Abstract

The present invention provides that a spinner disc (40) of the type which is carrier by a vehicle and is for spreading salt on roads to keep them free of snow and ice, is designed to direct the salt, as it is propelled from the spinner disc, in a downwards direction so that it will not impact on the side body work of passing vehicles. To achieve this the vanes (52) on the spinner disc (40) have along their upper edges (54) which incline in a downwards manner in a direction from the centre to the periphery of the dics, turned over portions which are also so inclined. These turned over portions (54) catch the material (M) which is centrifugally propelled by the vanes (52) and direct it in a downwards direction as it leaves the spinner disc (40). Additionally, the vanes (52) at their inner edges project through an aperture (41) in the centre of the disc (40) and form fan blades (43) by which air is drawn onto the upper surface of the disc (40) to assist in propelling the material (M) from the disc (40). <IMAGE>
