Definitions

  • This invention relates to hermetically closed devices, such as electric incandescent lamps, X-ray tubes, three electrode tubes and like electric bulb apparatus, of that type which may be reclaimed or regenerated, by which is meant devices which may be opened up by means of a readily fusible joint so that the filament may be renewed after burning out or breakage thus obviating the throwing to waste of the remaining valuable undamaged parts of the device.
  • the object of the invention is to provide an improved, simple and less expensive device of the aforesaid type in which it has been the custom in the past to form the bulb by the usual blow-pipe method and then secure the same with cement or some other adhesive to a met- 7 al base by which the device could be secured in its electrically connected socket.
  • Fig. 1 is a view of a lamp bulb partly in section with the bulb, cover, and joint ring separated.
  • Fig. 2 shows a finished lamp.
  • Fig. 2a is a similar view partly in section.
  • Fig. 3 is a plan view of Fig. 1.
  • Fig. 4 is an enlarged sectional view showing the globe and cover assembled.
  • Figs. 567 and 8 are detail views of the electric contacts in section and plan.
  • the lamp consists of a bulb 1 made of glass and cut across and smoothed by grinding on the line X-X.
  • the reference numeral 2 indicates a ring of glass or the like, the inside diameter of which approximates that of the mount of the bulb, the fusing point of this ring being much lower than that of the parts 1 and 3, although its coefficient of expansion is about the same.
  • the cover 3 constitutes the base of the lamp in which the wires 14 and 18 entering the lamp are fused, and itself forms a socket connection for the lamp.
  • the rod 4 as shown is intended for use when a metal filament is employed, and may be dispensed with when the filament is of carbon.
  • the said cover is to serve as a screw base, it is provided with two metal contacts 12 and 13 embedded in the glass and formed respectively as shown in Figs. 6 and 8.
  • the contact 13 makes the electric connection between the wire 14 and the screw threaded base, the
  • the lamp When the three parts, 1- 2 and 3 of the lamp are manufactured, and the filaments are positioned the lamp may be completed by melting the ring 2 thereby connecting the said three parts and then producing a vacuum in the bulb.
  • I claim 1 A process for making an electric hermetically closed vessel, comprising the steps the mass, mounting a filament on the filament supporting mealns of the head, and in electrical connection with said leading-in wires and contacts, and uniting the blown bulb and moulded head by means of a vitreous 'oint of greater fusibility than either of sai parts, and in such manner that said head closes the open end of the bulb, the air content of the device being treated as required.
  • a process of forming a hermetically closed vessel of the class described consistin in blowing a glass bulb with an open en moulding under pressure a solid glass head with integral socket-engaging projections and filament supporting means, and simultaneously embed in therein the elect'ric current connections the filament system of the device and mounting a filament thereon, uniting the open end of the blown bulb to the cor responding part of the moulded head by a ring of glass with a lower fusing point than the glass of either the bulb or head, the whole being welded together by subjecting the assemb ed parts to-a temperature that will fuse the ring without fusing the parts to be connected and evacuating the bulb.
  • An evacuated electric hermetically closed vessel comprising a glass bulb having an open end, a solid glass head havin a coeflicient of expansion different from t at of the said bulb, and comprising integral socketengaging projections and a filament supportin means, electric current connections embedded in said head, a filament mounted upon the filament supporting means, and a separate rin of glass of greater fusibility than that of t e head and bulb which unites these two parts so as to close the vessel.
  • a hermetically closed vessel comprising a unitary head of massive vitreous material and forming the sole direct means of attachment of the device to a supporting socket and also having a filament supporting stem integral therewith, a filament system with contacts and leading-in wires embedded in said head, an open ended glass bulb havin a coefiicient of expansion different from t at of the said head, and a separate fusible glass ring which unites the head and bulb to complete the closure of the device.
  • a hermetically closed vessel comprising a unitary head of massive vitreous material with external screw threads whereby the head forms the sole means of attachment of the device to a supporting socket and also having a filament supporting stem integral therean integral rim formed u said head, external means upon said cad whereby the latter forms the direct means of attachment of the device to a suppo socket, a filament supportin stem integra with saidhead, afilament, and eadin -iu wireaha their entire length except 51c portions bulb embedded hermetically in the man of the.
  • open-ended glass bulb having a coefiicient of expansion difierent from that of said head, and a separate fusible glass ring which unites the head and bulb to complete the closure of the device.
