Improvements in Smoking Tubes.
I, JAMES MARTIN EDER, of 202, West 86th Street, New York City, in the
County and State of New York, United States of America, Inventor, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement: —
This invention relates to improvements in tobacco smoking tubes, and it has
for its object to provide a smoking tube of simple and comparatively inexpensive
construction, and so made that the bowl portion may be readily filled by forcing
it endwise into tobacco contained in a package without touching the tobacco with
the hands; and further to provide a simple means for ejecting ashes of the con-
sumed tobacco, the said means also providing on its exterior a long sinuous pas-
sage for the smoke, thus serving to cool the smoke before it enters a person's
mouth.
I will describe a smoking tube embodying my invention and then point out the
novel features in the appended claim.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding parts
in all the figures.
Figure 1 is a longitudinal section of a smoking tube embodying my invention
and showing the parts in position for smoking.
Figure 2 is a section showing the parts in position for ejecting ashes;
Figure is a section on the line 3-3 of Figure 1; and
Figure 4 is a front end view of the smoking tube.
The smoking tube comprises a bowl section 1, a stem section 2, and a mouth
piece 3. The mouth piece is shown as having removable connection with the
stem, but it is obvious that it may be made integral therewith without departing
from the spirit of my invention. The several parts above described, when
assembled, present the appearance substantially of a cigar.
Arranged within the rear end of the bowl 1 is an interiorly screw-threaded
block 4, which has an exteriorly screw threaded extension 5, to engage with a
screw thread formed in the forward end of the stem section 2. A solid threaded
plunger rod 6 is movable through the block 4, and it is also movable relatively
to the stem section 2 in a longitudinal direction, but it is secured from rotary
motion relatively to said stem.
As a means for preventing the rotary motion of the plunger relatively to the
stem, I have shown the plunger as having an angular head 7 engaging in a corre-
spondingly shaped opening through the stem, but obviously other means may
be provided for preventing such rotary movement, such for instance, as extend-
ing a rib outward from the end of the plunger to engage in a channel formed in
the stem.
Removably attached to the forward end of the plunger rod so as to move in
the bowl section 1 is a piston 8, which has a diameter substantially equal to the
inner diameter of said bowl, and it may have perforations through it for the pas-
sage of smoke, and it may be here stated that the screw thread engagenient

page_text: between the plunger rod and the block 4, is sufficiently loose to permit the smoke
to pass around the outer surface of the rod or between said rod and the block,
and as the smoke will have a tendency to follow the channel of the thread
before it reaches the head 7 to pass through the openings therein, it will be
considerably condensed and cooled before it passes into a person's mouth.
The front end of the bowl section 1 is bevelled off to a sharp edge, so that it
may be forced bodily into tobacco contained in a package, and by cutting its
way through said tobacco, a portion will be forced into the bowl. "To facilitate
this cutting operation, I. may provide the end portion with longitudinally dis-
posed channels 9 which will form teeth 10 at the extreme end.
In operation, when it is desired to fill the bowl with tobacco, the parts are to
be in position, indicated by Figure 1, and then by forcing the bowl into the
tobacco, it will become filled as before described.
The threads of the plunger rod 6 and of the portion 5 are in opposite direc-.
tions, and as the plunger is much longer than the portion 5, it is obvious that
the threads must be so related in pitch that on the movement of the stem por-
tion 2 away from the bowl portion by a rotary movement of said stem or the
bowl and to the limit of the stem's motion on the portion 5, the plunger will be
moved its entire length to eject the ashes of consumed tobacco, as indicated in
Figure 2. Of course, on a reversed rotation of the stem of the bowl, or bowl
relatively to the stem, the plunger will be drawn back to its normal position,
as indicated in Figure 1, while the stem and bowl are moved with their ends
together.
A smoking tube embodying my invention may be readily taken apart for clean-
ing, that is, the stem portion may be removed from the bowl portion, and by
removing the piston the plunger rod 6 may be removed from the block and also.
from the stem, and then the stem and bowl may be cleaned in any desired manner
and the plunger may be cleaned by washing or wiping with a cloth or the like.
Thus it may be seen that the plunger rod is much more easy to clean than is a
plunger having a longitudinal perforation for the passage of smoke.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
In a smoking tube, a block 4 having an interior and an exterior screw thread
of opposite and different pitch for the purpose of producing by rotation of the
stem, a greater longitudinal movement of the plunger than of the stem, sub-
stantially as described.
