In carrying out my invention, I provide a central; station such as that indicated at C in Fig. 17, at which is disposed a switch, the

details of which are best seen in Figs. 1 and I 2. From this central station I may control the signals at. any number-of stations. In Fig. 171 haveshown six of such sub-stations, these being SflS and S respectively. v

f Referring now toFigs. 1 and 2, I have spaced relation by ,a cross member 3. ar-

ranged preferably at the four corners. J ourdesignated bvS, S S

naled inthe side plates 1 and 2 is a shaft 4 "which projects beyond thepplate 2 and upon which is a series of conducting circ u; lar disks (2', .03 ,03 (P, and d respectively, corresponding to the number of stations to be operated; .The disks are held in spaced relation by meansnof metal spacing disl as, 5; These disks d, (Z etc., are preferably made of copper or other conducting ,niaterial, and are'slottedor recessed on their 1. peripheries as shown at 1" in Fig. 5. The

disks (1, (Z3, etc., have recesses 1", 7, etc., disposed approximately 60" apart since in this particular instance, there are six stations.

On the shaft 4 is also a disk a made of The disks d, 03 etc., are designed to'be 'rotated by'the actuating train-shown in Figs. 1 and 2. From these figures it will be observed that a weight-W is attached to the end of a chain or cable 7 which passes over a reel 8 on a shaft 9. The shaft 9 bears- I a gear 10 which en ages a gear 11 on the shaft 41, thereby ten ing to rotate the disks when the shaft '4 is permitted to revolve.

' --The shaft 4 bears a gear 12 which engages '15 that inturn engages a pinion 16 on the shaft 17 carrying a stop or escapement wheel 18. It will readily be seen that the wheel 18 mustrevolve if the shaft ti-evolves, and .if the escapement wheel- 18 is stopped, the

' shaft'4 W111 be stopped likewise.

l The'means for stopping or releasing the escapement wheel 18 consists of a stop lever like that shown at 19 in Fig; This lever is provided. with a pivot shaft 20 journaled' in thefwalls l and 2, one end ofthe lever serving as an armature for the magnet .11, the opposite .end being bent laterally as shown at 1992 so'as to engage the teeth of the escapement wheel 18. .Alaterally extending -arm 19y projects above the disk e'but when the armature end of the lever 19 is deener gized, thelaterally, bent end'lQm tends to drop down into engagement with the teeth of-the escapement wheel 18, -see Fig. 4. It is prevented from engaging the teeth of the escapeinent wheel 18, however, by the engagementjof the laterally extending portion of the arm 19y with the top" of the insulate ing wheel -e' until the latter has been revolved far enough to bring one of. the slots 6, e ete. into alinement with the laterally projecting portion. of the arm 19y: whereupon the latter drops downwardly .and thus per- 1 mits theportion .1900 to enter between the teeth of the esea'pement wheel" 18, thus stopping-theactuating train. As long as the magnet Mv attracts the armatureen'd of the lever 19, the actuating mechanism is free to revolve under the action of theweight W,

as will be e plainedzlater.

Secured-toone of-the side walls such as that shown 'at-2 is a bracket 23 which bears a cylindrical rod 24on-which is pivotally and slidably mounted a cylindrical sleeve or bearing'p ortion 25 of alaterallycxtending conducting member or arm 26 having a handle 26w at its end.- The arm 26 is provided with an integral contact member 26y which is arranged to engage any one of a number of conducting pins or pegs extending upwardly from an extension of' the bracket 23, the extension being shown at 23m and the pins at 231 As will be seen Fig. 6,

