label: Description

Each end casting is further provided with a series of holes near the bottom properly adapted to receive tubes joined thereto by the process known as expanding. These tubes are joined at the front and back to the vertical tubes rising from the water-tube headers by means of hollow castings in which hand holes are provided that permit both sets of tubes to be expanded in the openings in the castings.
