8 Claims.

Myinvention relates to'improvements in apparatus for turning out decorative material, especially decorative material of Cellophane, in strip form, worked to give it the pleated and spiral appearance of the product shown and described in my PatentNo. 2,112,723, granted March 29,1938;

Anximportant object of this invention is to provide mechanism for twisting the Cellophane strip in the final stage after pleating; so designed that the capacity of the apparatus is enlarged and the speedof manufacture increased. Also waste is reduced and costs are decreased. Instead of Cellophane, paper maybeused.

Other objects and'advantages are set forth in the ensuing description taken with theiaccompanying drawings, which illustrate a preferred embodiment of the invention. But the disclosure is of course explanatory only; and changes in various details may be made without departing from the principles'of the invention or going'beyond the meaning'of the terms in which the appended claims are expressed.

On the drawings:

The apparatus mounts one or more reels 1 woundwith strips of' Cel-lophane or paper 2, and atleast one reel 3 bearing a coil of wire 4. The strips 2 receive the wire l'loetweenthem and are'fed by feed rolls 5 and'B tothetwister 'at tachment or mechanism 1; The 'wire 4 is retarded somewhat in relation to the strips -2-; and

when the combined strips with the wire forming a core emerge from the rolls they-are transversely pleated; In this condition the twister 1 revolves the strips about thecore; and gives to the finished product the form of spirals orconvolutions, as fully described in my aforesaid patent and inmy prior PatentNo. 2,157,583, granted May 9,4939. 1 a

I'hesupporting framework of the machine is shown part at 8. One or more members shown diagrammatically at 9 carry a motor 10,

framework 8.

- having a pulleyat one end' of itsarm'ature shaft to drive a larger pulleyll on'the end of a shaft [2, suitably mounted i a belt l 3f. Atits opposite end said shaft carries a gear- 1'4? toactuatea similar gear 14 meshing with a gear'l5"ontheshaft I6 of the lower pulley 5. The upper roll .5 turns, on a shaft or trunnions 16a and is rotated by friction from the lower roll 5' and the strips 2 passing between the tworolls. The. motor, belting and gearing for the pulleys and various cooperating parts are arranged in any suitable manner in the t The pressure of the upper roll 5 on. the lower is regulated by'springs l1, bearing on the trunnions orshaft' lBa ofthe upper rolls 5, or on the ends thereof. The springs are controlled by bolts or screws [8 in projections orposts t9 on the framework 8.1 Only the lower rolls appear in Figure 3, for the sake ofclearness.

;I 'he, rollst iarejlikewi'se" disposed one above the other; and the lower has a shaft 23 carryingage'ar 21 connected by a chain 22 to a gear 20 on the shaft of'the lower roll 5'. The rollers 6 are preferably halfthe diameter of the rolls 5, and are driven at twice the speed of'rotation, so thatthe peripheral speed of the rolls Bland 6 is, properly matched. The upper roll 6 is also rotated by Iriction and itspressure on the lower roll 6 is regulated by elements of the same kind as for the upper roller 5. Rolls 5 and 6 are of course located so that the strips pass them in astraight horizontal line. V Brackets ,24 secured to the framework support he shaft of the; lower reel .l, and brackets 26 arr th sha r t nm r he. upper reel 1. The brackets .24 also hear idle rolls 25 over which the strips 2 pass to the feed rolls 5.

The twister l comprisesa fixedplate 21erranged transversely of the framework, and fixed thereon; being firmly attached at its lower edge .to a cross angle-bar 28 on the framework. In thecnter of the plate .21 is an opening 29. Betwee'nithe plate 27 and the feed rolls .6 is a fixed annular gear or rack 30. The center of the openm 2.9 isirl line With the Ihiddleof the length of the fe'edrolls, and the gear 30 is concentric therewith. This gear-is held in place by a bent bar or" bracket" 3| connecting it to theplate 21 at" the (bottom, and by ahorizontal bracket 32 connecting itto'the'plate 2'! at the top; A space 'of some width separates the plate 21 from the gear-30;: Betweenthe gear '30 and the i plate '2! is a pulley ring 33 with a groove 34 in itscircumference.

n the framework, through" .Flanged rollers 35 on the plate 21 surrounding the opening 29 support the pulley ring 33, and are rotatably mounted by means of screws or bolts engaging the plate 21 and forming suitable journals onwhich the rollers are free to turn. The inside edge 36 of the ring 33 fits these rollers between the flange thereof; and thus the ring is rotatably secured on the position also concentric with the opening 29. The ring is of course larger than this opening.

Spanning the ring I gential to the opening 29 are angle bars 31, fixed at their ends upon raised seats 38 on the ring 33. Two shafts 39 are mounted at opposite point on the ring 33, by means of bearings 40 von this ring; and the outer extremities of the shafts 39, carry gears 4| which mesh with the gear 39. as the ring 33 turns,

33, in position to be tan face of the plate 21 in Y Hence the shafts 39 revolve with it and rotate about their own long axes as the gears roll along on the annular seats 38 terminate short of the inner edge of the ring 33, so that they clear the rollers 35 as the ring 33 revolves.

