Applcationled November 2, 1915. Serial No, 59,320.

To all 207mm it may concerm,

I Be it known that I, FREDERICK W. COLE, acitizen of the United States, residing at NewtoniHighlands, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Successive Non- 'Interference Signal-Boxes, of Which'the following is a specification.

This invention relates to fire-alarm tele.- grapli signal-boxes, and particularly to that type commonly known as successive non-in- The Ordinary box ot this type, when pulled, is arranged to send'.

terference signal-boxeswill be delayed fora short or a long perio of time depending upon the conditions which caused the delay. There comes -a time after a boxhas been pulled that the transmission of its signal is absolutely use-` less, its reception being too late for the call of the tire apparatus, and in fact it had much better not then be sent for the reason that it might cause delay in responding to some The particular broad characteristic feature of the box embodying this invention is its capability of lsendingits signal promptly, when the box is pulled, and if for any reason its signal is delayed, then for sending it promptly upon' the cessationfof the conditions Which caused its delay but only Within a reasonable length of time, and restoring the component parts to normal as soon as it has sent its signal or at the expiration of the 'period of time which is allotted for the sending. of the signal.

-While my invention is of abroad characf ter, and I do not wish to limit it to any particular structure, yet herein the abnormal extension of time Within Which the signal may be properly sentis acquired by delaying the action of thestopping-means for the sig-A naling-train, in case another signal is being sent over the line, or there'is trouble on the line,'whereuponthe signaling-train is permitted` to continue` its operation, but cannot send its signal, such delay beingfor a. period of time which vvaries according to the conditions existing which caused the delay, but-in no event will it be longer than a predetermined period of amawhieh is auoaea during which a signal may besent, and at the expiration of which 'period of time the stopping-means will operate to stop the train in any event andthe component parts of the .box Will then be restored .to normal preparatory to being again pulled. The'delaying-means for the ystopping-means. by which the train is permitted to continue running,

` but only for a predetermined period of time,

may consist of means for disconnecting the stopping-means from thel 'signaling-train,v

which is operable to thereafter connect ythe same thereivithzvthereby to delaythe'stopping of the'train, and subsequently to con-A 4nect the same with the train, after Which it will operateto stopv the train When the train has run llong enough to send the predeter-l mined number of rounds which itis designed tosend.` I Disconnection from the signaling-train may be controlled by the armature of the non-interference magnet, which is'the elementresponsive tol anothersignal being sentfrom another box or Ato trouble on the lineT and the subsequent connection of the stopping-means 'With lthe train consists of means adapted to be' opel#` ated or controlled by the train in running. Connection of the stopping-means With the train, after it has been disconnected thereof the stopping-means.

from, Will be attempted repeatedly at reguy lar times, as for instance,l at the end of each v round of the signal during the time allotted for the boxto run, and such attempts Will be .controlled.by the train in running, and `When lmade Will operate tostop the train after a predetermined number of roundsof the signal have been correctly transmitted or the train hasrun for a corresponding period of time.v 4

` Of course, it Will be understood that yin v case there'is no other signal being sent over 'the line or there is no trouble on the line the stoppingfmeans will not be' disconnected from the train and will operate to stop the train When the, predetermined number of will many times result in vdelaying the send-r i ing of the delayed signal only for al short period of'time, which is a great advantage,4

is herein controlled by aV counting-device adapted to be operated by the train in running, being moved at the end of each round of the'Y signal, and when a predetermined number of rounds have been counted od', so to speak, it operatesto prevent the armature from further controlling the connection of the stopping-means with the signaling-train, which means is then driven by the train, in regular manner, for a predetermined number of rounds whereupon it operates to stop the train Whether the delayed signal is sent or not. The counting-device is adapted to be returned to itsnormal position by a spring and is released to do so by the stoppingmeans', thus providing for the return to normal of the counting-device Whenever the train is stopped. |Thus in accordance With this invention,` as illustrated in the embodi-lv ment here shoivn,the disconnecting means for the stopping-means is controlled bythe non-interference magnet to disconnect Said stopping-means from the signaling-train; and connection of the stoppingmeans, with the signaling-train, after it has been disconnected therefrom, is attempted at the end of each round of the signal by.means cotrolled bythe train inv running, and connection of the Vstoppiiig-means with the signaling-train after vit has been disconnected therefrom -is maintained in any event at the 'end of a predetermined' number of rounds of the signal by the counting-device which is adapted to be'operated by the signaling.-` train in running to maintain 'sucliconnec.

