Divided and this application, iied January 12, 1914. Serial No. 811,556.

THOMAS VAN TUYL, citizens of the United' States, and residents of the city of Kankakee, in the county of Kankakee and State of illinois, have invented certain new and useful improvements in Mixing and Purifying Devices; and we do hereby'declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This application constitutes a division of our cospending application for Convertible internal combustion engines, filed August 3l, 1912, Serial No. 718,029. v

A. number of different types of carbureters have been devised capable of use with inmechanisms burning fuel, lout these devices, except perhaps for an ordinary screen sometimes connected thereto, are not suited to .mix and purify the mixture and remove forminute globules of the fuel in liqu1d form.

This invention relates to a means preferably for use with internal combustion engines in which the fuel and air is supplied to 53@ the cylinder from the crank case, and usu.-

ally under pressure, although not limited in its use to this type of engine.

lt is an object of this invention to provide a means for thoroughly intermingling fuel a` supply of air insuring thorough miX ing of the air and furthermore for removing particles of liquidfrom the gases to collect and permit return of said liquids to the scarce from which they came.

lit is also yan Vohject of this 'invention to provide an internal combustion engine of such a construction as to admit the use in combination therewith of a device embody- I ing :the principles of our invention conveniently therewith.

lit is also 'an object of this invention to provide a heated mixing 4device comprising plurality of tortuous passages serving to thoroughly mix air and vaporized fuel and also acting to vaporize liquid particles of fuel passing therethrough, and at the same time free the air vand 'fuel from entrained particles of oil or moisture.

lt is also` an object of this Ainvention to construct mixing and purifying mechanism' combustion engines as well as other l 4tlon, associated therewith.

prevent passage of Yports 3, in the cylinder,

consisting of a plurality of corrugated plates laid up at angles with one another in which the corrugations are disposed at an angle in said plates and at an' angle to the line of passage of gases flowing through the passage in which the plates are placed, and in a position to receive the heat from the engine to assist in vapor-ization of the fuel passing therethrough.

lt is finally an object of this invention to construct a simple, cheap and durable device adapted to miX air and4 fuel and free the air vandfuel from entrained impurities.

The invention (in a' preferred form) is hereinafter more fully described and defined in the accompanying drawings and.

specification.

n the drawings; Figure l is a central Vertical section taken through a convertible two and four cycle engine illustrating 'a device embody-ing the principles of our inven Fig. 2 is a transverse horizontal section through the engine with parts in elevation. Fig. 3 .is a front facel view of the plates forming a part of our device. Fig. 4 is a view on line 4*-4 of Fig. 3, showing two plates. Fig. 5 is a section on line 5 5 of Fig. 3, showing two plates.

As shown in the drawings: Uur device is shown in connection with an engine comprising a cylinder 1, a water jacket 2, inlet ports 3, to admit air and fuel to the crank case, exhaust ports 4f, and a rotary valve element 5, adapted to open and close a passage communicatingl with said exhaust ports. A trunk piston 6, slidably mounted within the cylinder l, is provided with an abutment 7, for a purpose hereinafter described. As is customary, a connecting rod 8. connects the piston with a crank shaft 9, the connecting rod projecting into a crank case in whicho said,crank shaft is jounnaled. manifold 11, connected to a carbureter or source of air and fuel supply, communicates through' suitable passages 'ith the inlet and as the lower end of the piston moves upwardly past said port 3, such upward movement causing a re duction of'pressure inthe crank case, the aii" and fuel are drawn through the ports 3, and with a downward movement of the piston the ports are'closed and the charge is conipressed. As the piston continues to move downwardly, it uncovers inlet ports l2, on theopposite side of the cylinder from said An intake ports 11', to convey the burnt gases to a suitable point of exhaust. A cover plate 14, is bolted on the engine forming one wall of a passage leading from the crank case to the inlet ports 12, and mounted in said passage, and, if desired, secured on said removable plate 14, is the mixing mechanism for the 1-5 exigirle. This comprises a series of corru- ` gated plates 15 and 16, the corrugations of which run diagonally of the plates, and said plates are set up adjacent one another, so that the respective corrugations 17 and 18, 20 thereon, on adjacent plates lying in contact with one another, are at substantially a right angle with each other. In Figs. e and 5, we have shown two ,plates laid up adjacent one another, but in actual .use we pro-A vide a number sufficient to entirely fill the passage through which the gases pass.

The operation is as follows: It is obvious that when the rotary Valve element 5, is at rest in the position shown in Fig. 1, with '30 the passagethrough the exhaust pipe 13, open at all times, the engine operates on the two cycle principle acting with a downstroke of the piston to exhaust the gases through the ports 4, as the piston passes thereover,

and immediately thereafter to receive a fresh charge of fuel under pressure through the inlet ports 12, from the crank ease, and withan upward stroke ofthe piston serving to compress and fire the charge within the cyl- 4Q inder, However, by suitable mechanism, the details of which are not entered into in the present application but are described in our co-pending application Serial No. 718,029, already mentioned, the rotary valve 5, may be caused to maintain the ports 4, closed, except on every fourth stroke of the piston,- at which time, owing to the proper sequence of compression and firing having taken place as usual in a four cycle engine,

the burnt gases are exhausted. However, the fuel is introduced through the intake pipe 1'1, and ports 3, to the crank case 10, and is there compressed and driven upwardly through the inlet ports 12, in all y cases whether the engine is acting either on;

a two cycle or four cycle principle. Of course, the crank case 10, is partially filled with lubricating oil which is splashed considerably with movement of the connecting rod therethrough, and the fuel and the air are considerably intermixed with each other and with the lubricating` oil. As ythe mixture flows toward the open inlet ports 12,

the entrained lubricating oil is caught in the meshes of the corrugated plates, and due to the tortuous passages through which the fuel and air are caused to pass, the latter are thoroughly vmingled with oneA another, but the globules of lubricating oil collected therefrom drop back into the crank case. Owing to the fact that the corrugated plates yare placed adjacent the engine cylinder,

they are maintained at a relatively high temperature at all times when the motor is running, so that in the event of globules of liquid fuel finding their way thereto, said globules are vaporized and pass into the cylinder in proper condition for firing.

le are aware that various details of construction may be varied through a wide range without departing from the principles of our invention. v Te therefore do not purpose limiting the patent granted otherwise" than necessitated by the prior art.

lVe claim as our invention:

1. The combination with a convertible two cycle and four cycle engine having a passage communicating with the cylinder and crank case thereof, of mixing means disposed in said passage comprising corru- 90 gated plates arranged with the corrugations at an angle to one another.

2. The combination with a convertible A two cycle and four cycle engine having a passage communicating between the cylinder and the crank case, of mixing means comprising a plurality of corrugated plates disposed in said passage, said plates laid fiat against one another with the corrugations at an angle to one another forming passages therebetween extending diagonally in the passage in which said plates are disposed.

' 3. A mixing and purifying device comprising a lplurality of plates, and corrugations extending diagonally thereacross, said plates laid up adjacent one another with the adjacent corrugations disposed at right an gles to one another.

4. The combination with an internal combustion engine comprising a cylinder, of a device for mixing and purifying air of entrained impurities comprising a plurality of corrugated plates mounted in a passage adjacentrthe cylinder of the internal combustion enginel to be heated thereby, with the corrugations of adjacent plates laid at right ,angles affording obliquely disposed passages for the fluid passing therebetween.
