Improvements in or Connected with Grain Elevators and Analogous
Apparatus for Raising Materials by an Endless Chain of Scoops.
We, FRIEDRICH FRANZ GUSTAV UNRUB and CARL RICHARD LIEBIG, Manufacturers,
of Reudnitz-Leipzig, in the kingdom of Saxony, do hereby declare the nature of our
invention to be as follows:-
Our invention relates more particularly to the scoops which are arranged in an end-
less chain or mounted on an endless band and serve to transport cereals and other
granulous material to a higher level, the object being to economise space and render
the working of the elevator more uniform by placing the consecutive scoops in close
proximity to each other instead of leaving blanks or interstices between the same.
For this purpose the base of each scoop (that is the side nearest to the travelling
band) is curved with a radius approximately equal to that of the (smallest practicable)
elevator pulley and secured to the endless band by screw-bolts or other suitable means;
the rear wall of the scoop forms an acute angle to the base and is provided with a pair of
wings or flanges situated at the back of the rear wall and parallel to the sides of the
scoop, but at such a distance apart, as to fit between the sides of the next following
scoop, or so that the sides of the latter fit between the said flanges. The said scoops
being shaped as described and placed close together, each pair of flanges forms a
guide for the sides of the following scoop, and the discharge of grain is practically
continuous.

Improvements in or Connected with Grain Elevators and Analogous
Apparatus for Raising Materials by an Endless Chain of Scoops.
We, FRIEDRICH FRANZ GUSTAV UNRUH and CARL RICHARD LIEBIG, Manufacturers,
of Reudnitz-Leipzig, in the Kingdom of Saxony, do hereby declare the nature of our
invention and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
Our invention relates more particularly to the scoops which are arranged in an
endless chain or mounted on an endless band and serve to transport coreals and other
granulous material to a higher level, the object being to economise space and to render
the discharge continuous.
In the further description reference will be made to the accompanying drawings, of
which Fig. 1 is partly an elevation and partly a vertical section showing the general
construction and action of an improved elevator, while Fig. 2 shows a scoop on a larger
scale. Fig 3 is an elevation and Fig. 4 a plan of Fig. 2.
As shown, the scoops are placed in close proximity to each other, instead of leaving
blanks between them as usual. The bottom of each scoop is curved with a radius
nearly equal to that of the smallest elevator pulley which can be conveniently used,
and is fixed to the belt at c by means of screws.
The rear wall r is provided with lateral flanges a and forms an acute angle to the
bottom g, h. This rear wall extends underneath the side walls of the following scoop
as shown.
Having now particularly described the nature of our invention, we declare that
we claim :
r
An elevator scoop having a rear wall which forms an acute angle to the curved
bottom g, h, and which is provided with flanges a extending between the side w of the
following scoop.
