COMPLETE SPECIFICATION.
Improvements in and relating to Grain Shoots.
I, CARL MORADELLI, Foreman of Baumstrasse 2, Munich in the Kingdom of
Bavaria, German Empire, do hereby declare the nature of my invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
The present invention relates to a device by means of which the quantity of grain
passed along a grain shoot may be varied at will. The regulating device is
arranged underneath the hoppers of the upper floors of grain stores and at the
bottom of the bin at the lower floor, from which bin the grain may be taken at any
desired rate, according to the adjustment of the said device.
The device consists of a series of angle irons arranged transversely over the
bottom of the bin at a certain distance from each other, said angles being
vertically adjustable at will. Between the said angles and below the same are
mounted a number of adjustable segments, which may be moved to allow a greater
or less space between themselves and the said angles. According to the adjustment
of the segments, the grain may be allowed to pass between them and the angles in
greater or less quantities.
And in order to make this Specification more easily intelligible reference is had
to the accompanying drawing in which similar letters denote similar parts
throughout the several views:
Fig. 1 being a vertical section of the device,
Fig. 2 a horizontal section on line in Fig. 1, and
Fig. 3 a vertical transverse section on line y y in Fig. 1.
On the frame a b at the bottom of the box or bin A are mounted the inverted
transverse angle irons cc by means of screws d d, which serve also to adjust the
said angles vertically, the said screws resting on and terminating in the lateral
frame parts a a (Fig. 3). Between each two angles is arranged a curved plate g,
mounted at each end on segments / h, to which are attached at one and the same
end of each plate the bars ii said bars being each pivoted to a bar or angle iron k,
fixed at the lower part of the framing a b. The bars ii extend below the
stationary bark and are each pivoted at their lower end to a moveable connecting
rod m, having at its end an operating lever n. The segments at the further ends
of the plates are supported on short arms, pivotally attached at h' to the further
side of the frame.
By altering the position of the rod n and with it the positions of the plates g
with regard to the angles c, the spaces f between the said angles and plates may
be varied and thus the outflow of the grain from the bin increased or diminished
at will. Any suitable means may be provided to retain the bar m in the desired
position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is performed I declare that what I claim is :-
The combination of a framing a bat the bottom of a bin or hopper, transverse
inverted angles c, vertically adjustable on said frame by means of screws d d,
transverse curved plates g. beneath and between said angles, segments at each end

wardly extending arms ii, connecting rod to which said arms are pivoted at
their lower end and means for operating the said rod substantially as described.
