SMOKING APPARATUS
Abstract
An apparatus is provided in the form of a water pipe having a
lower water containing vessel and an upper smoke containing vessel
in which a cigarette or other tobacco supporting means is mounted.
The lower vessel serves as a base for the apparatus and is formed
with an upwardly facing opening while the upper vessel is inverted
so that its opening faces downwardly in generally over-lying
relationship with the lower vessel opening. A fitting serves to
sealingly engage the respective openings and to support the upper
vessel in its over-lying relationship relative to the lower vessel.
Smoke which is accumulated and contained in the upper vessel is
drawn downwardly through an up-standing conduit which extends
through the fitting so as to draw the smoke through water contained
in the lower vessel. An outlet passage communicates between an
upper portion of the lower vessel and laterally outwardly of the
fitting to a mouthpiece affixed to a flexible tubing, while an
intake passageway is provided from the upper vessel laterally
outwardly of the fitting for drawing in fresh air for sustaining
combustion of the tobacco in the upper vessel. This intake passage
is either filtered or equipped with a one-way ball valve to prevent
the escape of tobacco smoke from the upper vessel chamber.

Description
BACKGROUND OF THE INVENTION
In general, the present invention relates to utensils and devices
for facilitating smoking of tobacco or the like, and more
particularly to an improvement in water pipes in which smoke of the
burning tobacco is drawn through water or other liquid.
Water pipes are one of the oldest forms of smoking utensils. By
means of this device, smoke is inhaled or otherwise consumed by the
user after it is drawn through a vessel of water. In general, the
smoke is bubbled through the water causing an immediate and
effective cooling of the smoke. The use of the water pipe is
particularly desirable in the case of stronger tobaccos, such as
harsh Turkish tobacco.
It has heretofore been proposed to use water pipes not only for the
smoking of loose tobacco, such as pipe tobacco, but also be smoking
cigarettes. In either case, the bowl of tobacco or a cigarette
holder is disposed so that the smoke may be drawn from the burning
tobacco through a conduit submerged in a vessel of water, causing
the smoke to filter or bubble through the water. The water cooled
smoke is collected in an upper region above the water line of the
vessel and drawn therefrom into a mouthpiece held by the user, such
as at the end of an elongated flexible conduit. A smoking suction
applied to the mouthpiece causes the smoke and air to be drawn
through the cooling water and eventually into the mouth of the
smoker. Such a device is disclosed in a previously issued U.S. Pat.
to Grant, No. 1,579,703.
In the smoking of many tobaccos, particularly the stronger and
harsher tobaccos, an odor may be produced which is pungent and
disagreeable at least to some persons. This odor may permeate the
room, building, and even the clothing of those present. To many,
even the smoke from ordinary cigarettes is bothersome and sometimes
irritating to the eyes and throat.
It is accordingly one object of the present invention to alleviate
the problem of noxious smoke fumes normally produced by smoking
tobacco, and particularly as to the smoking of harsh or strong
tobacco, such as Turkish cigarettes or tobacco. In this regard, it
is a more particular object of the present invention to provide an
apparatus which permits the smoking of tobaccos, and even harsh
tobaccos, without irritating others who are present within the same
room, building or other confined area, and at the same time to
protect the smoker himself from taking in hot and injurious tobacco
smoke.
To a certain extent, devices heretofore proposed have met the
foregoing objects. For example, there exists on the market today,
an apparatus for smoking cigarettes in which a burning cigarette is
disposed within a separate vessel which is enclosed except for a
slender conduit running to another un-attached and spaced apart
vessel in which smoke cooling and filtering water is stored. The
two vessels are mounted on a platform in spaced apart relationship
and an electrical pump is employed to drive the smoke from the
first vessel containing the burning cigarette through the slender
conduit into and through the water in the second vessel and from
there outwardly to a mouthpiece communicating with the upper region
of the water vessel. The water vessel thus functions in a manner
similar to the ancient water pipe. Although in this apparatus, the
first vessel does partially contain the smoke and prevent its
dispersement into the room, the effect of the electrical pump is to
continuously force smoke into and through the water vessel and
outwardly of the mouthpiece. Thus when the user removes the
mouthpiece, the smoke is continually spurting outwardly thereof and
into the surrounding area. Also as the smoke is constantly forced
through the mouthpiece there is an unpleasant sensaion to the user
in that the smoke is injected into his mouth rather than being
drawn in by inhaling.
