Lewis' patent dining table "is principally manufactured of mahogany or other suitable wood and of any required form and dimensions much in the same manner as ordinary dining tables are made. The difference between them and it consists in a shallow receptacle or chamber for containing heated air which chamber is from 2 to 4 more inches in depth; but its length and breadth are coextensive with the length of the table. The top of which forms the cover which is of wood with a great number of large openings to allow the hot air to act upon the metallic covering which is laid smoothly over the whole length and breadth of the table." (Patent Number 4,207)
Only the cap of the model remains.
