Definitions

  • Our invention relates to electric incandescent lamps and to other similar devices which are to be connected in some convenient manner to a source of electrical energy. More particularly, our invention relates to the base or terminal portion of such devices which, when fitted into v an appropriate socket, completes the electric connection oi the device.
  • One object of our invention is to provide an extremely simple base which is both reliable and inexpensive.
  • Another object oi our invention is to provide a simple construction which allows the lamp or other device to be very conveniently inserted in a socket and removed therefrom.
  • Other features and advantages oi our invention will appear from the drawing and the description which follows of various species thereof.
  • Fig. i is a perspective view of an electric incandescent lamp comprising our invention
  • Fig. 2 is a vertical section therethrough and through a socket with the contact-making elements revolved so as to make them appear in the section
  • Fig. 3 is a perspective view of a socket
  • Figs. 4-. and 5 are perspective and vertical sectional views respectively of a modified form of our invention
  • Figs. 6 and i are corresponding views of another modification.
  • Figs. 1 and 2 The specific embodiment of our invention shown in Figs. 1 and 2 comprises a bulb 10 with the neck portion 11, which is cylindrical in shape and which is preferably provided "with a pair of longitudinal grooves 12 having protuberances 13 therein.
  • the rim of the bulb is sealed to an outward extending fiange it of stem 15 which is substantially perpendicular thereto, making a complete enclosure which is evacuated or gas filled as desired through tube 16.
  • This so-called tipless construction is disclosed in Mitchell and White Patent No. 1,423,956.
  • Electrical connection to the interior of the enclosure is made through leading-in wires 17 and 18, the inner ends of which are in this particular instance connected to respective ends of the filament 19.
  • the outer ends of said wires pass through disc at points preferably some distance from each other and at positions as near the fiange 14 as possible.
  • the disc 20 is an insulating member composed preferably of card board, hard rubber, asbestos or other similar and economical insulating sheet material and has a centrally located hole therein, through which the end of exhaust tube 16 protrudes and locates the disc correctly on flange it to which it may be glued or cemented.
  • the ends of the leading-in. wires 1'7, 18 extend through apertures in the disc 20 and the extreme outer ends thereof may be fashioned as by coiling into terminal contacts 21. These terminals are preferably located on portions of disc. 20 directly over fiange 14 which prevents their dislocation when the lamp is pushed into a socket.
  • a suitable socket is shown in Figs. 2 and 3 and comprises spring fingers 22. These are positioned and shaped to engage the-grooves 12 of the bulb neck and the protuberances 13 to hold the lamp securely with the terminal contacts 21 registering with the terminal fingers 2% of the socket.
  • the lamp is prevented from improper insertion by thefact that the spring fingers 22 are backed up by stop screws 23 which prevent the sufficient separation of said fingers to receive the portions 11 other than the said grooves.
  • FIGs. 4 and 5 A modification of our invention is shown in Figs. 4 and 5. This lamp differs from that above described in that the exhaust tube 25 is sealed ofi within the hollow interior of the stem to lessen the chance of its becoming broken and the tubular portion 26 of the stem is also enlarged so this operation may be more easily performed.
  • a modified form of base terminal is shown comprising globules of solder 2'? each attached to an end of a leading-in wire.
  • An electrical device consisting of a glass bulb and having a pair of lead wires sealed into and extending longitudinally from said bulb, terminals connected with said lead wires, and an insulating member firmly seated in the end of said bulb and serving to anchor said terminals, the adjacent end of said bulb being provided with a connected with said lead wires, and an. insulating member firmly seated in the end of said bulb and serving to anchor said terminals, the adjacent end of said bulb being provided with a groove definitely located with reference to said the ends of said lead wires, the said lead wire ends being bent over on the said flange of said stem to constitute terminals.
  • An electrical-device consisting of a glass bulb and having a pair of lead wires sealed into and extending longitudinally from said bulb, terminals connected with said lead wires, and an insulating memes disc firmly seated in the end of said bulb and serving to anchor said terminals, the adjacent end of said bulb being provided with means for preventing improper insertion of the said device in a socket.
  • An electrical device consisting of a glass bulb and having a pair of lead wires sealed into and extending longitudinally from said bulb, terminals connected with said lead wires, and an insulating disc firmly seated in the end of said bulb and having openings therein through which said lead wires extend to said terminals which are anchored by said disc, the adjacent end of said bulb being provided with means for preventing improper insertion of the said device in a socket.
