1292879 Spreading implement C VAN DER LELY NV 13 Jan 1970 [17 Jan 1969] 1710/70 Heading A1D A spreading implement comprises a container having two portions one of which can be arranged substantially wholly inside the other and/or is collapsible, and has a mechanism for controlling discharge of material from the container to at least one spreading member. In Fig. 1 the container I comprises two sections 2, 3, having flanges 5, 6, joined by bolts 7, and so dimensioned that, when separated and with frame parts dismantled, the lower section 3 will fit inside the upper section 2 for transport and storage purposes. In Fig. 7 the upper section 96 is made of a flexible material, tensioned between upper and lower rings 105, 106, by means of rods 113, 114, joined and length-adjustable by turnbuckles 123, so that with the rods removed the flexible wall collapses. The bottom section 25 of the hopper (Fig. 4) has an annular aperture 58, and the adjacent plates 61, 62, have apertures 63, 64, 65, 66. Disc 61 can rotate relative to disc 62, from a position in which face 85 abuts stop 88 when the holes in the discs are completely out of register and no material can flow from the container, to a 'position in which face 86 abuts a stop 76 which is adjustable in an annular slot 75 in plate 62, and material can flow from the container, the degree, of register of holes 63, 65, and 64, 66, depending on the position of stop 76. The plate 62 can be angular-position-adjusted relative to the con tainer by selectively engaging a spring loaded pin 72 in one of a series of holes 74, in order .to vary the direction of material discharge from the spreading member, relative to the normal direction of movement of the implement.
