  • Patent number: 3975998
    Abstract: A pancake-making machine (for baking French-type pancakes or "crepes") has a drum rotatable by a drive motor via heat-resistant synthetic-resin gears on its ends. A transfer roller carried on a batter trough is displaceable toward and away from the drum by a handle which controls the drive motor to arrest both the drum and the transfer roller when the two are pulled apart. The transfer roller forms a layer of batter on the drum which is heated by an internal electric heating element supplied with current through axially extending copper sleeves at its ends. The handle is a bent wire pivoted at each end in a slot in the machine housing and latchingly engageable against the displaceable trough. A thermistor imbedded in the drum adjacent the surface thereof is connected via an electronic circuit to a triac in series with the heating element to control the drum heating. A wire stretched tight between two support arms serves to strip the baked pancake from the drum.
