An Improved Manure Distributor,
I, PAUL EHMKE, of Neustettin, in the Empire of Germany, Ironfounder and
Machine Maker, 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 the manure spreaders or distributors hitherto employed in addition to endless
chains, scrapers and other like forwarding appliances for spreading the manure,
distributing wheels fitted with spikes or armis have been made use of.
These separate spreading wheels have however the drawbacks of not spreading
the manure evenly, of easily sticking fast in the distributing openings provided
in the manure box owing to the stopping up of said openings, and also that the
said openings do not sufficiently close when the apparatus is stationary or special
closing devices are necessary for that purpose which again cause difficulties and
especially easily cause stoppages. These drawbacks are avoided in the present
manure distributor by the employment of a single distributing roller extending
over the whole width of the manure box, which roller effects a perfectly even
spreading of the manure across the whole width of spreading and lies in a suit-
able slotted opening extending across the whole width of the box in such a way
that when stationary it closes this opening so that separate closing devices are
unnecessary.
In the accompanying drawings,
Figure 1 is a sectional rear view and Figure 2 a cross section of the manure
box and spreading roller. As shown, a distributing roller extending over the
entire width of the manure box a is arranged in a suitably wide slotted opening c
in the rear wall m of the box directly under the rear wall and closely over the
bottom. The under edge of the rear wall, which edge forms the upper border of
the distributing slot of the box is extended by a cover board & attached thereto,
which in the drawing is shown for instance on the outer side of the rear wall and
is covered with a wind protecting shield e, but may equally well be placed on the
inner side. In consequence of this arrangement the distributing roller when
stationary regardless of the position it then stands in, always tightly closes with
its scoops or scrapers the slotted opening c of the box, so that no manure can fall
out of the box. The distributing roller thus itself secures the closing of the box
when the manure spreader is not in use, and any further closing devices are dis-
pensed with. In the interior of the box a slide board is arranged on the rear
rear wall m over the roller b which prevents the formation of cavities in the
material to be spread. Over this slide board, a siever is provided which is in-
serted through a slit s in the rear wall, and prevents larger foreign bodies con-
tained in the manure from reaching the roller and damaging the same.
This improved manure spreader is thus characterised by great simplicity which
is of great importance in such machines, so that any ordinary agricultural

of the distributing box a and scoop or scraper roller b which may be removed from
the box in the easiest possible manner by merely unfastening two covers or caps

case of necessity may be easily and thoroughly cleaned.
The parts of the manure distributor which come in contact with the manure
are made without metal parts, as metal is strongly acted on by artificial manure,
which sets thereon in such a way that the good working of the machine is affected
and gradually destroyed. The spreading box a is made of wood impregnated with
carbolineum, (a product of the distillation of coal tar known under this name in
Germany) and the distributing roller of wood bars f, between which strips of
rubber, leather or other suitable elastic material not attacked by the manure are
longitudinally stretched as scrapers or scoops, and which are not liable to break
owing to their flexibility. These scoops are provided in the middle with a rib
which engages in a groove formed in the wood bar and thereby holds the scoop
immovably and everywhere projecting evenly outwards. When the outer edge
of the scraper or scoop is worn away it can be reversed and thus used on the other
side so that great durability of said scoops is attained.
The spreading roller is rotated in the ordinary manner by gearing from one
wheel of the manure spreader, and this gearing is so arranged that by means of
change wheels the roller may be revolved faster or slower and correspondingly
more or less manure distributed. If the machine be moved forward in the direc-
tion indicated by the straight arrow the spreading roller will revolve in the direc-
tion indicated by the curved arrow and distribute the manure.
Holes are pro-
rided in the bottom of the box close to the rear and the manure falls out of the
apparatus partly through these holes and partly over the rear bottom edge. By
this means a good distribution of the manure more particularly when it is some-
what moist and thus forms strips, is obtained.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is: :-
A manure spreader having a single distributing roller (c) provided with scrapers
or scoops and extending over the whole width of the box, said roller being arranged
in the distributing opening or slot (c) of the box (a) in such a way that when
stationary it closes the distributing slot tightly above and below in any position
and the scrapers or scoops (9) of the roller being made of elastic material to pre-
vent their being broken off, substantially as herein before described.
