l. An exhaust deiiector, comprising a body por
tion constructed to be attached to an exhaust 30
pipe, the said body having a spreading discharge
end, and the said end having attached trans
versely to its under surface a baille plate extend
ing downwardly adjacent to the edge of the said
discharge end of the deilector, the edge of the
bañe plate being spaced from the edge of the said 36
end of the deiiector whereby the end edge of the
deñector is protected from corroding exhaust
gases.
2. An exhaust deiiector, comprising a body por
tion constructed to be attached to an exhaust 40
pipe, the said body having a spreading discharge
end, and a baille plate located within said dis
charge end and transversely secured in contact
with the under surface of said end, said baille 45
plate being extended downwardly whereby the
lower edge of the baille plate-is spaced from and
protects the end edge of the deiiector from cor
roding gases.
