  • Patent number: 4763567
    Abstract: A corn popper includes a vessel open at the top, and a removable top cover. A handle integral with the cover includes a pistol grip portion relatively remote from the vessel when the cover is attached. A stirring mechanism, supported for rotation about a vertical axis within the vessel when the cover is attached, rotates responsive to the squeezing of a trigger mounted slidably with respect to the pistol grip section of the handle. The means for driving the stirring mechanism include a drive gear angularly fixed on the stirring mechanism, and a pinion movable linearly into and out of driving engagement with the drive gear, and also rotatable, by virtue of an extension of the trigger.

The elongated, substantially cylindrical member is an integral member with a foot at its distal end. A plastic cap is snugly inserted into the top cover and has a bore having a diameter that is slightly larger than the diameter of the elongated, substantially cylindrical member which is concentric to the hole in the top cover and through which the elongated, substantially cylindrical member is slidably inserted.
