An Improvement or Improvements in Tobacco Pipes.
I, HARVEY ALLCOCK, of No. 67 Francis Road Edgbaston, Birmingham in the
County of Warwick Fishing Tackle Manufacturer do hereby declare the nature
of this invention to be as follows:-
My invention consists of the improvement or improvements hereinafter described
on an invention for which Letters Patent were granted to me dated January 26, 1893
No. 1753.
In order that my present invention may be the better understood I remark that
the said patented invention consists essentially in coating the interior of the bowl
of the pipe together with the bore and joints where there are any joints with finely
powdered charcoal applied by being mixed with vinegar and isinglass or other kind
of gelatine and applied by means of a brush; the mixture being allowed to dry by
spontaneous evaporation. The charcoal lining in the pipe retards or diminishes
the fouling of the pipe and the gaseous matter inhaled by the smoker is deprived
of the unpleasant flavour attendant on the use of ordinary pipes.
As the result of large experience with pipes made according to my patented
invention I have found that the occasional detaching of particles of the charcoal
from the lower part of the bowl and from that part of the pipe at which the stem
joins the bowl sometimes occasions inconvenience to the smoker and the object of
my present invention is to obviate this inconvenience.
In treating pipes according to my present invention I employ a composition
consisting of finely powdered charcoal, vinegar and isinglass or gelatine the said
composition being of the consistency of paint. I apply the said composition by
means of a brush to the interior of the bowl only of the pipe taking care not to
apply the composition to the lower part of the bowl that is the part where the bore
of the stem opens into the bowl. By thus restricting the charcoal lining to the
bowl and leaving the extreme lower part of the bowl uncoated the detaching of
particles of charcoal is prevented without diminution of the beneficial effects
attending the use of charcoal herein before referred to.
Dated this Tenth day of April 1896.

An Improvement or Improvements in Tobacco Pipes.
I HARVEY ALLCOCK, of No. 67 Francis Road, Edghaston, Birmingham, in the
County of Warwick, Fishing Tackle Manufacturer, do hereby declare the nature
of my invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention consists of the improvement or improvements hereinafter described
on an invention for which Letters Patent were granted-to-me dated January 26 1893,
No. 1753

page_text: In order that my present invention may be the better understood I remark that
the said patented invention consists essentially in coating the interior of the bowl
of the pipe together with the bore and joints, where there are any joints, with
finely powdered charcoal applied by being mixed with vinegar and singlass or
other kind of gelatine and applied by means of a brush; the mixture being allowed
to dry by spontaneous evaporation. The charcoal lining in the pipe retards or
diminishes the fouling of the pipe and the gaseous matter inhaled by the smoker
is deprived of the unpleasant flavour attendant on the use of ordinary pipes.
As the result of large experience with pipes made according to my patented
invention I have found that the occasional detaching of particles of the charcoal
from the lower part of the bowl and from that part of the pipe at which the stem
joins the bowl sometimes occasions inconvenience to the smoker and the object of
my present invention is to obviate this inconvenience.
In treating pipes according to my present invention I employ a composition
consisting of finely powdered charcoal, vinegar and isinglass or gelatine the said
composition being of the consistency of paint. I apply the said composition by
means of a brush to the interior of the bowl only of the pipe taking care not to
apply the composition to the lower part of the bowl, that is, the part where the
bore of the stem opens into the bowl. By thus restricting the charcoal lining to
the bowl and leaving the extreme lower part of the bowl uncoated, the detaching
of particles of charcoal is prevented without diminution of the beneficial effects
attending the use of charcoal hereinbefore referred to.
Figure 1 of the accompanying drawing represents partly in elevation and partly
in section a tobacco pipe the bowl of which is lined with charcoal according to my
present invention and Figure 2 represents the same in plan.
It will be seen by an examination of the said drawing that the charcoal lining a
of the bowl b extends to near the bottom of the said bowl, the said bottom, that is,
the space c around the part where the bore of the stem opens into the bowl, being
left uncoated with the charcoal composition or mixture so that there is little ris
of any detached pieces of charcoal powder being drawn through the stem into the
smoker's mouth which occurs in the use of ordinary charcoal lined pipes to the
smoker's discomfort and annoyance.
Pipes of the kind hereinbefore described and illustrated possess all the beneficial
effects of charcoal lined pipes without the objection attending the use of ordinary
charcoal lined pipes hereinbefore referred to.
Although I have described my invention only in connection with tobacco pipes
the bowls of which are coated with the composition or charcoal mixture herein-
before described yet wish it to be understood that my improvements are
applicable to tobacco pipes the bowls of which are coated with other compositions
or mixtures consisting essentially of charcoal.
My improvement or improvements are applicable to all charcoal lined tobacco
pipes such for example as charcoal lined clay pipes charcoal lined wooden pipes
and the like.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that I claim as
my invention of "An improvement or improvements in tobacco pipes
In tobacco pipes having charcoal lined bowls, leaving the bottom of the bowl,
that is, that part of the bowl into which the bore of the stem opens, uncoated with
the charcoal composition or mixture substantially as herein before described and
illustrated in the accompanying drawing.
Dated the Thirteenth day of May 1896.
