Improvements in Tobacco Pipes.
I, FREDERIC OWEN CHORLEY of 27 Greyfriars Road Reading in the County of
Berkshire Grocer do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide simple means for the removal of any
accumulation of nicotine or liquid within the stem of the pipe. The mouthpiece is
made with a projecting stem or spill which passes in through the stem of the pipe
and terminating in a small chamber situated beneath the bowl in which is placed
the tobacco. The bowl holding the tobacco communicates with the said chamber by
a small hole-which is so placed as not to be at the extreme end of the above-
mentioned projecting portion of the mouthpiece but a little way down its length
towards the mouth end of the pipe. In order that the smoke may pass from the
bowl to the stem of the pipe a slot is provided in the mouthpiece projection
communicating with the hole in the bowl and the chamber beneath it-so that the
smoke passes from the bowl through the hole and along the slot in the mouthpiece
projection into the chamber, and from thence into the stem of the pipe. In the lower
part of the above mentioned chamber is a hole or aperture communicating with the
outer air independently of the stem of the pipe. This aperture is closed by a screw
plug or other suitable device. It will be seen that any accumulation of liquid &c.
must take place within the aforesaid chamber, and in order to effectually remove such
accumulation the stopper ir removed from the aperture at the bottom of the
chamber, and the mouthpiece is turned round slightly so that the slot in the projecting
end of it escapes the hole leading from the bowl, thus closing communication between
the bowl and the chamber beneath; then by blowing down the stem all deposit
within the chamber is forced through the aperture at the bottom thereof, and so the
pipe may be cleared of any accumulation or obstruction without the necessity of
removing the mouthpiece as at present.
Further the pipe may be very effectually cleared without opening the aperture at
the bottom of the chamber or turning the mouthpiece as described, by simply blowing
down the stem out through the bowl, this empties the chamber by creating a vacuum
within the chamber and causing any liquid within it to pass with great rapidity out
through the bowl.
This latter mode may be advantageously resorted to when there is no tobacco in the
pipe; whilst the former mode is available when there is tobacco in the bowl and it is
desired to clean out the stem without removing the tobacco from the bowl.
As my invention is capable of some modifications without departing from the
general principle thereof I do not restrict myself to materials or dimensions, or to the
exact form or placement of the various parts.

COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
FREDERIC OWEN CHORLEY of 27 Greyfriars Road Reading in the County of
Berkshire England Grocer 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 supply a pipe of simple construction and so
formed that the moisture from the mouth of the smoker cannot have access to the

page_text: tobacco in the bowl, nor can the nicotine from the tobacco get into the mouthpiece
of the pipe.
My invention also consists of the means for expelling the moisture and nicotine
which may accumulate from time to time in a space or chamber provided within the
stem of the pipe.
دو
The principle upon which I base my invention is that of a "hit and miss connec-
tion to the bowl of the pipe and to a similar aperture arranged at the foot of the
pipe stem.
I effect this "hit and miss" arrangement by turning the mouthpiece of the pipe
upon its own axis within the stem of the pipe-by this means an opening which is
arranged near the end of the prolongation of the mouthpiece, can be placed in direct
communication with either the bowl of the pipe or the aperture or outlet before
mentioned.
It will be understood that only connection with one of these openings can be
obtained at the same time and that when one is open the other is closed.
While the pipe is being smoked the connection is made with the bowl of the
pipe, but should the pipe become foul the mouthpiece is turned so as to block
communication with the bowl, and open communication with the outlet, which latter
is fitted with a screw cap-now temporarily removed. It will be seen that by
blowing down the mouthpiece of the pipe under these circumstances I at once expel
from the interior of the stem any accumulated liquid or matter contained therein
without in any way disturbing the contents of the bowl. The screw cap is now
replaced to the outlet and the mouthpiece returned to its original position so as to
again establish communication with the bowl of the pipe when smoking is resumed.
The pipe can thus be cleaned without any risk of soiling the fingers and in a most
easy expeditious manner whilst the tobacco is still alight.
In order
The mouthpiece and the portion which projects inside the stem is made to fit easily
and tightly so as to form a good joint, but is capable of being wholly pulled out
from the stem in case it should be desired to thoroughly cleanse the same.
to lessen the risk of any accumulated matter passing into the mouth I fix in some
cases a short tube within the prolonged mouthpiece. And in another case I make
this tube as
a portion of a mouthpiece breaking the continuity of its interior
passage in the manner shewn in Figure 2 on the sheet of drawings hereunto
annexed.
I form and design the exterior of my mouthpiece and pipe stem in such a
manner that I can readily ascertain the exact position of the mouthpiece within
the stem necessary to establish the required communication whether with the bowl
or the outlet before described.
In order that my invention may be more fully understood I will now proceed
to describe the four figures upon the sheet of drawings hereunto annexed the
various parts of which are marked as near as possible with the like letters of
references to the like parts throughout. For the advantage of shewing my pipe to
a larger scale I have broken the mouthpiece of all figures.
Fig. 1 shews a longitudinal section through my improved pipe according to the
foregoing detailed description.
Fig. 2 is a modification shewing how my invention can be applied in a slightly
different manner, and
Figs. 3 and 4 indicate further modifications in the application of the principles of
my invention.
Figs. 2. 3 and 4 are also part longitudinal sections of the pipe.
In Figure 1, A is the mouthpiece, B the stem, and C the bowl of the pipe, D is the
prolonged portion of the mouthpiece bored at one side with the hole, E, which is
arranged to communicate with both the hole F in the bowl C and the outlet G
in the bottom of the pipe stem.
This prolonged portion D may be bored
communication through the holes F and G by
piece than when only one hole E is bored.
with two holes E which will enable
means of a shorter turn of the mouth-
The prolongation of the mouthpiece

