CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 632,933, dated September 12, 1899.

Application filed December 29, 1897. Serial No. 664,459. (No model.)

To all whom, it may concern:

Be it known that I, FRIEDRICH EDMUND ZSCHERNIG, machine manufacturer, of Dresden, in the Kingdom of Saxony, German Empire, have invented certain new and useful Improvements in Cigarette Machines, of which the following is a specification, and for which a patent has been obtained in Germany, N0. 93,4:42, dated February 25, 1896.

The present invention has reference to a machine by means of which the tobacco which is shot in loose is turned out as a permanently elliptical paper-wrapped cigarette-rod, which is then cut up into single cigarettes which preserve their elliptical shape after beingcut up without anysubsequent pressingbein g required. For this purpose itis absolutely necessary in the first place that the tobacco fibers be laid together in an elliptical form in cross-section at the outset and not first in a" cylindrical or quadrangular rod and then afterward converted to an ellipticalform by pressure. To produce the rod of elliptical crosssection, I submit the loose tobacco to a drawing action as it passes from the bottom of a trough between guide-plates with tapering grooves underneath a drawing-disk. By the operation of these parts the tobacco for forming the rod is positively brought to an elliptical form in cross-section, the tobacco fibers being under uniform pressure throughout the rod both at the minor and major axes of the ellipse. From this it results that the fibers have no tendency to separate from each other, as is the case when a cylindrical or foursided rod is formed into an elliptical one by pressure. It is also necessary that the beltfeed for supplying the cigarette-paper, as also this latteritself, should be carefully protected from any lateral motion, in order that the gummed edge of the elliptical cigarette may always be parallel to the sides thereof. The tobacco rod is brought to its elliptical form before the closing of the paper wrapper is effected. The closing down of both edges of the wrapper around the rod being uniform and simultaneous, there is no unequal pressure put upon it, so that the elliptical section of the cigarette-rod is unchanged and the form of the cigarette remains permanent. v

In the accompanying drawings there is shown a construction of cigarette'machine for carrying out the above object.

Figure 1 is a front View, Fig. 2 a plan, and Figs. 3 to 12 sections on the correspondinglynumbered lines shown in Figs. 1 and 2.

The cigarette-paper with the tobacco thereon is drawn in through the charging and shaping troughs a a, which are of semi-elliptical transverse section by means of an endless band or belt as usual. The charging-trough is somewhat larger than the shaping-trough a, and these troughs are connected together by slanting lateral walls, as seen in Fig. 2, (plan View.) The charging trough a is heightened by sloping guide-plates or side walls Z), which at their lower edges serve as a guide for the paper as it is drawn through the trough. For this purpose adjustable bars 5 are mounted in longitudinal slots between the walls I) and the points of attachment, as seen in Fig. 3, and against the lower edges of these bars I) the edges of the paper lie, so

a that it is elt'ectually prevented from lateral movement during its travel. As the belt also is easily liable to sidewise movement on passing over the tapering junction betwee n the charging and shaping troughs, there are pro vided'at this junction of the troughs adjustable belt-guides 0, Figs. 1 and 3, with small hooks projecting into the trough a, which loosely hold the edges of the belt and so prevent any tendency to sidewise motion on the part of the latter.

The walls I) are furnished on the lower parts of their interiors with guiding-cheeks 5*, between which runs a drawing-disk d, which receives motion from the machine proportionate to the speed of the belt and the paper, and beneath which disk the charging-trough a merges into the shaping-trough a. The cheeks 17* are provided in their lower parts with grooves for guiding the tobacco, which grooves by reason of their peculiar form, as will be seen in Figs. 3 to 6, cause the tobacco to be drawn in under the pressing or drawing disk (1, which is adjustable by means of a screw. This disk cl has a milled groove cut in its periphery corresponding to the shape of the cigarette. By means of this drawing-disk coacting with the specially-shaped guidinggrooves in the cheeks 19* the tobacco is at once brought to the desired sectional form, thus producing a regular feed and shaping the tobacco rod in such manner that the pressure put upon all the tobacco fibers in every direction of the section is absolutely uniform. During the passage of the tobacco fibers through the entrance formed by the drawingdisk 11, charging-trough a, and the grooves of the cheeks 19*, from which the tobacco is now ready to receive its elliptical form, the tobacco fibers massed together in the form of a rod are caused to aggregate in such a way as they pass along that the elliptical shape is actually imparted to them at this particular point. The tobacco therefore arrives in the shaping-trough from the entrance above described already in its elliptical form, so that the'chamber in which the wrapping then takes place has only to maintain that shape.

On each side of the disk in the trough a there is sufficient room left to allow any laterally escaping fragments (or grains) of tobacco to remain inside the wrapper Without the paper becoming torn in its onward course. Behind the drawing-disk d is mounted an adjustable closer 6, Figs. 1, 2, and 7, which bears with its sharpened end against the disk and serves also as a scraper. This closer 6 also serves the purpose of preventing the tobacco from escaping, and the still vertical edges of the paper are also guided by the sides of the closer 6. One of the projecting edges of the paper is gently pressed against the pastingdisk g by a sloping fingerf, so that the disk may apply an even coating of paste to its outer edge. The finger f is mounted on an arm f, movable in one direction sidewise to allow of the finger being thrown out of contact with the paper.

Behind the pasting device is situated a feeddisk h adjustable through a screw h and having a smooth groove cut in its periphery corresponding to the form of the cigarette. This disk serves the purpose of maintaining the onward feed of the rod of tobacco formed by the drawing-disk, together with the paper, and also to prevent jamming in the wrapping-chamber in front. Against the disk h bears the guide-finger i, one end of which acts as a scraper on the feed-disk h and the other end projects into the tobacco-wrapping chamber. This finger is pushed between two smallblocks 2" and heldin position by a clamping-screw 2' The clamping-screw 2' works in a holder 1 pivotally connected to a rigid bracket, so that by unscrewing the screw 11 and swinging the holder 11 outward the finger 41 may easily be changed. By reason of the form given to both sides of the finger i the simultaneous folding down of both vertical edges of the paper in the wrappingchamber is insured while the form of the finger at bottom preserves the tobacco in the form which it possesses when entering the trough, so that any alteration of this form during the operation of wrapping by means of the cover-finger or the upper part is of the wrapping-chamber cannot take place. By the peculiar form of the grooves provided in the cover-finger is the edges of the paper supported by the sides of the guide-finger z are so guided that they simultaneously close round the tobacco, as seen in Figs. 8 to 11. It will be seen from these figures that the tobacco, by reason of the simultaneous folding of both edges of the paper, does not receive a one-sided pressure at its edges, and thus the cigarettes to be cut ofi after the complete closure of the pasted joint behind the guidefinger (see Fig. 12) permanently maintain the elliptical form imparted to them in the machine.

What 1 claim as my invention is In a cigarette-machine for the manufacture of a cigarette-rod of a permanently elliptical transverse section,the combination of a charging-trough a, a shaping-trough a, slanting lateral walls 1) connecting said troughs,cheeks If contained within said walls and having in them grooves of gradually-converging curved transverse section ,ad j ustable bars I) arranged outside of said walls for guiding the edges of the paper, belt-guides 0- adjustable to said walls, a drawing-disk drunning between said cheeks, and means for rotating said disk, all substantially as herein described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
