The Locomotive
A technical periodical issued from 1867 by the Hartford Steam Boiler Inspection and Insurance Company in Hartford, Connecticut, reporting boiler explosions, inspections, and machinery practice to engineers, plant owners, and policyholders. Halftone photographs of shop machinery, ruptured plate, and corroded tube sheets sit beside line-drawn sectional diagrams of boilers, piping, and valves, giving designers grainy industrial detail, hatched cutaway conventions, and isolated fragments of damaged metal.
