, tain new anduseful Improvements in Oil or Gas Engines, of which the following is a specification.

The present invention relates to a means andapparatus for deodorizing or destroying the smell of exhaust-gases, such as are produced by gasolene, kerosene-oil, or sometimes in gas engines. and ordinarily escape from the yexhaust of such engines. v

It relates also to means combined with the deodorizer `for vaporizing the oil used and for heating the ignition-tube for firing the charge. v

The object of my invention is to provide an attachment whereby by a slight expenditure of fuel in addition to that which operates an engine the partially-burned odoriferous gases which may escape from the exfrom the odor can be obviated.

My invention is applicable to various types of oil, gas, or gasolene engines, `whether stationary or applied to Vehicle-work.

Figure 1 is a longitudinal section of an engine embodying my invention. Fig. 2 lis a longitudinal section of an engine in which the .piston on its forward stroke acts as a pump or compressing a charge of air. Fig. 3 is a vertical section of a modification of the deodorizer. Fig. 4 is a vertical section of a still furtherA modification of the deodorizer,

and Fig. 5 is a sectional detail of a modificar In Fig. 1 is represented the cylinder of an ordinary engine, the piston P of which moves back and forth, turning wheel W by an ordinary'crank. The engine is provided with any ordinary admission for air and fuel and for escape of exhaust-gases. It,in fact, represents any ordinary type of explosive-engine. Mounted near the engine is a fire-pot orfurnace F, containing either combustible as fuel, such as coke, anthracite coal, .or containing refractory material which can be heated by. fuel. The exhaust-gases assing through the exhaust ort or passage J of the engine ass through t e fuel mass in the firepot F, eing distributed therethrough by a suit-able grate G, and when these exhaustgases are so depleted of air that there is no oxygen for further combustion I provide a small air-pump A, which supplies a quantity l of fresh air, taldng the air in by its proper inlet-valve I and forcing the said air through a suitable valve A and passage A, so that it mixes with the exhaust-gases passing the port E and passes through the fire in the firepot F. This re in the fire-pot F once lighted continues to burn, and it is originally started in the ordinary Way of starting a fire by Opening the draft at I) and igniting the fuel in the fire-pot F. The heat of the lirepot F may be made in my invention to keep an ignition-tube T hot for firing the gases in the engine, and it, further, may be made to vaporize oil fed to the engine through an oilsupply O by means of suitable pumps along with air which is sent into the engine. No means are shown for forcing oil and air into the cylinder, as that is understood to be the same as in ordinary engines. The oil-pipe O, however, traverses the' heated interior of the fire-pot or furnace F and receives a certain portion of the heat, so that any oil which passes it is thoroughly vaporized before entering the cylinder C. Where the ackiug in the fire-pot F is in the form of sma particles, it acts also as a mufHer for the exhaust sound at E, and where it is made of small particles of refractory material, such as pumice-stone or fire-brick, the airump A is arranged to supply air mixed with) some fuel, such as oil, to the. furnace; The oil to be mixed with the air is drawn into the pump through a pipe O2, (see Fig. 5,) which is connected witha supply of oil Whennecessary in a manner not shown in the drawings. i

In Fig. 2 the air which reaches the fire-pot F is shown as pumped by the forward motlon of the piston P, the front end of the cylinder C being formed by a chamber or space with valves V V opening therein. When the piston P moves outwardly-fi. '6., toward the valves V V--they shut and-the air within the space within which the valves V V are situated is slightly compressed. After the piston has moved full 'forward it uncovers openings in the sides of the cylinder, as at B B, &c., whereby the air rushes into the cylinderspace back of the piston P and scavenges or washes out the burned charge formed during explosion. This, escaping bya suitable passage, as at E goes through the grate G of the fire-pot F, as before. In this case the waste gases are naturally mixed with a certain volume of fresh air which conveys enough oxygen to the fire to keep up the combustion; or

if the engine itself is supplied with an excess of oil through the pipe O, more than suiiicient r pot F, as by dividing the fire-pot into two.

sections by the septum or division D2, Fig. 3, and roviding suitable valves and mechanism or exchanging them at intervals, as at` Y and Y2, exhaust-gases may be fed to one f side or half of the section of the fire-pot, as

that just below R, while fresh air is injected under or through that below L. Suitable passages with openings are provided to feed the two gases-z'. e., the air and the Waste gases from the engine. For instance, the inlet-passage Y may be connected-to the exhaust-port E of the engine, (shown in Fig. 1

and the inlet Y2 may be connected to the air *.gases.

passage A of the engine, (shown in Fig. 1.) By shifting the valves Y and Y2 from side to side at intervals the two parts under R and L receive alternately'the air and the waste This shifting should be frequent enough to prevent the-loss of high temperature 1n the materials within the nre-space. To facilitate this, the fire-potF` is doublev' jacketed, as shown by the outer jacket and septum X Z, providing a' passagey for the movement of the incoming air,as shown by the arrows, whereby it is heated before it reaches the fire-space by any waste heat which is escaping from-'the Walls of the fire-pot. It is of course understood that in this instance the material placed within thev fire-potis combustible or the air-supply passing valve Y2 is charged with sufficient combustible to maintain the temperature of said material."

The septum which divides the two halves of the fire-space is of course continued so as to divide the passages between the iire-pot and the se tum Z, and casing X is constructed' so as to 'vide into-the two sections mentioned as working alternately.

In Fig. 4 a modification is shown in which the exhaustort E of the engine and the apassage A o the engine (shown in Fig. 1`) lead to different portions ofthe grate at the lower end of thel fire-pot or furnace F. The exhaust-gases and air passing through the port E and passage Al are mixed in the fire-pot. I-n this case also it Will of course be understood that the air passing through the assage A may be mixed with oil or other el, if desirable.

The heated mass in thefireot F of my invention serves primarily as a eodorizer; but at the same time it acts as a muflier for the exhaust-gases, diminishing the sound of their escape, and, further, it supplies heat to an oil-vaporizer passing therefrom or receiving heat therefrom and keeps ignition-tube T hot for the firing of the charges, T being entered into the mass of hot material at any suitable point. The oil-vaporizing tube O may of course be made much larger, and, particularly, the feed of the air admitted may be varied. The oil may pass along with the air to the vaporizer, as is commonly done in oilengines. Also the cylinder of the engine while shown unjacketed may be provided with a Water-jacket for keeping it cool, as is ordinarily done. My invention relates more particularly to the employment of a hot mass through which exhaust-gases are passed.

Having thus described my invention,l what I claim, and desire to secure by Letters Patent, is#- f l. The combination with an oil-engine and furnace, the heated material in which is traversed by the exhaust-gases in escaping, of a means for supplying air and combustible to said furnace for maintaining its high temperature, an ignitiontube for the engine which is heated by the furnace, and an oil-vaporizer also heated by the heat of the furnace,for the purpose set forth.
