IVAR OSKAR ENGELBREKT SANIDBERG, OF STOGKHOLM, SYVEIDEN CIGAR MACHINE Application filed January 30, 1931, Serial No. 512,440, and in Sweden February 6, 1930.

The invention has for its object to simplify the construction'of the cigar-rolling machines at present in use.

With this and other objects in view the invention consists in certain constructions, improvements and combinations as will be hereinafter fully described and then specifically pointed out in the claims hereunto appended. The invention is diagrammatically illustrated on the accompanying drawings on which Figs. 1, 2 and 3 are top plan view, side elevation and end elevation, respectively, of my machine.

Figs. 4 and 5 are side elevation and end elevation respectively, on an enlarged scale of a swinging arm carrying the rollers adapted to rotate the bunch, with the gears serving to rotate the rollers and a device for controlling the operation of a needle to clamp the wrapper against the bunch.

Fig. 6 is a plan view of apart of the swing ing arm and parts of the needle controlling device. 7

Figs. 7 and 8 are end elevation and plan view, respectively, of two cutters with their supporting levers and parts of the rollers.

Fig. 9 is aview in end elevation of two supporting levers for the rollers and stops 7 to swing said levers.

Fig. 10 is a detail view necessary to the complete understanding of the mode of operation of the cutters. The machine as illustrated comprises a table 1 which may be supported at the proper height above the floor by any well known means not shown. A shaft 2 driven from any suitable source of power not shown is mounted below the table 1 and carries a cam cylinder 3 having a circumferential groove 4 and a cam groove 5 formed in one end surface of the cylinder 3. A roller 6 engages the groove 4 and is pivotally mounted at one end of a lever 7 carried by a vertical shaft 8 journalled in a bearing 9 at the top of the table 1 andcarrying a lever 10 at its upper end. i

A gear segment 11 is formed integral with the lever 10 and is in mesh with agear 12 secured to the lower end of a sleeve 13 surrounding a hollow shaft 14 extending through a bearing 15 at the top of the table 1. Mountedat the upper end of the sleeve 13 are an arm 16, a gear 17 and another arm 18 provided with a passage 19 communicatin g with the interior of the hollow shaft 14, through an aperture formedin the wall of the shaft 14. At its upper end the shaft 14 is closed by means of a threaded plug 20. I The opposite end of the lever 18 carries a depending sleeve 21 surrounding a tube 22 closed at its upper end by a threaded plug 25. The interior of the tube 22 communicates with the passage 19 through an aperture formed in the upper portion of the wall of the tube 22. At its lower end, the tube 22 carries a plate 23 supporting the wrapper carrier 24 in such a manner as to permit an easy removal thereof. The wrapper carrier 24 comprises a hollow member the interior of i which communicates with the interior of the tube 22. The lower surface of the wrapper carrier 24 adapted to receive the wrapper is perforated whereby the wrapper may be held against the lower surface of the wrapper carrier by means of suction due'to the partial vacuum existing in the tube 14 and transmitted through the passage 19 and the tube 22 to the interior of the wrapper carrier 24.

The arm 18 is apertured between its ends T to receive a bolt 26 the upper and lower ends of whichproject from the arm 18 and support levers 27 and 28, respectively. A roller 30 is pivotally mounted on the lower lever 27 by means of a pin 29 while the upper lever 28 by means of a link 31 is connected to a lever 32 secured to the upper end of the tube 22. The pivots between the link 31 and the levers 28 and 32 are shown at 33.

