Improvements in Tobacco Pipes.
I, CHARLES PETERSON, of 53 Grafton Street, in the City and County of
Dublin, Ireland, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to Improvements in Tobacco Pipes, and the object of my
invention is to construct a tobacco pipe in the manner hereinafter described
whereby the tobacco juice nicotine, tobacco dust, moisture, ashes or other objection-
able matter usually entering the stem of a pipe, will be practically prevented from
entering the mouth of the person smoking.
In carrying out my invention 1 construct a bowl which is adapted to receive the
tobacco and which is formed with a stem of suitable shape and dimensions, the
outer or open end of which stem is adapted to have fixed to it a mouthpiece in any
usual manner.
Said stem is formed at about its lower part with a reservoir and a
suitable channel connects the lower part of the bowl with preferably the upper part
of said reservoir. The mouthpiece which may be either curved or straight, is formed
with a bore which is larger at the end which enters the stem of the pipe than at
the opposite end, the reduction in the size of said bore being either gradual or
sudden as may be found most suitable. The reduction in the size of said bore
reducing inversely the pressure induced by drawing or sucking at the small end so
that any particles of dust or other objectionable matter which may be in close
proximity to or within the larger end of said bore, will not be drawn into the
mouth as in the case when the bore is not so formed. That end of the mouthpiece
which enters the stem of the pipe is preferably prolonged so as to pass the channel
which connects the bowl with the reservoir, so that the smoke which is drawn from
the bowl must first pass into said reservoir before it can enter the bore of the
mouthpiece. By this means most of, if not all, the impurities carried with the
smoke will be left or deposited in the said reservoir, and also, if the pipe be tilted,
no moisture or other matter can ordinarily pass from the reservoir into the bore of
the mouthpiece, or from said bore into the bowl.
For the purpose of still further guarding against the entrance into the mouth of
the smoker of any objectionable matter, and also so that the smoke issuing from the
bore of the mouthpiece shall not strike against the tongue, the bore of that portion
of the mouthpiece which is inserted in the mouth is formed at an angle to the rest
of said bore, the direction thereof being upwards so that any impurities collecting
within the said bore cannot readily be drawn into the mouth, and also so that the
smoke will not strike the tongue of the smoker, and the saliva will not re-enter the
mouth.
I wish it to be understood that I do not confine myself to the construction of a
pipe exactly as herein described, as for example, the angular bore hereinbefore
described may be used either in combination with a pipe having a reservoir and
tapering or enlarged bore, as herein described, or said angular bore may be used in
an ordinary pipe not having a reservoir or tapering or enlarged mouthpiece or
neither of them and also that each of the parts may be made of any suitable
materials.

I, CHARLES PETERSON, of 53 Grafton Street, in the City and County of
Dublin, Ireland, Manufacturer, 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 Improvements in Tobacco Pipes, and the object of my
invention is to construct a tobacco pipe in the manner hereinafter described, whereby
the tobacco juice, nicotine, tobacco dust, moisture, ashes or other objectionable
matter usually entering the stem of a pipe, will be practically prevented from
entering the mouth of the person smoking.
In order that my invention may be readily understood, reference is made to the
accompanying drawings wherein like letters of reference indicate corresponding
parts throughout the several figures and in which-
Figure 1, represents a sectional side elevation of a tobacco pipe embodying my
improvements.
Figure 2, represents a sectional side elevation of a tobacco pipe embodying my
improvements, but in which the mouthpiece is of an alternative internal construction
to that shown in Figure 1.
Figure 3 represents a sectional side elevation of a cigar holder embodying one of
my improvements.
Figure 4 is a sectional side elevation of a mouthpiece of a tobacco pipe embodying
one of my improvements.
In carrying out my invention I construct a bowl A which is adapted to receive
the tobacco and which is formed with a stem B of suitable shape and dimensions,
the outer or open end of which stem is adapted to have fixed to it a mouthpiece C
in any usual manner. Said stem B is formed with a reservoir D and a suitable
channel E connects the lower part of the bowl A with the upper part of said
reservoir D as shown. The mouthpiece C which may be either curved or straight,
is formed with a bore F which is larger at the end G which enters the stem. B, than
at the opposite end H in about the ratio of say 10 to 1, and the reduction in the
size of said bore F may be either gradual as shown in Figure 1, or sudden as
shown in Figure 2 or in any other manner as may be found most suitable. The
chanuel E connecting the bowl A with the reservoir D is larger than the bore of
the lip at M hereinafter referred to, preferably in the ratio of 5 to 1, and the end
of the mouthpiece C which is inserted into the stem B is formed or provided with a
portion which projects beyond the channel E leading to the bowl A and which
portion J leaves an annular space K between it and the sides of the reservoir D.
The "lip" L of the mouthpiece C is formed with a bore M extending upwards at
an angle to the bore F as shown, said bore M being smaller than the bore F at H
preferably in about the ratio of 5 to 1.
The advantages of a tobacco pipe constructed in the manner hereinbefore
described, are that it is practically impossible for any objectionable matter such as
tobacco juice, nicotine, tobacco dust, ashes or moisture to be drawn into the mouth
of the person smoking, for the following reasons:-
The bore M being only one fifth as large as the bore F at H, reduces the pressure
induced by the person smoking in the ratio of 5 to 1, consequently the speed of the
smoke at H is one fifth that of the speed of the smoke entering the mouth of the
smoker; then again the bore at H being one tenth as large as the bore at G, in
like manner further reduces the speed of travel of the smoke at G in the ratio
of 10 to 1, consequently the speed of travel of the smoke at G is one fiftieth of the
speed of travel of the smoke when issuing from the bore M, so that the smoke at G,
when the pipe is being ordinarily used, travels at a very slow rate of speed which is

