Spark-Arrester

Patent for "improvements whereby the sparks from a locomotive will be passed directly from the flues through the stack and the outer air will be admitted, which will keep the cinders in motion and force them through fine perforations and against the hard surfaces until they are thoroughly pulverized and all the fire therein is extinguished, and which .will thereby prevent the danger to combustible products by fire thrown from an engine and which will not in any way decrease or interfere with the efficient work of the locomotive" (lines 17-29).
