rod. The catch drops, and with it 

 also the pawl, which latter drops 

 into the ratchet-teeth, k, on the 

 travelling wheel, and is thus at 

 once carried downwards by the 

 revolution of the wheel ; at the 

 same time the rocking-frame u, 

 having the bulk-ends of the tines 

 attached to it, also moves down- 

 wards, and raises the points of 

 the tines. In the course of the 

 revolution the tines are raised to 

 a level with the stripper bar m ; 

 the pawl H is brought into con- 

 tact with, and thrown out of gear 

 by the cam n, which is fixed to 

 the main axle of the rake ; thus 

 the tines are released, and fall by 

 their own gravity. The catch d 

 is arrested by a stop, o, and deli- 

 vered into the original stop f 

 without any jerk. The rule joint 

 is retained in lock by the spiral 

 spring p (see Fig. 47). 



Eac'k travelling-wheel actuates 

 a distinct set of pawls and catches ; 

 thus the rake may be delivered 

 when turning a corner, — one pawl 

 then only being in gear, while 

 the other is over-ridden. The 

 sudden check is avoided, because 

 the same movement which unlocks the joints also starts the lift of the tines.
