page_text: from the ends of the casing, so that the only direct air drafts are up between the
casing and the ends of the steam chambers.
E, is a vertical steam pipe, receiving steam from any proper source of supply, and
provided with branch pipes, F, that convey steam to each of the steam chambers, D.
These branch pipes, F, are provided with cut-off valves, f, so that the flow of steam
to each chamber can be graduated, or cut off entirely, when necessary.
G, is a vertical exhaust pipe, preferably on the other side and near the opposite end
of the casing from the steam pipe, E; and, H, H, are branch pipes connecting the
steam chambers and exhaust pipe, and provided with the cut-off valves, h.
By means of the valves, f, and, h, the flow of steam can be regulated through each
chamber separately as the necessities of the operation require, or steam may be
accumulated in each or any chamber until the pressure therein reaches the desired
point.
1,1', are two long pulleys on a shaft, i, receiving motion from any suitable motor,
and journaled in bearings on suitable supports.
J, J, designate a number of sets of pulleys on shafts, j,j, situated between the
opposite ends of each steam chamber and the adjacent end of the casing. The
pulleys, J, being on the opposite side of the casing from the pulleys, J.
The shafts,,, are journaled in bearings in the sides of the casing and the
pulleys, J, J, are secured in their respective shafts outside of the casing and at
different distances therefrom, so that the belts, K, K', by means of which said pulleys
receive motion from pulleys, I, will not interfere with each other.
The belts, K, extend from the pulley, I, to the pulley, J, on the shaft, 1, and crossed
belts, K', from the pulley, 1', rotate the pulleys, J', on the shaft, j', in a direction
opposite that of the pulleys, J.
L, L, are sprocket or chain wheels on the shafts, j, j', within the casing, and, M, M,
are chains connecting each pair of sprocket wheels and moving over the grain plat-
forms. The sprocket wheels and chains are arranged in equi-distant pairs corresponding
with each steam chamber.
It is evident from the foregoing that the chains move in opposite directions over
cach succeeding platform so that the grain in its descent is carried from end to end
of the casing.
The chains are provided with equi-distant cross bars or scrapers, m, m, and the.
chains of each pair move adjacent to the opposite vertical retaining flanges, d¹ of the
corresponding platform, d.
The machine is provided with the necessary bearing supports for the shafts, the
pillow blocks and other necessary and ordinary parts, which may vary in shape,
position and number according to circumstances and which as they are within the
scope of ordinary workmanship are not patentable elements except where they are
necessary to a new and useful purpose.
The method of operation is as follows:
The grain to be dried is poured in through the hopper and carried thence by the
highest chain over the highest grain platform by the described means. At the end
of the first platform it falls on the extension of the second platform and is carried by
the second chain in the reverse direction, falling on the third platform, and so on,
till it is delivered from the sixth platform into the discharging chute.
As the grain descends it becomes drier and loses a part of its moisture in the form
of steam in passing over each platform and the said steam being heated ascends and
converges and concentrates over the highest and shortest platform the greatest amount
of heat, where the heat is most needed, that is, at the top of the casing where it
immediately prevents or stops the fermentation of the grain, being then in its coolest
moistened condition. In fact the upward narrowing of the casing in connection with
the exhaust therefrom, causes the air and steam to pass more quickly over each plat-
form from below, upward, and the said air and steam become more hot as they ascend
because they receive successively the heat from the platforms. This action is equi-
valent to passing more and hotter air over the successively higher platforms during
the same time.

page_text: The increased length of the successive platforms as they descend permits a free and
direct upward escape of heated steam from the grain at the discharge end of each
platform after it has passed over the latter, which steam as it rises radiates its heat to
the grain on the successive platforms, but carries its moisture with it, so as not to
interfere with the drying of the grain.
The described action would be impossible if the casing were rectangular and not
narrower at the top than at the bottom, or if the successive platforms were not longer
at both ends than above, as each receives the grain from the platform immediately
above, at one end and allows the moisture to ascend in the form of steam from the
other end without imparting moisture to the platforms above.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In a grain drier, the combination with a suitable casing, a feeding hopper in
the top thereof and a discharge chute in the bottom of the casing, of the wing
wheels journaled therein, the horizontal steam chests successively increasing in length,
the lower chest extending at its ends beyond the ends of the chest above it, each
chest having connection with the vertical steam pipe, the cross belts, K¹, and the
belts, K, operating their respective pulleys, whereby the grain is moved in opposite
directions over adjacent platforms formed by the tops of the steam chests, substantially
as specified.
2. In a grain drier, the combination with the casing having converging sides, the
feed hopper, the exhaust flue, and the discharge chute, of the horizontal steam
chamber separately connected to the vertical steam pipe, the upper plates of said
chambers forming grain platforms, and the mechanism, substantially as described,
whereby the grain is moved in opposite directions over adjacent platforms.
3. In a grain drier, the combination with the casing upwardly converging the
feeding hopper and exhaust flue in the top of the casing, and the discharge chute in
the bottom thereof, of the horizontal steam chests successively increasing in length,
the lower chest extending at its ends beyond the chest or chests above it, the upper
plates of said chests forming grain platforms and having the flanged sides, and the
imechanism described whereby the grain is moved in opposite directions to the discharge
chute, substantially as specified.
4. In a grain drier, the combination with the converging casing, the feed hopper,
exhaust flue, and discharge chute, of the horizontal steam chests or chambers, each
successive chamber at its ends extending beyond the end of the chamber immediately
above, the upper plates forming grain platforms, and having the flanged sides, the
branch pipes provided with valves running from each horizontal steam chest to
the vertical steam and exhaust pipes the grain moving power consisting of
the belts, K, and, K³, pulleys, I, I, and pulleys, J, J, on the shafts, j, j¹, substan-
tially as specified.
