line, the two operations being performed by means of an ar- 
rangement of knives fixed on one shaft. The material is 
delivered to the outer part of the open mixer, and is carried 
forward by the knives to the pug-mill, from whence it is fed 
into one of four moulds placed at right angles in a revolving 
cylinder 18 in. in diameter. The cylinder remains stationary 
while the mould is being charged. The action of filling the 
mould automatically dischai'ges the brick already formed, and is 
a simple but effective contrivance. As the brick issues from 
the cylinder it falls into a convenient position, and is fed by a 
self-acting arrangement direct into the mould of the press. The 
pressed brick is then automatically raised out of the press-mould, 
and delivered in a suitable position for being loaded into a 
barrow or other vehicle, and taken to the kiln. The output of 
the machine is from 10,000 to 12,000 bricks per day of ten 
hours, and the cost is 300Z. The bricks are well finished. 
Mr. Thos. Constantine Fawcett, Whitehouse Engineering 
Works, Hunslet, Leeds, exhibited his Brick Making and Pres- 
sing Machine (Art. 3671), in which the pressure is applied to 
the bricks by means of the toggle system of levers, which gives 
two distinct differential pressures to each brick. The working 
parts, which are all made of steel, are interchangeable and few 
in number, and can all be seen while the machine is in work. 
The machine is capable of turning out a good brick in a semi- 
plastic or semi-dry state from fine clay, marl, shale, &c., when 
passed through a mixing pan to incorporate the water with the 
ground material. From 8,000 to 10,000 bricks can be made 
per day with a reasonable amount of driving-power ; they are 
easily delivered from an open-ended moulding cylinder, and are 
automatically passed from it to the press, where they receive 
the two pressures, and are then automatically delivered on to 
the table ready to be taken away. The machine can be driven 
from either side, and made to deliver the bricks on the side 
that is most convenient. It is fitted to make fire-bricks and 
glazed bricks. There is a special oiling apparatus, which con- 
sists of a fan creating a current of air, which meets the oil 
as it drops, and causes it to fall in a fine spray over the open 
mould. The work is done steadily and well, and there is every 
indication that the machine is very durably made. The price 
is 200^. 
Messrs. E. Foden, Sons, & Co., Limited, Sandbach, showed 
their Tandem Compound Traction Engine, with piston valves 
(Art. 4153). This is an ordinary compound tandem engine, 
the cylinders being placed close behind one another. The special 
feature, however, consists in the arrangement of the slide valves,
