PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Distributing Seeds, Manures,
and other Substances.
We; JAMES HORNSBY and JOHN INNOCENT both of Spittlegate Iron Works
Grantham, in the County of Lincoln Engineers, do hereby declare the nature of
this invention to be as follows :-
Great difficulty is often experienced in providing a constant supply of the material
(especially if it is damp and sticky) to the delivery roll or rolls at the bottom of the
hopper.
According to this invention we provide a stirrer in the hopper which is supported
and driven from the top only so that the mouth at the bottom of the hopper is not
obstructed by any bearing. We also make the stirrer of a cork-screw shape, so that
its rotation prevents the material from sticking to the sides of the hopper leaving the
central cylinder or cone of material unsupported except by the delivery roll or rolls,
sometimes we make the hopper to revolve and the stirrer fixed. The delivery roll we
form with longitudinal ribs or channels and provide a spring scraper by which the
material which has collected in the channels is scraped off.
For driving the various parts of the machine we mount a spur wheel on the axle of
the main carrying wheel. This spur wheel gears with a pinion made fast to another
spur wheel mounted on a separate spindle. The latter spur wheel drives a pinion and
a pulley mounted loosely on the axis of the main wheel a belt from the pulley drives
the fan. The feed roll at the mouth of the hopper may be driven from the main axle
by a chain or belt.

We, JAMES HORNSBY and JOHN INNOCENT, both of Spittlegate Iron Works,
Grantham, in the County of Lincoln, Engineers, 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 :-

The form of the stirrer X shown in Figure 3 is that which we prefer but it may be
varied in many ways, thus the lower part may be of a conical cork-screw form or the
central axis may be carried down nearly to the bottom of the hopper and carry
several arms or stirrers.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
"
1. The combination of a hopper and a stirrer supported and driven from the top
only.
:
2. The combination of a hopper and a stirrer supported and driven from the
top only and so formed that it lies close to the internal surface of the hopper.
3. The combination of a rotating hopper and a stirrer supported from the top only.
4. The combination of a rotating hopper and a stirrer supported from the top only
and so formed that it lies close to the internal surface of the hopper,

page_text: 5. Driving the fan from a wheel loose upon the main shaft and driven from
the main shaft through gearing on an intermediate shaft substantially as described.
6. Apparatus for distributing seeds, manures and other substances substantially as
described and shown in the drawings.
