platform ; it can be set to any angle, and serves to prevent the 
corn being pushed too far to the rear. In front of this is a 
canvas screen suspended from an arm hinged immediately 
under the driver’s seat and to the underside of his footboard. 
It can be set to any position, and also serves to regulate the 
arrangement of the corn. 
The grain-wheel rises and falls in a slotted bracket, and 
revolves on a stud which is fixed in a sliding-block, actuated by 
a scroll or cylindrical spiral, which engages into the teeth 
formed on the bracket. The handle actuating the spiral 
projects conveniently towards the rear of the platform. 
The divider is secured to the steel framing in a substantial 
manner, and is fitted with a supplementary one for use in long 
and tangled corn ; the latter can be very readily shipped or 
removed, as it is held by only a single bolt. 
The reel is carried by a hollow iron pillar about 1^ in. 
diameter and about 5 ft. high. Its lower end is hinged to the 
front of the gearing frame a little above the platform, and has 
sliding on it a bracket which carries the horizontal reel-spindle, 
which crosses the pillar a little to its rear. On the near side 
this spindle carries a bevel wheel which is geared into by a 
pinion sliding on a light square shaft which lies parallel to and 
close to the pillar, and which in its lower end is connected by a 
universal joint to a bevel wheel which is actuated by an inclined 
rectangular shaft which is driven at its upper end by means 
of bevil gear, in common with the buttor, by the special reel 
driving-shaft already mentioned. 
The sliding bracket carrying the reel is supported by a 
forked lever the fulcrum of which is a rocking-pillar hinged at 
its lower extremity to the front end of the driver’s footboard, 
and is held in position by a notched quadrant into which 
engages a pawl attached to a bar which is connected by a 
pin to the hand lever. The rocking-pillar has a slot in its 
upper end so that when the lever is pulled up the pawl is 
lifted and the pillar can be rocked in the fore-and-aft direction 
so as to bring the reel farther from or nearer to the crop. The 
lever extends backwards to the driver’s seat, and is fitted 
with a spring catch which actuates a pin which may enter any 
one of a series of holes in the pillar, so that by means of one 
and the same lever the reel can be set for height or for 
position. 
The pitman actuating the knife is made of white ash, and 
works, unbushed with metal, on a crank pin 1J- in. diameter, 
and is said to wear very well. 
The buttor on the forward end of the binding-platform is
