Abstract
Abstract A movable bulkhead assembly and associated flat bedded railway car. The bulkhead assembly is movable to any of a plurality of preselected positions longitudinally of the car for bracing freight carried on its bed. The bulkhead is supported for such movement upon spaced tracks and the bulkhead assembly includes a supporting arrangement that engages the tracks for facilitating movement of the bulkhead assembly regardless of misalignment of the tracks, a drive mechanism for moving the bulkhead along the car and a locking mechanism for restraining the bulkhead in selected freight bracing positions. A safety mechanism is provided for preventing inadvertent operation of either of the drive or locking mechanisms.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
In a movable bulkhead assembly adapted to brace freight in a cargo lading area and having a bracing member adapted to engage and brace such freight, drive means for moving said bracing member between preselected bracing positions relative to the cargo area, and locking means for releasably restraining said bracing member in such preselected bracing positions, the improvement comprising safety means movable between an engaged position and disengaged position, said safety means being interrelated to said drive means and said locking means for precluding operation of either of said drive means or said locking means when said safety means is in its engaged position and for permitting operation of either of said drive means or said locking means when said safety means is in its disengaged position.
Claim 2
Dependent Claim
127 words
In a movable bulkhead assembly adapted to brace freight in a cargo lading area and having a bracing member adapted to engage and brace such freight, drive means for moving said bracing member between preselected bracing positions relative to the cargo area, and locking means for releasably restraining said bracing member in such preselected bracing positions, the improvement comprising safety means movable between an engaged position and disengaged position, said safety means being interrelated to said drive means and said locking means for precluding operation of either of said drive means or said locking means when said safety means is in its engaged position and for permitting operation of either of said drive means or said locking means when said safety means is in its disengaged position.
Claim 3
Dependent Claim
33 words
A movable bulkhead assembly as set forth in claim 1 wherein the drive means includes an operating handle, the safety means including means for latching said operating handle relative to said locking means.
Claim 4
Dependent Claim
110 words
A movable bulkhead assembly as set forth in claim 1 wherein the cargo lading area is formed by a movable freight-transporting vehicle subjected to shock loadings, the locking means includes an actuating handle supported for pivotal movement between a locking position and an unblocking position, the pivot axis of the actuating handle extending transversely to the directions of shock loading whereby shock loadings on the freight-transporting vehicle tend to cause pivotal movement of said actuating handle, said safety means being effective to preclude pivotal movement of said safety means being effective to preclude pivotal movement of said actuating handle from its locking position to its unlocking position under shock loadings.
Claim 5
Dependent Claim
38 words
A movable bulkhead assembly as set forth in claim 3 wherein the drive means includes an operating handle, the safety means including latching means for retaining said operating handle in a fixed position relative to said locking means.
Claim 6
Dependent Claim
57 words
A movable bulkhead assembly as set forth in claim 1 wherein the drive means comprises a driving shaft and an operating handle for rotating said driving shaft, the locking means comprising a torsion shaft and an actuating handle for rotating said actuating shaft, said operating and said actuating handles being supported for pivotal movement about parallel axes.
Claim 7
Dependent Claim
31 words
A movable bulkhead assembly as set forth in claim 5 wherein the safety means includes latching means for latching the free end of the operating handle relative to the torsion shaft.
