  • Patent number: 6278545
    Abstract: The apparatus (10) for providing magnification for a package (1,2) is designed to provide the user with an apparatus that will allow the user to have a magnification unit to enable him or her to read the instructions of directions on the side of a package (1,2). This is especially valuable for use on prescription bottles used by elderly individuals in situations where improper use of medicines could lead to disastrous consequences. The magnification apparatus (10) for packaging (1,2) comprises a cap (12) that contains a magnifying lens (11) that is molded or manufactured into the cap (12). The focal length of the lens is designed to be longer than the package (1,2) that is positioned upon in order to minimize any problems caused by light at the focal point. The lens (11) can be clear, opaque or colored as determined by the contents of the package (1,2).

  • Patent number: 4572157
    Abstract: A stove adapter for attachment to and use with a camping lantern includes a substantially cylindrical base member having an upper cooking surface and a plurality of extension arms pivotally attached to the base member. When opened radially outwardly, the extension arms provide an enlarged cooking surface for supporting, for example, a large skillet. When retracted inwardly, the bail of the lantern swings overhead to carry the lantern and the attached stove adapter. When opened, a first portion of each extension arm extends downwardly and engages the side of the cylindrical base member to support the arm in the plane of the cooking surface. When closed, the first portion extends upwardly to provide a stop for retaining cookware on the stove adapter. An over center spring collar is also provided to maintain the extension arms in both the open and closed positions and to retain the cookware on the cooking surface when the arms are retracted.
