Abstract

801,665. Controlling burners. ROBERTSHAW-FULTON CONTROLS CO. Oct. 19, 1955, No. 29867/55. Class 75(1) [Also in Groups XXIX and XXXVII] A control and indicating system for a fluid fuel burner comprises a manually operable fuel flow control valve 32, a thermally actuated fuel control valve 42, first and second indicating lamps 20, 22 connected in parallel, a first switch 24 connected between the parallel circuit and a source of electricity and adapted to be actuated in response to conditions established by the manually operable valve, so as to move between open and closed positions when the valve moves between open and closed positions for controlling energization of the first lamp, and a second switch 26 in series with the second lamp and operatively connected to the thermal valve so as to move between open and closed position when the thermal valve opens and closes. When open the manual valve outlet pressure moves a diaphragm 74 to close a leaf spring contact 82 of the first switch. Opening movement of the thermal valve closes leaf spring contacts of the second switch through a lever 98 and pin 94.
