RepoH on the Implements 
and capable of being lengthened by the addition of loose, straight 
pieces about 18 inches long. These branch pipes are arranged 
to swivel round the branches of the breeches pipe by means of 
a handle secured to one of a pair of bevil wheels, fixed to each 
pipe and geared together, so that the two pipes always assume 
symmetrical positions, and can be fixed by a pinching screw in 
any position from the horizontal to the vertical. The object of 
placing the pipes so low is to enable the underside of the lowest 
leaves of the crop to be reached. In the fork of the breeches 
pipe is a valve or hinged partition actuated by a spring catch 
lever directly over it, by means of which the blast can be 
directed at will and to any extent into either branch. The fan 
is driven by a spur wheel, about 20 inches in diameter, keyed 
on to the road-wheels axle gearing into a sliding pinion on a 
second motion shaft, the pinion being capable of shifting in or 
out of gear by means of a spring catch-lever, worked from the 
rear of the machine. The second motion shaft works a third 
motion by means of pitched chains, and this in turn drives the 
fan spindle by the same agency, the ratio of movement between 
the road wheels, and the fan being 42 to 1. 
Over the fan is arranged a sheet-iron hopper for containing 
the material to be distributed. The road-wheels axle passes 
through the bottom of the hopper and carries a spiked roller 
which works in a carriage and through a comb on the front side. 
Underneath is a second spiked roller, revolving twelve times as 
fast as the road wheels, and driven by a pitched chain from the 
second motion shaft. Under the lower roller is a slide actuated 
by a spring catch-lever at the right side of the hopper, by which 
the rate of delivery can be regulated. The hopper is covered 
by a close-fitting hinged lid ; the powder to be distributed 
falls in a uniform shower right across the current of air from 
the fan, the delivery pipe of which is at this point 6 inches wide 
by 4 inches deep, and, mixing intimately with the air, is carried 
out and distributed by the branch pipes. The machine will 
deliver from 20 to 25 feet high, it vveighs 5 cwt., and is easily 
drawn by one horse. The back end of the implement is fitted 
with a trailing wheel, mounted castor fashion, and it will turn 
in the rows in a length of 4 feet G inches. 
The machine is adapted also for liquid distribution by sub- 
stituting a tank for the hopper, fitting it with an adjustable 
outlet, and substituting for the air pipes a series of nipples, 
arranged to suit the particular crop to be treated.
