An armature apparatus includes a first tine member, a second tine member, a center tine member, and a connecting portion. The first tine member has a first length and a first width and these define a first surface. The second tine member has a second length and a second width and these define a second surface. The first surface generally faces the second surface and the first surface is generally parallel relation to the second surface. The center tine member has a third length and the third length is generally parallel to the first length and the second length. The connecting portion couples the center tine member to the first surface along the first length and to the second surface along the second length. The center tine member is generally disposed in a plane extending between the first tine member and the second tine member and the plane divides the first surface of the first tine member and the second surface of the second tine member.
