My inventionrelates-to the handling of articles such as cans; and more particularly to means for inverting a tray vofcans to facilitate removal of the tray.

In canneries Where cans are handled in batches,r the cans come from' the cooker ,ein trays. The problem is then to remove the cans from vthe tray without denting o1; otherwise-damaging the canslpreparatoryV to feeding-:the cans to the labeler.- -It is among the objects of my invention to provide a mechanism for inverting a tray full of v cans sothat the tray may beremovedby simply f lifting it oi the batch of cans.-

Another object is to provide zin-inverting device of the character described which operates in conl5 junction with means for moving the inverted cans from the device, whereby the tray may be lifted from the cans as the latter travel along a path t0- ward a discharge mechanism.

The invention possessesother objects and fea-w turesof-advantage some of which, with the fore- I going, will be set forth in the following description-of my invention. VIt is to be understood that I do not li-mit myself to this disclosure of species. of my invention', as Imay adoptvariant embodiments'thereofwithin the scope of the claims.

VThe batch of inverted cans is thus started in their forward;A

movement through the system as soon asthe platform is brought down into its extended position.. It is unnecessary that all of bed rollers 2| on the platform be positively driven, because the tray still embraces the batch at this time and all is driven forwardly as a unit.

End pulleys

29 and 3| for the drive belt are preferably journaled in brackets 32 suitably mounted for vertical adjustment .on the main main frame. i

As the batch of inverted cans is advanced along the bed of the apparatus, the overlying tray is removed, preferably by operators standing on opposite sides of the machine. At this time all of the cans are resting on the driven bed rollers, so that upon removal of the tray the cans continue to advance as a group.

In my preferred system the cansV are discharged singly by means ofla centrifugal feeder comprising a disk 4I disposed in the plane of the machine bed at the discharge end of the apparatus. The cans are converged toward Vthe' disk by guide plates 42 extending angularly across bed rollersvv 23 and terminating at the mouth of a circular guide plate 43 which lies about the periphery of disk 4 I. Plates 42 are suspended from suitable cross members 44 on the main frame, and are hinged to arcuate sections 46 adjustably of the opening.

Disk 4l is rotated clockwise as viewed in Fig-V moved outwardly against circular plate 43 by theV action ofVV centrifugal force, and are advanced in single file toward discharge chute 156. This chute is preferably twisted through 90 as illustrated in Figures 2 and 4, so that the cans roll out on their sides inposition to be carried along by lany suitable conveyor to the labeler.
