An opening may be provided in the bottom of the spark-box,through which cinders may be removed in case of any stop-page in the passages leading from the spark-box back to thefire-box. This opening, if provided, will of course be keptclosed, except when opened for the purpose of removingcinders. Mr. Wilsons patent is dated .\pril 26. 1887. and is num-bered 361,738.
