The drawworks control the drilling depth by raising and lowering the drilling assembly.
[pdf] Peter Sweeny, building on Robert Beart's earlier design, made a huge advancement in rotary drill technology, enabling almost continuous drilling. His new design also improved on hole cleaning. .
Charles Burleigh, John W. Brooks, and Stephen F. Gates patented a mechanical drill meant to be used on the Hoosac tunnel: the compressed air Burleigh drill. The tunnel spurred several innovations in drilling technology, including the earlier Couch/Fowle drill.. .
