2. The combination of rotary inwardlymovable former-sections, and a spring-backed support or head contained Within the same and adapted to receive the glass article and I 5 to permit it to be inserted gradually Within the closing sections; substantially as described.

In testimony whereof I have hereunto set my hand.
