To all wkom it may concern.

Be 1t known that I, OSCAR SANDBERG, a subject of the Emperor of Russia and citizen of Finland, residing at Siidertelje, in the county of Stockholm and Kingdom of Sweden, have invented new and useful Improvementsin'Machines for Manufacturing Mouthpieces for Cigarette-Casings, of which the following is a specification.

This invention relates to machines for manufacture of mouthpieces for cigarette casings or cigarette tubes. One ObJGCt of this lnvention is to provide a machine suited for a rather high producing capacity,

so that the number of pieces completed in the time unitqwill considerably exceed those manufactured by hitherto known machines. Another object of this invention is to reduce the waste of the paper when manufacturing 7 the blanks for the mouthpieces. A further I manufacture the mouthpieces as hitherto known from a continuous paper strip the width of which equals the length of the completed mouthpiece, which strip I cut off in two different courses, so that the-cuts are alternatelv square and oblique. The forward end of every alternate cut ofl? piece consequently will be square, and these pieces I then give a rearward motion in relation to finally I force the tapered inner end of the rolled mouthpiece paper strip slightly rearwardly into the casing thus procuring at this end of the mouthpiece a small space where 'thetobacco, when introduced in the.

mentioned, I

casing, can enter the mouthpiece proper so far till it gets stopped up by the impressed paper end.

the upper roller 3 canbe slightly moved up and down relatively to the lower roll 2. Spiral springs 8, stretched between the journals 5 and the prongs 9 in'support- 6 render the upand down motion of the roller 3 elastic, so that the pressure from the upper roller 3 can be kept practically constant for varying thicknesses in the paper strip 1. The lower roller 2 has on its circumference two separate rough'parts 10 and llof difl'ei ent length and spaced by smooth parts 12, 13 for purposes which will be explained hereinafter.

In front of the feeding mechanism 2, 3 there is arranged a pair of scissors or knives 14 positioned" such, that they cut the paper strips 1 at right angle-with reference to the length direction of the strip, and which scissors or knives are put in action in any known manner, asfor instance by means of a cam disk 14.

At a suitable distance from the knives 14 there is located another pair of scissors or knives15, positionedin-an oblique direction relatively to the length of the paper strip 1 and actuated from a camdisk 15*. Between the two pairs of scissors 14, 15 there is a n 'up-and clownmovable bridge or table 17 (Fig. 9) actuated from an eccentric 20 on the shaft 19 which shaft is caused to revolve by means of a helical gear 4, a transmission shaft 18 and a bevel gear 18; The eccentric 20 operates the one arm 21 of a double lever, pivotable on a fu'lcrum 21 in the support 22, the rear arm 23 of which.

tion turned QOFdegreesabOut thesaid turning axis. As shown in Figs; 26, 27 and 28,

t the bridge 25 is of rectangular formation the longitudinal edges of which are provided with guides 90 secured to the bridge by means of screws 91. The bridge 25 is causedto turn by means of a ratchet device 36, 37 actuating a pivot 26 projecting from the one end of the bridge and journaled in a support 27. Said pivot 26 is indirectly operated from the ratchet device 36, 37 by means of a toothed gear 38, 38, the pinion 38 of which is positively revolved by the ratchet pawl 36 which operates the ratchet wheel 37 that is umnovably united with the pinion 38. The ratchet pawl-36 is carried by alink suspended rod 3G, the opposite end'of which is attached to a lever 39 pivotable about a fulcrum 39 on the frame38. A spring 40 actuating the link 40 of the rod- 36 tends to press the lever 39 against a cam disk 41 on the shaft 18 which cam disk transmits the revolving of shaft 18 on to the lever 39,-rod'36, ratchet device 36, 37, tootli'edgear 38 38 andbridge 25. To regulate the length of the movements of the rod 36 and consequently the movements of the ratchet mechanism and the bridge 25, the rod 36 is slidably connected with the lever 39 in a slot 42 therein.

The turning about of the bridge 25 is I checked by means of a pawl 34, actuated from a lever 30 and cooperating with a disk 28 keyed on the pivot. 26 of the'bridge 25. Said disk is provided with two diametrically opposed apertures 29 by which the pawl34, during the revolving of the pivot 26 with-the disk 28, alternately can be engaged and thereby prevent any further revolving of the disk and the journal 26 with bridge 25, until the pawl 34 isremoved from its engagement with the aperture 29. This removing of the pawl'34 is e-ffectedby means of a cam disk 33 on the shaft 19, provided with a projection 35 which cooperates with a roller 32 on the lever 30 in such a Way, that the roller 32 through the'projection 35 is pushed o'u'tward'thereby cau's'ingthe lever 30 to swing to the left hand (Fig. 10) removing the pawl 34 from the aperture 29; Aspring 31 keeps the lever 30 with pawl 34 against the plain surface portion of the disk 28, so that the pawl 34 always is prepared to immediately move into the apertures 29, as the one or the other of these two apertures has arrived in front of the pawl 34 during the revolving of the shaft 26. The'apertures 29 are so positioned with reference to the bridge 25 that the checking of same by means of the pawl 34 will always occur when the bridge occupies one or the other ofits two horizontal positions as illustrated in Figs. 1 and 2.

