PROVISIONAL SPECIFICATION.
An Improved Apparatus for Removing Grain and other Substances
from Malt Kilns, Granaries, and like Places.
I, SIEGFRIED HIRSCHLER, of Worms on the Rhine, in the Empire of Germany,
Maltster, do hereby declare the nature of this invention to be as follows:-
My invention relates to apparatus for clearing, discharging and conveying malt or
grain from malt kilns, granaries and similar places.
Hitherto it has been the practice to clear the malt from malt kilns by hand, which,
by reason of the great heat of the kiln has been found very fatiguing and costly as it
occupied considerable time and a large number of hands.
My invention has mainly for object to provide mechanism for performing this
operation and for conveying the malt away as it is discharged from the kiln.
The apparatus comprises two endless chains or bands running over chain wheels
operated by hand or power. The said chains carry transverse boards or scrapers of
varying depths extending across the floor of the kiln or the like so that each scraper
shall carry along a thin layer of the grain or other substance. The chains also
carrying brushes which follow the last and deepest scraper and completely clear the
floor.
When requiring to clear the material from each side of a chamber towards the
centre I employ two sets of the herein before described scrapers and brushes and
provide one of the sets with rollers running on rails so as to raise the scrapers and
brushes thereof above the material on one side of the chamber after they have cleared
the other side of the chamber. By means of a self-reversing device the chains are
then made to travel in the opposite direction thereby causing the other set of scrapers
and brushes to clear the material from the first named side of the chamber.
1
The conveyor which in. this case is arranged in the centre of the floor and receives
the material as it is cleared from each side of the chamber, consists of an endless band
having boards placed at intervals across it the band passing over two pulleys driven
by suitable means. The conveyor would however obviously be arranged at one side
of the floor when only one set of scrapers and brushes is employed.
The conveying boards can be made of wood or other suitable material and forks can
be used instead of or in combination with the same.
The apparatus can also be employed for transporting green malt in cellars, as well
as all sorts of grain in granaries and the like.

COMPLETE SPECIFICATION.
An Improved Apparatus for Removing Grain and other Substances
from Malt Kilns, Granaries, and like Places.
I, SIEGFRIED HIRSCHLER, of Worms on the Rhine, in the Empire of Germany,
Maltster, 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 :-
My invention relates to apparatus for clearing, discharging and conveying malt or
grain from malt kilns, granaries and similar places.
Hitherto it has been the practice to clear the inalt from malt kilns by hand, which,
by reason of the great heat of the kiln has been found very fatiguing and costly'as it
occupied considerable time and a large number of hands,

