From the drawing, and in particular from FIGS. 1, 1a and 2, it can be seen that the device has a shaft 1 which is as deep as the cigarettes are long are. In particular, the inside of the shaft is divided into individual shafts 1a, 1b and 1o. Own these shafts Partition walls 2, which between each other a gap equal to the size of the diameter of a cigarette form, which is why the partitions become thicker in the upward direction in cross-section and gradually downward decrease.

The partition walls are preferably limited in their downward course in a predetermined manner so that between their lower end and the bottom of the individual Bottom openings 3 of the shafts 1a, 1b and 1c spacing remain. These distances are for the middle partitions less and, as FIG. 1 shows in connection with the shaft 1c, the furthest from the middle Partition wall · »distant partition walls at the largest. As already in German patent no (patent application

A support 4a, 4b runs on each plate 3a, 3b and 3c and 4c, each of which in turn is at a higher level than the previous one (in the direction of advance of the Transfer organ, as will be described later).

These conditions are held by a cross member 5, which is actuated by one in the manner described in more detail below Rod 6 is moved.

On its rear side, the shaft 1 has a slot known per se which is so high that a support is inserted into it can be, whereas the shafts on the front have a corresponding counter slot, the is so high that a layer of cigarettes can be brought out above the plate 3a (3b, 3c) of the bottom mouth. In fact, the pads 4a, 4b, 4c, when entering through the corresponding rear slots, slide the cigarette layer from the shaft through the counter slots out. The supports 4a, 4b and 4c preferably have imprints (see Pig. 2) in the form of a circular bow, the is smaller than a semicircle, and the bottom mouths 3 have a width corresponding to each of the sum of the diameters of the cigarettes lying next to one another, which is due to the absence of additional strength dimensions, as they are

Once the ejector 64 has been pushed forward to perform the ejection operation, it must be brought back into the locked position by the pin 63. This is done by a lever 66 that is articulated around the pivot point 67 and is connected to the ejector 64 via the tabs 66a, in such a way that the Lever is only pulled forward when the ejector is triggered. The lever 66 also carries a loose roller 68, which with the profile part of the cam wheel 55 in contact stands. The latter has a deep gradation, which at.

In this bushing, the rod element 92 is non-rotatably connected to the holder 1o4 with the mentioned longitudinal axis coinciding with it. For this purpose, a sleeve 92a with an upper set of ports is mounted on the rod 92, which ends in a roller 92b which is displaceable in a longitudinal groove 1o4a of the sleeve holder 1o4. A rotatable part of thee sleeve 92a (which, as already mentioned, is fixedly connected to the rod 92) has at the location at which the push rod is hinged 91a, a pin 92b provided at the opposite ends of each of a loose roller 92c which runs in a groove formed in the stationary parts 1o8 of the housing 83. In this way, the straightness of the axial movement is ensured at the same time as a rotation of the rod 92.

It is evident that a rotation of the shaft 62 and consequently of the wheel 96 has a pendulum rotational movement in the holder 104 to the pole, which movement is transmitted to the rod-shaped element 92 so that it performs an axial reciprocating movement and a pendulum rotational movement .
