Fletcher's New Gas Pressure Governors, for equalising the supply, and preventing 



waste and irregularity. 



These governors are sent out adjusted to about -fy pressure, which is the best and most economical for general 

 se, provided the gas pipes and meter are not too small for their work. If this is the case, any pressure can be 

 btained with perfect regularity by unscrewing the top cap of the regulator, and adding extra weights on the 

 isc. These weights can be supplied adjusted to any required pressure up to that of the main service.

These governors, with the exception of the f in. size, which has a screwed joint, are made with gland screws. 

 .hich renders their fixing a very simple matter. They must be fixed on the outlet pipe near the meter, and must 

 v perfectly horizontal. If not quite level, they are liable to work unsteadily.
