Sixth, to gravity in one direction, and an applied source of-enprovide a train control or stop device carried by a car ergy, asan electric motor, in the reverse direction, for or train and adapted to control either the mnree oi setting them so as to indicate the condition of the blue}. power thereof, or the brakee, in both. and to combine sections, or other features of warning to which they retherewith a power impelled semaphore no etmutructed late, and in such mannerthat when released the conand arranged that when tln m-maphore stands in a stantly acting force will let them to indicate a definite definite position the train mopping device will not be actuated and when it stands in either of two other poeitions said train stopping device will always be octttated. Seventh, to pm iden rd p device beeidc the roadway for automatically eff etim the m-ppage of a train when abnormal track I'fllldlllullrt occur. or when the controlling force which effects the rob-.ue of each stop device is intermpted or disturbed, said -atop device being 'of a double or duplex nature and :40 conetructed and arranged that (a) when the main track in clear it in out oi operative relation; (6) when he side track is in alinement for side tracking a train it is in operative relation for stoppimr the train; (r) when llle mntrolling aource of energy fails it is also in operative relation for stopping a train. all tmim or cam [now int: over the route being provided with automatic train controlling apparatus adapted to Inaetuatcd by said atop device.

in prior applications tor patents tiled by miin the U. 8. Patent Ullice l have discl sed railway signals in the nature of semaphores operated by electric motors in one direction only acaiusta constantly acting; force, as gravity, and controlled by the application of electrical energy. and l have drown, described and claimed train stopping devices carried by a car or train adapted to dintxnmeet the wart-e of power and to apply the brakes through the l\j 't'llt' of the m-maphoren them aelve when released or act. in definite positions, as danger.

In all of the beforc-nn-ntiomnl applient iota. however, the semaphores have been rotated always in the same Patented Nov. 6, 1907. 1907- Iflt 3 52.?-

It also relates to safety appliances for automatically effecting the stoppage of a car or train in the event of danger thereto, due either to an abnormal track condition onto the failure of the controlling devices of either the signals or the stop devices, and to theme ends it has for its objects, first. to provide means for letting a signal in any one of two or more definite plllllltllltl so as to indicate one or more conditions by causing the controlling force to be applied in reverse directions and in ouch manner that when the signal is left not in either of the aforesaid poaitions the conetantly acting force, a gravity, tend: always to move it to a definite position indicating danger. Second, to combine such a signal with a main track, a ride track and a rail switch and in ouch manner that when the nwiteh is in one position and the signal held against the iorce of gravity it in exported to view pointing in one direction and against the constantly acting force, an gravity. and when the switch is moved in a reve direction-the signal in likewiae moved by the applied force into a diametrically opposite partition and held as before against the constantiy acting force, an gravity. the signal giving three indications; (l) main track rails in. alinemont; (2) aide track rails in alinement; (8) dangenthe arrangement being each that always when the constantly acting force of gravity is permit ted to act to move the nignal it goeajo a definite p'oeilion. an danger. Third. to provide mutual for eontmlling the mwemont of a signal, as a nelnaphore, through the l agency oi a eingle electric motor adapted to move the l direction and set or locked against the force of gravity. same in either direction agaiunt the force of gravity i said nculaphorcn being capable of indimning two ot and to lock it when no moved to the limit in either dil time: only; namely, safety, or danger: or-safety or enureetion with the motor out of circuit, combining tlteretion. where dintaut signals are list-ti. with meann for interrupting the motor circuit should The present invention contemplate the application the locking meann fail to act. Fourth. to combine 5 of rotary electric melon lotlto movement f N'llllillilllrt} with a main track a side track i aicuais in different direetiomand in melt manner a track rails thereof, a switch nignal operab-d by an electo give ditlereutiudi\'idtlul llttlh'nlitmr Many len\'- tric motor nnd provided with meana whereby when ing the nellntplture or signal when at or looked tuna-r the switch-rails are moved in oppmdte directions the the influence of a constantly aetine l tu'rt', as gr;|\|'t rotary armature of the operating motor of tho signal and 1 effect this novel result through the agency oi l till changing means whereby when it is desired to have the signal set in either clue of two definite positions the armature of the motor is caused to rotate in the proper direction by causing the controlling current to flow in such direction thercthrough as to effect the result, the arrangement being such that when the semaphore has reached its indicating position it is locked with the motor cut out of circuit.

The present invention also contemplates the use of a double or duplex stop device operated and controlled by two sources of energy, as gravity and electricity, and adapted for use particularly in connection with side tracks'in railway systems, said stop device being so constructed that (a) when the main track rails are in alinemeut it is normally held out oi operative relation with a train controlling device carried by a car or train; (b) when the main track rails are in alinement with the side track rails it is in operative relation with the train controlling device carried by the car or train; (0) when the controlling source of energy fails or is interrupted it is also in operative relation with the train control device carried by the car or train. v

. For a full and clear understanding of my invention, such as will enable others skilled in the art to construct and use the same, reference is bad to the accompanying drawings, in which,

Figure 1 is a diagrammatic view illustrating an electric motor having its armature operatively connected to a. semaphore or signal and to the operating circuit of a dynamo electric machine; a pair oi main track rails, a pair of side track rails, a rail switch and a pole changer connected thereto for varying the direction of the cur-r rent flow to the armature oi the motor when the switch is closed being also shown, the signal being shown as locked in a dcliuitc position through the agency of a locking device controlled by a source of electrical energy wholly indcpemlont of and disconnected from the main source of current supply which drives the motor.

