UNITED STATES PATENT} OFFICE.
JOSEPH H. GUNN, OF CORTLAND, NEW YORK.
ELECTRIC SIGNAL FOR RAILWAYS.
To all whom it may concern:
Be it known that I, JosErH H. GUNN, a citizen of the United States, residing at Cortland, in the county of Cortland and State of New York, have invented certain Improvements in Electric Signals for Railways, of which the following is a specification.
This invention is an improvement in railway signals, and the primary object of the same is to provide a form. of signaling apparatus or system by means of which the enpoint between the usual signal stations, whereby in the event the engineer of a train should misunderstand a signal at any station. and proceed, or in case the operator at that station should for any other reason desire to signal the train after it has passed. he can display a series of signals between his station and the next to warn the engineer either to stop and return or to proceed under caution.
In the operation of the ordinary block system now generally employed in connect1on with railroads it frequently occurs that through carelessness of an operator, or an error in transmitting telegraphic instructions, a train is permitted to enter a block which is already occupied by another train, and after the second train has assed the station into the block it is impossible, with the system as now in general use, for the operator at that station to stop or signal the train before it reaches the next station. Errors of this kind have resulted in serious accidents by collision of the second train with the first before the latter has passed from the block, and in many instances, if not in all, such accidents could have been prevented if provision had been made for signaling at points between theregular stations and operated. from either or both signal stations of each My invention therefore contemplates the erfection of the ordinary block-system by providing a series of signaling devices between the stations in the nature of emergency signals, which are constructed, arranged and operated in the manner hereinafter described, and what I claim as new and desire to fully protect by Letters-Patent is more specifically set forth in the appendedclaims.
In the accompanying drawings, which form a part of thls specification: Figure]. is l Patented June 9, 1908..
1907. Serial No. 400,041.
a diagrammatic view to illustrate the arrangement of signals in opposite directions from a station. Fig. 2 is an enlarged view of one form of electric signal device. Fig. 3 is a detail view of another form of electric signal device. Fig. 4 is an enlarged detail view of the engaging and releasing means employed in connection with the form shown in Fig. 3.
Like numerals of reference indicate like parts in all the figures of the drawings.
In carrying out my invention I employ a series of auxiliary signaling devices, for instance the incandescent electric-lamps 1, shown in Fig. 1, and locate the same at suitable distances apart along the railroad and at either side of each station, as A, and provide means for operating said signals from said station. When incandescent electriclamps are employed it will be necessary, of course, to install an electric lighting system alqng the road, but in such cases where it is not practical to install an electric lighting system other signaling devices may be employed, such for'instance as those hereinafter described; the main purpose of my invention being to provide a signaling system or apparatus which will permit emergency signals to be displayed along the railroad at different points and operated from the usual signal stations.
W'hen an electric lighting system is employed, as illustrated in Fig. 1, an electricswitch 3 (Fig. 1) is employed and the points arranged so that the lamps at either or both sides of the station may be lighted so as to signal a train that has passed a station, one that is approaching the station, or both simultaneously, according to the' position to which, the levers of the switch are thrown.
The lamps may be supported in any suitable manner along the railroad track, for instance from a cross-arm 5 extending towards the track from an ordinary telegraph pole, as 6; but in case there are no telegraph poles along the road suitable supporting poles may be erected.
The electric lamps preferably show a red I understand them. I tric switch-lever to operate the signals in the of operative position by the engagement of a projecting portion 10 thereof with a spring catch 11 which latter is moved out of engagement with the signal-blade by means of the electro-magnets 12, and when released said signal-blade will slide down and be suspended from the lower end of the pivoted supporting arm, as 13, directly over the track so as to be in full view of the engineer. The electromagnets 12 are supported in a box 9 at the inner end of the supporting-arm, and the catch members are moved to closed position by means of a spring 11 This arrangement is therefore especially adapted for those sections of the country where it is impracticable or too expensive to install an electric lighting system, and may be employed without lamps inasmuch as the headlight of an engine will light up the signalblade so that it will. be seen at night. For this purpose I purpose to locate the signal blade as far over the track as possible, and so that the engineer cannot fail to see it. In employing the electric lamps they are also similarly located. It is purposed of course that a single series of electric lights or signaling devices be provided along the railroad, and that the electric wiring and switchconnections at the several signal-stations be so arranged that the operator at each station will control the lights in both directions from his station.
It will also be understood that in emplo v ing electric lamps and signals they are only operated in case of an emergency or when the customary signal at a station has failed. Therefore the emergency lamps are used independent of the usual signals and the expense of operation will be comparatively small.
The operation of the signaling system herein shown and described will be readily apparent; for supposing the operator at a station A should through carelessness or misunderstood instructions permit a second train to pass his station intov the block ahead while a train was already in that block, and discovered the error after the train passed, he could in such event display the danger signals all alon that block by simply throwing the switchever which. operates said signals, and by this means the engineer of the second train would be immediately warned that there was danger ahead and to proceed with great caution. The same warning signals could be displayed in case a train should ass the usual signals at a station, owing to the failure of the engineer to see the usual signals at said station or failure to properly By operating the elecseries in the other direction from the station a train in that block approaching said station could be signaled to proceed cautiously owing to an impediment at or near said station. Also, in case the conditions require it, the operator may display the signals 1n both directions from his station, so as to warn trains in both blocks of any danger that might be imminent. It will be seen, therefore, that at all times the operator at each station has full control of all trians a roaching and leaving his station and at a ll points between his station and the next in either direction therefrom. This provides, therefore, that a mistake may be corrected without serious accident even if the operator does not discover the mistake until after a train has passed by his station, and which could not be corrected in the operation of the block-systems as now in general use.
In the arrangement shown in Fig. 3 of the drawings, and in the normal position of the parts, the sup orting-arm 13 is disposed at a downward inc ination towards the track and the signal-arm 10 held at the up er end thereof by the catch 1]., so that VV IBD the catch is released the said signal-arm will slide down the supporting-arm and will be located directly over the track and act asa signal. For the purpose of returning the signal-arm to its normal position the pivoted supporting-arm 13 is operated or swung to an opgosite inclination by means of a rod 14 suitab y supported on the post 15. The supporting-post 15 is provided at its upper end with a housing 15 in which the signalblade is concealed. in its normal position.
Having described my invention, what I claim as new, and desire to secure by Letters- Patent, is
'1. A signaling device for railways, comprising signal stations, supporting- )osts located along the railway at suitable istances apart between the stations, a supportingarm on each supporting-post disposed at an inclination towards the track, a signal device slidably mounted on the supporting-arm, means for holding the signal device temporarily at the upper end of the inclined supporting-arm, and means for releasing the signal device, said latter means being operated from the stations.
