While it will be readily appreciated by those skilled in the art, that the improvements of the present invention may be readily incorporated in freight bracing apparatus of widely differing types and sizes having numerous applications, the improvements of the present invention are herein illustrated and described as embodied in apparatus for supporting and bracing a wide variety of general merchandise in railroad boxcars.

Referring to the drawings, and more particularly to freight bracing apparatus illustrated in FIGURES 1 through 13 thereof, the freight bracing apparatus of the present invention is there illustrated as mounted in a railway boxcar having opposite side walls I0 and 12 and end walls 14. The side walls It? and 12 have secured thereto a plurality of belt rails 16. In the preferred embodiment illustrated these belt rails 16 are disposed in vertically spaced parallel relation and are disposed horizontally. The belt rails I6 on the opposite side walls I@ and 12 are disposed at corresponding levels so that crossbars supported thereon will be disposed horizontally.

These belt rails support a plurality of crossbars generally indicated at 1S extending transversely of the boxcar between the side walls llfl and I2 and which are supported on and secured to the belt rails f6 by

end fittings

20 and 22. In accordance with previously known practice, the end fitting 2t? is secured to the crossbar 18 in fixed relation thereto and the end fitting 22 is telescopically mounted for movement longitudinally of the crossbar I3. In the particular use illustrated in FIGURE 1, the crossbars 13 are employed to support a transversely extending bulkhead or gate 24.

The belt rails 16 are of a cross section best illustrated in FIGURES 3 and 4 and may be suitably formed in a roliing process. These belt rails include a channel-shaped attaching portion 26 having a vertically extending web portion 28 adapted to engage and be secured to the vertically extending frame members Si) of the boxcar. The upper leg 32 of the channel portion 26 terminates in an upwardly turned supporting iiange 34 which extends parallel to the side wali of the car spaced inwardly therefrom. The upper edge 36 of the supporting flange 34 provides a horizontal surface extending longitudinally of the freight car which supports the end fittings Ztl and 22 for sliding movement therealong, as hereinafter described. The lower leg 33 of the belt rail channel portion 26 is downwardly and outwardly turned to provide a vertically extending portion itl which, in the preferred embodiment illustrated,

is vertically aligned `with the supporting flange 3d and to provide a leg portion 122 for engaging the wall l@ to support the lower end of the portion di?. The belt rail i6 may be secured to the side wall in any suitable manner. if desired, the belt rail may be removably secured by bolts or screws extending through the web ZS of the channel portion 26.

ln the preferred embodiment the belt rails are secured in place by welding, welds i4 and i6 being indicated, respectively, at the upper side of the channel portion 26 and at the bottom side of the leg 42. rthe number of belt rails 16 spaced vertically of the boxcar side walls may be varied as desired, depending upon the intended use of the boxcar and where the vertical spacing between the belt rails is sufiicient, buffer boards 4S may be secured to the side walls between the belt rails, or, where the belt rails are closely spaced, the buffer boards therebetween may be eliminated.

It will be appreciated that the supporting tiange 31tand the belt rail portions #tti define substantially fiat surfaces facing the interior of the car which substantially eliminate the likelihood of damage to the freight by engagement with the belt rail. The vertically extending portion Lttl of each belt rail i6 is provided with a plurality of longi tudinally spaced apertures S extending therethrough for receiving co-operating portions of end fittings 2G and 22 as hereinafter described for locking the end fittings in desired positions of adjustment longitudinally of the belt rail.

The crossbar i8, except for the end fittings, may be of any suitable construction and in the preferred embodiment illustrated is of the genaral construction illustrated and described in my prior United States Patent No. 2,887,963 and includes a generally Z-shaped reinforcing metal member 52 (best illustrated in FIGURE 5) and a pair of wood members 54 and 56 secured to opposite sides thereof by through bolts Sti. The end fittings Ztl and 22 differ from each other only in their structure for connection to the body of the crossbar 18. The iixed end fitting 2t) may be connected to the body of the bar 1S in any suitable way and in the preferred embodiment illustrated, has spaced attaching legs 69 and 62 which are similar in construction to and are secured to the Z-shaped reinforcing member 52 of the crossbar 18 in the same manner as are the legs of the fixed end fitting illustrated and described in my above mentioned Patent No. 2,887,- 963. In the present construction each of the legs 6G and 62 is welded to the member `52. The end fitting 22, in the preferred embodiment illustrated, has a shank portion 64 which is telescopically connected to one end of the crossbar 18 in the same manner and by the same construction as the telescoping end fitting illustrated and described in United States Patent No. 2,837,039 issued to the assignee of the present application on an invention of G. M. Schueder.

