 <EMI ID = 2.1>

  
In a particular type of sorting machine of this kind, the change of the intervals between the bars is caused by eccentric cam guides on which the ends of the bars come to rest, the cams placed

  
on either side of the drum causing radial displacement

  
 <EMI ID = 3.1>

  
re sorter "

  
In machines of this type already existing ... all the bars are cylindrical and none of the heavy parts can thus impart to the treated vegetables $ impulses tending to bring them into the longitudinal position most favorable to their passage between the bars.

  
 <EMI ID = 4.1>

  
to adapt them to each of said calibers.

  
The object of the present invention is to provide, to said machines, improvements overcoming the inoon-

applied against the last one and having a cutout in silk teeth, while the pebbles can come into

Another improvement consists of the fact that the ring cut into sawtooths can undergo displacements around its axis capable of varying the point of tangency.

  
 <EMI ID = 8.1>

  
silk teeth, thus varying the distance of the mobile barras with respect to the center of the drum, the intervals between the fixed bars and the mobile bars undergo proportional variations.

  
The floss toothed teeth of the ring attached to

the fixed bars can be made

The rollers 15 of the movable bars can enter

made of plastic or other material, passes through the grooves of all the pulleys 14 of the same flange and constantly tends to bring all the movable bars towards the center of the drum.

  
A ring 18 (fig. 5) is held against the face

or bolts 20 (fig.l) 'passing through a hole in the flange and curved openings 21 made in the yoke. This mounting method or any other similar, allows the ring to be turned slightly relative to the flange and consequently to modify the position of the point of tangency between the pulley.
14 corresponding and the inclined side of one of the saw teeth of the ring, relative to the counter of the drum. It follows that the position of the movable bars relative to the fixed bars can by this means be adjusted at will, which allows the screening interval to be brought to the desired size.

  
As shown in figure 6, the walls of the buckets

The rollers 15 'of the mobile bars 26 can
