COKE FROM COKE OVENS

One of the first attempts at mechanical loading was the installation of a portable
band conveyor, mounted on wheels, and running on three rails right across the hearth, as
shown in Fig. 502, constructed by Coulson & Co., Spennymoor. The conveying band a
reaches close to the ovens and can traverse the whole of the hearth in front of the
battery of ovens. The delivery end reaches to the middle of the trucks. The conveyor
is fitted with electric motor, and the current is taken from an overhead wire on lamp
standards by a trolley, so that the motive power is available in whatever position the

conveyor may stand. The conveyor is driven close to the quenched and cooled coke to
be loaded, set in motion, and the coke is then put on with the usual large forks which
leave the breeze on the hearth. The utility of these and similar transporters is somewhat
marred as the quenched coke on the hearth restricts, the movements of the conveyor to
narrow limits, and therefore makes it impossible to load the coke in the rotation in which
it is pressed; it has rather to be taken from the spot where the conveyor may happen to
stand. There is no apparent mechanical objection to erect such bands on carriages

sufficiently high to clear the coke on the hearth, but then the rails would have to be
cleared for its passage. The latter difficulty has been overcome by the Baglin machine
(Fig. 503), which has been built since 1908 ; it is movable on a carriage a and a pair of
rails at the lower end of the hearth, so that the apparatus can be moved freely, and the
coke may be loaded in the rotation in which it is pressed. The conveyor b covers the
major portion of the hearth and reaches to the centre of the truck, the shorter section is
furnished with a weight to balance the longer end. The carriage a has a covered-in
driver’s stand with motor and countershaft, and is self-propelling. Although the coke
has to be lifted by the men with the forks a little higher than in the previously described
