Others have tiltable, object-carrying plates on car riages dragged along by chains or ?exible belts, for instance. In the latter, the plate is mechanically tilted by cams or other mobile guides, interacting lever systems, or .other devices connected to rotate or pivot the plate about hinged support from the carriage. This system presents, however, some inconveniences. For one, it is very noisy, making the working conditions noxious for the operators. For another, cam plate tilting devices must overcome inertias, mechanical resistances and frictions, so that it becomes necessary to oversize both the carriage dragging devices which also operate the plate-tilting devices and the support structures. This results in higher costs and uses greater ?oor space. Yet another lies in the considerable wear they are subjected to, so that they should be frequently repaired or kept up. In order to obviate the above inconveniences, the present invention provides a carriage for a transport and sorting apparatus equipped with independent means for causing its plate to tilt, preferably an electric motor or the like linked to the plate and fed e.g., by sliding contacts and feed rods at both sides of its path. In this manner, quick, precise and silent operation is obtained, and it is possible to properly size both the support struc tures and the carriage dragging devices. It leads to saving space and to a remarkable reduction of mainte nance operations. The present invention will be now described in detail, with special reference to the accompanying drawings, in which: FIG. 1 is a front view of part of a carriage according to the invention; FIG. 2 is a side view of the carriage of FIG. 1, partly in section; FIG. 3 is an enlarged rear view of a portion of the carriage of FIG. 1; FIG. 4 is the perspective view of the carriage of FIG. 1; FIG. 5 is an enlarged perspective view of a front portion of the carriage of FIG. 1; 5 25 30 35 45 55 65 FIG. 6 is a perspective schematic, exploded view of another carriage