A roller 34 engages the cam groove 5 and is pivotally mounted on a pin 50 mounted at one end of a bell- crank lever 35, 36 swingably mounted at one end of a shaft 42 jour-- nalled in a bearing 37 secured to the lower surface of the table 1. v

38 represents a pin by means of which the upper end of the bell- crank lever 35, 36 is pivoted to a projection 39 from the lower surface of a support 40 for the cutting edge 41 (Fig. 1) corresponding to the desired contour of the Wrapper. Pivotally mounted at the opposite end of the shaft 42 is a link 43 pivoted by means of a pin 44 to another projection 45 from the lower surface of the support 40. Between its ends the shaft 42 supports two horizontal levers 45 which at their opposite ends carry a pin 46. Pivotally mounted on 's'ai di pinf46 is a lever 47 ext-ending upwardshnd "parallelly with the arm 36 and the link 43 and pivoted to a projection"'49' from the front side oflthe'support by means of a pin 48. I

The support 40 is perforated at its-upper surface whereby a blank to be out to form a Wrapper when-laid down onto the support 40z'is held thereagainst by means of suction Tpro'duced by'the." partial vaeuum existing 'in thefinteriorVof the support 40. Thehlank onfthe' cut'tingfedge *41 is ear to a wrapper 2 oft-he desired-shapeby means of two cutters described in detail later onand adapted to be mavedever the cutting edge 41. The Wrapper "thus obtained is supplied to the 'wra'pperzss ert srwhen the support 140 un- 40 53cafryingacamfplate '55lattache'd to the please by; means of bolts" 56, and additionth rellin "mechanism comprisin four .rolle'rs h8 'rotated I 'in the same d'ireetion and "serving to 'rotate'the' bun oh introduce d therebetweenQThretar movementof'therro ll- "rs 58' is earned" from thearm 16 by "means ofa gg'ear' flo' ivetall 'inounted thereonand in niesh with"? a" stationaryfgear 17.

The 1owerrollers 58 are in "turn rotated byme'anstr -gears 7 7 "inserted between the gears65and gears 66 mounted on thelowerro1lers58. The rollers sea-re io'urnalle'd in bell-"crank levers 67 and ,68Ja'n'd the ends'of the two upper rollers 58 project'into arms' 69 secured tobars 78- carried by the plate 53 toform "stati'onary'p'ivots ff'or the-lever'sf 67 and 68 whereb 'the'latter :cjan'be; "swung into thefpos'ition' as sh wn in Fi ejfor the urpo e of're'ceiving a'jbun'ch 'maneuvering'th finished cigar. The rollers 58 are opened and closed in the bunch receiving and cigar delivering positions, respectively, by means of stationary stops 7 O and 71, respectively. Of these stops the stop 70 operates in the bunch receiving position 70 by actuating a projection 7 2 from the lever 67 While the stop 71 operates in the cigar delivering position by actin' g up'on a corresponding projection 73 'frointhe lever 68. The'levers 67 and 68 intermesh as shown at 75 '-75 aIrd a'sairesult itis suficient to operate one only of the levers 67 and 68 in each of --said two positions.

As may be seen from Figs. 7 and 8 two "swingabledevers aremounted -on the bars 80 78beyond the rollers: 58. Said levers 80: are interconnected by means of springs 81 and carry two" rotary cutters'i8'3 and '84 of conical shape. During the swinging movement of the 'arm'16 said cutters are moved overthe blankplacedon the cutting edge 41 to cut s aid hlankto the desired shape the cutters 83 and84beingpressed against the blank by means of the springs' 81 and cutter 83 cooperating with the outer portion and cutter i 84 withthe inner portion of thecutting'edge '41. :The reason why'the cutters 83 and 84 are conical in'shape appearsfrom Fig. 10 in which '86 'denotesthe generatrix of. one of the cutters While 41 denotes the cutting edge on anj enlarged scale. The blank is cut at where the generatri'x 86 is 'incontact with the'cut'ting edge-41. v

The 'rm 16 carries a device to operate the needle '90 to clamp the'end of the wrapper s against the'bunc'h inthe beginning of the wrapping "operation. Said device comprises a swingablelever 92'suppo'rted by projections -91 depending from the lower surface of the arm 16. Secured to the;lower end of said los '1ever'92' is a" spring 93wvh'ich in turn carries a lever94-the outer end of which forms a loop '95 whichsurrounding a' pin "96 and situated between a'inember'97 conical at one end and an annul r'member 98 both secured-to theano pin' 96. The rear end of the pirf'SJG'eXte-nds through an aperture 991at' one end of a supby'prejssed down to clamp the wrapper against the bunch. After the bunch has been rota't'ed about one andIa half revolutions the needle 90 'W'illbe; returned: to its initial posit on' by means of the sprin -93 when the levereal'eavesth sto 101.

