Bronze Age Gold from Wales

4 wheeled, narrow gauge (1' 11½") tub or rubble wagon. Wheels are double flanged, are not keyed to the axle and therefore permit some lateral movement. Lubrication is via a wick mechanism, inserted from beneath axle box. RSJ chassis, with hopper mounted above.These are tippable, hinged above front opening, and secured by a catch at the back. Wooden buffering gear, surrounded by wood, at front and rear of wagon. Buffers are not intact. Tipping hoppers come into contact with wooden shock blocks; one original block remains. Handles affixed to facilitate tipping. Used in conjunction with two electric Ruston Bucyrus excavators, for clearing slate rubble at Pen Diffwys tip; also at Hafod Owen and Lernion. Later used at Pant Ceubren tip for transporting rubble to the brick making plant, between 1959-1960. Wagon capacity = up to 5 tons. They were seldom loaded to this capacity as they then became almost impossible to tip. Were sometimes referred to as "American Devil Wagons" = the colloquial name for the excavator. Similar wagons also in use at Penrhyn quarry.
