Abstract
Apparatus for removing a fused silica glass object from a rotating pot has a gripping member which grips the upper rim of the fused silica glass object and a rotational synchronization member connected to the gripping member which is lowered vertically into frictional contact with the rotating pot. The rotation of the pot drives the rotation of the synchronization member which drives the rotation of the gripping member. The object can be withdrawn vertically from the pot without the angular velocities of the object and pot diverging.
Claims14
An apparatus for removing a fused silica glass object from a rotating pot containing pulverulent refractory material therein, comprising:
- a rotating pot for containing a fused silica glass object;
- a gripping member having means for gripping the upper rim of the object for removing said object from said rotating pot, said member capable of moving vertically while rotating and while gripping said object;
- a rotational synchronization member operatively associated with the gripping member and located so as to provide frictional contact between said member and the edge of the pot containing said object while said pot and said object are rotating;
- and
- means for moving said gripping member vertically downward and upward the upward movement removing said object from said pot
- said rotational synchronization member being located with respect to said pot so as to impart to said gripping member the rotation of the pot when said rotational synchronization member is moved into frictional contact with the pot.
An apparatus for removing a fused silica glass object from a rotating pot containing pulverulent refractory material therein, comprising:
- a rotating pot for containing a fused silica glass object;
- a gripping member for contacting the upper rim of said object to remove said object from said pot, said member capable of rotation and vertical movement towards and away from said pot while rotating and while gripping said object;
- a rotational synchronization member operatively associated with the gripping member and located for axially aligning said gripping member with said object and said pot while said pot and said object are rotating, and for imparting the rotation of the pot to the gripping member while said rotational synchronization member is in frictional contact with the pot;
- and
- means for vertically moving said gripping member toward and away from said pot while said gripping member is rotating the away movement removing said object from said pot
