Little cigars and also certain types of cigars generally are manufactured in a shape substantially square in cross-section. Among the reasons herefor may be mentioned that the little cigars etc. require smaller boxes or other packings. originally are cylindrical, the said square shape, the little cigars hitherto have been disposed in a great number, for instance 1000 little cigars, in

superposed rows in a box and then subjected to a.

pressure during a comparatively long period. Practical experiments however have proved that little cigars subjected separately or in a small number of rows for instance one or two rows to a repeated pressure or a continuous pressure during a comparatively short period assume the said square cross-sectional shape which they then maintain, if immediately introduced into the box etc. The present invention is based upon this experience.

According to one form of execution of the invention the little cigars are transferred fromsocalled galleys in which they are located in a plurality of superposed rows of for instance 100' little cigars, onto a conveyer band, from which groups of little cigars of, for instance, five pieces are pushed by slides or the like into movable receptacles, two rows for instance of little cigars being placed one upon the other in each receptacle. The said receptacles are moved beyond a number of pistons which one after the other subject each set of little cigars to a repeated pressure The pressed little cigars are then pushed by aslide or the like from the last pressure piston into the boxes respectively or other packings which are mounted in receptacles moved beyond the said pressure receptacles.

According to a further form of execution of the pressure and packing machine the pressure pistons accompany the pressure receptacles during a part of their path and keep the sets of little cigars subjected to a continuous pressure during a longer period.

A further modification consists in placing th little cigars in receptacles provided with pressure members which at one point of the path of the movable receptacles are forced downwards into heir pressing position and are locked in the same and at another point of the said path are disengaged so that the little cigars may be introduced into the boxes etc.

Some forms of execution ofthe pressure and packing machine are shown as examples in the accompanying drawings. Fig. l is a front view of the left part of the machine arranged in ac- For imparting to the little cigars which.

The little cigars I are placed in superposed rows in frames or galleys'2 and 3, two frames being provided in the machine in question, Figs. 1, 4 and 5. A conveyor-band, beltor the like passing

round rollers

4 and 5 is provided in front or. the galley 2. A slide 8 movable in guides l pushes the lowermost row of little cigars in the galley onto the top partof the band 6. The saidband 6 is driven continuously in the direction indicated by the arrow, Fig. 5. A stationary pocket 9 open toward the galley 2 is provided at the right part of the band 6, in which pocket the set of little cigars carried by the band and moved forward by the same isstopped. In the present case the said pocket is adapted to contain a set of five little cigars or a somewhat greater number located in a compact row and laterally of each other. The pocket is open at its sides so that a slide 10 movcigars from the galley 3 to the said band. At

the left part of the band I6 a stationary pocket H3 is provided, Fig. 6, which may contain a set of five little cigars or a somewhat greater number. The sets of little cigars are transferred 'one after theother by a slide l9 to the receptacles The conveyer band I6 is located at such a higher level than the conveyer band 6, that the set of little cigars transmitted from the band I6 to a receptacle II is placed on the set transmitted from the band 6 into the same receptacle asperceived from Fig. 4. The members stated above are driven by the main shaft 20 of the machine and the motion transmission means which will now be described. The said shaft 26 rotates by means of a bevel gear 2| 22, a shaft 23, which by means of a chain 24 and sprocket wheels 25 and 26 rotates the shaft 21 carrying the roller M. A gearing 28, 29 transmits the rotary motion to .a shaft 30, carrying the roller 5. Owing to the fact that the slide 8 transmits from the galley 2 to the band 6 a row of little cigars, which is a multiple of the set of little cigars which is transmitted by the slide ID from the band 6 into a receptacle H, the slide 8 may be caused to operate only when the slide 10 transmits the last set of the next preceding row transmitted to'the band 6. In order to impart to the slide 8 such a movement a sprocket wheel 3|, Fig. '1, is fixed to the shaft 26, which by means of a chain 32 rotates a sprocket wheel 34 rotatably mounted on a shaft 33. A sprocket wheel 35 is connected to the sprocket wheel 36 and rotates by means of a chain 36 a sprocket wheel 61 freely mounted on the shaft 26. As perceived from Fig. 7, the stated chain and sprocket gearing is so adapted, that number of revolutions of the sprocket wheel 31 is a fractional part of the number of revolutions of the sprocket wheel SI and the shaft 26. The ratio of gearing is adapted to ,the numbers of transmissions, which .are to be effected by the slides 8 and ill separately during a certain period. A cam disc 38 is connected to sprocket wheel 31, which at the proper moment of time permits a spring 39 to move a lever arm 4| swingably mounted on a shaft 40 toward the left, Fig. 7. The said lever arm 4| may be fork shaped and engages a pin provided on the slide 8 and in this manner imparts to the slide the necessary motion.

