  • Patent number: 4478198
    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.

  • Patent number: 4275981
    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.
