ELECTRIC RAILROADING.

Specification of Letters Patent.

Patented Aug. 27, 19 07.

Application filed April 15, 1907. Serial 1%. 368,328.

My invention relates to an improvement in electric railroading.

Its object is to produce an efficient arrangement, whereby electric railroading with the aid of high tension currents may be accomplished without undue effect on neighboring wires.

In railroading of to-day, most generally the rails are used as -the return. I am aware that in earlier days when direct currents of comparatively low voltage were used, both the circuit wires were placed overhead, and the two trolley wheels, separated on a vertical arm connected each with one of the circuit wires; but in railroading of to-day where an alternating or phase current of ten thousand or more volts is used, it would be imprudent to bring the two wires of the power circuit as close together as is required in the arrangement as practiced before with the direct current of comparatively low voltage. To obviate this difiiculty, to produce an arrangement whereby the rail return can be dispensed with and yet the over-head wires reduced to a minimum, is the aim of my invention.

In the drawing, Figure 1 is a plan view of the track and wire system and a diagram of the connections with the gentrator. Fig. 2 is a rear elevation of the car. Fig. 3 is a plan view of part of top of the car, showing the c'onnnections of the trolley wheels with the power.

wire.

1 is the generator; 2 and 3 are brushes or terminals of same; the terminal 3 being connected with the lines 4, 5 and 6 and the terminal 2 being connected with the lines 7, and 8. i I

9, 10, 11 and 12 are tracks on the road of travel.

I have illustrated here four tracks, for the reason that on parts of the road with large travel, generally one incoming and outgoing track is reserved for pascurrent wires and all lines connected to the brush 2 the return wires. The track 9 has the outgoing circuit wire 4 and return 7; the track 10 has the outgoing circuit wire 6 and the return 7 which is common with the track 9; theitrack 11 has the outgoing circuit wires 6,

which wire is common to. both of the tracks 10 and 11 and has the return 8; the track 12-has the outgoing circuit wire 5 and has the return '8, which is common to both the tracks 12 and 11. It is seen that with this arrangement, the least number of over-head or trolley lines is required for .a system where ground or rail returns are eliminated.

It is now necessary to describe the arrangement of trolleying these wires, so that the same may be placed as for apart as possible and not close enough, so that any danger may arise from the swaying of the wires,

or the leakage of the currentfrom one wire to the other.

The arrangement I prefer is illustrated in Figs. 2 and- 3. In these figures, 13 is the car proper of which 14 is the roof and" 15 and 16 are the two trolley arms, the

arm 15 provided with the wheel 17 and the arm 16 provided with the wheel 18. The trolley arms are held by the springs 19 and 20. Thesprings and arms are mounted on the base 21. With this arrangement, the two wires of one circuit incoming and outgoing, are kept so far apart that no danger can arise through leakage or breakage, for it is well known that between one track and the second track, there is a space of so many feet thata coming together of the wires or leak ing of one wire from the other is out of the question.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. A system 0! electric railroading comprising more tracks and live over-head wires forsaid tracks, the outside of the outside tracks provided each with one wire connected to a common terminal of a generator, the inside of said outside tracks provided each with one wire connected to the opposite terminal of said generator and the inside of the two inside tracks provided with a common wire connected to the first named terminal of said generator.

In testimony whereof I aflix my signature in presen'ce'of two witnesses.