Fig. 2 is a transverse section taken through the roadbed oi a railway and the signal box inclosing one of my novel signals, a car being shown in cud view and train controlling devices carried thereby, the signal box being supported by a semaphore post beside the track.-

ltelorring now to the drawings in detail, and first to Fig. l, l, I, l, I represent the mils oi the main track,

2, 2, thcmils of a side track, and 3, 3, a pair of'switeh rails shown in alincmcnt with the main track rails and connected by a switch rod 4 with a switch-lover 5 pivoted at (i and prot idod with an operating handle 7,said parts I and .i constituting mcuus for moving the switch rails 3, 2i, and tcrmcd by Inc throughout the spmzilicution and the claims a rail-swit'ch. 8 is tho movable port of a pole changing dcvice cnrricd by thc switch- ]mwr 5, and it, In on! movulglo contact plates carridd at thc other cud of thc switch lever B, the plate IO-beiuginsnlatcd from said lovci. ll, l2, ll IBnrostatiouary contacts locutcd on opposite sides of said movablecontact plates.

'26 is a locking electromagnet included in a circuit 27 with a local battery 28 or other source of electrical energy wholly independent of or disconnected from the main source of energy which operates the motor.

The semaphore arm 18 and the stop arm 19 together with their supporting shaft constitute a double or'duplex stop device operated by a single electromotive devim and controlled by a single electro-magnetic locking device, and the structural arrangement is such that with a single olectromotivo device and a single locking device I am enabled to automatically effect the stoppage of a train for three abnormalconditions, two of the same being track conditions and the third a failure of the source of energy which locks or holds the stop device at safety.

D is a dynamo electric machine or main source of electrical energy for operating the motor 17 and m, m, are current mains connected thereto; 10, in, being branch conductors running from the current mains to the stationary contacts 11, 11, 15, and .m, m a shunt 96 circuit connecting the field magnet coils of the motor 17 directly in circuit with the current mains m,.m.

Referring now to Fig. 2, 0 represents a car the wheels 0! 'which are standing upon tltetraclr rails 1, 1. 's, I, represent the operating arms of two train controlling 100 devices located on opposite sides of the car. the nme being substantially like similar devices in a prior application flied by me in the U. 8. Patent Ofiice on the 9th day of May, 1906, Serial No. 260,625, and

adapted to control the applicationof power and oi the 106 brakes whenths car is traveling in either direction. 8 represents a; semaphore post beside the track and A a semaphore box completely protecting the operative parts of the apparatua-disclmxl in Fig. l-and shown therein as incioaod in brolten lines.-

it, ll. represent two red colored glass lenses and W a white glass lens all carritsl by the name disk which supports the stunapltoro ill, the two lenses it, it being 90 apart and tho lonsWtlO' irorn one of the lmiorc-nrentioned lenses and 160,imm the other, the lamp being shown inti'ris figure of thc drawings behind the white lcus W, and the mnnaphore 18 in full lincs at sal'oty indicating a main traclr'crmnoctibn; and in dotted lines indicating a side track connection.

