Text Appearing Before Image:
ed the University by the Railroad Company. The figuresabove the profile indicate the grade in feet per mile, those belowthe height above sea level. In order that a more careful comparison of the two enginesmay be made, more detailed curves are plotted on Plates VI, and VII,showing the performances of the two locomotives on two heavy grades.Plate VI is for the Paxton grade, and Plate VII for the grade justnorth of Kankakee. As will be seen the position of the reverselever, throttle opening, speed in miles per hour, draw-bar pull,boiler pressure, indicated horse power and draw-bar horse power areplotted for the two engines. Thus at any point one is enabled tosee how either engine is working. The data plotted for the 920 isthe second trial to get over the hill with its train, after one un-successful attempt. It will be noted that the steam pressure of the920 was lower than that of the 940, also that the 920 was workedwith a longer cut-off, full throttle opening being used on bothengines.
