combustion chamber. The engine was mounted on wheels as a 
portable engine. 
Messrs. Richard Hornsby & Sons, Ltd., Grantham (Stand 266). 
Several modifications have been made in the “ Hornsby-Ackroyd ” 
Engine since it was exhibited last year, and described and 
illustrated in the Journal. The principle of the engine remains 
the same, but whereas last year the oil was pumped direct into 
the combustion chamber, a governor regulating the supply by 
throttling the suction, in the present engine the petroleum 
pump — which is always running — is worked from the air valve 
lever, and the supply is regulated by a ball governor, which 
opens a relief valve on the delivery of the pump. A side shaft 
is now added, which, in addition to working the governor, 
actuates the air and exhaust valves through levers and cams. 
The modifications in the governing of the engine are a distinct 
improvement, as the engine tried last year was defective in this 
respect. Three engines were exhibited, of 12, 8, and 4 
indicated horse-power. A largo group of electric lights was 
shown, the dynamo supplying the current to which was driven 
by these engines, as illustrating a use to which, no doubt, such 
engines will be put. 
IV. “ Hay-Kickers.” 
The exhibit of back-action Haymakers, named at Windsor 
“ Hay-Kickers,” was very good and in excess of any previous 
Meeting. There seems to be a demand for them. They were 
all more or less alike, but generally claimed some special feature 
and improvement. 
This type of haymaker was introduced from the United 
States, as the “Bullard” Haymaker, in 1864. It is an 
American invention, the patent being dated September 1863. 
It was first shown in England at Bristol, at the Meeting of the 
Bath and West of England Society in 1864, and was then 
described as having a “ curious but effective ” action of the 
forks. Only about half-a-dozen machines were then sent over. 
One was sold for use at the Royal Farms at Windsor. Since 
then they seem to have received little attention until Mr. Gibbons 
exhibited the one at Windsor, for which he received a Silver 
Medal. 
Article 1374. Messrs. Ogle & Son, Ripley, Derby, exhibited 
a “ hay-kicker ” in which a special feature is that the height of 
the forks is regulated by a small wheel running in the rear, thus 
adapting it to uneven ground.
