Abstract

An emergency selective message sender that actuates a telephone dial automatically when an emergency arises and dials the telephone operator. The device is automatically actuated by heat or smoke and will send a selected message to the telephone operator about this. In case of a robbery, a switch can be closed by a person to manually actuate the device and another selected message will be sent to the telephone operator. The switch can be remote from the device and still cause the device to operate when the switch is actuated. The different messages are prerecorded on an endless tape and the proper selected message will be repeated so long as the device operates.

Claims

1. A telephone emergency device for use with a handset, cradletype telephone having a cradle, telephone switch buttons, and a spring-biased dial with openings therein:

a. a tape recorder having an endless tape with two parallel emergency messages thereon, said tape recorder being connectable to a loud speaker;

b. means for supporting the telephone receiver so that its mouthpiece will register with said loudspeaker and pick up the emergency message when the tape recorder is operated;

c. electrically controlled releasable means receivable in the telephone cradle for normally holding the telephone switch buttons in open position;

d. a first solenoid for actuating said electric means for freeing said telephone switch buttons for connecting the telephone with the telephone operator;

e. means for holding the spring-biased telephone dial in a predetermined cocked position so that when the diAl is freed it will automatically connect the telephone with the telephone operator;

f. a second solenoid for freeing said means that holds the telephone dial in a cocked position and permitting the dial to return to normal in order to connect with the telephone operator;

g. an electrical configuration including a switch which when manually closed will connect said first solenoid to a current source for energizing the solenoid and freeing the telephone switch buttons, said switch also connecting said second solenoid to a current source for energizing it and causing the telephone dial-engaging means to free the cocked dial and permit it to return to normal position, said switch also closing an electric circuit to said tape recorder for causing it to send out one of the prerecorded emergency messages;

h. a heat and smoke detector including a second switch which will be automatically closed by said detector and will connect said first and second solenoids to the current source and will close another circuit to said tape recorder for causing it to send out the other prerecorded emergency message for calling the fire department;

i. an automatic predetermined time delay switch circuit interposed between the closing of said first solenoid and said second solenoid so that said first solenoid will free the telephone switch buttons a predetermined time period before said second solenoid will free the cocked telephone dial; and

j. a second automatic predetermined time delay switch forming a part of the electrical configuration for cutting off the source of current to the configuration after said tape recorder has operated for a preset time interval.

2. The combination as set forth in claim 1:

and in which said telephone emergency device has a self-closing electric switch which is opened by the telephone receiver when placed in a predetermined position on the device, said switch being in electrical connection with said second solenoid for energizing it and causing said dial-holding means to free the dial until the receiver is placed in the predetermined position and contacts with said self-closing switch to open it.

3. The combination as set forth in claim 2:

and in which a warning light is in the electric circuit formed between said self-closing switch and said second solenoid, said light being illuminated until the telephone receiver is placed in the predetermined position and contacts the self-closing switch to open it.

4. A telephone emergency device for use with a handset, cradle-type telephone having a cradle, telephone switch buttons, and a spring-biased dial with openings therein;

a. a tape recorder having an endless tape with two parallel emergency messages thereon, said tape recorder being connectable to a loud speaker;

b. means for supporting the telephone receiver so that its mouthpiece will register with said loudspeaker and pick up the emergency message when the tape recorder is operated;

c. electrically controlled releasable means receivable in the telephone cradle for normally holding the telephone switch buttons in open position;

d. a first solenoid for actuating said electric means for freeing said telephone switch buttons for connecting the telephone with the telephone operator;

e. means for holding the spring-biased telephone dial in a predetermined cocked position so that when the dial is freed it will automatically connect the telephone with the telephone operator;

f. a second solenoid for freeing said means that holds the telephone dial in a cocked position and permitting the dial to return to normal in order to connect with the telephone operator;

g. an electrical configuration including a switch which when manually closed will connect said first solenoid to a current source for energizing the solenoid and freeing the telephone switch buttons, said switch also connecting said second solenoid to a current source for energizing it and causing the telephone dial-engaging means to free the cocked diAl and permit it to return to normal position, said switch also closing an electric circuit to said tape recorder for causing it to send out one of the prerecorded emergency messages; and

h. a heat and smoke detector including a second switch which will be automatically closed by said detector and will connect said first and second solenoids to the current source and will close another circuit to said tape recorder for causing it to send out the other prerecorded emergency message for calling the fire department;

i. an automatic predetermined time-delay switch circuit interposed between the closing of said first solenoid and said second solenoid so that said first solenoid will free the telephone switch buttons a predetermined time period before said second solenoid will free the cocked telephone dial;

j. said telephone emergency device having a self-closing electric switch that is opened by the telephone receiver when the latter is placed in a predetermined position on the device, said switch being in electrical connection with said second solenoid for energizing it and causing said dial-holding means to free the dial until the receiver is placed in the predetermined position and contacts with said self-closing switch to open it; and

k. said electrical configuration including a relay that is energized when connected to the current source by the removal of the telephone receiver from its predetermined position and the automatic closing of the self-closing switch, the energized relay closing a circuit that transfers the first time delay switch so that said second solenoid will free the cocked telephone dial a predetermined time period before said first solenoid will free the telephone switch buttons so that the dial tone can be heard through the receiver.
