Report on the Implements 
cultural Society to offer at the Plymoutli Meeting in 1890 prizes 
for disintegrators, the Judges were agreed in recommending that 
these two exhibits may be exhibited as new implements at the 
Plymouth Meeting of the Society, and classified as exhibits for 
special inspection. 
Messrs. Blackstone & Co., Limited, of Stamford, exhibited 
(Art. 4453) one of their well known prize haymakers, fitted 
with their new patent ratchet escapement. This recently 
patented improvement consists in adapting a ratchet box and 
pawl to each travelling wheel, so that when the horse stops 
suddenly, or relaxes his pace to turn, the flyers and teeth con- 
tinue to revolve by their own momentum. The clogging of the 
working parts in ordinary machines is generally caused when 
turning at the end of a swathe, as then, owing to the flyers 
ceasing to revolve, the grass which is on the teeth at the time 
di-ops on to the boss or axle, and this, when the horse goes on 
again, is wound tightly round, until in time the action of the 
machine is entirely stopped, and work is delayed whilst the 
obstruction is removed. When this patent ratchet escapement 
is applied, clogging is impossible, as the flyers continue to revolve 
after the travelling wheels have stopped, and thus any accumu- 
lation on the working parts is prevented, and the grass on the 
ground where the machine turns is tedded. Another important 
advantage of this attachment is that the gearing is entirely 
relieved of all undue strain. 
Messrs. Entwistle & Kenyan, of Accrington, exhibited an 
adjustable cap wrench (Art. 4928), for taking the oil caps off" the
