Abstract
A suspension system is presented for a distribution chute of a device for uniformly spreading powdery materials over a circular surface. The distribution chute is suspended in a pivoting manner from a cage in such a way that the angle of tilt of the chute in relation to the vertical axis is adjustable. This cage is suspended from a peripheral annular ring having a vertical axis. The ring is vertically supported and laterally guided by wheels circumferentially spaced apart by an angle of 120.degree.. These wheels are mounted via bearings on a frame supporting the cage. An endless chain engages in a peripheral annular sprocket integrally connected to the cage in order to transmit to the latter a rotary motion about its vertical axis. A variant embodiment is presented with six smooth wheels, three of which have horizontal axes and three of which have vertical axes.
