content: By the mid-1890s, some American technical publications sold special purpose slide rules to advertise their publications. For example, in 1897 the journal <I>Railway and Locomotive Engineering</I> published this advertisement for Cox’s Train Resistance Computer. The circular slide rule allowed one to calculate “What a locomotive of known draw-bar pull can haul on any grade at any speed.” The name of the journal featured prominently at the center of the instrument. The device was the idea of slide rule designer William Cox. A second circular slide rule designed by Cox, called the “Locomotive Tractive Power Computer” and also advertising <I>Locomotive Engineering</I>, is shown on the following page of the journal. For other examples of circular slide rules associated with Cox, see 1987.0221.01 and 1987.0221.02.
