improvements in or Applicable to smoking Pipes, Cigar Holders,
and the like.
I, HENRY GOTTFRIED SCHRAMM of 521 North Second Street in the City of Camdon
State of New Jersey United States of America, Mechanical 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 :-
The main object of this Invention is to so construct a smoking pipe or Cigar holder
that tobacco or other material can be used therein without drawing the smoke into the
mouth and this object is attained in the manner which I will now proceed to describe
reference being had to the accompanying drawing in which Figures 1 to 7 are
sectional views illustrating different forms of smoking pipe embodying this Invention.
Figures 8 and 9 are sectional views illustrating attachments applied according to
this Invention to the stems of ordinary pipes.
Figure 10 is a sectional view shewing the Invention in connection with a Cigar
holder.
While the smoking of tobacco is advisable in many cases for sanitary reasons or for
fumigating purposes many persons so dislike the taste of tobacco that they are
unable to use the ordinary tobacco pipe because of the necessity of drawing the smoke
into the mouth.
With the view therefore of providing a device which is not open to this objection
the pipe is constructed in the manner hereinafter described and shewn in the drawing.
The bowl a of the pipe shewn in Figure 1 communicates through openings 6 in the
bottom with a chamber d having an outlet e in front of the bowl-Into this chamber
projects a nozzle f forming a continuation of the stem g of the pipe which is con-
structed for being carried in the mouth in the usual manner. The nozzlef terminates
J

page_text: within a short distance from the mouth of the chamber d so that a blast of air forced
through the stem of the pipe will issue in a forcible jet from the end of the nozzle the
jet escaping from the mouth of the chamber d and acting as an ejector to cause a
partial vacuum in said chamber and induce air to pass down through the ignited
tobacco in the bowl of the pipe the smoke thus produced passing up through the
chamber d around the nozzle f and escaping from the mouth of the chamber with the
jet from the said nozzle.
Figure 2 shows a pipe having a somewhat different form of discharge chamber and
ejector nozzle and Figures 3 and 4 show a still further modification in the arrange
ment of these parts the discharge chamber and ejector nozzle shown in Figure 3
being located in the stem of the pipe while those shewn in Figure 4 are at the side of
the bowl next the stem.
If desired the discharge chamber may have its outlet close to the mouth piece so
that the escaping volume of smoke will appear to issue from the mouth in fact, the
construction and arrangement of the discharge chamber and ejector nozzle may be
varied in many ways without departing from the main feature of this Invention one
of the simplest forms of the device being that shewn in Figure 5 in which the nozzle f
and a passage d leading from the bowl of the pipe unite in a single outlet e beneath
and in advance of the bowl of the pipe.
Figure 6 shows a modification of this form of pipe in which the nozzle f and
passage d unite in an outlet e formed in the stem of the pipe above the bowl.
In Figure 7 is shewn a modification of the Invention in which the bowl of the
pipe is closed at the top the nozzle and a passage d in the stem uniting in an
outlet e which communicates with the bowl above the tobacco therein-In this case
the blast from the ejector f causes air to enter the passage d this induced current with
the blast from the ejector being forced through the tobacco and the smoke escaping
through the openings 6 in the bottom of the bowl.
In all the forms of pipe shown the smoking of the tobacco is effected without
drawing the smoke into the mouth so that tobacco of the strongest character can be
smoked by persons unaccustomed to. the use of tobacco of any kind moreover the
choking of the stem of the pipe with nicotine or saliva is prevented.
A more uniform draught and one which can be continued for a longer time is
possible with a forced blast through the stem as in this improved pipe than with the
nward draught of an ordinary pipe.
This improved pipe can however be smoked in the same manner as an ordinary
pipe if desired the mouth e of the discharge chamber in this case being provided with
a suitable damper or valve or closed by a simple plug such for instance as shown by
dotted lines in Figure 2.
In applying the Invention to an ordinary pipe the ejector is made in the form of an
attachment which can be applied to the stem of the pipe at any convenient point
and forms a section of said stem.
In Figure 8 the attachment is located close to the bowl and in Figure 9 it is
located close to the mouth piece the arrangement of nozzle, outlet and induction
passage or chamber in these attachments being substantially similar to that of the like
parts in the various forms of pipe shewn.
Figure 10 shows a cigar or cigarette holder constructed in accordance with this
Invention the stem in advance of the nozzle and outlet in this case having a tapered
opening for the reception of the tip of the cigar or cigarette.
In all of the structures shown in the drawing certain elements are found which are
essential to the proper carrying out of the Invention these elements being the bowl or
holder a jet pipe or nozzle receiving air from the stem a discharge opening of larger
area than the jet opening and a passage through which a secondary current is induced
to flow by the action of the jet the whole forming an ejector whereby the draught
necessary for the combustion of the tobacco is due to the blowing of air through the
stem of the pipe from the mouth instead of to the drawing of smoke through the
stem and into the mouth as in an ordinary tobacco pipe.

page_text: Having now particularly described and ascertained the nature of my Invention and
in what manner the same is to be performed I declare that what I claim is.
First. A smoking pipe or cigar holder having an ejector whereby combustion is
effected by blowing air through the stem instead of by drawing the smoke into
the mouth.
Second. A smoking pipe or cigar holder having a chamber communicating with
the bowl and a jet pipe or nozzle communicating with the stem and projecting into
the said chamber so as to form an ejector.
Third. A smoking pipe or cigar holder having an ejector attachment forming a
section of the stem.
