The lever on stopcock is raised and allowed to rest 
on the pin, as shown on cut, then the burner is ignited. 
After a few minutes the springs will expand so that 
the lever will slip off" the pin and rest on the disc. 
Should the gas be accidentally blown out, the springs 
will contract and turn the disc and allow the lever to 
drop, thus closing off the flow of gas, preventing an 
explosion.
