Abstract of Disclosure An unloading mechanism for a goods waggon for use in railway or road transports with a goods container having a cylindrical bottom and turnably mounted by its ends in bearings on bogies. The unloading mechanism comprises an arcuate guide and a roller, one of the two being located on the goods container and the other beside the travelling path, and both when engaged in cooper- ation causing the goods waggon to turn about its longitudinal axis. The drawback of unloading mechanisms of this kind known in prior art is that the tilting angle of the goods waggon is not large enough. As taught by the invention, the guide wraps on the under- side around the cylindrical part of the goods container , ex- tending in helical configuration from one end to the other thereof so that its initial and ultimate ends are located in the horizontal plane passing through the axis of the cylindrical part. With the guide can be engaged in interaction two rollers which have been rotatably carried on supporting means disposed on oppo- site sides of the travelling path. When the waggon is pulled to the unloading station, the first roller at the initial end of this station comes into contact with the underside of the guide forcing as the waggon proceeds forward without stopping the goods container to turn in its bogie bearings through 180° about its longitudinal axis into inverted position. Hereafter the re- turning of the waggon into its transport position takes place by means of a second roller located on the opposite side of the travelling path at a higher level and rotatably carried by a sup- porting means , which roller when coming into contact with the upper side of the guide forces the goods container to turn another 180° about its longitudinal axis.
