a [Q 2O I9 is COMPACT WATER PIPE BACKGROUND OF THE INVENTION This invention relates generally to a smoking device, and more particularly to an improved liquid filtered smoking device which is portable, readily adaptable to cleaning, and particularly useful in connection with the smoking of rare and expensive tobaccos.
Prior art water pipes usually 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 large, bulky and quite difficult to maintain and clean, and they 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.
Yet an additional object of this invention is to provide a smoking device which is uniquely well suited for the purpose of smoking rare and expensive tobaccos.
Another object of this invention is to provide a smoking device that is portable and readily adaptable to efficient shipment in bulk.
An additional object is to provide a water pipe that will not spill water when tilted or caused to fall on its side.
Still another object is to provide a water pipe which can be used in conjunction with various sizes of liquid compartments to change the volume of filtering fluid at the users option.
Yet another object of this invention is to provide a smoking device having a unique reversible bowl which is capable of retaining a smaller or a larger amount of smoking tobacco at the users option.
SUMMARY OF THE INVENTION Briefly, in accordance with this invention, a compact water pipe is provided which comprises a first hollow elongated tube having top and bottom open ends, closure means secured across the bottom end to permit fluid to be retained in the tube, a second hollow elongated tube having top and bottom ends, said bottom end being inserted into the first tube and the top end extending outwardly therefrom, and a reversible smok' ing bowl connected to the top end of the second tube for retaining smoking tobacco and permitting smoke to pass into the tube. A top closure cap is provided for the open end of the first tube to prevent fluid from spilling in the event the tube is tilted or caused to fall on its side. A plurality of holes within the top closure cap enables the user to draw smoke therethrough without removing the cap.
As the smoking tobacco is burned, smoke passes through an orifice in the reversible smoking bowl and into the second tube, and continues down into the fluid.
The user of the device draws air at the open end of the first tube, thereby creating a partial vacuum and caus' ing the smoke to filter through the fluid and be drawn up into the first tube, whereby it is inhaled by the smoker. The water pipe is adapted to fit into a conventional fish bowl in order to increase the volume of filtering fluid, as will be hereinafter explained in greater detail.
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. 1, thewater pipe of the present invention is illustrated generally by the numeral 10. A first hollow cylindrical tube 15 is provided with top open end 17 and bottom open end 16 which is provided with closure cap 12 secured thereacross to permit fluid 13 to be retained within the tube. A second hollow elongated tube 18, having a bottom open end 19 and a top open end 29, is inserted diagonally into the first tube and secured therein.
Liquid 13, which may be any suitable filtering liquid such as water, wine, or other liquid as desired, is retained within the tubes and comes up to the liquid level line 14. The location of liquid level line 14 is at the users option and need not be precisely specified. It is important, however, that bottom closure cap 12 provide a secure and liquid tight'seal across open end 16 of tube 15 in order to retain liquid therein. This can be achieved by use of a conventional. plastic or rubber cap which is designed to fit snugly across the bottom of the tube as shown.
Smoking bowl 20 is adapted to fit directly over open end 29 of tube 18, and smoking compartment 24 of bowl 20 is designed to receive the smoking tobaccos.
Located across the top open end 17 of tube 15 is an additional closure cap 11 having a plurality of holes 27 therethrough. Cap 11 is also designed to fit snugly across the open end of the tube: so as to retain fluid therein. The holes 27 are designed to be in the center of closure cap 11 such that in the event that the device 10 is tilted or caused to fall on its side, the liquid 13 would not come up to a sufficiently high level so as to emerge through holes 27.
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 holes 27 of open end 17 (or he may remove cap 11 and place his mouth directly over openend 17) and draws thereupon so as to create a partial vacuum in region 26 of tube 15. Smoke from the burning tobacco will be drawn through orifice 25 and will continue down through tube 18 and into liquid 13 by virtue of open end 19 of tube 18. The smoke then filters through the liquid 13 and continues upward into cylindrical tube 15, passing through liquid level line 14 and continuing upward until it reaches the users mouth.
If a greater amount of filtering fluid is desired, bottom closure cap 12 can be removed and the entire device 10 may be inserted directly into the open end of a conventional fish bowl. A suitable air tight and rubber like retaining piece may be provided to maintain the device rigidly within the fish bowl. In this way, the volume of the fish bowl would permit a substantial increase in the amount of retained liquid, which would in turn provide more filtering to the smoke. Naturally, different size fish bowls would provide a variety of filtering media.
This new pipe arrangement is particularly efficient in that all of the smoke created by burning the tobacco in compartment 24 ultimately ends up in region 26 of tube 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 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 a sufficient diameter to permit smoke to pass therethrough while being capable of retaining the smoking tobaccos. Orifice 25 is large enough to permit ashes to fall through, thus clearing an air passage which tends to mellow the smoke. The bowl, which is preferably made of aluminum or other suitable material, is designed to fit snugly over the open end of cylindrical member 18, as illustrated in FIG. 1. It should be apparent that either compartment 24 or 28 can be made to slip over opening 29 of member 18, and that in eitherevent, the appropriate remaining compartment becomes a smoking compartment. Thus, a single unitary device is capable of providing 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. Another use of this reversible bowl is disclosed in my copending application, Ser. No. 357,186, filed May 4, 1973.
Referring again to FIG. 1, it will be apparent that the smoking device is quite simple to maintain and to keep clean. Thus tube 18 can easily be removed from tube 15 and smoking bowl 20 can easily be removed from the tip of tube 18. In this way, all component parts of the water pipe can be placed inside of the large tube 15 during storage or during bulk shipment, thereby enabling the device to be efficiently stored and/or shipped.
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 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. As previously noted, the entire device can be inserted into a conventional bowl, such as a fish bowl, so as to significantly increase the volume of filtering liquid 13. This arrangement is fully illustrated in applicants co-pending application. Again, the device is designed so as to virtually eliminate the possibility of liquid spillage. Closure caps 11 and 12 fit snugly over tube 15 so as to prevent any liquid spillage. Holes 27 are designed to be in the center portion of closure cap 11 such that the liquid level line 14, in the event of a tilting of device 10, would still not rise sufficiently high so as to pass through these holes. Indeed, accidental water spillage is virtually eliminated.
Other appropriate and suitable modifications can be made to the structure of this device without departing from the spirit and scope of the inventive concept claimed herein. Thus, reversible smoking bowl 20, as well as closure caps 11 and 12, can be adapted to fit over the appropriate open ends in any of a number of well known ways such as the use of bayonet mounts, conventional screw threads and simply slip on techniques. The same principle applies with respect to the insertion of cylindrical member 18 within member 15. During storage or shipment, tube 18 as well as reversible how] 20 are removable from the angular position shown in FIG. 1 and will easily fit within the larger tube 15. t
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 portable as well as readily adaptable to cleaning and efficient maintenance.
