456 Report on the Trials of Implements at Cardiff. 
many of the other machines exhibited, but was stated to include delivery to 
all parts of Great Britain ; it also includes the fitting s required for working by 
steam in conjunction with a threshing-machine. 
Fig. 26. — Lewin's Patent Staclcer,^'No. 5048, closed for travelling. 
No. 4978. WalUs and Steevens. — The same machine as described in Class IV., 
except that the gearing required for working by steam bad been removed, and 
that the folding apparatus was of wood resting on the ground, instead of being 
of iron supported on the frame of the elevator itself. These two alterations 
reduce the price of the machine by 5/. 4s. &d. 
No. 4846. Albert Watson. — A machine similar to the one described in Class 
IV., but without the extra pulley needed for working with a threshing-machine. 
In this trial the evil of using very slack chains not sufficiently supported was 
exemplified. Soon after starting the machine came to a dead lock, and several 
attempts were made to start it again before it was discovered that two of the 
links had been doubled up and were acting as a wedge between the toothed 
driving-wheel and the bottom of the carrying-trough. 
No. 4230. IMmes and Sons. — This machine is constructed on the principle of 
the railway travelling-crane. The elevator frame and trough are raised above 
the carriage-frame, and are balanced upon a pivot passing through its centre. 
The horse-gear is, in this case, an integral part of the whole machine, and is 
placed between the carriage-frame and tlie frame of the elevator. The horse 
in working passes under the trough and within the two props that serve to 
keep the upper frame steady. The trough is raised and lowered by means of 
chains and rods. About one quarter of its length is made to fold under for 
travelling. I'he power is conveyed from the horse-gear to the octagonal wheels 
that move the ladder-chains by means of toothed chain-wheels and pitch-chains. 
The chief merit of this machine is the great facility with whicli it may bo 
moved from phice to place and set to work ; the horse-gear being on the frame 
requires no adjustment, and the trough, having an indejiendent movement, can 
be shifted by hand to deliver hay to any part of the stack without moving 
the carriage-frame. In its present form it has one serious disadvantage, it 
does not fold up into a moderate compass, but is very inconvenient to put under 
cover on account of its great length and height. Its workmanship aUd the 
materials used are good. 
No. 64. JL arid J. Reeves and Son. — This machine is the invention of W. 
Andrews, of Melksham, improved and manufactured by tlic exhibitors. It is 
of light construction and low in jirice. There are four travoUing wheels, but no 
fixed carriage-frame; the trough issujiporttd in front by a bolt passing tlirougli the 
heads of two wooden shafts, whicli are carried upon tlie axle of tlie fort-whcels.
