Specification of Letters Patent.

Patented Dec. a, rare.

Application filed March 21, 1916. Serial N 0. 85,684.

To all whom it may concern Be it known that I, ADOLPH KERN, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented new and useful Improvements in Indicating Systems, of which the following is a specification.

This invention relates to an indicating system for cars passing each other upon parallel tracks, by means of which signals will be given as to Whether that portion ofthe track on the opposite side of a particular car is occupied. v

The primary object ofthe invention is to provide means the elements of which are so arrangel that a signal will be given continuously until the lengths of both cars are plainly visible, with the advantage that it will be impossible for a person to pass around the rear 'ofone car into a position in advance of the car on the opposite track.

An object of the invention is to so arrange the' sources of current relative to the circuits and signal devices that the sources of current will be arranged in series thus decreasing the size of each generating unit.

Another object of'the invention is to so construct the brushes that good electrical contact will be had at all times irrespective of the oscillatory or vibratory movement of time required by a car to travel twice itslength.

lhe invention will be better understood from the following detailed description taken in the accompanying drawing wherein a preferred embodiment is illustrated and the features of novelty including all the above mentioned and various others will be hereinafter pointed out in the appended claims.

In the drawing: Figure 1 is a diagrammatic view illustrating the application of my invention. Fig. 2 is a longitudinal sectional View through one of the brushes. Fig. 3 is a sectional view on line 3-3 of Fig. 2. Fig. 1 is a diagrammatic view of the wiring.

Referring to the drawings it will be seen that my invention is designed to give signals by the passing of cars upon parallel tracks 1 and 2 as illustrated in the drawing. I wish it to be understood that the apparatus can be designed to give signals from a plurality of parallel tracks this being readily accomplished by having both sides of the car provided with my apparatus.

Each of the Passing s 3 and e have Each as to compensate for the oscillatory or vibratory movement of the can The wiper'll is continuously held in engagement with a contact rail by means of a coil spring 12encircling a binding post 13 which is slidably mounted in the frame 8 and rigidly connected in the wiper 11. Each car carries a source of current 14 such as an electric generator and signaling devices 15 shown in this particularinstance as electric lamps arranged one at each end of the. car so, as to pro ect the light rays in a direction to be visible by a person endeavoring to cross the track. I a J 1..

The signaling devices 15 of each car are arranged in series with each other by means of the conductor 16 that has its terminals connected respectively to the ends of the contact rail 5. Each car has its pair of shoes electrically connected together by means of a conductor 17 at this point I wish to call attention to the fact that the generator is bridged across the conductors 16 and 17. From this arrangement it will be seen that when a shoe 7 of one car engages the contact rail of another car and the other car performs the same function the generators will'be thrown in series with each other and all of the signal devices rendered active by the passage of current as illustrated by the arrows. Another advantage of my arrange ment is that owing to the arrangement of the circuits, shoes, and signaling devices, the resistance of the latter to the flow of current will be materially reduced because other. Upon the advance shoe leaving the contact rail the rear shoe takesup .the duty of providing a path for the current and thus 7 a person cannot passaround the rear of oneit will be seen that by my. arrangement the signals will be continuously given for aperiod equal to the time required by a car to travel twice its length and as the result car into a position in'advance of the car upon'the opposite track without being given a signal. ,I therefore do not desire to be limitedin these parti'culars'or in any others except; as set forth inthe appended claims.

'I for each car, a signaling device for each car 1 rendering said signaling devices active, said length of the car.

'so. v cl-udlng a source of current and a signal,

normally out' of circuit with said generator and means carried byboth'cars cooperating for 'connectlng thegenerators in series for means including a contact rail extending the .2. An electric indicating system 'for cars traveling on parallel tracks, arcontactrail foreach car secured' to'the side thereof, a

shoe for each car and arranged to have slidable'engagement with the track of a passing car and a circuit for each car inand connected' to its associated contact rail and shoe. w

An electric indicatingsystem for cars travelingon parallel tracks, a contact rail secured to the side of each car, a pair of shoes supporting at opposite ends of each 7 car a circuit including said brushes and contact rail and a source of current connected to said circuit in such a manner as to be arranged in series with the source of current ofanother'car upon engagement between the brushes and rail of one car with the brushes and rail of another car.

4. An electric indicating system for cars traveling on parallel tracks, a contact rail secured to the side of each car, a pair of shoes supporting at opposite ends of each car a circuit including said brushes and contact rail and a source of current connected to said circuit in such a manner as to be arranged in series with the source of current of another car upon engagement between the brushes and rail of one car with the brushes and rail of another car, each of said brushes being so formed as to yieldably engage with the contact rail and compensate for oscillatory movement.

5. An electric indicating system for passing cars comprising car carried mechanism including a contact rail extending the length of the car, a pair of signaling devices one at each end of the car and connecting in series With each other and with said contact rail a pair of brushes electrically connected together and supported one at each end of the car and a generator having one pole connected to the'brushes and its other pole connected to said signaling devices. 7

In testimony whereof I aflix my signature in presence of two witnesses.

ADOLPH KERN.
