Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 199 words
A tobacco smoking pipe holder and dryer comprising an outer housing enclosing a pipe-receiving chamber and having an enlarged unobstructed front opening for unobstructively receiving a pipe and having other openings for admission of air thereto, means to support a pipe with its bowl positioned upwardly in said chamber, blower means positioned in said housing for circulating air therein, an inner housing supported in spaced relation to said outer housing and having an inlet and an outlet end, said outlet end comprising at least opening positioned to direct the flow of heated air downward against the interior of the bowl of a pipe supported by said supporting means in said outer chamber housing, said blower means being positioned in said inlet end and operable to receive air from said air admission openings, electric heating means positioned within said housing within said inner housing to heat air circulating therethrough, switch means controlling energization of said blower means, switch means controlling energization of said heating means and operable to energize the same only when said blower switch means is closed, and thermostatic switch means operable to de-energize said blower means upon occurence of a predetermined temperature in said air-directing inner housing.
Claim 2
Dependent Claim 199 words
A tobacco smoking pipe holder and dryer comprising an outer housing enclosing a pipe-receiving chamber and having an enlarged unobstructed front opening for unobstructively receiving a pipe and having other openings for admission of air thereto, means to support a pipe with its bowl positioned upwardly in said chamber, blower means positioned in said housing for circulating air therein, an inner housing supported in spaced relation to said outer housing and having an inlet and an outlet end, said outlet end comprising at least opening positioned to direct the flow of heated air downward against the interior of the bowl of a pipe supported by said supporting means in said outer chamber housing, said blower means being positioned in said inlet end and operable to receive air from said air admission openings, electric heating means positioned within said housing within said inner housing to heat air circulating therethrough, switch means controlling energization of said blower means, switch means controlling energization of said heating means and operable to energize the same only when said blower switch means is closed, and thermostatic switch means operable to de-energize said blower means upon occurence of a predetermined temperature in said air-directing inner housing.