'Supposo tho car (i to be traveling in the diagrumnnttic view Fig. i from right to loft and the truck rail and circuit relations as therein disclosed; that is to say, with thc switch rails 3, 3,-in alinoun-nt with-the main track rails l, 1.- Und'or this mnditiorroi aiiuirs current flows from the positive polo of tho dymuno clcctric untcbinc l) by tho plus currcnt main in to and through the fluid rnugnot coils of the motor 17 by shunt circuit m to the negative current main or, and a branch thorooi tends to llow through the current rnuiu 1n, branch conductor w, .uppcr stationary contact 1'], movable I30 contact plate 9, switch lever b, movable part it of the pole changer, pole changing contact spring l3, con' tlucior 16, through the armature of the motor 17, arniatnre lever 20and movable contact plate ll at the free being locked in the position shown in both figures of the drawings against the force of gravity due to its own weight by a detent on the armature of the lever 20, extending into one of the two locking notches as shown; consequently, indication is given to the motorman on the car C, Fig. 2, by reason of the semaphore l5 extending transverse the track and in a direction toward the same, that the switch rails 3, 8, are in alincmcnt with the main track rails 1, 1 and he may proceed. At night the rays from the lamp through the white lens W will give alike indication. Should the switch lever b be thrown in a reverse direction the first effect is to break the main circuit of the generator D between the movable contact plate 9 and upper stationary -cont act ll and the local circuit 27 of the battery 28 between the movable contact plate 10 and upper stationary contact plate 12, so that the magnet 20 is demagnctized and the armature lever 20 released; consequently, the semaphore 18 falls immediately by its own weight into a vertical position indicating danger and at the same time the movable contact plate 2i closes the motor circuit through the conductor 16 and stationary conta t plate 22. As the switch handle 7 is carried forward the movable part 8 of t'he pole changing device comes into contact with the pole changing contact spring 14 and lifts it out of contact with the stationary contact 15, the main circuit from the gcnerator D, through tlmarmature of the motor, anththe local circuit from the battery 28 remaining open until aftcrthe spring 14 has been lifted out of contact with the stationary contact 15. Further movement brings the free end of the contact spring 13 into contact with the contact plate 15 and the movable contact plates 9 and 10 into contact with their respective lower contacts 11 and 12. \\'hen this occurs the switch rails 3 have been thrown to their limit and the main track rails l, l, are now in alinement with the side track rails 2, 2. for side tracking an incoming train. Current now flows from the generator U by the plus current main in, bntnch conductor no, lower contact plate 1], movable contact plate ll, switch lev r 5. movable part Sol the pole changing device; movable contact spring 14. (OlldllCtOl ltl, switches 23-24, stationary contact 22,.movable contact. plate 2l ultllnltlte lever 20, through the armature coils of the motor; eonductor 10, by way of contact spring 13, stationary contact l5 and conductor to, to the other current main and negative pole of the generator I). Gonsequently, the motor running in a reverse direction rotates the semaph'ire 18 into the position shown in dotted lines Fig. 2. At the same time that the working current was closed between the movable contact plate 9 and stationary contact l1 the circuit- 27 from the battery 28 and through the electromagnet go was closed between the movable contact plate 10 and lower stationary contact plate 12, so that-tho armature lever 20 was drawn forward; but the dett at on the free end of said lever at this time rests upon the cylindrical surface of a disk which is provided with the two locking notches, as shown; so that the motor circuit cannot be interruptml until locking armature lever 20 is drawn forward and the dctent falls into the notch locking the signal in the position shown in dotted lines Fig. 2 and interrupting the I motor circuit between the movable and stationary conend thereof, where it is interrupted, the semaphore tact plates 21 and 22.

The stop arm or device 19 has now been rotated through Ht)" fro..; the position shown in full lilies. Fig. 2, and into the position shown in dotted lines so that it. is in the path of the operating arm I of the train controlling device carried by the car and shou.d the train proceed it will be automatically stopped. For like reason should the battery 28 fail, or the circuit thereof be interrupted at'any time when the signal is locked in either of the two positions hercinheforo described, th weight of the semaphore 18 will cause it to drop into a vertical position in the path of the aforesaid arm, thus giving indication of the fact that th semaphore is out of order and stopping the train. Winn the semaphore is in the position shown in full lines the white lens W is in front of the lamp and gives an indication of safety. When said semaphore is in a vertical position the upper red lens R is in 'front of the lamp giving indication of danger and when in the position shown in dotted lines the second red lens It has been rotated through 180 giving an indication of danger; or, if preferred, this lens may be green giving a special indication of the fact that the switch rails 3, 3 are set for the siding.

Should the battery 28 fail or should the circuit thereof be interrupted in any manner the motor circuit will, of Ctltll'sc, be immediately closed, no matter in which position the switch level 5 may be thrown, so that it becomes necessary to provide means for preventing the motor from rotating the signal continuously, as would be the case should the contact plate 21 beallowed to remain permanently in contact with the stationary contact. plate 22. To avoid a possibility of such an occurrence two rotary switches 23, 24 are located in series relation in the branch conductor 16 and in the path of the pin 25, so that should the motor circuit be left closed for any reason, as indicated, no matter in which direction ahe semaphore may be moved the pin 25 will interrupt the circuit and, consequently, the semaphore will drop by its own weight to danger. Two switches 23, and 24 are preferably used and located as shown for as uring the fact that when the pin 25 strikes either one or the other, dependent upon the direction of relation, there 'will be sutlicient weight at the end oihc semaphore, owing to its angular position at that time, to assure its dropping to a position of danger. In other words, if only one switch were used it would lie accessory to locate it at a central position corresponding to the indicated position of the stop-arm or device It: and it might possibly occur that the soma- .phore would stop on dead center, the arrangement details of construction disclosed in the accompanying drawing, hereinbefore described and hereinafter claimed, as a nmnber of the features thereof might be departed from and still come within the scope of my claims. To illustrate, although 1 have shown the this disk is rotated through 180 at which time the 1 novel semaphore and semaphorwoperating and conat eeomo trolling mechaniom 'u applicable a awitch, a main track, nnd aide track rails, many oi the features tlton-oi may be utllinod in connection with ntilwny eiunoln generally, one oi the entonti tl points oi novelty oi my invention being the it-atnro oi controlling it m-lnophtmor equivalent signal by n iionrco oi applioti power, as a rotary eloctric'nmtor, which oppoeen n constantly acting iorco, an gravity, in melt manner no to ponnlt oi the netting oi the nlgnnl in tlil'icrt-nt poeitimtn nntl maintainint: tho nine incited or hold in mid tlitlorent poeitionn ngninut tho iorco oi gravity with the motor nttt oi eircuit, no that when reletnlcd it will always M nnie n doiinito partition indicntivo oi n riotinito ooittlilimt, ea danger.
