framework of wood, supported at one end by a couple of struts, 
and at the other bj a stake, which is driven into the ground, 
the height of the fan-wheel being easily adjusted to the stack- 
flue by raising or lowering the framework and fastening it at 
the required height to this stake. When the fan is to be moved, 
the driving-wheel acts as a wheelbarrow-wheel. 
Nothing could be more simple than this machine. The strap 
used was of untanned leather, and in the field one man main- 
tained an average speed of 60 turns of the handle per minute 
for a considerable time. This gave 1050 revolutions of the fan 
per minute. The horse-power required to effect this was, accord- 
ing to the dynamometer trial, "33, while the displacement shown 
by the water-gauge at this velocity was •? inch. 
Stand No. 113. — James Coultas, of the Perseverance Iron Worhs,

Article 2224 — Hay and Cora Drying Apparatus; manufactured by the- 
Exhibitor. Price 15?. This patented apparatus conditions liay, com, seeds, 
and all classes of grain iu the straw, while in the stack, and enables the above 
to be carted at a much earlier date ; the heat and damp can be drawn off at 
pleasure by the use of exhauster driven by ordinary steara-eugiue. Extra if 
mounted on wheels and fitted with shafts, 3/. (For Trial.) 
This was the monster machine of the Exhibition (see Figs. 
2 and 3) ; the construction of it is, however, simple enough. The 
fan, which is 36 inches in diameter, has four blades, l4 inches 
wide and 12 inches deep, and works in the centre of the enclos- 
ing case. A 7^-inch pulley on the outside is driven direct 
from the fly-wheel of a 4-horse'power engine. Three circular 
inlets (see Figs. 2 and 3, A. B. and C), 9 inches in diameter, 
are provided, each one of which can be connected with a separate 
stack or range of stacks, and any one of these branches may 
be closed or opened instantly by inserting or withdrawing a 
slide or damper. The fan is mounted on a pair of strong road- 
wheels, and is fitted with shafts for removal. Attached to the 
front framework are a couple of strong upright planks, which 
rest on the ground, and support the machine in position. The 
inlets for the air are some 30 inches above ground, and the con- 
nection between them and the earthenware pipes is effected 
by means of cylindrical sheet-iron tubes, which proceed at first 
horizontally, and then turn at a right angle downwards. This 
is a somewhat important point to notice, and it seems necessary 
to call attention to it, because the published plates show a 
gradual curve in place of the abrupt turn actually taken.
