THE MECHANICAL HANDLING OF MATERIAL
conveyor trough, this can be effected without making the conveyor more than 8 in. in
depth throughout. The inclined ends of this conveyor, and also the shoot which receives
the coke and a portion of the uptake which leads away the fumes, are shown in Fig. 207.
In the plan is shown the support for the terminals, one with the chain on, and the other
with the chain removed. Another modification of the De Brouwer conveyor is that of
Mr F. D. Marshall, of Copenhagen. The object of the device is to equalise the flow of
water by providing a sort of sluice for withdrawing the excess of water at any point in
the trough. This arrangement is shown in Fig. 208. The channels by which the water
is drawn off are fitted
with lids, in order
to facilitate cleaning.
The chief merit of
this arrangement ap-
pears to lie in pre
venting the water
from flooding that
section of the trough
which abuts on the
inclined plane, as at
that point the accumulation of water is sometimes so great that it overflows the trough.
Merz Hot Coke Conveyor.— I his conveyor owes its origin to a desire to
improve one of the first De Brouwer conveyors which was erected at the Cassel Gas-
works, and which
gave considerable
trouble owing to its
very light construc-
tion. The late Mr
E. Merz contended
that the round or
octagonal bars of
the De Brouwer
conveyor had not
sufficient hold on
the coke, which was
liable to slip back,
over or under the
bar; and also that
with the short links
in vogue at the time
it was impossible to
obtain chains of absolutely even lengths. He therefore designed the conveyor shown in
Fig. 209. Instead of the chains running in the bottom of the trough, they are concealed in
a suitable groove at the top, and the bars connecting the chains are replaced by cast-iron
rakes, which are supported by rollers. The prongs of the rakes being set at an angle, the
conveyor trough is relieved of a portion of the weight of the coke, thus reducing the work,
and also the wear of the trough. Ihe conveyor is built in two different patterns, viz.,
with the supporting rollers on the ends of the rakes, or with the supporting rollers fixed
to the trough so that the chain travels over the rollers. The former construction is
illustrated in Fig. 209, and the latter in Fig. 210, which also shows the general arrange-
