To all whom t may concern.-

Be it known that I, WILLIAM H. BUTLER, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New 5 York, have invented certain new and useful Improvements in Methods ofv and Machines for Making Cigarettes, fully. described and represented in the following specification and the accompanying drawings, forming a part io of the same, and for which I have obtained Letters Patent in France, No. 235,268, dated January 3,1894; inItaly,No. 35,795/188, dated February 23, 1894; in Trinidad, dated June 26, 1894; in Barbadoes, No. 81, dated July 6, 1894; in Cape Colony, No. 376 or 6/678, dated July 12, 1894; in Natal, dated July 16, 1894; in South African Republic, No. 675, dated July 18, 1894, and in Austria, No. 45/2,150,

dated June 14,1895. zo This invention relates to that class of cigarette-machines in which the Wrapper in the form of a continuous web is Wrapped around a continuous ller and its edges united, after which the wrapper and the filler therein are 2 5 cut 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. A

The especial object of the invention is to provide a machine by which the wrapper may be drawn to the required tension and secured by a strong seam, andI secure this result by turning the edges of the wrapperoutwardly or inwardly and folding or rolling them together, and then pressing, crimping, 4o indenting, or perforating the rolled or folded together wrapper-edges to complete the seam,`

and I preferably employ a support inside the Wrapper, on, which the edges of the wrapper are pressed down, and which forms one member of the pressing, crimping, indenting, or.

perforating devices, so thatthe seam is formed flat upon the cigarette. Iprefer to secure the wrapper, as above described, without the use of paste; but my invention includes an improved method and mechanism for making 5o cigarettes having paste applied in connection with the formation of the seam.

For a full understanding of my invention a detailed description of a machine of the preferred formfor carrying out my improved method and embodying all the features of my invention will now be given, in connection with the accompanying drawings, forming a part of this specification, and the method and features of construction forming my in- 6o vention specifically pointed out in the claims.

In the drawings, Figure l is a vertical sectional elevation of so much of a cigarette- `making machine as isnecessary to illustrate the application of the present invention thereto. Fig. 2 is a plan view of the same.

Figs. 31:0 9 are cross-sections on respectively the lines 3 to 9 of Fig.p1, looking to the left. Fig. 10 is a detail of they crimping device preferably employed. Figs. 11 to 2O show a modi- 7o fied form of a machine in which the edges. of the wrapper are turned inwardly and the product of the same. Fig. 11 is a partial longitudinal section of the machine. Figs. 12 to 19 are cross sections of the same on re- 75 spectively lines 12 to 19 of Fig. 11, looking to the left.A Fig. 2O is a cross-sectionfof the completed cigarette. Fig. 21 shows a modication employing pasting devices. Fig. 22 shows a modified form of seam-closing worm. Fig. 23 8o shows a perforating device which may be used in forming the seam.

Referring to said drawings, A is the bedplate or table of the machine, which serves to support the operating parts. 8 5

B is kthe carrying-belt, by which the cigarette-wrapper x and filler y are advanced, the filler passing onto the wrapper from the fillerforming mechanism, of any suitable form or being formed by hand. The belt B is carried 9o by belt-rolls 10, driven in any suitable manner, a pulley l1 on the rear roll lO 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 9' 5 by guides 1 2 on opposite sides, and the filler is pressed and compacted by means of grooved roller 12, lying inside the turned-up edges of the wrapper in advance of the guides 1 2, and being driven bya belt 13, as shown, or in any other suitable manner.

In advance of the pressing-roll l2 a bracket with an overhanging arm let is mounted on the frame, and this arm 14 carries the interior support, which consists in the form shown of a finger 3, resting upon the filler inside the turned-up edges of the wrapperand extending in the line of movement of the filler. The support 3 is shown as consisting of a plate curved about the top of the filler and extending through about half its circumference, and this is the preferred form; but it may consist of a narrow, fiat, or curved plate or bar. The folder, by which the edges of the wrapper are folded over the filler and support 3 and overlapped, consists of two curved guides 4 5, carried by the arm 14, guide/1 extending only a short distance in advance of the arm 14, and acting to bend inward the upturned edge of the wrapper on one side and guide it until both upturned edges are within the control of the guide 5 on the opposite side, which draws the wrapper tight about the filler and support 3 and turns down the overlapping edges, and preferably is constructed, as shown,so as to fold or roll the edges together, a strong joint being thus formed when the edges are pressed down, even without crimping, indenting, or perforating. The operation of the guides 1 2 and 4 5,in connection with the finger 3, will be readily understood from Figs. 3 to S, showing successive stages of the operation.

