King and State of Washington, have in- 'Y 'vented certain new andv useful Improvements ICE.



Application-med July 2, 1919. serial No.

To all whom t may concern.'

Be it known that I, FRED N. LIvIilrGs'roN,

acitizenof the United States, residing-at St., Seattle, in the county of in Fuel-Mixers; and I do following to be full, clear, and exact descripf tion of the invention, such as will enable others skilled in the art to which it apperhereby declare the tains 'to make and use the same.

This invention relates to screens for breakingp particles of gasolene or fuel oily for the purpose of better mixlng the same with air for burning, particularly for internal combustion engines v Great importance in operating gasolene v engines rests in theproper mixture of air and fine particles of gasolene or gaseous fuel, as the power of the engine on a given amount of gasolene or gas dependsrlargely on the amount of air that is nixed' before'the fuel is fired, and in order to secure. the best mixture it is necessary that the particles of oil be broken into the smallest parts possible and it is the object of my invention to produce a simple and effective apparatus that may be readily affixed between the ordinary carbureter andthe intake pipe of the englne and'which will cause the oil orfuel to b e broken up as desired and properly mixed with air,

Figure 1 is a top plan of my device, and

igure 2 is a side view of the same.

, My device consists of a constructed in size and form of an ordinary metal gasket to be held between the joints ofthe carburetor and intake pipe by means of the ordinary coupling bolts, passed provided .near the ends Speci-cation of Letters Patent.y

sheet l, of metal vhaving a hollow boss.

where they may terminate ina V Patented Feb. 14, 1922. 308,128.

The cutting out of these slots necessarily leaves wedge shaped sections or leaves 6 of the'body 3 etween the slots, and in these remainmg wed e sections I bore two or more holes 5, the ole in the wider part of the leaf being larger than the other, and these holes I make before the cone is pressed, preferably so that'the walls .of the holes are at right angles with the face ofthe body portion of the device, and then when the body 3 1s pressed into position, these holes and their walls will all divergein line from the walls v of the cone.

In use, the device is :placed in the proper position in the fuel intake'pipe, so that the gasolene or oilmust pass through the slots and holes, and in so passing the diverging walls of the holes and arrangement of the slots will cause the gasolene or oil to be sprayed in diverging and cross lines and broken up into a' finely gaseous mixture with air then supplied. The device is placed between the carbureter and the intake manifold, .with the top or convergent body toward the engine and away from the carbureter.

Having described my invention, I claim- 1. A mixing device comprising a plate adapted fuel-intake for vgasoline engines, said plate having a hollow boss projecting from its central portion, and said boss having radiatslots in its wall and holes between the s o s.

2. A mixing device comprising a plate adapted tobe clamped between sections of a fuel-intake for gasoline engines, said plate projecting from its central portion, said boss having radiating slots in its walls decreasing in width toward their outer ends, and a plurality of holes of different sizes between the slots so disposed that holes farthest from the center are larger than holes nearer :the center, the axis of the holes being normal to the local surface.

In testimony whereof I affix my signature. i
