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 compact, disposable-type flashlight which is particularly suited to be carried on one's person, in a briefcase or purse, has a hollow, oval shaped case. Caps cover ends of the case with a bulb carried in one cap. The bulb extends into the case where a base of the bulb engages an end wall of a resilient member. The resilient member in turn separates a pair of batteries which have an insulated and uninsulated outer casing respectively. A conductive strap fits about the casings to join the batteries to the resilient member. The batteries are opposingly positioned allowing a conductive plate in the other cap to connect opposite terminals of the batteries in series. A pair of lead wires extend from the bulb base with one wire connected to the positive terminal of the insulated battery while the other lead wire is free and extends into a space between the case and the strap. To activate the flashlight the case is manually squeezed to force the free lead wire to contact the strap.

A pressure-activated light source in the form of a bulb, a battery and a spring for maintaining the bulb and battery spaced from one another is positioned in a closed end of the housing and adapted to be activated when a finger inserted into the housing forces the battery against the contact of the bulb.

Abstract: The simple switch of a small pocket flashlight consists of a single spring wire conductor extending from the center post positive terminal diagonally downwardly across the insulating body separating the two cells toward the uncovered metal can negative terminal of the other cell. When pressure is applied through the flexible nonconductive flashlight jacket, the wire conductor is brought into contact with the metal can negative terminal of the other cell to close the series circuit through the cells and lamp. In opening and closing the switch, bending of the wire conductor is limited to the portion remote from the positive terminal contact end by a fulcrum formed by a bend in the wire and engaging the insulating body between the two cells.

When applied over the barrel of the flashlight, the vinyl sleeve provides a non-abrasive but slip-resistant surface for gripping. The inside diameter of the sleeve is less than the outside diameter of the barrel of the flashlight, and a household detergent is used as a lubricant to facilitate slipping the sleeve onto the barrel of the flashlight.

Abstract: A disposable flashlight includes a battery and bulb within a casing, a conductive clip engaging the battery and extending through an elongated peripheral slot in the casing, and a conductive member engaging a terminal of the light and extending into proximity with the end of the clip so that the end of the clip can be pushed through a contact opening in the casing into electrical contact with the conductive member to turn the light on. The peripheral slot extends a sufficient distance along the circumference of the casing so that the clip can be rotated within the slot to an "off" position in which its end no longer overlies the contact opening within the casing. In that position, the light cannot be activated when pressure is applied to the clip.

Abstract: A flashlight having side by side compartments for storage and a battery respectively. The battery compartment has partial dividers for confining the battery and leaving a space for a contact strip having a leg portion on which the battery sits. A snap in divider fits above the battery to hold a lamp, and the top of the contact strip is bent inwardly to make contact with the base of the lamp. Different color light transmitting caps can be put over the lamp so that the flashlight can be used for spectator voting or approval. Preferably different color caps can be kept in the storage compartment.

Abstract: A disposable, floating electric flashlight that glows in the dark and is illuminated by merely squeezing the flashlight casing. Any external switch actuator passing through the flashlight casing is thereby eliminated facilitating buoyancy. When the flashlight is illuminated, phosphorescent material within the internal walls of the flashlight casing is regenerated to cause the flashlight to glow in the dark. If the flashlight is accidentally dropped into water, the lamp is balanced to float the flashlight in a predetermined orientation to enable the glowing light to be quickly retrieved.

Abstract: This disclosure pertains to a flashlight housing having a corrugated flexible end adjacent the lamp and reflector opening. A cap at the other end, when removed permits the inclusion of the battery within the housing. The center pole of the lamp and one end of a conducting strip is urged into contact with the opposed terminals of the battery by the bias forces exerted by the corrugations in the case upon the lamp and reflector associated therewith. The other end of the conducting strip may be forced into electrical contact with the other pole of the lamp, by way of the non-reflecting side of the reflector when a portion of the corrugations are manually depressed inwardly, thereby energizing the lamp.

Abstract: This invention relates to a flashlight (1) that may be seen in the dark, (2) which carries a universal mounting on one external wall, and (3) an internal switch adjacent the opposite wall which is elastic and which on pressing will close the switch. By mounting the flashlight above, for example, a keyhole, the flashlight can be seen, and when the outer wall is pressed, the keyhole is illuminated. Moreover, the light bulb within three or four seconds restores the phosphorescent band to luminosity, (reactivation chamber) because part of it is located in a regenerative phosphorescent chamber so that it performs not only the normal lighting function, but regenerates the phosphorescent material on the chamber walls as well. The phosphorescent material, a zinc sulphide or zinc-cadmium sulphide (harmless) has a persistence of glow of two to twelve hours.

Abstract: A globular chemical-lighting assembly suitable as an illuminated playing ball or as an omnidirectional light-emitting source. The assembly is constituted by a compact chemi-luminescent device which is insertable within an inflatable globe formed of translucent material to occupy a central position therein, the globe acting to uniformly diffuse the light emitted by the device. The chemi-luminescent device is formed by two separate chambers in side-by-side relation, each containing one component of a two-component chemi-luminescent system and a manually-operated activator interconnecting these chambers to intermingle the components and thereby cause a light-producing reaction, the device normally being in a non-reactive state.
