' Application filed February 18, 1889. Serial No. 300,235. (No model.)

To all whom it may concern:

Be it known that I, LUDWIG GUTMANN, a subjectof the Emperor of Germany, and a resident of Fort WVayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Electric- Railway Systems, (Case 25,) of which the following is a specification.

This railway system has for its purpose to distribute safely and economically electric energy over large distances, and is such a system in which hightension currents are used in combination with converters. The organization embraces one or more generators producing alternating, pulsating, or intermittent currents of constant potential, each having their independent feeder-circuits provided with switches or other means for connecting two or more feeders to one genera-- tor, converters permanently connected with their primary coils to said feeder-circuits in multiple arc, and the secondary coils of the saidconverters left normally open and only closed by moving translating devices, such as electric motors on cars, said motor automatically connecting the secondary coil of the nearest converter to the work-line and disconnecting the converter which last sup-V plied it with current. 'By this system I do not use more converters than necessary and each only for aib'r'ief ftime, thereby increasing the life of such apparatus, reducing the strain on the insulation,and (as not all converters are doing work'but only a portion) it will be evident that the power supplied will be very nearly proportional to that consumed; further, the amount of leakage is minimized, and, lastly, I may use a much smaller conductor for the work-circuitv than otherwise would be required, because the motor is always supplied by the nearest converter and because there is practically but very little loss in conveying the electric energya short distance This construction is equally applicable to a system having either both the conductors overhead or one overhead and the other underground, or both undenqround.

This figure shows the angular piece 0 in a position at right angles from that of Fig. .3. The secondarywire pene-.

inthe groove k.

trates the plate .0, and is connected to s, which j are contact blocks or terminals mounted on the insulation fl and distributed between every alternate pair of blocks h, which arethe terminals of the main conductor 1', which rests.

In Figs. 3 and 5 the projections g are more clearly shown. The angular side piece d is similar to c and is fixed on or is resting on the plate 2 in the same manner as c. The side plate dis not required for opening or closing of any circuit, and it is therefore not provided with a conductor or contact-blocks.

To prevent too great expansion of the ends of spring f,-the side (Z is provided with an insulating-block Z.

In the normal condition of the system the 7 primary coils are closed, as shown in Figs. 1

and 2, but the secondary coils are open; the latter being closed by circuit-closers operated by the moving train. These circuit-closers aref.

' sition indicated in Fig. 3 forcing the ends of f apart, which rest on one side on contact-blocks. h s, completing the circuit from conductor 8 to conductor a. On the other side, against block Z, no circuit is closed. The secondary circuit being closed, causes the current to flow from conductor S, contact-blocks s and h, circuit-closers f, rail (0, to motor exciting-coils, and from motor in the reverse order to the other pole of the converter-coil. The rail a is insulated fromc and d by insulation 1), attached to either side of a. As soon as the pressure ceases a will be forced up by springs w, and the secondary circuit will be open again. The slot between 0 and d is filled and protected by rail a,-which in Fig. 3 has a T- shaped cross-section and prevents the falling of dirt into the conduit. By this construction (everything being movable) any obstacle can easily be removed and the whole system can quickly be inspected simply by lifting out the rails a and, if necessary, the angular piece cl.

Figs. 8, 9, 10, and 11 represent a modification of Fig. 3.

In Fig. 8 everything is the same as in Fig. 3, with exception of the modified form of rail 0. and circuit closer f. The cross sectional shape of a is that of an arrow. It is forced upward by spring w and'closes the aperture between 0 and d, slightly projecting over the surface. 7

Fig. 10 is a view of rail to at right angles to that of Fig. 8. a is provided with the same projections and tension-springs as in Fig. 4. The rail having to operate the levels f of thecircuit-closers f is provided with holes for the location and passage of lever f, Figs. 8, 9, 10, and 11.

In Fig. 8 blocks h are placed ina more p rotected position, and circuit-closer f is supported by standards If.

. In Figs. 8, 9, and 11 the projectionu on standardt serves as a guide for the rail or; so

does block 1:, Figs. 8, 9, and 10, which inaddiplates 0 and d, Fig. '9, so that when both conductors are placed side by side and both rails should bepressed down simultaneously by a I car or a horse placing the rails level with the surface the circuit is not completed, and consequently no shocks experienced. 1

Fig. 9 shows the circuit completed when the contact-wheel a: or brush .2 or any other suitable apparatus designed for the purpose depresses the rail ct below the surface. The electrical connections of Fig. 8 are the same as in Fig. 5. It willbe noticed that'in the normal condition of the system the secondary circuit is open and the conduit is closed by rail a, while when occupiedby a car or train 5 the wheel a: depresses the rail a for a-short time and closes the secondary circuit,- which 7 is opened again as soon as the car has passed the said rail. The rail to has been provided at the highest part witha dulLknife-edgeto 10c prevent anything from resting on it, and to oppose any formation of ice or' the likeon the contact-surface.

Fig. 11 shows a view from the toponthe. circuit-closer f, lever f, and the support 25, on IO 5 which they are movably mounted, also the relative position of the movable rail or. to the lever f. Y

Fig. 11 shows a perspective view of circuit-closer f and lever f on an enlarged scale. no
