5. M. PERFECT V 7 AIR FEED DEVICE I Filed Sept. 15. 1922 Patented Sept. 4, 1923.

UNITED s AIR-FEED, DEVICE,

Application filed September 15, 1922. Serial No. 588,435.

To all whom it may concern:

Be it known that I, EBL'R M. PERFECT, a citizen of the United States, and a resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and Improved Air-Feed Device, of which the following is a full, clear, and exact description.

This invention relates to improvements in air feed devices, and more particularly to an attachment for internal con bustionengines which insures a feed of air into the intake manifold in the engine in propor tion to the feed of fuel from the carbureter, an object of the invention being to 'provide a device of the character stated which results in an economy of fuel consumption so that increased mileage may be had from given quantity of gas, to insure a more perfect combustion, to increase the power of the engine, and to insure a complete burning of the mixture and prevent or'reduce toa minimum the liability of carbonformation in the engine head. I v

A further object is to provide an attachment, of the characterv stated, which ca fbe manufactured and sold at -a11 extremely low price, which can be placed in operative position without altering or injuring. the construction of the engine and carbureter, and which can be installed by anyone of average intelligence not requiring skilled labor.

A further object is to provide a device of the character stated which is operated by the throttle lever as the latter moves the throttle of the carbureter so that the mixture of fuel and air is automatic and properly proportioned. a

A further object is to provide a device of the character stated which enables th min troduction of water into the intake manifold to. generate steam and burn'carbon forming in the, engine head.

Withthese and other objects in view, the invention consists in certain novel features of construction and combinations and arrangement of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a fragmentary plan view illustrating my improved device in operative position.

. Figure 2 is a view in transverse section on the line 2-2, of Figural.

Figure 3 is a view similar to Figure 2 but showing a water pipe connected to the air inlet port for supplying water to burn carbon as will more fully hereinafter-appear.

1 represents a carbureter and 2 the intake manifold of an internal combustion engine. stitutes the body portion of my improved attachment or device, and which is located between the flanges 4 and 5 of the carbureter and manifold respectively,- t11Cl lS111%LCl(-) with openings 6 to receive the bolts 7 which are projected through the flanges 41:" and 5 and secured bynuts 8 tofirinly in the block in a position between the flanges. i

It will thus be noted that the attach- 'ment can be positioned without altering the structure as in use and hence can be readily lnserted by 'slmply' removing the 3 represents a block which con ordinary bolts and connecting as above explained.

Block '3 is made with a central opening 9 registering with the outlet of the'carb n.

reter and the bore of the intake'toi permit a free passage of fuelto the engine; 10 represents the throttle arm and 11 the rod connecting the arm 10 with the ordinary accelerator lever of' the car. f

This arm 10 extends across the block 3 and is locatedunder a lever 12. This lever 12 is provided at one end with a pair of perforatedears 13 for the reception of a bolt 14: projected through the block 3 and secured by means of a nut 15 to provide a pivotal connection for the lever. A depending lip 15 is formed on the leverto engage the end of the block? and limit the pivotal movement of the lever in one direction. I

Thelever 12functions tocontrol the posi tion of an air inlet valve 16 which latter'has a beveled seat 17 at the outer endof an inlet port 18 which communicatesfwith the portion engages in the groove 20 and compels the valve to move with the lever. The enlarged outer end 21 of the valve prevents possibility of accidental disconnection of the lever and the valve.

The lever 12 is bent forming a cam 23 which is engaged by the throttle arm 10 so that when the arm 10 is moved in a direction to open the throttle, it will engage the cam portion 23 and pivot the lever 12 in a direction to open valve 16 so that the valve 16 will be opened in proportion to the opening of the throttle, and admit air in proportion to the fuel. As the throttle is closed the suction of the engine will draw the valve 16 toward closed position so that in manipulating the throttle, the position of the valve is also controlled so as to insure a proper proportion of air in accordance with the feed of fuel.

To remove carbon from the engine, it is simply necessary to remove the lever nd the valve 16 and insert a water pipe 24 into the port 18 and allow the suction of the en gine to draw water therein which generates a steam and burns the carbon or dislodges the same and causes the particles of carbon to be discharged through the exhaust of the engine.

In illustration of Figure 1 I show my device as attached to the ordinary type of carbureter of a Ford engine, as I have. found that the device is particularly adapted for use in connection with engines of this type although it is of course, to be understood that the invention is not limited to any particular type of engine or automobile, as it may be used in connection with any form of engine and capable of modification as to structural details in order to properly function in its location or position. The valve is shown as seating by gravity aided by suction of the engine, but it is obvious that if the valve were otherwise located it would be desirable to assist the closing or opening movement by employing any desired mechanical means.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. A device of the character described,

.nected to the block and having a cam comprising a block having fuel passage therethrough, and an air inlet port communicating With said passage, a lever pivotally conportion adapted to be engaged by the throttle arm of an engine, said lever having a key hole slot therein, a valve seating in the port and having an annular grove receiving the narrower portion of the slot, and a stem on the valve projecting into the port.

2. The combination with a carbureter, an intake manifold and throttle arm controlling the fuel outlet of the carbureter, and means for moving the arm, of a block secured between the carbureter and the manifold, and having a fuel passage thercthrough and also having an air inlet port communicating with the passage, a lever pivotally connected to the block, a cam face on the lever engaged by the arm. whereby the lever is moved in exact accordance with the position of the arm, and a valve connected to the lever and controlling the entrance of air through said port.

3. The combination with a carbureter, and an intake manifold, of a block secured between the carburete-r and the manifold and having a fuel passage therethrough, said block having an air inlet communicating with the said passage, a lever pivotally connected to the block, a valve carried by the lever and normally closing the air inlet passage, said lever having a cam portion, and a throttle lever controlling the exit of fuel from the carbureter, said throttle lever engaging the cam portion of the first mentioned lever whereby the operation of the throttle automatically controls the movement of the air inlet valve.

4. The combination with a carburetor, and an intake manifold, of a block secured between the carbureter and the manifold and having a fuel passage therethrough, said block having an air inlet communicating with the said passage, a lever pivotally connected to the block, a valve carried by the lever and normally closing the air inlet passage, said lever having a cam portion. and a throttle lever controlling the exit of fuel from the carbureter, said throttle lever engaging the cam portion of the first mentioned lever, whereby the operation of the throttle automatically controls the movement of the air inlet valve, and means on the first mentioned lever engaging the block and limiting its pivotal movement.

EBER M. PERFECT.
