Patent for a new and improved drier. This design "relates to improvements in driers for lumber . . . and the objects of [the] improvement are to provide, with stackless arches having a closed top and openings in the side, another arch or arches alongside of the first with openings in its sides, and pendent deflecting-plates to arrest all sparks that may issue from a furnace also provided with deflecting walls or plates, and thereby secure perfect safety in the use of that class of driers" (lines 9-23).
