What I claim is: y 5 apparatus for molding metal compr1smg a reservoir member adapted to be seated in the upper end of a mold, the sides of said member being constructed of Wood, and lined on its interior with thin metal, a m bottom supported on the interior of the reservoir with holes therein, the reservoir being suiiiciently small to leave vents between the exterior of the reservoir and the interior of the top of the mold for the escape of gases. 2. An apparatus for moldin metal comprising a reservoir member aapted to be seated in the upper end of a mold, said reservoir member comprising a wooden casing with lugs on-its exterior on which the 29 reservoir rests, and an interior lining of thin vmetal extending under the wooden casing the reservoir being sufficiently small to leave vents between the interior of the top of the mold and the exterior of the sides of the reservoir, said reservoir having a bottom of refractory material with holes therein, said bottom being supported near the bottom of the reservoir.

3. An apparatus for moldin metal, in- '30 cluding a reservoir member a apted to be seated on the upper end of a mold, said member being constructed of inflammable material interiorly lined with thin metal said lining projecting inwardly to form a ledge, and a bottom for the reservoir having holes therein, said bottom being supported by said ledge in the reservoir.

In testimony whereof I aiix my signature. 1 ANDREW REED ROVVE.
