Abstract
An armature apparatus includes a first tine member, a second tine member, a center tine member, and a connecting portion. The connecting portion is coupled to the first tine member, the second tine member, and the connecting portion, and the connecting portion has a line of symmetry. The center tine member is attached to the connecting portion along the line of symmetry such that approximately one half the area of the connection portion is above the center tine member and approximately one half the area of the connection portion is below the center tine member. The attachment is effective to prevent a formation of a horizontal force in the center tine member along the third length when a vertical force is applied to the center tine member in the direction of third thickness.
