540 Report of the Judges of Implements at Norwicli. 
the after-operations of the machine, which are taken from the 
drum spindle, are kept at a uniform speed, and consequently 
are always operating as they should be. The feeder also forms 
a safeguard round the drum, and, taking up very little room, 
does not in any way interfere with the ordinary platform of the 
machine. To this article a silver medal was awarded. 
Messrs. Ransomes, Sims and Jefferies, No. 3849, Digging 
Plough with Patent Divided Share. — This plough, adapted for 
digging work, is fitted with a new Plough Share, patented by 
Mr. James Edward Ransome, grandson of Mr. Robert Ransome, 
founder of the firm, which, instead of being made, as is usually 
the case with shares for digging-ploughs, of one heavy casting, 
is divided into four parts, so that those parts most accustomed 
to wear can be more cheaply renewed. The share consists of 
a box. Fig. 14, p. 539 (a), to which is fitted a point (c), forming 
the point of the share, the wing (b) forming the bottom cutting 
blade, also the cutter (d) which serves as a coulter, and which 
is held in its place by a projection in the fore part that fits into 
the box. The wing of the share is supported by a groove in the 
box, and is held in position by two bolts attached to the frame 
of the plough, so that it is not liable to breakage ; and the roots 
of weeds, twitch grass, &c., cannot get between it and the bottom 
part of the share. 
Messrs. Foden and Sons, No. 3976, Compound Traction 
Engine, fitted with their spring sliding axle-box, is provided 
with a special arrangement by which the compound actions 
maybe instantly suspended, and both cylinders may take high- 
pressure steam, exhausting directly and independently into the 
chimney, the steam being supplied in such a manner that each 
cylinder shall give off the same amount of power. The object 
of such an arrangement is to give increased power to the engine 
when starting or doing exceptionally heavy work, as on a steep 
gradient or when getting over soft ground. It is effected in the 
following manner : in the passage between the high- and low- 
pressure cylinder, a three-way cock is fitted, this cock being 
actuated either by an independent lever or else by the starting 
lever. In ordinary work, the steam from the high-pressure 
cylinder passes into the larger (or low-pressure) cylinder, is 
there further expanded, and exhausts therefrom into the funnel. 
If, in case of emergency, it is required to get more power out 
of the engine, the above-mentioned three-way cock is opened, 
so that the exhaust from the high-pressure cylinder passes 
direct into the chimney, which relieves that cylinder of the 
back pressure due to working the low-pressure cylinder, and 
consequently increases its power. Live steam is at the same 
time admitted into the low-pressure cylinder ; but as this cylinder
