No. 15073.—2nd July, 1902.—THE AMERICAN TOBACCO COMPANY, a corporation organized and existing under the laws of the State of New Jersey, having their place of business at 111, Fifth Avenue, New York, United States of America (assignees of Karl Harnisch, of St. Petersburg, Russia, Technical Engineer). Improvements in machines for forming cigarette tubes and the cigarette-tubes formed thereby.

Extract from Specification.—This invention relates to a certain class of machines for forming cigarette-tubes in which the mouthpiece-material is fed to the mouthpiece-forming mechanism by constantly running rolls, one of which has a segmental feeding-surface so that the mouthpiece-material is given an intermittent movement, the length of which corresponds to the length of the segmental surface. With this construction it is not possible to vary the amount of feed of the mouthpiece-material except by removing the segmental feed-surface referred to and replacing it with another of different length. It is usual, furthermore, in machines of this class to transfer the cut cigarette-tube length in which the mouthpiece is to be inserted from a position in front of the tube-forming device to a position in front of the mouthpiece-inserting mechanism by means of a forked pusher. After the tube-length has reached its position in front of the mouthpiece-inserting mechanism it is to be given up by the pusher to a forked holding-device, the function of which is to hold the tube during the operation of the mouthpiece-inserting mechanism. This forked holding-device is provided with a pair of narrow tines which in practical operation only hold the cigarette at two diametrically opposite points. The employment of the forked pusher and the holding-device not only increase the number of parts of the machine, but is further objectionable because the tube-length is liable to twist or slew in the forked holder, so that the mouthpiece does not enter the tube. Furthermore, some machines of this class have been equipped with devices for inserting a wad or plug of cotton in the mouthpiece, the function of the cotton being not only to prevent the tobacco, which is afterwards inserted in the tube by a stuffing-mechanism, from being pushed too far into the tube and thus passing into the mouthpiece-chamber, but also to purify the smoke, a portion of the nicotine being retained by the cotton. The cotton-inserting mechanism which has been heretofore used operates to insert a small piece or plug of cotton into the mouthpiece after the mouthpiece has been formed and inserted into the cigarette-tubes by pushing the cotton through the open end of the mouthpiece. When cotton is not used in the cigarettes the tobacco may be retained in the tube or shell by a series of tongues which project inwardly from the mouthpiece and form a retaining-wall, having a central orifice which prevents the tobacco in the cigarette from passing into the mouthpiece, but permits the smoke to be drawn therethrough. These retaining-projections have been heretofore formed by means of pivoted cutters, which have been of such a shape that the projections produced thereby are generally rectangular in outline. The cutters referred to operate upon a strip of mouthpiece-material which is fed to them, and which is afterwards cut up into blanks. When, however, a blank which is provided with these rectangular projections is rolled up or coiled into a mouthpiece the projections necessarily overlap. The result is that they do not fall readily into position, and do not therefore form a perfect retaining-wall. Furthermore, it is necessary in the practical manufacture of cigarettes that the projections referred to, before the blanks are rolled up into mouthpieces, be given a bend which is preferably greater than a right angle so that the projections underlie the edge of the material. In the constructions heretofore employed the cutters have been depended upon to bend down the tongues, and it has been found difficult to so arrange the construction that the cutters both cut the material and effect the bending. In making cigarettes with mouthpieces, the mouthpieces are formed by a mechanism which rolls a blank up into tubular shape, the rolled blank being then inserted into the end of a cigarette-tube. The mouthpiece thus formed is usually slightly smaller than the tube, and it is customary in the better class of cigarettes to subject the mouthpiece to a rerolling operation, which is performed by a mechanism which tends to unroll the blanks slightly so as to cause it to fit snugly in the tube. The present invention has for one of its objects to produce an improved feeding-mechanism for the mouthpiece-material which shall be certain and efficient in its operation and which shall be readily adjustable so that different lengths of mouthpiece-material may be fed when desired. A further object of the invention is to improve and simplify the mechanism by which the tube-lengths are transferred from the tube-forming mechanism to the mouthpiece-inserting mechanism and held in position while the mouthpiece is inserted. A further object of the invention is to improve the devices by which fibrous material, such as cotton, is positioned in the mouthpiece. A further object of the invention is to produce an improved cutting-mechanism for forming the projections on mouthpiece-material which operates to give a pointed form to said projections so that they come readily into position when the mouthpiece is rolled up. A further object of the invention is to produce an improved mechanism for bending the projections on mouthpiece-material after the projections have been formed and prior to the time when the mouthpiece is rolled up. A further object of the invention is to produce a cigarette-tube provided with an improved means for preventing the tobacco from passing into the mouthpiece. A further object of the invention is to produce a mechanism by which mouthpieces may be rerolled between a mandrel, or similar device, which is inserted into the mouthpiece after the same has been placed in the tube, and a co-operating rolling-surface acting on the exterior of the tube and mouthpiece. A further object of the invention is to generally improve the details of construction of cigarette-tube-forming machines, thus cheapening their construction and rendering them more certain and efficient in operation.
