((1. 221-118) This invention relates to a device for distributing portions of pulverous, granular or other material, for instance tobacco, sugar, coifee or tablets, which portions may be packed immedi-;

ately or delivered to a weighing'process, for instance before they are packed.

' It is a main object of the invention to provide simple, eflicient and rapidly operating means for delivery of material from a receptacle without subjecting the material to rough treatment,

thus avoiding grinding or crushing action upon same.

In the drawings:

Fig. l is an elevational front view of an embodiment of a distributing machine according to the invention;

Fig. 2 is an elevational sectional view taken on the line n n of Fig. 1;

Figs. 3 and 4 illustrate two steps of the distributing process;

Fig. 5 shows a part of the machine, and

Fig. 6 is a cross sectional view taken on the line VI-VI of Fi 5.

It is assumed, by way of example, that the machine shown in the drawings is adapted for distributing portions of tobacco mass which is supplied to a receptacle 2 which has a joiting bottom plate 3. At its bottom the receptacle 2 has four openings 50, and in their lower position four measuring chambers 4 form each a downwardly directed extension of said openings. The measuring chambers l are secured to a beam it which is secured at its ends to two rods II which are displaceable up and down in the frame ii. The rods II are each by means of a link it and av lever it moved up and down by a cam disc It, secured to a rotating driving shaft l2, so that the measuring chambers 4 move periodically between the end positions shown in Figs. 2 and 3. A piston 5 is movable up and down in each measuring chamber 4. The pistons I are mounted each on a rod l1, and said rods are jointly securedto a cross bar II, which is displaceabiy mounted on the rods II. The cross bar I. is operated by a pair of links it and levers secured to a shaft I, which is rotatably iournalled in the machine frame 5|. Another lever 2i, secured to the shaft I, is operated by a cam disc 22 which is secured to the shaft i2. The rods II are adjustable relative to the rods II in such manner that the pistons 5 can be adjusted ver-' ed on the rods H, viz. by means of two pinions 42' (Figs. 5 and 6) on a shaft 24; said pinions mesh with toothed parts ll of the rods II. For

adjustment, the shaft 24 is turned, so that the abutments 23 are moved simultaneously up and down on the rods I I, whereafter the abutments are clamped to the rods II by means of set screws 42.

In operation, the measuring chambers 4 and the pistons 5 are first elevated into the position shown in Fig. 3 with their upper rims at a'level with a plate 6, whereby each measuring chamber 4 separates from the contents of the receptacle 2 the tobacco portion slipped down into it from the receptacle 2. Thereby an excess of tobacco (see Fig. 3) is separated, which has to be removed, so as to obtain a portion of an exactly predetermined size. For that purpose a scrapingofl? plate I is movable to the left (Fig. 3) close over the upper rim of the measming chamber 4 and scrapes or! the excess, which is thereby again supplied to the tobacco mass in the receptacle 2. Immediately thereafter the piston l is elevated, whereat the measuring chamber remains in its height shown in Fig. 4, so that the tobacco portion is pushed out of same. Immediately thereafter the scraping-off plate 1 moves to the right (Fig. 4) so that the tobacco portion is displaced upon the plate 6 and slips'from the plate 6 down through the channel 8 into the funnel 9, from which it is supplied to the treatment, for instance manufacture of cigars.

For advancing and reversing the scraping-off plate I as mentioned there is provided a third 1 cam disc 29 mounted on the shaft l2 and operating a lever 28, which is secured to a rock shaft 21. Furthermore, two lever arms 28 are secured to the shaft 21, and their ends are secured to a rod 25 which is movable in guide slots 54. The plate I is secured to said rod 25.

In case material likely to be crushed is manipulated it is advisable to provide the plate I at its bottom end with a scraping-oil. brush or the like, or to replace it completely by such a brush.

I claim:

1. In a device for distributing portions of pulverous, granular, fibrous or other material, for instance tobacco, a. receptacle for the material to be distributed, a measuring chamber having an open top end and being movable ,up and down in said receptacle, 9. piston movable up and down within said chamber, a table, a scrapingofl' member, and means to first elevate said chamber to position its top end substantially at a level with said table, then to move said scraping-on therefrom to a receiver.
