In practice it isfound that there is a certain speed whichwill give the proper distribution undernormal conditions, and the stoker shouldbe operated at this speed, except whenoccasionally it may be advisable to fireheavier at the front or rear of the fire-box.

The upper part of the stoker casingforms a box-shaped chamber known asthe shovel box, which is covered byhinged lids. The forward end of thisbox is open to the firebox and the shovelsswing therein. The total height of thebox is S/z ins. over the cover. The stokerthus uses the lower 5/i ins. of the fireboxopening, and that part of the door open-ing above the stoker is closed by a butter-fly door, which is used for inspection andhand firing if necessary. The shovelsarc L-shaped, with a flat bottom anrl a shovel has passed over the elevator; thenil;e movement is rapidly accelerated untilthe shovel tip has entered the fireboxwhen it is rapidly decelerated.
