  • Patent number: 6014977
    Abstract: A curling iron includes a handle that supports a heating element that projects out from the handle. An adjustable barrel is also carried by the handle and surrounds the heating element such that the heating element is substantially centrally disposed in the barrel. The barrel is adjustable between first and second positions where the diameter of the barrel is larger in the second position than the first position. The heating element remains centrally disposed in the barrel in the first and second positions. The barrel is adjusted by moving the clip assembly that is connected to the barrel. The clip assembly includes a clip that accommodates the changes in barrel diameter. A plurality of support elements are connected to the handle and adjustably support the barrel. The support elements include springs that support shoes that slidably engage the barrel.
