  • the electric lamps 24 may be exposed and replaced without rotating the rod and disengaging the upper and lower portions of the battery case.
  • a proper rotation of the knob and the rod causes the upper and lower portions 14 and 16 of the battery case 12 to be drawn together at their mating surfaces; a rotation of the knob 56 in the opposite direction will cause the two portions of the battery case to become disengaged while the hood, lens, and upper portion of the battery case remain engaged as members of assembly 29.
  • the structurally engaged assembly 29 may be engaged with or disengaged from the lower portion 16 of the battery case 12 to permit battery replacement by simply rotating the knob 56 while the nut 60 remains threaded onto the top of the rod 20.
  • FIGS. and 6 The electrical components and circuitry for the lantern shown in FIGS. 1-4, which utilizes lamps 24, are illustrated in FIGS. and 6.
  • Mounted onto the lower surface of disc 34 (not shown in FIG. 5) are four conductive members 62 which make contact with the terminals of the batteries 18 and connect the batteries when the upper and lower portions of the battery case 12 are in engagement with each other. With this feature the electrical circuit between the batteries and the lamps is opened when the lower portion of the battery case is disengaged from the upper portion of the case.
  • a pair of conductive wires 64 connect the terminals of the batteries with an inverter 68 situated inside the upper case portion 14 above the disc 34 where the electrical energy is converted from DC to high voltage AC.
  • the circuitry of the lamp includes a pair of switches 72 and 74, shown in FIGS. 1-5, with the switch 72 having three positions (off, 1 lamp, and 2 lamps," as
  • a switch 88 shown in FIG. 2, located near the top of the upper case portion 14 in a position directly beneath the lower edge of the lens 22.
  • the lantern is constructed so that the lens 22 closes the switch 88 and the lanterns electrical circuit when the lens 22 is in engagement with the upper portion of the battery case, but the electrical circuit is opened when the lens 22 and the hood 26 are disengaged from the battery case.
  • This safety feature prevents a person from getting a shock from the lanterns power source while changing lamps 24.
  • FIGS. 7 and 8 Another model of lantern containing embodiments of this invention is shown in FIGS. 7 and 8. That lantern is in many respects constructed similarly to the lantern 100 shown in FIGS. 1-6, and corresponding parts of lanterns 100 and 10 will be identified with character numbers having the same last two digits, e.g., battery case 12 having upper and lower portions 14 and 16, respectively, of lantern 10 correspond and are substantially identical with battery case 112 having upper and lower portions 114 and 116, respectively, of lantern 100.
  • the absence of such correspondence in character numbers between parts of lanterns 10 and 100 may generally be taken to mean that there are not corresponding parts or functions in the two lanterns. Only the significant differences between the two lanterns will be described in the following discussion of lantern 100.
  • Lantern 100 has a lens 122, a lamp 124, and a hood 126 which are generally circular in configuration.
  • the lamp 124 is situated in the enclosed space defined by the mating transparent lens 122 and opaque hood 126.
  • the lantern 100 is Constructed so that when the closed nut 160 is unscrewed from the threaded top of the rod 120 and the knob 156 is removed, the lens 122, the lamp 124, and the hood 126 may be lifted up and removed as a single illuminating unit 129.
  • the handle 128 attached to the top of the hood 126 may act both as a carrying handle for the fully assembled lantern and as a hanger to permit the illuminating unit 129 to be held by hand orto be hung or suspended from a hook at the top of a tent, trailer, or cabin.
  • the wires 176 carrying current to the lamp 124 are purposely made relatively long so that the distance between the illuminating unit 129 and the remainder of the lantern can be made great; for instance, the illuminating unit 129 may be hung at the top of a tent or cabin while'the remainder of the lantern rests on the ground or floor.
  • These wires 176 may be coiled and stored inside the opaque, generally cylindrical sleeve 125 (corresponding in position but not in function to the lens 122 of lantern which is positioned between the illuminating unit 129 and the battery case 112.
  • the electrical circuitry of lantern 100 may be made somewhat simpler than the circuitry of lantern 10. Since there is one lamp 124 ratherthan two as in lantern 10, the lantern 100 may use only a single switch 173 having, if desired, three positions, off, bright, and dim.” The rod 120 is .not used as a component of the electrical circuitry in lantern 100.
  • lantern 100 is designed so that by rotating knob 156 (which produces a rotation of rod 120) the hood 126, the lamp 224, the lens 122, the cylindrical sleeve 125, and the upper battery case portion 114 may be retained as a structurally engaged assembly while the upper and lower portions of the battery case 112 are disen'aged'from each other; when this occurs the conductive members 162 (not shown in FIGS. 7 and 8; see corresponding parts 62 in FIG. 5) are disengaged from the terminals of the batteries and the electrical circuit between the'batteries and the lamp 124 is opened. i
  • FIGS. 9 and 10 Still another model of lantern containing embodiments of this invention is shown in FIGS. 9 and 10. That lantern 200 is in many respects constructed simi larly to the lanterns 10 and 100 shown in FIGS. I-6 and 7-8, respectively, and where correspondence in parts and function exists, the parts of lantern 200 will be identified with character numbers having the same last two digits as the corresponding parts in lanterns l0 and 100.
  • the discussion of lantern 200 to follow below will focus primarily on the features which are found in lantern 200 but not in the other models and on the differences between lantern 200 and lanterns 10 and/or 100.
  • Lantern 200 has an illuminating unit 229 similar in most respects to the corresponding unit 129 of lantern 100.
  • That unit 229 comprises a lamp 224 situated in the enclosed space defined by the mating transparent lens 222 and opaque hood 226, with the unit 229 being provided with a carrying handle 228.
  • the illuminating unit FIG. 9 as being enclosed inside a transparent plastic film 277 which is fitted tightly around one of the arms 275.
  • the area inside the circular lens 222 and lamp 224 is provided with a mirror 231 to permit a camper to see while shaving, pinning up hair, etc.; alternatively, this area may be left unoccupied or may be equipped with electrical appliances such as radios, fans, insect sprayers, etc., which also draw power from the lanterns batteries.
  • the lantern 200 is substantially identical in construction with lantern 100.
  • Lantern 200 may use only a single switch 273 having, if desired, three positions, off, bright," and dim.
  • the rod 220 (not shown in FIGS. 9 and 10) which extendsfrom the interior to the exterior of. the battery case 212 is not used asa component of the electrical circuitry in lantern 200.
  • Lantern 200 is designed so that by rotating knob 256 (which produces a rotation ofrod 220) the hood 226, the lamp 224, the lens 222, the arms 275, and the upper battery case portion 214 may be retained as structurally engaged assembly while the upper and lower portions of the battery case 212 are disengaged from each other; when this occurs the conductive members 262 (not shown in FIGS. 9 and 10; see corresponding parts 62 in FIG. 5) are disengaged from the terminals of the batteries and the electrical circuit between the batteries and the lamp is opened.
  • a battery powered electric lantern comprising the combination of:
  • a battery case the case comprising an upper portion and a lower portion and defining a space inside the case for housing at least one battery;
  • the battery case engagement means for permitting the upper and lower portions of the battery case to be engaged and disengaged, the battery case engagement means comprising i. a rod secured to the upper portion of the case and extending into the interior of the case, and, ii. means secured to the lower portion of the case and engaging the rod inside the case;
