Improvements in Machines for Distributing Fertilising Agents.
We, LUDWIG FEHRMANN, of Regenwalde, and JULIUS KLUG, of Gross Radow,
both in the Kingdom of Prussia and Empire of Germany, Manufacturers, 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:
A machine constructed in accordance with this invention and principally intended
for sowing artificial manure comprises a series of toothed wheels gearing with one
another and adapted to pulverize or break up the lumps into which the comminuted
manure may have become consolidated, as well as to throw out or sow the manure thus
crushed and broken up. Means are, moreover, provided whereby the quantity of
manure thus thrown out or sown within a given time or over a given area may be
regulated at will.
In the accompanying drawings, Fig. 1 represents in longitudinal section, Fig. 2 in
plan and Fig. 3 in cross section part of a machine constructed according to the present
improvements. Figs. 4 and 5 shew in elevation the respective ends of the body of
the machine. Figs. 6 and 7 illustrate details employed in regulating the quantity of
manure sown.
The body a of the machine is formed with converging sides and is provided at the
top with a suitable lid or lids b. Slots q are left between the converging sides and
the bottom c. The latter carries a series of bearings for the shafts g of the toothed
wheels h. These wheels gear with each other and serve both to break up and to sow
the manure contained within the body a. Each toothed wheel is preferably actuated
from a longitudinal shaft o by means of bevel-pinions o' o". The shaft o is rotated
from the driving wheel i (this being one of the wheels upon which the machine is
mounted) through the gearing k l m n. The adhesion of the manure to the toothed
wheels is prevented by the said wheels gearing with each other, thereby tending to
keep one another clean.
In order that the quantity of manure sown or thrown out from the machine by the
toothed wheels h may be regulated according to particular requirements, means are
provided for enabling the width of the slots g to be varied at will. Such means
comprise a hand-lever's mounted on a shaft s¹. "The latter carries a pinion & engaging

page_text: with a rack on the sliding rod w; the latter being arranged longitudinally in one of
the converging sides of the body a. A similar sliding rod w¹ is provided on the
opposite side of the machine. The two rods w and w¹ are united by a pivotted levere ;
the motion communicated to the rod w, through the instrumentality of the hand-levers,
being thereby imparted to the rod w¹, the two rods moving in opposite directions.
These rods are formed or provided with racks w² engaging with pinions; the latter,
in turn, gear in the manner shewn in Fig. 2 with racks y attached to slides r mounted
in or forming part of the converging sides of the body a. By these means, the slides?
may be simultaneously caused to approach towards or to recede from the toothed
wheels ; the slots q being varied in width accordingly and the amount of manure
sown or delivered being consequently under control. Springs, such as ¹ (Fig. 6), are
provided for pressing down the slides towards the bottom c of the machine.
For throwing the machine into and out of action, a hand-lever (Fig. 5), fitted
with a catch ¹, is attached to the cover 2 in which the gears k l m are mounted. By
moving the handle z, the cover 2 may be caused to rotate about the shaft and the
pinion m and toothed wheel n thrown into or out of gear as the case may be.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, we claim :-
:-
1. The improved construction of machine for distributing fertilising agents, arranged
and operating substantially as herein described.
2. In a manure-distributing machine, the employment of a manure receptacle
furnished with a moveable floor or bottom consisting of the spur-wheels hh geared
together and arranged to discharge the manure in a horizontal direction through
adjustable slots gq formed between the sides and bottom of the receptacle.
3. Regulating the width of the slots on either side of the receptacle by means
of a hand-levers which works two linked sliding rods w and w¹ in opposite directions,
said rods actuating simultaneously, through suitable rack and pinion mechanism, the
slides whereby the width of the slots 9 9 may be varied as desired.
