Abstract
An electric oyster knife has a case (1), a blade holder (12) with a blade (13) slidably longitudinally between outer and inner positions with respect to the case, an electromagnet (2) mounted in the case for oscillating the blade holder between its two positions. An armature (7) is pivotally mounted in the case. The armature has a cam surface (11) for driving the blade holder toward its outer position, in a first position of the armature, and for allowing the blade holder to move to its inner position, in a second position of the armature.
Claims7
An electric oyster knife comprising a case, a blade holder slidable between inner and outer positions with respect to the case, said blade holder being adapted to hold and retain an oyster knife blade, electromagnetic motor means in said case to vibrate the blade holder and a blade held thereby between the inner and outer positions, said electromagnetic motor means comprising an electromagnet in said case, an armature in said case mounted for pivotal movement about an axis, relative to said electromagnet, a cam surface on said armature, said armature being pivotally movable between a first position in which the cam surface drives the blade holder to said outer position, and a second position in which the blade holder can return to said inner position.
