Improvements in Tobacco Pipes and the like.
I, EZRA LOFTS, of 32 Station Road, Sandown, Isle of Wight, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to tobacco pipes and the like by which the collection of
nicotine is prevented and the smoke cooled before it reaches the mouth of the
smoker. The invention may be carried out in the following manner :-
A pipe may be constructed with any suitable mouthpiece or stem and a bowl
consisting of three chambers one the outermost to receive the tobacco, another
the middle one to form an air chamber or space between the tobacco chamber and
the inner chamber or space, so as to act as a non-conductor and prevent the
relatively cold moist breath of the smoker meeting the hot tobacco and allowing the
one to warm up and the other to cool down. The division walls between the bowl
and the central chamber and the central chamber and the inner chamber are
preferably perforated each with a single small hole so that considerable
restriction is placed on the passage into or out of the central chamber on both
sides.
Another way of carrying out the same idea would be to form what I will call
the bowl proper with the tobacco chamber and the central chamber only and place
that inside an outer bowl or covering the inner chamber being then formed
between the central chamber and the stem or in the latter. However so long as
the more important features are properly carried out the exact details may be
considerably varied and if the separation chamber between the hot tobacco and
the cold breath be provided most of the desired effects may be obtained.
This apparatus may if desired be made in the form of a cigar and obtaining to
a large extent the advantages of a cigar by constructing the bowl with the two
chambers as last described and placing it in the end of an ordinary or special cigar
holder, the third chamber being provided in the stem of the latter, by this means
the smoke is cooled and the nicotine dispensed with and many of the more
advantageous features of a cigar can be obtained with a simple pipe.
Another improvement from which I obtain excellent results consists in providing
a small hole in the stem or mouth-piece so that the smoker will draw in with the
smoke a limited quantity of air which cools and freshens it, besides allowing
part of the return breath to escape instead of being forced into the hotter portions
of the pipe.
Another improvement consists in employing a valve of any suitable description
say a ball valve so arranged that when the pipe is held downwards it closes the
aperture and thus preventing access of air to the burning tobacco it can be held
in the hand without burning for a considerable time, but if the pipe or stem be
held horizontal the valve falls slightly off its seat and allows a small space for the
passage of the smoke, whereas if rapid combustion be required by tilting the pipe
the valve will fall right away from its seat and allow a large passage for the smoke.
A stem connected to the bowl has the advantage of holding the latter so that it
does not move about so readily besides to some extent cooling the smoke as it
passes up the bore of the stem. By this means a larger bore may be employed
which will not so readily choke up while the stem of the valve will reduce the area

page_text: to the required dimensions; also the valve may be taken out at any time and
replaced by a larger or smaller one or one with a larger or smaller stem.

COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes and the like.
I, EZRA LOFTS, of 32, Station Road, Sandown, Isle of Wight, 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:-
This invention relates to tobacco pipes and the like by which the collection of
nicotine is prevented and the smoke cooled before it reaches the mouth of the
smoker. The invention may be carried out in the following manner;―
A pipe may be constructed with any suitable mouth-piece or stem and a bowl
consisting of three chambers one the outermost to receive the tobacco, another
the middle one to form an air chamber or space between the tobacco chamber and
the inner chamber or space, so as to act as a non-conductor and prevent the
relatively cold moist breath of the smoker meeting the hot tobacco and allowing
the one to warm up and the other to cool down. The division walls between
the bowl. and the central chamber and the central chamber and the inner
that
chamber are preferably perforated each with a single small hole so
considerable restriction is placed on the passage into or out of the central chamber
on both sides.
This apparatus may if desired be made in the form of a cigar and obtaining to
a large extent the advantages of a cigar by constructing the bowl with the two
chambers as last described and placing it in the end of an ordinary or special
cigar holder, the third chamber being provided in the stem of the latter, by this
means the smoke is cooled and the nicotine dispensed with and many of the more
advantageous features of a cigar can be obtained with a simple pipe.
Another improvement consists in employing a valve of any suitable description
say a ball valve so arranged that when the pipe is held downwards it closes the
aperture and thus preventing access of air to the burning tobacco it can be held
in the hand without burning for a considerable time, but if the pipe or stem be
held horizontal the valve falls slightly off its seat and allows a small space for the
passage of the smoke, whereas if rapid combustion be required by tilting the
pipe the valve will fall right away from its seat and allow a large passage for
the smoke. A stem connected to the ball has the advantage of holding the latter
so that it does not move about so readily besides to some extent cooling the smoke
as it passes up the bore of the stem. By this means a larger bore may be employed
which will not so readily choke up while the stem of the valve will reduce the area
to the required dimensions; also the valve may be taken out at any time and
replaced by a larger or smaller one or one with a larger or smaller stem.
In the accompanying drawings
Figures 1, 2 and 3 are longitudinal sections showing the improved pipe with
slight modifications.
Figures 4 and 5 are longitudinal sections of pipes similar to those previously
described, but having upright bowls.
Like letters represent like parts throughout the drawings.
In the form shown in Figure 1 the bowl or tobacco receptacle A is in the axial
line of the pipe, B being the central chamber and C the inner chamber nearest
the mouth. The pipe itself may be made of any suitable material, say for example

