Improvements in Apparatus for Spreading Grain over the Floors of
Malt-kilns, Granaries, and like places, and for Removing it
therefrom.
I, GEORGE FREDERICK Redfern, of the firm of G. F. Redfern & Co., the General
Patent Office, No. 4, South Street. Finsbury, in the county of London, Patent Agents,
do hereby declare the nature of this invention (a communication from abroad by
Messieurs Wirth & Co., of Frankfort-on-the-Main, in the Empire of Germany, acting
as Agents for Siegfried Hirschler, of Worms on the Rhine, in the Empire of Germany,
Malister,) to be as follows:-
This invention relates to improvements in the apparatus for removing grain and
other substances from malt-kilns, granaries and like places forming the subject of a
former application for a Patent dated 1st April 1889, No. 5548, the object of the
present invention being to construct the said apparatus so that it will serve to spread
the grain evenly over the floor as well as to clear it therefrom.
The apparatus comprises two endless chains or bands running over chain wheels and
serving to carry the various sized boards or scrapers as in the specification of my
said former application.
According to my present invention I attach angle-iron bars between the chains or
bands at certain distances apart whore the boards or scrapers are to be secured, the said
bars having flat iron projections fixed to them to carry the boards or scrapers which
are hinged thereto and guided by bars or guides which are also attached to the flat
iron projections.
When clearing out the grain or other substance it is necessary to keep the boards
or scrapers rigidly in a vertical position. This I do by means of bars placed between
the guides against which bars the scrapers then bear.
After one storey or floor of the drying house has been cleared and the material
conducted into the next lower storey it is spread out evenly on the floor by a similar
apparatus which is caused to work in an opposite direction to that taken when clearing
the floor. The trap doors are all located on one side and consequently the chain
wheels must revolve in one direction to clear the material out and in the opposite
direction for spreading the material. When running in the direction for spreading
the material the boards or scrapers do not rest on the transverse bars and take a more
or less inclined position according to the resistance of the material to be spread, con-
sequently the scrapers only carry along a small quantity of the material at a time till
it becomes gradually spread evenly all over the floor.
The clearing is afterwards effected by simply reversing the direction of motion of
the chains or bands. To prevent the scrapers from becoming bent they are guided
by rollers or wheels running in channel irons.

0 Improvements in Apparatus for Spreading Grain over the Floors of
Malt-kilns, Granaries, and like places, and for Removing it
therefrom.
I, GEORGE FREDERICK REDFERN, of the firm of G. F. Redfern & Co., the General
Patent Office, No. 4, South Street, Finsbury, in the county of London, Patent Agents,
5 do hereby declare the nature of this invention (a cominunication from abroad by

page_text: Messieurs Wirth & Co., of Frankfort-on-the-Main, in the Empire of Germany,
acting as Agents for Siegfried Hirschler, of Worms on the Rhine, in the Empire of
Germany Maltster,) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to improvements in the apparatus for removing grain and
other substances from malt-kilns, granaries and like places forming the subject of a
former Patent dated 1st April 1889, No. 5548, the object of the present invention
being to construct the said apparatus so that it will serve to spread the grain evenly
over the floor as well as to clear it therefrom.
In the accompanying drawing
Figure 1 is a section of two superposed floors of a malt kiln fitted with my improved
apparatus for spreading grain over the floors and for removing it therefrom.
Figures 2 and 3 are respectively a vertical section and a horizontal section drawn
to an enlarged scale illustrating a portion of my improvements.
Similar letters in all the figures indicate similar parts.
The
apparatus comprises two endless chains or hands running over chain wheels and
serving to carry various sized boards or scrapers as in the Specification of the said
former Patent.
According to my present invention I attach angle-iron bars a between the chains
or bands at certain distances apart where the boards or scrapers are to be secured, the
said bars having flat, iron projections fixed to them to carry the boards or scrapers g
which are hinged thereto at and guided by bars or guides c which are attached to
the angle-iron bars a.
When clearing out the grain or other substance it is necessary to keep the boards
or scrapers rigidly in a vertical position. This I do by means of bars i placed
between the guides c against which bars the scrapers then bear.
After one storey or floor A of the drying house has been cleared and the material
conducted into the next lower storey B it is spread out evenly on the floor by a
similar apparatus which is caused to work in an opposite direction to that taken when
clearing the floor A. The trap doors are all located on one side (the left hand side
for example as shewn in the drawing) and consequently the chain wheels must revolve
in one direction to clear the material out and in the opposite direction for spreading
the material. When running in the direction for spreading the material the boards
or scrapers do not rest on the bars and take a more or less inclined position
according to the resistance of the material to be spread; consequently the scrapers
only carry along a small quantity of the material at a time till it becomes gradually
spread evenly all over the floor.
The clearing is afterwards effected by simply reversing the direction of motion of
the chains or bands. To prevent the scrapers from becoming bent they are guided
by rollers or wheels d running in channel irons e as shewn in the detailed views
Figures 2 and 3.
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 1
claim is :-
(1) The described means of attaching the boards or scrapers of apparatus, such as
that herein referred to, for spreading grain over the floors of malt-kilns, granaries
and like places and for removing it therefrom whereby the said scrapers are caused
to assume a vertical position while removing the grain and an inclined position
varying with the resistance of the material while spreading the same.
(2) The improved apparatus for spreading grain over the floors of malt-kilns,
granaries and like places and for removing it therefrom, substantially as hereinbefore
described with reference to the accompanying drawing.
