PROVISIONAL SPECIFICATION.
"Improvements in Machinery for Distributing or Sowing Artificial
Manures"
We, ROBERT WALLACE, and WILLIAM WALLACE, of Whitletts, near Ayr, in, the
County of Ayr, North Britain, Agricultural Implement Makers, do hereby declare
the nature of this invention to be as follows, that is to say :-
:-
The said invention has for its object to improve the construction and action of
machinery for distributing or sowing artificial manures and relates more particularly
to machines of the kind described in Patent Specification No. 24830 of 1893 whereby
such machines instead of sowing artificial manures in drills only are made capable of
distributing the manure broadcast..
In the machine hereinbefore referred to a pair of disks revolve between the bottom
of a hopper and a flat piece or table and move the manure dropping from the hopper
into delivery shoots and according to the present invention the manure drops from
the lower end of each shoot on to the upper side of a disk. Each disk is made with
a number of ribs or vanes on its upper side these ribs having, by preference, small
deviations from radii. The disks are carried by and pivoted on a bracket attached to
the framing and have each a small bevil pinion on its upper surface which gears with
a bevil wheel on a shaft carried in bearings in the framing. A clutch on one end of
this shaft engages with a sprocket wheel which receives motion through a pitch chain
from a similar wheel on the main axle of the machine. By these means when the
machine is in motion the disks are made to revolve at a comparatively high speed in
opposite directions and the ribs or vanes so direct the manure falling on to the upper
surface of the disks that it is distributed broadcast over the field. In the event of
the machine being brought suddenly to a stop the clutch slips and this allows the
parts to come to rest gradually and thus prevent the breakage of any part.

COMPLETE SPECIFICATION (AMENDED).
Improvements in Machinery for Distributing or Sowing Artificial
Manures"

page_text: of Ayr, North Britain, Agricultural Implement Makers, 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 :-that is to say :-
The said invention has for its object to improve the construction and action of
machinery for distributing or sowing artificial manures and relates more particularly
to machines of the kind described in Patent Specification No 24830 of 1893 whereby
such machines instead of sowing artificial manures in drills only are made capable of
distributing the manure broadcast.
In carrying out our present invention we combine with the machine bereinbefore
referred to a pair of disks on to which the manure drops from the lower ends of
delivery shoots. Each disk is made with a number of ribs or vanes on its upper
surface some of which have small deviations from radii or do not converge towards a
common centre and is so driven that when the machine is in motion the disks are
made to revolve at a comparatively high speed in opposite directions, and the ribs or
vanes so direct the manure falling on to them that it is distributed broadcast over
the field.
•
And in order that our said invention and the manner of performing the same may
be properly understood, we hereunto append a sheet of explanatory drawings, to be
hereinafter referred to, and showing our improvements.
Figure, 1, on the accompanying sheet of drawings is a plan, Figure, 2, a side
elevation, and Figure, 3, a front elevation, showing a machine for distributing or
sowing artificial manures, as made with our present improvements. Figure, 4, is a
plan, drawn to a larger scale, showing one of the distributing disks,
In these drawings, the same reference letters are used to mark the same or like
parts wherever they are repeated.
In the machine herein before referred to and shown on the accompanying drawings,
a pair of disks revolve between the bottom of a hopper, A, and a flat piece or table
and move the manure dropping from the hopper into delivery shoots, B, and, according
to the present invention, the manure drops from the lower end of each shoot, B, on
to the upper side of a disk, C. Each disk, C, is made with a number of ribs or vanes,
D), fixed on its upper side, some of these having, by-preference; as shown, small
deviations from radii. The disks, C, are carried by and pivoted on a bracket, E,
attached to the framing and each has a small bevil pinion, F, on its upper surface
which gears with a bevil wheel, G, on a shaft, H, carried in bearings in the framing.
A ratchet-toothed clutch, J, arranged to drive in one direction only, on the shaft, H,
engages with the centre of a sprocket wheel, K, being kept in gear by a spring, P, on
the shaft, the sprocket wheel, K, receiving motion through a pitch chain, L, from
a similar wheel, M, on the main axle, N, of the machine, By these means, when the
machine is in motion, the disks, C, are made to revolve at a comparatively high speed
in opposite directions and the ribs or vanes, D, so direct the manure falling on to the
upper surface of the disks, C, that it is distributed broadcast over the field. In the
event of the machine being brought suddenly to a stop, the clutch, J, slips, and this
allows the parts to come to rest gradually, and thus prevent the breakage of any part.
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 :-
-
In machinery for distributing or sowing artificial manures, the combination and
arrangement with the ordinary parts of such machines, of disks held beneath delivery
shoots, the disks being made with a number of ribs or vanes, on their upper surfaces,
some of which have small deviations from radii or do not converge towards a common
centre and being driven by gearing from the main axle of the machine, substantially
as, and for the purposes, herein before described.
