Both the top and bottom of each inspection chute I I3 is open and a fruit chute I I8 is directed into the top of each inspection chute II8, this latter chute being pivoted to the back wall I ll of the fruit chute II8. Consequently, any fruit position on the wheel bar. . As soon as the improperly oriented fruit have had time to roll on’ the surfaces II, the clamp bar 80 is reciprocated toward the wheel surfaces 82.

Brush 2I is ad receptacles I08 positioned below the rubbers. Justed to brush off all extra fruit so that only one fruit is in each aperture I8. The fruit is then 35 After the pitting knives 88 have been withdrawn, the clamp bar 60 again moves toward the orienta carried around the drum until it reaches a posi tion stage. , tion adjacent the output chutes 25. As the fruit It will be noted that no strippers are necessary, is discharged from the drum into output chutes, as the fruit is held during the withdrawal of the the gearing in the gear box is adjusted so that the fence bar is in upper position 46, thus holding 40 pitting knives by the clamp arms. As the clamp bar 80 moves again toward the orientation stage, the fruit at the end of the chute. Thus, I do not still grasping the pitted fruit, the clamp bar 60, by depend for timing on the fruit rolling down virtue of the design of the internal cam operat through chute 25 or on any accurate release of ing the clamp bar, stops momentarily midway be the fruit from apertures I3. Consequently, drum tween the pitting stage and the orientation stage, I2 may be continuously rotated.

As the operating rod ‘I0, how the gear box 35, the fence bar lI lowers to hori ever, traveling in this direction will not hinge, the zontal position and the fruit held in the chutes clamps are opened and the fruit drops out of the 25 drops into fence apertures 02 where it is sup clamps in a‘ position as shown by the dotted fruit ported by the sides of the apertures and by the 50 outline I80 midway between the pitting stage and upper peripheral surfaces of wheels 41. The wheels are rotated by motor 58 and the fruit is rotated by frictional contact with the wheels just the orientation stage in Fig. 5. The fruit, being released from the clamp arms, drops through fruit chute II8. Inasmuch as the inspector shaft I00 has been rotated a quarter the wheels. When, however, the stem indent of 55 turn by dogs I05 and ratchet wheels I 08 during a fruit registers with the wheel, the fruit will no this movement of bar 60 from the pitting stage longer be rotated by the wheel, as the wheel is to the discharging position, inspection chute II3 made of su?iciently small diameter that the wheel has already been set to direct the dropped fruit will fit into and either not contact the stem in into the proper output, depending upon whether dent at all or only lightly contact it.

When a carrier is used, with multiple stage orientation, I have found that quite often a fruit which has been properly oriented in prior stages is disturbed from its proper orientation in subsequent stages. Thus, the difference in the percentage of oriented fruit obtained in a single stage orlentator as compared with the ‘percentage attained in a multi-stage orlentator is not so turn stroke the stripper rods I6I_ are not actu different asv might at ?rst appear.
