GAS DESTROYER Filed July 5, 1932 INVENTOR ATTOR N EY Patented Nov. 7, 1933 UNITED STATES PATENT oFFlcE 2 Claims.

The invention relates to a gas destroyer for use with internal combustion engines.

The primary object of the invention is the provision of a device of this character, wherein carbon monoxide and other gases or fumes will be burned for destroying the same, thereby eliminating the possibility of the loss of life from inhalation-of such gases or fumes when operating the internal combustion engine.

Another object of the invention is the provision of a device of this character, wherein the exhaust from an internal combustion engine, that is, the gases present in the exhaust, will be burned for the consumption thereof and thereby freeing such exhaust of obnoxious or dangerous gases or fumes.

A further object of the invention is the provision of a device of this character, which is simple in construction, thoroughly reliable, readily and easily applied to the exhaust conduit of an internal combustion engine, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features oi.' construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary side elevation oi' an internal combustion engine showing the device constructed in accordance with the invention applied.

Figure 2 is an enlarged vertical longitudinal sectional view through the device.

Figure 3 is a sectional view on the line 3-3 of Figure 2 looking in the direction of the arrows.

Similar reference characters indicate corre- 40 spending parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a portion of an internal combustion engine having the usual fuel intake manifold B 5 and the exhaust manifold C respectively. In association with the exhaust manifold C is the gas destroyer constituting the present invention and hereinafter fully described. f

The gas destroyer comprises a cylindrical cas- 50 ing including inner and outer walls 5 and 6 respectively, these being spaced frornfe'ach other and 'within such space is an insulation or a fireproof lling 7, such for example, asbestos, the casing having a tapered end-8 this with the other 55 encl being open. The said other endgfof, the cas,-

ing has tted thereto a cap or head 9, the same being telescopically threaded upon the casing while the tapered end carries a coupling extension 10 for connection with the outermost section 11 of an exhaust pipe.

The cap or head 9 has centrally formed therewith a coupling nipple 12 which is joined through a fluid-tight joint 13 with the inner section 14 of the exhaust pipe, the latter being connected with the exhaust manifold C. This casing is in substitute for the conventional muiiler as employed in the exhaust pipe o1' an internal combustion engine.

Carried by the cap or head concentrically with relation to the coupling nipple 12 integral there- 70 with is an exhaust or discharge nozzle 15 having a contracted perforated free end 16, the same being centered with relation to the casing 5 and projected a distance therein, while the larger portion of said nozzle 15 is anchored or secured 75 v with the head or cap 9.

The casing has fitted therein spaced screens 17 and 18 respectively, the latter screen surrounding the contracted end portion 16 oi' the nozzle 15 and rearwardly of the perforations therein and this screen 18 serves to divide the casing into a firing chamber 19 and a chamber 20, the latter being concentric to the wider portion of the nozzle 15. The head or cap 9 has formed therein the concentrically arranged series of slots 21 and perforations 22, the said slots establishing communication with the interior of the nozzle 15 from the atmosphere, while the perforations 22 establish communication with the chamber 20 with the atmosphere. In other 90 Words, the slots 21 constitute primary air ports or entrances while the perforations 22 constitute secondary air ports or entrances. Mounted upon the coupling 12 of the head orcap 9 is an air intake regulator or shutter 23 which controls the slots 21 to regulate the intake oi' air therethrough from the atmosphere.

The coupling nipple 12 projects slightly into the casing and this projected portion of said nipple carries a tubular member 24 having formed therewith a Venturi Vnozzle 25, the major portion of said nozzle being perforated at 25 `and projected into the member 24 which is spa'cedfv fromandpconcentric thereof, the Venturi tip2ii openinghinto the nozzle 15.1l

The casing of thedevicelntermediatejof,its l .y ends and "at the' uppermost portion thereof is .f countersunk at 27 with an.4 opening for accom-f .l 'molating'fa spark plug 28 which is arrange'diin the-ignition system of the internal combustion 110 engine. This spark plug 28 when sparking ignites the gases and fumes let into the casing through the Venturi tip 26 and dischargenozzle 15, the gases or fumes being rendered cornbustible by the mixing of air admitted through the slots 2l and apertures 22 so that the exhaust from the manifold C of the engine A will have obnoxious and dangerous gases eliminated therefrom prior to the discharge of the exhaust through the outer section 11 of the exhaust pipe. It is of course understood that the exhaust from the manifold C under pressure will be forced into the device for the burning thereof in the sparking of the plug 28 which ignites gaseous fluid for destroying the gases or fumes during the working of the internal combustion engine prior to the discharge of the exhaust to the atmosphere through the exhaust pipe connected with the manifold C of said engine.

What is claimed isz- 1. A gas destroyer of the kind described comprising a cylindrical casing having inner and outer walls spacedv from each other, an insulating material between the said Walls, means for coupling one end of the casing to an exhaust manifold of an internal combustion engine, a coupling nipple included in said coupling and projected slightly into the casing, a tubular inember fitted on said nipple and having a Venturi nozzle, the said nozzle being perforated for a major portion thereof, spaced screens fitted interiorly of the casing, an exhaust nozzle related to the coupling nipple and having a contracted perforated free end extended through one of the screens, the exhaust nozzle being concentrically disposed with respect to the Venturi nozzle, a Venturi tip on said Venturi nozzle and in confronting relation to the contracted end of the exhaust nozzle, the said coupled end of the casing having primary and secondary air ports, and an adjustable shutter regulating said prrnary ports.

2. A gas destroyer of the kind described cornprising a cylindrical casing having inner and outer walls spaced from each other, an insulating material between the said Walls, means for coupling one end of the casing to an exhaust manifold of an internal combustion engine, a coupling nipple included in said coupling and projected slightly into the casing, a tubular member fitted on said nipple and having a Venturi nozzle, the said nozzle being perforated for a major portion thereof, spaced screens tted interiorly of the casing, an exhaust nozzle related to the coupling nipple and having a contracted perforated free end extended through one of the screens, the exhaust nozzle being concentrically disposed with respect to the Venturi nozzle, a Venturi tip on said Venturi nozzle and in confronting relation to the contracted end of the exhaust nozzle, the said coupled end of the casing having primary and secondary air ports, an adjustable shutter regulating said primary ports, and an ignition device within said casing adjacent to the reduced perforated end of the exhaust nozzle.
