Abstract

The invention provides a manual cigarette making machine of the twin roller and endless band type provided with an adjustable band guide member whereby the effective length of a tobacco and cigarette wrapper receiving band loop between the rollers may be altered and cigarettes of alternative diameters may be made. The guide member has a rib or node extending from a circular central portion, the member being mounted in end plates and having a lever at one end thereof for rotating the same. The rib or node has an edge which engages the internal surface of the band and upon rotation thereof, controls the size of the loop. The device includes a pair of band engaging rollers, one of which is mounted in J-shaped slots in the end walls so that it can be moved toward and away from the other to permit the formation of a tobacco receiving trough within the loop.

Claims

1. A manual cigarette rolling machine of the kind including an endless band manually rollable around and in contact with a fixed axis roller and a shiftable axis roller mounted in end plates of a casing, said band forming a tobacco and cigarette wrapper receiving loop between said rollers, the improvement comprising a guide member pivotally mounted in the end plates about a fixed axis and within the endless band, the said guide member having a radially extending camming surface in sliding contact with the interior surface of the band and further having a lever arm formed at one end of said guide member to enable rotation of said guide member between pre-set angular positions, said camming surface cooperating with said rollers to define a guide path for said endless band, said guide path having a length adjustable by rotataion of said camming surface of said guide means whereby the diameter of said loop may be varied.

2. A machine according to claim 1 wherein the said guide member comprises a cylindrical central body portion formed with a projecting rib.

3. A machine according to claim 1, wherein at least one end of the casing is made from a resilient material and has a substantially U-shaped slot therethrough to defne a resilient finger;

and wherein said guide member has a radial projection on an end thereof for engagement with and deflection of said resilient finger on movement of said guide member between its pre-set angular positions.

4. A machine according to claim 1, further including a generally U-shaped metal body having upright side walls defining grooves, and wherein the end plates are press-fit into said grooves.
