Abstract
Abstract An electrical device for the noncombustion utilization of tobacco and other smoking materials. The device consists of a canister or other appropriate container within which air is electrically heated to an appropriate temperature for volatilizing the desired components of smoking material previously inserted into a receptacle provided in the mouthpiece part of this invention. Volatilization takes place when the heated air is drawn through the smoking material contained in the mouthpiece assembly. The mixture of heated air and volatilized smoking material components is then drawn from the mouthpiece into the mouth and respiratory passages of the user of the device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
214 words
In an arrangement for utilizing tobacco and the like smoking materials without effecting combustion thereof, a side and bottom wall means defining a casing, said side wall means having openings therein adjacent the bottom wall means, a tubular chamber suspended within said casing and supported by said casing, said chamber being open at its lower end, heating means within said chamber for imparting heat to air entering the same through said openings and said open lower end, a tubular conduit in communication with the upper end of said chamber, a tubular mouthpiece means, an apertured tubular smoking material container removably arranged within one end of said mouthpiece means and having a length such as to protrude therefrom, said container being dimensioned such as to telescopically fit within said tubular conduit whereby to communicate air heated in the aforementioned chamber through said container to the mouth and respiratory passages of the user by way of the mouthpiece-contained smoking material; the heat energy in the heated air being imparted by convective and conductive transfer mechanisms to the smoking material wherefrom the volatile ingredients are evaporated away from the nonvolatile cellulosic components of the smoking material and are thence carried as a vapor in the heated air stream to the mouth and respiratory passages of the user.

Claim 3
Dependent Claim
21 words
The arrangement as claimed in claim 1 wherein said heating means comprises an incandescent light bulb supported within said suspended chamber.
Claim 4
Dependent Claim
43 words
The arrangement as claimed in claim 1 and further including air valve means operably associated with said mouthpiece means up stream of said smoking material container and operable to admit cool air to admix with the heated air flowing through said mouthpiece means.
Claim 5
Dependent Claim
29 words
The arrangement as claimed in claim 1 and further including handle means extending from said casing permitting the user to handle and move said arrangement without contacting said casing.
Claim 6
Dependent Claim
20 words
The arrangement as claimed in claim 1 and further including latch means to hold said container within said mouthpiece means.
