Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
174 words
A tubular water pipe comprising: a base structure comprising a first chamber containing an organic material burning unit, a second inhalation and water chamber connected at one end to said first chamber in axial alignment therewith, means separating in water tight arrangement said first and second chambers, means between said first and second chambers containing a one-way valve for transferring gas created by the burning of the material in said first chamber into said second chamber, an organic material burning unit mounted in said first chamber, said burning unit comprising an electric heating element and a bowl in heat transfer relationship, said bowl being provided for holding the material to be burned, an electric switch means mounted on said water pipe and connectable to an electric source for selectively energizing said heating element, and a mouthpiece mounted on the other end of said second chamber, whereby suction applied by a smoker to the mouthpiece draws gases of the burning material passing through said one-way valve and the water into the mouth of the smoker.
Claim 2
Dependent Claim
174 words
A tubular water pipe comprising: a base structure comprising a first chamber containing an organic material burning unit, a second inhalation and water chamber connected at one end to said first chamber in axial alignment therewith, means separating in water tight arrangement said first and second chambers, means between said first and second chambers containing a one-way valve for transferring gas created by the burning of the material in said first chamber into said second chamber, an organic material burning unit mounted in said first chamber, said burning unit comprising an electric heating element and a bowl in heat transfer relationship, said bowl being provided for holding the material to be burned, an electric switch means mounted on said water pipe and connectable to an electric source for selectively energizing said heating element, and a mouthpiece mounted on the other end of said second chamber, whereby suction applied by a smoker to the mouthpiece draws gases of the burning material passing through said one-way valve and the water into the mouth of the smoker.
Claim 3
Dependent Claim
32 words
The tubular water pipe set forth in claim 1 wherein: said first chamber comprises two detachable coaxially arranged parts which may be separated to expose said bowl for loading and cleaning purposes.
Claim 4
Dependent Claim
23 words
The tubular water pipe set forth in claim 2 wherein: said two parts comprise frustums of like cones interconnected at their widest ends.
Claim 5
Dependent Claim
25 words
The tubular water pipe set forth in claim 1 wherein: said heating unit is threaded into said base structure and extends into said first chamber.
Claim 6
Dependent Claim
26 words
The tubular water pipe set forth in claim 1 wherein: said electric switch means being in a normally open position and mounted on the base structure.
Claim 7
Dependent Claim
22 words
The tubular water pipe set forth in claim 1 wherein: said first chamber comprises an air inlet port adjacent said burning unit.
Claim 8
Dependent Claim
25 words
The tubular water pipe set forth in claim 1 wherein: said base structure, first and second chambers and said mouthpiece are all in axial alignment.
Claim 9
Dependent Claim
37 words
The tubular water pipe set forth in claim 7 wherein: said burning unit is mounted outside of said first chamber, and means for connecting the gas of said material to substantially the bottom of said first chamber.
Claim 10
Dependent Claim
41 words
The tubular water pipe set forth in claim 1 wherein: said one-way valve comprises a pair of resilient fingers normally biased together to close the valve and moveable apart to open the valve upon gas being generated in said burning unit.
Claim 11
Dependent Claim
43 words
The tubular water pipe set forth in claim 1 wherein: said valve comprises a resilient sheet-like member biased to normally close said valve and when actuated by suction of a smoker deflects under the pressure of the gas thereagainst to open said valve.
Claim 12
Dependent Claim
16 words
The tubular water pipe set forth in claim 1 wherein: said heating element supports said bowl.
