PROVISIONAL SPECIFICATION.
Improved Nozzle and Delivery-board suitable for Pneumatic Machines
for Distributing Seeds, Manures, and other Solid or Liquid
Substances over Land under Cultivation.
1 GEORGE FREDERICK STRAWSON of Newbury in the County of Berks Chemical
Manure Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention is an improvement on the nozzle and delivery board described in
the Specification of my previous Letters Patent No. 1615 dated 3rd February 1888.
The object of this invention is to insure the material being more equally distributed
over the surface of the land or crop undor treatment (more particularly when the
machine is travelling over sidelong ground) than is obtainable by the nozzles I have
employed up to the present time.
According to this invention I make the delivery nozzle flattened at the outer end
and may be of a smaller area in the centre than at the sides so as to allow a freer
escape of air sideways and the delivery board I provide with a number of division
pieces across it in the direction of the air current which division pieces or partitions
may reach up to the feed roller or may be made in two or more pieces the lower
portion of which is attached to the delivery hoard and the upper portion to a scraper
or otherwise fixed to the apparatus to allow of the adjustment of the delivery board
thus splitting up the feed and preventing it from falling to one side when one wheel
of the machine runs on higher ground than the other and ensuring more equal
distribution of the material over the land or crops.
Dated the 28th day of January 1889.

COMPLETE SPECIFICATION.
Improved Nozzle and Delivery-board suitable for Pneumatic Machines
for Distributing Seeds, Manures, and other Solid or Liquid
Substances over Land under Cultivation.
I GEORGE FREDERICK STRAWSON of Newbury, in the County of Berks, Chemical
Manure Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
This Invention is an improvement on the nozzle and delivery board described in
the Specification of my previous Letters Patent No. 1615 dated 3rd February 1888.
The object of this Invention is to ensure the material being more equally distributed
over the surface of the Land or crop under treatment (more particularly when the
Machine is travelling over sidelong ground) than is attainable by the nozzles 1 have
employed up to the present time.
According to this Invention I make the delivery nozzle flattened at the outer end
and preferably of smaller area in the centre than at the sides as shewn in Figures 1. 2.
and 3 of the accompanying drawing so as to allow a freer escape of air sideways
and the delivery board I provide with a number of division pieces across it in the
direction of the air current as shewn in Figure 4 which division pieces may reach up
to the feed rollers or may be made in two or more pieces as shewn in Figure 5
where a represents the delivery nozzle 6 61 feed rollers c delivery board d upper
portion of division pieces e the lower portion of same which is attached to the delivery
board c and the portion d to a scraper or otherwise fixed to the apparatus to allow of

page_text: the adjustment of the delivery board thus splitting up the feed and preventing it from
falling to one side when one wheel of the Machine runs on higher ground than
the other and ensuring a more equal distribution of the material over the land
or crop.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
I. The Improved delivery Nozzle shewn in Figures 1. 2 and 3 substantially as
described.
II. The Improved delivery board substantially as described and shewn at Figure 4
of the accompanying drawing.