Referring now to the portions of the end fittings Ztl and 22 which, as viewed in FlGURE 3, are disposed externally of the body portion of the crossbar 18, it will be seen that the end fittings are of the same construction and accordingly, like reference characters are employed for each. This outer portion of the yend fittings 2li and 22 comprises a generally U-shaped body 66 which is integrally connected with the attaching legs 6l! and 62 in the case of the end fitting and which is integrally formed with the shank 64 in the case of the end fitting 22. An end plate 68 is welded across the outer end of the U-shaped body 66 and cooperates therewith to define a vertically extending opening 7th in which is mounted the latch 72. The U-shaped body portion 66 has two spaced arms 74 which extend generally longitudinally of the crossbar i8 in spaced parallel relation, as best illustrated in FGURE 2. The end plate 68 extends across the outer ends of the arms 7d and is welded thereto along the line indicated at 76 in FIGURE 6.

Each of the arms 7d at its outer end and at the upper and inner portion tnereof has a recess 7S, see FIGURES 2 and 3, which co-operates as hereinafter described in retaining the latch 72. The end plate 68, which is best illustrated in FlGURES l0 to 13, inclusive, has a generally hook-shaped upper end portion t which has a downwardly opening slot S2 machined therein and extending transversel,r of the end fitting for fitting over the supporting flange .3d f the belt rail i6, as clearly illustrated in 3 and 4. Above the downwardly opening slot and at the side of the plate facing the body portion 66, the end plate 63 has a recess de which extends transversely of the end tting and the opposite ends of which communicate with the recesses '73 formed in the upper inner portion or the arms 74 of the body `66.

the end plate extends downwardly from its hoolishaped upper end portion il@ along the belt rail i6 and includes a lower end portion which, when the slot 82 is iitted over the supporting flange of the belt rail, faces the vertical belt rail portion .16 in which the spaced apertures 56 are termed. This lower plate portion has a pair of spaced apertures 36 which are best illustrated in FlGURE ll and which are spaced to be aligned with certain of the apertures ti in the belt rail. ln the preferred embodiment illustrated the spacing between the apertures S6 is double the spacing between the apertures 5@ in the belt rail. intermediate the apertures 86 the lower portion of the end plate 68 has a boss 8S adapted to engage the belt rail portion itl when lthe end plate is disposed with the belt rail supporting iiange 34 received in the end plate slot 82. It will be noted that, as best illustrated in FIGURES 7 and l0, the boss 88 is of oval shape and extends above the elevation of the holes the belt rail so that it cannot move into these apertures The lat-ch 72 is disposed within the opening 7d defined by the U-shaped body portion and the end plate 6%. The latch inelules an upper supporting portion or mounting pad which is received in the recess Sd extending transversely of the end plate and has its opposite end portions received in the recesses 7S formed in the adiacent upper end portion the arms 74 of the body 66. From a complete understanding of the construction illustrated and described herein, it will be appreciated that the latch 72 must be in place within the latch opening 76 and with the` latch mounting pad du received in the end plate recess Se and in the body arm recesses 7 8 before the end plate 68 is welded to the outer ends of the arms 7d. rEhe weld symbols indicated in FEGURE 6 are intended to indicate a continuous weld along the line 76. At its upper end the latch 72 also includes a centrally disposed handle portion Q2 integral with the mounting pad 9b and extending in a direction away from the end plate 63 and movable between the arms 74 of the body portion. The latch 72 extends downwardly between the body arms 74 and carries a pair of spaced parallel pins @d which extend into the apertures 36 in the lower portion of the end plate 68.

