“WHATEVER WORKS” HAS A LONG HISTORY – HERE’S PROOF!

I have been making and using mechanical drawings since 1951 and I have NEVER seen a “drawing number” that includes a fraction! I could hardly believe my eyes when I open these drawing image files. I have tried to imagine the situation that existed in 1905 which led to the use of a fraction. The situation I came up with is the draftsman, for some reason, ran out of room  on the first sheet and needed a second sheet to accommodate the last view. The real mystery is the use of a fraction; why not use ‘sheet 2’? Any ideas?

I also realized the content of the two drawings suggested the placement of a steam turbine generator on the tender was at least contemplated; perhaps even tried. I have never heard of this before so I solicit any information that may be available on this subject.

About THE OLD MACHINIST

I am 87 years old and married for 65 years. My wife passed away in 2016. I am a retired engineer and spent 35 years developing INS gyroscopes. I was a High School mentor in physics, a mountaineer, a model builder, a machinist and I have a degree in Physics. My interests include railroad history and photography, science history, cosmology, interesting people, and old engineering drawings. I place a high value on my friendships. I enjoyed my life and I am trying to look forward with a sense of anticipation and curiosity.
