Description

March 12, 1963 J. E. M. ALLEN 3,080,870 SELF LIGHTING CIGARETTE Filed Nov. 29, 1960 INVE N TOR John E. M. Allen Attorney are 3,080, SELF LIGHTING (IIGAEETTE dohn Earl Magwood Allen, Fenwiclr, @ntarro, Canada Filed Nov. 29, 1%0, Ser. No. 72,504 1 Elahn. (Cl. 131-7) outside on windy days which is not possible or practically" impossible with lighters and matches.

The lighting tip is added, during manufacture to crg arettes and broadly consist-s of a disc of ignition paperprovided with an ignition head, an anchoring pin preferably made of pressed tobacco and a suffering tube also: of pressed tobacco to facilitate ignition of the tobacco.

The main object of the invention is therefore the manufacture of a cigarette provided with a lighting head to enable smokers to light cigarettes outside on windy days.

Another important object of the invention is to assure a smoker of a smoke when in possession of a cigarette even though he may not be in possession of a match or lighter.

Still another important object is the elimination of the danger of carrying matches, which are sometimes forgotten in pants or coat pockets where they may be readily accessible to children.

Another important object is that the ignition tips can. be added to standard cigarettes.

With these and other objects which may appear as the description proceeds the invention consists in the novel arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown n the accompanying drawing forming part of this application and in which:

FIGURE 1, is a perspective view of a package of cigarettes showing the scratching surface for a cigarette provided with a lighting tip;

FIGURE 2, is a perspective View of a cigarette provided with a lighting tip as hereinafter more specifically described;

FIGURE 3, is an end view of a cigarette provided with an ignition disc and an ignition head; and

FIGURE 4, is a fragmentary side elevational view of a cigarette with the lighting tip in longitudinal section.

Referring more in detail to the drawing it will be seen' the invention comprises a cigarette box 19 provided with a scratching surface 11 made as hereinafter more specifically set forth. i

A cigarette as shown at 12 of conventional construction and size is provided with an ignition tip. The ignition tip consists of an ignition disc 13 immediately surrounded by a stilfening ring 14 of pressed tobacco is provided with an ignition head 17 to allow a cigarette to be struck at any angle. The ignition head 17 forms an integral part of an anchoring pin 18 preferably made 3,080,870 Patented Mar. 12, 1953 of pressed tobacco, although other suitable material could be used. The anchoring pin penetrates the ignition disc 13 and is secured in the tobacco beneath the disc.

The ignition paper consists of a sheet of paper not more than .005 inch thick coated on one side with a formula as hereinafter described in detail, and three additional sheets of porous paper with a thin coating of the said formula between each sheet of paper, the whole pressed down to a thickness of approx. .034 inch.

The ignition head 17 consists of a bulbous projection mounted on the extremity of the anchoring pin 18. In order to eliminate foreign taste, the anchoring pin is preferably made of pressed tobacco of the same brand as the cigarette.

When the ignition head 17 is rubbed against the scratching surface II it ignites and slowly burns the ignition paper, at the same time lighting the cigarette.

The formula used for making the scratching surface and ignition head is as presently used on safety matches now on the market.

Each sheet of paper forming the ignition disk is impregnated with a composition comprising 16 parts chlorate, 6 parts charcoal, 3 parts clay and 2 parts glue and after the composition is applied to the sheets, the sheets are pressed together to form a laminated disk.

It is believed the construction and advantages have been fully set forth and that further detailed description is not required.

While the preferred embodiment has been disclosed, it is to be understood that minor modifications may be resorted to without departing from the spirit of the invention and the scope of the claim.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows.

I claim:

A cigarette having a lighting tip disposed in the end thereof comprising a stiffening tube composed of pressed tobacco disposed in the end of the cigarette, said tube being adapted to contact the inner surface of the cigarette wrapper, the major portion of the tube being filled with tobacco and a disk formed of laminated sheets of paper, each of the sheets of the lamination being impregnated with a composition comprising chlorate, charcoal, clay and glue, said disk being embedded in the outermost portion of the tobacco filling the said tube and lying generally perpendicular to the axis of the cigarette, a portion of the disk extending beyond the general plane thereof to form a projecting surface adapted to contact an ignition producing surface.
