PROVISIONAL SPECIFICATION.
Drill Manure Spreading Machine.
I, JAMES THOMSON, of Mains of Skeith, Deskford, Cullen in the County of
Banff, North Britain, Farmer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to a Drill Manure Spreading Machine, and has for its object
to construct a machine which will spread the dung in the drills after it has been
thrown on the ground from the carts in forkfuls, in a simple and efficient manner.
In carrying out my said invention, I provide a suitable frame having the necessary
driving wheels, shafts and means for carrying the working parts of the machine,
as also an operators seat.
Underneath this frame and in front of the driving
wheels axle mount a horizontal shaft having two or more, though preferably
three, cranks to each of which are attached vertically standing prongs, the upper
ends of which are attached to a cross bar or frame by means of double joints, so
as to permit of a winch like motion being given to said prongs.
The crank shaft is carried in slot bearings, and is driven from the main driving
wheels by means of a pitch chain and pulleys, or other gearing in such a manner
as to drive the crank shaft in an opposite direction to that of the driving wheels
(which are so made as to run on the tops of the drills,) so as to give the prongs a
forward motion and so cause said prongs to catch the forkfuls of dung, shake them
up and then spread them out along the drill.
In front of said vertical prongs I mount two or more suitably shaped guards
which clear the dung off the top of the drills and push it towards the prongs. The
dung after being pulverized by the prongs passes through between two or more
suitably shaped sheet iron or other plates or guides, preferably mounted adjustably,
which keeps the dung in the centre of the drills.
The crank shaft, which is provided between the cranks with two or more curved
spikes which roll the dung forward and so keep it clear of the cranks, as well as
the other working parts are mounted in such a manner and connected by suitable
means to an operating lever or handle mounted above the main frame in such a
manner as to enable the operator or driver to regulate the depth of the prongs as
well to raise them up when out of the drill.

COMPLETE SPECIFICATION.
Drill Manure Spreading Machine.
I, JAMES THOMSON, of Mains of Skeith, Deskford, Cullen, in the County of
Banff, North Britain, Farmer, 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 relates to a Drill Manure Spreading Machine, and has for its object
to construct a machine which will break and spread farm yard manure in the drills
after it has been thrown on the grounds from the carts in forkfuls in a simple and
efficient manner.
Figure 1 of the accompanying drawings is an elevation and Figure 2 a plan.

In carrying out my said invention I provide a suitable frame M having the
necessary driving wheels A (preferably concave as shown) shaft or axle B and
means for carrying the working parts of the machine as also an operator's seat.
Underneath this frame M and in front of the driving wheels axle B I mount a
horizontal shaft F having two or more, though preferably three, cranks to each of
which are attached vertically standing prongs G the upper ends of which are
attached to a cross bar or frame N by means of double joints or links I so as to
permit of a winch like or reciprocating motion being given to said prongs.
The crank shaft F is carried in bearings working in the slots F₁ of the frame N
and is driven from the main driving wheels A by means of a spur wheel C, which
drives a combined chain wheel and pinion D, which with a pitch chain conveys the
motion to the small chain wheel E on the crank shaft F driving the said shaft in
an opposite direction to that of the driving wheels A, which are so made as to run
on the tops of the drills, so as to give the prongs G a forward motion and so cause
the said prongs G to catch the forkfuls of manure, shake them up and then spread
them out along the drill.
The crank shaft F is provided between the cranks with two or more curved
guards or prongs H which roll the manure forward and so keep it clear of the
crank shaft F, as well as the other working parts. The crank shaft F with the
prongs G and guards H are mounted in such a manner and connected by suitable
means to an operating lever and handle J, mounted above the main frame M, in
such a manner, as to enable the operator or driver to regulate the depth of the
prongs G, as well as raise them up when out of the drill. The regulating lever
and handle J is kept in position by the quadrant K or other suitable means.
quadrant is fixed to a double stay O which is attached between the main frame M
and the top of frame N.
This
In front of the main frame M the draught shafts L are attached, to which are
fixed the prongs P which carry the front parts of the guiding plates P₁ which are
preferably adjustable to suit the depth of the drills, the plates P' are fixed at the
back and at the bottom of the slot F' in frame N, these prongs P and plates P¹
are suitably shaped to clear the manure off the top of the drills, and guide it
towards the prongs G, to be broken and spread, keeping it at the same time in the
centre of the furrow.
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 :-
1st. The general arrangement, construction and combination of the various parts
constituting the drill manure spreading machine, substantially as, and for the
purposes herein before described and shown in the accompanying drawings.
2nd. In drill manure spreading machines, the breaking and spreading prongs G, H,
prongs P and plates P' and their connections or the mechanical equivalent of same,
substantially as hereinbefore described and shown in the accompanying drawings.
