Seeing this article in latest ME took me back to my first days at work.
At the tender age of 15 in Jan 1957 I joined Alldays & Onions in Birmingham as an apprentice.
At the time Alldays made industrial fans, rootes blowers, smithy equipment and pneumatic and steam hammers.
We had a separate shop, called appropriately, the hammer shop. This shop had a floor surfaced with massive wood sections to absorb the shock. Every hammer was tested and I vividly remember seeing a man running through the main works trailing sparks behind him from a large bar of red hot steel from the smithy we had there.
Despite the wooden floor the whole place trembled when the large hammers were being tested. At the back of the same shop the Rootes blowers were built and tested, they ran for several hours and I walked back home with a throbbing droning noise in my ears.
I have a couple of old catalogues from the late 1800's, a feature of catalogues of this era seemed to describe everything as a 'Patent xxx or 'New improved xxx.
Happy days.
