JZ w 74/ F U 1a 7 United States Patent M 3,344,750 FREIGHT BRACING APPARATUS John J. Kostrewa, Detroit, Mich., assignor to Evans Products Company, a corporation of Delaware Continuation of application Ser. No. 344,124, Feb. 11, 1964. This application Jan. 6, 1967, Ser. No. 622,376 18 Claims. (Cl. 105-369) The present invention relates to freight bracing apparatus of the type adapted for use in freight receiving chambers for effecting a desired reduction in one dimension of the chamber to eliminate excessive clearance between the freight and the walls of the chamber.

This application is a continuation of my copending patent application of the same title, Ser. No. 344,124, filed Feb. 11, 1964, and assigned to the assignee of this application.

One common use of such equipment is in railway boxcars where it may be installed along one or both sides of the car and is commonly referred to as side wall fillers, or just side fillers. For purposes of illustration, but not by way of limitation, the improved freight bracing apparatus of the present invention will be illustrated and described herein as installed and used in a boxcar. It will be appreciated that side fillers are desirable where the nature of the load is such that it cannot be made to fill the full width of the car, but is such that a side filler can adequately engage it to support it against lateral shifting. This is frequently the case with freight in cartons, boxes or crates and especially so with palletized loads.

It is an object of the present invention to provide improved freight bracing apparatus of the above mentioned type which is simple in design, rugged and durable in construction reliable and eflicient in operation, readily adjustable between a stowed position and a plurality of operative positions, which occupies a minimum of space in the stowed position, which has a wide range of operative positions, and which is supported in spaced position above the floor and is easily moved between all positions.

Other and more detailed objects of the present invention will be appreciated by those skilled in the art from a consideration of the following description, the appended claims and the accompanying drawings, throughout the several views of which like reference characters designate like parts and wherein: 7

Referring to the drawings, FIGURES 1 and 2 show a fragmentary portion of a railway boxcar generally indicated at 20 and including a floor 22, an end wall 24 and a side wall structure 26 which includes vertically extending Z-shaped structural posts 28, These figures show a plurality of the applicants improved side fillers generally indicated at 30 which, it will be appreciated, are shown in a variety of positions of adjustment for purposes of illustrating different operative positions which the side filler may occupy, as well as illustrating its stowed position, the right-hand side filler 30, as viewed in FIG- URES l and 2, being in its stowed position and the other side fillers 30 being in four different operative positions. In actual use it is unlikely that the side fillers would occupy the positions illustrated, in any given loading of the car. It will be appreciated, of course, that in its stowed position the side filler is also adapted to be engaged by and to support freight against lateral movement.

Each side filler 30 generally comprises a panel 32 formed of plywood or other suitable material which is connected to and supported on the wall structure 26 by frame means generally indicated at 34, see FIGURE 3. This frame means supports the panel 32 on the wall structure posts 28 for movement at right angles to the wall structure 26 between its stowed position and a plurality of operative positions, several of which are illustrated in FIGURES l and 2 and includes means for holding the panel in each of its positions.

The panel 32 is provided with handgrip recesses 36 at the opposite sides thereof to facilitate gripping of the panel during movement thereof between its various positions. On the back of the panel, that is, the side of the panel adjacent the wall structure, and extending vertically therealong in spaced relation to the opposite edges thereof, are a pair of angle frame elements 38 which are secured to the panel 32 by a plurality of bolts 40. Mounted on the posts 28 of the wall structure 26 are four vertically spaced horizontal wall frame strips 42, 44, 46 and 48, best shown in FIGURES 4 and 5. These strips are interconnected by vertically extending wall frame strips 50 and 52 and the wall frame formed by the strips 42 through 52, inclusive, is welded in position on the posts 28. In the preferred embodiment illustrated the horizontal wall frame strips 42, 44, 46 and 48 of each side filler 30 have an offset postion 49 for overlapping the adjacent end of the corresponding strip of an adjacent side filler and facilitating connection thereto as by welding.

Extending between the angles 38 and the wall frame formed by the strips 42 through 52, inclusive, and generally indicated at 54 (see FIGURE 4) in the preferred embodiment illustrated, are a pair of scissor-type interconnecting frame assemblies generally indicated at 56 and 58, as best seen in FIGURES 3 and 5. These upper and lower frame assemblies 56 and Y58 are substantially identical, except that the upper frame assembly 56 carries the latch structure as hereinafter described. Each of the frame assemblies 56 and 58 includes an outer U-shaped frame section 60 and an inner U-shaped frame section 62. The frame section 62 has spaced parallel legs 64 which are disposed between the spaced parallel legs 66 of the outer frame section. Adjacent their midpoints, the

