The driving-wheel of large size is indicated by the dotted lines at A. The 
first motion shaft B is driven by spur-gearing ; a bevel-wheel on this shaft 
drives from either side the crank-shaft C, and the elevator driving-shaft D. 
The two pinions balance each other, and as the binding machinery is driven 
from D, it will be seen that the arrangements for producing complicated effects 
are remarkably simple. The rollers which drive the apron and elevator by 
which the corn is carried from the knife to the tying-apparatus are both driven 
from the end of the shaft D by chain-gearing. This, again, is well con- 
trived. The a])ron with wooden slots is shown at I, and the elevator-belts at 
J J' J'' J' J* ; and this completes the whole of the machinery belonging to 
the harvester proper. The tying-apparatus can be readily detached and the 
machine worked by manual binders ; all that is required is to shift the driver's 
seat from S to a. Before I proceed to details, it may facilitate my explana- 
tion if I briefly state the plan of working. The corn is delivered in a con- 
tinuous stream on to the concave table Q. The revolving binder-arm, with