it will be noted that the mounting pad 99 and the recess 84 are formed to permit swinging of the lower end of the latch 72 about the engagement of the mounting pad 96 with the end plate 6d to move the pins between the engaged position illustrated in FlGURE 3, in which the pins M extend through the apertures S6 in the end plate 66 and through the apertures in the belt rail, and the retracted position illustrated in FIGURE 4 in which the pins gli are withdrawn from the apertures 5d of the belt rail. For this purpose mounting pad 9% is tapered as best illustrated in FEGURES 6, 8 and 9 and the walls of the recess de taper at a substantially larger angle, as best illustrated in FlGURE 6. The lower end of the latch 72 includes a projection 96 extending in the opposite direc*V tion from the pins Mi and adapted to be engaged by the operator for effecting movement of the latch between the' engaged retracted positions. lt is. a feature of they present invention that the projection 96 engages the body portion 66, as illustrated in FlGURE 4, to limit movement of the latch in a direction to withdraw the pins 94 from the end plate apertures 86. lt will thus be appreciated that during assembly, when the latch 72 is put in place preparatory to welding of the end plate 68 to the body 66, the pins @d of the latch project into the apertures 86 of the end plate 68. Once the end plate 86 has been welded in place, along the line 76 of FlGURE 6, it is impossible for the latch to fall from the opening 711 defined by the body and the end plate, both because the upper end of the latch cannot be removed from the recesses S4 and 7S and because the pins 94tcannot be withdrawn from the end plate apertures 66. lt will be noted that the outer ends of the pins 9d are rounded as indicated at 98 and that thc lower portion is relieved as indicated at 11W to facilitate insertion of the pins 94 into the belt rail apertures 5t) and prevent interference between the pins @d and the end plate 68.

A spring 1111 in carried by the latch 72 for urging the latch toward the engaged position. This spring is generally in the shape of an inverted U and is received within a recess formed in the latch at the side thereof opposite the end p ate 68. One end of the spring 161 is secured to the latch by a rivet 104.

Attention is directed to the fact that the width of the latch 72, intermediate the mounting pad gli and the lower end portion carrying the pins 9d, is slightly less than the spacing between the body arms 74 and that the mounting pad @it has a loose fit in the recesses 84tand '78 which permits sufcient lateral movement of the lower end of the latch 72 so that any loads imposed on the pins 941 by the belt rail 16 will be transferred by the pins directly to the end plate 68 at the sides of the apertures 36 in the end plate.

From the foregoing description, it will be appreciated that in using a crossbar 18, having end fittings of the construction of the present invention, the crossbar is put in place by engaging the hook-shaped upper end portions 8d of the end plate 63 over the supporting anges 3d of the belt rails so that the end fitting at each end of the crossbar receives the supporting flange 34 in the transverse slot 82 thereof so that the end tting is supported on the upper edge surface of the support ange 34. The latches 72 may then be held in the retracted position illustrated in FGURE 4 by engaging the projection 96, or the projection 92, if the latter is more readily accessible. With the latches held in this retracted position the bar may then be slid along the belt rails to the desired adjusted position. rl`he latches are then released and the pins 94 permitted to be moved into the apertures 5u of the belt rail 16 under the action of the spring 1111. 1t is noted that the point at which the mounting pad @il engages the end plate 6d to support the latch is such that the center of gravity of the latch acts to move the latch in a direction toward or retain it in its operative or engaged position illustrated in FIG- URE 3. in the preferred embodiment illustrated in FlG- URES 1 to 13, inclusive, the end fittings Ztl and 22 may be formed of forgings requiring a minimum of machining and affording a very rugged construction.

ln the modified form of the present invention illustrated in

FEGURES

14 and 15, the end litting 111B diiiers from the end fitting 22 in that the pins 112 are separately formed and are slidably mounted for movement along their axes in apertures 114 provided in the end plate 116 and corresponding to the above described apertures $6, and in aligned apertures 113 provided in bosses 126 integrally formed on the end tting body portion 122 and projecting downwardly therefrom as viewed in FGURES 14tand l5. The pins 112 are moved between the engaged or operative position illustrated in FlGURl-E 14 and the retracted position by an actuator lever 124 pivotally mounted in the end fitting body 122 by pivot pin 126 extending transversely thereof, the lower end of the actuator lever 124.- having spaced yoke portions 12S` which engage between spaced collar portions 13o and 132 provided on the pins 112. The actuator lever plate 124i is urged to the position illustrated in FIGURE 14, in which the pins are held in the operative or engaged position by a spring 134, one end of which fits over a spring guide projection 136 on the rear of the end plate 116 and the other end of' which fits over a spring guide projection 136 formed on the actuator lever plate 12d. lt will now be appreciated that by engaging the upper end of the lever 124 it may he pivoted in a counterclockwise direction, as viewed in FIG- URE 14, to withdraw the pins 112 from the `apertures 1610 in the belt rail 1112. r1`he end fitting 11@ may then be readily slid along the belt rail 142 or raised to completely disengage it from the belt rail 142.

