  • Patent number: 7481323
    Abstract: A rack for hingedly mounting at least one door has a lower mounting plate and an upper mounting plate which are jointed by a central, telescoping support shaft. A plurality of mounting apertures are formed, equally distanced from the center of each of the upper and lower mounting plates which receive the pins of upper and lower attachment brackets which are attached to the upper and lower surface of each door to be mounted. When mounted, each door may be pivoted about the upper and lower attachment brackets so it may be painted on each of its two sides without interfering with any other door mounted on the rack. The rack may be adjusted to receive over height doors, as well as standard doors.

  • Patent number: 4457494
    Abstract: A refractory lined melting furnace particularly suited for separation of non-ferrous metals with embedded or attached ferrous components, includes a casing or body pivotally mounted and tiltable by means of fluid operators. The interior is divided by two vertical walls into a combustible waste burning portion for the generation of combustible gases to assist in heating the furnace, and a melt chamber into which a variety of metallic waste can be charged for melting. A conventional fire burner is supplied to the melt chamber. The temperature of the melt chamber is raised to the melting point of the metallic waste material having the lowest melting point, e.g. aluminum, and when the aluminum is melted, the aluminum runs through drainage apertures into a liquid metal holding chamber provided on the floor of the melt chamber. When the molten metal has drained, the furnace is tilted rearwardly to discharge the remaining scrap out through rake-out doors at the rear of the melt chamber.