Even apart from the foregoing disadvantages, this prior apparatus
has been found undesirable in that it is too expensive to
manufacture, too cumbersome to use in that it requires the
operation of an electrical motor-pump, and too heavy and bulky to
permit portability.
With these shortcomings in mind, it is a further object of the
present invention to provide in a smoking apparatus the features
and advantages mentioned above together with a construction which
is compact, lightweight and thus easily transported and handled,
and which is capable of economical mass manufacture.
SUMMARY
Briefly, in accordance with the present invention a smoking
apparatus is provided in the form of a water pipe having a lower
water containing vessel and an upper inverted smoke containing
vessel in which a cigarette or other tobacco supporting means is
mounted. The lower vessel serves as a base, which for example may
be set on a table, and is provided with an upwardly facing opening
while the upper vessel is inverted so that its opening faces
downwardly in generally over-lying registration with the lower
vessel opening.
Connecting these vessels is a fitting means which sealingly engages
the respective vessel openings and serves to support the upper
vessel in the over-lying relationship with respect to the lower
vessel. The cigarette or tobacco supporting means is carried by the
fitting means so as to dispose the burning tobacco in a lower
region of the upper vessel. Smoke is accumulated and contained by
the boundaries of the upper vessel. An upstanding conduit means
extends from the upper vessel downwardly through the fitting means
with a lower end of the conduit below the level of water contained
in the lower vessel.
The fitting means is formed with a smoke outlet passage which
communicates between an upper region of the lower vessel, above the
water line, and extends laterally outwardly of the fitting to a
mouthpiece which may be attached at the end of a flexible tubing.
An air intake passageway is also formed in the fitting means so as
to communicate fresh air with the interior chamber of the upper
vessel. This intake passage is provided with a smoke trap means
which may be a filtering material or a one-way ball valve to
prevent the escape of tobacco smoke from the upper vessel chamber
and yet permit the intake of air when smoke is drawn from the upper
vessel into and through the water reservoir of the lower
vessel.
The two vessels and the fitting means connected therebetween forms
a light-weight, compact and portable unit which may be easily
transported by the user. A handle may be provided for enhancing the
portability of the device.
It is contemplated that one advantage of the present invention is
to permit its use in public places, such as in restaurangs, where
the smoking by some partrons will not disturb other customers. In
this respect, the present apparatus is capable of large volume
economical manufacture, thus making practical the purchase and use
of this device in public transportation, buildings and other public
accommodations.
It is also contemplated that the device will be sold to and used by
individuals in their homes and other private buildings where the
advantages of this apparatus can be utilized. In this regard and in
addition to the above mentioned advantages, the smoking apparatus
of the present invention has the desirable characteristic of
conserving smoke. That is, the smoke generated by the burning
tobacco is accumulated within the upper vessel until the user
withdraws the smoke therefrom by inhaling. It has been found that
the smoke accumulated with the upper vessel can be stored for
several minutes, even after the combustion of the tobacco has been
completed. Thus, the accumulated reservoir of smoke may be consumed
at a rate suited to the user and not necessarily determined by the
time it takes for the tobacco to be fully burned.
Additional features of the present invention provide a detachable
tobacco bowl which may be used in place of the cigarette holder for
smoking loose pipe tobacco.
The mouth or opening of the lower vessel is made large enough to
pass ice cubes therethrough, so that the water in the lower vessel
may be made ice cold to increase the cooling effect on the
smoke.
