Description
BACKGROUND OF THE INVENTION
The present invention relates to the art of smoking devices. More
particularly, this invention relates to a smoking pipe of the type
in which, during inhalation, the smoke is drawn through water or
other suitable liquid before entering the lungs of the user.
Specifically, this invention relates to a smoking pipe of the
aforedescribed type which includes finger controlled orifice means
for controlling the ratio of and velocity of smoke and air that is
inhaled.
In general, smoking pipes of this general character, i.e., having
provision for drawing the smoke through water and termed "water
pipes" have been in use for many years. Examples of such devices
are shown in U.S. Pat. No. 77,096 of Apr. 21, 1868, to Robbins,
U.S. Pat. No. 183,626 of Oct. 24, 1876, to Bingham, U.S. Pat. No.
586,149 of July 13, 1897, to Turner, U.S. Pat. No. 722,405 of Mar.
10, 1903, to Ganim, and U.S. Pat. No. 199,607 of Nov. 17, 1964, to
Zia.
However, none of these devices contain provisions for controlling
the amount of smoke that is inhaled. The general concept of a
smoking pipe including a water chamber through which the smoke is
drawn before entry into the mouth of the user and which also
includes valve means associated with the smoke passage or passages
is shown in U.S. Pat. No. 1,582,670 of Apr. 27, 1926, to Eckelmans.
However, in this arrangement the water chamber has less volume than
the bowl or smoking material receptacle. A finger controlled vent
orifice associated with a smoking device is shown in U.S. Pat. No.
3,336,929 of Aug. 22, 1967, to Williams. However, the device of
this patent is directed to a cigarette holding and reverse smoking
device. There is no provision of a water chamber and in use the
orifice is always open during inhalation of a cigarette held
therein and closed when the smoke is puffed out through the held
cigarette. The only air intake during smoking is through the
cigarette.
Specifically, this invention is an improvement in the "water pipe"
of my prior filed application Ser. No. D 262,484 of June 14,
1972.
SUMMARY OF THE INVENTION
While certain specific aspects and advantages of the present
invention will be apparent from the ensuing description of a
preferred embodiment, this invention has for a principal object to
provide a smoking pipe including a liquid accommodating flask, a
mouthpiece associated with the upper portion thereof, a pipette or
tube extending into the flask to a point above the bottom thereof,
a smoking material-receiving bowl at the top of the pipette, and a
finger controlled orifice means associated with a portion of the
flask above the level of liquid therein.
A more specific aspect of the invention is to provide a smoking
pipe including a flat bottomed, round, liquid receiving flask, an
opening at the top of the flask, a centrally disposed apertured
pipette-accommodating stopper of natural rubber or high grade
synthetic rubber to cooperate with such opening to provide an
air-tight seal between the pipette and flask, a bowl at the upper
portion of the pipette, a mouthpiece-forming, tubular extension
projecting outwardly from the upper portion of the flask on one
side of the stopper-accommodating opening and a finger-controlled
orifice means at the upper portion of the flask on the other side
of such stopper-accommodating opening.
From a more specific aspect, the last mentioned opening has an
apertured rubber or high grade synthetic rubber removable stopper
in sealing relation with such orifice. Preferably, the stopper has
two air passages therethrough.
Additionally, the invention provides a restriction in the upper
portion of the pipette and a conical smoking material receiving
bowl communicating directly with such restriction.
Further and more specific objects and advantages will be more
readily apparent from the following description when taken in
connection with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a vertical sectional view of an embodiment of the
invention.
FIG. 2 is a top plan view thereof.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
As illustrated in the drawings, the smoking pipe of the invention
includes a main body or flask A, an integral mouthpiece forming
extension B, a stopper C, a pipette and bowl combination member D
carried thereby, and a finger controlled orifice means E for
controlling inhalation.
The body or flask can be made of glass, a suitable plastic
material, or a heat-resistant material such as PYREX glass. The
pipette and bowl member must be made from a heat-resistant material
such as PYREX glass or, if desired, a suitable material such as
aluminum.
The flask includes a rounded main body 1 having a flat bottom 2.
The top of the flask is provided with a centrally disposed opening
3 for receiving the stopper C. The stopper, made of, for example, a
natural rubber or a high grade synthetic rubber, is provided with a
central bore 4 through which is inserted the pipette portion 5 of
the pipette-bowl member D. During assembly, the member D in wet
condition is inserted by a twisting movement into the bore of
stopper C while it is wet. Then, with the rim of the flask aperture
or opening 3 in wet condition, the stopper, while wet, is removably
inserted therein to provide an air-tight seal between the pipette
and flask.
