2 Claims. (Cl. 131-12)
The invention relates in general to a smoking
pipe of the multi-chambered stem type and the
invention .speci?cally relates to an improvement
in “the stem element or stem inserts which de?ne

invention ‘relates to that type of pipe stem which
is rprovidedadjacent the bowl with a chamber for
receiving smoke from the bowl and incidentally
tr'ap ‘therefrom the oily and tarry tobacco con
10 densate juices, hereinafter referred to as the oil
trap or condensing chamber, and from which
chamber smoke is vdrawn into a smoke cooling
chamber in or adjacent the bit end of the stem
and wherein the smoke is permitted to circulate

charged any saliva or mouth moisture from the

will be more fully set forth in the following par
ticular description of one form of pipe embody
ing the invention, and the invention also» consists
in certain new and novel features of construc 5
tion and combination of parts hereinafter set
forth and claimed.
The accompanying drawing is a view in vertical
axial section through a tobacco pipe illustrating
a preferred embodiment of the invention.
Referring to the drawing, there is disclosed
a tobacco bowl Ill provided with a tobacco cham
ber I I and an integrally extending neck 12 form
ing the inner end of a stem [3, the outer end of
which stem is formed by means of a bit M.
bit is provided with a plug end l5 forming a tenon
telescoping in the open end of the neck l2 to form
a two section stem.
The neck is provided with a bore extending
therethrough which comprises an enlarged outer
“sweet” while in use; which can be easily cleaned;
cylindrical portion l‘l terminating at its inner
and particularly from which the trappedjuices,

the mouth of the user, may be readily and quickly

and opening into the bottom of the tobacco

"The1present disclosure particularly features the
formingof the stem in sectional parts which may
be readily separated from eachother and when
separated provide exposed, easily cleaned surfaces
30 which can be scoured with the ordinary pipe
‘Smoking ‘pipes as now generally constructed
become objectionable largely because the briar
wood-of which they are usually constructed read
35 ily absorbs the oily and tarry tobacco condensate
and give rise ‘to what is commonly referred to as.
a strong pipe. It has been suggested heretofore
to line the condensing chamber of such pipes with
some form of metal liner and which, of course,
40 acts to prevent the contamination of the wood,
but as heretofore constructed, these metal lined
chambers have been designed to permit the smoke
to pass therefrom but have not been provided
with any means to facilitate the cleaning of the
same whenever it is desired to discharge the pipe
of its accumulated juices.
Accordingly, another object of the invention is
to provide as part of the stem insert, a combined
funnel and pouring nozzle which will permit and
' , facilitate the emptying of oils from the condens
ing chamber whenever the outer end section
forming the bit end of the stem is removed for
this purpose.
Various other objects and advantages of the
55 invention will be in part obvious from an inspec
Referring to the bit l4, it is provided with a
bore 2| of relatively small diameter projecting in
wardly from which is a tube 22 forming an ex
tension of the‘ bore 2! and projecting towards
the bowl end beyond an inner wall 23. The in 30
ner end‘ of the bit is counterbored to provide a
smoke cooling chamber 24 largely contained in
the bit and into which protrudes axially the in
ner end of the tube 22. ' It is understood that the
structure as thus far described is somewhat con
ventional and is illustrated herein to show the
adaptability of the novel features of the dis
closure to a known form of pipe.v
' _
The drawing discloses a metallic construction
25 ?tted in the neck boreand comprising a thin
walled sleeve 26 wide open at its outer end and
provided with a wall 21 at the opposite end. A
small- diametered tube 28 extends through the
wall 21, projects into and outlines, or at least
partially outlines.the constricted portion IQ of
the bore and leads to the bottom of the tobacco
chamber H. The tube also projects to the right
of the drawing a material distance beyond the
wall 21 into the oil trap or condensing chamber
29 outlined by the sleeve 26.
‘ The open end of the sleeve is closed by means
of aplug like partition ,‘30 of a readily removable
unit 3|, preferably formed of aluminum or :Bake‘
lite. The partition 30 forms the right end of
the condensing chamber 29 and the left end clo
sure of the smoke cooling chamber 24. The unit
3| includes a long tube 32 projecting integrally
from the partition 30 and. extending therefrom
a material distance into the cooling chamber in
Cl axial alignment with and spaced slightly from
the tube 22 carried by the bit. This long tube
is designed to constitute a pouring nozzle or
drain for discharging the condensing chamber
of its oil or other ?uid content when the bit is
10 removed from the balance of the stem for this
purpose. The tube 32 is of su?icient length to
extend a material distance into the cooling cham
her and thus provide an annular saliva drip re
ceptacle 33, particularly designed for wet smok
The long tube provides a ?nger piece or
handle by means of which the unit as a whole
may be withdrawn from the sleeve and for the
purpose of facilitating the ?nger engagement the
outer end of the tube is provided with a bulbular
20 enlargement 34 to prevent the ?nger slipping off i
the end of the tube.
The side of the partition 30 facing the condens
ing chamber is provided with a conical funnel
like surface 35 designed to receive drip which
may hug the inner wall of the sleeve 26 and dis
charge the same through the bore 36 of the pour
ing nozzle 32. The bore 36 should have a con
ducting capacity not only sufficient to convey
the smoke therethrough in the normal operation‘
of the pipe but should also have capacity suf?
cient to permit the flowing therethrough of the
heavy liquid parts of the tobacco condensate. It
is not intended in this structure that the heavy
tars which settle in the condensing chamber be
poured therefrom through the bore 36.
tars are best removed from time to time by with
drawing the unit from the sleeve and cleaning
its inner surface with some rugged form of
cleaning device or pipe cleaner. However, the
lighter liquids can be more frequently discharged
from the condensing chamber simply by remov
ing the bit l4 which thus exposes the pouring
nozzle and by merely tipping the shank or stem
of the pipe downward the more flowable portions
45 of the condensates may be quickly ejected; the
bit restored in place and thus the pipe is cleaned
to this extent and ready for renewed operation.
The metal parts and preferably the chamber
lining shell 26 are preferably made of an alumi
num alloy which functions to quickly dissipate
heat from the bowl end of the stem. Oils and
tars taken out of the smoke in the condensing
chamber are prevented from entering the‘bowl
and wetting the tobacco; therefore the tobacco
55 may be smoked to the bottom of the bowl with
nothing left but ash. However, the construc
tion is designed so that if the smoker drools saliva
while smoking it will be trapped in the chamber
33 at the lower end of the smoke cooling cham-v
60 ber in the event that the smoker habitually
smokes with the bowl downward at a lower level
than the bit or into the right end of the cooling
chamber about the area into which the tube 22
protrudes in the event that the smoker habitually
66 smokes with the bowl elevated.
While there have been shown, described and
pointed out in the annexed claims, certain novel
features of the invention, it will be understood
that various omissions, substitutions and changes
in the form and details of the device illustrated
and in its operation may be made by those skilled
in the art without departing from the spirit of
the invention.
