  • Patent number: 5913475
    Abstract: An improved anti-stuffing coin return for a telephone paystation, which is highly resistant to explosives due to front and rear openings, has a pair of diverging side walls and at least one internal movable plate, all made from a high strength material. The outer casing may include a push button that cooperates with the movable plate to help move any materials stuffed therein and allow coins to flow to a coin retrieval area adjacent an open front area. Additionally, a coin slide in the coin path may pivot to substantially block the force and gases of any explosive materials detonated therein.

  • Patent number: 5431338
    Abstract: An improved protective coin return for a telephone paystation having a pivoted outer sweep flap with a downwardly depending end flap and at least one pivotable inner flap, all made from a high strength material. The outer sweep flap and the at least one inner flap replace the conventional door on coin returns so as to provide an open front portion whereby a telephone user may look into the coin retrieval area. Additionally, the outer and inner flaps cooperate together to expel unwanted materials from the coin return through a rear opening having a pivotable vapor flap cooperating therewith so that substantially all forces and gasses of any explosive materials detonated therein are blocked and dissipated.

  • Patent number: 4053226
    Abstract: A printer for exposing photographic material is shown with a printing table horizontally mounted within a cabinet to receive photosensitive material and copy. A transparent plate is pivotably attached to hold the photosensitive material and copy in contact above the table which may be of the vacuum type. The front of the vacuum table may or may not exceed beyond the front of the cabinet. A fixed panel may be provided to support an exposing light above the table, additionally the control panel and shutter mechanism may be part of this fixed panel. A movable plate at least partially opaque to actinic rays may be moved inwardly as the transparent plate is raised. A safelight, viewing or inspection light may be mounted within the cabinet. A lifting and latching handle may be mounted at the front edge of the transparent plate.
