Blueprint for Engines at Edison Central Station – Armington & Sims 18” x 18

Drawing
This document is a blueprint containing technical specifications for engines used at Edison Central Station, specifically an Armington & Sims 18” x 18” engine. The document consists of a data table listing various values related to boiler pressure, steam consumption, and efficiency at different cutoff points. Additional notes at the bottom describe operational considerations, including steam consumption and clearance percentages. The document is signed by W.J. Murtfeldt, Superintendent of Tests.
