Ara-INLET DEVICE.

Patented Aug. 19, 1919..

Application filed February 12, 1917. Serial No. 148,055.

To'all whom it may concern:

Be it known that I, ARTHUR A. CRUSIUS, a citizen of the'United States of America, residing at New York city, Manhattan borough, county and State of New York, have invented certain new and useful Improvements in Air-Inlet Devices for Internal Combustion Motors, of which the following is a full, clear and exact description.

Thisinvention relates to a device for the admission or introduction of air to the combustible mixture created in the mixing chamber of the carbureter of an internal combustion motor; in other words, my improved device, which consists partly of an auxiliary a1r-inletvalve, is arranged to permit air to be drawn into the duct through which the combustible mixture is drawn by the suction of the pistons of a motor. The device also includes a perforated chamberarranged. for insertion, into the passage through which the combustible mixture,

passes. The said chamber can be inserted into the neck of a carbureter, or carried by a gasket-plate to be inserted between the flange of a carbureter and the flange of an intake -manifold, the valve being in communication with said chamber. The erforated chamber is arranged to admit air in proportion of the speed of the motor; Inv other words, at low speed the motor will draw less air than at high speed. The combined area of the openlngs in the chamber will be sufficient to admit the maximum amount of air required. The amount of air drawn through the openings in the chamber will be dependent upon the speed of the motor. I

I will now proceed to describe my invention in detail, the novel features of which will be summarized in the appended claims, reference beinghad to the. accompanying drawing, forming part hereof, wherein- Figure 1 is a diagrammatic side-view of a portion of a carbureter and intake-manifold, my improved device being illustrated as inie l'tied between the carbureter and mani- Fig. 2 is a similar view, illustrating the device as applied directly to the neck of a carbureter, the manifold being omitted;

Fig. 3 is an enlarged detail view illustrating a gasket-plate having applied thereto my improved auxiliary air-chamber and a valve in communication therewith; and

Fig. 4 is an enlarged fragmentary sec- .tional detail view, the section being taken on a line H in Fig. 3.

As herein embodied my inventlon consists of a chamber 5, which I term the auxiliary air-chamber, which is preferably inserted in the passage or opening 6 of a gasket-plate 7 to be inserted between the flange 8' of a carbureter 9 and the flange. 8 of an intake manifold 10,'as shown in Fig. 1, or into the neck of said carbureter, as in Fig. The device is equally eflicient in both instances, the gasket-plate being employed on account of ready attachability to carbureters already installed. I The invention resides chiefly ,in the combination of elements re gardless of point of attachment but, as be- 1' preferably employ a gasketof the motor-pistons, a ball-valve in this instance being employed to-close the duct 15. To regulate the vertical movement of the valve 16 I employ a screw-threaded spindle 17. A duct 18 places the chamber 14 in communication with the chamber 5. The chamber 5 comprises (in this instance) a substantially semi-cylindrical hollow rin 19 havin slots or openings 20 in the wall thereof, sai

openings being directed toward the center of v the ring orduct through which the combustible mixture passes on its way to the motor. The ring or chamber 5 (as is evident) is located in the central opening 6 of the plate 7, or may be located directly in the neck of the carbureter, the wall of said opening in the said plate. or in the neck of the carbureter forming the outer wall of the bore 21 of the chamber. g

It is quite evident that the suctionof the motor will draw air. throu h the slots 01' openings 20 to be mixed with the mixture drawn from the carbureter. At slow 5 eed air will be drawn in through some 0 the openings 20; in other words, the suctionof the motor, at slow speed, will not be great enough to fill the bore of the chamber 5 with air drawn in through the valve 12 and the air drawn in will very likely be drawn in through those openings adjacent the duct 18. At high speed, however, air will be drawn into chamber 5 through all of the openings 20 and hence will be thoroughly mixed withthe combustible mixture drawn from the carbureter.

As stated, a greater speed of the motor will correspondingly increase the indraft of air and will bring more of the openings 20 into play. The air thus drawn in is subjected to frictional resistance from the walls of these openings to a much greater extent than if entering through a single tube or passage of capacity equal ,to that of the aggregate of said small inlets. This will have a certain braking effect increasing with the speed of the motor and the number of such openings brought into use, and such braking will make for steadiness, preventing sudden changes of speed from causing irregular action and obviating all disadvantage by disturbance of the valve in its functions due for example to running over rough roads.

What I claim as my invention is:

1. An auxiliary air inlet for internal combustion engines, an intake duct for the engine, a. ring U shaped in cross section and snugly fitting within the intake duct forming between the wall of said duct and said ring an annular chamber, ports in said ring leading from the chamber to the intake duct and an inlet through the Wall of said duct communicating with said chamber.

2. An auxiliary air inlet for internal com bustion engines, comprising a gasket-plate having a central passage therethrough and a ring U shaped in cross section snugly fitti-ng Within the gasket-plate opening and forming therein an annular chamber, said ring provided with a plurality of openings leading from the chamber to said central passage anclan inlet leading to said chamher.

3. An auxiliary air inlet for internal combustion engines, comprisin a asket-plate having a central passage t erethrough and a ring U shaped in cross section snugly fitting within the gasket-plate opening and forming therein an annular chamber, said ring provided with a plurality of radially arranged slotted outlets leading from the chamber to the central passage and a single inlet leading to said chamber.

Signed at New York city, N. Y., this 10th day of February, 1917.
