and in Great Britain June 2, 1930 10 Claims. (01. 22M) This invention is for improvements in or relating to machinery for packing cigarettes, and refers more particularly to a cigarette hopper adapted to feed simultaneously two batches of cigarettes -to a machine designed to pack cigarettes in a double pocket carton of the type comprising two pockets united by a flap.

The present invention consists of a hopper for feeding cigarettes to a machine operable to pack cigarettes in a double pocket carton of the type referred to which comprises mechanism operable to feed simultaneously two side by side batches of cigarettes spaced apart laterally on to carton blanks moved by a conveyor at right angles to the direction of movement of the cigarettes, the

batches of cigarettes being delivered to points disposed at unequal distances from the feeding mechanism, so that each pair of batches of cigarettes is fed to a pair of successive blanks and the indi- 'vidual batches of each pair are disposed on opposite sides of the centre line of the conveyor.

The invention will be more particularly described with reference to the accompanying drawing, in which:

' Fig. 1 is a plan view of a cigarette feeding apparatus constructed according to the invention.

Fig. 2 is a section of Fig. 1 on line 22.

Fig. 3 is a fragmentary view of the machine bed shown in Fig. 1 with some of the parts removed.

Fig. 4 is a perspective view of a blank having one batch of cigarettes thereon.

Fig. 5 is a similar view of a blank having two batches of cigarettes thereon.

Referring to the drawing, a hopper orbox 1 is provided having two distinct sets of vane openings 3 and 4 separated by a spacing member, the space between the centre line of each set of vane openings being equal to the pitch of the pusher pieces 5 carried by a chain conveyor 6 operable to move carton blanks 7 through the packing machine.

The cigarettes are removed from the vane openings by a conveyor 8 of the kind described in the prior U. S. patent to Walter E. Molins, No.

1,618,214, granted February 22, 1927, having pusher pieces 8* and are carried across a plate 9 and a support 10 mounted above the machined bed 11.

The support is shaped so that the cigarettes of '10 for a distance equal to the length of a cigarette, as shown in Fig. 2. The movement is repeated and one batch of the leading pair of batches of cigarettes (i. e., the batch fed from the vane openings 3) is permitted to fall from the support lfl'leaving the other supported thereon.

' This method of moving the'batches is clearly shown in Fig. 3. The batch falls on to the carton blank onthe near side of the conveyor, thus producing a partly loaded blank as shown'in Fig. 4.

The conveyor 6, which is intermittently operated, moves on one stage and upon the delivery of the next pair of batches of cigarettes, one batch falls upon the near side of the conveyor on the next succeeding blank, whilst the other batch is delivered upon the far side of the conveyor, and on to the blank which has previously receiveda batch of cigarettes so that each blank receives its pair of batches in two distinct operations, and when loaded is as shown in Fig. 5.

The conveyor of the packing machine is intermittently moved so that the blanks come to rest .in line with the batches of cigarettes, and after the first blank has passed, each movement of the the others by a distance equal tothe width of the flap.

The cigarettes which are delivered from the vanes in comparatively loose formation are closed in to compact batches by tapered guides 13, whilst a top plate 14 prevents the cigarettes from rising up during this movement.

In order to ensure that the batches fall cleanly and without displacement on to the blank, two pressing plates 15 are provided which are carried on pivoted levers 16 and operated by ordinary cams (not shown) to move downwards at the instant the batches of cigarettes fall and press them into position on the blanks.

What we claim as our invention and desire to secure by Letters Patent is:-

1. In apparatus for feeding cigarettes to a double pocket carton adapted to receive two batches of cigarettes, the combination with means for moving a row of cartons through a predetermined path with the pockets of each carton aligned transversely of the row, and means for simultaneously feeding batches of cigarettes to each of two successive cartons in the row. 7

2. In apparatus for feeding cigarettes to a double pocket carton adaptedto receive two batches of cigarettes, the combination with means for moving a row of cartons through a predetermined path with the pockets of each carton simultaneously feeding a batch of cigarettes-to one pocket of a carton, and a batch of cigarettes to the oppositely positioned pocket of the succeeding carton.

3. In apparatus for feeding cigarettes to a double pocket carton adapted to receive two batches of cigarettes, the combination with an intermittently operated conveyor for moving two cartons with the pockets arranged transversely of the conveyor into two predetermined positions of rest in succession, of means for feeding each of two rows of cigarette batches transversely of the direction of movement of the conveyor and toward one of the positions of rest of the cartons, and means for constraining the leading batch of cigarettes in one of said rows to move across the near pocket of one of said cartons for delivery to the far pocket of the carton.

4.In apparatus for feeding cigarettes to a double pocket carton adapted to receive two batches of cigarettes, the'combination with an intermittently operated conveyor for moving a plurality of cartons with the pockets thereof arranged in two rows spaced laterally of the direction of movement of the conveyor into two predetermined positions of rest, means for feeding two rows of batches of cigarettes transversely of the direction of movement of the conveyor and delivering one batch in each row of batches to each of two pockets in the separate rows of pockets while the cartons occupy one of the said positions of rest.

5. In apparatus for feeding cigarettes to a double pocket carton adapted to receive 'two batches of cigarettes, the combination with an intermittently operated conveyor for moving "a plurality of cartons with the pockets thereof arranged in two rows spaced laterally of the direction of movement of the'conveyor into two predetermined positions of rest, means for feeding two rows of batches of cigarettes transversely of the direction of movement of the conveyor and delivering one batch in each row of batches to each of two pockets in the separate rows of pockets while the cartons occupy one of the said positions of rest, said batch feeding means comprising an intermittently operated conveyor driven in timed relation to said firstnamed conveyor.

6. In apparatus for feeding cigarettes to a double pocket carton adapted to receive two batches of cigarettes, the combination with means path terminates.
