METALLIC CORE OR REINFORCE FOR CASTINGS.
Specification of Letters Patent.
Patented June 24, 1913.
Application filed February 16, 1912. Serial No. 678,132.
T 0 all whom it may concern:
Be it known that I, I'IEINRICH Sonorrnxnn, a subject of the Emperor of Germany, residing at No. 8 Krebsstreet, Voelklingen-on-the-Saar, Rhineland, Germany, have invented a certain new and useful Improvement in Metallic Cores or Reinforces for Castings, of which the following is a specification, reference being had therein to the accompanying drawing.
The present invention has for its object the strengthening of castings and consists in a filling, core or wrought metallic rein-- force inserted in a cast body, to strengthen it.
The invention consists in a wire-like flexible twisted metal core comprising a plurality of members, some of which may be hollow, or so spaced as to form channels or passages between them, thus producing an outlet for the gases in the mold. Both ends of the coil need not be inserted; in the molten metal, in this way the wires will yield more readily to expansion caused by heat.
In order to obtain a casting containing no bubbles the invention will be found of advantage; as the air in the mold is displaced by the incoming molten metal and the outer wires will adhere to the cast body, while the inner wires will remain movable. The wires being wound spirally in opposite directions, the necessary expansion and contraction is obtained.
In the accompanying drawings, which form part of this specification :Figure 1 is a plan View of the core or filling detached, and Fig. 2 is a like View showing the core in a mold surrounded by one part of a flask.
The core or reinforce is composed of several wires a Z) which are twisted or coiled together, and may be made smaller at their extremities or ends. The wires may be of any shape found to be most practical, or the same may be hollow as shown at o. The coils may be wound around a stick which will be withdrawn as soon as the wires have been wound together, whereby a channel will be formed in the center of the core. Several layers of wires may be wound whereby the twist or torsion may be changed, these changes of construction will greatly strengthen the core. The core may be heated before being inserted in a mold in any preferred manner, however the heating is not essential, as in cooling the cast metal, the wire core will yield to any expansion or contraction.
In practising my invention, the core a is laid in the sand f properly anchored therein in the manner of anchoring sand cores, and when the metal 6 is poured into the mold contained in the flask (Z, the core or reinforce becomes thoroughly embedded therein and by the nature of the metal of which it is made adds greatly to the strength of the casting.
In pouring the molten metal, air contained in the mold and displaced by the metal flows along the channels between the wires 6 and escapes through the usual vent in the mold.
Having thus fully described my inven tion, what I claim is:
1. A metallic core or reinforce for castings consisting of groups of members wound spirally in opposite directions, the outer group being concentric to the inner group and adapted to be embedded in the molten metal while the inner group remains free.
2. A metallic core or reinforce for eastings consisting of groups of tubular members wound spirally in opposite directions the outer group being concentric to the inner group, forming channels for the escape of gases from the mold, and said outer group being adapted to be embedded in the molten metal, while the inner group re mains free.
In testimony whereof I affix my signature in the presence of two witnesses.
