, Application filed April 30, 1915. Serial No. 24,868.

To all whom it may concern: 4

Be it known that I, EMILE WAL MEIER, a citizen of the United States, and a resident of Gulfport, in the county of Harrison and- State of Mississippi, have invented an Improvement in Air-Regulators for Engine- Manifolds, of which the following is a specification. The present invention relates to gasolene engines and more particularly to an auxiliary valve attachmentassociated with the carbureter thereof and adapted to automatically regulate the quality of the mixture being supplied to the cylinders. x The primary object of the invention is the provision of a device attached to theimanifold of the engine and automatically operated by the inrush of air from the radiator and engine fan to increase or decrease the amount of air intake to the mixture in conformity with the speed of the engine,

A further object is to provide an attach-- ment of this character which may be appliedto' engines of ordinary construction and which is durable, efficient in carrying out the purpose for which it is designed and inexpensive to manufacture.

-' appended claimsfor this The inventive ideainvolved is capable of receiving a variety bf mechanical expres sions, some of which for the purpose of illustrating the invention, are shown in the accompanying drawing; .but it isto be ex-;

pressly understood that the. particular con.- struction shown in -the-drawing is used merelyitofacilitate the description of the invention as a whole, and not to define the limits thereof,- reference being had to the purpose. a 'In the "drawing Y Figure 1 isa diagrammatic'view of a gasolene engine showing the-invention applied 'thereto,

Fig. 2 is an enlarged 'viewof the" device showing-the same in its maximum-open position.

Referring more particularly to the accompanying drawing in which 1' e reference Fig. 3 is a section taken substantially on the line.33 of Fig. 4.

. reduced externally threaded end 16 of a connection 17 theouter end of which is enlarged as indicated at 18 and also provided with external threads. internally threaded cylinder 19 having an' open inner end is threaded upon the enlarged portion 18 of the connection 17 and adjusted thereon inv any desired position.

The top of the cylinder 19 -is enlarged as shown at 20 and has secured to this enlarged portion, by means of set screws 21, an angular bracket 22 having a depending portion 23 which extends in frontof the'outer end of the cylinder 19 and spaced a distance therefrom. The closed outer end of the cylindex 19 is provided with a centrally located opening in which is mounted a small bearing pin 24 extending longitudinally of the cylinder 19' and having its ends pointed as shown. The depending portion 23 of the alinement with. thebear'ing pin 24, adapted to receive; an adjusting'screw 25,'the inner Specification of Letters Patent. P t ted M 13, 1917 bracket 22 is provided with an opening, in

end of-which formsa bearing for the adjacent pointed end of said pin.. The cylinder 1.9 also'hasmounted therein a disk 26 which is adjustable-longitudinally of said cylinder and prbvided centrally thereof with an opening, in al'inement with thebearing pin 24, adapted to receive ascrew 27,-similar to screw '25, the inner end. of'which engages the adjacent pointed end of the pin 24.

The portion of the pin 24 projecting be yond the outer end-of the cylinder 19 has pivotally mounted .thereon an oscillating 'plate 28 'havingan 'arcuate slot 29'therein "which is adapted to register with a similar slot-30 inthe closedend .of the cylinder 19 when-the parts are' in the position shown in Fig. 2. The air is .then' permitted to .pass through said slots and openings 31 formed 13 where itmixes 1th the original mixture in the disk 26 and-thence into the manifold' 'l'l'o from the carbureter14. If desired a plurality of spacing rings 32 may be inserted into the cylinder 19 between the outer end thereof and the disk 26. The oscillating plate 28fis adapted to abut the outer end of the cylinder 19 and is provided with a relatively large vane 33 the plane of which extends at right angles to the plane of said plate. A spring 34 is coiled about the inner. end of the bearing pin 24 and has one of its.

ends secured in the cylinder 19 while the other end thereof is connected to a pin 35* whichprojects through the arcuate slot 30 in the cylinder 19 and has its outer end secured in the;plate 28. This spring 34 is adapted :to normally retain the vane in the position shown in Fig. 5 when the

slots

29 and 30 are out of registry. It will thus be apparent that the vane 33 is moved toward the position shown in Fig. 2 against the tension of the spring 34. r

In practice, when the engine is running at a normal or slow speed the inrush of air from the radiator and engine fan 11 is insufficient to overcome the tension of the spring 34 and move the vane 33 to the opening position. However, when the speed 'of the car and, engine is accelerated sufliciently to cause the pressure of air against the vane 33 to move the same toward the left, as shown in the drawing, the plate 28 will be oscillated about its pivot 24 untilthe arcuate slot 29 therein registers with the slot-30 in the cylinder. 19 when air will pass therethrough into the manifold, as previously described. If the pressure of air against the vane is sufiiciently strong the same will be tion through the medium of the spring 34.
