; '3 Claims. (crass- 5) ting device (not shown). At the bottom ofthe chamber 2 a number of partitions i is provided, ten in the present case, constituted by upright plates 5. Preferably, the heightof the said plates varies in such manner, that the plate located nearest to the opening in the bottomof the magazinel is highest and the -heightsof the plates 7 then successively decreases outwards, as shown in Fig. 1. In. the form of execution shown as an example inthe drawing each plate 5 at its lower part is provided withjlateral projections; 6. The, said projections, which together constitute the bottom of the partitions 4, are located'at some distance from each other, so that tobacco, which possibly falls out from the cigarettes, may leave the partitions through the slots located between the said projections. Plates 5 are swingably mounted by means of pins 7 journaled in walls 8 at the front and rear sides of the magazine. A pin 9 extends downwards from each plate and engages a notch 10 providedin a rod 12, which is slidable in stationaryguides 11. A link 13 is pivotally connected to 'the' said rod 12 and engages by means of a pin 14 a groove 15, which is provided in an arm 1'7 swingable on a pin 16. The said arm .17 is rapidlyoscillated for instance by a crank pin 18, having a die 17 which is slidable in a groove in the opposite side of the arm 16. The said pin is provided on a shaft 20, which is rotated by the driving shaft of the machine by means of a suitable motion transmitting device (notshown) comprising for instance a belt pul- 1ey 21 Link 13 is connected at its outer end to a hand-lever 23by means of a link 22; The said hand-lever 23 may be locked in difierent positions by a catch 26, which is held by a spring 24 in engagement with a fixed toothed segment .25. By shifting the hand-lever the position of the pin 14 in the groove 15 is altered. A fixed rod 27 is provided near the bottom of the partitions, which permits the lowermost row of cigarettes at the bottom of the partitions to be ejected but retains the next superposed" rows of cigarettes. The lowermost row. of cigarettes may be ejected in the ordinary manner by means of a piston (not shown) divided into fingers.

Through the link and crank connection described above and shown in the drawing the rod 12 is moved rapidly forwards and backwards and causes the walls 5 to oscillate rapidly. Owing to the said movement of the plates 5 the partitions will be well filled with cigarettes descending into the same from the store located above the partitions. 1

In packaging cigarettes and otherstarf-shaped articles the cigarettes generally are. placed into amagazine, at the bottom of which they are distributed into rows in. vertical partitions from pistonor the like andinsets of sucha number as isto. be introducedinto a box orthe like. for the packaging of the same. This invention relates to a'device in magazinesof the said type for causing the cigarettes by subjecting the same toa shaking operation to passdownwards in the said partitions in a reliable manner. The movement of the walls of the partitions necessary for the said purpose is so adapted,that it is greatest at the'top part of the partition walls and decreases downwards towards the bottom of the same. 'As to magazines of the type inwhich the cigarettes'move laterally into a space above the said partitions, the walls of the, partitions may beso arranged, thatthe heights of the same decrease from the wall locate d nearest to the magazine and successively outwards, so'that the top ends of the walls and the uppermost cigarettes in the partitions constitute a slanting plane, along which the cigarettes slide downwards above the partitions in a reliable manner and are substantially uniformly distributed above the partitions. This arrangement of the partition walls may be used also in the case that the partition walls are fixed. If the'said arrangement is used in, combination with swinging walls the advantage is gained, that, owing to the fact that the actuation, to which the cigarettes are subjected by the swinging partition walls and which causes the same to move, is greatest nearest to the maga-, zine and decreases outwards with the reduced height of the walls, the uniformity of the distribution of the cigarettes above the partitions will be still more increased. I

Aform of execution of the invention is illustrated in the accompanying drawing. Fig. 1 shows in a front View, partially in section a magazine'which is provided at its bottom with partitions arranged in accordance with this invention. Fig. 2 is a top view of the partitions and the actuating mechanism of the partition walls. The drawing illustrates the magazine and its parts diagrammatically. I 1 is the magazine containing cigarettes. For causing the cigarettes to move downwards from the magazine into a lower, slanting chamber 2 a roller 3 is'journaled at the bottom of the magazine, which is rotated by the driving shaft of the machine in the direction indicated by the arrow by means of a suitable motion transmit- As perceived from Fig. 1, the top ends of the walls 5 and the uppermost cigarettes in the partitions constitute, owing to the reduced heights of the plates 5 from the bottom opening of the magazine outwards, an outwardly slanting plane, on which the cigarettes will slide. The movement of the cigarettes outwards in the chamber 2 is hereby considerably facilitated. In addition hereto the higher plates owing to their greater amplitude exert a greater moving action on the cigerally of the magazine and communicating with the bottom part of the same, swingable partition walls provided in the said chamber and dividing the cigarettes into substantially upright rows, said walls having the swinging point so located, that the greatest eifective stroke of the walls is at their top ends, the said ends being located in a surface slanting outwardly from the magazine, and a mechanism imparting to the walls a swinging movement.

arettes, which action of the plates decreases suc so that there always is a store of-cigarettes above,

each partition. By altering the position of the pin 14 in the groove 15 by shifting the hand-lever 23, the stroke of the rod 12 and the angle through which the plates swung will be varied, so that the swinging motion of the plates and the shaking of the cigarettes may be adjusted to the most suitable or, if necessary, be interrupted.

As already stated above the arrangement of partition walls having reduced heights may be applied with advantage also to stationary partition walls.

The invention may, evidently, be modified in some respects without exceeding the limits of the same.

I claim: '1. In a machine for packaging cigarettes and other staff-shaped articles the combination of a magazine for the articles, a chamber located lat- 2. In a machine for packaging cigarettes and other staff-shaped articles the combination of a magazine for the articles, a chamber located laterally of the magazine and communicating with the bottom part of the same and partition Walls provided in the said chamber and dividing the cigarettes into substantially upright rows, the top ends of the said walls being located in a surface slanting outwardly from the magazine.

3. In a machine for packaging cigarettes and other staiT-shaped articles the combination of a magazine for the articles, swingably journaled partition walls, which divide the cigarettes into substantially upright rows from which sets of cigarettes are discharged, the swinging point of the said walls being located at the discharge point of the upright rows, and lateral projections on the partition walls, located at the said swinging points and forming two by two. bottom walls in the partitions.
