Fig. 114 is a representation of Fowler's ploughing engine, in which it will be seen there are two drums rotating on vertical axes beneath the boiler, on one of which the engine is winding up the wire rope, drawing the frame of plough shares, while the engine at the opposite side of the field is at the same time winding up the other rope, and consequently unwinding it from the drum here represented. In point of fact an endless rope would answer as well as two ropes, and an endless rope may be made to work two sets of ploughs by being passed over a movable pulley at the opposite side of the field without the necessity of using two engines. The single engine, however, would require to have the same power as the two it superseded to do the same work in the same time, and there would be the trouble and delay incidental to the moving of the pulley and its anchors while the weight of an engine constitutes anchor enough. All things considered therefore, the plan of having two engines and two ropes passing across the field appears to be the best yet introduced. |
