Improvements in or relating to Tobacco Pipes, Cigar Holders,
I, ANGELO LEBORO, of 9
and the like.
and 11, Moor Lane, Fore Street, in the City of.
London, 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 :-
This invention relates to tobacco pipes, cigar holders and the like, the object
being to neutralize the injurious effects of the nicotine, and will be best understood
by reference to the accompanying drawings, in which
Figure 1 is a longitudinal section of a pipe constructed to carry out my
invention, and
Figures 2 and 3 are elevations of the mouth-piece and bowl of the said pipe
separated from each other.
Fig. 4 is a longitudinal section of the mouthpiece & stem of a pendant pipe.
Figure 5 is a longitudinal section of a cigar or cigarette holder constructed to
carry out my invention, which in
Figures 6 and 7 is shown in elevation in a disjointed condition, . Figure 6
representing the mouth-piece and Figure 7 the body of the holder.
Figure 8 is an elevation of a piece of absorbent material preferably sponge
employed in the carrying out of my invention.
Like letters represent like parts throughout the drawings.
The pipe shown in Figures 1, 2 and 3 is constructed of a mouth-piece A. and
bowl B, the latter having a stem B' the passage B2 of which is enlarged at B³ to
form a chamber hereinafter referred to by the letter B³. C is a preferably silver
tube advantageously secured to the mouth-piece A by a screwed connector D D
the part D screwing into the mouth-piece and the part D' fitting tightly into the
open end of the chamber B³. E, see also Figure 8, is a piece of absorbent material
preferably sponge cut advantageously to a cylindrical form so as to fit nicely into
the tube C.
The sponge E before being placed in the tube C is thoroughly impregnated with
a solution of salicylic acid say 60 per cent. of the acid to 40 per cent. of cold water.
The sponge is soaked in this for preferably not less than twelve hours and is
afterwards dried in the air, on say a horse-hair or silk sieve.
When the pipe is used the sponge which has been previously thoroughly dried
absorbs all the nicotine, the smoke reaching the smoker's mouth being purified very
cool and agreeable. The sponge when considered to have absorbed as much
nicotine as is advisable, may be removed and a new dry sponge prepared as before
described put in its place.
In Figures 4, 5, 6 and 7 the device is constructed substantially in the same
manner as before described, the only difference being that in these examples the
parts D'of the connectors D D' are screw-threaded and screw into the open ends of
the chambers B³ although the form of connector shown in Figure 1 may be
employed also in these cases and vice versa.
Although I have herein mentioned only the use of salicylic acid for the purpose
of neutralizing the injurious effects of the nicotine, I wish it to be understood that
any other agent having similar properties may be employed, although up to the
present salicylic acid has been found to give the most satisfactory results,

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a tobacco pipe cigar holder or the like the employment of salicylic acid for
neutralizing the nicotine."
2. In a tobacco pipe cigar holder or the like the employment of a sponge treated
with salicylic acid for intercepting and neutralizing the nicotine substantially as
described.
3. In a tobacco pipe cigar holder or the like the employment of a sponge treated
with salicylic acid or other agent for intercepting and neutralizing the nicotine
substantially as described.
4. The combination with a tobacco pipe cigar holder or the like of a tube such
as C and sponge such as E the latter treated with salicylic acid substantially as
and for the purpose described and illustrated in the accompanying drawings.
