In carrying'out my invention theroad is equipped Withione or more devices 35 i' or indicating land-slides and the like, Which devices comprise a a'ir of posts 36, to one of which a rope or cab e 37 is secured, and the cable -37 passes through the ot-her post 36 and engages a spring-arm 33, carried by said latter post 36, which 'spring-arm is drawn toward the post 36 should fallen rock or earth engage the cable 37 and -move the same out of aline- Tov enable the circuit to'be made through the latch 33, Which is in electrical connection through a Wire 41 withl the lrespective block-section of the rail 2 that controls the land-slide d evice,I provide a second latch member 39, having va latch portion 39a for cooperating with the latchportion 38l of the latch 38, so that VWhen thecable 37 moves'the latch portion 33a toward4 the post 36 it Will' move under the latch member 39 and become locked in such position, thus closing the electrical circuit from. the latch '38 to the latch member 39, which latch member 39 is in electrical contact through a Wire 40 with the rail 1.

In order to indicate Washou-ts along the line, I provide the-ties 8 at suitable intervals with-a pair of contact members 3, electrically connected together by a Wire that is I' drawn taut between them and to which the Wire 53 is attached.

The magnet 65 of annunciator mechanism 1 is in circuit with the Contact 66a of the engine-carried contact-maker A, that coperates with the. contact 5011 of the stationary contact member B, 'which contact 50a is in connection with the block-section of the rail l-through thewire' 50, as'before specified. Thus the land-slide mechanism 35, a car or engine in the iirst block ahead, and the rail- .spreading mechanism all cooperate with itiie annunciato:rv mechanism No. 1.
The washout 8 and the bridge mechanism v 11 are in circuit through the wire 53, contact 453a of contact-maker B, and contact `63a of contact A through the wire 63 with magnet of annunciator mechanism No. 4. Thus the signals lroin the washouts-indicator mechanism 8 and thebridge mechanism 11v will be registered on annunciator mechanism No. 4, while the wires 15 15 and station v16 are adapted to be in circuit with an indicator-magnet oi the annunciator mechanism No. 3 by reason ofthe nected tothe wire 52a, more full)- hereinafter.

The magnet 65 ot annunciator mechanism No. 2 is also connected with the wire 61, that cooperates with contact 61a of the contact-maker A and with the contact 53a of the contact-maker B.
it should be stated that the station 16 and the telegraph apparatus 19 and 1S are in cir- 'cuit with the amiunciator mechanism No. by reason of the with the wire 52, -asuitable telegraph instrument 100 being placed in circuit with the magnet' 65 of the annunciator mechanism-No. 3

The anni-meiator mechanism No. 5 has a signal-light S5* in circuit with its magnet 65, and the said magnet 65 also connects'with the wire 64, that coperates with the contact 6-1a of the maker A, which contact 641a in turn cooperates with the contact 54, that is in electrical connection with the block ahead ot that with which the wire 50 connects, such connection being made through a wire 54, as shown.

When the magnet 7 04 is energized, the armature "l thereof will be drawn down, thus causing the valve 70d in the lateral 72 l ot the air-pipe'73 to be opened, thus permitting'air to passiromthe pipe 73 to the lateral 72 into the cylinder 7 4 and forcing the piston 7.3 into the direction of the arrow, a vent 74a being provided to permit exhaust oi" the air within the cylinder.

inasrnuchas by this time the engine will have moved its contact member A out of engagement with the contact member B (the engine running when the Contact members A and B engage one another momentarily) the circuit is broken at the contacts 60:t and 50a. Therefore the signal-lamp S5 would become extinguished were it'not for the fact that the contact members 67 and 68 are immediately brought into engagementzwhen the drop 66 falls, so as to make the circuitirom positivey pole of dynamo 86 through lamp 85, wire 8521, wire 60h, magnet 65 of annunciator No. l, across contacts 67 68, through wire 69, to magnet 70, and from magnet 7G. through wire 7l, back to the negative pole of dynamo,

The same cycle of operations occur should the switch 25a be open or a train be 752 on the siding with the rear car projecting 'too near to the main line.
