A telephone ear piece lock is disclosed to prevent unauthorized use of a protected telephone instrument. The ear piece lock includes a rim mounting bracket that is permanently affixed near the receiver end of the telephone and has a flat arm radially outwardly extending therefrom. The arm is provided with a transverse slot for instrument locking purposes. A disc-like cover overfits the receiver end to function as a sound barrier when tightly held over the receiver end. A bent locking finger extends from the cover and is configured to insert through the bracket slot. The locking finger is provided with an opening to receive a portion of a portable lock therethrough, the lock serving to prevent removal of the cover from its shielding position over the telephone receiver end.
An attachment for a telephone handset includes a portion which engages a groove in the handset and which may be rotated along the groove. A lens is mounted in a frame rotatably attached to the portion which engages the handset to allow the lens to be oriented for left or right handed use. A connection between the lens frame and the portion engaging in the handset includes a socket which receives flexible projections for holding the frame in any of several desired orientations. In use, a lens is positioned to provide optical assistance for an operator while simultaneously talking on the telephone.
A vandal-proof handset for a pay telephone having apertures therein for allowing sound to pass therethrough. The handset includes a transducer for converting either sound to electrical signals or electrical signals to sound. The transducer is positioned within the handset proximate the apertures such that the sound is transmitted or received by the transducer through the apertures. A disk member for preventing access to the transducer through the aperture includes openings therein for allowing sound to pass therethrough. The disk member is positioned between the handset apertures and the transducer such that the openings in the disk member and the apertures in the handset are not in registry. The transducer, therefore, is not accessible through the disk member openings.
