As is well known, cigar fillers are inserted in a pressing mold in which they remain a certain time before they receive further treatment, by being enclosed in a wrapper. In the manufacture of cigars by mechanical means the problem to be solved is to transfer a filler issuing from the rolling device into the pressing mold by mechanical means. In this operation it is important that the fillers should be exactly in the prescribed position when they are introduced into the known trough of the pressure mold.

According to the present invention, an intermediate support, adapted to the shape of the fillers and formed for instance of two flexible clamping jaws, is provided and is reciprocated between the receiving and the delivery positions, and is fixed in the end positions by adjusting devices, for instance stops.

In this manner it is possible with simple constructional means for the filler to be caused to pass directly from the rolling device and to arrive in the correct position in the intermediate support, and to be delivered by this intermediate support into the trough of the pressure mold in an accurately determined position.

The intermediate support is preferably, arranged on a sliding member or the like so as to be frictionally displaceable in longitudinal direction, and at both ends of the travel stops are provided in such manner that when the intermediate support comes into contact with the stops it is held in the correct position.

Accordingly, without the use of any special control member, the intermediate support is adjusted in its two end positions by a slight displacement on its sliding member.

The intermediate support formed of flexible clamping jaws or the like forms a channel open at the top and bottom and, at the delivery posi- 40 tion, a suitably shaped plunger is adapted to enter the channel from above and to thrust the filler downwards into the opened pressure mold. Thus it is rendered possible for a plunger to pass the filler held by the intermediate support, directly into the trough of the pressure mold, because the channel formed by the intermediate support, in which channel the filler lies, is located in an exactly fixed position in relation to the plunger and the trough.

The intermediate support is preferably mounted on two parallel bars attached to a sliding member or the like so as to be displaceable in a longitudinal direction, each of these bars entering grooves formed on one side by guide surfaces of the intermediate support and on the other side by leaf springs attached to the intermediate support. Further, in the case of longitudinally divided intermediate supports drawn together by springs, one guide bar is mounted on the sliding member so as to be capable of outward movement, and is displaced by a cam or the like in such manner that, in the receiving position, the two parts of the intermediate support are opened, and actuated fingers prevent the filler from fallingthrough the opened intermediate support. 10

If the sliding member on which the intermediate support is mounted is arranged on an endless chain reciprocated over sprocket wheels in the direction of movement of the sliding member, the supporting fingers which prevent the filler from 15 falling through the opened pair of clamping jaws of the intermediate support, may be simply attached to the same chain in such manner that when the chain is passed over one sprocket wheel they are removed from the path of the inter- 2O mediate support when the support, while carrying the filler, moves to the delivery position.

One form of construction of the invention is illustrated in the annexed drawings, in which:-

Fig. 1 is a front view. 25

Fig. 2 is a plan.

Fig. 3 is a part of Fig. 1 on an enlarged scale.

Fig. 4 is a plan of Fig. 3.

Fig. 6 shows the part of the apparatus illus- 30',

trated in Fig. 3, in another operative position.

Fig. 7 shows a cross section along the line 1--1 of Fig. 5.

The jaws l which serve for receiving the filler are shaped in such manner that they leave between them a vertical free space I which is open at the two opposite sides and conforms to the shape of the filler. Each of the jaws l is attached by screws 2 to intermediate supports 3 which are shaped in the manner shown in Fig. 7, 40 With their U-shaped parts, the intermediate supports 3 embrace fiat bars 4, 4', and guide surfaces 3 of the intermediate support 3 are pressed by leaf springs 5, which are attached by the bolts 6 to the intermediate supports 3 against 45,,

the corresponding surfaces of the slide bars 4, 4' so thatthe intermediate supports 3 are mounted as sliding members and are longitudinally displaceable on the bars 4', i. The slide bar i is attached to the sliding member 1 which is mount- 50 ed so as to be horizontally displaceable in the slideway 3. The slideway 8 is attached to the table-like projection 9 of the machine frame 9. The slide bar 4 is mounted on a bell crank lever Ill, which at H is pivotally mounted on the slid- 55 ing member I and is subjected to the action of a spring l2. On the free arm of the bell crank lever it is mounted the roller G3, which co-operates with a cam track M which is fixed to the slideway 8 by screws. On the bell-crank lever It a screw i5 is provided which comes into 0011- 7 tact with a stop It of the sliding member T. The sliding member 7 is fixed at l to a chain H which is passed over the guide wheels I8, I9, 26. The guide wheel 29 is mounted on the axle 2i mounted on a bracket 9 on which axle a spur wheel 22 is mounted. The latter co-operates with a rack 33 which is held on the bracket 9 so as to be capable of longitudinal displacement. At one end of the rack a link 24 is pivotally connected at 23, this .link being articulated on the other side at 25 to the lever 25; The lever 25 is pivoted at 26 in the machine frame 9. A roller 2i mounted on this lever engages in the cam groove 28 of a cam disc 28 which is mounted on the driving shaft 29 of the apparatus.

To the 'chain ii are attached fingers for the fillers in the form of metal plates 38.

The mode of operation of the apparatus is as follows:

When the sliding member 7 moves into the position shown in Fig. 2, the roller l3 comes into contact with the cam member M, whereby the lever is is'swivelled so that'the jaws i (Fig. 6) are transferred to the open position for receiving the filler W delivered by the rolling apron 3|. The movement of the chain I! is such that the jaws l are brought into contact with a stop 32 1 provided on the table .9, and are retained in a definite position by the said stop. The filler which falls down from the rolling table 3i thus falls between the open jaws l, and the metal plates (fingers) 3B prevent the filler W from falling through. Now the sliding member 1 is moved by the chain l i into the delivery position marked a. At this position is located the pressure mold 33, which is so arranged that an empty chamber is disposed under a vertically displaceable plunge-r 34 (the plunger is indicated in Fig. 2 by dotted lines). In the movement of the slide to the delivery position x; the cam 84 liberates the lever IE so that owing to the tension of the spring [2 it assumes the position shown in Fig. 3, where the screw i5 rests against the stop. Thus the filler is clamped between the jaws I. By the movement of the chain member over the sprocket wheel IS, the metal plates 30 are moved out of the range of the jaws l. The chain movement in this case also is so arranged that before the slide 1 arrives in the end position, the jaws strike against a stop 35 associated with the guide of the plunger 3% and by this stop are held in the correct position in relation to the plunger 34, or the corresponding pressure chamber. As soon as the plunger 35 has moved downwards and has thereby thrust the filler W from the pair of jaws time the pressure chamber, the plunger returns, whereupon the sliding member also returns to its initial position and the process is repeated, in that the jaws I again come into contact with the stop 32, and the filler formed on the rolling table 3 l is moved from the rolling table 3| into the open pair of jaws.

In the above form of construction simple stops 32 or 35 are provided which retain the pair of jaws l, I in the correct position. It is self-. evident that instead of stops, bolts or the like may be provided which engage in suitable recesses in the jaws, or their support.
