Definitions

  • the object of our invention is to-provide means which will insure that the lamps are inserted with the filaments properly disposed. Further features and advantages of our invention will appear from the description which follows 0 species thereof and from the accompanying drawing.
  • Fig. 1 is an elevation of one form of multiple filament lamp
  • Fig. 2 is an elevation at right angles thereto
  • Fig. 3 is an elevation of another form of lamp
  • Fig. 4 is a perspective of part of the mount of the lamp shown in Fi 1
  • Fig. 5 is a similar view of the mount 0 the lam of Fig. 3
  • Fig. 6 is a partial perspective 5 owing the lamp base and its socket
  • Fig. 7 is a bottom plan view of the base
  • Fig. 8 is athe lamp, its socket an the associated reflector
  • Fig. 9j is a diagrammatic view showing the electric circuits.
  • FIG. 1 to 5 inclusive are shown two forms of multiple filament incandescent lamps each of .which comprises three filaments.
  • the lamp comprises the usual bulb 10, base 11 and mount 12.
  • the filaments 13 and 14 are of highcandle power and are preferabl V- shaped and coiled.
  • the axis of the lam ulb is in the plane of and passes throng the vertex of the V-shaped filament 14.
  • the filament 13 is located in a plane substantially parallel to and at one side of that of the filament 14,
  • the filament 15 is a low candle powered filament which gives a parking light as distinguished from the driving li hts which are furnished by either of the otier filaments.
  • Conductor 16 is connected through the conductor support 16' to one end of the filament 13, the other end of said filament being connected to the conductor support- X which is mechanically and electrically connected to the conductor support19.
  • the conductor 17 is connected throu h conductor sup rt 17' to one end of the lament 14, and t e other end of said filament is connected to the conductor support 19'.
  • the conductor 18 is connected throu h conductor sup ort 18 to one end of the lament 15, the ot er end of said filament being connected electrically and mechanically to conductor support X.
  • the leading-in conductor 19 is therefore thecommon return wire and is connected to the shell of the base.
  • the other conductors 16, 17 and 18 are connected to the base contacts 20, 21 and 22 respectively shown in Fig. 7.
  • the driving filaments 13 and 14 are shown as located at opposite sides of the axis of the lamp.
  • the minor or arking filament 15 is located at one side 0 the filament 14.
  • the connections are shown in Fig. 5 and are similar to those shown in Fig. 4.
  • the base of the lamp comprises a shell having the two pro'ecting pins 23 and 24, which are diametrically opposite, and in 23 is somewhat closer to the outer end 0 the base than is'the pin 24. 'A
  • socket 25 is provided with slots 26 and 27, I
  • the former being adapted to receive the pin 23 and the other, the pin 24.
  • the slot'26 is consequently somewhat longer than the slot 27. This arrangement prevents improper insertion of the lamp in the socket. If it were attempted to invert the lamp, the pin 23 would strike the bottom of the slot 27 before the pin 24 would reach the bottom of slot 26 and it would therefore be impossible to turn the lam to cause the pins to enter the offset portions 26 and 27 and to lock the lamp in its socket.
  • Fig. 8 is shown the reflector 28 of the usual parabolic type and having the lamp socket 25 located centrally thereof.
  • the lamp shown in Figs. 1 and 2- is shown mounted in the said socket, and inasmuch as the filament located at the axis is lowermost,
  • this filament is located at the focus of the reflector.
  • the other filament 13 is above the focus.
  • this arrangement maybe uniformly secured.
  • Fig. 9 the electrical connections are shown diagrammatically.
  • Leading from one terminal of the battery 29 is conductor 30-connectedto switch 31 around which are disposed the'switch contacts 32, 33, 34, 35 and 36.
  • a conductor 37 extends from con-.
  • conductor 39 extends from contact 33 to the other high candle power filament 14 and back to ground 38 through conductor 19.
  • Conductor 40 extends from contact 34 to the low. candle power filament 15 which is con-v nected to ground 38 through common conductor 19.
  • Conductor ll connects the contact 35 to the conductor 39 and the conductor 42 connects contact 36 to conductor 37.
  • .parking filament 15 is illuminated; and when it is rotated so as to engage the contacts 35 and 36, both the high candle power filaments 13 and 14 are illuminated in parallel.
  • a projection lamp the combination of an incandescent lamp having a base and a plurality offilaments, a socket adapted to receive said base, the base of said lamp having pins projecting laterally therefrom from diametrically opposite points in the periphery thereof and disposed at diflerent distances from the outer end of said base andlthe socket being provided with corresponding longitudinal slots of different lengths to receive said pins.
  • a projecting lamp the combination of an incandescent lamp having a base and ,a plurality of filaments located differently with respectto the axis of said incandescent lamp and a socket therefor, the base of said lamp having pins projecting laterally therefrom from diametrically opposite sides thereofiand disposed at different distances from the-outer vend of said base and the socket being provided with corresponding longitudinal slots of different lengths to re- .ceive said pins.
