Abstract
Abstract The present invention is an apparatus for use at the dining table to provide a continuous supply of hot tortillas. An elongated housing has two openings in the top thereof with a first opening having a resistive heating element contained therein, and the second opening receiving a ceramic vessel therein. The ceramic vessel is maintained at an elevated temperature, either from the heat of the resistive heating element or from a separate heating unit. The ceramic vessel is basically cylindrical with an upper opening closed by a cover having a reservoir to receive water. The water is converted and transmitted as steam through passages in the cover to the inside of the ceramic vessel thereby helping maintain moisture content of the hot tortillas.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
226 words
An apparatus for providing a continuous supply of hot tortillas at a dining table comprising: an enclosed housing having an upper surface, a base, and walls, said housing having a pair of openings in said upper surface; first resistive heating means in a first of said openings and in a plane with said upper surface, said resistive heating means being larger in diameter than a normal tortilla; power means for connecting said first resistive heating means to a source of electrical power; ceramic vessel means in a second of said openings, said ceramic vessel means being generally cylindrical in shape with a cross section being larger in diameter than said normal tortilla; second resistive heating means in close proximity to said ceramic vessel means; means for connecting said second resistive heating means to said source of electrical power; cover means for said ceramic vessel means for closing an upper opening of said ceramic vessel means; mounting means for holding said ceramic vessel means in place; reservoir means in said cover means adapted for receiving water therein, passages from said reservoir to a bottom side of said cover means allowing steam from said reservoir to pass to an inside of said ceramic vessel means; and handle means connected to said cover, said handle means being removable for providing a conduit to said reservoir for adding water thereto.
Claim 2
Independent Claim
226 words
An apparatus for providing a continuous supply of hot tortillas at a dining table comprising: an enclosed housing having an upper surface, a base, and walls, said housing having a pair of openings in said upper surface; first resistive heating means in a first of said openings and in a plane with said upper surface, said resistive heating means being larger in diameter than a normal tortilla; power means for connecting said first resistive heating means to a source of electrical power; ceramic vessel means in a second of said openings, said ceramic vessel means being generally cylindrical in shape with a cross section being larger in diameter than said normal tortilla; second resistive heating means in close proximity to said ceramic vessel means; means for connecting said second resistive heating means to said source of electrical power; cover means for said ceramic vessel means for closing an upper opening of said ceramic vessel means; mounting means for holding said ceramic vessel means in place; reservoir means in said cover means adapted for receiving water therein, passages from said reservoir to a bottom side of said cover means allowing steam from said reservoir to pass to an inside of said ceramic vessel means; and handle means connected to said cover, said handle means being removable for providing a conduit to said reservoir for adding water thereto.
Claim 3
Dependent Claim
30 words
The apparatus as given in claim 1 comprising cylinder means inside said housing and below said second opening for receiving said ceramic vessel means therein in a close contiguous relationship.
Claim 4
Dependent Claim
19 words
The apparatus as given in claim 2 wherein said first resistive heating means is a solid, flat heating element.
Claim 5
Dependent Claim
26 words
