Abstract

A telephone number index and switch device has a series of magnetic switches which are located in fixed positions with corresponding surfaces disposed along a preestablished path of movement of a card finder associated with cards having names and telephone numbers. A magnetic actuator is carried by the card finder but is not in physical contact with the magnetic switches for successively actuating the magnetic switches. A second switch separate and independent from the magnetic switches is used to complete the automatic dialing once a number is selected from the index and a magnetic switch has been actuated.

Dependent claims

In a telephone index and combined switch device for memory stored dialing data for automatic telephone dialing, the combination comprising:

multiple card index means including a plurality of cards one on another for visual listing of names and telephone numbers, each card including individual lines for individual names and telephone numbers, and finding means arranged for movement along a preestablished path of movement relative to said cards;
card switch means activated by positioning said finding means having a first mode and a second mode, said card switch means being connected in a first circuit arranged for engaging a latching circuit for an individual card, said first circuit being completed via said card switch means in said first mode and interrupted via said card switch means in said second mode, whereby, with a first card selection and with said card switch means in said first mode, the latching circuit for the first card selected remains in effect independently of the operation of said card switch means until said finding means is moved to a second card selection and said card switch means is in said first mode,
said card switch means including a plurality of magnetic flux actuated switching devices each including circuit connecting means for completing a circuit via each associated switching device when in the vicinity of a magnetic flux of a preselected strength, said switching devices being mounted at fixed positions with similarly oriented corresponding surfaces disposed along said preestablished path of movement of said finding means;
a single magnetic flux producing actuator movable with said finding means along said path in the vicinity of but not in physical contact with each switching device to provide a substantially uniform distance between said actuator and each switching device for applying substantially the same magnetic force on each switching device when that switching device is directly opposite said actuator during the movement of said actuator along said path while successively actuating said switching devices;
and
selector switch means operable separate and independent of said card switch means connected in a second circuit corresponding to a particular line and a particular card which, upon actuation after the card switch means is in the first mode, is effective to retrieve and automatically dial a telephone number stored at a location in a memory associated with said particular line.

In a telephone index and combined switch device for memory stored dialing data for automatic telephone dialing, the combination comprising:

multiple card index means including a plurality of cards one on another for visual listing of names and telephone numbers, each card including individual lines for individual names and telephone numbers, a cover positioned over said cards, and finding means on said cover arranged for movement along a preestablished path of movement relative to said cards for positioning an individual card for visual display of the card's content, said finding means being carried by and movable along said cover;
card switch means activated by positioning said finding means having a first mode when the cover is closed and a second mode when the cover is open, said card switch means being connected in a first circuit arranged for engaging a latching circuit for an individual card when said cover is closed, said first circuit being completed via said card switch means in said first mode and interrupted via said card switch means in said second mode, whereby, with a first card selection and with said card switch means in said first mode, the latching circuit for the first card selected remains in effect independently of the operation of said card switch means until said finding means is moved to a second card selection and said card switch means is in said first mode,
said card switch means including a plurality of magnetic flux actuated switching devices each including circuit connecting means for completing a circuit via each associated switching device when in the vicinity of a magnetic flux of a preselected strength, said switching devices being mounted at fixed positions with similarly oriented corresponding surfaces disposed along said preestablished path of movement of said finding means;
a single magnetic flux producing actuator movable with said finding means along said path in the vicinity of but not in physical contact with each switching device to provide a substantially uniform distance between said actuator and each switching device for applying substantially the same magnetic force on each switching device when that switching device is directly opposite said actuator during the movement of said actuator along said path while successively actuating said switching devices;
and
selector switch means operable separate and independent of said card switch means connected in a second circuit corresponding to a particular line and a particular card which, upon actuation after the card switch means is in the first mode, is effective to retrieve and automatically dial a telephone number stored at a location in a memory associated with said particular line.

In a telephone index and combined switch device for memory stored dialing data for automatic telephone dialing, the combination comprising:

multiple card index means including a plurality of cards one on another for visual listing of names and telephone numbers, each card including individual lines for individual names and telephone numbers, a cover positioned over said cards, and finding means on said cover arranged for movement along a preestablished path of movement relative to said cards for positioning an individual card for visual display of the card's content, said finding means being carried by and movable along said cover;
card switch means activated by positioning said finding means having a first mode when the cover is closed and a second mode when the cover is open, said card switch means being connected in a first circuit arranged for engaging a latching circuit for an individual card when said cover is closed, said first circuit being completed via said card switch means in said first mode and interrupted via said card switch means in said second mode, whereby, with a first card selection and with said card switch means in said first mode, the latching circuit for the first card selected remains in effect independently of the operation of said card switch means until said finding means is moved to a second card selection and said card switch means is in said first mode,
said card switch means being in the form of a ganged series of closely spaced magnetic relays carried by said multiple card index means arranged for successive operation,
said relays being mounted adjacent each other at substantially the same elevation with their tops in a single plane, said relays including circuit connecting means for completing a circuit via each associated magnetic relay when in the vicinity of a magnetic flux, said relays being enclosed on all sides at fixed positions in a block of a molded potting material,
said block including an upper surface closely adjacent to said plane of tops of said relays which are mounted parallel to said planar top, said potting material being non-metallic and having a high permeability to readily pass magnetic flux therethrough,
said finding means being carried by and movable along said cover and having a single magnetic flux producing actuator to successively actuate each of said circuit connecting means of an associated magnetic relay while disposed above but not in physical contact with each magnetic relay being actuated;
and
selector switch means operable separate and independent of said card switch means connected in a second circuit corresponding to a particular line and a particular card which, upon actuation after the card switch means is in the first mode, is effective to retrieve and automatically dial a telephone number stored at a location in a memory associated with said particular line.
