Safety apparatus in gas heating device

A safety apparatus for use with a gas burner having a thermoelectrically activated safety valve for interrupting a flow of gas to said burner, a governor for maintaining constant gas pressure to said burner, a gas channel interconnecting said safety valve and said governor, and a thermocouple for generating a thermoelectromotive force in the presence of a pilot flame a pilot burner to electrically maintain said safety valve in an open position, said safety apparatus comprising:

• a gas pressure operator for sensing excessive pressure within said gas channel interconnecting said safety valve and said governor and initiating a shut-off of said gas supply to said burner upon sensing said excessive pressure;
• connecting means electrically connected to a solenoid in said safety valve for controlling on/off operation of said safety valve, and electrically connected to said thermocouple;
• and
• operation sensing means in communication with said gas pressure operator electrically disconnecting the generated thermoelectromotive force supplied to said safety valve so that said safety valve moves to an off position thereby stopping the flow of gas within said channel and extinguishing the flame at said burner.

A gas burner control device comprising a connecting device for coupling a thermocouple to a safety valve solenoid through a operation sensing device, said connecting device comprising:

• a body having a first horizontal passage and a longitudinal passage formed therein;
• a plug inserted into said longitudinal passage and having a second horizontal passage formed therein cooperating with said first horizontal passage;
• a first terminal and a second terminal positioned at opposing ends of said second horizontal passage;
• an insulating block disposed between and spacing part said first terminal and said second terminal;
• wherein said body electrically couples an exposed wire of said thermocouple at a first end of said first horizontal passage, an insulated wire of said thermocouple passes into said first end of said first horizontal passage to electrically couple said first terminal, and a second end of said first horizontal passage has disposed therein a transmission means insulated from said body, one end of said transmission means being connected with to said safety value solenoid and another end of said transmission means being connected with to said second terminal.
