2.. An induction heating coil comprising a plurality of turns electrically connected in series and lying in parallel planes, each coil having a portion flared outwardly to lie in a plane substantially perpendicular to said parallel planes whereby a pocket is formed Within the turns of the coil for receiving an object extended perpendicularly to the longitudinal axis of said coil.

3. An induction heating coil comprising a plurality of turns electrically connected in series and having an elongated transverse axis, the

turns being formed to have one end flared outwardly from the plane of the main portion of the turns to lie in a plane substantially perpendicular to the plane of the main portion of the turns whereby a pocket is formed within the coil.

4. An induction heating coil comprising a plurality of turns electrically connected in series and having an elongated transverse axis, some of said turns having a portion at one end flared outwardly in one direction and the other turns having a portion at the same end flared outwardly in the opposite direction so that said flared portions are oppositely disposed and provide an opening to receive within said coil an object extended perpendicularly to the longitudinal axis of said coil.
