- FIG. 1 represents the rails of a railway-track, at each side of which a series of signaling-boxes 2 are located, as best shown in Figs. 1 and 7
- Each of these signaling-boxes 2 is provided on the side farthest from the track with a raised extension 3, the part 4 of the box being materially lower than the part 3, as shown in Figs. 2 and 10.
- Each box is provided with a signal-conveying arm 5, pivoted at 6 near one end of the box and adapted to be lifted through a slot 7 in the top of part 3 to an angular position, as indicated by dotted lines in Fig. 10.
- a signal-setting arm is pivoted at 11 in the part a of the box and normally projects upwardly in an annular position through a slot 12 in the top of the box, Figs. 8 and 11.
- the pivot-rod 11 of the signal-setting arm is, however, located near the other end of the box from that at which the pivot-rod 6 of the arm 5 is located, the arms 5 and 10 being therefore adapted when raised to project angularly from the box in opposite directions and at different levels.
- a wire or cable connection 22 is provided between the lower end of the arm 18 and the lower end of an arm 25 in a similar box to that at which the motion originates, this connection being best illustrated in Fig. (i.
- the motion thus communicated to the arm of another box is transmitted, through said arm 25 and a lifting-lever 26, to elevate the signaling-arm 5 of the box to which such motion has been communicated, the arm 5 being thus held in a position to communicate a signal to a vehicle approaching the one by means of which said signaling-arm is raised.
- the levers 25 and 26 are arranged to slidingly engage each other along curved surfaces, whereby said levers may move in contact with each other and the lever 26 be lifted vertically when lever 25 is swung upon its horizontal pivot-pin 28.
- each of the boxes 2 is provided with a lever 30.
- This lever is pivoted at 31 and is provided with a rounded or angular face at its lower end 32, which when the lever is swung is adapted to impinge upon and depress the spring 33, thereby depressing the latch 20 and releasing arm 18, thus permitting the signal-setting arm 10 to return to its normal raised position.
- motion is com municated,through the corresponding arm 19, bellcrank lever 35, and a cable 36, to actuate a lever in another box located in the rear of the box from which the motion originates, this connection being also illustratedin Fig. 6.

- the signal-setting arm 10 of a box in the right-hand series is depressed, its motion will therefore be communicated, through the crossed pins 40 and 41, elbow-lever 42, cable 44, yoke-lever 45, and a vertically-extending lever 46, to raise lever 26, Fig. 10, and signal-conveying lever 5 to operative position.
- lever 46 is provided at its upper end with a curved contacting-surface adapted to move along and under a similarly-curved surface toward lever 26, whereby the swinging movement of levers 46 is effective to lift the lever 26 and arm 5.
- the springs 48 and 49 are used to retract levers 46 and 45, respectively, to normal position when such levers are released by their actuating connections.
- the signalconveying arm 5 in the left-hand series after being elevated as above described is held in raised position until the opposing box in the right-hand series receives motion from the advancing vehicle to release arm 18 from latch 20, whereupon the reaction of spring 48 retracts lever 46 to normal position, permits arm 5 to descend by gravity to normal position, and communicates a reverse movement, through the yoke-lever 45, cable 44, elbowlever 42, and pins 41 and 40,,to raise the signal-setting arm 10 of the opposing box in the right-hand series, thus restoring all the parts in both boxes to normal position.
- the signal-conveying arms raised in advance of a moving vehicle are those in the series at the right of such vehicle, while the signal-conveying arms raised in the rear of a moving vehicle are those at the left of such vehicle. It is therefore obvious that the raised ends of the arms 5,whether in advance or in the rear of the vehicle, will point toward such vehicle and will occupy positions for contacting with the contact-lever carried on the left-hand side of any other vehicle approaching from either the front or rear. Referring to Fig. 2, it will be observed that the vehicle is provided at 50 with such a lover, a roller 51 being mounted on the end of the lever in position for contacting with the arms 5 when raised from the part 3 of the box.
- the lever 50 is pivoted at 52 or any other convenient point on the vehicle and is connected by a wire 53 with any suitable form of signal, such as a whistle 54. It may also be connected with a throttle-lever 55 or with a brakelever 56, whereby the vehicle may be automatically stopped and an alarm sounded as soon as the roller 51 contacts with the raised sigupon a similar pin 41, extending at right ani naling-arm 5.
- the contacting arm 15 may be raised out of operative position by means of a lever 60, pivotally connected with the arm 15. The latter is simultaneously mounted in suitable guides 61 on the side of the vehicle.

