The agricultural locomotive shown in Fig. 9 and built by Messrs. Mann & Charlesworth, of Leeds, possesses several novel features. The ordinary link motion reversing gear has been dispensed with, and in its place the firm's patent single eccentric reversing gear has been applied. This enables one eccentric and rod to do all that is required in working expansively when running forward or backward, and for reversing the motion. The eccentric is shifted from full forward to full backward without altering the lead. Its movement resembles that of the parallel ruler, as in any position it remains parallel to the centre line of the engine and at right angles to the crankshaft. There are three bearings for the crankshaft, and the driving pinions for the two speeds are placed between two of these bearings, but outside the box bracket. The governor is fixed over an equilibrium throttle valve in the cylinder. By using steel castings in place of cast iron, the weight has been considerably diminished without reducing the strength, or limiting the efficiency. |
