RAILROAD SIGNALING.
Specification of Letters Patent.
Patented Dec. 19, 1905.
Application filed October 14, 1905. Serial No. 282,821.
To all whom it may concern:
Be it known that I, IsIDoR KITsEE, a citizen of the United States. residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Railroad Signaling, of which the following is a specification.
My invention relates to an improvement in railroad signaling. Its object is to provide a simple and efficient means whereby the person in charge of a train or vehicle is made aware if his section of the rails of travel is clear or occupied by a second train or vehicle or if the rails are otherwise connected together either purposely or accidentally.
Referring to the drawings, Figure 1 is a side elevation of a stretch of road-bed, show ing one complete block or section and the beginning and ending of two others, showing a train entering one section before another train has left the same. Fig. 2 is a plan view of Fig. 1, showing the train and apparatus in the cab of the locomotive in diagram. Fig. 3 is a plan view of a stretch of road-bed including one complete block or section and a portion of two more sections, showing the contacts arranged as they would be on a singletrack railway. Fig. 4 is a side elevation of the front portion of a locomotive, a portion of the cow-catcher being broken away to show the spring-contact carried by the same. Fig. 5 is a plan view of Fig. 4, the parts of the locomotive being all removed, except the wheels and contacts, the electrical apparatus carried in the cab of the locomotive being illustrated in diagram. Fig. 6 is a plan view of the spring-contact carried by the cowcatcher of a locomotive extending outward from the inside of same to make contact with vertical posts.
A and B represent the two tracks of a railroad, the track B being divided into blocks or sections, each block or section being electrically insulated one from the other. The track A is continuous and not divided into blocks or sections, so that said track is an block or section, and at one end the contacts will be to one side of the center near the rail A, and at the other end they will be to the other side of the center near the rail B, both of said contacts in electrical connection with the same block or section of the rail B. These contacts C are made of metal suitable for conducting electricity.
Arranged upon each locomotive in advance of the front wheels of the same and preferably attached to the cow-catcher, as shown in Fig. 4, is the spring contact-shoe D, adapted to make electrical connection with the contact C when in the proper position. In the drawings I have shown the shoe D as to be connected by means of the parallel links E, which are held vertically by the spring F for the purpose of holding the shoe D normally downward in its extreme lowest position. Should through the moving of the locomotive the shoe D come opposite the stationary contact C, it will strike this contact, and the links E will allow the shoe D to swing in a manner so as to 'slide over this stationary contact C; but it is obvious that any other mechanical arrangement may be substituted for that shown in the drawings, the essential feature only being that the contacting should be positive and the shoe shall always remain in electrical connection with its circuit. In the drawings the shoe D is illustrated as to be divided into two parts D and D insulated from each other. Located in the cab of the locomotive is a battery or other source of electricity G, an electric bell H, a magnet I, an armature J, a spring-catch K, a contact L, and a one-stroke bell M.
The portion D of the shoe D is in electrical connection with one terminal of the battery G, the other terminal of the battery Gr being connected to the magnet I, and said magnet I is also connected to the body of the locomotive, so that when the shoe D passes upon one of the contacts C and there is a train upon the same block to which the contact C is connected a circuit will be formed from the battery to the shoe, to the contact 0, through the section of the rail B to which the contact is connected, through the truck of the train ahead to the rail A, from the rail A through the truck of the locomotive, to which the shoe is connected, through the magnet I, back to the other terminal of the battery G, thus attract ing the armature J, and when said armature J is attracted by the magnet it will be engaged by the spring-latch K, which will hold IIO it in its attracted position until released, and when in this position it will make contact with the contact-point L, and as the armature is in electrical connection with one terminal of the battery G and an electrical connection extends from the other terminal of the battery G through the electrical bell H to the contact L said bell H will continue to ring until the armature J is released by retracting the spring-latch K, and thus although the contact between the shoe D and the contactpoint C will be very short still the engineer will have a continuous alarm and cannot avoid heeding the same. Of course instead of an audible alarm an electric light or other visible alarm could be used, if desired.
In order that the engineer may have evidence that the electrical connections are all in order each time. he passes upon a new block or section, I provide the one-stroke gong M or a visible alarm, if so desired, within the cab. This alarm M is electrically connected with the part D of the shoe D and is also connected with one terminal of the battery G, and as the other terminal of the battery Gr is connected with the other portion D of the shoe D each time'the shoe passes over the contact G and by so doing establishes an electrical connection between the two parts of the shoe D the alarm M will be actuated, thus notifying the engineer that the electrical connections are in order.
Fig. 6 shows a device that could be used where it is desired to employ upright posts N, arranged alongside of the track instead of contacts between the rails. This would operate in exactly the same manner and would probably only be used in cases Where considerable ice and snow is formed upon the track.