page_text: wood or meerschaum, the main portion D comprising the two chambers A and B
with the partition E between them in which a small hole E¹ is formed; the end of
the portion D near the mouth of the smoker is reduced in diameter at D' and
upon this fits the mouth-piece F hollowed so as to produce the chamber C and
perforated at F" for the passage of the smoke into the mouth. The division
between chambers B and C is formed by the plug G which fits into the open end
of the chamber B in the piece D and is provided with a T-shaped hole formed of
the single hole G¹ opening into the chamber B of the cross perforation or
T-head G formed at the neck between the plug proper and the head G by which
latter the plug can be removed when required. It will be seen that in smoking
this pipe the hot smoke from the tobacco in A passes by the small hole E' into the
chamber B where it has opportunity to expand and cool down and also to deposit
the nicotine with which it may be charged; it then passes through the small
hole G¹ and is split into two streams at the cross perforation G2 (or more than two
streams may be formed by having more cross perforations) and then in this
divided form enters the chamber C passing around the plug-head G, and being
thus brought into contact with the comparatively thin walls of the mouth-piece F
so that by the time it reaches the mouth of the smoker through the small hole F¹
the smoke has had time and opportunity to cool down and deposit its nicotine and
thus a convenient and healthful pipe can be produced. It will further be seen that
by removing the mouth-piece F and the plug G the whole pipe is perfectly open
and can be easily and effectually cleaned.
The principles of construction adopted in the form shown in Figure 2 are the
same as those previously described but in this case the pipe is formed in three
pieces instead of two and special provision is made for catching the nicotine. In
this case the part D of Figure 1 is divided at D2 producing the two parts D³
and D, D³ forming the tobacco chamber A and the division E between the
chambers A and B and D providing the chamber B. The wall or division E is
made longer than in Figure 1 and the inner end of it is coned at E2 thus preventing
the nicotine which may collect in the chamber B from draining back into the
bowl A which, though a remote_contingency, might possibly occur with the
arrangement shown in Figure 1. The chamber B shorter than in Figure 1 and
the plug G is longer than in Figure 1 but these are merely matters of convenience
and of little or no importance so long as the chambers are provided.
Figure 3 is similar to Figure 2 as regards the bowl section D³ but the inner end
of the second section D is stopped up and provided with a small perforation H
which delivers the smoke into a small chamber formed in the plug G by enlarging
the perforation G'. The chamber C in the mouth-piece F is reduced in size ou
account of the extra space provided in the plug but the principle of operation is
the same as before. Figure 4 may be said to be the same as Figure 1 but the
chamber A which was the bowl in Figure 1 is now used as a sort of extra
chamber, the bowl proper I being added and communicating with A by a small
passage and the end of A being closed by a removable plug or cap K. The
object of this is to provide a bowl of the ordinary description for those who do
not care to use the form of bowl shown in Figures 1, 2 and 3. Figure 5 is similar
to Figure 3 but is altered by the addition of the bowl I; but in this case the
chamber or bowl A is altogether removed and the operating bowl 1 is directly
connected with the wall or division E so that the bowl I and division E can be
drawn out of the chamber B for convenience in cleaning.
In Figure 6 I have shown a convenient form of the before mentioned valve. In
this figure the mouth-piece F is practically the same construction as that shown on
the other figures and fits on to the reduced end D' of D or D' into which latter at
this same end, fits the perforated plug or valve seat J through whose bore or
central passage J' passes the stem L¹ of the valve L.
With the last described arrangement it will readily be seen that when the pipe
is held downwards the valve K falls on to the seat J and closes the aperture J¹
thereby preventing access of air to the burning tobacco and when it is held

page_text: horizontally the valve K falls away from the seat J and allows a small space for
the passage of the smoke. If desired suitable means may be provided for limiting
the opening movement of the valve K.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A tobacco pipe or the like containing three chambers such as A B and C
with perforated divisions between substantially as described and illustrated in the
accompanying drawings.
2. A tobacco pipe provided with two chambers such as B and C substantially as
described.
3. A tobacco pipe consisting essentially of the parts D F and G substantially as
described and illustrated in Figure 1 of the accompanying drawings.

7. A tobacco pipe consisting essentially of the parts IE D F and G
substantially as described and illustrated in Figure 5 of the accompanying
drawings.
8. In a tobacco pipe comprising two or more chambers the combination with
the wall plug or equivalent separating two adjacent chambers of a valve substan-
tially as described and illustrated in the accompanying drawings.
