll. f Y Y Thelever arm .83 Vcontrolled by 'the rock shaft 18 acts to bring the two cams 44, 66, onthe power shaft into synchronism,where bythe changesin the depression and lifting motion of the' plaiting blade and in the feed Vand speed'motion of the' rollers are brought f into unison, which motion requires one setting of the lever 50 instead-of independent i' adjustment of the pins 48, 59. It is apparent 'that the shifting ofthe pivotal pin 48 inthe slotted arm 36 Vresultsalso in'a shifting of the pivotal connection `59 in the slotted's'egment v63, but. this change leaves the relation Vof the cams 44, 66', unchanged and the automatic 'drive would have a tendency vto )vork out of time; butin lmy machine, thev leverv arm 83'is voperatedV from theV shaft. 18 at the time that-the pins 48, 59A are shifted so that the relation Vof the roller 82 to the cam surface 8l is: shifted in order that the cams 44, 66, will operate properly .vith'out resetting either of saidlcams'44, 66.
