MARSHALL, MISSOURI, ASSIGNOR 0F ONE-HALF TO GLENN S.

NOBLE, OF CHICAGO, ILLINOIS SELF-IGNITING lCIGARETTE Application led January 22, 1930. Serial No. 422,620.

This invention relates to self-igniting cigarettes, and an object of the invention is to provide a striking head on the end of a cigarette WhichA When drawn across a friction'surfaee on the cigarette package will indirectly cause the tobacco filler to burn.

Another feature of the present invention is to provide a combustible disk between the striking vhead and the tobacco filler which will be of slow burning nature to insure the entire area of the tobacco filler, becoming ignited after the striking head has burned.

Another feature of the present inventionl is to provide a deflagrating adhesive about the `edges of the disk, that not only secures the disk to the Wrapper of the cigarette but progressively burns about the periphery 0f the disk so as to insure complete combust-ion of the disk and economize in the amount of material used in the striking head.

Another feature of the invention-is to provide a disk of the character referred to that will not allow the taste of any of the products of combustion of the striking head to permeate the tobacco and which is non-poisonous, that burns Without odor, and is entirely tasteless. v

Further objects o f the invention are to provide, in a manner as hereinafter set forth, a cigarette of the character referred to that is very simple in its method of assembly, thoroughly reliable for its intended purpose, having added utility Without marring the appearance thereof, that is strong, compact and durable, and that is comparatively inexpensive to manufacture. l

With the foregoing and otherobjects in view, the invention consists of a novel construction, combination and arrangement of parts as will be hereinafter more specifically ldescribed and illustrated in the accompanying drawings, wherein is disclosedI an embodiment of the invention, but it is to be understood that changes, variations, and modifications may' be resorted to Without departing from the spirit of the claims hereto appended.

In the accompanying drawings: Figure 1 is a perspective View of a cigarette package, partly broken away, and in accordance `with the present'invention,

l Fig. 2 is a perspective view of a cigarette formed in accordance with the present invention Fig. 3 is a vertical diametric 'section through the' cigarette,

Fig. 4 is an enlarged fragmentary, dia- .,metric section at the upper end of the cigarette, and

Fig. 5 is a perspective view of the pliant fibrous disk forming a part of the present w invention.

Referring to the drawings in detail, 6 indicates generally a package of cigarettes having a striking surface 7 on one side thereof. This striking surface 7 i's similar in all g5' respects to the striking surface of a match box preferably intended for safety matches.

The cigarette of the present invention includes a tobacco filler 8 confined in a tubular Wrapper 9 that may be of lpaper or the 70 like. Anchored in one end of the tubular wrapper 9 so that its outer face is approximately flush with the upper edges of the tube, is a pliant, fibrous disk 10 preferably formed of `blotting paperor other suitable 75 absorbent material. f

It will be apparent, that since the fibrous disk is pliant, that there is o possibility of breaking this disk during the packing or storage of the cigarettes. Furthermore, since the disk is fibrous in nature, itis porous and may permit a draft of air being drawn therethrough if the' smoker draws on the cigarette before the disc is consumed, but ordinarily the disc is burned almost instan- 95 taneously.

4Prior tothe insertion of this disk 10 inthe upper end of the tubular Wrapper, it is' soaked in saltpeter and dried so as to insure the burning of the disc over its entire area once it has been ignited.

^ The inner faceof the disk lOvis in contact with or in abutting relation to the/outer end of the tobacco filler 8, so that the burn'ingf the disk will ignite the tobacco filler. e peripheral edgev of the disk is coated with a deagrating or easily combustible adhesive,

by means-of which the disk is secured to the l inner Wall of the tubular wrapper 9 at the end'vthereof;

This deilagrating adhesive'is indicated at 11, and consists of glue mixed with a proportion of ysaltpeter that is suIicient-to give the deliagrating properties thereto. I prefer to use a glue or adhesive which will not 'have an objectionable odorl or taste when itis burned, as for instance, dextrin or other suitable vegetable compound.

The cigarette is rovided with a striking head 12, that is a apted to be rictionally moved across the' strip 7 to ignite the same similarly to the means` of igniting 'safety 'matchesrlihis strikin head 12 is placed in position to light the dlsc and adjacent parts and is preferably only contiguous with aportion of the circumference of the disk 10, and is preferably formed on one-half the'area of this disk. c y

v, It will be understood that the striking head is deposited on the end of the cigarette in the plastic statel in any suitable manner, whereby it adheres to and` anchors itself to the fiber otf the disk or to the disc, and adja.

cent portion of the wrap er.I

t In the application o the presentinvention, the head 12 is struck on the stri 7 whereupon this head bursts into ame. iame causes the disk 10 to burn in the area on which the head-is supported. At the,

same time, the deiagratin adhesive layer 11 about the'peripheryof t e disk is ignited and progressively burns about the entire j periphery of the disk, insuring that the disk 4will burn over its entire area'. v

'It will be understood that the disk being of a librous nature, will burn slower than the head or the deflagrating' adhesive. While the adhesive seals the upper end of the tube 9, it is also secured to the upper portion of the tube. llt therefore fellows that when the -dellagrating adhesive burns, it will also ignite the upper end of the wrapper, which insures a most perfect combustion of the f entire area of the-tobacco ller at the upper end of the tube.

Since the fibrous disk is odorless, tasteless and nonpo i sonous,it will be apparent that any fumes of combustion from the head 12will not permeate the tobacco filler, because the'head 12 is completely burned before the burning disk 10 ignites the tobaccofiller.

' It is to be understood that by describing' in detail herein any particular form, structure, or arrangement it is not intended to limit the invention beyond the terms of the several claims or the requirements of the prior art. i

' Having thus described my-invention, what i 1 claim as new is'z-f- 1. A self-igniting cigarette includinga tobacco filler and a wra per, comprising a lie brons Icombustible dis at lone end of the wrapper, deiiagratin'g adhesive on the edge of the disk for securing the latter to the.

hev

head applied to the closed end bf the ciga- 5 rette, which head is adapted to be ignited by friction on a suitable surface.
