Abstract

PURPOSE: To provide a compensating means of simple structure in a friction clutch type safety device for discontinued flame of gas by following accurately to permanent elongation of a flame detecting wire due to elongation or creep of more than necessitated caused by continuous heating for a long period of time.
CONSTITUTION: When a flame 5 for detection is ignited under a condition that a safety valve 4 is opened by pushing a knob 25 and a valve operating rod 22 is pushed up to a position to open the valve at the same time, a prime moving lever 11 is pivoted in clockwise due to an operation of a tension spring 16 caused by thermal expansion of a flame detecting wire 12. Consequently, a latch-lever 10 is pivoted downwardly and a latch hole 20 is inclined, thereby, the rod 22 is locked by the peripheral surface of the hole 20 and the valve 4 is kept in opened. In such a device, an eccentric roller 18, contacting with the latch-lever 10 elastically by a compensating spring 26 and pivoting upwardly so as to compensate the clearance between both levers 10, 11, is pivotably supported at the pivoting end of the long arm side for the lever 11, and further, is constituted so as to be restored to its original state upon closing of the valve.
