Abstract
241,189. Naamlooze Vennootschap Internationaal Octrooibureau. Oct. 10, 1924, [Convention date]. Shaping glassware after formation.-Relates to a method of separating hollow glass articles, particularly electric lamp bulbs, from the surplus neck portions to which they are attached after removal from the blowing-mould. According to the invention, separation is effected by means of a gas flame, applied to the interior of the neck of a bulb, which melts through the glass and prevents the rim of the finished bulb from flanging inwards. The bulb 49 is shown held by a ring mould 11 a number of which are mounted on a table 81 forming part of an automatic bulbblowing machine, means being provided for rotating the mould at appropriate times. The upper edge of the neck of the bulb is held 'between spring-operated grippers 33 and the lower edge of a cylindrical member 11<a>. A burner 5, having a ring of jets 10 and to which gas and compressed air or oxygen is supplied through tubes 6, 7, is movable vertically through a guide sleeve 3. In order to sever the bulb from the surplus neck portion or " lost head," the burner is lowered through the ring mould, which is in rotation, and flames from the jets 10 fuse through the glass along a narrow circumferential zone. The pressure of the flames also prevents the fused rim, which forms the edge of the finished bulb, from flanging inwards. During this operation, the bulb is supported, and centred. The supporting-device consists of a seat 55 looselv mounted on a shaft 53 which is movable vertically and is rotated in unison with the ring mould. A frame 66, pivoted on the upper end of the shaft 53, carries rollers which centre the bulb. When the neck of the bulb is fused, the frame is lowered and the bulb detaches itself from the " lost head." At the same time, a bifurcated lever 73, operated by the movement of the frame, is turned about its pivot 74 and removes the bulb from the machine.
