The Locomotive
A periodical issued from 1867 by the Hartford Steam Boiler Inspection and Insurance Company in Hartford, Connecticut, reporting boiler explosions and inspection findings to engineers, plant owners and policyholders. Its engraved plates show boiler staybolts, flanged joints and riveted seams in half-section, with airbrushed tonal shading on cylinders, dotted centre lines and figure captions.
