PORTABLE ELECTRIC LAM-P.

Application filedNovember 15, 1926. Serial No. 148,384.

My invention relatesto improvements in portable electric lamps, and has for its primary object a lamp intended for use on automobiles in which an electric light bulb is used and which bulb is protected in such a way by means of a cage so that the, bulb will be reasonably safeguarded against heavy base so that the same will stand up right andnot be liable to upsetting, the base being provided with an electro-magnet which is thrown incircuit at the same time that the bulb is illuminated so that the lamp will adhere in anyposition to any material which will respond to magnetic action. This renders my device especially applicable to autoadhere at practically any place or at least I any metallic part of the automobile so that road-side repairs, such as tire changing and the like and also adjustments to the engine underneath the hood, can be readily made and without the danger of fire.

In the drawings:

Fig. 1 is a side elevation of my device.

Fig. 2 is a top plan view of the same with the bulb removed;

Fig. 3 is a top plan view of Fig. 2 with the cage moved away so that a bulb can be placed in position; and

Fig. 1 is a vertical section taken on the line H of Fig. 1.

In the construction of my device, I employ a metallic base 5. This base is hollow and contains an electro-magnet 6. This electromagnet is of the usual construction and has the central magnetic core 7. Resting on the base 5 is a disk of insulating material 8, which carries electric contacts 9 and 10. The base and electro-magnet are secured to gether by means of a screw 11. Secured on top of the base 5 is a cylindrical member 12, which isprovided with a concentric cylindrical portion 13. This portion is of lessdi than the cylindrical portion 12 The mobiles because, as aforesaid, the lamp will cylindrical portion 13 carries a lamp socket .1 1 which is of the usualbayonet joint'type common to automobile light sockets.

Carriedbythe reduced portion 13 are; a plurality of guard members 15,16 and 17, which are substantiallyof U shape and which form protecting cage forlthe bulb 18. The member 15 is-provided with an outwardly bent portion. 19, and the member 17 with an inwardly bent portion 20. The

members 15, 16 and 17. have portions 21 passing through the cylindrical portion 13, the ends of these portions 21 being upturned jasindicated by the numeral 22 so that the same are lockedin position in the cylindrical projection 13, and, by means of the recess 2O orinwardly bent portion and the outwardly" bent portion 19, the members 15, 16

and 17 can be assembled into a rigid cage as illustrated in Figs. 1 and 2 completely surrounding the bulb so that in the event that the fixture. should drop, the bulb will be protected against ibreakagel' 1' The cy1'in drical housing 12 is secured to the basev 5 by means of screws 23. The housing 12 is also provided with an opening through which electric conductors 2 1 and 25 pass.

These conductors are secured to binding posts 26 and 27, which connect the. conductors to the contacts'9 and 10! The binding posts also carry electric conductors 28 and 29, which complete the'circuit through the electro-magnet. It is to be understood, of course, that the free end of the conductors 2 1 and 25 are provided with suitable means so that they can be readily attached to a source of electrical energy. It is further to be understood that while I have shown thebulb 18 as being of the double contact type, and I may, without departing from the spirit of my invention use the single contact, this however falls within the skill of any electrical mechanic and therefore is not shown or described, the Q essential feature of my device being to provide a portable electric lamp, which can be readily attached to and detached from v'a-' rious metallic parts of an automobile so as to serve as a trouble light, its use not being restricted only to making repairs but also in the event of the failure of'a tail light or one of the headlights since the electro-magnet made strong enough. to hold the light iii) Without removing the cage from the eye lindrical member so that a bulb can be readily inserted and without loosening any nuts or screws which secure the cage in position.

It i will be observed from my foregoing description that the cage as made by me is a knocked-down cage and that itcan be knocked down andre-asse nbled Without removing the cage from the base or from. the cylindrical member. s

' Having fully described my invention,

What I claim is ,1; A portable electricv lamp comprisinga hollow, base, a cylindrical member Carried by said base, an electric lamp socket'secured within said member, a plurality of members haVing -inturnedends pivotally secured at both, ends in the u'pper end of said cjflindrical member, said members adapted to be swung outward for affording free access to said socket for the insertion of abulb and toward each other for forming a protectingcage for said bulb, and; means for detachably holding said members. together when forming thecage. 7 Y

hollow base, a cylindrical. member carried by said b se, an electric lamp socket secured Within said cylindrical member, a knockdown cage having inturned ends projecting into said cylindrical member adjacent its up per edge whereby said cage is pivotally and permanently secured to said cylindrical member at its ends, said cage adapted to be knocked down without removing it from the cylindrical member and reassembled without the aid oftools for forming a protecting cage for said bulb, and means for detachably securing said members together when in assembled position.

3. A device of the class described. comprisfig a base, a cylindrical lTiQIDlJQl having a reduced concentrically located upper portion carried by said base, there being'a plurality of'diametrically opposite openings formed through the wall of the reduced portion, a plurality of substantially U-shaped members having a portion at each end inturned, said inturned portions adapted to pass through certain oi said openings in the reduced portion whereby said membersare .pivotally mounted, the ends 01 said inturned, portions beingbent so as to secure the members against removal, and an'electriclamp socket concentrically mounted in. thereduced por: tion ofthe cylindrical memberl. 7 I In testimony whereof I haveafiixed' my signature, f