tion, and isl adapted to be released by the stopping-means `When acting to stop the' f train toreturn tonormal.

Figure l is a front elevation cfasucces-` sive non-interference signal-box embodying this invention, its component parts being in their normal position of rest.` Fig. 2 is a similar view1 many of the parts being omitted to exposel those in rear of them.

Fig. 3 is a side elevation of the signalboX shown in Fig. vl.

Fig. 4 is a vertical, sectional detail of a portion of the boX.

F igs. 5 to 9 are fragmentary details of certain associated parts in the different positions they-Will occupy during the ruiming of the train and under different conditionsmounted to rotate on the stud 3.' A stopi member is secured to said pinion or other- Wisearranged'to rotate with it, which member is here shown as a disk 6 having a projection 7. A pin '8 projects iaterally from the'faoef ofthe toothed-gear a, .and,-as said Winding-shaft rotates, passes through an orbit, and 'the projection 7 is arranged to enter the orbital path of said pin upon each 4revolution of the pinion, and is4 adapted to be engagedby'said pin to limit the Winding-motion of the shaft when the spring has been'tvound, thusto obviate Winding the spring overtight. The relative number of teeth on the toothed-gear i and pinion are su'ch as to permit the toothedgear to make several rotations before its pin encounters the projection 7, notwithstanding said yprojection passes through the' orbital path of the pin during each of these rotations.` The shaft is Wound by turning it counter-clockwise and is rotated by the main spring in a clockwise direction. There is also' mounted on the .Windingsliaft a spur-gear l0, whichl is adapted to be driven by the shaft, being connected therewith in any usual manner, as by a pawl 12, arranged on the gear 10, which engages a ratchet-Wheel 13 secured to the shaft, so that the energy of the spring may beimparted to said gear. Said gear 10 en- Sts gages a pinion 14, see Fig. a and dotted lines y Fig. 2, securedto a shaft `l,to' which the box-number signal-Wheel .16 ,is'rsecured A spur-gear 20` is secured to or arrangedto rotate with the sigi'ial-ivlieel shaft, it being,

here shown as mounted upon and securedk tothe hub of the pinion it, and said gear 2O engagesa pinion 21, secured to a shaft 22, to which the escapement-Wheel-23 is secured, said wheel 23 being engaged by a pallet 24, secured'toa pallet-shaft 25, bearing a" fan E26. Stripped'of*associated elements, to be hereinafterdcribed, 4thisytrain of gearing Y serves asrand constitutes the signaling-train. This signaling-train is adapted to be held vat rest against the energy of its actuating` spring by stopping-means adapted to be v"controlled, by the box-pull to start the train,

and to be operated by the train injrunning to stop thetrain. pingmeans is adapted to be disconnected from the train, to permit the train to run independently thereof, in case the signal is delayed. The stopping-means here shown consists of a dislr 36, having a single notch 37, which receives the end-portion or tooth 38 of a locking lever 39, which is secured to a pivot-shaft 40, said notched disk, which serves as the stop-Wheel, being loosely mounted, for convenience, on the .Windingshaft l. Said'notched disk is .arranged to be driven by the Signalingftrain by means whereby it will make one rotation to-sev eral rotations, say four, of the signal-Wheel, L30 I Furthermore, the stopso Vthat in the normal running of the train,

several rounds of the signal, say foun -is engaged by a pinion 34, arranged for con# venience on the signalfwheel shaft 15, and

n yadapted for connection with the train.