On eachof the horizontal sides of the bridge 25 there are feeding implements, one upper implement 43 and one lower implemeat 44', both pivotally mounted in a sup port 45 such, sotha't they can be revolved in a plane passing throughthe axis of the cigarette casing producing machine, not lllustrated 1n the drawlngs as not belonging continuous paper strip 1. These implements are each provided with. a concentrically 'curved working surface and are operated with a uniform revolvingmovement such, that, when their working surfaces pass along the respective sides of the bridge 25, they move in opposite directions'with; reference to the bridge, viz. the upper implement 43 in the same direction as the feeding direction of the continuous paper strip 1 and the lower implement 44 in the reverse direction -means of a toothed wheel 56 from the driving shaft 52 of the machine; -The Wheel 56 is provided with teeth *merely on a portion of its circumference, so that the pinions 56 on the two rolling needles shafts revolve only, when this portion of the wheel 56 is engaging with them, but remain at rest'during the other portion of the" turn of the shaft 52. The rolling'needlesa're each surrounded by a sleeve 48 (Figs. 19, 20) which do not take part in the revolving of :the needles and which serve to take up in themselves the rolled mouth'pieces I, 79, which mouth pieces are subsequently ushed-outward off the rolling needles 47, 4 a by means of tube shaped pushers 49 each surrounding needle 47, or47- within the respective sleeve 48 (Figs. 16-18). The pushers 49 are provided each with a prong 5O movable along its sleeve 48 in a slot 51' to guide the reciprocating motion of the pusher 49. The

'pushers 49 are reciprocally operated from the driving shaft 52 by means of a drum 53 provided with a curved slot 54- in which moves a finger .55 projecting from the support'55 for the-pushers 49, which=finger 55 during the revolving of the drum 53 follows the slot 54 and thus moves the support 55 with the pushers-49-forward and rearward with referenceto the needles 47,47. 4

In front of thesleeves 48 there is a wheel 57 journaled in bearings 58. This wheel has its entire circumference provided with axial corrugations 58 for the reception and transportation of the c1garettecasmgs80,

which are supplied to the wheel 57 from the to this invention.-aThe wheel 57 is madeto revolve intermittently from the shaft 52 by means of a ratchet mechanism of which merely the ratchet wheel 57 isillustrated in the drawing, and by which mechanism the wheel'57 is revolved a distance corresponding to the double T pitch of the corrugations 58.x I)

'mouth piece 79 therein. are arranged on a support 62 from whlch In frontof each rolling needle 47, 47 is provided a plunger 59 reciprocatin to and from the respective needles in the irection of thein'length by means of which, the

cigarette casings 80, guided in the corrugations 58, are moved ahead toward the corresponding sleeve 48. The sleeves 48 may be somewhat tapered at the end, so that the cigarette casing 80, which is manufactured of very thin paper, canbe expanded a little at the end to facilitate the insertion of the The plungcrs .59

descends afinger- 63 movable in a curved slot 61 on the circumference of a drum '60 keyed 011 the driving shaft 52, whereby the plungers receive their reciprocating movements when the shaft 52 revolves. Inthe support 62 there are further mounted two rods 64 parallel to the plungers 59 and spaced apart so far that, when pushing the plungers. ahead toward the wheel 57, each plunger 59 as well as each rod 64 moves along one of the corrugations 58 of the wheel 57, which, during this period of the working'of-the machine is kept at. rest as itis not "actuated this moment from the ratchet mechanism 57 The rods 64 are tapered or rounded at their ends and serve to push the inner end of the mouthpiece paper spiral somewhat rearward in order to produce the small space for receiving a portion of the tobacco also in the'mouth piece proper as mentioned before. For this reason the rods 64 must be applied on that side of the plungers'59 to which the upper portion of the wheel 57 moves during its. revolving, so' that the rods do not actuate the mouthpieces before these have been inserted into their cigarette casings 80. To hold the imouthpieces 79 firmly during. this inward pushing of their ends there isprovided a clamping device 7 0 (Figs. 12, '13) guided up and down in a stanchion 71 having a lug 72 the wheel corrugation 58 (dotted lines'in Fig. 12). The clamping device is oper-- ated by double lever 75 pivoted about, a

' fulcrum 76 and actuated by a cam disk 77 on the shaft 4. V

The machine is drivenby means of a belt on a pulley 65 on the shaft 52 beyond'which is provided a loose pulley 66'as usual for stopping the working of the machine. The machine operates as follows: The paper strip 1 is fed along between the rollers 2 and 3 by means of the longer rough.

portion 10 of roller 7 2 till the foremost (square) edge of the strip has arrived just below the feeding implement 43 above the horizontally positioned bridge 25 as. illus- .tratedfiin'Fig.v 21 aswell as, in View I' of'" Fig; 25: In exactly thismoment theentirewrouglrportion 10 of :roller; 2. has re- .leased the paper'strip l and. the for-ward piece 79.