Motion is imparted to the slide ID by a fork shaped lever arm 42, Fig. 8, which is swingably mounted on the shaft 46 and by .a spring 43 is forced against a cam disc 46 on the shaft 20.

The slides l1 and is are actuated by a driving mechanism of the same construction as the driving mechanism of the slides 8 and I6 Just described.

After a set of little cigars delivered by the galley 2 and a set delivered by the galley 3 have been introduced into the receptacles the chain is advanced in the direction indicated by the arrow and through a distance equal to the distance between the centre lines of the receptacles. The said intermittent motion is imparted to the chain by the roller l3 mounted on a shaft 45, which is providedwith a toothed wheel 46, Fig. 3, engage provided with two sets of little cigars they are successively placed under a number of pressure pistons, in the present case four

pistons

49, 50, 5|

and 52, Figs. 2 and 3. The said pressure pistons are mounted on a crosshead 53, common to the same and fixed to a slide or rodv 55 which is movable upwards and downwards'in guides 54 provided in the frame of the machine. The slide together with the pressure pistons is moved downwards at the proper moment by a two-armed lever 51, 58, which is swingably mounted on a pin and the fork-shaped arm 51 of which engages a die 59 provided on the slide 55. The fork-shaped end of a second arm 58 is engaged by a'nut 60 on a rod 6| and aring 63 slidable on the rod 6| and acted upon by .a spring 62. The said spring 62 is supported by a nut 64 by means of which the tension of the spring may be controlled. The rod 6|, which is fork-shaped and engages the shaft 20 and is guided by the same, has a roller 65 which engages a lateral groove provided in a driving disc 66 on the shaft 20. As the rod 6| is moved upwards by the said grooved disc 66, it forces by means of the spring 62 the

pressure pistons

49, 50, 5| and 52 downwards against the little cigars located in the four receptacles The pressure of the pistons on the little cigars may be controlled by adapting the starting tension of the spring 62 by means of the nut 54. As the pressure pistons have been moved upwards the chain is advanced one step so that the little cigars in each receptacle finally have been subjected four times to the pressure of the pressure pistons i. e. to the pressure executed first by the piston 49 then by the piston 50, again by the piston 5i and finally by the piston 52. The little cigars thus pressed have a square crosssectional shape.

After the little cigars have been pressed by th last piston 52 they are ejected from the receptacle by a slide 61, Figs. 3 and 9, which through a mouth piece 68 transmits the little cigars into .a box 69, or a packing of other type and located in receptacles provided in a chain 10. As the mechanism for bringing the boxes into the said receptacles is not comprised by the present invention, they are not shown nor described. The chain 10 passes'round discs 1| and 12, Fig. 2. Disc 1| is fixed on the shaft 48 and is rotated intermittently, so that the receptacles 10 provided with empty boxes are successively placed in front of the mouth-plece 68. After the boxes have been charged with cigarettes, they are closed and ejected from the chain in any suitable manner.

A pin in the slide 61, provided with a. die 1|, Figs. 3 and 9, is embraced by the fork-shaped end of an arm 12, which is fixed on a shaft 13 journaled in the frame or the machine, see also Fig. 3. A second arm 14 is fixed to the said shaft 18, to which arm a rod 16 is Jointed, which embraces the shaft 20 .and is guided by the same. The said rod is provided with a roller 11, which is acted upon by a cam disc 16 on the shaft 20. The cam disc 16 permits a spring (not shown) to move the Before the little cigars are subjected to the action of the first pressure piston 49, the ends of the little "cigars of each group preferably are caused to flush with each other. Fig. 10 shows a mechanism for this purpose. Two elbow-shaped arms I8, 19 and 89, 8| are swingably mounted on.

stationary pins

82 and 83 and the arms I9 and BI turned inwards engage one another for instance by means of a notch 84 in the arm I9 and a projection 85 on the arm 8| so that the swinging motion of the elbow-shaped arm 89, SI is transmitted to the arm I8, I9. The ends of the arms I8 and B0 are provided with ribs 85 and 81' projecting inwards and adapted to enter the receptacle placed under the pressure piston 49 and by pressure on the ends of the little cigars to bring the little cigars into a flush position, as shown in Fig. 10. The elbow-shaped

arm

80, 8| has an arm 88, to which is jointed a link 89, which by means of its fork-shaped end is guided by the shaft 20. A cam disc 99 is fixed on the shaft 20 and a roller 9I on the link 89 is forced by a spring (not shown) against the said disc 90. The disc 90 is so shaped, that it permits the said spring to swing the arms I8 and 89 inwards for the purpose stated above, the arms I8 and 88 being then swung outwards by the cam disc 99.