page_text: My invention has mainly for object. to provide mechanism for performing this
operation and for conveying the malt away as it is discharged from the kiln.
In the accompanying drawing,
Figure 1 is a section of the floor of a malt kiln fitted with my apparatus for clearing
malt from each side thereof towards the centre and for conveying it away.
Figure 2 is a section taken at right angles to Figure 1.
Figure 3 is a view of a portable apparatus adapted to be easily moved to any part
of a kiln or large warehouse for. effecting the removal of a portion of the malt, grain
or the like therefrom.
Figure 4 is a view taken at right angles to Figure 3.
The apparatus adapted to clear malt from each side of a malt kiln and to convey it
away as illustrated in Figures 1 and 2 comprises two endless chains or bands K¹, K³
running over chain wheels R, R, RR each pair. of which is keyed to a common
shaft. The chain wheels are operated by a pulley S fixed on the shaft A of one pair
of the said wheels and driven by a belt L from a steam engine or other suitable
source of power. The chains K1, K2 carry two sets of transverse boards or
scrapers a, b, c, d, e, f, g, h and a¹ b'c'd¹e¹ƒ¹ g¹³ of varying depths extending
across the floor of the kiln or the like so that each succeeding scraper of a set shall
enter deeper into and carry along a thin layer of the grain or other substance. The
chains K, K³ also carry two sets of brushes m, n and m¹, n' which extend across
the kiln and follow the last and deepest scrapers and hand completely clear the floor.
I provide one of the sets of boards or scrapers and brushes with rollers at each
end running on rails t so as to raise the said scrapers and brushes above and clear of
the material on one side of the chamber after they have cleared the other side of the
chamber. By means of any known suitable self reversing device the chains K'
and K2 are then made to travel in the opposite direction thereby causing the other
set of scrapers and brushes to clear the material from the first named side of the
chamber.
'
The wheels or rollers C serve to carry the upper part of the chain and the wheel D
serves to guide the lower part.
The conveyor which in this case is arranged in the centre of the floor and
receives the material as it is cleared from each side of the chamber consists of an
endless band B having boards placed at intervals across it the band passing over
- two pulleys R¹ and R driven by suitable means such as the shaft A¹ and pulley S¹.
The conveyor would however obviously be arranged at one side of the floor when
only one set of scrapers and brushes is employed.
The operation of the apparatus is as follows:-
As in the present case the conveyor is situated in the centre of the kiln the
clearing boards and brushes are caused to move towards the centre. The clearing
is therefore effected by two distinct operations, that is to say, the left side of the
floor of the kiln is cleared first and then the right side is cleared.
The drawing represents the apparatus with the parts in the position they occupy after
having cleared the left side of the kiln by means of the boards a, b, c, d¹³, e¹², f, g¹, h¹
and brushes m', n' through the chains moving in the direction indicated by the
dotted arrows, the self reversing device being on the right hand side.
In order to clear the right hand side of the kiln the reversing device is first
placed on the left hand side and the apparatus is reversed so that the chains and
clearing boards and brushes shall move in the opposite direction indicated by the
plain arrows.
The clearing boards a, b, c, d, e, f, g, h then move along until the first board a
reaches the material and removes the first thin layer.
The next board being made a little wider than the previous board a enters
deeper into the material and consequently removes another thin layer and so on
till the last board h extending to the floor reinoves the last layer from the bottom.
Any material which is left behind is then swept along by the first brush m and
finally all dust is properly swept away by the second brush n and the clearing
operation is completed,

page_text: The manner in which the left hand side of the kiln is cleared by the boards a¹, b¹, c¹
etc. and brushes m', n' is practically the same as that described for the right hand
side and will be understood without further description.
This arrangement of clearing the one half of the kiln floor before the other is
necessary in all kilns which are fitted with a self acting malt turning apparatus.
The one half of the floo: having been cleared the self acting malt turner is run over
and the other half of the floor can be cleared.
If the conveyor be placed at one side of the apparatus which is especially
recommended in the case of small kilns the chains would only have one set of
planks a, b, c, d, e, f, g, h and brushes m, n. which would be made to move in one
direction only the work being done in the manner before described.
When the apparatus is arranged to be worked by power it can be fitted with an
automatic stop which at the end of one or several rotations would arrest its move-
ment.
The portable apparatus represented in Figures 3 and 4 also comprises two endless
chains K and K2 running over the chain wheels R cach pair of which is keyed to
a common shaft and it is worked by means of a crank handle K.
The boards a, b, C, d and brush m are made as before described and fixed by
suitable means to the chains.
The shafts of the chain wheels are supported by a wooden frame G. This frame
is mounted on rollers (not shown in the drawing) to facilitate the removal of the
apparatus. The conveying boards work between the two longitudinal beams B.
1
It may be here mentioned that the conveying boards can be made of wood or other
suitable material and that forks can be used instead of or in combination with the
same.
The apparatus can also be employed for transporting green malt in cellars, as well
as all sorts of grain in granaries and the like.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
1. An apparatus for removing grain, seeds and other substances from malt kilns,
granaries and like places comprising a number of boards and brushes mounted on
endless chains which are caused to move in a horizontal direction over the said
substances the boards being arranged so as to carry the substances away by removing
a thin layer at a time and the brushes finally completely clearing the floor.
2. The improved apparatus, illustrated in Figures 1 and 2 of the drawings, for
removing grain and other substances from malt kilns, granaries and like places the
said apparatus consisting of the two endless chains K', K2 running over the wheels R
each pair of which is keyed to a common shaft operated by means of the pulley S
on one of the said shafts and the belt L, the said chains carrying boards of various
depths and brushes, one set of boards being provided with rollers running on
rails t for the purpose of raising them so as to allow a self acting malt turner or
similar apparatus to be passed below, the whole being arranged and operating sub-
stantially in the manner and for the purposes set forth.
3. The modified form of apparatus illustrated in Figures 3 and 4 adapted to be
easily moved from one part of a kiln or warehouse to another, substantially as set
forth.
