ELECTRICALLY-OPERATED RAILWAY CROSSING AND SIGNAL.

Application filed. February 21, 1918.

To all whom it may concern Be it known that I, HARVEY J. YAGER, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Electrically-Operated Railway Crossings and Signals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in electrically operated railway crossings and signals and has for one of its objects the provision of a device of this character, whereby the frogs of the crossing maybe electrically actuated, so that they will be properly positioned for one track and then the other, and simultaneously illuminating signaling lights along the track to indicate which track of the crossing is open for a train or car to cross or proceed.

Another object of this invention is the provision of means located adjacent the crossing whereby the operation of the frogs and signal lights may be readily controlled and which signal lights are automatically controlled by the frogs moving into their different positions. j

A further object of this invention is the provision of an electrically operated railwaycrossing and signal of the above stated character, which shall be simple, durable and efficient, and which may be manufactured and sold at a comparatively .low cost.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which:

means for actuating the frogs and for illuminating and controlling the signal lights, and

Fig. 3 is a sectional view illustrating the electrical means for actuating the locking means to the arm.

Referring in detail to the drawings, the numeral 1 indicates as an entirety a railway crossing consisting of the track A and the track B. At the intersection of the tracks A and B, are positioned oscillatory frog members which have grooves 3 adapted to be alined with the grooves of the tracks so as to form a continuous track at the crossing, thereby obviating the jars and jolts now frequent to cars or trains when passing over crossings of the ordinary type. The grooves 3 have secured to their lower ends segments 4, which segments mesh with segments 5 carried by arms 6 and 7. The arms 6 and 7 are pivotally mounted as illustrated at 8 for oscillatory movement and are connected to each other in any well known man ner whereby upon movement of one arm, a similar movement will be transmitted to the other arm. The pivotal point of the arm is upon a suitable supporting structure 9, and which supporting structure underlies the arm 7 The arm 7 is the operating arm for all of the frogs and has secured thereto electromagnets 10 and 11 upon opposite sides of the pivot 8 as clearly illustrated in the drawings. The electromagnet 10 has a winding a and the electrical current is adapted to extend through this winding in the direction indicated by the arrows to establish a south pole in the direction of one free end of the arm 7 and a north pole in the direction of the pivot 8. The electromagnet 11 is provided with a winding 6 and the electrical current passes through this winding 6 in the direction indicated by the arrows so-as to establish a north pole adjacent the pivot 8 and a south pole in the direction of the other free end of the arm 7. The magnets 10 and 11 are secured to the arm 7 by fasteners 12. A pair of electromagnets 13 and 14 are secured to the supporting structure 9 adjacent the electromagnet 10 and are arranged in the arc of a circle as clearly shown in the drawings. A similar pair of electromagnets 15 and 16 are carried by the supporting structure 9 adjacent the electromagnet 11 and are also arranged in the arc of a circle. The electromagnet 13 is provided with windings 0 and e which windings extend in opposite directions and the electromagnet 14 is provided with oppositely extending windings c and e. The electromagnet 15 is provided with oppositely extending windings c and e and also the electrolnagnet 16. The pairs of electromagnets being provided with double windings and which windings extend in opposite directions of each other for the purpose of reversing the poles of the magnets during the operation of the frogs.

Located adjacent the crossing 1 is an observation tower or building 17 in which is positioned a double pivoted knife, switch 18. Feed wires 19 and 20 lead into the tower 17. Contacts 21, 22, 23 and 24 are located in pairs upon one side of the pivot point of the switch 18 while contacts 25, 26, 27, and 28 are located in pairs upon the other side of the switch 18. The contact 28 has the feed wire20 connected thereto while the contact 22 has the feed wire 19 connected thereto. A conductor 29 is connected to the feed wire 20 and to the contact 23. A conductor 30 is connected to the feed wire 19 and to the contact 25. Double knife switch 31 and 32 are located adjacent the knife switch 18 which is the main controlling switch. The switch 31 has associated therewith contacts 33 and 34, respectively, while the switch 32 has associated therewith contacts 36 and 37. The contacts 21 and 33 are connected by a conductor 38 while the contacts 34 and 24 are connected by a conductor 39. The con tacts 26 and 36 are connected by a conductor 40, while the contacts 27 and 37 are connected by a conductor 41.

A pair of magnets 42 and 43 are carried bythe supporting structure 9 adjacent the electro-magnets 15 and 16. A frame 44 is carried by the supporting structure 9 and overlies the electro- magnets 42 and 43 and has slidably mounted therein spring actuated catches 45, each provided with an armature 46 adapted to be attracted by the mag nets 42 and 43 so as to move the catches 45 against the tension of the spring. The catches 45 are adapted to engage in notches 47 in the under face of the arm 7 for holding the frogs 2 against accidental movement when in either of their operative positions or with the grooves 3 thereof in alinement with the grooves of the tracks A and B. A conductor 48 is connected to one sleeve of the switch 31 and to the magnet 42. conductor 49 is connected to the magnet 42 and to one end of the winding 0 of the magnet 15. The other end of the winding 0 of the magnet 15 has connected thereto a conductor '50 which isconnected to one end of the winding 0 of the electro-magnet 16. A conductor 51 is connected to the other end of the winding 0 of the electro-magnet 16 and to the end of the winding Z) of the electromagnet 11. It will therefore be noticed that the electric current passing through the winding 0 in the direction indicated by the arrows of the magnet 15, a north pole will be established at the end of said magnet adjacent the magnet 11 and south pole established at the end of the magnet 16 adjacent the magnet 11, whereby the magnet 11 will be attracted by the magnet 15 and be repelled by the magnet 16. The conductor 52 is connected to the other end of winding 5 of the magnet 11 and to one end of the winding a of the magnet 10. A conductor 53 is connected to the other end of the winding a of the electromagnet 10 and toone end of the winding 6 of the electro-magnet 13. A conductor 54 is connected to the other end of the winding 6 of the electromagnet 13 and to one end of the winding 6 of the electro-magnet 14. A conductor 55 is connected to the other end of the winding 6 0f the electro-magnet 14 and to the other sleeve of the switch 31, whereby upon having the switch 31 in engagement with the contacts 33 and 34 and the switch 18 in engagement with the contacts 21 and 24, the frogs 2 will be rotated into a position as illustrated in Fig. 1 so that the grooves 3 thereof aline with the grooves of the track A. As soon as the magnet 42 is energized, its respective latch 45 is disengaged from the arm 7 for permitting the same to move into a position as illustrated in Fig. 1. By having the electric current pass through the windings of the electro1nagnets 13 and 14 in the heretofore described manner establishes a south pole at the end of the magnet 13 adjacent the magnet 10 and a north pole at the end of the magnet 14 adjacent the magnet 10, whereby the electro-magnet 13 will attract the magnet 10 and the electromagnet 14 will repel the electro-magnet 10 and which means coiiperates with the heretofore described magnets in moving the arm 7.