These and further objects and various features and advantages of
the smoking apparatus in accordance with the present invention will
become apparent to those skilled in the art from a consideration of
the following detailed description of particular and exemplary
embodiments thereof.
BRIEF DESCRIPTION OF DRAWINGS
Reference will be made to the appended sheets of drawings in
which:
FIG. 1 is a perspective view of one particular embodiment of the
smoking apparatus constructed in accordance with the present
invention.
FIG. 2 is a vertical sectional view of the apparatus of FIG. 1
taken along lines II--II therein.
FIG. 3 is a partial vertical sectional view of the apparatus of
FIG. 1 taken along the section lines III--III indicated
therein.
FIG. 4 is a partial vertical sectional view, similar to FIG. 3,
although here illustrating an alternative preferred embodiment of
the present invention.
FIG. 5 is also a partial vertical sectional view similar to FIGS. 3
and 4, here showing a further alternative and preferred embodiment
of the smoking apparatus of the present invention.
FIG. 6 is a view similar to FIGS. 3 through 5 showing still another
alternative and preferred embodiment of the present invention.
With reference to FIGS. 1 and 2, a smoking apparatus 11 constructed
in accordance with the present invention generally comprises a
lower vessel 12 adapted to be partially filled with water or other
liquid 13 and an upper smoke containing vessel 14 which is inverted
and disposed in over-lying registration with lower vessel 12. A
fitting means 16 serves to engage and join a upwardly facing top
opening 17 of lower vessel 12 and a downwardly facing bottom
opening 18 of the upper vessel 14. By this arrangement, vessels 12
and 14 and their respective openings are in substantial vertical
registration or alignment and the upper vessel 14 is supported by
the lower vessel through the interconnecting fitting means 16. The
apparatus including both vessels may thus be transported as a unit
with a base 19 of lower vessel 12 providing a stable support
surface which may be disposed on a table or other planar
surface.
Tobacco support means, here provided by a tubular metal member 21,
is carried by an upper portion of fitting means 16 so as to dispose
and support combusting tobacco, such as the burning cigarette
illustrated here within the upper vessel 14.
Vertically extending conduit means is provided for communicating
the interior of upper vessel 14 with the water reservoir of the
lower chamber. The conduit means may be provided by an upstanding
tubular conduit 22 disposed in communication with the tubular metal
cigarette holder 21 for drawing air and smoke from vessel 14
downwardly through the burning embers of the cigarette, through
holder 21 and conduit 22 and outwardly of the lower end of the
conduit into the water filled reservoir of the lower vessel. As
illustrated here, metal holder 21 and conduit 22, which may be
formed of plastic, are mounted within and supported by a
through-bore 23 formed in fitting means 16. Thus the conduit means
provided by these elements passes through the fitting means between
the upper and lower vessel chambers.
To pass the smoke to the user and serve as a means for drawing the
smoke through the water of the lower vessel, a mouthpiece means is
provided communicating with an upper region 24 of vessel 12, above
the water line 26 therein. With reference to FIGS. 1 and 3, the
mouthpiece means may be provided by a mouthpiece 27 connected by a
flexible conduit 28 to an outlet passage 29 formed in fitting means
16 and in which a tubular connector 31 is mounted. Connector 31
provides for attachment to hose or flexible conduit 28. It is
observed that passageway 29 extends upwardly from region 24 of
lower vessel 12 and makes a right hand turn so as to pass laterally
outwardly of the fitting means 16 between the vertically spaced
rims of openings 17 and 18 of the vessels. Alternatively, connector
31 may be itself used as a mouthpiece thereby eliminating the
flexible hose.