legs 64 and 66 of the frame sections 60 and 62 are pivotally connected by a rod 68 so that the frame sections 60 and 62 and the interconnecting rod 68 form an assembly very similar to the well-known campstool without the canvas seat. The legs 64 and 66 are channel-shaped and oppositely facing, as shown in FIGURE 6, with their web portions adjacent one another. The opposite ends of the rod 68 extend through flanged ferrules, the heads of which are shown at 126 in FIGURE 4 and serve as bearing surfaces maintaining the legs 64 and 66 in spaced relation. The ends of the rod 68 are held against withdrawal from these ferrules by any suitable means, such as the washer 128 and cotter pin 130 shown in the lower right-hand portion of FIGURE 4. The free ends of the legs 66 of the frame section 60, that is, the ends corresponding to the feet of the campstool frame, are connected to the wall frame 54 adjacent the top and bottom thereof as illustrated in FIGURE 5 by hinges 70, one leaf of each hinge at the upper end of the frame 54 being welded to the frame strip 42 and the corresponding leaf of each hinge at the lower end of the frame 54 being welded to the frame strip 48. The other leaves of the hinges 70 are welded to the legs 66. The free ends of the legs 64 of the frame section 62 are slidably mounted in tracks 72 which are vertically disposed and welded to the wall frame strips 44 and 46 as shown in FIG- URE 5, the tracks 72 of the upper frame assembly 56 being welded to the frame strip 44 and the tracks 72 of the lower frame assembly 58 being Welded to the frame strip 46. As best shown in FIGURE 6, these tracks 72 are formed of sheet metal and rectangular in cross section and provided with an opening 74 through which the end portion of the leg 64 extends. Welded to the end of the leg 64 and disposed within the track 72 is a transverse pin 76 adapted to slide along the track 72 and co-operate with the latter to prevent movement of the end of the leg 64 at right angles to the wall structure 26. At the opposite ends of the legs 64 the inner frame section 62 is completed by a bar 78 which extends at right angles to and is welded to the legs 64 and extends substantially beyond these legs 64 to provide end portions 80 which are 'pivotally mounted in bearing strips 82 welded on the angles 38. The bar 78 is held against longitudinal movement by tabs 84 struck upwardly from the angles 38 as best illustrated in FIGURES 4, 6 and 9.

In the frame section 60 the ends of the legs 66 adjacent the panel 32 are interconnected by a tube 86 welded to and extending beyond the legs 66. This tube 86 at its opposite ends carries pins 88 which are selectively received in apertures90 in latch strips generally indicated at 92 which are movably mounted on the angles 38 at the back of the panel 32. This latch strip 92 is formed of sheet metal and is generally Z-shaped in cross section as best illustrated in FIGURE 6. One flange 93 of the latch strip 92 extends longitudinally of the angle 38 and is mounted thereon for sliding movement transversely of the angle 38 and parallel to the panel 32 by guide plates 94 and 96 welded to the angles 38. The guide plate 96 is cut out as indicated at 98 to provide a recess covered by the guide plate 94 which receives the end portion of the flange 93 of the latch strip 92. The web portion 100 of the latch strip 92 extends at right angles to the panel 32 and has the above-mentioned apertures 90 formed therein, which apertures 90 receive the pins 88 when the latch strip 92 is in the latched position illustrated in full lines in FIGURE 6. The latch strip 92 may be moved by means hereinafter described, from the latched position to the unlatched position illustrated in broken lines in FIG- URE 6, in which it will be seen that the portion 100 of the latch strip has been moved to the left of the ends of the pins 88, thus disengaging the latch strip from the pins 88. The second flange 102 of the Z-shaped latch strip 92 extends at right angles to the web portion 100 in the opposite direction from the flange 93 and in spaced parallel relation to the panel 32. It will be seen in FIGURE .6

tube 86 from moving in a direction at right angles to t and away from the panel 32. It will also be appreciated that when the latch strip 92 is in the retracted position illustrated in broken lines, it co-operates with the angle 38 to guide the pins 88 during, and permit movement of the same longitudinally of the panel 32 and the angle 38. Such movement, of course, occurs after movement of the latch strip to its unlatched position and during movement of the panel 32 at right angles to the Wall structure 26 for moving the panel 32 between its various positions. In each of the operative positions of the panel 32 each of the pins 88 is aligned with one of the apertures in the latch strips 92.

