Application filed March 30. 1925, Serial No. 19 307.

This invention relates to auxiliary mixing devices for engine intakes and particularly relates to devices of this character, adapted to be clamped between the carburetor and intake manifold.

An object of the invention is to provide a plate adapted to be clamped between a carburetor and intake manifold and having an opening for registration with the mixture passage of said carburetor and manifold, and further having a battle member projecting into said opening and an inlet to said opening upon the carburetor side of said bafiie, the latter being adapted in the use of said device to intercept the heavier particles of fuel traveling in the lower portion of the mixture passage and to break up said particles and commingle the same with the supply of auxiliary air entering said opening by way of said inlet.

Another object is to provide a plate of the described character comprising a sheet of metal and a sheet of fibre or the like, the

two said sheets being secured together in a.

unitary relation and a battle member being formed integrally with the sheet metal memher while the fibre member is formed with a passage for the admission of auxiliary air.

These and various other objects are attained by the construction hereinafter described and illustrated in the accompanying drawing, wherein:

Figure 1 is a view in end elevation of an internal combustion engine showing the herein described auxiliary mixing device installed.

Figure 2 is an enlarged sectional view of the joined portions of the intake manifold and carburetor showing how the mixing device is clamped between said portions.

Figure dis a perspective view of the air mixing device.

In these views the reference character 1 designates an internal combustion engine, 2, the intake manifold thereof, and 3 the carburetor of said engine. The adjoining ends of said manifold and carburetor are commonly clamped together by suitable bolts 4, engaging flanges 5 formed respectively upon said ends.

In accordance with the present invention, the bolts l are employed not only to connect the carburetor to the intake manifold but also to clamp between the adjoining ends thereof, an auxiliary air mixing or carbureting device, such as is shown in Figure 3.

Said device comprises a sheet metal plate 6, preferably formed of copper and a plate 7 formed of fibre or other suitable nonmetallic sheet'material. Said plates are formed with central openings 8 which, in the position of use of the mixing device,

register with the mixture passages of. the

carburetor and intake manifold, and the metal plate 3 is integrally formed with a battle member 9, which projects upwardly into the opening 8 of said plate, obstructing the lower portion of said opening. The two said plates are connected together in a unitary relation by the formation upon the plate 6 of marginal lu s 10 which are bent to embrace the plate 7, as Fig. 3 clearly shows. The fibre plate 7 is considerably thicker than the plate 6 and is formed with an opening, radial to the opening 8, receiving a metal tube 11 and functioning for the admission of an auxiliary supply of air to the mixture passage. The L1 per edge of the baflle member 9 is arcuately curved, the are formed by said edge being preferably centered at the outlet of the tube 11, so that the air incoming through said tube radiates fanwise, and flows to a substantially equal extent over all portions of the baffle member.

In the use of the described device, the heavier particles of fuel, flowing through the lower portion of the mixture passage, encounter the baffle member 9 and at the same time encounter the rising current of auxiliary air admitted through the tube 11. The effect of the impact of this encounter is to break up said particles, to cause their-intimate association with the auxiliary air, so that the mixture flowing onward from the battle is finely divided, well mixed, and highly explosive. c

The described two-part construction of the device is desirable, since the sheet metal member of the device supports and properly positions the battle member in a simple and inexpensive manner, while the non-metallic member serves as the sole support for the air inlet tube, at the same time protecting said tube from being crushed or deformed under the clamping stress applied to hold the device positioned for use. Also said nonmetallic member is sufficiently yielding to properly seal the joint between the carburetor and intake manifold.

A desirable feature of the operation of the described device is a heating effect to which the batfie member is subjected by the velocity of the flow of auxiliary air adjacent to said member, the heat thus induced in said memher being finally given off to the mixture and increasing the efiiciency of the latter.

hat I claim is:

1. An auxiliary air inlet and mixing device comprising a sheet metal plate and a thicker plate of relatively yielding material, the sheet metal plate being formed marginally'with lugs embracing the non-metallic plate and establishing a unitary connection between the two plates, the two plates being further jointly formed with an opening for registration with the mixture passage 01 a carburetor and manifold between which said device is adapted to be clamped, said sheet metal plate having an integral battle member projecting into said opening, and said thicker plate being formed with a passage delivering auxiliary air into said opening in the vicinity of said baffle.

2. An auxiliary air inlet and mixing device adapted to be clamped between the intake manifold and the carburetor of an internal combustion engine, comprising a sheet metal plate and a thicker plate of relatively yielding material secured to each other in a unitary relation and jointly formed with an opening for registration with the mixture passage of said manifold and carburetor, a battle member carried by said sheet metal plate adapted to obstruct the lower portion of said opening, and a tube mount-ed in said thicker plate and extending from the outer edge of said plate to said opening, communicating with said opening adjacent to the lower portion of said battle for admitting auxiliary air to said opening.

In testimony whereof I sign this specification.