The mouthpiece extension B includes a tubular projecting portion 6
and an outwardly flared mouth-receiving end portion 7 of a size to
snugly accommodate the user's lips as shown.
At the upper portion of the flask body 1 on the opposite side of
the opening 3 from the tubular projecting portion 7 and in the same
general vertical plane therewith, see FIG. 2, is an opening 8. A
stopper 9 of the same material as stopper C is inserted in this
opening. The stopper 9 is provided with two axial bores 10 and 11
of about 3 mm. internal diameter. This stopper is smaller than
stopper C so that the opening or closing of the bores 10 and 11 can
be controlled by the user's index finger.
The flask body 1 is approximately of 500 ml. internal volume or
capacity and in use is half filled with liquid such as water. L
denotes the liquid level. The liquid level is somewhat crucial
since if too much water is put into the flask so as to raise the
level above that for approximately 250 ml. of water, then the user
would be inhaling water. It has been found that the above-mentioned
size flask is ideally suited for ease of use.
The pipette-bowl member D includes the pipette portion 5 which is
approximately 41/2 inches in length and when inserted has its lower
end approximately 3/4 inch above the bottom of the flask. The upper
end portion of the pipette portion 5 has a 1/4 inch long restricted
portion 12, the top of which communicates directly with the
interior of the conical bowl 13. This shape of the bowl guides the
smoke into the pipette and thus into the body of the flask. The
bowl of the pipette is approximately 8 mm. internal diameter, the
restriction is from about 2.4 to 2.9 mm. in internal diameter.
The bowl 13 is of approximate 1 inch internal diameter at the top
and about 3/4 inch in height tapering inwardly to communicate
directly with the upper end of the restricted portion 12.
As shown in FIG. 2, the axis of the tubular extension or projecting
portion 6, and the axes of the openings 3 and 8 all lie in a common
vertical plane through the flask body 1. This coupled with the
rounded or spherical shape of the flask as well as its flat bottom
facilitates use and handling of the device.
In one manner of use, the flask is half-filled with liquid such as
water, wine, or a suitable tasty or pleasing mouth wash. A pinch of
smoking material such as tobacco, or a smokable medicinal herb is
placed in the bowl so as to cover the lower opening therein. The
user then exhales and places his lips snugly inside the flared
mouthpiece. He then places his finger over the bores in stopper 9.
A lighted match is held over the bowl during fitting of the lips
and closing bores 10 and 11. The user then inhales slowly and
evenly until the contents of the bowl have been drawn into the
water. Then the finger is removed and inhalation is continued until
the flask is cleared of smoke.
In proceeding as above, the user has inhaled the smoke emanating
from the small amount of smoking substance after it has been
ignited, drawing it through the restriction in the pipette just
beneath the bowl proper and into the water. Inasmuch as
considerable pressure or inhalation effort has to be exerted to
draw the smoke through the lower opening in the bowl, the smoke is
caused to be drawn deeper into the user's lungs.
With the provision of the stopper 9 having the bores 10 and 11
therethrough, the user can remove his finger from these bores after
the smoke has entered the body of the flask during initial
inhalation, thus causing the smoke to enter the lungs at a more
rapid rate than would be the case if the only external air source
would be through the bowl, this being due to the establishment of
at least a partial vacuum in the flask during inhalation with the
bores 10 and 11 closed. Further, since there is this additional
outside air intake source, instead of only partially filling the
bowl, one can place considerably more smoking material or substance
in the bowl, light it briefly, leave the finger or fingers off the
bores after an inhalation and pass the smoking pipe along to
another person to allow them to smoke it.
Thus, with the additional stopper and its air intake bores, the
pipe can be smoked in the same manner as a regular pipe, i.e.,
puffed on. Further, if desired, once the substance being smoked
enters the water in the flask, the removal of the index finger from
the air intake bores can allow the smoke to be drawn into the lungs
in one large inhalation.
The amount of air entering the bores 10 and 11 can be regulated by
varying the pressure of the finger applied thereover, i.e., placing
the under surface of the finger closer to or tight against the
intake end of such bores or by slightly spacing the finger from
such bores, as distinguished from completely removing the finger
from stopper 9.
In the known devices of the water pipe concept in which the bowl is
directly above the water chamber and communicates therewith via a
pipette or tube, the smoke is drawn into the lungs more gradually
based on how much air can enter through the orifice in relation to
the quantity of smoking material or substance initially placed in
the bowl.
