jblit, arc of steel, and have their front-ends pivoted on the bar b, which is 
rried by the frame c, which is capable of being moved ronud the mam axle 
a centre ; over the frame c, and turning on bearings attached to it, are the 
wl-bars D, divided in the centre of the rake, and carrying at their outer 
d6 a pawl, E, and on their inner ends the stops f. The lever H is jointed 
Iff its middle to an arm of the frame c, and its outer end has a rule-joint, 
by which it is attached to the hand-lever l. On the cranked arm of this 
TCf is a treadle, J, which can be depressed by the foot of the driver, or by 
e hand-lever l being pulled towards the seat-iron k, or the inner end of H 
ted up. The lock formed bj' the rule-joint i is broken, and the stud, as 
own above the letter f, attached to the lever h, is depressed, releasing the stop 
which held the pawl e from falling into the teeth of the ratchets formed 
both the bosses of the carrying-wheels. Upon the pawl e thus falling into 
ar, the revolution of the wheels carries the frame c with them, and thereby 
ts and empties the rake-teeth. When the rake-teeth have been lifted high 
ough the cam m throws the pawl e out of gear with the ratchet, thereby 
owing the teeth to drop back into the proper position for raking. By 
iving duplicate pawls, and the pawl-bar in two parts, it allows either carry- 
5-wheel to lift the rake-teeth independently of the other, which enables the 
ke to be discharged when turning round without causing the wheels to skid. 
ig. 34. — Section of Messrs. Nicholson and Son's Self-acting Horse-rake, 
No. 1037. 
The adjustment for regulating the height of the teeth from the ground is 
ade by raising or lowering the bar n n, shown in two positions, by the 
tew P. This gives a rise of I5 inch above the ground, and a fall of 1^ inch 
to it, as shown by the dotted and plain lines of the tooth a. The bar N x 
divided into two at the centre of the rake, the ends of each section being 
ted with adjusting screws, so that the centre teeth of the rake may be 
wred whilst the end ones are raised, or vice versa, and thus regulated to 
6 inequality of the groimd to be raked.