Said pinion 34 is loosely supported on said shaft 15, and ,on its hub a disk is rigidly secured, having pivoted on its face,`

aty 32, a dog 31, one end of which has an engaging4portion arranged to engageand disengage a pin 50, which projects laterally from one of the train-wheels,` as 20, and the other end offwhichforms an vektensionor tail 72, which may extend outward beyond the edge ofthe disk, see Fig. 2, or may be otherwise arranged for engagement with means to cause it to be moved von its pivot. By4 means of the pin 30'and dog 31,' thel stopping-means` is adapted to be connected 'with and disconnected from the train.

When the dog is in engagement with the pin, the stopping-means isconnected with stop-wheel 36, and the dog 31l engages the pin 30, the signaling-train is held at rest through the gear 35, pinion 34, disk 33, dog

V31, pin 30, and train-wheel 20; and when said locking-lever disengages said notch the signaling-trainv is permitted to run; and

when the dog 31 isomoved out of the path of movement. of the pin 30, the signalingtrain' is permitted to run and the stopping-` `means, including the stop-wheel, is permitted to remain at rest.

The box-pull 41,.shown as a pivoted lever, is arranged beneath the locking-member 39, by which said kmember may be lifted against the tension of its return-spring 12,

to disengage the notched disk 36, and there-l by release the signaling-train.

The signal-key 45 is arranged to control the make and breakof a pair of Contact: pens 46, 117 by cooperating with the signal-` wlieel 16, it having a projection 51, arranged for engagement with the" toothed edge-portion of the signal-wheel for the ac complishment of thisresult. It is pivoted at 48, and its movements to and'i fro are limited by va pin '49, which is extended laterally from it and' enters a hole 50 in the frame, which hole"r is madelarger than the pin. It also has a pin 52, arranged for engagement with a prop 53,. by which itis held in 'its .closed circuit position, but which, when said prop ris lifted, will pass beneathy the prop, so as to act to hold the prop in elevated position While said key is in its open position. The upper end-portion of the key vis arranged for cooperation with a pin 54, on the box-controller, in such manner that each can at times control the other,` as will be observed. Itslower end-` portion has an extension 55 which is a-rranged to-be engaged by a pin 56 onthe' locking-member 89, byv which it is restoredV -to normal or closed position when the locking-member enters the not'ch of the stopwheel.

'The

prop

5,3 is piyoted at one end, asat' `times by the prop, or the prop by the key.

The projectionY 61 isadapted for engagementwi a cam 63, which is arranged on' or rotatable with the signal-wheel. Thisl cam extends entirely around or is oo-eXtensive with the signal-wheel 'and might be made as a flangeon the wheel; and a portion thereof, which corresponds with the period between the end of one round and the beginning of the nekt round rof the signal, is cut away, or ,in lieu thereof a void may be provided. Along the cut-away por-l tion' of the cam the vprop is permittedat times to `move into its lowermost position, see Fig.` l, in which position its projection 6.0, engages or passes beneath the pin 52 on the signal-key to act thereafter to hold or prop said key with its contact-pens in closed position. l

The remaining portion yof the cam acts to lift and hold the prop high enough for its projection` 60 to move into a plane above Vthefpin .52, see Fig. 5, so as to admit of said V,pin passing beneath it. @When the prop is thus lifted by the cam, thesignal-key is free to moveA into thefinterdentalvspaces of thefsignal-wheel, unless otherwise held, and when so moved, see Fig. 6, its 'pin 52 will lpass beneath the projection 60 on the prop,

and will act to hold said prop in elevated position, .so as to prevent it from again falling into its cut-away portion,v i

