Abstract: 410,149. Cigarette-making machines. WIX, A., 338, Goswell Road, London, and MAY, R. F., 9, Manor Road, Potters Bar, Middlesex. Aug. 12, 1932, No. 22660. [Class 130.] In the manufacture of cigarettes having inserted filter tips by means of a stationary spoon through which a continuous rod of tobacco is advanced, the paper tube is moved into engagement with the fixed spoon by a reciprocating spoon through which the filter tip is introduced into the other end of the cigarette. The movable spoon 6 is shown mounted on a carriage 5 reciprocated by a rod 7 along the base member 1. When the carriage is at the right-hand end of its movement, a filter tip 9 is introduced from the tip-forming apparatus 4 partly into the spoon 6 as shown. As the carriage moves to the left, the spoon 6 enters the end of the paper tube 10 carried by an intermittently rotatable drum 11, and pushes the tube on to the fixed spoon 2, through which a rod of tobacco is advanced to provide the filling 15 of the cigarette. During this movement, a circular disc 18<a>, carried by a lever 18 pivoted on a spindle 17, is moved to one side of the spoon 2, so that as the arm 18 is moved along the spindle 17 by the carriage 5, the disc 18<a> passes the spoon 2 at the side thereof and enters a slot formed in an oscillating cutter 21, which is also pivoted on the spindle 17. The cutter is then swung over to sever the charge 15 from the tobacco rod, and thus brings the disc 18<a> into alignment with the spoon 2, the disc during this movement being advanced out of the slot in the cutter by a spring 17<a>, as this is allowed to act by means of an incline 16<c>. The carriage is then moved back towards the right, whereupon the disc 18<a> presses the charge 15 of tobacco against the filter tip 9, and also removes the cigarette from the spoon 2. Continued movement to the right brings the filter tip 9 against an ejector arm 12, which enters a slot in the top of the spoon 6, so that the filter tip is fully inserted into the cigarette, which is then pushed off the spoon 6 and is held supported in the space between the two spoons by the disc 18<a> and ejector 12 pressing on opposite ends. In the final movement of the carriage to the right, a stop 5<a> thereon engages a stop 13<c> on a lever 13 carrying the ejector 12, which is thus released from the cigarette, allowing same to be discharged. The spindle 17 is mounted in a slide 16, which is moved to the left, after the carriage 5 has completed a part of its movement to the left, by the engagement of a stop 5<c> on the carriage with the slide 16, the return movement of the slide being effected by a spring 16<a>. During this movement of the slide 16, the end 18<b> of the lever 18 slides in a guide 19, which when the carriage is moving to the left is raised, by cam actuation rods 19<a>, so as to give the motion of the disc 18<a> described above. On the return movement of the carriage, the guide 19 is kept stationary, so that the disc 18<a> moves straight through the spoon 2. The slide 16 may be mounted on the base 1 instead of on the carriage 5.