The operation of'the machine is as follows: -In;t'he, poslt onot-the swinging arm 16 and f-the' olling mechanism as'flmstrated. in- Fi "rinwhich position the lower rollers 58 occupy tionary gear 17. During this movement the -arm16 gradually reaches a position in which the cam plate 55 attached thereto strikes against the roller 30 which normally by means of a spring is held in the position shown in full lines in which lever 28 is pressed against a stop 111 mounted on the arm 18 to hold the support 40 parallelly with the wrapper carrier 24. In the continued swingingmovement of the arm 16 the lever 27 and as a result also the wrapper carrier 24 will be turned whereby the latter reaches the posititon represented by the broken line at whattime the arm 16 occupies the position represented by the broken line 121. Approximately in this position the wrapping of the wrapper at the lower surface of the wrapper carrier 24; onto the bunch situated between the rollers 58 and rotated thereby begins upon the needle 90 (Fig. 4) having entered a downwardly open recess at the lower surface of the wrapper carrier 24 and been pressed down to clamp the inner end of the wrapper against the corresponding end of the bunch. The arm 16 continues its swinging movement and the rotating bunch removes the wrapper from the wrapper carrier 24 the latter being swung in such a manner about its pivot that the wrapper is wound smoothly onto the bunch. After the arm 16 has been swung through an angle of about from the initial position the lower rollers 58 are opened in the manner illustrated in Fig. 9 in that the projection 7 3 strikes against the stop 71 whereby the finished cigar situated between the rollers 58 is delivered onto any suitable conveyor not shown.

During the swinging movement of the arm 16 between the bunch receiving and cigar delivering positions the cutters 83, 84 cut the blank placed on the cutting edge 41 in the lower position thereof to form a wrapper for the next cigar said wrapper being subsequently supplied to the wrapper 24 when the cutting edge 41 is raised under control of the groove 5. Should the operator not find time to stretch the blank before the cutters 83, 8 1 reach the cutting edge this may be done afterwards upon the cutters having passed the cutting edge 41 because said outters are operative to cut a blank also when the arm 16 after having discharged the cigar is returned to its initial position clockwise to receive another bunch. Accordingly the cutting edge 41 preferably is not raised towards the wrapper carrier 2411mm after the cutters 83, 84 during the return movement of the arm 16 have passed the cutting edge 11.

By replacing the cam plate 55 by similar cam plates of different shape bunches'diifering in shape may be wrapped in the machine. If desired the rotary speed of the bunch when the wrapper is wound thereon may be varied to secure a smooth wrapping of the wrapper onto the bunch by turning the gear 17 about its axis by suitable means not shown, preferably under control of a replaceable cam cylinder. Obviously the arm 16 upon having delivered the wrapped bunch may continue to rotate in the same direction and thus revolve in one direction only, stopping for a moment in two positions during each revolution about 180 apart to receive a fresh bunch and deliver a wrapped bunch. If desired the machine when operating in this manner may be arranged to wrap a bunch also during the latter part of the revolution, that is when moving from the cigar delivering position into the bunch receiving position.

The machine may be adapted for use in wrapping both halves of a tobacco-leaf simply by providing the means for rotatingthe bunch about its axis with a reversing gearing "not shown, preferably by substituting such a gearing for the bevel gears 61, 62whereby the bunch during the movement from the bunch receiving position into the cigar delivering position may be rotated in either direction about its aXis to enable the wrapping of both halves of a tobacco-leaf in one andthe samewrapper during the movement between said two positions and movable back-and forth between the path of said cutters and said wrapper carrier to transfer the wrapper cut to said wrapper carrier.
