Abstract: A flashlight comprises a battery housing component and a lamp housing component, both with peripheral walls of elliptical cylindrical shape having, respectively, the same major and minor diameters, and terminating at one end, respectively, in a circular edge that lies in a plane that is oblique to the axis of the cylindrical wall by a selected angle A and includes a major diametrical chord of the ellipse of the walls. The minor diameter of the ellipse of the peripheral walls of each component is equal to the cosine of the angle A times the major diameter. The housing components are joined together with their circular edges meeting for rotation of the lamp housing component on the battery housing component, thereby permitting adjustment of the direction of the light beam relative to the axis of the battery housing component.

Abstract: A variable-width-beam light apparatus is provided having a lamp and reflector assembly in which a lamp is supported for selective axial displacement along a longitudinal optical axis with respect to a focal point of the reflector to enable adjustment in the width or angle of divergence of an emitted beam of light. The lamp is selectively positioned by a rotatable knob carried by a lens of the assembly and positioned exteriorly at the front of the lens for operation. The rotatable knob connects with a shaft coupled by screw threads with a lamp engaging cylinder that is axially slideable in a tubular guideway such that rotational movement is translated to longitudinal movement to effect and control axial displacement of a lamp. The lamp is resiliently biased in a forward direction with respect to the lens.

Abstract: A portable flashlight comprises an elongate battery casing and a swivelling flashlight head connected to one end of the casing through a ball-and-socket connection which forms part of the electrical circuit connecting the batteries to the flashlight bulb. A removable support pad is provided for attachment to an end cap of the casing for supporting the casing in vertical position while permitting swivelling movements of the flashlight head, and the casing further includes a transversely extending support pad for supporting the casing on its side and a magnetic assembly for magnetically attaching the casing to a support surface.

Abstract: A headlamp device for bicycles and like vehicles, which includes a reflector, a bulb having its end fixedly inserted through an opening formed in said reflector, an illumination covering mounted on the front face of said reflector, and a battery casing attached integrally to the rear portions of these members. The improvement comprises an outwardly extending locking piece affixed to said end of said bulb, a cylindrical extension for the insertion of said end of said bulb provided to the rear edge of said opening in said reflector, and the rear periphery of said cylindrical extension being stepped to define locking portions differing in axial length, said locking portions being engaged within said locking piece, whereby, when said bulb is fixedly inserted into said opening in said reflector, said locking piece can selectively be locked onto said locking portions differing in axial length.

Abstract: A flexible flashlight which may provide light at any angle even in an environment in which the area in which to position a flashlight is extremely limited. A bellows is provided one end of which is threaded onto the body tube of a flashlight, the other end of which contains a bulb along with a lens and bezel. The bellows is made of a semi-rigid material so that once its curvature is formed it will remain fixed indefinitely until reformed by the user. The flexible flashlight may be placed on any flat surface or may be attached to any ferro-magnetic surface. In either case once the flashlight has been positioned both hands are free to perform work. An internal coiled helical cord is provided inside the bellows section to assure good electrical connection and to minimize the possibility of damaging the electrical pathway due to frequent flexion of the bellows.

Abstract: A book-light characterized by its small size and light weight is formed from suitable plastic material with a base supporting a vertical lamp-bearing arm and an integral clamp consisting of a U-shaped frame having side arms rigidly attached to the base and a central plate flexibly attached to the base so that the entire book-light may be attached to a book or other publication by inserting the cover or pages between arms and the central plate. The vertical lamp-bearing arm is mounted at one end in a transverse slot in the base, while the other end supports the lamp proper in a manner to permit both circular and vertical motions.

Abstract: A novelty toy in the shape of a skull includes a cranial shaped housing and a pivotal jaw portion. The jaw is biased to a closed position by a biasing element and includes a grip portion to be gripped by the user of the device to move the jaw to an open position. A depending handle is also defined on the skull to allow the skull to be supported by the user. A pair of lights are mounted in the eye apertures and reflectors are rotatably mounted within the apertures surrounding the lightbulbs. A gear train connects the reflectors to a manually operated gear to allow rotation of the reflectors within the housing. Each reflector includes a colored lens that may be rotated in front of the light to provide a different appearance to the toy. The lights are connected through a switch mounted within the housing to a portable power source. The switch includes a plurality of positions for producing alternate lighting or flashing effects.

Abstract: An aiming post light for artillery and mortar operations at night wherein an ordinary GI flashlight is converted with solid state circuitry to use a blinking light emitting diode (LED) as a light source, enabling ordinary flashlight batteries to last for months of constant use instead of the few hours life in use with previous post lights.

Abstract: In a pocket torch the bulb itself is used as the switch. It tilts between two positions of stable equilibrium, while being confined resiliently between the casing and the battery.

Abstract: A front body assembly and rear body assembly, hingedly connected together at their bottom and detented at their top for selective opening and closing, co-operate with each other to form a flashlight case assembly which receives and mounts a flashlight bulb and dry cell battery to thus provide a flashlight. A reflector assembly, carried by the front body assembly, is formed with a substantially annular reflecting surface disposed about a substantially annular transparent area which, in turn, surrounds an opening centrally disposed to receive a flashlight bulb when such bulb is positioned on a component mounting plate assembly carried by the rear body assembly.
