for Effecting the same.
I, JOHN LESLIE, of Souris, in the County of Kings, in the Province of Prince
Edward Island, Canada, Salesman, at present residing at Watson's Hotel, Aldgate
in the City of London, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The object of my invention is to effect the drying of grain in an improved and
expeditious manner, and to manufacture improved machinery or apparatus for
the same.
And in order that my said invention may be clearly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters
of reference indicate corresponding parts.
Fig. 1 is a side elevation of my invention.
Fig. 2 is an end elevation, shewing the upper end of the cylinder with the hopper
and feed.
Fig. 3 is an end elevation, shewing the lower end of the cylinder, and the furnace
door and shoot for the dried grain to fall out.
In carrying out my invention, I erect or build, or otherwise construct a suitable
casing a, which may consist of brickwork, ironwork, or any other suitable material
or combination of materials.
The air in the enclosed space is heated by means of the combustion of coals,
coke, wood or other suitable fuel, or by the spare heat from other furnaces or
operations of a similar nature. A furnace is shewn by dotted lines at b, Fig. 1,
and a furnace door b¹ is fitted thereto. This furnace (if used) is placed at the exit
end of the apparatus, in order that the grain may enter at the coolest end, and
receive increased heat as it travels towards the lower (furnace) end. A similar
arrangement is made with any other source of heat, the heat entering at the lower
end, and passing out by the chimney or flue c. d is a metallic cylinder, preferably
formed of thin wrought iron, and mounted on a short axle at each end. This
cylinder has small internal flanges, ribs, or other projections e e, for agitating,
turning and lifting the grains, as they travel down the revolving inclined tube, as
shown in Fig. 4.
The cylinder may be caused to rotate by means of water power (as shown in
the drawings) or by any other suitable means, f is a small water-wheel for driving

page_text: the apparatus, g is an upright shaft, which, by means of the bevel pinion h and
wheel i, axle k and wheel l, drives the spur wheel m. This spur wheel is fitted to
one of the short axles of the cylinder d, whereby the cylinder is caused to rotate.
m² is a spur wheel fitted to the short axle at the upper end of the cylinder d.
This spur wheel drives the pinion which is fitted with the shaker wheel 1,
having pegs round its periphery. These pegs successively raise the lever or
tappet n attached to the shoe p, and, as it rises and falls, it imparts a vibratory
motion to the shoe p, whereby the latter is shaken to assist the flow of the grain
into and through the shoot pl. o is the hopper for receiving the grain which is
fitted with a regulating shutter. q is the shoot at the lower end of the cylinder d,
which receives the dried grains, and from which it may be received into sacks, lifts,
or other receptacles.
The cylinder d is left open at each end, so that a current of air passes through
the same and carries off any vapour that may arise. r are two standards carrying
the bearing bar 8 which supports the gear and cylinder, at its lower end. By
shifting the position of this bar the inclination of the cylinder & may be regulated.
The outside of the cylinder is enclosed, at the lower end, in a vertical plate t
which is made to slide on the face of the structure a so as to render the joint
practically air-tight, with due allowance for raising or lowering that end of the
cylinder.
By the use of my invention the access of smoke to the grain is entirely pre-
vented; the moisture being carried away by a current of air, as described, and
the grain being turned over in the cylinder, the labor of spreading is saved, and
uniformity is, ensured.
My invention is applicable to the drying or roasting of coffee, malt, and all other
kinds of grain and seeds requiring analogous treatment.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The manufacture and use of the improved apparatus consisting of the adjust-
able inclined revolving cylinder d, having internal flanges, ribs or other projec-
tions e e, through which cylinder air enters at one end and is discharged at the
other, and other apparatus in connection therewith, arranged and operating substan-
tially as hereinbefore described and shewn on the drawings.
2. In combination with the improved apparatus as aforesaid, the use of the
hopper o, shoe p, and shaker wheel, substantially as herein before described and
shewn on the drawings.
3. In combination with the improved apparatus aforesaid, the use and applica-
tion of a furnace or other source of heat for heating the chamber in which the
cylinder is enclosed, substantially as herein before described and shewn on the
drawings.
L
4. The general combination and arrangement of the several and respective parts,
together forming my improvements in the method of drying grain, and in machinery
or apparatus for effecting the same, substantially as herein before described and shewn
on the drawings.
