Abstract: A housing has an inlet arranged to be connected to the outlet of a fuel mixing device of an internal combustion engine such as a carburetor and an outlet arranged to be connected to the intake manifold of the engine. In a preferred embodiment of the invention, the housing has two or more spiral bores. These bores have a cross sectional area less than the cross sectional area of the outlet of the carburetor to provide increased time and velocity through the spiral bores and to isolate the carburetor from vacuum pulsations of the engine. The defining surfaces of the spiral bores is roughened to increase atomization. A second embodiment utilizes an elongated housing also having a spiral path for mixing the fuel and air.

Abstract: A first body member is arranged to be secured on a vehicle and has an outwardly facing socket. A second body member is provided, and this member has an inwardly facing socket. A connecting neck has opposite ends arranged to be received in the sockets of the first and second body members, the neck in one embodiment being straight to provide a straight hitch on a vehicle and the neck in another embodiment having a vertical body portion and oppositely extending ends to provide a drop hitch. The second body member has a pair of hitch coupler portions on opposite surfaces thereof, and this body member has a pair of adjusted mounted positions on the neck so that one or the other of the hitch coupler portions can be used conveniently.

Abstract: A pair of support arms are arranged for attachment to a vehicle, and a channel-shaped ramp is arranged to seat on these arms for holding a motorcycle. This ramp has a pivot connection with one arm and extends beyond such pivot connection in a direction opposite from the other arm whereby upon tilting the ramp off the other arm, a motorcycle can be wheeled up the ramp to a point such that the combined centers of gravity of the motorcycle and ramp will cause the latter to pivot down into support on the other arm. A releasable latch is provided to hold the ramp down in a non-pivoting position. The ramp has a depending loop for removably receiving an auxiliary ramp which forms an extension thereof. The present carrier may be associated with various types of support means on a vehicle such as support means arranged for mounting on a bumper, bumper guard or support means combined with a spare wheel mount.
