Definitions

  • My invention relates to tobacco spreaders for cigarette making machines which include a tobacco feed drum and a tobacco scraper drum within a tobacco hopper or other container.
  • a tobacco layer or carpet is formed upon the feed drum and the scraper drum rotating in a direction opposite to that of the feed drum is arranged to brush over the surface of the tobacco carpet carried by the feed drum and to brush back any surplus tobacco which may be carried thereby.
  • My invention refers more particularly to means for tamping or compressing the said tobacco layer or carpet to a homogeneous density so that the same will be even and uniform.
  • the object of my invention is to avoid the said disadvantages and other disadvantages which will appear from the following description of an illustrative embodiment of my invention.
  • the essential feature of my invention consists therein that the tamping and raking operations are performed by the same operational member.
  • I use compactors, tampers or the like which are provided with raking projections and which in addition to the up and down movement for the tamping operation perform a timed swing movement away from and back towards the scraper drum.
  • I use tamping bodies or other compacting bodies which are provided with raking projections and are pivotally connected to a reciprocating supporting member, the pivotal connection permitting said tamping bodies to swing away from and back towards the scraper drum in the interval between two succeeding tamping operations so that during the first part of said swing movement the raking projections upon the tamping bodies disperse and trim accumulated surplus tobacco.
  • the pivotal connection between said supports and said tamping bodies will permit the latter to adjust their position during the tamping 2 operation to effectively conform to the surplus tobacco heaped up in front of the bite of the drums.
  • FIG. 1 shows a side view of my new tamping device
  • Fig. 2 a top view thereof.
  • Fig. 3 a side view of a tamping body in an intermediate position during its swing movement and of the adjoining parts of the driving mechanism
  • Fig. 4 a detail later more particularly referred to.
  • the tobacco spreader illustrated in Figs. 1 and 2 comprises a carded tobacco feed drum 2and a carded tobacco scraper drum l which are arranged within a hopper or other storage chamber not shown in the drawing.
  • the scraper drum 1 which rotates in a direction opposite to that of the feed drum 2 brushes over the surface of the tobacco layer or carpet carried by the feed drum 2 removing any surplus tobacco which may be carried thereby.
  • the said rollers may be driven in any convenient manner.
  • the tobacco in front of the bite of said rollers I and 2 is compressed against the carding of the feed drum 2 by a plurality of tapers or other compactors 8 which are raised and then permitted to fall upon the tobacco layer.
  • Each of these tampers 8 is supported at the end of the longer arm of one of a plurality of swing levers, two such levers 4 and 5 being shown. These levers are rotatably mounted upon the shaft 3 which is parallel to the axes of said drums l and 2.
  • Each swing lever is formed by two parallel fiat irons or the like.
  • the shorter arms thereof are connected by a cross plate 6 and the longer arms thereof by a pin 7 which pivotally supports one of said tampers or compactors 8.
  • the said swing levers 4, 5 perform a reciprocating movement about the shaft 3 so that the tampers 8 move up and down and perform the required tamping operation upon the tobacco layer carried by the feed drum 2. Neighboring swing levers 4, 5 perform said reciprocating movement alternately that is one lever swings upward while the other lever swings downward and vice versa.
  • tamper 8 attached to the swing lever 5 is shown in its lifted position and the tamper 8 attached to the swing lever 4 in its position at or near the end of the downward tamping with one end eccentrically connected to said 1 sprocket wheel 24 and. with its other end to a crank web 22 which is fixed to said shaft 3 im parting to the same the said rotational swing movement;
