Abstract
Apparatus for glazing bases of electric bulbs comprising a number of combined tools on the circumference of a continuously rotating rotor, the combined tools consisting of coaxially arranged upper and lower parts, a mold being formed by the lower part. The apparatus includes means for feeding molten glass and for pressing it by the upper part, means for checking the presence of base sleeves and contacts at the working station, and means for removing excess glass in the course of the pressing operation. The apparatus includes means for ejecting a sleeve from the lower part of any tool which does not contain a contact, and means for preventing the feeding of glass to any tool which does not contain a sleeve.
Claims10
Apparatus for glazing the bases of electric bulbs, comprising a frame, a rotor supported on the frame for rotation about an axis, driving means for continuously rotating the rotor, a plurality of angularly spaced combined tools for glazing bases carried by the rotor along its circumference, each tool being composed of a first part and a second part aligned therewith, the first part of the tool comprising a punch mounted for reciprocation toward and away from the second part of the tool, the second part of the tool comprising receptacle means for receiving a sleeve and a contact for a base, means for feeding a contact to each of the receptacle means while the receptacle means is moving with the rotor;
- means for feeding a sleeve to each of the receptacle means containing a contact while such receptacle means is moving with the rotor and for assembling such sleeve with the contact, means for feeding molten glass to the interior of the sleeve thus assembled with the contact in the receptacle means, and means for thereafter thrusting a punch while moving with the rotor toward the second part of the tool to shape the glass deposited in the assembly.
