Claim 6

A railroad car according to claim 1 in which the means for releasably securing the bar first end in a fixed position along the first track includes: a bracket connected to the bar first end; a latch supported by the bracket; latch engaging means on the first track; and means to displace the latch into releasable fixed engagement with the latch engaging means on the first track.

Claim 7

A railroad car according to claim 5 in which the means to displace the latch into releasable fixed engagement with the first track includes spring means.

Claim 8

A railroad car according to claim 5 including means to retain the latch out of engagement with the first track.

Claim 9

A railroad car according to claim 1 in which; the second track has a series of spaced-apart holes; and the bar second end means for releasably securing the bar second end in a fixed position along the second track includes at least one pin which engages a hole in the second track.

Claim 10

A railroad car according to claim 1 in which the bar can be rotated substantially only horizontally about a vertical axis.

Claim 11

A railroad car according to claim 9 in which the bar second end has means engageable with the first track to maintain the bar in stored position resting on the first track top.

Claim 12

A railroad car according to claim 1 in which: the first track is a channel member with inwardly directed horizontal flanges at the top which terminate in spaced apart position and define a longitudinal gap; the means which secures the bar first end to the first track includes a vertical member fixedly attached to the bar and extending downwardly through the gap into the space enclosed by the channel; the vertical member being rotatable about a vertical axis and having a horizontal plate, fixedly connected to it in the space enclosed by the channel, which can be rotated at least about 90° about said vertical axis; the means for releasably securing the bar first end in a fixed position along the first track including a bracket connected to the bar first end; a latch supported by the bracket; the latch being horizontally spaced away from the vertical member axis; and means to displace the latch into releasable fixed engagement with latch engaging means on the first track.

Claim 13

A railroad car having at least one deck for supporting and transporting four-wheel vehicles such as automobiles and trucks; a pair of spaced apart first and second parallel tracks, secured to the deck longitudinally of the railroad car, having clearance for the two wheels on one side of the vehicle to roll between the tracks; a pair of movable chock block means for each vehicle transported on the deck to secure the vehicle against longitudinal movement; each chock block means including a bar with a first end and a second end; the bar first end having means which permanently secures the bar first end to the first track so that it is not readily removable from the first track but so that the bar first end can be moved along the longitudinal axis of the track and the bar also can be rotated from about lateral to about parallel to the track; the bar first end having means for releasably securing the bar first end in a fixed position along the first track including a bracket connected to the bar first end, a latch supported by the bracket, and means to displace the latch into releasable fixed engagement with latch engaging means on the first track; the second track having a series of spaced-apart holes; the bar second end having means for releasably securing the bar second end in a fixed position along the second track including at least one pin which engages a hole in the second track wherein said pin is fixedly secured to said bar second end and substantially horizontal thereto so that release of the pin at the bar second end from a hole in the second track requires displacement of the bar first end along the first track for a short distance.

Claim 14

A railroad car having at least one deck for supporting and transporting four-wheel vehicles such as automobiles and trucks; a pair of spaced apart first and second parallel tracks, secured to the deck longitudinally of the railroad car, having clearance for the two wheels on one side of the vehicle to roll between the tracks; a pair of movable chock block means for each vehicle transported on the deck to secure the vehicle against longitudinal movement; each chock block means including a bar with a first end and a second end; the bar first end having means which permanently secures the bar first end to the first track so that it is not readily removable from the first track but so that the bar first end can be moved along the longitudinal axis of the track and the bar also can be rotated from about lateral to about parallel to the track; the bar first end having means for releasably securing the bar first end in a fixed position along the first track including a bracket connected to the bar first end, a latch supported by the bracket, and means to displace the latch into releasable fixed engagement with latch engaging means on the first track; the second track having a series of spaced-apart holes; the bar second end having means for releasably securing the bar second end in a fixed position along the second track including at least one pin which engages a hole in the second track wherein said pin is fixedly secured to said bar second end and substantially horizontal thereto so that release of the pin at the bar second end from a hole in the second track requires displacement of the bar first end along the first track for a short distance.
