Agricultural Locomotive Engines
For working threshing machinery, for steam cultivation, sawing, pumping, &c, for removing agricultural produce, and in fact for all purposes to which steam can be applied as a motive power in farm work, the agricultural locomotive is far better adapted than a mere portable engine.
Fig. 15 is an engraving of one of Ransome, Head, and Jefferies' agricultural locomotive. These engines are made in two sizes, viz. 6 and 8 horsepower, and are arranged to travel at two different speeds, viz., about 1½ and 3 miles per hour.
They are constructed from the newest designs, and the general arrangement is the result of a long and varied experience with this class of machinery.
A winding drum working on the main axle can be fitted to these engines; and by means of a wire rope the whole power of the engine can be brought to bear upon the threshing machine, so as to draw it out of any extra difficult situation while the engine remains stationary. This is an extremely useful addition, as all those who are accustomed to them will see at once.
These engines can be fitted with double slides when required, so as to make full use of the expansive power of the steam. They can also be fitted with a new patent automatic governor, acting direct on the second expansion-slide by means of a link motion. This is a very valuable arrangement when an engine is required to drive machinery in which the load is constantly varying, at one time taking the full power of the engine and at others but a small portion of it. For sawing machinery, crushing-mills, &c, it is very useful, as only the exact amount of steam required at each instant is admitted into the cylinder, and a perfectly uniform speed is always maintained. |