When' the box is at rest, the projection 61 on the prop will be' disposed intermediate the length of the cut-away portion of the cam, andthe prop will then be in its lowerytemporarily be held from' opening while the notch inthe cam is passing and the signal-wheel will rotate and when its rst tooth .reachesthe key the cam will soon litt the prop into the position shown in Fig.`5,

thereby disengaging the signal-key, andthe 'reason that the prop is held in eleva-ted position bythe cam, during the rotation of the signal-ii'heel, and until the eut-away por-V tion arrives opposite the hroyectlon 61' thereof. rlhe cut-away portion of the cani is arranged opposite the long interdental space of the signal-Wheel, which occurs betiveen and is designed to differentiate the rounds or the signal. The signal-key will be in its open position between the rounds of the signal, and its pin 52 will then be disposed beneath the prop at the time said prop arrives at thecut-aivay portion, so that the prop, will be held in elevated position during the passing of said cut-away portionby the signal-key, unless it should so happen that the signal-key is held in or restored to closed position by other means, as, for instance, by `'abnormal position of the boX controller or the return movement of the 'locking-.member to` normal at the "completion of an alarm. A

The time consumed in movingthe signalivheel from the position shoivn in Fig, l to the positionV showny in Fig. 5, to disenga'ge the signal-key, is of longer duration than the longestvclosure in any signal,'and it is v during `this time that the boX is placed under the control of the circuit, as will be described, so that if another signal isbeing sentover the line, or there.: is troubleonthey line, the signal which is about yto'be sent will be delayed.

The delay of the signal is Controlled by y f thenonfinterference magnet 65, thearma- ,ture 66 of Which'is arranged on the lcontrollinglever 67, herein termed the' boxcontroller, which is pivoted `at 68.

A pin ,54 of cylindrical formation and slabbed'o on its underside is extended,v laterallyfrom the box-controller and norn attracted position, so that. While the signalkey is in open position the armaturewill be held in its attracted position. Thus during holds. the signal-key inits closed the signal will likewise be'delayed` A lAn attempt to send thedelayedsignal'is subsequently made at each 4revolution loffthe it-iss? the normal operation of the box, in case the line is clear, the armature Will be repeatedlyV held in its attracted position, when the cir-- cuit is opened by the-signal-lrey. In case the armatnureis orV should be .retracted While the signaldrey is in its closed position?` `then said pin 54 Will be vmoved to one side of the signal-key and into its path of move.-

ment, and in such position Will act to prop` and thereby hold said key in its closed position, until the armature is again moved intoits attracted position, so that no signal Y can then be sent by said key, notwithstanding the train is running.

In case another signal Ais being sent over the line, or there is trouble on the line, the

non-interference magnet lwill respond to Ysuch condition du'ringthe prolonged period of time Which follows the pulling of the box and precedes the first opening of the signalkey, and will 'move thepin 54: into position r to hold the signalkey in its closed position,

notwithstanding the signaling-train is 'run ning `and the prop has been properly moved into its disengaging position,`thus the sendingof the signal Will be delayed.

After the armature is moved into its `retracted position for the purpose ofcausing the signal to be delayed the stopping-means will be disconnected from the signalingtrain.

As a means for accomplishing this result,

troller, which, when the armature is retracted, is moved into the path of movement Y of the tail 72 of the dog '31, so that upon engagementv thereivtih said dogwill be 4moved to disengage the pin 30, as shown in Fig. 8. Said pin 30 then continues its or-' bital movement v vith thev train-Wheel 20, and the train continues to run', but the stopping-means is disconnectedfrom the tra-in and remains at rest, and, as' the boa-controller When thus retracted-also engages and position,

be started. For. the accomplishment of thisA result apin 7 5 is arranged ,on one'ofvthe train-wheels, as 2O for' instance, which wheel. it will be noted, is secured to the sig:

nal-wheel shaft, and' during each rotation of said Wheel, said pin passes a lprojection 76'on the box-controller, as shown in Fig. 2.

