A New or Improved Machine for Treating and Dressing Malt.
We, JOSEPH SENIOR, of Rosa Works, in the City of Wakefield, Engineer, and
BENJAMIN HOLLINGWORTH WRIGHT, of Rosa Works aforesaid, Engineer, do here-
by declare the nature of this invention to be as follows:-
"
cums
"
This invention relates to a new or improved machine for dressing and treating
malt to remove the radicles and plumules (commonly termed "combs,"
or "cummings") as well as any fungaceous growth or the like and to generally
brighten the malt.
To carry out this invention we pass the malt through a wire-work or reticu-
lated cylinder revolving round a concentric shaft rotating in the reverse direc-
tion and having a number of inclined or radial screw blades adapted to propel
the malt through the cylinder. These screw blades are made of wood or other
suitable material and are sufficiently numerous, and are set at such a pitch, and
the cylinder is made sufficiently long, that by the time the malt reaches the
delivery end the growths etc. above referred to are to a great extent removed by
frication and a large proportion fall through the interstices in the cylinder.
The malt then preferably passes into a second wire-work or reticulated rotary
cylinder having a hollow screw or worm radiating from its internal periphery
and a number of radial projections are fixed longitudinally between the threads
of the screw, these latter are to more or less carry the malt round with the cylin-
der so as to spread it out as well as retard its passage through the cylinder.
Whilst the malt falls or passes from the first to the second cylinder a current
of air is preferably drawn or forced through it by a fan or other means to remove
dust and light impurities.
On leaving the second cylinder the malt may be raised by an elevator and
delivered into a conveyor provided with a number of sack spouts and a rotary
worm to convey it to such spouts.
The "combs" etc. drop into a receptacle below with inclined sides and a rotary
screw conveyor between them which passes the combs to an elevator preferably
arranged to deliver them into a sack."
The machine is enclosed by a suitable casing and two or more of each of the
cylinders may be fitted in each casing.
If desired the "combs" etc. from the first cylinder may be kept separate from
those from the second cylinder by a suitable division or partition in the casing.

We, JOSEPH SENIOR, of Rosa Works, in the City of Wakefield, Engineer, and
BENJAMIN HOLLINGWORTII WRIGHT, late of Rosa Works aforesaid, Engineer,
and at present residing at Garforth, near the City of Leeds, 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 state-
ment:-
cums
This invention relates to a new or improved machine for dressing and treating
malt to remove the radicles and plumules (commonly termed "combs," "
or "cummings") as well as any fungaceous growth or the like and to generally
brighten the malt.
To fully describe our invention reference is made to the accompanying sheets
of drawings, forming a part of this specification, in which similar letters of refer-
ence indicate corresponding parts in each of the figures.
Figure 1, is a side elevation of our improved machine in which the feed hopper
is shown broken away.
Figure 2, is a plan view of the same.
Figure 3, is a view of the front end.
Figure 4, is a longitudinal section, and
Figure 5, is half a cross section.
Figure 6, is a view of a detail hereinafter referred to.
The malt is fed into the hopper A and drops into the right hand screw pro-
peller A2 and on to the left hand propeller A which spreads it along
the plate A provided with adjustable openings A. The malt falls
through these openings more or' less filling the receptacle A beneath
into which the ends of the upper cylinders B and lower cylinders B
open. The cylinders B and 13 preferably do not rotate as described in
our Provisional Specification therefore it is only necessary to make their
lower halves of wire-work or reticulated material and the remainder may
be made of sheet metal. A concentric rotary shaft B4 is fitted in each
cylinder having a number of inclined screw blades B2 adapted to slowly propel
the malt, in proportion to the speed at which they rotate, along through the
cylinders. These screw blades are made of any suitable material but we prefer
to make them of iron and they taper to the edges and are twisted to or set at
about an angle of 10 degrees to a plane at right angle to the axis of their shaft
as shown in Figure 6 which represents a portion of said shaft and two of the
blades on a larger scale. The cylinders are made sufficiently long and the
blades B are sufficiently numerous that by the time the malt reaches the delivery
end the growths etc. above referred to are practically all removed by frication
(that is to say, by the grains rubbing against each other and against the blades)
and fall through the interstices in the cylinder, which interstices are not large
enough to allow the malt to fall through.
The malt falls out of the ends B of the cylinders onto the riddle H vibrated
by the cam H2 on the driving shaft F. The malt falls through this riddle in a
fairly uniformly divided shower into the receptacle C, and whilst it falls a cur-
rent of air is blown through it by the blower C² to remove dust and other
impurities.
The malt is raised from the receptacle C by the screw elevators D and D2 and is
delivered into the boxes E and E2 one on each side of the machine these boxes

page_text: may be fitted with sack spouts or their equivalent to enable their contents to be
run into sacks.
The elevators D and D2 are driven by the two pairs of bevel wheels D3, D'
and D5, D6. The wheel D³ is driven from the shaft E of the wheel D³ by the
spur wheels 17 and 18 the latter of which is fixed on the shaft E driven by the
chain E and sprocket wheels E and E, and the sprocket wheel E is fixed upon
the driving shaft F. The shaft F is mounted in the bearings F2 and F3 fixed
upon the framework G and drives the shafts 13 through the medium of the
wheels and B. The shafts B revolve in bearings B7 secured to the frame-
work G.
The lower sides of the cylinders are preferably brushed to keep their inter-
stices open by means of wire brushes shaped to the contour of the underside of the
cylinder. These brushes are mounted on endless chains and are driven in contact
with the cylinders from end to end.
The combs "horns" etc. removed from the malt fall either directly on to the
riddle or sieve J or on to the inclined sheet metal plates or shoots J provided
to catch them and from which they slip off into the sieve and by using a sieve
of proper mesh the greater part of the combs can be separated from the horns.
The sieve J is vibrated by the rod J³ from the crank shaft J driven by the skew
gear wheel J engaging the wheel J6-on the shaft F.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. A malt dressing machine consisting essentially of one or more perforated
cylinders each having an internal shaft provided with a number of inclined or
screw blades adapted when said shaft is rotated to dress the malt by frication
and propel it through the cylinder substantially as herein shown and described
and illustrated in the accompanying drawings.
2. In a malt dressing machine, the combination with a perforated cylinder
and internal shaft fitted with screw blades, of means for forcing a current of air
through the malting falling therefrom and a screw elevator for raising the malt
to a delivery chamber, substantially as herein shown and described.
