To aZZ whom it may concern.-
Be it known that I, CARL Aucnsr CAS- PERSSON, a subject ofthe King of Sweden, residing at Forsbacka, in the Kingdom of Sweden, have invented new and useful Improvements in Apparatus for Pouring and Casting Iron, Steel, and other Metals, of which the following is a specification.
The object of this invention is to procure in the manufacture of iron and steel solid in gois and castings free from blow-holes; but the apparatus can also be applied in the casting of other metals which are liable to get blowholes. In order to obtain this, I contrive that the stream of metal falling into the mold be divided into a great number of small streams, by which means the gases contained in the metal are enabled to escape, which gases 0th erwise originate unsound ingots and castings. I use for this purpose a vessel, furnished with openings in the bottom, which I call a colan tier-funnel, into which the metal is gradually run, either from the furnace or crucible itself, or from a ladle, and from this colamler-tunnel the metal then runs down in fine streams into the mold, which is placed underneath. The finer the perforations in the colander-funnel the better will be the resultobtained, pro vided always that the perforations are not so small that they become clogged up by the 1 metal under treatment. The accompanying drawings represent the apparatus used in the case of in got-molds which are filled from a bove. Figure 1 shows a colander-funnel in vertical section placed over an in gotmold. Fi 2 shows the colander-funnel as seen from above.
A is the colander-funnel, which consists of a vessel of sheet-iron, lined inside with firebrick or with a mass of some refractory sub stance, and perforated in the bottom with fine opemn gs.
1-3 is part of the handle for manipulating the colander-funnel.
G is a part of the ingot-mold,and D a plate which is laid on the top of the mold and fits close to the same. In this covering-plate are two openings-the one at E for the colanderfunnel, and the other at F for letting out the air and gases set free during pourin A covering-plate, D, is first placed over the opening for the pouring in of the metal, and
on this is placed a suitable colander-fuimel,-
, provided with openings, placed over the open- 1 ing of the mold and around the funnel, substantially as and for the purpose set forth.
In testimony whereofI aitix my signature in presence of two witnesses.
