SMOKING PIPE
John P. Tai-box, Philadelphia, Pa.
Application March 1, 1934, Serial No. 713,558
18 Claims. (Cl. 131-12)
My invention relates to smoking pipes and
method of cleansing the same. Such pipes are
commonly intended for use in connection with
loose tobacco. A special class of such pipes,
5 however, has to do with cigar and cigarette'hold
ers or otherutilization of tobacco in wrappings
or containers. My invention may be applied to
any of these.
Its outstanding object is the eflicient collec
10 tion of moisture and other content of the smoke
which usually collects within the stems of pipes
and the eiìicient cleansing of the stem of such
products.
A further object is the guarding of the stem
15 with a cleansing device against the entry of solid
mattei' from the pipe charge and the eiiicient
ejection of the charge residue and eñìcient
cleansing of the pipe bowl. The latter two re
sults aid materially in guarding the draft mem
bers of the pipe against entry of solid matter
from the charge.
A yet further object is to maintain open and
free from deposit which may obstruct the draft,

'I'he utilization of a pressure force pump for
the ejection of the liquid condensate and ash or
other solid content of the smoke which is col
lected by condensation usually in the stem, is
the means best known to me at the present time
for carrying out the method of my invention
which is simply this. A ñuid pressure is de
veloped within the liquid content of the pipe
50 and this iiuid pressure is utilized to eject the
contents themselves.

In the forms of the invention shown in Figs.

smaller than the over-all diameter of the stem

of the parts is shown also in Fig. 9. The initial
movement of the piston I5 from the position of
Fig. 1 closes the port 22 communicating with the
mouthpiece II so that the only possible egress
for the contents of the chamber I4 is axially of
its length and forcibly through the port I8. But
one movement of the plunger completely and
thoroughly cleanses the entire chamber. In all
the formsl of the invention, the close approach 4.3

that portion of the stem I2 connected with the
bowl I8 and continuing axially of the stem
stem per se in its entirety.
Referring now particularly to each of the sev
eral forms of the invention in succession, in the
form of Fig. 1, the plunger I5 is of the piston type
and normally lies at the mouthpiece end of a
pipe. Here the piston I5 is bridged normally by
a» draft connection 22. between the chamber I4
and the stem II. This draft connection is in
the form of a slot cut in the end oi the tube 28 at
its top. It establishes draft connection around
60 the piston I5 between the chamber I4 and the
draft opening 23 of the mouthpiece. 'I‘he piston
rod I6 is extended out through the head I9 clos
ing the opposite end of the chamber I4 and
provided with a small suspended ring 24 for
manual reciprocation of the piston I5. The
mouthpiece II is threaded on to the adjoining
end of the tube 20 to such an extent that it en
tirely closes the slot 22. A small screw or rivet
25 insures proper angular relation of the mouth
70 piece to the tube 28. The abutment of shoulder
26 against the end 21 of the tube may serve a
similar and perhaps cooperative purpose.
The
outer walls of the stem may be constituted of
tubular filler members as 21’ between the root
75 of the stem 28 integral with the bowl I0 and the
a strong fluid pressure, and it is through this ,pressure and, in the form shown in Figs. 2 and
4, additionally through the sudden outward
thrust of the movable abutment I9' by the in
cline on the piston, that the forcible ejection is
achieved. Immediately the plunger may be re- .
turned to the normal position of Fig. l and the
mouthpiece II and attached tube 20 turned back
through 180° closing port I8 and again opening
the port I1 to the bowl.
The cleaned pipe is
again ready for smoking.
During this smoking the guard disc 29 ef
fectually guards port I'I against the entrance of
solid matter.
Such small grain solid matter as
may once in a great while pass the disc screen
29 is eifectually cut off and cut through by the
edges of the tube wall 28 at the port I1 when the
tube 28 is rotated to open port I8. The turning
of the edges at port I1 to the opening of the
port I8 presents any such small solid matter
at a point where the forcible ejection of the
contents of the chamber I4 when plunger I5
brings up against the head I9 causes a‘so the
forcible ejection of such occasional solid matter.
However, during the great part of the time the
disc 29 precludes the solid matter from reaching

This is aided very greatly by the
180° recess in the bottom of the bowl as is shown
functioning of the disc 29 when it is moved
axially of the bowl in ejeoting residues of
in Fig. 12 whereas in the form of Figs. 1 and 2 the
arrangement is the reverse with the stop 33 on the

in Fig. 11. In the form of Fig. 4 the outer wall of

or’ the disc 29 residue from the bowl I0. This
keeps the bowl so thoroughly cleansed of minor
particles of tobaccol and ash and particularly
burned tobacco that such material does not ac
cumulate at the bottom and therefore is not
present to pass by the disc 29. Yet further, be
cause the disc is used the residue of charges is
ejected as a body and there is no call for the use
brought about by a relative movement oi“ the parts

tion of the form of Fig. 4 is precisely the same as
that of the form of Fig. 10.
The bowl of this form of Fig. 4 is also diñerent
from the bowl of the form of Figs. l and 2. It is a
actually project residue into the port I'I. Fur

notches 32 in its edge and not in the form of per
replacement of this shell 36 from the ribs of the '.

the draft from the bowl to the edges of the disc bowl. The shell thus jointly serves as a manipu
guard 29. This gives a better distribution of the lator of the guard 29 and an insulator of the metal
of the pipe. The tubular stem I 2 may or may not