Movement of the latch strips from the latched position illustrated in full lines in FIGURE 6 to the unlatched or retracted position there illustrated in broken lines is effected by a handle 104 (see FIGURES 4 and 11), which is pivotally mounted on the panel 32 by a mounting and 112 which carry the latch strips 92 welded to the outer ends of the plates and which have overlapping corner portions, each provided with an elongated slot 114 through which extends the pin 108 upon which the handle 104 is mounted. The plates 110 and 112 are pinned to the handle 104 at opposite sides of the pin 108 by pins 116 and 118, respectively. It will now be appreciated that as the handle 104 is moved in a clockwise direction from the position illustrated in FIGURE 4, it will act through the plates 110 and 112 to spread the latch strips 92 further apart, moving them from their latched position illustrated in FIGURE 6 in full lines, to the unlatched position there illustrated in broken lines. Return of the latch strips 92 to their latched position is effected by a spring 120 which is connected between the plates 110 and 112 as illustrated in FIGURE 4 and which, upon release of the handle 104, will return the latch strips 92 to their latched positions when the pins 88 are substantially aligned with apertures 90 in the latch strips 92. As best shown in FIGURE 6, the pins 88 have tapered ends facilitating engagement of the pins 88 in the latch strip apertures 90 and the accompanying return of the latch strips 92 to their latched position.

Movement of the pins 88 beyond the ends of the latch strips 92 during movement of the panel 32 away from the wall structure 26 while the latch strips 92 are in the unlatched positions, is prevented by stops 122 formed by turning the opposite end portions of the flange 102 through an angle of ninety degrees to a position best illustrated in FIGURE 6 so that they extend toward the panel 32. Access to the handle 104 from the front of the panel 32 is provided by a rectangular handle opening 124 best shown in FIGURES 2 and 4.

Referring now to FIGURES 4, 5, 11 and 12, the side filler 30 is held in the stowed position which, as indicated above, is the position of the right-hand side filler 30 illustrated in FIGURES 1 and 2 and the position shown in 7 FIGURE 11, by a latch generally indicated at 132 which comprises a latch cylinder 134 mounted centrally of the horizontal frame strip 44 and carrying a latch bolt 136 which is urged downwardly by a spring 138 housed within the cylinder 134, the upper end of the spring engaging a washer 140 held in the upper end of the cylinder 134 and the lower end bearing against detents 142 formed on the latch bolt 136. In the preferred embodiment illustrated, the latch bolt 136 extends through an aperture 144 provided in a horizontal flange 145 formed on the central portion of the frame strip 44 and extending toward the panel 32. The upper end of the latch bolt 136 is turned toward the panel 32 to provide a handle portion 146 which is accessible through a latch handle opening 148 provided in the panel 32. Turning of the latch bolt 136 in the cylinder 134, such as would interfere with access of the handle portion 146 through the opening 148, is prevented by a short rod section 150 which is Welded to the latch bolt 136. When the side filler is in its stowed position the lower end of the latch bolt 136 engages behind a keeper plate 152 which is Welded on the tube 86 as shown in FIGURE 11. When it is desired to move the side filler from the stowed position, the latch handle 146 is engaged to raise the bolt 136 out of engagement with the keeper 152 permitting the panel 32 to be moved away from the wall until the pins 82 become aligned with certain of the holes 90 in the latch strips 92.

It is believed that it is clear from the foregoing description of the illustrated structure that the latch strips 92 may be moved to their retracted or unlatched position by the handle 104, after which the'panel 32 may be moved to any selected one of its operative positions. The particular one of the operative positions in which the side filler is disposed is indicated by the position of the tube 86 which may be seen through a position indicator opening 154 provided in the panel 32 and the distance of the panel 32 from the side wall structure posts 28 may be directly read from indicia provided on the panel 32 adjacent the indicator opening 154. In one preferred embodiment the panel 32 is movable between five operative positions in which the freight engaging face of the panel 32 is spaced approximately five, eight, ten, twelve and fourteen inches, respectively, from the normal car side wall lining position, i.e., the position of the freight engaging face of the inner wall lining which would be on the posts 28 had it not been replaced by the side fillers 30.

It will be noted as best illustrated in FIGURE 5, that the portions of the legs 64 and 66 of the frame assemblies 56 and 58 at opposite sides of the pivot rods 68, are slightly different in length, the portions between the pivot rods 68 and the panel 32 being slightly longer than portions between the pivot rods 68 and the wall. This facilitates collapsing of the side filler into a minimum space in its stowed position.

It will also be noted that the above described side filler is supported on the side Wall structure and positioned in spaced relation above the floor 22. This facilitates easy movement of the panel 32 between its various positions. To prevent anything from projecting into or being caught under the lower edge of the panel 32 when it is in the stowed position, a filler strip 156 formed of Wood or other suitable material, extends along the floor 22 in engagement with the posts 28 and is of a height from the floor to substantially fill this space. Also, to prevent anything from projecting into or being caught in the space behind the panel 32 of the side filler 30, which is adjacent the freight car door opening indicated at 158, when the side filler is in its stowed position, a vertical strip 160 is provided which may be formed of plywood or other suitable material and has one vertical edge fastened to .the post at the doorway opening and has its other vertical edge disposed in close proximity to the edge of the panel 32 of the adjacent side filler when the latter is in its stowed position.

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