BLOCK-SIGNAL SYSTEM FOR RAILWAYS.
SPECIFICATION forming part of Letters Patent No. 785,807, dated March 28, 1905.
Application filed August 17, 1904. Serial No. 221,011.
1'0 (.211 1117mm it may concern:
Be it known that I, Aueus'r Hons'rsormrua, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of W'isconsin, have invented new and useful Improvements in Block-Signal Systems for Railways, of which the following is a specification.
My invention relates to improvements in block-signal systems for railways.
The object of my invention is to provide simple and practical means for mechanically setting and resetting signals at the side of a railway-track from a vehicle moving along said track, each such vehicle being provided with auxiliary signaling mechanism adapted to be operated from the mechanism at the side of the track when the latter has been set in operative position by either a preceding or an approaching vehicle.
In the following description reference is had to the accompanying drawings, in which Figure 1 is a plan View of a railway-track equipped with my improved signaling apparatus. Fig. 2 is a cross-sectional view of a vehicle and track embodying my invention. Fig. 3 is a detail view illustrating the means for controlling the signal-setting mechanism of the vehicle. Fig. 4 is a view showing a portion of the road-bed and signal-boxes in longitudinal section, the track and a portion of a vehicle thereon being illustrated in elevation. Fig. 5 is a plan view of the connections between signal-boxes on opposite sides of the track, the track-rails being indicated. in dotted lines. Fig. 6 is a detail view showing a series of signal-boxes in vertical section illustrating the connections between the boxes in such series. Fig. 7 is a plan view showing a series of boxes on each side of a railway-track and provided with longitudinal and transverse connections. Fig. 8 is an enlarged vertical sectional view of a signal-box, showing the signal-setting mechanism in elevation. Fig. 9 is a horizontal sectional view of a single signal-box, drawn on line a of Fig. 8. Fig. 10 is a vertical sectional view of a signal-box, showing the signal-communicating mechanism. Fig. 11 is a sectional view of a signal-box, drawn on line 1 y of Figs. 8 and 10.
Like parts are identified by the same reference characters throughout the several views.
1 represents the rails of a railway-track, at each side of which a series of signaling-boxes 2 are located, as best shown in Figs. 1 and 7 Each of these signaling-boxes 2 is provided on the side farthest from the track with a raised extension 3, the part 4 of the box being materially lower than the part 3, as shown in Figs. 2 and 10. Each box is provided with a signal-conveying arm 5, pivoted at 6 near one end of the box and adapted to be lifted through a slot 7 in the top of part 3 to an angular position, as indicated by dotted lines in Fig. 10. A signal-setting arm is pivoted at 11 in the part a of the box and normally projects upwardly in an annular position through a slot 12 in the top of the box, Figs. 8 and 11. The pivot-rod 11 of the signal-setting arm is, however, located near the other end of the box from that at which the pivot-rod 6 of the arm 5 is located, the arms 5 and 10 being therefore adapted when raised to project angularly from the box in opposite directions and at different levels. An arm 15, connected with one side of the moving vehicle, is provided with a contact-roller 16, which is located in a position to engage and move along the inclined upper surface of the signal-setting arms 10 for the purpose of depressing said arms successively as the vehicle moves is depressed until the end of the lever swings past it, whereupon it reacts and abuts the inner face of the lever-surface as a stop to hold arm 10 in its depressed position.
A wire or cable connection 22 is provided between the lower end of the arm 18 and the lower end of an arm 25 in a similar box to that at which the motion originates, this connection being best illustrated in Fig. (i. The motion thus communicated to the arm of another box is transmitted, through said arm 25 and a lifting-lever 26, to elevate the signaling-arm 5 of the box to which such motion has been communicated, the arm 5 being thus held in a position to communicate a signal to a vehicle approaching the one by means of which said signaling-arm is raised. The levers 25 and 26 are arranged to slidingly engage each other along curved surfaces, whereby said levers may move in contact with each other and the lever 26 be lifted vertically when lever 25 is swung upon its horizontal pivot-pin 28.