page_text: which as before mentioned is marked D is bored out to as large a diameter as the
substance of the material will allow, and into the base is fitted as shewn a small tube
in the centre of the transverse section of the same, and which forms a continuation
of the hole bored through the mouthpiece. This inner tube I mark by letter H,
and although I prefer to use a tube of this description in a pipe made after the
style of the drawing Fig. 1, I may here remark that it is not in this instance an
essential feature. J is the cap to the outlet at the bottom of the pipes stem-the
bottom part of the bowl is suitably bored out to receive the prolonged mouthpiece
as shewn.
In Figure 2 it will be seen that the inner tube H₁ to a great extent takes the place
of the prolonged mouthpiece D in Figure 1, this tube His permanently fixed to the
mouthpiece A, but its opposite end is capable of revolving in the solid portion of the
pipe bowl when the mouthpiece is turned, thus a connection can be made or severed
with the bowl of the pipe whilst the communication to the outlet G is always open,
but this outlet is kept closed by means of the moveable screw cap J. The tube H' is
not bored continuously from end to end but only part ways from each end and
communication made to the interior of the hollow stem by means of transverse holes
bored into and at the ends of the longitudinal holes.
In Figure 3 a tube H" forms a continuation of the mouthpiece A having formed
at its extremity nearest the bowl a ransverse circular portion closely fitting the
internal perimeter of the stem B. In this last mentioned portion of the tube His
provided a hole which can be placed to coincide with another hole bored through the
stem B communicating with the bowl thus permitting the smoke to pass from the
bowl into the space within the stem B and thence by the transverse hole in the
tube H into the mouthpiece A. When it is desired to blow out any accumulation
within the stem the mouthpiece is slightly revolved so that the hole in the circular
extremity of the tube H¹ is moved away from the end of the passage communicating
with the bowl thus severing the connection between the bowl and the mouthpiece and
permitting accumulated liquid to be expelled through a hole or slot K in the lower
portion of the circular extremity of the tube H and thence out of the outlet. In
this form of my invention I have shewn a variation in the construction of the screw
cap J to the outlet G and it consists in prolonging the internal portion of the
screw cap which is bored from end to end so that when the cap is screwed up tight
its inner extremity fits closely against the solid portion of the pipe below the bowl
which effects the closing of the outlet G whilst the opening of the outlet can be
effected by a single turn of the screw cap by reason of the continuous hole which is
bored through its length- - or if desired for the more thorough cleansing of the
interior of the stem of the pipe the screw cap may be wholly removed as in the
before described figures.
As a further modification of the screw cap J, I may make after the manner of a
valve or top so that one half or quarter turn would open communication from the
outside of pipe to the inside of the stem and the reverse movement would close the
communication.
In Figure 4 a further modification of my invention is shewn and it consists in
forming the mouthpiece A so that a prolongation of it fits against an internal
shoulder of the stem B and is capable of being revolved so that communication
between the bowl and the mouthpiece may be cut off in the same manner as
described in the previously mentioned forms of my invention. A space or chamber
is formed in the mouthpiece and stem to receive accumulating liquid or matter,
which said space or chamber is situated beneath the hole connecting the bowl and
mouthpiece and communicates with the mouthpiece by means of a transverse hole
bored from the smoke conducting passage in the mouthpiece A to the said chamber
or space so that when it is desired to blow out the pipe the mouthpiece is slightly
revolved cutting off connection with the bowl, the screw cap J is removed as before
and the chamber can then be blown through.
As my improvements are capable of some further modifications without departing

page_text: from the principle thereof I do not restrict myself to materials or dimensions or to
the precise form or placement of the various parts thereof.
Having now particularly described and ascertained the nature of my said inven-
I declare that what 1 claim is.
