2 Claims.

This invention relates to exhaust deiiectors constructed to be attached to the exhaust pipes of steam or gasoline motors, and has for its object the improvement of such dei'lectors in the following particular condition of their operations. Ordinarily, when an exhaust deector of this character is placed upon the end. of the exhaust pipe of an automobile, the condensation creeps up around the top of the deflector, resulting in corrosion. The chemical nature of the exhaust is almost always liable to cause the plating or finish of the deector to become dlscolored, removed as a whole or in spots and the deector to be rendered unsightly, or tarnished, or partially destroyed and its external appearance made undesirable. This invention has for its object the prevention of such corrosion in operation, by means of a baiie plate which is secured to the spreading end of the deiector, usually by spot welding at the sides. 'I'he baille plate takes on the drip of the exhaust and the corrosion occurs at the edge of the bame plate instead of at the edge of the deector itself.

In the accompanying drawing the arrangement of the bailie plate in the deiiector is illustrated,

showing one form and arrangement of the parts associated.

Fig. 1 of the drawing is a side view showing all parts assembled. 1

Fig. 2 is a sectional view lengthwise of the de ector 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 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 deector showing a modied baille plate construction.

Throughout the drawing and description the same number is used to refer to the same part.

As -usually made the 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 diierent form.

dei'lector has a hollowv The baille or drip plate is shown as having its rear end in contact with the under surface 0f the spreading end 2, and thel baille plate is usually made with the downwardly extending sides t and 9 which are arranged against the 5 sides of the spreading end as shown. As illustrated in Fig. 4, a space iii remains between the edge of the baiile plate and the inside of the spreading discharge end of the deilector. The baille plate may be secured to the spreading end, 10 2 by spot welds ii, which do not injure the appearance of the delector.

'It is thought to be apparent that the baille plate may be formed integrally with the spreading end of the deector. In the sectional view Fig. 6 15 the spreading end i2 of the deflector has a portion at. the edge i3 turned down and under, the turned down edge constituting the bae plate as illustrated.

ln operation the gases and uid vapors of the 20 exhaust pass over the edge of the baffle plate instead of in contact with the edge of the spread end of the deilector, and the injurious corroding substances are found to act upon the barile plate almost entirely, thereby protecting the deiiector 25 edges and surfaces.

Having now described this invention and its purpose, I claim:

l. An exhaust deiiector, comprising a body portion constructed to be attached to an exhaust 30 pipe, the said body having a spreading discharge end, and the said end having attached transversely to its under surface a baille plate extending downwardly adjacent to the edge of the said discharge end of the deilector, the edge of the bae plate being spaced from the edge of the said end of the deiiector whereby the end edge of the deector is protected from corroding exhaust gases.

2. An exhaust deiiector, comprising a body portion constructed to be attached to an exhaust pipe, the said body having a spreading discharge end, and a baille plate located within said discharge 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 corroding gases.