Through the pressure to which the little cigars in the receptacles I I are repeatedly subjected the little cigars assume the square shape, which is necessary for the introducing oi the same into the boxes. Besides, the great advantage is gained that the little cigars are divided into groups, which after the performance of the pressing operation are ready to be introduced into the box etc.

By the provision of pressure molds and pressure pistons of suitable shape another cross-sectional shape than the square shape may evidently be imparted to the little cigars.

In the form of execution of the invention shown in Figs. 11 and 12, pressure pistons 93 co-operate with receptacles or molds 92, which pistons are movable longitudinally in the links 94 of a chain passing round discs or

rollers

95 and 98. The said chain is driven by the shaft 99 which carries the driving disc or roller I00 of the receptacle chain. Motion is transmitted to the disc 96 by means of

toothed wheels

97 and 98 having the same diameter (the said toothed wheels are shown only by dotted lines). The

discs

95, 96 and I99 have the same diameter and the distances between the centre lines of the receptacles 92 and the centre lines of the pressure pistons 93 are equal, so that during the motion of the receptacles and the pistons in the directions, indicated by the arrows the receptacles and the pistons coincide and the pistons may descend in the respective receptacles. During the pressing operation the links 94 of the chain are guided by rollers IIlI, which are journaled on lateral projections IGI on the links and enter into groove-shaped, stationary guides I82 and I93 provided one at each side of the path of the receptacle chain. On the rod I94 of each pressure piston 93 two rollers I95 are journaled, which engage groove-shaped stationary guides I05 and I ill while the pressure pistons are in their operative position. The left part of the guides I96 and Iil'I is funnel-shaped, so that the entrance of the rollers I05 into the guides is facilitated and besides the pressure pistons respectively are forced downwards into the receptacles 95 and subject the two sets of little cigars I68 located in the receptacle to a pressure. The said little cigars may have been introduced into the receptacles in the same manner as in the machine shown in Figs. 1-10 inclusive. The first, left part of the guides I96 and H11 is parallel to the path of the partition'chain, so that the pressure pistons remain in their lowered operative position. The top part of the chain is sustained by a bar I09 or the like extending longitudinally of the chain. The lower part of the chain is sustained by a similar bar I99 The distance between the right part of the guides I86 and I 91 and the path of the pressure receptacles increases gradually at a, so that the pressure pistons are moved upwards and their pressure on the little "cigars is reduced or ceases. The guides I86 and I91 may then be parallel to the path of the receptacles, so that the pistons remain in their position in the receptacles and serve as guides for the pressed little cigars while pushed out of the receptacles and into the boxes etc., which may be efiected in the same manner as stated above. The receptacle chains may be moved continuously, at least at a comparatively slight rate, because the slides introducing the little cigars into the compressor receptacles and the slides removing the same may be moved at a velocity adapted thereto. The output of the machine may hereby be considerably increased.

As perceived from Fig. 11, the little cigars are subjected to pressure from the pistons 93, while the receptacles are moved through a distance substantially equal to the length of four receptacles. Through the pressing thus described the square cross-sectional shape is imparted tothe little cigars. By rendering the guides I06 and I81 for instance wave shaped the pistons 93 will be lowered and raised a plurality of times and thus subject the little cigars to a repeated pressure.

In the form of the pressing machine illustrated in Figs. 13, 14, 15 and 16 each of the pressure receptacles H0 is provided with a pressure member III which extends into the receptacle and is guided by the same and by two pins II2 fixed to the bottom wall of the receptacle and provided with a head. A two-armed locking member or pawl I I3 is pivoted at II4 to the pressure member III and is provided in its ends with semicircular lateral recesses II5. In the side of the said recesses II5 teeth H6, adapted to engage corresponding teeth III on top end of the pins II2, are provided. Springs II8, one slid on each pin H2 and bearing with its one end against the bottom wall of the receptacle III! and with its other end against the pressure member I I I force the latter normally against the heads of the pins IIZ. ber tends to swing the pawl I I3, I I5 into engagement with the teeth I II of the pins I I2, so that as the pressure member III is forced downward'in the manner stated below, after the pressure receptacle has been charged with little cigars, the pressure member III may be locked in any desired operative position by the pawl H3, H5 engaging the teeth III of the pins H2, Fig. 16. The pressure receptacles are connected with each other and constitute an endless chain, which passes round the rollers or discs I20 and I2I. The said discs are rotated step by step by the main shaft of the machine by a motion transmitting device, not shown.

