Improvements in Manure Distributing Machines.
I, JOHANN ERNST AUGUST FISCHER, of Rostock in the Empire of Germany,
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:-
In manure distributing machines hitherto used the material was dropped from the
hopper or reservoir on to the ground through a narrow slot provided in an endless
cloth-apron or other device answering the same purpose. This arrangement is
attended by the drawback that in the case of semi-liquid .manure it in the first
place adheres to the cloth and by gradually drying thereon, makes it stiff and
breakable; at the same time it tends to obstruct the discharge slot so that eventually
the machine becomes entirely unfit for use. The attempts hitherto made to remedy
these inconveniences have failed to produce the results sought to be attained for
even to the present time it may be observed in fields manured by machinery that
some places along the line travelled over by the machine are unprovided with
manure. This failure may be mainly accounted for by the insufficient attention
bestowed on the cleaning of the discharge slot, a point which ought, on the contrary,
to be most carefully attended to seeing its great importance.
Moreover the rapid wear of the cloth is another deficiency for which allowance
should be made in the old machines.
To obviate those various drawbacks the cloth apron according to this invention
is replaced by a number of endless chains connected by sheets of wire gauze and
adapted to keep the discharge slot clear by automatic action.
In the accompanying drawings is represented a machine constructed according to
this principle.
Fig. 1 is a front elevation of the machine.
Fig. 2 is a side view, and Fig. 3 a plan of the same.
Figs. 4 and 5 show respectively in clevation and in plan one of the manure-
spreading chains with its wheels or rollers and a portion of the wire-gauze
(Fig. 5).
The machine mainly consists of a hopper or reservoir a mounted upon a portable
frame and having vertical walls, the front and rear walls being provided with slots b
and e extending right across each. The slot b is arranged to be closed or covered
when required by means of a door or valve d. Near the front and rear walls of
the hopper are arranged four shafts carrying pitch wheels g on which work
pitch chains and the various chains are mutually connected by wire gauze or
netting running directly above the bottom of the hopper and carrying along
with it the manure contained therein. The chain wheels are operated by means
of preferably two independent sets of gearing, one at each end of the machine.
i
In addition to the advantages mentioned above an important distinctive feature
of the machine is that owing to the arrangement of four shafts and double
operating mechanism, one half of the machine only may be set in operation at a
time, which is a welcome facility where the piece of ground to be manured is
narrower than the machine. Besides by dividing the hopper two different kinds of
manure may be strewn at a time if necessary.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A manure distributing machine consisting essentially of a manure reservoir or
houver such as a having vertical walls through which honer an arranood

to carry the manure along with them substantially as and for the purpose described
and illustrated in the accompanying drawings.
2. In a manure distributing machine the combination with a reservoir or hopper a
of two independent sets of wire-net-carrying pitch chains each set provided with
its own operating gearing substantially as described and illustrated in the accom-
panying drawings.
3. The combination and arrangement of parts constituting the complete manure-
distributing machine substantially as described and illustrated in the accompanying
drawings.
