Claim 2

A CARBURETOR COMPRISING, IN COMBINATION: A HOUSING DEFINING AN INDUCTION THROAT, A PLATE DISPOSED ROTATABLY IN THE INDUCTION THROAT, A BRACKET DISPOSED ON THE PLATE, THE BRACKET INCLUDING A PAIE OF PROJECTING EARS, EACH EAR HAVING A CIRCULAR OPENING THERETHROUGH, THE CIRCULAR OPENINGS BEING COAXIAL, A PLATE-FOLLOWING LINK HAVVING A CYLINDRICAL PIN PROJECTINF THEREFROM THROUGH THE CIRCULAR OPENINGS, A BUSHING INCLUDING A GENEALLY CYLINDRICAL SLEEVE EXTENDING THROUGH THE CIRCULAR OPENINGS AROUND THE PIN, ONE OR MORE STOPS ST THE END OF THE SLEEVE ADJACENT THE LINK, THE STOPS BEING ENGAGEABLE WITH THE PLATE TO PREVENT ROTATION OF THE BUSHING WITH RESPECT THERETO AND FURTHER ENGAGEABLE WITH THE EAR ADJACENT THE LINK TO PRE-

Claim 3

A carburetor comprising, in combination: a housing defining an induction throat; a plate disposed rotatably in the induction throat; a bracket disposed on the plate, the bracket including a pair of projecting ears, each ear having a circular opening therethrough, the circular openings being coaxial; a plate-following link having a cylindrical pin projecting therefrom through the circular openings; a bushing including a generally cylindrical sleeve extending through the circular openings around the pin, one or more sector-shaped stops radiating from the end of the sleeve adjacent the link, the sector-shaped stops having peripheral edges with a radius greater than the distance between the axis of the circular openings and the plate and being engageable with the plate to prevent rotation of the bushing with respect thereto and with the ear adjacent the link to prevent withdrawal of the bushing from the circular openings in one direction, the bushing further including one or more projecting members being deformable to pass through one of the circular openings upon insertion of the bushing therethrough but engageable with the ear adjacent the link to prevent withdrawal of the bushing from the circular openings in the other direction, the end of the bushing opposite the link including a plurality of inward tapering fingers to assist insertion of the bushing through the circular openings; and means provided for the pin near its end opposite the link for engaging the tapered fingers to prevent the withdrawal of the pin from the bushing.

Claim 4

A carburetor comprising, in combination: a housing defining an induction throat; a plate disposed rotatably in the induction throat; a bracket disposed on the plate, the bracket including a pair of projecting ears, each ear having a circular opening therethrough, the circular openings being coaxial; a plate-following link having a cylindrical pin projecting therefrom through the circular openings; a bushing including a generally cylindrical sleeve extending through the circular openings around the pin, one or more sector-shaped stops radiating from the end of the sleeve adjacent the link, the sector-shaped stops having peripheral edges with a radius greater than the distance between the axis of the circular openings and the plate and being engageable with the plate to prevent rotation of the bushing with respect thereto and with the ear adjacent the link to prevent withdrawal of the bushing from the circular openings in one direction, the bushing further including one or more projecting members being deformable to pass through one of the circular openings upon insertion of the bushing therethrough but engageable with the ear adjacent the link to prevent withdrawal of the bushing from the circular openings in the other direction, the end of the bushing opposite the link including a plurality of inward tapering fingers to assist insertion of the bushing through the circular openings; and means provided for the pin near its end opposite the link for engaging the tapered fingers to prevent the withdrawal of the pin from the bushing.