.Said pin however normally occupiesthisy l position opposite said projection.V

When the armature is inits retracted position, as it will be While the signal is being delayed, said pi-n in its orbital movement `'Will engage said projection 6 andfmechanically move the box-controller and armature into attracted position. This Willfbe done n during the time the notch in,-cam.63 isbe- 'neath the projection 61 on the propl and,-`

While said prop is in its propping position, Which it assumed instantly the notch passes Abeneath it, as the key itself, on account `of retraction of the armature, was then heldin closed position by said retracted armature.

After the restoring pinf 5 passes the proj ection 76 on the box-controller, said controller Will thenv be left under control of the magv net until the lirst tooth of the signal-Wheel passes beneath the signal-keyY as Was the case When theboxvvas iirst pulled, The period of time elapsing While the armature is' thus leftv under control of its magnet and before'the key can thereafter open the circuit is longer than any closure in a Signal and vif the circuit remains continuously closed during this period, it indicates that; no signal is then'usmg the line, and the key` is then free tolbegin its signal. In case the armature is not held bythe non-interference magnet during the Whole of this time,then it will again resume its retracted positionto again lockthe key during the succeeding whereupon thetrain will then engage and drive the. stopping-means until the notch of the disk 36 arrives in position for reengagement of the 4locking-member 39, and the train will bestopped. In case the line Was not free of other signals or in condition to send the attempted signal up to such time then the delayed'signal will notbe sent.

For the accomplishment of these results.

a .counting-device is provided, adapted to be moved one step for each round of the signal, or for each attemptto send a round of the signal, Which,v as here shown, comprises a mutilated ratchet-wheel 80, having a series of teeth adapted to be successively 'engaged by the aforesaid `pin 75, on the train-Wheel 20, or by other means operated by the signaling-train on or at the end of each round of the signal, to move' it intermittingly, andV having asingle long tooth 8l, also adapted to be engaged by said pin 75, and having next said long tooth a void or interdental space. Said ratchet-Wheel is mounted loosely, for convenience, on .the

Winding-shaft, and it has a circumferen- I tially grooved hub 83;*and a spring 84 is attached at one end to' the'Wheel, and at the other end to a pivoted member 85, or it may be to some other point. This spring is arranged to be Wound upon said hub, in the groove thereof, as the ratchet-Wheely is intermittingly rotated, `and is employed to return the ratchet-wheel to its normal position, when so ypermitted to act'. A

. The member 85 1s designed lto serve as a l stop to hold the ratchet-Wheel in its normal position, as shownby dotted lines Fig. 2,

and also as a pawl to hold the ratchet- Wheel in any of its intermediate positions. This member is pivoted at 86, and has a nose 100, arranged for engagem'entwith the long tooth 8l, and has a projection 89, ar-, Vranged for engagement with the teeth of the ratchet-Wheel. Said member 85 is movable ony its pivot into and out of co-active relation with theteeth of the ratchet-Wheel, and I' normally is so held that its projection 89 is out of the path of movement of the short ratchet-teeth. To move thisv member a long slot 87, is formed in it which receives a projection on a member 88, lwhich is secured to the shaft of the locking-member,

so'that upon a lifting movement of the locking-member said member 88 may be correspondingly lifted. Thel Slot 87 in lever 85 is -so shaped that When member 88 islifted the member 86 ,can move intov the position shown in Fig. 7, whereupon its projection 89 will be inposition for co-action with the teeth of the ratchet-Wheel, but when the` locking-lever drops it will again raise lever 85. Tlie'spring 84' being attached to said n'ember 85 serves to yieldingly hold it in s lengagement with the ratchet-teeth, permitting it to'yield'as the ,teeth of the ratchet- Wheel pass the, projection 89.

Thus it will be seen that the co-active relation of the components of the countingdevice are controlled by the looking-member,

which forms a component part of the`stop p ping-means, and the counting-device Will be active during the time the signaling-trainv yis running.

