SPECIFICATION forming part of Letters Patent No. 562,766, dated June 23, 1896.

To all whom it may concern.-

Be it known that I, RUDOLPH M. HUNTER, of the city and county of Philadelphia and State of Pennsylvania,. have invented an Improvement in Electric Railways, of which the following is a specification.

My invention has reference to electric railways; and it consists in certain improvements, all of which are fully set forth in the following specification and shown in the accompanying drawings, which form part thereof.

This application (Case No. 284) is a division of my application, Serial No. 214,309, filed September 23, 1886.

My improvements comprehend certain features comprising a main track and a branch track with an electrically-actuated switch adapted to be controlled by or from a traveling vehicle, and will be better understood-by reference to the accompanying drawings, in which- Figure 1 is a diagrammatic plan view of an electric railway embodying my improvements. Figs. 2 3, 4, and 5 are cross-sections showing modified arrangements of the electric circuits which may be used upon the railway. Fig. 6 is a side elevation of an elec tric car adapted to use with invention. Fig. 7 is an end View of a modified form of currentcollector, and Fig. 8 is a perspective view showing my electrically-actuated switch applied to railways having suspended conductors.

Referring to Fig. 1, I have the branch railway 1 arranged parallel to the main track, and with the electric conductors B B arranged in the order shown, in which the conductors of different polarity on the main line and branch tracks are arranged alternately and electrically connected to the corresponding poles. of

the generator A. The branch line of conductors I has connection with the main line by a moving switch-point I.

A car may be run upon the main track and down upon the branch track, or vice versa, the

switch admitting of this without turning the car end for end. This branch track may be used to store surplus cars, or may be operated as one of the main branches to the main track in carrying passengers.

means of rollers t" on the cars.

The switch may be operated automatically as follows: An electric motor 1' (two forms being shown) is connected to move the switchpoint- I and is operated in a derived circuit 1 connected with positive and negative line conductors. This derived circuit is provided with a switch I", which is operated to make or break the circuit I and this is secured by By making the switch I to close under a spring-action due to spring 1', the cars of the main track may pass freely up the main track contrary :to the point of the switch; and in returning,

where they are not required to go upon the branch track, the rollers i of the car C operate the switch I so as to cause the motor to open the track-switch I and permit the cars to return on the main line. In those cases where the cars are to run upon the branch track the car need not be provided with rollers i, and in this case the cars will be di rected onto the branch track by the switchpoint. In other words, normally, the circuit I is broken, and the switch I closed, so that cars which do not operate the circuit-closer switch I might pass on down the branch track,

.but those which must pass down the main line are arranged to automatically close the circuit I and thus control the motor 1 cans ing it to open the switch I to permit the cars to pass on; and as the car passes the switch I, to open the circuit-closer switch I and thereby break the circuit 1 allowing the switch I to once more close.

It is evident that if desired the main line may be left open normally and certain of the cars arranged to close the switch and pass to the branch track.

l desired, the track-rails may be the returnconductors, and a suspended conductor used as the positive conductor, as shown in Fig. 3. It is also evident that one or both of the conductors may be placed in a conduit, as indicated in Fig. 4.

Fig. 6 shows an electric car adapted, for example, to the particular system shown in Fig. 3. D is the electric motor. E is the motorcircuit; 6 the current-controlling device or regulator, and O the collector. In case of the conduit the collector is made in the form shown in Fig. 7, which makes a traveling contact with the conductors by means of roller-contacts 0 arranged on the bottom of the shank O, which is carried by the car and extends through the slot of the conduit.

The switch I is adapted to any of the conductors or rails as may be found necessary. In the cases where the rails are used as conductors the wheels act as collectors or contacts, and these are guided by the electricallyactuated switch.

My invention applied to the system of railway of Fig. 3 is shown in Fig. 8, in which the rails B act as the negative conductor or return, and the suspended conductors B act as the positive conductors.

I is the track-switch and is operated by the electromagnetic device I The switch I", moved by the car, controls the circuits I H, which supply current from the suspended conductors B to the electromagnetic device 1 I do not confine myself to the mere details of construction, as they may be modified in various ways without departing from my invention.

Nhat I claim as new, and desire to secure by Letters Patent, is

1. The combination of a main railway, a branch or turnout railway, a switch-point for the track at the junction of the two railways, an electric-power device for moving the switch-point, a source of electric energy, circuits for supplying energy to the electricpower device, a switch for opening and closing the electric circuit adapted to remain open or closed of itself and maintaining the electric circuit in open or closed condition for periods of time after the car has ceased to act upon it, a traveling car, and means upon the car for both closing and opening the electric-circuit switch in a positive manner.

2. The combination of a main railway, a branch or turnout railway, a switch-point for the track at the junction of the two railways, an electric-power device for moving the switch-point, a source of electric energy, circuits for supplying energy to the electricpower device, a switch for opening and closing the electric circuit and maintaining it in open or closed condition for periods of time, a traveling car, and means upon the forward and rear portions of the car for closing the circuitswitch and after it has remained closed and the car passed upon the branch track to open the circuit-switch.
