This invention relates to new and usefulim provements in brackets. ` » One object of the invention is to provide an improved bracket which-is particularly adapted 5 for use in supporting the usual “Lumiline” lamp. An important object of the invention is‘to pro vide an improved bracket which is arranged to be attached to the ordinary “Lumiline” lamp without changing the structure of said lamp, l O whereby the _lamp may be connected with the ordinary electrical outlet terminal, the bracket serving not only as a support but also' as an electrical/connector, which eliminates the neces 1 sity of employing a separate specially constructed' bracket for illuminating the lamp. ` Another object of the invention is to provide an improved bracket for a “Lumiline” lamp which is so constructed that a plurality of "Lumiline” lamps can be placed in longitudinal alignment 20 and electrically connected to a plurality of the usual electric sign receptacles or outlet terminals, the bracket being adjustable vso that the con nection may be readily made, irrespective of' the position or location of the receptacles. 2 Ul A further object of the invention is to provide an improved bracket for a “Lumiline” lamp, which bracket is secured to the usual removable y ¿ Figuren` is „a,'view` similar to Figure 4, and showing a modified form of bracket, and Figure 7 is a transverse, sectional view taken through one of the caps arid showing ‘another4 f way of securing the'bars to the caps. ' ‘ ` In the drawing,the numeral I0 designates an ordinary “Lumiline” lamp such as is> manufac tured and sold by the -Generall Electric Company. 'I'his'lamp is cylindrical, being tube-like, and is made in standard Ylengths of 12 and 18__vinches. 10 Each end of the lamp has a metallic terminal Il which is _formed with a central recess l2. ‘ A ilanged insulating cap `I3 isadapted to lit over each terminal and this cap is` provided with an annular spring contact i4. . When the capis 15 placed over the terminal, the contact I4 fric tionally engages Vthe wall of the recess |2S'With a " ' releasable snap-fastener eiîect/to hold the cap on the end of the lamp, and also to make elec trical contact with the terminal. A metallic‘ear 20 orlug VI5 of electrical conductivity'extends out wardly from one side of each capand this lug is preferably made integral Withthe contact I l. All of thev above described parts are of standard manufacture'and form no part ofthe present 25 invention.v ’I'hey have been described merelyfor the sake of clarity. , y Y It is the usual practice to provide with each inserted between or removed from the caps with “Lumiline” lamp, a specially cónstructed> base (not shown). This base has spring clips which v30 have electrical lead wires >connected therewith, - A construction designed to carry out the. ln vention will be hereinafter described, together with other features of the invention. The invention will be more readily understood 35 from a reading of the following specification and -by reference to the accompanying drawing, in which an example of the'invention is shown, and wherein: , , Figure‘l is an isometric viewof an ordinary “Lumiline” lamp having a bracket, constructed - in accordance with the invention, attached thereto, ., l Figure 2 is a view partly in elevation and part 4 Ul . caps of said lamp, whereby the lamp may be 30 out disturbing the bracket. ' 4O (ci. 17a-32s) ly in section, and showingçthe bracket engaged in the usual electrical outlet terminal, Figure 3 Vis an enlarged isometric view offone end ofthe lamp and bracket, A , Figure 4'is a diagrammatical view showing a 5o plurality _of the “Lumiline” lamps in longitudinal alignmentand theconnection by the brackets with the usual outlet terminals, , Figure 5 is an elevation showing how the “Lumiline” lamps may be employed in forming Y 55 a letter in an electric sign, and the spring clips are arranged to receive the metallic lugs or ears I5. The base may be se cured to a Wall, or other' suitable place. , It is not only expensive to manufacture a base vi'or 35 each lamp but it is impossible to electrically con nect the lamp proper with the usual outlet ter minal such as _an attachment plug outlet, or signreceptacle. Therefore, the lamp l'cannot be used unlessfthe specially constructed base'is pro- 40 vided. ' ` ' f ’ A Y , -In carrying out the invention, a Ybracket I6 which not only serves asa support for the lamp, but also may be inserted in the usual electrical attachment plug outlet, whereby the lamp may 45;--> be connected with s'aid outlet, isk provided. 