An engine reported upon by a committee of the American Institute, of which Dr. Barnard was chairman, was non-condensing, 16 inches in diameter of cylinder, 30 inches stroke, making 125 revolutions per minute, and developed over 125 horse-power with 75 pounds of steam in the boiler, using 25| pounds of steam per indicatcd horse-power, and 2.87 pounds of coal—an extraordinarily good performance for an engine of such small power. The governor used on this engine-is known as the Porter governor. It is given great power and delicacy by weighting it down, and thus obtaining a high velocity of rotation, and by suspending the balls from forked arms, which are given each two bearing-pins separated laterally so far as to permit considerable force to be exerted in changing speeds without cramping those bearings sufficiently to seriously impair the sensitiveness of the governor. (Figs. 7 and 8 show one of these engines, as built by "The Hewes & Phillips Iron Works," Newark, N. J.) This engine as a whole may be regarded as a first-class representative of the high-speed engine of today. |
