Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
151 words
In a mechanical smoking device, a. wall structure comprising top, bottom, and side walls defining a storage chamber containing liquified gas, b. a refill valve mounted in said bottom wall structure and operable to pass liquified gas under pressure into said storage chamber, c. a discharge valve mounted in said top wall structure and operable to discharge gas in its gaseous state from the storage chamber, and including an operating plunger, d. wall structure defining a suction chamber that communicates with said storage chamber via said discharge valve, e. a cap adjustably mounted on the wall structure defining the suction chamber and having an end wall formed with openings, f. a stem carried by said cap for operative engagement with said plunger, and g. openings in said cap and the wall structure on which it is mounted which, when in alignment, establishes communication between said suction chamber and the ambient atmosphere.
