ELECTRIC SIGNALING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 568,606, dated September 29, 1896.

Application filed April 21, 1896. Serial No. 588,462. (No model.)

To all whom it may concern.-

' Be it known that I, ADOLPH GARING, of Oarlstadt, in the county of Bergen and State of New Jersey, have invented a new and Improved Electric Signaling Apparatus, of

which the following is a full, clear, and eX- act description.

The object of the invention is to provide a new and improved electric signaling appa- IO ratus more especially designed for use on trolley and other railroads and arranged to prevent head collisions of the cars on single tracks, curves, switches, and the like.

The invention consists principally of an electromagn etat each end of the section and a signal-carrying circuit-wire leading from each magnet to the other end of the section to connect with a ground contact-point adapted to be closed by the armature of the elec- 2o tromagnet at this end of the section, the current passing through said circuit-Wires containing the signals being controlled by a part carried by the car. 4

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims. I

Reference is to be hadto the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a diagrammatic view of the improvement. Fig. 2 is a sectional side elevation of one of the signal-boxes. Fig. 3 is a 5 sectional planviewof the same on the line 3 3 of Fig. 2. Fig. 4 is an enlarged sectional plan view of the motor for actuating the day target-signal. Fig. 5 is an enlarged side elevation of the trolley'wheel, trolley-wire, and 0 hanger. Fig. 6 is a cross-section of the same. Fig. 7 is a cross-section of the trolley-wire and part of the hanger, and Fig. 8 is a diagrammatic view of the improvement as arranged for turning out the electric lamps at 5 both ends of the sections when the cars leave the latter.

The signal-boxes A A, both alike in construction, are set up at the ends of the section, for instance, as illustrated in Fig. 1, at

the turnouts B B, located at the ends of the section B which latter forms part of a trolley-railroad. Each of the signal-boxes A A contains a night-signal in the shape of a red electric lamp O O respectively, for indicatin g danger and a white electric lamp 0 O 5 5 respectively, for indicating safety. The boxes also contain day-signals in the shape of targetsD D, respectively, adapted to be given quarter-turns for indicating safety and danger positions, as hereinafter more fully described, the said targets being actuated by electric motors in the form of field-magnets D D respectively, made circular and containing an armature D, secured on a shaft D mounted to turn in suitable bearings and supporting at its upper end the targets.

In the boXAare formed two compartments, one of which contains the red electric lamp O and the other contains the white electric lamp O, the rays of the lamps when lighted passing through suitable lenses to the outside to be visible by the motorman on the approaching car. The other signal-box A is similarly arranged with compartments, one of which contains the red electric lamp O and the other the white electric lamp 0 In the upper ends of the signal-boxes AA (see Figs. 1 and 2) are arranged electromagnets E E, respectively, having armatures E E respectively, in the shape of levers mounted to swing up when attracted by the magnets, and adapted to dt'op when the electromagnet is rendered inactive. The armature-E when attracted by its electromagnet E, makes contact with two contact-points'F F, and when said armature drops it makes contact with two contact-points F F of which the latter is connected with the ground G. The other armature E when attracted makes contact with eontact-points F F and when the elec- 9o tromagnet E is inactive and the armature drops then it makes contact with the contact-points F F, of which the latter is connected with the ground G.

The electromagnetEis connected byawire 9 5 H with ahanger I, straddling the trolley-wire B at the turnout B, said hanger being insulated from the said trolley-wire and adapted to be engaged by a trolley-wheel]; when the car travels through the turnout in the direction of the arrow a. IVhen this takes place, the trolley-wheel 13 sends a momentary current through the hanger I and wire 11 to the clectromagnet E, so as to energize the same and cause the magnet to attract its armature 11 as indicated in Fig. 1. The other magnet E is connected by a wire II with a similar hanger 1, straddling the trolley-wire B at the turnout B, said hanger I being adapted to be engaged by the trolley-wheel of a car traveling through the turnout B in the inverse direction of the arrow a. The wire II is connccted by a wire II with the contact-point F, and a similar wire 11 connects the wire 11 with the contact-point F The electromagnet E is also connected with a circuit-wire J, containing the white electric lamp in the signal-box A, said wire then extending to the other end of the section to the signal-box A, and there contains the red electric lamp C, and then connects with the contact-point F. A circuit-wire J connects with the electromagnet E and contains the white electric lamp 0 in the signal-box A, and extends from this lamp 0 to the other signal-box A and there contains the red electric lamp 0, and then makes connection with the contactpoint F A branch wire J 2 leads from the wire J in the signal-box A to one end of the field-magnet D connected at its other end with the circuit-wire J, as plainly indicated in Fig. 1.

' A similar branch wire J leads from the wire J in the signal-box A to one end of the fieldmagnet D the other end of which is connected to the circuit-wire J.

Now when the device is arranged on a trol ley-railroad, as shown in the drawings, then the electricity necessary for lighting the lamps O C O C and that required for working the motors and giving quarter-turns to the tar get-signals is directly supplied from the trolley-wire B and for this purpose the same is connected by a live wire K with the contactpoint F in the signal-box A and by a live wire K with the contact-point F in the signal-box A. The free ends of the armatures E and engage vertically-disposed insulated rods L L, respectively, fitted to slide in suitable bearings in the signal-boxes A A and pressed on at their upper ends by springs L L, respectively, for holding the said insulated rods normally in a lowermost positionthat is, when the armatures E and E are disengaged from-their electromagnets. Vhen the armatures, however, are attracted, then the rods L L are pushed upward to make contact between the springs L and L and the contact-points L L, respectively, connected by wires N N, respectively, with the contact-points F and F", respectively. The

springs L and L" are connected by wires 0 O with the contact-points F and F respec- This arrangetivel 7 as indicated in Fi 1.

went serves for grounding the electric lamps after the current is cut oil.

