ELECTRICAL APPARATUS FOR CONTROLLING SlGNALS.
SBEGIFIGATION forming part of Letters Patent No. 529,059, dated November 13, 1894.
Applicationfiled December 11, 1893. Serial No. 498,329. (No model.)
To all whom it may concern.-
Beit known that we, SAMUEL S. BOGART, residing at Schraalenburg, in the county of Bergen and State of New Jersey, and MICHAEL B. LEONARD, residingat Richmond, in the county of Henrico and State of Virginia, citizens of the United States, have invented certain new and useful Improvements in Electrical Apparatus for Controlling Signals; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.
Our invention relate to improvements in interlocking block signaling apparatus adapted especially for use in controlling semaphore or other visual signals.
Primarily the object of the invention is to provide signaling devices at each station connected bya main line which is adapted for use for both telegraphing and signaling purposes.
A further object of the invention is to provide simple and efficient means for locking the signals directly instead of locking them through intermediate controlling devices as has been done heretofore.
The invention consists in the features of construction and combinations of devices hereinafter fully described and clearly defined in the appended claims.
Referring to the accompanying drawings, forming a part of this specification, Figure 1 isa diagrammatical representation of aninterlocking block signaling system between two block offices or stations, embodying our invention, the parts being in normal position for telegraphing. Fig. 2 is a similar view showing one of the switches pulled down to release the signal at the distant station. Fig. 3 is a diagram of a modification in which the circuit of the unlocking magnet is extended to include a signal lever; and Fig. 4 illustrates a furtherv modification. 4
A and B indicate two block stations, connected by a main line wire C, provided at each station with a Morse relay D, sounder E, and key F, the key having three instead 5e of two points.
, telegraphing.
a and 1), indicate semaphore signals located respectively at the stations A and B. Thes semaphores, as will be observed, are unprovided with the usual signal levers, and are designed to drop by gravity after being released by the electrical means hereinafter described, and to be returned to their normal or locked position by hand through suitable pull-cords G. Each of the signals a, and b, is provided with a lug or catch H, at its pivoted end adapted to be engaged by an armature pawl I, pivotally supported adjacent to a magnet K, to be attracted thereby when the latter is energized. Each of the magnets K, is included in a local battery circuit comprising a battery 00, wires to, and a polarized relay 00 Each terminal of the main line C, is provided with a circuit closer c, and with a spring switch L, which serves when in normal position (as shown in Fig. 1) to ground the main line through the battery M. B. for These switches each consist of a pull rod Z, provided at its upper end with a spring Z, and at about equidistant points throughout its length with cross arms Z Z and Z serving as contact points. The points 1 and 1 are connected with the terminals of the main line battery, M. B. while the point Z is connected with the ground wire m, and the point Z4, with the ground wire m The polarized relay circuit is normally grounded through the spring switch and wire mi.
The operation of the mechanism will now be described.
As shown in Fig. l the parts are in position for telegraphing, the circuit being traced as follows by reference numerals:From the ground wire m, through Z to the main battery, thence through arm Z and conductor 4:, to key F, the depression of the key passes the current to the main line C, thence through the telegraph relay D, at station B, and thence through conductors 6, 7,8, 9, 10 and m, to ground.
current thus used for telegraphic purposes will not affect the polarized relay at B, (and consequently will not release Bs signal) in asmuch as said relay is adjusted to respond only to a reversed current from As battery, 10
It will be understood that the 5 or to a change in polarity of said battery. To release the signal at B, the operator at A pulls down the switch L, to the position shown in Fig. 2. This results in breaking the ground 5 connection of As relay circuit at the point 11, and throws the relay into the mainbattery circuit, so that the current will pass through the following circuit from ground wire at through 12 and 13 to the battery, through 14, 15 and 16, to the main line and through 17 to Bs relay and thence through 18, 19 and 20 to ground. The electro-magnet at B is thus energized and the armature pawl withdrawn to release the signal. It will be 15 observed that in the circuit last traced the current is of opposite polarity from that used for telegraphing, and the relay at B is adjusted to respond only to such reversed current. The switch L at station A is automatizo cally retracted when released by the spring 2 to return the connections to their normal position. The signal at A is operated from station B in like manner, the connections and construction being similar to those at the station A.
In Fig. 3 we have shown an extension of the polarized relays local circuit to include a signal lever N, provided with a lug n. adapted to be engaged by a pawl 71. This lever N is connected by pull-wires 0, and a bell-crank lever 19, with the semaphore. This modified construction is designed for use only where the semaphores are provided with operating levers, and it is not intended to lock 5 both the signal and the signal lever at the same time.
It will be understood that the operation in the modification is substantially similar to that above described, the difference being 0 that in the one case the semaphore is directly locked, while in the other the locking pawl engages the operating lever. It may also be desirable in some cases to use a locking bar P (Fig. 4) connected to the semaphore by a 4 5 pivoted rod 19, and an intermediatebell-crank p, and having a notch 19 for engagement by the armature pawl; the semaphore being connected on the opposite side of its pivot with a rod 19 connecting by intermediate bell- 5o cranlg p and rod 19 with the operating lever Having thus fully described ourinvention, what we claim as new, and desire to secure by Letters Patent of the United States, is-
