Auxiliary air intake and mixing device

Application filed July 13, 1928. Serial No. 292,458.

This invention relates to auxiliary airintake and. mixing device for internal combustion motors and particularly relates to devices of this character adapted to be ϋ clamped between the carburetor and intake manifold.

The principal object of my invention is to provide a simple and inexpensive device designed to reduce the amount of gas used and 10 at the same time allow enough for energizing the motor. Another object of my invention, is to provide a device which causes the mixture after leaving the carburetor to be subjected to a dual whirling or . twisting moye15 ment, thereby more thoroughly atomizing and mixing the mixture with air before entering the motor.

With the foregoing and other objects, in view which will appear as the description 20 proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention 25 herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:—30 Figure 1 is a top plan view of the device.

Figure 2 is a side elevation of the device.

Figure 3 is a cross sectional view taken on line 3—3 of Figure 1.

Figure 4 is a cross sectional view taken on 35 line 4r—4 of Figure 1.

Figure 5 is a side elevation of the device properly inserted for use.

Figure 6 is an enlarged view of the screen member 15.

⁴⁰ In the drawing, 1 indicates a carburetor of any usual construction, 2 indicates a pipe leading from the carburetor to a manifold of usual construction. The carburetor 1 is pro₄₅ vided with an ordinary flange 3 and the pipe 2 is provided with an ordinary flange 4 and these flanges are usually secured together by bolts 5, so that a continuous passage from the carburetor to the manifold is formed, by 50 which the explosive mixture formed in the carburetor is delivered to the manifold and distributed to the engine cylinders.

Between the flanges 3 and 4,1 have inserted a plate 6, preferably of sheet metal constructed in such a manner as to cause a circular, twisting motion of the explosive mixture formed in the carburetor, and at the same time, provide means for inlet of air which is introduced into this circular, twisting mixture in a manner so as to strike this ex-. eo plosive mixture in a reversible motion from that of the motion of the explosive mixture formed in the carburetor.

By referring to Figure 1, it will be seen that the plate 6 is provided with openings ΐ tf for the reception of bolts 5, centrally located in the plate 6, there is provided a circular groove 8 provided with a plurality of inlet grooves 9 which connect to an outer edge 10 of the plate 6 and communicate with the an- 70 nular groove 8. Within this annular groove 8, there is provided a plurality of upturned curving and twisting lips 11. It will be seen that each of these lips 11 are symmetrical, each having a curved and twisted edge 12 75 and a relatively straight edge 13. It is obvious that when the explosive mixture is caused to flow through the openings formed by the lips 11, this mixture is given, a terrific whirling motion in an anti-clockwise move- 80 ment. Into this whirling flow of explosive mixture, air is allowed to enter through the grooves 9 which communicate with the annular groove 8 at a point 14 which is centrally located at base of each of the lips 11. 85 Due to the formation of the lips 11, the edge 13 is relatively lower than the edge 12 and therefore this inlet of air rushing up over the outer surface of the lips 11 encounters the anti-clockwise whirl of the explosive mix- ⁹⁰ture in a clockwise direction.

By referring to Figure 6, it will be seen that I have provided a screen member 15 which is placed within the inlet groove 9 for the _e6purpose of straining the air before the same enters into the pipe leading into the manifold.

It is obvious that with this extraordinary mixing of air with the explosive mixture, more desirable combustion will be produced 100
