I, JOSEPH SHUTTLEWORTH, of the Stamp End Works, Lincoln, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN PORTABLE AND OTHER
STEAM ENGINE BOILERS," to be as follows:-
This Invention has for its object improvements in portable and other steam
engine boilers. For these purposes, in constructing the fire-boxes of steam
boilers, the covering and side plates are made with flanches which project
upward and outward, and to which the tube plate and front plate are fixed,

space for cleaning out the sediment. The upper edges of the flanches of the
covering plates and of the tube and front plates receive the ends of the bars
or stays which strengthen the covering plate and give support to such bars
or stays.
