and Miscellaneous Implements at Bristol.

when the digger has made a journey up the field and arrives at 
the headland, the tines are lifted out of the ground by the hand- 
wheel and screw, which forces backward the lever, on which the 
forward ends of the radius rods are hung. As it is forced back, 
the tines are raised out of the ground ; the land-side wheel is then 
released from its axle by the clutch, and remains stationary, 
while the machine is turned round by the other wheel. The 
machine is worked by three men and a boy. It is made by 
Messrs. J. and F. Howard of Bedford. 
In connection with steam-cultivating machinery may be 
noticed an improved Cultivator, shown by Messrs. Barford and 
Perkins of Peterborough, which has been still further simplified 
since the Meeting. The novelty consists in an arrangement by 
which the tines of the cultivator can be lifted out of the ground, 
or set shallower or deeper at any point of traverse, as well as at 
the land's end, by the action of the steersman ; the travelling- 
wheels are attached to a crank-axle in the ordinary way. The 
lifting power is attained by two scoop-shaped double-ended 
pawls on a crossbar on the top of the frame, and two notched 
wheels bolted to the bosses of the travelling-wheels. When 
these pawls are depressed, which is easily done by foot-leverage, 
the notches and pawls are brought together, when they lift the 
frame and tines clear of the ground. A pawl dropping in a 
catch holds them in position. When it is required to put the 
cultivator into work, the pawl is pulled out of the top catch, 
and dropped into some of the other catches on the quadrant, 
according to the depth required. This is a simple and efficient 
arrangement. Good steering power is secured by having a 
sliding draw-bar, looped on a crossbar, thus the draw-bar can 
adjust itself to the line of draught. Side thrust is thus removed, 
and the implement can be steered out of the line of the pulling 
rope. Two sizes were shown — a 7-tined costing 50/., and a 5- 
tined, price 35/. 
I cannot conclude this Report without expressing my acknow- 
ledgments to the Society's engineer, Mr. Anderson, for the great 
assistance rendered me by his examinations and reports on several 
of the machines which are therein described.
