In the Novemberissue of this paper attention was called tothe fact that a deflection of the stayboltscould be detected within ten seconds ofthe throwing of a piece of lighted wasteinto a cold firebox, and also that so far asstresses arising from variation of expan-sion is concerned, it makes no differenceas to the temperature of the water withwhich a cold boiler is filled. But, however this may be, it is safe tosay that the two rules set forth by are far from representing universalpractice in the United States becausethere is no universal uniformity. Of course, we try to avoid scaling, but. %^5 METHODS OF FIREDOORCONSTRUCTION. we dont do it and, when we dont, wesuffer accordingly. Before starting the test of steel fire-boxes on the Orleans, a considerable ex-tension was made in the practice of wash-ing out and filling with hot water. Inorder to obtain the best results, twelvefireboxes were ordered from the UnitedStates and put in service in were delivered complete with stay-bolts in place and these were made ofcharcoal iron as in American , in order to avoid as far as pos-sible the scaling of the firebox sheets, itwas decided to apply a special feedwaterdevice in the steam space by which thefeed was heated by the steam in theboiler, to a approximating that of the saturated steam. It is a very simple arrangement andis called the feed pans, and consists ofa simple plate, placed inside the shell 76 RAILWAY AND LOCOMOTIVE ENGINEERING March, 1920
