3 Claims, 2 Drawing Figures l SMOKING Device BACKGROUND OF THE INVENTION This invention relates generally to a smoking device, and more particularly to an improved liquid filtered smoking device whichis readily adaptable to cleaning and is particularly useful in connection with rare and expensive smoking tobaccos.
Prior art water pipes are generally well known, however, such water pipes generally suffer from the disadvantages that they consist of one or more flexible hoses which have a great tendency to get clogged up as a result of the smoke which passes therethrough. Such prior art water pipes are quite difficult to clean and must often be completely discarded after extensive use. Additionally, such pipes are unsanitary, complicated in their construction and extremely inefficient when it is attempted to use such pipes for the smoking of rare and expensive tobaccos.
It is, therefore, a primary object of this invention to provide a new and improved smoking device which avoids all of the above-mentioned disadvantages.
An additional object of this invention is to provide a smoking device which is easy to clean and for which replacement parts can be readily had.
Still another object of this invention is to provide a smoking device which is sturdy and rugged in its construction. I
Yet an additional object of this invention is to provide a smoking device which is well suited for the purpose of smoking rare and expensive tobaccos.
Yet another object of this invention is to provide a smoking device having a reversible bowl which is capable of retaining a smaller or a larger amount of smoking tobaccos at the users option.
SUMMARY OF THE INVENTION Briefly, in accordance with this invention, a smoking device is provided which comprises a large chamber for maintaining a volume of fluid, a first substantiallycylindrical member having two open ends and being inserted into the chamber and extended into the fluid, a second substantially cylindrical member also having both open ends and also inserted into the chamber and extending into the fluid, and a reversible smoking bowl which is adapted to fit over an open end of the first cylindrical member and contains the smoking tobacco. As the smoking tobacco is burned, smoke passes through an orifice in the smoking bowl and into the first cylindrical member, and continues down into the fluid. The user of the device draws air at the open end of the second cylindrical member, thereby creating a partial vacuum and causing the smoke to filter through the fluid and be drawn up into the second cylindrical member, whereby it is inhaled by the smoker. An orifice is provided along the second cylindrical member which enables the user, at his option, to permit air to be drawn into this member and to mix with the smoke, thereby creating a milder smoking mixture.
DESCRIPTION OF THE EMBODIMENT The specific nature of the invention as well as other objects and advantages thereof will clearly be apparent from the following description and the associated drawings.
FIG. 1 illustrates a cross sectional view of a smoking device substantially in accordance with this invention.
FIG. 2 shows a cross sectional view of the reversible bowl for use in accordance with this invention.
Referring more particularly to FIG. I, the smoking device of the present invention is illustrated generally by the numeral 10. Chamber ll, shaped somewhat like a conventional fish bowl, is provided with a flattened base portion 12 and adapted to contain a liquid 13. This liquid may be any suitable filtering and cooling liquid such as water, however, other liquids such as wine may also be utilized. Inserted into chamber 11 is a substantially cylindrical pipe-like member 15 which is secured within chamber I I by means ofa cylindrical flexible rubber-like piece 23 which. by means of friction and pressure, retains cylindrical member I5 in a desired position with respect to chamber II. Cylindrical member 15 extends sufficiently into chamber 11 such that open end 16 is sufficiently below the liquid level line 14. The other open end 17 of cylindrical member 15 extends outwardly from chamber 11.
A second substantially cylindrical member 18, having open ends 19 and 28, also extends into chamber 11 such that open end 19 is below liquid level line I4. Smoking bowl 20 is adapted to fit directly over open end 28' of cylindrical member 18, and smoking compartment 24 of bowl 20 is designed to receive the tobacco materials.
In operation, the smoking tobacco is placed within compartment 24 of smoking bowl 20 and is lit by the user. Simultaneously, the user places his mouth over open end 17 of member 15 and draws thereupon so as to create a partial vacuum in the tube 26 of member 15. Smoke from the burning tobacco is drawn through orifice 25 and continues down through cylindrical member I8 and into the liquid 13 by virtue of open end 19 of cylindrical member 18. The smoke then filters through liquid 13 and continues upward into cylindrical member 15, passing through liquid level line 14 and continuing upward until it reaches the users mouth.
During this initial drawing period, the user maintains orifice 22 closed by means of his thumb or other appropriate means to prevent air from being drawn into the tube. Once a sufficient amount of smoke has been drawn into section 26 of member 15, the user may, at his option, permit air to be drawn in through orifice 22 and to mix with the smoke in member 15 so as to create a milder and mellower smoke mixture. This smoking pipe arrangement is particularly efficient in that most of the smoke created by burning the tobacco in compartment 24 ultimately ends up in area 26 of cylindrical member 15 and is entirely, at the option of the user, drawn into the users lungs. Accordingly, little or no smoke is wasted into the atmosphere as is the case with prior art inefficient pipes.
Referring now to FIG. 2, the details of reversible bowl 20 will be described. Reversible bowl 20 comprises essentially of a first smoking compartment 24 having an inside diameter D and a second smoking compartment 28 also having the same inside diameter D. The two smoking compartments are connected by an orifice 25 having the sufficient diameter to permit smoke to pass therethrough while being capable of retaining the smoking tobaccos and thereby avoid the necessity of a conventional screen. The bowl, which is preferably made of aluminum or other suitable material, is designed to fit snugly over the open end 28 of cylindrical member 18, as illustrated in FIG. 1. It should be appparent that either compartment 24 or 28 can be made to slip over opening 28' of member 18, and that in either event. the appropriate remaining compartment becomes the smoking compartment. Thus. a single unitary device is capable ofproviding the user with two separate smoking bowls each having the same diameter but each having a different length (D or D such that a different amount of smoking tobacco may be utilized with the same smoking pipe. A similar use of the reversible bowl is disclosed in copending US. patent application, Ser. No. 364,065. filed May 25, 1973.
Referring again to FIG. 1, it will be apparent that the smoking device is quite simple to maintain and to keep clean. Thus. cylindrical member can easily be removedfrom chamber 11 and smoking bowl can easily be removed from the tip of cylindrical member 18. For use in operation. cylindrical member 18 is maintained at an acute angle with respect to the vertical orientation of cylindrical member 15. This arrangement is. however, merely exemplary, and it will be understood that the functions and orientations of the cylindrical members need not be precisely as shown in the attached drawing. Thus, appropriate interchanges would be well within the ability of persons having ordinary skill in the art. The cylindrical members 15 and 18 as well as the chamber 11 are preferably made of transparent material such as glass or suitable transparent plastics so as to enable the user to determine readily the level of liquid and smoke contained therein.
Other appropriate and suitable modifications can be made to the structure of this invention without departing from the spirit and scope of the invention claimed herein. Thus. reversible smoking bowl 20 can be adapted to fit over open end 21 of cylindrical member 18 in any of a number of well known ways, including the use of bayonet mount. conventional screw threads. simple slip-on and other well known techniques. The same applies with respect to the insertion of cylindrical member 15 within chamber 11. Any well known and appropriate securing of member 15 within chamber 11 would be within the spirit and scope of this invention.
It should be apparent from the foregoing that a new and improved smoking device has been provided which is uniquely suitable for smoking rare and expensive tobaccos and which is readily adaptable to cleaning and efficient maintenance.
