Elongated horizontally extending through apertures 135 are provided respectively in runner assemblies 127 and provide access means to the railway car air supply line valves 97; when carrier unit 13 is supported on railway car 11 a respective opening 135 aligns with a valve 97 and permits coupling 101 of the hose assembly to be engaged with the valve and to charge the base structure tank means of the carrier with compressed air. End portions 136 respectively of side rail members 35 of railway car 11 are turned inwardly (see FIGS. 3 and 4). The inwardly converging rail portions 136 are adapted to engage paired rollers 131 of each carrier unit 13 and to longitudinally center the carrier -unit crosswise over the railway car.
Steering mechanism is provided at the front of each wheeled carrier unit 13 (see FIG. 7). A center link 137 is pivoted at the rearward end thereof about a vertical axis disposed forwardly of front axle 41. A pair of tie-rod members 139 connect center link 137 to each front wheel 43 and the front wheels together. The steering mechanism includes front hitch means and such means for trailingly attaching the carrier to a towing vehicle or to another carrier unit. The hitch means includes a tongue 141 pivoted at the rearward end thereof to center link 137 and turnable about a horizontal axis. A pivotable bracket 143 is mounted on the front of each carrier unit base structure t0 hold tongue 141 in a vertical position when the carrier unit is being transported by rail. Rear hitch means is provided for connecting two or more carriers together: a tubular member 145 is transversely attached to rear axle 41. A hitch bar 147 having a plurality of apertures 149 is slideably received in tubular member 145. A pin 151 insertable in a selected one of apertures 149 adjusts the extension of hitch bar 147.
Each carrier unit 13 includes binding means removably binding shell 46 on base structure 45; a manually operative overcenter lever type binder half 153 is mounted on each corner of base structure 45 and coacts with a fixed binder half or binder bar 154 mounted respectively on each lower corner portion of shell 46 (see FIGS. 5 and 18).
Anchoring means removably anchor the carrier units on the railway car. The anchoring means includes stakes 155 secured on rail car 11 and runner assemblies 127 secured on each carrier unit 13. Stakes 155 removably secured in sockets 157 in rail car frame 15 secure the transversely juxtaposedly arranged plurality of carrier units against lateral displacement on the rail car frame; parallel runner assemblies 127 engage the opposite side rails 35 of the railway car and secure each carrier unit against longitudinal displacement on the rail car frame. The centering and the anchoring means of the railway car and each carrier unit are relatively operative in that, parallel spaced assemblies 127 engage rail car side rails 35 and provide a dual function in longitudinally centering each carrier unit crosswise over the rail car frame, and in anchoring each centered carrier unit against longitudinal displacement on the rail car frame.
In use, when it is desired to transfer a carrier unit 13 from roadway to railway travel, the carrier unit is pulled to a halted position crosswise over the rail track by such means as tow tractor 12, and base structure 45 is raised by the pneumatic jack means of the carrier unit. Railway car 11 is moved under carrier unit 13; as the railway car is moved under the carrier unit the converging end portions 136 of the railway car frame engage rollers 131 of runner assemblies 127 and longitudinally center the carrier unit crosswise over the frame of the railway car. When railway car 11 is correctly positioned underneath carrier unit 13 the base structure of the carrier unit is then lowered on to the frame structure of the railway car by turning control valve 109 to the lower position. With the carrier unit base structure resting on the frame of the rail car, springs S retract carrier unit wheels 43 from the ground and the carrier unit is then ready for rail transporting. When it is desired to transfer a carrier unit from railway travel to roadway travel, the above-described procedure is substantially carried out in a converse manner.
