Fig. 4 shows a twin compound agricultural locomotive made by Messrs. Foden Sons & Co., of Sandbach. The cylinders are steam jacketed and well lagged. The front cylinder covers have each a cylindrical guide cast with them as shown. The guides are bored and turned at one setting, which makes them absolutely central with the bore of the cylinders. On the top of the guides is fixed a Porter governor which actuates a throttle valve in a direct manner. The sides of the box brackets are made of boilerplates, riveted to the arch plate, and stiffened by transverse plates.
All Messrs. Foden's engines are mounted on springs. The axle and the countershaft are securely held together by links on each side, and the bearings for both these shafts slide in a strong bracket. On the top of each bracket there is a circular box containing a large square steel spiral spring. The weight of the hind part of the engine and the boiler, passes through the springs to the main axle. There is also a similar spring on the fore axle, kept in place by a cylindrical turn plate.
The tires of the driving and leading wheels are made of tough cast-iron, the former being shod with steel diagonal strips. The driving wheels are nearly seven feet in diameter; the advantages of large drivers are too well known to need any remark here. It will be noticed that a larger number of spokes are adopted than usual, the iron being of a smaller section. The water in the supplementary tank under the boiler barrel, is heated by a portion of the exhaust steam. The pump draws its supply from this tank. |
