COMPLETE SPECIFICATION.
A Tobacco Smoking Mixture.
I, HENRY BINGHAM, of Freshfield, near Liverpool, in the County of Lancaster,
Commission Agent, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
The tobacco smoking mixture according to this invention consists of tobacco mixed
with asbestos in suitable proportions such mixture being applicable for use in or for
manufactured tobaccos, cigarettes, cigars, or in any other form: or, in lieu of asbestos,
any other analogous non-combustible material, or equivalent fibre, such as herein
specified, may be employed.
This invention has mainly for its object the manufacture or production of tobacco
smoking mixture, in which the last portion of a charge of tobacco of a pipe-full, or
the end of a cigar, or cigarette, shall not become wet or charged with moisture, as
usually occurs. That is to say, when ordinary cut tobacco is smoked in a pipe, or a
cigar or cigarette is smoked, the last portion of the tobacco, or the end of the cigar or
cigarette, as the case may be, usually is found to be charged with moisture--including
nicotine, and is not so agreeable to smoke; and it acts, moreover, in consequence,
detrimentally upon the system and health. The end sought to attain by this
invention is to render this last portion of a pipe of tobacco, cigar, or cigarette,
barmless, or as agreeable to the smoker as the first and main portion thereof. By
this invention, also, the combustion of "wet" tobacco (manufactured) and cigars, in
smoking, is rendered generally more free and regular, ihan ordinary "wet" tobacco
or cigars.
To this end, I mix, as above stated, with the tobacco, a certain proportion of asbestos
fibre; or, in lieu of asbestos, any other analogous non-combustible material, or
equivalent fibre, such as silica fibre, or silicated fibre, or the like, may be used.
A suitable and sufficient proportion of asbestos fibre (when this fibre is used), I have
found to be from a half to two per cent., by weight, of the tobacco; but in tobacco of
a lighter, or stronger, or drier, or wetter kind, respectively, a less, or greater
proportion of the fibre or material may be used. Or other proportions than these may
be used, as may be considered desirable.
In manufacturing the mixture for smoking in pipes or cigarettes, I, according to
one method, take two, three, four, or more tobacco leaves, and arrange them one upon
another, and then lay upon them a layer of the fibre or material, and repeat these
alternate layers of tobacco leaf and fibre or material, until a sufficient quantity is
piled up this pile may be then wrapped in another leaf or leaves. I then subject the
Price 4d l

page_text: pile to pressure in a suitable press, and for such a length of time, until the whole is
pressed into a cake. This cake, thus made, is then ready to be cut up into ordinary
smoking tobacco or mixture, and when so cut and spread or mixed, the asbestos or
other material becomes invisible.
A modification of this method of manufacturing, consists in damping or wetting
the leaves and fibre or material before, or during the making of the pile; the result of
which is that the fibre becomes stained the same colour as the tobacco, and is invisible
before it is cut and spread, or mixed. If, however, the tobacco leaves are not very
dry, the natural moisture of the leaves stains the fibre or material to the colour of
themselves when under pressure, and hence the wetting process is not required.
Another method of combining the tobacco and asbestos or other material
consists in sprinkling or spreading it loosely amongst the tobacco leaves, and manufac-
turing such mixture in the manner above described, or in the ordinary, or any other
suitable mode of manufacturing.
In applying the invention to the manufacture of cigars from tobacco leaf, the
asbestos or other material is sprinkled, or laid, or otherwise distributed, amongst the
leaves prior to being rolled up and formed into their usual shape; the percentage
of tobacco and asbestos material being preferably about the same as above specified.
Having thus described fully and clearly the nature, object, and effects of this
invention, I wish it to be understood, that it is not confined to any particular methods
for carrying out the combination of the tobacco and asbestos or other material,
although the methods above set out 1 have found to be convenient for effecting the
object and purposes of the invention; but what I claim as this invention is :―
The manufacture of smoking mixture herein described, that is to say, a mixture
consisting of tobacco and asbestos or other equivalent or analogous material mixed
together for the purposes set forth.
