Report on the Trials of Implements at Reading. 657 
Stand No. 283. — Charles D. PMlips, of the Emlyn Engineering 
Works, Newport, Monmouthshire. 
Article 5232— Implement.) — Fan ; manufactured by the Exhibitor. 
Price 91. Phillips's improved exhausting and ventilating fan for stack cooling, 
or harvesting in the stack, with bearings outside, so that dust, sand, fibres, 
vapours, heated gases, &c., can pass through the fan without touching or 
injuring bearings. With steel spindle and long bearings, provision for 
efficient lubrication. Power required to drive it, 1-horse. (For Trial.) 
5233— (Not) Implement.) — Fan; manufactured by the Exhibitor. Price 121. 
Phillips's improved exliausting and ventilating fan. Similar to Article 
No. 5232, but mounted on pedestal and wheels, with self-contained counter- 
shaft and pulley for driving by horse gear and intermediate motion. (For 
Trial.) 
The fan (see Figs. 5, 6, 7) in these machines (which are in 
that respect identically the same) is a drum like that of a centri- 
fugal pump, 15 inches in diameter, with tapering blades 1^ inch 
wide at the tip, 4^ inches wide at the centre (see Fig. 6). The

drum revolves in the centre of the case, the air entering on both 
sides of it. The machine is entirely constructed of iron, and is 
mounted on four wheels. When worked by hand-power a spur 
wheel drives a pinion, on the shaft of which is an 18-inch pulley, 
from which a strap runs on a 5-inch pulley. The ratio of speed 
of the motive wheel to the fan is 27 to 1, so that with forty 
turns of the handle per minute 1080 revolutions of the fan are 
given. When worked by steam-power a 5-inch pulley is sub- 
stituted for the pinion wheel, and driven directly by a belt from 
the fly-wheel of the engine. By this means a speed of 2500 
revolutions is easily obtained. The dynamometer trials gave 
1*77 as the horse-power required to get 2160 revolutions; but 
m the field a li-horse-power engine, working at very moderate