In a similar manner, an intake means is provided, here in the form
of a passageway 32 defined in fitting means 16 for passing fresh
combustion air and oxygen into the upper vessel 14. It is necessary
to provide an intake of fresh air periodically during the
combustion of the cigarette or other tobacco, to sustain the
burning. Passageway 32 extends laterally inwardly of fitting means
16 between the spaced vessel rims and then turns vertically
upwardly into the upper combustion chamber. As described more fully
hereinafter, the intake means may be provided with a smoke trap in
the form of a filter or one way ball valve to inhibit the escape of
smoke from the apparatus.
By this arrangement of components, a compact easily transportable
smoking utensil is provided in which the smoke is substantially if
not completely contained, preventing its escape into the
surrounding room or area. Moreover, this feature of containing the
smoke is provided in combination with the lower water filled vessel
for cooling the smoke prior to its consumption. Both the containing
of the smoke and the processing thereof through the water vessel
are desired characteristics in smoking strong and odoriferous
tobaccos, such as Turkish tobaccos and other harsh vegetational
plants prepared for smoking.
For convenience, the portable unit may be provided with a handle
means, such as here shown by opposed handles 35 and 36. In this
instance, handles 35 and 36 of the handle means are attached to a
neck 37 of lower vessel 12 by a collar 38. However, the handle
means may be in any desired configuration and attached at any
suitable location to the pair of vessels and/or to the fitting
means 16.
Vessels 14 and 12 may be formed of glass, non-toxic platic or any
other suitable material and may be either transparent or opaque.
Upper vessel 14 is preferably of a transparent material to permit
monitoring of the smoke and burning tobacco therein. As a certain
amount of somke residue may build up on the inside of upper vessel
14, it has been suggested that an amber color glass or plastic is a
preferable material.
The particular shape and dimensions of these vessels is not
believed critical except that sufficient volume should be provided
by the upper vessel 14 to store adequate qunatities of air and
oxygen for facilitating the combustion of the tobacco. This volume
should be sufficient to sustain combustion during intervals between
the intake of fresh air through passageway 32. Also, the height of
vessel 14 should provide generous space between the burning embers
of a cigarette and the top of the chamber. These considerations
generally result in a size for lower vessel 12 which is somewhat
smaller than the upper vessel. as indicated in this instance by the
relative dimensions in the drawings. As an example of suitable
dimensions, for an overall apparatus height of approximately 13 to
14 inches, the upper vessel 14 may have a height of approximately 9
inches with the lower vessel having a height of 4 inches and
approximately one half to three quarters of an inch spacing
therebetween at fitting means 16. Although the vessels and fitting
means may be of any suitable cross section, in this instance
annular or cylindrical components are employed to facilitate the
fitting engagement between the various parts. In this instance
upper vessel 14 has a diameter of approximately 4 inches while the
lower vessel diameter is about 3 1/2 inches.
The dimensions of openings 17 and 18, similarly are not believed
critical. However, it may be desirable to form the neck 37
associated with opening 17 of lower vessel 12 to have sufficient
size, such as 2 to 3 inches in diameter, to pass ice cubes into the
lower water filled chamber. In this regard, it is many times
desirable to cool water 13 below ambient temperature to enhance the
cooling of the smoke and for this purpose ice water is very
convenient.
With respect to opening 18 of the upper vessel and the neck 39
associated therewith, these portions should be dimensioned to slip
over the tobacco supporting means, which in addition to the tubular
cigarette holder may include a dish-shaped ash tray 41, and/or
removable tobacco bowl 42, shown in FIG. 6 and described more fully
hereinafter. Because of these requirements, the necks and/or mouth
of both vessels may be of the same or approximately same
dimensions. In such case, the formation of fitting means 16 is
simplified in that it provides for the joining of two like sized
vessel openings.
Although fitting means 16 may be of any suitable size and
donfiguration, two preferred embodiments are illustrated in the
drawings. In FIGS. 1 through 3, fitting means 16 is provided by a
solid resilient material, such as rubber, and takes the form of a
double ended stopper 43. Stopper 43 is of a generally cylindrical
shape having opposed axial ends formed with circumferential tapers
44 and 46 for physically, sealingly engaging mated flared portions
associated with openings 17 and 18 of the vessels. Using a slightly
resilient, hard rubber stopper material, a snug and structurally
sound union is achieved.
