Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . of the arch, thedouble arch, walls and bridge walls, hav-ing a certain amount of batter and all inuse with the burner placed at the rear endof firebox with flash hole through bottomof firepan. Experience in this direc-tion has indicated that the fireboxesso fitted had too many fire brick, andthere was not an equal distribution ofheat to all parts of the box. The ar-rangement shown is practically the re-sult of a good many experiments. Thisnot only accomplishes the object offree and regular distribution of heat toall parts of the firebox, but has re-duced the first cost of fitting up andthe cost of maintenance by about 50per cent. It also aids materially inthe quick turning of engines at terminals. When repairs are needed on the in-terior of a firebox workmen are able toget at it in much less time than if theengine had been equipped with archor bridge wall, as the operator hasfree access to all parts of the fireboxwithout necessitating the removal ofany of the brick work. The arrange-. BRICK ARRANGEMENT WITH BURNER. ment has reduced the cost of boilerrepairs to the minimum at all divisionpoints and has proved that a largemass of brick in a locomotive fireboxtends to add to the expense of repairs,not only to the brickwork but to theboiler as well. Writing on the subject of firebrickin a locomotive firebox, Mr. T. W. Keintzelman, superintendent of motivepower of the Southern Pacific atSacramento, Cal., says: We all knowthat fire bricks are poor conductors ofheat and even at white heat they donot convey heat rapidly to fireboxsheets for steam making. We havetaken the most refractory fire brick