page_text: quite insufficient to carry any objectionable matter to the mouth of the person
smoking. Then also, any saliva which has entered the bore M readily descends by
gravity into the bore F at H and from thence it descends down the said bore F
into the reservoir D, the smoke passing over it without either the smoke or saliva
materially interfering with the passage of the other. Another advantage possessed
by the upwardly extending bore M is that the smoke issuing therefrom will not
strike directly against the tongue of the person smoking, if used in the ordinary
manner, but will be first diffused in the mouth, thereby preventing the tongue from.
becoming blistered.
As stated above, the channel E is five times as large as the bore M, consequently
the speed of travel of the smoke is one fifth in E to the speed thereof at M, which
renders it almost impossible to carry any tobacco dust, ashes or other objectionable
matter from the bowl A. Should, however, some particles be carried with the
smoke from the bowl A, then such particles will be left or deposited in the
reservoir D owing to the sudden reduction of the speed of travel of the smoke at G.
It will be readily understood that by these means it is practically quite impossible
to draw any objectionable matter into the mouth when smoking a pipe constructe.l
as described.
The portion J with which the mouthpiece C is formed or provided, projects
beyond the channel E leading from the reservoir to the bowl, so that any saliva
which may have entered into the bore F cannot fall into the said channel but must
descend into the reservoir D, and also if the pipe be tilted or turned upside down
with the bowl upward and the mouthpiece downward, any tobacco juice or other
matter that is in the reservoir, will descend into the annular space K around the
projecting portion J and will thereby be prevented from entering into the bore of
the mouthpiece.
By simply detaching the mouthpiece from the stem, the whole of the parts may
be readily cleaned.
It will also be readily understood that a pipe constructed as above described,
cannot with ordinary usage possibly become choked in any of the bores, a defect
which is very common to pipes not so constructed, by reason of the speed of travel
of the smoke being the same when leaving the bowl as when entering the mouth of
the person smoking so that all the tobacco juice, nicotine, tobacco dust, ashes, saliva
and other objectionable matter is constantly being drawn or sucked toward or into
the mouth, as the action of such pipes is identical with the action of an ordinary
suction pump.
Another advantage possessed by a pipe constructed in accordance with my
invention, is that on account of the largeness of the bores in comparsion with the
bore M, and on account also of the slow rate of speed of travel of the smoke from
the bowl A to the said bore M, the friction of such smoke with the sides of the
bore F and channel E, is practically nil, therefore a pipe constructed in such a
manner smokes much easier than one not so constructed.
I wish it to be understood that I do not confine myself to the construction of a
pipe exactly as above described, as the details and relative dimensions of the
several parts may be different, also that the bore M (which may be either parallel
or tapered) may also be applied to a cigar holder as shown for example in
Figure 3, or to the mouthpiece of an ordinary pipe as shown in Figure 4; and all
the parts may be constructed of any material or materials or composition which
may be considered to be most suitable.
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 :-
1. In a tobacco smoking pipe, cigar holder or the like, a mouthpiece formed at
its "lip" with an upwardly extending bore M, which bore M is either tapered or of
the same diameter throughout, and is formed at an angle to the portion of the bore-

page_text: with which it communicates, for the purposes and substantially in the manner
described and illustrated.
2. In a tobacco smoking pipe the combination of a bowl A formed or provided
with a stem B having a reservoir D and a passage for the smoke as at E, the outer
end of said reservoir D being adapted to have fixed to it in any suitable manner, a
mouthpiece C having a bore F which is larger at the end Ġ which enters the
reservoir D, than at the opposite end H, the reduction in the size of said bore
being either gradual, as shown in Figure 1, or abrupt, as shown in Figure 2, an
extending or projecting portion J of the mouth-piece passing the channel E and
an upwardly extending bore M of the lip, said upwardly extending bore being
formed at an angle to the portion of the bore F with which it communicates, all
for the purposes and substantially as described and illustrated.
