APPARATUS FOR CHARGING TELTDXG SVIETLTNG FURNACES.
Application lec February 29, 1928, Serial No. 257,988, and in Germany February 28, 1927.
The method usually adopted for charging tilting smelting furnaces, more particularly electric furnaces, is to pass in a chute, filled with the material to be fed to the furnace, through the furnace door by means of a special crane or hoisting gear, then to place the chute at such an angle'that the charge slides .down into the furnace, and, in order to increase the angle of discharge 'of the chute the furnace is tilted.
According to the invention the chute is connected to the furnace` in such manner that the tilting of the furnace causes the chute to discharge its load into he furnace.
rllhe invention is ,diagrammatically illustrated by Way of example in the accompanying drawings.
Figure 1 illustrates the whole apparatus, and
Figure@ shows a detail View. rlhe electric furnace a is supported upon the rollers so as to be tiltable. The electrodes c, which are in an elevated position, have the clamps (l by which they-are carried, connected to the furnace a in known manner. rlwo hooks f are fixed one on each side of the furnace opening e, through which the charge is introduced, and above the middle of the door a jib his attached to the pillar g and carries at its other end the hook i. rlhe open, forward end of the chute 7c on 'a truck Z is advanced by Way of example through the opening of the door, so that the pin m attached to the closed end of the chute comes into a position above the hook i, while theends of the pins 11, projecting at cach side of the chute come into a position above the hooksv If the discharge lip 0 is pressed down, the hooks fengage under the ends of the pins n, and the hook i under the pin m, and the chute takes part in the tipping movement, that is, it is brought into theposition shown in dotted lines in Figure l, so that the material slides into the furnace.
ln order to spread the charge out in the furnace it is advantageous to attach the pin l fn, to the chute lc so that it may rotate about a vertical shaft fp as shown in Figure 2 and to mount the jib l?, so as to rotate about the pillar g;
l claim:
