JULIUS ARANYOSSY, OF NEW YORK, N. Y.

PLAITING-MACHINE.

Application filed October 17, 1916.

To ai? whom t may concern.'

Be it known that I, JULIUs ARANYOSSY, a i citizen of the United States, anda resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Plaiting-lifachines, of which the following is a specification.

This invention relates to a plaiting machine of novel construction which is'adapted to fold a strip of textile fabric into knife plaits, accordion plaits or box plaits. The machine comprises essentially, a pair of intermittently rotating rollers (one of which is heated) through the pass of which the strip is fed so as to be laid into folds by means of the alternating forward and backward partial rotation of the rollers..A The rollers operate in conjunction with a pair of reciprocative knife blades, which are made to enter the folds during their formation, so as to form a flat core around which the fabric is doubled. For making knife plaits or accordion plaits, a single blade only is actuated, while the other blade remains idle. Coupling means are provided for likewise actuating the second blade, whenever the machine is to be used for making box plaits. The invention comprises the various features of novelty more fully pointed out in the specification and appended claims.

lower cross bars 2. In the side plates, are hung a pair of superposed plaiting rollers 3 and 4:. Of these, the lower roller 3, is adapted to be heated either by electricity orby a suitable heating medium, introduced through its hollow shaft 5 said shaft beingl journaled in vertically movable boxes infiucnced by springs 7, so that the roller is adapted to bev takenalong by frictional contact with the fabric introduced between rollers 3, 4. The upper roller f1, is adapted to be intermittently rotated alternately in opposite directions in such a manner that the length of its stroke or arc of rotation, may be readily varied. The means for effecting this result are as follows:

In a bracket 8 mounted on one of the side plates 1, is journaled an operating shaft 9 which may be rotated either manually or by a pulley 10. Shaft 9 carries a crank disk 11 (Fig. 2) havinga radiallyT extend ing way 12 which adjustably receives a wrist pin 13 on one end of a pitman lil, the other end 'of which is by pin 15, connected to a. horizontally reciprocable rack 16, guided in ways 17. rThisl rack engages a toothed wheel or pinion 18 loose on the shaft 19 of upper roller 4t. To wheel 18 is pivoted alpawl. 20 (Fig. 11) engaging a ratchet wheel 21 fast on shaft 19. Thus the backward stroke of rack 16 will by wheel 18, pawl 2O and ratchet wheel 2l, turn roller 4 forward in the direction of the arrow a (Fig. 4f) the length of the backward stroke of the rack and consequently of the forward stroke of the roller being adjustable by means of lwrist pin 13 along radial way 12. Pin 15 likewise engages the upper forked end of a two arm lever 22, the lower forked end of which is by pin 23, link 24 and pin 25, adjustably connected to the lower forked end of a lever 2G, which turns on shaft 19 and carries a pawl 27 (Fig. 2). Lever 22 is adjustably mounted in its bearing, in such a manner that the relative length of its arms may be changed so that the length of its strokes may be correspond ingly adjusted. To this effect, the fulcrum 28 of lever 22 is embraced by a yoke 29 to which it is held by a set screw 30 (Fig. 10). Pivot 28 engages a slot 31 of lever and is fitted in a. guide way 32 of side plate 1. Thus by adjusting pivot 28 up or down, the stroke of lever 22 may be changed. Pawl 27 engages a ratchet wheel 33, the teeth of which are opposed to those of wheel 21, and

which is likewise fast on shaft 19. Thus by means of pitman 14, lever 22, link 24, lever 26, pawl 27, and ratchet wheel 33, roller 4 will be rotated backward or in the direction of the arrow b. By setting lever S22, or link 24, the length of the back stroke of the roller may be adjusted. In order to permit roller 4 to dwell for a time between its forward and backward turns, means are provided for throwing pawl 27 out of ratchet wheel 33 at the end of the forward turn of the roller. These means comprise a cam 34 mounted on shaft 9 and engaging a roller 35 of a bar 36 having at one end, a fork 37 that straddles shaft 9. The other end of bar 36 has an elongated eye 38 encompassing shaft 9, such end of the bar being rounded and adapted to operatively engage pawl 27. Upon the termination of the forward turn of roller 4, bar 36 will by the action of cam 34, swing pawl 27 away from ratchet .wheel 33 so as to arrest shaft 19 until, upon a half turn of shaft 9, cam 34 will be so positioned that bar 36 may be retracted by a spring 39, and pawl 27 will thus be thrown into rengagement with ratchet wheel 33. Thus the desired intermittent partial rotation of roller 4 and consequently of roller 3, will be accomplished.

Back of rollers 3 and 4 there are mounted a pair of superposed reciprocable knives or blades 40, 41 that converge with their free ends toward the pass between th'e rollers, while the reinforced backs of the blades are `furnished with laterally extending gudgeons 42, that engage guide ways 43 of side -plates l. For forming knife plaits and accordion plaits, only one of the blades, say the upper blade 40, requires to be reciprocated, while for box plaits, both bla-des must be alternately reciprocated. Means are therefore provided for either actuating the -upper blade alone, or for operating the same in conjunction with the lower blade.

The means for operating the upper blade are as follows: Back of blades 40, 41 there is mounted, a fixed table 44 carrying a pair of racks 45 one of which is shown in Fig. 5. These racks are engaged by pinions 46 fast on a transverse shaft 47 and held to the racks by guides 48. Shaft 47 is arranged in parallelism with rollers 3, 4 and substantially opposite to the roller pass, it ,being adapted to reciprocate to and fro across the table, so as to alternately approach or recede from said pass. For effecting this movement, disk 11 carries a cam 49 that engages a roller 50 mounted von one end of a lever 51, which is guided by means of a plunger 52 movable within a housing 53. The other end of lever 51 is at 54 connected to an oscillable arm 55, pivoted at 56, and engaging with its lower forked end, one of the protruding ends of shaft 47. Thus upon operating shaft 9, shaft 47 -will, by cam 49,

a pusher having upper and lower notches 61, so as to engage either the back of upper blade 40 or of lower blade 41. As thus far described the position of guide arm 58 is assumed to be such that upon an advance of shaft 47, pushers 6() will engage the back y of upper blade 40 only, so as to project the same toward the roller pass, while upon a recession of the shaft, blade 40 will be correspondingly -retracted by springs 62 engaging its gudgeons 42.

As has already been stated, means are provided, for so setting the machine, that in place of reciprocating the upper blade alone, both blades may be alternately reciprocated. These means are as follows:

To each side plate 1 is pivoted at 63, an elbow lever 64, influenced by a spring 65. The upper member of this lever is slotted as at 66 for the reception of a pin 67 extending from an arm 68 secured to upper blade 40. To the lower member of lever 64 is pivoted at 69, a latch 70 which, when brought into engagement with a support 71 will tilt the upper member of lever 64 downward (Fig. 4) and lock the lever in this position. The lower blade 41, is similar to the upper blade adapted to be retracted by a spring 72, and is furnished at each end with an arm 73, said arms underlying arms 68 of upper blade 40. One of the arms 73 carries a spring influenced :finger 74, adapted to engage a tripper 75 pivoted at 76, und infiuenced by a spring 77. Tripper 75 is provided with a pin 78 adapted to engage latch 70. The two juxtaposed arms 68 and 73 of bla-des 40 and 41 are connected to each other by a pivoted link 79 carrying a pin 80, that is interposed between the two Shanks of a doubled spring blade 81 secured to pusher 60. To one of the cross heads 57, there is pivoted at 82 (Fig. 6), a 'tappet or coupling,l member 83, adapted to engage a stop 84 protruding from guide arm 58. This guide arm is pivoted to a post 85, extending inwardly from lower arm of elbow lever 64.

When both of the blades 40 and 41 are to be alternately reoiprocated, it is merely necessary to swing tainpet '83'rupward and bring the same into c., `gemeint with the stop 84 of arm 58. Assuming shaft 47 to travel toward rollers 3, 4 and pusher 60 to be in engagement with upper blade 40, the latter will be advanced toward the rollers. Upon a receding motion of shaft 47, tappet 83 will carry arm 58 with it,

and'k the latterwill in turn, cause elbow lever 64. to be so swung on its fulcrum 63 that its upper' arm is lowered and that latch 70 will be raised into engagement with support 71, whereby lever 64k will be locked in position. During this movement, upper blade 40 being liberated from the receding pusher, will likewise recede owing to the action of its springs 62. Byv means .of this movement, link 79, will be tilted in such a manner that its pin 80 (which had previously borne against the lower side of the upper shank of spring 81) will bear against the upper side of the lower shank of spring 81 thereby tilting pusher 60 downward. When now shaft 4.7 is again advanced the pusher will engage the back of lower blade 41 andy cause the same to be projected toward the roller pass. The neXt receding movement of shaft 4:7 will cause finger 74 by tripper 75 to dislodge latch from support 71 whereby elbow lever 64: will be unlocked andwill under the influence of its spring 65 be so turned on its fulcrum G3 that its upper arm will be raised. Thus by means of pin 67 the free end of upper blade 40 will be slightly tilted downward. (This tilting movement of the upper blade is desirable for the purpose of bringing its operative edge into a kcommon horizontal' plane with the operative edge of the lower blade, i. e. into the approximate plane of the roller pass while such upper blade is advanced toward the rollers.) While shaft 47 recedes as described, lower blade 41 being liberated from pusher 60, will likewise be receded by its spring 72, and this movement of the blade, will cause link 79 to be so righted that itspin 80 will come into rengagement withthe upper-'shank of spring 81. In this way, the pusher will be again thrown upward, to engage and advancev uy per blade 4:0, during the next advance o shaft 47, which completes the cycle of operations.

In front of rollers 3, et there is mounted between plates l, a delivery table 86, along which the strip of fabric 87 is fed after being` plaited. Across this table, there is shown to extend a curved foot 88, carried by pivoted arms 89, and either held down upon the fabric by its own weight, or oscil- -lated off `and onto the fabric by suitable means (not shown). This foot which is cause part of such fabric j to be' doubled, and be folded over blade 40 which is being advanced while the rollers dwell. The blade will enter fold 90 and push the same toward and into the narrowest portion of the roller pass, where the fold becomes fixed by heat and pressure.

For making accordion plaits (Fig. 13) the machine is so adjusted that the forward and backward strokes of the rollers are alike, the blade entering fold 91 as described with reference to the knife plaits.

For making box plaits (Fig. 14) the back feed Should be about twice as long as the forward feed. The first backward and for ward stroke will form a lower fold 92 which is engaged by upper blade /1-0, and the next backward and forward stroke will form an upper fold 93 which is engaged by lower blade 41.

It will be seen that with all operations the foldsfare formed by the action of the rollers themselves, the blades having for their function more particularly to so place they fabric asy to be subjected to a. maximum roller pressure. The formation of the folds is therefore effected without unduly strainj ing the fabric, which would be the case were the latter forced around the operative edge of the blade. In this way, delicate fabrics may be operated upon, and the folding operations may take place in rapid order, without tearing or in other way injuriously affecting the fabric.
