From the text: Fig 2770. Murray alternating current direct-connected unit with high speed Corliss engine and belt-driven exciter, 50, 75, 100 KVA alternator and 150 RPM engine.
Note: This image is only about 3 inches wide and 1.5 inches tall in the book -- a testament to the high printed-image quality of these 90 year old engineering books that cost $1 per volume in 1917.
