982,200. Road vehicle bodies and trailers. FRUEHAUF CORPORATION. Nov. 26, 1962 [Nov. 27, 1961], No. 44644/62. Heading B7B. A wheeled chassis 12, Fig. 1, which may be attached to a container 14 through which the tractive effort passes, comprises a ramp 10 downwardly foldable on links 42, 44, as in Fig. 3, and adapted to engage between pins 18, 20 on another container 16 so as to align the two containers when coupling. The ramp is provided with a downwardly inclined face 32 which effects vertical gathering of the containers, and forwardly convergent side faces 34, 36 which coact with the pins and provide lateral gathering. After alignment the containers are coupled together by connecting links 40 as in Fig. 2. In a modification, Fig. 4 (not shown), the ramp is provided with forwardly converging side faces 112, 114 and with a V groove, which ramp engages either with a single central pin on another container or with two pins such as 18 and 20. In a further modification, Fig. 5, the ramp comprises a pair of vertically pivoted projections 220, 222 mouned on a trailer or vehicle chassis 202, and engages pairs of pins similar to 18, 20 as before. A recess 250 is provided at the other end of the chassis to accommodate a ramp on another vehicle.
