EXHAUST RAIN PROTECTOR Filed May 17, 1949 INVENTOR.
Patented Mar. 10, 1953 UNITED STATES PATENT OFFICE EXHAUST RAIN PROTECTOR Wayne Brockelsby, Prospect, Pa.
Application May 17, 1949, Serial No. 93,710
1 Claim. 1
This invention relates to rain protective covers for exhaust pipes of diesel engines or the like, wherein the exhaust is disposed vertically with the opening above the top of the vehicle.
It is among the objects of the invention to provide a baffle cover for exhaust pipes which shall prevent rain from collecting in the exhaust pipe without interference with the normal exhaust function of the engine; in other words, without creating any back pressure.
The invention will become more apparent from a consideration of the accompanying drawing, constituting a part hereof, in which like reference characters designate like parts, and in which Fig. l is a top plan view of an exhaust pipe rain protector embodying the principlesof this invention;
Fig. 2 a side elevational view, partially in cross section, of the rain protector shown in Fig. 1; and
Fig. 3 a transverse section taken along the line 3--3, Fig. 2.
In the drawing numeral 1 designates a cylindrical housing having an adapter 2 for fitting on the end of an exhaust pipe to which it is attached in any suitable manner as by a press fit, clamping ring, set screw or otherwise. Numeral 3 designates the exhaust opening at the top which is in the shape of a segment as shown in Fig. l. The area of the adapter portion 2 and the segment opening 3 is the same so that there will be no back pressure on the exhaust.
The housing I is chamfered as shown at 4 which constitutes the roof or cover of the closed area of the housing I, the chamfer being at approximately a 45 angle. Disposed within the housing I is a pair of baflle plates 5 and 6, also disposed at a 45 angle, which if extended would respectively form right angles with the cover 4 and with each other. The area between the end of the bafiie 6 and the face of baffle 5, and the area between the end of baflle 5 and the slanting wall 4 is substantially greater than the areas of the adapter 2 and the exhaust opening 3 for the purpose of preventing back pressure.
Baffles 5 and 6 terminate in what may be termed rain spouts I and 8, respectively, which, as shown in Fig. 1, have lips 9 and III that extend beyond the walls of the housing I and which constitute umbrella portions for the spouts l and 8 to prevent ice forming and closing the spout openings of the housing I. The arrows indicate the path of travel of the exhaust fumes through the maze type rain protector and the short arrows indicate the flow of rain water such as might enter the exhaust through the top opening 3. In the main the flow would be from the spout 1. However, if any should pass the end of baille 5 it would collect on the baflle 6 and flow out at the spout 8.
It is evident from the foregoing description of this invention that the maze type baffle exhaust pipe rain protector assures that no rain will enter the exhaust pipe without causing back pressure on the exhaust of the engine. The type of exhaust rain cover herein described is particularly useful on diesel engine exhaust pipes which extend in a vertical direction.
Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.
I claim:
A rain trap for exhaust pipes of automotive vehicles comprising a housing having an adapter for mounting in the exhaust line of an engine and having its axis ofiset to one side of the axis of said adapter, an outlet at the top of the housing in alignment with the exhaust line adapter and oppositely disposed baiiie walls disposed in the path of the exhaust gases between the adapter connection and the outlet to divert the exhaust fumes into the offset portion of the housing, said housing having a drain hole at the point of connection of the baffle walls to the housing wall.
WAYNE BROCKELSBY.
