Abstract
A molten metal sampler that is provided with a chamber that can be evacuated and is adapted to hold the vacuum until it is to be placed in operation. When the sampler is contacted by the molten metal, a seal holding the vacuum will disintegrate to permit passage of the molten metal into the evacuated chamber.
Claims16
In a molten metal sampler;
- a container adapted to be mounted at the end of a probe;
- a mold in said container for receiving the sample of molten metal;
- means permitting the flow of air between the interior of said mold and said container but preventing the flow of molten metal out of said mold;
- air tight sealing means for sealing said container so that the atmosphere can be evacuated from said container as well as from the mold in said container and the vacuum can be maintained therein;
- and filler means for admitting molten metal into said mold while the mold is in said container and while the vacuum is maintained in said container for assisting the flow of molten metal into said mold.

In a molten metal sampler;
- a support;
- a container fixedly supported in said cylinder;
- a mold in said container for receiving the metal that is to be sampled;
- a filler tube in communication with said mold and extending through said container to form a passage for the molten metal to flow into said mold;
- a heat sensitive seal on said filler tube which seals the tube at ambient temperatures but melts when subjected to the heat of the molten metal to admit the flow of molten metal through said filler tube;
- and evacuating means carried by said support operable to create a vacuum in said container for evacuating the atmosphere from said container and thereby the mold in said container for assisting the flow of molten into said mold and producing a high quality sample.
