Patented Oct. 3, 1939 UNITED STATES PATENT OFFICE GAS BURNER deceased Application April 10, 1936, Serial No. 73,707 Renewed April 25, 1938 7 Claims. (Cl. 60--30) My invention relates to a new and useful improvement in a gas burner adapted foi` use in completing tne ecmbition of gases which are exhausted from internal combustion engines and 5 has for its object the provisioniof a device of this class which will be simple in structure, economical of manufacture, durable, highly eilicient in u and easily and quickly installed.

Another object of the invention is the provil sion' of a mechanism mounted in the exhaust manifold and so arranged and constructed as to facilitate further combustion of the gases exhausted from an internal combustion engine.-

Another object of the invention is the provi- 13 sion in a device of this class of a perforated member mounted in the exhaust manifold for the reception of exhaust gases and the provision of blast delivery means whereby suflicient air may be delivered into the presence of the exhaust 20 gases to assist in combustion.

Other objects will appear hereinafter.

'I'he invention consists in the combination and arrangement of parts hereinafter described and claimed.

y The invention will be best understood by a reference to the accompanying drawlng`which forms a part of this specification, and in which, Fig. 1 is a side elevational view of the invention with a part broken away showing it mounted on :zo the engine.

Fig. 2 is a longitudinal. vertical, sectional view of the invention.

` Fig. 3 is a sectional view taken on line 3 3 of Fig. 1. 35 In the drawing I have illustrated the invention used with an internal combustion engine 9 having anl exhaust control valve III to control the flow of the exhaust gases to the exhaust port I I. l A number of these valves are, of course, provided 40 on the multi-cylinder engines but suflicient is illustrated to indicate the nature of the invention. Almanifold I2 is mounted on the side of the engine block l and has openings I3 communieating with the exhaust ports II. Extending if lengthwise of the manifold is a hood-forming portion I5 which communicates with the mani-v fold and also communicates with-a conduit I0 adapted to deliver air from the blower I1 which ais operated by means of the pulley I8 and the 50 belt l). The communication of the hood-forming portion li with the interior of the manifold is through the openings Il formed in the wall 30. Positioned in the exhaust manifold is a cylinder having perforations 2I formed therein and 55 closed at one end with the perforated end wall 22. 'I'he opposite end abuts against the end wall 23 of the manifold I2. This perforated cylinder 20 is provided with the openings I3' positioned opposite the inlet openings I3 of the intake manifold I2, so that the exhaust gas will flow into the 5 perforated cylinder 20. The air delivered from the blower will also enter the perforated cylinder 20 through the perforations 2| and mingle with the gases. Perforated partitions 24 and 25 are mounted in the cylinder 20. An outlet pipe 26 10 communicates through the opening 21 formed in the end Wall 28 of the manifold I2.

The construction is such that as the hot and burning exhaust gases are passed into the cylinder 20 the air delivered thereto will be delivered 15 in such volume as to further assist combustion and thus effect a complete combustion of the gases. In this way the kobnoxious odors which are frequently imbued from internal combustion engines may be eliminated and the noiseless op- 20 eration of the engine effected free from odors.

While I have illustrated and described the preferred form of construction, I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as may appear within the scope of the appended claims.

Having thus described my invention, what I claim as new `and desire to secure by Letters Patent is: 30
