secured into place by driving a taper steel split-pin through the 
hole, as shown in the illustration on page 503 (fig. 3). Any 
side thrust on the fingers is taken up by the bearing of the 
shoulder on the finger against the front edge of the finger-bar. 
A comparison of this bar with one of flat section by the 
same maker gave an advantage of about one-fifth in weight in 
favour of the former. The underneath side of the bar, with the 
fingers attached, presented a surface well suited for working 
close to the ground. The advantages claimed by this arrange- 
ment seem to be fully borne out, and its novelty and extreme 
simplicity met with the approval of the Judges. 
Mr. John V. Gibbons, Haseley Iron Works, Tetsworth, Ox- 
fordshire, showed the " Haseley Tedder," Gibbons's patent (Art. 
2984), the action of which may be best generally described as a

series of spring forks working with a very similar action to that 
of the Darby digger. 
The motion is given to two three-throw crank shafts by 
means of annular geared wheels on the main travelling wheels 
of the machine. On each of these cranks is a four-tined fork 
made of spiral spring steel ^-inch diameter, mounted on to an ash 
shaft, slung at about the middle of its length to the prank. The 
upper end of the shaft is connected, by means of two flat iron 
bars, to a pivot on the fore part of the framing. The forks with 
their shafts and pivoted connecting bars are called by the 
patentee " kickers." 
The brackets to which the connecting bars are pivoted are 
extremely simple. A light cast-iron bracket, with the base 
made to grip the wooden frame of the machine, has a projection 
on top with a wrought-iron pin cast in, on which the two bars 
connecting the upper end of the " kicker " are pivoted. On 
each side of this bracket there are two projections, placed so as