The shafts 39 also have bearing engagement with the outstandingflanges of the angle bars 31; and adjacent said flanges carry pinions 42. The flanges 0f the bars 31 which engage the seats 38 have slots or recesses 43 to enable the pinions to clear these bars. Also mounted in suitable bearing openings in the outstanding flanges of the bars 31 and extending across between them are spindles 44; one at each side of the spindle 39; and each of'these spindles carries at one end a fixed gear 45. The gears 45 mesh with the pinions 42 and are disposed in As illustrated in Figure 5, the gears and pinions are so arranged that one of the gears 45 is at one end of the spindle 44 carrying it, and the other gear 45 is atthe opposite end of the other spindle. Hence, as the pulley ring 33 revolves and its gears 4| roll on the fixed gear 36, the two spindles 44 will rotate in opposite directions. In Figure 2, for the sake of clearness, the top bearing 48 and top gear 4| are omitted; and the gears 4| and 45 are indicated in broken lines.

jRigid with the inner faces of the outstandin flanges of the angle bars 31 are two flat bars 46. These bars 46 extend through the opening '29 in theplate 21. djacent their extremities beyond the plate 21 each bar 46 carries a fixed transverse bar 41, which is flat and secured to the inner faces of the bar 46. The ends of the bars=41 project beyond the opposite edges of the flat bars 46; and to each outer end of the two bars 41 is fixed a short flat link 48 extending towards the plate 21. These links lie beyond the edges of the bars'46 and along same, and they support chain gears 49. One such gear is carried by each such link; and the gears 49 are matched by four similar gears 49, two on each spindle 44. Each gear on a link 48 will be connected by an endless chain 50 to the gear in line therewith on one of the spindles 44; and the four chains will all be parallel tothe bars 46' and to one another. The journals 54 for the gears 49 on the links 48 may be of any suitable type; and the links may be adjustably secured as by bolts and nuts to the bars 41 Between" the outer ends of the bars 46 is a cylindrical guide sleeve 5|. It begins adjacent the cross bars 41 and extends beyond the extremities of' thebars 46. On the outer, faces of the bars.

'46 at the ends are fixed cross bars 52 also extending beyond the opposite edges of the bars 46; and bridged at their extremities by connecting gear or rack 30. The" the same recesses 43.

bolts 53. By meansof nuts these bolts can be tightened to grip the guide sleeve 5| and hold it in place. The bars 46, bolts 53 and sleeve 5| constitute a single member or frame to receive the strip and wire leaving the rolls 5 and 6.

Spacing and reinforcing bars 55 may be placed between the angle bars 31 and the adjacent ends of the flat bars 46; all said bars having bearing openings for the shafts 39 and 44.

The pulley ring 33 is turned by a belt or cable 56 in the groove 34 and also engaging a rooved pulley 51. This pulley 51 is mounted on shaft other en'dofthe shaft of the motor I0. 7 The reel or spool'3 for the wire 4 is mounted to turn freely on a fixed spindle 64, which is fixed in an open frame 69. Keyed on the Spindle 64 and engaging one end of the reel 3 is a ring 65; and between this ring and a fixed collar 66 on the spindle 64 is a spiral spring 61 on the spindle. As the; spool turns, the ring 65 acts as a brake to retard the reel and the paying out of the wire 4 thereon. The frame 69 is mounted to rotate in a fixed yoke 68 secured on the framework 8. The frame 69 turns on trunnions 16 and 1|, the latter being hollow to enable the wire to pass through it. On this trunnion 1| is a pulley 12, which is operated by a cable 13 running also over a pulley 14. This pulley is mounted on another shaft 15 in bearings on the framework 8 and having a worm 15 at its other end to engage a wormwheel on the haft l2.

In practice the work strip 2. emerges from the rolls 6 with transverse pleats thereon, as indicated in Figure 1 at 16. Passing in between the bars 46, it is engaged by the chains 50 and pushed on through the sleeve 5| to be cutoff into the desired lengths as it emerges. Between the bars 46 the material is turned into spiral convoluted form as indicated at 11 and shown'fully in my patents aforesaid. The gears 49'rotate in such direction that the sections of the elements or chains 50 which engage the material impel it towards the sleeve. Thus the lower sections of the'chains 50 in Figure 2 run from right to left and the corresponding sections of the other two chains move in the same direction. or, by reference to Fi ure 5, the sections of the chains that are farthest from the edge of the opening 29always move in the same direction, which is away from the observer. Hence the required feeding' and'delivery effect is secured. \All this time the pulley ring 33 and the bars 46 are revolving about a line parallel to the bars 46 and passing through the center of the opening 29; and simultaneously with the feeding the material is twisted as desired.

The twister works well also with one strip 2 of Cellophane and a singlestrand of wire. 'At the start, the wire and the-Cellophane are simply pushed through between the rollers 5 and 6, and one end of the wire is bent orhooked. The operation then pushes the, stripmaterial which impels the wire onward. The wire being retarded by the brake 65, the strip is pushed along by the rolls and is transversely pleated as itleaves the rolls 6. A small box 18 may be mounted in the framework to contain an adhesive; The wire passes .over or through the sides of the box, in which is mounted awheel 19 that dips into the adhesive. As the wire passes it runs .between flanges on this wheel andis covered by the adhesive which makes, it holdto the striporstrips more firmly and give a more uniform product,

The rotation of the frame 69 and reel 3 ofisets it runs off the reel3. Two wires and one strip of Cellophane between them may be worked in the same way.

When paper is employed instead of Cellophane, the twister operations may be performed with two strips and one wire, one strip and one wire, or two wires with a strip between.
