Abstract: 783,911. Sorting solid materials. HERBORT W., [trading as MASCHINENFABRlK A. HERBORTI]. May 12, 1953, No. 13797/55. Class 117 In apparatus for sorting cucumbers and other articles according to their thickness and length, the articles are fed by a conveyer 31. Fig. 1, to a frame 2 comprising parallel, inverted V-shaped ribs 1 providing between them slots 6 which broaden gradually from the receiving end. Endless chains 7, Fig. 3. run below the frame and carry upwardly extending prongs 8 which push the articles along the slots until they fall through on to guides 11 and on to an appropriate one of a series of transverse conveyers 10 within a channel 9. A driven brush roller 12 with its bristles arranged in helical lines is mounted above each channel, and each conveyer 10 feeds the articles in their axial directions to an associated endless ribbed conveyer 13 for sorting according to length. Each conveyer 13 is parallel to the frame 2 and comprises a number of transverse ribs which move the articles transversely of their length over a base member 14, Figs. 5 and 7. The upper run of each conveyer 10 crosses its associated ribbed conveyer and a baffle plate 16 directs the articles into the path of a ribbed conveyer. Each base member 14 has a slot 21 therethrough, Fig. 5, which increases in width in the conveying direction, and the articles are moved over the slot by the ribs until they fall through it and into the appropriate one of a series  of collectors 15. The slot wall 26, Fig. 9, and hence the slot width is adjustable, and for this purpose threaded wall supporting rods 27 are adjustably held in position by nuts 28. Driving rollers 24, Fig. 5, in the floor of each base member 14 urge one end of each article towards an abutment 23, and a transverse belt 20 immediately below the ribbed conveyer finally urges that end against the abutment before the articles are fed over the slot. A driven roller 30, Fig. 9, adjacent the adjustable wall of the slot also urges the articles against the abutment.