Through-bore 23 and passageways 29 and 32 are readily formed within
stopper 43. An upper end of stopper 43 may be provided with an
annular recess 47 coaxially inwardly of tapered portion 44. The
tobacco supporting means in the form of tubular member 21 and ash
tray 41 including a stand portion 49 therefor may be nested within
this recess. However, such a recess is not necessary, and the
various components may be mounted so as to extend from an
un-recessed upper surface of the stopper.
An alternative and preferred embodiment of the fitting means is
illustrated in FIG. 5, in which primed reference numerals refer to
corresponding components in FIGS. 1 through 3. Thus in FIG. 5,
fitting means 16' is in the form of a connecting member 51 of
generally cylindrical configuration and having opposed threaded
portions 52 and 53. These threaded portions are disposed at
opposite axial end portions of member 51 for engaging
correspondingly threaded portions 54 and 56 of vessel openings 17'
and 18' associated with lower vessel 12' and upper vessel 14'
respectively. Interposed between the opposed threaded end portions
52 and 53 of member 51, a member body portion 57 is provided in
which pissageways 29' and 32' and through-bore 23' are formed.
Connecting member 51 may be formed of a molded, hard, non-toxic
plastic, or metal or of any other suitable material. As in the case
of the embodiment in FIGS. 1 through 3, upper and lower vessels 14'
and 12' may be formed of glass, non-toxic plastic or of any other
suitable material and may be dimensioned as described above.
With further reference to the embodiment of the invention shown in
FIGS. 1 through 3, intake means, here provided by passageway 32,
may be equipped with smoke trap means for inhibiting the escape of
smoke from the upper vessel. This smoke trap means may be provided
by a gravity actuated one-way ball check valve assembly 61.
Assembly 61 is provided by a light-weight ball 62, such as formed
of a light plastic or hollow material arranged to seat and seal
against an upwardly facing annular valve seat 63. Valve seat 63
circumscribes or may be part of passageway 32 such that ball 62 may
be forced by gravity to seat and close off the passageway.
To maintain ball 62 in generally over-lying position relative to
valve seat 63, means may be provided for afforing limited upward
displacement of the ball valve 62 off of valve seat 63. In this
instance, such means is provided by an air pervious cage or similar
structure 64 mounted over valve seat 63 and ball 62. Cage 64 serves
to permit upward displacement of the ball 62 but prevent its
movement out of proximity to the valve seat.
In operation, the effect of drawing air and smoke to the user by
puffing on mouthpiece 27 causes ball 62 to lift off of the valve
seat and allow an intake of air through passageway 32. In
particular, by drawing on mouthpiece 27, the pressure within upper
region 24 of lower vessel 12 is reduced. This causes the ambient
pressure within upper vessel 14 to force smoke downwardly through
the cigarette or other tobacco, through the inner passage of
conduit 22 and outwardly of the lower end thereof through the water
and into the upper portion of the lower vessel where the smoke is
drawn off to the user through outlet passageway 29. During this
process, there is slight reduction in air pressure within vessel 14
which causes the ambient air pressure externally of the apparatus
to force its way in through passageway 32 and lift valve ball 62 so
as to permit the intake of fresh air and oxygen for combustion.
During intervals between comsumption of the smoke by the user, the
pressures in the various vessels equalize with the atmospheric or
ambient pressure causing the ball to seat and block the otherwise
escaping smoke.
