AUTOMATIC SIGNAL SYSTEM FOR RAILWAYS.
This invention relates to a new and useful automatic mechanical inter-lock signal system, adapted mainly for use on railways, which comprises a track running north and south, which is crossed approximately at right angles thereto by an east and west track; this system is applicable to double tracks running in the saine directions, with the exception that various parts are to be duplicated, in order to attain the desired result. The system may also be applied to a single track running in any desired direction.
The invention in its broadest scope aims as its prir. iry object to provide means adjacent each track to be operated by the flanges of the engines wheels, so as to throw the signals on the intersecting track.
- A further object ofthe invention is to provide automatic means for locking the signals in the positions in which they are thrown, and after the train,.if south hound has passed the crossing, means are provided to be actuated by' the wheels flanges, to unlock the signals, thereby permitting them to be returned to their normal position.
One of the features of the invention is the provision of a bar having a universal connection at its stationary point between the rails, so as to permit the bar to be separated from one of the rails, when perating one set of signals, and to be pressed downwardly by the flanges of the wheels, after the train has passed the crossing, and is continuing on its way.
A further feature of the invention is the provision of a plurality of hell crank levers, so connected with the signal mechanisms of the east and west north and south intersecting tracks, so that the signals on the east and west track will be thrown at danger, when a train bound south or north is approaching the crossing or the intersecting of the tracks.
The invention comprises further features 7 Specification of Letters Patent.
latented Apr. 30, 1912 Application filed October 18, 1911. Serial No. 655,445.
and combination of parts, as hereinafter set forth, shown in the drawings and claimed.
In the drawings :-Figure 1 is a plan view of a railroad crossing, showing the improved automatic mechanical inter-lock signal system as applied thereto, the same being constructed in accordance with the invention. Fig. 2 is a detail perspective view, showing how one of the bell crank levers is locked, which holds the signals at danger until the train has entirely passed the crossing, after which the locking mechanism is unlocked. Fig. 3 is a detail perspective View of the bar, which is operated by the flanges of the wheels, which bar is provided with a' universal connection to a stationary point. Fig. 4 is a sectional View 011 line 44 of Fig. 3. Fig. 5 is a sectional view on line 55 of Fig. 3.
Referring more especially to the drawings 1 designates the tracks or rails running north and south, which intersect or cross the rails 2 running east and west. The crossing of the rails is indicated by the nunieral 3. The crossing is supported on the intersecting ties'4 and 5, in the ends of which bifurcations (3 are formed. Mounted in the arms formed by the bifurcations are' pivot pins 7 on which the bell crank levers 8, e 9, a 10,10 11 and 11 Arranged at a adjacent one of the rails, at each end of the north and south track is a signal throwing bar 12, while at the points I) of the east and west track a similar bar 13 is disposed. These bars 12 and 13 at. one end are provided with universal connections 14 to the raised portions 15, as shown, so as to permit the bars to be swung sidewise, or downwardly. Pivotally mounted at 16 and 17 to the ties '18 and 19 are the bell crank levers 20 and 2l, bet-ween each of which and each of the bars 12 rods 22 and 23 are connected. Pivotally mounted on the ties 24. and'25 of the east and -west track are the bell crank levers 26 and 27. Connecting between each of the bill are mounted. T he upper ends of the shafts nected between the cranks of the shafts and one of the rail ties, so as to return or. signals to their normal position, after ha ving been unlocked.
Conncctingbetwcen one of the arms of the bell crank lever and one of the arms of the bell crank lever 8 is the cable 44-, while connecting between the crank 35 and the bell cranklever 8 is a cable A cable 46 is connected between the bell crank levers 27 and 9 11. cable 417 is connected between the arms of the bell crank levers 8 and 9, while a cable" $8 connects between the bell crank lever 8 and the bell crank lever 11. The lever 11 is in turn connected to the crank 38 by virtue of the cable 4-9.
. The cables a0 and 51 are connected between one of the arms oteach of the levers 10 and 11 and 11 and 10, while a cable 52 connects between one arm of each of the bell crank levers 9 and 10. A cable 53 con nccts between the bell crank lever 9 and the bell crank lever 10 while the cable 54: is conmaeted between the bell crank levers S and 1 1. Connecting between the bell crank levers 8 and 9 is a cable The cranks 36, and 37, are each connected to one ot the arms of each of the bell crank levers 9, and It), by meansot the cables 56 and 57. .1 cable 58 connects the bell crank lever 21 and the bell crank levcr 10, while a similar cable 59 connects between the bell crank lever 26 and the bell crank lever 11. Movable with each of the Jcllcrank levers 8, 9 10 and 11 arc the usual form of nals 60, which indicates to the engineer on any traina-nnning east or west, or north or south that, the signals on the track running at right angles have been operated.
Projecting from the tie 5 is a frame 61, having a bell crank lever 62 pivoted therein as at 63, one end of which bell crank lever engages beneath the bell crank lever 10 there being a spring (t1 holding this bell crank lever 62 normally against the underncath side of the lever 10. However, just so soon the bell c ank lever 21 is rocked 'on its pivot by the signal throwing bar 12,
thus actuating the bell crank lever 10 in the direction of the arrow 65, the arm 62 of the bell crank lever 62 is thrown in the path of the lever 10", thus locking the Sig:.-
oaders normal position, which is clear. This lock and release mechanism for the signals may be equipped on each side of the crossing on each north and south, east and west tracks, if desired, so that trains running either north or south, east or west may lock the signals and then release them.
A train'bound south will throw the signals on the ast and west tracks, by actuating one of the bars 12, which in turn actu- .ate the bell crank levers 9, 10 and 11. When a train is passing the crossing bound north the signals of the east and west track are thrown at danger, by the actuation of the other bars 12, which in turn actuate the bell crank levers 20, 8, 9, and 11. A train bound west will throw the signals of the north and south track at danger by actuating one of the bars 13, which in turn oscillate the bell crank levers 26, 11, 8, and 10, while a train bound cast will throw the signals of the north and south track at danger by operating the other bar 13, thus in turn actuating the bell crank levers 27, 9*, 10 and 8.
