Reference now being had to the A. designates a plate which is preferably convexed upon its face, whichfisadapted to engage the inner concaved surface of a bo ler in connection with which "the device" is used. Said plate is provided with anoval shaped projecting portion B'adapted teen-" gage a similarly outlined hole inthe boiler,
said projecting portion desi gnedto extend through the wallof the boiler, and 3' isa A.
