A power-ful blower is a useful auxiliary in theprevention of smoke. When an engineis shut off and before the air jets getto work, the firebox flues and front endare full of smoke that cannot be, forthe instant, controlled by the air such cases the blower makes up thedeficiency. The blower pipe should not be lessthan 1J4 ins. in diameter, with a quick-opening, independent valve, so ar-ranged that it can be used by eitherengineer or fireman, and an automaticvalve which turns steam into the blower. no r
