The novelty as regards the engine consists in the use of two vertical winding 
drums, which are mounted on either side of the boiler, and are driven directly 
from the crank-shaft of the engine. The use of two drums is for roundabout 
cultivation ; if intended for the double engine system, one driun only will be 
required to each engine. The hauling drums are mounted loosely on stud axles 
made fast to the skin of the boiler. They are cast with a ring of spur teeth 
into which gear pinions, which slide on feathers on the crank-shaft. This 
shaft is mounted above the barrel of the boiler, and carries two spur-wheels of 
diflerent sizes, which gear into wheels on the counter-shaft, for giving two 
different speeds. On one end of the counter-shaft is a spur pinion, which gears 
into a spur-wheel keyed to one end of a second counter-shaft, which carries at 
its opposite end a spur-pinion for driving, through a spur-wheel, the axle of 
the traction wheels. This is strong, simple, and direct gearing. This arrange- 
ment, moreover, allows of the winding-drums being placed close to the boiler, 
so that no extra width is required. The ropes as they leave the dram may 
be led off in any required direction. As regards the rovmdabout system, this 
invention removes the necessity for a separate windlass. A strong india- 
rubber pad is placed between the boiler and the fore carriage. The catalogue 
price of a 10-horse-power engine is 580?. 
The improvements in the travelling anchor, which in its main features 
resembles that of Campain, consists in the addition of a semaphore or other 
signal, and the action of a movable lever rod, which, when pressed in by a 
ball or other opposing medium on the rope, causes a stop to be withdrawn, 
and thus liberates the axle carrying the claws, and allows the tension of the 
rope to move the anchor forward on the head-

driver that the cultivator has completed a 
" bout ;" and he will continue the action on 
the hauling rope to move forward the anchor, 
until a signal from the man on the cultivator 
warns him to stop the progress of the anchor 
and reverse the engine. The effect of this 
reversal will be to release the swinging frame 
from pressure and to cause the semaphore arm 
to drop (Fig. 41). A, Telegraph standard; 
B, leverage rod, connected with c, the movable 
bar. The end of the movable bar acts on a 
stop, D, which prevents the claws moving. 
When the ball on the roi)e comes in contact 
with the bar, c, the latter is pushed in, with- 
drawing the catch, D, and liberating the claw, 
which no longer keeps the anchor fixed. ,At 
the same time the telegraph arm goes out, and 
remains so whilst the anchor travels. The 
price of this article is bOl. 
The third and last invention or improvement 
that I shall notice relates to a snatch block, 
which is capable of being traversed along the 
road to its work. It consists of a frame, made 
of bar-iron, bent at its rear end into the form 
of a triangle (see a a. Fig. 42), and continued 
forward to form a forked bearing for a roller, b. 
BctAvetn the fork and the triangle the frame is 
fitted with a stud-pin, c, for receiving the guide pulley, d, around which the 
liauling rope for the engine is passed. Mounted on the triangular portion ol
