DEVICE FOR CONTROLLING THE DBAVFOFF HGOK CARRIED BY THE FILLING MEMBER IN CIGARETTE-FILLING ll/IACHINES.

Application filed September 25, 1924, Serial No. 739,802, and. in Germany January 11, 1924,

My invention relates to improvements in devices for controlling the draw-off .hook carried by the filling member in cigarette filling machines.

In the ordinary cigarette filling machine a hook is employed for removing the completed and filled cigarettes from the beak or finger, and this is generally accomplished by a slide to which the hook is connected and which also carries the plunger for feeding the cigarette cases to the beak, and it is necessary that the plunger and the hook move together in I the longitudinal direction of the axis of the cigarette, and also movetransversally.

The object of my invention is to provide means for longitudinally moving the slide and at the same time to impart the longitudinal and rocking movement to the beak or finger and also provide means whereby the slide is held stationary when the beak or finger is operating on the completed cigarette.

Another object of my invention is to provide means whereby the movement of the plunger is in a definite relation to the movethe hook so that the same will be moved without shock, this being necessary due to the extraordinary rapidity with which the separate members follow one another in the ordinary cigarette machine.

A further object of my invention is to provide a simple, imparting this movement to the slide and simultaneously imparting the same movement to'the hook and also imparting the rocking movement to said hook.

In the accompanying drawings Figure 1 is a side elevation of a cigarette machine showing my invention applied thereto.

Figure 2 is a'view similar tolligure 1 showing the parts in different positions.

Referring now to the drawings, A represents the frame of the machine which is provided at its upper end with a slide a working in the guide-way a and moving in a horizontal direction as clearly shown in the drawings; Carried by the slide a is a plunger 6 which pushes the cigarette cases out of the grooves u located in the periphery of the drum T onto the beak of finger c. Carried by the frame A is a horizontal shaft d driven in any desired manner and having secured thereon a cam disk 6. On the inner face of cheap and effective means for the cam disk 0, adjacent the frame A, there is provided a cam groove adapted to receive the horizontal outwardly extending pivot 9 carried by the lever f. The lever is pivoted at its lower end. at h to the frame a and its upper end is pivoted at i to the slide a, and thus it will be seen that as the cam revolves the lever f will be reciprocated back and forth by the cam groove on the inner face of the cam e and cause a reciprocating movement to the slide a. i s k Pivotally mounted at 70 on the end of the slide a is a double armed lever n. One arm Z of the lever extends outwardly over the drum T and carries the hook m which may be ad- 'iusted thereon by means of the set screw m. The other arm of the lever n has pivoted thereon at 0' a rocking link 0 formed with a slot pextending in the direction of its length and in which slides the block 9 capable of turning upon the shaft (Z. The rocking lever 0 has a pin 1* upon its inner face which enters the closed cam groove 8 provided on the outer face of the cam disk 0 whereby the lever may be rocked by the cam groove as will be readily understood from the drawings. The cam groove 8 as shown in Figures 1 and 2 of the drawings is formed with a portion 2? concentric with the shaft (Z for the purpose hereinafter more fully set forth.

Upon the rotation of the shaft d it will be seen that the cam groove onthe inner face of the cam 6 will move the lever f on its pivot h and thus move the slide a back and forth. The lover a is carried by the slide and will move back and forth with the slide.- Due to the fact that the lever oswings about the axis of the shaft Z a longitudinal movement of the lever takes places as the pin 1" slides in the cam groove 8. As soon as the portion 25 of the cam groove 8 moves in the path of the pin 1 upon the rotation of the came disk 6, the rocking lever is moved and the longitudinal movement of the lever by this portion of the groove imparts a rocking movement to the double arm 12 causing the hook m to be lowered to the beak 0 and upon the return movement of the slide a the completed cigarette is withdrawn from the beak.

Having thus fully described my invention what T claim is 1. A. cigarette machine comprising a rotary drum having cross-wise slots in its periphery for the reception of cigarette cases, a finger or beak positioned at one end of the drain, a reciprocating slide carrying a plunger for pushing the cigarette cases into engagement with the said beak, a rotary member for imparting a reciprocating 1novem'ent tosa'id slideand plunger, a lever pivotally mounted on said slide, a hook connected to one arm of said lever and adapted to reciprocate with the slide, and means connected to the other end of said lever and operated by therotary member torcausing the rocking of the lever to bring the hook into engagement with the end oi the cigarette while on said beak, and toraise said hook out of engagement with the cigarette after it has been removed from the slots in the rotary drum.
