1 HARVEY ALLCOCK of 31 Hagley Road Birmingham in the County of Warwick
Fish Hook Manufacturer do hereby declare the nature of my said invention to be as
follows:
My invention has for its object improvements in tobacco pipes which are intended
to protect the smoker against the transfer of impurities. In carrying out this
invention:-
I use steel wire of best prepared make and I coil this wire round a spit or mandril
in long lengths and then cut to the lengths required. I then stove these coiled
springs in a similar manner to the stoving of fish hooks until they are sufficiently
heated. I then throw the springs into water to harden them. I then temper them
in sand after which they are scoured and polished. They are then warmed and put
into cement from concentrated gums. The are then shook up in a culinder to throw
off any superflous cement. While they are in a heated state I throw them into
charcoal dust and there let them lie for say about forty-eight hours or so. They are
then shook up in a bag to liberate them from any superflous dust.
They are then ready to apply to tobacco pipes.
In applying these specially prepared springs to tobacco pipes the length and size
will vary according to the design of the pipe. For instance in the case of the well
known pipe "Free and Easy" 1 fit the spring into the chamber formed at the
junction between the stem and the bowl. And in the case of clay or other pipes not
having this chamber I make the spring of a suitable size to push into the smoke
passage leading from the bowl. It is well known that both the metal and charcoal
possess valuable medical qualities and they entirely act as a preventative against
poison or contagion being transferred to the smoker in fact it acts as a disinfectant
to the pipe.

page_text: Improvements in Tobacco Pipes.
I, HARVEY ALLCOCK of 31 Hagley Road Birmingham in the County of Warwick
Fish Hook Manufacturer do hereby declare the nature of my said invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
My invention has for its object improvements in tobacco pipes which are intended
to protect the smoker against the transfer of impurities by the utilization of specially
prepared metal and charcoal which possess valuable medical qualities and entirely acts
as a preventitive against poison or contagion being transferred to the smoker in fact
it acts as a disinfectant to the pipe,
In order that my invention may be clearly understood and more easily carried into
practice I have appended hereunto a sheet of drawings upon which is illustrated a
pipe and cigarette holder with my invention applied thereto.
Figure 1 is a longitudinal section through a pipe shewing the coil A in elevation.
Figure 2 is a longitudinal section through the stem of an ordinary clay or wooden
pipe.
Figure 3 is a view of one end of the coil A shewing how the end of the wire is
tucked in.
Figure 4 is a longitudinal section through a cigarette holder.
Figure 5 is an elevation of the mouth end of same.
1 insert in a convenient position in the stem or mouth-piece of the pipe B the coil
of hard drawn charcoal iron wire, which has been twisted on a mandril and cut to the
required length after which the ends of the wire are tucked inside under the first bar
of the coil as shewn by a Figure 3 which allows the coils to be placed in and with-
drawn from the pipe without friction. Before being ready for use they are subjected
to the process of being bunched up together and retorted or gassed with say
cherry-wood and shaken up in a muffler and afterwards put into a basin of cement
consisting of say isinglass and acetic acid then placed in a temporary pan filled with
charcoal dust the dust being well worked in with a tempering knife which requires to
be done by an experienced workman each coil of the wire being arranged to ½ of
an inch apart so as to allow the dust to freely intermix, they are then shaken up in a
warned mutter or bag to liberate the superfluous dust and left to dry being then
ready to place in the pipe B as shewn by Figure 1.
In the case of ordinary clay or wood pipes having thin stems as shewn by C
Figure 2 a coil of much smaller diameter is placed within.
The coil for the cigarette holders is treated in a similar manner to those for the
pipes but while warm with the cement on they are rolled round with the paper a³
which adheres to them forming a stiff cover for any ornamental cover that may then
be put on. They are pinched oval at the mouth end as shewn by Figures 4 and 5.

page_text: The coils must be kept clear central so as to allow of a direct draught and may be
placed in any convenient part of the pipe through which the smoke is drawn.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In improvements in tobacco pipes the specially prepared coil placed within the pipe
in such a manner that the smoke must be drawn through it to the mouth substantially
as and for the purpose herein set forth and shewn upon the drawings.
