CARBURETGR.

" Application filed m 15, 1924. Serial No. 726,152.

This invention relates to carburetors and has particularreference to an improved construction of venturiv so as to insure a swirling action'of the gas to bring about 6 a more perfect atomization, a better combustion, and a minimum of fuel necessary to operate the en ine.

A further object is to provide a venturi with inclined. or tapering blades or vanes 1 extendingthroughout its length and past the waistline of the venturi.

This invention is particularly 'designedas an improvement upon the construction set forth in my pending application,- Serial No. 704,241, filed April 4, 1924. v I

With theseand other objects in view, the invention consists in certain novel features of construction and-combinations and arrangements of parts which will be more fully hereinafter described and pointed out in the claim. y

Inthe accompanying drawings- Figure 1 is a view partly in section and partly in elevation illustrating my invention;

Figure 2 is a view in transverse section on the line 2-2 of Figure 1;

Figure 3 is a view in transverse section 'on the line 38 of Figure 1. 1 represents. a carburetor of any approved constructiomflit being-understood that the carburetor shown is ;for purposes of illusi tration only and specifically has nothing whatever to do with, the invention except to 'which my. improved venturi 2 is located in the outlet passage 3 of the carburetor.

4 represents a no zzl e having a suitable" needle valve 5 wluch'dischargesthe properillustrate a simple form of carburetor in v 'Inside of the venturi and fixed to the walls thereof I provide a circular series of inclined blades or vanes 7 which extend from one end to the other of the venturi past the waistline. These blades or vanes 7 are widest at their respective ends and narrowest at the waistline of theventuri so that their inner edges are comparatively in straight lines and preferably these inner edges converge from the lower to the upper end of the venturi, as clearly illustrated in Figure '1 By providing said blades or vanes extending throughout the length of the venturi past the waistline, a swirling action is insured not only within the venturi but also as the gas leaves the venturi, and by reason of this action improved gas isinsured with 'a minimum of fuel consumption.

It isof course to be understood that the invention is not limited to any particular number of blades or vanes, but I believe three to be preferred number although this maybe varied to suit the trade.

Various slight changes and alterations might be made in the general form of the 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 slight changes and alterations as fairly fall within the spirit and. scope of the appended claim.

, I-claim: I

A carburetor including a venturi having a restricted portion between its ends, a noz zle located centrally in the venturi and terurinating at the restricted portion of the venturi, and a circular series of inclined straight blades projecting inwardly from the wall of the venturi and throughout the length of the venturi, said blades being angularly disposed relative to the axis of the venturi and having straight inner edges spaced from the nozzle, the inner edges of 1 the adjacent blades converging from the lower to the upper end of the venturi..
