Abstract
This invention relates to a fusion and casting machine for the preparation of glass buttons for analysis. The machine contains an assembly of several heaters which moves with a precession motion imparting agitation to the content of the molten materials. When the materials are fused, agitation stops, flame goes out, moulds which were intially above the crucibles move under the crucibles, and the crucibles turn over and transfer their content into the moulds where solidification takes place. Perfect glass buttons are produced: these are stable, homogeneous, flat, smooth, bubble-free and need no further processing before the anaylsis.
Claims6
A machine for making glass buttons, comprising:
- a base (9);
- an upstanding column (2) pivoted at a pivot joint (6, 7, 8) adjacent its lower end to said base for universal lateral tilting movement;
- drive means (11) below said pivot joint for swinging the lower end of said column in substantially circular motion;
- a normally upright crucible (17) for a charge to be melted carried by the upper end of said column for tilting about a horizontal axis;
- a mold (18) for receiving a molten charge and means (20 and 22) on said column holding said mold in inverted position over said crucible and mounting said mold for pivotal movement about said horizontal axis;
- heater means (1) on said column arranged to heat said crucible and mold simultaneously;
- means (21, 28) for rotating said mold about said horizontal axis and lost motion means (43) between said crucible and mold for tilting said crucible about said horizontal axis after a predetermined degree of tilt of said mold;
- and
- means (14) for rendering said drive means inoperative when said mold and crucible are being rotated about their respective axes.
