Definitions

  • This invention relates to distributors for tobacco rod forming machines, and more particularly to a device to be used therewith for returning to the distributor any short tobacco which has separated from the tobacco supply of the distributor.
  • the object of the invention is to utilize short tobacco in the manufacture of tobacco cigarette rods.
  • the invention consists in the provision of means attached to or built as part of a cigarette tobacco supply and distributor, to receive the short tobacco and'convey it to the proper place to be guided with the tobacco to. a cigarette rod forming machine.
  • the invention also consists in the novel means for conducting the short tobacco so that it may receive the same, and hold it without loss in the conducting thereof, until it is discharged at the proper place.
  • novel means are in the form of interlocking and intermeshing cups forming .a continuous band, and the invention also consists in the control of the discharge of the tobaccco from these cups.
  • Figure 1 is a vertical longitudinal section showing generally a known distributor with the improvement forming the present invention indicated indotted lines, which cooperate withV certain novel parts in full lines;
  • FigureA 2 is a similar section but partial and enlarged, showing 'the details of; the improved parts forming this invention', the section being taken on line 2-2of Figure 3;
  • Figure 3 is a vertical transverse section taken on line 3-3 of Figure 2,v seen in the direction of the arrows;
  • Figure 4 is a partial side view of the improved conveying means for thevshort tobacco
  • Figure 5 is a plan view of Figure 4.
  • Figure 6 is an enlarged longitudinal sectional detail of the cups forming the endless conveyer
  • Figure 7 is an enlargeddetail view in side elevation of one of the cups.
  • the tobacco supply I is engaged by rotating cylinder 2- which has projections adapted to pick up and carry the tobacco supply I, and
  • a stamper 44 is disposed in the b-ight of the cylinders 2 and 3a.
  • a toothed wheel or cylinder t3 cooperates with the stamper lll.

  • the loose or short tobacco descending as indicated along the wall 39 drops upon the wheel or cylinder 2. and being intermingled with the long tobacco, drops upon the apron 3.
  • the means for operating the various parts are the following:
  • the motor 5I drives a belt 52 passing over the pulley 53. as shown in Figure l..
  • This pulley 53 is on a shaft 54 to which a gear 55 is secured, which gear 55 meshes with the gear 55 on a shaft 51 to which another gear 58 is secured.
