This invention relates to improvements in cigarettes and in their method of manufacture. V r

The general object of this invention is to provide a cigarette including means to direct the smoke thereof through the cigarette in a spiral course.

Another object of the invention is to provide a cigarette made with tobacco wherein the tobacco strands are twisted or in spiral formation.

Other objects and the advantages of this invention will be apparent from the following description taken in connection with the accompanying drawing wherein:

Fig. 1 is a perspective view of my improved cigarette showing a portion of the wrapping removed.

Fig. 2 is a diagrammatic view showing an apparatr. for making my improved cigarette.

Fig. 8 is an enlarged fragmentary section taken 0 inc 3-3 of Fig. 2.

Fig. 4 is an enlarged section taken on line H of Fig. 2. Fig. 5 is an enlarged section taken on line 55 of Fig. 2.

Fig. 6 is an enlarged section taken on line 66 of Fig. 2. Fig. '7 is an enlarged section taken on line of Fig. 2 and Fig. 8 is an enlarged section taken on line 8-8 of Fig. 2.

Referring to the drawing by reference characters. I have indicated my improved cigarette generally at 10. As shown the cigarette 10 is similar in general appearance to the standard typecigarette and includes a tubular casing 12 having a filler 13 therein. The casing 12 may be made of any type of paper commonly used for cigarette wrapping. The filler 14 is made of tobacco with the strands twisted in spiral formation as indicated by the strand shown in a heavy line at.

l-l in 1. By making the filler 13 in spiral formation as shown the sum of the lengths of the strands of tobacco is greater than if the tiller was formed of straight laid strands while the number of strands is less.

When the cigarette 10 is lighted the ends of the tobacco strands burn with a rotary direction as the burning front recedes and when the smoke therefrom is drawn through the cigarette from the lighted end to the mouth the tobacco strands direct the smoke in a V spiral course. Thiscauses the smoke to travel a greater distance than if it merely passed through the cigarette in a straight line and thus the smoke has a greater length of time to cool oif between the lighted end and the unlighted end.

In Figs. 2' to 8 inclusive, I have shown diagrammatically a machine of novel construction which produces my cigarette by a novel method. As shown tobacco 15 is fedinto a tray 16 from a hopper 17. The tray 16 is inclined'downwardly towards a vertical funnel member 18 and is resiliently supported as indicated at 19. The tray 16 is adapted to be vibrated by a'plurality of cam members '21 to cause the fibresof the tobacco to lie longitu- 7 dinally inthe tray and feed into the funnel member 18 in longitudinal alignment. From the funnel member 18 the tobacco passes into a twisting tube 22 which may be rotated by H a worm gear 23 from a worm pinion 24:. Adjacent the lower end thereof the funnel member 18'include's a plurality of inwardly directed prongs 25 and the twisting tube 22 includes similar prongs 26. The prongs 25 in the funnel member 18 restrict rotation and aligns the tobacco as it passes downwardly therein while the prongs 26 in the twisting tube 22 engage the strands of tobacco and-- twist them about the axes ofthe tube thereby forming the tobacco into a'spirally formed column 27 which emerges from the'tubes 22 into a U-shaped channel of paper 28' (see Fig. 8). i

The paper 28 is shown as fedfrom alroll 29 onto a'continuously moving belt 30 which conveys the paper through a forming machine 31 wherein it is gradually shaped from a flat strip as shown in Fig." 8. After thepaper emerges from the forming machinej31 the twisted tobacco member 27 is laid in the paper trough and the belt 30 carriesthe' paper 28 and the tobacco rope 27 through a closing andseaming device 32 which may be of any desired construction wherein the paper is closed around the twisted'tobacco column and sealed. The tobacco emerges from the closthe strings or threads extend in a spiral, and

ing and sealing device 32 completely encased enclosing the filler in a wrapper.

in a paper tube as indicated at 33. The belt then conveys the member 33 through a cutting device 34: which may be of any desired construction and wherein the member 33 is cut into cigarette lengths. The, belt 30 then expels the finished cigarettes into a chute 35.

The tobacco being laid in twists causes the burning particles to ac vance in a circular course. ous blends of tobacco to become better mixed thus resulting in a better flavored smoke. The smoke in my cigarette travels a circular course, it has a longer distance to go and thus has" more: time to cool ofi, Also, as the burning moves longitudinally and circumferentially' there is a longer interval. of burning and consequently each cigarette lasts longer than the ordinary cigarette but at the same time no more tobacco is employed in making the cigarette. Furthermore, since the tobacco is laid in twists it makes astronger and more rigid cigarette because the twist causes the strands of tobacco to contact one another and thus increases the strength and also causes a more even burning.

lVith the tobacco laid in. a twist the very fine particles which break off from the strands are held by the twist and are not drawn intothe mouth. With my cigarette, duetothe strength given the cigarette by twisting, a lighter weight cigarette paper maybe used, which is advantageous because it requires that less paper be burned.

From the foregoing descriptionit will be apparent that I have provided a novel method and apparatus for making a novel cigarette.

Having thus described my invention, I claim:
