[Fig. 3282] a front end view of the boiler, and [Fig. 3283] a ground plan of the brickwork. When the front plate of the boiler setting extends above the middle of the boiler, as in [Fig. 3279], it is said to have a “full arch front.” Whereas when this plate or casting extends to the middle only of the boiler, it is said to have a half arch front.