in its periphery, as shown at 6", e 6, etc.,

the bracket 23 is suitably insulated from the plate 2. A companion bracket 23a is secured to theplate '1, .being insulated from it as clearly shown in'Figs. 1 and 2. The pivot rod 24- has one end secured to the bracket 23a. Theopposite end of the pivot rod. 24; is provided with acollar'27. The member 261 is provided with a groove 262 on itsbottom which is arranged to receive the edge of any of the disks'd, (2 etc, see Fig. '1, so as to let the arm 26 ride on the edge of the disk while the latter is revolving, thereby forming the revolution of the disk, as will be explain'ed' later. The sleeve 25, to" which the a gear ,13 on'a-stub shaft 1 1 bearing a gear z. e., the disk d: When the bearing sleeve 25 isin' contact with the collar 27 then the arm 26 will r'eston the outer disk at? whilethe side of the arm 26 will engage the peg or pm 231 When the arm 26 is riding on the edge of any of the intermediate disks, the side faces of the, arm will engage pegs on ;each side as shown 'in Fig. 6, thus making a goodlconnection between the arm and the bracket 23. The arm 26 may be swung upwardly by means of the handle 26m and can be'shifted laterally,'the sleeve 25. sliding on the rod 241, so as to bring the arm 26 and its contact I 261 into electrical connection with [any of the disks, which as stated before correspond to the diflerent stations. These sta 5, 6, as shown tions are numbered 1, 2 3, 4:, on the bracket 23% in F1g.;2.

Inorder to prevent the actuating train from running too fast, I provide a centrifu gal governor, the shaft 30 of which is journaled in'the side walls 1 and 2. Secured to the shaft is a pinion 31 which meshes with theescapement wheel. 18. The governor is also provided with arms 32 which are secured to the shaft, and. has a slidable sleeve 33 pi'votally connected by links 34 with the arms 32,said sleeve passing through a slotted arm 35 and being provided with a friction the machine is running too fast, the arms 32 will be spread apart thus drawing on. the sleeve 33 and bringing the friction 'disk up against the face of the arm 35. The latter is secured at one end to the plate 1, and is, in fact, a spring arm, so that the friction exerted between the disk 36 and the spring arm 35 will gradually. slow down theapparatus, or rather, it will prevent too rapid a motion.

1 disk 36,- see Fig. 1. It is, obvious that when .The apparatus" which is installed at the 7 various stations, as faras the actuating train and the means for stopping the same,

is concerned, .is practically identical with that at the central station. In the drawings I have indicated the parts whicha're similar to the parts at the central stat1on, by the same reference letters with the addition of the subscripts. The apparatus is best shown in Figs. 8 and 9. In these figures it will be observed that the insulating disk as is pro-- vided with the slots eta, (2 s, e 8, 6 8, etc. In Fig. 9, the arm 19ys is shown in the slot 6 8. The disk shown in the figure is arranged for the station S see'Fig. 17, and it will be observed that adjacent to the slot 6 8 there is a conducting member 40 which the arm 19ys'is adapted to engage iust before its entrance into the slot 638. The other stations have one conducting member like the member 40, adjacent one of thesix slots inthe wheel es.

For the station 1, its wheel es would have the conducting member 40 adjacent to the slot es; for the station S the; wheel would have the conducting segment adjacent to the slot 6 8, and so on as shown in Fig: 17.

At each substation a signal is arranged like that shownin Fig. 11. This consists of a semaphore arm 41 which is pivotally mounted at 42 upon a mast or upright 43.

The normal or clear position of the signal is vertical and it is held in this position by means of a catch 44 which is-pivoted'at 45 and is normally acted on by a sprin 46. The end of the catch on the opposite si e of the pivot has an armature 47 associated with amagnet48. When the armature 47 is attracted it will release the arm 41, thereby permitting it to swing down into the danger position shown in dotted lines in Fig. 1.

Associated with each substation is one or more of the trip mechanisms best shown in Fig. 12. This. consists of a casing 49 in which is mounted a plunger 50 pressed uponby a spring 51 and hearing at its top a horizontally disposed impact member 52, curved at both ends. Normally the plunger 50 is held by means of a sprlngpressed catch or brake valve'operating lever 61, see Fig. 15.

In Fig. 17 I have shown diagrammatically the circuit connection between the central" station C and the stations "S, S, S etc.

The operation of this signaling and train stopping mechanism'will best be understood by taking a specific, example.

