Bangor's Hinkley & Egery Ironworks (later Union Ironworks) was a local center for invention in the 19th and early 20th centuries. A new type of [[steam engine]] built there, named the "Endeavor", won a gold medal at the [[New York Crystal Palace]] Exhibition of the American Institute in 1856. The firm won a diploma for a shingle-making machine the following year.<ref>{{Cite book|last=York|first=American Institute of the City of New|url=https://books.google.com/books?id=qeRIAAAAMAAJ&dq=Annual+Report+of+the+American+Institute+of+the+City+of+New+York+1856&pg=PA73|title=Transactions of the American Institute of the City of New York|date=1864|publisher=C. van Benthuysen.|language=en}}</ref> In the 1920s, Union Iron Works engineer Don A.
