Abstract

Abstract An apparatus for projecting a light beam is disclosed which is constructed so as to simulate a gun. Within the apparatus a light bulb is mounted upon a base having a spherical surface. This base is resiliently engaged by a bearing having a correspondingly shaped interior in such a manner that the position of the bulb may be adjusted slightly so that the filament of the bulb is correctly positioned relative to a lens used in projecting a light beam. In the apparatus the bulb and the lens are separated by a shutter mechanism. The apparatus includes a trigger which, when actuated, first closes a switch to supply electric power to the light bulb and then causes the release of a shutter actuator serving to move the shutter so that it opens and closes within a comparatively short time interval.
