Various “ New Implements .”

Article 199. — Mann's Patent Steam Cart and Wagon Co., 
Ltd., Pepper Road Works, Hunslet, Leeds. “ Wheel for winter 
use for self-propelled road engines, agricultural and otherwise ; 
with wood block rims held in place by adjustable steel side 
plates which can be moved inwards towards wheel centre as 
wood blocks wear away.” 
To prevent a power-driven lorry from skidding on either 
ice or thick mud is the earnest desire of all users of that type 
of vehicle, and we were very sorry that the exhibitors could 
not show us a wheel that had been in use for a few thousand 
miles, as this would have better enabled us to judge of the 
wearing qualities of the wood blocks. 
Article 210. — Messrs. T. G . Slipper & Co., Brundall, 
Norwich. “ Petrol Engine, ‘ Eli,’ 3 H.P.” — This engine was 
fully described in last year’s Report (see pp. 196 and 197 
of Yol. 65 of the Journal). The novelty consisted of a 
particularly ingenious ignition device, the method being to 
advance the spark, as the speed increased, by means of a 
centrifugal governor on the crankshaft. This arrangement was 
so timed that the point of ignition could never be advanced 
beyond dead centres when the engine was being turned slowly 
for starting purposes, thus entirely avoiding the chance of a 
back fire. 
Article 224. — Messrs. E. H. Bentall A Co., Heybridge, 
Maldon, Essex. “ Chaff Cutter ; Patent Bentall ‘Unbreakable.’ ” 
— This was a chaff cutter designed in such a manner that the 
bottom mouthpiece should drop out in the event of a hard 
foreign substance passing through the feed rolls to the knives. 
This was accomplished by securing the bottom mouthpiece in 
place by small cast-iron blocks. The blocks were constructed 
of iron of a very brittle nature, and of such a cross section that 
they would break on the knives coming in contact with any 
substance sufficiently hard to damage them materially. 
Article 917. — Messrs. Burmeister Wain, Ltd., 12 
Coleman Street, London, E.C. “ Milk Can, 9 gallons, made 
entirely in one piece, with T-shaped bottom hoop, with side 
handles and lid, also made in one piece.” 
These milk cans, owing to their being constructed from 
one piece of steel, are extremely strong, but from their small 
capacity are more fitted for the retail milk vendor of the town 
than the farmer who sends his milk there by train or otherwise 
in large churns, such as we see in the West of England. 
Articles 1254, 1255, and 1256. — Dairy Supply Company, 
Ltd., 28 Museum Street, London, W.C. The Dairy Supply 
Company exhibited three implements which they claimed to 
be novel, wiz., an Alkaline Milk Tester, a Rotary Milk Strainer, 
and a Butter Churn and Worker combined. These exhibits are
