(Cl. 138-25) This invention relates to exhaust deiiectors The baille or drip plate ï is shown as having constructed to be attached to the exhaust pipes its rear end in contact with the under surface of steam or gasoline motors, and has for its >ob ject the improvement of such dei'lectors in the 0f _the spreading end 2, and thel baille plate is 5 following particular condition of their operations. usually made with the- downwardly extending Ordinarily, when an exhaust deñector of this sides t and 9 which are arranged against the 5 character is placed upon the end. of the exhaust sides of the spreading> end as shown. As illus pipe of an automobile, the condensation creeps up trated in Fig. 4, a space iii remains between the edge of the baiile plate and the inside of the around the top of the deflector, resulting in cor 10 rosion. The chemical nature of the exhaust is spreading discharge end of the deilector.

Having now described this invention and its Fig. 1 of the drawing is a side view showing all parts assembled. 1 30 Fig. 2 is a sectional view lengthwise of the de-ñector with this invention applied thereto. Fig. 3 is a bottom plan view. Fig. 4 is a front end view partly in section on the broken line t-t of Fig. 3 of the spreading 35 discharge end of the deiiector showing the spaced position of the baiiie plate. Fig. 5 is a sectional view on the broken line I5_5 of Fig. l. Fig. 6 is a longitudinal sectional view of the lo spreading discharge end of the deñector showing a modiñed baille plate construction. Throughout the drawing and description the same number is used to refer to the same part. As ~usually made the dei'lector has a hollowv 5 cylindrical body portion i, with a downwardly bent or turned spreading or divergent discharge end 2, having the downwardly extending sides 3 and il. The body l has the lengthwise opening 5 which permits the body to be secured upon an D exhaust pipe by means of some device equivalent to the clamp 6 shown in Fig. »5. The number and vstructure of the boit clamps 6v are not parts of the invention and may be of diiïerent form. purpose, I claim: > 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.
