collecting main on top and the’gas' is taken off by two
diagonal channels on the top of both ends of each retort.
As the retorts are covered by lids of equal size, it is, of
course, not possible to run rails along the top of the
ovens and the charging machine runs thus on two rails
suspended, at right angles to the ovens and supported
by heavy girder structure. These structures, running on
both sides along the battery and carried up high enough
to receive the charging car, are strengthened and jointed
together by heavy cross girders 13, one for each oven
and in line with these. The side girders carry on each
side a rail line 14 on which, with four travelling wheels
15, runs the charging machine. It consists mainly of
a large hopper 23, which contains one oven charge and is
closed on the bottom by a toothed roller 25, driven by
chain from a motor 25. The machine forms a strong
skeleton of iron construction which holds all the
machinery belonging to it. A motor 32 actuates the

plate 30 reaches the corner of the oven. Then the motor
26 is started and by rotating the toothed roll 25, the
coal is evenly discharged into the oven. In case it is
necessary to compress the coal, this can be done direct
in the oven as is shown in fig. 20. The bottom girders
of the machine carry a compressing machine 21, travel-
ling in line with the oven and driven by the motor 42.
The starters and controllers 55, of the four motors are
all placed together in one driver’s cabin, so that only
one man is required to operate the whole arrangement.
The machine is covered in so that the gas given off while
charging does not enter the interior of the machine.
After the oven has been filled the retort cover is replaced
and the car returns to the coal bunker to receive the next
charge.

Messrs. Jenkins and Company Limited, of Retford,
who have been so successful with their De Brouwer
charging machines for gas retorts, have brought out a

Fig. 21 shows the charging machine of the late Dr.
Schniewind, of New York, which is specially designed
to charge ovens of very large capacity. The ovens them-
selves differ also from the usual type, inasmuch as there
are no charge holes on top, but the top of the retort
forms a single cover which, when removed, opens the
whole area of the retort. There can, of course, be no

winch 36, by means of a worm drive, for lifting the retort
covers 31. A further motor 53, engages, by suitable gear-
ing, with the travelling wheels. The machine travels
over the battery like a large overhead crane; after the
hopper has been filled under the bunker the machine
travels to the oven to be charged and raises the retort
cover. It then travels a little further until the guide

machine to charge coke oven retorts on the same prin-
ciple. The charging machine which is shown in .fig. 22
may be combined with the pushing machine, or if built
separately, travels on the same rails. The machine
consists of a girder skeleton, and carries on top a hopper
A, large enough to hold one charge. It receives its coal
from the stationary bunker B. Inside the hopper A is
