ELECTRIC LIGHTING OF RAILWAY-TRAINS.

SPECIFICATION forming part of Letters Patent No. 432,657, dated July 22, 1890.

Application filed December 26, 1889. Serial No. 334,947. -tNo model.)

To all whom it may concern:

Be it known that I, ILLIUs AUGUSTUS T1M- MIS, a subject of the Queen of Great Britain, residing at 2 Great George Street, XVestminster, London, S. WV., in the county of Middlesex, England, have invented certain new and usei'ul Improvements in the Electric Lighting of Railway-Trains; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification.

The objects of my invention are to lessen the weight of the apparatus, especially of the batteries, to economize the electric current and lessen the expense and increase the light. With these objects in View and referring to the drawings herewith as explanatory of the following description Figures 1 and 2 are diagrams illustrating electrical apparatus embodying my improvement and adapted for two cars of a railwaytrain. The apparatus illustrated by these two figures are so similar that I can readily describe them together with mention of their special features, as may be necessary.

D designates a dynamo-electric machine, which may be arranged upon any suitable part of the train-as, for instance, in the guards van of such a train as is common in Europeon the locomotive or in its tender, (ir

t is intended to be driven by means of a special engine, which is supplied with steam either from a special boiler or from the locomotive. Main positive leads B and negative leads A are fitted to extend under each car. Those of the forward car are connected with the positive and negative leads of the dynaino, and these negative and positive leads A B of the several cars are intended to be coupled together.

E designates a positive lead for charging batteries which are used, as will hereinafter be explained.

From the through leads A and B, I tit main lighting-circuits L and L' in each vehicle with the necessary lamps m m. The lamps are shown inseries of pairs and all the pairs in parallel. They lnay be placed in any convenient way. These leads A B E and other through leads I joinor carry throughk from vehicle to vehicle by means of special couplers of any available kind. Thus I light the main lamps directly from the dynamo, which enables me to use a high-voltage current and get more light and insure economy, and I require no batteries for the main lighting; but as vehicles may be taken or break loose from the dynamo-circuit, and in day-time it may be advisable not to work the dynamo-say, for instance, in going through a tunnel, and yet lights are needed-I place a small lamp n n of low voltage in each vehicle. It will be seen that these lamps are arranged between special or auxiliary circuit-wires Hand the circuit-wires L', and that the circuit thus formed is in communication with secondary battery b I), placed in any suitable position in each vehicle. The return-lead from both the lighting-circuits is shown at L L', but sepa .rate leads may be used. Local switches s s are shown in both thelighting-leads. When the local switches in the auxiliary circuits are closed, the lamps are lighted in Fig. 2. I t another or relay switch S, Fig. 2, in these auxiliary circuits, which works as follows: In

each of the main lighting-circuits I place a relay R in each vehicle, which actuates the relay-switch S and breaks the auxiliary circuits when the dynamo is running, so that when the main lamps are lighted the auxiliary lamps are not lighted, but if any Vehicles are separated from the dynamo circuit the auxiliary lamps automatically light up.

The auxiliary lamps of each car will be extinguished whenever the main leads of that car shall be again coupled in the train.

Instead of putting the relay R in thermain lighting-circuitI may put it in a separate or controlling-circuit c, as at R', Fig. 2. This controlling-circuit is joined to the through coi'itrolling-lead D and the general negative lead A, and when it is required to be worked the two leads D and E are joined by the switch S', (see Fig.l 2;) or, instead of using a controlling-lead D, as in' Fig. 2, I use an auxiliary lead D, (see Fig. 1,) to which I join the auxiliary lighting-leads Z,.and by joining the lead D to the lead E by switch S', Fig. l, the auxiliary lamps are lighted.

Vhere a communication system is used between the guard or other attendant and passengers, I put in a communication circuit-wire ICO or conductor c, together with bell I, and pull or push knob K in any position or positions required, and when the knob K is actuated it establishes a circuit and the bell I is rung. A special battery Y may bc used or the battery b.

The couplers are made so that when any vehicle is taken or becomes detached from the train the circuits D and E or any circuits that may be required to be joined automatically make junction. Such couplers may be located at the points a;

There is a special resistance r in the dyname-circuit to the batteries, and there are resistances t, where required, in the auxiliary lighting-circuits, and also, but not shown, in the main lighting-circuits, if required. There are switches 7i 71 in each of the dynamo-circuits.

Although I have used the term and described a dynamo for generating the electrical current, it is to be understood that I do not limit myself thereto, as I may employ other main source of electricity without departing from the spirit of my invention.

Having now described the way in which my invention may or can be carried into effeet, I desire it to be understood that what I claim isl.