An alternative and preferred embodiment of the smoke trap means is
illustrated in FIG. 4, in which double primed reference numerals
refer to corresponding parts described hereinbefore. In this
embodiment, a filter or filter material 71 is disposed within
intake passageway 32". The filter 71 may be of a fibrous filtering
material, or any substance or structure which forms a labyrinth or
baffling in passageway 32". Such a filtering structure does not
absolutely preclude the passage of smoke outwardly of the intake
means, however it has been found to substantially inhibit escaping
smoke which otherwise tends to flow freely outwardly of passageway
32". In the absence of any filtering or baffling structure within
passageway 32", slight convection currents or a slight differential
pressure between inside and outside of vessel 14 causes an outflow
of smoke. Filter 71 has been found effective in substantially
inhibiting such out flow.
With reference to FIG. 6, an alternative embodiment of the tobacco
supporting means is illustrated, and wherein triple primed
reference numerals refer to corresponding parts described above. In
this embodiment, a detachable tobacco bowl 42 is provided, similar
to the bowl of a tobacco pipe, for removable mounting to the upper
end of tubular cigarette holding and supporting member 21. If it is
desired to smoke loose tobacco, rather than a cigarette, bowl 42
may be mounted as illustrated in FIG. 6 and filled as illustrated
with loose tobacco. The detachable mounting of bowl may be provided
by any suitable means, and is here provided by a lower annular
recess 72, of slightly larger dimension than the circumference of
member 21 for fitting thereover. Recess 72 may be provided with an
O-ring seal 75 as illustrated for sealing recess 72 with the
circumference of tubular member 21'". In use, smoke and air pass
through a lower passageway 73 in the bottom of tobacco bowl 42 and
into the inner passageway of tubular member 21'" and of conduit 22
'",. Thus passageway 73 is disposed in communication with the open
end of the cigarette holder member and in communication with the
conduit means extending to the water reservoir of the lower
vessel.
To use tobacco bowl 42, upper vessel 14'"is removed from fitting
means 16'" to provide access to cigarette holding member 21'" and
bowl 42 is slipped thereon. The tobacco is placed within the bowl
and lit and vessel 14'"is repositioned on the fitting means.
With further reference to FIGS. 1 through 3, the use of the
apparatus for smoking a cigarette is as follows. First, vessel 14
is removed and the lower end of a cigarette is snugly inserted into
the upper open end of metal member 21. For this purpose, member 21
is provided with an interior cylindrical portion 75 and a tapered
or flared portion 76, as best shown in FIG. 3. The upper
cylindrical portion 75 serves to receive and hold commercial
machine formed cigarettes, while the tapered portion 76 is
effective to hold the end of a hand-rolled cigarette.
The upper end of the cigarette is not lit and the vessel 14 is
replaced. During smoking, the ashes fall from the cigarette into
the dish-shaped ash tray 41 which underlies the cigarette and is
coaxially mounted relative to member 21. In particular, ash tray 41
is provided with a centrally located opening 77 coaxialy mounted
over member 21 and the stand portion 49 positions the ash tray just
below the upper end of member 21.
Member 21 is preferably formed of a metal or other high temperature
material, so as to withstand the temperatures of the burning embers
as the cigarettes burns to completion. The conduit means here
provided by a combination of a tubular metal member 21, for holding
the cigarette, and a lower plastic conduit 22, may of course be
provided by a single piece tubular conduit of metal.
While only a limited number of embodiments of the present invention
have been disclosed herein, it will be readily apparent to those
persons skilled in the art that numerous changes and modifications
may be made thereto without departing from the spirit of the
invention.
For example, it is contemplated that it may in some cases be
desirable to provide a smoke trap means in or adjacent to outlet
passageway 29 to prevent the escape of even the limited amount of
smoke within upper region 24 of lower vessel 12. For this purpose,
the smoke means may be similar to the one-way ball valve assembly
61 shown in FIG. 3 for the intake passage 32 or similar to the
intake passage filter 71 shown in FIG. 4.
Accordingly, because of the possible numerous changes and
modifications available, the foregoing disclosure and description
of the invention are for illustrative purposes only and do not in
any way limit the invention which is defined by the following
claims.
