Samuel Bacon Hillocks (February 11, 1869 – 1937) was a politician, Presbyterian minister and inventor of the Grain Door.
[1] Hillocks was one of the two ministers who presided over the Union Service in Calgary, Alberta, after the death of King Edward VII on May 20, 1910.
He defeated Liberal candidate George Henry Ross to win a term in office.
Hillock would run again in the 1921 Alberta general election attempting to regain a seat in the legislature, he would be badly defeated in the new block vote system and finish a disappointing 18 place out of 21 candidates.
Hillocks invented the Grain Door and was issued a patent by the Canadian Intellectual Property Office on May 24, 1938.
