NEW GLASS MOLDING MACHINE.

S. Kribs of New York has invented a new glass molding machine. A leading feature of this machine is the construction, which enables a double insulator to be formed, that is, an insulator carrying two wires so formed that a re-entrant cavity lies between the two wires, to prevent short circuiting the wires from sleet or rain. Another feature lies in the handling of a core used to mold threads on the interior of the insulator in such a manner as to prevent stripping the threads. An additional advantage lies in the arrangement of a plurality of molds and an equal number of plungers so that they all work successfully, giving time to cool the parts.
