Abstract: An adjustable height mounting pedestal (10) for public or coin telephones (18) comprises a tubular upright post (12) having a plurality of arrangements of mounting holes (80) corresponding to varying telephone mounting heights ranging from a drive-up curb side height to a standard handicap access height. A backboard mounting enclosure (16) is longitudinally aligned with and overlapping the upright post (12) such that the backboard (16) adjustably slides along the upright post (12) during installation of the mounting pedestal. A single installer can accurately determine the center height of a coin slot (19) of the telephone (18) before mounting the telephone within the backboard mounting enclosure (16) by use of a coin slot center height indicator (141). The upright post (12) allows mounting of a backboard (16) and telephone at a selectively variable height, and also allows the mounting of a second backboard (16') and telephone at the selected height.

Abstract: An adjustable height mounting pedestal for public or coin telephones comprises a tubular post having a plurality of knockouts at varying heights ranging from a drive-up curbside height to a standard handicap access height. A backboard mounting enclosure includes an opening therein that conforms to the peripheral configuration of the telephone for which the mounting is adapted. The configuration of the backboard extends about the telephone housing forward of the rear edge of the front housing of the telephone so as to protect the telephone from prying tools. The backboard and post include dividers for dividing the space within the backboard and post into electrically isolated channels for telephone wiring and for power wiring. Adjustable channels fit within selected knocked-out openings in the post when a particular height for the backboard is selected. The mounting channels and backboard are temporarily supported during assembly, to facilitate assembly by a single worker.

Abstract: A free standing outdoor telephone booth is provided with a photo voltaic (PV) array, one or more rechargeable storage batteries and electrical control circuit which includes a temperature compensated control for limiting the supply of electrical energy from the PV array to the rechargeable battery to avoid over charging the battery, an ambient light (solar insolation) sensing circuit for controlling the electrical lamp load, to turn the lamp ON during dark ambient and OFF during light ambient conditions. In addition, the total discharge limit of the storage battery is controlled to a safe operating limit and a means is disclosed to power a fluorescent lamp at energy conserving intensities with energy derived from the rechargeable storage battery. The lamp control circuitry is preferably constituted by a high frequency power inverter with regulated output power to energize a low wattage fluorescent lamp and to dim the fluorescent lamp when the telephone is not in use.

Abstract: A coin-operated public telephone apparatus employs one or more telephone units and coin operating and collecting equipment enclosed within rigid components of a support structure for maximum security and protection against vandalism and to enable installation where conventional coin-operated telephones requiring separate enclosures cannot be utilized due to space limitations. The coin box is spaced from the telephone unit to minimize the likelihood of damage by attempted theft. The structure is adaptable for use by persons of different heights including standing adults as well as handicapped persons in wheelchairs or as a drive-up unit for use by persons in an automobile.

Abstract: A mounting stud latching system is provided for a coin telephone mounting post having spaced front and back walls and an intermediate mounting wall, with an opening in the front wall dimensioned to receive and closely surround the side walls of a coin telephone housing. Mounting studs on the back of the telephone housing project through openings in the mounting wall and are engaged and retained by keyhole-shaped openings in a latching plate slideably mounted on the back surface of the mounting wall. A plurality of threaded fasteners are inserted through openings in the back wall of the telephone housing to engage threaded openings in the mounting wall to firmly mount the telephone. Improved means are provided for permanently mounting the sliding latch plate on the back surface of the mounting wall.

Abstract: A post-mounted coin-operated public telephone apparatus employs one or more telephone units and coin operating and collecting equipment enclosed within rigid components of the pole structure for maximum security and protection against vandalism and to enable installation where conventional coin-operated telephones requiring separate enclosures cannot be utilized due to space limitations. The coin box is spaced from the telephone unit to minimize the likelihood of damage by attempted theft. The structure is adaptable for use by persons of different heights including standing adults as well as handicapped persons in wheelchairs or as a drive-up unit for use by persons in an automobile.

Abstract: A continuous, moving length of substantially rigid thermoplastic synthetic resin material is marked with a hot die at spaced intervals along its length. The hot die is mounted for movement parallel to the direction of movement of the sheet from the sheet forming apparatus, and is actuated in coordination with a sheet cutter which cuts the continuous length into individual sheets so that a die mark is provided at the desired position on each sheet cut from the continuous length.
