The detailsas shown are self explanatory, and it needhardly be pointed out that the openingsfor the removal of the ashes being at thelowest points of the ash pan the removalof the ashes is instantaneous and com-plete, while the closing of the movabledoors are, by reason of their actingagainst the contracting surfaces of theash pan, self cleaning, while the operatinglevers by reason of their multiplied ap-.

In the absence of anyserious collision there is absolutely noth-ing to get out of order, for even if it werepossible for any portion of the ash panto warp after long service, the overlap-ping of the movable closing appliancesprevents any tendency to admit of anopening at these points of movable con-tact. It will also be noted that the air as that large class of inventors whoseminds naturally run to every conceivablechannel of human endeavor, and it wouldnot be surprising if the ash pan shouldassume new forms in the undiscoveredfuture. A word might be added in reference tothe fact that while the ashpan has re-ceived considerable attention in recentyears, there has come to our observationhere and there evidences that there aremechanical engineers who see
