Addendum to patents Λί 79993 from September 21, 1893.

Patented in the German Empire on February 3, 1895. Longest duration: September 20, 1908.

In the device described in patent no. 79993 an inclined pan or channel c is used, which can be displaced in two directions and into which the liquid iron is poured out by means of a pan α.

In order to avoid this ladle and to feed the liquid iron directly from the cupola furnace for atomization, according to the present invention the channel c of the main patent is extended to the cupola furnace (Fig. 2).

The attachment a, with which it is fixed to the wedge, is made round, and a clamp with a chain attached to the front part of the channel, which is connected to a winch. "When the liquid material flows from the opening b of the cupola into the channel c, the operator turns the crank k and thereby approaches the channel to the horizontal position.

With this pendulum motion he is able to move the outflow of the iron as desired to be regulated, irrespective of whether it flows out of the cupola in large or small quantities, which is extremely important for the production of uniform balls.

The displaceability of the channel c or the steam pipe e in two directions remains in this arrangement exactly as indicated in the main patent.

With the device described above it is necessary that the cupola is very close to the pouring device, because otherwise the channel c would be too large and unwieldy. The arrangement described in FIG. 1 is determined for this case.

In the same, the adjustable channel c of the main patent is retained in its known construction and the extension ^{channel c 1 is} extra mounted in the bracket d with two pins.

By means of the spur gears e and y and crank g it now receives the above-mentioned pendulum motion and therefore effects in the same way the regulation of the liquid iron fed directly from the cupola furnace.

It is also easy to give this auxiliary channel c ¹ the adjustment in two directions with respect to the steam pipe e, so that the channel c can be omitted. For this purpose, the bracket d is provided with a round shoulder h and thread and inserted into a bearing bush i.

■ By turning the handwheel m , the height is adjusted, while the channel itself moves slightly around the pin h , thus shifting the discharge to the side. The shift forwards or backwards is effected by the handwheel / with spindle η , which moves the bushing i along with the channel c forwards and backwards.

For operational reasons, however, it is preferable to keep the channel c of the main patent with displacement and the channel c ¹

Claims (1)

to impart only a pendulum motion. On the other hand, it is easy to move the pendulum mechanism from the center of the channel c ¹ outwards, either after the furnace to or after the pipe e. In the latter case, as shown in Fig drawn dotted ι., Under the channel c ¹ b at a base /? ' appropriate. At its other end, the channel c ^{1 is} pushed into the clamp η and can be set in a more or less inclined position by means of the winch mechanism α described above or by another lifting device that also acts from below. Patent claims: i. An embodiment of the device patented under No. 79993, characterized in that the inclined pan or channel c receives a pendulum movement, which pan remains displaceable in two directions, for the purpose of regulating the liquid iron fed directly from the cupola furnace.
An embodiment of the. Device contained in claim 1, characterized in that the channel is divided in such a way - that one in c remains in the manner of the main patent, while the second half of any length c ¹ creates the connection between the CupoLofen and the channel c , whereby it is set in oscillating motion by known means.
An embodiment of the device contained in claim 2, characterized in that the separately oscillating channel c ^l is made adjustable in two directions in order to achieve the same effect as indicated in the main patent when the channel c is omitted. 1 sheet of drawings.
