Abstract
Abstract A diverter trough is slidably mounted below the known slide gate which controls the stream from a holding vessel with a bottom teeming outlet. A hole through the trough permits normal teeming to proceed when the trough is advanced to pouring position. When the stream is restricted or shut off by the freezing of metal in the gate nozzle, an oxygen lance carried by the trough may be aligned with the nozzle to open it. If this cannot be achieved, the trough is retracted to intercept the descending stream of metal and divert the flow to an emergency collecting system. The trough also has an argon-supply pipe for sweeping away ''''bugs'''' from it while maintaining a protective atmosphere. The hole in the trough for normal teeming may be omitted. In that case, the trough is normally fully retracted to an out of the way position during such teeming.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
71 words
In metal-teeming apparatus including a holding vessel having a bottom outlet and a sliding gate to control the stream therefrom, the combination therewith of a diverter trough slidable below said gate, said trough being effective, when in diverting position, to intercept said stream and discharge metal laterally of said outlet, and power means for actuating said trough longitudinally, said trough having passages therein discharging jets of gas transversely of said stream.
Claim 2
Dependent Claim
71 words
In metal-teeming apparatus including a holding vessel having a bottom outlet and a sliding gate to control the stream therefrom, the combination therewith of a diverter trough slidable below said gate, said trough being effective, when in diverting position, to intercept said stream and discharge metal laterally of said outlet, and power means for actuating said trough longitudinally, said trough having passages therein discharging jets of gas transversely of said stream.
Claim 3
Dependent Claim
85 words
In metal-teeming apparatus including a holding vessel having a bottom outlet and a sliding gate to control the stream therefrom, the combination therewith of a diverter trough slidable below said gate, said trough being effective, when in diverting position, to intercept said stream and discharge metal laterally of said outlet, and power means for actuating said trough longitudinally, said trough having a passage for oxidizing gas extending upwardly therefrom, whereby a jet of gas may be discharged toward said gate by suitably positioning said trough.
Claim 4
Dependent Claim
85 words
In metal-teeming apparatus including a holding vessel having a bottom outlet and a sliding gate to control the stream therefrom, the combination therewith of a diverter trough slidable below said gate, said trough being effective, when in diverting position, to intercept said stream and discharge metal laterally of said outlet, and power means for actuating said trough longitudinally, said trough having a passage for oxidizing gas extending upwardly therefrom, whereby a jet of gas may be discharged toward said gate by suitably positioning said trough.
Claim 5
Dependent Claim
78 words
In metal-teeming apparatus including a holding vessel having a bottom outlet and a sliding gate to control the stream therefrom, the combination therewith of a diverter trough slidable below said gate, said trough being effective, when in diverting position, to intercept said stream and discharge metal laterally of said outlet, and power means for actuating said trough longitudinally, said trough having a hole therein whereby, on alignment of the hole with said outlet, normal pouring takes place therethrough.
Claim 6
Dependent Claim
78 words
In metal-teeming apparatus including a holding vessel having a bottom outlet and a sliding gate to control the stream therefrom, the combination therewith of a diverter trough slidable below said gate, said trough being effective, when in diverting position, to intercept said stream and discharge metal laterally of said outlet, and power means for actuating said trough longitudinally, said trough having a hole therein whereby, on alignment of the hole with said outlet, normal pouring takes place therethrough.
Claim 7
Dependent Claim
18 words
Apparatus as defined in claim 3 characterized by a releasable joint between said power means and the trough.
Claim 8
Dependent Claim
17 words
Apparatus as defined in claim 4, characterized by a spacer sleeve between said joint and the trough.
Claim 9
Dependent Claim
21 words
Apparatus as defined in claim 3, characterized by said power means being a fluid-pressure cylinder and piston suspended from said vessel.
