Ashlock, Jr., Oakland, Calif. Appliéation February 2,11, 1945, serial No. 579,141 >12, Claims. (Cl. 1538-33) 1 2 This invention relates to improvements in de vices for receiving an article in any position and for orienting the article into adesired position. A typical example of this is the so-called straight ening operation performed upon cherries and like fruits, the cherries being deposited upon the de vice in haphazard positions of alignment, the de vice operating upon the cherries to place them in a desired position, usually one wherein the stem indent in the cherry and the longitudinal 10 pit axis are in alignment with a vertical axis. ‘ Orientation or straightening of such articles is generally practiced because the articles are sub ject to a subsequent operation wherein the stone 0r pit present is removed or lthe article is other wise processed. With the article in a predeter . invention to provide an improved orienting de vice. v , ~ A further object of the present invention is to provide an orienting device in which the article is positively rotated until it is oriented, the article thereafter being maintained in its oriented posi tion. A - The invention includes other objects and fea tures of advantage, some of which, together with the foregoing, will appear hereinafter wherein the present preferred form of orienting device is disclosed.

VReferring to Figure - isY . To provide a support for the orienting members a plate 5I is mounted upon each of the fruit car riers I?. As is illustrated in Figure 6, each car rier is secured at each end to chain I4 by a screw 52. Each screw extends into a rod 63 which'posi tions the carrier and acts as a spacer and sup port for plate ßI, the threaded end 64 of the rod being passed through the plate 6I, nuts 66 being placed thereon to secure the plate in position. 2,406,31 1 5 6 Thus, each plate 6| extends across the machine beneath each of the carriers in a fixed spaced relation.` A threaded barrel 1| is screwed 4into each plate below and in alignment with each aperture 23 to provide a support for a shaft 12 ci which is passed through the barrel. A spring 13 ` is positioned between shoulder 14 on the shaft 12 and a drive pulley or wheel 16 positioned on the end of shaft 12 and secured in place by screw 11 andwasher 18.
