Title (EN) TELEPHONE WITH LONG DISTANCE DIALING LOCKOUT
(FR) TELEPHONE AVEC VERROUILLAGE DE COMPOSITION A LONGUE DISTANCE
Abstract: front page image
(EN)When zero on a telephone is dialed first by an unauthorized person hoping to establish a long distance line, a first blocking-spring (32) actuated by a boss (24) driven from the dial (17) arrests reverse rotation of a lug (28) before it can separate the signalling contacts (29, 30) so that zero is not signalled but another digit is is signaled instead. A second blocking spring (41) is actuated by the boss as it returns to starting position for holding the first spring (32) out of engagement with the lug (28) so that a local number can be dialed. For normal operation of the telephone, a manually operable member (39) is moved into a position in which it prevents the lug-stopping actuation of the first spring. The telephone also can be set to prevent all outgoing calls while permitting incoming calls to be received.
(FR)Lorsqu"une personne non-autorisee compose en premier sur le telephone le chiffre 0 en esperant etablir une communication a longue distance, un premier ressort de blocage (32) actionne par une protuberance (24) entrainee a partir du cadran (17) arrete la rotation inverse d"un ergot (28) avant qu"il ne separe les contacts de signalisation (29, 30) de sorte que le zero n"est pas signale mais un autre chiffre est signale a sa place. Un second ressort de blocage (41) est actionne par la protuberance lors de son retour en position de depart pour maintenir le premier ressort (32) degage de l"ergot (28) de maniere a ce qu"un numero local puisse etre compose. En fonctionnement normal un element a fonctionnement manuel (39) est deplace dans une position dans laquelle il empeche le premier ressort d"arreter l"ergot (28). Le telephone peut egalement etre regle pour empecher les appels vers l"exterieur de sortir tout en permettant des appels venant de l"exterieur d"aboutir.
