I claim:
1. For use on a rack structure having inclined tray supporting elements with a vertical series of notches providing hooks for engaging and supporting the trays. a tray structure formed of sheet ness very materially increases the strength of the tray. the arrangement is such that the tray is not held out away from the rack 4 but, as shown in Figure 2, the lowerrear-comer of the tray bears against the front edge of the rack 4 so that any thrust due to the'loading of the tray is resistled by the back wall being engaged against the rac To additionally strengthen the rear top edge of the tray along the region of the pockets, a longitudinally extending angle bar I4 is welded into the upper part of the tray with the vertical leg ofthe angle flush against and extending along the back wall 9 and with the horizontal web of the angle extending forwardly. A relatively light angle ll thus welded in place renders the back of the tray structure quite rigid and prevents deformation of thepockets.
As shown in Figure 5, the forward edge ofthe bottom 1 is also formed of metal of double thickness flattened upon itself and formed down into a depending lip IS. The double thickness of metal forming this lip portion-of the tray is further reinforced by a longitudinally extending angle bar It welded into place with the vertical web of the angle backing up the lip l5 and with the horizontal web of the angle bracing the forward edge of the bottom.
The tray as thus constructed is'extremely rigid and capable of supporting heavy loads even though unequally placed upon the tray and the tray is highly resistant to abusive treatment and rough handling. In some cases the trays may function more in the nature of bins, in which case the forward edge of thetray is made as shown in Figure 6, while the rear wall is of the construction previously described. As shown in Figure 6, the metal forming the bottom I. is carried forward to provide an upwardly extending metal with a bottom, end walls. and a back wall. the metal at the top of the back wall being folded over and flattened upon itself to provide atop portion of double thickness. the said portion of double thickness being outwardly folded upon itself and flattened down at each end and at the middle of the tray and being secured to the back wall of the tray where it is so flattened down, the portions intermediate the flattened down portions sloping downwardly and outwardly away from the back wall of the tray to provide elongated inverted hook engaging pockets.

To facilitate the handling of the tray there-is a handle assembly designatedgenerally as I! on each end wall of the tray. This handle comprises a metal plate 20 having an outwardly bent ridge 2| "intermediate its upper and lower edges,
