UNITED STATES EDWIN G. HAMILTON, OIE ANN ARBOR, MICHIGAN.

FUEL MIXER.

Application filed. June 8,

My invention relates to improvements in devices which are adapted to produce a thorough mixture of the fuel passing through the intake passage of an internal com-- bustion engine, and it is the object of the invention to provide a device of this class which is of extreme simplicity, yet will be highly eflicient, will thoroughly mix the fuel from the spray nozzle of the carbureter, and will cause the wall of the intake passage to be substantially lined with air, so that thereis no danger of fuel condensing on said wall, with the well known disadvantages.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

*igure 1 is a plan View showing my invention embodied in an insert adapted to be secured between a carbureter and an intake manifold.

Figure 2 is a vertical longitudinal seetional View of the insert secured in place Fig. 3 is a vertical transverse sectional view as indicated by line 3-3 of Fig. 1.

In the drawing above briefly described, which illustrates the preferred form of my invention, the numeral 1 designates a sheet metal plate adapted to be secured between a carbureter outlet neck 2 and an intake manifold 8, by the usual bolts 4:. This plate is formed with a substantially circular opening 5 and is provided with a pair of opposed wings 6 which extend into said opening. These wings are provided with relatively narrow outer ends and said wings are enlarged toward their inner ends, the latter being preferably straight and spaced a slight distance apart to form a slit-like fuel passage 7. Both wings are bent into transvertely arched form and the crown portions thereof incline toward each other. The

' edges 8 of the wings are preferably curved and these edges are spaced inwardly from the edge wall of the opening 5, to provide a pair of relatively wide, crescent-shaped air passages 9, said edges being preferably 1925. Serial No. 35,728.

in the same plane with the body portion of the plate 1, as shown.

When the invention is in use, the spray of fuel from the nozzle of the carbureter strikes the wings 6 and is by them drawn inwardly away from the wall of the intake manifold, the fuel being released through the slit 7 which insures thorough mixing thereof. While this mixing is taking place, substantially fuel-free air passes through the passages 9 and, forms substantially a continuous lining for the interior of the manifold, so that the fuel will not strike the latter, condense thereon, and produce undesirable results' I have found that by the use of my invention, I am enabled to effect a saving in fuel and furthermore, due to the excellent combustion which is produced in the engine cylinders, there is practically no deposit of carbon.

The details shown are preferably followed, but within the scope of the invention as claimed, it is of course possible to incorporate the wings 6 in the fuel intake passage of a motor, by mounting said wings in some other way, instead of upon an insert or plate, as herein shown.

I claim i 1. In a fuel'mixer of the type described, a member having a fuel mixture passageway, a pair of opposed wings projecting into the passageway from the walls of the latter, said wings having relatively narrow outer ends and being enlarged from said outer ends to their inner ends, being transversely arched and having their crown portions in clined toward each other, the inner ends of said wings being disposed in slightly spaced relation with each other to provide a slitlike fuel passage, the side edges of said Wings being inwardly spaced from the wall forming the passageway to provide two substantially crescent-shaped fuel mixture passages at the ends of said slit like passage.

2. A fuel mixer comprising a plate adapted to extend across the fuel intake passage of an internal combustion motor, said plate having an opening of substantially circular relation with each other to provide a slitlike fuel passage, the edges of said wings 10 being spaced inwardly from the edge walls of the opening to provide two substantially crescent-shaped fuel mixture passages.

In testimony whereof I have hereunto af fixed my signature.
