SIGNALING DEVICE FOR APPARATUS FOR STOPPING VEHICLES.
Patented Feb. 8, 1916.
Application filed May 14, 1915. Serial No. 28,119.
To all whom it may concern Be it known that I, JOHN J. KEENAN, a citizen of the United States, and a resident of New York, county and State of New York, have invented a certain new and useful Improvement in Signaling Devices for Apparatus for Stopping Vehicles, of which the following is a full, clear, and exact specification.
This invention relates to a class of signals designed to be used in conjunction with the apparatus for stopping vehicles as disclosed in my pending application for a patent, serially numbered 820,645, filed February 24, 191 1, and has for its object primarily to provide for the employment in the station of each of the said apparatus a device whereby an alarm may be quickly sounded so that one of the next apparatus on either side thereof may be operated for stoppin an automobile or other vehicle in event of the vehicle passing one station following the oc' currence of an accident or when the vehicle is traveling faster than a given speed.
Other objects of the invention are to provide in each station a source of current supply;-to provide an alarm in each station; to provide an electric circuit leading from the sources of supply to all of the alarms; and to provide means for opening and closing the circuit at each station 1n emergency whereby the alarm at the station in front of the traveling vehicle may be sounded to permit the apparatus of this alarm to be timely operated for stopping the vehicle should one apparatus fail to operate, or should the vehicle pass before the apparatus isactuated.
A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification in apparatus s owing the signaling device applied thereto, and Fig. 3 is an enlargeddialowing station.
I grammatic view of a number of the signalingdevices.
In practice any suitable number of the signaling devices 10 may be employed, and all of the devices are correspondingly constructed as well as being adapted to be opera-ted in a similar manner. One of the si operating in emergency the guard members 15 arranged across a highway, as 16, as described in the hereinbefore referred to application for a patent for apparatus for stopping vehicles.
Each of the signaling devices has an electrically operative alarm, or bell 17 which may be of any well known form, and one of these alarms is provided in the postl3 of each of the stations 11. In each of the stations 11 is a battery, or other suitable source of electric current supply, as 18, and also in each station is a manually operative switch 19 of a suitable make adapted to be alternately swung into engagement with one of two contacts 21 and 22. In order to sound the alarm at the station in front of a traveling vehicle so that the apparatus may be timely operated should an apparatus fail to operate, or should the vehicle am before it is actuated, an electric circuit 23 is provided for sounding the alarm. The electric circuit 23 includes a wire 24 leading from one terminal of each of the batteries 18 to the switch 19in each of the stations, and from the second terminal of the battery in each station is a wire 25 connected to a main wire 26. A wire 27 leads from the wire 26 to one pole of the alarm 17 of each of the stations, and from the second pole of each of the alarms is a wire 28 leading to'a second. main wire 29 which is connected to the Wire 25 of the battery of the next fol- To the contact 21 in each station is connected a wire 30 leadin to one of the poles ofthc alarm 17 of t e next preceding station, and connected to the contact 22 in each station is a wire 31 leading to the other pole of the alarm in the next following station.
To operate the signaling device in emergencyfonrstoppin'g atraveling vehicle in engagethe contact 21 the circuit, as indicated iirdotted lines atl Fig. 3, will be closedfrom the battery 18 of this station overthe wire 25, through the second main wire? 29, over the wire 28 of the next preceding-station, through the alarm 17 of this station, over the wire 31 to the contact 21 and through-the switch of the first station, and over the wire 24 leading from the battery of the first station. The alarm in the next preceding station will thereby be sounded for giving warning to operate the apparatus thereof. When the switch of the station is moved into engagement with the contact 22 the circuit, as shown'in dotted lines at 2 Fig. 3, will be closed from the battery of this station over the wire 25, over the main wire 26, and over the wire 27 of the next following station. The currentwill then pass through the alarm of this station, over the wire 30, to the contact 22 and through the switch of the first station, and over the wire 24 leading from the battery of the first station. In this manner the alarm may be sounded in any station following the one in which the signaling device is operated.
In the foregoing description, I have embodied the preferred form of my invention, but'I'do not-wish to be-understood as limit ing'mys'el'f thereto, as I am aware that modifications may be made therein without departing-from the principle, or sacrificing any "of "the advantages of this invention,
therefore I reserve to myself the right to makesuch changes as fairly fall within the scope of the appended claims. Having'thus described my invention, I 'claimas new anddesire to secure byLetters Patent I 1. A "signaling system for regulating tra'ffic with apparatusfor stopping vehicles,
, comprising a plurality of stations, an alarm in each station, a normally open circuit leading to all of thealarms, and means in each station for closing the circuit whereby the alarm in either the next preceding orrthe station for closing the circuit whereby the alarm in either the next preceding or the next following station may be sou ded in emergency so that the apparatus of the station 'may be' operated, forthe purpose" specified.
3. A signaling system for regulating traffic with apparatus for stopping vehicles, comprising a plurality of stations, analarm in each station, a battery in each station in cluding the alarm, a normally open circuit I leading from each battery to all of'thealarms, and means in each station for clos- I ing the circuit whereby the alarm in either the next preceding or the next following station may be soundedi'n emergency 50 that the apparatus of the station may be operated, for the purpose specified.
4. A signaling system for regulating traffic with apparatus for stopping vehicles comprising a plurality of stations, an'alarni in each station, a battery in each station, including the alarm, a normally open circuit leading from each battery to all of the alarms, and a switch in each station for closing the circuit whereby the alarm in either the next preceding or the next following station may be sounded in emergency so that the apparatus of the station may be operated, for the purpose specified.
This specification signed and witnessed this thirteenth day of May, A. D. 1915.
