' 12 Claims. (Cl.176--32)" The present invention relates to an incandescent electric lamp in whichthe lamp base can be readily and easily inserted in or removed from electric socket of standard orspecial design, and,
to hold the lamp base firmly in the lamp socket. The lamp base. is constructed of substances of a high resistance for electric current,.reducing the heating of the lamp base toa minimum.
The base of the lamp is so constructed that itwill fit any standard or special designed lamp terial as lamp base, and'in construction is molded ment to lamp base are separated by partition over and snuglyiit the basal endof lamp bulb. Lugs inlamp base spacing the notches snugly-fit into slots in the basal end of the. lamp bulb so When thelamp base is pushed into an electric socket it is firmly held by side wall pressure automatically forcing connections together of the lamp bulb base and the electric socket.
We do not limit ourselves as to the style, design, or construction of fastening contact points on thebase of the lamp to connect leading-in wires fromthe lamp bulb. so as to secure connection from lamp bulb leading-in wires to the electric socket,
I In the drawings annexed hereto and forming a part hereof: Fig.1 represents a side view in vertical section of an incandescent electric lamp with our invention embeddedtherein in the constructionoi a new and improved incandescent electric lamp. Fig. 2 is a top view of base as shown inFig. 1. In Figs. 3 to 5 inclusive is shown detail views of a similar construction. In Figs. 6 to 8 inclusive is shown detail views of another dea with lamp base. Lead-in wires from lamp filathat the lamp. basewill not turn on basal end of lamp bulb'but is interlocked therewith. The lamp bulb may be constructed with lugs to snugly fit in sulci in the notch or notches in lamp base so that lamp base will not twist on basal end of lamp bulb. Y
sign or variance in construction. In Figs. 9 to 12 inclusiveis shown another modified construction.
In Figs. 13 to 15 inclusive is shown still another of a soft non-conductor substance. Lamp base I, push-in type, maybe constructed of any suitable substance and actsas an insulator for connecting wires l and 5-from the lamp fllamentto the electric socket. Wire 4 connects electrical contact-'2 and'lamp filament, acting as oneof the contacts between lamp base Land the electric v socket. Wire 5 connects electrical contact 3 and lamp filament completing 'thecircuit and contact to the electric socket in connection with electrical contact 2. By entering lamp base I into 1 A metal ring is used in. one modification with sulci on its inner surface to connect and snugly;
ilt lugs on the basal end of the'lamp bulb and with lugs on its outer surface to snugly ilt-sulci in notch or notches of lamp base so that lamp base will notrevolveon basal end of lamp bulb. Metal ring l5 may be .cast'or sweat on basal end of lamp bulb.
Lead wires are secured to metal contact points or contact projections by a drop of solder apelectric socket a complete circuit is formed by and through electrical contacts 2 and 3 connected by wires 4 and 5 tolamp filament in lamp bulb 6.
, Wire 5 connects lamp filamentto electrical contract 3 through groove 1 in base I. Partition wall 8 is part of base I and is made of the-same nonconductcr substance as base I. I
Arcuate lug H, as shown in Figures l-2, operates as a broken thread to engagethe female member of the-socket of the customary electric light socket.
In Figs. 3 to 5 inclusive a similarconstruction. of incandescent electric lamp is shown. The only variance from Fig. l is lamp base I a and contact projection 3a. There is a circular discontinuous groove 9 separated into a plurality of sections by partitions III that are shown as four in number but more may be used if so desired to Slip into basal end of the lamb bulb cement lamp baseto the lamb-bulb.
and snugly fit slots ii in lamp bulb base I! (Fig. 3),securely attaching base la to lamp bulb 3 shown in Fig. 1, so that base is will not turn-on lamp bulb base l2. Partition wall I acts as a nonconductor between wires 4 and 5.
In Figs. 9 to 12 inclusive wire from lamp filament to electrical contact 3b} passes through side wall of lamp base lc. Sulci 13 consisting of one or more in notch 9 slip over and snugly fit lugs ll'on metal ring it, lugs ltjon lamp bulb base Ha are pressed into and snugly fit metal ring it.
In Figs. 13 to 15 inclusive sulci ll, consisting substance, a separate notched metal securely attached to the basal end oi. the lamp bulb; the resilient compressible cap having a thin wall partition of electrical non-conductor substance,
the resilient. compressible cap -"having sulci in notches to slip over and snugly fit the metal ring holding the lamp base to the lamp bulb without cementation.
