CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 498,762, dated June 6, 1893. Application filed May 13. 1892. Serial No. 432,915. (No model.)

form of a continuous web is wrapped around a continuous filler and its edges unit-ed, after which the wrapper and filler therein are out into suitable lengths to form cigarettes. In machines of this class, the edges of the wrapper have generally been united by being overlapped and secured by pasting, and difficulty has been found in drawing and securing the wrapper about the tobacco with sufficient tension to make the cigarette as solid as desired.

The object of the present invention is to provide an improved machine by which a cigarette having a smooth outer surface may be produced and the wrapper drawn about the tobacco with sufficient tension to make the cigarette as solid as desired. 1 attain this object by turning the edges of the wrapper inwardly so as to form a rib extending longitudinally of the cigarette within the tube formed by the wrapper and securing the inwardly turned edges of the Wrapper together preferably by pasting and the pressure of suitable guides, the cigarette then being preferably pressed so as to flatten down the exterior of the seam thus formed.

For a full understanding of my invention a detailed description of a machine of the preferred form embodying the same will now be given, in connection with the accompanying drawings forming a part of this spocification and the features of construction forming the invention specifically pointed out in the claims.

In the drawings-Figure 1 is a vertical sectional elevation of so much of a cigarette making machine as is necessary to illustrate the application of the present invention thereto. Fig. 2 is a plan view of the same. Figs. 3 to 10 are cross-sections on respectively the lines 3 to 10 of Fig. 1 looking to the left.

Fig. 11 is a cross-section of the completed cigarette, and Fig. 12 is a plan view of the pasting devices. Fig. 13 is a cross section on a much larger scale showing a modification. Fig. let is a detail plan view of the same. Fig. 15 is a detail longitudinal section of the same taken between the internal guides, and Fig. 16 is a view similar to Fig. 13, showinga modification in the devices for securing the wrapper.

Referring to said drawings, plate or table of the machine which supports the operating parts, and B the carrying belt by which the wrapper 0c and filler y are advanced, the filler passing onto the wrapper from a filler forming mechanisrn'of any suitable form, or being formed by hand. The belt B is carried by belt rolls 1O driven in any suitable manner, a pulley 11 on the rear roll 10 being shown for this purpose. As the wrapper with the filler thereon is advanced'by the belt B, the side edges of the wrapper are turned upward by external side guides 1, 2 on opposite sides and the filler is pressed and compacted by means of grooved roller 12 lying inside the upturned edges of the wrapper between the guides 1, 2 this roller being driven by a belt 13 as shown, or in any other suitable manner. In advance of the pressing roll 12 a bracket with an overhanging arm 14. is mounted on the bed plate, and carries two internal guides or fingers 3 extending in the line of movement of the filler inside the guides 1, 2 and turned up edges of the wrapper and gradually converging as shown in Fig. 2 so as to be close together at their forward ends. These guides 3 are preferably formed as shown of narrow plates resting fiatwise upon the filler as shown in Figs. 5 and 6, and extending forward from the bracket 14: and gradually changing to the circular form shown in Fig. 7 as the edges of the wrapper are carried inward between them, and then flattened vertically so as to form extended pressing surfaces for pressing the edges together as shown in Figs. 9 and 10. It will be understood,however, that the guides need not be of the special form shown, but converging bars or rods of uniform shape throughout may be used. The guides 1, 2 are curved inward gradually over the fingers 3 so as to bend the edges of the wrapper inward and downward between A is the bed the guides 3 as shown in Figs. 6, 7 and 8, the side and internal guides acting to draw the Wrapper tight about the filler by thehold upon the inturned edges. When the edges of the Wrapper have been carried inward between the guides 3 into the position shown in Fig. 8, the side guides 1, 2, terminate. The converging guides 3 are still a short distance apart and paste is now applied between them preferably to both edges by the pasting device shown in Figs. 1, 2, 9 and 12 and constructed as follows. Above the fingers 3 is mounted on an arm 15 on the base plate A a paste fountain 16 in which runs a thin disk 4 which engages the'paste so as to take up the latter on its side faces. The edge of this disk ilies between two disks 5 between which runs the paster formed of a thin disk, the side faces of which receive the paste from disks 5 and transmit it to the edges of the wrapper between the guides 3, as shown in Fig. 9. The disk 4 is driven by friction from disks 5, and the latter and paster 6 are driven by any suitable means, being shown as geared together by gears 7,8 and the shaft of paster 6 as driven by a belt 17.

It will be understood, however, that any other suitable pasting devices may be used, and that while I have shown both edges of the wrapper pasted, I may apply the paste to but one of the edges in which case one of the disks 5 will be omitted and the paster 6 take the paste on but one side.

As the cigarette is advanced from the pasting devices with the edges of the Wrapper pasted as described, the edges are brought together by the guides 3 the ends of which press the edges together firmly and thus secure them, as shown in Fig. 10. The cigarette with its wrapper thus secured maybe advanced by the belt B and any suitable feeding mechanism coacting therewith or independent thereof. I have shown a grooved roller 18 coacting with belt roll 10 and from the shaft of which the belts 13, 17 are driven, this shaft being driven by any suitable means, such as a gear 19 as shown. This roll 18 serves also to press down the top of the cigarette so as to flatten out the scam, the cigarette thus formed showing only a narrow line indicating the seam, as shown in Figs. 2 and 11.

In the construction thus far described, the edges are pressed together by the internal guides under spring pressure produced by the elasticity of the somewhat long fingers forming the guides. It may be found preferable,

however, to use rollers or similar anti-friction devices for pressing the edges together, and in Figs. 13, 14 and 15 I have shown such a construction in which the guides 3 are constructed to form supports a at their ends and rollers!) are mounted on vertical axes therein on opposite sides of the inturned edges, so as to press the edges together, as the edges pass between them. The supports a are preferably constructed as shown, so as to form a plate extending over the filler below the rollers,

thus pressing the filler down and forming a chamber inside the wrapper for the rollers. The form of the internal guides 3 in this construction is the same as in that previously described, except at the ends where the guides are developed into the supports for the rollers 9, as clearly shown in Figs. 13, 14 and Pasting devices Will preferably be used with this construction, as previously described, but the edges may be secured by crimp1ng, 1ndenting or perforating, the rollers 9 belng suitably formed for the purpose, as shown in Fig. 16.

It will be understood that modifications may be'made in the constructions shown without departing from my invention and I am not to be limited to the specific form of the devices.

It will be understood also that my-invention is not limited to cigarette machines, but the devicesshown are applicable also in other classes of machines for forming unfilled as well as filled tubes, and my invention includes such use of these devices.

By the expression turning the edges of the wrapper inwardly used in the claims, I mean that in folding the wrapper so as to form a tube inclosing the filler, the edges of the wrapper are turned inwardly on opposite sides so that the outer surfaces of the wrapper at the opposite edges are brought together, and the rib or projection formed by the two edges is upon the inside of the tube formed by the wrapper, as distinguished from constructions in which the edges of the wrapperare turned outwardly so as to bring the inner surfaces of the wrapper together at the opposite edges and form a rib or projection upon the outside of the tube formed by the Wrapper,