Just in advance of the end of the guide 5 is mounted a grooved pressure-roller15,driven, as shown, by a belt 1G or in any other suitable manner, this pressure-roll coacting with the support3 inside the Wrapperto press down fiat the overlapped and rolled edges of the wrapper. It. may be found that the pressure of this roll is sufficient to secure the wrapper without other devices, orI may construct this roll so as to form a crimping, indenting, or perforating device, coacting with the support 3 to secure the wrapper, the support 3 being plain or formed with grooves, indentations, or perforations, into which the wrapperis pressed by the roller, or the roller may be plain and the support be provided with suitable devices for crimping, indenting, or perforating the paper against the roll. I prefer, however, to use the roll 15 only for pressing down the edges of the wrapper and to provide an independent crimping, indenting, or perforating device coacting with the support 3 in advance of the roll, and I prefer to use the device shown, consisting of a worm-wheel 17, mounted to rotate transversely to the cigarette-rod and driven by a belt 18 or in any other suitable manner. The threads of this worm-wheel 17 are preferably of a pitch corresponding to the movement of the advancing cigarette-rod, and preferably have quite sharp edges, by which the layers of the wrapper formed bythe overlapping edges are crimped and firmly secured together as thc cigaretterod passes the worm-wheel. The end of the support 3 may be plain and the wrapper be crimped simply by the pressure of the wormwheel against the plain surface; but I prefer to form the end of the support with grooves corresponding to the threads on the wormwheel, into which the Wrapper is pressed, as shown in Fig. 10. The thread ofthe worm 17 may be smooth or ronghened to form teeth or pins by which the wrapper is indented or perforated, as shown in Fig. 22, and the construction of the end of the support 3 may bc varied correspondingly. It will be understood, also, that the wheel and support may be formed in any other suitable manner, so as to crimp, indent, or perforate the wrapper by pressure between the wheel and support.

The continuous cigarette is advanced from the folding and crim ping, indenting, or perforating devices by the belt B and any suitable feeding mechanism coacting therewith or independent thereof. I have shown a grooved roll 19 coacting with belt-roll 10, and from the shaft of which the rolls 12 15 are driven, this shaft being driven by any suitable means, such as a gear 20, as shown.

NVhile it will be found that the wrapper is secured firmly without pasting by the devices shown, it is evident that I may use paste, if desired, and that my invention provides a very simple, convenient, and efficient method and machine for making pasted cigarettes. Thus in the construction shown it is necessary only to mount a suitable paste-fountain to deliver paste to the worm-wheel 17 or other crimping, indenting, or perforating device, the paste being transferred to the wrapper and pressed therein by means of the sharp edges of the worm-wheel or the teeth or pins of the indenting or perforating device, a very small amount of paste being thus sufficient. Such a construction is shown in Fig. 21, in which a paste-fountain 2l is mounted above the worm 17, and paste is delivered therefrom to the worm-wheel by fountain-roll 22 and paste-roll 23, the latter engaging the worm and being driven by friction or positively, as preferred.

In the construction above described the edges of the wrapper are turned outwardly to form the seam; butthis is not necessary, and I have shown in Figs. 11 to 2O a construction in which the edges are turned inwardly and then folded or rolled together and secured by crimping, indenting, or perforating. In this construction the roller 12 is preferably made convex, so as to form a recess for the guides by which the edges of the wrapper are folded or rolled together and the interior support against which they are secured. The exterior side guides a b are made continuous throughout and operate, as the guides 1 2 3 4.- of the construction previously described, to fold the wrapper about the filler; but their construction is Varied so as to coact with interior side guides to turn the edges lOD IIO

of the wrapper inward instead of outward. The interior guides c d are carried by thearm 14, and are gradually curved inward over the filler with the exterior side guides ab, the edges of the wrapper lying between the exterior and interior guides and being gradually closed over the filler. -The exterior guide t is provided with a wing 6, curving gradually inward and coacting with wings' 7 8 on interior guides c d, s0 as to turn -tWo edges of the Wrapper inward and roll or fold them together, as shown in Figs. 14 to 16. When the edges have been thus folded or rolled together, the guides a b c terminate, but the wing S of theguide d is prolonged and curved over the top of the filler, so as to form a concave finger e, whichvis the interior support against which the edges of the paper are pressed down and secured.

The position of the edges of the wrapper, after they have been rolled or folded together and released from the guides, and that of the interior support e, is shown in Fig. 17.

The roller 15 is mounted in advance of the ends of the guides, as in the construction previously described; but in this construction the roller is preferably made convex, so as to press down the folded or rolled edges of the Wrapper into the recess or chamber formed by the concave supporte, the wrapper thus being drawn tightly about the filler, aiding in securing the result desired of a iirm solid cigarette. The support e and roller 15 may be used to secure the wrapper together by pressure or by crimping, indenting, or perforating, as previously described; but in this construction, also, I preferably use the roller l5 only to pressdown the edges and employ an independent crimping, indenting, or' perforating device. These devices may be the same as previously described, consisting of a Worm 17, coacting with the end of the support e, which is suitably formed for this purpose; but I have shown a construction in which the support e is provided with a recess or holder, in which runs a roller 9, the recess and holder being preferably formed so that the roller is held therein without a shaft and rotates freely by friction with a roller 24, mounted and driven in any suitable manner. The rolls 9 24 may be formed in any suitable manner, so as to crimp, indent, or perforate the edges and secure them together, both of the rollers being of special construction for this purpose, or either one of them may be plain. It will be understood, also, that in place of the roll 9 I may use a ball mounted in the holder on the support or a Worm mounted in the holder, so as to rotate transversely to the travel vof the cigarette andcoacting with the worm 17, of the construction previously described.

In Fig. 23 I have shown a modified construction, in which the support 3 is provided with a series of small perforations registering with pins or sharp-pointed teeth on a roll 24 outside the wrapper.

The machine shown in Figs. 11 to 1.9 is

claimed specifically in a companion application, Serial No. 432,914, tiled May 13, 1892. It will be understood, also, that I may use any othersuitable devices for crimping,indenting, or perforating the edges of the Wrapper..
