a slip of sheet-iron close to the fingers (Fig. 20). The main driving-wheel

fitted witb spur-pinions which gear into the segmental elevating racks. The 
axle is turned by a chain woxmd round a small drum, and actuated by a worm 
winch operated by a handle in the rear of the machine. The range is sufficient

to enable the transport wheels to be adjusted without other packing. The 
driving-gear is simple, the cross shafts driven from the first motion shaft by 
two pairs of bevel gear leads forward to drive the knife and binder, and to the 
rear to drive the apron-elevator and reel. The arrangements for disconnect- 
ing the knife are very simple and efficient. The binder is of the Appleby 
class and has all its motions positive, depending on cam action and not on 
springs ; the plunger-bolt has an adjustment to compensate for the wear of the 
gripper disc. There are two trips ; one operated by a loose section of the deck, 
and the other by the fork against which the sheaf is packed (Fig. 18). The
