Can anyone on the list please help me with this one?
My grandfather invented a machine originally called the Caunch Billdozer. This machine was used to clear stones from rippings by contriving a Bull-dozer shovel to discharge the stone to the A.F.C. As my gand fatherworked for the National Coal Board he was obliged to sell his idea to them and could not patend it. A Mr Lang later claimed it to be his idea in an article in Coal News, a monthly publication. (I have all documentaion, including grandad's original drawings)
Have you heard of the Billdozer and is it still used today around the world as rumoured by some of my family members?
Have you any pictures?
