is most clearly shown in liig. 3,1 extend the top 2 down ns shown :it 18 to ilorm a chamber -l-O es hereafter described. In the extended port 5 is a duct 't9-2G from the inletI 6 to the 'face of the top and :ils-o n duct il `rom the time to the chamber 4.0. The hydro-carbon or oil enters through the inlet. (l and passes through the duct lll- Q() to the fece end thence through the duct 21 to the chamber 40, the admission tothe inlet duct- 21, lioiveveijbeing controlled by a suit- (see Figa'. l) the mixture or gas being con-l able Valve 22 or its equivalent. As shown,

Za il the valve 22 is pivotally secured lto the top 5 by means ofl a pin 23 and screw 24. The

construction of the valve member 22 is most clearly shown in Fig.- 7 in which 26 is a chamber slot or groove in the face of the same arranged with an edge 261 eccentric to the pin 23 or its axis of rotation so that as the valve member moves back and forth over the face of the top 5 it will regulate or control the amount of oil or hydro-carbon admitted through the duct 21 to theA interior of the device, the duct being open to the chamber or slot 2d in the valve member. This is most clearly shown in Fig. 1 in which the openings 26 and ducts 2O and 21 are shown in dotted lines.v The valve member 22 may be controlled and maintained in position in any suitable manner. As'shown, itis resiliently maintained against the face of the top 5 by means of a member 27 provided with a stem 28 and a part 29 secured to the top part 5 by a screw 31 and extended as at'SO. The end is provided with an extension 32 arranged to coperate with a spring 33 and maintain the same in position, the resilient member or spring 33 acting between the arm and the member 27, thereby maintaining the valve 22 tightly against the face of the top. The valve member 22 may be operated by a rod 25.1 secured to the end 25 or by equivalent means. ln the construction shown the amount ofair admitted to the. inlet 8 is also controlled by the member 22, as most clearly shown in Fig. 7. To give vadjustability to member 22 in controlling the amount of air admitted through the yinlet S the member may be provided with one or more adjustable extensions 34 and secured to the member'22 by screws 36 and 3T extending through the upper face of the member 22 through slots 38` and 39. In this manner the size of the member 22 may be adjusted so that the amount of air and oil admitted to the interior of the device will be in the desired proportions.

Y Nithin the shell is arranged a valve member 41 arranged to coperate with a seat 42 on the extended part 18 of the top and con- 'trol the air and hydro-carbon or oil passing through the casing, the same with the part 1S forming a chamber 40. One of the parts, as shown, the member 41 is provided with lugs arranged to guide the valve during its movement, a spring 44 being provided for normally maintaining the valve in its closed position. The valve member 41 is preferably provided with a stem 43 having a chamber 45 therein normally closed by a cap 451. The valve member 41 carries a hydrocarbon or oilcontrolling valve member 46 arranged to control the amount of oil or hydro-carbon admitted through the duct 21 to the chamber 40, the same being normally maintained in its closed position when the valve member 41 is closed by means of a resilient member 49 and a pin 50, the movement of the same being limited by the enlarged end 48 positioned in the chamberl 45. lVith this construction a close tit is obtained between the valve member 46 and its seat 47 and the valve'member 41 and its s'eat 42.. Any slight Wear, however, of one part will not aliect the adjustment or operation of the other part so that both valves are always pertectly'adjusted and seated. 11E desired; however, they may be made integral, in .Which case the operation will be substantially the same.

The operation ofthe device may be brieiiy described as follows: Assuming that there is a suction caused bythe engine or the like at one of the outlets 9, the valve 22 being iny a position so that the duct .21 land the air inlet 8 are open. Then the suction will cause the valves 41 and 46 to open, admitting the hydro-carbon andy air to the interior of the shell 12 from whence it must be drawn through the angular openings 161 to reach` the engine cylinder or where required. As it passes through the angular openings it will be thoroughly co-mixed and vaporized, giving a highly etlicient charge. 1t may also be co-mingled to a certain extent in passing betweenthe valve 41 and its seat 42, but a thorough mixing occurs as it passes through theangular openings 161. It desired, additional co-mixing or vaporizing members may -be used in addition to the present device, but. inasmuch as these form ing flooded and inoperative.

Having thus described my invention it is obvious that various immaterial modications may be made in the same Without departing from the spirit ot my invention, hence I do not wishto be understood as limiting myself to the exact construction, arrangement or combination of parts herein shown or described or uses mentioned.