During the travelling of the said chain in the direction indicated by the arrows, Fig. 13, the receptacles charged with cigarettes, are placed, one after the other, below a fork-shaped piston #22, which at the suitable moment is lowered and forces the pressure member, III downwards into A spring II9, fixed to the pressure memthe receptacle, the pressure member beingthen locked in its lower operative position by the pawl I I3, I I5 in the manner stated above.

The piston I22 is movable in a guide I23 and to the top end of the piston rod is connected the fork-shaped end of a two-armed lever I24, which is pivoted to a bracket I25. The downward movement is imparted to the piston I22, against the action of a spring I26, by a cam disc I21 on a shaft I28 which is rotated by the main shaft of the machine by means of a motion transmitting device, not shown.

The little cigars placed in'the receptacle III] are compressed by the lowered pressure member or piston I22 and are held in the compressed condition by the locked pressure member while the I movement of the receptacles is continued.

The receptacles with the compressed little cigars finally arrive to a station, where the pawl H3, H5 is disengaged and the pressure of the pressure piston I22 on the little cigars is reduced.

I28 is a piston which is movable in a bracket I30 and may be lowered by a cam disc I 3i rotated by the main shaft, and'a two armed lever I32 against the tension of a spring I33. The said arm I32 is fork-shaped and connected to the piston I29. As a. receptacle is located under the piston I29, the piston is lowered in the stated manner and acting upon the head of the pin H4 lowers the pressure member III through 'a short distance, so that the pressure between the teeth I iii of the pawl I'I3, ion the teeth II! of the pins H2 is reduced or ceases. Atsubsiantially the same time a'pin I34 fixed'in the pawl H3, H5 has struck a roller I35, journaled on a two-armed lever I36, which is swingably mounted on the bracket I30 and acted upon by a'spring I31. The

normal position of the lever arm is fixed by 2. preferably adjustable abutment (screw) I38.

As the pin I34 strikes the roller I35 the lever arm I36 is swung through a slight angle, so that after the reducing of the pressure between the teeth I it and II! has been efifected in the stated manner, the pawl I I3, I I5 is disengaged and the pressure member released. The compressed little cigars may then be pushed out from the receptacle guided by the pressure member and introduced into the box in a. manner analogousto the manner described above with reference to Figs. 3 and 9.

In order that the compressing period may be as long as possible the station, 'atwhich the receptacles are charged'with little cigars, which may be effected analogous to the manner stated above, is located between the pistons I29 and I22,-

so that the little cigars are subjected to pressure while the receptacles pass round the left disc or roller I20 and from this roller to the right roller I2I and round the roller last mentioned to the piston I29. The comparatively long period, during which the little cigars thus are subjected to pressure insures the desired squarev crosssectional shape of the little cigars and besides I the little cigars are subjected to a drying process during the said passage. The top and lower parts of the receptacle chain are sustained during the said travelling by guide bars I39 and I4!) respectively.

' The degree'to which the little cigars are compressedmay be controlled by the change of cam disc I21. Through the provision of two or more piston devices of for instance the same construction as the piston device I 22 and the parts belonging to the same along the path of the receptacle chain the little cigars by suitably adapting similar articles a cross-sectional shape different from the ordinary circular cross-sectional shape, the combination of means forming receptacles to contain one or'more rows of cigars, means for moving said receptacles in an endless path, pressure members one for each receptacle, means provided at a point of'the said path for forcing each pressure member against the cigars contained by its receptacle, each receptacle having a spring-mechanism tending to move its pressure member outward from the receptacle, means for locking each pressure member in operative position, and means at a second point of the said path for disengaging the said locking means to reduce the pressure of the pressure member on the cigar.

2. A machine as claimed in claim 1 characterized by the locking means for the pressure mem ber comprising one or more toothedpins fixed in walls of the receptacles, a spring-actuated toothed arm, swingably mounted on the pressure 3i member, and an abutment located in the path of the toothed arm to disengage the same.

3. In a machine for converting loose cigars into covered bundles, the combination of a mem-.
