Improvements in Apparatus for Distributing Seeds, Sand, and like
Granular or Pulverulent Substances.
We, JAMES AUCHINACHIE and JOHN SIMPSON, Agricultural Implement and
Machine Makers, Keith, in the County of Banff, do hereby declare the nature of
this invention to be as follows:-
This invention has for its object the provision of simple and improved apparatus
for distributing seeds, ground lime, artificial manure and similar granular or
pulverulent substances on to land or for discharging sand on to streets.
The improved machine is of the class in which a seed box or trough is fitted on a
wheeled framing so as to extend across it and parallel to the running wheel axle.
Within this box is fitted a square or like shaft or as is preferred two such shafts or
lengths of shafting placed in line and carried in bush bearings at the ends and at
the middle of the framing where the ends of the shafts meet. On the shaft or on
each length of shafting a boss carrying a screw or screw blades is fitted and at
either end of the screw is a toothed pinion the screws and pinions being of such a
diameter as to fit the bottom part of the seed box or trough, or a number of such
screw sections and pinions may be fitted on the shaft which as well as the box
may be of any desired length. The shafts are driven from the travelling wheels
carrying the framing which wheels are fitted to run loose but by means of a
ratchet and catch or like device may be put into gear to drive the shaft or shafts
in the seed box. By the rotation of the shaft or shafts the screws feed forward
the seeds or other substances towards the pinions which serve to facilitate their
discharge through holes or other outlets formed in the box in proximity to said
pinions.

page_text: 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 has for its object the provision of simple and improved apparatus
for distributing seeds, ground lime, artificial manure and similar granular or
pulverulent substances on to land or for discharging sand on to streets.
The invention is illustrated by the accompanying drawings, Figure 1 being a
plan and Figure 2 a transverse vertical section of the improved apparatus.
Figure 3 is an enlarged view of the feeding screw used in the seed box or trough.
The improved machine is of the class in which a seed box or trough A is
fitted on a wheeled framing B so as to extend across it and parallel to the run-
ning wheel axle C. Within this box A is fitted a square or like shaft or as is
preferred two such shafts D, D', or lengths of shafting placed in line and carried
in bush bearings E at the ends and at the middle of the framing where the ends
of the shafts meet. On the shaft or on each length D, D', of shafting, a boss
carrying a screw or screw blades is fitted and at either end of the screw is a
toothed pinion the screws and pinions being of such a diameter as to fit the
bottom part of the seed box or trough, or a number of such right and left hand
screw sections F and pinions G may be fitted on the shafts D, D¹, which as well
as the box A may be of any desired length, the screws being arranged to gather
the seed and direct it towards the outlets K formed in the box through which it
is forced by means of the pinions which are situated in proximity to the outlets.
The shafts D, D¹, are driven from the travelling wheels H carrying the framing B
which wheels H are fitted to run loose but by means of a ratchet and catch
or pinions or chain may be used for altering speed of the shafts D, D¹, in the
seed box, or like devices may be put into gear to drive the shaft or shafts D), D',
in the seed box A.
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:-
The improved apparatus for distributing seeds, sand and like granular sub-
stances, comprising a box or trough for the reception of the substance to be
distributed, and a shaft or shafts carried in said box or trough and provided with
a series of right and left handed sectional screw blades and pinions for the púr-
pose of feeding the material to and discharging it through a series of holes in
the bottom plate of the box or trough substantially as described.
