Abstract
Abstract This vaporizer device is for connection between the carburetor outlet and the manifold inlet of a combustion engine. It comprises a conduit for receiving the air-fuel mix from the carburetor and for flow of the mix through the conduit which has a plurality of smooth fingers operatively positioned in the conduit normal to the flow path of the air-fuel mix, and a means connects to the conduit to receive the air-fuel mix therefrom. Such means includes a housing having a driven center shaft suspended therein and provided with a fan member at its lower end. A plurality of radially extending arms or fingers are carried by the shaft at axially spaced portions thereon and a second set of arms or fingers is secured to the housing and extends radially inwardly therefrom with the arms of the different sets being interleaved with each other for further agitation of the fuel-air mix as it moves through such means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
178 words
A device for improving the fuel-air mixture for a combustion engine and comprising a conduit for connection to a carburetor to receive an air-fuel mix therefrom, said conduit having a number of fingers operatively positioned therein normal to the path of flow of the air-fuel mix to aid in breaking up any liquid fuel particles carried by the air-fuel mixture, and a means connected to said conduit to receive the air-fuel mix therefrom and including a vertically positioned housing, a driven center shaft suspended in said housing and having a fan member secured to its lower end to aid in drawing the air-fuel mix down through the housing, a set of radially extending fingers carried by said shaft in axially and circumferentially spaced positions thereon, a second set of fingers secured to said housing and extending radially thereof and positioned axially intermediate the members of the first set of fingers to agitate the air-fuel mixture and further break up any liquid fuel particles; the lower end of said housing being connectable to a manifold of a combustion engine.
Claim 2
Independent Claim
178 words
A device for improving the fuel-air mixture for a combustion engine and comprising a conduit for connection to a carburetor to receive an air-fuel mix therefrom, said conduit having a number of fingers operatively positioned therein normal to the path of flow of the air-fuel mix to aid in breaking up any liquid fuel particles carried by the air-fuel mixture, and a means connected to said conduit to receive the air-fuel mix therefrom and including a vertically positioned housing, a driven center shaft suspended in said housing and having a fan member secured to its lower end to aid in drawing the air-fuel mix down through the housing, a set of radially extending fingers carried by said shaft in axially and circumferentially spaced positions thereon, a second set of fingers secured to said housing and extending radially thereof and positioned axially intermediate the members of the first set of fingers to agitate the air-fuel mixture and further break up any liquid fuel particles; the lower end of said housing being connectable to a manifold of a combustion engine.
Claim 3
Dependent Claim
60 words
A device as in claim 1 where said housing is tubular and has several steps of increased internal diameter from the top to the bottom thereof, and said fingers of said sets are longer at lower portions of said housing with the fingers of said first set being of lengths to end immediately adjacent the inner wall of said housing.
Claim 4
Dependent Claim
33 words
A device as in claim 2 where said sets of said fingers extend the length of said housing with the fingers of said sets being uniformly spaced radially and axially of said housing.
Claim 5
Dependent Claim
20 words
A device as in claim 1 and including said conduit being connected to an upper side portion of said housing.
Claim 6
Dependent Claim
26 words
A device as in claim 1 and where said conduit is of rectangular shape in cross section and said fingers extend the height of said conduit.
Claim 7
Dependent Claim
20 words
A device as in claim 1 and comprising said fingers being formed on a member removably carried in said conduit.
Claim 8
Dependent Claim
41 words
A device as in claim 1 and where said means has an inlet end and an outlet end and said fan is adjacent the outlet end to aid in drawing the air-fuel mix into and through said conduit and said housing.
Claim 9
Dependent Claim
17 words
A device as in claim 1 and including said shaft having variable speed drive means connecting thereto.
