FIGURE 17 is a broken sectional View of the structure illustrated in FIGURE 16 taken substantially along the line 17-17 thereof.

Referring to the drawings, and particularly to FIG- URES 1 through 4, inclusive, thereof, the side wall filler of the present invention is herein illustrated and described in an illustrative but not in a limiting sense. as installed in a railway boxcar generally indicated at 20 and comprising a oor 22, spaced side walls 24 and 26, roof structure 28 and an end wall 30. The car includes conventional doorposts 32 defining door openings closed by -doors 34. The side wall fillers of the present invention are generally indicated at 36 and in the preferred e1nbodi ment illustrated are shown as mounted on the side wall 26.

The side wall filler 36 generally comprises a panel 38 which, in the preferred embodiment illustrated, is formed of a at sheet of plywood which is movable Vas hereinafter described between a plurality of positions, in each of which the panel is disposed parallel to and is connected to the side wall 26. The inner face of the panel, that is, the face remote from the adjacent side wall 26 is `adapted to engage and support freight or merchandise. The panel is provided with a pair of spaced feet 40 mounted on the outer face thereof and extending downwardly from the lower edge of the panel and carrying a roller 42 at the bottom thereof for supporting the panel on the floor 22 for easy rolling movement between its operative positions (see FIGURE 6). The side wall filler 36 of the present invention also includes three vertically spaced anchor strips 44 which extend horizontally along the side wall 26 and, in the preferred embodiment illustrated, are welded to the Z-shaped vertically disposed structural elements 46 forming a part of the side wall 26. The panel 38 is permanently connected to the anchor strips 44 by attachment assemblies generally indicated at 48. In the preferred embodiment illustrated there are three of these attachment assemblies, all of which are identical and accordingly, only one of these `assemblies will be described in detail. Each includes leaves 50, 52 and 54. In each of these attachment assemblies 48 there is a single large Lipper leaf 5I) which extends laterally of the panel 38 substantially the full distance between `a pair of elongated vertically extending guide strips 55 of hat-shaped cross section, as best shown in FIGURE 7, which are secured to the outer face of the panel 38 in spaced relation to the vertical edges thereof. This leaf S0 is formed of sheet metal with downwardly turned tlanges 56 [sce FIG- URE 7) at its opposite sides for structural strength and each leaf 59 is pivotally connected to an anchor strip 44 by a pair of hinges 58. At the edge remote from the hinges 58 the leaf 50 is connected to the panel 38 for pivotal and sliding movement relative thereto by journal brackets 60 mounted adjacent the corners of the leaf 50. These journal portions 62 pivotally receive pins 64 carried in pin brackets 66 which are welded or otherwise suit ably secured to tying strips 68. These strips extend vertically along the outer face of the panel 38 and are slidably retained under the adjacent flanges 70 of the guide strips 55. The vertical spacing of the pin brackets 66 on the tying strips 68 corresponds to the vertical spacing of the anchor strips 44 so that the large leaves S0 are maintained in parallel relation to each other.

Each of the attachment assemblies 48 also includes a pair of extensible leaves S4 which are spaced laterally of thc panel 38. These leaves 54 are disposed to underlie the large leaf S0 inwardly of the flanges 56 at the opposite ends thereof and support the leaf 50 when it is in the horizontal position illustrated and hereinafter described. The construction of the extensible leaf 54 is best illustrated in FIGURES l0, ll and l2, in which it will be seen that the leaf 54 includes a U-shapcd wire frame 72 having a pair of legs 74 and a web portion 76 which extends through a journal portion 78 of a journal plate 80 welded or otherwise suitably secured to an anchor strip 44. The extensible leaf 54 also includes a sheet metal section 82 which has its edge `portions 84 folded partially about the legs 74 of the wire frame 72, as best illustrated in FIGURE 1l. The sheet metal section 82 also includes journal portions 86 which are folded completely about the legs 74, as best illustrated in FIGURE l2 and which engage otlset end portions 88 of the legs 74 to provide a positive stop limiting the extension of the leaf S4. The sheet metal section 82 is pivotally connected to the outer face of the panel 38 for pivotal movement about an axis fixed relative to the panel 38 by a pivot pin 90 which extends through a pair of aligned journal or loop portions 92 integrally formed on the sheet metal section 82 and disposed intermediate and aligned with journal portions 94 of the hinge leaves 96 secured to the outer face of the panel 38.

Each of the attachment assemblies 48 also includes a pair of intermediate leaves 52 which are formed of sheet metal with downwardly turned side llanges adapted to fit over the extensible leaf 54 as illustrated in FIGURE 7. Each of the intermediate leaves 52 is pivotally mounted on the large leaf 50 by a hinge 98 mounting the leaf 50 on the anchor strip 44. The intermediate leaves 52 at the edge thereof remote from the hinges 98 has a reversely turned flange portion 100 extending therealong to provide a smooth outer surface adapted to abut the outer face of the panel 38.

Referring to FIGURE 6, it will now be appreciated that with the extensible leaves 54 in their minimum length position there illustrated in full lines, the leaves S4 hold the panel 38 against movement toward the side wall 26. When the panel 38 is moved out to the position shown in broken linees and indicated at 102, the intermediate leaves 52 have dropped down to a horizontal position in which they overlie and are supported on the extensible leaves 54 and in this position the intermediate leaves 52 prevent movement of the panel 38 toward the side wall 26. In the other position indicated in broken lincs and indicated by the reference character 104, the panel 38 is at its maximum distance from the side wall 26 and the large leaves 50 have moved down to a horizontal position in which they overlie the intermediate leaves 52 and the extensible leaves 54 and are supported by the latter, and in this position these leaves S0 hold the panel 38 against movement toward the side wall 26.