Each hanger I I is provided with a fork I straddling the corresponding wire, as plainly shown in Figs. 5, (3, and 7, said fork being fulcrumed on an arm 1 secured to a support carrying the trolley-wire, the latter being insulated from said support in the usual manner, and consequently insulated from the hanger I or I.

The operation is as follows: lVhen a car passes the turnout B on the wire B in the direction of the arrow a, then the trolley-wheel of this car makes contact for an instant with the fork I of the hanger I, so that a current of short duration is sent through the hanger I and wire II to the electromagnet E to energize the latter and cause the magnet to attract the armature E, as illustrated in Fig. 1. \Vhen this takes place, the armature E in moving in contact with the contact-point F causes a current to pass from the trolley-wire 15 by the wire K to the contact-point F, the armature E the electromagnet E, and the wire J to light the white lamp 0 in the box A and the red lamp (1 in the box A, the current passing by way of the contact-point F, armature E and contact point F to the ground G. Now it will be seen that at the turnout B the white lamp 0 is burning, thus indicating safety fora following car, but at the same time danger is signaled by the red lamp 0 in the box A to a car approaching this section in the inverse direction of the arrow at. \Vhen the car traveling in the direction of the arrow a has finally arrived at the turnout 13, then the car going in the inverse direction can start into the section, and in doing so the trolley-wheel B in passing over the wire 13 makes a momentary contact with the fork 1 of the hanger I,and thereby sends a current of short duration through the wire H to the electromagnet E, so that the armature E is attracted. \Vhen this takes place, th e burning white lamp 0 and the burning red lamp C are instantly extinguished, as the circuit for those lamps is broken by the armature E leaving the corn tact-point F connected with the ground G. The moment that the circuit of the wire J is broken the electromagnet E is rendered inactive, and consequently the armature E drops and makes contact with the points F and F and disconnects the points F F. The armature E in making contact with the points F" F causes a live current to pass from the trolley-wire by the wire K through the contact-point F and armature E to the electromagnets E, which thus keep the armature E attracted, and the current passes through the wire J to the white lamp 0 in the box A, and to the red lamp 0 in the box A, so that the two lamps C and O are lighted to display safety at the end B of the section 13 for cars followin gin the inverse direction of the arrow (4 and to display danger for cars traveling to the end B of the section B in the direction of the arrow a. Thus the car can travel over the section B in the inverse direction of the arrow at until it finally reaches the turnout to pass into the next following section and permit another car to pass over the turnout B to the section B in the direction of said arrow a. When this takes place, the abovedescribed operation is repeated; that is, the trolley-wheel of this car makes momentary contact with the hanger I to cause the electromagnet E to again attract its armature E and to break the current at the contact-point F for the circuit previously passed through the wire J. The armature E then drops back to its normal position (shown in Fig. 1) to make a ground contact for the live current passing through the wire J, as previously explained.

During the day the lamps C O C C are cut out in the wires J J by a suitable switch, and the wires are connected by a similar switch with the branch wires J 2 J so as to actuate the motors controlling the day target-signals D and D. As the targets make quarter-turns they all stand alternately in danger and safety positions to give signals the same as the red and white lamps burning during the night. It is understood that when a current passes through the circuit-wire J or J then the electric motor for the corresponding day-signal is energized to set the target accordingly, and when the current is cut off then a light spring or equivalent device returns the armature andtarget to the normal previous position.

When it is desired to cut off or turn out the lights when the car leaves the section in either direction, then I prefer the arrangement illustrated in Fig. 8. In this case the two signalboxes A and A at the end of the section B at the turnouts B B are provided with electromagnets E E and with an additional set of electromagnets P P, located in said boxes A A respectively.

The electromagnets E E are connected by the'wires H H respectively, with the hangers I 1 respectively, and the said electromagnets are also connected with the circuitwires J 4 J respectively, of which the wire J4 contains the white lamp 0 in the signal-box A and the red lamp 0 and the day-signal D in the signal-box A The other circuitwire J 5 contains the white lamp 0 in the box A and the red lamp 0 and day-signal D in the box A The wire J 4 connects in the signal-box A with the end of the armature-lever P for the electromagnet P, said armature being adapted to make contact with the point F connected with the ground G The Wire J 5 connects in the signal-box A with the pivot of the armature P for the electromagnet P, and this armature, when in a lowermost position, makes contact with the point F connected with the ground G The electromagnets P P are connected by Wires Q Q with hangers I 1 respectively,

arranged in the trolley-wires at the turnouts B B for the cars leaving the section B The electromagnet P is also connected by a branch wire Q with the circuit-wire J and a similar branch Q connects the electromagnet P with the circuit-wire J Now it will be seen that when a car travels in the direction of the arrow 1) its trolleywheel, by contacting with the hanger 1 causes the white lamp 0 to be displayed in the box A and the red or danger lamp 0 to be displayed in the box A When this car leaves the section at the turnout 13", its trolley-wheel comes in contact with the hanger I and a momentary current is sent through the wire Q to the electromagnet P, so that the armature P is attracted and the ground connection for the circuit-wire J 4 is broken, so that the lamps C C are extinguished. The same operation takes place when a car travels in the inverse direction of the arrow 1), as this causes the white lamp 0 and the red lamp 0 to be lighted by the trolley-wheel actuating the hanger 1 When this car leaves the section at the turnout B the trolley-.

wheel comes in contact with the hanger I, and consequently a current passes to the electromagnet P, which then attracts the armature P to break the groundiconnection for the circuit-wire J containing the lamps C and 0 It is further understood that the electricity for the lamps and motors for the day-signals may be supplied from some local source instead of from the trolley-wires, as previously explained in reference to Fig. -1.
