The opposite the adjacent ends of the panels in the group end of the container may be closed by a similar and thereby securely locate the several panels structure preferably xedly secured to the adjathrough their contact one with another. cent vertical posts Iii-l0.

The roof decks I9, as seen in Figure 1, are stamped metal panels which are curved both longitudinally and transversely. Along opposite side edges a molding bead 20 is formed to constitute in cooperation with the gutter piece 20a welded thereto, a drain channel or drip molding when the panel is assembled as an automobile body top. In the forward portion of its length the bead 20 carries an angular` offset comprising a downturned portion 2l and an inturned flange 22. When placed in a vertical position the lower edge of the oiTset is utilized for the suspension of the panel.

'I'his is shown best in Figure 3 where the lower edge of the offset rests upon one end of a pivoted hanger 23 resting upon the bottom flange of the angle rail I2. 'Ihe end which seats the panel offset has an upwardly open fork constituted by a pair of tines 24 and 25 bent away from each other toward the top so as to provide an upwardly opening flaring entrance mouth to receive the portion 2| of the offset. In addition the side face 2S of the tine 24 which engages with the inturned ange 22 of the oifset tapers upwardly or recedes in a direction opposite to a correspondingly inclined face 21 on the tine 25 and which engages the inturned portion of the bead 2D. The surfaces 26 and 21, therefore, provide cooperating cam faces which in conjunction with the flaring entrance mouth of the fork facilitates easy insertion of the offset and its downward movement to final seating position on the hanger 23. A pair of such hangers, one at each side of the container, serve to support each roof panel individually in the container. The engagement of the roof panels intermediate of their length with the suspension hangers effects a distribution of the load in the sense that the lower half of the panel is suspended in tension and the upper half supported in compression and this avoids the distortion and buckling ordinarily occurring when the panels are rested on their longitudinal or transverse edges.

Inasmuch as these hangers 23 project inwardly in the path of the panel during loading and unloading the pivotal mounting enables them to be swung outwardly out of interference at such times when they are not in use. For this purpose the end of the hanger opposite the fork is welded to a pivot pin 28 mounted in the adjacent upright ilanges of a series of U-shaped stampings 29 carried by the base flange of the angle I2. In order to avoid damage to the panels during loading by their engagement with the hard edge of the base flange of the angle I2 a wooden rub rail 30 is preferably bolted to the flange and projected inwardly a slight distance beyond the edge. A similar buffer is carried by the angle rail II.

To prevent displacement of the panels during transit they are clamped against one another in groups. It is proposed after say seven panels are loaded, that they be clamped together and then additional groups of seven are loaded and clamped together in succession. The clamping mechanism is carried on each side of the container by the upper rails I3 and may consist of an over center leverage device as shown in detail in Figures 4, 8 and 9. Engagement with the roof panel is through the drip channel 23a by a hook 3l connected by a link 32 with the hand lever 33. The hand lever is pivoted to a block 34 and in the clamped position of the parts, as shown in Figure 4, the opposite ends of the link 32 have their pivot axes arranged on a line belowy the axis of the swinging lever 34 so that an overcenter relation is established which resists accidental displacement. In addition a latch 35 pivoted to a bracket 36 is positioned in the path of the hand lever. Ihe pivot mounting for the latch 35 is off-center and toward one side so that normally it hangs downwardly at an angle to the vertical. It is pushed back by its engagement with the descending lever until it is cleared when it returns to locking relation and requires pushing back by hand before the lever can be released.

To guide the hook 3I on a straight line during its movement to and from clamped position it has welded thereon an L-shaped member 3l which embraces the inner edge of the horizontal flange on the angle I3. This member also locates the hook 3| in the path of the drip molding 20a and consequently to facilitate passage of the roof panels in and out of the container it is desirable that the clamping mechanism be shiftable laterally beyond the ange edge and held within the vertical limits of the angle member I3. Accordingly the pivot connections between the parts are loose or sloppy and this enables the member 35 to be disengaged with the edge of the angle I3 and placed above the inturned flange. To hold the parts outwardly the hand lever 33 is thrown behind an angle clip 38 which through its frictional engagement prevents accidental displacement of the handle during return shipment of the empty container and during the loading and unloading of the panels.

In order that the container may be universal for use with panels of different dimensions, it is proposed that the rails II and I2 be mounted adjustably for height and width. Accordingly, these rails at each side form a subassembly unit and are joined at their ends to the vertically disposed angle irons 39 and are braced by diagonal struts 4U. The two subassemblies along opposite sides can then be fastened to the corner posts I0 at the desired vertical and transverse position by a series of bolts and nuts as at 4I in Figure l1, passing through alined openings in the inturned leg of each angle 39 and its adjacent post I0. In the illustrated embodiment, the post contains three groups of four openings, respectively offset vertically and transversely for selective alignment with corresponding holes in the angle iron. The outer and lowermost group is for fastening the side frame to accommodate sedan roofs, the intermediate group positions the frame as shown for coach roofs, and the inner and uppermost group locates the frame for coup roof, panels, the variation in height being determined by the interruption or termination of the offset side flanges 2I-22 in the individual types of roof panels.
