A New or Improved Machine for Cleaning or Washing Barley for
Brewing Purposes.
I, RUDOLF ANTON BAUMGARTNER, of Rosenheim, in the Kingdom of Bavaria,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is a machine for perfectly cleaning barley for brewing
purposes without prejudice to its germinating capacity.

The improved machine, which is placed into a suitable water-reservoir essentially
consists of a horizontally rotating brush-drum and a perforated mantle likewise
provided with brushes, a narrow working space being left between the respective
The machine is divided into three or more superposed
compartments, the upper of which receives through an adjustable slide the material to
be cleaned, which is first treated therein by a horizontal brush adapted to rotate about
a hollow vertical shaft passing centrally through and carrying the drum and having a
suitable number of pipes for supplying water to the vertical brushes. From the upper
compartment, the grain falls through a suitable aperture into the next, is brushed
between the drum and mantle and enters the next compartment through an aperture
on the opposite side and so on, until it falls into a transporting worm or other suitable
device for carrying it out of the apparatus.
Clean water is continually supplied to the space between the brushes from outside
through suitable pipes and from inside through the hollow shaft and the pipes referred
to above, the dirty water being pressed out through the preforations of the mantle and
removed through an outlet provided at the bottom of the reservoir.

COMPLETE SPECIFICATION.
A New or Improved Machine for Cleaning or Washing Barley for
Brewing Purposes.
I RUDOLF ANTON BAUMGARTNER of Rosenheim, in the Kingdom of Bavaria
Empire of Germany, Manufacturer 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 :-
The object of this invention is to provide an apparatus for effectually freeing barley
for brewing purposes from all adherent impurities, more particularly fine dust sand
and impure matter settled in the cleft of the grain without impairing the germinating
capacity of the material.
Referring to the accompanying drawing
Fig. 1 is a longitudinal vertical section of the improved apparatus, and
Fig. 2 to 5 represent details.
The improved machine which is placed into a suitable water tank A¹, is erected on a
base plate d, the posts supporting the shelves d which divide the apparatus into
three superposed compartments or storeys B, C and D. The upper compartment B
consists of an annular space containing two horizontally revoluble feeding brushes 6¹
serving to lightly brush the barley immersed in water and pass it through opening e¹
into compartment C.
The compartments C and D are formed by the brush drum c, secured to the hollow
vertical shaft, and the brush c¹ forming the mantle of the cylinder. The brush
drum c is supported by four hollow arms a¹ which serve at the same time as water

page_text: inlet pipes and are screwed with one extremity into the hollow shaft and with the other
connected with the brush drum proper by means of flanges over which is stretched
the brush mounted on sheet copper or equivalent material.
The drum arms' a' supply water through inlet pipe a provided in the hollow
shaft E, into the space comprised between drum c and mantle c².
The outer brush mantle c¹ and brush drum c consist of brush fibres of about 20
(twenty) millimetres in length, mounted on copper sheets or other convenient material
so as to leave a working space of about 30 (thirty) millimetres between mantle and
drum.
The mantle is moreover provided with small slots or perforations through which
the impure water is pressed out while the barley being treated, is continually in
contact with clean water which is partly supplied through the mantle from outside
by pipes a². From the compartment C the barley passes through the opening e,
(which is placed opposite to the opening e' leading from B into C) into the lowermost
compartment D, whence it descends through outlet E¹ on a transporting worm or
paternoster work which conveys the cleaned barley into the steeping vat.
el
The waste water is discharged from the tank through a cock provided at the bottom
thereof.
The washing of the barley is effected as follows:
Through the adjustable slide 62 the barley passes into compartment B, where it is
lightly brushed in clean water by horizontal brushes 6' for the purpose of macerating the
adherent impurities, hence through opening e¹ into compartment C, is brushed in the
space intervening between the rotating brush drum c and mantle brush c¹ while clean
water is continually admitted through pipes a¹ and a² and the waste water expelled
through the slots of the mantle. This operation is repeated in compartment D until
the cleaned barley passes through opening E' into the transporting worm for further
treatment.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A washing or cleaning machine for barley consisting of a rotary brush drum c, a
perforated brush mantle c¹, leaving a narrow working space between its brushes and
those of the drum and being divided into a number of compartments B CD, in
combination with a water tank A' and transporting worm, a horizontally movable
brush b¹ slide 62 and water inlet pipes a a¹ a², the whole disposed and operating sub-
stantially as set forth.