Let us assume that the operator at the-central station C wishes to signal a certain train the station S It consists of a catch 57 to stop at station S and also wishes to set a trip so that if'the engineer does not obey'a signal, the train will be stopped in spite of his actions. The operator at the central sta- .tion C lifts the handle 260a and slides the latter longitudinally of the rod 24 until the arm 26 is over the disk d corresponding to He then lowers'the handle so that the contact26y engages the edge of the-disk 01?. .As long as the contact 26y is engaging the disk 03*, currentwill flow from the battery B, see Fig. 17 throughthe main line wire L, from ground through the magnet-M, shaft 4, disk (5 26, and back to battery. It will be noted-that the magnetsM, MS, M 8, etc., all act simultaneously. The actuating mechanism at each station begins to revolve its disk 6, while the actuating mechanism at the central station begins .to

revolve the six disks d, (P, etc.-, as well as the disk'c. The apparatus at the central station ,and at the substations continues to revolve until the slot or groove r of the disk (5 comes into registration with the contact 26y, whereupon the current will be broken at this point. This, it will be observed from Fig. 17, is just before theend 19y of the lever 19 reaches the slot or recess 6 of the disk 6. A slight further rotation will. permit the arm to enter the slot and thus per- 9b mit the laterally bent end 1950 of the; lever to engage the. escapement wheel 18'of'the central station. thus stopping the actuating mechamsm.

, When the'disk e of the substation starts to revolve by the simultaneous action of the control magnets, MS, M S, M S,-etc., they revolve synchronously owing to the action 01 the governor. When the current is cut oli from the main line L by. the registration of the slot or recess 1' of disk (Z with the contact 26y, see Fig. 17, then the levers 19s,

198 etc., will drop downwardly simul taneously. The cutting ofi" of the current is timed so that the lever drops down just after the slot in the disk e atthe station at which the signal isto be shown, which :is immediately in frontv of, or which; precedes the slotin which it is. desired that the end of the lever shall rest,- has passed -vthe' end of the lever. Consider Fig. 17 Theen'd of the lever19s drops downwardly justafter the recess 6 8 has passed theend of the'lever with the disk e rotating in the direction shown by the arrow. The end of the lever 198 will therefore rest on the surface-of the 7 disk 6. The ends ofthe other levers correspondingto 19s at the various stations, will rest on their respective disks. Further rotation of the disk 6 at the various stations willbring the end of the lever 195 into an instant prior to its registration with the engagement with the contact 40 at station 8 recess 6 8. This condition is shown in Fig.

17 at station S It will observed that the levers corresponding to the lever 19:; at the other stations, are none of them in engagement with the contacts at the peripheries of .the disks 6, since, as stated before, these contacts are placed adjacent to the particular recess at which it is desired to stop the 'rotationof the disk. With the end of the lever 19 engaging the contact 40, a

' circuit will be established from the local battery B, through these contacts and through the release magnet 54:8 which will release the catch to permit the trip 528 to be. projected into the path of the spring conmechanism, and also of the brake valve lever releasing mechanism. This will cause the i steam to be shut off and the brakes'to be. set, thereby causing the stopping of, the

train.

At the same time the magnet 488 will cause the operationof the trip 4:4:8 to release the semaphore 418 so as to bring it to danger position shown in Fig. l7.v

It will be observed that the local circuit through the battery B is closed only for an instant, so that when it is desired to reset the semaphore, it may be done by pulling downwardly, on a cord or other suitable member I v,

tro-magnet acting on the opposite end of the such as that shownat 7 O in Fig. 17 at station S The trip may also be reset by pushing downwardly onit until it comes into engagement with the catch. i

I have explained how the signal and trip at one of the stations may be operated, but

it is obviousthatthe others are operated in the same manner. The "recesses such as that. shown at r in the disk 0Z whichcause the cutting ofl-of the current, as already explained, are arranged in definite relation with respect to the recesses 6'8, 6 8, e s, ,etc.,

so that all the operator at the central station has to do, is to place theconducting arm upon the proper disk at the central station as described, whereupon the apparatus will start 'up and the signal and trip will be thrown.

It will be seen from the description given that the apparatus is positive in action and j requires only slight efi'ort on the'part of the central station operator to correctly manip- .ulate the device. I amawarethat other forms of the device based upon the same general plan, might bemade without departing from the spirit of thsinvention.
