US Pat 4,530,112 1985 Jul; :1-4
A combined headpiece, light source, and protective face shield. The orienion of the emitted light beam from the light source remains the same whether the face shield is in a down protective position or a raised unprotective position for the user's face. This allows the user to use both hands while at the same time having the beam directed forward to illuminate the environment. A hinge and bracket assembly joining the face shield to the light source allow the source to maintain its desired orientation. A flexible power supply lamp cord rigidly attached to the headpiece supplies a retaining force to the lamp and its attached hinged bracket to act to maintain it in its moved position. Although this invention has application to many different types of end uses, its preferred embodiment was primarily designed and constructed for use by miner's underground.
