I still haven't found what I was looking for, which was a reference to a printing press being hauled out of th American Litho building by crane in (I think) 1919 and crashing through the sidewalk and into the Lexington Avenue subway, killing a hapless bystander but I was trolling through Google Books when I came across this, which is a lawsuit arising out of an accident at a firm I have to think was similar American Litho around 1910-11. Read the whole case and you will see the pressroom in question had seventeen printing presses:

I found another suit from the same time concerning a fourteen year old girl who got her hair caught in some machinery in a room at American Litho where they stitched pamphlets together:

Conditions must have been ghastly as this was around the time of the Triangle Shirtwaist Fire.
