To all whom it may concern:

Be it known that I, REUBEN B. Bnnqamn, a citizen of the United States, residmg at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Hand Portable Electrical Receptacles, of which the following is a full, clear, concise, and exact description, referdrawing, forming a part of this spec catlon.

This invention relates to a hand portable electrical receptacle and more specifically to a device designs for use in connection with .a hand movable electric light to house and guard the same during usage. Electrical devices of this character, becauserof the portability thereof, are necessarily subjected to bumps, shocks and jars, which frequently result in breakage of the lamp globe A further object is the production of a 'fixture of the character mentioned in which the terminal or current conducting parts will be positively sealed against contact with outside gases or the outside atmosphere.

A still further object is the provision of a device of the class referred to in which the receptacle or hou will be formed of a plurality of detacha ly connected sections which will be locked together in such a manner as to effectively guard against theft of the lamp.

A still further object is the provision of a fixture as mentioned whichvwill be of durable and economical construction, of pleasing design, and highly efficient in use.

Other objects will appear hereinafter.

In the accompanying drawings forming a part of this specification, and in which one embodiment of the invention is shown Fig. 1 is a sectional view of a hand portable electrical fixture embodying the invention, the same being shown arranged in operative relation with an electrical lamp and its base;

Fig. 2 is a section taken on substantially line 2-2 of Fig. 1;

Fig. 3 is asection taken on substantially hne 3-3 of Fig. 2;

Fig. 4 is a'section taken on substantially line 44 of Fig 3;

Fig 5 is a. perspective view of the lower portion of the upper section of the-body of the device; 7

Fi 6 is a perspective view of the upper portion of the lower section thereof;

Fig 7 is a section taken on substantially line 7-7 of Fig 1, the electric lamp being omitted; and

Fig 8 is a fragmentary section through the locking element employed to lock together the two sections of the body of the device.

The preferred form of construction, as illustrated in the drawings, is designed for use in connection with an electric lamp 10 of conventional design, said lamp being mounted in a porcelain insulating base 11 in which is provided the usual side or shell contact 12 and the center contact 13, which contacts are held in place, for cooperation with the lam by means of the wiring terminals 14. aid wiring terminals serve as connections for the electric conductors 15, which are enclosed in a conventional insulation 16. To insure against contact between the ends of conductors 15 connected with terminals 14, a baflie 17 is provided which is formed centrally upon the rearward or upper side of base'll, as clearly seen in Figs. 1 and 2, and which effectively separates said conductor ends.

Enclosing said lamp and its base is a receptacle or housing of sectional formation, the same comprising an upper sheet metal cup or bell shaped section 18 in the upper or inner end of which is seated a cushion 19 of rubber or other resilient material against which the adjacent end of the base 11 is adapted to seat. Said cushion is of substantial hemispherical form and is pro vided with a central opening to allow for the passage of the conductors, said opening being, however, of such size that said cushion snugly embraces the conductor insulation 16 so as to form a positive seal around the same and prevent the passage of any gases through the joint. 7

To assist in preventing accidental disconnection of the conductors from the terminals, a clip 20 is applied to the conductor insulation 16, and the upper end of Applied to the date and embrace said clip. t al so a conven ion conductor insulation is a guard or armor 22, one end of which 1s securely fastened in the rearward end of the lamp base in section 18, during application or removal of the lamp, said section is provided with diametric internal beads 23, which engage with correspondingl positioned recesses or notches 24 provided i base, as clearly seen in Figs. 2 and 3. Said recesses extend from the 1nner end of said base so as to permit of engagement of said beads therewith when the base is slipped to position in the section 18, as will be readily understood. a

Cooperating with section 18 is a lower receptacle section 25 of reticulate formation, the same being made up of a plurality of spaced crossed wires resulting in the production of a guard of substantially the same shape as the lamp globe in connection with which it is to be employed. Said guard 25 is rovided at its upper or rearward end wit a circular band 26 which is adapted to snugly fit within a circular flange 27 formed at the mouth or lower end of section 18. Said band 26 is formed through a stamping and punching process with a plurality of spaced an ular exterior recesses 28 and circumferentlally extending, downwardly .fac ing shoulders 29. The flange 27 of section 18 is correspondingly formed with a p1urality of spaced inwardly projecting portions 30, producing circumferentially extending upwardly facing shoulders 31. The arrangement is such that a bayonet joint is formed between the

sections

18 and 25, the portions 30, in the connectionof said sections, being adapted to enter the recesses 28 and the shoulders 29, upon clockwise rotation'of said section 25, being adapted to engage with shoulders 31 to lock the parts together, as will be readily understood. In disconnecting said sections, the reverse movement of the parts is, of course, resorted to.

In order topositively lock said sections together so asto prevent surreptitious removal of the lamp, the band 26 of section 25 is formed with diametrio openings 32, either one of which will be adapted to register with an opening 33 in section 18, when said sections are in interlocked relation. When .said open g 33 is in registration with one of the ope mgs 32, a metallic eyelet 34 is inserted therethrough and upset by a suitable instrument, as seen in Fig. 8, thereby locking the sections against relative rotation and thus reventing disconnection thereof. With th s arrangement, in order to disconnect the sections so as to gain access to the lamp, it will be necessary to first destroy and remove the eyelet 34;. This hen said ing the case, saideyelet will have a decided deterrent effect upon contemplated theft and will be far moreefl'ective as a itive lock than a bolt, nut, screw or other evioe which could be removed without destruction or mutilation of any part in order to efiect the desired unlocking. i

Engaging against the outer end of the lamp 10 is a wire loop 35 of a diameter less than the-maximum diameter of the lamp, and coo eratin with said loop is a plurality o radial y extending 'angularly disposed helical tension springs 36, the inner ends of which are connected with said loop, and the outer ends of which are connected with the receptacle section 25, as clearly seen in Fig. 1. The arrangement is such that said springs will exert a pressure upon the lamp which will force the base thereof against the cushion 19, said s rings and cushion thus exerting upon sai lamp and base opposing pressures which serve to yieldingly hold the said lamp and its base in central or operative position. With this yieldable mounting of the lamp, the same will be effectively guarded against breakage through .jolts and jars to which the fixture is sub ected -in use, sincethese jolts and jars instead of being communicated to the lamp will be absorbed by said cushion and springs. The life of the lamp will thus be materially extended.

At the-mouth or outer end of the base 11 is provided an annular resilient member 37, of rubber or other suitable material, which is positioned for engagement with the usual annular shoulder 38 provided at the rearward end of the lamp globe, said base being recessed or beveled as at 39 to accommodate said member. The arrangement is such that said member 37 serves to additionally yieldingly support the lamp, and'to frictionally ho d the same against accidental unscrewing or detachment from its base. At the same time, said member 37 also serves as a seal, the same cooperating with the cushion 19 in forming a positive seal for the parts within the lamp base against contact with the outside atmosphere or other ases in which the fixture might be used. T is is of special advantage in that it guards against ignition of explosive gases where the fix'- ture .is used in such places as garages, 'where explosive gases are often beln generated and discharged. This sealing eatu're is of further advantage in that it also revents fumes and acids, such as would be ound-in chemical works or like places, from attacking and destroying the metallic parts within the lamp base.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
