Improvements in the Method of Malting and Drying Grain, and in
Machinery or Apparatus therefor.
I, JAMES SLEEMAN, of Taunton, in the County of Somerset, Maltster, do hereby
declare the nature of my said invention to be as follows:-
The object of my invention is to effect further improvements in the methods of
malting described in the Specification filed with my former applications for Letters
Patent, No. 11,84489.
In carrying out my invention I fit the malting cases, described in such former
Specifications, with internal longitudinal shelves formed of sheet metal or other
suitable material, between the periphery of the cylinder or its equivalent, and some
or all of the outside tubes or framing, such shelves running continuously from end
to end of the case. When the case is revolved these shelves form lifts to carry the
malt upwards towards the top of the malting case, and then drop it, and thus
completely turn it over. I also fit such shelves between some of the tubes in the
centre of the case, for the better disposal of the grain during turning..
I also find it advantageous to fit such malting cases with exhaust and blowing
appliances, for exhausting and forcing hot or cold air therefrom or thereinto, and
through the same, or through the air passages forming part thereof.

Improvements in the Method of Malting and Drying Grain, and in
Machinery or Apparatus therefor.
I, JAMES SLEEMAN of Taunton in the County of Somerset, Maltster, do hereby,
declare the nature of my said 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 my invention is to effect further improvements in the methods
of malting described in the Specifications of Letters Patent Nos. 10,89189 and
11,84489.
In carrying out my invention, I fit the malting cases, described in the said former
Specifications, with internal longitudinal shelves formed of perforated or plain sheet
metal, or other suitable material, between the periphery of the cylinder, or its equivalent,
and some or all of the outside tubes or framing; such shelves running continuously,
from end to end of the case. When the case is revolved these shelves form lifts to
carry the malt upwards, towards the top of the malting case, and then drop it, and
thus completely turn it over. I also sometimes fit such shelves between some of the
tubes in the case, for the better dispersal of the grain during turning.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawing, representing a cross-sectional
view of the revolving case.
a is the outer cylinder, are the longitudinal shelves or lifts, which may be either
flat or curved. They extend from end to end of the cylinder, and are firmly fixed
to the periphery, or internal circumference of the cylinder, and to the ends thereof,
and, when necessary, are intermediately stayed or supported. These lifts are formed
of plain or perforated sheet metal, or of woven wire on a metal framework. When
the case is caused to revolve, the shelves or lifts bb carry the malt or grain upwards,

the grain. care sustaining wheels upon which the cylinder revolves. The case
may be so fitted that the tubes are fixed to the covers and revolve therewith; for
which purpose the cylinder is fitted with an air case at each end, in a similar manner
to that described in 11,84489. Or the case may be so fitted that the tubes may be
held stationary while the cylinder is caused to revolve; or the cylinder may be held
stationary, while the tubes are caused to revolve; or the cylinder and tubes may
revolve in opposite directions at the same time. For these purposes the air cases may
be fitted inside, independent of the cylinder covers, and sustained by a central tube
or tubes. Or, instead of such air chambers, a central tube. may be used with branch
pipes leading to the pipes cc; the central tube being divided by a diaphragm or plug,
so as to act as a pressure pipe at one end and an exhaust pipe at the other end.
The tubes e c are formed of perforated metal or wire gauze, each tube being fitted
with an iron bar d of an X sectional form, in order to impart rigidity to the tubes
and prevent sagging under the weight of the malt. These tubes may be fitted with
valves, as described in 11,84489.
I also fit the malting case with exhaust and blowing appliances, for exhausting and
forcing hot or cold air, therefrom or thereinto, and through the same, from one air
chamber to the other. By closing the valves of some of the tubes in the chamber
where pressure is applied, and closing the valves of the remainder of the tubes at
the opposite ends, in the chamber where the exhaust is applied, I am enabled to use
some of the tubes as blowing tubes, and the remainder as exhaust tubes, while the
cylinder, or the tubes, or both, is or are revolving. The same effect may be produced
by increasing the pressure of the incoming fluid, and allowing the exhaust to flow
outwards at atmospheric pressure. The valves may also be worked in the manner
described in 11,84489, by weighting the valves so that they shut off the air from
the upper series of tubes, and open again when carried down. Also the valves at
the exhaust ends of the tubes may be weighted so as to open when above the axis,
and close when below the axis. By this arrangement the fluid, at high pressure, flows
out of the lower tubes, up through the malt, and out through the upper tubes to the
exhaust chamber.
The malting is effected in a similar manner to that described in 10,891
and 11,84489; similar advantages being derived from its use, as also described in the
same Patents.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The improvements in the method of malting and drying grain, and in machinery
or apparatus therefor, substantially as herein before described and illustrated by the
drawing.
2. In machinery or apparatus for malting, and drying grain, the combination of a
cylinder, fitted with lifting shelves bb, and perforated tubes c, c, severally operating
substantially as herein before described and illustrated by the drawings.
