Sorry, no etymologies found.
For spans over 75 ft., expansion due to change of temperature is provided for by carrying one end of each chain girder on rollers placed between the bearing-plate on the girder and the bed-plate on the pier or abutment.
This he must regulate, either by one of the guns in his vicinity, or, better, by the aid of a bearing-plate, a species of plane-table which gives the angular bearing of the object.