The panel 38 is releasably locked in each of the three positions illustrated in FIGURE 6 by the lock mechanism 106 illustrated in FIGURES 14 through I7, inclusive. This lock mechanism 106 comprises a channel-shaped housing 108, one end of which is pivotally supported on the intermediate one of the anchor strips 44 intermediate the hinges 58, by a hinge 110. At its opposite or free end the channel-shaped housing 108 has a short portion of its flanges brought together and welded as indicated at 112 to provide a fixed stop 114 facing the hinged end of the housing 108. A latch strip 116 extends into the open free end of the channel-shaped housing 108 and has longitudinally spaced shoulder portions 118, and 122 selectively engageable with the xed stop 114 of the housing 118. The latch strip 116 is welded to a push rod 124 which is mounted in an anchor plate 126 secured to the outer face of the panel 38 so as to permit the push rod 24 to move longitudinally in the anchor plate 126 and to pivot relative thereto.

The push rod 124 has an enlarged head 128 which supports one end of a coil spring which surrounds the push rod 124 and acts between the head 128 and the adjacent edge of the anchor plate 126. It will now be seen that the spring 130, through the push rod 124, holds the latch strip 116 in the position illustrated in FIG- URE 16, but permits it to be moved by the operator upon pushing the push rod 124 upwardly, as there illustrated, or to the left as viewed in FIGURE 2, so as to move the latch strip 116 out of engagement with the stop 114. The shoulder portions 118, 120 and 122 on the latch strip 116 are so spaced that when the panel 38 is in the position illustrated in full lines in FIGURE 6, the shoulder 118 will be in engagement with the stop 114 to hold the panel against movement away from the side wall 26 and similarly, when the panel 38 is in the broken line position indicated at 102, the shoulder 120 will be in engagement with the stop 114 and when the panel is in the position indicated at 104, the shoulder 122 will be in engagement with the stop 114.

In addition to the three operative positions illustrated in FIGURE 6, the side wall filler 36 may be moved to the stored position illustrated in FIGURE S and it will be seen that in moving from the position illustrated in full lines in FIGURE 6, to the stored position of FIGURE 5, the panel 38 must be raised because the leaves 54 must pivot upwardly from the horizontal position illustrated in FIGURE 6 to a vertical position. The panel 38 is held in the stored position illustrated in FIGURE 5 by a pair of hangers 132 in the form of generally rectangularlyshaped closed wire elements, the opposite side portions 134 of which are generally S-shaped as illustrated in FIGURE 13. The hanger elements are secured to the panel 38 by brackets 136 and extend into apertures 138 provided in the panel. The brackets 136 have flange portions 140 which engage the S-shaped side portions 134 to prevent the hanger 132 from pivoting downwardly about its pivotal connection with the bracket 136 beyond the position illustrated in FIGURE 13 so that, as the panel is moved to the stored position illustrated in FIG- URE 5, the hanger 132 is disposed in the position illustrated in FIGURE 13 and adapted to be hooked over supports 142 provided on the anchor strips 44. In the preferred embodiment illustrated there are four such hanger elements 132 mounted on each panel 38 and disposed to engage supports 142 provided on the upper and intermediate anchor strips 44.

The lowermost attachment assembly 48 carries a plywood filler strip 144 extending across the bottom of the extensible leaves 54 thereof and secured thereto by screws 146 extending through apertures provided in the sheet metal section 82 of each leaf 54. As illustrated in FIG- URE 5, when the side wall filler 36 has been moved to the stored position, this strip 44 fills a portion of the space below the panel 38 and also protects the portion of the lower attachment assembly 48 which is between it and the side wall.

It will now be appreciated that the above described side wall filler may be readily moved from the stored position illustrated in FIGURE 5, to the operative position illustrated in full lines in FIGURE 6, by grasping the panel 38 by means of hand-holds 148 and 150 provided for this purpose and raising the `panel to lift the hangers 132 off of the supports 142 and swinging the panel 38 outwardly and downwardly from the side wall. When the panel reaches the full line position illustrated in FIGURE 6, the lock mechanism 106 is in the position illustrated in FIG- URE 16 and holds the panel against movement away from the side wall and the leaves 54 hold it against movement toward the side wall. The operator may move the panel to the position 102 illustrated in broken lines in FIGURE 6 bv engaging the push rod head 128 through the -panel aperture 152 and moving the latch strip 116 to move the shoulder 118 out of engagement with the stop 114, permitting him to pull the panel away from the wall while it is supported on the rollers 42. When the panel reaches the position 102 the intermediate leaves `52 have dropped into horizontal position and the shoulder 120 has moved into engagement with the stop 114 by again moving the push rod 124. The operator may release the lock mechanism 106 and move the panel out to the position 104 in which the large leaves 50 have dropped into horizontal position and the shoulder 122 has moved into engagement with the stop 114. To insure that the leaves 50 are fully down, the operator may place his foot on the end thereof adjacent the panel to press the lowermost leaf 50 fully down and through the tying strips 68 and the leaves 50 of the intermediate and upper attachment assemblies will also be pulled into their final horizontal position.

While only one specific embodiment of the present invention has been illustrated and described in detail herein, it will be readily appreciated by those skilled in the art that numerous modifications and changes may be made without departing from the spirit of the present invention.