FIGURES 16 and 17 illustrate another construction embodying dilerences in both the belt rail and the end fitting. 1n this construction the belt rail 15@ is generally Z-shaped and includes an attaching harige 152 which is welded to the boxcar wall lil as indicated at 154, a vertical supporting flange 156 parallel to and offset from the attaching flange 152 and an interconnecting portion 158. The supporting ilange 156 has a plurality of longitudinally spaced apertures 16@ extending horizontally therethrough.

The end fitting 162 includes a shaulr 164 similar to the shanlf` 6d. The body portion 166 of the end fitting is generally cup-shaped, having the shank 164; integrally formed therewith and disposed generally in the position of the cup handle. 1n opposed relation to the shank 164, the body portion 166 carries a pair of laterally spaced pins 16S which extend parallel to the shank 164i and are spaced for insertion into the belt rail apertures 16d. When the end fitting is connected to the belt rail as illustrated in FIGURE 16, withdrawal of the pins 16S from the belt rail apertures 161B is prevented by a latch 171i which is pivotally connected to the body portion 166 by a pivot pin 172 extending through the latch and disposed transversely of the body portion 166 and parallel to the belt rail 151i. The latch 171B has a hook portion 174 extending generally parallel to the pins 16S and adapted, when the pins are inserted through the belt rail apertures 160, as illustrated in FlGURE 16, to extend over the upper edge of the belt rail supporting flange 156 and to turn downwardly to the pins 163. The downwardly extending portion 176 of the latch is thus disposed in the space between the belt rail supporting `ilange 156 and the side wall 1li. lt will thus be appreciated that this portion 176 of the latch will prevent movement of the fitting 162 in a direction away from the belt rail, or to the right as viewed in FlGUP-.E 16, to withdraw the pins 163 from. thebelt rail apertures 166, by engaging the inner face 173 of the belt rail supporting flange 156.

ln the preferred embodiment illustrated, the pivot pin 172 extends through a transverse pivot boss 186 formed on the latch and is a pressed fit therein. The opposite ends of the pivot pin 172 extend outwardly of the latch pivot boss 131i and are loosely journalled in apertures 182 provided in the body portion 166. The pivot boss 1863 of the latch extends into recesses 164i formed in the opposite side Walls of the cup-shaped body 166. The bottoms of the rcesses 1841, as viewed in

FGURES

16 and 17, provide shoulders 166 which pivotally support the pivot boss 1531) to permit any loads to be transferred directly from the latch pivot boss 136 to the body portion 166. The latch 17d has a handle portion 188 which is of reduced width as illustrated in FIGURE 18, which extends generally in the opposite direction from the hook portion 17d and is movable within the cup-shaped body portion 166 for pivoting the latch in a clock wise direction from the engaged position illustrated in FIGURE 16 to a disengaged position in which the hook portion is raised clear of the belt rail so that the pins 16S may be withdrawn from the belt rail apertures 160. The latch 1711 is yieldably held in the engaged position illustrated in FIGURE 16 by a spring 19t) disposed within the body portion 166 and having its lower end fitted over a spring guide projection ig?, formed on the body portion lod and the upper end of which fits over a spring guide projection i94- formed on the under side of the latch handle i188.

Movement of the end fitting i E?, to the right, as viewed in FIGURE 16, which is in a direction to withdraw the pins 168 from the belt rail apertures Tied, is prevented, as pointed out above, by engagement of the downwardly extending portion l'ti of the hook section i174 of the latch, with the surface iri of the belt rail. This engagement tends to pivot the latch 1170 in a counterclockwise direction. Such movement of the latch is positively limited by the engagement of the above mentioned surface 196 of the latch with the co-operating surface i9@ forming a part of the inner wall surface of the body portion E66. Because of this engagement, this movement of the end fitting in a direction to WithdrauI the pins cannot impose any excessive loads on the pivot pin 172.

While only three specific embodiments of the invention have been illustrated and descrived herein, it will be readily appreciated by those skilled in the art that numerous modiiications and changes may be made without departing from the spirit of .the present invention.
