Abstract: An electric lantern has a case in two portions which may be opened to permit replacement of batteries without disengagement of the other components from the upper portion of the case. Means are provided to retain the lamp and upper portion of the battery case as retained members of a structurally engaged assembly which may be disengaged from the lower portion of the battery case. As a separate feature, a lens may be disengaged from the battery case to permit replacement of the electric lamp without opening the battery case. A rod is used as a member of the engagement means which hold the lantern components together; in addition, the rod may be part of the lantern''s electrical circuit. The electrical circuit may be designed so that it is opened when the battery case is opened and/or when the lens is disengaged from the battery case.
