Abstract
A method and apparatus is provided wherein the total elapsed time for a series of outgoing calls on a plurality of call lines of a telephone is accumulated for each of those lines by a plurality of clocks and switches operating in a monitoring circuit for the output lines. An operator of the telephone may note the accumulated time on each line so as not to exceed an allotted time as is used in different regions of wide area telephone services (WATS). When the timing apparatus is used with a key telephone, the timers are controlled by individual reed switches, each of which is associated with a respective key switch and activated by a magnet attached to said key switch.

In a telephone having a receiver, a receiver retainer, and a plurality of push buttons connected to a plurality of telephone call lines with a disconnect switch connected to the telephone call lines so as to be responsive to displacement of said receiver from said retainer to transmit a call when closed and to terminate the call when opened, a telephone call monitoring device for measuring the elapsed time of usage of selected ones of said telephone call lines for calls initiating from said telephone comprising a monitoring circuit including a plurality of timers electrically connected in parallel to one another in said monitoring circuit, a stop switch and means electrically connecting said stop switch in series with each of said timers, said stop switch switchable between conductive and non-conductive electrical states, start switch means associated with each said timer including a plurality of start switches mounted in a elongated strip, said strip positioned adjacent a set of said buttons, each said start switch being a reed switch mounted adjacent a respective one of said push buttons and switchable between conductive and non-conductive electrical states, activating members including magnetic means associated with each button of said set and its associated start switch, said activating members operative to switch an associated one of said start switches when its associated button is moved transversely of said strip, each of said timers in said monitoring circuit having an associated said start switch and being energized when its associated start switch and said stop switch are in conductive states and being deenergized when one of its associated start switch and said stop switch is in a non-conductive state, and accumulating means associated wih each of said timers for cumulatively storing and displaying the aggregate time lapse resulting from a series of calls as measured by the time duration that its respective timer is energized.
A telephone call monitoring device for accumulating the elapsed time of usage of a telephone, which telephone has at least one multiple position push button operative to select a desired telephone call line and a disconnect switch terminating a call on said telephone call line comprising:
- a reed switch in offset adjacent relation to said button;
- a magnet secured to an upper portion of said button, said magnet moveable in a path transverse of said reed switch and operative to place said reed switch in a conductive electrical state when said button is in a first position and to place said reed switch in a non-conductive electrical state when said button is in a second position;
- a stop switch switchable between conductive and nonconductive electrical states;
- monitoring circuit means for transmitting an electric signal from a signal generator to said stop switch and said reed switch;
- and
- a timing device connected to said circuit means for measuring the duration of said call, said timing device being activated when both said stop switch and said reed switch are in said conductive states and being deactivated when one of said stop switch and said reed switch is placed in a non-conductive state.
