Improvements in Smoking Pipes.
I FREDERICK WILLIAM SCHROEDER of Newtown near Sydney in the Colony
of New South Wales Engineer 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 certain improvements in smoking pipes by which are
produced pipes for smoking tobacco which may be almost instantly thoroughly
cleansed of all fluid or other matter will provide a comfortable smoke and at the
same time be cheaply manufactured.
Smoking pipes constructed according to these improvements have a condensing
and deposit chamber in which fits a plug having one or more pistons thereon and
independent channels connecting the bowl orifice or channel and the chamber and
connecting the mouthpiece orifice or channel and said chamber and it is the
particular constructions and combinations together of said chamber said plug and
said channels which constitute the essence of these improvements.
But in order that this invention may be clearly understood reference will now
be made to the drawing herewith in which
Figures 1 and 2 are sectional elevation and sectional plan respectively of a
smoking pipe constructed according to these improvements while Figures 3, 4, 5,
and 6 are cross sections on lines a b c and d respectively of Figures 1 and 2.
Figure 7 is a sectional elevation or plan of a modified construction of such pipe
while Figure 8 is a cross section on line e of Figure 7 and Figure 9 and Figures 10
and 11 are sections of still further modifications.
The bowl A of the pipe is made as ordinarily of wood clay meerchaum or other
suitable material with orifice or channel A' and with bowl end A2 having suitable
connection to a chamber B of suitable material preferably impervious to moisture
and preferably such as vulcanite ebonite and the like. This chamber B as in
Figures 1, 2, and 7 may be an independent casing or tube fitting tightly on the
bowl end A2 and having the mouthpiece plug fitting within it or it may as
in Figures 9 10 and 11 be made integral with the mouthpiece D and fit over
the pistons of plug C which plug is in such case is fitted tightly in the bowl
end A².
The
In the pipe shown in Figures 1 to 6 the piston C¹ has around it a helical
channel C having connection by channels C² or by a space with the bowl orifice A¹
and by holes or channels C with the central passage C of the plug or stem.
piston C has a groove or hollow channel C connected by channel or passage C
with the central passage C³ of the plug and connected by port or nick or
opening C with the chamber B. The bowl orifice A' in addition to the connection
with the central passage C' by means of helical channel C³ and holes C may have
and preferably has connection C× through the piston head C¹ to said passage C³.
In use the smoke from bowl A is drawn through plug C into chamber B by way
of opening C and helical channel C³ and holes C the central channel or
passage C channel or passage C³ and port or nick C³. In this chamber B any
moisture or condensation is deposited and the smoke passes to the mouth by way
of inclined passage D' and central passage D2 and no excess moisture or saliva can
commingle with nicotine oil in such passages D¹ and D' as the nicotine oil cannot
pass out of chamber B.
In the modification shown in Figure 7 the stem C has piston heads C' and C'
forming the ends of the condensation and deposit chamber B and the casing of said

page_text: chamber B has in it a through passage B' from end to end the bowl end of which
communicates with space C* and the mouth end with groove or hollow C' which
latter is connected by port or nick or opening C' with chamber B. The smoke
travels from bowl A through orifice or channel A' and space Cx
hollow C' and port C' to chamber B and thence through passages D₁ and D² to
passage
the mouth.
B¹
In the modification shown in Figure 9 the stem C is permanently fixed in
orifice A¹ and it has upon it piston_heads C1 and C on which the chamber casing
which forms part of mouthpiece D just fits. The smoke passes into central
passage C5 which abuts on orifice A and terminates in chamber B from whence
through passage D¹ and space D³ it finds its way through channel D² to the
mouth.
In the modification shown in Figures 10 and 11 the stem C is fixed in the
crifice A¹ and the casing of chamber B (being part of the mouthpiece D) fits over
the piston heads C and C thereon. The central passage C abuts on orifice A'
and terminates in groove or hollow C' with connecting port or opening C° to
chamber B which said chamber connects by way of channel D' and space D³ to
channel D² of mouthpiece D.
It will be seen that the mouthpiece D is either held by piston heads in
chamber B or it is held on such piston heads and forms chamber B. To thoroughly
clear the pipe of all extraneous matter it is only necessary to withdraw the piston
heads from the chamber by a very slight action when the piston heads will remove
from the chamber every particle of solid or fluid. If both of the separated parts
be slightly jerked or shaken and then put together again the pipe will be as sweet
and pure or practically so as a new pipe.
In these makes of pipes and especially in those shown in Figures 9 and 10
and 11 there is no or but very little opportunity of the material of the pipe or
bowl becoming impregnated with nicotine oil as the stem and the mouthpiece are
as before stated constructed preferable of impervious material. The mouthpieces
of the pipes shown in Figures 9 and 10 and 11 too are useful as cigarholders if
so desired.
Having now particularly described and explained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. In smoking pipes the combination and arrangement with the bowl of a
condensing and deposit chamber formed around a plug having piston heads thereon
and having independent connections with the bowl orifice and with the mouthpiece
orifice in the manner and for the purposes herein described and explained and as
illustrated in the drawings.
Second. The particular construction of smoking pipe having condensing chamber
removable plug and channels or passages substantially as herein described and
explained and as illustrated in Figures 1 to 6 of the drawings.
Third. The modified constructions of smoking pipe substantially as herein
described and explained and as illustrated respectively in Figure 7 in Figure 9 and
in Figures 10 and 11 of the drawings.