Referring again to Fig. 8, it will be observed that each of the boxes 2 is provided with a lever 30. This lever is pivoted at 31 and is provided with a rounded or angular face at its lower end 32, which when the lever is swung is adapted to impinge upon and depress the spring 33, thereby depressing the latch 20 and releasing arm 18, thus permitting the signal-setting arm 10 to return to its normal raised position. When the arm 10 is depressed in any one of the boxes, motion is com municated,through the corresponding arm 19, bellcrank lever 35, and a cable 36, to actuate a lever in another box located in the rear of the box from which the motion originates, this connection being also illustratedin Fig. 6. 38 is a spring adapted to retract lever 30 to normal position. It will therefore be observed that by means of the signal-setting levers 10 in a series of boxes on one side of the track motion may be communicated, through the arms 18 and 19, respectively, to simultaneously cause the elevation of asignalconveyingarm 5 at a box in front of the moving vehicle and to also release and permit the readjustment of a signal-setting arm 10 at a box in the rear of the moving vehicle. The distant boxes so connected with the box from which the motion originates are in the construction shown the second boxes to the front and rear from the one being passed by the vehicle.
For convenience in description 1 shall hereinafter refer to the boxes from which the motion originates as those of the right-hand series, for it will be observed that in the construction illustrated the arm 15 is located at the right-hand side of the vehicle and is therefore in a position to contact only with the arms 10 of those boxes which are at the right-hand side of the track when viewed in the direction of vehicle movement. My invention, however, contemplates the provision of means for raising signaling-levers 5 in the boxes of the left-hand series simultaneously with the depression of the signal-setting levers 10 in the boxes of the right-hand series. To accomplish this result, 1 have provided each arm 10 with a laterally-projectingpin 40, which rests gles to the pin 40 from an elbow-lever 42, Fig. 11. The elbow-lever 42 is provided with a horizontal arm, pivoted at 43, and a downwardly-extending arm, connected at its lower end by a cable 44 with the yoke-lever 45 on the other side of the track and in the bottom of the opposing box of the left-hand series, Fig. 9. When the signal-setting arm 10 of a box in the right-hand series is depressed, its motion will therefore be communicated, through the crossed pins 40 and 41, elbow-lever 42, cable 44, yoke-lever 45, and a vertically-extending lever 46, to raise lever 26, Fig. 10, and signal-conveying lever 5 to operative position. It will be observed that the lever 46 is provided at its upper end with a curved contacting-surface adapted to move along and under a similarly-curved surface toward lever 26, whereby the swinging movement of levers 46 is effective to lift the lever 26 and arm 5. The springs 48 and 49 are used to retract levers 46 and 45, respectively, to normal position when such levers are released by their actuating connections. The signalconveying arm 5 in the left-hand series after being elevated as above described is held in raised position until the opposing box in the right-hand series receives motion from the advancing vehicle to release arm 18 from latch 20, whereupon the reaction of spring 48 retracts lever 46 to normal position, permits arm 5 to descend by gravity to normal position, and communicates a reverse movement, through the yoke-lever 45, cable 44, elbowlever 42, and pins 41 and 40,,to raise the signal-setting arm 10 of the opposing box in the right-hand series, thus restoring all the parts in both boxes to normal position.
From the foregoing description it will be understood that the signal-conveying arms raised in advance of a moving vehicle are those in the series at the right of such vehicle, while the signal-conveying arms raised in the rear of a moving vehicle are those at the left of such vehicle. It is therefore obvious that the raised ends of the arms 5,whether in advance or in the rear of the vehicle, will point toward such vehicle and will occupy positions for contacting with the contact-lever carried on the left-hand side of any other vehicle approaching from either the front or rear. Referring to Fig. 2, it will be observed that the vehicle is provided at 50 with such a lover, a roller 51 being mounted on the end of the lever in position for contacting with the arms 5 when raised from the part 3 of the box. The lever 50 is pivoted at 52 or any other convenient point on the vehicle and is connected by a wire 53 with any suitable form of signal, such as a whistle 54. It may also be connected with a throttle-lever 55 or with a brakelever 56, whereby the vehicle may be automatically stopped and an alarm sounded as soon as the roller 51 contacts with the raised sigupon a similar pin 41, extending at right ani naling-arm 5.
IIO
Vhen it is desired to back the vehicle or when for any purpose it is desired to move the vehicle without actuating the signal-setting arms 10, the contacting arm 15 may be raised out of operative position by means of a lever 60, pivotally connected with the arm 15. The latter is simultaneously mounted in suitable guides 61 on the side of the vehicle.
It will be understood that the various connecting parts will be suitably housed and protected from damage. For example, the connecting- cables 22 and 36 are inclosed in a tubular covering 64:. The cross-cables M are suitably inclosed by a tubular covering 65, Fig. 11.
