The compression of the tobacco in the chamber 6 is as shown in FIGS. 2 and 4, as follows: Pigur 2 shows the chamber 6 open for the introduction of a tobacco filling The fixed abutment ram 28 is pushed aside and the operating handle 16 is pulled outward so far that the stuffing rod is withdrawn from the chamber 6 so that only the spoon-shaped part is in the chamber 6. From Pigur 4 it can be seen that the lever 10 is rotatable in a plate 30 by the pin 32 and the inner end 34 of the lever 10 is rotatably connected to the toggle rod 36 by pin 38. Dae other end of the joints 38 Tange, in turn, is rotatably mounted on the verechieblichen base plate 8 by a pin 40 which reaches through the Schiit "40 into the plate 30 and bottom plate in atm. 8 The bottom plate 8 is more movable with deir. Stamp 26 connected, as Pigur 2 shows.

It can be seen from FIGS. 2 and 4 that during the pressing process 4 different stamps against the fixed stamp 28, to compress the tobacco mass by pressing the handle 12 and lever 10 takes place. The stamp 26 can be seen in a position for the tobacco pick-up in Pigur 2 and 4j in broken lines Lines (Pigur 4) you can see the position of the handle 12 and the lever 10 at the moment when the punch 26 sioh. in press division is located.

As soon as the tobacco is compressed in this way in the chamber 6, specifically in the channel-shaped space 20, one pushes with the shoulder 44 at the inner end of the stuffing rod 18, the tobacco from the Chamber 6 to the outside and through the hollow mouthpiece 14 and ron here into the cigarette tube by pushing the handle into the housing.

As long as the tobacco is pushed into the sleeve 13, the pawl 22, which is rotatably attached to the housing 4, holds " by means of pin 46 - the sleeve is fixed to the mouthpiece · The pin 46 is guided in a link slot 48 shown as a curved slot. The mode of operation of the pawl 22 in relation to the MuHfettick 14 is determined by the cam or the like on the gearshift rod 24, which cooperates with the pawl piece 50 on the resilient pawl 22.

A preferred form of a shift rod 24 is shown in FIG. 5 here the rod has a U-shaped cross-section with webs 52 and 54.

For the purpose of better understanding, FIG. 5 also shows the stuffing rod 18 parallel to it and its spoon part 20, which is also is attached to the handle 16, shown with.

The upper edges of the webs 52 and 54 above. Flatter 56 and 58 that with the above-mentioned pawl piece 50 of the retaining pawl come to the intervention. When the pin 46 of the pawl 22 in his shifted to the left position (A in Figure 6) of the arcuate Slot 48 is standing, the pawl piece 50 engages

109853/1090

into the recess 56 when the pin 46 is displaced in the row in position B (FIG. 7), the pawl piece lies down 50 when the shift rod 24 is moved to the cam surface 58.

Each of these upper cards with the buttons 56 and 58 also includes notches or recesses 60 at the end of the rod ar "other end opposite handle 26 · As a result, when handle 26 fully bac ^ gezoere ^{a 1} is in the position shown in Fiimr 1 the pawl in either one or the other recess 60 jump in and is thus raised so far from the mouthpiece 14 that a cigarette tube can now be slipped onto the mouthpiece it can be seen from Figures 3, 6, 7 and 8, where a spring 65 is shown on a bent tab 67 of the pawl.

According to Figure 5 haber. the profile strips 53 and 54 of the further recesses 62 and 64 approximately in the middle, whereby the length of the Button 56 is larger than that of button 58. As can easily be seen, this means that when button 50 the pawl on button 52 (i.e., when the pin 46 is in the position at A) the pawl on the mouthpiece 14 reads for a longer advance of the shift rod 24 (and the stuffing rod 18) than when the pin 46 is in position B is located. So if you want to make cigarettes with filter inserts, that's what you do. Pivot pin 46 in position B

1098E3 / 1090

and in position A if the sleeve is used continuously open

because open-ended tubes require a longer tobacco filling length than normal-length tubes, but with a filter insert.

To use the device, you pull the handle 16 back completely, thereby the pawl 2? from the mouthpiece as a result lifted off the recess 60, then you put a sleeve on the mouthpiece. Now you pivot the lever 10 so that the tobacco chamber 6 is opened. Then one sets the pivot pin 46 in either position A or position B, as the case may be whether you want to manufacture full or filter cigarettes. You put a fair amount of tobacco on it into the chamber 6; pivots the lever 10 so that the tobacco is compressed between the punches 26 and 28 and pushes the handle 16 inwardly into the housing. This achieves I. the introduction of tobacco loading by dae Mundatüok H into the cigarette tube and II. Apply the latch f 22 to the sleeve pushed onto the mouthpiece, which is thus held in place until it is completely plugged. As soon as the stuffing process ends, the pawl 22 enters the detent 62 (or 64) and thus comes out of contact with the Sleeve and allows the finished cigarette to torn the mouthpiece advance of the shoulder 44 of the stuffing rod is deported.
