Abstract
Abstract Disclosed is an attachment for insertion between the carburetor and intake manifold or firing chamber of an internal combustion engine which utilizes one or more solid conical members, having a series of axial and semi-radially directed apertures through which the gas-air mixture leaving the carburetor is forced thereby increasing the turbulence and homogenization of the air-gas mixture before it is introduced into the engine.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
An apparatus adapted for insertion between the carburetor and the intake manifold of an internal combustion engine, said apparatus comprising a generally flat base and at least one solid conical member depending from one face of the base, the other face of the base being undercut in register with the depending conical member, a series of spaced apertures extending through said conical member parallel to the axis of the member, a central aperture of larger diameter than said first mentioned spaced apertures coincident with the axis of the conical member and extending adjacent to but not through the apex of said conical member, and a further series of spaced apertures extending to the exterior of the cone shaped member from said central aperture, said further series of spaced apertures being adjacent the apex of said cone shaped member and extending at an acute angle with the axis of the cone shaped member.
Claim 2
Independent Claim
152 words
An apparatus adapted for insertion between the carburetor and the intake manifold of an internal combustion engine, said apparatus comprising a generally flat base and at least one solid conical member depending from one face of the base, the other face of the base being undercut in register with the depending conical member, a series of spaced apertures extending through said conical member parallel to the axis of the member, a central aperture of larger diameter than said first mentioned spaced apertures coincident with the axis of the conical member and extending adjacent to but not through the apex of said conical member, and a further series of spaced apertures extending to the exterior of the cone shaped member from said central aperture, said further series of spaced apertures being adjacent the apex of said cone shaped member and extending at an acute angle with the axis of the cone shaped member.
Claim 3
Dependent Claim
31 words
An apparatus as claimed in claim 1 in which said base has depending from it two identically apertured conical members thereby adapting the apparatus for use with a two barrel carburetor.
Claim 4
Dependent Claim
23 words
An apparatus as claimed in claim 1 in which the acute angle of extension of said further series of apertures is approximately 50°.
