[Also in Group XII] In a melting unit for use in conjunction with type-composing machines or for melting stereotype metal, the interior of the unit is divided by a heat-resisting or heated separating wall c into two chambers a, b, the chamber a being provided with a draw-off valve 2 and constituting a working chamber, whilst the other chamber b constitutes a melting chamber. The melting unit delivers the metal to a mould for producing the ingots to be fed into the built-in mould of a type-composing machine or to a stereotype matrix. The two chambers are interconnected by conduits 3 for feeding molten metal from the melting chamber into the working chamber and the chamber a is provided with a thermostatically controlled heater 5 independent of a thermostatically controlled heater 6 in the chamber b. The temperature in the chamber a is controlled at about 290‹ C. and that in the chamber b at about 270‹ C. The chamber a is provided with a hinged cover 8 and a motoroperated stirring device 14. The wall c may be filled with heat-resisting material 4 or may include a heater under the control of the thermostat which controls the working chamber a heating device, Fig. 3 (not shown).
