Abstract

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.

Dependent claims

A machine for compacting a batch of tobacco into a generally cylindrical body, then injecting said cylindrical body into a tube to form a cigarette, comprising a frame;

a first compacting member and a movable second compacting member, said members having faces defining between themselves a tobacco receiving chamber having first and second ends, said second movable member normally spaced apart from said first member;
a shaft turnably mounted in said frame forming a fixed pivot axis;
an actuating member turnable about said axis in an arcuate path between a first position, through a second position to a third position;
cam means turnable about said fixed pivot axis by said actuating member, said cam means having an internal raceway, and stud means on said second member, engaged by said internal raceway, said cam means acting directly on said second member and urging said second member toward said first member when said actuating member moves from said first position toward said second position, whereby the volume of said chamber is reduced and a batch of tobacco contained in said chamber is compacted by said faces into a substantially cylindrical body;
said cam means, internal raceway, and stud means combining to urge said second member away from said first member when said actuating member moves from said second position toward said first position;
tube supporting means aligned with and communicating with one end of said chamber;
and means for expelling said compacted body from said chamber comprising a plunger located at the other end of said chamber and motion transmitting means connected to said plunger, so that when said actuating means moves from said second position toward said third position, said plunger is moved through said chamber expelling the body through said tube supporting means into a tube mounted on said supporting means.

a first compacting member and a movable second compacting member said members having faces defining between themselves a tobacco receiving chamber having first and second ends, said second member normally spaced apart from said first member;
a shaft turnably mounted in said frame forming a fixed pivot axis;
an actuating member turnable about said axis in an arcuate path between a first position, through a second position to a third position;
cam means turnable about said fixed pivot axis by said actuating member, said cam means being internal of a cavity of said second member, said cavity having walls, said cam means being adapted to be in cooperating contact with said walls, said contact urging said second member toward said first member when said actuating member moves from said first position toward said second position, whereby the volume of said chamber is reduced and a batch of tobacco contained in said chamber is compacted by said faces into a substantially cylindrical body;
said contact urging said second member away from said first member when said actuating member moves from said second position toward said first position;
tube supporting means aligned with and communicating with one end of said chamber;
and means for expelling said compacted body from said chamber comprising a plunger located at the other end of said chamber and motion transmitting means connected to said plunger, so that when said actuating means moves from said second position toward said third position, said plunger is moved through said chamber expelling the body through said tube supporting means into a tube mounted on said supporting means.
