Abstract
Abstract A frying apparatus includes a support housing, an open top fat container, heating means for heating the fat in the container, and an escutcheon mounted above and behind the fat container. A thermostat, mounted in the escutcheon, is operatively connected to the heater for controlling energization of the heater. An electric motor unit is operatively connected to the thermostat for adjusting the setting of the thermostat upon energization of the motor. There is a circuit for connecting the motor unit to a suitable source of electric energy, including a manually operable switch. The switch is mounted in the housing forward of the open fat container.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
A frying apparatus comprising: a. a rigid support housing; b. an open top fat supported in said housing and container arranged to receive food for cooking in the fat; c. heating means for electric heating the fat in said fat container, d. an escutcheon mounted above and behind said fat container; e. thermostat means mounted in said escutcheon and operatively connected to said heating means for controlling energization of said heating means; f. an electrically energizable motor unit operatively connected to said thermostat means for adjusting the setting of said thermostat means upon energization of said motor unit; and g. an electrical circuit for connecting said motor unit to a suitable source of electric energy, said circuit including manually operable electric switch means for selective energization of said motor upon actuation of said switch means; h. said switch means being mounted in said housing forward of said open top fat container.
