Hammond Transformers

1917 - Hammond Manufacturing traces it's roots back to a small basement shop set-up during the years of the First World War by Oliver S. Hammond - tool & die maker by day and amateur inventor by night. (Yep...Fred's dad!!! For those who knew Fred - famous radio amateur VE3HC) The company became O.S. Hammond & Son and soon included sons Len, Roy, Ken and Fred. Later Oliver's first "shop" was a 20 by 30 foot facility behind the family home. The shop was powered by a boiler that burned just about anything. The steam from the boiler powered a small steam engine, which turned the main shaft and pulleys. Remember, there was no electricity service yet! Steam power, human power, light of day or lantern was a fact of life!
