Abstract
A device for heating tables containing an evaporable substance such as scents, deodorizers or insecticides includes an elongated heating support of insulating material having a planar surface and a longitudinal opening therethrough. The heating support is preferably T-shaped, the planar surface being the top of the T. The planar surface is coated with an enamel coating so that residue from the evaporable substances is easily removed. A cylindrical resistance heating element is inserted into the cylindrical opening, the cylindrical element being of a lesser length than the length of the heating support. The arm portions of the T-shaped support may be each provided with a longitudinally extending hole for limiting lateral transfer of heat through the support. Conductors for supplying electricity to the heating element enter the cylindrical opening at a point displaced from the outward edges thereof so that the outward edges of the heating support member is completely insulated. The heating support member with the cylindrical resistance heating element installed is preferably mounted within a nonconductive housing. The conductors of the heating element are preferably connected to electrical connection means such as a plug member associated with the housing in which the heating support member and heating element are mounted.
