This invention relates to portable manually operable cigarette making machines, one problem is the number of moving parts any reduction of these parts reduces the cost of the machine and the wearing of these parts. These machines have two basic functions controlled by a single drive handle, the first controls compaction of tobacco, the second ejection of tobacco. The compaction function is improved by two alternative cam arrangements interacting with the compactor. In one embodiment, a stud moving in an internal cam raceway controls all cam motion, this greatly simplifies backward and forward motion of the compactor, preferably the stud is a roller stud. In the other embodiment, an internal cam cooperates with an internal cavity of the compactor. In both embodiments movement of the handle drive, first moves the compactor forward, then the compactor remains stationary, while further motion of the handle ejects the tobacco. This not only reduces moving parts hence complexity and wear, but also reduces tobacco dust infiltration, which tends to clog the machinery.
