Messrs. John Fowler and Co., Leeds, amongst their steam- 
ploughing machinery, had an eight-horse-power Double Drum 
Engine on a new principle, and which certainly looked a great 
improvement on those hitherto made. A set of roundabout 
tackle was at work with one of these engines in a field near the 
Yard, and gave people a very good idea of its capabilities. One 
drum is hung under the boiler in the usual position, and is driven 
by an upright shaft ; on this shaft, immediately above the lower 
bearing, is a bevel-wheel, giving motion to a horizontal shaft 
running alongside the fire-box ; and this, by means of bevel- 
gearing, drives a short vertical shaft with a pinion-gearing into 
the hinder drum, which is carried on a stud fixed on the bottom 
of the tank, this being made strong enough to withstand the 
strains put upon it. 
The engine can be worked in three ways — (1) Along the 
headland opposite to a self-moving anchor, and so have a 
direct pull upon the implement ; (2) remaining stationary, and 
working with two self-moving anchors ; or (3) as one of a pair 
of engines. 
The makers do not claim that this principle is better than 
a pair of engines, but that it is a most efficient single engine 
set, embodying, as far as possible, the advantages of the double 
system. 
The anchor used with this tackle is entirely self-acting ; it 
is moved along the headland by the direct pull of the hauling- 
rope ; and the distance it moves forward each bout can be con- 
trolled by the ploughman without his leaving the implement.
