of the machine is open, and therefore permits crops of any

The Trent Gas Engine Co., Limited, New Basford, Notting- 
ham, showed a rapid and accurate Weighing Machine (Art. 
3835) for weighing grain, cement, &c. It consists of a hopper, 
a grain vessel for receiving the gi'ain, and the weighing ap- 
paratus, all carried on a small and convenient frame. AVhile 
filling, the grain vessel is securely locked in a vertical posi- 
tion. "Wheat, or other material to be weighed, enters b}" the 
funnel-shaped mouth until the greater part of the charge 
has run into the grain vessel, when a valve or flap closes, 
and the remainder passes in thin streams, taking the place 
of sprinkling by hand. The discharged port is meanwhile 
held closed by a flap hinged to the grain vessel, and resting 
on it by its own weight. When the exact weight required 
has entered, a second valve closes the inlet entirely, and 
then, by its own weight, releases the grain vessel. The gi'ain 
vessel then rocks a few inches foi'wards and inwards, and, the 
flap being held back by stops on the frame, uncovers the dis- 
charge port, whereupon the wheat quickly runs out. The grain 
vessel then at once returns to its original position, on its way 
taking up the flap which closes the discharge opening. The 
return of the grain vessel re-opens the inlet valves, after the 
discharge opening has been closed, and records the weighing, 
whilst a new weighing immediately commences. 
The machine was worked in the Showyard by one of the 
company's gas-engines, and the greatest accuracy was obtained, a 
small coin being sufficient to move the balance. The machines 
are made to weigh from 2,100 lb. to 180,000 lb. of wheat per 
hour, the prices being 20/. and 220/. respectively; whilst there 
are. in addition, seven intermediate sizes. They would, therefore, 
be found very useful in granaries where considerable quantities of 
corn are constantly received, or would be useful for weighing out 
" feeds ■"' of corn for horses in large stables. They would be 
equally valuable for cement sellers, manure merchants, and all 
dealers in dry, meal-like substances. 
Mr. WiUiam Johnson, Castleton Foundry, Annley, Leeds, ex- 
hibited his " Stiff"-Plastic '" Brick Making and Pressing Machine 
(Art. 3675), in which are complete arrangements for mixing, 
pugging, moulding, and pres^ing. The grinding-mill is fitted 
with pulverisers, liorizontal rollers, or perforated edge runner 
mills, so that whichever is found most suitable may .be 
worked. The clay is served direct from the mill to the ma- 
chine by means of a shoot, or by a shovel from a plat- 
form. The mi:£er f\nd pug-mill are situated in one horizontj\l
