the anpiular arrangement of the frame receives the bearings held in place by 
one adjustable pin. Price, 11/. 10s., with one pulley. 
Mellard's Trent Foundry Company were highly commended for 2-Horse 
Gear, No. 5222. Frame of cast-iron in three parts. Standards attached to 
bed-plate by nuts and screws. Diameter of driving-wheel about 4 feet. 
Wrought shaft, with brass step in a square box. Centre of shaft drilled to 
allow of oiling. Pinion shaft, of wrought iron, carried ou brass bearings. 
Clutch for in-and-out gearing. Intermediate motion frame of cast iron. 
Brass bearings throughout. Appears a strong, useful gear — not out of the 
way at 12?., especially as this price includes one pulley. 
Coleman and Morton were commended for 1-Horse Gear. No. 1697 com- 
prises a strong oak frame, to which is attached by bolts, the saddle of 
ribbed cast-iron, which is all in one piece. Driving-wheel, 3 feet 6 inches 
diameter. The shaft is carried in a bush attached to the saddle. The shoe 
consists of an iron plate. The bearing on the saddle is adjustable by a set 
screw. Pinion and shaft strong. Intermediate motion very light. Case- 
hardened cast-iron bearings. Price, 111. 10s. 
No. 1698 also commended. 2-Horse Gear. — This diifers from the last in 
having the shaft hollow, cast in one piece with the frame. The driving-wheel 
revolves on a stationary shaft. No saddle frame above required. Works very 
steadily. Price, 15?. 
As both Thomas Corbett's Gears were commended, and as they differ little 
but in strength, we shall confine our attention to No. 6339, that for 2 horses. 
The foundation plate is of cast-iron. The brackets, also of iron, are screwed 
to the foundation plate. The driving wheel is a bevel about 4 feet diameter. 
The shaft works in a cast-iron shoe bolted to the foundation plate, admits of 
adjustment by packing. Large friction wheels to steady, and to keep the teeth 
of driving-wheel well up to their work. The shaft is square, with turned collar 
and bored collar-plate, set in a cross-piece of oak ; by this arrangement the 
rigidity of the driving-wheel is increased. The intermediate motion pulleys 
are supported on cast-iron brackets, and there is the peculiarity of an extra 
gearing by which a pulley can be worked at right angles to the ordinary 
pulley shaft, if required. This may be convenient in some cases, but there 
must be some loss of useful force by additional friction. In the event of the 
load being suddenly removed — as by a belt tlying off or the work ceasing, or 
when the chaff-cutter is thrown out of gear — a break can be applied so as to 
prevent the pole acquiring an increased speed and striking the horse. Price, 
15?. 10s. 
The Reading Iron Works, Limited, were commended for No. 4011, a 1-Horse 
Open Gear. — Here the means of getting the speed is all contained within the 
frame. The gear is well made. Cast-iron double-angle frame, with comer 
bolt-holes for fastening down. The driving-wheel 2 feet 8 inches diameter, 
with turned periphery and friction rollers, fixed over the bevelled pinion, 
which is keyed on to a short shaft taking the spur wheel which gives the 
second motion. The shaft works in a chilled step. Long bored journals 
and turned bearings, in place of brass. The cap or top for the whole 
removable and easily replaced. Price, 7?. 7s. This is certainly a very cheap 
gear. 
Williamson Brothers, of Kendal, were commended for a 2-Horse Gear, No. 
G736. — Here again the speeds are all on the frame. A ratchet-wheel attach- 
ment is provided, which prevents the pole pressmg on the horses when the 
latter are stopped sharp, or when the load is removed suddenly. Diameter of 
driving-wheel about 4 feet 7 inches. Main shaft cast ; smaller ones wrought. 
Bearings of brass. Frame in three portions ; brackets bolted to the frame. 
Cross bar iu two parts, bolted together and to the brackets. The shaft is
