The Robinson locomotive superheater,so named because it is the invention of for their reception, have their ends ex-panded direct into tlie header, and hereinis to be found the fundamental differencebetween the Robinson and other kinds ofsmoke-tube superheaters. Flanged, orother special joints, for connecting thesesteam tubes to the header are thus doneaway with, as such joints are claimed inmany cases to cause leakage. Anotheressential feature of the Robinson appara-tus is the employment of steam jets, ordraught retarders, in place of mechanicaldampers, for the purpose of preventing.
