Abstract: A trailer for hauling vehicles includes a central frame with a pair of longitudinal tubular members and a plurality of transverse tubular cross-members interconnecting the longitudinal members to form an open frame. A pair of ladder frames are affixed along the longitudinal outward faces of the longitudinal members and project transversely therefrom in opposite directions. Each transverse ladder frame includes an outer rail extending parallel to the longitudinal members, and a plurality of rungs connecting the outer rails to the longitudinal members. A pair of tread plates are supposed on the ladder frames and extend from the forward to the rearward end of the frame, the tread plates spaced-apart a distance to support the wheels of a vehicle thereon. A wheel assembly is mounted on the frame to permit transport of the trailer, and a hitch is mounted on the forward end of the frame to permit connection to a pickup or other prime mover.

Abstract: A twin air valve carbureter has a single bar which extends diametrically across the two draught tubes upstream thereof, and two air valve flaps which are mounted on opposite sides of the bar, so as to extend across both draught tubes, and are hinged at their ends remote from the bar. Both the flaps co-operate with the bar to define a throat of variable area. The fuel discharge ports are formed in the bar and comprise outwardly-divergent slot ports. A depression responsive fluid pressure motor is linked to each of the flaps to provide compensation for the effect of the reduction of the effective area of each flap as that flap opens. A novel linkage is disclosed for linking a fuel metering needle to one of the flaps.
