Abstract: A low cost metal housing for a telephone paystation incorporating a new upper housing locking method with modified internal housing construction providing more cost effective design. The housing incorporates a system of locking rods, push bars and a rocker bar all operated in response to a key operated cylinder lock wherein the locking rods are adapted to engage or disengage strike plates secured to the internal portion of a rear housing shell included as a portion of the telephone paystation assembly.

Abstract: A paystation telephone level control system is disclosed including a telephone receiver driven by a local amplifier and wherein two sets of attenuating resistors, a coarse attenuation set and a fine attenuation set, interface with connectable terminals of a binary control crosspoint switch. The presence or absence of coin tones and dialing tones are detected and the crosspoint switch discretely controlled by their presence to effect discrete levels of attenuation of signals fed to the receiver. In addition, the lever of attenuation during voice communications is a function of a pre-adjusted attenuation and a user selection.

Abstract: A coin-operated telephone having a housing enclosing a coin acceptor and an associated coin release mechanism which are positioned above a display area. A coin release actuator mechanism is mounted on top of the coin acceptor and includes a rocker arm which is pivoted downwardly by a coin release bar assembly which is secured to and extends across the interior of the housing and is pivoted downwardly by the coin release lever on the front of the housing. The assembly is located above the display area and provides ample clearance in the housing to later add "smart" features while also providing a large display area.

Abstract: A coin-operated telephone having a housing enclosing a coin acceptor having a coin release mechanism secured thereto. A coin release mechanism actuator assembly is carried in the housing and disposed for actuation of the coin release mechanism by causing upward pivotal movement thereof. The coin release mechanism includes a downwardly depending member which is engaged by a roller of the actuator assembly which is comprised of two pivotal L-shaped members connected by a link or rod for transmitting pivotal movement from a first of the pivoted members to a second of the pivoted members. Stops are provided to limit the movement of the members to prevent binding thereof.
