Report on the Trials of Implements at Cardiff. 417 
lie ease and rapidity with which the operations of raising, 
)\vering:, folding, and unfolding, could be accomplished were 
onsidered as points of merit ; but strength and simplicity of con- 
ti iu'tion, and such a rigidity of parts as would secure the utmost 
.^gularity of work without the chance of any hitch, were consi- 
ered the most important requisites in this class. 
The nine machines entered for trial may be divided according 
) their construction into four sets. In the first set we have three 
lachines with a trough of fixed length that does not fold for 
ravelling ; each of them has a four-wheeled carriage-frame. This 
rame is rigid in Nos. 4945 and 5027, but in No. 4757 it is 
lade to expand in length. 
In the second set we have four machines on rigid four-wheeled 
arriage-frames, but with troughs that fold up for travelling. In 
^os, 4994, 5049, and 4848, the upper half of the trough folds 
ver and rests upon the lower half; but in No. 4978 the upper 
lart of the trough is doubled back under the other part when 
ravelling.

j The third description of elevator, No. 4982, has a folding- 
rough on an expanding four-wheeled frame. 
I The fourth mode of construction is that of No, 4998, in which 
)oth extremities are made to fold back under the middle part of 
trough, which, in travelling, is balanced upon a light tioo- 
vlieeled frame. In describing the machines separately it will be 
iioticed that the chief difference in principle of construction,
