The new closing device can then be moved upwards by means of the second hoisting mechanism and introduced into the emptied chamber, so that after operating the said locking device, the chamber is again ready for working. Fig. 1 is a side elevation of the apparatus, some of the parts being shown in section on the line A—B of fig. 2. Figs. 5 to 7 show various positions of the auxiliary truck travelling on the truck shown in fig. 1. (Six claims.) NEW PATENTS CONNECTED WITH THE COAL AND IRON TRADES. Applications for Patents. 8699.
