A Pneumatic
Solid or Liquid Substances over Land under Cultivation.
I GEORGE FREDERICK STRAWSON Newbury, Berkshire Chemical Manure Manu-
facturer do hereby declare the nature of this invention to be as follows:-
To distribute broad cast for agricultural and other purposes, all kinds of corn, seed
artificial manures, chemicals, remedies for the Turnip Fly, and all substances either in
a solid or liquid form that are required to be distributed regularly over the surface of
land under cultivation by the means of air-pressure, obtained by a centrifugal fan or
other air-pressure machine, mounted on wheels which give the first motion and
The materials to be distributed are carried upon
multiplied by gearing or otherwise.

A Pneumatic Machine for Distributing Seeds, Manures, and other
Solid or Liquid Substances over Land under Cultivation.
[ GEORGE FREDERICK STRAWSON of Newbury in the County of Berkshire Chemical
Manure Manufacturer, do hereby declare the nature of this invention for AN IMPROVED
PNEUMATIC MACHINE and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The object of this invention is to provide an apparatus whereby all kinds of corn
seed artificial manures chemicals, remedies for Turnip Fly or other insect pests and
other substances in a liquid or solid form that are required to be deposited on the
surface of land or crops under cultivation may be distributed regularly and evenly
over the surface of such land or crops at a small cost. According to this invention I
carry the material to be distributed in a hopper connected with a fan or blower and
admit more or less material to the action of the air current produced by such fan or
blower by means of a suitable feeding device so as to distribute a greater or less
quantity of material per acre as required.
I drive the fan or blower by suitable -gearing from the travelling wheels on which
the whole of the apparatus is mounted.
In the accompanying drawings Figure 1 shews a side elevation of an apparatus
constructed according to my invention part of the travelling wheels being removed to
shew the gearing. Figure 2 section of hopper and fan shewing feeding rollers.
Figure 3 delivery board. Figures 4 and 5 distributing nozzle for solid substances such
as seeds corn soot or the like. Figure 6 delivery nozzle for liquids. Figure 7 section
of same. Figures 8 and 9 modifications of the same for special purposes. The same
letters denote the same parts in all the figures.
a is a hopper attached to the frame carried by the travelling wheels c upon the
axle of the wheel c is keyed a spur wheel d gearing with the pinion e said pinion
driving the spur wheel which in turn drives the pinion g to the axle of which
is keyed the belt pulley h which drives the fan ; by means of the pulley i and
belt k. The feeding rollers are driven from the travelling axle by means of
a pitch chain and pulley m the pulley m being keyed to the axle of one of the
rollers the other end of the said axle has a spur wheel keyed thereto gearing
with another spur wheel keyed to the axle of the other roller or other suitable
means. The material to be distributed falls from the hopper a on to the portion
of the nozzle which spreads the stream of material into the desired form namely
rather thicker at the sides than at the centre. and the current of air carries the
material with it being guided in its course by the inclined delivery board n the
said board being capable of adjustment to any desired angle vertically by means
of the clamp and hinge t. 2 is a wind guard (only required in windy weather)
also capable of vertical adjustment by the chain by means of these adjustments the
apparatus is enabled to distribute materials of different specific gravities or degrees of

outwards or away from each other at their upper side. is a stay rod to support
the hopper a.
When it is desired to distribute liquids the nozzle wind guard p and delivery
board n are removed and the nozzle a (Figures 6 and 7) substituted therefor and
connected by means of a suitable pipe to the cock z on the hopper a in which and in
communication with the said cock is inserted a loose tank made of galvanised iron or
other suitable material.
The liquid runs down the pipe and enters the receptacle through the orifice e
which orifice is fitted with a nipple F to attach the connecting pipe to the nozzle A.
From B lead small tubes contracted at their outer ends the liquid flows down these
tubes and is taken up by the annular air currents passing round them and dispersed
from the openings D in the form of a very fine spray over the land or crops. The
portion G of the nozzle fits the outlet pipe of the fan. Figures 8 and 9 show a
modification of the last mentioned nozzle."
I also fit the apparatus with ordinary belt striking gear or clutches to enable the
operator to stop the air blast and feeding device when desired without stopping the
travelling wheels.
In conclusion I would remark that I do not intend to limit myself to the precise
details of gearing or feeding device herein described and shewn in the drawings
but I may drive the fan by means of any suitable gearing friction wheels for
example.
Having now particularly described and ascertained the nature of my said
invention I declare that what I claim is
1. The improved general arrangement and construction of a pneumatic machine for
distributing seeds artificial manures and other solid or liquid substances over land or
crops under cultivation substantially as described and shewn by the accompanying
sheets of drawings and operating as specified.
2. In a pneumatic machine for distributing seeds artificial manures and other solid
substances over land or crops under cultivation the delivery nozzle substantially as
described and shewn at Figures 4 and 5 of the accompanying drawings.
3. In a pneumatic machine for distributing liquids over land or crops under
cultivation the delivery nozzle A for distributing liquids substantially as described and
shewn at Figures 6 and 7 of the accompanying drawings.
4. In a pneumatic machine for distributing liquids over land or crops under
cultivation the modification of the above shown at. Figures 8 and 9.
Dated this 20th day of October 1888.
