To all whom it may concern:

`Beit; known that I, FRANK E. KrNsMAN, a citizen of` the United States, and-a. resident of Plainfield, inthe county of Union .and State of New Jersey, have invented a certain j new. and useful Improved Street-Car Light f""ve1tin relates fstefjrilwy cm; improvemeit'lonthose systems in whichlthe sliting are operated-.ine bm r-upplyfwieexteriotf l in-:jthe-'fpresentsystemsof electc p'oriulsn Qfiers 'rho` objocttqf'zmy m negate '.isovide lfor accidental disconnection of he'branch from the supplgkwre, whichtrequentlyarises' from the trolley leaving theffspplvtii.

'i As'my'invention is primarily `intended for applicatioiifto electric-railway cai-s, I have illustrated the invention diagrammatically in 35."the accompanying'drawi'ngsas so applied, wherein-g a Figure l presents the preferred larrangement, and Fig. 2 a modification of a portion thereof.

4o L indicates a Asec'ti'on'of line-or 'Workingconductor. which serves to supply current to a branch 3 on the car, the circuit of said branch being completed, as usual, through therails R or any other return-conductor in the usual or proper manner. y B isA anycollecting device which moves over thejconductor L and takes up the cur'- rent for use on the car. ,i

Thedrawings indicate-the ordinary trolley,

5o the conductor L being in the case illustrated an overhead wire; but,'as will be well.

and is designed 'as'an cars-'propelled from overhead wires nonto any particularconstruction of collector; 5 H indicates-any number of electric lamps for lighting the car operated by the Acurrent in the branch 3,- -represented in heavy lines, to theretum R otherwise.

hundred-volt `circuit. I indicates the substitute lamps, which are 'fto be used for lighting the carin the event Lamps I in circuit 4, represented in broken lines, may bev of any desired candle-power; but they are run in'multiple to adapt them for operation *.by'a lsmall number of couples ot In the "preferred n iarrner4 'of carryingout branch @indicated-bja fine line, which contains a resistance Re,an`d vwhich passes to the return R'fthro'ugh the armatureJ of a magnet K, locatedinth circuit 3 in series with the lamps H. In the circuit 5 is also .located a magnet M, whose armature controls the multiple circuit 4 of lamps I. In this arrangement the storage-battew' anda resistance are in multiple with the lamp-'circuit 3., From the circuit 5 in -advance of the resistance Re a branch through the motor O leads tothe return R. The resistance Reis of a sufficient number of ohms to prev nt the charging of the storage-battery until Ehe current passing through the motor has reached a certain voltag reriistance Rc to enable themagnet M- to hold up its armature, which it does until a rupture occurs in either branch 3 or 5. AA rupture of leaving the conductor or the breaking of a lamp H or cessationaefcrrent over the conductor L de-energizes the magnet K, allowing itsarmature :to fall back-and break the by way of the Wheel NV) or A 6o In the `present instance I have shown .my Mention, asgcarried out in connection with incandescent lamps H, which' together'arcof f proper voltage for operation from a'veof the failure of'lamps H from any cause.
