Abstract
A housing contains electrical components that constitute a battery-operated smoke detector and alarm. Forming a part of the housing is a transverse wall that includes at least one opening. Adjacent to that one opening in one surface of the wall are a first succession of semi-cylindrical cavities each diametrically sized to seat a cylindrical battery. A support web is suspended from the wall in a position spaced from and opposite the opening with the wall-facing surface of that web including a second succession of semi-cylindrical cavities each diametrically sized to seat the battery and aligned with the respective cavity formed on the wall so as to captivate a battery therebetween. A cover member is matable with the wall so as to overlie the compartment in which the batteries reside. A lug depends from the cover for locking reception with an aperture formed in the transverse wall. An ear depends from the cover in a position to press against the battery when the cover is installed. Desirably, there are a space-opposed pair of such apertures, lugs and ears, together with a slot positioned in the wall in relationship to the battery opening so as to receive either of the ears when the …
