I CORBET JOHN COVENTRY, of the Naval and Military Club, Piccadilly, in the
County of Middlesex, Gentleman, do hereby declare the nature of this invention to be
as follows:-
The bowl of the pipe is constructed in the usual manner with a hole, or perforation
at the bottom in line with the stem.
Into this hole or perforation is placed a solid tube of metal or other material with
two or more slots cut therein. When the stem or mouthpice is screwed onto the
bowl of the pipe it pushes the perforated tube into the hole in the front part of the
bowl and renders it air tight.
When it is necessary to let out the nicotine or other accumolations, by partially
unscrewing the stem it releases the perforated tube and allows the nicotine to escape.
Dated this 29th day of July 1887.

Improvements in Pipes for Smoking Tobacco.
I CORBET JOHN COVENTRY, of the Naval and Military Club, Piccadilly, in the
County of Middlesex, Gentleman, 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 object of this Invention is to enable the smoker to get rid of the fluid and 5
nicotine and for this purpose the bowl of the pipe is constructed in the usual manner,
with a hole or perforation at the bottom leading into the stem. The passage through
the main portion of the stem is enlarged and so as to form a chamber for the collection
of the fluid and nicotine and a small opening leading to the outside of the bowl is
formed in the end of the chamber which hole when the pipe is in use is closed by
means of the solid conical end of a tube of bone or other material which is connected
with the mouthpiece.
The Invention will be readily understood on reference to the accompanying sheet
of drawings, Fig. 1 of which represents a pipe constructed according to my Inven-
tion and Fig. 2 a plan of the mouthpiece. Fig. 3 a modification thereof. A is the
bowl of the pipe and B the hollow stem communicating with the bowl by means of the
perforation a and also with the outside of the bowl by means of the perforation b.
C is the mouthpiece which is threaded at c for the purpose of enabling it to be
screwed into the stem. D is a tube of bone or other suitable material which is formed
with a conical solid end d and with a slot d¹ to admit the smoke to the interior of the
tube. By screwing the mouthpiece far enough into the stem the conical end of the
plug is forced into the perforation b and closes the same so that when in use no air
can enter the stem except through the perforation a.
The fluid nicotine formed whilst the pipe is in use lodges in the chamber surround-
ing the tube D-and to get rid of the same the smoker unscrews the mouthpiece thereby
withdrawing the plug d from the perforation b and this latter being free the fluid and
nicotine can be ejected by blowing down the mouthpiece or simply holding the pipe
so that the fluid and nicotine can escape.
Fig. 3 is a modification of my Invention wherein the outlet b is made at the bottom
of the pipe the action being the same as that described for Figs. 1 and 2.
Fig. 4 is a modified form of construction of the mouthpiece.
The part 1. 1. is made with a screw thread 2 to take into the stem, the piece 3 being
removable at will. The part 1. 1 is made with places 4 for the thumb and finger for
unscrewing.

page_text: The object of this construction is to adjust the mouthpiece into any position so
that if the thread of the screw becomes worn, the mouthpiece shall not be out of
position.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, I would have it
understood that I claim :-
1. In a pipe such as described, the chamber for collecting fluid and nicotine formed
in the stem B, the perforation b and the tube D having a conical solid end d for closing
the said perforation, substantially as described and illustrated in Figs. 1, 2, 3 and 4 of
the accompanying drawings.
