The impulse which thebell received being expended, it will return to its normalposition by its own weight; the governor bolt 33 willstrike the end of rod 36, which will force piston 39downward, coming in direct contact with valve 43, andclosing the exhaust port and opening the inlet port,after cushioning on the pressure remaining underpiston 39, after the exhaust is closed. It will be notedthat valve 43 is operated only at the termination of thepiston stroke. This bell-ringer can be adjusted to use pressure inproportion to the stroke required. The adjustments aremade by means of valve-stem 42, which is secured in itsvarious positions by a pin. No change in the lengthof the connecting rod is required in changing the adjust-ment.