The displacement pump of Figs. 2, 3 and 4 is of
a different form. The piston I5 and the plunger
IB’ are of a diameter completely ñlling and fitting
the tube 20, see Figs. 2 and 3, or the bore of the
complemental taper 3l between the bottom of the
stem per se, see Fig. 4. The chamber I4 is formed

the bowl may be moved axially toward the mouth

or the port 22’ oi Fig. 4 formed in the stem per se line position Vshown in Fig. 6, the stem is consti
to the port I‘I. The head I9' is in the form of a
spring the one end of which is riveted or other
wise iixed to the tube 20 (Fig. 2) or to the bottom
of the bowl (Fig. 4) and the other end of which
tuted an ejector for the residue contents of the
bowl. To this end the disc guard 29 is mounted
directly on the end of the stem and secured there
to by small screws 38 or equivalent means.
In
projects yieldably into and closely fits the rectan
lgeneral plan form the disc guard 29 is of peri
gular cross section of the chamber I4 as shown in I
metric outline shown in Fig. 5 and has a similar
relation to the interior walls of the bowl I0. The
bowl II) is provided with an upturned lip 39 ex
tending the lower edge of the mouth 4D beyond
ythe upper edge whereby ash may not be readily
dropped from the open end of the bowl during the
Figs. 2 and 3.
In the form of Figs. 2 and 3. therefore, when
the mouthpiece I I and connected tube 2|) are
turned to close port I'I and open port I9. and
thereafter the plunger I6' is pulled out as shown
in Fig. 10, the head of the chamber constituted by
the spring I9' not only serves as a compression
head but scrapes the entire chamber I4 clear of
its contents and iinally rides up on to the opposite
end of the rod, which constitutes the piston I5,
forcibly ejecting the contents through the port I8.
The operation otherwise is essentially the same
as that in Fig. 1. In this form oí the device like
that of Figs. l and 4 the rotation through 180° to
close port I'I and open port I8 and vice versa is
TI) regulated by a stop 33 which is fixed to the wall
of the bowl I0 and projects into a 180° recess in
the end of the tube 20 or the end of the plunger I6'
as the case may be. See Figs. 11 and 12.
In the form of Fig. 4 the stop projection 33' is
on the end of the plunger Ii' and extends into a
smoking.
The displacement pump I3 and its chamber I4
are located in the stem as in the other forms. The
piston I5, however, normally lies not at the
mouthpiece end of the stem but at the bowl end
of the same.
It is normally seated in an up
(i5
ward offset 4I of the guard disc 29’. The adjoin
ing end of the stem is provided with ribs 42 which
guide it into and out of the chamber I4. The
plunger or piston rod I6 extends toward and
through the head I9 which closes the mouth- >
piece end of the stem and is connected with the ,
mouthpiece by a screw 43 or equivalent device
such as a pin or a rivet in such manner that when
the mouthpiece is grasped and pulled oiï of the
stem I2, the plunger is moved the length of the
4
2, 106,774
chamber I4 up against the head I9. Through
radialgrooves-or apertures 44 at the bowl end of
the stem free draft connection is normally main
tained with the bowl I 0. This connection is valve
closed by the plunger I5 in its initial movement
axially outwardly into the chamber I4. Through
the port 45 in the walls of the chamber I4 im
mediately adjoining the head I9 the valve con
nection to atmosphere is established at the
loA
mouthpiece end. ' 'I'his valve connection is nor
mally closed by the skirted extension 46 from the
mouthpiece` II. This connection may be cylin
drical or taper seated as indicated at 4'I and con
stitutes the seating or socketing of the mouthpiece
II upon the stem I2. It extends sufficiently to
ward the bowl from the port 45 to effectually seal
the stem adapted to be reciprocated therein, and
means establishing two valved connections, one
between the bowl and the stem and another be
tween the stem and the atmosphere independent
of the mouthpiece, whereby the bore of the stem
may be shut off from the bowl and the reciproca
-tion of the piston may eject directly from the
stem to the atmosphere the contents of the stem.

however, when the mouthpiece II is seated, af
fords draft connection through the port 45 to the
mouthpiece as shown. Draft is normally there
fore maintained from the bowl to the mouthpiece
but when the mouthpiece is withdrawn to pull
the plunger I5 into forcible contact with the head
I9, the port 45 is opened to atmosphere and the
contents of chamber I4 forcibly ejected there
from.
This form of the invention has particular
adaptation to pipes having curved mouthpieces
as shown in Fig. '7.
.
It also has particular adaptation to pipes of
the nature of cigarette, cigar or other package
type holders as shown in Fig. 8 where corre
Li sponding parts are provided with reference nu
merals -corresponding to the numerals in Fig. 6.
This form of Fig. 8 differs particularly from the
preceding forms in that the bowl I0 is so small
that it accommodates but one end of the pack
aged charge, e. g., a cigarette, cigar or tobacco
in wrappers or containers.
Otherwise the gen
eral arrangement of the parts is the same and
their functionings are the same. The ejector
ejects the residue of the charge when the bcwl
and stem are relatively moved to the dotted line
position. The pump I3 ejects the contents of
of the stem when the mouthpiece and the body
of the stem are relatively moved in the same
manner as in the form of Fig. 6. In this embodi
ment I have substituted for the taper seating 31
draft chamber provided with a fixed abutment at 20
one end, a piston in the stem adapted to be re
ciprocated therein toward and from said abut
ment, and relatively movable parts including said
stem controlling a valve port from the stem to
the atmosphere substantially at the abutment
and independent of the bowl, whereby reciproca
tion of the piston may forcibly eject the contents
of the stem through the port to atmosphere
through co-action with said abutment.