During the running of the train, and at the end of each`round-v of the signal, the I pin 75, willengage and move the ratchetwheel 80 one step, and said Wheel will be held bythe member 85, but as soon as the stopping-,means resumes its normalor stopping position and its locking-member enters the notch of the stop-Wheel, themember` 85' will be returned to its normal position, and having thus disengaged the ratchet-Wheel said ratchet-Wheel is permitted to resume its normal position by the action of the spring 84.

In case the line is free, and the stoppingmeans admits of, say,` four rounds of the signal being sent, the only function subserved by the counting-device Will be vthose above-described.4 In case, however, the line' is not free and the signal is delayed, and the stopping-means 'is-disconnected yfrom the sig- Y naling-train, then the' ratchet-'Wheel vvillibe successively advanced step by stepfor a pren determined number of rounds of the signal, say eleven rounds,`When its long tooth S1 will arrive in position for engagement with the pin 75; and a pin 90, \vhi'ch is extended Alaterally from said tooth will engage the end of the box-controller, as represented in F ig. 8,- and as the train continues to run the box-controller Will be partially returned and thereafter'held by the ratchet and pin in an intermediate position, .butJ still out of elfective ield of the non-interference magnet.

Suchl artialreturn movement of the b cX- controler is sufficient to move the pin 70 out of engaging'i'position With 'the tail of the ldog lpermitting movement of said dog, so that the pin 30 will thereafter engage.

, said dog, and thus connect the stopping-v means with the train., Said stopping-means ivill be thencontinuously driven by the train, in regular manner, for the sending of the delayed signal, which, however, may or may not be sent, depending up'oii the condition of thecircuit, but at the end of the predetermined number` of attempted rounds the locking-member will enter the notch of the stop-wheel and stop the train, so that the delayed signal will not be sent.

Villiether or not the delayed signal is sent it will be observed that lthe stopping-means will stop the train', and the counting-device is thereby ycaused to resume its normal position, the co-active relation of its component parts becomingY disengaged. Hence Y Will be seen that aftermany attempts to send adelayed signal during an allotted period of time, the signaling-train' is stopped, and' all of the component parts of the box caused to. resume their normal positions and long before the box has exhausted its round capacity, so that the boX must not onlyl be again pulled to send its signal, but that it.

' Will have ample capacity for sending each signal when so required. Y

During the many attempts to automatically commence `and send a delayed signal it will be Lnoted that in case any attempt is successful., the counting-device will act accordingly, tol count it outand then Will be returned to Ynormalrvvhenev er the stopping- Ameans has been connected With the train and has been driven by the train for its fullV period of time, and has resumed its normal position.

i Whenever the locking-lever is permitted to'resume 'its normal position Athe pin 56 thereon Will engage the extension 55 on the signalekey, and will restore and hold said key in its closed position so that the prop` canrpass beneath Ait to occupy a position to prevent said key opening when the boX is again pulled anduntil the signal-wheel has been advanced to engage the key.

As here shown, the armature and box-controller have associated With them. an improved form` of tension so constructed that as the armature retracts the tension rapidly increases in leverage, whereby the armature will be held in retracted' position against attraction of its magnet even though the strength of the current varies considerably and increases much ,beyond the y normal amount. Such arrangement insures correct Working of the non-interference devices even under great variation of current conditions of the circuit, which variations are of advantage at time' of signaling toincrease speed otcorrect signaling. This tension device consists of an arm 102,` attached to thel box-controller land extended above its pivot for a considerable distance, to the upper endportion of which one end of a link 103 is loosely connected, the other end of saidlink being connected to one end of a spring 104,

A.,and the other end of said spring being loosely connected to an adjusting-screw 105 much belowthe pivot.Y '-The line ot force o the tension when the armature is in attracted positionvis then near the pivotal point of the armature so that a small current will hold the armature attracted.y Y y As the armature is retracted the uppei' end of the arm 102 carries the line of force of the'spring away fromv said pivot and thereby-rapidly increases the leverage of said.

spring against attraction of the magnet, tending to hold the armature retracted even lwhenfthe vmagnet is iniuenced by an` ex'- current.