'I'he ' bracket includes a pair of ñat electrical conductor bars l1. Each bar as shown has one end soldered, e or otherwise suitably secured, to the inner side of oneV of jthe metallic lugs >I5 provided on the 50' respective caps i4. ’I'he bar extends parallel to the lamp and has its opposite end‘bent outwardly from the lamp` so as to form a prong I 8. As is clearly shown in Figures 1 and 2, the bent meeting ends of the pair of bars extend parallel to each 55 2,134,270 2, other, whereby the prongs formed thereby are spaced from each other. The thickness of the bars I8, as well as the spacing between the prongs is such that said prongs may be inserted in the usual pair of slots I9 of the female portion of an electrical outlet attachment plug 20. Since one end of each bar is connected with the lug I5 of one of the caps ofthe lamp and the opposite end is inserted in the electrical outlet 10 attachment plug 20, it is obvious that the elec trical current is conducted to the terminals I I of the lamp, whereby said lamp is illuminated when the plug is placed in an electrical outlet socket. The electrical conductor bars I1, which 15 form the bracket, are covered with a suitable insulating material 2i such as rubber. ' From the above, it will be seen that a cheap systems including outlets or receptacles, irrespec tive of the position of said outlets or receptacles; It is noted that the bracket not only serves as a support for the lamp but forms the electrical conductor for connecting the lamp with the out lets. In Figure 7, another method of securing the bracket to the cap of each ¿lamp is shown._ In this form, each bar I1 is hingedly secured by a pin or rivet 25 to the ear I5 of the cap, but with 10 a suiiicient tightness to support the weight of the lamp, yet it is forcibly movable for adjust ment. With such arrangement the lamp can be swung a »limited distance with 4relation to the bracket, `so=that when several lamps are in align 15 Vment and any one lamp burns out, the burned out lamp may be swung out of alignment with and inexpensive bracket, by which the “Lumiline” the othersrto permit removal and replacement of said lamp. „ ’ lamp may be directly connected with the ordi What I claim and desire to secure by Letters 20 20 nary outlet attachmen't plug is h`ad.

In such case, one of the arms I1 of the bracket of each lamp is short ened so as to reach the nearest receptacle. Thus, 3. A supporting bracket for an elongate tubu lar lamp of the type having a metallic terminal having a central recess a't each end, consisting of a pair of separate electricalcurrent conduct» - ing bars extending in opposite directions from the prong of this arm is engaged in one of the each other, each bar at its outer end having a slots of said receptacle to connect the lamp with 60 one side of the electrical circuit. The other arm relatively short forwardly directed electrical ter minal facing the terminal on the other bar and Il of the bracket is of such length as to engage the receptacle nearest this end of the lamp,and its prong engages one slot of the nearest recep tacle, whereby the circuit to the lamp is com It would be possible, however, to con struct one arm longer than the other (Figure 6) so’ that the prongs of both brackets engage the 65 pleted. same receptacle. In such case, it is only neces sary to lengthen one of the bars and shorten the other, and then bend said bars to form the prongs I8. With such arrangement, said prongs may be formed at any point along the length of the lamp, whereby the lamps may be placed end to end, and electrically connected lto the present wiring 60 having contact means consisting of a substantially l flat contact with projecting spring iingers fric tionally engaging the metallic terminals of the lamp, a cap of insulating material enclosing each of¿ the electrical contact means on the bracket bars and the ends of the tubular lamp, whereby the lampl is supported by the bars and'in close proximity thereto, and rearwardly directed flat contactprongs on the adjacent inner ends of the bars to plug in an electric outlet and there 70 by maintain the bars in their lamp supporting bracket formation. .
